Definitions
- the present invention relates to a process for granulating plastics and / or polymers, in which melt coming from a melt generator is fed to a plurality of granulating heads via a starting valve having a different operating position, by means of which the melt is granulated.
- the invention further relates to a granulating device for granulating plastics and / or polymers with a starting valve, which has at least one Schmelzeerzeu- geran gleich, at least two Granulatoran Why and a switching network for connecting the Schmelzerer Wegeran gleiches optionally with at least one of the granulator, wherein in each case at least two granulator connections a granulating head connected and connected to the Schmelzeereuge- ran gleich a melt generator with variable melt volume flow.
- the invention also relates to a starting valve for such a granulating device with a melt generator connection, a granulator connection and a melt channel for connecting the melt generator connection to the granulator connection.
- These starting valves comprise in the melt channel, which connects the inlet opening of the valve at the melt generator connection with the outlet opening at the granulator connection, a starting switch which switches the connection of the melt generator connection with the granulator connection in the production position, while in its starting position the melt flow from the outlet opening on Keeps pelletizer connection, ie this shuts off and the loss of melt deflects, so that the Schmelzeer Wegeran gleich entering melt flow does not reach the Granulatoran gleich, but instead exits at a bypass opening of the valve and regularly flows simply on the ground.
- the starting point is switched to its production position so that the melt flow in the starting valve flows to its granulator connection and then through the granulator connected there Pellets is processed.
- DE 696 21 101 T2 describes the possibility of viscosity change within a compounding process with subsequent granulation in a corresponding large-scale production plant with at least 1000 kg / h of power.
- Two granulating heads are connected to the valve downstream of the melt generator, so that by switching the valve highly viscous material can be applied to one granulating head and low viscosity material to the other granulating head.
- the problem of starting losses here is not solved, but should not be eliminated in a conventional manner until reaching the respective operating point granular material via a bypass opening.
- a granulating device is described in DE 197 54 863 C2, in which two granulating heads are connected to a 1/3-way valve, so that either one or the other granulating head can be selected for a color change from black to white material or vice versa .
- a central bypass outlet is provided in the valve, via which, after a color change in the melt generator, material of the new color is removed until the last impurities have also been taken away. This is in relation to the aforementioned objective of reducing start-up losses and expensive materials. to reduce alabae, rather counterproductive than helpful.
- a multi-way rotary valve for granulating known by means of which high molecular weight plastic melts can be distributed or divided. However, the problem of starting losses is not addressed in this document.
- the present invention is therefore based on the object, an improved granulation, an improved granulating and a starting valve to create the aforementioned type, which avoids the disadvantages of the prior art and the latter develops in an advantageous manner.
- a start-up of the granulation with the lowest possible starting losses and as continuous as possible working without interrupting the process and Neuanfahrbuchen should be achieved.
- the present invention is therefore based on the idea of using several granulating heads with different passage capacities and thereby increasing the total throughput window in order to be able to work largely continuously without interruptions and to shorten unavoidable starting operations by connecting granulating heads with small throughput capacities or with regard to the resulting Minimize start-up goods.
- a plurality of granulating heads with different throughput capacities are successively used for starting the granulation process, wherein first the melt is fed to a first granulating head with a smaller throughput capacity and then increases the melt volume flow and the starting valve is switched, so that the melt from the starting valve to a second granulating head with a larger throughput capacity is deflected.
- the use of initially a granulating head with the smallest possible throughput capacity shortens the time and thus the quantity of starting material until the melt producer reaches the throughput lower limit of the granulating head and the granulation process can be started. From the beginning of the granulation process at the lower throughput limit of said first granulation on no further Anfahrware attracted. The melt volume flow is increased quantitatively until the start-up valve can be switched to the second granulation head with the larger throughput capacity, during which time no Anfahrware obtained.
- the throughput window is generally presentedt, so that the number of unavoidable starting operations with resulting Anfahrware is reduced because at a possibly different reasons, if necessary, down the melt performance below the throughput lower limit of the larger granulating the melt can be switched back to the first granulating.
- the granulating device of the type mentioned has a control device for controlling the switch point of the starting valve as a function of the melt volume flow of the melt generator.
- the start-up valve can be switched to the granulation head with the smaller passage capacity at a small melt volume flow, while at a larger melt volume flow, the start-up valve is switched to the second granulation head with the larger throughput capacity.
- control device can fundamentally implement different degrees of automation, for example semi-automatic in that, upon reaching a melt volume flow which allows operation of the second granulation head with the larger throughput capacity, it is given an indication that indicates this to an operator and that after one corresponding input by the system operator, the control device then switches the starting valve in the aforementioned manner to the second granulating head with the larger throughput capacity, so that the melt stream is diverted from the first granulating head to the second granulating head.
- the control device can also be designed to be fully automatic to the effect that it automatically switches the starting valve to the respectively suitable granulation head when determining a corresponding melt volume flow.
- control device may have control means which switch the starting valve to the first granulating head with a smaller throughput capacity if the melt volume flow is below a lower capacity limit of the second granulating head with a larger throughput capacity, but above a lower capacity limit of the first granulating head, and the starting valve to switch the second granulating head when the melt volume flow is above the lower capacity limit of the second granulating head and still below a lower capacity limit of a possibly present third granulating head with even greater throughput capacity.
- control device may also have volume flow control means for controlling the volume flow, which is introduced by the melt generator in the starting valve.
- volume flow control means for controlling the volume flow, which is introduced by the melt generator in the starting valve.
- different melt generators with variable volume flow can be used, for example, the melt stream can be generated via a suitable screw extruder and at the same time be changed in terms of its volume.
- a gear pump between the melt generator and the starting valve may be connected in order to control the volume flow accordingly.
- the control device is advantageously designed such that it can also change the volume flow within the capacity limits of a granulation head, preferably continuously.
- the melt volume flow within the throughput capacity limits of the first granulating head can be increased continuously. Since granulation is already carried out with the first granulating head, no start-up product is produced, and as a result of increasing the melt volume flow, the plant is continuously driven onto the granulation process with the second, larger granulating head.
- the starting valve is only switched over to the second granulating head when the melt volume flow has been increased to the lower capacity limit of the second granulating head and / or the upper capacity limit of the first granulating head.
- the approach valve can be switched in a further development of the invention depending on the melt viscosity, the melt temperature, the melt pressure, degassing and / or reaching the necessary minimum volume flow from the starting position on the first granulating.
- corresponding device for determining preferably sensors for detecting the mentioned parameters, may be provided in device-technical terms, so that the control device can switch the starting valve in accordance with the corresponding signals.
- the mentioned parameters can also be estimated.
- the Anfahrventils from the starting position on the first granulator head also other parameters such. As color, filler incorporation or other melt or granule parameters are taken into account.
- the switching of the starting valve from the first granulator head to the second granulator head or from the n-th granulator head to the n + 1-th granulator head not only in response to reaching the necessary minimum volume flow for the second or n + 1 -ten granulator head, but alternatively or additionally done in dependence on other parameters.
- the start-up valve can depend on the granule size, the melt mass pressure, the melt melt temperature or other parameters, such as granule form, surface tackiness, agglomeration, double grain occurrence, crystallization effects, etc., from the first granulation head to the second granulation head. be switched lierkopf.
- the starting valve can be switched to the larger granulating head.
- this switching can then be carried out when the melt pressure of the melt rises above a corresponding limit value.
- Increasing throughput usually also increases the head pressure, which may be restrictive for some products, as damage due to shear may be due to pressure. As a consequence, the melt temperature of the melt may also increase too much, resulting in similar consequences. Again, switching can help.
- a critical deformation of the granules are used as a criterion, which arises when increasing the flow rate per hole.
- switching to the larger granulating head can also help here.
- From the granule size can be derived also other secondary Umschaltnotwendtechniken, but which are ultimately correlated with the grain size of the granules, namely the surface tack, the agglomeration, double grain, different crystallization effects due to different size and temperature of the granules and the like.
- the granulating heads connected to the starting valve have complementary throughput capacity ranges which preferably adjoin one another seamlessly. If necessary, the capacity ranges could also overlap, but to increase the throughput window as a whole, however, it is nevertheless true that the throughput capacity range defined by the two granulating heads is greater than that of only one granulating head.
- a first granulating head having a flow rate of 2500 kg / hr to 4500 kg / hr, a second pelletizing head having a flow rate of 4500 kg / hr to 7500 kg / hr, and a third pelletizing head having a granulating head Throughput capacity of 7500 kg / h to 12,500 kg / h can be used. It is understood that the capacity limits can be chosen differently, but they complement each other in a corresponding manner advantageously seamless.
- the granulating heads can be designed for different granulation processes.
- the granulating can form Unterwassergranulierköpfe.
- the granulating heads could also form strand granulating heads or water ring granulating heads.
- the granulating heads can also realize different types of granulation, for example, the granulating head with smaller throughput capacity can be an underwater granulating head, while the granulating head with higher throughput is a strand granulating head.
- the starting valve is advantageously designed such that the fastest and uninterrupted redirecting of the melt stream from one granulating head to the next granulating head is made possible.
- the bidirectionally operable start-up valve for different process stages has different flow paths for the melt, so that the start-up valve for a first process stage with a first flow path and optionally for a second process stage via a second flow path is operable. It can dispense the melt optionally via a first or a second granulator connection.
- the other, not operated flow path or Granulator connection can be cleaned at the same time as production via the operating flow path, so that the resulting dead times are eliminated. Nevertheless, the flow path or granulator connection which is not in operation remains at temperature, since the heat introduced by the melt naturally also heats the non-operated part of the starting valve.
- the starting valve can realize the multiple production paths starting from only one melt generator connection.
- the start-up valve has, in addition to the first granulator connection, a second granulator connection which can be connected to the same melt generator connection as the first granulator connection.
- the start-up valve has a switch point, which connects the melt generator connection with the first granulator connection in a first production position and the mentioned melt generator connection with the second granulator connection in a second production position.
- the polymer melt can be quickly redirected to one of the two nozzle geometries mounted on the granulator connections.
- the other nozzle geometry is so to speak in stand-by and is not used.
- By operating the switch point can be switched in seconds between the two possible production directions.
- the melt channel which connects the Schmelzerer Wegeran gleich either with one of the two Granulatoran nowadays, a Anfahrweiche that switches in its production position, the melt channel to the respective Granulatoran gleich while deflecting the melt flow in their starting position and gives to a bypass opening ,
- the aforesaid switching points for switching between the production directions and the starting point for the start-up procedure can basically be used separately be formed from each other. In a further development of the invention, however, they are coupled together, in particular formed by a common valve body, and actuated by a common valve actuator.
- the start-up valve may also have, in addition to the first and second granulator connections, a third or further granulator connection which can be connected to the melt channel.
- the switch point here is preferably designed such that it connects the third granulator connection with the melt generator connection in a third production position. Accordingly, the starting valve can even switch between more than two production directions.
- the start-up valve has a second production path completely separate from the first production path.
- the valve according to this embodiment has a second granulator connection and a second melt generator connection, which can be connected to one another by a second melt channel.
- the change from a first production process to a second production process can advantageously take place particularly quickly by releasing the initially used melt and granulator connections by means of quick-action couplings and, after minimal mechanical modification and a corresponding rotation of the starting valve itself, the starting valve with the second melt - And Granulatoran Whyn and corresponding quick couplings is mounted again between the melt generator and the granulator.
- the second melt channel is already preheated on the one hand in the purified state and on the other hand by the preceding production process, so that the new production process can be started quickly.
- a start-up switch is provided, which in a production position the respective melt channel turns on, so that the melt flow from the inlet opening of the respective melt generator port can flow to the outlet of the associated Granulatoran gleiches, and bypasses the melt flow in a Anfahr ein, ie the respective Granulatoran gleich shuts off and directs the melt flow to a bypass opening, so that in in itself known manner the start-up process for the new production process can be done.
- the crossover of the first melt channel and the crossover of the second melt channel are advantageously realized in a common valve member and actuated by a common valve actuator.
- a common valve actuator Only a control facial expressions for switching from starting position to production position of both production routes is required.
- the corresponding components, such as valve actuator, control electronics, etc. can be saved, so that this solution is distinguished by its cost-efficiency.
- Through-pass channels for both the first melt channel and the second melt channel and corresponding bypass channels for diverting the melt flow of the first melt channel and the melt flow of the second melt channel in each case to a bypass opening can be provided in the valve member.
- the Anfahrtechnisch formed by the valve member are advantageously designed so that both Anfahrenfin are simultaneously in their production position and at the same time in their starting position. In this way, if both production paths of the starting valve are used simultaneously, the corresponding production processes can be approached simultaneously. If only one of the two production paths of the approach valve is used, the unused production path is continuously opened so that it can be completely cleaned while the other production path is being used.

- melt channels 7 and 8 communicate with corresponding inlet openings 10 and 11 at the two melt generator connections 3 and 4 and with corresponding outlet openings 12 and 13 at the granulator connections 5 and 6.
- this option of the invention thus opens up a reduction of the loss amount per startup process by a factor of 2.78.
- this means that on the one hand less material losses are incurred, which must then be disposed of or treated and on the other a faster starting is allowed, resulting in less manpower and overall less handling effort (plastics must be at the exit from the starting valve down Bottom sucked and cooled, which of course directly affects the operating costs) means.
