Description

The author's certificate No. 42835 describes a device for mixing fibrous materials, consisting of a system of conveyors and feeders, in which are located. above the storage sheds, the conveyors consist of separate hinged trays, loaded by means of rotating brushes, which are used to drop the fibrous material from the feeding conveyor.

The unloading of the fibrous material from the laboratories in this device is carried out by means of a needle-shaped endless grid equipped with slats moving with needles and serving to control the grating of the fiber.

In the proposed modification of the device, there is a conveyor between laboratories equipped with an unloading carriage, and a system of cascaded conveyors - a transverse, Scottish conveyor belt - is used to transfer the fibrous material from it to the laboratories.

and a floor conveyor for folding beds in the storage sheds.

The device is based on a principle similar to that used in the manual manufacture of mixes, but with complete mechanization of all mixing processes, consisting of making up the bed from all the components of the mixture, then selecting it vertically, then re-making the bed out of material taken from the primary bed and finally, in the final selection of material vertically from the secondary bed.

In the schematic drawing of FIG. 1 shows a vertical longitudinal section of a device for mixing fibrous materials according to CD of FIG. 2; FIG. 2 shows a cross-sectional view of it according to AB of FIG. one; FIG. 3 - view from above.

For the formation of beds there are two labazes / and II, each with a capacity for the entire batch of mix. In the first labaz / bed is made up of individual components of the mixture when filling this labaze, and in the second labaze // bed is made of material selected vertically from the first bed. Work in the labaza is performed simultaneously and while the first labaz is filled with the components of the new batch of mix, the manufactured mix of the previous batch is unloaded from the second labaz. The loading time and the unloading time for the labazes are the same, therefore the bed making in the first storage shed and the selection from the second one are completed simultaneously. After the bed has been made in the first warehouse and the second warehouse is cleaned, the bed is transferred from the first warehouse to the second, and the material taken vertically from the primary bed from the first warehouse is mechanically spread out in horizontal layers in the second warehouse, forming the secondary bed.

At the end of the pass, the described cycle of the installation. repeats with a new batch mix.

The folding device of the device, which serves to lay the fibrous material of the mixture into bed, consists of a main conveyor 4, an unloading trolley with a cross conveyor 6 and a folding trolley with a pair of special conveyors: a narrow oscillating conventional Scottish conveyor 7, a wide conveyor 8 and a sealing drum 21. The conveyors form cascaded system.

The bed layers in the storage shed are formed due to the continuous dumping of material from the wide conveyor 8 of the folding trolley into the storage shed and the continuous movement of the trolley itself from one end of the storage shed to the other. To warn you that the material has become lumpy in the form of large lumps, it falls into separate shreds with a windworm when it falls.

On the wide conveyor 8, the material is superimposed on an oscillating narrow conveyor 7, laying the material on the surface of the wide conveyor with zigzag ribbons, being superposed slightly displaced from each other.

On the oscillating conveyor 7, the material is fed by a transverse evacuating conveyor 6 located on

unloading trolley and dumping material on the surface of the conveyor U in the place corresponding to the center of his swing. |

The purpose of the discharge car is to unload the material from | 1 main conveyor 4 at any point of its bearing surface h.

Such a device for the unloading carriage, with a parallel arrangement of the main conveyor 4 and labazes / and // for the bed, makes it possible, as the trolley moves continuously to discharge material along the entire length of the labazes. The connection into one system of folding and unloading carriages and the conjugate reciprocating, their forward movement along the sheds allows the material to be dumped into the sheds in uniform layers that form during sequential laying of each other: bed civfecKH., 1

In the case of the primary bed in the storage shed /, the material on the main | the conveyor 4 of the folding device is supplied by the modular trans-1 porter 3 from the feeders /, the output grids of which 2 throw the material onto its surface. t6opHbil |, the conveyor 3 is located below the end part of the main transport-1 ra 4. Therefore, to lift the material to the level of the main conveyor -, its 1 rear branch is bent down, and the front branch of the collecting conveyor 54 is respectively raised. When eton, | the bearing surfaces of both fanspor-1 terovs at the point of lifting are in contact; and clamp the lifted material, not |: giving him the opportunity to fall into "from. I

In the case of the pass, i.e. compilation; secondary bed in labyze / L J al comes from the selector pervich- f

The bed of the device ejecting material from the first warehouse / onto the surface of the longitudinal conveyor 18. This conveyor 18, located along the warehouse I, receives material from the pick-up device all the way through the warehouse and via the transverse conveyor 19 transfers it to the collecting conveyor 3 by which material, already described in order, is transmitted to the main conveyor 4.

The unfolding trolley serves both lab-stores alternately, why it is connected to the unloading trolley, respectively, from one side or the other. In this case, the transverse conveyor 6 of the unloading carriage must be turning on both sides so that its output end can dump the material onto the oscillating conveyor 7 of the folding carriage, regardless of its position above one or the other storage shed.

To ensure the required and uniform density of the bedding in the storage shed, a sealing drum 21 is installed on the folding trolley, which, moving together with the trolley and pressing on the bed, rolls it up to the required density.

Since the lower layers of the bed will be compacted under pressure from them on the upper layers, the need for additional compaction of the bed in the lower layers is eliminated. Therefore, the sealing drum 21 is lowered down only half the height of the warehouse, on which it begins to act as soon as it reaches the level of the poured material. As the second half of the bed is laid, the drum begins to move up vertically, receiving movement from the ratchet to a certain height for each stroke of the cart along the storage area until it reaches its extreme upper position.

The selection device of the device, which serves for the vertical selection of material from the bed of the mixture, is a movable mechanism of a caulking lattice 10 with a vertical working surface and equipped with mechanisms for controlling and

the layer of the material to be taken out; and to clean the lattice from the material, to remove it to the outside.

The controlling mechanism consists of a fixed pressure pad 11, an oscillating swinging ridge 12 and a swinging compactor 13.

The pressure pad // serves to seal the upper layers of the bed and, thus, create the same operating conditions of the capping screen 10 over the entire surface of contact with the bed of the mixture.

The leveling of the layer of material taken from the bed by the collar grill 10 is carried out by a ridge 12, taking away large lumps of material and discharging its excess from the surface of the grill.

The shreds of material dropped by the comb 12 along the broad front plane of the pressure pad // descend and connect to the top layer of the bed, to which they are clamped by a rocking compactor 13, which prevents the material from accumulating on the surface of the pressure pad.

The cleaning mechanism consists of a clearing collar 14, a grate 15 and a wind 16.

The cleaning grid 14, due to the greater speed of movement than the speed of the working selection grid 10, as well as due to the thicker prickly floor and the almost vertical nozzle of the pegs, captures the material located on the pegs of the selection grid 10 and, taking it with you, brings it to discharging conveyor surface 17.

To prevent the premature falling of the material from the pegs of the cleaning grid 14 and the clogging of the already cleaned surface of the collection grid 10 at the time it bends around the guide roller, as well as to protect the material from falling on the edge of the discharge conveyor 17, a supporting platform 22 was installed, the horizontal surface of which overlaps the distance between the bend line of the selection grid 10 and the discharge conveyor 17, setting somewhat over its edge. After the passage of the material over the entire surface of the supporting platform 22, it loses the support it creates from below and falls under the influence of gravity from the pegs of the cleaning grid 14 onto the surface of the discharge conveyor 17, which leads to the outside.

The grate grate 15 and the wind 16 contribute to the release of the peg material from the cleaning grid 14.

The rod of the grate 15 passes along the cleaning grid 14, between the rows of its spikes, and in the working part of the cleaning grid, i.e., at the place of its interaction with the selecting grid 10, as well as at the place of its splitting above the surface of the supporting platform 22, The bars of the grate lie at the base of the pegs, not preventing them from seizing and carrying the material. In the place where the supporting horizontal plane of the safety pad 22 ends, the grate changes direction, and the departure from the base of the pegs of the cleaning grid gradually goes beyond their vertices, creating an inclined lattice barrier for the fiber and causing the bulk of it to fall off the pegs of the cleaning grid.

The wind 16, the blades of which pass in the immediate vicinity of the grate J5, at the moment of its release of the rods beyond the pegs of the cleaning grid 4, knocks down individual pieces of material that can either hang onto the rods of the grate / 5 or pull through the necks of the cleaning grid 14, thus protecting both grids from clogging with the material.

Since separate scraps of material may remain on the grate 10 after it has been cleaned, which, when the lattice moves further with the spikes lowered down, will drop from it and thus litter the labaze floor, in order to prevent material from similar ingress, a shield 20 is placed under the grid 10. extending parallel to its surface all the way from the supporting platform to the lower guide roller of the grid.

The material ejected by the discharge conveyor 17

conveyors 18 running along the storage sheds are diverted for transfer to either a folding tool or further processing.

During the initial powering of the device by the components, i.e., when the primary bed is made up, no dosage of material is performed. However, in order to create a more homogeneous working condition of the capping screen, along the entire bed selection plane, the device should be powered at the same time by a variety of fiber properties. To do this, we can recommend a preliminary distribution of all types of raw materials to individual feeders so that in each segment of time they feed to the conveyor material consisting of individual components that differ sharply in their properties,

It should be especially emphasized that the preliminary grouping should be carried out not by type of raw material, but only by type.

For example, a blend is made of three main types of raw materials in the following proportion; All sorts of wool are natural and rovnichny scrap 25 / o, all sorts of wool are artificial and short-fibrous obraty (peeling, towing, etc.) SOVo and cotton.

With the indicated subdivision of the mix according to the types of raw materials, assuming the productivity of the feeders is the same, with four feeds, the following feed order is planned, namely: one feeder is allocated to the first group of raw materials, two feeders is allocated to the second group of raw materials and one feeder .

In a bed made with such nutrition, there will be no sharp edges between the properties of the individual layers, and the conditions for its selection with the Kolkova lattice will be most favorable.

In the process of pretreatment of the material, before mixing, it must be divided into fairly small scraps, because in this case, on the one hand, the conditions for the operation of the selection device are facilitated, and on the other, a more thorough mixing of the mixture is achieved, because Saving from small shreds, it is possible: but a more uniform distribution of “th over the area of each layer of the bed; therefore, before mixing, the material must be developed in a pinch mask.
