Description

Water pipe cleaning method and equipment

The invention relates to a water pipe cleaning method and equipment, in particular to a cleaning method and equipment capable of forming a circulation circuit in a pipeline as the inventor of its application.

In addition to water for people to drink, it can also be used for cooking and cleaning; general household water and industrial water are supplied by pipelines from reservoirs, and are sent to the water supply unit through the water source in the motor extraction pipeline. It is used to connect the water pipe between the faucet and the water supply unit. When you use it, you only need to open the faucet, and the water stored in the water supply unit will be sent to the faucet for use by the people through the water pipe.

Since the water source is transported from the reservoir through the pipeline, it must contain impurities and minerals. When the water is transported through the pipeline to the faucet, it will more or less entrain dirt in the pipe wall, and the inner wall of the water pipe will be in contact with the water for a long time. Scales are generated. When the curved pipes flow, oil and debris trapped in the water will also adhere and get stuck on the inner wall of the water pipe, which not only pollutes the transported water, but also causes the water pipe to rust on the pipe wall.

However, when the environment is cleaned, people will always clean the water supply unit, but they have never thought about cleaning the water pipe. After a long time of use, sludge, algae, germs, and various heavy metals contained in the water will be attached to the water pipe. On the wall, coupled with the corrosion caused by the long-term use of the water pipe, the degree of dirt can be imagined, and the thickening of the water pipe wall due to the accumulation of dirt and dirt will not only make the water output of the water pipe smaller, when drinking There is an extra diet crisis, so regular cleaning of water pipes becomes an important part of household cleaning.

At present, water pipe cleaning operations use pipeline cleaning machines, such as Taiwan's new patent announcement No. M366426 "water pipe cleaning device", M378045 "water pipe cleaning equipment", M385409 "pipe cleaning machine", etc. A liquid storage barrel is provided to install the cleaning agent, and the agent is sent into the pipeline for cleaning through a high-pressure gas source. However, this method needs to pressurize the high-pressure gas to the liquid storage barrel, and transfer the medicine from the liquid storage barrel to the pipeline to be cleaned. Since the liquid storage barrel is accommodated in the pipeline cleaning machine, its capacity is limited. When the pipeline to be cleaned is longer, more reagents must be used. In this case, the reservoir must be filled repeatedly with the reagents to be able to supply the dose of the drugs in the pipeline; The problem of residues and chemicals eroding the wall of the water pipe, which pollutes the water flowing through the water pipe, not only cannot improve the quality of the water through cleaning the water pipe, but also aggravates the problem of residual medicine in the water, and the pressure cleaning process can not know the inside of the pipe Pressure can easily cause bursting of water pipes.

Today, the inventor upholds many years of rich design and development and practical production experience in the related industry. Before people pay more attention to the quality of life, they will study and improve the existing water pipe cleaning machine, and provide a water pipe cleaning.

In the actual implementation of household water pipe cleaning, the water supply unit (1) refers to the water tower or tap water end. When the water supply unit (1) leads the water source to the first pipeline (2) in the house through the water inlet end, the first The pipeline (2) is connected to a pipeline and passes through a heating device (5). The heating device (5) refers to a device such as a water heater, solar energy, etc. that can cool cold water, and is formed by the heating device (5) A second pipeline (3) for hot water circulation; however, the first pipeline (2) and the second pipeline (3) are respectively provided with a plurality of first and second water outlet switches (21) , (31), here, for example, there are three outlets (21) [cold water outlet faucet] and first Two outlet switches (31) [hot water outlet tap]; however, the first and second outlet switches (21), (31) have two independent outlet taps, or integrated in one outlet tap Ball valve to control the water output separately.

First of all, please refer to the first to second and fourth figures. When performing (a) the step of emptying the water source, the inlet end will be closed by a valve (A) to supply water, and through the first and second outlet switches (21 ), (31) Drain the water sources in the first and second pipelines (2), (3) to keep the pipelines clear; then, (b) the installation step is to the first pipe A cleaning device is correspondingly installed at the end of the road (2), and a water inlet valve (22) is provided at the outlet end between the first pipeline (2) and the cleaning device. The cleaning device is integrated with the cycle unit (43) ), the air compressor device (44), the liquid storage tank (41) and the pump (411) are in a housing device (B), however, the above components can also be independently installed on the On the first pipeline (2), that is, the one-wave unit (43) and an air compressor (44) are installed correspondingly on the first pipeline (2); please refer to the third diagram before passing (b1) The pressure detection step is to close the first and second water outlet switches (21) and (31), and pressurize the first and second pipelines via the air compressor (44) ( 2), (3), through the input pressure index to detect whether there is leakage or sudden pressure drop in these pipelines to know whether the pipeline is broken or leaking. If there is a problem of cracking or leaking, it cannot be After the cleaning step of the water pipe is continued, when it is confirmed that there is no rupture or water leakage, the next step can be continued.

Continue to perform (c) the step of assembling the communication valve, mainly in the first and second water outlet switches (21) and (31) of each group in the first and second pipelines (2) and (3) A communication control valve (45) is set between them, and the first and second water outlet switches (21) and (31) are opened to make the first and second water outlet switches (21) and (31) communicate. Furthermore, each group of outlet switches are connected, so that the first and second pipes (2) and (3) form a circulation circuit; however, the communication control valve (45) is correspondingly assembled on the first, The second outlet switch (21), (31) The opening end, if it can not be directly assembled with the communication control valve (45), it can be connected to the first and second water outlet switches (21), (31) to form a connection pipe (451) Then, the connection pipe (451) is combined with the communication control valve (45) to achieve the effect of communication. In addition, a connecting pipe (451) can also be formed between the first and second water outlet switches (21), (31), and the first and second pipelines are communicated through the connecting pipe (451) (2), (3), the connection pipe (451) is regarded as a function of communicating with the control valve (45).

Next, in step (d) of the liquid storage tank, the liquid storage tank (41) contains cleaning acid liquid, and the cleaning acid liquid can use a variety of suitable chemical liquids, and the liquid storage tank (41) is installed At the end of the first pipeline (2), it is located at the rear section of the frequency unit (43) and the air compressor (44), while the other end communicates with the second pipeline (3), A water outlet valve (32) is provided at the liquid inlet end of the second pipeline (3) and the liquid storage tank (41). When the liquid storage tank (41) delivers clean acid liquid through the pump (411) for circulation When the circuit is cleaned, the heating device (5) will be disconnected first.

Further, when the liquid storage tank (4) is integrated in the housing device (B), the second pipeline (3) is connected to the liquid inlet of the liquid storage tank (41). When the cleaning acid liquid uses a heating method to improve the cleaning efficiency of the chemical liquid, such as citric acid, it further includes a heating component (42), and the heating component (42) can be installed in the liquid storage tank (41) ) Or at the outlet and inlet of the conveying clean acid liquid, mainly used to heat the clean acid liquid; however, the clean acid liquid can also be heated and then introduced into the storage tank (41) for further use It can be heated by the heating device (5) when the cleaning acid flows to the second pipeline (3).

After the assembly of the above pipelines is completed, the cleaning acid solution is introduced through the first pipeline (2) through the outlet of the liquid storage tank (41) through the pump (411) through the (e) circulating cleaning step, using the pump (411) The flow is cleaned in the closed circulation circuit, and then circulated back through the cycle unit (43) and the air compressor equipment (44) Pressure and vibration are generated in the road, so that the cleaning acid liquid dissolves the dirt of the pipe wall in the circulation circuit, and pressurization and vibration make the stubborn dirt fall off, and the cleaned acid liquid after cleaning passes through the second pipeline (3) The end is returned to the liquid storage tank (41). Of course, one wash does not remove all the dirt from the pipe wall, so the clean acid returned to the liquid storage tank (41) again passes through the pump ( 411) Introduce into the closed circulation circuit and clean the first and second pipelines (2) and (3) by repeating the cycle for a period of time; and how to judge whether to clean it, that is, by replacing the dirty cleaning acid To make a judgment, the dirty cleaning acid after cleaning can be replaced or added with clean cleaning acid according to the dirty situation, and the pipeline is completely clean when the cleaning acid after circulating cleaning is no longer dirty.

After cleaning, perform (f) clean water cleaning step, which shuts off the operation of the liquid storage tank (41) and pump (411) through valves and switches, and at the same time, introduces clean water into the circulation circuit and passes through the cycle unit (43) Continuously pressurize and oscillate with the air compressor equipment (44), so that the clean acid in the circulation circuit can be flushed out, so that the water pipe cleaning is completed.

In addition, please refer to the fifth figure. When the cleaning process, because the dirt is caught in the pipeline and cannot be led back to the reservoir (41) through the circulation circuit, it is tied to the first and the first A backwashing device (6) is provided at the end of the two pipelines (2) and (3) and located at the front stage of the frequency unit (43) and the air compressor (44). The backwashing device (6) includes a A backwash manifold (61) and a second backwash manifold (62), the first end of the first backwash manifold (61) is connected to the first pipeline (2), and the second end is connected to the The second pipeline (3) is provided with a first valve (611) on the first backwash manifold (61), and the first end of the second backwash manifold (62) is connected to the first Two pipelines (3), and the second end is connected to the first pipeline (2), and a second valve (621) is provided on the second backwash manifold (62). The aforementioned cleaning process is a positive washing method, that is, by opening the water inlet valve (22) and the water outlet valve (32), the cleaning acid liquid is repeatedly circulated and cleaned in the circulation circuit. When the pipeline at the return side is blocked by the dirt catch, the system It can be cleaned and continuously cleaned by the backwashing device (6), that is, the water inlet valve (22) and the water outlet valve (32) are closed, and the first and second valves (611), (621) are opened, Make the first and second backwash manifolds (61), (62) conduct, after starting the cleaning equipment, the liquid storage tank (41) is actuated by the pump (411) to introduce the cleaning acid from the first tube The circuit (2) passes through the first backwashing manifold (61) to the second pipeline (3), while continuing to pressurize and oscillate through the cycle unit (43) and the air compressor (44), and then is guided by the circulation circuit Back to the first line (2) and through the second backwash manifold (62) to the second line (3), and finally back to the storage tank (41) and continue the backwash cycle, so, Dredge the pipeline effectively and continue to clean it.

However, the above-mentioned backwashing device (6) is erected in a state where the forward washing pipeline cannot be unblocked; of course, the backwashing path can also be used as the main cleaning circulation pipeline from the beginning. As shown in the sixth figure, the outlet and inlet ends of the liquid storage tank (41) are appropriately changed so that the liquid outlet of the liquid storage tank (41) is connected to the pump (411) and connected The second pipeline (3) pumps clean acid solution to the second pipeline (3), and the liquid inlet of the liquid storage tank (41) is connected to the first pipeline (2), In order to recover the clean acid solution, the corresponding pipeline changes due to the arrangement of the outlet and inlet of the liquid storage tank (41). In contrast, the pipeline change is also required in the installation step of (b). The cycle unit (43) and the air compressor (44) must be assembled correspondingly at the outlet of the liquid storage tank (41), pressurized and shaken with the cleaning acid, so its (b) installation step, Then it is changed to the installation of a one-wave unit (43) and an air compressor (44) on the second pipeline (3); and other components such as heating components (42), communication control valves (45), etc. No change; by this, according to the above-mentioned circulation method and steps, the cleaning acid can be introduced into the second pipeline (3) through the pump and return to the storage through the circulation pipeline through the first pipeline (2) The liquid tank (41) is recirculated and washed through the second pipeline (3) and the first pipeline through a repeated circulation mechanism, which also achieves the effect of complete cleaning. In addition, after the cleaning is completed, the clean water cleaning step (f) is also performed. The operation of the liquid storage tank (41) and the pump (411) is closed by valves and switches. At the same time, clean water is introduced into the circulation circuit and passed through Cycle unit (4 3) Continuously pressurize and oscillate with the air compressor equipment (44) to flush out the clean acid in the circulation circuit. In this way, the water pipe cleaning is completed.

Through the above-mentioned structural devices and steps, it can be seen that the communication control valve can make the communication between the pipelines, so that it can achieve the function of circulating cleaning; however, if it is purely by circulating cleaning, it can pass through the communication control valve (45) or the connection pipe (451), when the communication control valve (45) is used, the water flow status can also be checked through the opening and closing of the valve. When the water flow is small, it means that there is still a pipe that is not completely cleaned. The dirt catch can be further strengthened. At the same time, it can also be strengthened and cleaned for a certain section of the pipeline through the opening and closing of the communication control valve (45), so as to use the communication control valve (45) as the water inlet and outlet connection Point, you can switch the circulation pipeline, or the pipeline that can form a segmented circulation.

However, the foregoing embodiments or drawings do not limit the product structure or usage of the present invention. Any appropriate changes or modifications by those with ordinary knowledge in the technical field should be regarded as not departing from the patent scope of the present invention.

In summary, the embodiments of the present invention can indeed achieve the expected use effect, and the specific structure disclosed by it has not only not been seen in similar products, nor has it been disclosed before application, and has fully complied with the provisions of the Patent Law To meet the requirements, I filed an application for a patent for invention according to law, and pleaded for the review, and granted the patent.
