Description

Technical Field

[0001] This utility model relates to the technical field of pipeline anti-clogging equipment, specifically to a novel filter material anti-clogging device for concealed pipe drainage. Background Technology

[0002] Drainage pipes are mainly responsible for rainwater, sewage, farmland irrigation and drainage, municipal construction, and household drainage. Domestic drainage pipes are mainly divided into plastic drainage pipes, metal drainage pipes, concrete pipes (CP), and reinforced concrete pipes (RCP). Concrete pipes (CP) and reinforced concrete pipes (RCP) are used for some large-scale agricultural construction or municipal projects. Household drainage pipes are mostly plastic drainage pipes and metal drainage pipes. One of the main problems with drainage pipes is that they can become clogged during drainage.

[0003] Underground drainage systems are widely used in agricultural drainage and municipal sewage discharge. They use buried pipes to drain accumulated water and sewage to improve the environment or ensure production. However, during drainage, silt, debris, and filter media particles in the water can easily accumulate in the pipes, causing blockages. Furthermore, traditional underground drainage systems lack effective anti-blockage measures, making unblocking difficult and often requiring pipe excavation. This is not only time-consuming and labor-intensive but can also damage surface infrastructure. Blockages can also increase drainage pressure, leading to increased energy consumption and potentially causing pipe rupture due to excessive pressure, thus reducing the pipe's lifespan. Utility Model Content

[0004] In view of this, the present invention provides a novel filter media anti-clogging device for concealed pipe drainage. It can crush the mud, sand, debris and filter media particles contained in the water during the drainage process through the crushing component, reduce their particle size, increase their discharge speed, greatly reduce the frequency of pipe blockage, eliminate the need for a lot of manpower, material resources and financial resources for cleaning operations, and greatly extend the service life of the pipe.

[0005] To solve the above-mentioned technical problems, this utility model provides a novel anti-clogging device for filter media in concealed pipe drainage. The anti-clogging device includes at least one unit and comprises a crushing component. The crushing component includes a support frame installed inside the drainage pipe, on which a crushing blade is rotatably mounted. The crushing blade rotates under the impact of water flow. This utility model utilizes the impact force of the water pressure within the drainage pipe to rotate the crushing blade, thereby crushing and guiding the silt, debris, and filter media particles in the wastewater out of the drain. This significantly improves drainage efficiency, reduces the frequency of drainage pipe blockage, and enhances the drainage capacity and service life of the drainage pipe.

[0006] It also includes a slag discharge pipe assembly, with at least one slag discharge pipe assembly. Each slag discharge pipe assembly includes two discharge pipes connected to the drainage pipe. The two discharge pipes in each slag discharge pipe assembly are located on both sides of the crushing component that is adapted to it. This utility model can realize the discharge of blocked impurities through the discharge pipes, further improving the sewage discharge capacity of the drainage pipe.

[0007] The drain pipe is tilted downwards, and the inlet is close to the side of the corresponding crushing blade or support frame. This is to facilitate the efficient discharge of debris remaining on the crushing components.

[0008] The other end of each discharge pipe is connected to the inlet of a sludge pump. The sludge pump can generate suction through the discharge pipe, which makes it easier and less labor-intensive to remove and clean the impurities adhering to the crushing components. This is more efficient and convenient, and improves the crushing efficiency of the crushing components.

[0009] The shredder blades are mounted on the support frame and rotated via bearings and a shaft.

[0010] Control valves are installed at both ends of the drain pipe and the anti-clogging device. When the shredding component needs cleaning, the control valves can be closed, and then the sludge pumps on the side of the shredding blades can be started to efficiently absorb and clean the debris remaining on the shredding blades. Then, the sludge pumps on the side closer to the support frame can be started to efficiently absorb and clean the debris remaining on the support frame side. There is no need to dig up the pipe or dig up the ground, which greatly improves the maintenance efficiency of the drain pipe, reduces the frequency of clogging, and extends the service life of the drain pipe.

[0011] The diameter of the inlet end of the drain pipe along the direction of water flow is smaller than the diameter of the other end. This design, where the diameter of the inlet end of the drain pipe is smaller than the diameter of the other end, enhances the impact force of the water flow on the crushing blades while reducing unnecessary energy loss.

[0012] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0013] 1. Effectively prevents clogging: This utility model can use the rotating shredder blade under the impact of water flow to crush larger debris and clumps of filter media in the water, preventing them from depositing in the pipe and forming clogging. This solves the problem of easy clogging in traditional underground drainage systems and ensures smooth drainage.

[0014] 2. Effectively prevents clogging: This utility model can use the rotating shredder blade under the impact of water flow to crush larger debris and clumps of filter media in the water, preventing them from depositing in the pipe and forming clogging. This solves the problem of easy clogging in traditional underground drainage systems and ensures smooth drainage.

[0015] 3. Reduced dredging costs: This utility model can use a sludge discharge pipe assembly in conjunction with a sewage pump to promptly extract the crushed sludge, completing the dredging without the need for pipe excavation, greatly reducing the difficulty and cost of dredging, and solving the problem of difficult dredging after blockage in traditional systems.

[0016] 4. Energy saving: This utility model can ensure smooth pipe flow through anti-clogging function, reduce drainage pressure and lower the energy consumption of drainage system; at the same time, the design of the inlet diameter of the drain pipe being smaller than that of the other end enhances the impact force of water flow on the crushing blade while reducing unnecessary energy loss, thus solving the problem of increased energy consumption caused by clogging in traditional systems.

[0017] Reduce environmental pollution: Timely removal of sludge prevents it from lingering in pipes, breeding bacteria, and producing odors, thus protecting the surrounding environment and solving the problem of sludge pollution. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0024] like Figure 1-4As shown: This embodiment provides a novel anti-clogging device for filter media in concealed pipe drainage. At least one anti-clogging device is provided, including a crushing component 110. The crushing component 110 includes a support frame 111 installed inside the drainage pipe 100, made of PVC-U material, with specifications of DN200-DN500, manufactured by Hebei Liansu Pipeline Technology Co., Ltd. The support frame 111 is made of 304 stainless steel, custom-manufactured by Wuxi Stainless Steel Products Factory. Its structure is a cross-shaped design to ensure stability under water flow impact. A crushing blade 112 is rotatably mounted on the support frame 111. Made of wear-resistant high manganese steel (ZGMn13), produced by Shandong Wear-Resistant Materials Co., Ltd., it has good impact resistance and wear resistance. Rotatingly installed inside the drain pipe 100, the crushing blade 112 can rotate under the impact of water flow. This utility model can achieve the crushing and guiding of mud, sand, debris, and filter media particles in wastewater under the impact force of the water pressure in the drain pipe 100, greatly improving the sewage discharge efficiency, reducing the frequency of blockage of the drain pipe 100, and improving the sewage discharge capacity and service life of the drain pipe 100.

[0025] According to one embodiment of the present invention, such as Figure 1-4 As shown, it also includes a slag discharge pipe assembly 120. There is at least one slag discharge pipe assembly 120. Each slag discharge pipe assembly 120 includes two discharge pipes 121 connected to the drainage pipe 100. They are made of PE material, with specifications of DN80-DN150, and are produced by Zhejiang Weixing New Building Materials Co., Ltd. The angle between them and the drainage pipe 100 is 30°-45° to facilitate the discharge of sludge. The two discharge pipes 121 in each slag discharge pipe assembly 120 are located on both sides of the crushing component 110 that is adapted to them. This utility model can realize the discharge of blocked impurities through the discharge pipes 121, further improving the sewage discharge capacity of the drainage pipe 100.

[0026] According to another embodiment of the present invention, such as Figure 1 and Figure 2 As shown, the discharge pipe 121 is inclined downwards, and the inlet is close to the side of the corresponding crushing blade 112 or support frame 111. This is to facilitate the efficient discharge of debris remaining on the crushing assembly 110.

[0027] According to another embodiment of the present invention, such as Figure 1 and Figure 3As shown, the other end of each of the 121 discharge pipes is connected to the inlet of a sewage pump. The pump is a self-priming sewage pump, model ZW80-80-15, with a power of 1.5kW and a head of 15m. It is manufactured by Shanghai Liancheng Pump Industry Group Co., Ltd. It can effectively extract the crushed sludge. The sewage pump can generate suction through the sewage pipe, which makes it easier and more labor-saving to suck out the impurities adhering to the crushing component 110 for cleaning. This is more efficient and convenient, and improves the crushing efficiency of the crushing component 110.

[0028] According to another embodiment of the present invention, such as Figure 1 and Figure 4 As shown, the crushing blade 112 is rotatably mounted on the support frame 111 via bearings and a rotating shaft 113. The bearings are deep groove ball bearings, model 6205, manufactured by Harbin Bearing Group Co., Ltd., to ensure that the crushing blade 112 rotates flexibly. The rotating shaft 113 is made of No. 45 steel and manufactured by Shanghai Baosteel Group. The surface is chrome-plated to improve wear resistance and rust prevention.

[0029] Control valves, specifically gate valves (model Z41X-16) manufactured by Tianjin Tanggu Valve Co., Ltd., are installed on both ends of the drain pipe 100 at the anti-clogging device. These valves control the opening and closing of the drain pipe 100, facilitating equipment maintenance. When the crushing component 110 needs cleaning, the control valves can be closed, and the sludge pumps on the side of the crushing blade 112 can be activated to efficiently absorb and clean the debris remaining on the crushing blade 112. Then, the sludge pumps on the side closer to the support frame 111 can be activated to efficiently absorb and clean the debris remaining on the support frame 111. This eliminates the need to dig up the pipe or excavate the ground, greatly improving the maintenance efficiency of the drain pipe 100, reducing the frequency of clogging, extending the service life of the drain pipe 100, and timely removal of sludge. It also prevents sludge from accumulating in the pipe for a long time, thus avoiding bacterial growth and odor, protecting the surrounding environment, and solving the problem of sludge pollution.

[0030] The diameter of the inlet end of the drain pipe 100 along the water flow direction is smaller than the diameter of the other end. The drain pipe 100 includes a small diameter end, a crushing component 110 mounting end welded to the small diameter end, and a large diameter end welded to the other end of the crushing component 110 mounting section. This design facilitates the enhancement of the impact force of the water flow on the crushing blade 112 while reducing unnecessary energy loss.

[0031] How to use this utility model:

[0032] First, it needs to be clarified that the anti-clogging device involved in this utility model is mainly used for anti-clogging operations during the sewage discharge process. This utility model will be described in detail using the working principle and usage method of the anti-clogging device for 100 drainage pipes during the drainage process as an example. The working principle is as follows:

[0033] This device achieves its anti-clogging function through the synergistic action of the crushing component 110 and the slag discharge pipe assembly 120. The specific working principle is as follows:

[0034] When water flows into the drain pipe 100, the water flow speed gradually decreases because the diameter of the inlet end is smaller than that of the outlet end. At the same time, the water flow impacts the crushing blade 112, causing it to rotate around the rotating shaft 113.

[0035] The rotating shredder blade 112 crushes larger debris and agglomerated filter media in the water into fine particles, preventing large particles from directly clogging the pipes.

[0036] The crushed particles and some silt move downstream of the drainage pipe 100 under the action of water flow, and some of them enter the discharge pipe 121 under the influence of gravity and water flow disturbance.

[0037] The control valves located at both ends of the anti-clogging device can be closed as needed. Then, the sludge pump generates negative pressure through the discharge pipe 121 to promptly extract the sludge remaining on both sides of the crushing component 110 that has entered the discharge pipe 121 and transport it to the designated treatment area.

[0038] The usage method is as follows:

[0039] Installation: Select an appropriate anti-clogging device according to the diameter and flow rate of the drain pipe 100, fix the support frame 111 inside the drain pipe 100, and ensure that the crushing blade 112 can rotate freely; connect the discharge pipe 121 to the drain pipes 100 on both sides of the crushing assembly 110, and ensure that the discharge pipe 121 is tilted downward; connect the other end of the discharge pipe 121 to the sewage pump, and install control valves at both ends of the drain pipe 100.

[0040] Start-up: Open the control valves at both ends of the drain pipe 100 to allow water to flow into the drain pipe 100. The water flow impacts the crushing blade 112, causing it to rotate.

[0041] Operation: During the drainage process, the crushing blade 112 continuously crushes debris in the water, and the sludge is pumped out by the sewage pump through the discharge pipe 121; the operation status of the sewage pump and the sludge collection are checked regularly, and the collected sludge is cleaned up in a timely manner.

[0042] Maintenance: When maintenance, replacement of parts, or periodic cleaning is required, close the control valves at both ends of the drain pipe 100 to stop the water flow, turn on the sludge pump, and continue until the impurities at both ends of the crushing component 110 are cleaned before resuming operation of the device.

[0043] This invention can use the crushing component 110 to crush the mud, sand, debris, and filter media particles contained in the water during the drainage process, reduce their particle size, increase their discharge speed, greatly reduce the frequency of pipe blockage, eliminate the need for a lot of manpower, material resources, and financial resources for cleaning operations, and greatly extend the service life of the pipes.

[0044] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0045] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
