Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a PPH filter. Background Technology

[0002] Most filtration equipment uses filter cartridges to filter water flow. Common filter cartridges include alumina filter cartridges, and the membrane housing that holds the filter cartridge is usually made of metal. However, sewage is generally highly corrosive, and these filter cartridges and membrane housings are prone to severe corrosion after long-term use, resulting in a limited service life and inconvenience.

[0003] Furthermore, impurities in the water are easily retained inside the filter element. After the filter element is used, due to the small pores on the filter element, some of the water that has passed through the filter element is easily retained on the filter element. In addition, impurities and bacteria after the filter element is filtered adhere to the filter element, which can easily lead to the growth of bacteria and microorganisms in the humid environment, affecting the filtration effect and service life of the filter element, which is quite inconvenient.

[0004] Wastewater is usually transported into filtration equipment through pipelines. Some filtration equipment has a complex internal pipeline network. In order to save space, the pipelines in the equipment are designed with small spacing between them. As a result, when the user performs maintenance on the filtration equipment, the user can only perform maintenance on the pipelines in the network from the outside. The working area is limited, and the pipelines in the inner part of the network are inconvenient for the user to maintain. Summary of the Invention

[0005] The purpose of this invention is to provide a PPH filter to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] PPH filters include:

[0008] The system comprises a housing, a cleaning mechanism for testing filter media, multiple connecting mechanisms, and a separation mechanism for separating and disassembling the cleaning mechanism. The housing has an opening at the bottom and one side. Door panels are rotatably connected to both sides of the opening on one side of the housing. The cleaning mechanism is located inside the housing and includes a membrane module. The membrane module is equipped with a self-priming pump. The self-priming pump is equipped with an air tank and two backwash tanks. The membrane module, the self-priming pump, the air tank, and the two backwash tanks are all interconnected through connecting pipes. Multiple automatic valves are installed on the connecting pipes. The multiple connecting mechanisms are detachably connected to the multiple connecting pipes. The separation mechanism is located below the housing.

[0009] Furthermore, the membrane assembly includes:

[0010] The device comprises a cylinder, two fixed plates, two connecting covers, and multiple ceramic membrane filter media. Multiple backflush pipes are fixedly connected to the outer wall of the cylinder. The two fixed plates are detachably connected to the top and bottom ends of the cylinder on their adjacent sides. Each of the two fixed plates has two slots on its adjacent side. The two connecting covers are detachably connected to the opposite side of the two fixed plates on their adjacent sides. Each of the opposite ends of the two connecting covers has a forward flush pipe fixedly connected to it. Each of the multiple ceramic membrane filter media has multiple water guide holes at one end. Both ends of any ceramic membrane filter media are movably snapped into the two parallel slots on the two fixed plates.

[0011] Furthermore, the connecting mechanism includes:

[0012] Multiple columns, multiple support frames, and multiple pipe clamps are provided. The bottom ends of the multiple columns are fixedly connected to the top surface of the separation mechanism. The multiple support frames are located between two adjacent connecting pipes. The two ends of the multiple pipe clamps are detachably connected to the adjacent columns or support frames.

[0013] Furthermore, the separation mechanism includes:

[0014] The system comprises two base plates, two sliders, and a sliding frame. The two base plates are located at the bottom of the housing. The bottom ends of the multiple columns are fixedly connected to the top surfaces of the adjacent base plates. The membrane module, the self-priming pump, and the gas storage tank are all fixedly connected to the top surfaces of the adjacent base plates via brackets. The top ends of the two sliders are fixedly connected to the adjacent ends of the two base plates respectively. The sliding frame is located below the two base plates. The two sliders are slidably engaged inside the sliding frame. An adjusting screw is rotatably connected between the two ends inside the sliding frame. A screw engagement hole is provided on the adjacent side of each of the two sliders. The adjusting screw is a positive and negative thread screw, and the inner sidewalls of the two screw engagement holes are respectively engaged with the two sections of thread on the adjusting screw.

[0015] Furthermore, the shell is fixedly connected to two opposite sides with a frame, and the two base plates are fixedly connected to a J-shaped plate at opposite ends, with one end of each J-shaped plate movably engaged inside the two frames.

[0016] Furthermore, a motor box is fixedly connected to one end of the slide frame, and a drive motor is installed inside the motor box. The motor shaft of the drive motor passes through one end of the slide frame and is fixedly connected to one end of the adjusting screw.

[0017] Furthermore, each of the four corners of the bottom surface of any base plate is fixedly connected to a support arm, and each support arm is rotatably connected to a load-bearing wheel at its bottom end.

[0018] Furthermore, connecting plates are fixedly connected to the top surfaces of the two base plates at opposite ends, and slots are provided at one end of each connecting plate. Two plates are fixedly connected to the inner wall of the housing, and locking rods are fixedly connected to both ends of the opposite sides of the two plates. Each locking rod is movably engaged in the adjacent slot.

[0019] Furthermore, the top surface of the housing is fixedly connected with multiple lifting rings.

[0020] Furthermore, a U-shaped frame is provided between one end of the two plates, and a sliding cylinder is fixedly connected to one end of each arm of the U-shaped frame. A sliding rod is fixedly connected to one end of each of the two plates, and the two sliding rods are respectively slidably sleeved inside the two sliding cylinders. A rebound spring is provided inside each of the two sliding cylinders.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. By connecting pipes to form a pipeline system and installing automatic valves at the pipe connections, the water flow can be filtered by the filter media inside the membrane module. Then, gas from the gas storage tank is used to perform forward and backwashing on the filter media. The gas in the gas storage tank, combined with the water flow in the backwash tank, forms a gas-liquid mixture that further cleans the filter media. This process improves the cleaning effect of the filter media after filtration. Furthermore, the gas forward and backwashing also dries the filter media, reducing conditions for microbial and bacterial growth and extending its lifespan. The use of ceramic membrane elements and PPH materials in the membrane module extends the service life of the filter element and membrane housing. The high mechanical strength and high pressure resistance of the ceramic membrane element allow it to withstand long-term forward and backwashing treatments, further extending its lifespan.

[0023] 2. By pre-removing the bolts on some of the connecting pipe flanges, the connecting pipes loaded on the two base plates are disconnected. Then, the drive motor is started to drive the adjusting screw to rotate, causing the adjusting screw to move the two base plates away from each other. This causes the two J-type clamping plates to disengage from the adjacent clamping frames and the clamping rods to disengage from the adjacent clamping slots, thus separating the two base plates. This separates the equipment and connecting pipes loaded on the two base plates, allowing users to inspect and maintain the equipment and connecting pipes loaded on the base plates from between the two base plates. This increases the operating surface for users and facilitates maintenance.

[0024] 3. During maintenance, the housing can be lifted using hoisting equipment and lifting rings. After maintenance, start the drive motor to rotate the adjusting screw, which will cause the adjusting screw to move the two base plates towards each other through the two sliders. After the two base plates have moved to a suitable distance, lower the housing. The user can manually hold the U-shaped frame to adjust the position of the housing, making it easy for the housing to be accurately positioned. After the housing has been lowered to the appropriate position, the drive motor can be started again to make the two base plates continue to move towards each other, so that the J-shaped clamping plate can be inserted into the adjacent clamping frame and the clamping rod can be inserted into the adjacent clamping slot. When the user holds the U-shaped frame to adjust the position of the housing, the U-shaped frame can be rotated and moved laterally to prevent the U-shaped frame from contacting the equipment or connecting pipes loaded on the base plate.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figures 1-7 In this embodiment of the invention, the PPH filter includes:

[0035] The system comprises a housing 100, a cleaning mechanism 200 for testing filter media, multiple connecting mechanisms 300, and a separation mechanism 400 for separating and disassembling the cleaning mechanism 200. The housing 100 has an opening at the bottom and one side. Door panels 110 are rotatably connected to both sides of the opening on one side of the housing 100. The cleaning mechanism 200 is located inside the housing 100 and includes a membrane module 210. The membrane module 210 is equipped with a self-priming pump 220, an air tank 230, and two backwash tanks 240. The membrane module 210, the self-priming pump 220, the air tank 230, and the two backwash tanks 240 are all interconnected through connecting pipes. Multiple automatic valves are provided on the connecting pipes. The multiple connecting mechanisms 300 are detachably connected to the multiple connecting pipes. The separation mechanism 400 is located below the housing 100.

[0036] Specifically, the connecting pipes can be interconnected to form a complex piping system. These pipes are connected via flanges and can be disassembled. During use, automatic valves are installed at each connection point to control the flow between the pipes. Users can freely control the connection status (open or closed) using these valves. Pipelines can be connected within the piping system to supply and discharge water. After passing through the piping system and the self-priming pump 220, the water enters the membrane module 210. The water is naturally filtered by the filter media within the membrane module 210 and flows through the piping system into the two backwash tanks 240. Users can then activate the air storage tank 230 in conjunction with the piping system, allowing gas from the air storage tank 230 to enter the backwash tanks 240 through the piping system. Excess water can be directly discharged from the backwash tanks 240, thus facilitating the operation of the backwash tanks 240. The gas inside the internal water-mixing gas storage tank 230 backflushes the filter media inside the membrane module 210, thereby cleaning the filter media. Alternatively, the gas storage tank 230 can be activated through the pipeline system to directly backflush the filter media inside the membrane module 210 with gas. It can also be activated to forward flush the filter media inside the membrane module 210 with gas through the pipeline system, blowing air to dry the filter media. Thus, by using gas or a gas-liquid mixture to perform forward and backflushing treatment on the filter media inside the membrane module 210, the filter media inside the membrane module 210 can be cleaned. The gas can also be blown onto the filter media to blow out impurities and dry the filter media at the same time. Therefore, the filter media can be automatically cleaned and dried after filtration. The gas storage tank 230, self-priming pump 220, etc. are existing technologies and will not be described in detail here.

[0037] Example 1

[0038] like Figure 4 As shown, in this embodiment, the membrane module 210 includes:

[0039] The cylinder 211 consists of two fixing plates 212, two connecting covers 213, and multiple ceramic membrane filter media 214. Multiple backflush pipes 2111 are fixedly connected to the outer wall of the cylinder 211. The two fixing plates 212 are detachably connected to the top and bottom ends of the cylinder 211 on adjacent sides. Two bayonets 2121 are opened on adjacent sides of the two fixing plates 212. The two connecting covers 213 are detachably connected to the opposite side of the two fixing plates 212 on adjacent sides. A forward flush pipe 2131 is fixedly connected to the opposite end of the two connecting covers 213. Multiple water guide holes are opened at one end of each of the multiple ceramic membrane filter media 214. Both ends of any ceramic membrane filter media 214 are movably snapped into the two parallel bayonets 2121 on the two fixing plates 212.

[0040] In this embodiment, the connecting pipe can be connected to the backflush pipe 2111 and the forward flush pipe 2131. In use, the ceramic membrane filter material 214 is snapped between the slots 2121 of the two fixing plates 212. The ceramic membrane filter material 214 is a porous ceramic membrane filter element. When water needs filtration, the water flows through the forward flush pipe 2131 into the interior of multiple ceramic membrane filter materials 214 and exits from the multiple backflush pipes 2111, thereby filtering the water flow. When gas or a gas-liquid mixture passes through any of the forward flush pipes 2131 into the interior of the ceramic membrane filter material 214 and exits from the multiple backflush pipes 2111, the multiple ceramic membrane filter materials 214 can be forward flushed. When a gas or gas-liquid mixture passes through the interior of the ceramic membrane filter media 214 from multiple backflush pipes 2111 and is discharged from any forward flush pipe 2131, the gas or gas-liquid mixture can perform backflush treatment on the multiple ceramic membrane filter media 214. The cylinder 211, the fixing plate 212, and the two connecting covers 213 are all made of high-strength PPH material. Because PPH has excellent corrosion resistance, it can enhance the corrosion resistance of the membrane module 210. In addition, the cylinder 211, the fixing plate 212, and the connecting covers 213 are relatively thick and have strong pressure resistance. The ceramic membrane filter element has the advantages of high mechanical strength and high pressure resistance, which allows it to withstand long-term backflush and forward flushing.

[0041] like Figure 3 and Figure 5 As shown, in this embodiment, the connecting mechanism 300 includes:

[0042] Multiple columns 310, multiple brackets 320, and multiple pipe clamps 301 are provided. The bottom ends of the multiple columns 310 are fixedly connected to the top surface of the separation mechanism 400. The multiple brackets 320 are located between two adjacent connecting pipes. The two ends of the multiple pipe clamps 301 are detachably connected to the adjacent columns 310 or brackets 320.

[0043] In specific implementation, the connecting pipe inside the housing 100 near the bottom of the housing 100 can be supported by installing a column 310 near the connecting pipe, then fitting a pipe clamp 301 onto the connecting pipe, and making a hole in the column 310. The column 310 and the pipe clamp 301 are connected together using bolts or other connectors, thereby supporting the pipeline system formed by the connecting pipe. A support frame 320 is set between the connecting pipe near the top of the housing 100 and the connecting pipe near the bottom of the housing 100 inside the housing 100, and the connecting pipe is fixed to the support frame 320 using the pipe clamp 301. This allows the connecting pipe at the lower part of the housing 100 to support the connecting pipe at the upper part through the support frame 320, while the connecting pipe at the lower part can be supported by the separation mechanism 400 through the column 310.

[0044] like Figures 6-7 As shown, in this embodiment, the separation mechanism 400 includes:

[0045] The system comprises two base plates 410, two sliders 420, and a sliding frame 430. Both base plates 410 are located at the bottom of the housing 100. Multiple columns 310 are fixedly connected to the top surfaces of adjacent base plates 410 at their bottom ends. The membrane module 210, self-priming pump 220, and gas storage tank 230 are all fixedly connected to the top surfaces of adjacent base plates 410 via brackets. The top ends of the two sliders 420 are fixedly connected to adjacent ends of the two base plates 410. The sliding frame 430 is located below the two base plates 410. Both sliders 420 are slidably engaged inside the sliding frame 430. An adjusting screw 431 is rotatably connected between the two ends inside the sliding frame 430. Each of the two sliders 420 has a screw hole on an adjacent side. The adjusting screw 431 is a double-threaded screw, and the inner walls of the two screw holes are respectively engaged with two sections of thread on the adjusting screw 431. Frames 120 are fixedly connected to opposite sides of the housing 100. J-shaped clamping plates 411 are fixedly connected to opposite ends of the base plate 410, and one end of each of the two J-shaped clamping plates 411 is movably engaged inside the two clamping frames 120. A motor box 432 is fixedly connected to one end of the sliding frame 430, and a drive motor is installed inside the motor box 432. The motor shaft of the drive motor passes through one end of the sliding frame 430 and is fixedly connected to one end of the adjusting screw 431. Support arms are fixedly connected to the four corners of the bottom surface of any base plate 410, and a load-bearing wheel 412 is rotatably connected to the bottom end of each support arm. Connecting plates 460 are fixedly connected to opposite ends of the top surfaces of the two base plates 410, and a slot 461 is opened at one end of each of the two connecting plates 460. Two plates 450 are fixedly connected to the inner wall of the housing 100, and two clamping rods 451 are fixedly connected to both ends of the opposite side of the two plates 450. Each clamping rod 451 is movably engaged inside the adjacent slot 461.

[0046] In practical implementation, when the piping system consisting of connecting pipes is pre-laid out, the flanges at the connection points of the connecting pipes supported by the two base plates 410 are positioned close to the door plate 110. This facilitates the user's removal of the bolts on the flanges to disconnect the connecting pipes supported by the two base plates 410. The two base plates 410 are supported by multiple load-bearing wheels 412 and can move on the ground via the load-bearing wheels 412. When it is necessary to replace the connecting pipes or perform other maintenance work, the bolts on the flanges at some of the connecting pipe connections can be removed to disconnect some of the connecting pipes. The connection pipe is disconnected, thus completely separating the connecting pipe sections supported by the two base plates 410. The user can then start the drive motor to rotate the adjusting screw 431, causing the adjusting screw 431 to move the two sliders 420 in opposite directions, thereby separating the two base plates 410. The base plates 410 can also separate the connecting pipes, self-priming pump 220, air tank 230, membrane module 210, and other equipment mounted above them, and cause the ends of the two J-shaped clamping plates 411 to detach from the adjacent clamping frames 120. The user can then... The housing 100 can be detached from the two base plates 410, and the drive motor can be started to drive the two base plates 410 to continue moving away from each other, separating the equipment and connecting pipes loaded on the two base plates 410. This reduces the complexity of the connecting pipes loaded on a single base plate 410, and because the two base plates 410 are separated, the user can inspect the piping system from between the two base plates 410, increasing the user's working area and facilitating the maintenance of the piping system. After the maintenance is completed, the drive motor can be started. The machine brings the two base plates 410 closer together. After a certain gap is left between the two base plates 410, the housing 100 is installed in a suitable position. Then, the drive motor is started to drive the two base plates 410 to continue to move closer together until one end of the two J-shaped clamping plates 411 is inserted into the adjacent clamping frame 120 to fix the housing 100. At this time, the clamping rods 451 on the two plates 450 can be inserted into the adjacent clamping slots 461. The clamping rods 451 are inserted into the clamping slots 461 to make the connection between the housing 100 and the two base plates 410 more tight.

[0047] Example 2

[0048] Based on Embodiment 1, a U-shaped frame 440 is provided to facilitate the user's adjustment of the position of the housing 100.

[0049] like Figure 7 As shown, in this embodiment, a plurality of lifting rings 101 are fixedly connected to the top surface of the housing 100, a U-shaped frame 440 is provided between one end of the two plates 450, and a slide cylinder 441 is fixedly connected to one end of each arm of the U-shaped frame 440. A slide rod 452 is fixedly connected to one end of each of the two plates 450, and the two slide rods 452 are respectively slidably sleeved inside the two slide cylinders 441. A rebound spring 453 is provided inside each of the two slide cylinders 441.

[0050] In practice, users can use indoor hoisting equipment and lifting rings 101 to lift the housing 100. After maintenance, when lowering the housing 100, users can manually hold the U-shaped frame 440 to adjust the position of the housing 100, so that the housing 100 falls to a suitable position, making it easy for one end of the J-shaped clamping plate 411 to be inserted into the clamping frame 120, and for the clamping rod 451 on the plate 450 to be inserted into the adjacent clamping slot 461. When users manually hold the U-shaped frame 440, the U-shaped frame 440 can rotate around the two sliding cylinders 441, making it difficult for the U-shaped frame 440 to contact the connecting pipes and equipment loaded on the base plate 410. In addition, users can move the U-shaped frame 440 horizontally, so that the sliding rod 452 can slide inside the sliding cylinder 441 to adjust the position of the U-shaped frame 440, making it difficult for it to contact the connecting pipes and equipment loaded on the base plate 410.

[0051] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0052] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
