Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and more specifically, to a prefabricated integrated water plant equipment. Background Technology

[0002] As an important development direction of modern water treatment engineering technology, prefabricated integrated water plant equipment provides a solution with small footprint, fast construction and stable operation for urban water supply, rural drinking water safety and decentralized water treatment by highly integrating and modularizing multiple treatment units of traditional water plants. Its core process links include multiple steps such as coagulation reaction, sedimentation separation, deep filtration and disinfection. Filtration treatment, as a key process for removing suspended solids, colloidal particles and some microorganisms in water, directly affects whether the quality of the effluent can meet the drinking water hygiene standards or discharge standards.

[0003] In existing prefabricated integrated water treatment equipment, raw water enters the filtration unit through the inlet pipe during filtration. After suspended solids and impurities are trapped by the filter bags, the clean water is discharged through the outlet pipe, completing the purification process. However, in actual operation, when the inlet flow rate is large or the water flow velocity is fast, a large water pressure can easily form at the end of the inlet pipe. This local high pressure can have several adverse effects on the filtration system: First, excessive water pressure can cause strong impacts on the filter bags, leading to fatigue damage or even rupture of the filter bag material, reducing filtration accuracy and affecting the quality of the effluent. Second, high-pressure water flow can disrupt the hydraulic balance within the filtration unit, causing excessive local load on the filter bags, accelerating clogging, reducing filtration efficiency, and shortening the service life of the filter bags. Third, pressure fluctuations can also cause pipeline vibration and seal failure, increasing the risk of equipment failure and affecting the reliability and effectiveness of the prefabricated integrated water treatment equipment. Utility Model Content

[0004] (a) Technical problems to be solved In view of the problems existing in the prior art, this utility model provides a prefabricated integrated water plant equipment to solve the technical problems mentioned in the background art.

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: A prefabricated integrated water plant equipment includes a filter pipe with an inlet pipe on one side wall and an outlet pipe on the other side wall. A filter bag is installed inside the filter pipe, and the lower end face of the filter bag is connected to the outlet pipe. A pressure relief pipe is connected through the filter pipe. The equipment also includes a pressure relief mechanism, which includes a connecting pipe connected to the pressure relief pipe. A threaded rod is threadedly connected inside the connecting pipe. A sealing plate is installed inside the connecting pipe, and a pressure relief port is opened on the side wall of the connecting pipe.

[0006] Preferably, the upper end face of the threaded rod is provided with a first fixing tube, and the surface of the first fixing tube is provided with multiple sets of first insertion holes. The setting of the first fixing tube and multiple sets of first insertion holes provides a position locking function for the pressure relief mechanism.

[0007] Preferably, a sliding tube is slidably connected inside the threaded rod, and a sealing disc is connected to one end of the sliding tube. The sealing disc and the sealing plate are in sealing contact. The sliding fit structure between the sliding tube and the threaded rod allows the sealing disc to move freely along the axial direction under water pressure, realizing the dynamic switching of the sealing state between the sealing disc and the sealing plate.

[0008] Preferably, the other end of the slide tube is connected to a second fixed tube. The surface of the second fixed tube is provided with a second insertion hole corresponding to the first insertion hole. The first insertion hole and the second insertion hole are provided with two sets of pins. The corresponding design of the first insertion hole and the second insertion hole, together with the locking effect of the two sets of pins, realizes the rigid connection between the first fixed tube and the second fixed tube, thereby locking the entire sliding assembly in a fixed position.

[0009] Preferably, a top spring is fitted on the surface of the slide tube. One end of the top spring is fixedly connected to the side wall of the threaded rod, and the other end is fixedly connected to the side wall of the sealing disc. As the core elastic element, the top spring establishes an adjustable preload between the threaded rod and the sealing disc. On the one hand, it provides a continuous and stable clamping force between the sealing disc and the sealing plate to ensure reliable sealing under normal working conditions. On the other hand, it sets a pressure threshold for pressure relief activation. When the water pressure exceeds the spring force of the top spring, the pressure relief action is triggered. At the same time, the top spring also provides a reset function for the sealing disc to ensure that the system quickly restores the sealing state after pressure relief.

[0010] Preferably, a sampling tube is slidably connected inside the slide tube, and a compression spring is sleeved on one end of the sampling tube. One end of the compression spring is fixedly connected to the sampling tube, and the other end is fixedly connected to the side wall of the second fixed tube. The sliding fit structure between the sampling tube and the slide tube, combined with the elastic recovery effect of the compression spring, constructs a simple and efficient manual sampling mechanism.

[0011] Preferably, the other end of the sampling tube is connected to a sealing block, the side wall of the sealing block is in close contact with the sealing plate, and a sampling hole is provided on the sealing block. The sampling hole is connected to the sampling tube. The close contact between the sealing block and the sealing plate completely blocks the sampling channel during normal operation, ensuring the sealing integrity of the pressure relief system. When the sampling tube is pressed to separate the sealing block from the sealing plate, the sampling hole is connected to the water flow channel, and the water sample in the filter tube can smoothly enter the sampling tube and flow out from the other end for testing.

[0012] (III) Beneficial Effects Compared with existing technologies, this utility model provides a prefabricated integrated water treatment plant equipment with the following advantages: This utility model designs a pressure relief mechanism based on the spring pressure balance principle, solving the problems of system instability and equipment damage caused by inlet water pressure fluctuations during the filtration process in traditional water treatment equipment. Under normal filtration conditions, when the water pressure inside the filter pipe is within a reasonable range, the top spring maintains a preset clamping force, ensuring a tight seal between the sealing disc and the sealing plate, forming a reliable seal. The pressure relief channel is completely closed, and all incoming water is purified through the filter bag, ensuring... The filtration efficiency and the stability of the effluent water quality are ensured by the following: When the influent flow rate suddenly increases or the water flow velocity accelerates, causing the pressure inside the filter tube to rise, the high-pressure water flow acts on the surface of the sealing disc through the pressure relief pipe, generating an axial thrust on the sealing disc. As the pressure continues to increase, when the thrust exceeds the preload of the top spring, the sealing disc moves backward under the action of water pressure, overcoming the spring resistance, and releasing the sealing contact with the sealing plate. The pressure relief channel then opens, and the high-pressure water flow inside the filter tube enters the connecting pipe through the pressure relief pipe, and is then quickly discharged through the pressure relief port on the side wall of the connecting pipe, effectively releasing the excess pressure energy accumulated in the system.

[0013] Once the pressure drops to a safe range, the elastic restoring force of the top spring immediately pushes the sealing disc and slide tube back to their original positions. The sealing disc then re-seales with the sealing plate, automatically closing the pressure relief channel and restoring the system to normal filtration. The entire pressure relief process requires no manual intervention or external energy. This pressure relief function effectively protects the filter bags from the continuous impact of high-pressure water flow, avoiding fatigue damage and rupture risks caused by mechanical stress concentration in the filter bag material. This extends the service life of the filter bags, reduces the frequency of spare parts replacement and operating costs. At the same time, the pressure relief mechanism effectively eliminates pipeline vibration and water hammer effects caused by pressure fluctuations, protecting the integrity of pipeline connections, flange seals, and equipment housing structures, and reducing equipment failure rates and maintenance workload.

[0019] Please see Figures 1-6A prefabricated integrated water plant equipment includes a filter pipe 11, with an inlet pipe 12 on one side wall and an outlet pipe 13 on the other side wall. A filter bag 14 is installed inside the filter pipe 11, with its lower end connected to the outlet pipe 13. A pressure relief pipe 15 is connected through the filter pipe 11. The equipment also includes a pressure relief mechanism, comprising a connecting pipe 21 connected to the pressure relief pipe 15. A threaded rod 22 is threaded into the connecting pipe 21. A sealing plate 23 is installed inside the connecting pipe 21. A pressure relief port 24 is opened on the side wall of the connecting pipe 21. A first fixing pipe 25 is provided on the upper end face of the threaded rod 22. Multiple sets of first insertion holes 26 are opened on the surface of the first fixing pipe 25. A sliding tube 27 is slidably connected inside the threaded rod 22. One end of the sliding tube 27 is connected to a sealing disc 28, which seals against the sealing plate 23. The other end of tube 27 is connected to a second fixed tube 29. The surface of the second fixed tube 29 is provided with a second insertion hole 210 corresponding to the first insertion hole 26. Two sets of pins 211 are provided in the first insertion hole 26 and the second insertion hole 210. A top spring 212 is sleeved on the surface of the sliding tube 27. One end of the top spring 212 is fixedly connected to the side wall of the threaded rod 22, and the other end is fixedly connected to the side wall of the sealing plate 28. A sampling tube 213 is slidably connected inside the sliding tube 27. A compression spring 214 is sleeved on one end of the sampling tube 213. One end of the compression spring 214 is fixedly connected to the sampling tube 213, and the other end is fixedly connected to the side wall of the second fixed tube 29. A sealing block 215 is connected to the other end of the sampling tube 213. The side wall of the sealing block 215 is tightly abutted against the sealing plate 28. A sampling hole 216 is provided on the sealing block 215, and the sampling hole 216 communicates with the sampling tube 213.

[0020] Water to be filtered flows into the filter pipe 11 through the inlet pipe 12, then through the filter bag 14, and the filtered clean water flows out through the outlet pipe 13. When pressure relief is not required during filtration, the pin 211 is inserted into the first socket 26 and the second socket 210 to fix the position of the second fixing pipe 29 and the first fixing pipe 25. The fixing of the second fixing pipe 29 fixes the sliding pipe 27 and the sealing plate 28, thus ensuring that the sealing plate 28 and the sealing plate 23 always maintain a sealed contact, and the pressure relief mechanism is rendered ineffective. When pressure relief is required during filtration, the pin 211 is pulled out of the first socket 26. 6. Inside the second insertion hole 210, the slide tube 27 can slide along the threaded tube. When the pressure inside the filter tube 11 is high, the water squeezes the sealing disc 28 through the pressure relief pipe 15. The sealing disc 28 is pressured to overcome the elastic force of the top spring 212 and releases the sealing contact with the sealing plate 23. The sealing disc 28 pushes the slide tube 27 and the second fixed pipe 29 to move synchronously. The water flows into the connecting pipe 21 and is discharged through the pressure relief port 24. After the pressure is removed, the top spring 212 rebounds and drives the sealing disc 28 and the slide tube 27 to reset. The sealing disc 28 seals against the sealing plate 23 again, achieving the purpose of pressure relief. When water needs to be sampled and tested in the filter tube 11, the operator can manually press the sampling tube 213. The compression spring 214 is compressed, and the sampling tube 213 slides along the inner wall of the slide tube 27, releasing the sealing contact between the end sealing block 215 and the sealing plate 28. The water sample flows into the sampling tube 213 through the sampling hole 216 on the surface of the sealing block 215, and finally flows out through the other end of the sampling tube 213, achieving the sampling purpose. After the sampling is completed, the operator stops pressing, and the compression spring 214 rebounds, driving the sampling tube 213 and the sealing block 215 to reset, and the sealing contact between the sealing block 215 and the sealing plate 28 is restored. Rotating the threaded rod 22 can adjust the pressure of the top spring 212 on the sealing plate 28, thereby adjusting the pressure required to release the seal between the sealing plate 28 and the sealing plate 23.
