Description

Technical Field

[0001] The present invention relates to the technical field of filtration stations, and specifically to an energy storage type large flow backwashing filtration station. Background Art

[0002] A large flow backwashing filtration station is an efficient device used in industrial water treatment or fluid filtration systems. It is mainly used to handle large flow liquids (such as water, oil or other media) during continuous filtration, and at the same time, through an automatic backwashing function, the impurities attached to the surface of the filter media are removed to maintain the filtration efficiency and extend the service life of the equipment.

[0003] However, at present, the large flow backwashing filtration stations rely on an external high-pressure water source to drive the washing water flow during the backwashing process to achieve the backwashing effect of the filtration components, resulting in a significant increase in equipment energy consumption, and the washed sewage is directly discharged without being able to recycle the water source repeatedly, causing waste of water resources. Summary of the Invention

[0004] (1) Technical Problems to be Solved

[0005] In view of the deficiencies of the prior art, the present invention provides an energy storage type large flow backwashing filtration station, which has the advantages of being able to achieve the backwashing effect without relying on an external high-pressure water source, and being able to filter and recycle the discharged sewage repeatedly. It solves the problems of increased equipment energy consumption caused by the current method of using an external high-pressure water source to drive the washing water flow, direct discharge of the washed sewage without secondary recycling, and reduction of water resource waste.

[0006] (2) Technical Solutions

[0007] To achieve the above object, the present invention provides the following technical solution: An energy storage type large flow backwashing filtration station, comprising a tank body, a filtration component, a cleaning component, a sealing plate, a regulation component, a washing component and a gas supply component. The side of the tank body is sequentially provided with a water inlet valve port, a water outlet valve port, a return pipe and a sewage discharge valve port from top to bottom. The water inlet valve port is used to convey water source into the tank body, the water outlet valve port is used to discharge the filtered water source in the tank body, the return pipe is used to re-input the secondarily filtered water source into the tank body, and through cooperation with the washing component, it realizes the reverse washing operation of the filter cylinder, while the sewage discharge valve port is used to discharge sewage.

[0008] A filtration component is installed in the tank body. The filtration component is composed of a filter cylinder, an upper cover plate and a lower cover plate. The filter cylinder is installed between the upper cover plate and the lower cover plate. At the same time, the edges of the upper cover plate and the lower cover plate are fixed on the inner wall of the tank body. By fixing the edges on the inner wall of the tank body, an independent water storage space is formed between the side of the filter cylinder and the inner wall of the tank body to store the filtered water source. The water source is filtered by being input into the filter cylinder, so that the impurities stay in the filter cylinder, and the filtered water source flows into the water storage space.

[0009] An inlet water groove is formed on the upper cover plate, and an outlet water hole is formed on the lower cover plate. At the same time, the inlet valve port is located above the upper cover plate, and the outlet valve port is located at the bottom between the tank body and the filter cylinder. When the water source is input through the inlet valve port, the water source flows into the filter cylinder through the inlet water groove for filtration. When discharging impurities in the filter cylinder, in the state where the outlet water hole is unblocked, the sewage containing impurities is discharged into the space to be treated between the sealing plate and the partition plate.

[0010] A cleaning component for cleaning the dirt on the inner wall of the filter cylinder is installed in the filter cylinder. The cleaning component is used to scrape off the impurities attached to the filter cylinder, improving the filtration smoothness and efficiency of the filter cylinder.

[0011] Inside the tank body, and successively fixed from top to bottom at the bottom of the lower cover plate are a partition plate, a filter plate, and a diaphragm. One end of the return pipe communicates between the partition plate and the filter plate, and the other end of the return pipe communicates between the tank body and the filter cylinder. At the same time, the sewage discharge valve port communicates between the filter plate and the diaphragm. The return pipe is used to input the water source between the partition plate and the filter plate into the water storage space. At the same time, when the sewage containing impurities is input into the filtration space between the filter plate and the diaphragm, under the influence of the gravity of the sewage, the diaphragm generates a downward deformation phenomenon to store the sewage. When the diaphragm is under an upward thrust force, the sewage is filtered twice through the filter plate, and the filtered water source is re-input into the water storage space through the return pipe. At the same time, the diaphragm is reset, and the impurities and a small part of the unfiltered water source are left between the filter plate and the diaphragm. When the sewage discharge valve port is opened, the impurities are discharged outside the tank body through this part of the unfiltered water source.

[0012] A sealing plate for blocking the drainage of the outlet water hole is connected to the bottom of the filter component. The top of the sealing plate fits against the bottom of the lower cover plate to block the outlet water hole, so that the normal filtration function can be realized inside the filter cylinder. When the sealing plate is separated from the lower cover plate, the water source and impurities in the filter cylinder can be discharged through the outlet water hole.

[0013] An installation position is provided on the axis of the partition plate and the filter plate.

[0014] A regulating component is installed inside the tank body. The regulating component includes a ball valve movably connected in the installation position. A regulating part for controlling the rotation of the ball valve and the lifting of the sealing plate is fixed on the side of the ball valve. The regulating part is movably connected to the tank body. The installation position is circular and concave inside. The ball valve matches the inner diameter of the installation position. By controlling the ball valve to rotate clockwise and counterclockwise in the vertical direction through the regulating part, the communication and blocking between the space at the top of the partition plate and the space at the bottom of the filter plate are realized. At the same time, the regulating part also controls the sealing plate to change in height. When the sealing plate moves downward, the outlet water hole leaks, and at the same time, the ball valve interface communicates with the top of the partition plate and the bottom of the filter plate, so as to discharge the water source and impurities in the filter cylinder into the filtration space.

[0015] A flushing assembly is installed in the tank body, which includes an annular tube fixed on the inner wall of the tank body. One end of the return pipe is connected to the inside of the annular tube. At the same time, a plurality of spray pipes are equidistantly arranged on the annular tube. The water source after secondary filtration is input into the annular tube through the return pipe. The annular tube distributes the water source to each spray pipe. Under the action of continuous input of the water source, the spray pipe returns the secondary filtered water source to the filter cartridge by reverse flushing and washes away the impurities attached to the inner wall of the filter cartridge.

[0016] As a further improvement of the above scheme, the cleaning assembly consists of a rotating rod and a scraper. The side of the rotating rod is movably sleeved with a sleeve, and a sleeve rod is movably sleeved in the sleeve. One end of the sleeve rod is fixed on the scraper, and the scraper is attached to the inner side of the filter cartridge. At the same time, a driving motor is fixed on the tank body, and the output end of the driving motor is fixed on the rotating rod.

[0017] Through the above technical solution, the output end of the driving motor has a bidirectional rotation function. During operation, the output end drives the rotating rod to rotate, so that the scraper scrapes and cleans the inner wall of the filter cartridge, avoiding excessive adhesion of impurities to the inner wall of the filter cartridge and improving the smoothness of water filtration.

[0018] As a further improvement of the above solution, a tension spring is movably sleeved on the side of the sleeve rod, and both ends of the tension spring are fitted between the sleeve and the scraper. At the same time, both ends of the sleeve are threadedly connected with a positioning ring, which is fitted on the side of the rotating rod.

[0019] Through the above technical solution, the two ends of the tension spring abut against the force between the sleeve and the back of the scraper, so that the scraper can scrape and clean the inside of the filter cartridge with different diameters and improve the fit between the scraper and the inner wall of the filter cartridge.

[0020] As a further improvement of the above solution, a rotating knob 1 and a rotating knob 2 are respectively provided at both ends of the rotating rod, the rotating knob 1 is rotatably connected to the axis center line of the upper cover plate, and the rotating knob 2 is rotatably connected to the axis center line of the lower cover plate.

[0021] Through the above technical solution, the first and second turning knobs are rotatably connected to the axis center line of the corresponding cover plate, thereby improving the stability of the rotation of the rotating rod.

[0022] As a further improvement of the above scheme, a stabilizing sleeve rod is fixed at one end of the rotating rod, and a ring is provided on the axial line of the bottom of the sealing plate. The sealing plate and the ring are movably connected to the stabilizing sleeve rod. At the same time, a limit button is fixed at one end of the stabilizing sleeve rod, and the limit button is fitted to the bottom of the ring.

[0023] Through the above technical solution, when the height of the sealing plate changes, the ring and the sealing plate slide up and down on the side of the stabilizing sleeve rod at the same time, thereby improving the stability of the sealing plate's lifting and lowering. At the same time, the height of the sealing plate's descent is limited by the limit button installed at the bottom end of the stabilizing sleeve rod, thereby preventing the sealing plate from detaching from the stabilizing sleeve rod.

[0024] As a further improvement of the above solution, the adjustment control unit includes a connecting rod fixed at both ends of the ball valve, the connecting rod passes through the installation position and is rotatably connected to the side of the tank body, and an adjustment button is fixed at one end of the connecting rod.

[0025] Through the above technical solution, by turning the adjusting knob, the ball valve is rotated vertically, so that the interface of the ball valve connects the space to be treated and the filtering space, so that sewage enters the filtering space from the space to be treated and waits for secondary filtration recovery and backwashing operations.

[0026] As a further improvement of the above solution, the adjustment control unit also includes a transmission bar movably connected to the connecting rod, a connecting rod is fixed at one end of the transmission bar, and one end of the connecting rod is fixed on the sleeve ring.

[0027] Through the above technical solution, when the transmission bar moves up and down, it drives the sealing plate to move up and down at the same time through the connection between the connecting rod and the ring, so as to realize the connection and disconnection between the water outlet on the lower cover plate and the space to be treated.

[0028] As a further improvement of the above scheme, a limiting slide groove is opened in the transmission bar, and a tooth profile plate is provided on one side of the limiting slide groove. At the same time, a transmission gear is fixed on the connecting rod, and the transmission gear is movably connected in the limiting slide groove and meshed with the tooth profile plate. At the same time, a sleeve is provided on the partition plate, and the transmission bar is inserted into the sleeve at a set position.

[0029] Through the above technical solution, the connecting rod drives the transmission gear to rotate simultaneously, and through the force of the engagement between the side of the transmission gear and the tooth profile plate, the transmission bar drives the upper sealing plate to move simultaneously, thereby realizing the height adjustment of the sealing plate.

[0030] As a further improvement of the above solution, an air collecting fan is installed on the air storage tank, and the air collecting fan is connected to the inside of the air storage tank.

[0031] Through the above technical solution, the air collection fan is specifically a high-pressure fan. Through the rotation of the blades inside the fan, work is done on the air, converting mechanical energy into kinetic energy and pressure energy of the gas, and transporting it to the bottom of the tank through the air pipe, so that the diaphragm expands upward, squeezing the sewage above the diaphragm for secondary filtration, recovery and backwashing operations.

[0032] As a further improvement of the above scheme, one end of the gas pipe is movably connected to a flow limiting rod, a ventilation groove is opened on the flow limiting rod, a resistance gasket is provided on the inner side of the ventilation groove, and a limit button is provided in the gas pipe. The limit button is slidably connected in the ventilation groove and fits on the resistance gasket.

[0033] A convex ring is arranged inside one end of the gas delivery pipe, and a conical spring is installed between the convex ring and the flow limiting rod.

[0034] Through the above technical solution, the ventilation groove remains in communication with the gas transmission pipe and the bottom space of the diaphragm. When the diaphragm is under the pressure of sewage, the gas entering the bottom space of the diaphragm can be discharged in the reverse direction. When the sewage above the diaphragm is stored to a certain amount, the bottom of the diaphragm presses the current-limiting rod, increasing the interface of the ventilation groove. Under the operation of the gas collection fan, the diaphragm expands rapidly upward, achieving the effect of squeezing the sewage above the diaphragm. At the same time, the conical spring is used to push the current-limiting rod back to its original position.

[0035] Compared with the prior art, the present invention provides an energy storage type large-flow backwashing filtration station, which has the following beneficial effects:

[0036] 1. In this energy storage type large-flow backwashing filtration station, a partition board and a filter plate are installed in the tank, and a ball valve is installed between the partition board and the filter plate. The ball valve is used to transfer the sewage discharged from the upper stream to the bottom space of the filter plate. Through the deformable characteristic of the diaphragm, the sewage transferred to the downstream is stored and energy is accumulated. When the sewage reaches a certain amount, the bottom of the diaphragm presses the current-limiting rod, allowing gas to be quickly filled. The diaphragm expands in the reverse direction, squeezing the sewage. After the sewage passes through the filter plate at the top for filtration, it is recycled and reused through the return pipe. A small amount of sewage containing impurities remains between the filter plate and the diaphragm. By opening the sewage discharge valve opening, the remaining small amount of sewage is discharged, effectively reducing the waste of water resources.

[0037] 2. In this energy storage type large-flow backwashing filtration station, an annular pipe is installed between the inner wall of the tank and the outside of the filter cylinder. The annular pipe is connected to the return pipe for water resource recycling and utilization. Under the continuous injection pressure, the return pipe distributes the recycled water resources into each spray pipe, and the spray pipe then cleans the filter cylinder in a backwashing manner. The cleaned water source can be recycled again, repeatedly completing the backwashing operation, effectively reducing the energy consumption and cost of the equipment.

[0055] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0056] Embodiment 1

[0057] Please refer to Figure 1 - Figure 9 As shown in the figure, a energy storage type large-flow backwashing filter station proposed in this embodiment includes a tank body 1, a filtering component 2, a cleaning component 3, a sealing plate 4, a regulating component 5, a flushing component 6 and a gas supply component 7. The side of the tank body 1 is successively provided with a water inlet valve port 101, a water outlet valve port 102, a return pipe 103 and a sewage discharge valve port 104 from top to bottom. The water inlet valve port 101 is connected to an external water supply pipe for conveying water source into the tank body 1, and the water outlet valve port 102 is connected to an external water delivery pipe for discharging the filtered water source in the tank body 1. The return pipe 103 is used to re-import the secondarily filtered water source back into the tank body 1, and under the cooperation with the flushing component 6, it realizes the reverse flushing operation of the filter cartridge, and the sewage discharge valve port 104 is used to discharge the dirt and a small amount of filtered water source in the water.

[0058] The filtering component 2 is installed in the tank body 1. The filtering component 2 is composed of a filter cartridge 201, an upper cover plate 202 and a lower cover plate 203. The filter cartridge 201 is installed between the upper cover plate 202 and the lower cover plate 203. At the same time, the edges of the upper cover plate 202 and the lower cover plate 203 are fixed on the inner wall of the tank body 1. The upper cover plate 202 and the lower cover plate 203 are fixed on the inner wall of the tank body 1 through the edges, so as to form an independent water storage space between the side of the filter cartridge 201 and the inner wall of the tank body 1 to store the filtered water source. The water source is filtered by being input into the filter cartridge 201, so that impurities stay in the filter cartridge 201, and the filtered water source flows into the water storage space.

[0059] An inlet water groove 204 is opened on the upper cover plate 202, and an outlet water hole 205 is opened on the lower cover plate 203. At the same time, the water inlet valve port 101 is located above the upper cover plate 202, and the water outlet valve port 102 is located at the bottom between the tank body 1 and the filter cartridge 201. When the water inlet valve port 101 inputs the water source, the water source flows into the filter cartridge 201 from the inlet water groove 204 for filtering. When discharging the impurities in the filter cartridge 201, in the state where the outlet water hole 205 is unblocked, the sewage containing impurities is discharged into the space to be treated between the sealing plate 4 and the partition plate 105.

[0060] A cleaning assembly 3 for cleaning the dirt on the inner wall of the filter cartridge 201 is installed inside the filter cartridge 201. The cleaning assembly 3 is used to scrape off the impurities attached to the filter cartridge 201, improving the filtration fluency and efficiency of the filter cartridge 201.

[0061] Inside the tank body 1 and at the bottom of the lower cover plate 203, a partition plate 105, a filter plate 106, and a diaphragm 108 are fixedly arranged in sequence from top to bottom. One end of the return pipe 103 communicates between the partition plate 105 and the filter plate 106, while the other end of the return pipe 103 communicates between the tank body 1 and the filter cartridge 201. At the same time, the sewage discharge valve port 104 communicates between the filter plate 106 and the diaphragm 108. The return pipe 103 is used to input the water source between the partition plate 105 and the filter plate 106 into the water storage space. When the sewage containing impurities enters the filtration space between the filter plate 106 and the diaphragm 108, under the influence of the gravity of the sewage, the diaphragm 108 deforms downward to store the sewage. When the diaphragm 108 is subjected to an upward thrust force, the sewage is secondarily filtered through the filter plate 106, and the filtered water source is re-input into the water storage space through the return pipe 103. At the same time, the diaphragm 108 is reset, and the impurities and a small part of the unfiltered water source are left between the filter plate 106 and the diaphragm 108. When the sewage discharge valve port 104 is opened, the impurities are discharged outside the tank body 1 through this part of the unfiltered water source.

[0062] A sealing plate 4 for blocking the drainage of the water outlet hole 205 is connected to the bottom of the filtration assembly 2. The top of the sealing plate 4 fits against the bottom of the lower cover plate 203 to block the water outlet hole 205, so that the normal filtration function can be realized inside the filter cartridge 201. When the sealing plate 4 is separated from the lower cover plate 203, the water source and impurities inside the filter cartridge 201 can be discharged through the water outlet hole 205.

[0063] An installation position 107 is provided on the axis of the partition plate 105 and the filter plate 106.

[0064] A regulation assembly 5 is installed inside the tank body 1. The regulation assembly 5 includes a ball valve 501 movably connected inside the installation position 107. A regulating member 51 for controlling the rotation of the ball valve 501 and the lifting of the sealing plate 4 is fixed on the side of the ball valve 501. The regulating member 51 is movably connected to the tank body 1. The installation position 107 is circularly concave inside, and the ball valve 501 matches the inner diameter of the installation position 107. By controlling the ball valve 501 to rotate clockwise and counterclockwise in the vertical direction through the regulating member 51, the communication and blocking between the space at the top of the partition plate 105 and the space at the bottom of the filter plate 106 are realized. At the same time, the regulating member 51 also controls the sealing plate 4 to change in height. When the sealing plate 4 moves downward, the water outlet hole 205 leaks, and at the same time, the interface of the ball valve 501 communicates with the top of the partition plate 105 and the bottom of the filter plate 106, so as to discharge the water source and impurities inside the filter cartridge 201 into the filtration space.

[0065] A flushing assembly 6 is installed in the tank body 1, and the flushing assembly 6 includes an annular tube 601 fixed on the inner wall of the tank body 1. One end of the return pipe 103 is connected to the annular tube 601, and a plurality of spray pipes 602 are equidistantly arranged on the annular tube 601. The water source after secondary filtration is input into the annular tube 601 through the return pipe 103, and the annular tube 601 distributes the water source to each spray pipe 602. Under the action of continuous input of the water source, the spray pipe 602 returns the secondary filtered water source to the filter cartridge 201 in a reverse flushing manner, and washes away impurities attached to the inner wall of the filter cartridge 201.

[0066] It should be further explained that when performing secondary filtration and back flushing operations, it is necessary to ensure that the ball valve 501 blocks the upper and lower spaces of the partition 105 and the filter plate 106, and at the same time the sealing plate 4 is reset and fits the bottom of the lower cover plate 203, and the drain valve port 104 is in a closed state, and the water inlet valve port 101 is in a closed state.

[0067] The side of the tank body 1 is connected to an air supply assembly 7, which consists of an air tank 701 and an air pipe 703. The two ends of the air pipe 703 are respectively connected to the air tank 701 and the interior of the tank body 1. Compressed gas is stored in the air tank 701 and is transported to the bottom space of the diaphragm 108 through the air pipe 703, thereby causing the diaphragm 108 to expand upward.

[0068] The working principle of the energy storage type large flow backwashing filter station proposed in this embodiment is: when in use, by connecting the water inlet valve port 101 to the water supply pipe and the water outlet valve port 102 to the water delivery pipe, by delivering water into the tank body 1, the water source enters from the top of the filter cartridge 201 and is discharged from the side of the filter cartridge 201, completing the filtration of the water source, and the filtered water source is output through the water outlet valve port 102. When it is necessary to clean the inside of the filter cartridge, by closing the water inlet valve port 101 and rotating the control unit 51, the interface of the ball valve 501 connects the space to be treated and the filter space, and at the same time the sealing plate 4 moves downward to open the water outlet hole 205. At this time, after the sewage in the filter cartridge 201 contains impurities and enters the space to be treated, the sewage enters the filter space through the interface of the ball valve 501. At this time, the diaphragm 108 gradually deforms downward according to the injection of sewage. When the sewage is completely discharged, the control unit 51 is rotated in the opposite direction so that the ball valve 501 blocks the space to be treated and the filter space. At this time, the reflux pipe 103 serves as the only reflux channel At the same time, the sealing plate 4 is reset, and then the air supply component 7 is controlled to operate, and gas is input to the bottom of the diaphragm 108 to expand the diaphragm 108 upward. At this time, the sewage above the diaphragm is filtered twice through the filter plate 106, and under the action of the continuous expansion of the diaphragm 108, pressure is formed, and the secondary filtered water is input from the reflux pipe 103 to the annular pipe 601. The annular pipe 601 distributes the secondary filtered water to each spray pipe 602, and under the action of pressure, it is splashed on the outside of the filter cartridge 201 to achieve a reverse flushing effect, and the impurities attached to the inner wall of the filter cartridge 201 are washed away. After the secondary filtered water is completely used up, the control button is turned again to discharge the impurities and sewage, and the control button is turned in the opposite direction to close the ball valve. The reciprocating operation is performed to achieve multiple flushing of the filter cartridge 201. After the last flushing is completed, the diaphragm 108 is in a horizontal state. At this time, there is a small amount of sewage and repeatedly filtered impurities in the filter space. At this time, the sewage and impurities inside can be discharged by opening the sewage valve port 104.

[0069] Embodiment 2

[0070] See also Figure 2 - Figure 4 and Figure 5 As shown, the energy storage type large flow backwash filter station mentioned in this embodiment, on the basis of embodiment one, this embodiment also includes that the cleaning component 3 is composed of a rotating rod 301 and a scraper 306, the side of the rotating rod 301 is movably sleeved with a sleeve 304, and a sleeve rod 305 is movably sleeved in the sleeve 304, one end of the sleeve rod 305 is fixed on the scraper 306, and the scraper 306 is attached to the inner side of the filter cartridge 201, and at the same time, a driving motor 109 is fixed on the tank body 1, and the output end of the driving motor 109 is fixed on the rotating rod 301.

[0071] More specifically, the output end of the drive motor 109 has a bidirectional rotation function. During operation, the output end drives the rotating rod 301 to rotate, causing the scraper 306 to scrape and clean the inner wall of the filter cylinder 201, preventing excessive impurities from adhering to the inner wall of the filter cylinder 201 and improving the smoothness of water quality filtration.

[0072] It should be further noted that two sleeves 304 are relatively installed at the top and bottom of the rotating rod 301. The lengths of the two ends of the sleeve 304 centered on the rotating rod 301 are the same to ensure stability during rotation. The telescopic movement of the sleeve rod 305 movably sleeved at both ends of the sleeve 304 enables the scraper 306 to fit inside the filter cylinder 201 with different diameters. At the same time, when the scraper 306 scrapes against a harder convex structure, the sleeve rod 305 can also stretch and contract inside the sleeve 304, enabling the scraper 306 to skip over the convex obstacle and scrape and clean other positions inside the filter cylinder 201.

[0073] Furthermore, a tension spring 307 is movably sleeved on the side of the sleeve rod 305. Both ends of the tension spring 307 are attached between the sleeve 304 and the scraper 306. At the same time, positioning rings 308 are threadedly connected to both ends of the sleeve 304, and the positioning rings 308 are attached to the side of the rotating rod 301.

[0074] More specifically, under the action of the force of both ends of the tension spring 307 abutting between the sleeve 304 and the back of the scraper 306, the scraper 306 can scrape and clean inside the filter cylinder 201 with different diameters and improve the degree of fit between the scraper 306 and the inner wall of the filter cylinder 201.

[0075] Furthermore, a first turning knob 302 and a second turning knob 303 are respectively provided at both ends of the rotating rod 301. The first turning knob 302 is rotatably connected to the axis of the upper cover plate 202, while the second turning knob 303 is rotatably connected to the axis of the lower cover plate 203.

[0076] More specifically, by rotatably connecting the first turning knob 302 and the second turning knob 303 to the axes of the corresponding cover plates, the stability of the rotation of the rotating rod 301 is improved.

[0077] Furthermore, a stabilizing sleeve rod 309 is fixed at one end of the rotating rod 301. At the same time, a collar 401 is provided on the axis at the bottom of the sealing plate 4. The sealing plate 4 and the collar 401 are movably sleeved on the stabilizing sleeve rod 309. At the same time, a limiting button 310 is fixed at one end of the stabilizing sleeve rod 309, and the limiting button 310 abuts against the bottom of the collar 401.

[0078] More specifically, when the height of the sealing plate 4 changes, the collar 401 and the sealing plate 4 slide up and down simultaneously on the side of the stable sleeve rod 309, thereby improving the stability of the lifting of the sealing plate 4. At the same time, the height of the sealing plate 4 descending is restricted by the limit button 310 installed at the bottom end of the stable sleeve rod 309 to prevent the sealing plate 4 from detaching from the stable sleeve rod 309.

[0079] Further, the regulating member 51 includes connecting rods 502 fixed to both ends of the ball valve 501. The connecting rods 502 penetrate through the installation position 107 and are rotatably connected to the side of the tank body 1. An adjusting knob 503 is fixed to one end of the connecting rod 502.

[0080] More specifically, by rotating the adjusting knob 503, the ball valve 501 rotates in the vertical direction, enabling the interface of the ball valve 501 to communicate the space to be treated and the filtration space, so that the sewage enters the filtration space from the space to be treated and waits for secondary filtration recovery and backwashing operations.

[0081] Further, the regulating member 51 further includes a transmission strip 505 movably connected to the connecting rod 502. A linkage rod 508 is fixed to one end of the transmission strip 505, and one end of the linkage rod 508 is fixed to the collar 401.

[0082] More specifically, when the transmission strip 505 moves up and down, under the connection of the linkage rod 508 and the collar 401, the sealing plate 4 is driven to move up and down simultaneously, realizing the on-off of the water outlet hole 205 on the lower cover plate 203 and the space to be treated.

[0083] Further, a limiting chute 506 is formed in the transmission strip 505. A toothed profile plate 507 is provided on one side in the limiting chute 506. At the same time, a transmission gear 504 is fixed to the connecting rod 502. The transmission gear 504 is movably connected in the limiting chute 506 and meshes with the toothed profile plate 507. At the same time, a sleeve 1051 is provided on the partition plate 105, and the transmission strip 505 is inserted into the sleeve 1051 at a set position.

[0084] More specifically, the connecting rod 502 drives the transmission gear 504 to rotate simultaneously. Under the acting force of the side of the transmission gear 504 meshing with the toothed profile plate 507, the transmission strip 505 drives the upper sealing plate 4 to move simultaneously, realizing the height adjustment of the sealing plate 4.

[0085] Embodiment III

[0086] Please refer to Figure 1 、 Figure 3 、 Figure 5 and Figure 7 As shown in, the energy storage type large-flow backwashing filtration station proposed in this embodiment, on the basis of Embodiment II, this embodiment further includes that an air collecting fan 702 is installed on the air storage tank 701, and the air collecting fan 702 is connected to the inside of the air storage tank 701.

[0087] More specifically, the air collecting fan 702 is specifically a high-pressure fan. By the rotation of the blades inside the fan, work is done on the air, converting mechanical energy into the kinetic energy and pressure energy of the gas, and the gas is transported to the bottom of the tank body 1 through the air delivery pipe 703, so that the diaphragm 108 expands upward, squeezing the sewage above the diaphragm for secondary filtration recovery and backwashing operations.

[0088] It should be further noted that when the air collecting fan 702 stops rotating and the diaphragm 108 is squeezed, the gas flows reversely, discharging the gas in the space at the bottom of the diaphragm 108.

[0089] Furthermore, one end of the air delivery pipe 703 is movably sleeved with a flow-limiting rod 704. An air vent groove 705 is formed on the flow-limiting rod 704, and a resistance gasket 709 is arranged inside the air vent groove 705. At the same time, a limiting button 708 is arranged inside the air delivery pipe 703. The limiting button 708 is slidably connected in the air vent groove 705 and fits on the resistance gasket 709.

[0090] Inside one end of the air delivery pipe 703, there is a convex ring 706, and a conical spring 707 is installed between the convex ring 706 and the flow-limiting rod 704.

[0091] More specifically, the air vent groove 705 is in a communicating state with the air delivery pipe 703 and the space at the bottom of the diaphragm 108, so that when the diaphragm 108 is under the pressure of the sewage, the gas entering the space at the bottom of the diaphragm 108 can be discharged reversely. When the sewage above the diaphragm 108 is stored to a certain amount, the bottom of the diaphragm 108 presses the flow-limiting rod 704, increasing the interfaces of the air vent groove 705. Under the operation of the air collecting fan 702, the diaphragm 108 expands upward rapidly, achieving the effect of squeezing the sewage above the diaphragm.

[0092] Moreover, when the flow-limiting rod 704 generates displacement, the flow-limiting rod 704 is pushed upward by the conical spring 707 for resetting. During the resetting, under the action of the limiting button 708 movably sleeved in the air vent groove 705 and the side of the limiting button 708 fitting on the resistance gasket 709, the stability of the displacement of the flow-limiting rod 704 is ensured, and at the same time, the displacement speed of the flow-limiting rod 704 is reduced, enabling the flow-limiting rod 704 to be reset slowly under the push of the conical spring 707, so as to ensure that enough gas is filled into the space at the bottom of the diaphragm 108.

[0093] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
