Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and particularly relates to an integrated water treatment device. Background Art

[0002] Integrated water treatment devices usually use membrane bioreactors (MBRs). The main components of common membrane bioreactors include flat membranes, spiral wound membranes, hollow membranes, etc., among which flat membranes are a main form. The flat membrane bioreactor mainly includes a support frame, a plurality of flat membrane elements installed on the support frame, and an aeration device installed at the bottom of the support frame. When the flat membrane bioreactor is working, it is hoisted into the biological reaction tank, and the flat membrane bioreactor is immersed in sewage. After being filtered by the flat membrane elements, the clear water is pumped into the clear water tank under the action of a suction pump. The aeration device is used for aeration to stir the water body, accelerate oxygenation. At the same time, the generated bubbles quickly pass through the membrane surface, and the shear force generated by the hydraulic circulation flushes the membrane surface, taking away the sludge deposited on the membrane surface and effectively preventing membrane fouling.

[0003] Chinese Patent with Publication No. CN107902751B discloses a flat membrane module support, which includes columns, crossbeams and longitudinal beams. The two ends of the crossbeam and the longitudinal beam are respectively connected to a column to form a cuboid-shaped frame. The crossbeam includes a first crossbeam and a second crossbeam arranged in sequence from bottom to top. The second crossbeam contracts inwards relative to the first crossbeam, and an inclined panel is arranged between the first crossbeam and the second crossbeam; the longitudinal beam includes a first longitudinal beam and a second longitudinal beam. The first longitudinal beam is at the same height as the first crossbeam, and the second longitudinal beam is at the same height as the second crossbeam. A vertical panel is arranged between the first longitudinal beam and the second longitudinal beam.

[0004] The above patent guides the aeration at the bottom of the pool through the area enclosed by the inclined panel and the vertical panel, converges the bubbles, makes the bubbles scour the flat membrane elements more powerfully, and reduces membrane fouling. However, in the actual implementation process, since the flat membrane elements are vertically installed on the support, the bubbles will be restricted by the membrane sheets during the rising process and can only move vertically upward along the surface of the membrane sheets. The movement path of the bubbles is relatively single, lacking lateral disturbance and diffusion, and it is easy to form a dominant channel with the least resistance, resulting in the phenomenon of bubble short-circuit. Moreover, the bubbles are easy to aggregate with each other to form large bubbles during the rising process and quickly pass through the membrane module, resulting in insufficient scouring of the upper half of the membrane sheet by the bubbles, and pollutants are easy to accumulate on the membrane surface.

[0005] Therefore, there is a need in the art for an integrated water treatment device to solve the above problems. Summary of the Invention

[0006] The present invention provides an integrated water treatment device, aiming to solve the problems in the related art that the diaphragm and the bubble flotation direction are the same, which is prone to the phenomena of bubble short circuit and bubble aggregation, resulting in a short residence time of bubbles on the diaphragm, uneven distribution, and poor scouring and cleaning effects on the diaphragm.

[0007] An integrated water treatment device of the present invention includes a box body, an operation room, a reaction tank, and an anoxic tank that are sequentially arranged in the box body from left to right. A flat membrane reactor is arranged in the reaction tank. The flat membrane reactor includes a mounting frame, a diaphragm mounted on the mounting frame, an integrated pipe communicating with the diaphragm, and an air diffuser pipe arranged below the diaphragm. The diaphragms are evenly arranged at intervals in the front-rear direction, and each diaphragm is rotatably connected to the mounting frame. A push rod is arranged at the top of each diaphragm, and a first driving component for driving the push rod to drive the diaphragm to rotate is arranged in the box body.

[0008] In the initial state, the diaphragm is in a vertical state. This state can ensure a good filtration effect at the initial stage of sewage treatment. However, as the treatment time prolongs, the pollutants attached to the diaphragm gradually increase, which will lead to a decrease in water flux. The present invention drives the push rod to drive the diaphragm to swing back and forth in the front-rear direction through the first driving component. The movement trajectory of the bubbles can be optimized. The bubbles will slide along the surface of the diaphragm during the rising process, prolonging the contact time between the bubbles and the pollutants and improving the peeling effect on the pollutants on the diaphragm. Moreover, the inclined diaphragm makes the scouring direction of the bubbles on the membrane surface no longer perpendicular to the membrane surface, but forms an oblique shear force, which is more likely to peel off the pollutants attached to the surface of the diaphragm and enhance the scouring effect of the bubbles on the diaphragm. In addition, the inclined setting of the diaphragm can change the rising path of the bubbles, forcing the bubbles to diffuse horizontally between the membranes, improving the overall gas-liquid contact efficiency, making the bubbles cover the surface of the diaphragm more evenly, avoiding the aggregation of bubbles in local areas, reducing the scouring dead angles, and improving the overall cleaning efficiency.

[0009] Preferably, a water outlet cavity communicating with the integrated pipe is opened at the top of the diaphragm. A piston is slidably connected in the water outlet cavity in the left-right direction. The piston is connected to the right side wall of the water outlet cavity through a first spring. A conical section is arranged at a position near the left end of the water outlet cavity. The first spring presses the piston against the conical section. The piston is connected to the push rod through a connecting rod. An avoidance groove for the push rod to move in the left-right direction is opened on the diaphragm. When the push rod follows the piston to move to a preset position, the first driving component drives the push rod to drive the diaphragm to rotate.

[0010] Through the connection design between the piston and the lever, and the sliding of the piston in the water outlet chamber due to the change in negative pressure, the automatic correlation between the diaphragm swing and the accumulation amount of pollutants on the diaphragm is realized. When the pollutants on the diaphragm increase, the negative pressure increases, and the piston drives the lever to automatically move to the preset position, thereby triggering the swing of the diaphragm without manual intervention, improving the automation degree of the system; moreover, the change in the negative pressure inside the diaphragm is used to directly control the position of the lever, and then control the swing of the diaphragm. This control method is accurate and direct, can accurately reflect the accumulation of pollutants on the diaphragm, and ensure that the diaphragm swings at the appropriate time to maintain its filtration efficiency.

[0011] Preferably, the first driving assembly includes a first automatic telescopic cylinder fixedly connected to the box body and a first pushing plate connected to the driving end of the first automatic telescopic cylinder. The first pushing plate is provided with pushing grooves corresponding to each of the levers at intervals in the front-back direction. A contraction part is arranged at a position near the right end of the pushing groove. The first automatic telescopic cylinder drives the first pushing plate to reciprocate in the front-back direction. When the lever moves to the contraction part, the first pushing plate pushes the lever to drive the diaphragm to swing back and forth.

[0012] The first driving assembly adopts a combined structure of a first automatic telescopic cylinder and a first pushing plate. This design structure is clear, easy to manufacture and assemble. The pushing grooves corresponding to each lever opened on the first pushing plate and the contraction part arranged at the position near the right end of the pushing groove enable the lever to be accurately pushed by the first pushing plate when it moves to a specific position (i.e., the contraction part). This design ensures that the lever receives a pushing force at the correct time and position, thereby driving the diaphragm to swing accurately back and forth. Other levers that do not move to the contraction part are not driven by the pushing plate, and the corresponding diaphragms continue to remain in the vertical state.

[0013] Preferably, a second automatic telescopic cylinder is fixedly installed on the box body. The driving end of the second automatic telescopic cylinder is fixedly connected to a second pushing plate. The second pushing plate is slidably connected to the first pushing plate in the front-back direction. The driving end of the first automatic telescopic cylinder is fixedly connected to a mounting plate. The first pushing plate is slidably connected to the mounting plate in the left-right direction. When the second automatic telescopic cylinder drives the second pushing plate to drive the first pushing plate to move to the right, the first pushing plate pushes the lever through the pushing groove to drive the piston to move to the right.

[0014] In the initial stage of treating sewage, the second automatic telescopic cylinder drives the second pushing plate to drive the first pushing plate to move to the right. The first pushing plate pushes the lever through the pushing groove to drive the piston to move to the right, connecting the water outlet chamber and the inside of the diaphragm, reducing the suction burden of the suction pump, enabling the suction pump to be fully used to suck clean water, and ensuring the clean water output of the water treatment device.

[0015] Preferably, a flow guiding assembly is provided between two adjacent diaphragms. The flow guiding assembly includes a flow guiding frame connected to the mounting frame and a flow guiding plate rotatably connected to the flow guiding frame. A second driving assembly for driving the flow guiding plate to rotate is provided on the box body.

[0016] By adjusting the angle of the flow guiding plate through the second driving assembly, the water flow and air bubbles can impact the surface of the diaphragm in a more appropriate direction and with greater force, which can more effectively wash down the pollutants attached to the diaphragm, enhance the self-cleaning ability of the diaphragm, greatly reduce the risk of diaphragm blockage, contribute to maintaining the continuous and stable operation of the water treatment device, reduce the downtime for maintenance caused by diaphragm blockage, extend the service life of the diaphragm, and improve the economy and reliability of the entire water treatment device.

[0017] Preferably, the flow guiding frame includes two symmetrically arranged flow guiding rods on the left and right. The flow guiding rods are fixedly connected to the mounting frame. On the sides of the two flow guiding rods facing each other, mounting rods are respectively slidably connected vertically. A plurality of flow guiding plates are evenly arranged at intervals vertically, and the plurality of flow guiding plates are respectively rotatably connected to the mounting rods. A driving component for driving the mounting rods to move vertically is provided on the box body.

[0018] When there are a large number of pollutants on the surface of the diaphragm and the filtration flux drops significantly, it is too slow to clean the pollutants only by air bubbles and water flow, which affects the continuous use of the water treatment equipment. The second driving assembly drives the flow guiding plate to rotate until the edge of the flow guiding plate gently fits the outer surface of the diaphragm, and then the automatic telescopic cylinder three is controlled to drive the pressing plate to press the mounting rod downward. The mounting rod drives the flow guiding plate to move downward, realizing the direct scraping of the pollutants attached to the diaphragm by the flow guiding plate, and significantly improving the cleaning efficiency.

[0019] Preferably, the driving component includes an automatic telescopic cylinder three fixedly installed on the box body, a pressing plate connected to the driving end of the automatic telescopic cylinder three, and a second spring connected between the bottom of the mounting rod and the flow guiding rod. The automatic telescopic cylinder three presses the mounting rod to move downward relative to the flow guiding rod through the pressing plate, and the second spring is used to drive the mounting rod to move upward and reset.

[0020] Through the combination of the automatic telescopic cylinder three and the pressing plate, precise control of the downward movement of the mounting rod and the flow guiding plate can be achieved. This automated operation reduces manual intervention and improves the accuracy and efficiency of the operation.

[0021] Preferably, the second driving assembly includes a movable frame slidably connected vertically inside the mounting rod and a top push rod disposed at the bottom of the pressing plate. Tooth segments are arranged vertically and staggeredly on the front and rear sides of the movable frame. A gear is fixedly connected to the rotating shaft of the flow guide plate rotatably connected to the mounting rod. The top push rod is correspondingly arranged with each flow guide assembly. The top push rod vertically penetrates the mounting rod and is fixedly connected to the movable frame. The automatic telescopic cylinder three drives the top push rod to push the movable frame through the pressing plate, and the tooth segments inside the movable frame drive the gear to drive the flow guide plate to rotate.

[0022] The design of the second driving assembly makes full use of the space inside the mounting rod. Through the combination of the movable frame and the tooth segments, the driving of multiple flow guide plates in a limited space is realized. This compact structural design helps to save the equipment space and makes the whole water treatment device more compact and efficient. The top push rod is correspondingly arranged with each flow guide assembly, which means that the pressing plate can simultaneously press all the top push rods to drive the corresponding multiple flow guide plates to rotate, ensuring the consistency of the actions of each flow guide plate. This synchronous driving method helps to ensure the uniform distribution of water flow and bubbles on the surface of the diaphragm, thereby improving the cleaning effect.

[0023] Preferably, a third spring is connected between the part of the top push rod located at the top of the mounting rod and the mounting rod. The third spring is used to drive the movable frame to move upward and reset.

[0024] Preferably, the driving end of the automatic telescopic cylinder three is fixedly connected with an inverted U-shaped block. The pressing plate is located inside the inverted U-shaped block, and the top of the top push rod is fixedly connected to the pressing plate.

[0025] The beneficial effects of the present invention are as follows: The present invention drives the lever to drive the diaphragm to swing reciprocally in the front and rear directions through the first driving assembly, which can optimize the movement trajectory of the bubbles. The bubbles will slide along the surface of the diaphragm during the rising process, prolonging the contact time between the bubbles and the pollutants and improving the peeling effect on the pollutants on the diaphragm. Moreover, the inclined diaphragm makes the scouring direction of the bubbles on the membrane surface no longer perpendicular to the membrane surface, but forms an oblique shear force, which is more likely to peel off the pollutants attached to the surface of the diaphragm and enhance the scouring effect of the bubbles on the diaphragm. In addition, the inclined setting of the diaphragm can change the rising path of the bubbles, forcing the bubbles to diffuse laterally between the membranes, improving the overall gas-liquid contact efficiency, making the bubbles cover the surface of the diaphragm more evenly, avoiding the aggregation of bubbles in local areas, reducing the scouring dead angles, and improving the overall cleaning efficiency.

Detailed implementation manners

[0036] The embodiments of the present invention will be described in detail below, and examples of the embodiments are shown in the drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0037] As Figures 1 to 9As shown in the figure, an integrated water treatment device of the present invention includes a box body 1, an operation room 2, a reaction tank 3 and an anoxic tank 4 which are arranged in the box body 1 from left to right in sequence. A flat membrane reactor is arranged in the reaction tank 3. The flat membrane reactor includes a mounting frame 5, a membrane sheet 6 mounted on the mounting frame 5, an integrated pipe 7 communicating with the membrane sheet 6, and an air diffuser pipe 8 arranged below the membrane sheet 6. The operation room 2 is provided with a water inlet pipe (not shown in the figure), a water outlet pipe (not shown in the figure) and a sewage discharge pipe (not shown in the figure). Sewage enters the anoxic tank 4 through the water inlet pipe for pretreatment. The water after pretreatment enters the reaction tank 3. After the sewage is filtered by the flat membrane reactor, clear water is formed. The suction pump 10 pumps the clear water into the integrated pipe 7 and sends it out through the water outlet pipe. A sewage pumping pump (not shown in the figure) is arranged in the box body 1, and the sewage pumping pump sucks the sludge at the bottom of the reaction tank 3 into the sewage discharge pipe and discharges it.

[0038] As Figure 2 and Figure 4 shown in the figure, the membrane sheets 6 of the flat membrane reactor are evenly arranged at intervals in the front-rear direction. Mounting grooves 51 are symmetrically formed on the left and right side walls of the mounting frame 5. The left and right sides of each membrane sheet 6 respectively extend with mounting posts 61. Each membrane sheet 6 is mounted in the mounting groove 51 through the mounting post 61 and is rotatably connected with the mounting groove 51. A lever 62 is arranged at the top of each membrane sheet 6, and a first driving assembly for driving the lever 62 to drive the membrane sheet 6 to rotate is arranged in the box body 1.

[0039] In the initial state, the membrane sheet 6 is in a vertical state. This state can ensure good filtration effect in the initial stage of sewage treatment. However, as the treatment time prolongs, the pollutants attached to the membrane sheet 6 gradually increase, which will lead to a decrease in water flux. At this time, by driving the lever 62 through the first driving assembly to drive the membrane sheet 6 to swing back and forth in the front-rear direction, the movement trajectory of the bubbles can be optimized. The bubbles will slide along the surface of the membrane sheet 6 during the rising process, prolonging the contact time between the bubbles and the pollutants, and improving the peeling effect on the pollutants on the membrane sheet 6. Moreover, the inclined membrane sheet 6 makes the scouring direction of the bubbles on the membrane surface no longer perpendicular to the membrane surface, but forms an oblique shear force, which is more likely to peel off the pollutants attached to the surface of the membrane sheet 6 and enhance the scouring effect of the bubbles on the membrane sheet 6. In addition, the inclined arrangement of the membrane sheet 6 can change the rising path of the bubbles, forcing the bubbles to diffuse laterally between the membranes, improving the overall gas-liquid contact efficiency, making the bubbles cover the surface of the membrane sheet 6 more evenly, avoiding the aggregation of bubbles in local areas, reducing the scouring dead corners, and improving the overall cleaning efficiency.

[0040] As Figure 2 and Figure 5As shown, a water outlet cavity 63 communicating with the integrated pipe 7 is formed at the top of the diaphragm 6. A piston 64 is slidably connected in the water outlet cavity 63 in the left-right direction. The piston 64 is connected to the right side wall of the water outlet cavity 63 through a first spring 65. A tapered section 631 is provided at a position near the left end of the water outlet cavity 63, and the diameter of the tapered section 631 gradually decreases from right to left. The first spring 65 presses the piston 64 against a position near the left end of the tapered section 631, and the piston 64 seals the water outlet cavity 63, separating the water outlet cavity 63 from the inside of the diaphragm 6. The piston 64 is connected to the lever 62 through a connecting rod 641, and an avoidance groove 66 for the lever 62 to move in the left-right direction is formed on the diaphragm 6. When the suction pump 10 sucks clear water, it will adsorb the piston 64 to compress the first spring 65 to the right, connecting the water outlet cavity 63 with the inside of the diaphragm 6, so that the diaphragm 6 can filter sewage normally.

[0041] As Figure 2 and Figure 6 shown, the first driving assembly includes a first automatic telescopic cylinder 11 fixedly connected to the box body 1 and a first pushing plate 12 connected to the driving end of the first automatic telescopic cylinder 11. The first pushing plate 12 is provided with corresponding pushing grooves 121 for each lever 62 at intervals in the front-rear direction. A contraction part 122 is provided at a position near the right end of the pushing groove 121. The first automatic telescopic cylinder 11 drives the first pushing plate 12 to reciprocate in the front-rear direction. When the lever 62 moves to the contraction part 122, the first pushing plate 12 pushes the lever 62 to drive the diaphragm 6 to swing back and forth. As an example, the first automatic telescopic cylinder 11 is an electric telescopic cylinder.

[0042] A second automatic telescopic cylinder 13 is fixedly installed on the box body 1. The driving end of the second automatic telescopic cylinder 13 is fixedly connected to a second pushing plate 14. The second pushing plate 14 is slidably connected to the first pushing plate 12 in the front-rear direction. The driving end of the first automatic telescopic cylinder 11 is fixedly connected to a mounting plate 111. A T-shaped groove 112 extending in the left-right direction is formed on the mounting plate 111. The first pushing plate 12 is slidably connected to the T-shaped groove 112 in the left-right direction. As an example, the second automatic telescopic cylinder 13 is an electric telescopic cylinder.

[0043] As Figure 2 、 Figure 5 and Figure 6As shown in the figure, at the initial stage of sewage treatment, the automatic telescopic cylinder two 13 drives the pushing plate two 14 to drive the pushing plate one 12 to move to the right. The pushing plate one 12 pushes the lever 62 through the pushing groove 121 to drive the piston 64 to move to the right, connecting the water outlet cavity 63 and the inside of the diaphragm 6, reducing the suction burden of the suction pump 10, enabling the suction pump 10 to be fully used to suck clear water, and ensuring the clear water output of the water treatment device. After operating for a period of time, more and more pollutants will adhere to the diaphragm 6. Control the automatic telescopic cylinder two 13 to drive the pushing plate two 14 to drive the pushing plate one 12 to move to the left to reset. After the lever 62 and the piston 64 lose the push of the pushing plate one 12, the resilience of the first spring 65 between the piston 64 and the water outlet cavity 63 will drive the piston 64 to move to the left for a certain distance. However, due to the suction force of the suction pump 10, the piston 64 will not be completely blocked by the first spring 65 to seal the water outlet cavity 63, and the water outlet cavity 63 is still connected to the inside of the diaphragm 6.

[0044] As more and more pollutants adhere to the diaphragm 6, the negative pressure inside the diaphragm 6 will become larger and larger, the suction force of the suction pump 10 on the piston 64 will gradually increase, the piston 64 will drive the lever 62 to gradually move to the right. When the lever 62 moves to the contraction part 122 of the pushing groove 121, control the automatic telescopic cylinder one 11 to drive the mounting plate 111 to drive the pushing plate one 12 to move in the front-rear direction. The contraction part 122 of the pushing groove 121 pushes the lever 62 to drive the diaphragm 6 to swing back and forth, thereby improving the flushing and cleaning efficiency of the bubbles on the pollutants attached to the diaphragm 6, increasing the filtration flux of the diaphragm 6, and extending the service life of the diaphragm 6.

[0045] As Figure 3 and Figure 7 As shown in the figure, in order to further reduce the pollutants attached to the diaphragm 6, in this embodiment, a diversion component is provided between two adjacent diaphragms 6. The diversion component includes a diversion frame fixedly connected to the mounting frame 5 and a diversion plate 9 rotatably connected to the diversion frame. A second driving component for driving the diversion plate 9 to rotate is provided on the box body 1. By adjusting the angle of the diversion plate 9 through the second driving component, the water flow and bubbles can impact the surface of the diaphragm 6 in a more appropriate direction and strength, which can more effectively wash down the pollutants attached to the diaphragm 6, enhance the self-cleaning ability of the diaphragm 6, reduce the risk of blockage of the diaphragm 6, and extend the service life of the diaphragm 6.

[0046] The diversion frame includes two symmetrically arranged diversion rods 91 on the left and right. The diversion rods 91 are fixedly connected to the mounting frame 5. On the side of the two diversion rods 91 facing each other, mounting rods 92 are respectively slidably connected in the vertical direction. A plurality of diversion plates 9 are evenly arranged at intervals in the vertical direction, and the plurality of diversion plates 9 are respectively rotatably connected to the mounting rods 92. A driving member for driving the mounting rods 92 to move in the vertical direction is provided on the box body 1.

[0047] Refer to Figure 3 、 Figure 7 and Figure 8The driving component includes an automatic telescopic cylinder 3 15 fixedly mounted on the box 1, a pressing plate 16 connected to the driving end of the automatic telescopic cylinder 3 15, and a spring 2 93 connected between the bottom of the mounting rod 92 and the guide rod 91. The automatic telescopic cylinder 3 15 presses the mounting rod 92 to move downward relative to the guide rod 91 through the pressing plate 16, and the spring 2 93 is used to drive the mounting rod 92 to move upward and reset. As an example, the automatic telescopic cylinder 3 15 is an electric telescopic cylinder.

[0048] When there are many pollutants on the surface of the diaphragm 6 and the filtration flux is greatly reduced, the efficiency of cleaning the pollutants only by bubbles and water flow is too slow, which affects the continuous use of the water treatment equipment. The guide plate 9 is driven by the driving component 2 to rotate until the edge of the guide plate 9 lightly fits the outer surface of the diaphragm 6, and then the automatic telescopic cylinder 3 15 is controlled to drive the pressing plate 16 to press the installation rod 92 downward. The installation rod 92 drives the guide plate 9 to move downward, so that the guide plate 9 scrapes off the pollutants attached to the diaphragm 6 downward.

[0049] like Figure 3 and Figure 9 As shown, the second driving assembly includes a movable frame 94 slidably connected to the mounting rod 92 in the vertical direction and a push rod 95 fixedly connected to the bottom of the pressing plate 16. The front and rear sides of the movable frame 94 are vertically staggered with tooth segments 941. A gear 90 is fixedly connected to the rotating shaft on which the guide plate 9 is rotatably connected to the mounting rod 92. The push rod 95 is arranged corresponding to each guide assembly. The push rod 95 vertically penetrates the mounting rod 92 and is fixedly connected to the movable frame 94. A spring 3 96 is connected between the part of the push rod 95 located at the top of the mounting rod 92 and the mounting rod 92. When the push rod 95 is not subjected to external force, the spring 3 96 enables the push rod 95 to drive the movable frame 94 to be located at the top of the mounting rod 92. The elastic coefficient of the spring 3 96 is smaller than the elastic coefficient of the spring 2 93.

[0050] The driving end of the automatic telescopic cylinder three 15 is fixedly connected with an inverted U-shaped block 151, and the pressing plate 16 is located in the inverted U-shaped block 151. When the automatic telescopic cylinder three 15 drives the pressing plate 16 through the inverted U-shaped block 151 to drive the push rod 95 to move downward, the push rod 95 squeezes the spring three 96 to contract, and pushes the movable frame 94 to move downward relative to the mounting rod 92. The tooth segment 941 in the movable frame 94 contacts the gear 90 on the guide plate 9 and drives the gear 90 to drive the guide plate 9 to rotate. When the movable frame 94 is against the bottom of the mounting rod 92, the movable frame 94 drives the mounting rod 92 to move downward, and the mounting rod 92 drives the guide plate 9 to move downward, and the mounting rod 92 squeezes the spring two 93 to contract.

[0051] The specific working principle of an integrated water treatment device of the present invention is as follows: Sewage is pumped from the water inlet pipe into the anoxic tank 4 for pretreatment, and the water after pretreatment enters the reaction tank 3 for filtration. In the initial state, the diaphragm 6 is in a vertical state. The automatic telescopic cylinder two 13 drives the second push plate 14 to drive the first push plate 12 to move to the right. The first push plate 12 pushes the lever 62 through the push groove 121 to drive the piston 64 to move to the right, connecting the water outlet cavity 63 and the inside of the diaphragm 6; After running for a set duration, control the automatic telescopic cylinder two 13 to drive the second push plate 14 to drive the first push plate 12 to move to the left to reset. After the lever 62 and the piston 64 lose the push of the first push plate 12, the resilience of the first spring 65 between the piston 64 and the water outlet cavity 63 will drive the piston 64 to move to the left for a certain distance. At this time, the lever 62 is located in the push groove 121 and to the left of the contraction part 122; As the pollutants on the diaphragm 6 increase, the negative pressure inside the diaphragm 6 will become larger and larger, and the suction force of the suction pump 10 on the piston 64 will gradually increase. The piston 64 will drive the lever 62 to move to the right gradually. Control the automatic telescopic cylinder one 11 to drive the mounting plate 111 to drive the first push plate 12 to reciprocate in the front-rear direction. The lever 62 located to the left of the contraction part 122 will not be interfered by the wall of the push groove 121. At this time, the filtration flux of the diaphragm 6 corresponding to this lever 62 is still within the normal range, while the filtration flux of the diaphragm 6 corresponding to the lever 62 entering the contraction part 122 has been lower than the normal range. This lever 62 will drive the corresponding diaphragm 6 to swing back and forth under the push of the wall of the mounting groove 51, enhancing the scouring and cleaning of the pollutants on the diaphragm 6 by the bubbles; When the filtration flux of the diaphragm 6 is lower than the preset minimum value, restore the diaphragm 6 to the vertical state. Control the automatic telescopic cylinder three 15 to drive the pressing plate 16 to drive the push rod 95 to move downward. The push rod 95 squeezes the third spring 96 to contract and pushes the movable frame 94 to move downward relative to the mounting rod 92. The tooth section 941 in the movable frame 94 contacts the gear 90 on the guide plate 9 and drives the gear 90 to drive the guide plate 9 to rotate. When the movable frame 94 abuts against the bottom of the mounting rod 92, the guide plate 9 gently fits on the outer surface of the diaphragm 6. As the pressing plate 16 continues to press down, the movable frame 94 drives the mounting rod 92 to move downward, and the mounting rod 92 drives the guide plate 9 to move downward, so that the guide plate 9 scrapes the pollutants on the surface of the diaphragm 6.
