Description

Technical Field

[0001] This invention relates to the technical field of water pollution treatment equipment, and in particular to an integrated wastewater treatment equipment for the degradation of oily wastewater using lipase biological agents. Background Technology

[0002] Oily wastewater is generated in industrial production and daily life. This type of wastewater contains suspended grease, emulsified grease, and solid impurities. If discharged directly, it will form an oil film on the water surface, hindering oxygen exchange between the water and the air, leading to oxygen deprivation and death of aquatic organisms, and damaging the ecological environment. At the same time, the grease and impurities in the wastewater can also clog pipe networks and even pollute the soil, threatening human health and the stability of the ecosystem. Therefore, the effective treatment of oily wastewater has become an important issue in the field of environmental protection. At present, oily wastewater treatment often adopts a combination of biodegradation and physical filtration processes. Among them, lipase biological agents can efficiently catalyze the hydrolysis of grease into biodegradable fatty acids and glycerol, and have the advantages of being environmentally friendly and without secondary pollution. They are widely used in the biodegradation stage of oily wastewater. However, existing treatment equipment has the following problems:

[0003] After oily wastewater is biodegraded by lipase biological agents, it still needs to pass through filtration components to remove residual solid impurities and incompletely degraded flocculent matter in the water. The filtration components (such as filter screens) of existing equipment are prone to clogging after long-term use, requiring manual disassembly, cleaning or replacement, which is cumbersome and time-consuming, increasing labor costs and maintenance difficulty. Although some equipment is equipped with a flushing function, it requires an external backwash water source, resulting in high water consumption and cumbersome operation.

[0004] In existing equipment, the mixing of oily wastewater and lipase biological agents mostly relies on a simple stirring structure with rotating stirring blades, lacking an effective water circulation mechanism. The wastewater at the bottom of the treatment tank is difficult to effectively mix with the agent at the top, resulting in slow oil degradation rate and unsatisfactory degradation effect, which affects the subsequent treatment effect. Therefore, it is necessary to provide an integrated wastewater treatment equipment for oily wastewater degradation using lipase biological agents to solve the above technical problems. Summary of the Invention

[0011] Preferably, the reset component includes two horizontal fixing rods symmetrically arranged. One end of each horizontal fixing rod is fixedly connected to the side wall of the processing box, and the other end of each horizontal fixing rod is fixedly connected to a connecting block.

One end of the horizontal spring is fixedly connected to the side wall of the horizontal plate, and the other end of the horizontal spring is fixedly connected to the side wall of the connecting block.

[0012] Preferably, the mixing unit includes a stirring component and a flow guiding component. The stirring component includes a second motor, which is fixedly installed at the top of the processing tank. A vertical rotating shaft is rotatably connected to the top inner side of the processing tank.

[0013] Preferably, the flow guiding component includes a fixed crossbar, which is disposed above the U-shaped rod.

[0014] Preferably, a sewage pipe is connected to the bottom outlet of the treatment tank, and a valve is installed on the sewage pipe. A sewage inlet pipe and a chemical dosing pipe are fixedly connected to the top of the treatment tank and communicate with its interior. A drain pipe is fixedly connected to the side wall of the treatment tank and communicates with its interior. The drain pipe is located above the connecting pipe.

[0015] Preferably, the filter assembly includes a fixed frame, which is fixedly connected to the inside of the processing box, and a primary filter, a secondary filter, and a tertiary filter are fixedly connected to the inside of the fixed frame from bottom to top.

[0016] Compared with related technologies, the integrated wastewater treatment equipment for oily wastewater degradation using lipase biological agents provided by the present invention has the following beneficial effects:

[0017] In this invention, when the primary, secondary, and tertiary filters of the filtration assembly become clogged, the first motor in the flipping component drives the vertical threaded rod to rotate, causing the lifting frame to descend along the sliding groove of the fixed cylinder. The inclined guide groove of the lifting frame, in conjunction with the vertical guide groove and the eccentric wheel of the backwashing component, guides the horizontal shaft to flip the cover plate from a vertical to a horizontal position, so that the side of the cover plate with the water outlet hole is in contact with the top surface of the fixed frame. This allows for flushing posture adjustment without manual intervention, avoiding the tedious operation of manual disassembly, reducing maintenance difficulty and labor costs. During the flushing process, the wastewater directly utilizes the wastewater from the treatment tank. The filtered water is used as a rinsing water source. After the sewage discharged from the treatment tank is filtered by the filter components, a portion of water is reserved above the filter components and will not be discharged through the drain pipe. Under the action of gravity, the reserved water is transported sequentially through the connecting pipe, rotating pipe joint, and horizontal pipe to the hollow cavity of the cover plate. It is then sprayed through the water outlet to the primary filter screen, secondary filter screen, and tertiary filter screen, thereby flushing away residual impurities in the mesh. The impurities fall with the water to the bottom of the treatment tank and are discharged through the sewage pipe, reducing the risk of clogging of the primary, secondary, and tertiary filter screens, eliminating the need for frequent replacement of the filter components, and extending their service life.

[0018] During the descent of the lifting frame, in the initial stage, the horizontal part of the horizontal block blocks the push plate from moving downward. The lifting plate compresses the vertical spring to store elastic potential energy. As the lifting frame continues to descend, the squeezing block is guided by the first inclined part, pushing the push wheel. The L-shaped rod pulls the horizontal plate, causing the horizontal block to disengage from the push plate. At this time, the vertical spring releases its potential energy, pushing the push plate to move downward quickly, pressurizing the water below, accelerating the water flow through the connecting pipe and horizontal pipe into the hollow cavity, and finally spraying out from the water outlet. This enhances the rinsing force on the primary, secondary, and tertiary filters, improving the cleaning effect.

[0019] The horizontal spring of the reset component works in conjunction with the horizontal fixing rod to drive the horizontal stop block to reset, repositioning the push plate and preparing for the next backwash, thus ensuring the stable operation of the pressurization unit.

[0020] In this invention, the second motor of the stirring component drives the vertical shaft to rotate, which in turn drives the U-shaped rod and the stirring blades on both sides to rotate, thus horizontally stirring the wastewater and lipase bio-agent in the treatment tank and breaking up the water stratification. At the same time, the spiral blades of the guide component rotate synchronously with the vertical shaft, so that the wastewater in the lower part of the treatment tank is drawn in from the bottom of the vertical pipe and discharged to the upper area through the top of the vertical pipe, forming an upper and lower water circulation. This greatly increases the contact area and reaction efficiency between the lipase bio-agent and the oily wastewater, shortens the oil degradation time, and improves the reaction efficiency of the lipase bio-agent on the oily wastewater.

[0034] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0035] Example 1

[0036] Please refer to the following: Figures 1 to 5 An integrated wastewater treatment device for oily wastewater degradation using lipase biological agents includes a treatment tank 1, a treatment box 2 fixedly connected to one side of the treatment tank 1, a fixed cylinder 3 connected to the top of the treatment box 2, an inclined connecting pipe 9 connected to the outlet end of the treatment tank 1, one end of the inclined connecting pipe 9 passing through one side of the treatment box 2 and communicating with its interior, a valve installed on the inclined connecting pipe 9, a filter assembly 10 installed inside the treatment box 2, one end of the inclined connecting pipe 9 positioned below the filter assembly 10; a backwashing unit 4 and a pressurizing unit 5 installed inside the treatment box 2, and a mixing unit 6 installed inside the treatment tank 1; the backwashing unit 4 is used to rinse and clean the filter assembly 10; the pressurizing unit 5 is used to increase the water pressure when the backwashing unit 4 rinses the filter assembly 10; and the mixing unit 6 is used to accelerate the mixing and degradation of oily wastewater and lipase biological agents in the treatment tank 1.

[0037] In the above, the treatment tank 1 serves as the core container for the mixed degradation of oily wastewater and lipase biological agents, providing a stable space for the reaction. The treatment tank 2 receives the degraded wastewater and achieves solid-liquid separation through the internal filter assembly 10. The valve of the inclined connecting pipe 9 can precisely control the timing and flow rate of wastewater entering the treatment tank 2, avoiding the direct filtration of incompletely degraded wastewater and affecting the effect. The backwashing unit 4 is used to backwash and clean the filter assembly 10. The pressurization unit 5 increases the backwash water pressure to enhance the cleaning effect. The mixing unit 6 shortens the oil degradation time by optimizing the mixing efficiency.

[0038] Furthermore, the backwash unit 4 includes a backwash component 41 and a tilting component 42; the backwash component 41 includes a cover plate 411, the cover plate 411 having a hollow cavity 419 inside, a horizontal tube 412 communicating with the hollow cavity 419 fixedly connected to one side of the bottom end of the cover plate 411, and a horizontal shaft 415 fixedly connected to the other side of the bottom end of the cover plate 411. The horizontal shaft 415 and the horizontal tube 412 are coaxially arranged, and both the horizontal shaft 415 and the horizontal tube 412 are transversely and rotatably connected to the treatment box 2. The rotatable connection can be achieved through a sealed bearing. One end of the horizontal tube 412... After extending out of the treatment tank 2, a rotating pipe joint 413 is fixedly connected. The end of the rotating pipe joint 413 away from the horizontal pipe 412 is fixedly connected to a "C"-shaped connecting pipe 414. One end of the connecting pipe 414 is connected to the inside of the treatment tank 2. One end of the connecting pipe 414 is located above the filter assembly 10. One end of the horizontal shaft 415 extends out of the treatment tank 2 and is fixedly fitted with a connecting strip 416. One end of the connecting strip 416 is rotatably connected to an eccentric wheel 417. Several water outlet holes 418 that are connected to the hollow cavity 419 are evenly opened through one side of the cover plate 411.

[0039] In the above, the cover plate 411 of the backwashing component 41 forms a water channel with the horizontal pipe 412 and the connecting pipe 414 through the hollow cavity 419, which can introduce the filtered water in the treatment tank 2 and spray it out through the water outlet 418 to achieve targeted rinsing of the filter component 10. The rotating pipe joint 413 ensures that the horizontal pipe 412 is always connected to the connecting pipe 414 when it rotates. The eccentric wheel 417 provides a power transmission node for the cover plate 411 to flip. The overall structure does not require an external water source and utilizes the existing filtered water resources to reduce water consumption.

[0040] Furthermore, the tilting component 42 includes a lifting plate 421 and a lifting frame 423. The lifting plate 421 is slidably connected to the inner side of the fixed cylinder 3. A sliding groove 422 is transversely opened on one side of the fixed cylinder 3. One end of the lifting frame 423 passes through the sliding groove 422 and is fixedly connected to the side wall of the lifting plate 421. The side wall of the lifting frame 423 is slidably connected to the inner side wall of the sliding groove 422. A vertical guide groove 4231 and an oblique guide groove 4232 are transversely opened on the lifting frame 423. The top of 4232 is connected to the bottom of the vertical guide groove 4231. The eccentric wheel 417 is rolled in the inclined guide groove 4232. Both the vertical guide groove 4231 and the inclined guide groove 4232 are adapted to the eccentric wheel 417. The first motor 424 is fixedly installed on one side of the top of the fixed cylinder 3. The bottom of the first motor 424 is fixedly connected to the vertical threaded rod 425. The bottom of the vertical threaded rod 425 is rotatably connected to the top of the processing box 2. The lifting frame 423 is vertically threaded and sleeved on the outside of the vertical threaded rod 425.

[0041] In the above, the lifting plate 421 of the flipping component 42 is linked with the lifting frame 423. When the first motor 424 drives the vertical threaded rod 425 to rotate, it drives the lifting frame 423 to rise and fall stably along the sliding groove 422. The vertical guide groove 4231 and the inclined guide groove 4232, through cooperation with the eccentric wheel 417, convert the vertical movement of the lifting frame 423 into the rotational movement of the eccentric wheel 417, thereby driving the horizontal shaft 415 and the cover plate 411 to flip, realizing the automatic switching of the cover plate 411 from the vertical idle state to the horizontal rinsing state. There is no need to manually adjust the position of the cover plate 411, which improves the automation level of the equipment and reduces the amount of maintenance operations.

[0042] Furthermore, a sewage pipe 12 is connected to the bottom outlet of the treatment tank 2, and a valve is installed on the sewage pipe 12. A sewage inlet pipe 7 and a dosing pipe 8 connected to the top of the treatment tank 1 are fixedly connected to it. A drain pipe 11 connected to the side wall of the treatment tank 2 is fixedly connected to it. The drain pipe 11 is located above the connecting pipe 414, and the outlet end of the treatment tank 1 is located above the drain pipe 11.

[0043] As described above, the sewage pipe 12 can promptly discharge the impurities settled at the bottom of the treatment tank 2 and the pollutants generated by backwashing, avoiding accumulation that affects the efficiency of the filter assembly 10. The sewage inlet pipe 7 and the dosing pipe 8 respectively transport sewage and lipase biological agents to the treatment tank 1, ensuring that the reaction raw materials are supplied as needed. The drain pipe 11 is set above the connecting pipe 414, which can not only ensure that the filtered clean water is discharged in time, but also reserve some clean water above the filter assembly 10 as a backwash water source, realizing the recycling of water resources and reducing the operating cost of the equipment.

[0044] Example 2

[0045] For further details, please refer to [link / reference]. Figures 1 to 8Based on Embodiment 1, the pressurizing unit 5 includes a pressurizing component 51, a limiting component 52, and a resetting component 53. The pressurizing component 51 includes a push plate 511, which is slidably connected to the inner side of the processing box 2. A rubber sealing strip can be embedded in the surface of the push plate 511 that contacts the processing box 2 to improve the sealing performance. A vertical slide rod 512 is fixedly connected to the top of the push plate 511. The top of the vertical slide rod 512 passes through the lifting plate 421 and is fixedly connected to a circular plate 514. The vertical slide rod 512 is slidably connected to the lifting plate 421. A vertical spring 513 is sleeved on the outer side of the vertical slide rod 512. The top of the vertical spring 513 is fixedly connected to the bottom of the lifting plate 421, and the bottom of the vertical spring 513 is fixedly connected to the top of the push plate 511.

[0046] In the above, the pressurizing unit 5 provides high-pressure water flow to the backwashing unit 4 through the coordinated action of the pressurizing component 51, the limiting component 52, and the resetting component 53. The push plate 511 is connected to the inside of the treatment tank 2 in a sealed sliding connection, which not only ensures the sealing of the water in the treatment tank 2 and avoids water leakage and pressure loss during backwashing, but also ensures that the push plate 511 moves smoothly up and down to achieve pressurization. The vertical slide rod 512 connects the push plate 511 and the circular plate 514 on one hand, and slides with the lifting plate 421 on the other hand, providing guidance for the movement of the push plate 511 and preventing it from deviating during pressurization. The circular plate 514 can prevent the vertical slide rod 512 from moving. The vertical spring 513 is compressed and stores elastic potential energy when the lifting plate 421 descends and the push plate 511 is limited. After the limit is released, the potential energy is quickly released, pushing the push plate 511 to move down quickly. This applies pressure to the filtered water in the treatment tank 2, causing the water to flow at a higher speed through the connecting pipe 414 and the horizontal pipe 412 into the hollow cavity 419 of the cover plate 411, and finally spraying out from the water outlet 418. This enhances the flushing force on the primary filter screen 1001, the secondary filter screen 1002 and the tertiary filter screen 1003 in the filter assembly 10, effectively removing impurities that clog the mesh and improving the backwashing cleaning effect.

[0047] Furthermore, the limiting component 52 includes a horizontal plate 521, which is disposed on one side of the processing box 2. Two horizontal blocks 522 are symmetrically fixedly connected to both ends of the horizontal plate 521. The horizontal blocks 522 are laterally slidably connected to the processing box 2. The surfaces of the horizontal blocks 522 in contact with the processing box 2 are sealed. Rubber sealing strips can be embedded in the surfaces of the horizontal blocks 522 in contact with the processing box 2 to improve the sealing performance. A horizontal part 5221 is provided at the top of the horizontal block 522, and an inclined part 5222 is provided on the side of the horizontal block 522 away from the horizontal plate 521. Several equidistant parts along the length direction of the inclined part 5222 are rotatably connected to one side of the horizontal block 522. The guide wheel 523 and the horizontal stop block 522 are set at the bottom of the push plate 511. The top side of the push plate 511 is provided with a second inclined part 527 that corresponds to and matches the horizontal stop block 522. The second inclined part 527 and the inclined part 5222 are arranged parallel to each other. An L-shaped rod 524 is fixedly connected to one side of the horizontal plate 521. A push wheel 525 is rotatably connected to the L-shaped rod 524. An extrusion block 526 that corresponds to and matches the push wheel 525 is fixedly connected to the upper side of the lifting frame 423. The extrusion block 526 is provided with a vertical part 5261 and a first inclined part 5262. The bottom end of the vertical part 5261 and the top end of the first inclined part 5262 are provided with a rounded transition.

[0048] In the above, the horizontal stop 522 of the limiting component 52 initially limits the push plate 511 through the horizontal part 5221, so that it remains stationary when the lifting plate 421 descends, creating conditions for the compression and energy storage of the vertical spring 513. The inclined part 5222 is parallel to the second inclined part 527 of the push plate 511. In conjunction with the guide wheel 523, it can reduce friction when the push plate 511 returns to its original position and ensures that the horizontal stop 522 can smoothly avoid the impact. The first inclined part 5262 of the squeezing block 526 drives the horizontal plate 521 and the horizontal stop 522 to move through the push wheel 525 and the L-shaped rod 524, realizing the automatic release of the limit of the push plate 511, providing a trigger mechanism for pressurized flushing, eliminating the need for manual operation of the limit state and improving the response speed of the equipment.

[0049] Furthermore, the reset component 53 includes a horizontal fixing rod 531, two of which are symmetrically arranged. One end of the horizontal fixing rod 531 is fixedly connected to the side wall of the processing box 2, and the other end of the horizontal fixing rod 531 is fixedly connected to a connecting block 533. A horizontal plate 521 is laterally slidably sleeved on the outside of the two horizontal fixing rods 531. A horizontal spring 532 is sleeved on the outside of the horizontal fixing rod 531. One end of the horizontal spring 532 is fixedly connected to the side wall of the horizontal plate 521, and the other end of the horizontal spring 532 is fixedly connected to the side wall of the connecting block 533.

[0050] In the above, the horizontal fixing rod 531 of the reset component 53 plays a lateral guiding role for the horizontal plate 521 to prevent it from deviating when it moves. The horizontal spring 532 is squeezed and stores energy when the horizontal plate 521 drives the horizontal stop block 522 away from the push plate 511. When the squeezing block 526 separates from the push wheel 525, the horizontal spring 532 releases potential energy, pushes the horizontal plate 521 and the horizontal stop block 522 to reset, and limits the push plate 511 again, preparing for the pressurization and energy storage for the next backwash, ensuring that the pressurization unit 5 can work stably in cycles.

The stirring component 61 includes a second motor 611, which is fixedly installed at the top of the processing tank 1. A vertical rotating shaft 612 is rotatably connected to the top inner side of the processing tank 1. The top end of the vertical rotating shaft 612 passes through the processing tank 1 and is fixedly connected to the rotating end of the second motor 611. A U-shaped rod 613 is fixedly connected to the bottom end of the vertical rotating shaft 612. Several stirring blades 614 arranged at equal intervals are fixedly connected to both sides of the U-shaped rod 613.

[0053] In the above, the second motor 611 of the stirring component 61 provides power for mixing, and the vertical rotating shaft 612 transmits the power to the U-shaped rod 613. The stirring blades 614 on both sides of the U-shaped rod 613 can horizontally stir the sewage and preparation in different areas of the treatment tank 1, breaking up the water stratification.

[0054] Furthermore, the flow guiding component 62 includes a fixed crossbar 622, which is disposed above the U-shaped rod 613. Several fixed crossbars 622 are arranged in a circular array on the inner side of the processing tank 1. One end of several fixed crossbars 622 is fixedly connected to a vertical pipe 621. The other end of the fixed crossbar 622 is fixedly connected to the inner wall of the processing tank 1. The vertical pipe 621 is disposed inside the U-shaped groove of the U-shaped rod 613. A spiral blade 623 is disposed inside the vertical pipe 621. The spiral blade 623 is fixedly sleeved on the outside of the vertical rotating shaft 612.

[0055] In the above, the fixed crossbar 622 of the flow guiding component 62 stably fixes the vertical pipe 621 inside the treatment tank 1, ensuring that it does not shake when the spiral blade 623 rotates. The vertical pipe 621 is located inside the U-shaped groove of the U-shaped rod 613, complementing the stirring component 61. When the spiral blade 623 rotates with the vertical rotating shaft 612, it generates upward suction and thrust, which draws the sewage that is easy to settle in the lower part of the treatment tank 1 from the bottom end of the vertical pipe 621 and discharges it to the upper area through the top, forming an upper and lower water circulation. This solves the problem that the sewage in the lower part is difficult to mix with the preparation in the upper part in traditional stirring, greatly increases the contact area between the lipase biological agent and the oily sewage, and accelerates the degradation rate of oil.

[0056] Furthermore, the filter assembly 10 includes a fixing frame 1004, which is fixedly connected to the inside of the processing box 2. The fixing frame 1004 is fixedly connected from bottom to top to the inner side of the fixing frame 1004 to a primary filter 1001, a secondary filter 1002, and a tertiary filter 1003. The aperture of the filter screens of the primary filter 1001, the secondary filter 1002, and the tertiary filter 1003 decreases sequentially.

[0057] In the above description, the fixing frame 1004 of the filter assembly 10 provides stable support for each stage of the filter screen. At the same time, the fixing frame 1004 is sealed and fixed to the contact surface with the treatment box 2. The primary filter screen 1001, the secondary filter screen 1002, and the tertiary filter screen 1003 are arranged sequentially from bottom to top, which can realize a step-by-step filtration from coarse to fine. First, the primary filter screen 1001 intercepts large solid impurities, then the secondary filter screen 1002 filters larger solid impurities, and finally the tertiary filter screen 1003 filters fine residual solid impurities. Compared with single-layer or double-layer filter screens, three-stage filtration can significantly improve the clarity of the effluent and reduce the risk of blockage in the subsequent drain pipe 11. At the same time, the step-by-step design also reduces the clogging rate of single-stage filter screens.

[0058] Furthermore, the valves on the oblique connecting pipe 9, the drain pipe 11, and the sewage pipe 12 are all electric valves. The valves on the oblique connecting pipe 9, the drain pipe 11, and the sewage pipe 12, as well as the first motor 424 and the second motor 611, are all electrically connected to an external controller via wires.

[0059] In the above, the electric valves installed on the oblique connecting pipe 9, the drain pipe 11 and the sewage pipe 12, as well as the first motor 424 and the second motor 611, are all controlled by a controller.

[0060] The working principle of the integrated wastewater treatment equipment for oily wastewater degradation using lipase biological agents provided by this invention is as follows:

[0061] In use, first close the valve on the inclined connecting pipe 9, and transport the oily wastewater to be treated to the treatment tank 1 through the wastewater inlet pipe 7. Then, transport an appropriate amount of lipase biological agent to the treatment tank 1 through the dosing pipe 8. Start the second motor 611, which drives the vertical rotating shaft 612 to rotate. The vertical rotating shaft 612 drives the U-shaped rod 613 and the spiral blade 623 to rotate synchronously. The U-shaped rod 613 drives the stirring plate 614 to rotate synchronously. The stirring plate 614 rotates to stir and accelerate the mixing and degradation of the lipase biological agent and the oily wastewater. At the same time, when the spiral blade 623 rotates, it can draw the wastewater in the lower part of the inner side of the treatment tank 1 into the bottom of the vertical pipe 621 and discharge it from the top of the vertical pipe 621, further improving the mixing and degradation efficiency of the wastewater and the lipase biological agent.

[0062] After thorough mixing, turn off the second motor 611 and open the valve on the inclined connecting pipe 9. The wastewater, after being mixed and degraded with the lipase biological agent, enters the lower part of the filter assembly 10 in the treatment tank 2 under the action of gravity through the inclined connecting pipe 9. As the wastewater level in the treatment tank 2 rises, it passes through the filter assembly 10 and is filtered sequentially through the primary filter screen 1001, the secondary filter screen 1002, and the tertiary filter screen 1003 in the filter assembly 10. The filtered water is located above the filter assembly 10 in the treatment tank 2. Open the valve on the drain pipe 11 in advance. After the water level reaches the height of the drain pipe 11, the filtered water is discharged through the drain pipe 11. The filter assembly 10 filters and blocks the silt and solid impurities in the water below, and the sediment in the wastewater settles and accumulates at the bottom of the inner side of the treatment tank 2.

[0063] When the primary filter 1001, secondary filter 1002, and tertiary filter 1003 in the filter assembly 10 become clogged after prolonged filtration and require cleaning, the first motor 424 is started. The first motor 424 drives the vertical threaded rod 425 to rotate. With the threaded engagement between the lifting frame 423 and the vertical threaded rod 425, the rotation of the vertical threaded rod 425 causes the lifting frame 423 to move downward, and the lifting frame 423 drives the lifting plate 421 to move synchronously.

[0064] When the lifting frame 423 moves downward, it first guides the eccentric wheel 417 through the inclined guide groove 4232. The eccentric wheel 417 moves within the inclined guide groove 4232 and drives the connecting bar 416 to rotate the horizontal shaft 415 counterclockwise. Figure 6 As shown, the horizontal shaft 415 drives the cover plate 411 to rotate, and the cover plate 411 drives the horizontal tube 412 to rotate synchronously until the eccentric wheel 417 enters the vertical guide groove 4231 from the inclined guide groove 4232. At this time, the eccentric wheel 417 drives the cover plate 411 to adjust from the vertical state to the horizontal state, so that the side of the cover plate 411 with the water outlet hole 418 is pressed against the top surface of the fixed frame 1004, so that the water outlet hole 418 on the cover plate 411 faces the filter assembly 10. The setting of the rotating pipe joint 413 makes... While the horizontal pipe 412 rotates, it can maintain communication with the connecting pipe 414. When the eccentric wheel 417 enters the vertical guide groove 4231, it no longer drives the cover plate 411 to rotate, so that it can be stably maintained in a horizontal state. Since the drain pipe 11 is set above the connecting pipe 414, the liquid will be discharged through the drain pipe 11 after the liquid level reaches the height of the drain pipe 11. When the cover plate 411 is in a horizontal state, the filtered water above it that does not reach the height of the drain pipe 11 can be used as a backwash water source, without the need for external backwash water.

[0065] Initially, the push plate 511 rests against the horizontal part 5221 and is blocked by the horizontal part 5221 at the top of the horizontal stop block 522. At this time, the push plate 511 does not move downward, while the lifting plate 421 moves downward through the lifting frame 423 to compress the vertical spring 513. The vertical spring 513 is compressed and undergoes elastic deformation, opening the valve on the drain pipe 12 to discharge the sediment and impurities in the treatment tank 2. At the same time, after the cover plate 411 is stabilized in the horizontal state, the lifting frame 423 is controlled to continue moving downward until the squeezing block 526 contacts the push wheel 525. First, the first inclined part 5262 on the squeezing block 526 guides the push wheel 525, causing the push wheel 525 to move away from the treatment tank 2. The push wheel 525 pulls the L-shaped rod 524 to move the horizontal plate 521 away from the treatment tank 2. The horizontal plate 521 drives the two horizontal stops 522 to move away from the push plate 525. The plate 511 moves in the direction until the horizontal stop 522 is completely separated from the push plate 511. At this time, due to the elimination of the resistance of the horizontal stop 522, the elastic potential energy of the vertical spring 513 is released, thereby squeezing the push plate 511 to move downward. The vertical slide rod 512 slides vertically downward on the lifting plate 421 under the drive of the push plate 511. The push plate 511 applies pressure to the water below it, thereby accelerating the water to enter the connecting pipe 414, and then enters the hollow cavity 419 through the rotating pipe joint 413 and the horizontal pipe 412 in sequence, and finally flows out through the water outlet 418, washing the three-stage filter screen 1003, the two-stage filter screen 1002 and the one-stage filter screen 1001 in sequence, washing down the impurities in the mesh of the three-stage filter screen 1003, the two-stage filter screen 1002 and the one-stage filter screen 1001 and letting them fall to the bottom of the treatment box 2, and then being discharged through the drain pipe 12, thereby reducing the frequency of manual cleaning and replacement of the filter assembly 10.

[0066] After cleaning, close the valve on the drain pipe 12, reverse the rotation of the first motor 424, causing the vertical threaded rod 425 to flip, thus moving the lifting frame 423 upward. The lifting frame 423 moves the lifting plate 421 upward, the lifting plate 421 moves the circular plate 514 upward, and the circular plate 514 moves the vertical sliding rod 512 and the push plate 511 upward until the push plate 511 contacts the horizontal stop 522. The guide wheel 523 moves along the second inclined surface 527, guiding the horizontal stop 522 away from the push plate 511, so that the horizontal stop 522 does not obstruct the upward movement of the push plate 511, until the push plate 511 moves above the horizontal part 5221. At this time, the elastic potential energy of the horizontal spring 532 is released, so that the horizontal part 5221 of the horizontal stop 522 is again located at the bottom of the push plate 511 to block it, preparing for the next backwashing of the filter assembly 10.

[0067] At the same time, as the lifting frame 423 moves upward, the eccentric wheel 417 returns from the vertical guide groove 4231 to the inclined guide groove 4232, and enters from the top of the inclined guide groove 4232 to the bottom of the inclined guide groove 4232. Driven by the eccentric wheel 417, the horizontal shaft 415 drives the cover plate 411 to rotate in the opposite direction, so that the cover plate 411 returns from the horizontal state to the vertical state, thereby preventing the cover plate 411 from affecting the subsequent discharge of water filtered by the filter assembly 10.
