Description

Technical Field

[0001] This utility model relates to the field of filtration equipment technology, and in particular to a self-draining sludge and sewage filtration component and a disinfection tank filtration device. Background Technology

[0002] In the field of wastewater treatment, wastewater filtration is an essential step. For example, when discharging water into disinfection tanks, biological treatment tanks, or other facilities, wastewater needs to be filtered to remove suspended solids, impurities, or silt, and then allowed to settle. Existing technologies often rely on externally powered valve structures to discharge the sludge formed by sedimentation. For example, motors or air pumps are used to control the opening or closing of the discharge port; or sludge pumps are used to suck up the settled sludge. However, this reliance on external power leads to high energy consumption and increases the failure rate.

[0003] Based on this, the applicant is considering designing a self-draining sludge and wastewater filtration device that can reduce energy consumption. Utility Model Content

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is: how to provide a self-draining sludge and sewage filtration device that can reduce energy consumption.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A self-draining sludge and wastewater filtration assembly includes a filtration container disposed above a body of water and a floating mechanism that moves synchronously with the rise and fall of the water level.

[0007] A filtration section is provided on the side wall of the filter container, and a sedimentation tank is provided at the bottom of the filter container below the filtration section. A first drain outlet is provided on the bottom side of the filter container, connecting the sedimentation tank and the space below the filter container. An elastic sealing member corresponding to the first drain outlet is provided in the sedimentation tank. In its natural state, the elastic sealing member seals the first drain outlet.

[0008] The floating mechanism is provided with a lifting seat located below the filter container. The lifting seat is provided with a sewage discharge chamber. A collection hopper communicating with the top side of the sewage discharge chamber is provided. The collection hopper is located directly below the first sewage discharge port. When the floating mechanism rises, the collection hopper can drive the elastic sealing member to release the blockage of the first sewage discharge port.

[0009] The working principle and advantages of the self-draining sludge and wastewater filtration component in this technical solution are as follows:

[0010] During operation, the wastewater to be filtered is discharged into the filter container. The wastewater is filtered through the filter section on the side wall of the filter container and flows into the water body below. After filtration, suspended solids, impurities, or silt settle in the sedimentation tank at the bottom of the filter container. As the water level rises and falls, the floating mechanism rises and falls synchronously with the water level under the influence of buoyancy. When the floating mechanism rises, the collection hopper on its lifting seat drives the elastic sealing component in the sedimentation tank, causing the elastic sealing component to release the blockage of the first sewage outlet. The settled sludge is discharged from the first sewage outlet to the collection hopper under the action of its own gravity and water pressure, and then enters the sewage discharge chamber, realizing the automatic discharge of sludge. This self-draining sludge and wastewater filtration device is suitable for facilities where the water level changes, such as disinfection tanks, biological treatment tanks, or other facilities in wastewater treatment. Compared with existing technologies that rely on external power such as motors and air pumps to drive valves or use sludge pumps to suck up sludge, this device uses the rise and fall of the water level to drive the floating mechanism, thereby achieving automatic sludge discharge. It does not require additional energy consumption to drive the discharge device, effectively reducing energy consumption, which is conducive to energy conservation and emission reduction, and reduces the operating costs in the wastewater treatment process. At the same time, it reduces the risk of failure caused by complex mechanical components such as motors, air pumps, and sludge pumps in traditional solutions.

[0011] Furthermore, the elastic sealing component includes a hollow frame fixedly connected to the bottom side of the sedimentation tank. A spring is provided inside the hollow frame. One end of the spring is fixedly connected to the top side of the hollow frame, and the other end is fixedly connected to a sealing block for sealing the first sewage outlet.

[0012] Furthermore, the outer wall of the sealing block contacts the inner wall of the hollow frame to restrict the axial movement of the sealing block.

[0013] Furthermore, a top rod is fixedly connected inside the collection hopper, with the top end of the top rod extending out from the top side of the collection hopper and located directly below the sealing block.

[0014] Furthermore, a plurality of first sewage outlets, elastic sealing components and collection hoppers are provided accordingly; a second sewage outlet communicating with the outside is provided on the sewage discharge chamber.

[0015] Furthermore, it also includes a limiting structure for restricting the movement of the floating mechanism and limiting its axial lifting and lowering.

[0016] Furthermore, the filter container is annular and barrel-shaped, comprising an inner ring and an outer ring, with an annular cavity between the inner and outer rings, and a hollow cavity inside the inner ring.

[0017] Furthermore, the filtration section is disposed on the inner ring of the filter container, and the sedimentation tank is located at the bottom of the annular cavity of the filter container.

[0018] Furthermore, a sealing component capable of sealing the bottom of the hollow cavity is fixedly connected to the top side of the lifting seat.

[0019] The disinfection tank filtration device includes the self-draining sludge and sewage filtration assembly as described above. Attached Figure Description

[0039] Refer to together Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 as well as Figure 13 This embodiment provides a self-draining sludge and sewage filtration assembly, including a filtration container 100 disposed above a water body and a floating mechanism 200 that moves synchronously with the rise and fall of the water surface 11.

[0040] A filter section is provided on the side wall of the filter container 100. A sedimentation tank 120 is provided at the bottom of the filter container 100 below the filter section. A first drain outlet 144 is provided on the bottom side of the filter container 100, which connects the sedimentation tank 120 and the space below the filter container 100. An elastic sealing member 140 corresponding to the first drain outlet 144 is provided in the sedimentation tank 120. In its natural state, the elastic sealing member 140 seals the first drain outlet 144.

[0041] The floating mechanism 200 is provided with a lifting seat 230 located below the filter container 100. The lifting seat 230 is provided with a drain chamber 232. A collection hopper 234 communicating with the top side of the drain chamber 232 is provided. The collection hopper 234 is located directly below the first drain outlet 144. When the floating mechanism 200 rises, the collection hopper 234 can drive the elastic sealing member 140 to release the blockage of the first drain outlet 144.

[0042] In this embodiment, during operation, the wastewater to be filtered is discharged into the filter container 100. The wastewater is filtered through the filter section on the side wall of the filter container 100 and flows into the water body below. After filtration, suspended solids, impurities, or silt settle in the sedimentation tank 120 at the bottom of the filter container 100. As the water level 11 rises and falls, the floating mechanism 200 moves synchronously. When the floating mechanism 200 rises, the collection hopper 234 on its lifting seat 230 drives the elastic sealing member 140 in the sedimentation tank 120, causing the elastic sealing member 140 to release the seal on the first sewage outlet 144. Under the action of its own gravity and water pressure, the settled sludge is discharged from the first sewage outlet 144 to the collection hopper 234, and then enters the sewage discharge. The cavity 232 enables automatic sludge discharge. This self-draining sludge wastewater filtration device is suitable for facilities where the water level 11 changes, such as disinfection tanks 10, biological treatment tanks, or other facilities in wastewater treatment. Compared with existing technologies that rely on external power such as motors and air pumps to drive valves or use sludge pumps to suck up sludge, this device uses the rise and fall of the water level 11 to drive the floating mechanism 200 to move, thereby achieving automatic sludge discharge. It does not require additional energy consumption such as electricity to drive the discharge device, effectively reducing energy consumption, which is conducive to energy conservation and emission reduction, and reducing the operating cost in the wastewater treatment process. At the same time, it reduces the risk of failure caused by complex mechanical components such as motors, air pumps, and sludge pumps in traditional solutions.

[0043] Preferably, such as Figure 6 , Figure 7 and Figure 13As shown, the elastic sealing component 140 includes a hollow frame 141 fixedly connected to the bottom side of the sedimentation tank 120. A spring 142 is provided inside the hollow frame 141. One end of the spring 142 is fixedly connected to the top side of the hollow frame 141, and the other end is fixedly connected to a sealing block 143 for sealing the first sewage outlet 144. The hollow frame 141 provides installation space and connection points for the spring 142 and the sealing block 143 on it. The hollow frame 141 includes a disc and multiple vertical plates spaced apart on its bottom side. The space between the vertical plates allows sludge to pass through, ensuring the smooth discharge of sludge. The elastic force provided by the spring 142 can drive the sealing block 143 to seal the first sewage outlet 144 under natural conditions.

[0044] Preferably, such as Figure 6 , Figure 7 and Figure 13 As shown, the outer wall of the sealing block 143 contacts the inner wall of the hollow frame 141 to restrict the axial movement of the sealing block 143; the outer wall of the sealing block 143 contacts the inner wall of the hollow frame 141 to form a limiting fit, which restricts its movement in the axial direction (i.e., the up and down direction) during the movement of the sealing component, ensuring that the sealing block 143 can move smoothly along the predetermined axial path, so that it can accurately seal the first sewage outlet 144 or release the seal on the first sewage outlet 144, and avoid the sealing block 143 from tilting or getting stuck when moving axially.

[0045] Preferably, such as Figure 6 , Figure 7 and Figure 13 As shown, a top rod 235 is fixedly connected inside the collection hopper 234. The top of the top rod 235 extends out of the top side of the collection hopper 234 and is located directly below the sealing block 143. When the floating mechanism 200 rises, the collection hopper 234 rises accordingly, and the top of the top rod 235 contacts the bottom of the sealing block 143. As the collection hopper 234 rises further, the top rod 235 applies an upward force to the sealing block 143, thereby pushing the sealing block 143 to move upward and release it from the blockage of the first sewage outlet 144. In this way, the settled sludge can be smoothly discharged from the first sewage outlet 144 to the collection hopper 234 under the action of its own gravity and water pressure, and then enter the sewage discharge chamber 232.

[0046] Preferably, such as Figure 6 , Figure 7 , Figure 9 and Figure 10As shown, multiple first discharge ports 144, elastic sealing elements 140, and collection hoppers 234 are correspondingly provided; a second discharge port 233 communicating with the outside is provided on the discharge chamber 232; the provision of multiple first discharge ports 144, elastic sealing elements 140, and collection hoppers 234, and the provision of a second discharge port 233 communicating with the outside on the discharge chamber 232, allows sludge discharged from the multiple first discharge ports 144 to collect in the discharge chamber 232, and then be discharged to the outside through the second discharge port 233; when the floating mechanism 200 rises, each collection hopper 234... The collection hopper 234 drives the corresponding elastic sealing member 140 to release the blockage of the corresponding first sewage outlet 144, so that sludge settled at different positions can be discharged from multiple first sewage outlets 144 at the same time, enter their respective collection hoppers 234 and be collected into the sewage discharge chamber 232, and finally discharged to the outside through the second sewage outlet 233. The corresponding arrangement of multiple first sewage outlets 144, elastic sealing member 140 and collection hopper 234 can increase the efficiency of sludge discharge and collection, so that more sludge can be discharged in the same time, thus improving the efficiency of sludge discharge.

[0047] Preferably, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 8 , Figure 9 as well as Figure 10 As shown, the self-draining sludge and wastewater filtration assembly also includes a limiting structure. The limiting structure is used to restrict the movement of the floating mechanism 200 and restrict its axial lifting and lowering. The limiting structure restricts the movement of the floating mechanism 200 so that it can only move axially (i.e., vertically). This restriction ensures that when the water level 11 rises or falls, the floating mechanism 200 can accurately rise and fall in the predetermined axial direction without deviation or shaking. This ensures that the lifting seat 230, the collection hopper 234, and other components on the floating mechanism 200 can accurately cooperate with the elastic sealing member 140 and the first sewage outlet 144 at the bottom of the filter container 100. This ensures that when the floating mechanism 200 rises, the collection hopper 234 can accurately drive the elastic sealing member 140 to release the seal on the first sewage outlet 144, so as to achieve smooth discharge of sludge. Specifically, the limiting structure includes a limiting plate 152 fixedly installed on the outer wall of the filter container 100 and a driving rod 221 fixedly installed on the floating mechanism 200.

[0048] Preferably, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 8 , Figure 9As shown, the filter container 100 is an annular barrel shape, comprising an inner ring and an outer ring. The annular cavity between the inner and outer rings is a hollow cavity 170. When wastewater enters the filter container 100, it is filtered through the filtration section. The filtered water flows into the annular cavity and settles along the sedimentation tank 120 at the bottom of the annular cavity. The annular barrel structure of the filter container 100 greatly increases the filtration area, allowing more wastewater to be filtered simultaneously, improving filtration efficiency and meeting the needs of large-flow wastewater treatment.

[0049] Preferably, such as Figure 4 , Figure 5 , Figure 6 , Figure 8 As shown, the filtration section is set on the inner ring of the filter container 100, and the sedimentation tank 120 is located at the bottom of the annular cavity of the filter container 100. When the wastewater enters the filter container 100, it is first filtered through the filtration section on the inner ring to remove suspended solids, debris or silt from the wastewater. The filtered residual suspended solids and impurities gradually settle into the sedimentation tank 120 at the bottom of the annular cavity under the action of gravity, thus achieving the sedimentation function.

[0050] Preferably, such as Figure 4 , Figure 6 and Figure 10 As shown, the top side of the lifting seat 230 is fixedly connected to a sealing component 231 that can seal the bottom of the hollow cavity 170; when the liquid level 11 of the disinfection pool 10 rises to a certain height, the floating mechanism 200 can seal the bottom of the hollow cavity 170, temporarily blocking the drainage of the filter container 100 into the water. When the liquid level 11 drops, the drainage of the filter container 100 into the water is automatically restored without manual or other control system intervention; the dynamic adjustment of the water inlet function effectively prevents the water from overflowing due to excessive liquid level; specifically, the sealing component 231 is a barrel shape made of elastic material (such as rubber) to improve the sealing effect.

[0051] Disinfection pool filtration device:

[0052] like Figure 1 As shown, it includes the self-draining sludge and sewage filtration assembly as described above. The filter container 100 of the self-draining sludge and sewage filtration assembly is fixedly connected above the water body of the disinfection tank 10, and the floating mechanism 200 rises and falls synchronously with the rise and fall of the water level 11 of the disinfection tank 10.

[0053] Refer to together Figures 1-13 This embodiment provides a filtration device for the disinfection pool 10, and also includes a flow stabilizer 300 and a linkage lever 160;

[0054] The filter container 100 is positioned above the water in the disinfection tank 10, and the filter container 100 is equipped with a filter section for filtering the wastewater entering the disinfection tank 10.

[0055] The flow stabilizer 300 is floatingly installed inside the filter container 100, and the drainage entering the disinfection tank 10 is discharged into the filter container 100 through the flow stabilizer 300;

[0056] The floating mechanism 200 is located inside the disinfection tank 10 and moves synchronously with the rise and fall of the liquid level 11 in the disinfection tank 10.

[0057] The linkage lever 160 acts on the floating mechanism 200 and the flow stabilizer 300. When the liquid level 11 of the disinfection tank 10 rises, the floating mechanism 200 can drive the flow stabilizer 300 to move downward through the linkage lever 160 until the filter section of the filter container 100 is closed, thereby shutting off the drainage of the filter container 100 and switching the filter container 100 to a water storage state. When the liquid level 11 of the disinfection tank 10 falls, the flow stabilizer 300 moves upward with the buoyancy, opening the filter section of the filter container 100 to restore the drainage of the filter container 100.

[0058] In this embodiment, when the wastewater treated by the front-end treatment unit of the disinfection tank 10 is discharged into the disinfection tank 10, it is directly discharged into the flow stabilizer 300, and then discharged into the filter container 100 through the flow stabilizer 300. The filter container 100, which is set above the water body in the disinfection tank 10, filters the wastewater discharged into the disinfection tank 10 through its filtration section, filtering out impurities in the wastewater before it is discharged into the disinfection tank 10. The function of the flow stabilizer 300 is to make the wastewater discharged into the filter container 100 more stable during the discharge process, reduce water flow impact and interference, and allow the impurities filtered out in the filter container 100 to settle better in the filter container 100, thereby improving filtration efficiency. The floating mechanism 200 in the disinfection tank 10 moves synchronously with the rise and fall of the liquid level 11 in the disinfection tank 10. When the liquid level 11 in the disinfection tank 10 rises, the floating mechanism 200 moves in conjunction with the flow stabilizer 300. Lever 160 applies a downward force to flow stabilizer 300, driving it to move downwards until the filter section of filter container 100 is closed. At this time, filter container 100 switches to water storage mode and temporarily stops draining water into disinfection tank 10. When the liquid level 11 in disinfection tank 10 drops, lever 160 stops applying force to flow stabilizer 300, and flow stabilizer 300 moves upwards under buoyancy, opening the filter section of filter container 100. Filter container 100 then resumes draining water into disinfection tank 10. Through the filtration effect of filter container 100, impurities in wastewater are reduced, preventing impurities from shielding pathogens, improving the contact efficiency between disinfectant and pathogens, and reducing the risk of impurities in wastewater clogging the spray device of disinfection tank 10. This enhances the disinfection effect, reduces the risk of secondary pollution, and improves wastewater treatment efficiency. The floating mechanism 200, in conjunction with the linkage lever 160, can automatically adjust the water inlet status of the disinfection tank 10 according to the real-time changes in the liquid level 11. When the liquid level 11 in the disinfection tank 10 is too high, the water inlet is automatically shut off; when the liquid level 11 drops, the water inlet is automatically restored, without the need for manual intervention or other control systems. The dynamic adjustment of the water inlet function effectively prevents the disinfection tank 10 from overflowing due to excessive liquid level. Especially when the sewage treatment capacity fluctuates greatly due to factors such as peak water consumption and rainfall, it can respond promptly to changes in liquid level and ensure the normal operation of the disinfection tank 10.

[0059] Preferably, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 8 , Figure 9As shown, the outer wall of the filter container 100 is provided with an overflow trough 130, and the bottom of the overflow trough 130 is provided with a drain outlet 131. When the liquid level inside the filter container 100 is too high, the sewage will flow into the overflow trough 130 and be discharged through the drain outlet 131. The drain outlet 131 can be connected to the front-end treatment unit of the disinfection tank 10 for transportation (e.g., a sedimentation tank) to prevent unfiltered sewage from being discharged into the disinfection tank 10.

[0060] Preferably, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 8 , Figure 9 As shown, the filter container 100 is an annular barrel shape, which includes an inner ring and an outer ring. The annular cavity of the filter container 100 is located between the inner ring and the outer ring. A hollow cavity 170 is provided inside the inner ring of the filter container 100. The filter section is located on the side wall of the inner ring of the filter container 100. This is beneficial to increase the filtration area, improve the filtration efficiency, and make the filtration process more efficient.

[0061] Preferably, such as Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown in the figure, the flow stabilizer 300 is an annular barrel-shaped component located within the annular cavity of the filter container 100. It includes an inner ring and an outer ring, with the annular cavity between them. A floating ring 320 is provided on the outer wall of the outer ring of the flow stabilizer 300, and multiple annularly distributed water distribution ports 310 communicating with the annular cavity of the flow stabilizer 300 are provided. The water distribution ports 310 are located below the floating ring 320. The annular barrel-shaped structure of the flow stabilizer 300 allows it to correspond and cooperate with the annular cavity of the filter container 100, ensuring uniform distribution of wastewater during filtration and improving filtration efficiency. The annularly distributed water distribution... The inlet 310 allows wastewater to enter the annular cavity of the filter container 100 smoothly, further stabilizing the water flow, reducing the impact of the water flow on the annular cavity of the filter container 100, and improving the sedimentation effect of the annular cavity of the filter container 100; the floating ring 320 allows the flow stabilizer 300 to move synchronously with the rise and fall of the liquid level 11 in the annular cavity of the filter container; the water distribution port 310 is located below the floating ring 320, and after water is injected into the annular cavity of the filter container 100, the water distribution port 310 is always located below the liquid level 11 inside the annular cavity of the filter container 100 to buffer the water flow; specifically, when the flow stabilizer 300 descends to its lowest point, the water distribution port 310 is located below the filtration section.

[0062] Preferably, such as Figure 4 , Figure 5 , Figure 8 , Figure 11As shown, a convex ring 101 is provided on the inner wall of the inner ring of the filter container 100, and the filter part is located below the convex ring 101. A first abutting ring 351 is provided on the inner wall of the inner ring of the flow stabilizer 300, which abuts against the convex ring 101. A second abutting ring 352 is provided on the bottom side of the flow stabilizer 300, which abuts against the inner bottom side of the filter container 100. When the flow stabilizer 300 descends to its lowest point, the first abutting ring 351 abuts against the convex ring 101, and the second abutting ring 352 abuts against the inner bottom side of the annular cavity of the filter container 100, forming a closed annular cavity and closing the filter part. At this time, the filter container 100 switches to a water storage state and temporarily stops draining water into the disinfection tank 10. Specifically, the contact surfaces of the first abutting ring 351 and the convex ring 101 and the contact surfaces of the second abutting ring 352 and the inner bottom side of the annular cavity of the filter container 100 are elastic surfaces (such as rubber pads) to enhance the sealing effect.

[0063] Specifically, such as Figures 1-3 As shown, the front-end treatment unit of the disinfection pool 10 drains water to the flow stabilizer 300 through the water inlet pipe 12. More specifically, the water inlet pipe 12 is fixedly connected to the filter container 100.

[0064] Specifically, such as Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 8 , Figure 11 As shown, several limiting rods 151 are fixedly connected to the inner ring of the filter container 100, and a number of limiting blocks 340 that cooperate with the limiting rods 151 are fixedly connected to the inner side wall of the inner ring of the flow stabilizer 300. The cooperation between the limiting rods 151 and the limiting blocks 340 can limit the lifting trajectory of the flow stabilizer 300.

[0065] Preferably, such as Figure 4 , Figure 5 , Figure 6 , Figure 8 As shown, the filtration section includes a filter tube 110 fixedly connected to the inner ring side wall of the filter container 100. The filter tube 110 protrudes into the hollow cavity 170, and a filter plate 1724 is connected to the free end of the filter tube 110. The filter container 100 is filtered through the filter plate 1724 on the filter tube 110. The filter plate 1724 can be selected with a suitable filter medium according to the specific filtration requirements, such as a stainless steel filter screen or a multi-layer filter plate 1724.

[0066] Preferably, such as Figure 4 , Figure 5 , Figure 6 , Figure 8 , Figure 12As shown, the free end of the filter tube 110 faces the top of the filter container 100. A first mounting frame 111 is provided at the free end of the filter tube 110, and a first sealing gasket 112 is provided inside the first mounting frame 111. A top cover 172 is detachably connected to the top of the filter container 100. A second mounting frame 1722 corresponding to the first mounting frame 111 is connected to the top cover 172. A second sealing gasket 1723 is provided inside the second mounting frame 1722. The filter plate 1724 is detachably connected inside the first mounting frame 111. When the top cover 172 is connected to the filter container 100, the first mounting frame 111 and the second mounting frame 1722 are merged to seal the filter section between them. When installing the filter plate 1724, the filter plate 1724 is first connected to the second mounting frame 1722, and then the top cover 172 is connected to the filter container 100, so that the first mounting frame 111 and the second mounting frame 1722 are merged together. At this time, the filter plate 1724 is detachably connected inside the first mounting frame 111. The upper half of the filter plate 1724 is located inside the second mounting frame 1722, and the lower half extends into the first mounting frame 111, squeezing the first sealing gasket 112 and the second sealing gasket 1723 to seal the filter plate 1724 within the first mounting frame 111 and the second mounting frame 1722. The first sealing gasket 112 and the second sealing gasket 1723 effectively prevent sewage leakage, ensuring the sealing of the filtration process and preventing unfiltered sewage from flowing into the disinfection tank 10. When the filter plate 1724 needs to be replaced or maintained, the top cover 172 can be removed to take the filter plate 1724 out of the hollow cavity 170, and then the filter plate 1724 on the second mounting frame 1722 can be processed. There is no need to extend into the hollow cavity 170 to maintain or replace the filter plate 1724, which greatly reduces the difficulty of maintaining and replacing the filter plate 1724. Specifically, the second mounting frame 1722 is fixedly connected to the top cover 172 by multiple fixing rods 1721.

[0067] Preferably, Figure 1 , Figure 2 , Figure 3 , Figure 8 , Figure 9 , Figure 10As shown, the floating mechanism 200 includes a mounting frame 220 and a float 210 fixedly connected thereto. A linkage lever 160 is fixedly mounted on the filter container 100. The linkage lever has two actuating ends: one actuating end is located above the mounting frame 220, and the other actuating end is located above the flow stabilizer 300. When the liquid level 11 in the disinfection tank 10 rises, the float 210 drives the mounting frame 220 to rise. When the mounting frame 220 rises, it pushes the actuating end located above the mounting frame 220, driving the actuating end located below the flow stabilizer 300 to descend, thereby applying force to the flow stabilizer 300. A downward force is applied to drive the flow stabilizer 300 to move downward. Specifically, the filter container 100 is detachably connected to multiple linkage levers 160, the mounting bracket 220 is provided with multiple driving rods 221 that cooperate with the linkage levers 160, and the flow stabilizer 300 is provided with multiple support plates 330 that cooperate with the linkage levers 160. More specifically, multiple limiting plates 152 that restrict the driving rods 221 are detachably connected to the outer wall of the outer ring of the filter container 100. The cooperation between the limiting plates 152 and the driving rods 221 can limit the lifting trajectory of the floating mechanism 200.

[0068] Preferably, such as Figure 1 As shown, the bottom side of the filter container 100 is fixedly connected to a plurality of support columns 190 which are fixedly connected to the bottom side of the disinfection pool 10; the filter container 100 is fixedly installed in the disinfection pool 10 through the support columns 190.

[0069] Preferably, refer to together Figures 1-13 The disinfection pool 10 filtration device also includes a sewage discharge structure; the bottom of the aforementioned filter container 100 is provided with a sedimentation tank 120, and the sedimentation tank 120 has a first sewage discharge port 144. An elastic sealing element 140 is installed at the first sewage discharge port 144. Under normal conditions, the elastic sealing element 140 seals the first sewage discharge port 144; the sewage discharge structure also includes a lifting seat 230 set on the floating mechanism 200, a sewage discharge chamber 232 on the lifting seat 232 and a collection hopper 234 connected thereto, and a top rod 235 is fixedly installed inside the collection hopper 234. The floating mechanism 200 drives the lifting seat 230. When rising, it can drive the collecting hopper 234 to contact the bottom of the filter container 100, and cause the top rod 235 to extend into the first drain port 144, contacting the elastic sealing member 140 to block the first drain port 144, allowing the impurities settled in the sedimentation tank 120 to flow through the first drain port 144, through the collecting hopper 234 and into the drain chamber 232; specifically, the drain chamber 232 is provided with a second drain port 233, and the contents of the drain chamber 232 can be discharged outward through the second drain port 233. The second drain port 233 can be connected to the front-end treatment unit of the disinfection tank 10 for transportation (e.g., sedimentation tank).

[0070] A sedimentation tank 120 is provided at the bottom of the filter container 100 to collect impurities generated during the filtration process. The first drain port 144 of the sedimentation tank 120 is naturally sealed by the elastic sealing element 140. As the liquid level 11 of the disinfection tank 10 rises, the floating mechanism 200 can drive the lifting seat 230 to rise, automatically discharging the impurities settled at the bottom of the filter container 100, achieving a sewage discharge state, realizing an automated sewage discharge function without manual intervention, improving the automation level and operating efficiency of the device. The design of the collection hopper 234 and the sewage discharge chamber 232 ensures that impurities can be effectively collected and transported, reducing the accumulation of impurities in the filter container 100 and reducing the maintenance frequency of the filter device. The elastic sealing element 140 seals the first drain port 144 in the natural state to prevent impurities from flowing back into the disinfection tank 10 in the non-discharge state, ensuring the water quality of the disinfection tank 10. The collected impurities are transported back to the front-end treatment unit of the disinfection tank 10 through the second drain port 233, realizing the recycling treatment of impurities and improving the resource utilization rate of the entire sewage treatment system.

[0071] Specifically, the aforementioned elastic sealing component 140 includes a hollow frame 141 fixedly connected to the bottom side of the sedimentation tank 120. A spring 142 is installed inside the hollow frame 141. One end of the spring 142 is fixedly connected to the hollow frame 141, and the other end is fixedly connected to the sealing block 143. The sealing block 143 is correspondingly arranged with the first sewage outlet 144. An elastic surface is provided at the contact point between the collection hopper 234 and the filter container 100 to provide cushioning and prevent wear.

[0072] Preferably, refer to together Figures 1-13 The disinfection pool 10 filtration device also includes a backwash structure, which includes a top cover 172 and a sealing member 231 installed on the mounting base. The top cover 172 seals the top of the hollow cavity 170, and the mounting base is provided with a sealing member 231 to seal the bottom of the hollow cavity 170. When the floating mechanism 200 drives the lifting seat 230 to rise, it can drive the sealing member 231 to seal the bottom of the hollow cavity 170, so that a closed backwash chamber is formed inside the hollow cavity 170. Then, backwash liquid is injected into the backwash chamber to backwash the filter section (filter plate 1724) inside the hollow cavity 170.

[0073] The top cover 172 of the filtration device in the disinfection tank 10 seals the top of the hollow cavity 170, and a sealing element 231 is provided on the mounting base. Under normal filtration conditions, the bottom of the hollow cavity 170 is open, allowing wastewater filtered by the filtration section to be discharged into the disinfection tank 10. When the floating mechanism 200 drives the lifting seat 230 to rise until the sealing element 231 seals the bottom of the hollow cavity 170, backwash liquid (using clean water, water in the disinfection tank 10, or other flushing liquid) is injected. As the backwash liquid is injected, the pressure in the backwash cavity gradually increases. The increased pressure causes the backwash liquid to backwash from the outside of the filtration section (filter plate 1724) to the inside. The water flow reverses through the filtration section, flushing down impurities and particles attached to the filter medium, thereby cleaning the filtration section. More specifically, the sealing element 231 is a barrel shape made of an elastic material (e.g., rubber) to improve the sealing effect. The bottom side of the top cover 172 can be provided with a protruding structure that extends into the hollow cavity 170 to reduce the amount of backwash liquid used.

[0074] Specifically, during the backwashing process, the disinfection and filtration device is in a sludge discharge state. Impurities discharged during backwashing flow into the sedimentation tank 120 along with the backwash liquid. Afterward, these impurities can be discharged from the filter container 100 through the sludge discharge structure, as described above. The discharge occurs through the first sludge discharge port 144, the collection hopper 234, and the sludge discharge chamber 232, finally exiting through the second sludge discharge port 233 to the front-end treatment unit of the disinfection tank 10. More specifically, when the flow stabilizer 300 descends to its lowest point, the first contact ring 351 contacts the convex ring 101, and the second contact ring 352 contacts the annular cavity of the filter container 100. When the inner bottom side abuts to form a closed ring cavity, backwash liquid is injected into the backwash cavity for backwashing. During backwashing, the backwash liquid enters the closed ring cavity through the filter section, flushes the sedimentation tank 120 inside the closed ring, and passes through the first drain port 144, collection hopper 234, and drain chamber 232, and is finally discharged to the front-end treatment unit of the disinfection tank 10 through the second drain port 233. While backwashing the filter plate 1724, the sedimentation tank 120 is also flushed. Regular backwashing reduces the risk of filter blockage and impurity accumulation in the sedimentation tank 120, and reduces maintenance frequency and cost.

[0075] Specifically, the top of the filter container 100 is provided with a water inlet 171 that communicates with the hollow cavity 170. The water inlet 171 is connected to a water pump or other water supply equipment, and the water supply equipment injects water into the hollow cavity 170 through the water inlet 171.

[0076] Specifically, the disinfection tank 10 filter device is equipped with a detection unit (not shown in the figure) that can detect whether the disinfection filter device is in a sewage discharge state (top cover 172 opens the elastic sealing member 140), a backwash chamber state (closing member 231 closes the bottom of the hollow cavity 170), or a closed ring chamber state (flow stabilizer 300 descends to the lowest point). The detection unit can use a contact sensor in the prior art, for example, the detection unit is placed against the filter container 100. The disinfection tank 10 filter device also includes a control unit that is communicatively connected to the detection unit. The control unit can turn the above-mentioned water supply equipment on or off through the detection signal of the detection unit.

[0077] Specifically, the filtration device of the disinfection pool 10 also includes an electromagnet 180, which is fixedly connected to the bottom of the filter container 100. When the electromagnet 180 is activated, it can magnetically attract the top of the lifting seat 230, allowing the filtration device to maintain a stable state of sewage discharge, forming a backwash chamber and a closed loop chamber. Even if the liquid level 11 fluctuates, the magnetic attraction of the electromagnet 180 can ensure the stability of the position of the lifting seat 230 and the sealing component 231, improving the backwash and sewage discharge effect. Of course, the activation and deactivation of the electromagnet 180 can be controlled by the control unit. The control unit can control the electromagnet 180 and the water supply equipment according to preset time, frequency, conditions or detection signals from the inspection unit to achieve automated control. Of course, it can also be controlled manually.

[0078] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
