Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and in particular to a wastewater treatment device with multi-stage filtration and high purification capabilities. Background Technology

[0002] Multistage filtration is the mainstream process for wastewater purification. As the core filtration component of wastewater treatment devices, the filter plate's ability to pass through pollutants, resist adhesion, and self-clean directly determines the wastewater purification efficiency and the continuous operating time of the equipment. However, traditional filtration stations mostly use a fixed single filter plate structure, which cannot achieve alternating operation of two plates. Impurities and sludge on the surface of the filter plate are easily compacted and adhered, clogging the filter pores. Cleaning by static water rinsing alone is ineffective, requiring shutdown for disassembly and cleaning of impurities, resulting in poor treatment continuity. At the same time, the filter plate switching structure and the cleaning structure are independent of each other, and the switching of filtration stations cannot trigger the cleaning action in conjunction with the filtration station. A separate cleaning drive mechanism is required, resulting in redundant equipment structure and high operation and maintenance costs. Furthermore, it cannot simultaneously handle both high-flow filtration with dual plates and single-plate alternating operation and maintenance filtration. The filter plates are prone to clogging, require frequent cleaning, and involve frequent downtime for maintenance, making it difficult to meet the needs of uninterrupted, high-purity, and long-term stable multistage filtration treatment of wastewater.

[0003] To address the above problems, this invention proposes a high-purification wastewater treatment device with multi-stage filtration function. Summary of the Invention

[0004] The purpose of this invention is to solve the problems of traditional filtration stations where impurities and sludge on the surface of the filter plate are easily compacted and adhered to block the filter holes. The cleaning effect is poor when relying solely on static water rinsing, and the machine needs to be stopped to disassemble and clean the impurities, resulting in poor processing continuity. At the same time, the filter plate switching structure and the cleaning structure are independent of each other, and the filtration station switching cannot be linked to trigger the cleaning action, requiring a separate cleaning drive mechanism. Therefore, this invention proposes a multi-stage filtration function for high-purification wastewater treatment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A high-purification wastewater treatment device with multi-stage filtration function includes a wastewater treatment mechanism, wherein the wastewater treatment mechanism is provided with a multi-stage wastewater filtration mechanism. The wastewater multi-stage filtration mechanism includes a drive assembly and multiple sets of filter assemblies. Each set of filter assemblies consists of two assemblies. Two vibration assemblies are arranged between the two filter assemblies. A cleaning assembly is arranged above the filter assemblies. A movable plate is arranged on one side of the filter assemblies. A guide port is provided on the movable plate. The drive assembly, in conjunction with the guide port, can drive two adjacent filter assemblies in the same set to move alternately. The wastewater treatment unit includes a treatment tank, on which a sludge suction component is installed, and the sludge suction component is connected to multiple cleaning components.

[0006] Preferably, a sludge inlet is provided at the top of the treatment box, one end of which extends to the top of the filter assembly, and a filter layer is provided at the bottom of the inner cavity of the treatment box.

[0007] Preferably, the sludge suction assembly includes a sludge suction pump, which is installed on the treatment tank and connected to a multi-port pipe. Multiple pipes extending into the treatment tank from the multi-port pipe are equipped with toothed valves.

[0008] Preferably, the filter assembly includes a fixed outer frame and a filter frame. The fixed outer frame is fixedly connected to a movable plate. A toothed plate is fixedly connected to the fixed outer frame near the movable plate. The toothed plate can engage with a toothed valve.

[0009] Preferably, the filter frame is disposed in a fixed outer frame, and the mesh size of the multiple filter frames decreases sequentially from top to bottom. A connecting groove is provided on both sides of the filter frame, and a connecting strip is provided in the connecting groove. The connecting strip is fixedly connected to the inner wall of the fixed outer frame. A flexible layer is fixedly connected to both side walls of the fixed outer frame, and one side of the flexible layer is fixedly connected to the filter frame.

[0010] Preferably, the fixed outer frame has sliding grooves on both sides, the sliding grooves are slidably connected to the guide strips, and the guide strips are fixedly connected to the inner wall of the processing box.

[0011] Preferably, the cleaning assembly includes a suction head, which is connected to a multi-port pipe. The portion of the multi-port pipe near the suction head is configured as a flexible hose. A cleaning brush is provided below the suction head and overlaps with the filter frame. Two movable rods are fixedly connected above the suction head. The movable rods are mounted through a fixed bracket. A return spring is fixedly connected between the fixed bracket and the top of the movable rods. The fixed bracket is fixedly connected to the inner wall of the treatment box.

[0012] Preferably, the drive assembly includes two electric push rods, which are fixedly mounted on the processing box. One end of each electric push rod is fixedly connected to both ends of a connecting shaft. The connecting shaft is provided with multiple outer rollers, which slide in the guide opening.

[0013] Preferably, each of the guide ports includes a straight port and an oblique port connected to the straight port, and the oblique ports of the two guide ports corresponding to the two filter components in the same group have opposite inclination directions.

[0014] Preferably, the vibration assembly includes a drive shaft, which is rotatably mounted on a drive frame via bearings. Two drive frames are respectively fixedly connected to two fixed outer frames. A cam structure and a gear are respectively fixedly connected to both ends of the drive shaft. The gear meshes with a rack, and two racks are respectively fixedly connected to two fixed outer frames. The cam structure overlaps with a roller, and two rollers are respectively set on two filter frames.

[0015] Compared with the prior art, the present invention provides a wastewater treatment device with multi-stage filtration function and high purification, which has the following beneficial effects: 1. This multi-stage filtration high-purification wastewater treatment device can increase the wastewater filtration area and improve the efficiency of multi-stage wastewater treatment by using two filter frames in a single set simultaneously. When maintenance is required, the drive component and guide port can work together to alternately switch the filter frames to operate independently, ensuring uninterrupted operation. When the filter frames move, they can be linked with the vibration component to make the filter frames vibrate. The vibration breaks up and shakes off the sludge and impurities attached to the pores and surface of the filter frames, reducing the compaction and adhesion of impurities inside the filter holes, thereby reducing the probability of filter frame clogging. Furthermore, the linear motion of the filter frames is used as a power source to drive the vibration component, which can reduce costs.

[0016] 2. This multi-stage filtration high-purification sewage treatment device uses the movement of the filter frame while the cleaning component remains in a fixed position. This allows the cleaning component to work in conjunction with the sludge suction component to achieve the purpose of sludge suction. There is no need to add a displacement device to drive the sludge suction head. Moreover, compared with traditional vibration cleaning, this device can deeply clean stubborn impurities embedded inside the filter frame pores, achieving deep cleaning of the filter frame. At the same time, the cleaning operation and the filter frame switching operation are synchronized, eliminating the need to start and stop the cleaning equipment separately. The cleaning process does not require extra working time and can quickly complete the regeneration of the filter frame.

[0017] 3. This multi-stage filtration high-purification wastewater treatment device allows for the switching of two filter components through the cooperation of the drive component and guide port. The switching process can be linked with the vibration component to achieve a vibration effect. Vibration can remove loose impurities on the surface of the filter components in advance, reducing the workload of subsequent sludge suction, improving sludge suction efficiency, and preventing impurities from hardening and reducing the workload of the sludge suction component. The movement of the filter components allows the sludge suction component to thoroughly clean the surface sludge. At the same time, the cleaning effect of the cleaning component can improve the sludge suction efficiency. Furthermore, it can deeply remove embedded impurities that cannot be removed by vibration, completely restoring the water permeability and filtration performance of the filter components. This device combines the functions of high-flow filtration, non-stop alternating operation and maintenance, and dual-layer self-cleaning capability. It solves the problems of easy clogging of filter plates, need for shutdown cleaning, unstable purification, and cumbersome operation and maintenance in traditional wastewater treatment, thereby improving the purification efficiency of multi-stage filtration devices.

Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0022] Example 1: Refer to Figures 1-6 and Figures 8-10 A high-purification wastewater treatment device with multi-stage filtration function includes a wastewater treatment unit 100, in which a multi-stage wastewater filtration unit 200 is provided. The multi-stage wastewater filtration mechanism 200 includes a drive assembly 202 and multiple sets of filtration assemblies 201. The drive assembly 202 includes two electric push rods 2021, which are fixedly mounted on the treatment tank 101. One end of each electric push rod 2021 is fixedly connected to both ends of a connecting shaft 2022. Multiple outer rollers 2023 are mounted on the connecting shaft 2022. The outer rollers 2023 slide in guide ports 205. Each guide port 205 includes a straight port and an oblique port communicating with the straight port. The two guide ports 205 corresponding to the two filter components 201 have opposite inclination directions. Through these two oppositely positioned oblique ports, the electric push rod 2021 extends and retracts, controlling the outer roller 2023 to alternately enter the two oblique ports. This allows for alternating control of the switching action of the two filter frames 2013. One end of the straight port extends beyond the oblique port, ensuring the outer roller 2023 has sufficient sliding distance within the oblique ports to avoid affecting the switching of the filter frames 2013. The number of filter components 201 in each group is... Two vibration components 203 are arranged between the two filter components 201. Each vibration component 203 includes a drive shaft 2035, which is rotatably mounted on a drive frame 2033 via bearings. The two drive frames 2033 are respectively fixedly connected to two fixed outer frames 2011. A cam structure 2032 and a gear 2036 are respectively fixedly connected to both ends of the drive shaft 2035. The cam structure 2032 is shaped like a petal to increase the number of contacts with the roller 2031, further enhancing... The vibration frequency of the filter frame 2013 is increased. The gear 2036 meshes with the rack 2034. Through the transmission between the rack 2034 and the gear 2036, the transmission shaft 2035 can be driven to rotate the cam structure 2032. The cam structure 2032 and the roller 2031 are squeezed to realize the vibration of the filter frame 2013. The two racks 2034 are fixedly connected to the two fixed outer frames 2011 respectively. The cam structure 2032 overlaps with the roller 2031. The two rollers 2031 are respectively set on the two filter frames 2013. A cleaning component 103 is disposed above the filter assembly 201, and a movable plate 204 is disposed on one side of the filter assembly 201. The movable plate 204 has a guide port 205. The drive component 202, in conjunction with the guide port 205, can drive two adjacent filter assemblies 201 in the same group to move alternately. The filter assembly 201 includes a fixed outer frame 2011 and a filter frame 2013. The fixed outer frame 2011 is fixedly connected to the movable plate 204, and a toothed plate 206 is fixedly connected to the fixed outer frame 2011 near the movable plate 204. The toothed plate 206 can engage with the toothed valve 1023. The filter frame 2013 is located in the fixed outer frame 2011, and the mesh size of multiple filter frames 2013 decreases sequentially from top to bottom. By achieving multi-stage filtration of wastewater through the sequential decrease in mesh size of each filter frame 2013, multi-stage filtration can be achieved. Furthermore, there is a slight difference in mesh size between the two filter frames 2013 in each filter assembly 201, and the mesh size still decreases sequentially from top to bottom. This ensures that multi-stage filtration is maintained even when two filter frames 2013 are used simultaneously. Both sides of the filter frame 2013 are provided with connecting grooves 2014, and connecting strips 2015 are provided in the connecting grooves 2014. The connecting strips 2015 engage with the connecting grooves 2014 to maintain the stability of the filter frame 2013 and allow the filter frame 2013 to slide smoothly. The connecting strips 2015 are fixedly connected to the inner wall of the fixed outer frame 2011. Flexible layers 2012 are fixedly connected to both sides of the fixed outer frame 2011. The flexible layer 2012 is a rubber layer, a silicone layer, or an elastic sealing layer, so that the flexible layer 2012 can generate a certain shape when pressed. The change ensures that the filter frame 2013 has a certain amount of movable space, allowing the filter frame 2013 to vibrate smoothly. One side of the flexible layer 2012 is fixedly connected to the filter frame 2013. Both sides of the fixed outer frame 2011 are provided with sliding grooves 2017, which are slidably connected to the guide bar 2016. The fixed outer frame 2011 can slide smoothly on the guide bar 2016 through the sliding grooves 2017, thereby ensuring that the filter frame 2013 can switch smoothly. The guide bar 2016 is fixedly connected to the inner wall of the processing box 101. The wastewater treatment unit 100 includes a treatment tank 101. An inlet 104 is provided on the top of the treatment tank 101, and one end of the inlet 104 extends to the top of the filter assembly 201. A filter layer is provided at the bottom of the inner cavity of the treatment tank 101. The mesh of the filter layer is smaller than that of the filter frame 2013 above, so that the filter layer can perform the final filtration treatment on the wastewater. A drain outlet is provided at the bottom of the treatment tank 101 so that the filtered wastewater can be discharged. A sludge suction assembly 102 is provided on the treatment tank 101. The sludge suction assembly 102 is connected to multiple cleaning assemblies 103. The cleaning assemblies 103 are used to brush and clean the surface of the filter frame 2013. The sludge suction assembly 102 is used to suck up sludge and impurities from the surface and pores of the filter frame 2013 through the sludge suction head 1031 in the cleaning assembly 103.

[0023] In this embodiment: by using two filter frames 2013 in a single set simultaneously, the wastewater filtration area can be increased, improving the efficiency of multi-stage wastewater treatment. When maintenance is required, the electric push rod 2021 controls the movement of the connecting shaft 2022, which in turn drives the outer roller 2023 to move. The outer roller 2023 enters the inclined opening of the guide port 205, thereby driving the movable plate 204 and the fixed outer frame 2011 to move. This allows the filter frames 2013 to alternately switch between independent operation, ensuring uninterrupted operation. Furthermore, when the filter frames 2013 move, the teeth... The rod 2034 is driven by the gear 2036. The gear 2036 drives the drive shaft 2035 to rotate. The drive shaft 2035 drives the cam structure 2032 and the roller 2031 to produce a reciprocating squeezing action, so that the roller 2031 can drive the filter frame 2013 to vibrate. By vibrating, the sludge and impurities attached to the pores and surface of the filter frame 2013 are broken up and shaken off, reducing the compaction and adhesion of impurities inside the filter holes, thereby reducing the probability of clogging of the filter frame 2013. Furthermore, the linear motion of the filter frame 2013 is used as a power source to drive the vibration component 203, which can reduce costs.

[0024] Example 2: Refer to Figures 3-4 and Figure 7 A high-purification wastewater treatment device with multi-stage filtration function includes a sludge suction component 102, which includes a sludge suction pump 1021. The sludge suction pump 1021 is installed on the treatment tank 101 and is connected to a multi-port pipe 1022. Multiple pipes extending from the multi-port pipe 1022 into the treatment tank 101 are equipped with toothed valves 1023. Each toothed valve 1023 consists of a valve and a transmission tooth. The valve shaft is connected to the transmission tooth, so that the toothed plate 206 can move and drive the transmission tooth, thereby controlling the valve to open the corresponding pipe of the multi-port pipe 1022 for easy sludge suction. After the toothed plate 206 is reset, it can automatically close the pipe of the multi-port pipe 1022. The cleaning assembly 103 includes a suction head 1031, which is connected to a multi-port pipe 1022. The portion of the multi-port pipe 1022 near the suction head 1031 is a flexible hose. When the filter frame 2013 moves, the return spring 1033 keeps the cleaning brush 1034 in close contact with the surface of the filter frame 2013, allowing the cleaning brush 1034 to clean the filter frame 2013. 13 serves a cleaning function. A cleaning brush 1034 is provided below the suction head 1031. The cleaning brush 1034 overlaps with the filter frame 2013. Two movable rods 1035 are fixedly connected above the suction head 1031. The movable rods 1035 are installed through a fixed bracket 1032. A return spring 1033 is fixedly connected between the fixed bracket 1032 and the top of the movable rods 1035. The fixed bracket 1032 is fixedly connected to the inner wall of the treatment box 101.

[0025] In this embodiment: the filter frame 2013 moves while the cleaning component 103 remains in a fixed position, allowing the cleaning brush 1034 to clean the surface of the filter frame 2013. At the same time, the sludge pump 1021 can perform a suction action through the sludge suction head 1031, eliminating the need for additional displacement equipment to drive the sludge suction head 1031. Moreover, compared to traditional vibration cleaning, this device can deeply clean stubborn impurities embedded inside the filter holes of the filter frame 2013, achieving deep cleaning of the filter frame 2013. Furthermore, the cleaning operation is synchronized with the filter frame 2013 switching operation, eliminating the need to start and stop the cleaning equipment separately. The cleaning process does not require additional working time and can quickly complete the regeneration of the filter frame 2013.

[0026] Example 3: Refer to Figures 1-5 A high-purification wastewater treatment device with multi-stage filtration function includes a multi-stage wastewater filtration mechanism 200. The multi-stage wastewater filtration mechanism 200 includes a drive component 202 and multiple sets of filter components 201. Each set of filter components 201 consists of two components. Two vibration components 203 are arranged between the two filter components 201. A cleaning component 103 is arranged above the filter components 201. A movable plate 204 is arranged on one side of the filter components 201. A guide port 205 is opened on the movable plate 204. The drive component 202, in conjunction with the guide port 205, can drive two adjacent filter components 201 in the same set to move alternately. The wastewater treatment unit 100 includes a treatment tank 101, on which a sludge suction component 102 is provided, and the sludge suction component 102 is connected to a plurality of cleaning components 103.

[0027] In this embodiment: the drive component 202, in conjunction with the guide port 205, allows for the alternating movement of two filter components 201. During the switching process, the vibration component 203 is linked to achieve a vibration effect. This vibration helps to pre-detach loose impurities from the surface of the filter component 201, reducing the workload for subsequent sludge suction, improving suction efficiency, preventing impurities from hardening and solidifying, and reducing the workload of the suction component 102. The movement of the filter component 201 allows the suction component 102 to thoroughly clean the surface sludge. Combined with the cleaning effect of the cleaning component 103, this improves suction efficiency and allows for the deep removal of embedded impurities that vibration cannot remove, completely restoring the water-permeable filtration performance of the filter component 201. This device combines high-flow filtration, non-stop alternating operation and maintenance, and dual-layer self-cleaning capabilities, solving the problems of easy clogging of traditional wastewater treatment filter plates, the need for shutdown for cleaning, unstable purification, and cumbersome maintenance. This improves the purification efficiency of multi-stage filtration devices.

[0028] Working principle: During sewage filtration, sewage is discharged through the inlet 104 to the uppermost filter frame 2013 for preliminary filtration. After filtration, it passes through each filter frame 2013 below for multi-stage filtration. The filtered sewage passes through the filter layer and is discharged through the sewage outlet below the treatment tank 101. When switching filter frames 2013, the electric push rod 2021 drives the connecting shaft 2022 to move. The connecting shaft 2022 drives the outer roller 2023 into the inclined opening of the guide port 205. The inclined setting of the inclined opening causes the outer roller 2023 to drive the movable plate 204 to move. The movable plate 204 drives the lower filter frame 2013 of each group of filter frames 2013 to move, causing the rack 2034 to drive the gear 2036. The gear 2036 drives the transmission shaft 2035 to rotate. The transmission shaft 2035 drives the cam structure 2032 to rotate. The convex surface of the cam structure 2032 reciprocates. The pressure roller 2031 reciprocates to drive the filter frame 2013 to vibrate, loosening the sludge on the surface of the filter frame 2013. At the same time, the cleaning brush 1034 cleans the surface of the filter frame 2013. When the toothed plate 206 and the toothed valve 1023 are driven, the multi-port pipe 1022 can be opened, allowing the sludge pump 1021 to perform sludge suction through the sludge suction head 1031. When it is necessary to switch the upper filter frame 2013, the electric push rod 2021 retracts, allowing the outer roller 2023 to enter the inclined opening of the upper guide port 205, thereby driving the upper filter frame 2013 to perform the switching operation.

[0029] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
