[0002] Wastewater treatment equipment, as a key component in wastewater treatment, is constantly evolving to meet increasingly stringent environmental protection requirements. Modern wastewater treatment systems combine physical, chemical, and biological methods. Physical methods such as screen interception and sedimentation separation remove large particulate impurities like suspended solids and floating matter from wastewater; chemical reactions such as coagulation, neutralization, and oxidation-reduction effectively degrade toxic and harmful substances in wastewater; and the metabolic activity of microorganisms transforms organic matter in wastewater into harmless substances, thus achieving wastewater purification.

[0003] However, existing wastewater treatment equipment is prone to clogging during operation. The clogging problem not only seriously affects the normal operation of the wastewater treatment equipment, making it difficult for water to flow and reducing treatment efficiency, but may also aggravate equipment wear and increase maintenance costs.

[0049] First, those skilled in the art should understand that these embodiments are merely for explaining the technical principles of this application and are not intended to limit the scope of protection of this application. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.

[0050] Secondly, it should be noted that, in the description of the embodiments of this application, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.

[0051] Furthermore, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first and second features are in direct contact, or that they are in indirect contact through an intermediate medium. Moreover, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0052] As described in the background art, wastewater treatment devices in related technologies are prone to clogging during operation. Research by the inventors has revealed that this problem arises because waste material easily accumulates at the filter location and cannot be cleaned in time, leading to clogging of the wastewater treatment device.

[0053] To address the aforementioned technical problems, this application provides a wastewater treatment device, comprising: a housing; a partition plate disposed within the housing, dividing the housing into a first cavity and a second cavity; a through groove on the partition plate connecting the first cavity and the second cavity; a limiting plate disposed at the through groove; a rotary drive assembly including a cylinder and rotating wheels at both ends, the rotating wheels being rotatably disposed within the first cavity and close to the through groove; a plurality of elastic filter assemblies circumferentially arranged between two rotating wheels; each elastic filter assembly including a roller and an elastic element, the elastic element elastically connecting the roller and the rotating wheel; a first adjustable gap being formed circumferentially between two adjacent rollers; a second adjustable gap being formed radially between the roller and the cylinder; and a third adjustable gap being formed radially between the limiting plate and the roller. The wastewater treatment device provided in this embodiment divides the tank into a first chamber and a second chamber by a partition plate, thereby providing space for liquid and solid components. By setting a limiting plate at the through groove, and driving the elastic filter component to rotate by a rotary drive component, and elastically connecting the roller and the wheel by an elastic element, the first, second, and third adjustable gaps can be dynamically adjusted during operation. This not only enhances the filtration effect and increases the water flow rate, but also allows silt to be automatically cleared during operation, and separates particulate matter or larger objects into the second chamber, avoiding silt accumulation and blockage by particulate matter or larger objects.

[0054] To make the above-mentioned objectives, features, and advantages of the embodiments of this application more apparent and understandable, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0055] Please refer to the attached document. Figure 1 -Appendix Figure 7 This application provides a wastewater treatment device, comprising:

[0056] Box 10;

[0057] A partition plate 20 is disposed inside the housing 10, dividing the housing 10 into a first cavity 101 and a second cavity 102; a through groove 201 is provided on the partition plate 20 to connect the first cavity 101 and the second cavity 102.

[0058] Limiting plate 50 is located at through groove 201;

[0059] The rotary drive assembly 30 is rotatably disposed within the first cavity 101 and close to the through groove 201; the rotary drive assembly 30 includes a cylinder 31 and rotating wheels 32 at both ends;

[0060] Multiple elastic filter components 40 are arranged circumferentially around the cylinder 31. Each elastic filter component 40 includes a roller 41 and an elastic element 42, with the elastic element 42 elastically connecting the roller 41 and the roller 32. A first adjustable gap 401 is formed circumferentially between two adjacent rollers 41. A second adjustable gap 402 is formed radially between the roller 41 and the cylinder 31. A third adjustable gap 403 is formed radially between the limiting plate 50 and the roller 41.

[0061] It should be noted that, in the description of the embodiments of this application, "first direction X" refers to the height direction of the box 10, and the first direction X is parallel to the direction of gravity; "second direction Y" refers to the length direction of the box 10; "third direction Z" refers to the width direction of the box 10; the first direction X, the second direction Y, and the third direction Z intersect each other. In the description of the embodiments of this application, "circumferential" refers to the circumferential direction of the cylinder 31 and / or the rotating wheel 32; "radial" refers to the radial direction of the cylinder 31 and / or the rotating wheel 32; and "axial" refers to the axial direction of the cylinder 31 and / or the rotating wheel 32.

[0062] Please see Figure 2As shown, the partition plate 20 is fixedly installed inside the box 10. The partition plate 20 divides the inside of the box 10 into an "L"-shaped first cavity 101 and a rectangular second cavity 102. The first cavity 101 is used to contain liquid components, and the second cavity 102 is used to contain solid components. The partition plate 20 is provided with a through groove 201 for waste materials to pass through. The through groove 201 has an extension width along the third direction Z. The through groove 201 connects the first cavity 101 and the second cavity 102.

[0063] Please combine them together Figure 2 and Figure 3 As shown, the limiting plate 50 is located at the through groove 201. The limiting plate 50 can be fixedly connected to the partition plate 20. The shape of the limiting plate 50 matches the circumferential motion trajectory of the roller 41.

[0064] Please combine them together Figure 2 and Figure 4 As shown, the rotary drive assembly 30 includes a cylinder 31 and two rotating wheels 32 at its two ends, with the rotating wheels 32 fixedly connected to the cylinder 31; multiple elastic filter components 40 are connected between the two rotating wheels 32, and the multiple elastic filter components 40 are arranged circumferentially around the cylinder 31, and the elastic filter components 40 move under the drive of the rotary drive assembly 30; the elastic filter component 40 includes a roller 41 and an elastic element 42, and the roller 41 is elastically connected to the rotating wheel 32 through the elastic element 42, so that the roller 41 can reciprocate radially relative to the cylinder 31 and / or the rotating wheel 32 under the combined action of centrifugal force, gravity, elastic force of the elastic element 42, water flow impact force and / or pressure of the accumulated material, thereby realizing the dynamic adjustment of the first adjustable gap 401, the second adjustable gap 402 and / or the third adjustable gap 403.

[0065] During operation, the rotary drive assembly 30 rotates, driving the elastic filter assembly 40 to move. Water flows from above the rotary drive assembly 30 along the first direction X, impacting the roller 41 above the cylinder 31 and flowing into the first cavity 101 through the first adjustable gap 401 and the second adjustable gap 402. Under normal operating conditions, the water flow exerts pressure on the roller 41 above the cylinder 31, causing the first adjustable gap 401 and the second adjustable gap 402 to decrease, thereby enhancing the filtration effect. Meanwhile, the roller 41 below the cylinder 31 is not subjected to water flow pressure, and due to centrifugal force, gravity, and / or the elastic force of the elastic element 42, the first adjustable gap 401 and the second adjustable gap 402 increase, resulting in a faster water flow rate.

[0066] When the roller 41 and the cylinder 31 become clogged due to the accumulation of mud and sand, when the roller 41 moves above the cylinder 31, it moves towards the center of the cylinder 31 due to the pressure of the water flow. The first adjustable gap 401 and the second adjustable gap 402 decrease, so that the mud and sand are squeezed out from between the roller 41 and the cylinder 31 through the first adjustable gap 401 and then removed by the limiting plate 50. Thus, after repeated pressing, the mud and sand are cleaned up, avoiding the accumulation and blockage of mud and sand.

[0067] If the blockage is particulate matter or a large object, it will fall between two adjacent rollers 41 and be caught by the peripheral wall of the roller 41. The blockage presses down on the roller 41, reducing the first adjustable gap 401 and decreasing the likelihood of the blockage passing through the first adjustable gap 401. When the blockage moves with the roller 41 to the position where it connects with the channel 201, the downward pressure on the roller 41 from the water flow decreases or the roller 41 is no longer under the pressure of the water flow, and the pressure on the roller 41 from the blockage gradually decreases. Under the action of centrifugal force and the elastic force of the elastic element 42, the roller 41 moves closer to the channel 201. At this time, the first adjustable gap 401 increases and the third adjustable gap 403 decreases. Under the action of centrifugal force, the blockage enters the second cavity 102 from the channel 201, thereby separating the blockage from the wastewater and preventing blockage by particulate matter or large objects.

[0068] The wastewater treatment device provided in this embodiment divides the tank 10 into a first chamber 101 and a second chamber 102 by a partition plate 20, thereby providing space for liquid and solid components. By setting a limiting plate 50 at the through groove 201, and driving the elastic filter assembly 40 to rotate by the rotation drive assembly 30, and elastically connecting the roller 41 and the rotating wheel 32 by the elastic element 42, the first adjustable gap 401, the second adjustable gap 402 and the third adjustable gap 403 can be dynamically adjusted during operation. This not only enhances the filtration effect and increases the water flow rate, but also allows the silt to be automatically cleaned during operation and separates particulate matter or larger objects into the second chamber 102, avoiding silt accumulation and blockage by particulate matter or larger objects.

[0069] In one possible implementation, the roller body 41 includes a first surface 411 disposed on both circumferential sides, and the first surfaces 411 of two adjacent roller bodies 41 are spaced apart to form a first adjustable gap 401.

[0070] The first adjustable gap 401 gradually decreases radially toward the center of the rotating wheel 32;

[0071] The gap width of the first adjustable gap 401 changes as the roller 41 moves radially.

[0072] In this embodiment, please refer to the following: Figure 5 and Figure 6 As shown, the roller 41 has a fan-shaped cross-section. The first surfaces 411 on both sides of the roller 41 are set at an angle, and the distance between the first surfaces 411 of two adjacent rollers 41 gradually decreases, that is, the first adjustable gap 401 gradually decreases. Thus, when the blockage falls between two adjacent rollers 41, the blockage is received by the first surfaces 411. At the same time, the blockage presses down on the roller 41, causing the first adjustable gap 401 to decrease, thereby preventing the blockage from entering the second adjustable gap 402. When the blockage moves with the roller 41 to the position where it connects with the through groove 201, the roller 41 moves towards the position closer to the through groove 201 under the action of centrifugal force and the elastic force of the elastic element 42. At this time, the first adjustable gap 401 increases, and the first adjustable gap 401 gradually increases in the radial direction away from the center of the wheel 32, which is conducive to the blockage entering the second cavity 102 from the through groove 201 under the action of centrifugal force.

[0073] In one possible implementation, please combine... Figure 5 and Figure 6 As shown, the roller body 41 also includes a first arc surface 412 and a second arc surface 413 disposed on both radial sides. The first arc surface 412 is located on the side of the roller body 41 that is radially away from the cylinder 31, and the area of ​​the first arc surface 412 is larger than the area of ​​the second arc surface 413. The second arc surface 413 and the outer peripheral surface of the cylinder 31 are radially spaced to form a second adjustable gap 402. The first adjustable gap 401 and the second adjustable gap 402 are connected.

[0074] The limiting plate 50 has a third arc surface 51 on the side facing the roller body 41. The third arc surface 51 and the first arc surface 412 are radially spaced to form a third adjustable gap 403. The third adjustable gap 403 is connected to the first adjustable gap 401 and the through groove 201.

[0075] The gap widths of the second adjustable gap 402 and the third adjustable gap 403 change as the roller 41 moves radially.

[0076] In this embodiment, water flows from above the rotary drive assembly 30 along the first direction X. Whenever the roller 41 moves above the cylinder 31, the water flows and impacts the first arc surface 412 of the roller 41, creating pressure on the roller 41. This reduces the first adjustable gap 401 and the second adjustable gap 402, thereby enhancing the filtration effect. When the roller 41 moves to the point where its first arc surface 412 is no longer impacted by the water flow, the roller 41 moves radially away from the cylinder 31 under the action of centrifugal force, gravity, and / or the elastic force of the elastic element 42. The first adjustable gap 401 and the second adjustable gap 402 increase, resulting in a faster water flow rate.

[0077] In one possible implementation, please combine... Figure 3 and Figure 4 As shown, the limiting plate 50 also includes a second surface 52 and a third surface 53 set at an angle. The second surface 52 is set at an angle to the circumferential end of the third arc surface 51 and forms a scraping part 54; the third surface 53 is connected to the partition plate 20.

[0078] In this embodiment, the shovel part 54 is disposed in the tangential direction of the circumferential motion trajectory of the roller 41. When the roller 41 and the cylinder 31 are blocked due to the accumulation of mud and sand, the roller 41 moves towards the center of the cylinder 31 under the action of water pressure. The first adjustable gap 401 and the second adjustable gap 402 are reduced, so that the mud and sand are squeezed out from between the roller 41 and the cylinder 31 through the first adjustable gap 401 and then removed by the shovel part 54. Thus, after repeated pressing, the mud and sand are cleaned up, avoiding the accumulation and blockage of mud and sand.

[0079] In one possible implementation, please combine... Figure 5 and Figure 6 As shown, limiting grooves 4101 are provided at both ends of the roller body 41 along the axial direction, and the limiting grooves 4101 extend radially.

[0080] The elastic filter assembly 40 also includes a limiting member 43, which is radially movably disposed in the limiting groove 4101 and is connected to the rotating wheel 32;

[0081] The elastic element 42 is disposed in the limiting groove 4101. One radial end of the elastic element 42 abuts against the limiting element 43, and the other end abuts against the inner wall of the limiting groove 4101.

[0082] In this embodiment, the rotating wheel 32 is fixedly connected to the cylinder 31, and the axial ends of the roller 41 are limited by the rotating wheel 32. The roller 41 can slide radially connected to the rotating wheel 32. The axial ends of the roller 41 are provided with radially extending limiting grooves 4101. One axial end of the limiting member 43 is fixedly connected to the rotating wheel 32, and the other end is movably disposed radially in the limiting groove 4101. Thus, through the cooperation between the limiting member 43 and the limiting groove 4101, the roller 41 can only move radially back and forth. By installing the elastic member 42 in the limiting groove 4101, one radial end of the elastic member 42 abuts against the limiting member 43, and the other end abuts against the inner wall of the limiting groove 4101. Thus, through the elastic member 42 abutting against the roller 41, the roller 41 always maintains the tendency to return to its original position, thereby realizing the dynamic adjustment of the first adjustable gap 401, the second adjustable gap 402 and the third adjustable gap 403 during the working process.

[0083] Furthermore, the elastic element 42 can be a spring.

[0084] In one possible implementation, please see Figure 1As shown, the housing 10 is provided with an input terminal 11 and an output terminal 12 that are connected to the first cavity 101. The input terminal 11 is located on the first direction X side of the housing 10, and the output terminal 12 is located on the second direction Y side of the housing 10.

[0085] Please see Figure 2 As shown, the partition plate 20 includes a first plate 21 and a second plate 22 arranged at an angle. The first plate 21 extends along a first direction X, and the second plate 22 extends along a second direction Y.

[0086] A through groove 201 is formed at the end of the first plate 21 near the input end 11 along the first direction X.

[0087] In this embodiment, by providing a partition plate 20 inside the housing 10, wherein a first plate 21 extends along a first direction X and a second plate 22 extends along a second direction Y, the interior of the housing 10 is divided into an "L"-shaped first cavity 101 and a rectangular second cavity 102. Please refer to [link to relevant documentation]. Figure 2 As shown, the first cavity 101 has a first section extending along the first direction X and a second section extending along the second direction Y. The input end 11 is located on the upper part of the housing 10. The rotary drive assembly 30, the elastic filter assembly 40, the limiting plate 50 and the through groove 201 are located in the first section along the first direction X near the input end 11, so that gravity and water pressure can be better utilized in combination with centrifugal force and the elastic force of the elastic element 42 to achieve dynamic adjustment of the roller body 41.

[0088] In one possible implementation, the discharge direction of the through-slot 201 is set at an angle to the feed direction of the input end 11.

[0089] In this embodiment, the discharge direction of the through trough 201 can be set along the second direction Y, and the feeding direction of the input end 11 can be set along the first direction X, so as to better utilize the combination of gravity and water pressure with centrifugal force and elastic force of elastic element 42 to achieve dynamic adjustment of roller body 41.

[0090] In one possible implementation, please see Figure 1 and Figure 2 As shown, the input terminal 11 and / or the output terminal 12 are provided with flanges 13.

[0091] By providing flanges 13 at the input end 11 and / or the output end 12, it is easy to connect the enclosure to external pipelines.

[0092] In one possible implementation, please see Figure 4 As shown, the rotating wheel 32 is provided with a rotating shaft 33 on the side away from the cylinder 31 along the axial direction. The rotating shaft 33 is coaxially arranged with the cylinder 31 and is rotatably connected to the side wall of the box 10.

[0093] The rotary drive assembly 30 also includes a motor 34, which is fixedly mounted on the side wall of the housing 10 and is connected to the rotating shaft 33 for transmission.

[0094] The motor 34 is connected to the rotating shaft 33, thereby driving the rotary drive component 30 to rotate. In turn, the rotary drive component 30 drives the elastic filter component 40 to move. During operation, the mud and sand are automatically cleaned, and particles or larger objects are separated into the second chamber 102, thus avoiding the accumulation and blockage of mud and sand and particles or larger objects.

[0095] In one possible implementation, please see Figure 2 As shown, the housing 10 is also provided with a cleaning port 103 that communicates with the second chamber 102. The cleaning port 103 is located on the side of the housing 10 away from the elastic filter assembly 40 along the second direction Y.

[0096] Please see Figure 1 As shown, the box body 10 is also provided with a cover 60, which is placed over the cleaning port 103.
