Description

Technical Field

[0001] The invention relates to the technical field of liquid impurity separation, and in particular to a liquid impurity separation device. Background Art

[0002] The wastewater generated during daily cleaning in the farm contains residues such as hair and feed residues, or the wastewater generated by flushing blood, visceral residues and grease during the slaughter process. These wastewaters need to be separated from the solid impurities during treatment so that they can be centrally treated later.

[0003] The patent document with the announcement number CN221155636U discloses a filtering device, including a filter screen, a frame, a rotating device, a rotating device, a collecting tank, and a flushing device, wherein the filter screen is fixed on the filter cartridge, one end of the filter cartridge is closed, and the other end is provided with an opening; the filter cartridge is mounted on the frame through a rotating device; the rotating device is respectively connected to the frame and the filter cartridge, and is used to drive the filter cartridge to rotate; the collecting tank is located in the filter cartridge and is connected to the frame, and a sewage pipe is provided at one end of the collecting tank; the flushing device is mounted on the frame, and is arranged opposite to the collecting tank, and is also located outside the filter cartridge, and the flushing device includes a water inlet pipe and a nozzle, the water inlet pipe is fixed on the frame, and is located between the water baffle and the filter cartridge, and the water inlet pipe is connected to a pump; the water inlet pipe is arranged parallel to the axis of the filter cartridge, the nozzle is fixed on the water inlet pipe, and a plurality of nozzles are arranged along the axial array of the water inlet pipe, and the nozzle is arranged opposite to the collecting tank. The flushing device is used to flush the filtered material on the filter screen into the collecting tank.

[0004] When the microfilter is working, it conveys wastewater into the rotating filter cartridge, where water flows out of the filter cartridge and impurities are trapped in the filter cartridge. Afterwards, these impurities move to the top of the rotating filter cartridge, and then the top filter cartridge is flushed by the flushing device set on the top of the filter cartridge, so that the impurities fall into the collection tank inside the filter cartridge that moves relative to the filter cartridge, and then are discharged. In addition, a screen that rotates with the filter cartridge is generally set inside the filter cartridge, and the screen rotates with the filter cartridge to drive the impurities to move to the top of the filter cartridge.

[0005] However, this solution still has the following problems: during filtration, the filter cartridge will be continuously backflushed to ensure its filtering capacity and discharge impurities at the same time. However, because the screen is set inside the filter cartridge and the flushing device is set outside the filter cartridge, the water sprayed by the flushing device will not flush the screen until it passes through the filter cartridge, and the filter cartridge continues to rotate during the process. The flushing device acts on the screen for a short time, which may lead to inadequate flushing of the screen. Over time, impurities on the screen will gradually accumulate. In addition, when treating aquaculture wastewater, the hair of animals in the wastewater is more likely to get stuck in the screen, causing the screen to gradually lose its filtering effect, affecting the transport of impurities. Summary of the invention

[0006] The present invention provides a liquid impurity separation device, aiming to solve the problem that the screen in the filter cylinder is prone to blockage due to insufficient flushing in the related art.

[0007] The liquid impurity separation device of the present invention includes a filter cylinder rotatably assembled on a frame. A flushing component, a collection component, and a control component are arranged on the frame. The flushing component is arranged above the filter cylinder, the collection component is arranged inside the filter cylinder, and the control component is arranged near the upper part of the filter cylinder. A plurality of auxiliary rods are circumferentially arranged on the inner wall of the filter cylinder. A screen is arranged on the auxiliary rods. An intermediate block is sleeved outside the auxiliary rods. The intermediate block is slidably assembled on the inner wall of the filter cylinder around the axis of the filter cylinder. The side surface of the auxiliary rod is in sliding contact with the inner wall of the filter cylinder. A first elastic member connected to the intermediate block is arranged on the inner wall of the filter cylinder. A plurality of top blocks corresponding to the plurality of auxiliary rods are arranged at the end of the filter cylinder. When the auxiliary rod moves to the flushing component, the intermediate block cooperates with the control component, and the intermediate block slides relative to the filter cylinder, so that the auxiliary rod is stationary relative to the flushing component, and at the same time, the first elastic member is compressed. When the top block cooperates with the control component, the control component releases the restriction on the intermediate block, and the first elastic member releases to drive the auxiliary rod to move to the initial position.

[0008] The effect is that the wastewater to be treated is introduced into the filter cylinder. After the wastewater is filtered by the filter cylinder, it is discharged. The filter cylinder rotates, and at the same time drives the screen to rotate synchronously. The screen drives the impurities located at the bottom of the filter cylinder to move to the top of the filter cylinder, that is, above the collection component, and transfers the impurities into the collection component. At the same time, the control component cooperates with the intermediate block, and the intermediate block, the auxiliary rod, and the screen all stop moving. At this time, the screen is stationary relative to the flushing component. Until the top block moves to the control component, the control component releases the restriction on the intermediate block, and the intermediate block moves to the initial position under the action of the first elastic member. By setting the cooperation between the control component and the intermediate block, when the filter cylinder is continuously rotating, the residence time of the screen at the flushing component is increased, thereby improving the flushing effect of the flushing component on the screen and reducing the phenomenon of screen blockage.

[0009] Preferably, a mounting plate is coaxially arranged inside the filter cylinder. The mounting plate is fixedly connected to the frame. The control component includes a clamping rod and a second elastic member. The clamping rod is slidably arranged on the mounting plate towards the filter cylinder. The second elastic member is respectively connected to the clamping rod and the mounting plate. The second elastic member is used to drive the end of the clamping rod to move into the filter cylinder. When the auxiliary rod rotates to the flushing component, the intermediate block abuts against the clamping rod to fix the intermediate block.

[0010] The effect is that the clamping rod is located at the top of the filter cylinder, that is, the clamping rod corresponds to the flushing component. After the intermediate block moves above the collection component, the intermediate block cooperates with the clamping block, so that the intermediate block stops moving and is restricted.

[0011] Preferably, the clamping rod includes a pushing portion, the filter cartridge includes a connecting portion provided at its end, the connecting portion is provided on the side of the mounting plate close to the inside of the filter cartridge, the top block is provided on the connecting portion, the pushing portion is provided on the side of the connecting portion close to the mounting plate, the top block is provided with a guiding inclined surface, when the top block moves to the pushing portion, the guiding inclined surface abuts against the pushing portion, and different positions on the guiding inclined surface abutting against the pushing portion drive the clamping rod to separate from the intermediate block.

[0012] The effect is that after the clamping rod abuts against the intermediate block, the filter cartridge continues to rotate, the filter cartridge drives the top block to rotate through the connecting portion, after the top block rotates to the pushing portion, the guiding inclined surface abuts against the pushing portion, and as the filter cartridge continues to rotate, different positions on the guiding inclined surface are driven to abut against the pushing portion, driving the pushing portion away from the intermediate block, and further driving the clamping rod away from the intermediate block until the clamping rod separates from the intermediate block, releasing the restriction on the intermediate block. In addition, a plurality of top blocks are correspondingly arranged for a plurality of intermediate blocks, and the position of the clamping rod is adjusted through the top block, so that before the next intermediate block moves to the clamping rod, the clamping rod separates from the intermediate block, so that the next intermediate block can move to cooperate with the clamping rod again, and then the above operation is repeated to clean the barrier net.

[0013] Preferably, an arc-shaped first rack is provided on the connecting portion, the auxiliary rod is rotationally matched with the intermediate block, and a first gear meshing with the first rack is coaxially provided at the end of the auxiliary rod. When the intermediate block moves relative to the filter cartridge, the first gear cooperates with the first rack to drive the auxiliary rod to rotate self.

[0014] The effect is that the first gear and the first rack always remain in a meshing state, and both rotate synchronously with the filter cartridge. After the clamping rod abuts against the intermediate block, the auxiliary rod and the intermediate block stop moving, the first gear moves relative to the first rack, and at the same time the first gear rotates, thereby driving the auxiliary rod to rotate self, and finally realizing that the auxiliary rod rotates self when moving relative to the filter cartridge, so as to scrape the impurities on the inner wall of the filter cartridge and improve the cleaning effect of the filter cartridge.

[0015] Preferably, a connecting sleeve is provided on the barrier net, the connecting sleeve is rotatably sleeved outside the auxiliary rod, and an arc-shaped surface is provided on the side of the connecting sleeve close to the filter cartridge, and the arc-shaped surface is in sliding abutment with the inner wall of the filter cartridge.

[0016] The effect is that the barrier net is rotationally matched with the auxiliary rod through the connecting sleeve, and an arc-shaped surface is provided on the side of the connecting sleeve, and the arc-shaped surface is in sliding abutment with the inner wall of the filter cartridge, that is, the connecting sleeve can only slide relative to the filter cartridge, reducing the phenomenon that the connecting sleeve rotates with the auxiliary rod. That is, when the auxiliary rod rotates, the barrier net remains stationary relative to the filter cartridge through the connecting sleeve, reducing the phenomenon of mutual interference between the barrier net and the auxiliary rod.

[0017] Preferably, the auxiliary rod is of a hollow structure, and an opening is provided at one end of the auxiliary rod facing away from the first gear. A plurality of spray nozzles are circumferentially arranged on the side surface of the auxiliary rod. A docking frame is arranged on the frame. The docking frame is of a hollow structure. A water outlet is arranged on one side of the docking frame close to the filter cylinder. A second water pipe communicating with the flushing assembly is arranged on the docking frame. When the middle block abuts against the clamping rod, the opening of the auxiliary rod communicates with the water outlet, so that water is sprayed onto the inner walls of the barrier net and the filter cylinder through the spray nozzles.

[0018] The effect is that after the middle block rotates to abut against the clamping block, the auxiliary rod moves to the docking frame. At this time, the water outlet of the docking frame communicates with the opening of the auxiliary rod. While the water in the flushing assembly flushes the outside of the filter cylinder, it enters the docking frame through the second water pipe and finally sprays out through the spray nozzles on the auxiliary rod to assist in cleaning the inner walls of the barrier net and the filter cylinder.

[0019] Preferably, the flushing assembly includes a first water pipe and a spray head. A plurality of spray heads are arranged along the axial direction of the filter cylinder. The spray heads are arranged above the filter cylinder and correspond to the outside of the filter cylinder.

[0020] The effect is that the first water pipe sprays water through the spray heads. At the same time, the sprayed water is sprayed on the outside of the filter cylinder and then enters the filter cylinder through the filter cylinder to flush the barrier net inside the filter cylinder.

[0021] Preferably, the collection assembly includes a collection frame and a waste discharge pipe. The collection frame is connected to the frame. The collection frame is arranged along the direction parallel to the axis of the filter cylinder. The collection frame is arranged above the axis of the filter cylinder. The waste discharge pipe is communicated with the collection frame. One end of the waste discharge pipe facing away from the collection frame extends to the outside of the filter cylinder.

[0022] The effect is that when the barrier net rotates to the upper part of the filter cylinder, it moves to the upper part of the collection frame. At this time, the lower end of the barrier net is arranged downward. The impurities on the barrier net slide into the collection frame under the action of their own gravity. At the same time, the impurities on the barrier net and the top of the filter cylinder will also fall into the collection frame under the action of the flushing assembly. Then the impurities in the collection frame are discharged through the waste discharge pipe for centralized cleaning of the impurities.

[0023] Preferably, a driving member is arranged on the frame. A second gear is arranged at the output end of the driving member. A second rack is coaxially arranged outside the filter cylinder. The second gear meshes with the second rack.

[0024] The effect is that the driving member drives the second gear to rotate. The rotation of the second gear drives the second rack to rotate. The rotation of the second rack drives the filter cylinder to rotate, thereby adjusting the position of the barrier net for collecting and processing impurities.

[0025] Preferably, one end of the barrier net close to the axis of the filter cylinder is inclined along the rotation direction of the filter cylinder.

[0026] The effect is that when the blocking net rotates with the filter cartridge and is located at the bottom of the filter cartridge, the blocking net is in an inclined state. The inclined blocking net is used to collect impurities at the bottom of the filter cartridge and drive the impurities to move to the top of the filter cartridge, so as to transfer the impurities into the collection box.

[0027] Beneficial effects: 1. In the present invention, the middle block is slidably assembled on the inner wall of the filter cartridge. After the middle block moves to the top of the filter cartridge, the clamping rod cooperates with the middle block until the top block contacts the clamping rod, so that when the filter cartridge continues to rotate, the middle block can stay at the top of the filter cartridge for a period of time, increasing the residence time of the blocking net at the flushing assembly to improve the cleaning effect on the blocking net.

[0028] 2. A connecting part that rotates synchronously with the filter cartridge is arranged on the filter cartridge. A first rack is arranged on the connecting part. The auxiliary rod is rotationally matched with the middle block. A first gear that meshes with the first rack is arranged on the auxiliary rod. When the middle block cooperates with the clamping strip, the first rack and the first gear drive the auxiliary rod to rotate, and at the same time the auxiliary rod moves relative to the filter cartridge to scrape off the impurities adhered to the inner wall of the filter cartridge, assisting the flushing assembly to clean the filter cartridge and improving the cleaning effect on the filter cartridge.

[0029] 3. A plurality of spray nozzles are opened on the auxiliary rod. After the auxiliary rod moves to the top of the filter cartridge, the inside of the auxiliary rod is communicated with the docking frame, so that the water in the flushing assembly is sprayed onto the filter cartridge and the blocking net through the spray nozzles, assisting in cleaning the blocking net and the filter cartridge and improving the cleaning effect on the blocking net.

[0030] 4. A first elastic member connected to the inner wall of the filter cartridge is arranged on the middle block. When the filter cartridge rotates, the first elastic member drives the middle block to rotate with the filter cartridge, and then drives the blocking net to rotate with the filter cartridge to drive the impurities to move to the top of the filter cartridge. After the middle block cooperates with the clamping rod, the middle block stops moving. At this time, the filter cartridge continues to rotate, and the first elastic member is compressed. After the top block cooperates with the clamping rod and drives the clamping rod to separate from the middle block, the compressed first elastic member is released, driving the middle block to slide on the inner wall of the filter cartridge until the middle block moves relative to the filter cartridge to the initial position. At the same time, the clamping rod is reset under the action of the second elastic member to intercept the next middle block and clean multiple blocking nets one by one, improving the overall cleaning effect.

[0031] 5. A connecting sleeve connected to the auxiliary rod is arranged on the blocking net. The connecting sleeve is rotationally matched with the auxiliary rod, and the side surface of the connecting sleeve is slidably matched with the side surface of the filter cartridge. When the auxiliary rod rotates, the connecting sleeve rotates relative to the auxiliary rod, and at the same time the side surface of the connecting sleeve remains in contact with the inner wall of the filter cartridge to support the blocking net, so that the blocking net remains in an inclined state and reduces the phenomenon of mutual interference between the blocking net and the auxiliary rod.

Detailed implementation manners

[0042] The following details the embodiments of the present invention, and the examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation to the present invention.

[0043] As Figures 1 to 9As shown in the figure, the liquid impurity separation device of the present invention includes a frame 1, a filter cylinder 2, a flushing assembly 3, and a collection assembly 4. The filter cylinder 2 is horizontally and rotatably assembled on the frame 1. An auxiliary rod 5 and a retaining net 6 are arranged inside the filter cylinder 2. Multiple groups of the auxiliary rod 5 and the retaining net 6 are respectively arranged around the axis of the filter cylinder 2. The retaining net 6 is connected to the filter cylinder 2 through the auxiliary rod 5. The flushing assembly 3 is arranged above the filter cylinder 2, and the collection assembly 4 is arranged inside the filter cylinder 2. The control assembly 8 is arranged near the top of the filter cylinder 2.

[0044] The wastewater to be treated is introduced into the filter cylinder 2 and filtered through the filter cylinder 2. The wastewater flows out, and the solid impurities in the wastewater are intercepted in the filter cylinder 2. As the filter cylinder 2 rotates, the retaining net 6 is driven to rotate accordingly. The retaining net 6 drives the impurities in the filter cylinder 2 to rotate with the filter cylinder 2. When the impurities rotate above the collection assembly 4, they are separated from the retaining net 6, causing the impurities to fall into the collection assembly 4. At the same time, the flushing assembly 3 flushes the top of the filter cylinder 2 to clean the filter cylinder 2.

[0045] Refer to Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 As shown in the figure, an intermediate block 7 is arranged outside the auxiliary rod 5. The intermediate block 7 is sleeved outside the auxiliary rod 5 and is slidably assembled on the inner wall of the filter cylinder 2. The intermediate block 7 slides around the axis of the filter cylinder 2 on the inner wall of the filter cylinder 2. The auxiliary rod 5 is connected to the filter cylinder 2 through the intermediate block 7. A first elastic member 71 is arranged on the inner wall of the filter cylinder 2. The first elastic member 71 is set as a spring, and the spring is connected to the intermediate block 7. A control assembly 8 is arranged on the frame 1. The control assembly 8 is arranged inside the filter cylinder 2 and near the upper part of the filter cylinder 2. A plurality of top blocks 9 are arranged at the end of the filter cylinder 2. The plurality of top blocks 9 and the plurality of auxiliary rods 5 are arranged in one-to-one correspondence.

[0046] When the filter cylinder 2 rotates, it drives the intermediate block 7, the auxiliary rod 5, and the retaining net 6 to rotate synchronously. After the auxiliary rod 5 rotates to the top of the filter cylinder 2, the auxiliary rod 5 corresponds to the flushing assembly 3. The control assembly 8 cooperates with the intermediate block 7 to restrict the intermediate block 7, so that the intermediate block 7 stops rotating with the filter cylinder 2. At this time, the intermediate block 7, the auxiliary rod 5, and the retaining net 6 are relatively stationary with respect to the flushing assembly 3. The filter cylinder 2 continues to rotate, and the first elastic member 71 is compressed until the top block 9 rotates to the control assembly 8 and cooperates with the control assembly 8 to release the restriction of the control assembly 8 on the intermediate block 7. The first elastic member 71 drives the intermediate block 7 and the auxiliary rod 5 to move to the initial position.

[0047] By the cooperation of the control assembly 8 and the intermediate block 7, the auxiliary rod 5 and the retaining net 6 stay at the top of the filter cylinder 2 for a period of time, that is, the staying time of the retaining net 6 at the flushing assembly 3 is increased, the flushing duration of the flushing assembly 3 on the retaining net 6 is increased, and the flushing effect on the retaining net 6 is improved.

[0048] In addition, there are multiple top blocks 9 corresponding to multiple auxiliary rods 5, so that before the next intermediate block 7 moves to the latch rod 81, the latch rod 81 is separated from the intermediate block 7, so that the next intermediate block 7 can move to cooperate with the latch rod 81 again, and then the above operation is repeated to clean the netting 6.

[0049] The side surface of the auxiliary rod 5 is in sliding contact with the inner wall of the filter cylinder 2. When the intermediate block 7 is stationary relative to the flushing assembly 3, the auxiliary rod 5 moves relative to the inner wall of the filter cylinder 2, and the impurities adhered to the inner wall of the filter cylinder 2 can be scraped off by the side surface of the auxiliary rod 5, improving the cleaning effect of the filter cylinder 2.

[0050] Refer to Figure 2 、 Figure 3 、 Figure 8 As shown in

[0051] Refer to Figure 5 、 Figure 6 、 Figure 7 The control assembly 8 includes: a latch rod 81 and a second elastic member 82. The latch rod 81 is slidably arranged on the mounting plate 11 towards the filter cylinder 2, that is, the sliding direction of the latch rod 81 is parallel to the axis of the filter cylinder 2. The second elastic member 82 is arranged as a spring, one end of the spring is connected to the latch rod 81, and the other end is connected to the mounting plate 11. The second elastic member 82 is used to drive the latch rod 81 to move towards the inside of the filter cylinder 2.

[0052] In the initial state, the end of the latch rod 81 close to the filter cylinder 2 is located in the rotation plane of the intermediate block 7. When the intermediate block 7 rotates to the lower part of the flushing assembly 3, the intermediate block 7 abuts against the latch block. At this time, the filter cylinder 2 continues to rotate, the intermediate block 7 rotates relative to the filter cylinder 2, and the intermediate block 7 is in a stationary state, restricting the intermediate block 7.

[0053] Refer to Figure 5 、 Figure 6 、 Figure 7 As shown in

[0054] When the clamping rod 81 abuts against the middle rod, the filter cartridge 2 continues to rotate, driving the top block 9 to move between the pushing part 811 and the connecting part 21. At the same time, the guiding inclined surface 91 abuts against the pushing part 811. Different positions on the guiding inclined surface 91 abut against the pushing part 811, driving the pushing part 811 away from the middle block 7 until the clamping rod 81 is separated from the middle block 7, releasing the restriction on the middle block 7, so that the middle block 7, the auxiliary rod 5 and the netting 6 move to the initial position under the action of the second elastic member 82.

[0055] Refer to Figure 5 、 Figure 6 、 Figure 7 As shown in FIGS.

[0056] A first rack 211 is arranged on the connecting part 21. The first rack 211 is arranged in an arc around the axis of the filter cartridge 2. The auxiliary rod 5 is rotationally matched with the middle rod. A first gear 51 is arranged at one end of the auxiliary rod 5 close to the first rack 211. The first gear 51 meshes with the first rack 211.

[0057] Refer to Figure 2 、 Figure 5 As shown in FIGS.

[0058] Refer to Figure 5 As shown in FIGS.

[0059] Refer to Figure 1 、 Figure 2The flushing assembly 3 includes: a water pipe 31 and a nozzle 32. The water pipe 31 and the nozzle 32 are both arranged above the filter cartridge 2. The water pipe 31 is arranged parallel to the axis of the filter cartridge 2. A plurality of nozzles 32 are arranged along the length direction of the water pipe 31, that is, the plurality of nozzles 32 are arranged along the axis direction parallel to the filter cartridge 2. The output end of the nozzle 32 is downward toward the filter cartridge 2, and the nozzle 32 is connected to the inside of the water pipe 31. Water is sprayed through the water pipe and the nozzle 32 to flush the filter cartridge 2 and the screen 6.

[0060] Reference Figure 1 , Figure 5 The auxiliary rod 5 is a hollow structure, and a plurality of nozzles 52 are circumferentially provided on the side of the auxiliary rod 5. A docking frame 14 is provided on the frame 1. The docking frame 14 is provided at one end of the auxiliary rod 5 away from the first gear 51. A water outlet 141 is provided on the side of the docking frame 14 close to the auxiliary rod 5. A water pipe 15 is provided on the docking frame 14. One end of the water pipe 15 is connected to the inside of the docking frame 14, and the other end is connected to the water pipe 1 31. An opening is provided at one end of the auxiliary rod 5 away from the first gear 51, that is, the opening is provided on the side of the auxiliary rod 5 close to the docking frame 14.

[0061] Reference Figure 5 When the clamping rod 81 abuts against the middle block 7, the auxiliary rod 5 rotates to the docking frame 14, the opening is connected to the water outlet 141, and the water in the water pipe 1 31 enters the docking frame 14 through the water pipe 2 15, and then enters the auxiliary rod 5 through the opening and the water outlet 141 in sequence, and finally sprays out through the nozzle 52 to wash the screen 6 and the inner wall of the filter cartridge 2. In addition, because the auxiliary rod 5 is close to the screen 6, impurities on the screen 6 can be cleaned, thereby improving the cleaning effect of the screen 6.

[0062] The water outlet 141 on the docking frame 14 is continuously in an open state, that is, when the auxiliary rod 5 has not moved to the docking frame 14 , the water outlet 141 is in a continuous water spraying state, which assists in flushing the inner wall of the filter cartridge 2 and improves the cleaning effect of the filter cartridge 2 .

[0063] Reference Figure 1 , Figure 2 , Figure 9 The collecting assembly 4 includes: a collecting frame 41 and a drainage pipe 42. The collecting frame 41 is connected to the frame 1. The collecting frame 41 is arranged in the filter cartridge 2, and the collecting frame 41 is arranged above the axis of the filter cartridge 2. The drainage pipe 42 is connected to the collecting frame 41, and one end of the drainage pipe 42 away from the collecting frame 41 extends to the outside of the filter cartridge 2.

[0064] When the blocking net 6 rotates above the collection box 41, the impurities on the blocking net 6 are separated from the blocking net 6 under the action of its own gravity and the ejected water and enter the collection box 41. Additionally, filter holes can be opened at the bottom of the collection box 41. After the impurities enter the filter box, the water contained in the impurities is filtered again, and finally discharged through the impurity discharge pipe 42 for centralized treatment of the impurities.

[0065] Referring to Figure 1 , Figure 2 , a driving member 16 is provided on the frame 1. The driving member 16 is set as a motor. A second gear 161 is provided at the output end of the driving member 16. The second gear 161 is coaxially connected to the output end of the driving member 16. A second rack 162 is provided outside the filter cylinder 2. The second rack 162 is arranged in a circular ring around the filter cylinder 2. The second rack 162 is coaxially connected to the filter cylinder 2. The second gear 161 meshes with the second rack 162. The driving member 16 drives the filter cylinder 2 to rotate through the second gear 161 and the second rack 162.

[0066] The implementation principle of the present invention is as follows: After the filter cylinder 2 filters the wastewater, it drives the blocking net 6 to rotate. After the blocking net 6 drives the impurities at the bottom of the filter cylinder 2 to move to the top of the filter cylinder 2, the clamping rod 81 abuts against the middle block 7. Before the top block 9 contacts the top pushing portion 811, both the auxiliary rod 5 and the blocking net 6 are relatively stationary with respect to the flushing assembly 3, so as to increase the residence time of the blocking net 6 at the flushing assembly 3, thereby improving the cleaning effect on the blocking net 6. After another blocking net 6 is about to move to the top of the filter cylinder 2, the top block 9 cooperates with the top pushing portion 811 on the clamping rod 81 to drive the clamping rod 81 to separate from the middle block 7, releasing the restriction on the middle rod. At the same time, after the top block 9 separates from the clamping rod 81, the elastic member two 82 drives the clamping rod 81 to move to the initial position, so as to cooperate with the next middle block 7, thereby controlling the residence time of the next blocking net 6 at the flushing assembly 3, and repeating the above operations to clean multiple blocking nets 6 in sequence.

[0067] At the same time, the auxiliary rod 5 slides relative to the filter cylinder 2, and the impurities on the inner wall of the filter cylinder 2 can be scraped off. Additionally, after the middle block 7 abuts against the clamping rod 81, the opening of the auxiliary rod 5 communicates with the water outlet 141 of the docking frame 14, and the water sprays out through the spray holes 52 on the side of the auxiliary rod 5 to flush the blocking net 6 again, improving the cleaning effect on the blocking net 6, reducing the phenomenon of blockage of the blocking net 6, and improving the separation efficiency of liquid impurities.

[0068] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
