[0028] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0029] As Figures 1 to 3 shown, a rural domestic sewage degradation treatment device described in an embodiment of the present invention includes a processing body 1; a filter rack 11 is fixedly connected to the inner wall of the end of the processing body 1, the cross-sectional shape of the filter rack 11 is Y-shaped, and a plurality of V-shaped grooves are formed in the filter rack 11; a servo motor 12 is fixedly connected to the outer wall of the processing body 1; an output end of the servo motor 12 is fixedly connected to a first rotating roller 13, and the first rotating roller 13 is rotatably connected to the inner wall of the processing body 1; a plurality of rake racks 14 are fixedly connected to the outer wall of the first rotating roller 13, and the shape of the rake racks 14 corresponds to the V-shaped grooves; a degradation component is arranged at the bottom end of the processing body 1, and the degradation component is used for multi-stage treatment of rural domestic sewage filtered by the filter rack 11; when degrading and treating rural domestic sewage, taking the processing body 1 as the main framework of the rural domestic sewage degradation treatment device, introducing the sewage onto the filter rack 11 for filtration, the Y-shaped filter rack 11 can filter a large number of solid impurities with strange shapes such as pesticide bottles and cans, plant roots and branches at the included angle, as the output end of the servo motor 12 drives the first rotating roller 13 to rotate, the plurality of rake racks 14 on the first rotating roller 13 respectively pass through the V-shaped grooves of the filter rack 11 to fish out the solid impurities in the sewage, as the output end of the servo motor 12 continuously rotates, the rake racks 14 turn the fished-out solid impurities to the blanking collection place, removing the solid impurities in the rural sewage, and the sewage after removal falls into the degradation component, adding a degradation agent to the sewage for multi-stage treatment and degradation operations, which can play a role in pre-treating rural domestic sewage and improving the degradation treatment effect of rural domestic sewage.

[0030] On both sides of the rake frame 14, a first side baffle 2 is fixedly connected; the cross-sectional shape of the rake frame 14 is F-shaped; at the included angle at one end of the rake frame 14 away from the first rotating roller 13, a cutting knife 21 is fixedly connected; when salvaging strange-shaped solid impurities in rural domestic sewage, the filter frame 11 is used to filter out the solid impurities, and the F-shaped rake frame 14 rotates with the first rotating roller 13 to salvage the solid impurities filtered on the filter frame 11. The solid impurities are temporarily stored between the two short rods of the F-shaped rake frame 14 and transported to the blanking place, playing a role in transporting the solid impurities. At the same time, some solid impurities are stuck in the V-shaped grooves of the filter frame 11. A plurality of cutting knives 21 are fixed at the included angle of the rake frame 14. As the rake frame 14 approaches and fits with the filter frame 11, the cutting knives 21 cut the stuck solid impurities, improving the collection effect of the solid impurities.

[0031] As Figure 1 and Figure 2 shown, on the inner wall of the processing body 1 away from the filter frame 11, a guide plate 3 is fixedly connected, and a long slot corresponding to the rake frame 14 is opened on the guide plate 3; on both sides of the guide plate 3, a second side baffle 31 is fixedly connected; when the rake frame 14 rotates with the first rotating roller 13 to salvage the solid impurities in the sewage on the filter frame 11, the solid impurities are transported to the blanking place as the rake frame 14 rotates. As the rake frame 14 rotates and tilts, the solid impurities fall from the rake frame 14 onto the guide plate 3. The two second side baffles 31 block the solid impurities falling on the guide plate 3, making the solid impurities be guided to fall and be collected and temporarily stored at the blanking place, playing a role in guiding and collecting the solid impurities. At the same time, the long slot on the guide plate 3 can scrape the solid impurities remaining on the rake frame 14, reducing some impurities adhering to the rake frame 14.

[0032] The degradation component includes a degradation tank 4, a first filter partition 41, and a second filter partition 42; the degradation tank 4 is fixedly connected to the bottom end of the treatment body 1; the first filter partition 41 is fixedly connected to the inner wall of the degradation tank 4, and three rows of overflow holes are opened on the first filter partition 41, and the first filter partition 41 is located at the middle position of the degradation tank 4; the second filter partition 42 is fixedly connected to the inner wall of the degradation tank 4, and one row of overflow holes is opened on the second filter partition 42, and the second filter partition 42 is located at the middle position between the inner wall of the degradation tank 4 and the first filter partition 41; when degrading the pretreated rural domestic sewage, the first filter partition 41 and the second filter partition 42 cooperate to divide the interior of the degradation tank 4 into three storage pools, namely a degradation pool, a recovery pool, and a garbage pool. The degradation pool is located at the bottom of the treatment body 1, and the pretreated rural domestic sewage falls from the filter rack 11 into the degradation pool, and a degradation agent is added to the degradation pool for precipitation and degradation. As the sewage continues to be injected, the water in the degradation pool flows into the recovery pool through the three rows of overflow holes on the first filter partition 41. The water in the recovery pool is relatively cleaner than that in the other two pools, and a water pump can be used to pump out the water inside for recovery treatment. The garbage pool is used to collect the solid impurities guided and dropped by the guide plate 3, and the one row of overflow holes opened on the second filter partition 42 is used to prevent the water level in the recovery pool from being too high, playing a role in the hierarchical degradation treatment of rural domestic sewage.

[0033] As Figure 1 , Figure 2 , Figure 4 and Figure 5 shown, a plurality of second rotating rollers 5 are rotatably connected to the inner wall of the degradation tank 4, and the second rotating rollers 5 are connected by a first belt to the first rotating roller 13, and two second rotating rollers 5 are connected by a second belt; a plurality of stirring plates 51 are fixedly connected to the outer wall of the second rotating roller 5; when the pretreated rural domestic sewage falls into the degradation tank 4 for degradation treatment, the output end of the servo motor 12 is used to drive the first rotating roller 13 to rotate, the first rotating roller 13 synchronously drives the second rotating rollers 5 connected by the first belt to rotate, and the plurality of stirring plates 51 stir the sewage inside the degradation tank 4 as the second rotating rollers 5 rotate, improving the mixing effect of the degradation agent and the sewage. At the same time, the second belt connects the two second rotating rollers 5, enabling multiple second rotating rollers 5 to rotate synchronously when one second rotating roller 5 rotates, improving the stirring effect on the sewage in the degradation tank 4.

[0034] A plurality of collecting grooves are formed in the stirring plates 51; on both sides of the collecting grooves on the plurality of stirring plates 51, a first filter screen plate 6 and a second filter screen plate 61 are fixedly connected respectively, and the length of the second filter screen plate 61 is shorter than that of the first filter screen plate 6; a flow guiding plate 62 is fixedly connected between the first filter screen plate 6 and the second filter screen plate 61 on the first filter screen plate 6; when the solid impurities in the sewage are pretreated, the fine impurities in the sewage then fall into the interior of the degradation tank 4. A collecting groove is formed in the stirring plate 51, and the first filter screen plate 6 and the second filter screen plate 61 are respectively fixed on both sides of the collecting groove. As the second rotating roller 5 drives the plurality of stirring plates 51 to rotate, the sewage is filtered through the first filter screen plate 6 and the second filter screen plate 61, and part of the sewage enters the space between the first filter screen plate 6 and the second filter screen plate 61 through the opening formed by the second filter screen plate 61 for further filtration. The flow guiding plate 62 guides the sewage, and under the influence of centrifugal force, some of the impurities filtered from the sewage are collected between the first filter screen plate 6 and the second filter screen plate 61, playing a role in cleaning the fine impurities in the sewage.

[0035] As Figure 1 , Figure 2 and Figure 6 shown, a storage tank 7 is fixedly connected to the outer wall of the processing body 1; a sealing plug 71 is inserted into the storage tank 7; a plurality of flow guiding pipes 72 are fixedly connected to the inner wall of the processing body 1 in an inclined manner, and the plurality of flow guiding pipes 72 are communicated with the bottom of the storage tank 7; a flow control mechanism is arranged at one end of the interior of the processing body 1 close to the flow guiding pipes 72, and the flow control mechanism is used to control the blocking of the degradation agent inside the flow guiding pipes 72; when degrading the pretreated rural domestic sewage, the sealing plug 71 is opened to add the degradation agent into the storage tank 7, and the degradation agent is fed down through the plurality of flow guiding pipes 72 to the flow control mechanism. As the flow control mechanism controls the feeding of the degradation agent, as the output end of the servo motor 12 drives the first rotating roller 13 to rotate, the first rotating roller 13 triggers the flow control mechanism to intermittently add the degradation agent into the interior of the degradation tank 4, playing a role in intermittently adding the degradation agent into the degradation tank 4.

[0036] The flow control mechanism includes a flow control plate 8, a plugging plate 81, a fixing frame 82 and a transmission component; the flow control plate 8 is fixedly connected inside the processing body 1, and the flow control plate 8 is located at the end of the diversion pipe 72 away from the storage tank 7; a plurality of the plugging plates 81 are slidably connected to the inner wall of the flow control plate 8; the fixing frame 82 is fixedly connected to the outer walls of the plurality of plugging plates 81; the transmission component is arranged on the fixing frame 82, and the transmission component is used to drive the fixing frame 82 to slide; when controlling the flow of the degradation agent at the plurality of diversion pipes 72, the first rotating roller 13 rotates along with the output end of the servo motor 12 to drive the transmission component to move, and the transmission component drives the fixing frame 82 to slide up and down. When the fixing frame 82 slides down, the plurality of plugging plates 81 slide down synchronously with the fixing frame 82. At this time, the feeding channel of the diversion pipe 72 is opened, and the degradation agent falls from the flow control plate 8 into the internal mixed sewage of the degradation tank 4. When the fixing frame 82 slides up, the plurality of plugging plates 81 slide up synchronously with the fixing frame 82. At this time, the feeding channel of the diversion pipe 72 is blocked by the upward sliding of the plugging plate 81, and the degradation agent is blocked in the diversion pipe 72, playing a role in controlling and blocking the feeding of the degradation agent.

[0037] The transmission component includes a fixing block 9, a sliding frame 91 and a convex block 92; the fixing block 9 is fixedly connected to the inner wall of the processing body 1; the sliding frame 91 is slidably connected to the inner wall of the fixing block 9 through an elastic member. The top end of the sliding frame 91 is arc-shaped, and the bottom end of the sliding frame 91 is fixedly connected to the fixing frame 82; the convex block 92 is fixedly connected to the outer wall of the first rotating roller 13, and the convex block 92 is arranged corresponding to the sliding frame 91; when controlling the up and down sliding of the fixing frame 82, the first rotating roller 13 rotates along with the output end of the servo motor 12, and the convex block 92 rotates synchronously with the first rotating roller 13. When the convex block 92 approaches the arc end of the sliding frame 91, the convex block 92 squeezes the arc end of the sliding frame 91, causing the sliding frame 91 to slide down inside the fixing block 9, and the elastic member inside the fixing block 9 is compressed and stressed when the sliding frame 91 is squeezed. The sliding frame 91 synchronously drives the fixing frame 82 to slide down to open the blockage at the diversion pipe 72. When the convex block 92 rotates away from the arc end of the sliding frame 91 along with the first rotating roller 13, the elastic member inside the fixing block 9 returns to its original position elastically, and the elastic member squeezes the sliding frame 91 to slide up. The sliding frame 91 synchronously drives the fixing frame 82 to slide up to block the diversion pipe 72, playing a role in driving the fixing frame 82 to slide up and down.

[0038] As Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the top end of the flow guiding plate 62 is arranged in a curved arc shape, and an arc groove is arranged on the side of the flow guiding plate 62 away from the second rotating roller 5; when degrading and treating the pretreated rural domestic sewage, the stirring plate 51 rotates along with the second rotating roller 5, and part of the sewage enters between the first filter plate 6 and the second filter plate 61 through the opening at the second filter plate 61. Guided by the curved arc surface at the top end of the flow guiding plate 62, the sewage enters the deep part between the first filter plate 6 and the second filter plate 61, filtering and collecting the fine impurities in the sewage. The arc groove of the flow guiding plate 62 can block the collected fine impurities, reduce the discharge of the collected fine impurities from inside and outside the stirring plate 51, and play a role in collecting the fine impurities in the sewage.

[0039] Working process: When degrading and treating rural domestic sewage, the treatment body 1 is used as the main framework of the rural domestic sewage degradation treatment device, and the sewage is introduced onto the filter rack 11 for filtration. The y-shaped filter rack 11 can filter a large number of solid impurities with strange shapes such as pesticide bottles and cans, plant roots and branches, etc. at the included angle. As the output end of the servo motor 12 drives the first rotating roller 13 to rotate, multiple rake frames 14 on the first rotating roller 13 respectively pass through the V-shaped grooves of the filter rack 11 to fish out the solid impurities in the sewage. As the output end of the servo motor 12 continues to rotate, the rake frames 14 turn the fished-out solid impurities to the blanking collection place, removing the solid impurities in the rural sewage. The sewage after removal falls into the degradation component, and adding a degradation agent to the sewage for multi-stage treatment and degradation operations can play a role in pre-treating the rural domestic sewage and improving the degradation treatment effect of the rural domestic sewage; when fishing out the solid impurities with strange shapes in the rural domestic sewage, the filter rack 11 is used to filter out the solid impurities. The F-shaped rake frames 14 rotate along with the first rotating roller 13 to fish out the solid impurities filtered on the filter rack 11. The solid impurities are temporarily stored between the two short rods of the F-shaped rake frames 14 and transported to the blanking place, playing a role in transporting the solid impurities. At the same time, some solid impurities are stuck in the V-shaped grooves of the filter rack 11. Multiple cutting knives 21 are fixed at the included angles of the rake frames 14. As the rake frames 14 approach and fit with the filter rack 11, the cutting knives 21 cut the stuck solid impurities, improving the collection effect of the solid impurities;

[0040] When the rake frames 14 rotate along with the first rotating roller 13 to fish out the solid impurities in the sewage on the filter rack 11, the solid impurities are transported to the blanking place as the rake frames 14 rotate. As the rake frames 14 rotate and tilt, the solid impurities fall from the rake frames 14 onto the guide plate 3. The two second side baffles 31 block the solid impurities falling on the guide plate 3, making the solid impurities be guided to fall to the blanking place for collection and temporary storage, playing a role in guiding and collecting the solid impurities. At the same time, the long strip grooves on the guide plate 3 can scrape the solid impurities remaining on the rake frames 14, reducing the adhesion of some impurities to the rake frames 14;

[0041] When degrading the pretreated rural domestic sewage, the first filter partition plate 41 and the second filter partition plate 42 cooperate to divide the interior of the degradation tank 4 into three storage pools, namely a degradation pool, a recovery pool and a garbage pool. The degradation pool is located at the bottom of the treatment body 1. The pretreated rural domestic sewage falls from the filter rack 11 into the degradation pool. A degradation agent is added to the degradation pool for precipitation and degradation. As the sewage continues to be injected, the water in the degradation pool flows into the recovery pool through three rows of overflow holes on the first filter partition plate 41. The water in the recovery pool is relatively cleaner than that in the other two pools. A water pump can be used to pump out the water inside for recovery treatment. The garbage pool is used to collect the solid impurities guided and dropped by the guide plate 3. A row of overflow holes opened on the second filter partition plate 42 is used to prevent the water level in the recovery pool from being too high, playing a role in the hierarchical degradation treatment of rural domestic sewage; when the rural domestic sewage falls into the degradation tank 4 for degradation treatment after pretreatment, the output end of the servo motor 12 is used to drive the first rotating roller 13 to rotate. The first rotating roller 13 synchronously drives the second rotating roller 5 connected by the first belt to rotate. A plurality of stirring plates 51 stir the sewage inside the degradation tank 4 as the second rotating roller 5 rotates, improving the mixing effect of the degradation agent and the sewage. At the same time, the second belt connects the two second rotating rollers 5, enabling a plurality of second rotating rollers 5 to rotate simultaneously when one second rotating roller 5 rotates, improving the stirring effect on the sewage inside the degradation tank 4; when the solid impurities in the sewage are pretreated, the fine impurities in the sewage subsequently fall into the interior of the degradation tank 4. Collection grooves are opened on the stirring plates 51, and the first filter mesh plate 6 and the second filter mesh plate 61 are respectively fixed on both sides of the collection groove. As the second rotating roller 5 drives a plurality of stirring plates 51 to rotate, the sewage is filtered through the first filter mesh plate 6 and the second filter mesh plate 61. Part of the sewage enters the space between the first filter mesh plate 6 and the second filter mesh plate 61 through the opening formed at the second filter mesh plate 61 for further filtration. The guide plate 62 guides the sewage. Under the influence of centrifugal force, some of the filtered impurities in the sewage are collected between the first filter mesh plate 6 and the second filter mesh plate 61, playing a role in cleaning the fine impurities in the sewage; when degrading the pretreated rural domestic sewage, as the stirring plates 51 rotate with the second rotating roller 5, part of the sewage passes through the opening at the second filter mesh plate 61 and enters the space between the first filter mesh plate 6 and the second filter mesh plate 61. Relying on the guiding of the top curved surface of the guide plate 62, the sewage enters the deep part between the first filter mesh plate 6 and the second filter mesh plate 61 to filter and collect the fine impurities in the sewage. The arc-shaped groove of the guide plate 62 can block the collected fine impurities, reducing the discharge of the collected fine impurities from inside and outside the stirring plates 51, playing a role in collecting the fine impurities in the sewage;

[0042] When degrading the pretreated rural domestic sewage, the sealing plug 71 is opened to add a degradation agent into the storage tank 7. The degradation agent is fed down to the flow control mechanism through multiple diversion pipes 72. As the flow control mechanism controls the feeding of the degradation agent, the output end of the servo motor 12 drives the first rotating roller 13 to rotate. The first rotating roller 13 triggers the flow control mechanism to intermittently add the degradation agent into the degradation tank 4, playing a role in intermittently adding the degradation agent into the degradation tank 4. When controlling the flow of the degradation agent fed at multiple diversion pipes 72, the first rotating roller 13 rotates along with the output end of the servo motor 12 to drive the transmission component to move. The transmission component drives the fixed frame 82 to slide up and down. When the fixed frame 82 slides down, multiple sealing plates 81 slide down synchronously with the fixed frame 82. At this time, the feeding channel of the diversion pipe 72 is opened, and the degradation agent falls from the flow control plate 8 into the mixed sewage inside the degradation tank 4. When the fixed frame 82 slides up, multiple sealing plates 81 slide up synchronously with the fixed frame 82. At this time, the feeding channel of the diversion pipe 72 is blocked by the upward sliding of the sealing plate 81, and the degradation agent is blocked inside the diversion pipe 72, playing a role in controlling and blocking the feeding of the degradation agent. When controlling the up and down sliding of the fixed frame 82, the first rotating roller 13 rotates along with the output end of the servo motor 12, and the convex block 92 rotates synchronously with the first rotating roller 13. When the convex block 92 approaches the arc end of the sliding frame 91, the convex block 92 squeezes the arc end of the sliding frame 91, causing the sliding frame 91 to slide down along the inner wall of the fixed block 9, and the sliding frame 91 squeezes the elastic member inside the fixed block 9 to contract and be stressed. The sliding frame 91 synchronously drives the fixed frame 82 to slide down to open the blockage at the diversion pipe 72. When the convex block 92 rotates away from the arc end of the sliding frame 91 along with the first rotating roller 13, the elastic member inside the fixed block 9 rebounds elastically, and the elastic member squeezes the sliding frame 91 to slide up. The sliding frame 91 synchronously drives the fixed frame 82 to slide up to block the diversion pipe 72, playing a role in driving the fixed frame 82 to slide up and down.
