The main structure of the live sewage degradation treatment device introduces sewage into the filter frame 11 for filtration. The Y-shaped filter frame 11 can filter a large number of solid impurities with strange shapes such as pesticide bottles and cans, plant roots and branches at the angle. As the output end of the servo motor 12 drives the No. 1 rotating roller 13 to rotate, multiple rake frames 14 on the No. 1 rotating roller 13 respectively pass through the V-shaped grooves of the filter frame 11 to salvage solid impurities in the sewage. As the output end of the servo motor 12 continues to rotate, the rake frames 14 flip the salvaged solid impurities to the unloading collection point, and the solid impurities in the rural sewage are removed. The removed sewage falls into the degradation component, and degradation agents are added to the sewage for multi-stage treatment and degradation operations, which plays a role in pre-treating rural domestic sewage and improving the degradation treatment effect of rural domestic sewage.

The solid impurities are temporarily stored between the two short rods of the F-shaped rake frame 14 and transported to the unloading place, which plays a role in transporting the solid impurities. At the same time, some solid impurities are stuck in the V-shaped groove of the filter frame 11. A plurality of cutting knives 21 are fixed at the angle of the rake frame 14. As the rake frame 14 and the filter frame 11 are close to each other, the cutting knife 21 cuts the stuck solid impurities, thereby improving the collection effect of the solid impurities.

At the same time, the long groove on the guide plate 3 can scrape the solid impurities remaining on the rake frame 14, reducing the adhesion of some impurities to the rake frame 14.

[0032] The degradation component includes a degradation box 4, a No. 1 filter baffle 41 and a No. 2 filter baffle 42; the degradation box 4 is fixedly connected to the bottom end of the treatment body 1; the No. 1 filter baffle 41 is fixedly connected to the inner wall of the degradation box 4, the No. 1 filter baffle 41 is provided with three rows of overflow holes, and the No. 1 filter baffle 41 is located in the middle of the degradation box 4; the No. 2 filter baffle 42 is fixedly connected to the inner wall of the degradation box 4, the No. 2 filter baffle 42 is provided with a row of overflow holes, and the No. 2 filter baffle 42 is located in the middle between the inner wall of the degradation box 4 and the No. 1 filter baffle 41; when the pre-treated rural domestic sewage is degraded, the No. 1 filter baffle 41 and the No. 2 filter baffle 42 cooperate to separate the internal of the degradation box 4 There are 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 pre-treated rural domestic sewage falls from the filter frame 11 into the degradation pool. Degradation agents are added to the degradation pool for precipitation and degradation. With the continuous injection of sewage, the water in the degradation pool flows into the recovery pool from the three rows of overflow holes on the No. 1 filter baffle 41. The water in the recovery pool is 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 down by the guide plate 3. The row of overflow holes on the No. 2 filter baffle 42 is used to prevent the water level in the recovery pool from being too high, thereby playing a role in graded degradation treatment of rural domestic sewage.

[0034] A collecting groove is provided on the plurality of stirring plates 51; a No. 1 filter screen plate 6 and a No. 2 filter screen plate 61 are fixedly connected on the plurality of stirring plates 51 and located on both sides of the collecting groove, and the length of the No. 2 filter screen plate 61 is shorter than the length of the No. 1 filter screen plate 6; a guide plate 62 is fixedly connected on the No. 1 filter screen plate 6 and located between the No. 1 filter screen plate 6 and the No. 2 filter screen plate 61; after the solid impurities in the sewage are pre-treated, the fine impurities in the sewage fall into the interior of the degradation box 4, a collecting groove is provided on the stirring plate 51, and the No. 1 filter screen plate is fixedly connected to the No. 1 filter screen plate 6. 6 and No. 2 filter screen plates 61 are fixed on both sides of the collecting tank respectively. As the No. 2 rotating roller 5 drives the multiple stirring plates 51 to rotate, the sewage is filtered from the No. 1 filter screen plate 6 and the No. 2 filter screen plate 61, and part of the sewage will enter the No. 1 filter screen plate 6 and the No. 2 filter screen plate 61 from the opening formed at the No. 2 filter screen plate 61 for filtration. The guide plate 62 guides the sewage. Under the influence of centrifugal force, part of the impurities filtered in the sewage will be collected between the No. 1 filter screen plate 6 and the No. 2 filter screen plate 61, which plays a role in cleaning the fine impurities in the sewage.

[0035] like Figure 1 , Figure 2 and Figure 6 As shown, the outer wall of the treatment body 1 is fixedly connected to a storage box 7; a sealing plug 71 is inserted on the storage box 7; a plurality of guide tubes 72 are fixedly connected to the inner wall of the treatment body 1 at an angle, and the plurality of guide tubes 72 are connected to the bottom of the storage box 7; a flow control mechanism is provided at one end of the treatment body 1 near the guide tube 72, and the flow control mechanism is used to control and block the degradation agent inside the guide tube 72; when the pre-treated rural domestic sewage is degraded, the sealing plug 71 is opened to add the degradation agent into the storage box 7, and the degradation agent is discharged to the flow control mechanism along the plurality of guide tubes 72, and as the flow control mechanism controls the discharge of the degradation agent, as the output end of the servo motor 12 drives the No. 1 rotating roller 13 to rotate, the No. 1 rotating roller 13 triggers the flow control mechanism to intermittently add the degradation agent to the inside of the degradation box 4, thereby playing the role of intermittently adding the degradation agent to the degradation box 4.

[0036] The flow control mechanism includes a flow control plate 8, a blocking plate 81, a fixing frame 82 and a transmission assembly; the flow control plate 8 is fixedly connected to the inside of the processing body 1, and the flow control plate 8 is located at the end of the guide tube 72 away from the storage box 7; a plurality of the blocking 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 wall of the plurality of blocking plates 81; the transmission assembly is arranged on the fixing frame 82, and the transmission assembly is used to drive the fixing frame 82 to slide; when the degradation agent discharged from the plurality of guide tubes 72 is controlled, the first rotating roller 13 is used to rotate along with the servo motor 12 The output end rotates to drive the transmission component to move, and the transmission component drives the fixed frame 82 to slide up and down. When the fixed frame 82 slides down, multiple blocking plates 81 slide down synchronously with the fixed frame 82. At this time, the unloading channel of the guide pipe 72 is opened, and the degradation agent falls from the flow control plate 8 to the mixed sewage inside the degradation box 4. When the fixed frame 82 slides up, multiple blocking plates 81 slide up synchronously with the fixed frame 82. At this time, the unloading channel of the guide pipe 72 is blocked by the blocking plate 81, and the degradation agent is blocked in the guide pipe 72, which plays a role in controlling and blocking the unloading of the degradation agent.

[0037] The transmission assembly includes a fixed block 9, a sliding frame 91 and a protrusion 92; the fixed 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 fixed block 9 through an elastic member, the top of the sliding frame 91 is set in an arc, and the bottom of the sliding frame 91 is fixed to the fixed frame 82; the protrusion 92 is fixedly connected to the outer wall of the No. 1 rotating roller 13, and the protrusion 92 is correspondingly arranged with the sliding frame 91; when the fixed frame 82 is controlled to slide up and down, the No. 1 rotating roller 13 rotates with the output end of the servo motor 12, and the protrusion 92 rotates synchronously with the No. 1 rotating roller 13, and when the protrusion 92 is close to the outer wall of the No. 1 rotating roller 13, the protrusion 92 rotates synchronously with the No. 1 rotating roller 13. When approaching the arc end of the sliding frame 91, the protrusion 92 squeezes the arc end of the sliding frame 91, so that the sliding frame 91 slides down under the inner wall of the fixed block 9, and the sliding frame 91 squeezes the elastic part inside the fixed block 9 to contract and bear the force, and the sliding frame 91 simultaneously drives the fixed frame 82 to slide down and open the blockage at the guide tube 72. When the protrusion 92 rotates away from the arc end of the sliding frame 91 along with the No. 1 rotating roller 13, the elastic part inside the fixed block 9 is elastically reset, and the elastic part squeezes the sliding frame 91 to slide up, and the sliding frame 91 simultaneously drives the fixed frame 82 to slide up and block the guide tube 72, which plays a role in driving the fixed frame 82 to slide up and down.

[0038] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the top of the guide plate 62 is curved, and a circular arc groove is provided on the side of the guide plate 62 away from the second rotating roller 5; when the pre-treated rural domestic sewage is degraded, the stirring plate 51 is used to rotate with the second rotating roller 5, and part of the sewage passes through the opening at the second filter screen plate 61 and enters between the first filter screen plate 6 and the second filter screen plate 61. Relying on the guidance of the curved surface at the top of the guide plate 62, the sewage enters the deep between the first filter screen plate 6 and the second filter screen plate 61, and the fine impurities in the sewage are filtered and collected. The circular arc groove of the guide plate 62 can block the collected fine impurities, reduce the collected fine impurities from being discharged from the inside and outside of the stirring plate 51, and play a role in collecting the fine impurities in the sewage.

[0039] Working process: When rural domestic sewage is degraded and treated, the treatment body 1 is used as the main structure of the rural domestic sewage degradation treatment device, and the sewage is introduced into the filter frame 11 for filtration. The Y-shaped filter frame 11 can filter a large number of pesticide bottles, plant roots and branches and other odd-shaped solid impurities at the angle. As the output end of the servo motor 12 drives the No. 1 rotating roller 13 to rotate, the multiple rake frames 14 on the No. 1 rotating roller 13 respectively pass through the V-shaped groove of the filter frame 11 to salvage the solid impurities in the sewage. As the output end of the servo motor 12 continues to rotate, the rake frame 14 flips the salvaged solid impurities to the unloading collection point, and the solid impurities in the rural sewage are removed. The removed sewage falls into the degradation component, and the degradation agent is added to the sewage for multi-stage treatment. The degrading operation can be performed, which plays a role in pre-treating rural domestic sewage and improving the degradation treatment effect of rural domestic sewage; when the odd-shaped solid impurities in the rural domestic sewage are salvaged, the filter frame 11 is used to filter out the solid impurities, and the F-shaped rake frame 14 rotates with the No. 1 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 unloading place, which plays a role in transporting the solid impurities. At the same time, some solid impurities are stuck in the V-shaped groove of the filter frame 11. A plurality of cutting knives 21 are fixed at the angle of the rake frame 14. As the rake frame 14 and the filter frame 11 are close to each other, the cutting knives 21 cut the stuck solid impurities, thereby improving the collection effect of the solid impurities;

[0040] When the rake frame 14 rotates with the No. 1 rotating roller 13 to salvage solid impurities in the sewage on the filter frame 11, the solid impurities are transported to the unloading 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 No. 2 side baffles 31 block the solid impurities falling from the guide plate 3, so that the solid impurities are guided to fall to the unloading place for collection and temporary storage, which plays a role in guiding and collecting the solid impurities. At the same time, the long grooves 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;

[0041] When the pre-treated rural domestic sewage is degraded, the first filter baffle 41 and the second filter baffle 42 cooperate to divide the interior of the degradation box 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 pre-treated rural domestic sewage falls from the filter frame 11 into the degradation pool. The degradation agent is added to the degradation pool for precipitation and degradation. With the continuous injection of sewage, the water in the degradation pool flows into the recovery pool from the three rows of overflow holes on the first filter baffle 41. The water in the recovery pool is cleaner than the other two pools, and a water pump can be used to pump out the water inside for recycling. The garbage pool is used to collect the solid impurities guided by the guide plate 3. A row of overflow holes on the No. 2 filter baffle 42 is used to prevent the water level in the recovery pool from being too high, which plays a role in the graded degradation treatment of rural domestic sewage; when the rural domestic sewage falls into the degradation box 4 for degradation treatment after pretreatment, the output end of the servo motor 12 is used to drive the No. 1 rotating roller 13 to rotate, and the No. 1 rotating roller 13 synchronously drives the No. 2 rotating roller 5 connected to the No. 1 belt to rotate, and multiple stirring plates 51 stir the sewage inside the degradation box 4 as the No. 2 rotating roller 5 rotates, thereby improving the mixing effect of the degradation agent and the sewage. At the same time, the No. 2 belt connects the two No. 2 rotating rollers 5, and can synchronously drive multiple No. 2 rotating rollers 5 to rotate simultaneously when one No. 2 rotating roller 5 rotates, thereby improving the The agitation effect of the sewage in the degradation box 4; when the solid impurities in the sewage are pre-treated, the fine impurities in the sewage fall into the interior of the degradation box 4, a collection tank is opened on the agitation plate 51, and the No. 1 filter screen plate 6 and the No. 2 filter screen plate 61 are respectively fixed on both sides of the collection tank, as the No. 2 rotating roller 5 drives the multiple agitation plates 51 to rotate, the sewage is filtered from the No. 1 filter screen plate 6 and the No. 2 filter screen plate 61, and part of the sewage will enter the No. 1 filter screen plate 6 and the No. 2 filter screen plate 61 from the opening formed at the No. 2 filter screen plate 61 for filtration, and the guide plate 62 guides the sewage, and under the influence of centrifugal force, part of the impurities filtered in the sewage will be collected in the No. 1 filter screen plate 6 and The second filter screen plate 61 plays a role in cleaning fine impurities in the sewage; when the pre-treated rural domestic sewage is degraded, the stirring plate 51 is used to rotate with the second rotating roller 5, and part of the sewage passes through the opening at the second filter screen plate 61 and enters between the first filter screen plate 6 and the second filter screen plate 61. Relying on the guidance of the curved surface at the top of the guide plate 62, the sewage enters the deep between the first filter screen plate 6 and the second filter screen plate 61, and the fine impurities in the sewage are filtered and collected. The arc groove of the guide plate 62 can block the collected fine impurities, reduce the collected fine impurities from the inside and outside of the stirring plate 51, and play a role in collecting fine impurities in the sewage;

[0042] When the pre-treated rural domestic sewage is degraded, the sealing plug 71 is opened to add the degradation agent into the storage box 7, and the degradation agent is discharged to the flow control mechanism along the multiple guide tubes 72. As the flow control mechanism controls the discharge of the degradation agent, as the output end of the servo motor 12 drives the No. 1 rotating roller 13 to rotate, the No. 1 rotating roller 13 triggers the flow control mechanism to intermittently add the degradation agent to the inside of the degradation box 4, which plays a role in intermittently adding the degradation agent to the degradation box 4; when the degradation agent discharged from the multiple guide tubes 72 is controlled, the No. 1 rotating roller 13 is used to rotate along with the output end of the servo motor 12 to drive the transmission component to move, and the transmission component drives the fixed frame 82 to slide up and down. When the fixed frame 82 slides down, the multiple blocking plates 81 slide down synchronously with the fixed frame 82. At this time, the discharge channel of the guide tube 72 is opened, and the degradation agent falls from the flow control plate 8 to the mixed sewage inside the degradation box 4. When the fixed frame 82 slides up, the multiple blocking plates 81 slide up synchronously with the fixed frame 82. At this time, the material discharge channel of the guide tube 72 is blocked by the blocking plate 81 sliding upward, and the degradation agent is blocked in the guide tube 72, which plays a role in controlling the blocking of the material discharge of the degradation agent; when the fixed frame 82 is controlled to slide up and down, the first rotating roller 13 rotates with the output end of the servo motor 12, and the protrusion 92 rotates synchronously with the first rotating roller 13. When the protrusion 92 approaches the arc end of the sliding frame 91, the protrusion 92 squeezes the arc end of the sliding frame 91, so that the sliding frame 91 slides down under the fixed block 9, and the sliding frame 91 squeezes the elastic part inside the fixed block 9 to shrink and bear the force, the sliding frame 91 synchronously drives the fixed frame 82 to slide down and open the blockage at the guide tube 72, when the protrusion 92 rotates with the arc end of the first rotating roller 13 away from the sliding frame 91, the elastic part inside the fixed block 9 is elastically reset, the elastic part squeezes the sliding frame 91 to slide up, and the sliding frame 91 synchronously drives the fixed frame 82 to slide up and block the guide tube 72, which plays a role in driving the fixed frame 82 to slide up and down.
