Description

Technical Field

[0001] The present invention belongs to the technical field of sludge treatment, and specifically relates to a waste treatment device for agricultural green planting. Background Art In the agricultural green planting system, sludge waste mainly comes from livestock and poultry manure treatment, aquaculture pond cleaning, farmland irrigation return water sedimentation and other links. These sludges are rich in organic matter, nitrogen, phosphorus, potassium and other nutrients. If properly treated, they can be converted into high-quality organic fertilizers or soil conditioners, achieving "turning waste into treasure". However, untreated sludge has a water content of up to 80%-90%, with problems such as large volume, easy to rot and stink, and spread of pathogenic bacteria. Direct application will cause soil compaction and water pollution. Therefore, drying treatment has become the primary link in the resource utilization of sludge. Currently, when treating sludge, hot air drying treatment equipment is generally used. Due to its high treatment efficiency and wide applicability, it is widely used in the field of sludge drying. Its principle is that hot air contacts the surface of the sludge, and water is evaporated by convective heat transfer.

[0003] After the sludge is dried, harmful substances such as heavy metals and pathogenic bacteria can be eliminated through chemical conditioning, biodegradation and other treatment methods, and then mixed with other agricultural wastes, and the properties are changed through physical processing, and finally converted into raw materials that can be used for soil improvement, fertilizer production or energy manufacturing, and re-invested in the agricultural production link to form a green recycling system.

[0004] However, the existing hot air drying equipment uses a single hot air convection method, and the heat can only be transferred to the surface of the sludge. When the surface water evaporates rapidly, the sludge will form a dense hardening layer, like a "shell" wrapping the inside. This hardening layer not only hinders the further inward conduction of heat, but also seriously inhibits the outward diffusion of internal water, resulting in a high water content inside. Even if the drying time is extended, it is difficult to penetrate the hardening layer, and finally an unqualified product with "dry outside and wet inside" is formed, which cannot meet the water content requirements for subsequent resource utilization.

[0014] The beneficial effects of the present invention are as follows: 1. In the waste treatment device for agricultural green planting according to the present invention, since the retaining ring rotates counterclockwise with the first mesh cylinder, the pressure roller in contact with the retaining ring will be driven to rotate counterclockwise under the friction of the retaining ring. When the first mesh cylinder drives the sludge past the counterclockwise rotating pressure roller, the pressure roller will extrude the sludge, thereby changing the thickness of the sludge adhering to the inner circle of the first mesh cylinder, squeezing the sludge thinner. During the process of squeezing the sludge thinner, the hardened layer formed on the surface of the sludge will be extruded, and the un-dried sludge inside will be extruded. At the same time, in cooperation with the flowing hot air, the flowing hot air can contact the extruded un-dried sludge, thereby taking away the moisture in the sludge, accelerating the sludge drying process, and at the same time making the thickness of the sludge passing through the pressure roller uniform, avoiding the situation that the sludge adhering to the inner circle of the first mesh cylinder has uneven thickness, resulting in uneven drying; at the same time, during the process of the pressure roller extruding the sludge, part of the water in the sludge can be extruded and then thrown out under the action of centrifugal force, thereby improving the drying efficiency of the sludge.

[0015] 2. In the waste treatment device for agricultural green planting according to the present invention, when all the sludge in the first mesh cylinder is completely discharged, most of the sludge will be pushed out by the auger in the second mesh cylinder, and part of the sludge will remain between the sliding plate and the auger and block the right end of the second mesh cylinder. When drying the sludge again, the hot air entering the second mesh cylinder cannot flow out from the right end of the second mesh cylinder and can only flow into the first mesh cylinder through the pores on the second mesh cylinder, so that more hot air acts on the sludge being dried, improving the utilization rate of the hot air; if the pores on the second mesh cylinder are blocked by the sludge, the amount of hot air entering the second mesh cylinder remains unchanged, which will increase the air pressure in the second mesh cylinder. When the pressure increases, the pores of the second mesh cylinder will be unblocked, preventing the second mesh cylinder from being blocked and unable to discharge the hot air. At the same time, during the process of the auger pushing the sludge to squeeze each other, the sludge can be compressed. If there is still residual moisture in the sludge, this part of the water can be extruded.

[0016] 3. In the waste treatment device for agricultural green planting according to the present invention, since the rotating roller also contacts the retaining ring, the rotating retaining ring will push the rotating roller to rotate counterclockwise, and the rotating roller will drive the conical plate to rotate. When the thinned sludge passes through the rotating roller, the rotating roller will cut the sludge layer through the conical plate. When the sludge layer is cut, the cut surface of the sludge will contact the hot air, thereby accelerating the sludge drying process. When the cut sludge passes through the roller, under the action of the centrifugal force of the first mesh cylinder, the cut sludge will be attached to the inner circle of the first mesh cylinder again, and then be driven to rotate again by the first mesh cylinder. When it rotates to the position of the pressure roller again, the pressure roller will extrude the sludge again, and then be cut by the conical plate on the roller again. During this process, the sludge can be cyclically extruded and cut, thereby continuously changing the shape of the sludge, making the sludge contact the hot air, and thus improving the sludge drying process.

[0022] During implementation, when treating sludge, first pump the sludge into the feeding bin 22. When the feeding bin 22 is filled with sludge, at this time, control the electric push rod 23 to extend. The extended electric push rod 23 will push the material plate 21 to gradually move downward. The downward-moving material plate 21 will drive the sludge pump and the mud outlet pipe 22 to move downward. During the downward movement of the mud outlet pipe 22, it will gradually contact the rotating plate 19. Since the rotating plate 19 is hinged in the feeding port 18 through a rotating shaft and a torsion spring, the downward-moving mud outlet pipe 22 will push the rotating plate 19 to gradually rotate towards the inside of the first mesh cylinder 12, and the mud outlet pipe 22 will gradually extend into the first mesh cylinder 12. When the mud outlet pipe 22 extends into the first mesh cylinder 12, the sludge pump works, so as to pump the sludge above the material plate 21 into the first mesh cylinder 12. Since the mud outlet pipe 22 is a metal elbow pipe, when the mud outlet pipe 22 discharges materials, the sludge will be sprayed towards the inner circle of the first mesh cylinder 12. When the sludge enters the first mesh cylinder 12, control the sludge pump to stop working, and at the same time control the first electric push rod 23 to drive the material plate 21, the sludge pump and the mud outlet pipe 22 to return to the initial state. When the mud outlet pipe 22 extends out of the feeding port 18, the rotating plate 19 returns to the initial state under the action of the torsion spring, and then the sludge can be treated; In the implementation process, first, the intake pipe 34 is connected to the external conduit, and hot air is introduced into the second mesh cylinder 3. Subsequently, the servo motor 16 is controlled to drive the gear 17 to rotate. The rotating gear 17 will drive the toothed ring 15 to rotate, and the first mesh cylinder 12 will rotate counterclockwise following the toothed ring 15. During the rotation of the first mesh cylinder 12, the first mesh cylinder 12 will generate centrifugal force. Under the action of the centrifugal force, the sludge will adhere to the inner wall of the first mesh cylinder 12, and the water in the sludge will be thrown out through the pores of the first mesh cylinder 12 under the action of the centrifugal force, thus realizing the drying process of separating liquid from sludge. During the process of sludge treatment, the hot air entering the second mesh cylinder 3 will flow spirally along the auger 42. During the flow of the hot air, it will flow out from the pores of the second mesh cylinder 3, and the flowing-out hot air will enter the first mesh cylinder 12, thereby drying the sludge in the second mesh cylinder 3. When the water separates from the first mesh cylinder 12, the water will fall into the treatment chamber 1. At the same time, the hot air will gradually fill the first mesh cylinder 12 and flow into the treatment chamber 1. Subsequently, the water and the hot air will be discharged through the outlet pipe 11 for collection.

[0023] In the implementation process, since the hot air first contacts the surface of the sludge, a dense hardened layer will be formed on the surface of the sludge, which will affect the diffusion of the moisture inside the sludge. At this time, the hydraulic cylinders 33 on the upper and lower sides of the fixed ring 32 are controlled to work, that is, the upper hydraulic cylinder 33 is controlled to extend, and the lower hydraulic cylinder 33 is controlled to contract, thereby driving the fixed ring 32 and the second mesh cylinder 3 to move downward. The downward-moving second mesh cylinder 3 will drive the pressure roller 35 to move downward. The downward-moving pressure roller 35 will gradually contact the retaining ring 13. At the same time, the pressure roller 35 will squeeze the sludge that adheres to the inner ring of the first mesh cylinder 12. Since the retaining ring 13 rotates counterclockwise following the first mesh cylinder 12, the pressure roller 35 in contact with the retaining ring 13 will be driven to rotate counterclockwise under the friction of the retaining ring 13. When the first mesh cylinder 12 drives the sludge to pass through the counterclockwise-rotating pressure roller 35, the pressure roller 35 will squeeze the sludge, thereby changing the thickness of the sludge that adheres to the inner ring of the first mesh cylinder 12 and squeezing the sludge thinner. During the process of squeezing the sludge thinner, the hardened layer formed on the surface of the sludge will be squeezed, and the un-dried sludge inside will be extruded. At the same time, in cooperation with the flowing hot air, the flowing hot air can contact the extruded un-dried sludge, thereby taking away the moisture in the sludge and accelerating the sludge drying process. At the same time, it can make the thickness of the sludge passing through the pressure roller 35 uniform, avoiding the situation that the sludge that adheres to the inner ring of the first mesh cylinder 12 has uneven thickness, resulting in uneven drying. At the same time, during the process of the pressure roller 35 squeezing the sludge, part of the water in the sludge can be extruded, and then will be thrown out under the action of the centrifugal force, thereby improving the drying efficiency of the sludge. During the process of drying sludge, since the side plates 36 on both sides of the feeding bin 2 are mesh plates, the water in the sludge stored in the feeding bin 2 will naturally seep out through the mesh holes. The seeping water will enter the current-limiting plate 24 and then flow into the treatment bin 1 through the leakage trough 25. Since the feeding bin 2 is fixedly connected with inclined plates 26 on both sides of the treatment bin 1, the water flowing in from the leakage trough 25 will flow along the inclined plates 26 and reach the bottom of the treatment bin 1. During this process, part of the water in the sludge in the feeding bin 2 can be naturally seeped out first, thereby reducing the water content in the sludge. When treating the sludge, the process of sludge drying can be accelerated; During the implementation process, when the sludge drying is completed, continue to control the hydraulic cylinder 33 to work, that is, control the upper hydraulic cylinder 33 to contract and the lower hydraulic cylinder 33 to extend, which will drive the fixing ring 32 and the second mesh cylinder 3 to move upward. At the same time, control the motor 39 to drive the feeding plate 38 to rotate. The rotating feeding plate 38 will rotate in the feeding trough 37. After the feeding plate 38 rotates, the feeding plate 38 will tilt upward. When the first mesh cylinder 12 gradually moves upward, it will drive the rotated feeding plate 38 to gradually move upward. When the rotated feeding plate 21 gradually contacts the sludge fitting in the inner circle of the first mesh layer, the rotated feeding plate 38 will scrape the sludge. Since the sludge rotates counterclockwise following the first mesh cylinder 12, the sludge will gradually be scraped into the feeding trough 37 and then enter the inside of the second mesh cylinder 3. As the second mesh cylinder 3 gradually drives the feeding plate 38 to move upward, when the feeding plate 38 contacts the inner circle of the first mesh cylinder 12, at this time, the sludge located in the inner circle of the first mesh cylinder 12 is completely scraped into the second mesh cylinder 3. During the process of the sludge being scraped into the second mesh cylinder 3, control the first motor 41 to rotate, which will drive the auger 42 to rotate. The rotating auger 42 will push the dried sludge to move, so that the sludge is discharged from the second mesh cylinder 3. The hot air flowing along the auger 42 will dry the sludge falling into the second mesh cylinder 3 again, thereby further improving the drying effect of the sludge. When all the sludge is discharged, continue to add sludge into the first mesh cylinder 12, and the drying can be carried out again.

[0024] As an implementation manner of the present invention, guide rods 43 are uniformly arranged on the right side of the second mesh cylinder 3, and the guide rods 43 are fixedly connected to the adjacent fixing rings 32; A sliding disk 44 is slidably arranged on the guide rods 43 together; a sealing plate 45 is installed at the end of the guide rods 43; a spring is arranged between the sealing plate 45 and the sliding disk 44, and the spring is sleeved on the guide rods 43; in the initial state, the sliding disk 44 fits with the opening of the second mesh cylinder 3 under the action of the spring; A distance is left between the auger 42 and the sliding disk 44; the mounting plate 4 is located inside the second mesh cylinder 3 and is slidably connected to the second mesh cylinder 3; a U-shaped plate 46 is fixedly installed at the left end of the second mesh cylinder 3; a cylinder 47 is fixedly connected to the U-shaped plate 46, and the other side of the cylinder 47 is fixedly installed on the first motor 41; In this embodiment, a second motor 48 is fixedly installed on the sliding disk 44; The output shaft of the second motor 48 passes through the sliding disk 44 and is fixedly connected with uniformly arranged push plates 49; the push plates 49 are located in the second mesh cylinder 3 in the initial state; In this embodiment, threads are provided on the side of the guide rod 43 that contacts the sealing plate 45; The sealing plate 45 is a threaded ring and is engaged on the guide rod 43 by threads; a pin shaft is inserted at the end of the guide rod 43; During implementation, during the rotation of the auger 42, the sludge will be gradually pushed to move in the second mesh cylinder 3. Since there is a distance between the auger 42 and the sliding disk 44, when the sludge is pushed between the sliding disk 44 and the auger 42, the sludge will remain between the sliding disk 44 and the auger 42. As the sludge gradually increases, the sludge between the sliding disk 44 and the auger 42 will be squeezed against each other, gradually compacted, and gradually fill the space between the sliding disk 44 and the auger 42. Since the auger 42 continuously pushes the sludge, more sludge will continue to enter between the sliding disk 44 and the auger 42, thereby pushing the compacted sludge towards the sliding disk 44 side and pushing the sliding disk 44 to move along the guide rod 43. During the movement of the sliding disk 44, the spring will be compressed and the sliding disk 44 will gradually move away from the second mesh cylinder 3; at the same time, control the second motor 48 to rotate. The rotating second motor 48 will drive the push plates 49 to rotate, and the rotating push plates 49 will push out the sludge that pushes the sliding disk 44 to move, thereby preventing the sludge from continuously pushing the sliding disk 44 to move, thus realizing the process of discharging the dried sludge; During the implementation process, when all the sludge in the first mesh cylinder 12 is completely discharged, most of the sludge in the second mesh cylinder 3 will be pushed out by the auger 42, and part of the sludge will remain between the sliding disk 44 and the auger 42 and block the right end of the second mesh cylinder 3. When the sludge is dried again, the hot air entering the second mesh cylinder 3 cannot flow out from the right end of the second mesh cylinder 3 and can only flow into the first mesh cylinder 12 through the pores on the second mesh cylinder 3, so that more hot air acts on the sludge being dried, improving the utilization rate of the hot air; if the pores on the second mesh cylinder 3 are blocked by the sludge, the amount of hot air entering the second mesh cylinder 3 remains unchanged, which will increase the air pressure in the second mesh cylinder 3. When the pressure increases, the pores of the second mesh cylinder 3 will be dredged to prevent the second mesh cylinder 3 from being blocked and the hot air from being unable to be discharged. At the same time, during the process of the auger 42 pushing the sludge to be squeezed against each other, the sludge can be compressed. If there is still residual moisture in the sludge, this part of the water can be squeezed out; During the implementation process, since the sealing plate 45 is engaged with the guide rod 43 by threads, after all the sludge drying is completed, first remove the sealing plate 45 from the guide rod 43, then remove the sliding disk 44 from the guide rod 43, and then control the cylinder 47 to extend. The extended cylinder 47 will push the first motor 41 and the mounting plate 4 to move to the right in the second drum 3, thereby driving the auger 42 to move to the right. The auger 42 moving to the right will push the sludge located between the sliding disk 44 and the auger 42, so as to push the remaining sludge out of the second drum 3.

[0025] As an implementation manner of the present invention, an arc-shaped scraper 5 is provided below the pressing roller 35, and the arc-shaped scraper 5 is located between two retaining rings 13; The arc-shaped scraper 5 is fixedly connected to the second drum 3 through a connecting plate 51; In this implementation manner, a rotating roller 52 is provided on the right side of the pressing roller 35, and the length of the rotating roller 52 is the same as the length of the pressing roller 35; Side plates 36 are rotatably arranged on both sides of the rotating roller 52, and the other side of the side plates 36 is fixedly connected to the surface of the second drum 3; uniformly arranged conical plates 53 are fixedly connected to the outer circumferential surface of the rotating roller 52, and the conical plates 53 are in contact with the arc-shaped scraper 5; the conical plates 53 are located between two retaining rings 13; In this implementation manner, a slideway 311 is provided on the inner circumference of the long groove 31; Blocking layers 312 are fixedly connected to the upper and lower sides of the fixed ring 32, and the blocking layers 312 are made of rubber material; one side of the blocking layer 312 away from the fixed ring 32 is fixedly connected to the slideway 311, and both sides of the blocking layer 312 slide in the slideway 311; During implementation, when the second drum 3 drives the pressing roller 35 to move downward, it will drive the arc-shaped scraper 5 and the rotating roller 52 to move downward. When the arc-shaped scraper 5 contacts the inner circumferential surface of the first drum 12, at this time, both the pressing roller 35 and the rotating roller 52 contact the surface of the retaining ring 13. Subsequently, during the process of the first drum 12 driving the adhered sludge to rotate, the arc-shaped scraper 5 will scrape the rotating sludge. The scraped sludge will pass above the arc-shaped scraper 5. When the sludge passes through the pressing roller 35, the pressing roller 35 can extrude the passing sludge, thereby changing the thickness of the sludge layer and pressing out the moist sludge inside. During this process, it can prevent the pressing roller 35 from directly extruding the sludge on the inner circumference of the first drum 12, thereby avoiding the sludge being blocked in the pores of the first drum 12 after being extruded, and at the same time avoiding the sludge flowing out from the pores of the first drum 12 when being extruded; During the implementation process, since the rotating roller 52 also contacts the retaining ring 13, the rotating retaining ring 13 will push the rotating roller 52 to rotate counterclockwise. The rotating roller 52 will drive the conical plate 53 to rotate. When the thinned sludge passes through the rotating roller 52, the rotating roller 52 will cut off the sludge layer through the conical plate 53. After the sludge layer is cut off, the cut surface of the sludge will contact the hot air, thereby accelerating the sludge drying process. After the cut sludge passes through the roller 52, under the action of the centrifugal force of the first mesh cylinder 12, the cut sludge will be attached to the inner ring of the first mesh cylinder 12 again, and then be driven to rotate again by the first mesh cylinder 12. When it rotates to the position of the pressing roller 35 again, the pressing roller 35 will squeeze the sludge again, and then be cut off by the conical plate 53 on the roller 52 again. During this process, the sludge can be cyclically squeezed and cut, so that the shape of the sludge can be continuously changed, and the sludge can contact the hot air, thereby improving the sludge drying process; During the implementation process, due to the existence of the baffle layer 312, the long groove 31 can be blocked to prevent the hot air in the treatment chamber 1 from flowing out of the long groove 31. At the same time, since one side of the baffle layer 312 away from the fixed ring 32 is fixedly connected in the slideway 311, when the fixed ring 32 moves up or down, it will push the baffle layer 312 to move, causing the baffle layer 312 to be compressed or stretched. Therefore, after the fixed ring 32 moves, the long groove 31 can still be blocked.
