Description

Technical Field

[0001] The present invention relates to the technical field of domestic waste treatment, and particularly to a corrosion-resistant scraper conveyor device and method for domestic waste treatment. Background Art

[0002] Solid waste generated by people in daily life or activities providing services for daily life, as well as solid waste regarded as domestic waste as stipulated by laws and administrative regulations. A scraper conveyor device refers to a device that uses a scraper chain to tow and transport bulk materials in a trough. According to the layout and structure of the chute of the scraper conveyor, it can be divided into two types: side-by-side type and overlapping type. According to the number and layout of the chains, it can be divided into four types: single chain, double side chain, double center chain, and triple chain. At present, in the use of some existing scraper conveyor devices, due to poor heat insulation, cold air from the outside enters the device, which not only causes the hot air to condense and corrode the device, but also causes the ash residue to solidify when it meets the cold, thereby reducing the service life of the device. At the same time, the later maintenance is also very cumbersome. Summary of the Invention

[0003] The purpose of the present invention is to provide a corrosion-resistant scraper conveyor device and method for domestic waste treatment, so as to solve the problem proposed in the above background art that in the use of some existing scraper conveyor devices, due to poor heat insulation, cold air from the outside enters the device, which not only causes the hot air to condense and corrode the device, but also causes the ash residue to solidify when it meets the cold, thereby reducing the service life of the device. At the same time, the later maintenance is also very cumbersome. Through this solution, not only can the heat loss be reduced, but also the entry of outside cold air into the device can be avoided, effectively preventing the hot air from condensing and corroding the device, thereby improving the corrosion resistance of the device and its service life. It can also prevent the ash residue from solidifying when it meets the cold and prevent it from clogging inside the device, affecting the transportation of the ash residue.

[0010] Preferably, the auxiliary mechanism includes a rotating part. Maintenance plates are connected to both ends of the horizontal conveying channel through bolts. A rotating part is fixedly connected to one end of the driven roller.

[0011] Preferably, the control end of the motor is electrically connected to an external power supply through the rotation sensor. The middle parts of the elastic sheets are respectively deformed by the second support rods. The sealing covers are respectively located outside the sliding grooves, which improves the sealing performance of the device.

[0012] Operating method of the device: Step 1: Ash scraping. After the ash residue inside the ash hopper (2) enters the horizontal conveying channel (1), the motor (6) drives the driving roller (5), the driven roller (7), the chain (8) and the scraping plate (9) to rotate. The fallen ash residue is scraped away by the moving scraping plate (9) until it falls inside the blanking pipe (3). Step 2: Automatic tension adjustment. When the chain and the driven roller are rotating, the driven roller will pull the heat insulation sliding plate to slide inside the heat insulation groove. At the same time, the adjusting plate slides on both sides of the horizontal conveying channel. The adjusting plate can drive the adjusting rod to move through the first thread sleeve and the second thread sleeve, and then the self-adaptive tension adjustment can be carried out through the adjusting rod and the spring. Step 3: Automatic blanking. The ash residue falls inside the blanking pipe through the scraping plate. When the gravity of the ash residue exceeds the set weight, one end of the second closing plate moves downward in a circular motion. At this time, the electric push rod is controlled by the travel switch to shorten, so that the counterweight block approaches the connection position of the blanking pipe and the second closing plate. At this time, the ash residue at the top of the second closing plate will be poured out of the blanking pipe. At the same time, the second closing plate can make the first connecting rod and the first closing plate rotate through the second connecting rod and the third connecting rod until one end of the first closing plate abuts against the limiting rod. At this time, both the first closing plate and the first connecting rod rotate 90 degrees, and the second closing plate also reaches the maximum opening state, so that the first closing plate and the second closing plate are in the closed and open states respectively. Step 4: Fault. When the chain inside the device breaks, the driven roller stops rotating, and the rotating part also stops rotating. The rotation sensor can remind the user that the device has a fault, and at the same time, the motor stops working. Step Five: Maintenance. The user removes the sealing cover and the maintenance plates on both sides of the horizontal conveyor, then pulls out the damaged chain and scraping plate. Next, the first sliding plate and the second sliding plate are moved to one side of the driven roller. The new chain and scraping plate are fitted with the driven roller. By rotating the threaded rod, the two groups of second sliding plates and the first sliding plate can be made to approach each other, so that the connection point between the second support rod and the first support rod moves upward. After the user rotates the threaded rod to make the first sliding plate and the second sliding plate fit together and the second support rod is on one side of the driven roller, the user pushes the two groups of first sliding plates and second sliding plates to drive the chain and the scraping plate to move until they reach one side of the driving roller, making one end of the chain and the scraping plate engage with the driving roller. At this time, the scraping plate is inside the plate groove or the anti-slip teeth are inside the tooth groove. The user controls the first support rod and the second support rod to reset. The user drives the driving roller to rotate through the motor and the chain and the scraping plate to move until one end of the chain and the scraping plate moves to the inner wall at the bottom of the horizontal conveyor. At the same time, because the chain has a certain hardness, under the action of the chain itself, one end of the chain and the scraping plate can slide on the inner wall at the bottom of the horizontal conveyor until it reaches one end of the driven roller. At this time, the user can connect the two ends of the chain, and finally reinstall and restore the device.

[0013] After the ash and slag inside the ash hopper enter the horizontal conveying channel, the driving roller, driven roller, chain, and scraping plate are powered by an electric motor. The plate groove, tooth groove, and anti-slip teeth can prevent the chain from slipping on the surfaces of the driving roller and driven roller. The fallen ash and slag are scraped away by the moving scraping plate until they fall inside the blanking pipe. When the chain and the driven roller rotate, the driven roller will pull the heat-insulating sliding plate to slide inside the heat-insulating groove. At the same time, the adjusting plate slides on both sides of the horizontal conveying channel. The adjusting plate can pull the adjusting rod to move through the first threaded sleeve and the second threaded sleeve. Then, through the adjusting rod and the spring, adaptive tension adjustment can be carried out to prevent the chain from breaking due to excessive tension, thereby affecting the normal operation of this device. The user can control the elasticity of the spring by rotating the first threaded sleeve and the second threaded sleeve, and thus can adjust the tension received by the chain, further improving the protection of the chain and the convenience of use for the user. The ash and slag fall inside the blanking pipe at the top of the second closing plate. At one end of the second closing plate, the user pushes the counterweight block to slide through the electric push rod. By changing the position of the counterweight block, the weight of the automatic blanking of this device can be controlled, that is, the collection amount of ash and slag at the top of the second closing plate. When the gravity of the ash and slag exceeds the set weight, at this time, one end of the second closing plate moves downward in a circular motion. At this time, the electric push rod is controlled by the travel switch to shorten, so that the counterweight block approaches the connection position of the blanking pipe and the second closing plate. At this time, the ash and slag at the top of the second closing plate will pour out of the blanking pipe. At the same time, the second closing plate can make the third connecting rod move through the second connecting rod. Through the third connecting rod, the first connecting rod can be rotated. At this time, the first connecting rod drives the first closing plate to rotate until one end of the first closing plate abuts against the limiting rod. At this time, both the first closing plate and the first connecting rod rotate ninety degrees, and the second closing plate also reaches the maximum opening state, so that the first closing plate and the second closing plate are respectively in the closed and open states, thereby avoiding the heat loss inside the horizontal conveying channel and the blanking pipe, and avoiding the entry of foreign cold air into the inside of this device when pouring ash and slag, thus avoiding the condensation and corrosion of hot air on this device, and further reducing the loss of the user and ensuring the normal use of this device. At the same time, through the heat-insulating cotton and protective plates arranged on the surfaces of the horizontal conveying channel and the blanking pipe, the heat loss of this device can be avoided, and the ash and slag inside this device can be prevented from caking. After pouring is completed, at this time, the electric push rod drives the counterweight block to reset. Finally, through the second connecting rod, the third connecting rod, and the first connecting rod, the first closing plate is reset. At this time, the ash and slag fall on the top of the second closing plate for collection. When the chain inside this device breaks, at this time, the driven roller stops rotating, and the rotating part also stops rotating. Through the rotating sensor, the user can be reminded that this device has a fault. At the same time, the electric motor stops working. When the user needs to repair the chain and the scraping plate, the user removes the sealing cover and the repair plates on both sides of the horizontal conveying channel, then pulls out the damaged chain and scraping plate, then moves the first sliding plate and the second sliding plate to one side of the driven roller, places the new chain and scraping plate on the surface of the driven roller, makes the chain and the scraping plate cooperate with the driven roller, and then the user rotates the threaded rod,The two sets of second sliding plates and the first sliding plate can be made to approach each other through the threaded rod, so that the connection part of the second support rod and the first support rod moves upward. At the same time, under the action of the self-return elasticity of the elastic sheet, it is more convenient for the connection part of the second support rod and the first support rod to move upward. At the same time, the movement track of the second support rod can also be limited, so that the connection part of the second support rod and the first support rod can only move upward. After the user rotates the threaded rod to make the first sliding plate and the second sliding plate fit, and makes the second support rod on one side of the driven roller, the user pushes the two sets of first sliding plates and second sliding plates to move inside the sliding groove, so as to drive the chain and the scraping plate to move through the first sliding plate and the second sliding plate until it moves to one side of the driving roller. The user makes one end of the chain and the scraping plate engage with the driving roller by pushing the first sliding plate and the second sliding plate. At this time, the scraping plate is inside the plate groove or the anti-slip teeth are inside the tooth groove. The user rotates the threaded rod to control the reset of the first support rod and the second support rod. At the same time, the travel switch is separated from the second sliding plate. At this time, the second support rod no longer abuts against the scraping plate. Then the user controls the output end of the motor to rotate slowly, drives the driving roller to rotate slowly through the motor, and the driving roller drives the chain and the scraping plate to move until one end of the chain and the scraping plate moves to the inner wall of the bottom end of the horizontal conveying channel. The rotating driving roller can make the chain and the scraping plate in a taut state. At the same time, due to the certain hardness of the chain, the chain itself can make one end of the chain and the scraping plate slide on the inner wall of the bottom end of the horizontal conveying channel until it moves to one end of the driven roller. At this time, the user can connect the two ends of the chain, so that the chain forms a loop. Finally, the device is installed and restored. This device can not only reduce the loss of heat, but also prevent the outside cold air from entering the device, effectively avoid the condensation and corrosion of the hot air on the device, thereby improving the corrosion resistance of the device and increasing the service life of the device. It can also prevent the ash slag from caking when encountering cold, prevent it from blocking inside the device and affecting the conveying of the ash slag. This device is also convenient for later maintenance and replacement work, further reducing the work difficulty of the user and improving the work efficiency of the user.

A cross plate 17 is fixedly connected to one end of the horizontal conveyor channel 1. Adjusting rods 18 are fixedly connected to both ends of the cross plate 17, and one end of each adjusting rod 18 is respectively slidably connected to the adjusting pull plate 15. Springs 19 are fixedly connected to one end of each adjusting rod 18, and one end of each spring 19 is fixedly connected to one end of the cross plate 17. Second threaded sleeves 21 are threadedly connected to one end of each adjusting rod 18, and first threaded sleeves 20 are threadedly connected to the middle of each adjusting rod 18. The driven roller 7 will also pull the adjusting pull plates 15 to slide on both sides of the horizontal conveyor channel 1. At this time, the sliders 16 slide on one side of the adjusting pull plates 15. The adjusting pull plates 15 can pull the adjusting rods 18 to move through the first threaded sleeves 20 and the second threaded sleeves 21. The springs 19 can be compressed through the cross plate 17 and the adjusting rods 18. Then, the self-adaptive tension adjustment can be carried out through the adjusting rods 18 and the springs 19, avoiding the breakage of the chain 8 caused by excessive tension, thereby affecting the normal operation of the device. The user can control the elasticity of the spring 19 by rotating the first threaded sleeve 20 and the second threaded sleeve 21, thereby adjusting the tension received by the chain 8, further improving the protection of the chain 8, and improving the convenience of use for the user and the safety of the device, avoiding the damage of the chain 8 caused by the inability to adjust the tension; Please refer to Figure 6 , Figure 7 and Figure 10, in this embodiment, the heat-insulating blanking mechanism includes a first closing plate 22. The upper middle part of the blanking pipe 3 is connected to the first closing plate 22 through a bearing. A limiting rod 23 is fixedly connected to the upper middle part of the blanking pipe 3. The bottom end of the blanking pipe 3 is connected to a second closing plate 24 through a rotating shaft. Travel switches 25 are symmetrically arranged at the bottom end of the blanking pipe 3, and the bottom ends of the travel switches 25 are in contact with the second closing plate 24. Both ends of the first closing plate 22 are fixedly connected with first connecting rods 26, and the directions of the first connecting rods 26 are the same as the direction of the first closing plate 22. One end of the second closing plate 24 is symmetrically and fixedly connected with second connecting rods 27, and the second connecting rods 27 are all fixedly connected to the second closing plate 24. One end of each second connecting rod 27 is connected to a third connecting rod 30 through a rotating shaft, and the top ends of the third connecting rods 30 are respectively connected to one end of the first connecting rods 26 through a rotating shaft. A counterweight 28 is slidably connected to one end of the second closing plate 24. The top end of the counterweight 28 is symmetrically slidably connected with slide rods 29, and both ends of the slide rods 29 are fixedly connected to the second closing plate 24. Electric push rods 31 are symmetrically arranged at the bottom end of the second closing plate 24, and one end of each electric push rod 31 is fixedly connected to the counterweight 28. The ash slag falls into the interior of the blanking pipe 3 through the scraping plate 9. At this time, the ash slag is at the top end of the second closing plate 24. The user controls the electric push rod 31 to work. The output end of the electric push rod 31 pushes the counterweight 28 to slide at one end of the second closing plate 24. By changing the position of the counterweight 28, the weight of the automatic blanking of this device can be controlled, that is, the collection amount of the ash slag at the top end of the second closing plate 24. When the gravity of the ash slag exceeds the set weight, at this time, one end of the second closing plate 24 makes a circular motion downward. At this time, the electric push rod 31 is controlled by the travel switch 25 to shorten, so that the counterweight 28 approaches the connection position of the blanking pipe 3 and the second closing plate 24. At this time, the ash slag at the top end of the second closing plate 24 will pour out of the blanking pipe 3. At the same time, the second closing plate 24 can make one end of the third connecting rod 30 make a circular motion through the second connecting rod 27. Since the length of the third connecting rod 30 is fixed and unchanged, the top end of the third connecting rod 30 will drive the bottom end of the first connecting rod 26 to make a circular motion. Therefore, the first connecting rod 26 will drive the first closing plate 22 to make a circular motion until one end of the first closing plate 22 abuts against the limiting rod 23. At this time, the first closing plate 22 and the first connecting rod 26 both rotate 90 degrees, and the second closing plate 24 also reaches the maximum opening state, so that the first closing plate 22 and the second closing plate 24 are respectively in the closed and open states, thereby avoiding heat loss inside the horizontal conveying channel 1 and the blanking pipe 3, preventing foreign cold air from entering the interior of this device when pouring the ash slag, thus avoiding the condensation of hot air from corroding this device, and further reducing the user's losses and ensuring the normal use of this device. When the pouring is completed, at this time, the electric push rod 31 drives the counterweight 28 to reset, and finally the first closing plate 22 is reset through the second connecting rod 27, the third connecting rod 30 and the first connecting rod 26. At this time, the ash slag falls on the top end of the second closing plate 24 for collection, which can prevent external cold air from entering this device.It can also reduce heat loss and facilitate the user to set the weight of automatic feeding; Please refer to Figure 2 , Figure 8 and Figure 9, in this embodiment, the auxiliary mechanism includes a rotating member 32. Both ends of the horizontal conveyor 1 are bolted with maintenance plates. One end of the driven roller 7 is fixedly connected to the rotating member 32. One end of a set of adjusting pull plates 15 is provided with a rotation sensor 33, and the rotation sensor 33 is located on one side of the rotating member 32. Sliding grooves 34 are symmetrically formed in the middle of the horizontal conveyor 1. One end of each sliding groove 34 is slidably connected with a first sliding plate 35. One end of each sliding groove 34 is slidably connected with a second sliding plate 36, and the second sliding plates 36 are respectively located on one side of the first sliding plates 35. The middle of each second sliding plate 36 is connected to a first support rod 37 through a rotating shaft. The middle of each first sliding plate 35 is connected to a second support rod 38 through a rotating shaft, and the top ends of the second support rods 38 are respectively connected to one end of the first support rod 37 through a rotating shaft. One side of each second support rod 38 is respectively close to the inner wall of the horizontal conveyor 1. One end of each first sliding plate 35 is connected to a threaded rod 39 through a bearing, and one end of each threaded rod 39 is threadedly connected to the second sliding plate 36 respectively. The bottom end of each first sliding plate 35 is fixedly connected with an elastic piece 41. Two groups of connecting rods 40 are arranged inside the horizontal conveyor 1, and both ends of the connecting rods 40 are respectively fixedly connected to the second sliding plate 36 and the first sliding plate 35. The middle of the horizontal conveyor 1 is symmetrically connected with a sealing cover 42 through bolts. When the chain 8 inside the device breaks, at this time the driven roller 7 stops rotating, and the rotating member 32 also stops rotating. The rotation sensor 33 can remind the user that the device has a fault. At the same time, the motor 6 stops working. When the user needs to repair the chain 8 and the scraping plate 9, the user removes the sealing cover 42 and the maintenance plates on both sides of the horizontal conveyor 1, then pulls out the damaged chain 8 and the scraping plate 9, and then moves the first sliding plate 35 and the second sliding plate 36 to one side of the driven roller 7. Place the new chain 8 and the scraping plate 9 on the surface of the driven roller 7 so that the chain 8 and the scraping plate 9 cooperate with the driven roller 7. Then the user rotates the threaded rod 39. Through the threaded rod 39, the two second sliding plates 36 and the first sliding plates 35 can be made to approach each other, so that the connection part of the second support rod 38 and the first support rod 37 moves upward. At the same time, under the action of the self-returning force of the elastic piece 41, it is more convenient for the connection part of the second support rod 38 and the first support rod 37 to move upward, and at the same time, the movement track of the second support rod 38 can also be limited, so that the connection part of the second support rod 38 and the first support rod 37 can only move upward. When the user rotates the threaded rod 39 so that the first sliding plate 35 and the second sliding plate 36 are in contact and the second support rod 38 is on one side of the driven roller 7, the user pushes the two first sliding plates 35 and the second sliding plates 36 to move inside the sliding groove 34, so as to drive the chain 8 and the scraping plate 9 to move through the first sliding plate 35 and the second sliding plate 36 until it moves to one side of the driving roller 5. The user makes one end of the chain 8 and the scraping plate 9 engage with the driving roller 5 by pushing the first sliding plate 35 and the second sliding plate 36. At this time, the scraping plate 9 is inside the plate groove 10 or the anti-slip teeth 12 are inside the tooth groove 11.The user rotates the threaded rod 39 to control the reset of the first support rod 37 and the second support rod 38. At the same time, the travel switch 25 is separated from the second slide plate 36. At this time, the second support rod 38 no longer abuts against the scraping plate 9. Then the user controls the output end of the motor 6 to rotate slowly. The motor 6 drives the driving roller 5 to rotate slowly. The driving roller 5 drives the chain 8 and the scraping plate 9 to move until one end of the chain 8 and the scraping plate 9 moves to the inner wall at the bottom of the horizontal conveying channel 1. The rotating driving roller 5 can make the chain 8 and the scraping plate 9 in a taut state. At the same time, because the chain 8 has a certain hardness, under the action of the chain 8 itself, one end of the chain 8 and the scraping plate 9 can slide on the inner wall at the bottom of the horizontal conveying channel 1 until it moves to one end of the driven roller 7. At this time, the user can connect the two ends of the chain 8, so that the chain 8 forms a loop. Finally, the device can be installed and restored, which is convenient for the user to repair and maintain the device; It should be noted that ash hoppers 2 are evenly connected to the top of the horizontal conveying channel 1. Inspection openings 4 are provided at both ends of the horizontal conveying channel 1, which is convenient for users to repair and observe. Plate grooves 10 are evenly formed on the surfaces of the driving roller 5 and the driven roller 7. The sizes of the scraping plates 9 respectively match the plate grooves 10. Tooth grooves 11 are evenly formed on the surface of the chain 8. Anti-slip teeth 12 are evenly fixedly connected to the surface of the driven roller 7, and the sizes of the anti-slip teeth 12 respectively match the tooth grooves 11, which is convenient for clamping and avoids the chain 8 from slipping on the surfaces of the driven roller 7 and the driving roller 5. The surfaces of the adjusting pull plates 15 respectively fit with the first threaded sleeve 20 and the second threaded sleeve 21. The adjusting rods 18 are respectively located inside the springs 19, which is convenient for tension adjustment. The control ends of the electric push rods 31 are respectively electrically connected to the external power supply through the travel switch 25, which is convenient for automatic blanking. The control end of the motor 6 is electrically connected to the external power supply through the rotation sensor 33. The middle parts of the elastic sheets 41 are respectively deformed by the extrusion of the second support rod 38. The sealing covers 42 are respectively located outside the sliding grooves 34, which improves the sealing performance of the device; The operation method of the device: Step 1: Ash scraping. After the ash residue in the ash hopper 2 enters the horizontal conveying channel 1, the motor 6 drives the driving roller 5, the driven roller 7, the chain 8 and the scraping plate 9 to rotate. The fallen ash residue is scraped away by the moving scraping plate 9 until it falls into the inner part of the blanking pipe 3; Step 2: Automatic tension adjustment. When the chain 8 and the driven roller 7 rotate, the driven roller 7 will pull the heat-insulating slide plate 14 to slide inside the heat-insulating groove 13. At the same time, the adjusting pull plate 15 slides on both sides of the horizontal conveying channel 1. The adjusting pull plate 15 can pull the adjusting rod 18 to move through the first threaded sleeve 20 and the second threaded sleeve 21. Then, the adjusting rod 18 and the spring 19 can be used for self-adaptive tension adjustment; Step 3: Automatic blanking. The ash slag falls into the interior of the blanking pipe 3 through the scraping plate 9. When the gravity of the ash slag exceeds the set weight, one end of the second closing plate 24 moves downward in a circular motion at this time. At this time, the travel switch 25 controls the shortening of the electric push rod 31, so that the counterweight 28 approaches the connection position of the blanking pipe 3 and the second closing plate 24. At this time, the ash slag at the top of the second closing plate 24 will pour out of the blanking pipe 3. At the same time, the second closing plate 24 can make the first connecting rod 26 and the first closing plate 22 rotate through the second connecting rod 27 and the third connecting rod 30 until one end of the first closing plate 22 abuts against the limiting rod 23. At this time, both the first closing plate 22 and the first connecting rod 26 rotate by ninety degrees, and the second closing plate 24 also reaches the maximum opening state, so that the first closing plate 22 and the second closing plate 24 are in the closed and open states respectively; Step 4: Fault. When the chain 8 inside the device breaks, the driven roller 7 stops rotating at this time, and the rotating part 32 also stops rotating. The rotation sensor 33 can remind the user that the device has a fault, and at the same time the motor 6 stops working; Step 5: Maintenance. The user removes the sealing cover 42 and the repair plates on both sides of the horizontal conveyor 1, then pulls out the damaged chain 8 and the scraping plate 9, and then moves the first sliding plate 35 and the second sliding plate 36 to one side of the driven roller 7. Fit the new chain 8 and the scraping plate 9 with the driven roller 7. By rotating the threaded rod 39, the two second sliding plates 36 and the first sliding plate 35 can be made to approach each other, so that the connection part of the second support rod 38 and the first support rod 37 moves upward. The user rotates the threaded rod 39 so that the first sliding plate 35 and the second sliding plate 36 are fitted, and the second support rod 38 is on one side of the driven roller 7. The user pushes the two first sliding plates 35 and the second sliding plates 36 to drive the chain 8 and the scraping plate 9 to move until they move to one side of the driving roller 5, so that one end of the chain 8 and the scraping plate 9 is engaged with the driving roller 5. At this time, the scraping plate 9 is inside the plate groove 10 or the anti-slip teeth 12 are inside the tooth groove 11. The user controls the first support rod 37 and the second support rod 38 to reset. The user drives the driving roller 5 to rotate and the chain 8 and the scraping plate 9 to move through the motor 6 until one end of the chain 8 and the scraping plate 9 moves to the inner wall at the bottom of the horizontal conveyor 1. At the same time, because the chain 8 has a certain hardness, under the action of the chain 8 itself, one end of the chain 8 and the scraping plate 9 can slide on the inner wall at the bottom of the horizontal conveyor 1 until it moves to one end of the driven roller 7. At this time, the user can connect the two ends of the chain 8, and finally reinstall and restore the device.

[0018] After the ash and slag inside the ash hopper 2 enter the horizontal conveying channel 1, the motor 6 drives the driving roller 5 to rotate. The driving roller 5 drives the driven roller 7 to rotate through the chain 8, and the chain 8 drives the scraping plate 9 to rotate. The plate groove 10, tooth groove 11 and anti-slip teeth 12 can prevent the chain 8 from slipping on the surfaces of the driving roller 5 and the driven roller 7. The fallen ash and slag are scraped away by the moving scraping plate 9 until they fall inside the blanking pipe 3. When the chain 8 and the driven roller 7 are rotating, the driven roller 7 will pull the heat insulation sliding plate 14 to slide inside the heat insulation groove 13. At the same time, the driven roller 7 will also pull the adjusting pull plate 15 to slide on both sides of the horizontal conveying channel 1. At this time, the slider 16 slides on one side of the adjusting pull plate 15. The adjusting pull plate 15 can pull the adjusting rod 18 to move through the first threaded sleeve 20 and the second threaded sleeve 21. The spring 19 can be compressed through the cross plate 17 and the adjusting rod 18, and then the self-adaptive tension adjustment can be carried out through the adjusting rod 18 and the spring 19 to prevent the chain 8 from breaking due to excessive tension, thereby affecting the normal operation of this device. The user can control the elasticity of the spring 19 by rotating the first threaded sleeve 20 and the second threaded sleeve 21, and then can adjust the tension received by the chain 8, further improving the protection of the chain 8 and the convenience of use for the user. The ash and slag fall inside the blanking pipe 3 through the scraping plate 9. At this time, the ash and slag are at the top of the second closing plate 24. The user controls the electric push rod 31 to work. The output end of the electric push rod 31 pushes the counterweight block 28 to slide at one end of the second closing plate 24. By changing the position of the counterweight block 28, the weight of the automatic blanking of this device can be controlled, that is, the collection amount of the ash and slag at the top of the second closing plate 24. When the gravity of the ash and slag exceeds the set weight, at this time, one end of the second closing plate 24 makes a circular motion downward. At this time, the electric push rod 31 is controlled by the travel switch 25 to shorten, so that the counterweight block 28 approaches the connection position of the blanking pipe 3 and the second closing plate 24. At this time, the ash and slag at the top of the second closing plate 24 will pour out of the blanking pipe 3. At the same time, the second closing plate 24 can make one end of the third connecting rod 30 make a circular motion through the second connecting rod 27. Since the length of the third connecting rod 30 is fixed and unchanged, the top end of the third connecting rod 30 will drive the bottom end of the first connecting rod 26 to make a circular motion. Therefore, the first connecting rod 26 will drive the first closing plate 22 to make a circular motion until one end of the first closing plate 22 abuts against the limiting rod 23. At this time, both the first closing plate 22 and the first connecting rod 26 rotate 90 degrees, and the second closing plate 24 also reaches the maximum opening state, so that the first closing plate 22 and the second closing plate 24 are respectively in the closed and open states, thereby avoiding the heat loss inside the horizontal conveying channel 1 and the blanking pipe 3. At the same time, the heat loss can be further reduced through the heat insulation cotton and the protection plate arranged on the surfaces of the horizontal conveying channel 1 and the blanking pipe 3, preventing the foreign cold air from entering the inside of this device when pouring the ash and slag, thereby avoiding the hot air from condensing and corroding this device, and further reducing the loss of the user and ensuring the normal use of this device. When the pouring is completed, at this time, the electric push rod 31 drives the counterweight block 28 to reset.Finally, the first closing plate 22 is reset by the second connecting rod 27, the third connecting rod 30 and the first connecting rod 26. At this time, the ash falls on the top of the second closing plate 24 for collection. When the chain 8 inside the device breaks, the driven roller 7 stops rotating at this time, and the rotating member 32 also stops rotating. The rotation sensor 33 can remind the user that the device has a fault. At the same time, the motor 6 stops working. When the user needs to repair the chain 8 and the scraping plate 9, the user removes the sealing cover 42 and the repair plates on both sides of the horizontal conveying channel 1, then pulls out the damaged chain 8 and the scraping plate 9, and then moves the first sliding plate 35 and the second sliding plate 36 to one side of the driven roller 7. Place the new chain 8 and the scraping plate 9 on the surface of the driven roller 7 so that the chain 8 and the scraping plate 9 cooperate with the driven roller 7. Then the user rotates the threaded rod 39. By the threaded rod 39, the two second sliding plates 36 and the first sliding plate 35 can be made to approach each other, so that the connection between the second support rod 38 and the first support rod 37 moves upward. At the same time, under the action of the self-returning force of the elastic piece 41, it is more convenient for the connection between the second support rod 38 and the first support rod 37 to move upward, and at the same time, it can also limit the movement track of the second support rod 38, so that the connection between the second support rod 38 and the first support rod 37 can only move upward. When the user rotates the threaded rod 39 so that the first sliding plate 35 and the second sliding plate 36 are in contact and the second support rod 38 is on one side of the driven roller 7, the user pushes the two first sliding plates 35 and the second sliding plates 36 to move inside the sliding groove 34, so as to drive the chain 8 and the scraping plate 9 to move through the first sliding plate 35 and the second sliding plate 36 until it moves to one side of the driving roller 5. The user makes one end of the chain 8 and the scraping plate 9 engage with the driving roller 5 by pushing the first sliding plate 35 and the second sliding plate 36. At this time, the scraping plate 9 is inside the plate groove 10 or the anti-slip teeth 12 are inside the tooth groove 11. The user rotates the threaded rod 39 to control the reset of the first support rod 37 and the second support rod 38. At the same time, the travel switch 25 is separated from the second sliding plate 36. At this time, the second support rod 38 no longer abuts against the scraping plate 9. Then the user controls the output end of the motor 6 to rotate slowly. The driving roller 5 is driven by the motor 6 to rotate slowly. The driving roller 5 drives the chain 8 and the scraping plate 9 to move until one end of the chain 8 and the scraping plate 9 moves to the inner wall of the bottom end of the horizontal conveying channel 1. The rotating driving roller 5 can make the chain 8 and the scraping plate 9 in a taut state. At the same time, because the chain 8 has a certain hardness, under the action of the chain 8 itself, one end of the chain 8 and the scraping plate 9 can slide on the inner wall of the bottom end of the horizontal conveying channel 1 until it moves to one end of the driven roller 7. At this time, the user can connect the two ends of the chain 8, so that the chain 8 forms a loop, and finally reinstall and restore the device. This device can not only reduce the loss of heat, but also prevent the outside cold air from entering the device, effectively avoid the condensation and corrosion of the hot air on the device, thereby improving the corrosion resistance of the device and the service life of the device, and can also prevent the ash from caking when it meets the cold.Prevent it from being blocked inside the device, affecting the conveyance of ash and slag. The device also facilitates later maintenance and replacement work, further reducing the user's work difficulty and improving the user's work efficiency.

The fallen ash is scraped away by the moving scraper plate (9) until it falls into the inside of the discharge pipe (3). Step 2: Automatically adjust the tension. When the chain (8) and the driven roller (7) rotate, the driven roller (7) pulls the insulation slide plate (14) to slide inside the insulation groove (13).
