SUMMARY

[0009] Preferably, the outer surface of the discharge bin is fixedly connected with a support frame, and the support frame is connected with the main cylinder; the first driving device comprises a lifting rod, a connecting rope and a first driving member, the lifting rod is fixedly connected above the first gate, and the first driving member is arranged on one side of the main cylinder; one end of the connecting rope is fixedly connected with the upper end of the lifting rod, the support frame is connected with a movable pulley, the connecting rope is slidably connected with the movable pulley, and the other end of the connecting rope is connected with the first driving member.

[0010] By adopting the technical scheme, when the main cylinder and the combustion chamber need to be communicated, first, the first driving member is started to drive the connecting rope to move downwards, under the action of the movable pulley, the first gate will move upwards, so that the main cylinder and the combustion chamber are communicated; when the main cylinder and the combustion chamber need to be cut off, the first driving member is started to drive the connecting rope to move downwards, under the action of the gravity of the first gate itself, the first gate will move downwards, so that the main cylinder and the combustion chamber are cut off, which greatly improves the convenience and speed of operation.

[0011] Preferably, the second driving device comprises a boost plate and a second driving member, the boost plate is coaxial with the main cylinder and is matched with the main cylinder; the second driving member is arranged at one end of the boost plate away from the first gate and is connected with the boost plate.

[0012] By adopting the technical scheme, when the solid waste is put into the combustion chamber, the second driving member is started to drive the boost plate to move towards the direction of the combustion chamber, so that the solid waste is put in.

[0013] Preferably, the outer circumferential surface of the boost plate is connected with a plurality of rolling wheels, and the rolling wheels are in rolling friction with the inner wall of the main cylinder.

[0014] By adopting the above technical solution, the rolling wheel makes the booster plate and the inner wall of the main cylinder roll together, which reduces the friction generated when the booster plate slides along the inner wall of the main cylinder and improves the sliding efficiency.

[0015] Preferably, the feeding hopper includes a movable sealing plate and multiple fixed sealing plates, wherein the movable sealing plate is slidably connected to two adjacent fixed sealing plates.

[0016] By adopting the above technical solution, after solid waste is put into the feeding hopper, the movable sealing plate moves towards the fixed sealing plate opposite to the movable sealing plate, thereby compacting the solid waste.

[0023] Preferably, the main cylinder has a double-layer structure, with a support plate and a reinforcing rib plate between the two layers; multiple reinforcing rods are fixedly connected between the feeding hopper and the main cylinder.

[0024] By adopting the above technical solution, the double-layer structure improves the connection strength of the main cylinder; the setting of the reinforcing rod not only provides support for the feeding hopper, but also improves the strength of the feeding device itself to withstand the load.

[0026] By adopting the above technical solution, the inner diameter of the front part gradually increases from the direction of approaching to the direction of moving away from the rear part. This design makes it easier for solid waste to fall into the combustion chamber by its own gravity, thus improving the feeding efficiency. The water circulation chamber is set up to facilitate the cooling treatment of the front part, thereby reducing the wear of the main cylinder and extending the service life of the main cylinder.

[0027] In summary, this application has the following technical effects:

[0028] 1. The design of the feeding device, which combines a double-lock air valve with a feeding device, allows solid waste to be pushed into the combustion chamber in a closed environment. This effectively solves the problem of a large amount of ash returning to the top after solid waste is added, reduces the possibility of hot air short circuit in the combustion chamber and positive pressure in the combustion chamber system, and thus reduces safety hazards.

[0029] 2. After solid waste is fed into the feeding hopper, the movable sealing plate moves towards the fixed sealing plate opposite to the movable sealing plate, thereby compacting the solid waste. This design not only allows more solid waste to be contained in the combustion chamber at one time, thereby improving processing efficiency, but also reduces the possibility of ash and dust rising.

[0030] 3. After the solid waste is compacted by the movable sealing plate, the fifth drive unit is activated to move the pressure plate downward, thereby further compacting the solid waste. This design not only makes it easier to hold more solid waste in the combustion chamber at one time, thereby improving the processing efficiency, but also further reduces the possibility of ash and dust rising.

[0036] The present application will be further described in detail below with reference to the accompanying drawings.

[0037] Reference Figure 1 , Figure 2 and Figure 3This application provides a feeding device combining a dual-channel airlock valve and a pusher, including a horizontally placed main cylinder 1, with a placement frame 2 fixedly connected to the lower end of the main cylinder 1, and the placement frame 2 fixedly connected to the ground; one end of the main cylinder 1 is open, and the open port is connected to the combustion chamber through a flange, and a first gate 3 is provided at the port position, which is slidably connected to the main cylinder 1; the first gate 3 is vertically arranged, and the cross-sectional size of the first gate 3 is greater than or equal to the cross-sectional size of the port of the main cylinder 1; a first driving device 4 is connected to the upper end of the first gate 3 to drive the first gate 3 to move up and down; a second driving device 5 is provided inside the main cylinder 1 to drive the solid waste inside the main cylinder 1 to move towards the combustion chamber; a discharge bin 6 is provided above the main cylinder 1, and both the upper and lower ends of the discharge bin 6 are open; a vertical discharge pipe 7 is connected to the lower end of the discharge bin 6, and the discharge pipe 7 is connected to the main cylinder 1; a sliding connection is provided at the lower port position of the discharge bin 6. A second gate 8 is dynamically connected, and the second gate 8 is horizontally positioned. The cross-sectional size of the second gate 8 is greater than or equal to the cross-sectional size of the lower end of the discharge hopper 6. A support base 11 is provided below the second gate 8, and the second gate 8 and the support base 11 are slidably connected. Multiple vertical reinforcing rods 12 are provided around the discharge channel. One end of the reinforcing rod 12 is fixedly connected to the lower end face of the support base 11, and the other end of the reinforcing rod 12 is fixedly connected to the main cylinder 1. A vertical connecting plate 9 is fixedly connected to one side of the second gate 8. A third driving component 10 is provided on the side of the connecting plate 9 away from the second gate 8, which drives the second gate 8 to slide left and right. The third driving component 10 can be a hydraulic cylinder. The hydraulic cylinder is horizontally positioned, and the free end of the piston rod in the hydraulic cylinder is fixedly connected to the side of the connecting plate 9. The cylinder body of the hydraulic cylinder is fixedly connected to the support base 11, and an auxiliary support frame 13 is fixedly connected between the hydraulic cylinder and the main cylinder 1.

[0038] When processing solid waste, the first drive device 4 first lowers the first gate 3 until the combustion chamber is isolated from the main cylinder 1. Then, the third drive device 10 moves the second gate 8 away from the discharge bin 6 until the discharge bin 6 is connected to the discharge channel. Next, the grab bucket grabs the solid waste to be processed and adds it to the discharge bin 6. Under its own gravity, the solid waste enters the main cylinder 1 through the discharge bin 6 and the discharge channel. Then, the third drive device 10 moves the second gate 8 closer to the discharge bin 6 until the discharge bin 6 is isolated from the discharge channel. The first drive device 4 then moves the first gate 3 upward until the combustion chamber is connected to the main cylinder 1. Finally, the second drive device 5 moves the solid waste into the combustion chamber. This design allows solid waste to be pushed into the combustion chamber in a closed environment, effectively solving the problem of large amounts of ash returning after solid waste is added, reducing the possibility of hot air short-circuiting in the combustion chamber and positive pressure in the combustion chamber system, thereby reducing safety hazards.

[0039] Reference Figure 3 In order to reduce the friction of the second gate plate 8 sliding on the support base 11, a plurality of evenly arranged first pulleys 14 are fixedly connected to the end face of the second gate plate 8 near the support base 11. There are two first pulleys 14, which are symmetrically arranged along the center line of the second gate plate 8. The end face of the support base 11 near the second gate plate 8 is provided with two sliding grooves for the first pulleys 14 to slide. The two sliding grooves are symmetrically arranged along the center line of the support base 11.

[0040] Reference Figure 1 To improve the connection strength of the main cylinder 1, the main cylinder 1 is designed with a double-layer structure, and a support plate and reinforcing ribs are provided between the two layers. To facilitate the entry of solid waste into the combustion chamber, the main cylinder 1 includes an open front part 110 and a rear part 120, wherein the rear part 120 is cylindrical, and the inner diameter of the front part 110 gradually increases from the direction closer to the rear part 120, and the upper end of the front part 110 is flush with the upper end of the rear part 120. The cross-section of the front part 110 is circular. This design allows solid waste to fall into the combustion chamber by its own gravity at the port of the main cylinder 1. Inside the combustion chamber, the possibility of solid waste remaining in the main cylinder 1 is reduced, and the feeding efficiency is improved. In order to cool down the front part 110, a water circulation chamber 15 is connected above the front part 110. The water circulation chamber 15 is hollow inside, and two opposite sides are connected to a water inlet pipe 151 and a drain pipe 152, respectively. Since the front part 110 is connected to the combustion chamber through a flange, the temperature of the front part 110 will be very high. At this time, the water circulation chamber 15 can effectively cool down the front part 110, thereby reducing the wear of the main cylinder 1 and extending the service life of the main cylinder 1.

[0041] Reference Figure 1 and Figure 2 The first driving device 4 includes a lifting rod 41, a connecting rope 42, and a first driving component 43. The lifting rod 41 is vertically fixed to the upper end face of the first gate plate 3. A support frame 16 is fixedly connected above the circulating water chamber. The support frame 16 is fixedly connected to the discharge bin 6. Multiple movable pulleys 161 are connected to the support frame 16. One end of the connecting rope 42 is fixedly connected to the upper end of the lifting rod 41. The connecting rope 42 passes through the movable pulleys 161 and is slidably connected to the movable pulleys 161. The other end of the connecting rope 42 is connected to the first driving component 43. The first driving component 43 is vertically arranged on one side of the main cylinder 1. The first driving component 43 can be a hydraulic cylinder. An ear plate is fixedly connected to the side of the main cylinder 1. The ear plate is fixedly connected to the cylinder body of the hydraulic cylinder. The free end of the piston rod in the hydraulic cylinder is fixedly connected to the connecting rope 42.

[0042] When the combustion chamber and the main cylinder 1 need to be connected, the first driving component 43 is activated to move the piston rod downward, thereby driving the connecting rope 42 downward, and then driving the first gate 3 upward until the combustion chamber and the main cylinder 1 are connected; when the combustion chamber and the main cylinder 1 need to be separated, the hydraulic cylinder is activated to move the piston rod upward, and under the action of the first gate 3's own weight, the first gate 3 will move downward until the combustion chamber and the main cylinder 1 are separated; the first driving device 4 is set to facilitate the lifting and lowering of the first gate 3, thereby facilitating the connection and separation of the combustion chamber and the main cylinder 1; the movable pulley 161 is set to reduce the wear of the connecting rope 42 and extend the service life of the connecting rope 42.

[0043] Reference Figure 2 The second driving device 5 includes a booster plate 51 and a second driving member 52. The booster plate 51 is coaxial with the rear part 120 and is adapted to the inner wall of the main cylinder 1. The second driving member 52 is located at the end of the booster plate 51 away from the first gate 3. The second driving member 52 can be a hydraulic cylinder. The free end of the piston rod in the hydraulic cylinder is fixedly connected to the booster plate 51.

[0044] When solid waste needs to be added to the combustion chamber, the second drive unit 52 is activated to move the piston rod toward the direction of the combustion chamber, thereby driving the push plate to move toward the direction of the combustion chamber, thus realizing the addition of solid waste; the setting of the second drive unit 5 facilitates the addition of solid waste.

[0045] Reference Figure 2 In order to reduce friction, improve operating efficiency and extend service life, multiple placement seats 17 are uniformly fixedly connected to the outer circumferential surface of the booster plate 51. There are five placement seats 17. Rolling wheels 18 are ball-hinged inside the placement seats 17. The rolling wheels 18 and the inner wall of the main cylinder 1 are subject to rolling friction.

[0046] Reference Figure 1 and Figure 3To facilitate the compaction of solid waste, the discharge hopper 6 includes a movable sealing plate 61 and multiple fixed sealing plates 62. Three fixed sealing plates 62 are fixedly connected to the support base 11 and are inclined downwards along the direction from the centerline of the discharge pipe 7 towards the centerline. The movable sealing plate 61 is vertically positioned and slidably connected to two adjacent fixed sealing plates 62. A vertical movable plate 19 is fixedly connected to the side of the movable sealing plate 61 away from the fixed sealing plates 62. The length of the movable plate 19 is greater than that of the movable sealing plate 61. The maximum length of plate 61, and two fixed sealing plates 62 adjacent to the movable sealing plate 61 are each provided with a fourth driving member 20 to drive the movable plate 19 to slide. Both fourth driving members 20 are connected to the movable plate 19. Both fixed sealing plates 62 adjacent to the movable sealing plate 61 are provided with a sliding groove for the movable plate 19 to slide. The fourth driving member 20 can be a hydraulic cylinder, wherein the hydraulic cylinder is horizontally arranged on the outer side of the fixed sealing plate 62, the cylinder body of the hydraulic cylinder is fixedly connected to the outer side of the fixed sealing plate 62, and the free end of the piston rod in the hydraulic cylinder is fixedly connected to the movable plate 19.

[0047] After solid waste is fed into the feeding hopper 6, the fourth drive unit 20 is activated to move the moving plate 19 toward the fixed sealing plate 62 opposite to the movable sealing plate 61. Since the moving plate 19 is fixedly connected to the movable sealing plate 61, the movable sealing plate 61 will also move accordingly, thereby compacting the solid waste. This design not only allows more solid waste to be contained in the combustion chamber at one time, thereby improving processing efficiency, but also reduces the possibility of ash and dust rising. The three fixed sealing plates 62 are inclined downward along the direction from away from to near the center line of the discharge pipe 7. This design not only makes it easy for the solid waste to fall into the main cylinder 1 by its own weight, but also facilitates further compaction of the solid waste.

[0048] Reference Figure 2 and Figure 3 To reduce the friction of the movable plate 19 sliding on the fixed sealing plate 62, a second pulley 21 is fixedly connected to each position where the movable plate 19 abuts against the fixed sealing plate 62. The axis of the second pulley 21 is perpendicular to the extension direction of the fixed sealing plate 62. Four second pulleys 21 are provided, and the fixed sealing plate 62 is provided with a sliding groove for the second pulleys 21 to slide. This design not only reduces the friction generated by the movable plate 19 sliding on the fixed sealing plate 62, but also greatly improves the sliding efficiency of the movable plate 19 sliding on the fixed sealing plate 62.

[0049] Reference Figure 1 and Figure 4In order to further compact the solid waste, a horizontal pressure plate 22 is installed in the feeding hopper 6. The upper end of the pressure plate 22 is connected to a fifth driving component 23. The fifth driving component 23 can be a hydraulic cylinder. The hydraulic cylinder is set vertically, and the free end of the piston rod in the hydraulic cylinder is fixedly connected to the end face of the pressure plate 22. A connecting frame is provided between the hydraulic cylinder and the movable sealing plate 61. The connecting frame is fixedly connected to the cylinder body of the hydraulic cylinder and the movable sealing plate 61.

[0050] After solid waste is fed into the feeding hopper 6, the movable sealing plate 61 compacts it, and then the fifth driving component 23 is activated to move the pressure plate 22 downward, thereby further compacting the solid waste. This design not only makes it easier to hold more solid waste in the combustion chamber at one time, thereby improving the processing efficiency, but also further reduces the possibility of ash and dust rising.

[0051] In summary, the usage process of this application is as follows: When processing solid waste, firstly, the first drive unit 43 is activated to drive the first gate plate 3 downwards until the combustion chamber and the main cylinder 1 are separated. Secondly, solid waste is fed into the lower hopper 6, and the fourth drive unit 20 is activated to drive the movable sealing plate 61 towards the fixed sealing plate 62 opposite to the movable sealing plate 61, thereby achieving compaction of the solid waste. Then, the fifth drive unit 23 is activated to drive the pressure plate 22 downwards, thereby further compacting the solid waste. Next, the third drive unit 10 is activated to drive... The second gate 8 moves away from the discharge bin 6 until the discharge bin 6 is connected to the discharge channel. At this time, the compressed solid waste falls into the main cylinder 1 by its own gravity. Finally, the third drive unit 10 is activated to drive the second gate 8 to move closer to the discharge bin 6 until the discharge bin 6 is separated from the discharge channel. The first drive unit 43 is activated to drive the first gate 3 to move upward until the combustion chamber is connected to the main cylinder 1. At the same time, the second drive unit 52 is activated to drive the push plate to move closer to the combustion chamber, thereby realizing the discharge of solid waste.

[0052] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
