Description

Technical Field

[0001] The invention relates to the technical field of fuel particle preparation, in particular to a device for preparing fuel particles from combustible solid waste. Background Technology

[0002] Solid wastes rich in organic matter, such as agricultural and forestry waste and sludge, have a certain calorific value and can be harmlessly treated by incineration. However, some types of solid waste have low calorific value and are prone to producing odorous gases and dust when stored for a long time, making direct combustion inconvenient. Therefore, we propose to blend and dry different types of solid waste to produce biomass fuel pellets.

[0003] Existing vertical ring die pellet mills use top feeding. Material is added directly from the top via a conveyor and accumulates on the extrusion rollers and ring die. As the extrusion rollers rotate, the material gradually enters the space between them. Then, the material is squeezed out of the ring die by the extrusion rollers to form pellets. However, during the extrusion process, the stickiness of impurities such as sludge causes the pellets to stick to the outlet or to the material before and after the extrusion, affecting the flow of the material. Furthermore, after the material falls, the pellets accumulate in one place to form a pile, affecting the storage of the material. The piled-up material is more prone to sticking, which affects its use. Summary of the Invention

The conveyor box is rotatably connected, with connecting plates fixedly connected to the front ends of both sides. Guide plates are fixedly connected to one side of each of the two connecting plates. Sloping grooves are formed at both the upper and lower ends of each of the two guide plates. Fixed plates are slidably connected to the upper and lower ends of both sides of the front end of the conveyor box. Cutting blades are fixedly connected between each pair of the four fixed plates. Both cutting blades are in contact with the front side of the extrusion plate. Guide rods are fixedly connected to one end of each of the four fixed plates. The four guide rods pass through the four sloping grooves and are slidably connected to them. Two connecting plates on the same side form a group. Guide rails are fixedly connected between each group of connecting plates. The four guide rods pass through two guide rails and are slidably connected to them. Connecting blocks are fixedly connected to one end of each of the four guide rods. The four connecting blocks are respectively located on both sides of the two guide rails.

[0006] Preferably, a second reciprocating screw is rotatably connected to the opposite side of the outer wall of each of the two fixed sleeves. A movable plate is threadedly connected to the outer side of each of the two second reciprocating screws. A sliding groove is provided on the outer side of each of the two fixed sleeves. The two movable plates are slidably connected to the two sliding grooves to limit the movement of the movable plates and maintain stability during movement. The two movable plates are fixedly connected to two guide plates respectively. The movement of the movable plates is driven by the rotation of the second reciprocating screws, and the movable plates drive the guide plates to move.

[0007] Preferably, both sides of the inner sides of the two rotating sleeves are integrally formed with limit plates, and both sides of the two first reciprocating screws are provided with limit grooves. The two limit plates are slidably connected to the two limit grooves and are adapted to the two limit grooves.

[0008] Preferably, a limiting sleeve is fixedly connected inside the front end of each of the two fixed sleeves, and the two first reciprocating screws pass through the two limiting sleeves and are threadedly connected to the two limiting sleeves respectively. The limiting sleeves limit the first reciprocating screws, thereby allowing the first reciprocating screws to move horizontally during rotation.

[0009] Preferably, each of the two fixed sleeves has a rotating ring rotatably connected to its front end. The rotating ring is sleeved on the outside of the first reciprocating screw and slidably connected to the first reciprocating screw. Both sides of the interior of the two rotating rings are integrally formed with limit blocks. The two limit blocks are slidably connected to the interior of the two limit grooves and are adapted to the two limit grooves. The outer sides of the two rotating rings and one end of the two second reciprocating screws are fixedly connected with transmission gears. The four transmission gears are meshed with each other in pairs. Through the transmission gears, the first reciprocating screw rotates and drives the second reciprocating screw to rotate.

[0010] Preferably, a rotating rod is rotatably connected to the inside of the push plate. A bevel gear is fixedly connected to one end of the rotating rod and the outer side of the first reciprocating screw near this end. The two bevel gears are meshed together. A plurality of eccentric wheels are fixedly connected to the outer side of the rotating rod. A plurality of sliding rods are provided inside the push plate. The sliding rods penetrate the bottom wall of the push plate and are slidably connected to the push plate. An upper pressure plate is fixedly connected to the top of each sliding rod. The eccentric wheels are respectively in contact with the upper pressure plates. When the rotating rod rotates, it drives the eccentric wheels to rotate, thereby pushing the upper pressure plates to move up and down.

[0011] Preferably, a support plate is fixedly connected to the outer side of each of the slide rods, and a return spring is sleeved on the outer side of each of the slide rods. The two ends of the return spring are fixedly connected to the support plate and the push plate respectively, so as to limit the position of the support plate.

[0012] Preferably, a pad is fixedly connected to the bottom of the push plate, a receiving box is fixedly connected to the bottom of the pad, a plurality of support blocks are fixedly connected to the front bottom of the receiving box, a hinge rod is hinged inside each of the support blocks, and a top rod is fixedly connected to the front end of each of the hinge rods.

[0013] Preferably, each of the sliding rods has a lower pressure plate fixedly connected to its bottom end, and the lower pressure plates are respectively in contact with the top rods. The bottom of the receiving box is fixedly connected to the support plates, and the hinge rods are respectively disposed inside the support plates. The receiving box is slidably connected to the bottom of the conveying box, and the raw materials are collected by the receiving box moving with the push plate.

[0014] Preferably, a geared motor is fixedly connected to the top of the mixing box, the output end of the geared motor is fixedly connected to two mixing blades, and a feed pipe is fixedly connected to the rear side of the mixing box.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. This application enables the limiting groove to move horizontally during rotation. This horizontal movement of the limiting groove drives the push plate, which in turn moves the pad and receiving box, causing the receiving box to reciprocate and receive material particles. This ensures the material is evenly distributed inside the receiving box, with the particles layered for easy storage. Furthermore, the horizontal movement of the receiving box ensures uniform distribution of the material particles, guaranteeing even filling within the box and improving the quality and consistency of the fuel particles. This increases production efficiency, reduces manual intervention, and enables automated production.

[0016] 2. This application enables the guide plate to limit the guide rods via inclined grooves on its upper and lower sides during horizontal movement. This limits the guide rods along the inclined grooves, allowing them to move relative to each other within the guide rail. The two guide rods then drive the two connecting blocks to move relative to each other, which in turn drives the two fixed plates to move relative to each other. These fixed plates then drive the cutting blades to move relative to each other, resulting in a cyclical relative movement of the two cutting blades that cuts the material extruded from the extrusion plate, forming material particles. This achieves a continuous material granulation process, preventing material adhesion and facilitating discharge. During this process, the size and shape of the material particles can be controlled by adjusting the rotational speed of the first reciprocating screw and the helical blades to meet different production needs.

[0017] 3. This application uses several eccentric wheels to alternately push several upper pressure plates downwards, causing the upper pressure plates to drive several sliding rods to slide up and down. As the sliding rods move, they compress several return springs, which in turn cause the sliding rods to drive several lower pressure plates downwards. These lower pressure plates then push several top rods downwards, causing the top rods to push several hinged rods to deflect. The rear ends of these hinged rods then strike the bottom of the material box, horizontally spreading the particles. This method ensures uniform particle distribution during spreading and prevents material accumulation. With the continuous movement of the conveyor belt, the material particles are transported to the next processing stage for further processing or packaging. The entire device design considers efficiency and quality control during the material granulation process, ensuring the standardization and consistency of the final product.

[0022] Two fixed sleeves 9 are rotatably connected to opposite sides of their outer outer walls by second reciprocating screws 22. Each of the two second reciprocating screws 22 is threadedly connected to a movable plate 23. Each fixed sleeve 9 has a sliding groove on its outer side, and the two movable plates 23 are slidably connected within the two grooves to limit their movement and maintain stability. The two movable plates 23 are fixedly connected to two guide plates 21. The rotation of the second reciprocating screws 22 drives the movable plates 23 to move, which in turn drives the guide plates 21 to move. Limiting plates 11 are integrally formed on both sides of the interior of each of the two rotating sleeves 10. Limiting grooves 14 are formed on both sides of each of the two first reciprocating screws 13. The two limiting plates 11... The two fixed sleeves 9 are respectively slidably connected inside the two limiting grooves 14 and adapted to the two limiting grooves 14. The rear ends of the two fixed sleeves 9 are fixedly connected to the positive and negative motors 12. The output ends of the two positive and negative motors 12 pass through the two fixed sleeves 9 and are rotatably connected to the two fixed sleeves 9. The output ends of the two positive and negative motors 12 are respectively fixedly connected to the rear ends of the two rotating sleeves 10. The rotating sleeves 10 are rotated by starting the positive and negative motors 12. The front ends of the two fixed sleeves 9 are fixedly connected to the limiting sleeves 15. The two first reciprocating screws 13 pass through the two limiting sleeves 15 and are threadedly connected to the two limiting sleeves 15. The first reciprocating screws 13 are limited by the limiting sleeves 15. The first reciprocating screws 13 move horizontally during the rotation.

[0023] Two fixed sleeves 9 are rotatably connected to the front ends of rotating rings 17. The rotating rings 17 are sleeved on the outside of the first reciprocating screw 13 and slidably connected to the first reciprocating screw 13. The two rotating rings 17 are integrally formed with limit blocks 18 on both sides inside. The two limit blocks 18 are slidably connected to the inside of the two limit grooves 14 and are adapted to the two limit grooves 14. The two rotating rings 17 and one end of the two second reciprocating screws 22 are fixedly connected with transmission gears 19. The four transmission gears 19 are meshed with each other and are transmitted through the transmission gears 19, so that the first reciprocating screw 13 rotates and drives the second reciprocating screw 22 to rotate.

[0024] A rotating rod 31 is laterally rotatably connected inside the push plate 30. A bevel gear 32 is fixedly connected to one end of the rotating rod 31 and the outer side of the first reciprocating screw 13 near this end. The two bevel gears 32 mesh with each other. Several eccentric wheels 33 are fixedly connected to the outer side of the rotating rod 31. Several sliding rods 34 are provided inside the push plate 30, each sliding rod 34 penetrating the bottom wall of the push plate 30 and slidingly connected to it. An upper pressure plate 35 is fixedly connected to the top of each sliding rod 34. The eccentric wheels 33 are respectively in contact with the upper pressure plates 35. When the rotating rod 31 rotates, it drives the eccentric wheels 33 to rotate, thereby pushing the upper pressure plates 35 to move up and down. A support plate 37 is fixedly connected to the outer side of each sliding rod 34. A return spring 36 is sleeved on the outer side of each sliding rod 34. The two ends of the 6 are fixedly connected to the support plate 37 and the push plate 30 respectively, limiting the support plate 37. The bottom of the push plate 30 is fixedly connected to the pad plate 43, and the bottom of the pad plate 43 is fixedly connected to the receiving box 44. Several support blocks 39 are fixedly connected to the bottom front side of the receiving box 44. Each of the support blocks 39 has a hinge rod 40 hinged inside. The front end of each of the hinge rods 40 is fixedly connected to the top rod 42. The bottom of each of the sliding rods 34 is fixedly connected to the lower pressure plate 38. The lower pressure plate 38 is respectively in contact with the top rod 42. Several support plates 41 are fixedly connected to the bottom of the receiving box 44. Several hinge rods 40 are respectively set inside the support plates 41. The receiving box 44 is slidably connected to the bottom of the conveying box 5. The receiving box 44 moves with the push plate 30 to collect the raw materials.

[0025] In use, the raw materials are fed into the mixing box 1 through the feed pipe 3, and the two mixing blades 6 are driven to rotate relative to each other by the geared motor 2. The two mixing blades 6 mix and extrude the raw materials, so that the raw materials are transferred from the discharge port at the bottom of the receiving hopper 4 into the conveying box 5. A power source is installed at the rear of the conveying box 5 and connected to several spiral blades 7, which drive the spiral blades 7 to rotate. The material is then transferred forward by the rotation of the spiral blades 7, so that the material is discharged from the extrusion plate 8. The material is squeezed outward from several outlets of the extrusion plate 8.

[0026] The forward and reverse motor 12 is started, which drives the rotating sleeve 10 to rotate. When the rotating sleeve 10 rotates, it drives the limiting plates 11 on both sides to limit the limiting groove 14. This causes the limiting plates 11 to drive the limiting groove 14 to rotate, which in turn causes the first reciprocating screw 13 to rotate synchronously with the rotating sleeve 10. When the first reciprocating screw 13 rotates, it is limited by the limiting sleeve 15, which in turn limits the limiting sleeve 15. This causes the limiting groove 14 to move horizontally during rotation. When the limiting groove 14 moves horizontally, it drives the push plate 30 to move. When the push plate 30 moves, it drives the pad 43 and the receiving box 44 to move, which causes the receiving box 44 to move back and forth to receive the material particles. This allows the material to be evenly spread inside the receiving box 44, and the material particles are layered for easy storage. Furthermore, the horizontal movement of the receiving box 44 enables uniform distribution of material particles, ensuring even filling within the box and thus improving the quality and consistency of the fuel particles. The entire device is designed to increase production efficiency, reduce manual intervention, and achieve automated production.

[0027] The forward and reverse motor 12 is started, causing the rotating sleeve 10 to rotate. As the rotating sleeve 10 rotates, it drives the first reciprocating screw 13 to rotate synchronously. During rotation, the first reciprocating screw 13 limits the limit block 18 via the limiting groove 14, thereby driving the limit block 18 and the rotating ring 17 to rotate. This, in turn, causes the rotating ring 17 to drive the transmission gear 19 to rotate. As the transmission gear 19 rotates, it drives the second reciprocating screw 22 to rotate, thus moving the moving plate 23. The movement of the moving plate 23 then moves the guide plate 21, causing the guide plate 21 to move. During horizontal movement, the inclined grooves 24 on both sides of the guide plate 21 limit the guide rod 27, thereby limiting the guide rod 27 along the inclined grooves 24. This allows the guide rod 27 to move relative to the guide rail 26, causing the two guide rods 27 to drive the two connecting blocks 28 to move relative to each other. This, in turn, causes the two fixed plates 25 to move relative to each other, which in turn drives the cutting blades 29 to move relative to each other. The two cutting blades 29 then perform a cyclical relative movement to cut the material extruded from the extrusion plate 8, forming material particles. This achieves a continuous material granulation process, preventing material from sticking together and facilitating discharge. During this process, the size and shape of the material particles can be controlled by adjusting the rotational speed of the first reciprocating screw 13 and the spiral blades 7 to meet different production needs.

[0028] As the first reciprocating screw 13 rotates, it drives the bevel gear 32 to rotate, which in turn drives the rotating rod 31 to rotate. The rotating rod 31 then drives several eccentric wheels 33 to rotate, which in turn alternately push several upper pressure plates 35 downwards. These upper pressure plates 35 then drive several sliding rods 34 to slide up and down. As the sliding rods 34 move, they compress several return springs 36, causing them to drive several lower pressure plates 38 downwards. These lower pressure plates 38 then push several top rods 42 downwards, which in turn push several hinged rods 40 to deflect. The rear ends of these hinged rods 40 then strike the bottom of the material box 44, horizontally spreading the particles. This method ensures uniform particle distribution during spreading and prevents material accumulation. With the continuous movement of the conveyor belt, the material particles are transported to the next processing stage for further processing or packaging. The entire device is designed with efficiency and quality control in mind during the particle granulation process, ensuring the standardization and consistency of the final product.
