Technical Field
[0001] This invention relates to the field of grain processing equipment technology, and in particular to a device for recycling waste from grain dryers. Background Technology
[0002] The mechanization of grain drying is more important than the mechanization of field operations. Currently, dryers are mostly used for drying, and they are an important guarantee for a bumper harvest of grains. Existing grain dryer units mostly adopt a combination of combustion furnace, elevator and drying tower. The combustion furnace burns fuel to generate hot air, which is sent into the drying tower for drying.
[0003] During the hot air drying process, waste materials such as grain husks, awns, and fuzz are blown out of the grain. Currently, after collecting such waste materials with bag filters, they are not directly utilized. They are often treated as waste materials or sent to specialized recycling plants for processing, which is quite troublesome. Summary of the Invention
[0004] To address the aforementioned problems, this invention provides a device for recycling waste from a grain dryer. This device can directly utilize the heat from a combustion furnace to perform high-temperature extrusion of the collected drying waste. After being extruded into blocks, the waste is returned to the combustion furnace as new fuel blocks, thereby achieving waste recycling, reducing resource waste, and increasing energy efficiency.
[0005] To solve the above problems, the technical solution adopted by the present invention is as follows:

A mounting frame is fixedly installed on the top of the dryer combustion furnace. Two movable hoppers are mounted on the top of the mounting frame, and multiple feeding pipes are installed at the bottom of the hoppers. The top of the dryer combustion furnace has two strip-shaped sealing openings, each containing a heat-conducting plate that can move vertically and offset into the heating chamber. The heat-conducting plate contains multiple briquetting grooves corresponding to the feeding pipes. Multiple movable extrusion columns are installed at the bottom of the hoppers, staggered with the feeding pipes and adapted to the briquetting grooves. The heat-conducting plate has multiple slots for inserting the corresponding extrusion columns. Opening and closing components are installed on both sides of the bottom of the briquetting grooves. A bracket is fixedly installed on the top of the dryer combustion furnace between the two heat-conducting plates, and a pushing component that extends into the briquetting grooves is installed at the bottom of the bracket.
[0007] Preferably, the bracket has two opposing threaded rods rotatably connected inside, and each of the two threaded rods is threaded with a Z-shaped movable arm. The ends of the Z-shaped movable arms are elastically mounted with connectors, and the ends of the connectors are fixedly connected to the heat-conducting plates on the corresponding sides.
[0008] Preferably, the tops of both threaded rods are fixedly connected to meshing gears, and the top of the bracket is equipped with a first motor that can drive one of the threaded rods to rotate.
[0009] Preferably, the side wall of the connector is provided with a groove, and the end of the Z-shaped moving arm is slidably installed in the groove and elastically connected to a first spring.
[0010] Preferably, a pair of first hydraulic cylinders are fixedly installed at the bottom of the hopper, abutment plates are fixedly connected to the top of the multiple extrusion columns, and connecting plates are fixedly connected to both sides of the multiple abutment plates. The telescopic ends of the pair of first hydraulic cylinders are fixedly connected to the corresponding two abutment plates, and the two connecting plates are respectively located on both sides of the multiple feed pipes.
[0011] Preferably, two second hydraulic cylinders arranged in a front-rear direction are fixedly installed on the front side of the mounting frame, and the telescopic ends of the second hydraulic cylinders are fixedly connected to the corresponding hoppers.
[0012] Preferably, the opening and closing assembly includes openings on both sides of the bottom of the pressure block groove, the top of the opening is provided with a groove, a baffle is elastically connected to the groove by a second spring, the lower end of the baffle extends into the opening and seals the opening, the front side of the heat-conducting plate is provided with a connector electrically connected to a plurality of second springs, the front side of the mounting bracket is fixedly mounted with a horizontal plate, the horizontal plate is provided with two connectors that cooperate with the corresponding connectors, and the connectors are externally connected to a controller.
[0013] Preferably, the pushing assembly includes multiple cylinders disposed on both sides of the bottom of the support, and the telescopic ends of the multiple cylinders correspond one-to-one with multiple openings on the corresponding sides.
[0014] Preferably, a second motor is installed on the front side wall of the foremost feeding pipe, and the output end of the second motor is fixedly connected to a rotating rod that passes through the top opening of multiple feeding pipes on the rear side. Each section of the rotating rod located inside the multiple feeding pipes is fixedly connected to a baffle plate.
[0015] Preferably, multiple feeding inclined plates are fixedly connected to both sides of the top of the dryer combustion furnace, and the multiple feeding inclined plates correspond one-to-one with multiple outer openings. Both sides of the dryer combustion furnace are provided with feeding hoppers corresponding to the feeding inclined plates.
[0016] The beneficial effects of this invention are as follows:
[0017] 1. By installing two staggered, vertically movable heat-conducting plates and multiple feeding pipes, the heat-conducting plates are equipped with multiple pressing slots. When the first motor is started, a pair of gears drives two threaded rods to rotate in opposite directions. Two Z-shaped moving arms drive the two heat-conducting plates to move up and down in a staggered manner, intermittently entering the heating chamber. When using the high temperature hot pressing in the heating chamber, it can also avoid overheating and combustion caused by prolonged heating. After the heat-conducting plates complete the pressing, they can move upward and automatically connect with multiple feeding pipes. When the second motor is started, a rotating rod drives multiple baffle plates to rotate, realizing the automatic feeding process. The waste material collected in the hopper can automatically fill multiple pressing slots.
[0018] 2. By installing a first hydraulic cylinder, a second hydraulic cylinder, and multiple extrusion columns, as the heat-conducting plate rises away from the heating chamber, the multiple extrusion columns are inserted into the corresponding slots. When the heat-conducting plate moves down into the heating chamber, the second hydraulic cylinder is activated to drive the corresponding hopper forward, so that the multiple extrusion columns correspond to multiple briquetting slots. The first hydraulic cylinder is activated, and through the connecting plate and multiple abutments, the multiple extrusion columns can be driven into the briquetting slots to extrude waste material under the high temperature of the heating chamber, extruding it into blocks. The preparation process of multiple fuel blocks can be completed simultaneously.
[0019] 3. By installing the feeding assembly, opening and closing assembly, and feeding ramp, after the heat-conducting plate completes the pressing and rises out of the heating chamber, the corresponding electrical connector contacts the electrical base, and the controller turns on the power supply. The second springs of multiple opening and closing assemblies are energized and retract, pulling the baffle plate upward to open the openings on both sides of the pressing groove. At this time, multiple cylinders on the corresponding side are activated, and the extension and retraction ends of the cylinders enter the pressing groove, pushing out the fuel block at the bottom. The fuel block falls into the feeding hopper through the feeding ramp and returns to the combustion furnace for combustion, realizing waste recycling, reducing resource waste, and saving energy.

[0028] Reference Figure 1-5 A device for recycling waste from a grain dryer includes a dryer combustion furnace 1, a heating chamber 3 inside the dryer combustion furnace 1, a mounting frame 7 fixedly installed on the top of the dryer combustion furnace 1, two movable hoppers 14 on the top of the mounting frame 7, multiple feed pipes 10 installed at the bottom of the hoppers 14, two strip-shaped sealing openings 5 on the top of the dryer combustion furnace 1, and heat-conducting plates 4 that can move up and down in a staggered manner into the heating chamber 3 installed in each of the two strip-shaped sealing openings 5, with multiple feed pipes 10 installed in the heat-conducting plates 4. The briquetting groove 13 corresponds one-to-one with the multiple feeding pipes 10. The bottom of the hopper 14 is equipped with multiple extrusion columns 12 that can move up and down. The multiple extrusion columns 12 are staggered with the multiple feeding pipes 10 and adapted to the briquetting groove 13. The heat-conducting plate 4 is provided with multiple slots 33 for the corresponding extrusion columns 12 to be inserted. Opening and closing components are installed on both sides of the bottom of the briquetting groove 13. The top of the dryer combustion furnace 1 is fixedly installed with a bracket 8 between the two heat-conducting plates 4. The bottom of the bracket 8 is equipped with a pushing component that can extend into the briquetting groove 13.
[0029] Furthermore, two opposing threaded rods 29 are rotatably connected inside the bracket 8. Each threaded rod 29 is threaded with a Z-shaped moving arm 25. A connector 26 is elastically installed at the end of each Z-shaped moving arm 25. The end of the connector 26 is fixedly connected to the heat-conducting plate 4 on the corresponding side. The top of each threaded rod 29 is fixedly connected with a meshing gear 24. A first motor 23 is installed on the top of the bracket 8, which can drive one of the threaded rods 29 to rotate. When the first motor 23 is started, the two threaded rods 29 are driven to rotate in opposite directions through a pair of gears 24. The two Z-shaped moving arms 25 drive the two heat-conducting plates 4 to move up and down in a staggered manner. That is, one heat-conducting plate 4 rises and leaves the heating chamber 3, while the other heat-conducting plate 4 moves down and enters the heating chamber 3 intermittently.
[0030] Furthermore, the side wall of the connector 26 is provided with a groove 9, and the end of the Z-shaped moving arm 25 is slidably installed in the groove 9 and elastically connected to the first spring 27, so that during the extrusion process of the first hydraulic cylinder, the connector 26 directly abuts against the top of the dryer combustion furnace 1 and does not make hard contact with the Z-shaped moving arm 25.
[0031] Furthermore, a pair of first hydraulic cylinders 31 are fixedly installed at the bottom of the hopper 14, and abutment plates 30 are fixedly connected to the top of multiple extrusion columns 12. Connecting plates 11 are fixedly connected to both sides of the multiple abutment plates 30. The telescopic ends of the pair of first hydraulic cylinders 31 are fixedly connected to the corresponding two abutment plates 30. The two connecting plates 11 are located on both sides of the multiple feed pipes 10. When the first hydraulic cylinders 31 are started, the multiple extrusion columns 12 can be driven into the briquetting groove 13 through the connecting plates 11 and the multiple abutment plates 30. The waste material is extruded under the high temperature of the heating chamber 3 and extruded into blocks. The preparation process of multiple fuel blocks can be completed at one time.
[0032] Furthermore, two second hydraulic cylinders 16 arranged in a front-rear direction are fixedly installed on the front side of the mounting frame 7. The telescopic end of the second hydraulic cylinder 16 is fixedly connected to the corresponding hopper 14. When the second hydraulic cylinder 16 on the corresponding side is activated, it drives the corresponding hopper 14 to move forward, so that the multiple extrusion columns 12 correspond to the multiple pressure block grooves 13.
[0033] Specifically, the opening and closing assembly includes openings 22 on both sides of the bottom of the pressure block groove 13. The top of the opening 22 is provided with a groove 20. A baffle 21 is elastically connected to the groove 20 by a second spring 19. The lower end of the baffle 21 extends into the opening 22 and seals the opening 22. The front side of the heat-conducting plate 4 is provided with a connector electrically connected to multiple second springs 19. A horizontal plate 18 is fixedly installed on the front side of the mounting bracket 7. The horizontal plate 18 is provided with two connectors 17 that cooperate with the corresponding connectors. The connectors 17 are connected to an external controller. The corresponding connectors contact the connectors 17. Power is turned on by the controller. The second springs 19 of the multiple opening and closing assemblies are energized and contracted, pulling the baffle 21 upward to open the openings 22 on both sides of the pressure block groove 13.
[0034] Specifically, the feeding assembly includes multiple cylinders 28 set on both sides of the bottom of the support 8. The telescopic ends of the multiple cylinders 28 correspond one-to-one with multiple openings 22 on the corresponding sides. Multiple feeding ramps 6 are fixedly connected to both sides of the top of the dryer combustion furnace 1. The multiple feeding ramps 6 correspond one-to-one with multiple outer openings 22. Both sides of the dryer combustion furnace 1 are provided with feeding hoppers 2 corresponding to the feeding ramps 6. When the multiple cylinders 28 on the corresponding sides are activated, the telescopic ends of the cylinders 28 pass through the openings 22 and enter the briquetting groove 13, pushing out the fuel blocks at the bottom. The fuel blocks fall into the feeding hoppers 2 through the feeding ramps 6 and return to the combustion furnace for combustion, thus realizing the reuse of waste materials.
[0035] Furthermore, a second motor 34 is installed on the front wall of the foremost feeding pipe 10. The output end of the second motor 34 is fixedly connected to a rotating rod 32 that passes through the top opening of multiple feeding pipes 10 on the rear side. Each section of the rotating rod 32 located inside the multiple feeding pipes 10 is fixedly connected to a baffle plate 15. When the second motor 34 is started, the rotating rod 32 drives the multiple baffle plates 15 to rotate, thereby realizing the automatic feeding process.
[0036] After the waste material blown out of the dryer is collected, it enters two hoppers 14 for recycling. When recycling, simply start the first motor 23, which drives two threaded rods 29 to rotate in opposite directions through a pair of gears 24. Through two Z-shaped moving arms 25, the two heat-conducting plates 4 move up and down in a staggered manner. That is, one heat-conducting plate 4 rises and leaves the heating chamber 3, while the other heat-conducting plate 4 moves down and enters the heating chamber 3. It enters the heating chamber 3 intermittently. When using the high temperature hot pressing in the heating chamber, it can also avoid overheating and combustion caused by prolonged heating. The rising heat-conducting plate 4 can automatically connect with multiple feeding pipes 10. Multiple feeding pipes 10 are inserted into multiple pressing slots 13. Start the second motor 34, which drives multiple baffle plates 15 to rotate through the rotating rod 32 to realize the automatic feeding process. The waste material collected in the hopper automatically fills multiple pressing slots 13.
[0037] As the heat-conducting plate 4 rises away from the heating chamber 3, multiple extrusion columns 12 are inserted into the corresponding slots 33. When the heat-conducting plate 4 moves down into the heating chamber 3, the lower end of the extrusion column 12 is higher than the top of the heat-conducting plate 4. The second hydraulic cylinder 16 on the corresponding side is activated to drive the corresponding hopper 14 forward, so that the multiple extrusion columns 12 correspond to multiple briquetting slots 13. The first hydraulic cylinder 31 is activated, and through the connecting plate 11 and multiple abutment plates 30, the multiple extrusion columns 12 can be driven into the briquetting slots 13 to extrude waste material under the high temperature of the heating chamber 3 and extrude it into blocks. The preparation process of multiple fuel blocks can be completed at one time.
[0038] After the heat-conducting plate 4 completes the pressing and rises out of the heating chamber 3, the corresponding electrical connector contacts the electrical base 17, and the power supply is turned on by the controller. The second spring 19 of the multiple opening and closing components is energized and retracts, pulling the baffle 21 to move upward and open the openings 22 on both sides of the pressing groove 13. At this time, the multiple cylinders 28 on the corresponding side are activated. The telescopic end of the cylinder 28 passes through the opening 22 and enters the pressing groove 13, pushing out the fuel block (waste block) at the bottom. It falls into the feeding hopper 2 through the feeding inclined plate 6 and returns to the combustion furnace for combustion, realizing the reuse of waste, reducing resource waste, and making it more energy-efficient.
[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
