Description

Technical Field

[0001] The utility model relates to the technical field of biomass particle processing, in particular to a feeding device for biomass particle production with dust prevention and suppression. Background Technique

[0002] Biomass particles are cold-compactly formed from crushed biomass straw, forestry waste and other raw materials by using a pressure roller and a ring die under normal temperature conditions. The formed particles are convenient for storage and transportation, and greatly improve the combustion performance of biomass.

[0003] For example, the Chinese utility model patent with the application number 202322551228.7 discloses a conveying device for biomass particle processing, which includes a support main body. The support main body is arranged as a rectangular hollow cavity with openings at both ends. It also includes a conveying component, a blanking component, a drying air filtration component and a collection component. The conveying component is arranged at the bottom of the support main body, the blanking component is arranged on one side of the upper part of the support frame, the collection component is arranged on one side of the support main body close to the blanking component, and the drying air filtration component is arranged on the inner upper wall of the support main body on the side far from the blanking component. This device can ensure that biomass particles evenly fall on the conveyor belt, blow warm air to dry the biomass particles during transportation while taking away the dust attached to the surface of the biomass particles and the debris generated by bumps, and is a conveying device for biomass particle processing that centrally recovers.

[0004] The above patent protects the air suction end of the second air pump through a protective net to prevent impurities from entering, but lacks a mechanism for cleaning the protective net. After long-term use, dust and impurities are easily adsorbed on the surface of the protective net, causing blockage. Moreover, since the protective net is located inside the support main body, it is also inconvenient to manually clean the protective net; and the above patent lacks a function for cleaning the impurities adsorbed on the conveyor belt. When the conveyor belt conveys biomass particles, some impurities may adhere to the conveyor belt. When it rotates below the driving roller, under the vibration force during the operation of the device, the impurities adhered to the conveyor belt fall into the working environment, causing pollution to the working environment and increasing the workload of the later staff for cleaning it.

A cleaning assembly for cleaning the L-shaped filter plate 5 is also arranged on the front of the dust collection box 3. A Y-shaped bifurcated pipe 6 is fixedly connected to the side of the dust collection box 3 away from the suction fan 4. The two ends of the Y-shaped bifurcated pipe 6 away from the dust collection box 3 are respectively fixedly connected with a suction hose 7 and a suction pipe 8. The other end of the suction pipe 8 penetrates through the frame 1 and is fixedly connected with a horizontal pipe 9. A plurality of suction ports 10 are opened on the horizontal pipe 9. The other end of the hose is fixedly connected with a suction hopper 11. A cleaning brush 12 is fixedly connected inside the suction hopper 11. A driving assembly for driving the suction hopper 11 to move left and right reciprocally is also arranged on the frame 1.

[0027] The conveying assembly includes a driving motor 13, a driving roller 14, a driven roller 15 and a conveyor belt 16. The driving motor 13 is fixedly installed on the frame 1. The driving roller 14 and the driven roller 15 are respectively rotatably installed on both sides inside the frame 1. The conveyor belt 16 is drivingly connected between the outer surfaces of the driving roller 14 and the driven roller 15. The top of the cleaning brush 12 is abutted against the outer surface of the conveyor belt 16.

[0028] The cleaning assembly includes a moving rod 17 movably penetrating and installed on the front of the dust collection box 3. One end of the moving rod 17 located inside the dust collection box 3 is fixedly connected with an L-shaped scraper 18. The L-shaped scraper 18 is adapted to and abutted against the L-shaped filter plate 5. The other end of the moving rod 17 is fixedly connected with a push-pull rod 19.

[0029] When the L-shaped filter plate 5 needs to be cleaned after being used for a period of time, the worker holds the push-pull rod 19 and pushes and pulls it back and forth, so as to drive the L-shaped scraper 18 to move back and forth through the moving rod 17, realizing the scraping of the impurities adsorbed on the L-shaped filter plate 5, avoiding the blockage of the L-shaped filter plate 5, and the operation is simple and convenient, with strong practicability.

[0030] The driving assembly includes two guide rods 20 fixedly installed at the bottom of the frame 1. Guide rings 21 are movably sleeved on the outer surfaces of the two guide rods 20. The two guide rings 21 are respectively fixedly connected to the front and back of the dust suction hopper 11. And a connecting rod 22 is hingedly installed on one of the guide rings 21. The other end of the connecting rod 22 is hinged with a crank 23. The crank 23 is fixedly connected to the end of the driving roller 14 away from the driving motor 13.

[0031] A control panel 24 is fixedly installed on the front of the frame 1. The control panel 24 is electrically connected to the driving motor 13. A cleaning door 25 is hingedly installed on the front of the dust collection box 3. The setting of the cleaning door 25 facilitates the staff to clean the impurities collected in the dust collection box 3.

[0032] Working principle: When using this feeding device to convey biomass particles, first align the upper port of the feeding cylinder 2 on this feeding device with the discharge port of the forming device, so that the biomass particles fall onto the conveyor belt 16 through the feeding cylinder 2, and start the driving motor 13 through the control panel 24. The output end of the driving motor 13 rotates to drive the driving roller 14 to rotate, thereby driving the conveyor belt 16 to move for the conveying operation of the biomass particles. Moreover, the driving roller 14 rotates to drive the crank 23 to rotate, thereby pushing the guiding ring 21 hinged and installed thereon to move reciprocally left and right along the guiding rod 20 through the connecting rod 22, and then driving the dust suction hopper 11 and the cleaning brush 12 to move synchronously. The moving cleaning brush 12 can brush off the impurities adhered to the conveyor belt 16, realizing the automatic cleaning treatment of the conveyor belt 16, improving the cleanliness of the conveyor belt 16. At the same time, start the suction fan 4 through the control panel 24.

Furthermore, there is a certain suction force at the dust suction port 10 and the dust suction hopper 11. The dust suction port 10 sucks the dust and impurities generated during the conveying process of the biomass particles in the frame 1 into the horizontal pipe 9, and conveys them to the dust collection box 3 through the dust suction pipe 8 and the Y-shaped bifurcation pipe 6 in sequence. Moreover, the dust suction hopper 11 can suck the impurities brushed off from the conveyor belt 16 and convey them to the dust collection box 3 through the dust suction hose 7 and the Y-shaped bifurcation pipe 6 in sequence for unified collection;

[0033] Through the setting of the L-shaped filter plate 5, the suction fan 4 can be protected to prevent the impurities in the dust collection box 3 from entering the suction fan 4. When the L-shaped filter plate 5 needs to be cleaned after being used for a period of time, the worker holds the push-pull rod 19 and pushes and pulls it back and forth, thereby driving the L-shaped scraper 18 to move back and forth through the moving rod 17, realizing the scraping of the impurities adsorbed on the L-shaped filter plate 5, preventing the L-shaped filter plate 5 from being blocked, and the operation is simple and convenient, with strong practicability.
