Description

Technical Field

[0001] This utility model relates to the field of biomass fuel processing technology, and in particular to a raw material crushing device for biomass fuel processing. Background Technology

[0002] In the process of biomass fuel processing, crushing devices are widely used to crush raw materials. Biomass fuel refers to the combustion of biomass materials as fuel, which is mainly agricultural and forestry waste. It is mainly different from fossil fuels. Direct combustion of biomass is a high-pollution fuel and is not allowed in cities. Crushing devices are also used in the process of biomass fuel processing.

[0003] Existing crushing devices involve feeding raw materials into a crushing drum, crushing them with crushing blades, and then filtering and collecting the crushed materials using a filter screen, thus achieving the crushing process.

[0004] However, existing crushing devices rely on filters to purify the crushed raw materials, which cannot perform secondary crushing on larger materials, resulting in incomplete crushing and poor performance. To address these issues, a raw material crushing device for biomass fuel processing is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a raw material crushing device for biomass fuel processing, which solves the problem in the prior art that using a filter screen to filter the crushed raw material makes it impossible to further crush larger raw materials, resulting in incomplete crushing and poor performance.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a raw material crushing device for biomass fuel processing, comprising a base plate, two fixed boxes fixedly connected to one side of the top of the base plate, a second motor fixedly connected to one side of the outer wall of the front fixed box, a rotating shaft passing through and fixedly connected to the output end of the second motor, two sprockets fixedly connected to the outer ring of the rotating shaft, sprockets rotatably connected to one side of the inner wall of each of the two fixed boxes, a chain arranged between two adjacent sprockets, U-shaped plates evenly distributed fixedly connected to one side of the two chains, a movable box fixedly connected to the bottom of two adjacent U-shaped plates, a second support rod fixedly connected between the inner walls of two adjacent U-shaped plates, a second spring sleeved on the outer ring of each of two adjacent second support rods, a square plate passing through and slidably connected to one side of the outer ring of each of two adjacent second support rods, a triangular plate fixedly connected to one side of the outer ring of each of two adjacent square plates, a push plate fixedly connected between two adjacent triangular plates, a crushing box fixedly connected to the top of the base plate, and a dust removal assembly provided at the bottom of the crushing box.

[0007] By adopting the above technical solution, when it is necessary to crush the raw materials, the second motor is started. When the moving box moves to the discharge port, the larger raw materials enter the moving box. When the moving box moves to the top of the crushing box, the pusher pushes the larger raw materials back into the crushing box, and the unqualified raw materials are crushed a second time.

[0008] As a further description of the above technical solution: the dust removal component includes a telescopic tube, which passes through and is fixedly connected to the crushing box.

A conveying pipe is fixedly connected to the top of the outer wall of the square box. A rigid pipe is fixedly connected to one end of the conveying pipe. A uniformly distributed dust suction pipe is fixedly connected to the bottom of the outer ring of the rigid pipe.

[0009] By adopting the above technical solution, when dust needs to be absorbed, the dust floats on the top of the inner wall of the dust collector. The fan is turned on, and the dust can be absorbed by the suction pipe. The dust enters the drawer for collection, reducing environmental pollution.

[0010] As a further description of the above technical solution: two L-shaped plates are fixedly connected to the front side of the outer wall of the crushing box, and a first motor is fixedly connected to the front side of the outer wall of one of the L-shaped plates. A gear is passed through and fixedly connected to the output end of the first motor, and a gear is rotatably connected to the front side of the outer wall of the crushing box.

[0011] By adopting the above technical solution, the first motor can drive the gear to rotate, and the L-shaped plate can limit the gear.

[0012] As a further description of the above technical solution: the two gears are meshed together, and each of the two gears has a crushing roller fixedly connected to it through the crushing box on one side.

[0013] By adopting the above technical solution, the two gears can rotate synchronously, and the gears drive the crushing roller to crush the biomass raw materials.

[0014] As a further description of the above technical solution: both the front and rear sides of the inner wall of the crushing box are fixedly connected to a fixing plate, and a first support rod is slidably connected through the top of the fixing plate, and a first spring is sleeved on the outer ring of the first support rod.

[0018] As a further description of the above technical solution: a push plate is slidably connected to the inner wall of the mobile box.

[0019] By adopting the above technical solution, the mobile box can limit the push plate.

[0020] As a further description of the above technical solution: a cylinder is fixedly connected to one side of the bottom of the outer wall of the crushing box, and a dust suction hood is fixedly connected to the output end of the cylinder.

[0021] By adopting the above technical solution, the cylinder can drive the dust collection hood to move, which can adapt to the height of different collection bags.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] 1. This utility model provides a raw material crushing device for biomass fuel processing. First, a second motor is started via a triangular plate, a moving box, a chain, and a pusher plate. When the U-shaped plate moves the triangular plate to one side of the outer wall of the crushing box, the triangular plate moves the square plate, compressing the second spring. When the moving box moves to the discharge port, larger raw materials enter the moving box. When the moving box moves to the top of the crushing box, the second spring rebounds, and the triangular plate drives the pusher plate to push the larger raw materials back into the crushing box. This allows for secondary crushing of unqualified raw materials, improving the crushing effect.

[0024] 2. This utility model provides a raw material crushing device for biomass fuel processing. Through a telescopic pipe, a feeding hopper, a dust suction pipe, and a second filter plate, when the crushed raw material needs to be fed, a cylinder is activated to move the feeding hopper and the dust suction hood. The feeding hopper can enter the collection bag. When the raw material enters the collection bag, the dust floats on the top of the inner wall of the dust collection hood. Simultaneously, a fan is activated, and the dust suction pipe absorbs the dust inside the dust collection hood. The dust enters the drawer for collection through a rigid pipe and a conveying pipe, preventing the dust from floating in the air and reducing environmental pollution. Attached Figure Description

[0038] Working Principle: When using the crushing device, the raw material is fed into the crushing box 5. The first motor 7 is started, driving the gear 6 and the crushing roller 10 to rotate. The crushing roller 10 can crush the raw material. After the raw material is crushed, it falls on the top of the first filter plate 12. The vibration motor 13 is started, driving the first filter plate 12 to shake. When the first filter plate 12 moves downward, it can drive the first support rod 15 to move, thereby compressing the first spring 14. When the first spring 14 rebounds, the first filter plate 12 returns to its original position, increasing the shaking of the first filter plate 12. Qualified raw materials fall onto the first filter plate 12, while larger raw materials remain on the top of the first filter plate 12. Then, they enter the moving box 4 from the discharge port on one side of the crushing box 5. At the same time, the second motor 22 is started, driving the sprocket 23 to rotate. The sprocket 23 can drive multiple U-shaped plates 25 to move synchronously. When the U-shaped plates 25 drive the triangular plate 2 to move to one side of the outer wall of the crushing box 5, the triangular plate 2 drives the square plate 2 to move. The moving plate 9 compresses the second spring 28. When the moving box 4 moves to the discharge port, it stops moving. Larger raw material particles enter the moving box 4. When the moving box 4 moves to the top of the crushing box 5, the crushing box 5 releases the limit on the triangular plate 2. The second spring 28 rebounds, driving the push plate 26 and the triangular plate 2 to reset. The push plate 26 pushes the raw material back into the crushing box 5, which can crush larger raw materials a second time and improve the crushing effect. When it is necessary to discharge the crushed raw material, the starter 35 drives the discharge hopper 19 and the dust hood 18 to move. The discharge hopper 19 can enter the collection bag. When the raw material enters the collection bag, the dust floats on the top of the inner wall of the dust hood 18. At the same time, the fan 32 is started, and the dust suction pipe 30 can absorb the dust in the dust suction hood 18. The dust enters the drawer 31 through the rigid pipe 34 and the conveying pipe 20 for collection, preventing the dust from floating in the air and reducing environmental pollution.
