Description

Technical Field

[0001] The utility model belongs to the technical field of biomass fuel processing, in particular to a raw material crushing device for biomass fuel. Background Art

[0002] Biomass fuel refers to the burning of biomass materials as fuel, which is generally mainly agricultural and forestry waste. It is mainly different from fossil fuels. Under the current national policies and environmental protection standards, direct combustion of biomass is a high-pollution fuel and is only used in large stoves in rural areas. It is not allowed to be used in cities. The application of biomass fuel is actually mainly biomass molded fuel, which uses agricultural and forestry waste as raw materials, and is made into various molded forms through processes such as crushing, mixing, extrusion, and drying. It is a new type of clean fuel that can be directly burned.

[0003] First of all, the existing biomass fuel needs to be initially crushed during the processing process. Since there are a large number of dust particles remaining in the raw materials of the biomass fuel, the dust particles will affect the use of the biomass fuel in the subsequent operation process, and will also penetrate into the interior of the equipment and cause damage to the equipment.

[0004] To this end, we propose a raw material crushing equipment for biomass fuel. Summary of the invention

[0005] The utility model aims to provide a raw material crushing device for biomass fuel, so as to solve the problem that the dust removal efficiency of the existing raw material crushing device for biomass fuel is not thorough.

[0006] To achieve the above purpose, the utility model provides the following solutions:

[0007] A raw material crushing device for biomass fuel comprises a crushing box, a feed box, a material turning mechanism and an exhaust mechanism, wherein the feed box is fixed on one side of the crushing box, a conveyor belt is arranged in the feed box, a driving wheel is arranged on the right side of the conveyor belt, a driven wheel is arranged on the right side of the conveyor belt, and the driving wheel is connected to a conveying motor arranged on the outside of the feed box; the material turning mechanism comprises a scraper, which is connected to the side wall of the feed box through a rotating shaft, and the scraper

[0008] The lower end of the conveyor belt contacts the upper surface of the conveyor belt; the exhaust mechanism includes a fan, an air duct and an air outlet, the fan is arranged on the upper wall of the feed box, one end of the air duct is connected to the air outlet of the fan, and the other end of the air duct is connected to the air outlet, and the air outlet is fixed on the side wall of the feed box. The dust particles in the material scraped by the scraper are sucked out through the mutual cooperation of the fan, the air duct and the air outlet.

[0009] Furthermore, a scattering mechanism and pulverizing blades are provided in sequence from top to bottom inside the pulverizing box, the pulverizing blades are connected to a pulverizing motor provided on the outside of the pulverizing box, a scattering drive pulley is provided on the rotating shaft of the pulverizing motor, and the scattering drive pulley is connected to a driven pulley provided on the outside of the scattering mechanism through a first belt.

[0010] Furthermore, in order to improve the breaking efficiency of the breaking mechanism, two breaking mechanisms are symmetrically provided.

[0011] Furthermore, the air outlet is a trumpet-shaped structure, the large end of the trumpet-shaped structure is connected to the side wall of the feed box, and the side wall of the large end of the trumpet-shaped structure is connected to the air outlet of the air duct, and the air duct guides the wind generated by the fan 401 into the trumpet-shaped structure.

[0012] Furthermore, a plurality of scrapers are provided along the moving direction of the conveyor belt, and an air outlet is provided on the side of each scraper.

[0013] Furthermore, during the working process, although the scraper can scrape up the dust particles on the conveyor belt, the dust particles are still at the bottom of the scraper, and some dust particles will still remain when the fan is working. For this reason, we have a flip connecting rod at the end of the connecting shaft between the scraper and the feed box, and one end of the flip connecting rod is connected to a driving connecting rod, which is connected to the upper surface of the driving turntable through a pin shaft, and a pulley is provided on the driving turntable, which is connected to the driving pulley on the conveying motor shaft through a belt; and a flip connecting rod is provided at the end of the connecting shaft between each scraper and the feed box, and two adjacent flip connecting rods are connected by a driven connecting rod.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] A raw material crushing equipment for biomass fuel. When the material falls onto the conveyor belt, fine dust particles will fall onto the surface of the conveyor belt along with the gaps between the materials. The dust particles on the surface of the conveyor belt are not easily sucked away by the dust removal fan. When the conveyor belt rotates, the scraper can scrape up the dust particles on the conveyor belt, and the scraped dust particles can be easily sucked away by the dust removal fan.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail in combination with the embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model content, and are not used to limit the utility model content. Example 1

[0024] In this embodiment, Figure 1-6As shown, a raw material crushing equipment for biomass fuel includes a crushing box 1, a feed box 2, a turning mechanism 3 and an exhaust mechanism 4. The feed box 2 is fixed on one side of the crushing box 1. A conveyor belt 201 is provided in the feed box 2. A driving wheel 202 is provided on the right side of the conveyor belt 201. A driven wheel 203 is provided on the right side of the conveyor belt 201. The driving wheel 202 is connected to a conveying motor 204 provided on the outer side of the feed box 2; the turning mechanism 3 includes a scraper 305, which is connected to the side wall of the feed box 2 through a rotating shaft, and the lower end of the scraper 305 is in contact with the upper surface of the conveyor belt 201. When the material falls on the conveyor belt, fine dust particles will fall to the surface of the conveyor belt along with the gaps between the materials. On the surface, the dust particles on the surface of the conveyor belt are not easily sucked away by the dust removal fan. When the conveyor belt 201 rotates, the scraper 305 can scrape up the dust particles on the conveyor belt 201, and the scraped dust particles can be easily sucked away by the dust removal fan; the exhaust mechanism 4 includes a fan 401, an air duct 402 and an air outlet 403. The fan 401 is arranged on the upper wall of the feed box 2, one end of the air duct 402 is connected to the air outlet of the fan 401, and the other end of the air duct 402 is connected to the air outlet 403. The air outlet 403 is fixed on the side wall of the feed box 2, and the dust particles in the material scraped up by the scraper 305 are sucked out through the mutual cooperation of the fan 401, the air duct 402 and the air outlet 403. The interior of the crushing box 1 is provided with a scattering mechanism 102 and a crushing blade 101 from top to bottom. The crushing blade 102 is connected to a crushing motor 104 provided on the outside of the crushing box 1. A scattering drive pulley 106 is provided on the rotating shaft of the crushing motor 104. The scattering drive pulley 106 is connected to a driven pulley 103 provided on the outside of the scattering mechanism 102 through a first belt 105.

[0025] In order to improve the dispersing efficiency of the dispersing mechanism 102, two dispersing mechanisms 102 are symmetrically provided. The air outlet 403 is a trumpet-shaped structure, the large end of the trumpet-shaped structure is connected to the side wall of the feed box 2, and the side wall of the large end of the trumpet-shaped structure is connected to the air outlet of the air guide 402, and the air guide 402 guides the wind generated by the fan 401 into the trumpet-shaped structure; since the air outlet 403 is a trumpet-shaped structure, a negative pressure area will be formed in the air outlet 403, and the dust particles in the material will be sucked out of the feed box 2 along with the wind in the air outlet 403. In order to improve the dust removal efficiency of the exhaust mechanism 4, an air outlet 403 is set on the side of each scraper 305. Example 2

[0026] In this embodiment, Figure 1-6As shown, during the working process, although the scraper 305 can scrape up the dust particles on the conveyor belt 201, the dust particles are still at the bottom of the scraper 305, and some dust particles will still remain when the fan 401 is working. For this reason, we have a flip link 307 at the end of the connection shaft between the scraper 305 and the feed box 2, and one end of the flip link 307 is connected to the driving link 303, and the driving link 303 is connected to the upper surface of the driving turntable 301 through the pin 306. The driving turntable 301 is provided with a pulley, and the pulley is connected to the driving pulley provided on the rotating shaft of the conveying motor 204 through the belt 302; and each end of the connection shaft between the scraper 305 and the feed box 2 is provided with a flip link 307, and two adjacent flip links 307 are connected by a driven link 304. During operation, the flip link 307 drives the scraper 305 to flip, and the dust at the bottom of the scraper 305 will be sucked out with the fan 401.
