Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection equipment, and in particular to a biomass energy micro-crushing device that integrates wind dust removal and evaporation drying. Background Art

[0002] In the field of biomass energy, crop straw, branches, leaves, grass and other materials are all usable biomass energy. In the process of producing biomass energy such as liquid fuel, they need to be fully pre-treated. However, there are very few biomass energy raw material processing machines, and the processing quality and efficiency are far from ideal. The development of new biomass energy material crushing machinery has a bright future.

[0003] At present, some existing pulverizers in China must use the induced draft system to assist in feeding biomass with a moisture content of 40%, otherwise it is easy to cause blockage, which will increase the power load accordingly, resulting in low output, low efficiency, high cost and other problems. At the same time, common pulverizers will produce a lot of dust when crushing materials, which cannot be well recycled and processed, causing pollution to the working environment and threatening the health of operators. In addition, the leakage of a large amount of dust causes problems such as low output and low efficiency of the pulverizer; the current pulverizer's pulverization mechanism cannot finely crush various raw materials into tiny particles according to the research needs of the materials. These tiny particles are significantly different from the raw materials in terms of physical, chemical and biological properties.

[0004] At present, most of the domestic crushing equipment is a unit operation machine, and the operation is still in the manual control stage. The limitations of manual control determine that the production effect of the equipment is difficult to meet high requirements. For example, when the crushing material conditions change, in order to produce particles of a specific particle size, the equipment often needs to be adjusted continuously. In this way, the particle size uniformity cannot be guaranteed, and the crushing efficiency and product effect are naturally affected. Manual control is also unable to respond quickly to emergencies, which limits the safety of the equipment.

[0005] For the pretreatment of biomass energy crushing process, there are very few traditional biomass energy raw material processing machines, and the processing quality and efficiency are far from ideal, requiring a lot of manpower, material and financial resources. Compared with traditional processing machines, the wind dust removal and evaporation drying integrated biomass energy micro-crushing device designed this time has the advantages of simple operation, energy saving and automatic crushing and drying production.

It is installed on the second fixed plate 12 and is located at the discharge end of the rough spherical grinding body 10; the outer ends of the connecting shafts of the two groups of curved knives 7 and one group of rough spherical grinding bodies 10 are connected with a transmission gear 6, and the transmission gear 6 is connected to the driving gear 11 fixed on the output shaft of the engine 9 by a chain 8, and the engine 9 is fixed on the stand 28.

[0028] The plurality of scimitars 7 form two rows and two columns of scimitar groups, which are operated by chains and gears. The same chain also drives the rough spherical grinding bodies 10 to work simultaneously, thereby achieving multi-stage crushing.

[0029] See also Figure 5 As shown, the wind dust removal environmental protection device comprises a vibrating conveyor belt 24 arranged in a frame 4, a blower 21 with two blower heads and a motor 22 for controlling the operation of the blower. One of the blower heads of the blower 21 is in the shape of a curved pipe and is connected to the bottom wall of the discharge end of the crushing bin 2 (a filter screen 20 is arranged on the connecting port), and the other blower head is arranged horizontally above the discharge end of the vibrating conveyor belt 24. A partition plate 23 with an upper surface inclined downward is arranged above the vibrating conveyor belt 24, and the partition plate 23 is fixed on the discharge port of the crushing bin 2; an annular dust collection cylinder 14 is sleeved on the outer wall of the crushing bin 2, and is connected to the crushing bin 2 by a plurality of connecting pipes. The internal space of the bin 2 is through-connected, and several connecting pipes are located between the curved blade 7 and the rough spherical grinding body 10. Several transmission pipes 15 are through-connected on the annular dust collection cylinder 14, and the several transmission pipes 15 are connected by air quick connectors 17. The transmission pipe 15 at the tail end passes through the baffle 19 suspended above the vibrating conveyor belt 24, and is arranged above the baffle 19. The baffle 19 is fixed on the frame 4 and bent downward, with the lower end adjacent to the vibrating end of the vibrating conveyor belt 24. The air pump 16 is through-connected to the transmission pipe 15; a foot pad 27 is provided on the supporting foot of the vibrating conveyor belt 24; and the right side wall of the frame 4 is through-connected to the dust outlet 29.

[0030] The annular dust collector 14 is located between the curved blade 7 and the rough spherical grinding body 10. The dust is sucked out by the power provided by the vacuum pump 6 and sent to the upper part of the baffle 19 until the dust outlet 29. The suction force of the annular dust collector 14 also disperses the material, which helps to fully grind the rough spherical grinding body 10. The blower 21 blows the upper dust in the crushing bin 2 to the top of the baffle 19 and finally enters the dust outlet 29. At the same time, the movement direction of the vibrating conveyor belt 24 points from the right end to the end with the chute 26. Under the action of vibration and the blower, secondary dust removal is carried out, and the dust will be discharged from under the baffle 19 until it reaches the dust outlet 29.

[0031] See also Figure 6As shown, the evaporative drying device includes a drying box 30 arranged below the vibrating conveyor belt 24, a water vapor collecting pipe 31 connected to the top of the drying box 30 and distributed in a matrix and in a sloped manner, and a drainage pipe 32 intersecting the water vapor collecting pipe 31 located at the lowest position of the slope, and the drainage pipe 32 is arranged outside the frame 4; the side wall of the drying box 30 is connected through the collecting funnel 25, and the collecting funnel 25 is located below the chute 26, and the chute 26 is obliquely fixed on the discharge end bracket of the vibrating conveyor belt 24; the inner bottom wall of the drying box 30 is inclined, and a discharge port 33 is opened at the lowest position, and a discharge funnel 35 is connected to the discharge port 33, and a discharge control valve plate 34 is arranged on the discharge funnel 35.

[0032] The material in the drying box 30 is dried by using a heating device, the evaporated water vapor enters the water vapor collecting pipe 31 and is discharged from the drainage pipe 32 , and the dried material is discharged from the discharge funnel 35 .

[0033] When the utility model is in use, biomass energy such as straw, branches, leaves, grass, etc. is put into the feed port 1, and is crushed in the crushing bin 2. The engine 9 drives the driving gear 11, so that the chain 8 drives several transmission gears 6, and then drives four groups of scimitars 7 arranged vertically and horizontally and the rough spherical grinding body 10 to crush. The vacuum pump 16 works, and the dust enters the annular dust suction cylinder 14 through the connecting pipe, and then enters the transmission pipe 15 and is discharged to the top of the baffle 19, so as to realize the preliminary dust removal work, which can not only effectively control the suction of dust, but also play the role of cooling, absorbing moisture and preventing material adhesion, thereby increasing the output and reducing energy consumption; the material crushed by the scimitar 7 falls into the rough spherical grinding body 10 for crushing again, and the material whose crushing size meets the conditions will pass through the mesh of the toothed plate screen 13. After the material passes through the toothed plate screen 13, due to the different quality of the crushed material and the dust, the quality of the dust is lighter than that of the material, and a blast port connected to the crushing bin 2 by the blower 21 will be located above The material is blown layer by layer to the top of the baffle 19 and finally enters the dust discharge port 29. The material passes through the slope of a certain angle of the partition 23 and falls on the vibrating conveyor belt 24 at a certain distance from the chute 26. Due to the vibration of the vibrating conveyor belt 24, the material can be lifted up to separate the material from the dust. Under the action of one of the horizontally arranged air outlets of the blower 21, the dust is blown away from the material and blown to the dust discharge port 29 to achieve final dust removal treatment and secondary dust removal. The material is driven by the vibrating conveyor belt 24 to finally reach the chute 26. The material falls into the collecting funnel 25 and enters the drying box 30. The moisture in the material is discharged by evaporation through the heating device in the drying box 30 to achieve the drying effect. The water vapor will reach the water vapor collecting pipe 31. Due to the slope structure of the water vapor collecting pipe 31, the water vapor will eventually condense into water and gather into the drainage pipe 32 to flow out. The dried material is discharged by opening the discharge control valve plate 34, completing the entire work process.

[0034] After adopting the above structure, the beneficial effects of this specific embodiment are as follows: The utility model provides a biomass energy micro-crushing device that integrates wind dust removal and evaporation drying. It does not require a lot of human intervention operations, provides convenience for the biomass energy crushing pretreatment work, and improves the efficiency of biomass energy pretreatment.
