Abstract
Description
Technical Field
[0001] This utility model relates to the field of biomass pulverization technology, specifically a biomass pulverization system. Background Technology
[0002] To recycle biomass, it is necessary to pulverize and recycle it. Pulverization technology is a prerequisite for the energy utilization of biomass. Traditional pulverization technology simply transports biomass to a certain location and then uses pulverization equipment for coarse pulverization, which reduces pulverization efficiency and biomass utilization efficiency. Existing biomass pulverization devices are not sealed structures, so a large amount of dust is generated during processing, causing environmental pollution. Furthermore, the biomass pulverization process carries hard, heavy objects that can damage the pulverizer, making it inconvenient to use. Utility Model Content
[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a biomass pulverizing system with simple structure and easy operation. It can process in a completely closed environment, avoiding dust pollution generated during the production process, and can effectively remove hard and heavy objects from the raw materials, avoiding damage to the pulverizer. It can effectively solve the problems in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a biomass pulverizing system, including a belt conveyor, which is inclined, with the discharge end of the belt conveyor connected to an arched feed pipe, the biomass discharge port of the arched feed pipe connected to the feed port of a water droplet pulverizer, the water droplet pulverizer mounted on a pulverizer frame, the outlet of the water droplet pulverizer connected to a centrifugal separator via a pipe, the upper air outlet of the centrifugal separator connected to the inlet of a negative pressure fan via a pipe, the outlet of the negative pressure fan connected to the inlet of a bag filter via a conduit, the lower dust outlet of the bag filter connected to a shut-off valve, and the lower outlet of the centrifugal separator also connected to a shut-off valve, with a powder conveying auger positioned horizontally below the two shut-off valves, and two feed ports on the powder conveying auger, each connected to the lower opening of one of the two shut-off valves.
[0005] Furthermore, the arched feed pipe includes an arched feed channel with a rectangular cross-section. One end of the feed channel is provided with a biomass outlet, and the other end is provided with a heavy material outlet. A feed inlet is also provided on the side of the feed channel. The raw material is transported into the feed channel by a belt conveyor. When the negative pressure airflow draws in the raw material, iron and heavier impurities are discharged from the heavy material outlet, while the raw material enters the water droplet pulverizer through the arched feed channel.
[0006] Furthermore, the centrifugal separation device includes a separation shell with a conical lower end. An air outlet pipe is installed in the middle of the interior of the separation shell, and the upper end of the air outlet pipe extends to the upper end of the separation shell. A spiral guide vane is provided between the outer side of the air outlet pipe and the inner side of the separation shell. An inlet is provided in the tangential direction at the upper side of the separation shell. The interior of the separation shell is drawn in by a negative pressure fan to create a negative pressure, thereby drawing the raw material pulverized inside the water droplet pulverizer into the separation shell. The spiral guide vane causes the raw material entering the separation shell to flow in a spiral motion, while the solid raw material is concentrated in the center and enters the powder conveying auger from the airlock.
[0007] Furthermore, the powder conveying auger includes a conveying shell, inside which a spiral feeding roller is provided, and at one end of the conveying shell is a conveying motor that drives the spiral feeding roller to rotate. The operation of the conveying motor can drive the spiral feeding roller to rotate, and the rotation of the spiral feeding roller can convey the raw materials.
[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: A negative pressure fan draws air from the inside of the separation shell, creating a negative pressure environment. A belt conveyor transports the raw material into the feeding channel. When the negative pressure airflow draws in the raw material, iron and heavier impurities are discharged from the heavy material outlet, while the raw material enters the teardrop-type pulverizer through the arched feeding channel. The pulverized material is then drawn into the separation shell. Spiral guide vanes cause the material entering the separation shell to flow in a spiral pattern, and solid material is concentrated at the center before the air is turned off. The biomass fragments enter the auger conveyor, and some of them are carried by the negative pressure fan into the bag filter to separate the dust and gas. The separated biomass fragments and dust then enter the auger conveyor. The conveyor motor drives the screw feed roller to rotate, which in turn conveys the raw material, thus completing the processing. This biomass crushing system has a simple structure and is easy to operate. It can process in a completely enclosed environment, avoiding dust pollution during production and effectively removing hard and heavy objects from the raw material, thus preventing damage to the crusher.

One end of the feed channel 21 is provided with a biomass outlet 22, and the other end is provided with a heavy material outlet 24. The side of the feed channel 21 is provided with a feed inlet 23. The raw materials are transported to the feed channel 21 by the belt conveyor 1. Inside the 1st stage, when the negative pressure airflow draws in the raw material, iron and heavier impurities are discharged from the heavy material inlet 24, while the raw material enters the water droplet pulverizer 3 through the arched feed channel 21. The centrifugal separation device 4 includes a separation shell 41, the lower end of which is conical. An air outlet 42 is installed in the middle of the interior of the separation shell 41, and the upper end of the air outlet 42 extends to the upper end of the separation shell 41. A spiral guide vane 43 is provided between the outer side of the air outlet 42 and the inner side of the separation shell 41. An inlet is provided tangentially at the upper side of the separation shell 41. The negative pressure fan 5 draws the interior of the separation shell 41 to create a negative pressure, thereby drawing in the pulverized raw material inside the water droplet pulverizer 3. The raw material is taken into the separation shell 41 and guided by the spiral guide vanes 43 to flow in a spiral pattern. Solid raw materials are concentrated in the center and enter the powder conveying auger 8 through the airlock 7. The powder conveying auger 8 includes a conveying shell 81, inside which a spiral feeding roller 82 is installed.
