[0002] Biomass fuel: refers to the burning of biomass materials as fuel, which is generally mainly agricultural and forestry waste, which is different from fossil fuels. In the national policies and environmental protection standards, direct burning of biomass is a highly polluting fuel and is only used in large stoves in rural areas and is not allowed in cities. The application of biomass fuel is actually mainly biomass molding fuel, which uses agricultural and forestry waste as raw materials, and is made into various shapes through crushing, mixing, extrusion, drying and other processes. It is a new type of clean fuel that can be directly burned. A lot of dust will be generated during the crushing process.

[0003] Existing Chinese patent: A dust removal device, patent number: CN214680754U, the dust removal device includes: a sealing mechanism, which is used to seal and connect with the equipment to be dusted; a dust raising component, which is arranged in the sealing mechanism and is used to raise the dust on the surface of the equipment; a dust suction mechanism, which is used to absorb the raised dust; a spray component, which is used to spray water mist to make the dust fall into the dust collecting mechanism; a dust collecting mechanism, which is located below the spray component, and the dust collecting mechanism is provided with an exhaust port, which is used to discharge the gas after dust removal. The dust removal device of the present application has a high degree of automation, can improve the dust removal efficiency, and can achieve comprehensive sealed dust removal to avoid pollution to the environment.

[0022] The embodiment of the present application provides a dust collector for a pulverizer, which effectively solves the technical problem that the above-mentioned dust removal device needs to be sealed and connected to the pulverizer before it can be used, but after sealing, the material to be pulverized cannot be put in, so the dust removal device cannot be used for the pulverizer. A universal wheel is installed at the bottom of the mobile frame, which can be moved. After the dust box is moved to the top of the equipment, the two threaded rods are rotated. Since the threaded rods are connected to the dust box by threads, the dust box will rotate up and down when the threaded rods rotate. After the height of the dust box is adjusted to the top of the pulverizer hopper, it can be used. The position of the dust box is adjusted by pushing the mobile frame or rotating the threaded rod, which achieves the effect of easy installation and use. The material is put into the grinder from the feed port on the dust box. The dust generated by the grinder when the material is crushed will spread inside the dust box. The suction force generated by the start-up of the fan will suck the dust inside the dust box into the dust collecting box through the suction pipe. The dust entering the dust collecting box will be filtered by the filter and remain in the dust collecting box. The filtered air will be discharged through the fan. During the discharge process, the air will be divided into two parts by the diverter, one part will be discharged, and the other will be discharged by two blow boxes through the blow pipe. The angle of the blow box can be adjusted. The air discharged from the blow box can prevent the dust from overflowing from the feed port. The dust is controlled inside the dust box by the fan and then sucked into the dust collecting box from the dust box, achieving the effect of dust removal suitable for the grinder.

[0023] Example

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the technical solution in the embodiment of the present application effectively solves the technical problem that the dust removal device mentioned above needs to be sealed and connected to the pulverizer before it can be used, and the material to be pulverized cannot be put in after sealing, so the dust removal device cannot be used for the pulverizer. The overall idea is as follows:

[0025] In view of the problems existing in the prior art, the utility model provides a dust collector applied to a pulverizer, including a mobile frame 1, a dust box 2 is slidably installed on the top of the mobile frame 1, two blow boxes 3 are symmetrically rotatably installed on both sides of the dust box 2, and two threaded rods 11 are symmetrically threadedly installed on both sides of the dust box 2.

[0026] The end of the threaded rod 11 is rotatably connected to the movable frame 1, an air suction pipe 4 is fixedly installed on the top of the dust box 2, an air blowing pipe 5 is fixedly installed on the side end of the blow box 3, a dust collecting box 6 is fixedly installed on the top of the movable frame 1, and a filter screen 13 is fixedly installed inside the dust collecting box 6.

[0027] A fan 7 is fixedly installed on the side end of the filter 13, and a diverter 8 is fixedly installed on the bottom end of the fan 7; the side end of the diverter 8 is connected to the end of the air blowing pipe 5, a dust box 9 is slidably installed on the bottom end of the dust box 6, and four universal wheels 12 are fixedly installed on the bottom end of the mobile frame 1.

[0028] Working principle:

[0029] In the first step, a universal wheel 12 is installed at the bottom of the mobile frame 1, which can be moved. After the dust box 2 is moved to the top of the equipment, the two threaded rods 11 are rotated. Since the threaded rods 11 are connected to the dust box 2 by threads, the dust box 2 will rotate up and down when the threaded rods 11 rotate. After the height of the dust box 2 is adjusted to the top of the crusher hopper, it can be used. The position of the dust box 2 is adjusted by pushing the mobile frame 1 or rotating the threaded rods 11, which achieves the effect of easy installation and use.

[0030] The second step is to put the material into the crusher from the feed port on the dust box 2 after the installation. The dust generated by the crusher when the material is crushed will spread inside the dust box 2. The suction force generated by the start-up of the fan 7 will suck the dust inside the dust box 2 into the dust box 6 through the suction pipe 4. The dust entering the dust box 6 will be filtered by the filter 13 and remain in the dust box 6. The filtered air will be discharged through the fan. During the discharge process, the air will be divided into two parts by the diverter 8, one part will be discharged, and the other part will be discharged by the two blowing boxes 3 through the blowing pipe 5. The angle of the blowing box 3 can be adjusted. The air discharged from the blowing box 3 can prevent the dust from overflowing from the feed port. The dust is controlled inside the dust box 2 by the fan 7 and then sucked into the dust box 6 from the dust box 2, thereby achieving the effect of dust removal suitable for the crusher.

[0031] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
