DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-3 A biomass pellet forming machine includes a forming machine body 1, a feed hopper 11 and a discharge hopper 12 installed on the forming machine body 1, and a dust removal mechanism installed on the forming machine body 1 and used to remove dust in the feed hopper 11 and the discharge hopper 12. The forming machine body 1, the feed hopper 11 and the discharge hopper 12 constitute an existing biomass pellet forming machine, referred to as a biomass pellet machine, whose internal structure and principle have been disclosed and will not be repeated here. When the forming machine body 1 processes biomass pellets, it is usually crushed first and then shaped. At this time, the dust generated during the crushing and shaping process is easy to drift from the inside of the forming machine body 1 to the feed hopper 11 and the discharge hopper 12, and the forming machine body 1 is also easy to generate dust due to material collision during feeding and discharging.

[0023] See also Figure 2-3The dust removal mechanism includes a dust removal box 2 fixedly arranged on the outer wall of the forming machine body 1, an air suction component arranged at one end of the dust removal box 2, a plurality of dust suction pipes 22 fixedly arranged at the other end of the dust removal box 2 and connected with the feed hopper 11 and the discharge hopper 12, and a filter 23 fixedly arranged at the middle part of the inner wall of the dust removal box 2 for filtering dust. The air suction component includes a suction fan 21 fixedly arranged on the top of one end of the dust removal box 2, and a connecting pipe fixedly arranged between the suction end of the suction fan 21 and the inner wall of the dust removal box 2. The suction fan 21 is a fan with a suction effect such as a negative pressure fan and an exhaust fan. After the suction fan 21 is running, it will cooperate with the dust suction pipe 22 to suck the dust scattered into the feed hopper 11 and the discharge hopper 12 into the dust removal box 2. At this time, the filter 23 can filter the air containing dust and block the dust.

[0024] See also Figure 2-3 A dust collecting mechanism is provided at the bottom inner side of the dust removal box 2 for collecting dust blocked by the filter screen 23 when the suction assembly stops rotating. The dust collecting mechanism comprises a dust collecting hopper 3 fixedly arranged at the bottom of one end of the dust removal box 2 close to the dust suction pipe 22, and a dust collecting pipe 31 fixedly arranged at the bottom end of the dust collecting hopper 3. A dust collecting bottle 32 is detachably provided on the outer wall of the bottom end of the dust collecting pipe 31. The dust collecting bottle 32 can be installed at the bottom end of the dust collecting pipe 31 by means of threaded connection or the like. When the suction fan 21 stops rotating, the dust blocked by the filter screen 23 will enter into the dust collecting bottle 32 through the dust collecting hopper 3 and the dust collecting pipe 31 with gravity, and the dust will be collected centrally by the dust collecting bottle 32.

[0025] See also Figure 2-3 A cleaning mechanism is movably provided in the dust box 2 for dredging the filter 23 and covering the top opening of the dust collecting mechanism. The cleaning mechanism includes a square rod 4 movably arranged in the dust box 2, a counterweight plate 41 fixedly arranged on the outer wall of the square rod 4 for covering the top opening of the dust collecting hopper 3, and a plurality of bristles 42 fixedly arranged on one side of the counterweight plate 41 and plugged into the holes of the filter 23. People can drive the counterweight plate 41 and the bristles 42 and other components to move up and down by pushing and pulling the square rod 4 up and down. After the bristles 42 move, the filter 23 can be dredged. When the counterweight plate 41 naturally hangs down, it will abut against the top opening of the dust collecting hopper 3, thereby covering the top opening of the dust collecting hopper 3 to prevent the dust collected in the dust collecting mechanism from being sucked to the side of the filter 23 after the suction fan 21 is running.

[0026] See also Figure 2-3 A grip ring 43 located outside the dust removal box 2 is fixedly provided at the top of the square rod 4, and people can hold the grip ring 43 to push and pull the square rod 4 up and down.

[0027] See also Figure 2-3A rubber plug 44 that is compatible with the dust collecting tube 31 is fixed at the bottom end of the square rod 4. The rubber plug 44 is located in the dust collecting bottle 32. The rubber plug 44 will move up and down with the square rod 4. When the rubber plug 44 moves up, it will enter the compatible dust collecting tube 31. Since the highest point of the rubber plug 44 moving up is located in the dust collecting tube 31, the negative pressure generated after the rubber plug 44 moves cannot send the dust in the dust collecting bottle 32 to the dust removal box 2. When the rubber plug 44 moves down until it enters the dust collecting bottle 32, negative pressure will be generated at the top of the dust collecting tube 31, thereby sucking the dust brushed off by the bristles 42 into the dust collecting bottle 32 through the dust collecting tube 31 like a syringe, thereby improving the dust collection effect.

[0028] Working principle: When in use, the suction fan 21 is turned on. After the suction fan 21 is running, it will cooperate with the dust suction pipe 22 to suck the dust in the feed hopper 11 and the discharge hopper 12 into the dust removal box 2. At this time, the filter 23 can filter and block the dust, thereby performing dust removal, so that the dust generated during the processing of the forming body 1 is not easy to float into the outside air, reducing pollution and not affecting people's health;

[0029] After the suction fan 21 stops rotating, people can hold the grip ring 43 to drive the square rod 4 to push up and down, so as to drive the counterweight plate 41, the bristles 42 and the rubber plug 44 to move up and down. After the bristles 42 move, they can dredge the filter 23. When the counterweight plate 41 hangs down naturally, it will cover the top opening of the dust hopper 3 to prevent the dust collected in the dust collecting mechanism from being sucked to the side of the filter 23 when the suction fan 21 is running. When the rubber plug 44 moves up and then down, it can cooperate with the corresponding dust collecting pipe 31 to suck the dust brushed by the bristles 42 into the dust collecting bottle 32 like a syringe, thereby improving the dust collection effect and facilitating people to remove the dust collecting bottle 32 later to remove the collected dust in a centralized manner.

[0030] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
