Description

Technical Field

[0001] This utility model relates to the field of biomass fuel technology, and in particular to a biomass fuel pelletizing device. Background Technology

[0002] Biomass fuel pellets are regular cylindrical solid fuels made by compressing agricultural and forestry waste (such as sawdust, straw, rice husks, etc.). The raw materials include wood processing residues, fruit shells and kernels, agricultural and forestry by-products, crop straw, and urban solid waste that have been physically processed into dense pellets. This fuel has the characteristics of high calorific value, low sulfur content, and high combustion efficiency. Biomass fuel pelleting equipment is a mechanical device that processes agricultural and forestry waste into high-density pellet fuel through crushing, drying, and high-pressure extrusion. This equipment is widely used in home heating, industrial boilers, and biomass power generation, and has the advantages of high resource utilization and strong environmental protection.

[0003] When using small biomass fuel pelleting equipment, biomass is usually poured manually from the inlet into the feed hopper. If too much biomass is poured in at once, it will clog the inlet and reduce the pelleting efficiency of the equipment. This requires manual, uniform, and slow pouring of biomass. The process of manually pouring biomass in a uniform and slow manner is long and cumbersome. Therefore, a biomass fuel pelleting equipment is proposed. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the existing technology that pouring too much biomass at once will clog the feed inlet and reduce the pelleting efficiency of the pelleting equipment. This requires manual, uniform, and slow pouring of biomass, which is a long and cumbersome process. Therefore, this invention proposes a biomass fuel pelleting equipment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A biomass fuel pelletizing device includes a shell, a feed hopper fixedly connected to the upper part of the shell, a grid plate fixedly connected inside the feed hopper, a plurality of spherical protrusions fixedly connected to the inner side of the feed hopper, a rotating rod rotatably connected inside the grid plate, an agitator fixedly connected to the end of the rotating rod, sliders symmetrically slidably connected inside the agitator, springs fixedly connected to the sides of two sliders, sliding rods symmetrically fixedly connected to the outer sides of two sliders, and a plurality of fixed rods fixedly connected to the sides of the sliding rods. The rotation of the agitator causes the plurality of fixed rods to slide back and forth along the direction of the agitator. The rotation of the agitator and the back and forth sliding of the plurality of fixed rods can disperse the biomass poured on the grid plate and make the biomass fall evenly through the grid plate into the extrusion equipment.

[0006] The above technical solution further includes: A servo motor is fixedly connected to the bottom of the housing. The output end of the servo motor is fixedly connected to the rotating rod, and the servo motor can drive the rotating rod to rotate.

[0007] An extrusion device is provided on the outside of the rotating rod, and a discharge port is fixedly connected to the side of the outer shell. The rotation of the rotating rod can drive the extrusion device to work, and the extruded biomass fuel pellets can fall out through the discharge port.

[0008] The size of the symmetrical openings at both ends of the stirring rod is adapted to the size of the slider, and both sliders can slide within the symmetrical openings inside the stirring rod.

[0009] The size of the symmetrical openings on the side of the stirring rod is adapted to the size of the sliding rod. Multiple sliding rods are slidably connected to the stirring rod. The sliding rod moves back and forth inside the stirring rod, causing the sliding rod to move back and forth within the openings on the side of the stirring rod. The back and forth movement of the sliding rod causes multiple fixed rods to move back and forth along the direction of the stirring rod. The back and forth movement of the fixed rods can disperse the biomass.

[0010] The stirring rod is fixedly connected to the spring. When the slider contacts the spherical protrusion by rotating the stirring rod, the slider will be squeezed into the opening inside the stirring rod, which will compress the spring. When the slider leaves the spherical protrusion, the spring will rebound and drive the slider away from the opening inside the stirring rod. The stirring rod is movably connected to the grid plate. The rotation of the stirring rod can disperse the biomass.

[0011] The slider is movably connected to the spherical protrusion. When the slider contacts the spherical protrusion, it will be squeezed into the opening inside the stirring rod.

[0012] This utility model has the following beneficial effects: In this invention, through the cooperation of the slider and the spherical protrusion, when the stirring rod rotates, the slider drives multiple fixed rods to slide back and forth along the opening direction inside the stirring rod. The rotation of the stirring rod and the back and forth sliding of the multiple fixed rods can disperse the biomass poured on the grid plate and make the biomass fall evenly through the grid plate into the extrusion equipment, thus eliminating the need for manual and even pouring of biomass.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figure 1 - Figure 5 As shown, the present invention proposes a biomass fuel pelletizing device, including a shell 1, a feeding hopper 2 fixedly connected to the upper part of the shell 1, a grid plate 3 fixedly connected inside the feeding hopper 2, a plurality of spherical protrusions 4 fixedly connected to the inner side of the feeding hopper 2, a rotating rod 6 rotatably connected inside the grid plate 3, an agitator 7 fixedly connected to the end of the rotating rod 6, sliders 8 symmetrically slidably connected inside the agitator 7, springs 9 fixedly connected to the sides of the two sliders 8, sliding rods 10 symmetrically fixedly connected to the outer sides of the two sliders 8, and a plurality of fixed rods 11 fixedly connected to the sides of the plurality of sliding rods 10. The rotation of the agitator 7 drives the plurality of fixed rods 11 to slide back and forth along the direction of the agitator 7. The rotation of the agitator 7 and the back and forth sliding of the plurality of fixed rods 11 can disperse the biomass poured on the grid plate 3 and make the biomass fall evenly through the grid plate 3 into the extrusion device 12.

[0017] A servo motor 5 is fixedly connected to the bottom of the outer casing 1. The output end of the servo motor 5 is fixedly connected to the rotating rod 6, and the servo motor 5 can drive the rotating rod 6 to rotate.

[0018] An extrusion device 12 is provided on the outside of the rotating rod 6, and a discharge port 13 is fixedly connected to the side of the outer shell 1. The rotation of the rotating rod 6 can drive the extrusion device 12 to work, and the extruded biomass fuel pellets can fall out through the discharge port 13.

[0019] The size of the symmetrical openings at both ends of the stirring rod 7 is adapted to the size of the slider 8, and both sliders 8 can slide within the symmetrical openings inside the stirring rod 7.

[0020] The size of the symmetrical openings on the side of the stirring rod 7 is adapted to the size of the slide rod 10. Multiple slide rods 10 are slidably connected to the stirring rod 7. The slide rod 10 is driven to slide back and forth in the openings on the side of the stirring rod 7 by the sliding block 8 sliding back and forth inside the stirring rod 7. The back and forth sliding of the slide rod 10 drives multiple fixed rods 11 to move back and forth along the direction of the stirring rod 7. The back and forth movement of the fixed rods 11 can disperse the biomass.

[0021] The stirring rod 7 is fixedly connected to the spring 9. When the slider 8 contacts the spherical protrusion 4 by the rotation of the stirring rod 7, the slider 8 will be squeezed into the opening inside the stirring rod 7, which will compress the spring 9. When the slider 8 leaves the spherical protrusion 4, the spring 9 will rebound and drive the slider 8 to leave the opening inside the stirring rod 7. The stirring rod 7 is movably connected to the grid plate 3. The rotation of the stirring rod 7 can disperse the biomass.

[0022] The slider 8 is movably connected to the spherical protrusion 4. When the slider 8 contacts the spherical protrusion 4, it will be squeezed into the opening inside the stirring rod 7.

[0023] In this embodiment, after the crushed biomass is poured onto the grid plate 3, the servo motor 5 drives the rotating rod 6 to rotate, which in turn drives the extrusion device 12 to work. At the same time, the rotating rod 6 drives the stirring rod 7 to rotate, which in turn drives the two sliders 8 to rotate. When the two sliders 8 rotate, they will contact the spherical protrusion 4 and be squeezed into the opening inside the stirring rod 7. At this time, both springs 9 are compressed. After the two sliders 8 rotate away from the spherical protrusion 4, both springs 9 will rebound, causing the two sliders 8 to leave the opening inside the stirring rod 7. The two sliders 8 are inside the stirring rod 7. The reciprocating sliding of the opening of the part will cause the two slide rods 10 to reciprocate in the opening on the side of the stirring rod 7. The reciprocating sliding of multiple slide rods 10 will cause multiple fixed rods 11 to reciprocate in the direction of the stirring rod 7. Through the rotation of the stirring rod 7 and the reciprocating sliding of multiple fixed rods 11, the biomass poured on the grid plate can be dispersed and the biomass can be evenly poured into the extrusion equipment through the grid plate, thus eliminating the need for manual even pouring of biomass. Then, the extrusion equipment 12 will extrude the biomass into biomass fuel pellets. The extruded biomass fuel pellets will fall out from the discharge port 13.
