Description

Technical Field

[0001] This utility model relates to a biomass fuel screw feeding anti-blocking mechanism, belonging to the field of screw feeder technology. Background Technology

[0002] A screw feeder for biomass fuel is a device that transports biomass fuel using a screw feeder. The screw feeder is a new generation product integrating stable flow conveying, weighing, and quantitative control of powder materials. It is suitable for continuous metering and batching of powder materials in various industrial production environments. It adopts multiple advanced technologies, ensuring reliable operation and high control precision. It is particularly suitable for continuous metering and batching of powder materials in industries such as building materials, metallurgy, power, and chemicals. It is suitable for horizontal or inclined conveying of powdery, granular, and small lump materials, such as coal, ash, slag, cement, and grain, with a material temperature below 200℃. It is not suitable for conveying easily perishable, highly viscous, or easily agglomerated materials.

[0003] Biomass fuel refers to fuel made by burning biomass materials, primarily agricultural and forestry waste (such as straw, sawdust, bagasse, and rice husks). It differs from fossil fuels in that it uses agricultural and forestry waste as raw materials, which are then processed through crushing, mixing, extrusion, and drying to produce various shapes (such as blocks and pellets) that can be directly burned.

[0004] Because the materials in biomass fuel are relatively fine, during the screw conveying process, the fuel is prone to bridging at the feed inlet, which can prevent smooth feeding. This bridging phenomenon causes blockages at the feed point, requiring manual clearing before feeding can continue. This leads to poor feeding uniformity, increases safety hazards, and makes it difficult to achieve stable and continuous transport of biomass fuel. Moreover, most blockages are caused by clumping of biomass fuel. Even after clearing the blockage and continuing to feed, clumped biomass fuel may still result in uneven quality due to clumping, affecting the subsequent processing quality of the biomass fuel. It is also difficult to break up clumped fuel during transport. Utility Model Content

[0005] This invention provides a biomass fuel screw feeding anti-blocking mechanism to solve the technical problem of easy blockage when biomass fuel is conveyed by a screw feeder.

[0006] This utility model solves the above-mentioned technical problems through the following technical solutions:

[0007] This utility model provides a biomass fuel screw feeder anti-blocking mechanism, comprising:

[0008] The machine body has a drive shaft rotatably connected inside, and a variable pitch spiral disk is fixedly connected to the surface of the drive shaft. A biomass fuel feeding hopper is fixedly installed on the top side of the machine body. An adjustment component is provided at the bottom of the feeding hopper. A linkage component is provided inside the machine body located on the side of the feeding hopper. The linkage component is drivenly connected to one end of the drive shaft and is located below the adjustment component.

[0009] In this technical solution, one end of the machine body is fixedly connected to the drive motor via a reducer, and the drive motor is connected to one end of the drive shaft via the reducer.

[0010] In this technical solution, a discharge port is fixedly connected to one side of the bottom of the machine body, and a funnel-shaped feeding hopper is provided on the other side of the top of the machine body.

[0011] In this technical solution, the adjusting component is composed of a housing, which is fixedly connected to the outer wall of the bottom of the feeding hopper. A baffle is fitted and slidably inside the housing, and one end of a screw is rotatably connected inside the baffle, with the other end of the screw threadedly connected to the inside of the housing.

[0012] In this technical solution, the shell is a flat structure, the width of the shell is the same as the outer diameter of the bottom of the hopper, the width of the baffle is the same as the inner diameter of the bottom of the hopper, and the end of the baffle is a semi-circular structure that fits against the inner wall of the hopper.

[0013] In this technical solution, the baffle has inclined surfaces distributed on both the upper and lower surfaces, and the inclined surface at the bottom of the baffle is distributed correspondingly to the extrusion plate.

[0014] In this technical solution, a stirring motor is fixedly installed on the side wall of the feeding hopper, the output end of the stirring motor is fixedly connected to the stirring shaft, and the stirring shaft extends into the inside of the feeding hopper and is located above the baffle.

[0015] In this technical solution, an arc-shaped partition is fixedly connected inside the machine body. The partition is located on one side of the feeding hopper, and a drive shaft is sealed and rotated in the middle of the partition.

[0016] In this technical solution, the linkage component consists of a rotating shaft and an end face gear. The linkage component is located on one side of the partition plate.

[0018] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.

[0019] The positive and progressive effects of this utility model are as follows:

[0020] The aforementioned biomass fuel screw feeding anti-clogging mechanism utilizes a machine body to transport biomass fuel. During feeding via a hopper, baffles adjust the feeding speed, allowing for appropriate adjustments based on feeding needs. A stirring shaft clears the feeding area, eliminating bridging and preventing blockages. A screw conveyor enables continuous transport; a variable-pitch screw enhances initial pushing force and reduces material density at the outlet, preventing excessive compression and agglomeration. The screw's drive mechanism continuously moves the extrusion plate, which, via a linkage component, moves back and forth within the hopper. This staggered engagement of the extrusion plate and baffles crushes agglomerated biomass fuel, ensuring uniform biomass fuel production and improving subsequent production quality and feeding efficiency.

[0026] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0027] like Figure 1-3 As shown, the biomass fuel screw feeder anti-clogging mechanism includes:

[0028] The machine body 1 has a drive shaft 3 rotatably connected inside it. A variable pitch spiral disk 4 is fixedly connected to the surface of the drive shaft 3. A biomass fuel feeding hopper 7 is fixedly installed on the top side of the machine body 1. An adjustment component is provided at the bottom of the feeding hopper 7. A linkage component is provided inside the machine body 1 located on the side of the feeding hopper 7. The linkage component is connected to one end of the drive shaft 3 and is located below the adjustment component. An extrusion plate 19 is inserted through the side wall of the feeding hopper 7 below the adjustment component and is movably connected to the linkage component.

[0029] One end of the machine body 1 is fixedly connected to the drive motor 6 via a reducer 5, and the drive motor 6 is connected to one end of the drive shaft 3 via the reducer 5; a discharge port 2 is fixedly connected to one side of the bottom of the machine body 1, and a funnel-shaped feeding hopper 7 is provided on the other side of the top of the machine body 1.

[0030] In this technical solution, the drive motor 6 drives the drive shaft 3 to rotate stably after being reduced by the reducer 5. When the spiral disk 4 rotates, it pushes the biomass fuel to the discharge port 2 to realize the feeding operation. The biomass fuel is transported through the feeding hopper 7. The use of the variable pitch spiral disk 4 can improve the pushing force in the initial stage and reduce the pushing and squeezing force near the discharge port 2 to prevent agglomeration.

[0031] The adjusting assembly consists of a housing 8, which is fixedly connected to the bottom outer wall of the feeding hopper 7. A baffle 10 is slidably fitted inside the housing 8, and one end of a screw 9 is rotatably connected inside the baffle 10. The other end of the screw 9 is threadedly connected to the inside of the housing 8. The housing 8 has a flat structure, and its width is the same as the outer diameter of the bottom of the feeding hopper 7. The width of the baffle 10 is the same as the inner diameter of the bottom of the feeding hopper 7, and the end of the baffle 10 has a semi-circular structure and fits against the inner wall of the feeding hopper 7. The baffle 10 has inclined surfaces on both its upper and lower surfaces, and the inclined surface at the bottom of the baffle 10 corresponds to the extrusion plate 19.

[0032] In this technical solution, after biomass fuel is put into the hopper 7, the screw 9 is rotated. The screw 9 extends from the shell 8 and drives the baffle 10 to move into the shell 8, thereby increasing the gap between the baffle 10 and the hopper 7 to increase the feeding speed. The biomass fuel falls from one side of the baffle 10. When feeding is not required, the baffle 10 is closed to seal the bottom of the hopper 7.

[0033] A stirring motor 11 is fixedly installed on the side wall of the feeding hopper 7. The output end of the stirring motor 11 is fixedly connected to the stirring shaft 12, and the stirring shaft 12 extends into the feeding hopper 7 and is located above the baffle 10. An arc-shaped partition 13 is fixedly connected inside the machine body 1. The partition 13 is located on one side of the feeding hopper 7, and a drive shaft 3 is sealed and rotated in the middle of the partition 13.

[0034] In this technical solution, when biomass fuel is conveyed in the feeding hopper 7, the stirring is started to drive the stirring shaft 12 to rotate continuously inside the feeding hopper 7, so that the biomass fuel will not be blocked at the feeding hopper 7, thus solving the problem that agglomeration in biofuel is prone to blockage at the outlet of the feeding hopper 7.

[0035] The linkage assembly consists of a rotating shaft 15 and an end face gear 14. The linkage assembly is located on one side of the partition plate 13. The end face gear 14 is fixedly connected to the end of the drive shaft 3. The rotating shaft 15 is rotatably connected to the top of the machine body 1, and both ends of the rotating shaft 15 are fixedly connected to the transmission gear 16 and the turntable 17, respectively. The transmission gear 16 meshes with the end face gear 14. The edge of the turntable 17 is connected to one end of the connecting rod 18, and the other end of the connecting rod 18 is connected to the extrusion plate 19. The linkage assembly is located on one side of the feeding hopper 7. The other side of the feeding hopper 7 is provided with a housing 8, and the extrusion plate 19 is correspondingly located below the baffle 10.

[0036] In this technical solution, the partition 13 facilitates the continuous delivery of biofuel. When the drive shaft 3 rotates, it drives the end face gear 14 to rotate synchronously, which in turn drives the transmission gear 16 to rotate. When the rotating shaft 15 rotates on the machine body 1, it drives the turntable 17 to rotate synchronously. When the turntable 17 rotates, it drives the connecting rod 18 to swing continuously, which in turn drives the extrusion plate 19 to move back and forth inside the feeding hopper 7. When the extrusion plate 19 moves, it causes the biofuel to move between the extrusion plate 19 and the baffle 10. When the extrusion plate 19 is close to the baffle 10, it can crush the clumped biofuel, avoiding clumping and affecting subsequent production.

The protection scope of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the protection scope of this utility model.
