Description

Technical Field

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

[0002] Biomass pellets are a type of solid biomass fuel. They are produced by crushing, drying, and extruding biomass raw materials to form pellets with a specific shape and density. Biomass pellets require screening during the production process.

[0003] In the prior art, such as Chinese patent CN216800519U, a biomass pellet fuel screening device is disclosed, including a processing frame. A fixing plate is provided at the upper middle of the left side of the inner cavity of the processing frame. A screening cylinder is provided on the right side of the fixing plate and the right side of the inner cavity of the processing frame. A fixing frame is provided at the upper middle of the right side of the outer cavity of the processing frame. A single-phase motor is fixedly installed in the middle of the right side of the inner cavity of the fixing frame via a mounting base. A rotating rod is provided at the output end of the single-phase motor. This utility model, through the inclined structure at the bottom of the processing frame, allows the screened material to fall to the bottom of the processing frame for discharge. The movable pull plate is pulled upwards to separate the bottom of the movable pull plate from the upper end of the L-shaped support block, making the discharge channel hollow. The inclined structure at the bottom of the processing frame automatically discharges the material accumulated at the bottom of the processing frame. The structure is simple, the operation is faster, and it also prevents material residue from remaining at the bottom of the processing frame.

[0004] Although the aforementioned patent has a simple structure and is easier to operate, and can prevent material residue from remaining at the bottom of the processing frame, biomass particles are prone to clogging inside the screen holes during the screening process, causing screen blockage, which in turn results in poor screen throughput and affects screening efficiency. Utility Model Content

[0005] The purpose of this utility model is to solve the problem in the above-mentioned patent that although the structure is simple and the operation is faster, and it can also prevent material residue from remaining at the bottom of the processing frame, biomass particles are easily blocked inside the screen holes during the screening process, causing screen blockage, which in turn leads to poor screen throughput and affects screening efficiency. Therefore, a biomass particle screening device is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a biomass pellet screening device, comprising a base, rotating seats symmetrically and fixedly connected to the top of the base, a screen cylinder rotatably connected between the inner surfaces of the two rotating seats, a first gear fixedly connected to one outer surface of the screen cylinder, a motor fixedly connected to the outer surface of one of the rotating seats, a second gear fixedly connected to the output end of the motor, and an auxiliary component provided between the tops of the two rotating seats.

[0007] The auxiliary component includes two connecting seats, a connecting rod rotatably connected between the inner surfaces of the two connecting seats, a cam fixedly connected to the center of the outer surface of the connecting rod, a transmission gear fixedly connected to one end of the connecting rod, a support block fixedly connected between the outer surfaces of the two connecting seats, multiple sliding rods movably passing through the top of the support block, a push block fixedly connected between the tops of the multiple sliding rods, a striking block fixedly connected between the bottoms of the multiple sliding rods, and multiple springs fixedly connected to the top of the striking block.

[0008] Preferably, the tops of the plurality of springs are fixedly connected to the top of the support block, the bottoms of the two connecting seats are respectively fixedly connected to the tops of the two rotating seats, and the outer surface of the transmission gear meshes with the outer surface of the first gear.

[0009] Preferably, the outer surface of the first gear meshes with the outer surface of the second gear, and a rotating shaft rotatably passes through the outer surface of one of the rotating seats.

[0010] Preferably, a third gear is fixedly connected to one end of the rotating shaft, and the third gear meshes with the second gear.

[0011] Preferably, a collecting hopper is fixedly connected between the outer surfaces of the two rotating seats, a first auger blade is fixedly connected to the inner surface of the screen cylinder, and a second auger blade is fixedly connected to the outer surface of the rotating shaft.

[0012] Preferably, the outer surface of another rotating seat is fixedly connected to a connecting pipe, and a collection box is provided on the outer surface of the rotating seat, wherein the outer surface of the second auger blade cooperates with the inner surface of the connecting pipe and the collection hopper.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, during the screening process, the first gear rotates and drives the transmission gear to rotate, causing the connecting rod and cam to rotate along the two connecting seats, pushing the push block back and forth. Under the action of the spring and sliding rod, the striking block moves up and down back and forth, striking the screen cylinder back and forth, knocking away the biomass particles blocking the screen cylinder mesh, thus ensuring screening efficiency.

[0015] 2. In this utility model, when the first gear is rotating, it will synchronously drive the third gear to rotate, so that the rotating shaft rotates along the rotating seat and the motor mounting seat. Therefore, the second auger blades will rotate in the collecting hopper and the connecting pipe, so that the biomass pellets move forward slowly and are then discharged through the connecting pipe. The discharge process is smoother and more controllable, and it is highly practical. Attached Figure Description

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1, as Figures 1-4As shown, this utility model provides a biomass pellet screening device, including a base 9. Rotary seats 6 are symmetrically fixedly connected to the top of the base 9. A screen cylinder 5 is rotatably connected between the inner surfaces of the two rotating seats 6. A first gear 1 is fixedly connected to the outer surface of one side of the screen cylinder 5. A motor 3 is fixedly connected to the outer surface of one of the rotating seats 6. A second gear 2 is fixedly connected to the output end of the motor 3. An auxiliary component 7 is arranged between the tops of the two rotating seats 6. The auxiliary component 7 includes two connecting seats 702. A connecting rod 704 is rotatably connected between the inner surfaces of the two connecting seats 702. A cam 703 is fixedly connected to the center position of the outer surface of the connecting rod 704. A transmission gear 701 is fixedly connected to one end of the rod 704. A support block 705 is fixedly connected between the outer surfaces of the two connecting seats 702. Multiple sliding rods 709 are movably passed through the top of the support block 705. A push block 706 is fixedly connected between the tops of the multiple sliding rods 709. A striking block 708 is fixedly connected between the bottoms of the multiple sliding rods 709. Multiple springs 707 are fixedly connected to the top of the striking block 708. The tops of the multiple springs 707 are all fixedly connected to the tops of the support block 705. The bottoms of the two connecting seats 702 are respectively fixedly connected to the tops of the two rotating seats 6. The outer surface of the transmission gear 701 meshes with the outer surface of the first gear 1.

[0024] The overall effect of Embodiment 1 is as follows: when biomass pellets need to be screened, the motor 3 is started, driving the second gear 2 to rotate, causing the first gear 1 to rotate synchronously. Therefore, the screen cylinder 5 rotates along the inner walls of the two rotating seats 6. Biomass pellets are then added to the screen cylinder 5 through the feeding hopper. With the assistance of the first auger blades 10 inside, the biomass pellets slowly move to the right and are screened. Qualified biomass pellets fall into the collection hopper 14, while unqualified pellets fall into the collection box 8, completing the screening of the biomass pellets. Simultaneously, during the rotation of the first gear 1, the transmission gear 701 is driven to rotate, causing the connecting rod 7... 04 rotates along the two connecting seats 702, so the cam 703 will rotate along the connecting rod 704. When the protrusion of the cam 703 rotates to the bottom, it will drive the push block 706 to push downward, causing the sliding rod 709 and the striking block 708 to move downward, and drive the spring 707 to stretch, so that the striking block 708 strikes the screen cylinder 5. When the protrusion of the cam 703 rotates to the top, under the action of the spring 707, it will drive the striking block 708 to reset. Therefore, under the reciprocating rotation of the cam 703, it will reciprocate to drive the striking block 708 to move up and down, and reciprocate to strike the screen cylinder 5, knocking away the biomass particles blocked inside the screen cylinder 5 mesh, ensuring the screening efficiency.

[0025] Example 2, as Figures 1-4As shown, the outer surface of the first gear 1 meshes with the outer surface of the second gear 2. A rotating shaft 13 is rotatably passed through the outer surface of one of the rotating seats 6. A third gear 4 is fixedly connected to one end of the rotating shaft 13. The third gear 4 meshes with the second gear 2. A collection hopper 14 is fixedly connected between the outer surfaces of the two rotating seats 6. A first auger blade 10 is fixedly connected to the inner surface of the sieve cylinder 5. A second auger blade 11 is fixedly connected to the outer surface of the rotating shaft 13. A connecting pipe 12 is fixedly connected to the outer surface of the other rotating seat 6. A collection box 8 is provided on the outer surface of the rotating seat 6. The outer surface of the second auger blade 11 cooperates with the inner surface of the connecting pipe 12 and the collection hopper 14.

[0026] The effect achieved by the entire embodiment 2 is that when the first gear 1 rotates, it will synchronously drive the third gear 4 to rotate, so that the rotating shaft 13 rotates along the rotating seat 6 and the motor mounting seat. Therefore, the second auger blade 11 will rotate in the collecting hopper 14 and the connecting pipe 12. Thus, when the qualified biomass pellets are screened, they will be collected through the collecting hopper 14 and slide along its inclined surface to the bottom. Then, they will slowly move forward through the rotation of the second auger blade 11 and be discharged through the connecting pipe 12, making the discharge process of biomass pellets smoother and more controllable, and with high practicality.

[0027] Working principle: When biomass pellets need to be screened, the motor 3 is started, driving the second gear 2 to rotate, causing the first gear 1 to rotate synchronously. Therefore, the screen cylinder 5 rotates along the inner walls of the two rotating seats 6. Biomass pellets are then added to the screen cylinder 5 through the feeding hopper. With the assistance of the first auger blades 10 inside, the biomass pellets slowly move to the right and are screened. Qualified biomass pellets fall into the collection hopper 14, while unqualified pellets fall into the collection box 8, completing the screening process. Simultaneously, as the first gear 1 rotates, it drives the transmission gear 701 to rotate, causing the connecting rod 704 to rotate along the two connecting seats 702. Therefore, the cam 703 rotates along the connecting rod 704. When the protrusion of the cam 703 rotates to the bottom, it drives the pusher block 706 downwards, causing the sliding rod 709 and the striking block 708 to move downwards. The spring 707 is stretched, causing the striking block 708 to strike the screen cylinder 5. When the protrusion of the cam 703 rotates to the top, the striking block 708 will be reset under the action of the spring 707. Therefore, the reciprocating rotation of the cam 703 will drive the striking block 708 to move up and down, striking the screen cylinder 5 repeatedly, knocking away the biomass particles blocked inside the mesh of the screen cylinder 5. When the first gear 1 rotates, it will drive the third gear 4 to rotate simultaneously, causing the rotating shaft 13 to rotate along the rotating seat 6 and the motor mounting seat. Therefore, the second auger blade 11 will rotate in the collecting hopper 14 and the connecting pipe 12. Thus, the qualified biomass particles will be collected through the collecting hopper 14 and slide along its inclined surface to the bottom. Then, they will slowly move forward through the rotation of the second auger blade 11 and be discharged through the connecting pipe 12, making the discharge process of biomass particles smoother and more controllable, and more practical.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
