Description

Technical Field

[0001] The utility model relates to the technical field of conveying equipment, in particular to a feeding and conveying device of a pulverizer. Background Art

[0002] In today's biomass fuel production, raw materials come from a wide range of sources and are diverse in nature, encompassing a rich array of bio-based resources such as agricultural and forestry waste, crop straw, wood processing residues, and fruit shells. These raw materials exhibit diverse forms and physical properties, depending on their natural growth environments and processing methods. In particular, wood processing residues are often mixed with ferrous metals such as nails and wood screws. The presence of these ferrous metals poses significant challenges to the subsequent biomass fuel production process.

[0003] Specifically, when wood processing residues containing metal parts are directly transported to the crusher for crushing, the metal parts come into intense contact with the blades inside the crusher, which can easily lead to increased wear of the blades and significantly shorten their service life. At the same time, metal parts may collide with or get stuck in the screen during the crushing process, causing the screen to be damaged or even completely fail, seriously affecting the normal operation and screening effect of the crusher. In the long run, frequent equipment maintenance or replacement not only increases the cost of biomass fuel production, but is also likely to lead to a significant decline in production efficiency, hindering the healthy development of the biomass energy industry. In view of this, how to effectively process the materials transported to the crusher in the biomass fuel production process and remove the iron and metal objects therein has become a technical problem that needs to be solved urgently in the industry.

[0005] In order to solve the above technical problems, the technical solution of the utility model is:

[0006] The transmission mechanism that this transmission mechanism is used for the transmission mechanism is that this transmission mechanism is used to transmit the transmission mechanism to the transmission mechanism, and this transmission mechanism is used to transmit the transmission mechanism to the transmission mechanism.

[0007] Preferably, a maintenance platform is installed on one side of the frame, and a guardrail is installed on the maintenance platform.

[0008] Preferably, the magnetic block is connected to the frame through a connecting rod.

[0009] Preferably, the metal strip is fixedly connected to the conveyor belt 2 by bolts.

[0010] Preferably, the discharge trough is a plastic trough.

[0011] Preferably, the discharge chute is fixed to the frame by bolts.

[0012] Preferably, the angle between the second conveyor belt and the first conveyor belt is 90°.

[0013] The above technical solution has the following advantages:

[0014] The present utility model effectively solves the problems of equipment loss and decreased production efficiency caused by the mixing of ferrous metal objects into raw materials in the production of biomass fuels. Through innovative design, it realizes the efficient separation of ferrous metal objects from biomass raw materials, ensures that the materials input into the crusher are pure and free of ferrous metal objects, effectively protects the production equipment from the impact and wear of ferrous metal objects, significantly extends the service life of the equipment, and ensures the continuity and stability of the biomass fuel production process, thereby achieving a dual improvement in economic and environmental benefits. The present utility model adopts magnetic separation technology in the process of removing ferrous metal objects. Once the ferrous metal objects are magnetically adsorbed and separated from the raw materials, they can be promptly desorbed from the metal strips and fall into a dedicated discharge trough and discharged in time, avoiding the accumulation of ferrous metal objects on the metal strips and the phenomenon of magnetic attenuation. This instant desorption and discharge mechanism ensures the long-term and high efficiency of magnetic rejection, and further enhances the ability of the present utility model to efficiently intercept ferrous metal objects in the production of biomass fuels.

[0020] The following further describes specific embodiments of the present invention in conjunction with the accompanying drawings. It should be noted that the descriptions of these embodiments are intended to aid understanding of the present invention and do not constitute limitations on the present invention. Furthermore, the technical features involved in the various embodiments of the present invention described below may be combined with one another as long as they do not conflict with one another.

[0021] As shown in the accompanying drawings, a feeding and conveying device of a crusher comprises a frame 1, a conveyor belt 3 mounted on the frame 1 through a driving roller 2, and a reduction motor 4 mounted on the frame 1 and connected to one of the driving rollers 2; the frame 1 is fixedly connected to a frame body 5, a conveyor belt 2 7 is mounted on the frame body 5 through a driving roller 6, a reduction motor 2 8 is mounted on the frame 1, and the conveying end of the reduction motor 2 8 is connected to one of the driving rollers 6; the conveyor belt 2 7 is located above the conveyor belt 3 and the conveying of the two is connected. The conveying direction forms a certain angle, and the angle is preferably 90°; the two ends of the conveyor belt 2 7 extend out from both sides of the width direction of the conveyor belt 1 3 respectively; a number of metal strips 9 are fixedly connected to the surface of the conveyor belt 2 7 at intervals; a magnetic block 10 is fixedly connected to the frame 5, and the magnetic block 10 is located between the upper and lower belts of the conveyor belt 2 7 and close to the lower belt surface; the size of the magnetic block 10 in the width direction of the conveyor belt 3 is not less than the width of the conveyor belt 3; a discharge trough 11 is fixedly connected to the frame 1 and located below one end of the conveyor belt 2 7.

[0022] As a further improved technical solution of this embodiment, in order to facilitate the inspection and maintenance of the conveying device, an inspection platform 13 is installed on one side of the frame 1, and a guardrail 14 is installed on the inspection platform 13.

[0023] As a specific technical solution of this embodiment, the magnetic block 10 is connected to the frame 5 via a connecting rod 12, which facilitates the maintenance of the magnetic block 10.

[0024] As a specific technical solution of this embodiment, the metal strip 9 is fixedly connected to the conveyor belt 2 7 by bolts to facilitate the disassembly, assembly and maintenance of the metal strip 9.

[0025] As a specific technical solution of this embodiment, the discharge chute 11 is a plastic chute, which can effectively reduce the impact sound of iron and metal objects, thereby reducing workshop noise. The discharge chute 11 is fixedly connected to the frame 1 by bolts to facilitate disassembly and maintenance of the discharge chute 11.

[0026] During operation, conveyor belt 1 (3) transports the biomass raw materials normally and feeds them into the crusher. Reducer motor 2 (8) also operates synchronously, driving conveyor belt 2 (7) to rotate. When metal strip 9 is located below magnetic block 10, magnetic block 10 transmits magnetic force to metal strip 9, which then attracts ferrous metal objects in the raw materials on conveyor belt 1 (3). Metal strip 9 moves along conveyor belt 2 (7). When metal strip 9 leaves the area covered by magnetic block 10, it loses its magnetism. The ferrous metal objects on it naturally fall off into the discharge chute 11 below and are discharged from the discharge chute 11, thus eliminating the ferrous metal objects in the raw materials.

[0027] This utility model utilizes magnetic separation technology to remove ferrous metal objects. Once magnetically attracted and separated from the raw material, ferrous metal objects are promptly desorbed from the metal strip 9 and dropped into a dedicated discharge chute 11 for immediate discharge, preventing the accumulation of ferrous metal objects on the strip 9 and the resulting magnetic attenuation. This immediate desorption and discharge mechanism ensures sustained and efficient magnetic removal, further enhancing the utility model's ability to effectively intercept ferrous metal objects in biomass fuel production.

[0028] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It is apparent to those skilled in the art that various changes, modifications, substitutions, and variations to these embodiments may be made without departing from the principles and spirit of the present invention, and these changes and modifications still fall within the scope of protection of the present invention.
