Description

Technical Field

[0001] This utility model relates to the field of feeding equipment, and in particular to a feeding device for gypsum powder production. Background Technology

[0002] Gypsum powder is a material widely used in construction, medicine, art, and other fields. It is mainly made from natural gypsum ore through processes such as crushing, calcination, and grinding. Its production process mainly includes raw material pretreatment, calcination, grinding, homogenization, and packaging. In the feeding process after grinding, gypsum powder needs to be transported from the grinding mill to the next process (such as a homogenization silo or packaging machine) via conveying equipment. Bucket elevators are commonly used as vertical conveying equipment in this process. Bucket elevators lift materials from the bottom to the top using buckets fixed to chains or belts. They have advantages such as compact structure, high conveying efficiency, and small footprint, making them particularly suitable for the vertical conveying of powdery materials.

[0003] However, existing gypsum powder feeding devices still have some problems when using bucket elevators. For example, patent application CN202022940071.3 discloses a feeding device for gypsum powder production, which uses a bucket elevator to achieve vertical material conveying. However, in practical applications, during the discharge process, due to the small size and light weight of the gypsum powder particles, dust is easily generated under the action of airflow or mechanical vibration. This not only causes dust to permeate the production workshop, polluting the working environment and increasing cleaning and maintenance costs, but also poses a potential hazard to the respiratory health of operators. At the same time, the flying dust leads to material loss, reduces production efficiency, and increases production costs. In addition, if the emitted dust is directly discharged into the atmosphere without effective collection and treatment, it will also pollute the surrounding environment, which does not meet the strict environmental protection requirements of modern industrial production. Therefore, this application proposes a feeding device for gypsum powder production to solve the above problems. Utility Model Content

[0004] The main purpose of this utility model is to provide a feeding device for gypsum powder production, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A feeding device for gypsum powder production includes a bucket elevator. A discharge pipe is fixedly installed on the upper part of the bucket elevator. A material-binding assembly is sleeved on the discharge pipe. The material-binding assembly includes a material-binding pipe. A dust removal assembly is fixedly installed on the discharge pipe and the material-binding pipe. The dust removal assembly consists of a dust-collecting fan, a dust-collecting pipe, a protective barrier, and a dust filter. The dust-collecting pipe is fixedly connected to the dust-collecting fan. The protective barrier and the dust filter are both fixedly installed on the inner wall of the dust-collecting pipe. The material-binding pipe surrounds the discharge port to prevent dust diffusion. The dust removal assembly adsorbs flying dust through negative pressure, filters it, and discharges clean air. Through the cooperation of the material-binding assembly and the dust removal assembly, efficient conveying and dust control of gypsum powder are achieved, reducing dust pollution, improving the working environment, and reducing material loss.

[0007] Preferably, a feed bucket is fixedly installed at the lower part of the bucket elevator, which serves as a material inlet and works with the bucket elevator to complete vertical conveying.

[0008] Preferably, the material-bundling pipe on the material-bundling assembly is fixedly sleeved on the lower part of the discharge pipe, and a connecting slot is provided on the lower part of one side wall of the material-bundling pipe. The connecting slot penetrates the inner and outer sides of one side wall of the material-bundling pipe, and provides an installation interface for the dust removal pipe, forming a sealed dust collection channel to achieve dust collection, ensure that dust is efficiently sucked into the dust removal system, and prevent it from escaping.

[0009] Preferably, one end of the bundled material pipe on the bundled material assembly is fixedly installed with a connecting bracket by welding. The connecting bracket is also fixedly installed on the bucket elevator by bolts. The connecting bracket is used to fix the bundled material pipe, ensure structural stability, and prevent the bundled material pipe from loosening or shifting.

[0010] Preferably, the dust collection fan on the dust removal assembly is fixedly installed at one end of the discharge pipe by bolts, and an air inlet pipe is fixedly installed on the dust collection fan. The dust collection fan is connected to the dust removal pipe through the air inlet pipe to form an airflow, provide negative pressure, and adsorb dust.

[0011] Preferably, the dust removal pipe on the dust removal assembly is fixedly connected to the air inlet pipe fixedly installed on the dust collection fan by bolts. The dust removal pipe is also fixedly inserted into the connection slot opened on one side wall of the bundled material pipe, and the dust removal pipe and the bundled material pipe are fixedly connected by welding. The dual fixing method of bolts and welding enhances the sealing and stability, ensures the seamless connection between the dust removal system and the bundled material assembly, prevents dust leakage, and improves dust removal efficiency.

[0012] Preferably, the protective barrier, dust filter assembly, and material feeding pipe on the dust removal component are detachably fixedly connected by bolts. The protective barrier blocks large particles, and the dust filter assembly filters fine particles.

[0013] Preferably, the dust filtration component is located inside the protective barrier net, and one end of the protective barrier net is on the same plane as the inner wall of one side of the material-bundling pipe. The protective barrier net first intercepts large particles, and the dust filtration component performs fine filtration, optimizing the dust filtration path and reducing airflow resistance.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] (1) By setting up a dust removal assembly consisting of a dust extraction fan, dust removal pipe, protective barrier net and dust filter assembly, the flying dust generated during the gypsum powder discharge process can be effectively collected, significantly reducing the dust concentration in the workshop, improving the working environment, reducing cleaning and maintenance costs, reducing material loss, improving production efficiency, reducing production costs, and the filtered clean air can be directly discharged to meet environmental protection requirements.

[0016] (2) By setting up a material-binding component on the discharge pipe, the material-binding pipe can form a closed surrounding structure for the discharge port of the discharge pipe, which can effectively block the spread of dust and ensure the smooth fall of materials through a specific angle guide design. Combined with the negative pressure dust collection effect of the dust removal component, the efficient collection of dust can be achieved. Attached Figure Description

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments. Example 1:

[0023] Please see Figure 1 , Figure 2As shown, the feeding device for gypsum powder production includes a bucket elevator 1. A discharge pipe 2 is fixedly installed on the upper part of the bucket elevator 1. A material-binding assembly 3 is sleeved on the discharge pipe 2. The material-binding assembly 3 includes a material-binding pipe 6. A feed hopper 5 is fixedly installed on the lower part of the bucket elevator 1. During operation, the raw materials to be fed are placed into the feed hopper 5. Then, as the bucket elevator 1 works, it will transport the raw materials in the feed hopper 5 to the discharge pipe 2. Finally, the raw materials will fall through the discharge pipe 2 into the material-binding pipe 6 on the material-binding assembly 3 under the influence of gravity. After being guided by the material-binding pipe 6, the raw materials will fall into the processing equipment. At the same time, the material-binding pipe 6 forms a sealed enclosure structure around the discharge port of the discharge pipe 2, which can effectively prevent dust diffusion.

[0024] Specifically, the material-binding pipe 6 on the material-binding assembly 3 is fixedly sleeved on the lower part of the discharge pipe 2, and a connecting slot 8 is opened on the lower part of one side wall of the material-binding pipe 6. The connecting slot 8 penetrates the inner and outer sides of one side wall of the material-binding pipe 6. A connecting bracket 7 is fixedly installed at one end of the material-binding pipe 6 on the material-binding assembly 3 by welding. The connecting bracket 7 is also fixedly installed on the bucket elevator 1 by bolts. By setting the material-binding assembly 3 on the discharge pipe 2, its material-binding pipe 6 can form a sealed surrounding structure for the discharge port of the discharge pipe 2, which can effectively block the spread of dust and ensure the smooth fall of materials through a specific angle guide design. Combined with the negative pressure dust collection effect of the dust removal assembly 4, the efficient collection of dust can be achieved. Example 2:

[0025] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a dust removal assembly 4 is fixedly installed on the discharge pipe 2 and the bundled material pipe 6. The dust removal assembly 4 consists of a dust collection fan 9, a dust removal pipe 10, a protective barrier net 11, and a dust filter assembly 12. The dust removal pipe 10 is fixedly connected to the dust collection fan 9. The protective barrier net 11 and the dust filter assembly 12 are both fixedly installed on the inner wall of the dust removal pipe 10. When working, the dust collection fan 9 on the dust removal assembly 4 needs to be started. At this time, the dust blocked by the bundled material pipe 6 will be sucked into the dust removal pipe 10 by the negative pressure generated by the dust collection fan 9. At this time, the protective barrier net 11 and the dust filter assembly 12 will block and filter the dust. Then, the air filtered by the protective barrier net 11 and the dust filter assembly 12 will be discharged by the dust collection fan 9.

[0026] Specifically, the dust collection fan 9 on the dust collection assembly 4 is fixedly installed at one end of the discharge pipe 2 by bolts. An air inlet pipe 13 is fixedly installed on the dust collection fan 9. The dust collection pipe 10 on the dust collection assembly 4 is fixedly connected to the air inlet pipe 13 fixedly installed on the dust collection fan 9 by bolts. The dust collection pipe 10 is also fixedly inserted into a connecting slot 8 opened on one side wall of the bundled material pipe 6, and the dust collection pipe 10 and the bundled material pipe 6 are fixedly connected by welding. The protective barrier net 11 and the dust filter assembly 12 on the dust collection assembly 4 are detachably fixedly connected to the bundled material pipe 6 by bolts. The dust filter assembly 12 is located inside the protective barrier net 11, and one end of the protective barrier net 11 is connected to the bundled material pipe 6. The inner wall of one side of the material pipe 6 is on the same plane. The dust collection fan 9 of the dust removal component 4 needs to be selected with an appropriate power model according to the actual production needs to ensure that the negative pressure generated is sufficient to effectively adsorb the flying dust in the material pipe 6. The protective barrier net 11 is made of stainless steel woven mesh with a mesh count of 80-100 mesh. Its function is to intercept larger gypsum powder particles and prevent them from directly entering the dust removal pipe 10 and causing blockage. The dust filter component 12 should have a filtration accuracy of PM2.5 level to ensure that fine dust is fully intercepted. The protective barrier net 11 and the dust filter component 12 need to be disassembled, replaced and cleaned regularly according to the usage to ensure that the dust removal component 4 always maintains a good performance.

[0027] Finally, by setting up a dust removal component 4 consisting of a dust extraction fan 9, a dust removal pipe 10, a protective barrier net 11, and a dust filter component 12, the flying dust generated during the gypsum powder discharge process can be effectively collected, significantly reducing the dust concentration in the workshop, improving the working environment, reducing cleaning and maintenance costs, reducing material loss, improving production efficiency, and reducing production costs. At the same time, the filtered clean air can be directly discharged, meeting environmental protection requirements.

[0028] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
