Technical Field

[0001] The utility model relates to the technical field of dust removal and feeding, in particular to a closed dust removal and feeding system. Background Art

[0002] During the production process, factories use a variety of materials, some of which are relatively small. During the loading process of such materials, dust is often easily caused to fly, which not only pollutes the environment and affects the health of workers, but also causes material loss.

[0003] At present, some existing feeding devices on the market will cause a large amount of dust and materials to fly in the air, and are unable to separate the dust from the materials, resulting in dust mixed in the materials, affecting product quality and making it inconvenient to feed materials from the bottom up.

[0004] Therefore, the present application provides a closed dust removal and feeding system to overcome the defects of the prior art. Utility Model Content

[0005] The utility model aims to solve the problem that the existing feeding device causes a large amount of dust to fly, is unable to strip the dust from the material, and is inconvenient to feed the material upward from the bottom.

[0008] As a preferred technical solution, the stirring part includes a motor, which is fixed on the top of the silo, and the output end of the motor is downward and connected to a transmission shaft, and a paddle is fixedly connected to the transmission shaft. The transmission shaft and the paddle are arranged in the silo, and a bracket is provided under the silo, and the silo is mounted on the bracket; the motor drives the paddle to rotate through the transmission shaft, which is convenient for mixing different materials and also facilitates the uniform descent of materials.

[0009] As a preferred technical solution, pipeline two is fixedly connected between the air inlet of the cyclone separator and the air outlet of the vacuum pump, and pipeline three is fixedly connected between the feed port of the silo and the discharge port of the storage section; the material in the storage section enters the silo through pipeline three to realize automatic feeding, and the material will not fly to the outside, avoiding the phenomenon of dust flying in the factory. The vacuum pump brings the air in the silo and the floating dust and material into the cyclone separator through pipeline two. In the cyclone separator, the material will be separated and fall into the storage section, while the dust and air will be discharged.

[0010] As a preferred technical solution, a dust collector is fixedly connected to the top of the negative pressure part, and the dust collector is a bag dust collector. A pipeline four is fixedly connected between the air inlet of the dust collector and the air outlet at the top of the cyclone separator; when the dust-laden airflow in the cyclone separator passes through the dust collector, the dust therein will be intercepted, and the cleaned airflow will be discharged into the air.

The negative pressure part can create a negative pressure in the silo, causing the silo to automatically suck the material in the storage part, thereby realizing an automatic loading process. Since the negative pressure is generated in the silo, the device can realize automatic loading even when feeding the material from a low place to a high place. Except for the final exhaust link, the other links of the device are in a closed state, which can avoid the phenomenon of the material flying around to the greatest extent. The vacuum pump discharges the extracted air into the cyclone separator for separation, which can separate the material from the air and fall back into the storage part, thereby reducing the waste of material and reducing the dust content in the material.

[0021] In order to make the technical means, technical features, purposes and technical effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments; based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work should fall within the scope of protection of the present invention.

[0022] Example 1

[0023] As attached Figure 1 To the attached Figure 2 As shown: A closed dust removal and feeding system includes a negative pressure part 1, characterized in that: one side of the negative pressure part 1 is fixedly connected to a storage part 5, but the two are not connected, and the top of the storage part 5 is fixedly connected to a cyclone separator 3, which belongs to the existing technology and has been widely used in industry, so it is not described here. The air inlet on one side of the cyclone separator 3 is fixedly connected to the air outlet of the negative pressure part 1, and one side of the negative pressure part 1 is fixedly connected to a silo 4 through a pipeline. The silo 4 is connected to the storage part 5 through a pipeline, and a stirring part 6 is fixedly connected to the silo 4. The stirring part 6 can stir the materials in the silo 4 so that the materials are evenly mixed and the material is discharged conveniently. The bottom of the silo 4 is fixedly connected to the air lock 2, and the air lock 2 can control the feeding by opening and closing. The negative pressure part 1 extracts the air in the silo 4 and discharges it to the cyclone separator 5 to separate the material and the dust. The separated material falls back into the storage part 5. The air in the silo 4 is extracted to form a negative pressure, and then the material in the storage part 5 is absorbed to realize automatic feeding. Moreover, the material can be fed from a low place to a high place without causing a large amount of dust to fly in the air.

[0024] The negative pressure part 1 includes a vacuum pump 11, the air intake of the vacuum pump 11 is fixedly connected to a pipeline 12, the other end of the pipeline 12 is fixedly connected to the air outlet at the top of the silo 4, and part of the pipeline 12 passes through the material storage part 5. The vacuum pump 11 extracts air from the silo 4 through the pipeline 12, thereby forming a negative pressure in the silo 4.

[0025] A pipeline 2 31 is fixedly connected between the air inlet of the cyclone separator 3 and the air outlet of the vacuum pump 11. Part of the pipeline 2 31 passes through the material storage part 5. The air extracted by the vacuum pump 11 is mixed with materials and dust. The extracted air enters the cyclone separator 3 through the pipeline 2 31. The bottom of the cyclone separator 3 is connected to the material storage part 5. The separated material in the cyclone separator 3 will eventually fall into the material storage part 5. A pipeline 3 42 is fixedly connected between the feed port of the silo 4 and the discharge port of the material storage part 5. The material in the storage silo 5 enters the silo 4 through the pipeline 3 42.

[0026] The stirring part 6 includes a motor 61, which is fixed to the top of the silo 4. The output end of the motor 61 is downward and connected to a transmission shaft 62. A paddle 63 is fixedly connected to the transmission shaft 62. The transmission shaft 62 and the paddle 63 are arranged in the silo 4. The motor 61 drives the paddle 63 to rotate through the transmission shaft 62, thereby stirring the materials in the silo 4 and fully mixing the various materials. A bracket 41 is provided under the silo 4, and the silo 4 is mounted on the bracket 41. The bracket 41 is used to stably support the silo 4 to prevent the silo 4 from collapsing.

[0027] Working method: Start the vacuum pump 11, which extracts air from the silo 4, forming a negative pressure in the silo 4, and then automatically absorbs the material in the storage part 5. The air extracted by the vacuum pump 11 is mixed with material and dust and is sent to the cyclone separator 3 for separation. After the material is separated, it finally falls into the storage part 5, reducing material loss. The separated gas and dust are discharged into the air, which can reduce the dust in the material and thus reduce the impact on the quality of the finished product.

[0028] Example 2

[0029] Although the first embodiment has been able to solve the original technical problems and achieve the desired effect, we found that since the cyclone separator 3 is located above the material storage part 5 and the gas ejected from the gas outlet of the cyclone separator 3 contains some dust, when workers add materials to the material storage part 5, they are often disturbed by the dust, which has a certain impact on the workers' health. Therefore, we have made the following improvements based on the first embodiment:

[0030] As attached Figure 3 To the attached Figure 6 As shown: the top of the negative pressure part 1 is fixedly connected to a dust collector 7, and the dust collector 7 is a bag dust collector. The bag dust collector is a mature existing technology and is not described here. The air inlet of the dust collector 7 is fixedly connected to a pipeline four 71, and the other end of the pipeline four 71 is fixedly connected to the top air outlet of the cyclone separator 3.

[0031] Working method: The gas ejected from the air outlet at the top of the cyclone separator 3 enters the dust collector 7 through pipeline 4 71. The dust contained in the gas is filtered and cleaned in the dust collector 7. After completion, the gas is discharged from the air outlet of the dust collector 7.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the scope of implementation of the present invention. That is, all equivalent changes and modifications made according to the content of the patent application scope of the present invention should fall within the technical scope of the present invention.
