Description

Technical Field

[0001] The utility model relates to the technical field of insulating material production, in particular to a dust removal device and system. Background Technique

[0002] The production process adopted for high-voltage insulating materials is the post-suction process. Its characteristics are that after particle processing and granulation, steps such as sieving, weighing, heating, absorbing additives, and cooling are required. During these steps, the material needs to be stirred and transported many times. During the stirring and transportation process, the particles will rub against the pipe wall. After a long time of friction, the particles will be worn and powder will be carried out. As the powder drifts everywhere, a lot of powder will be brought into the finished material.

[0003] On the one hand, these powders will block the pneumatic conveying filter, resulting in unsmooth material transportation. On the other hand, powder caking will occur in the remaining dead corners inside the production line or equipment, contaminating the finished product. In addition, these powders also have an impact on the material properties. For example: (1) Reducing insulation performance: Dust may form a conductive channel in the insulating material, thereby reducing its insulation performance and increasing the risk of electric leakage and breakdown. (2) Affecting mechanical properties: Dust may cause non-uniformity of the insulating material, thereby affecting its mechanical properties, such as tensile strength, elongation at break, etc. Affecting appearance quality: (3) Dust may form spots and defects on the surface of the insulating material, thereby affecting its appearance quality.

[0020] Embodiment 1

[0021] Combined with the attached Figures 1-3 , this embodiment proposes a dust removal device, which includes a housing 10 with an inner cavity. A feed inlet 11 is provided on the upper side of the housing 10, a discharge outlet 12 is provided on the lower side of the housing 10, and an air outlet 13 is provided on one side of the housing 10. The feed inlet 11, the discharge outlet 12, and the air outlet 13 are all communicated with the inner cavity. A plurality of staggered flow channels 14 are arranged from top to bottom in the inner cavity. The flow channels 14 are densely distributed with air holes. A plurality of air inlets 15 are provided on the housing 10, and each air inlet 15 is located below the corresponding flow channel 14.

[0022] The dust removal device of this embodiment is used to remove powder formed by the wear of particles during the material conveying process, thereby preventing powder impurities from contaminating the product, improving product quality, reducing downtime due to powder blockage, and improving production efficiency. At the same time, due to the provision of the dust removal device, the cost of manual cleaning can also be further saved.

[0023] The dust removal device of this embodiment is arranged in a system such as material conveying, and is generally installed in a vertical pipe, that is, the feed port 11 is located at the upper side and connected to the vertical pipe at the upper side, and the discharge port 12 is located at the lower side and connected to the vertical pipe at the lower side. The material conveying process is that the material enters the feed port 11 from the upper vertical pipe under the influence of its own weight, and after the dust is removed in the housing 10, it enters the lower vertical pipe from the discharge port 12.

[0024] Based on the above-mentioned setting form, the working principle of the dust removal device of this embodiment is as follows: after the insulating material particles and other materials enter the inner cavity of the shell 10, they will fall on the flow channel 14 and move along the staggered flow channels 14. The staggered flow channels 14 can slow down the falling speed of the particles and spread the particles. At the same time, the air inlet 15 continuously passes the air flow, and the air flow will pass through the dense pores on the flow channel 14 from bottom to top, thereby blowing up the powder attached to the particles. Since the mass of the particles is much greater than the mass of the powder, the particles will not be blown, and the blown powder will eventually be discharged from the air outlet 13 along with the air flow, so as to achieve the separation of materials and dust.

[0025] In a further embodiment, an adjusting member may be provided at the air inlet 15, such as a valve body, which can adjust the flow rate of the air inlet 15, thereby adjusting the blowing power of the powder. In an optional embodiment, the adjusting member is a slider 16 movably provided at the air inlet 15, and the sliding of the slider 16 can change the degree of shielding of the air inlet 15, thereby affecting the opening of the air inlet 15, and the flow rate of the air inlet 15 can be adjusted.

[0026] In addition, in some embodiments, a plurality of cleaning windows 17 are provided on the housing 10, and the cleaning windows 17 can be used to clean the inside of the dust removal device without removing the dust removal device. For example, in one embodiment, at least one cleaning window 17 is provided on the lower side of any flow channel 14, thereby cleaning the powder accumulated on the lower side of the flow channel 14 that cannot be swept by the airflow. In another embodiment, at least one cleaning window 17 is provided at the air outlet 13, thereby specifically cleaning the dust naturally accumulated at the air outlet 13 or adsorbed by static electricity. It is conceivable that a closure member 18 should be movably provided near the cleaning window 17 on the outside of the housing 10 to open or close the cleaning window 17, and the closure member 18 may be a baffle that is hinged or slidably provided.

[0027] Example 2

[0028] Combined with the attached drawings Figures 1-3 In this embodiment, a system is proposed, which includes a dust removal device according to Embodiment 1, and further includes a fan 19, at least one filter 20, and a dust collector 21. The air outlet of the fan 19 is respectively connected to each air inlet 15. The filter 20 is arranged on the communication path between the fan 19 and each air inlet 15. The dust collector 21 is connected to the air outlet 13, the air outlet 13 is connected to the air inlet of the dust collector 21, and the air outlet of the dust collector 21 is connected to the air inlet 15 of the fan 19.

[0029] Based on the aforementioned dust removal device, this embodiment further provides a system, which can be regarded as a system for conveying materials or a system for removing dust. The working principle is to adjust the power of the fan 19, that is, to adjust the air intake of each air inlet 15, so as to ensure that in the dust removal device, the wind can blow up the dust without affecting the falling of the material. The air outlet 13 carries the dust to flow to the dust collector 21, and the dust can be collected by the dust collector 21, and then further enter the air inlet of the fan 19, and be blown out from the air outlet of the fan 19, and then re-enter the inner cavity of the housing 10 through the air inlet 15 to form a circulation loop. Among them, the air flow passing through the dust collector 21 may still carry a small amount of fine dust, and at this time, it can be further filtered by the filter 20 connected to the fan 19.

[0030] The above schematically describes the present invention and its embodiments. This description is not restrictive. What is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. Therefore, if those of ordinary skill in the art are inspired by it and design similar structural forms and embodiments to this technical solution without creative work without departing from the purpose of the present invention, they shall fall within the protection scope of the present invention.
