Description

Technical Field

[0001] The utility model relates to the field of dust collection devices, and more specifically, to a dust collection device for boron carbide production. Background Technique

[0002] During the production process of boron carbide, a large amount of dust and particulate matter are generated. These dusts will not only cause serious pollution to the production environment, affect the health of operators, but also may lead to equipment damage and reduction of production efficiency. With the continuous improvement of environmental protection requirements and the development of production technology, higher requirements are put forward for dust collection in the boron carbide production process. As an efficient dust collection device, the cyclone dust collection device has gradually received attention. It uses the action of centrifugal force to separate dust particles in the dust-containing air flow, realizing the collection and purification of dust.

[0003] At present, although the existing cyclone dust collection devices have good dust separation effects, they are not very thorough in separating dust with smaller particle sizes. As a result, the air discharged from the air outlet part of the cyclone separation cylinder still contains dust with smaller particle sizes, which is not convenient to use. Therefore, we propose a dust collection device for boron carbide production to solve the above existing problems. Content of the Utility Model

[0026] Embodiment 1:

[0027] Please refer to Figures 1 - 4, A dust collection device for boron carbide production, comprising a cyclone separation cylinder body 1, a bracket is fixedly installed on the outer side of the cyclone separation cylinder body 1, an air inlet part 101, an air outlet part 102 and a blanking port part 103 are arranged on the cyclone separation cylinder body 1, a dust discharge valve is fixedly installed at the bottom of the blanking port part 103, and a microfiltration mechanism 2 is arranged on the air outlet part 102;

[0028] The microfiltration mechanism 2 includes a housing 3 fixedly installed at the top of the air outlet part 102, an upper cover plate 4 and a driving motor 5 are fixedly installed at the top of the housing 3, and an air outlet pipe 6 is fixedly installed on one side of the top of the upper cover plate 4. An upper sealing plate 7 and a lower sealing plate 8 are fixedly installed inside the housing 3. A negative pressure chamber is formed between the upper sealing plate 7 and the upper cover plate 4, and the negative pressure chamber is communicated with the inside of the air outlet pipe 6. The upper sealing plate 7 and the lower sealing plate 8 are fixedly installed at the central position through a connecting pipe 9, and the bottom of the connecting pipe 9 penetrates through the central position of the bottom of the lower sealing plate 8. A rotating pipe 10 is rotatably connected inside the connecting pipe 9 through a bearing and a sealing ring. The bottom of the rotating pipe 10 extends to the inside of the air outlet part 102 through the bottom of the lower sealing plate 8. The driving shaft at the bottom of the driving motor 5 sequentially penetrates through the central positions of the upper cover plate 4 and the upper sealing plate 7 and is fixedly installed with the top of the rotating pipe 10;

[0029] Isolation plates 11 are also fixedly connected to both sides of the connecting pipe 9 between the upper sealing plate 7 and the lower sealing plate 8. Openings 901 are provided on both outer walls of the connecting pipe 9 on both sides of the isolation plates 11. An opening 1001 is provided on the rotating pipe 10 corresponding to one of the openings 901. A plurality of card holes 701 are provided on the upper sealing plate 7, and filter cartridges 12 are fixedly clamped at the bottoms of the plurality of card holes 701. The inside of the filter cartridge 12 is communicated with the inside of the negative pressure chamber through the card holes 701. A plurality of dust cleaning openings are equidistantly provided on the outer wall of the housing 3, and sealing plates 301 are fixedly installed outside the dust cleaning openings.

[0030] The working principle of this boron carbide production dust collection device is as follows:

[0031] First, connect the air supply pipe through the air inlet part 101 of the cyclone separation cylinder body 1, so that the dust-containing air flow enters the inside of the cyclone separation cylinder body 1 through the air inlet part 101. At this time, affected by the shape structure of the cyclone separation cylinder body 1, the dust-containing air flow moves spirally downward inside the cyclone separation cylinder body 1, so that the dust particles with larger particle sizes precipitate at the bottom of the blanking port part 103, which is convenient for later discharge through the dust discharge valve. The finer particles rise with the upward air flow in the central area inside the cyclone separation cylinder body 1 and rise to the air outlet part 102;

[0032] At this time, the fine particles with smaller particle sizes enter the interior of the rotating tube 10 of the microfiltration mechanism 2 along with the rising air flow, and enter the inner side of the corresponding outer casing 3 through the second opening 1001 and the corresponding first opening 901. At this time, the fine particles with smaller particle sizes are blocked by a plurality of filter cartridges 12, and the clean air flow passes through the filter cartridges 12 and enters the negative pressure chamber through the card holes 701, and finally is discharged through the air outlet pipe 6.

[0033] When it is necessary to clean the plurality of filter cartridges 12 on this side inside the outer casing 3, only need to start the drive motor 5 to drive the rotation of the rotating tube 10, align the second opening 1001 with the corresponding first opening 901 on the other side inside the outer casing 3. At this time, the air flow mixed with particles can be filtered on the other side inside the outer casing 3. The specific filtering principle is as described above. During this period, the sealing plate 301 corresponding to the just-filtered side can be opened to expose the plurality of filter cartridges 12 installed inside the outer casing 3 for cleaning operations. The whole process does not require shutdown operations, which is more convenient to use.

[0034] Embodiment 2:

[0035] In view of the above Embodiment 1, a further description is made. Refer to Figure 4 The outer wall diameter of the filter cartridge 12 is smaller than the outer wall diameter of the rotating tube 10.

[0036] By making the outer wall diameter of the filter cartridge 12 smaller than the outer wall diameter of the rotating tube 10, it is avoided that there is excessive congestion during installation and installation interference occurs. The isolation plates 11 fixedly connected to both sides of the connecting pipe 9 between the upper sealing plate 7 and the lower sealing plate 8 can divide the filtered chamber inside the outer casing 3 into two parts, which is convenient for the second opening 1001 of the rotating tube 10 to rotate and switch without affecting the dust cleaning operation on the other side.

[0037] The above is only the preferred specific implementation manner of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
