Technical Field

[0001] The utility model relates to the technical field of concrete processing, in particular to a dust collecting device for a silo of a concrete mixing station. Background Art

[0002] During the production process of a concrete mixing plant, the top of the silo is the main source of dust generation and diffusion. Due to the crushing, screening, mixing and other process operations of concrete raw materials, a large amount of dust will be generated. This dust not only seriously pollutes the production environment and affects the health of operators, but also may cause increased wear of equipment and reduce production efficiency. Therefore, effective control of dust on the top of the silo of a concrete mixing plant has become an urgent problem to be solved.

[0003] Traditional dust removal methods mainly include wet dust removal and dry dust removal. Although wet dust removal can effectively capture dust, the treated wastewater needs to be treated again, which increases the treatment cost. Dry dust removal, such as bag dust collector, has a simple treatment process, but the bags are prone to clogging and damage after long-term operation, and need to be replaced regularly, with high maintenance costs.

[0004] Therefore, in view of the current situation and existing problems of dust control on the top of the silo of the concrete mixing station, it is necessary to design a new type of dust removal device. Utility Model Content

[0005] In order to solve the above-mentioned problems, the utility model designs a dust collecting device for a silo of a concrete mixing station.

When the filter 11 needs to be self-cleaned, the filter 11 drives the connecting plate 12 and the support rod 15 to rotate at high speed through the round rod 10. When the filter 11 rotates at high speed, centrifugal force is generated to shake off the dust on the outer wall, and at the same time, the metal ball 14 is caused to rotate in the filter 11, and the dust attached to the outer wall of the filter 11 is further cleaned by hitting and knocking the inner wall of the filter 11.

The specific connection and control sequence should refer to the following working principle, and the electrical connection is completed in the working order of each electrical component. The detailed connection means are well-known technologies in this field and will not be explained in the electrical control.

[0028] A specific application of this embodiment is:

[0029] When in use, the device is used in conjunction with a dry dust collector. The dust removal fan transports the dust into the cylinder 1 through the air inlet pipe 2, and the dust enters the filter screen 11 after being filtered through the outer wall of the filter screen 11, and is discharged through the metal mesh cover 13, the support rod 15 and the exhaust pipe 8. The filtered dust adheres to the outer wall of the filter screen 11. When the filter screen 11 needs to be self-cleaned, the round rod 10 causes the filter screen 11 to drive the connecting plate 12 and the support rod 15 to rotate at high speed. When the filter screen 11 rotates at high speed, centrifugal force is generated to throw off the dust on the outer wall, and at the same time, the metal ball 14 is caused to rotate in the filter screen 11, and by hitting and knocking the inner wall of the filter screen 11, the dust attached to the outer wall of the filter screen 11 is further cleaned, thereby improving the self-cleaning effect.
