Description

Technical Field

[0001] The utility model relates to the technical field of coal mining, in particular to a ventilation and dust prevention device in a coal mine. Background Art

[0002] The coal mine dust prevention and ventilation device is a device that provides fresh air underground in the mine. It consists of ventilation ducts and pressure-dividing fans. It is mainly installed in locations with good air circulation. It has good practical effects and low power consumption. It is widely used in various mine mining fields.

[0003] Coal mines are areas where humans extract coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, the coal is usually mined by tunneling underground, which is an underground coal mine. When the coal seam is very close to the surface, the coal is usually mined directly by removing the surface soil layer, which is an open-pit coal mine. The vast majority of coal mines in my country are underground coal mines. Coal mines encompass a large area both above and below the ground, as well as related facilities.

[0004] The existing patent publication number is CN214697906U, which discloses a coal mine ventilation and dust prevention device, including a dust removal box body, an air inlet is opened on one side of the dust removal box body, and the air inlet is connected with a first dust removal plate through the connection, and a preliminary dust removal duct is opened inside the dust removal box body, and the preliminary dust removal duct is fixedly connected with a plurality of dust removal air ducts through a plurality of first connecting holes opened on an outer wall of one side thereof, the dust removal box body is connected with a second dust removal plate through a positioning groove opened on one side of its top, a dust removal water trough is opened on the top of the dust removal box body, and a circulation box body is fixedly connected with the other side of the dust removal box, and a circulation chamber is opened inside the circulation box body, and the dust removal water trough is fixedly connected with the circulation chamber through a connecting groove opened on the bottom of one side thereof, and the circulation chamber is connected with a third dust removal plate through the connection. The utility model can filter and dust-proof the air multiple times, and the water used to filter the air can be filtered and recycled inside the device, which is convenient and practical.

[0005] Existing ventilation and dust control devices in coal mines achieve dust control by filtering dust with dust removal panels. However, long-term use can lead to excessive dust accumulation on the panels, requiring workers to clean them. This process is time-consuming and labor-intensive, and the excessive amount of dust collected during cleaning can be harmful to workers' health. Therefore, we propose a ventilation and dust control device for coal mines to address these issues. Utility Model Content

[0006] The purpose of this section is to summarize some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and in the abstract and title of the present invention to avoid obscuring the purpose of this section, the abstract and the title of the utility model, and such simplifications or omissions shall not be used to limit the scope of the present invention.

[0007] Therefore, the purpose of the present invention is to provide a ventilation and dust prevention device for underground coal mines, which can solve the problem that the existing ventilation and dust prevention devices for underground coal mines achieve the dust prevention effect by filtering dust through dust removal plates, but long-term use will cause excessive dust accumulation on the dust prevention plates, requiring workers to clean their surfaces. This process is time-consuming and labor-intensive, and the excessive amount of dust when cleaning will affect the health of the workers.

[0008] In order to solve the above technical problems, the utility model provides a ventilation and dust prevention device for underground coal mines, which adopts the following technical solution: it includes a box body, and a first dustproof plate and a second dustproof plate are fixedly installed on both sides of the box body, and support frames are fixedly installed on the left side and inside of the box body.
