AI Technical Summary

Technical Problem

The existing coal mining and ventilation equipment will bring out the internal dust during the negative pressure ventilation process, causing the dust to spread in the air, affecting the environment, and lacking dust collection devices.

Method used

A ventilation device for coal mining is designed, including a ventilation device and a transmission device. The ventilation device includes a negative pressure fan and a collection bag. The wind power generated by the negative pressure fan ensures that the dust is located at the top of the collection bag and the collection bag is tied from the middle to complete the collection bag.

Benefits of technology

By setting up a collection device, ventilation is used to prevent dust from spreading in the air, improving environmental quality and improving the use effect of the equipment.

Abstract

The utility model relates to the technical field of ventilation equipment for coal mining, and discloses ventilation equipment for coal mining, which comprises a working table, a limiting vertical plate is arranged on the surface of the working table, a transmission device is arranged in the working table, a ventilation device is arranged at the top of the limiting vertical plate, and the ventilation device is arranged in the working table. The ventilation device comprises a connecting frame, a bearing seat, a butt joint strip, a butt joint piece, a fan barrel, an inner connecting rod, a negative pressure fan, a collecting bag, a butt joint hollow seat, an inserting column and an inner supporting transverse plate. According to the ventilation equipment for coal mining, the ventilation device is arranged, wind power generated by a negative pressure fan can ensure that dust is located on the uppermost portion of a collection bag and cannot be scattered, then a user can tie the collection bag from the middle while the negative pressure fan is started, dust collection is completed, and a collection device is arranged in the device, so that the dust collection efficiency is improved. Dust is prevented from spreading in the air to influence the environment during ventilation, and the use effect is good.
