Problems solved by technology

[0003] 1. Complicated installation and customized design cannot meet more application scenarios
[0004] 2. A layer of air curtain separates the working area from the worker's operating area, but the protection is limited, and some dust still enters the worker's operating area
[0005] 3. The angle of the air curtain is fixed and cannot be fine-tuned according to the specific scene

Embodiment Construction

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0023] Such as Figure 1 to Figure 3 As shown, a modular air curtain device for fully mechanized excavation includes an air curtain module 2, a pipeline module 3 and a fan 4. One end of the pipeline module 3 is connected to the air curtain module 2, and the other end is connected to the fan 4. The model of the fan 4 is based on The specific working conditions are selected. The fan 4 is used to generate high-pressure gas. The air curtain module 2 is installed outside the cockpit of the roadheader 1, and the fan 4 is installed on the chassis trolley located at the rear end of the roadheader 1.

[0024] Such as Figure 4 and Figure 5 As shown, the air curtain module 2 includes a plurality of air curtain devices, and the multiple air curtain devices have the same structure, and all include an air curtain main body and a constant velocity wedge ...

Abstract

The invention discloses a modular fully mechanized excavation face air curtain device and a using method, and belongs to the technical field of mining engineering ventilation and dust removal. The device comprise an air curtain module, a pipeline module and a fan. One end of the pipeline module is connected with the air curtain module, and the other end of the pipeline module is connected with thefan. The air curtain device adopts the modular design, the installation position and the installation number can be adjusted according to specific requirements, the angle of the air curtain device can be adjusted, the angle of an air curtain can be adjusted, and the more scene requirements are. A worker operation area is separated again to form a second barrier, so that workers are protected.

Description

technical field [0001] The invention belongs to the technical field of mining engineering ventilation and dust removal, and in particular relates to a modular air curtain device for fully mechanized excavation face and a use method thereof. Background technique [0002] The coal mine excavation surface in our country is seriously damaged by dust, and the coal mine comprehensive roadheader is widely used in the coal mine excavation roadway, which produces a lot of dust and noise, which deteriorates the working environment. At home and abroad, a lot of research has been done on the problem of dust prevention in fully mechanized excavation in coal mines. In recent years, a lot of research has been done on the use of air curtains for dust control, dust isolation, dust suppression and dust removal. The air curtain integrated dust removal system for the fully mechanized excavation face researched by Professor Li Yucheng mainly adopts the conventional hybrid ventilation method, th...
