The utility model relates to a concentrating ventilator, which comprises a shell, which is a cylinder-shaped case with front and rear permeability. The shell is internally fixed with a concentrating ventilation device. The concentrating ventilation device comprises an outer gallbladder, which is a cylinder-shaped case with front and rear permeability. The outer gallbladder is located in the shell, and a connecting tube is fixed and connected with the outer shell, and a high-pressure air pipe is closed and connected with a valve. The inside of the door and outer gallbladder is provided with inner gallbladder, which is a cylindrical shape with front and rear permeability. The space between the outer gallbladder and the inner gallbladder is a ventilation gallery. The ventilation gallery and the connecting pipe are closed and connected. The back baffle is closed and fixed between the back end of the outer gallbladder and the back end of the inner gallbladder, and the back baffle is circular. The back baffle is located at the back end of the ventilation gallbladder, and the front end of the outer gallbladder is closed and fixed with front baffle, The front baffle is located at the front end of the ventilation bin, and the front baffle is provided with a plurality of ventilation holes with front and rear permeability. The outer edge of the front baffle is inclined forward. The ventilation holes are evenly distributed with equal spacing.
【技术实现步骤摘要】
聚能通风器
本专利技术涉及一种矿井通风安全装置,尤其涉及一种聚能通风器。
技术介绍
采煤工作面回风隅角因现场限制,无法实现良好的通风,导致有害气体在回风隅角处积聚,造成有毒有害气体浓度上升、氧气含量下降,对现场施工人员安全不利,现场存在一定的安全隐患。为了解决工作面回风隅角有毒有害气体积聚,氧气含量低的问题,通常使用高压风管直接向回风隅角供风,但因其供风范围小、风压冲击力较大、噪声大等问题,对工作面施工人员在回风隅角施工中造成了不小的影响。
