Embodiment Construction

[0015] For better understanding and implementation, a mobile exhaust hood of the present invention will be described in detail below in conjunction with the accompanying drawings, including a movable exhaust hood 1 located above the source of harmful substances, and the front of the movable exhaust hood is provided with a side-by-side door 3. It is convenient for routine operation of the internal equipment. The lower part of the movable exhaust hood is equipped with a roller 2, which is located on the guide rail 4, driven by a motor 5, and a limiter 6 is set to limit the position to ensure safe use. The exhaust hood is fixed 7 A sealing brush 8 is set at the junction with the movable exhaust hood 1 to reduce air leakage, and the outlet of the fixed exhaust hood 7 is fixedly connected with one end of the exhaust circular pipe, and the exhaust circular pipe is equipped with a valve to control the exhaust volume.

[0016] The invention improves the disadvantage that the local exh...

Abstract

The invention provides a movable exhaust hood which comprises a fixed exhaust hood. The fixed exhaust hood is connected with the movable exhaust hood, and rolling wheels are installed at the lower portion of the movable exhaust hood and located on guide rails. A motor is arranged on the movable exhaust hood, and limiters are arranged on the guide rails. A sealing brush is arranged at the position where the movable exhaust hood is combined with the fixed exhaust hood. The movable exhaust hood is provided with an oppositely-opening door. The shortcoming that the local exhaust hood is largely influenced by indoor air flows and close to a harmful pollution source is overcome, the movable exhaust hood is fixedly installed above or around a device, the defects of material adding or maintenance are overcome, small air exhausting amount is achieved, the noxious substance control effect is good, and the movable exhaust hood is not influenced by environmental air flows and is convenient to operate and high in automation degree.

Description

technical field [0001] The invention belongs to the field of metallurgical machinery, in particular to a mobile exhaust hood. Background technique [0002] At present, the measures for controlling harmful substances in workshops in industrial ventilation are usually to set up local exhaust hoods at the places where pollutants occur to capture them, so as to prevent them from escaping into the factory to pollute the environment and affect the health of workers. The local exhaust hood has the following disadvantages. It is greatly affected by the indoor airflow and must be close to harmful pollution sources, otherwise the air leakage rate is high and the exhaust volume is small; fixed installation above or around the equipment is not conducive to adding materials or maintenance. Contents of the invention [0003] The invention provides a movable exhaust hood, which solves the disadvantages of high air leakage rate and inconvenient equipment movement in the local exhaust hood...
