Automatic collecting device for combustion waste gas generation area and provided with swing rod

Abstract

The invention provides an automatic collecting device for a combustion waste gas generation area and provided with a swing rod. The device comprises a device main body; the front side end of a handheld body is provided with a separation cavity, a welding gun pipe is connected to the front end of the separation cavity, waste gas collection pipes are connected to the two sides of the welding gun pipe through clamping rings, the rear ends of the waste gas collection pipes penetrate into the separation cavity, and the lower end of a filter cylinder is hermetically connected to a waste gas outlet connection opening through threads and is in inclined contact with the upper end of the handheld body. A trigger switch is pulled to drive the swinging rod to move backwards, so that the conical frontend of a U-shaped structure of the swinging rod is respectively disconnected from a sealing vertical plate B, a left lower chamber communicates with a right lower chamber, argon in the right lower chamber can flow into the left lower chamber, the argon enters the welding gun tube through a through hole in the lower end of a sealing vertical plate A, and a right upper chamber communicates with a left upper chamber; and the exhaust gas flows through the filter cylinder and is collected in a vacuum bottle or an exhaust device by using a vacuum or an exhaust pipe connected with an external connecting pipe.

Description

technical field [0001] The invention belongs to the technical field of waste gas collection, and more specifically relates to an automatic collection device for combustion waste gas generation areas equipped with swing rods. Background technique [0002] Exhaust gas collection device refers to a set of gas collection equipment used for environmental protection treatment equipment. Its main purpose is to introduce harmful gas or dust generated by the reaction into the purification system, and at the same time prevent it from spreading to the production workshop and the atmosphere, causing pollution. [0003] For example, in the patent with the application number: CN201820758907.8, an automatic exhaust gas collection device is disclosed. The automatic exhaust gas collection device includes an exhaust gas collection cover, an exhaust pipe and a bracket, and the exhaust pipe is connected to the top of the exhaust gas collection cover. , the bracket is provided with a fixed shaft...
