Smoke evacuation apparatus during welding

Abstract

The invention discloses a smoke evacuation apparatus during welding, including: a smoke evacuation pipeline (1) with one end closed and the other end connected to a blower fan, and the bottom surface of the smoke evacuation pipeline assumes a rectangular shape, and the upper surface of the smoke evacuation pipeline assumes an arc shape, and the bottom surface of the smoke evacuation pipeline is provided with a plurality of ventilating openings which are evenly distributed, and the ventilating openings are communicated with a diversion channel, wherein the diversion channel includes: a straight tube segment (3) which is communicated with the ventilating openings, a condenser tube segment (4) which is arranged at the rear end of the straight tube segment and a taper-shaped air inlet (5) which is fixedly connected to the rear end of the condenser tube. The condenser tube assumes a shrinking shape of the diameter of the straight tube segment and is in arc transit connection with the straight tube segment and the taper-shaped air inlet, and the inner wall of the condenser tube segment is wound by a plastic flexible tube (6) which is provided with a condensing agent. The invention has the beneficial effects that smoke is evacuated,the taper-shaped air inlet is aligned with a welding source, and the flue gas is subject to condensing via the condenser tube segment and accelerating via the straight tube segment, large-granule impurities in the flue gas are filtered with a filtering net, and the flue gas is sent to other apparatuses for storage or purification by the blower fan. The smoke evacuation apparatus during welding is fast and convenient to handle.

Description

technical field [0001] The invention relates to a smoke exhaust device, in particular to a welding smoke exhaust device. Background technique [0002] Capacitors, usually referred to as capacitance for their ability to hold charges, are denoted by the letter C. Definition 1: A capacitor, as the name implies, is a 'charged container', a device that holds charges. English name: capacitor. Capacitors are one of the electronic components widely used in electronic equipment, and are widely used in DC blocking, coupling, bypass, filtering, tuning loops, energy conversion, control, etc. in circuits. Definition 2: Capacitor, any two conductors (including wires) that are insulated from each other and are very close to each other form a capacitor. Capacitors have to go through three steps of energization, welding, and board arrangement in the production process. Among them, welding will generate a lot of smoke, pollute the working environment, and adversely affect the health of ope...
