Abstract
The utility model provides a suction and filter pump for welding gas dust, which uses the negative pressure formed by ejecting compressed air as a power source. The liquid is blown out with the compressed air so as to form gas fog. The extracted welding fume and the gas-liquid fog are mixed together, and then the liquid and the gas are separated by a centrifugal separator. The clean air is released back to a workshop. The liquid with fume particles can be recycled after the fume particles are removed by a fume particle separating system. The utility model has the characteristics of energy consumption saving, long cleaning period, favorable dust filtrating effect, low use cost, convenient maintenance and long service life.
Description
The utility model patent provides a kind of well behaved weld fumes suction strainer pump.The negative pressure that it produces during with blast injection is as the power of suction weld fumes, and forms the liquid mist at the exit of compressed-air atomizer atomizing of liquids.Contain the air stream of liquid composition and the flue gas stream that sucks, after in injecting tube, fully mixing,, liquid, gas are separated, between the air discharging carriage return of cleaning by centrifugal gas, separator.The liquid that contains smokeshade through processing such as precipitation, filtration, absorption, after the filtering smokeshade, recycles.
Once proposing with compressed air in the patent document of smoking-collecting type gas protective welding gun (ZL 97 2 34279.6) is the weld fumes suction strainer pump of power.This suction strainer pump adopts the mode filtering flue dust of cloth bag filtration.Though it has the advantage that volume is little, in light weight, noise is low.Efficiency of dust filtration is not high, do not grow the shortcoming that just will clear up or change bag dust filter service time but exist in actual use.
The purpose of this utility model is that a kind of long service life, the filter weld fumes suction strainer pump that dirt is effective, use cost is cheap, easy to maintenance are provided.
The utility model be a kind of be power with compressed air, press the weld fumes suction strainer pump that jet produces the negative pressure principle design, it is formed by the container combination of compressed air electromagnetic valve, pressure regulator valve, jet absorption type negative pressure pump, centrifugal gas, separator, smokeshade separator, liquid circulating pipe road, liquid make-up.From the compressed air of workshop pipeline, at first pass through compressed air electromagnetic valve, this magnetic valve is opened simultaneously with the electric welding striking, closes simultaneously or time-delay closing with arc extinguishing.Compressed air behind solenoid control and pressure regulator valve steady pressure by being arranged on the compressed-air atomizer on the pressure regulator valve, sprays to the conical entrance of injecting tube.According to Bai Nuli equation principle, the inner chamber of the negative pressure pump housing forms negative pressure, thereby takes weld fumes away.The utility model patent is characterized in that: the exit at compressed-air atomizer is provided with liquid outlet.Liquid from the circulating line sprays with compressed air, and is nebulized by being dispelled.The welding flue gas of vaporific liquid, gas mixed flow and suction fully mixes in the runner of injecting tube.The aerosol that contains smokeshade after the injecting tube ejection, flows into centrifugal gas, separator that the air-flow generation is rotatablely moved.Under action of centrifugal force, on the heavier outer wall of dust-laden liquid, flow back to the smokeshade separator downwards attached to eddy channel, behind the removing grit,, flow back to liquid outlet through circulating line, reuse.According to the physical characteristic of smokeshade, the smokeshade separator can have multiple versions such as precipitating type, filtering type, magnetic adsorption type.In order to compensate the evaporating loss of liquid composition, liquid level is stable in the maintenance sedimentation basin, can add the container of liquid make-up.In order to reduce pneumatic noise, can be provided with a silencer cover.
Because above feature makes weld fumes suction strainer pump described in the utility model reach long service life length, the filter purpose that dirt is effective, use cost is cheap, easy to maintenance.
The utility model is described in further detail below in conjunction with drawings and Examples.
Figure one is that weld fumes suction strainer pump of the present utility model adopts swirl vane formula whizzer, adopts the profile construction figure of a kind of embodiment of the combined type smokeshade separator that refilters after elder generation's precipitation and the magnetic absorption.
