Description
Technical field
The present invention relates to a kind of weldering fume and dust devices, net more particularly to a kind of efficient flue dust of the servo-actuated lower pump drainage of high negative pressure
Change filter device and smoke abatement technique, belongs to weld fumes dust removal by filtration technical field.
Background technique
Welding is industrially to make a kind of material basic technology interconnected, is widely used in civil engineering, machinery and material
Manufacture field, with the continuous propulsion of China's industrialization degree, welding technique has broad application prospects.
However, the adverse factor generated during weld job but constrains the application and development of welding technique.It welded
Adverse factor in journey can be divided into welding fume, toxic gas, electromagnetic field of high frequency, ray, arc radiation and noise etc..Wherein,
Welding fume is the tiny particles content that welding material is formed under high temperature action with electrode welding process.According to statistics, the whole world disappears every year
Welding material of metal in the welding material of metal of consumption there are about 0.5% is changed into weld fumes.
Sensu lato weld fumes is a kind of mixture of complexity, can be divided into solid fraction and gas phase portion, solid phase portion
Subpackage contains Fe2O3、MnO2, the metal particulates such as Sn, Pb, gas phase portion includes the gases such as NOx, CO and HF；Welding in the narrow sense
Flue dust refers to the fine solid particle object formed in the welding process, and usual butt welding cigarette, which is collected and purifies, to be referred in the narrow sense
Weld fumes.In restricted clearance or confined space, the lesser weld fumes of partial size suspends in air, because being largely gathered in work
In industry space, voluntarily it cannot settle or eliminate, therefore the health and construction environment of welding operator are caused greatly
Harm.Existing research discovery, particle of the partial size less than 10 μm can enter trachea and bronchus, and particle less than 2 μm can be with
Inside is entered the respiratory system, and is not easy to be excreted.Most weld fumes can enter human respiratory,
It is up to 50% or more in the deposition of lung, and lung's dust deposition can excessively cause the lesion of respiratory system, in pneumoconiosis, manganese
The diseases such as poison, metal fever, pulmonary emphysema, chronic bronchitis or even lung cancer.According to investigations, the personnel for being engaged in welding suffer from and exhale
The ratio for inhaling tract disease is much higher than other industry practitioner, and it is about high by 30% to suffer from the Hazard ratio of lung cancer other crowds.
Weld fumes and dust, can also be other than it can damage to the health for being directly engaged in weld job personnel
As air-flow migrates in restricted clearance, threaten to other personnel of the operation in entire factory；And flue dust is in air-flow
Slow position aggregation is flowed, will also result in air quality deterioration and visibility in working space reduces, and to construction and produces peace
Hidden danger is brought entirely.
Currently, the main method using ventilation carries out weldering fume and dust, weld fumes particulate matter follows air-flow to transport in space
It is dynamic, flue dust is taken away by operation interval by reasonable air current composition, to reduce indoor dust concentration, improve air quality.Ventilation
Purification can be divided into gravity-flow ventilation purification and force ventilation purification two major classes, and structure is complicated, spatial volume is big at welding procedure scene, single
It is pure to be difficult to meet the requirements by gravity-flow ventilation purification, therefore force ventilation purification style is mainly used in working shop of enterprise.Although city
There is more mechanical ventilator on face, but all there are several disadvantages, as dust removing effects are undesirable, purification is not up to standard, equipment is huge
Take up space greatly, dedusting cannot be pinpointed, dedusting cannot be servo-actuated etc..

Stating source to inhale the negative pressure that range is formed is -5KPa ~ -18KPa.
9. a kind of smoke abatement technique of the servo-actuated lower pump drainage of high negative pressure, which comprises the following steps:
1) using the efficient flue dust filtration equipment for clarifying of the servo-actuated lower pump drainage of high negative pressure described in claim 1 ~ 8, by source absorbing smoke dust
Capture device is mounted on welding robot weldering arm or welding machine welding gun；
2) by base material to be welded carry out Butt Assembling, adjust source absorbing smoke dust capture device installation site, make its with to welding line lead
It is 20mm ~ 60mm that vertical line, which keeps vertical range, and makes the smoke absorbing end of source absorbing smoke dust capture device apart from base material 5mm ~ 10mm to be welded；
3) before implementing butt welding using metal arc welding or non-melt pole electrical arc weldering, first vacuum pump is opened, then open weldering
It connects and is used to only carry out so that range formation negative pressure is inhaled in source according to the evacuated pressure of setting value adjusting vacuum pump with protective gas
Protective gas of the flue dust collecting without destroying the be supplied to working space of welding process；
4) implement butt welding, the flue dust generated during weld job is collected by source absorbing smoke dust capture device, and is discharged into suction
Dirt channel；
5) by filtering dust collect plant to the flue dust for being discharged into dust absorption passage be filtered and collect filtering after dust, then export
Filtering smoke；Filtering smoke is cooled down by circulating cooling system, then exports the filtering smoke cooled down,
The filtering smoke cooled down is drained into the exhaust system of peripheral hardware finally by vacuum pump.
10. the smoke abatement technique of the servo-actuated lower pump drainage of high negative pressure according to claim 9, it is characterised in that: in the step 3)
Implementation butt welding before be to weld preceding 5-10s.
