Abstract

The utility model discloses a welding fume processing device, which comprises arc light sensors, a fume air inlet, a driving device and a fume pipeline. The fume air inlet is connected with the fume pipeline; a plurality of the arc light sensors are arranged on the edge of the fume air inlet; and the arc light sensors are connected with the driving device through lines. Deviation signals are produced according to whether each arc light sensor is welded with an air inlet of a fume catch device and real-time welding point deviation condition. After the deviation signals are processed by amplification, filtering and shaping, the air inlet is judged whether or not to deviate from welding beads. Attitudes of the air inlet is adjusted by a welding fume welding bead tracking and driving device to reach the purpose of tracking welding positions in real-time manner. The welding fume processing device has small investment and low use cost, lowers labor intensity and increases working efficiency.

Description

A kind of weld fumes treating apparatus

Technical field:

The utility model relates to environmental protection equipment, is specifically related to a kind of weld fumes treating apparatus.

Background technology:

Can produce a large amount of flue dust and flue gas in the welding process, its Main Ingredients and Appearance is metal oxides such as iron and manganese, particle mean size is 0.1um-1.25um, can directly be sucked lung by human body, and contain a large amount of poisonous and harmful substances in the weld fumes, the long-term weld fumes that sucks is very big to human health damage.

The operating mode that factories and miness large-scale workpiece, welding position are fixing, fusion length is long adopts the air-breathing welding gun of band flue dust seizure, air-breathing welding mask, this soot processing device that the band flue dust is caught usually, strengthened the weight of instrument, increase working strength of workers, reduced operating efficiency; Large-scale top inhale cover or workplace etc. mode, need big air-breathing air quantity, investment is big, use cost is higher.

Summary of the invention:

The purpose of this utility model is to provide a kind of weld fumes treating apparatus.And can not increase working strength of workers, increase work efficiency; Invest little, use cost is low.

The purpose of this utility model is achieved like this, this weld fumes treating apparatus, comprise arc photosensor, flue dust air inlet, drive unit, fume ducts, the flue dust air inlet is connected with fume ducts, flue dust air inlet edge is provided with a plurality of arc photosensors, and arc photosensor is connected with drive unit by circuit.

Described a plurality of arc photosensor is positioned at same plane, and the center line of the center line of each arc photosensor and air inlet meets at a bit in the space jointly.

Because flue dust air inlet edge is provided with a plurality of arc photosensors, arc photosensor is connected with drive unit by circuit, according to its deviation signal of producing of air inlet and the pad deviation situation in real time of weld fumes trap setting whether, after deviation signal process amplification filtering shaping processing, judge by system processor whether air inlet departs from weld seam, adjust the attitude of air inlet by weld fumes weld joint tracking drive unit, reach the real-time tracking welding position, thereby realize following the tracks of weld fumes, guarantee that air inlet is fixed with real-time weld locations relative position in the welding process, thereby realize the purpose of the automatic trace trap of weld fumes.

A plurality of arc photosensors are positioned at same plane, and the center line of the center line of each arc photosensor and air inlet meets at a bit in the space jointly, realize that the automatic trace trap of weld fumes is more accurate.

In sum, owing to the mode of real-time tracking welding position, greatly reduce the requirement of the intake of weld fumes capture system, energy demand when having reduced work, the automatic trace trap weld fumes of system is respond well, stable and reliable operation, practical, invest little, use cost is low; Also improved the automation and the intelligent degree of system, working strength of workers is low, has improved operating efficiency, has reduced system cost.

Fig. 1 is the structural representation of weld fumes treating apparatus.

Fig. 2 is the welding arc photosensor structural representation of weld fumes treating apparatus.

Fig. 3 is a weld fumes treating apparatus arc photosensor circuit block diagram.

The specific embodiment:

Referring to Fig. 1, Fig. 2, Fig. 3,1 workpiece, 2 arc photosensors, 3 flue dust air inlets, 4 drive units, 5 and 6 are that weld fumes pipeline, 7 smoke treatment devices, 8 are welding gun, 9 is real-time pad, and 10 sensor front end face shields, 11 light damping plates, 12 filter plates, 13 are that infrared sensor or Ultraviolet sensor or vision sensor, 14 are holding wire for shell, 15.

This weld fumes treating apparatus, comprise arc photosensor 2, flue dust air inlet 3, drive unit 4, fume ducts 5,6, flue dust air inlet 3 is connected with fume ducts 5,6, flue dust air inlet 3 edges are provided with a plurality of arc photosensors 2, arc photosensor 2 is connected with drive unit 4 by circuit 15, and drive unit 4 is made up of system processor and electromechanical control equipment commonly used.

According to its deviation signal of producing of air inlet 3 and the pad 9 deviation situations in real time of weld fumes trap setting whether, after deviation signal process amplification filtering shaping processing, judge by system processor whether air inlet 3 departs from pad 9, adjust the attitude of air inlet 3 by following the tracks of drive unit 4, reach real-time tracking pad 9, thereby realize following the tracks of weld fumes, guarantee that air inlet is fixed with real-time weld locations relative position in the welding process, thereby realize the purpose of the automatic trace trap of weld fumes.

Described a plurality of arc photosensor 2 is positioned at same plane, and arc photosensor 2 used numbers are more than or equal to 3, and the center line of the center line of each arc photosensor 2 and air inlet 3 meets at a bit in the space jointly.Each sensor 2 output signal was close when air inlet 3 attitudes faced pad 9; Utilize the arc light of welding itself, welding arc is the center with pad 9, optical frequency to the various wavelength of external radiation, when deviation takes place in the attitude of air inlet 3 and pad 9 positions, each sensor 2 output signal changes, and system processor is according to the signal of each sensor 2, and the control weld fumes is followed the tracks of the attitude that drive unit 4 is adjusted air inlet 3, make air inlet 3 with optimum posture over against pad 9 positions, reach that weld fumes is as much as possible to be captured.

Arc photosensor need increase light damping plate and filter plate, and light damping plate is used to reduce the intensity of arc light; The light that filter plate is used to limit specific wavelength passes through.When selecting, arc photosensor need avoid the influence of visible light.Arc photosensor can be used the selection according to filter plate, corresponding selection Ultraviolet sensor or infrared sensor, also available vision sensor.
