Technical field
The utility model relates to a kind of auxiliary welding equipment, especially a kind of device for welding flue gas ash removal.
Background technique
Welding personnel is mostly outdoor work, without any safeguard procedures, especially require welding structure intensity requirement it is higher, weldering
Connecing the welding rod used is J506 basic electrode, includes a large amount of silicon, silicate, manganese, chromium, fluoride in the flue dust that electric welding generates
And other metal oxides, stimulation can be generated to respiratory tract, the people of breathing is made not feel good.Tobacco poisoning can be welded when serious.
Heavy metal particle has microprecipitation in sucking lung, and long-time weld job, sucking have run up to a certain amount, and be easy to get weldering
The weld fumes that work pneumoconiosis, welder's pneumoconiosis there is no specific treatment measure at present, therefore need to be inherently eliminated operation field.
Electric welding field scene is mainly with gravity-flow ventilation and blower forced ventilation two major classes at present: gravity-flow ventilation because by weather and
Site work environment influences the flue dust that ventilation effect is poor, welding is caused to generate and floats up soldered operating personnel's via intranasal application suction
Entering lung leads to the generation of pneumoconiosis.Blower forced ventilation compares effect of natural ventilation preferably but has following drawback: 1. wind
The blowing force welding quality that machine generates has a significant impact, welding rod generates blow, electric arc shakiness, molten iron splash, molten bath is easy to produce
The defects of stomata, crackle；2. because flue gas that the influence blower of operation field and wind direction is blown away is easy to produce secondary fume caused by reflux
Gas pollution；3. assembling position generally will not be far apart from welding personnel, the vibration of blower rotation generation and noise are to human body
Injury greatly such as headache, dizziness, tinnitus, memory loss, eyesight reduce.

Fig. 1 is the structural schematic diagram of the utility model embodiment 1.
Fig. 2 is structural schematic diagram at peep hole in the utility model embodiment 2.
Fig. 3 is circuit diagram in the utility model embodiment 2.
Specific embodiment
The present invention will be further described with specific embodiment with reference to the accompanying drawings of the specification.
In embodiment 1, as shown in Figure 1, the utility model includes dust gathering arrester 4, aspiration channel 3, suction ventilator 2 and air-exhausting duct 1.
The dust gathering arrester 4 is the low wide and up narrow shell structure of bottom opening, positioned at the top of weld job point, bottom
Face is the square of 600mm*600mm, height 400mm.In dust gathering arrester 4 towards staff's one side there are peep hole 10,
And use glass capsulation.There are the welding position 120mm*200mm hole, welding position pitch-row dust excluding hood top 150mm for dust excluding hood two sides
Place, to facilitate weld job personnel to operate.
4 top of flue gas dust gathering arrester connects the aspiration channel 3 of DN133,1.2 meters of 3 standpipe height of aspiration channel, and air draught standpipe passes through
90 ° of elbows and 10 meters of long horizontal pipes are connected to 2 entrance of suction ventilator, and ring flange with M10*40, fix by totally 6 bolts.It inhales
The model L-092 of blower 2,5 power 4KW of its motor, flow 4080m3/h guarantee that the use at scene needs.Air-exhausting duct 1 with
With M10*40, totally 6 bolts connect the outlet of suction ventilator 2, and 1 DN133 of air-exhausting duct, 8 meters high, end connect short tube with 45 ° of elbows
0.5 meter, the vertical notch in outlet prevent rainwater from entering.
Fundamentally prevent the injury for flue gas butt welding staff's respiratory system that welding generates by the utility model,
The generation of welder's pneumoconiosis disease is effectively avoided, welding is to carry out in dust gathering arrester 4, weld the ultraviolet light generated, splash quilt
Dust gathering arrester 4 blocks, almost avoids light radiation and burn and scald, since the installation of suction ventilator 2 is avoided because making an uproar farther out (10 meters)
Sound greatly impacts staff's hearing.
In embodiment 2, the present embodiment main structure hereinafter only introduces the area of the present embodiment Yu embodiment 1 with embodiment 1
Other technical characteristic is not repeated with the same technique feature of embodiment 1.
As shown in Fig. 2, peep hole 10 is equipped with transparent glasses lens 11 and sunshade lens 8, wherein transparent mirror in the present embodiment
Piece 11 is fixed on peep hole 10, and 8 one side edge of sunshade lens and the edge of peep hole 10 are hinged, sunshade lens 8 it is another
Side is fixed with magnet 7, is respectively equipped with two electromagnet positioned at the two sides up and down of sunshade lens 8, i.e. No.1 electromagnet 6 and No. two
Electromagnet 9, the magnet 7 of one of electromagnet and eyeglass is attracting after two electromagnet are powered, another electromagnet and eyeglass magnetic
Iron 7 repels each other.
It further include ammeter in the present embodiment, the ammeter is undesirable mutual electromagnetic inductance formula, and ammeter is placed on welding gun
On electric wire, after starting welding, welding gun wiring harness after detecting electric current by ammeter, controls the energization of electromagnet, passes through electricity
The magnetic force of magnet controls sunshade lens 8, so that sunshade lens 8 is covered peep hole 10, hurts eye to prevent from being welded strong light；Welding finishes
Afterwards, welding gun electric wire powers off, and controls electromagnet by ammeter and changes current direction, i.e. change magnetic force direction, passes through electromagnet
Magneticaction opens sunshade lens 8, makes only to remain transparent glasses lens 11 in peep hole 10, so as to the feelings of clear view weldment
Condition.
As shown in figure 3, on the DC power supply of the circuit connection where electromagnet, including three branches, branch one include string
The amplifier and relay coil KA of connection, ammeter output terminate on the input terminal of amplifier, and the output of amplifier terminates at
On branch one.When soldered, welding gun wiring harness, ammeter generates faint induced current, into the input port of amplifier,
Biggish electric current is generated by the amplification of amplifier, so that branch one is powered, relay coil KA obtains electric；When not welding,
The power-off of welding gun electric wire, branch one power off therewith, relay coil KA power loss.Branch two includes the normally closed touching of relay being serially connected
Point KA-2 and relay normally open contact KA-4, branch three include the relay normally open contact KA-1 being connected in series and the normally closed touching of relay
Point KA-3.Two branch road normally opened contacts are opposite with the order of connection of normally-closed contact.Two electromagnet YA1, YA2 phases are simultaneously
Connection, both ends are located on branch two and branch three, and its tie point is located between the contact of each road two
Position.When relay coil KA power loss, two normally-closed contact KA-2, KA-3 closures, two normally opened contacts KA-1, KA-4 are disconnected
It opens, two electromagnet YA1, YA2 pass through two normally-closed contacts KA-2, KA-3 respectively and connect to power supply, and sunshade lens 8 are at this time
Opening state does not cover on peep hole 10, as shown in heavy line part in Fig. 2；After relay coil KA obtains electric, two often
Closed contact KA-2, KA-3 are disconnected, and two normally opened contact KA-1, KA-4 closures, two electromagnet YA1, YA2 pass through two often respectively
Contact KA-1, KA-4 is opened to connect to power supply, at this moment the connection direction of two electromagnet YA1, YA2 with before on the contrary, i.e. electromagnet
Interior reversed energization, magnetic force reversion, to make sunshade lens 8 cover on peep hole 10, as shown in double dot dash line part in Fig. 2.
In the present embodiment, 8 bales catch of sunshade lens prevents strong light to hurt eye on peep hole 10 when welding；Welding finishes
Afterwards, sunshade lens 8 automatically open, so as to clear view weldment.
It should be noted that the specific embodiment of the utility model is described in detail the utility model,
For those skilled in the art, it is carried out without departing substantially from the spirit and scope of the utility model various
