Description

A kind of adjustable bleed type Blowing and sucking dust remover chamber

Technical field:

The utility model relates to a kind of adjustable bleed type Blowing and sucking dust remover chamber.

Background technology:

Before the large-sized structural parts welding, need its bevel, on sheet material workpiece, punch, the reinforcement of welding back planing face of weld when reprocessing weldment, is eliminated weld defect (digging out), generally uses carbon arc air gouging.

Defective in burr, flash, rising head and the foundry goods of heavy castings removing cast(ing) surface is used carbon arc air gouging in a large number.

Carbon arc air gouging is to utilize the high temperature electric current that produces between carbon electrode and the metal; The metal local heat to molten state; Utilize the high velocity air of compressed air (pressure 0.5-0.7Mpa) to blow these deposite metals off simultaneously, thus a kind of technological method for processing that realization is planed and cut the metal mother metal.

The carbon arc air gouging advantage: during (1) manual carbon arc air gouging, flexibility is very big, can carry out full position operation.Accessibility is good, and is very easy.When (2) removing the defective of weld seam, under electric arc, can clearly observe the shape and the degree of depth of defective.(3) noise is little, and efficient is high.When using automatic carbon arc type gas gouging, have higher precision, reduce labor intensity.

The be to use carbon-point or the graphite rod of carbon arc air gouging are made electrode, and produce electric arc between workpiece, with metal molten, and with the method for compressed air with the deposite metal blowing.In operating process, produce a large amount of carbon arc smog, dust, under compressed-air actuated stirring, site environment is made a very bad impression.

Because when work, hot flue gas is fled to top, so body top, chamber, operating room need open wide, and according to the workpiece requirement, chamber, operating room body internal area is also bigger, and it is difficult to make to the dedusting in the operating room.

Summary of the invention:

For overcoming the defective of prior art, the purpose of the utility model is to provide a kind of adjustable bleed type Blowing and sucking dust remover chamber, can carry out very resultful Blowing and sucking dust remover to carbon arc air gouging operating room indoor.

The utility model technical solution problem adopts following technical scheme:

A kind of adjustable bleed type Blowing and sucking dust remover chamber comprises the cube dirt pocket of open top, and top one end of said dirt pocket is provided with suspended hood, and the top other end is provided with the blower relative with said suspended hood, the mouth of pipe adjustable height of said blower.

The design feature of the utility model also is:

The mouth of pipe of said blower is the flat structure; Be provided with the adjustable plate consistent at said mouth of pipe intracavity bottom with mouth of pipe width; The bottom surface of said adjustable plate is fixed with sleeve; The bulb on adjusting screw(rod) top is inserted in the said sleeve, and the bottom surface of said mouth of pipe housing is installed with and said adjusting screw(rod) nut engaged; Said adjustable plate has kink, and said kink seals the mouth of pipe inner chamber of adjustable plate below all the time.

Compared with present technology, the beneficial effect of the utility model is embodied in:

The utility model is to the dirt pocket open top side draught form that is set to blow side, and the mouth of pipe blowing of blower highly is set to adjustable structure, guarantees that various operating mode occasions all can use.

Description of drawings:

Fig. 1 is the structural representation of the utility model; Fig. 2 is the partial enlarged drawing of the blower mouth of pipe; Fig. 3 is the partial enlarged drawing of adjusting screw(rod) and nut cooperation place.

Label among the figure: 1 dirt pocket, 2 suspended hoods, 3 blowers, 4 adjustable plates, 41 kinks, 5 sleeves, 6 adjusting screw(rod)s, 7 nuts.

Below pass through the specific embodiment, and combine accompanying drawing that the utility model is described further.

The specific embodiment:

Embodiment: referring to Fig. 1-3; Dirt pocket 1 is the cube structure of open top, and its top one end is provided with suspended hood 2, and suspended hood is connected with the ventilation and dust removal system; Dust laden air to the dirt pocket top aspirates; The top other end of dirt pocket 1 is provided with the blower 3 relative with suspended hood 2, is to be fit to various operating mode use, and the mouth of pipe height of blower 3 is set to adjustable structure.

Concrete structure is: the mouth of pipe of blower 3 is the flat structure, is provided with the adjustable plate consistent with mouth of pipe width 4 at mouth of pipe intracavity bottom, is fixed with sleeve 5 in the bottom surface of adjustable plate 4; The bottom surface of mouth of pipe housing is installed with nut 7, and the adjusting screw(rod) 6 that cooperates with nut 7 passes from mouth of pipe housing bottom, and the top bulb of adjusting screw(rod) is inserted in the sleeve 5; Rotating adjusting screw(rod) 6 can make adjustable plate go up and down; Change blowing height and wind speed, leak out in its below when avoiding adjustable plate to raise, and adjustable plate 4 is set to approximate L shaped; Be that adjustable plate 4 has kink 41, this kink 41 seals the mouth of pipe inner chamber below the adjustable plate 4 all the time when adjustable plate goes up and down.
