As welding fume pollution has been paid more and more attention by people, the application of welding fume purification products has emerged. However, there are still quite a lot of disadvantages in the high negative pressure welding purifier currently used. Taking the filter cartridge type dust collector of the prior art as an example, because the filter cartridge is used as the dust removal device, the whole equipment is bulky and inconvenient to move. The use is limited; at the same time, when the filter device is saturated, it is difficult to clean the dust and easily produces secondary pollution; moreover, the energy consumption is large and the maintenance cost is high.

Therefore, how to develop a welding fume purifier that is small in size, wide in application range and able to solve the difficulty of cleaning dust is a problem that those skilled in the art have always wanted to solve.

The purpose of this utility model is to provide a movable high negative pressure welding fume purification device that can solve the defects of the prior art. It satisfies the requirements of wide application range and easy dust removal through reasonable structure setting and convenient automatic dust removal function. requirements.

In order to achieve the above purpose, the movable high negative pressure welding fume purification device of the present invention includes a dust removal mechanism and a dust removal mechanism. The dust removal mechanism includes an air inlet, a dust bag, and a high-pressure fan. The air inlet passes through The pipeline is connected to the dust bag, and the dust bag is connected to the high-pressure fan through the pipe, and the high-pressure fan is connected to the air outlet; the dust cleaning mechanism is connected to the dust bag; because the dust bag and the high-pressure fan are used, the whole movable The volume of the high negative pressure welding fume purification device is obviously smaller than the purifiers in the prior art.

Further, the dust cleaning mechanism includes a high-pressure gas bag and an ash-collecting bucket, and the high-pressure gas bag is connected to the dust-removing bag through a pulse valve; the bottom of the dust-removing bag is connected to the dust-collecting bucket. The new mobile high negative pressure welding fume purification device realizes the automatic dust removal function, and the regular bag dust removal and dust collection tube cleaning saves manpower and material resources.

Further, an air outlet muffler is provided at the air outlet of the dust removal mechanism.

Further, the dust removal bags of the dust removal mechanism are all set in the vacuum chamber.

Further, the movable high-negative-pressure welding fume purification device also includes a housing, and the housing for protecting each structure is wrapped around the high-pressure gas bag, the pulse valve and the high-pressure blower.

Further, the movable high negative pressure welding fume purification device includes universal wheels and directional wheels, and the universal wheels and directional wheels are both arranged at the bottom of the entire movable high negative pressure welding fume purification device.

The movable high negative pressure welding fume purification device with the above structure has the following advantages: 1. Small size, easy to carry and move; 2. It has automatic dust cleaning function, and only needs to clean the dust bucket regularly; 3. Wide application range , It can be applied to off-site welding, inner wall welding of pressure vessels, subsection assembly line in shipyards, and fume treatment in welding operations in small cabins.

Detailed ways

In order to better understand the purpose, features and functions of the utility model, the structures and functions of the preferred embodiments of the utility model are described in detail below in conjunction with the accompanying drawings.

As shown in Fig. 1, Fig. 2 and Fig. 3, the movable high negative pressure welding fume purification device described in this embodiment includes a dust removal mechanism and a soot removal mechanism, and the dust removal mechanism is used to remove dust from the dust-containing gas, which includes There are an air inlet 10, a dust bag 11, a high-pressure fan 1, a pipe connected to the high-pressure fan, an air outlet 12, and an air outlet muffler 9 arranged at the air outlet. The outlet is connected, which is connected to the air inlet of the dust removal bag through a pipe, and the air outlet of the dust removal bag is connected to the pipe leading to the high-pressure fan. The high-pressure fan 1 is used to suck the gas in the dust removal mechanism to provide power for the flow of the gas. It is connected to the air outlet 12; in addition, in this embodiment, the dust removal mechanism has three dust removal bags arranged side by side, and the dust removal bags are all arranged in the vacuum chamber 3;

The working principle of the dust removal mechanism is: polluted air enters the dust removal bag through the only air inlet 10, after passing through the dust removal bag, the dust is adsorbed on the outer wall of the dust removal bag, and the clean air after dust removal passes through the dust removal bag in the high-pressure fan. Under the action, it flows out from the air outlet through each pipe.

The dust removal mechanism includes a pulse valve 5, a high-pressure air storage bag 4, and an ash collection bucket 2. The high-pressure air storage bag 4 is connected to the dust removal bag 11 through the pulse valve, and the bottom of the dust removal bag 11 is connected to the dust collection bucket. 2 connection; when working, the pulse valve acts, and the high-pressure gas in the high-pressure gas storage bag enters the dust bag 11 under the action of pressure, and the dust attached to the outer wall of the dust bag is blown to the dust collection bucket 2 by using the impact force of the high-pressure gas , thus ending the collection of dust; the opening of the pulse valve is intermittent, when the dust in the dust bag accumulates to a certain extent, the pulse valve acts to clean the dust; when the dust in the dust collection bucket 2 accumulates to a certain extent, It only needs to be removed and cleaned; it can be seen from Fig. 1, Fig. 2 and Fig. 3 that the ash collecting bucket 2 is detachably fixed to the lower part of the vacuum chamber through the connecting structure.

The movable high negative pressure welding fume purifying device described in this embodiment also includes a housing 6, which covers the high-pressure gas storage bag, the pulse valve and the outside of the high-pressure blower to protect each structure. 1, 2 and Fig. 3, it can be seen that the vacuum chamber 3 and the casing 6 are detachably connected together through the connection structure; further, it also includes a universal wheel 8 and an orientation wheel 7, and two Two directional wheels, the universal wheel 8 and the directional wheel 7 are all arranged at the bottom of the whole movable high negative pressure welding fume purification device, so as to realize the characteristics of wide application range and convenient movement.

The above is only a preferred embodiment of the present utility model, and it should be pointed out that for those skilled in the relevant fields, without departing from the principle of the present utility model, the slight modifications and improvements made should also be regarded as Belong to the protection scope of the utility model.
