[0022] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-Figure 6As shown, the fume removal device for the welding robot workroom provided in this embodiment includes a cabinet 1, a centrifugal fan 3 and a filter assembly 4; the centrifugal fan 3 and the filter assembly 4 are both arranged in the cabinet 1; the cabinet 1 is provided with an air inlet 111 and an air outlet 131. Those skilled in the art can understand that the operation of the centrifugal fan 3 sucks the air mixed with welding smoke in the low airspace of the workroom into the cabinet 1, filters the welding smoke through the filter assembly 4, and then discharges the filtered air from the air outlet 131, and the cycle is repeated, so that the air in the low airspace of the workroom can be purified. The centrifugal fan 3 is a common technical means in this field and will not be described in detail here.

[0024] Furthermore, the cabinet 1 is provided with a first partition 18; the filter assembly 4 includes four groups of filters 43; the filter 43 is a cylindrical shape with one side open; the first partition 18 is provided with four groups of first through holes 181; the four groups of filters 43 are all opened upward and arranged at the bottom of the first partition 18, and are respectively arranged at the four groups of first through holes 181. It can be understood by those skilled in the art that the air mixed with welding smoke from the outside is sent into the filter 43 by the centrifugal fan 3, and then filtered by the filter 43, the welding smoke particles are adsorbed on the inner wall of the filter 43, and the air passes out from the inner wall of the filter 43, thereby completing the purification of the air. It can be understood by those skilled in the art that the filter 43 is a common technical means in the field and will not be described in detail here.

[0025] Furthermore, the filter assembly 4 further includes two groups of first crossbeams 42 and six groups of connecting columns 41; one connecting column 41 is fixed to each of the two ends and the middle of the two groups of first crossbeams 42; the other ends of the connecting columns 41 are fixed to the first partition 18; the bottom of the filter 43 is fixed to the first crossbeam 42. Those skilled in the art can understand that the first crossbeam 42 can play a supporting and stabilizing role, preventing the filter 43 from tilting, thereby preventing the air mixed with welding smoke from flowing out from between the filter 43 and the first partition 18, reducing the purification effect.

[0026] Furthermore, the cabinet body 1 is enclosed by a first side panel 13 , a front panel 12 , a second side panel 14 , a rear panel 15 , a bottom panel 16 and a top panel 11 ; the air inlet 111 is opened on the top panel 11 ; and the air outlet 131 is opened on the first side panel 13 .

[0027] Furthermore, the first partition plate 18 is tightly connected to the first side plate 13, the front panel 12, the second side plate 14 and the rear panel 15 on all sides. Those skilled in the art will appreciate that such a design can improve the purification effect.

[0028] Furthermore, a second partition 17 is provided in the cabinet body 1; a second through hole 171 is provided on the second partition 17; the centrifugal fan 3 is fixed on the top of the second partition 17 and is located at the second through hole 171; the four sides of the second partition 17 are tightly connected to the first side panel 13, the front panel 12, the second side panel 14 and the rear panel 15 respectively; the second partition 17 is arranged above the first partition 18.

[0029] Furthermore, the welding robot workroom fume removal device provided in this embodiment further includes two groups of blowing assemblies and a gas storage tank 21; the two groups of blowing assemblies are connected to the gas storage tank 21; the gas storage tank 21 is fixed to the outer wall of the rear panel 15 through an angle iron 22. Those skilled in the art can understand that the gas storage tank 21 is inflated by an external high-pressure air pump, thereby providing high-pressure gas to the blowing assembly.

[0030] Further, the spray assembly includes a first pipe 23 and two groups of branch pipes 24; the two groups of branch pipes 24 are fixed on the outer wall of the first pipe 23 and are connected to the first pipe 23; the two groups of branch pipes 24 are respectively inserted into two groups of filters 43. Those skilled in the art can understand that the high-pressure gas is provided to the first pipe 23 through the gas storage tank 21, and then sprayed from the branch pipes 24, and the sprayed high-pressure gas can impact the inner wall of the filter 43, so as to clean the smoke and dust adsorbed on the inner wall of the filter 43, thereby improving the filtering effect of the filter 43.

[0031] Furthermore, one end of the first pipe 23 is blocked by a plug 26, and the other end is connected to the outlet of the pulse valve 25 after passing through the rear panel 15; the inlet of the pulse valve 25 is connected to the gas storage tank 21; the first pipe 23 is arranged between the first partition 18 and the second partition 17. Those skilled in the art can understand that the pulse valve 25 is a common technical means in the field and will not be described in detail here. Through the control of the pulse valve 25, high-pressure gas can be blown into the filter 43 at a fixed time, which will not affect the filtering effect of the filter 43 on the one hand, and can also reduce the use of high-pressure gas, thereby reducing energy consumption.

[0032] Furthermore, the fume removal device for the welding robot workroom provided in this embodiment further includes a hose (not shown in the figure); one end of the hose is fixed to the air inlet 111. Those skilled in the art can understand that the hose is placed in the area where fume removal is required according to the requirements of the welding position, so as to quickly purify the area where fume removal is required.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
