Description

Technical Field

[0001] The utility model relates to the technical field of welding smoke treatment, in particular to a honeycomb filter welding smoke adsorption device. Background Art

[0002] Welding smoke mainly refers to the general term for smoke and harmful gases generated during the welding process. Welding waste gas includes welding smoke and welding fume. Smoke is a general term for smoke and dust. The welding smoke generated during the welding process contains a large amount of harmful substances, such as carbon monoxide, nitrogen oxides, sulfur dioxide and other harmful gases, as well as tiny particulate matter. These harmful substances will not only cause damage to the workers' respiratory system, so they need to be adsorbed.

[0003] The existing adsorption device cannot detect the filtered air, and cannot promptly remind the user when the filtering effect of the filter component decreases. In addition, the device needs to be shut down when cleaning the internal filter component, which affects the work efficiency.

[0004] The existing patent (Announcement No.: CN214382613U) is a honeycomb filter adsorption device, which is connected to the external pipe through the ventilation port. The air in the external pipe is pumped into the ventilation pipe and filtered through the honeycomb filter layer. After filtering by the honeycomb filter layer, it is discharged through the ventilation port at the other end. The dust concentration inside the air is sensed by the dust concentration sensor. When the dust concentration is too high, the controller sends the information to the display screen for display and reminds the surrounding personnel through the alarm. When cleaning is required, the control command is sent to the controller through the control panel. The controller closes the control valve on the corresponding ventilation pipe, and then pulls the pull plate so that the honeycomb filter layer can be slid out through the slider for cleaning.

[0005] In view of the above problems, the existing patent provides a solution, but when in use, it introduces harmful gases from the outside into the interior of the cabinet. This method cannot disperse the gas entering the interior of the cabinet, so that the honeycomb filter layer in the middle part filters more gas, and the honeycomb filter layers in the upper and lower parts filter less gas, thereby reducing the filtering effect.

[0006] Therefore, a honeycomb filter welding fume adsorption device is proposed. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0030] See also Figures 1 to 6 , the utility model provides a technical solution:

[0031] A honeycomb filter welding smoke adsorption device comprises a box body 1, an adsorption mechanism 2 for adsorbing dust in welding smoke is arranged inside the box body 1, and a guide component 3 for guiding filtered gas is arranged inside the box body 1;

[0032] The adsorption mechanism 2 includes an air intake pipe 201, an exhaust pipe 202, a dry filter 203, a connecting plate 204, an inclined plate 205 and a triangular prism 206. The air intake pipe 201 and the exhaust pipe 202 are respectively connected and arranged on the outer side walls of the box body 1. The dry filter 203 is inserted into the interior of the box body 1, the connecting plate 204 is arranged on the side wall of the dry filter 203, the inclined plate 205 is bolted to the inner wall of the box body 1, and the triangular prism 206 is bolted to the side wall of the box body 1. There are three dry filters 203 and three connecting plates 204. One end of the inclined plate 205 is tightly fitted with the side wall of the dry filter 203. The triangular prism 206 is located between two adjacent dry filters 203, and the bottom of the triangular prism 206 is tightly fitted with the bottom of the dry filter 203.

[0033] Specifically, Figure 4 As shown, a diverter plate 4 for diverting the gas entering the box 1 is bolted to the side wall of the box 1 , and the diverter plate 4 is located on one side of the air inlet pipe 201 .

[0034] Specifically, Figure 1 As shown, a mounting plate 5 is welded on the outer wall of the connecting plate 204 , and a bolt 6 is threadedly connected to the inner part of the mounting plate 5 . One end of the bolt 6 extends to the inside of the box body 1 and is threadedly connected to the box body 1 .

[0035] Specifically, Figure 1 As shown, a sealing ring 7 is bonded to the outer wall of the connecting plate 204, and the sealing ring 7 is made of rubber material.

[0036] Specifically, Figure 1 As shown, a handle 8 is bolted to the side wall of the connecting plate 204 , and a rubber sleeve 11 is bonded to the outer wall of the handle 8 .

[0037] Specifically, Figure 6As shown, a support leg 9 is bolted to the bottom of the box body 1, and an anti-skid pad 10 is bonded to the bottom of the support leg 9, and the anti-skid pad 10 is made of rubber material.

[0038] Specifically, Figure 1 As shown, an anti-corrosion layer is sprayed on the inner wall of the box body 1, and the anti-corrosion layer is made of organic silicon coating. The anti-corrosion layer is used to prevent the box body 1 from being corroded by corrosive gases in welding smoke.

[0039] When in use, external gas is introduced into the interior of the box body 1 through the air inlet pipe 201. At this time, the continuous welding smoke will be diverted by the diverter plate 4 first, and then guided to the dry filter 203 by the inclined plate 205. At this time, the triangular column 206 can block the space between two adjacent dry filters 203, so that the welding smoke can meander inside the box body 1. At the same time, the sealing ring 7 can improve the sealing effect inside the box body 1, so that the welding smoke can be fully filtered. Then the solid particles in the welding smoke will be adsorbed, and then the processed welding smoke will be discharged to the outside of the box body 1 through the exhaust pipe 202. When the dry filter 203 needs to be replaced, the bolt 6 can be taken out, and then the connecting plate 204 and the dry filter 203 can be taken out through the handle 8, and then they can be replaced or cleaned.

[0040] Specifically, Figure 3 As shown, the guide assembly 3 includes an upper arc plate 301 and a lower arc plate 302, which are bolted to the inner top wall and the inner bottom wall of the box body 1 respectively, and the upper arc plate 301 and the lower arc plate 302 are both made of stainless steel.

[0041] When the welding smoke is discharged through the dry filter 203 located at the upper and lower parts inside the box 1, the gas will be guided by the upper arc plate 301 and the lower arc plate 302, so that the gas enters the exhaust pipe 202 more quickly, thereby improving the exhaust efficiency.

[0042] By adopting the above technical solution, the problem that the existing honeycomb filter welding smoke adsorption device, when in use, introduces external harmful gases into the interior of the cabinet, and this method cannot disperse the gas entering the interior of the cabinet, so that the honeycomb filter layer in the middle part filters more gas, and the honeycomb filter layers in the upper and lower parts filter less gas, thereby reducing the filtering effect, is solved.

[0043] Working principle: when in use, the external gas is introduced into the interior of the box body 1 through the air inlet pipe 201. At this time, the continuous welding smoke will be diverted by the diverter plate 4 first, and then guided to the dry filter 203 by the inclined plate 205. At this time, the triangular column 206 can block the space between two adjacent dry filters 203, so that the welding smoke can detour inside the box body 1. At the same time, the sealing ring 7 can improve the sealing effect inside the box body 1, so that the welding smoke can be fully filtered. Then the solid particles in the welding smoke will be adsorbed, and then the processed welding smoke will be discharged to the outside of the box body 1 through the exhaust pipe 202. When the dry filter 203 needs to be replaced, the bolt 6 can be taken out, and then the connecting plate 204 and the dry filter 203 can be taken out through the handle 8, and then they can be replaced or cleaned. When the welding smoke is discharged through the dry filter 203 located at the upper and lower parts of the box body 1, the gas will be guided by the upper arc plate 301 and the lower arc plate 302, so that the gas can enter the exhaust pipe 202 more quickly, thereby improving the exhaust efficiency.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
