The exhaust gas after spraying can be filtered through the first filter element, the second filter element and the second filter element in sequence. However, if the filter element is not replaced in time after saturation, it will affect the subsequent exhaust gas filtering effect. Therefore, those skilled in the art provide a gas treatment device for environmentally friendly paint spraying equipment to solve the problems raised in the above background technology.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] When implementing: Figure 1-4 As shown, a gas treatment device for environmentally friendly paint spraying equipment includes:

[0023] The box body 1 has an air inlet pipe 101 on one side and an exhaust pipe 102 on the other side.

[0024] The filter assembly 2 is arranged inside the box 1 and is used to filter the exhaust gas;

[0025] Auxiliary component 3, the auxiliary component 3 is arranged inside the box body 1;

[0026] Among them, the filter assembly 2 includes a connecting shell 201 fixedly connected to the inner top wall of the box body 1, the inner wall of the connecting shell 201 is threadedly connected to a connecting block 204, the top of the connecting block 204 passes through the box body 1 and is fixedly connected to a cover plate 203, the surface of the connecting shell 201 is provided with evenly distributed exhaust grooves 209, and the bottom of the connecting shell 201 is provided with evenly distributed through holes 202.

[0027] The air intake pipe 101 is used to introduce the exhaust gas generated during the painting process, wherein the exhaust gas can be actively blown into the interior of the air intake pipe 101 by means of an air pump or a fan. Equipment such as air pumps or fans are relatively mature components in existing technical applications and will not be described in detail here.

[0028] like Figure 2 、 Figure 3 and Figure 4 As shown, a mounting shell 211 is provided at the bottom of the connecting block 204 , an air inlet channel is opened at the bottom of the mounting shell 211 , and a filter element 210 is filled inside the mounting shell 211 , which is an activated carbon material component.

[0029] A groove 207 is formed on the upper surface of the mounting shell 211 , and through slots 208 are evenly distributed on the surface of the mounting shell 211 and communicate with the groove 207 .

[0030] An indicator rod 205 is fixedly connected to the top of the mounting shell 211 . The upper end of the indicator rod 205 passes through the cover plate 203 . A spring 206 is fixedly connected to the surface of the indicator rod 205 . The other end of the spring 206 is fixedly connected to the inner wall of the connecting block 204 .

[0031] The gas injected into the housing 1 can be guided by the auxiliary assembly 3 so that the gas can only be injected into the interior of the connecting shell 201 through the through hole 202 and then introduced into the interior of the mounting shell 211 through the air inlet passage. During this process, the gas can be adsorbed and filtered by the filter element 210 made of the activated carbon material. The filtered gas can be guided out of the interior of the mounting shell 211 through the groove 207 and the through groove 208, and then introduced into the interior of the housing 1 through the exhaust groove 209, and finally discharged through the exhaust pipe 102.

[0032] As the filter element 210 absorbs harmful substances in the exhaust gas, the weight of the filter element 210 will gradually increase, thereby overcoming the elastic force of the spring 206 and driving the mounting shell 211 to gradually move downward. During this process, the indicator rod 205 can be driven to retract into the interior of the connecting block 204. The staff can judge whether the filter element 210 is saturated by observing the height of the indicator rod 205, so as to facilitate timely replacement and avoid the situation where the filtering effect of the subsequent exhaust gas of the filter element 210 decreases after the filter element 210 is saturated.

[0033] like Figure 2 、 Figure 3 and Figure 4 As shown, the auxiliary component 3 includes a partition 301 fixedly connected to the inner wall of the box body 1, the top of the partition 301 is in contact with the bottom of the connecting shell 201, and the top of the partition 301 is provided with an exhaust hole 302 connected to the air inlet channel, and a liquid storage chamber is formed between the bottom of the partition 301 and the inner wall of the box body 1, and the interior of the liquid storage chamber is filled with purified water.

[0034] The auxiliary component 3 also includes a connecting pipe 303 arranged inside the box body 1. One end of the connecting pipe 303 is connected to the air inlet pipe 101, and the other end of the connecting pipe 303 passes through the partition 301 and is connected to the air injection pipe 304. The air injection pipe 304 is spirally arranged inside the liquid storage cavity.

[0035] The exhaust gas introduced through the air intake pipe 101 can be introduced into the interior of the air injection pipe 304 under the action of the connecting pipe 303. During this process, the spiral air injection pipe 304 can enable the exhaust gas injected into the liquid storage chamber to stir the purified water, thereby improving the mixing effect of the purified water and the exhaust gas and improving the purification effect. Finally, the exhaust gas is discharged from the purified water in the form of bubbles and introduced into the air intake channel through the exhaust hole 302. Finally, it is filtered under the action of the filter component 2 and discharged through the exhaust pipe 102.

[0036] When the present invention is in use, the air inlet pipe 101 is used to introduce the exhaust gas generated during the painting process. The exhaust gas introduced through the air inlet pipe 101 can be introduced into the interior of the air injection pipe 304 under the action of the connecting pipe 303. During this process, the spiral air injection pipe 304 can enable the exhaust gas injected into the liquid storage chamber to stir the purified water, thereby improving the mixing effect of the purified water and the exhaust gas and improving the purification effect. Finally, the exhaust gas is discharged from the purified water in the form of bubbles and introduced into the air inlet channel through the exhaust hole 302. Finally, it is filtered under the action of the filter assembly 2 and discharged through the exhaust pipe 102. As the filter element 210 absorbs harmful substances in the exhaust gas, the weight of the filter element 210 will gradually increase, thereby overcoming the elastic force of the spring 206 and driving the mounting shell 211 to gradually move downward. During this process, the indicator rod 205 can be driven to retract into the interior of the connecting block 204. The staff can judge whether the filter element 210 is saturated by observing the height of the indicator rod 205, so as to facilitate timely replacement and avoid the situation where the filter element 210 loses its filtering effect on subsequent exhaust gas after saturation.

[0037] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
