[0034] The following is a further detailed description through specific implementation manners:

[0035] The reference numerals in the accompanying drawings of the specification include: the first box body 1, the second box body 2, the third box body 3, the air inlet 4, the air outlet 5, the air guide plate 6, the support plate 7, the filter element 8, the outer shell 9, the filter cotton 10, the skeleton 11, and the cardboard 12.

[0036] As shown in the Figures 1-7 accompanying drawings, this embodiment shows a paint mist filter convenient for transportation, including a first box body 1, a second box body 2, and a third box body 3. The first box body 1 and the second box body 2 are arranged adjacent to each other left and right. The first box body 1 and the second box body 2 are arranged on the third box body 3, and the bottoms of the first box body 1 and the second box body 2 are both communicated with the third box body 3. Among them, an air inlet 4 is arranged on the first box body 1, an air outlet 5 is arranged on the second box body 2, and an air guide plate 6 is arranged in the third box body 3. The air guide plate 6 is integrally V-shaped.

[0037] Specifically, the air inlet 4 of the first box body 1 is arranged on the side wall far from the second box body 2, and the air outlet 5 of the second box body 2 is arranged on the side wall far from the first box body 1.

[0038] Among them, as shown in Figure 2 and 3As shown, the structures of the first box body 1 and the second box body 2 are the same. The bottoms of the first box body 1 and the second box body 2 are provided with openings, and at the same time, the top of the third box body 3 is provided with an opening, so that the bottoms of the first box body 1 and the second box body 2 are communicated with the third box body 3. A support plate 7 is also provided on the top of the third box body 3. The support plate 7 is connected to the first box body 1 and the second box body 2, and also supports the first box body 1 and the second box body 2. The support plate 7 can be connected to the first box body 1 and the second box body 2 by glue.

[0039] Among them, the first box body 1, the second box body 2 and the third box body 3 can all be made of corrugated cardboard boxes. Each box body can be separated and folded during transportation, which is convenient for transportation.

[0040] Among them, the first box body 1, the second box body 2 and the third box body 3 form a filtration chamber. The first box body 1 is an air inlet chamber, and the second box body 2 is an air outlet chamber. Similarly, the air guide plate 6 can also be set to be integrally in a W or U shape to ensure the degree of blocking of the waste gas by the air guide plate 6.

[0041] The working principle of the paint mist filter in this embodiment is: Place the paint mist filter in the waste gas passage. The waste gas enters the filtration chamber from the air inlet 4, and then encounters the air guide plate 6 downward. After passing through the third box body 3, the waste gas then escapes upward from the air outlet 5 of the second box body 2. During the encounter with the air guide plate 6, the paint mist in the waste gas is adsorbed on the air guide plate 6, thereby realizing the filtration of the waste gas.

[0042] Among them, in order to increase the degree of blocking of the waste gas by the air guide plate 6, the V-shaped opening of the air guide plate 6 below the first box body 1 is set upward, and the V-shaped opening of the air guide plate 6 below the second box body 2 is set downward, so that the paint mist in the waste gas moving downward from the air inlet 4 into the filtration chamber fully contacts the air guide plate 6 with the V-shaped opening upward, and the waste gas in the lower part of the filtration chamber moves upward to fully contact the air guide plate 6 with the V-shaped opening downward, thereby improving the adsorption rate of the paint mist in the waste gas and improving the filtration effect.

[0043] Specifically, the V-shaped opening of the air guide plate 6 below the middle of the first box body 1 and the second box body 2, that is, the air guide plate 6 below the support plate 7, is set toward the air inlet chamber side. Such a setting will enable the waste gas from the bottom of the air inlet chamber to the bottom of the air outlet chamber to fully contact the air guide plate 6 to improve the paint mist adsorption rate.

[0044] Among them, the opening degree of the air guide plate 6 is gradually increased from top to bottom. The opening degree of the air guide plate 6 gradually increases from top to bottom, realizing the control of the air flow velocity gradient and optimizing the filtration efficiency.

[0045] Among them, a filter element 8 can be provided inside the first box body 1 and / or the second box body 2. In this embodiment, the filter element 8 is provided in the second box body 2. In this embodiment, the filtration effect is improved by setting the filter element 8.

[0046] In some embodiments, the filter element 8 can also be disposed within the first housing 1, or the filter element 8 can be disposed within both the first housing 1 and the second housing 2 simultaneously.

[0047] As shown in Figure 8 and 9 the filter element 8 includes a housing 9, filter cotton 10, and at least two frameworks 11. The frameworks 11 are disposed within the housing 9, and the filter cotton 10 is disposed between the frameworks 11. The filter cotton 10 is distributed in an S shape between the frameworks 11. A modular filter element 8 is disposed on the inner side of the housing, and a composite structure of the frameworks 11 and the filter cotton 10 is adopted. The filter cotton 10 is arranged in an S-shaped meandering manner, increasing the contact area while maintaining a low air resistance.

[0048] As shown in Figure 7 cardboards 12 are disposed on the front wall and the rear wall of the third housing 3, and card holes are provided on the cardboards 12. A limit buckle can be disposed within the card holes to enable the air guide plate 6 to be snap-connected within the card holes, or the air guide plate 6 can be directly adhered within the card holes with glue.

[0049] In the above embodiments, both the housing and the air guide plate 6 are made of paper materials, facilitating connection therebetween and facilitating folding and stacking for transportation.

[0050] The above are only embodiments of the present utility model. Specific structures and common knowledge such as characteristics well known in the art are not described in detail herein.
