Dust collector
A dust collector for catching dust generated by temperature drop comprises a box, a plurality of separating boards, a plurality of catch boards, and a plurality of baffle boards. The separating boards partition the box to form an air flow channel. The catch boards and the baffle boards are staggered in the air flow channel; a portion of the catch boards are arranged in a central column to form a superimposition region along the vertical direction. The pores of the catch boards in the superimposition region are overlapped to make the air flow pour into the air flow channel easily. The baffle boards are staggered at the left or right of the catch boards, whereby the air flow takes more time to have a longer travel in the air flow channel, and dust is not accumulated in a single area but uniformly caught by the catch boards.
1. A dust collector for catching dust in an air flow, comprising
a box;
a plurality of separating boards partitioning the box to form an air flow channel, wherein the air flow channel has an inlet and an outlet, and wherein the air flow channel is divided into an incoming region, a first catch region, a second catch region, and an outgoing region;
a plurality of catch boards respectively being located in the air flow channel and having a plurality of pores, wherein diameter of the plurality of pores on the catch boards in the first catch region, the second catch region or the outgoing region positively correlates with distance between the catch boards and the outlet, and wherein number of the plurality of pores on the catch boards positively correlates with distance between the catch boards and the inlet; and
a plurality of baffle boards arranged in the incoming region and aligned in rows and columns with the catch boards, wherein the incoming region has a superimposition region at a middle thereof along a direction from the inlet to the outlet, and wherein the plurality of pores of the catch boards in the superimposition region are overlapped.
2. The dust collector according to claim 1 , wherein the baffle board nearest to the inlet has a plurality of pores.
3. The dust collector according to claim 1 further comprising a plurality of fixing rods penetrating and fixing the baffle boards and the catch boards.
4. The dust collector according to claim 1 , wherein the pores of the catch boards respectively arranged in the first catch region and the second catch region are staggered.
5. The dust collector according to claim 4 , wherein the catch boards arranged in the first catch region have a length of 155.5-156.5 mm and a width of 149.5-150.5 mm, and the pores thereof have a diameter of 19.8-20.2 mm.
6. The dust collector according to claim 4 , wherein the catch boards arranged in the second catch region have a length of 151.5-152.5 mm and a width of 90.8-91.2 mm, and the pores thereof have a diameter of 14.8-15.2 mm.
7. The dust collector according to claim 1 , wherein the catch boards arranged in the incoming region have a length of 239.5-240.5 mm and a width of 131.5-132.5 mm, and the pores thereof have a diameter of 14.8-15.2 mm.
8. The dust collector according to claim 1 , wherein the catch boards arranged in the outgoing region have a length of 151.5-152.5 mm and a width of 49.8-50.2 mm, and the pores thereof have a diameter of 9.8-10.2 mm.
