The invention relates to a portable paint filtering device which comprises a bottom plate. Two L-shaped support plates are symmetrically installed on the upper end face of the bottom plate, a feed hopper is installed between the upper ends of the two L-shaped support plates which play a role of fixing and supporting the feed hopper, an S-shaped filter
pipe is connected to the lower end of the feed hopper, a sundry
pipe is connected to the lowest portion of the left end of the S-shaped filter
pipe, a
screw cap is installed at the lower end of the sundry pipe through a thread, an operator only needs to manually rotate the
screw cap to open the sundry pipe, the inner wall of the middle portion of the S-shaped filter pipe is provided with a first filter disc which is uniformly provided with first filter holes, one-pass
filtration is conducted on paint through the first filter holes formed in the first filter disc, large impurities are removed, and residual large impurities can be taken out through the sundry pipe. According to the portable paint filtering device, on the premise of the low cost, the automatic and rapid filtering function of the paint can be achieved, the portable paint filtering device has the advantages of being simple in structure, low in cost, high in
filtration efficiency and the like, and the production efficiency of the paint is greatly improved.
