Filter capable of continuously working

The utility model relates to the technical field of filters, in particular to a filter capable of continuously working, which comprises a filter body, and radiating grooves communicated with an inner cavity of the filter body are arranged on the surfaces of the left side and the right side of the filter body. Mounting frames which correspond to the heat dissipation grooves in the same side of the outer wall of the filter body in position and are matched with the heat dissipation grooves in size are fixed to the surfaces of the left side and the right side of the filter body, filter screens slidably connected with the inner walls of the mounting frames are arranged in the mounting frames, and a heat dissipation mechanism for dissipating heat of the filter body is arranged in the filter body. The heat dissipation grooves are formed in the surfaces of the left side and the right side of the filter body, heat dissipation can be conducted on the interior of the filter body through the arrangement of the two instal
