| description | The utility model discloses a dust density filter device of an insulator. The dust density filter device comprises a funnel and a suction flask, wherein the bottom end of the funnel is inserted into an opening of the suction flask; an air outlet is also formed in the suction flask; the filter device also comprises an aspirator pump; the aspirator pump is communicated with the air outlet through an exhaust tube. By adopting the structure, firstly, a filter paper is put into the funnel; liquid containing dunghill is poured into the funnel; the aspirator pump is started, and extracts the air in the suction flask, so that negative pressure is generated in the suction flask. Thus, the liquid is filtered at a fast speed under the common action of the gravity and the negative pressure. Compared with the filter device for filtering just by the gravity of the liquid in the prior art, the filter speed can be greatly quickened by the filter device, so that the filter efficiency is improved. |
