The filter equipment of box structure can collect more tectorial membranes, will filter the mesh setting simultaneously on the lateral wall and not set up on the bottom surface, because it is more close to the vent to filter the mesh, and suction is stronger, but relatively, the farther suction greatly reduced who filters the mesh apart from the vent, can not play absorbent effect even, influences filter equipment's actual filter area. The distance from each side face to the ventilation opening is close, so that the adsorption force of the filter meshes on each side face is basically consistent, the actual filter area is larger, and the adsorption and filtration effects are better.
Further, filter equipment includes bottom plate, outer panel, interior plate, left side board, right side board and apron, the outer panel outside is equipped with the handle, seted up on the apron can with collect mouthful just right upper shed, filter the mesh distribution on interior plate, left side board, right side board, the negative pressure intracavity is equipped with and bears filter equipment's separation blade, simultaneously drawer hole has been seted up on the lateral wall in negative pressure chamber, filter equipment can follow drawer hole department pushes and makes the outer panel with drawer hole forms sealed setting. Therefore, the filter device can be conveniently taken out from the negative pressure cavity and the adsorbate in the filter device can be poured out.
Furthermore, the inner side plate is pluggable, and after the inner side plate is pulled out, adsorbates in the filter device can be poured out easily.
Furthermore, the collecting port is of a funnel-shaped structure, so that the negative pressure area of the collecting port is enlarged, and the adsorption efficiency of the utility model is improved.
Furthermore, the bottom of the rack is provided with a roller for supporting, so that the position can be conveniently moved at any time.
Furthermore, the vent is the mesh structure, further strengthens the filter effect, prevents that adsorbate from getting into air-blast device.
Therefore, compared with the prior art, the utility model has the following characteristics: 1. the blower device starts, and the negative pressure chamber can produce the negative pressure with collecting near mouthful operation station, and the tectorial membrane that is torn down can be inhaled the negative pressure intracavity, and the discarded object of being inhaled the negative pressure intracavity all can be intercepted by filter equipment, avoids being inhaled the blower device in, and whole collection efficiency is high, and factor of safety is high simultaneously, does not influence workman's operation.
