Detailed Description

It should be noted that, in the present invention, the position or position relation indicated by the terms such as "upper", "lower", "front", "back", etc. is the position or position relation shown in the drawings, and the relation words determined for the convenience of describing the structural relation of the components of the present invention are not specific to any component of the present invention, and the limitation of the present invention cannot be understood.

The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings:

as shown in fig. 1, the bin type sawdust separator comprises a main body 1, a grid mounting opening 2, a storage bin 3 and an inclined grid 4 mounted inside the main body 1. The main body 1 is a hollow cylinder with an upper opening and a lower opening, and the upper end of the main body is provided with a feeding hole of the sawdust separator and is connected with a powder outlet of the fine powder separator; the lower end of the dust bin is provided with a discharge hole of the sawdust separator and is communicated with the powder bin. Set up grid installing port 2 on one side upper portion of main part 1 for with oblique grid 4 from the outside installation enter main part 1 in and change oblique grid 4, through welded fastening between grid installing port 2 and the main part 1, its width equals with the diameter of main part 1 for the vertical inside wall of grid installing port 2 is tangent with the inside wall of main part 1, and oblique grid 4 can be followed grid installing port 2 and installed when advancing main part 1, closely laminate between can and the main part 1, no crack. Grid installing port 2 is to oblique top opening, and the contained angle between opening direction and the main part 1 is 45, adds in the outer end of grid installing port 2 and establishes protective cover 6, and protective cover 6 is inboard to be salient inwards for support oblique grid 4 and fix, prevent simultaneously that outside debris from getting into the saw-dust separator.
