Dry-type mixing device

Abstract

The invention discloses a dry-type mixing device comprising a mixing tank body, the mixing tank body is connected with a feed pipe which is inserted in an inner chamber of the mixing tank body from the lower part of the mixing tank body, the bottom of the feed pipe is provided with a feed port, a feed pipe section located in the mixing tank body is provided with a plurality of discharge holes from top to bottom, a stirring shaft driven by a power device is in the mixing tank body and is rotationally connected with the mixing tank body, the stirring shaft is connected with stirring blades, the upper part of the side wall of the mixing tank body is provided with a large-grain supply pipe, the lower part of the mixing tank body is shaped as an inverted cone, the bottom of the mixing tank body is provided with a discharge tube, a discharge shaft and a discharge motor are symmetrically arranged on a inverted-cone shaped section of the mixing tank body, the discharge shaft is obliquely upwards stretched out and is driven to rotate by the discharge motor, and the discharge shaft is provided with material-uniforming blades. The dry-type mixing device has the advantages of even feed amount, low tendency to lead feed separation, and even material mixing.

Description

technical field [0001] The invention relates to a dry mixing device. Background technique [0002] The currently used dry-mixed mortar tank includes a tank body, the feed pipe is located in the center of the tank body, the lower end of the feed pipe extends out of the tank body as a feed inlet, and the material is discharged into the tank body from its upper end. During the structure, the entry of small particle materials is uneven, and the uneven feeding amount leads to segregation of the feeding material; moreover, the density of the material at the outlet of the lower end of the tank body increases and the feeding is uneven, resulting in uneven mixing of the dry-mixed mortar and isolate again. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a dry mixing device with a uniform feeding amount, which is not easy to cause the segregation phenomenon of the feeding material and evenly mixes the materials.
