Dry powder feeding device

Abstract

The invention provides a dry powder feeding device, and belongs to the field of construction and building materials. The dry powder feeding device comprises a housing, a stirring roller and a magnetic part, wherein the upper and lower ends of the housing are respectively provided with a feeding hole and a discharge hole; the stirring roller is vertically arranged in the middle of the housing; the upper end of the stirring roller is provided with a tapered cap; the lower end of the stirring roller is connected with a motor for driving the stirring roller to rotate; the motor is fixed on the inner wall of the housing; the magnetic part is arranged on the inner wall of the housing; the cap edge of the tapered cap extends out of the outer wall of the stirring roller; and a channel for allowing dry powder to pass through is formed between the magnetic part and the stirring roller. According to the dry powder feeding device provided by the invention, the rotary stirring roller is arranged, so that the dry powder while entering is thrown to the magnetic part on the housing by virtue of the tapered cap on the stirring roller, and therefore, dry powder blocks can be scattered, metal impurities mixed in the dry powder also can be adsorbed, and the metal impurities are prevented from damaging machine equipment; and the dry powder feeding device is simple to operate and beneficial for popularization.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a dry powder feeding device. Background technique [0002] In the process of making building materials and coatings, various dry powder materials need to be used. These dry powder materials are stored in different storage bins due to different materials, and these different dry powder materials need to be mixed in the subsequent processing process. [0003] In the production and transportation of dry powder, a large number of metal objects need to be contacted, and some metal parts such as nails, metal chips, etc. will enter it. These metal impurities can easily damage the mixing page of the mixer after entering the mixer and other equipment, resulting in loss, and the existing mixing system cannot mix the dry powder materials well, resulting in poor quality of the final building material coating, especially when the dry powder is damp and agglomerated, it is more likely to be u...

Problems solved by technology

[0003] In the production and transportation of dry powder, a large number of metal objects need to be contacted, and some metal parts such as nails, metal chips, etc. will enter it. These metal impurities can easily damage the mixing page of the mixer after entering the mixer and other equipment, resulting in loss, and the existing mixing system cannot mix the dry powder materials well, resulting in poor quality of the final building material coating, especially when the dry powder is wet and agglomerated, it is more prone to uneven mixing, and at the same time it cannot be mixed Metal impurities in dry powder are removed, so there is an urgent need for a feeding device that can remove metal impurities and mix dry powder evenly during the feeding process of machinery and equipment
