Water adding system of powder mixer

Abstract

The invention discloses a water adding system of a powder mixer. The water adding system comprises the powder mixer, the water adding system of the powder mixer further comprises a water adding tank and an air compressor, a water adding pipe is connected to the water adding tank, a high-pressure air output pipe of the air compressor is provided with two high-pressure gas branches, one high-pressure gas branch is connected to the water adding tank and communicates with an inner cavity of the water adding tank, a top cover of the powder mixer is provided with a water adding nozzle which communicates with the other high-pressure gas branch and the water adding pipe at the same time and mixes introduced high-pressure gas and water flow added through the water adding pipe, the two high-pressuregas branches are correspondingly provided with gas valves, and the water adding pipe is provided with a water adding valve. According to the water adding system of the powder mixer, the atomization of the water flow is fully guaranteed, so that the effect of uniformly adding the water into powder is achieved, moreover, the water adding amount is accurately controlled, and then the advantages andeffects that the product forming quality is greatly improved, and the sintering percent of pass is high are achieved.

Description

technical field [0001] The invention relates to a water adding system for a powder material mixer. Background technique [0002] In the process of making ceramic plates, various raw materials need to be added with water and stirred evenly, and then molded after being evenly stirred, and finally dried in a drying kiln. At present, there are several kinds of powder materials with 40-300 mesh of ceramic plate powder, and water is added after mixing. If the water is not added uniformly, a large number of "mud balls" ("snowball" effect) will be formed after stirring, which will cause adverse effects on the homogenization of the powder materials. Influence, the same piece of product is easy to bend when extruded (partial moisture is different), and the same piece of product may be uneven in color and have ribbons after firing. However, the current water-adding nozzle of the mixer adopts the "shower" type, which has two disadvantages: 1. It is easy to spray out the water column, r...

Problems solved by technology

At present, there are several kinds of powder materials with 40-300 mesh of ceramic plate powder, and water is added after mixing. If the water is not added uniformly, a large number of "mud balls" ("snowball" effect) will be formed after stirring, which will cause adverse effects on the homogenization of the powder materials. Influence, the same piece of product is easy to bend when extruded (partial moisture is different), and the same piece of product may be uneven in color after firing, with ribbons

However, the current water-adding nozzle of the mixer adopts the "shower" type, which has two disadvantages: 1. It is easy to spray out the water column, resulting in uneven water addition to the powder, which eventually leads to the "snowball" effect, resulting in the disadvantage of poor forming quality of the ceramic plate; 2. The accuracy of controlling the amount of water added is poor, so the water content in the powder is not easy to control, and it is difficult to control the subsequent drying process, resulting in differences in product quality in different batches
