Problems solved by technology

The existing feeding equipment for powder raw materials is usually designed and manufactured with reference to the feeding equipment for liquid raw materials. Due to the particularity of powder raw materials, on the one hand, the powder fluidity is poor, which easily leads to uneven heating of raw materials located in different parts of the shell , which affects subsequent production and processing; on the other hand, the powder particles are small and easy to be affected by moisture. At the same time, because the diameter of the delivery pipe is smaller than the inner diameter of the shell, and the two are usually connected by a conical structure, the powder is easy to deposit here, resulting in blockage. material

Abstract

The invention provides a feeding device of powdery raw material. The feeding device can guarantee that the powdery raw material can be fully mixed and evenly heated, and deposition and blocking of the powdery raw material can be effectively prevented. The feeding device comprises a shell, a feeding hopper is arranged on the upper portion of the shell, and a stop valve and a controllable switch are arranged on a material conveying pipe at the bottom of the shell. The feeding device is characterized in that a plurality of perpendicularly distributed baffle plates are arranged in an inner cavity of the shell, every two adjacent rows of baffle plates are arranged in a staggered mode, and the top and the bottom of the inner cavity of the shell are provided with a filtering device and a powder blowing-away device respectively.

Description

technical field [0001] The invention relates to production and processing equipment using powdery substances as raw materials, in particular to a feeding device for powdery raw materials. Background technique [0002] The feeding equipment for solid raw materials or liquid raw materials has been very mature, including the shell, and the feeding hoppers and feeding pipes respectively arranged on the upper and lower parts of the shell, and the feeding equipment for liquid raw materials is equipped with a changer on the outer periphery of the shell. The heater keeps the raw material within a specified temperature range. The existing feeding equipment for powder raw materials is usually designed and manufactured with reference to the feeding equipment for liquid raw materials. Due to the particularity of powder raw materials, on the one hand, the powder fluidity is poor, which easily leads to uneven heating of raw materials located in different parts of the shell , which affect...
