A mixing and drying equipment for plastic particles

Abstract

The invention discloses mixing and drying equipment for plastic particles, which comprises a motor, a hardened reducer and an inverted conical cylinder with a built-in stirring shaft; the motor, the hardened reducer and the inverted conical cylinder are fixedly connected in sequence, and The innovation is that: the upper surface of the inverted conical cylinder is provided with a material inlet near the left end, and the bottom is provided with a material outlet, and the bottom outlet is provided with a discharge valve; the inside of the inverted conical cylinder is provided with an outer spiral device and inner spiral device; the present invention is mainly used for mixing and drying of plastic particles. On the basis of the traditional mixing dryer principle, the inner spiral device and the outer spiral device are arranged in the middle, and a part of the material is dislocated and lifted. Scattering, and at the same time, there is a spiral belt on the periphery to disrupt the materials brought up irregularly, so as to better achieve the renewal and diffusion of materials in the whole circumference, achieve the effect of rapid mixing and uniformity, improve production efficiency, and reduce production time costs.

Description

technical field [0001] The invention relates to mixing and drying equipment for plastic particles, which belongs to the field of equipment manufacturing. Background technique [0002] Plastic particles, commonly known as plastic particles, are raw materials for storage, transportation and processing of plastics in the form of semi-finished products. Generally, for mixtures with very large water content or liquid content, such as paste, filter cake material, or sludge slurry material, or powder material mixed with liquid, or coal powder or mud with high water content, they Contains large amounts of moisture or liquid, making it difficult to transport or store them. Moreover, the production of leachate from a mixture with a very high water content or a very large liquid content will cause environmental pollution. Therefore, drying methods must be used to reduce the water content or liquid content. [0003] The working principle of the traditional conical mixing dryer is the...

Problems solved by technology

[0004] However, due to the limitation of the structure of the traditional internal spiral structure of the stirring shaft and the stirring paddle, or the use of a spiral stirring paddle for stirring, what is more, the position of the stirring paddle is changed to be biased towards both ends or off-centre vertically. Stir in the same direction. It has been proved by experiments that the stirring effect is not good, and the stirring speed is slow, which leads to the uniform mixing of materials and greatly increases the drying time, which reduces the production efficiency.
