Uniform material distributing device and method adaptable to various kinds of materials

Abstract

The uniform distribution device and method that can adapt to various materials of the present invention include: a screw shaft, the screw shaft is a hollow shaft, the inner space of which forms a cooling water cavity, and the outer side of the screw shaft is provided with right-handed helical blades along the axial direction A group and a left-handed helical blade group, the right-handed helical blade group extends from the dividing line to one end of the screw shaft, the left-handed helical blade group extends from the dividing line to the other end of the helical shaft, directly connected to the geared motor, The direct-coupled geared motor is connected to the screw shaft to drive the screw shaft to rotate. Bearing seats are arranged at both ends of the screw shaft for supporting the screw shaft. The uniform material distributing device and method provided by the present invention have a built-in cooling function and a sealing device isolated from the outside air, and can realize continuous, uniform, and equal-thickness material distribution in a high-temperature environment.

Description

Technical field [0001] The invention relates to a distributing device and method that can adapt to various types of materials, and has a wide application field, and can realize continuous, uniform and uniform thickness distributing of various materials. Background technique [0002] In the technical fields of iron and steel metallurgy, chemical industry, etc., many occasions involve uniform cloth, otherwise it will have an adverse effect on subsequent production. For example, in the field of steel reduction technology, if uniform distribution is not achieved, it will cause uneven heating of materials, which will affect the reduction quality of materials and lead to low productivity; in technical fields such as pyrolysis, if uniform distribution is not achieved, materials will be damaged. The uneven heating will affect the pyrolysis of the material. In severe cases, the pyrolysis of the material will fail and the raw meal will appear. [0003] In the prior art, a scraper is used to...

AI Technical Summary

Problems solved by technology

For example, in the field of iron and steel reduction technology, if uniform distribution cannot be achieved, the material will be heated unevenly, which will affect the reduction quality of the material and lead to low productivity; Uneven heating will affect the pyrolysis of materials. In severe cases, the pyrolysis of materials will fail and raw materials will appear.

[0003] In the prior art, a scraper is used to make the cloth uniform. This method has the following defects: 1. The scraper is variable in a high temperature environment, which affects the uniformity of the cloth and has a short service life; 2. The scraper type cloth device cannot be realized. Uniform material distribution after changing the pan speed

However, the scraper type material distribution device has relatively high requirements for materials and poor adaptability. It is effective for powdery and granular materials, but it is easy to accumulate and agglomerate for materials containing flexible materials, which cannot achieve uniform distribution.

[0004] The uniform material distribution device in the prior art has poor adaptability to the state of the material, is not suitable for an environment where the speed of the material tray is adjustable, and has poor high temperature resistance and short service life
