Environment-friendly type composite grain scalping machine

Abstract

The invention discloses an environment-friendly type composite grain scalping machine. The environment-friendly type composite grain scalping machine comprises a multi-layer circular cylindrical screen, a negative pressure winnowing and dust removing device, an organic impurity processing device and a cloth bag dust removing device, wherein the cloth bag dust removing device comprises a draught fan and a cloth bag dust remover, the negative pressure winnowing and dust removing device is arranged on a grain inlet and a grain outlet, and a negative pressure wind pipe is connected with an inlet pipeline of the cloth bag dust remover. The environment-friendly type composite grain scalping machine has the advantages of being high in grain scalping efficiency, clean in cleaned grain, little in raised dust, environmentally friendly and the like, organic impurities can be removed, and the safety of grain which is put in storage is ensured.

Description

technical field [0001] The invention relates to the field of grain processing, in particular to an environment-friendly grain cleaning machine combining a sieve drum and winnowing. Background technique [0002] Food crops such as wheat, corn, and grains need to be cleaned before they are stored in the warehouse. Usually, the grain contains large debris such as stones and straws that are larger than grain particles, and small debris such as crushed stones and broken grains that are smaller than grain particles. In addition, there are dust and organic impurities or light impurities that are basically the same size as grain particles, but lighter in weight, such as moldy grain particles, insect-eaten grain particles, etc. The above-mentioned impurities are removed from the raw materials by a cleaning machine to obtain clean finished grains, which is convenient for subsequent processing, and can also prevent hidden dangers such as flammable grains, grain mildew, and insects duri...

AI Technical Summary

Problems solved by technology

[0004] The problem with this cleaning method is that it adopts a single sieve drum cleaning method, and the removal of dust is not thorough enough. In addition, small impurities and dust are directly discharged into the air, which is easy to cause dust and cause environmental pollution.

In the follow-up improvement technology, there are also other equipments that adopt the compound cleaning method combining screen cylinder and winnowing. Reasonable, resulting in poor dust removal effect, and easy to cause greater environmental pollution

In addition, it is difficult to remove organic light impurities that are the same size as grain particles but have a lighter specific gravity, which brings hidden dangers to grain storage.
