Environment-protecting grain cleaning and dust removing device

Abstract

The invention discloses an environment-protecting grain vibration dust removing device. The device comprises a base and a dust removing device body, wherein a screen body support is arranged at the right end of the base, a double-layer vibration screen is obliquely arranged on the screen body support, a grain outlet and an impurity outlet are formed in the lower end of the double-layer vibration screen, the dust removing device body is arranged on the left side of the double-layer vibration screen, the dust removing device body comprises a bag-type dust remover arranged at the left end of thebase and an air inlet cylinder arranged above the grain outlet, the upper end of the air inlet cylinder is connected with an air suction pipe, and the air suction pipe communicates with an air inlet of the bag-type dust remover. The device has the advantages of being simple in structure, practical and convenient, suitable for grain cleaning and impurity removal equipment, rapid and stable in dustremoval, good in dust removal effect, and clean and environment-protecting in dust removal process.

Description

Technical field: [0001] The invention relates to the field of grain production equipment, in particular to an environmentally friendly grain cleaning and dust removal device. Background technique: [0002] Grain harvested by combined harvesting machinery will inevitably contain a lot of impurities such as straw. Therefore, before subsequent processing or storage of the grain, the grain needs to be cleaned and removed. In the grain storage warehouse, in order to facilitate the transportation and installation of storage equipment The portability, high efficiency and environmental protection of storage equipment have attracted more and more attention. When the grain storage warehouse stores grain, there are certain requirements for the impurity content of the grain. Therefore, it is necessary to use a grain storage cleaning center or grain before storing grain. Storage equipment removes impurities from food. Most of the cleaning processes require operations such as vibration, screen...

AI Technical Summary

Problems solved by technology

[0002] The grain harvested by the combine harvesting machine will inevitably contain a large amount of impurities such as straw. Therefore, before the subsequent processing or storage of the grain, it is necessary to clean the grain, remove dust and remove impurities. In the grain reserve, in order to facilitate the transportation and installation of storage equipment And mobile, the portability, high efficiency and environmental protection of storage equipment are getting more and more attention. When storing grain in the grain reserve, there are certain requirements for the impurity content of the grain. Therefore, it is necessary to use the grain storage cleaning center or grain storage before storing grain The storage equipment removes impurities from the grain. Most of the removal process requires vibration, screening, transmission and other operations. In this way, the dust and light impurities contained in the grain will fly up, resulting in serious dust in the working environment, polluting the environment and harming the operators. The health of the respiratory tract is harmful. In the current technology, the dust removal effect during the impurity removal process is poor, and there is a lack of dust collectors for grain removal equipment for grain storage.
