Combined stand-alone grain fanner

Abstract

The invention discloses a combined stand-alone grain fanner. The combined stand-alone grain fanner comprises a lower steel frame, a heavy impurity removing device, a big and small impurity vibration removing device, a stone removing induced structure connected with the heavy impurity removing device, a dust collection induced structure connected with the big and small impurity vibration removing device, a material lifting system connected with the big and small impurity vibration removing device, a filtering dedusting structure connected to an exhaust outlet of the stone removing induced structure and an exhaust outlet of the dust collection induced structure, and a hopper used for providing unprocessed grain materials for the material lifting system. According to the combined stand-alone grain fanner, a material lifting fan is used for lifting the materials and providing the materials for cleaning devices, the effects of stably providing the materials for the cleaning devices can be achieved, and the situation that fluctuation in the material cleaning process is large and thus the cleaning effect is influenced is avoided; and the situation that the materials are frequently put into the combined stand-alone grain fanner manually can be avoided, and the production efficiency is improved. All the devices of the combined stand-alone grain fanner are connected in a sealed mode, and the interiors of all the cleaning devices are in the negative pressure state, so that the dust escape situation is avoided to a great extent.

Description

technical field [0001] The invention belongs to the technical field of grain processing machinery and equipment, and in particular relates to a combined single-machine grain cleaning machine. Background technique [0002] The combined stand-alone grain cleaning machine is a combined device used to remove large impurities, small impurities and large specific gravity impurities (stones and other impurities) and some light impurities contained in the raw grain. There are many defects in the existing relevant functional equipment: 1. The defect of the feeding method. When feeding the grain cleaning machine on the market, the raw grain is directly poured into the equipment manually, and then the cleaning operation is started. The convenience of this kind of feeding is poor. The operation characteristic of the grain cleaning machine is that the raw grain materials flow from top to bottom, and the large, small and heavy impurities are cleaned in sequence. The material operation is...

AI Technical Summary

Problems solved by technology

There are many defects in the existing related functional equipment: 1. The defect of the feeding method. When feeding the grain cleaning machine on the market, the raw grain is directly poured into the equipment manually, and then the cleaning operation is started.

The air volume on the screen surface of the blow-type de-stoner machine is not uniform. Due to the characteristics of the blower itself, blowing air at the lower part of the screen surface of the de-stoner machine can easily cause a large difference in the air volume distribution on the screen surface, and the materials on the screen surface cannot be balanced. Suspension requirements affect the effect of removing heavy impurities; the blowing destoner requires a large air volume, because the air volume distribution on the sieve surface of the destoner machine is uneven, and it is necessary to ensure a certain suspension speed for the raw grain materials on the entire sieve surface, so The air volume that needs to be provided is too large; the blowing stone removal machine is easy for dust to escape and pollute the environment. The internal air pressure of the blowing stone removal machine is greater than the external air pressure, which belongs to the positive pressure working state, so the dust generated inside the equipment is easily dispersed to the surrounding environment. In the air, dust pollution

3. At present, the grain cleaning machines on the market are basically open-type working conditions, with poor sealing performance, and the raw grain materials carry more dust and impurities, which will produce serious dust pollution during the operation of the equipment, and the used air will be damaged. Without filtering treatment, it is directly discharged into the atmosphere, polluting the environment
