Background technique

Soybean is the raw material for the production of edible vegetable oil. Soybean can also be processed into non-staple food. Soybean is rich in various minerals, vitamins and other nutrients. Therefore, soybean is a very important food and economic crop.

After the soybeans are harvested, a series of post-processing is required, such as drying, beating, bagging, etc. Before bagging, pneumatic conveying, sorting soybeans and straw, screening sediment, and dry purification are of great importance to improve the quality of soybeans. It is particularly important, and it is also an essential process to support the industrial processing of soybeans.

At present, there is no device specially designed for pneumatic conveying and sorting of soybeans after harvesting, drying, and beating on the market. The lack of existing technologies has seriously restricted the development of the soybean industry.

When the sorting device is working, the soybeans and straws that have been dried and beaten are screened through the vibrating feeder, and the large straws fall into the straw barrel, and the screened materials enter the hopper, and enter the pneumatic separation through the material leakage gate. There is a rising main sorting airflow in the sorting tube. When soybeans and light impurities fall from the material door and approach the silicone blade cyclone distributor, the light impurities have a lot of opportunities to be pumped through the pipeline by pneumatic force. The silicone cyclone distributor is controlled by the distributor shaft. Composed of silicone blades, the rising main airflow will cause the silicone blade cyclone distributor to rotate at a certain speed, so that the soft silicone blades are conducive to breaking up the agglomerated soybeans and shells without damaging the soybeans, further realizing the purification of shelled soybeans, and wearing After passing through the silicone blade cyclone distributor, the soybeans roll down on the inclined sieve plate. The sediment and small stones with poor rolling properties will pass through the sieve and fall into the sediment bucket for temporary storage. The clean soybeans screened by the vibrating screen fall into the soybean material bucket for temporary storage. , large particles of stones and sediment will fall into the stone bucket for temporary storage.

The pipeline guides the light impurities into the cyclone separator tangentially, and the screen drum can prevent the light and larger impurities from being carried out by the air flow again. The fan is used as the power, and the purified exhaust gas is discharged from the exhaust pipe.

The air lock realizes that the impurity output falls into the light impurity barrel for temporary storage under the condition of gas pressure difference.

Compared with the prior art, the utility model has the beneficial effects of:

The separation effect is good and it is convenient for continuous operation; the silica gel cyclone distributor has the function of dispersing materials, which is beneficial to air separation and has a significant secondary purification and dispersion effect; the sieve drum is installed in the cyclone separator to separate materials quickly and efficiently, which is different from traditional Compared with the cyclone separator, the height of the equipment is reduced, which is beneficial to the layout of the equipment.

The utility model has strong practicability, is beneficial to the implementation of soybean industrialization, and has broad application prospects.
