Description

A kind of double type impurity removal and environmental protection grain cleaning machine

technical field

The utility model relates to a grain machine, in particular to a duplex impurity removal and environmental protection grain cleaning machine.

Background technique

Grain needs to be sieved to remove impurities before processing, so as to effectively classify and screen the foreign matter and shriveled grain in the grain. In the process of grain screening, dust will inevitably be generated, which will cause health hazards to employees in the working environment and cause pollution to the environment. The existing grain screening machinery includes a wind-selecting drum vibration initial cleaning machine with the announcement number of CN207025851U. Although the main dust-laden air is beneficial to the wind separation device for a certain degree of recycling, it is inevitable that the dust-laden air overflows, causing particulate pollution in the air, and the air-selected bran is relatively scattered and scattered in the air-selector. The outside of the device is not easy to collect, resulting in environmental pollution and waste of resources. With people's attention to health and environmental pollution issues, the market needs a grain screening and impurity removal device with better dust removal effect and higher resource utilization efficiency.

SUMMARY OF THE INVENTION

The utility model provides a double-type impurity-removing and environment-friendly grain cleaning machine which avoids dust overflow, realizes continuous dust removal without stopping the machine, and sorts, collects and compacts bran.

The utility model relates to a double-type impurity-removing and environment-friendly grain cleaning machine, which comprises a casing, an air separation device, and the dust removal device; the casing is provided with a trommel screen, and the casing below the trommel screen is provided with a receiving device. The vibrating screen of the trommel sieve is connected to the air separation device at the grain outlet of the vibrating screen, and the air outlet of the air separation device is connected to the dust removal device through the pipeline; the air separation device is a negative pressure bran remover, and the negative pressure bran remover The air outlet of the negative pressure generating device is connected to the dust removal device through a pipeline.

Preferably, the dust removal device is a pulse bag filter.

Preferably, the vibrating screen is a double-layer vibrating screen, the oversize of the upper vibrating screen is discharged out of the casing together with the oversize of the trommel screen, and the undersize of the lower vibrating screen is discharged from the casing through the collecting cylinder.

Preferably, spiral blades are arranged in the drum screen, and the blades are used to disperse grains with large straws so as to remove large impurities more effectively.

Preferably, the grain outlet of the vibrating screen is connected with the air separation device through a sealed pipeline, so that the entire casing can be in a negative pressure state through the air extraction of the air separation device, so as to avoid dust spillage.

Compared with the prior art, the multi-type impurity-removing and environmental-friendly grain cleaning machine described in the utility model uses the negative-pressure bran removing machine to realize the sorting, collecting and compacting of bran and the negative pressure in the casing to reduce dust overflow. Improve resource utilization efficiency; connect the pulse bag filter to the air outlet of the negative pressure bran removal machine to achieve continuous dust removal without stopping, improve work efficiency and dust removal effect.
