Description

High-efficiency circulating air cylinder cleaning screen

technical field

The utility model relates to a mobile high-efficiency circulating air cylinder cleaning sieve for grain cleaning (impurity removal and dust removal).

Background technique

There is no circulating air cleaning system installed at the discharge port of the existing cylindrical cleaning screen. When the material layer in the discharge port is thick and unevenly distributed, the airflow blown by the fan cannot effectively separate the impurities in the discharge layer, and the impurity removal efficiency At the same time, the separated impurities are directly discharged without sedimentation treatment, causing great pollution to the surrounding working environment.

Utility model content

The purpose of the utility model is to provide a new circular air cylinder cleaning screen which overcomes the defects in the prior art, improves the impurity removal efficiency and reduces environmental pollution.

In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a high-efficiency circulating air cylinder cleaning screen, including a double-layer cylindrical screen with a feed inlet, an impurity outlet and a discharge outlet, which is rotatably arranged on the upper part of the frame and connected to the power The bottom surface of the discharge port is connected to the air outlet pipe of the fan, and the upper part of the discharge port corresponding to the bottom surface of the discharge port is connected to the separation chamber through the suction channel. The bottom of the separation chamber is provided with a settling chamber, and the separation chamber is connected to the fan through the return air pipe. .

A filter element is arranged in the middle of the separation chamber, and one end of the filter element communicates with the fan through the air return pipe.

There is a closed screw conveying mechanism at the bottom of the settling chamber.

The other end of the filter element in the separation chamber is provided with a regulating damper.

The working process of the utility model is as follows: the material (such as grain) enters the sieve in the rotating sieve body from the feed hopper, and gradually falls on the outer sieve under the continuous rotation of the rotating sieve, and the separated large impurities remain in the inner sieve. The dust and other small impurities are separated by the outer screen and discharged from the ash hopper. The material flows in the rotating sieve body and is finally discharged from the discharge port. When the material flows out from the discharge port, due to the difference in the suspension speed of light impurities and grain, the light impurities are carried up by the airflow blown by the fan, and enter the circulating air separation chamber through the vertical air duct. After the airflow is filtered by the filter element in the separation chamber, the airflow The impurities in the filter fall into the settling chamber and are continuously discharged by the closed screw conveying mechanism, and the filtered air returns to the fan through the return air pipe. So far, the entire circulating air system completes a cycle. The filter element and the circulating air separation chamber adopt an assembled structure, which is easy to disassemble, which is conducive to separating impurities in the air, cleaning up residual impurities, and ensuring the air flow back into the fan; one end of the filter element is equipped with an adjustable damper, which can be adjusted according to the processing capacity. The size assists in adjusting the air volume of the circulating air system to achieve the ideal impurity removal effect.

The utility model installs a circulating air cleaning system on the existing cylindrical cleaning sieve, which greatly improves the impurity removal efficiency of the equipment, reduces environmental pollution, and improves the working environment.
