The material moves along the inclined direction of the chute under the push of the air, and performs continuous reciprocating motion with the airflow, thereby achieving efficient and continuous material conveying; when the existing cement chute conveying equipment encounters problems of blockage and material leakage caused by debris in the material during efficient conveying, it is necessary to stop the upstream material conveying equipment, but the existing air chute conveying equipment requires the operator in the central control room to find that the current of the chute fan or downstream equipment is abnormally higher than the normal value before manually stopping the upstream material conveying equipment. It is cumbersome to use and takes a long time to operate. It is not convenient to remind the operator in the central control room of the problem of blockage and leakage in time, which makes it easy for a large amount of blockage and leakage to occur, which in turn easily causes environmental incidents and requires a lot of manual cleaning of leakage; for this reason, it is necessary to provide a cement chute with an additional temperature measuring device to solve the above problems.
