AI Technical Summary
Technical Problem
The bearings of existing screw conveyors are susceptible to intrusion of external dust and impurities, leading to accelerated wear and affecting service life.
Method used
A screw conveyor with an air cylinder and annular air nozzle was designed. Dust is removed by blowing air into the bearing through a one-way valve and piston rod system, and dust is collected and treated by a filter screen to prevent it from re-entering.
Benefits of technology
It effectively removes dust and impurities from the bearing surface, reduces contaminant intrusion, extends bearing life, and improves dust collection efficiency.

Abstract
The utility model discloses an efficient and stable screw conveyer, and relates to the technical field of screw conveyors, the efficient and stable screw conveyer comprises a screw conveyer shell, one side of the screw conveyer shell is fixedly provided with a support frame, the top of the support frame is fixedly provided with a motor, the output end of the motor is fixedly provided with a rotating shaft, and the output end of the rotating shaft is fixedly provided with a screw rod. A bearing is fixedly installed on one side of the spiral conveyor shell, the rotating shaft is arranged in the bearing and extends into the spiral conveyor shell, an inflator pump is fixedly installed in the supporting frame, the bottom of the inflator pump communicates with a connecting hard pipe, and after gas enters the connecting hard pipe, the gas enters the connecting hard pipe, and then the gas enters the connecting hard pipe. When the bearing works, air is conveyed into the annular air nozzle through the connecting hard pipe, then the annular air nozzle blows air to the bearing, dust on the bearing is cleaned, foreign matter such as dust and chippings in the bearing and the surrounding environment can be removed through blowing, the risk that pollutants invade into the bearing is reduced, and the service life of the bearing is prolonged.
