[0002] Fly ash can be used as an important raw material for cement production. It can be processed into various types of cement: P, Pozz, PC, Slag, etc. Among these cements, Pozz cement is the most commonly used. It can not only reduce production costs, but also improve the comprehensive properties of hardened cement such as strength and impermeability.

[0003] Before fly ash is used in cement production, it needs to be screened by a powder classifier. In the prior art, due to the high humidity in the air, fly ash is easily damp and agglomerated. Most powder classifiers are unable to break up the agglomerated fly ash during use, which seriously affects the powder selection work. In addition, a large amount of fly ash will adhere to the inner wall of the powder classifier, which is inconvenient to clean and has insufficient practicality. Therefore, it is necessary to redesign a powder classifier for fly ash processing to address the above problems. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention.

The heater 6 is a semiconductor heater. Since the semiconductor heater uses semiconductor materials to generate heat, heat energy can be quickly generated in a short time after power is turned on, thereby achieving a rapid heating effect. This heating method also allows the heating temperature to be accurately controlled. The system can avoid problems such as overheating or too low a temperature causing poor heating effect. A connecting pipe 8 is rotatably installed inside the barrel 3. The connecting pipe 8 rotates and penetrates the leak plate 5. A motor 10 is fixedly installed on the outer wall of the upper hopper 4 through a supporting mechanism. The supporting mechanism includes a supporting plate 9 fixedly installed on the outer wall of the upper hopper 4. The motor 10 is fixedly installed on the bottom wall of the supporting plate 9. The outer wall of the output shaft of the motor 10 is connected to the connecting pipe 8 through a transmission mechanism. The transmission mechanism includes a pulley 11 fixedly installed on the connecting pipe 8 and the outer wall of the output shaft of the motor 10. The two pulleys 11 are connected and driven by belts.

Multiple stirring blades 16 are fixedly mounted on the outer walls of the two stirring shafts 13 through a connecting mechanism. The connecting mechanism includes a connecting sleeve 15 fixedly mounted on the outer wall of the stirring shaft 13, and each stirring blade 16 is fixedly mounted on the outer wall of the connecting sleeve 15. Multiple nozzles 17 connected to the interior are fixedly mounted on the outer wall of the connecting pipe 8, and each nozzle 17 is an anti-blocking nozzle, which can effectively prevent fly ash from clogging its spray hole. Two fixed sleeves 18 are fixedly mounted on the outer wall of the connecting pipe 8.

[0026] When the powder selection work is completed and a large amount of fly ash is attached to the inner wall of the machine barrel 3, the connecting pipe 8 can drive the two scrapers 20 to rotate in close contact with the inner wall of the machine barrel 3 through the cooperation of the fixed sleeve 18 and the fixed rod 19, so that the two scrapers 20 can clean the large amount of fly ash attached to the inner wall of the machine barrel 3. When it is necessary to clean the inner wall of the machine barrel 3, the water pump 21 can discharge the cleaning water into the connecting pipe 8 through the cooperation of its outlet pipe and the connecting sleeve 22. The cleaning water can be sprayed out through multiple nozzles 17 in the connecting pipe 8 and flush the inner wall of the machine barrel 3.
