A safe and environment-friendly powder concentrator sealing device

Abstract

The invention discloses a safe and environment-friendly powder separator sealing device, which includes a driving motor, and is characterized in that: a main shaft is socketed under the driving motor, and a case cover of a powder selection machine is arranged on the outer side of the main shaft, and the main shaft A sealing screening device and an interface sealing device are provided on the outer side of the shaft. The sealing screening device includes a housing welded and installed under the cover of the powder classifier. The gap between them is a fine powder channel, the first spiral sleeve is fixedly installed above the sieve plate, the outer side of the first spiral sleeve is provided with double-layer external threads, and the inside of the housing is provided with double-layer screw sleeves. The first spiral sleeve is meshed with the housing, and the two sides above the first spiral sleeve are correspondingly provided with air outlet pipes. The first spiral sleeve is a magnetic sleeve. The present invention has No clogging and high sealing characteristics.

Description

technical field [0001] The invention relates to the technical field of powder separators, in particular to a safe and environment-friendly sealing device for powder separators. Background technique [0002] There are many types of powder separators, and different types are suitable for different materials. Different models are also produced according to customer requirements for material fineness. Generally, the common powder separators include cyclone type cyclone powder separator, three-separation powder separator, centrifugal powder separator, special separator for coal mill, special separator for calcium powder, etc. Later, many high-efficiency powder separators and high-efficiency three-separation powder separators were developed. They are new-generation varieties that improve on the original basis and increase production. [0003] However, the existing sealing device of the powder classifier is easy to cause blockage during powder selection and has poor practicability...

AI Technical Summary

Problems solved by technology

[0003] However, the existing sealing device of powder classifier is easy to cause blockage during powder selection, and the practicability is poor. At the same time, when the fine powder of the existing sealing device of powder classifier is inhaled, it will cause a large impact on the interface of the storage box, thereby causing wear to the interface sealing device.
