Biaxial multi-channel coarse powder separator

Abstract

The invention discloses a biaxial multi-channel coarse powder separator. The biaxial multi-channel coarse powder separator comprises a feed pipe; the top of a return pipe is fixedly connected with anouter cone; the side, far from the outer cone, of a wear resisting plate is fixedly connected with a wear resisting bushing; the end, far from the outer cone, of a support rod is fixedly connected with an inner cone; the inner wall of a cylindrical outer shell is fixedly connected with a separation middle layer through locking bolts; the surface of a first rotating shaft is fixedly connected witha first guide baffle plate between the inner cone and the separation middle layer; the surface of a second rotating shaft is fixedly connected with a second guide baffle plate between the separation middle layer and the cylindrical outer shell; locking devices are arranged on the outer surface of the cylindrical outer shell and positioned on the first rotating shaft and the second rotating shaft;and the biaxial multi-channel coarse powder separator relates to the technical field of pulverized coal separation. The biaxial multi-channel coarse powder separator achieves the effects of multiple channels, multiple times of separation and locking, is simple in structure and convenient to use, saves both time and power, prevents random rotation, improves the separation effect, and improves the working efficiency.

Description

technical field [0001] The invention relates to the technical field of coal powder separation, in particular to a biaxial multi-channel coarse powder separator. Background technique [0002] Coarse powder separator is an important equipment in the milling system. Its main function is to separate the qualified fine powder and return the unqualified coarse powder to the mill for regrinding. It is widely used in power plants, cement industry, chemical industry and metallurgical industry. The height and volume of the directional type coarse powder separator are greatly increased, and the airflow stroke in the separator is more reasonable than that of the radial type. The axial coarse powder separator is more widely used in the industrial separation process. The coarse powder separator is a thermal power plant One of the key equipment of the coal powder preparation system, its function is to separate the coal powder ground by the coal mill according to the particle size. At pres...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a biaxial multi-channel coarse powder separator, which solves the problem of complex structure, inconvenient use, inability to flexibly use, inability to realize multi-channel, multiple separations, poor separation effect and time-consuming Laborious, low work efficiency, and inconvenient adjustment of the diversion baffle, without automatic locking design, it is easy to rotate randomly with the wind direction, affecting the analysis efficiency, and the inner wall is severely worn, and powder leakage often occurs, causing serious economic losses.
