A wind-swept dynamic and static combined high-efficiency dust separator

Abstract

The invention discloses a wind sweeping type moving and motionless combination efficient separator. The wind sweeping type moving and motionless combination efficient separator mainly comprises an air outlet, an upper cover plate, an upper cylinder body, a cage type rotor, a middle cylinder body, a lower cylinder body, an inner cone, a medium dust discharging opening, a coarse dust discharging opening and an air inlet. The separator is characterized in that a motor and a transmission device are arranged on the upper cover plate, the cage type rotor is composed of a support, a main shaft, grading blades and the like, and is in key connection with the main shaft, transmission is achieved by the motor through a speed reducer, a fine dust grading chamber is formed between the outer ring of the cage type rotor and the guide blades, the inner cone is arranged on the lower portion of the fine dust grading chamber, a coarse dust grading area is formed by the inner cone and the middle cylinder body, the inner cone is connected to a lower cone through a fixed plate, and flexible adjusting and control over product fineness and grain fineness distribution can be achieved by utilizing a frequency changer.

Description

technical field [0001] The invention relates to a powder separation equipment in the fields of building materials, non-metallic minerals, non-ferrous metals, electric power, etc., specifically a wind-swept dynamic and static combined high-efficiency separator. Background technique [0002] Powder preparation is widely used in the fields of building materials, non-metallic minerals, and non-ferrous metals. At the same time, with the innovation and adjustment of modern sub-processes, the requirements for powder preparation and grading are getting higher and higher. For example, the particle size of cement circle grinding The sieve residue of 80 μm is generally required to be controlled below 1%, and the coal powder preparation system requires the fineness to be controlled below 12% of the sieve residue of 80 μm, and strict requirements are put forward for the uniformity of coal powder. same. In addition, in the existing cement mill system, after passing through the roller pre...
