Description

High performance centrifugal separator
Technical field
The utility model relates to a kind of high performance centrifugal separator, it can be widely used in wheat flour milling, grain processing and ore pulverizing etc. are many to need to separate in the industry of comminuting matters that quality and granular size do not wait raw material after grinding, and also can be used for the light impurity of Powdered and other shape of mixing in the eliminating particle shape material.
Background technology
Whizzer is that a kind of centrifugal force of swirling eddy that utilizes blows to airborne solid particle on column type or the pyramid type chamber wall, and solid particle is slided to reach a kind of machine of separation of material purpose along barrel.Whizzer has simple in structure, and cost price is cheap, and is widely applicable, uses advantages such as easy to maintenance.Many at home and abroad industries all are widely used.Yet existing common whizzer is depended merely on centrifugal force and is separated big heavier material efficient height, and it is low to separate less lighter material efficient, difficulty is big, and the material size particles of separating do not wait mixed in togetherly, can not adapt to many special requirements of industries.
Summary of the invention
The purpose of this utility model provides a kind of energy can isolate the simple in structure of three kinds of materials that weight, granular size do not wait simultaneously, use easy to maintenance, the high performance centrifugal separator that cost price is cheap
The purpose of this utility model is to install the screen cloth tube additional by the exhaust duct lower end at existing whizzer, increases the powered brush mechanism that is made up of hairbrush, brush holder, gear-box, power transmission shaft and reductor and the feeding distribution mechanism be made up of broach hopper, hollow shaft, pipe, inner conical-tube, internal partition and external partition and impeller feed valve with three chamber impellers realize.
The utility model is because installed the screen cloth tube in former whizzer exhaust duct lower end, outside the screen cloth tube, increase by hairbrush, brush holder, gear-box, the powered brush mechanism that power transmission shaft and reductor are formed, below the screen cloth tube, increased by broach hopper, hollow shaft, pipe, inner conical-tube, internal partition, feeding distribution mechanism and an impeller feed valve with the external partition composition with three chamber impellers, so can make big heavier material particles because the separated circular passage that falls between inner conical-tube and the urceolus of centrifugal principle, and discharge entered the right-side cavity of impeller feed valve by the external partition guiding after; Lighter medium grain material is blocked in the outer back of screen cloth and is fallen endosiphuncular tube by the hairbrush brush, and discharges entered the chamber, left side of impeller feed valve by the internal partition guiding after; And the big heavier granule material of the part of passing opening of sieve is because the gravity effect is fallen the broach hopper of screen tube bottom again by discharging after the intermediate cavity that enters the impeller feed valve behind hollow shaft and the pipe; Promptly reach the separation purpose.The utility model just carries out simple and easy improvement to existing common whizzer and promptly reaches and isolate weight simultaneously, the purpose of three kinds of materials that granular size does not wait, and because the mesh size that increases can reduce as required, make the utility model can be easier to realize the separation of fine particle material that existing common whizzer is difficult to separate, this is with practical value in many industry production, particularly industry such as the wheat flour milling of frivolous skin shape material being separated separately at need and other grain processing has the advantage that common sieve method can't be compared, its application prospect is extensive, remarkable in economical benefits.
