According to the device, the characteristic that the weights of grains and impurities in a raw material are different is used, the cyclone dust removing principle is adopted for performing air separation and machining before the grains are machined, as the fan for making circulation air flow inside the separation device is mounted at the bottom of the device, circulation turnover of the raw material is effectively formed, and the air separation efficiency is further improved as the air ejection hole matched with the circulation air flow is formed near the spiral raw material inlet.
Description
Technical field
The utility model belongs to food processing machinery design field, especially belongs to a kind of grain impurity-removing separator.
Background technology
Before carrying out extensive grain processing, need raw food to carry out removal of impurities separation, if common selection by winnowing is exactly to utilize air-flow that the impurity of the different quality in grain raw material is separated.Cyclone dust collectors are in industrial production, to be applied to discharge fume the device of dedusting, and it can be separated by the solid waste in industrial waste gas.Its application of principle is had to different constructional devices in the removal of impurities separation of grain raw material, but how further to raise the efficiency, realize further separation, Cereals Processing Machines industry is being made unremitting effort always.
Summary of the invention
The utility model discloses a kind of grain impurity-removing separator.Problem to be solved in the utility model is to provide a kind of efficiency grain impurity-removing separator higher, that structure is more succinct.
The utility model is achieved through the following technical solutions:
Grain impurity-removing separator, consists of the cylindrical drum of hollow, it is characterized in that: described cylindrical drum is increased gradually by bottom to upper diameter; End cap is arranged at cylindrical drum top, and end cap center has evacuated tube to be communicated with extractor fan; Cylindrical drum top has spirality feed(raw material)inlet is tangentially set; Cylinder barrel, with same level position, feed(raw material)inlet be provided with air port; Top, cylindrical drum bottom is provided with the upwards blower fan of air blast.
Axially radially arranging along cylindrical drum of described air port.
The axial line of described air port and feed(raw material)inlet Grain lines included angle B are 90 degree.
When the removal of impurities of carrying out grain raw material is separated, open the air blast blower fan of separation unit bottoms top and the extractor fan that top evacuated tube is communicated with, the circulating current that formation center makes progress in device cylindrical drum, raw food send mode to send into along tangent line from spirality feed(raw material)inlet by wind, when raw food passes through air port, affected by air port uprush, in raw material, compared with the separated Bing Sui of light impurity center updraft, discharge, raw food continues to fall with spiral way, is subject to circulating current effect to realize further impurity separated.
The utility model helpfulness: the utility model utilizes the raw material grain characteristic different from impurity quality, adopts cyclone dust removal principle to carry out the separated processing of selection by winnowing before grain processing; Device installs in bottom the circulating current arranging in air blast manufacture separator, has effectively formed the circulation boiling of raw material, air port is set in spirality feed(raw material)inlet and coordinates circulating current further to improve the efficiency of selection by winnowing separation.The utility model device separative efficiency is high, simple for structure, is specially adapted to the separation of light impurities in grain raw material.
