Description

A kind of combination type grain cleaning sieve
Technical field
This utility model relates to grain cleaning sieve technical field, particularly relates to a kind of combination type grain cleaning sieve.
Background technology
Along with grain, edible oil processing and the development of foodstuff preservation industry and technological progress, the cleaning quality to grain It is proposed higher requirement with unit interval treating capacity.Grain needs to carry out remove impurity before warehouse-in stores, and removes in grain Leaf, bran shell, the foreign material such as dust and flat grain, improve grain cleanliness factor, improve grain quality, it is simple to the storage of grain, it is to avoid grain Go bad due to foreign material, ensure the shelf-life of grain.Existing grain impurity removing device generally uses grain cleaning sieve, utilizes vibration Sieve carries out screening cleaning to grain, can produce substantial amounts of ash dust and gas along with the grain being sieving through together during screening cleaning Discharge, affect the cleanliness factor of grain, the most also pollute the environment, affect the healthy of staff.Existing grain is cleared up Sieve cannot effectively remove the impurity in raw grain, and the most miscellaneous and dust is difficult to separate from grain and settle, and grain percentage of impurity is high, grain Dust from flying in scale removal process, air pollution is serious.
Utility model content
The technical assignment of technical problem to be solved in the utility model and proposition is to improve prior art, it is provided that A kind of combination type grain cleaning sieve, solves the clear miscellaneous weak effect of grain cleaning sieve traditional in current technology, it is difficult to by impurity from grain Removing in food, grain percentage of impurity is high, course of processing dust from flying, the problem that air pollution is big.
For solving above technical problem, the technical solution of the utility model is:
A kind of combination type grain cleaning sieve, including frame, feed arrangement, screening body and dust arrester, it is characterised in that Described screening body is tilting gearing vibrosieve in frame, and the top of screening body offers charging aperture, on charging aperture Being connected to feed arrangement, the bottom of screening body is provided with impurities outlet and grain-export, and grain-export is provided with dedusting dress Putting, dust arrester includes blower fan and dedusting separating mechanism, and the air inlet of described blower fan is provided with dust absorbing air passage, dust absorbing air passage Covering at the grain-export of screening body, the air outlet of blower fan and the entrance of dedusting separating mechanism are direct-connected by flange arrangement, remove The outlet of dirt separating mechanism is connected with discharge with endless screw pipe.Combination type grain cleaning sieve described in the utility model uses high-performance big Area gravitational settling makes grain and weighs miscellaneous efficiently separating, and then utilizes blower fan directly by the grain of vibrosieve grain exit Lightweight and dust siphon away, and improve the cleanliness factor of grain, the most miscellaneous individually separate with dust and settle, and lightweight and dust are via wind Machine directly blasts dedusting separating mechanism and carries out dust removal operation, falls in discharge with endless screw pipe and be pushed out after dust impurity sedimentation, raw grain In impurity repeatedly cleared up, realize under the conditions of low power consuming by raw grain impurity reduce.This utility model simple in construction is tight Gather, can effectively reduce windage, thus the power of fan needed for reducing, the effectively save energy, without parts such as unnecessary adapting pipes, Thus without dead angle, it is not necessary to often clearing up, it is more convenient to use, and ensures production efficiency, can be prevented effectively from appearance in operation process The situation of dust from flying, reduces air pollution, improves working environment quality, and safeguard work personnel's is healthy.
