Efficient combined sieve for wheat

Abstract

The invention relates to an efficient combined sieve for wheat. The efficient combined sieve for wheat comprises a machine frame (1) with a support (2); the support is connected with a sieve box (4); a set of sieve plates (5) are connected with the interior of the sieve box; the upper side of the sieve box is connected with a feeding hopper (11) through a buffer box (9); the support is connected with a centrifugal fan (12) and a dust catcher (15); an air inlet of the centrifugal fan is connected with the feeding hopper through a first pipeline (13); an air outlet of the centrifugal fan is connected with the dust catcher through a second pipeline (14). The machine frame is provided with a separator (16) correspondingly communicated with the sieve box and connected with the first pipeline through a third pipeline (17). The efficient combined sieve for wheat has the advantages that the sieve is used for removing impurities of wheat and grading the wheat; screens can be applied to grading various grains and oil plants after being replaced, and universality is good; wind generated by a fan of the cycle separator is recycled, so that electricity consumption is reduced greatly; the sieving efficiency of three layers of screens is improved than that of two layers of screens by 40%.

Description

technical field [0001] The invention relates to a filter device for grain, in particular to a high-efficiency combined sieve for wheat. Background technique [0002] Due to the different quantities of impurities contained in the wheat heap, the flour extraction rate varies greatly, and the apparent and internal quality of the produced flour also varies greatly. The wheat enters the warehouse and contains live insects, which leads to pests in the warehouse and loss of raw grain. Because of the above The reason is that there is a difference in the price of wheat. [0003] When purchasing wheat, strictly prevent illegal grain sellers from exchanging counterfeit goods, harming the reputation of the company, affecting product yield and quality, making up for defects in time, reducing risks, and removing large impurities in wheat, such as straw, and medium impurities, such as short straw Section; Small impurities, such as silt, dust, grass seeds, insects, etc., are separated to s...
