Grain winnowing and stone and impurity removing separator

Abstract

The invention relates to a grain winnowing and stone and impurity removing separator. The separator comprises a frame, an air supply system, and a storage box and a winnowing separation box which are arranged on the frame, wherein a vibrating feeding plate which is inclined downwards is arranged below the discharge port of the storage box; a vibrating motor is arranged at the bottom of the vibrating feeding plate; the top of the vibrating feeding plate is hinged to the frame; the bottom of the lower blanking end of the vibrating feeding plate is connected with a compression spring; the compression spring is arranged on the frame through a spring seat; the blanking end of the vibrating feeding plate is opposite to the feed port of the winnowing separation box; the air supply system comprises a fan and an air supply channel; the air outlet of the air supply channel is communicated with the feed side of the winnowing separation box; a heavy impurity discharge port, a grain discharge port and a light impurity discharge port are sequentially formed at the bottom of the winnowing separation box along the air inlet direction; an air closer is arranged at the light impurity discharge port; an exhaust regulating port is formed on the top of the winnowing separation box; and a cloth filter bag is arranged in the exhaust regulating port. The separator has a reasonable structure and is obvious in separation effect and high in material treatment capacity, and the material cleaning range is wide under the action of air.

Description

technical field [0001] The invention relates to a grain winnowing separator for stone removal and impurity removal, which belongs to grain separation and cleaning and impurity removal equipment. Background technique [0002] At present, domestic large-scale starch factories, monosodium glutamate factories, feed factories, edible oil factories, alcohol factories and other grain processing capacity of 50-200 tons or more all use drum cleaning sieves. The drum type cleaning sieve is characterized by simple structure, low failure rate, low power and low cost, so it is widely used, but it uses the method of sieve filtration to achieve the cleaning effect. The impurities in the grain are mainly divided into large impurities, medium Impurities and small impurities, large impurities mainly include straw, bricks, large corn cobs, plastic packaging bags, ropes, etc., medium impurities mainly include gravel, small corn cobs, metal blocks, etc., and small impurities mainly include sand ...

Problems solved by technology

The drum type cleaning sieve is characterized by simple structure, low failure rate, low power and low cost, so it is widely used, but it uses the method of sieve filtration to achieve the cleaning effect. The impurities in the grain are mainly divided into large impurities, medium Impurities and small impurities, large impurities mainly include straw, bricks, large corn cobs, plastic packaging bags, ropes, etc., medium impurities mainly include gravel, small corn cobs, metal blocks, etc., and small impurities mainly include sand corn cobs Flour, chaff, bran dust, etc., and this method of sieving can only remove part of the large and small impurities, but cannot remove side-by-side impurities (impurities that are as large as the sieve hole) and some light impurities. Therefore, the effect of separation and impurity removal is not good. At present, the method of air separation cleaning and impurity removal has been proposed through research. Wind separation cleaning and grain grading are also an effective method that is widely used at present. Vibration air selection screens, Square suction separator, circulating air vertical separator

The vibrating wind screen is mainly used for wheat seed selection and cleaning; the square suction separator is mainly used for corn cleaning, but it is rarely used because the effect is not ideal; the circulating air vertical separator is produced by Buhler, Switzerland , it is characterized by the use of circulating air to make the equipment consume less power. It is currently more advanced and used more equipment, but there are also shortcomings, namely: due to the limited structure, the feeding port is concentrated and the output is increased. In the future, the cleaning effect of impurities will be very poor, and the impurities with larger specific gravity will not be able to be dealt with.

These types of equipment are all complex in structure, low in efficiency and small in output, and have certain limitations in cleaning effect, and the processing capacity is small

At present, there is no manufacturer producing equipment with a large amount of wind separation and impurity removal.
