Wheat washer capable of feeding from bottom

Abstract

The method relates to a wheat washer capable of feeding from the bottom. The wheat washer comprises a sand removing device 1, and a dry tower 2 and a timing spray system 3 connected with the sand removing device 1, wherein the sand removing device includes a circulating water box casing 1-1, a sand packing auger 1-2, a wheat packing auger 1-3, and a transmission box 1-4 used for driving the sand packing auger 1-2 and the wheat packing auger 1-3. The minimum water adding rate of the wheat washer capable of feeding from the bottom is 2 to 3%. The wheat washer can still meet the process requirement when the water content of wheat grain is higher or in damp summer. The water consumption is 500 to 700 kg, the water saving effect is remarkable, and meanwhile, sewage discharge is reduced. In the invention, a sealed and downwardly-inclined square back water tank is adopted to effectively eliminate sewage foam and keep working environment clean and sanitary. In the invention, the timing spray system is designed, and the water adding quantity is adjusted accurately to meet the flour milling technology requirement according to the indication of a rotameter when water needs to be added. The invention changes the conventional way of direct feeding of a wheat washer into the way of feeding from the bottom of a base of the wheat washer, enables wheat to quickly enter into the drying tower to be dried and discharged along a pipeline at the lower part of the base under the combined action of negative pressure generated in rotation of the drying tower and a feeding and jetting device, so that the defect that the primary water adding rate of the wheat washer is too large is eliminated.

Description

[0001] technical field [0002] The invention relates to a bottom feeding wheat washing machine. Background technique [0003] Wheat washing machine is one of the main cleaning equipment commonly used in flour processing factories. Its main functions are: to clean the dust and pesticide residues on the surface of wheat, and to remove sand and stone impurities in wheat by using the principle of specific gravity, so as to ensure the cleanliness of wheat into the mill. Reduce the ash and sand content of flour and improve the precision of flour. The water tank and the wheat washing tank of the currently widely used wheat washing machine are connected to the drying tower. It is difficult to control the water content of the wheat washing machine. The water content is 3-5%. When the moisture content of the raw wheat grain is high, or in the wet season of summer, the water content of the traditional wheat washing machine will exceed the national standard for flour safety moistu...

AI Technical Summary

Problems solved by technology

The water tank and the wheat washing tank of the currently widely used wheat washing machine are connected to the drying tower. It is difficult to control the water content of the wheat washing machine. The water content is 3-5%. When the moisture content of the raw wheat grain is high, or in the wet season of summer, the water content of the traditional wheat washing machine will exceed the national standard for flour safety moisture, and the flour moisture quality index is unqualified; and the traditional wheat washing machine The water consumption per ton of wheat of the machine is 800-1000kg, which is serious waste water and also increases the discharge of sewage

When the existing traditional wheat washing machine is running, due to the dust and organic impurities in the wheat, a large amount of foam is generated. In severe cases, the entire wheat washing machine will be covered, and the sewage will overflow, causing serious pollution around the wheat washing machine.

It does not meet the production environment requirements of the flour mill; the spray system of the traditional wheat washing machine is manually controlled spray, which is easy to forget, and the spray is not timely, resulting in unstable water flow
