A raw material impurity removal and screening device for grain and oil processing

Abstract

The invention relates to a raw material impurity removal and screening device for grain and oil processing, which belongs to the technical field of grain and oil processing equipment. Partition plate, the second partition plate, the side of the first partition plate near the discharge port, the side of the first partition plate near the discharge port forms the first impurity removal chamber; the first partition plate and the second partition plate A second impurity removal chamber is formed between them; a number of first discharge ports are arranged at intervals in the circumferential direction of the first partition; the first discharge port communicates with the second impurity removal chamber; A stirring mechanism for stirring the raw materials on the upper side of the first partition; a blowing mechanism for blowing air into the first impurity removal chamber and / or the second impurity removal chamber is arranged in the box; a suction mechanism is arranged outside the box , the suction mechanism sucks the air in the box. By adopting the above technical scheme, light and fine impurities in raw materials can be removed under closed conditions.

Description

technical field [0001] The invention belongs to the technical field of grain and oil processing equipment, and in particular relates to a device for removing and screening raw material impurities for grain and oil processing. Background technique [0002] The products harvested by the planting industry are collectively referred to as agricultural products, including grain, cotton, oil, fruit, vegetables, sugar, tobacco, tea, fungi, flowers, medicines, and miscellaneous. The basis of survival, agricultural products in a narrow sense generally refer to oil and grain raw materials. The raw materials of oil and grain are mainly the grains of crops, and also include plant rhizomes rich in starch and protein, such as rice, wheat, corn, soybean, peanut, rapeseed, sweet potato, potato, etc. [0003] There are many impurities in raw materials, such as heavy impurities such as stones and metals. When they enter the machine for processing, the impurities will damage the machine to a c...

AI Technical Summary

Problems solved by technology

[0003] There are many impurities in the raw materials, such as heavy impurities such as stones and metals. When entering the machine for processing, the impurities will damage the machine to a certain extent after entering the machine, affecting the safety and normal wages of the equipment.

Or light and soft impurities, such as rope ends, cloth pieces, straw, weeds, paper scraps, etc., will block the feeding mechanism when they enter the machine for processing, causing uneven feeding, reducing the feeding speed, and reducing the equipment process. effect, affecting equipment efficiency

Or small impurities such as silt and dust will easily cause dust to fly and pollute the environment after being brought into the workshop

[0004] In the prior art, when removing light and soft impurities and fine impurities, generally an open site is selected to remove light and fine impurities by winnowing. Although this method is common and simple, in the process of removing , has greatly affected the surrounding environment, and the working environment is extremely bad
