Stirring and screening device and flour mill

Abstract

The invention provides a stirring and screening device, which comprises a base 6, a discharging barrel 3, a stirring tank 1 and a vibration source 2. Upright posts 18 are arranged on the base 6, and a flat plate 19 is arranged above the base 6; the stirring tank 1 is provided with a middle flange 27, and the middle flange 27 is movably connected with the upright posts 18; the inner cavity of the stirring tank 1 is communicated with the top of the discharging barrel 3, and a screen 22 and a plugging plate 23 capable of being opened and closed are arranged on a bottom outlet of the inner cavity; the vibration source 2 is fixedly arranged on the middle flange 27 of the stirring tank 1; and springs 20 are arranged on four sides of the stirring tank 1, the bottoms of the springs 20 are fixedly connected with the flat plate 19, and the tops of the springs 20 are fixedly connected with the middle flange 27. The invention also provides a flour mill. Through the stirring and screening device and the flour mill, multiple procedures can be continuously finished at one time, contact between a material and air or a person is avoided, high purity and quality stability of the material are ensured, and the loss of the material is greatly reduced.

Description

technical field [0001] The invention belongs to the field of powder preparation, and in particular relates to a stirring and screening device and a powder making machine. Background technique [0002] Powder preparation is a commonly used production process in industrial production, which usually includes steps such as stirring and sieving. For example, in the field of powder metallurgy, the production process of cemented carbide involves stirring and drying, sieving, mixing and re-drying. The drying step is to dry the alcohol or gasoline in the wet abrasive separately in the drying equipment, then manually shovel the dried powder into the vibrating sieve for sieving, and then manually shovel the sieved powder into the glue blending machine Then add glue or wax solution, start the glue blender to mix, after mixing, manually shovel the mixture into the material tray and then further dry. The above-mentioned powder preparation method has the following deficiencies: 1. During ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a stirring and screening device, which solves the problem that the structure of the stirring and screening equipment existing in the prior art is not compatible due to the limitation of its own functions, and it cannot be prepared to integrate the two functions into one. Equipment, and the technical problems of low quality powder and large loss, it can complete the stirring and screening steps in the powder preparation process in the same equipment, and has the advantages of simple structure and easy operation

[0005] Another object of the present invention is to provide a milling machine, which solves the problem of complex and cumbersome milling equipment structure in the prior art, resulting in low quality of milling materials, low milling efficiency, and milling cycle. long technical question
