Closed efficient double-bin sifter

Abstract

The invention provides a closed efficient double-bin sifter which comprises a rack and a sifter box. The sifter box is fixedly connected into the rack through a hanging device. A left sifter bin, a right sifter bin and a drive chamber are arranged in the sifter box. Heat dissipating windows are arranged on the front side and the rear side of the drive chamber. A fixing plate is arranged horizontally in the middle of the drive chamber. The upper portion of the fixing plate is fixedly connected with a drive motor. A transmission shaft is rotationally connected between the fixing plate and the bottom of the drive chamber. An eccentric block is mounted in the middle of the transmission shaft. The left side of the left sifter bin and the right side of the right sifter bin are fixedly connected with sifter doors through bolts correspondingly. Feeding inlets are formed in the tops of the left sifter bin and the right sifter bin correspondingly. Discharging outlets are formed in the bottoms of the left sifter bin and the right sifter bin correspondingly. Vertical pressing mechanisms are arranged at the tops of the left sifter bin and the right sifter bin correspondingly. Horizontal pressing mechanisms are arranged on the left side of the left sifter bin and the right side of the right sifter bin correspondingly. The closed efficient double-bin sifter provided by the invention is compact in structure, stable in work, convenient and fast to operate, high in screening efficiency and good in screening effect.

Description

technical field [0001] The invention belongs to the technical field of material screening and separation mechanical equipment, and in particular relates to a closed high-efficiency double-chamber sieve. Background technique [0002] Double chamber sieve is mainly used in flour, feed, pharmaceutical, chemical, starch and other industries to achieve the purpose of grading materials or removing impurities. Double-compartment sieve is a commonly used equipment in the grain screening process. It has the advantages of high screening efficiency and good separation effect. On the outside, dust and other pollutants from the outside are easy to cover the surface of the screen and enter the inside of the screen, polluting the materials in the screen, and the screen of the open double-chamber sieve lacks direct positioning. In the middle, the sieve grid is prone to movement, which is easy to cause damage to the sieve grid, thereby affecting the service life of the sieve grid, affecting...

Problems solved by technology

Double-compartment sieve is a commonly used equipment in the grain screening process. It has the advantages of high screening efficiency and good separation effect. On the outside, dust and other pollutants from the outside are easy to cover the surface of the screen and enter the inside of the screen, polluting the materials in the screen, and the screen of the open double-chamber sieve lacks direct positioning. In the middle, the sieve grid is prone to movement, which is easy to cause damage to the sieve grid, thereby affecting the service life of the sieve grid, affecting the service life of the double-chamber sieve and the screening and grading efficiency. At the same time, the materials in the sieve grid are also It is easy to blow out to the outside and pollute the environment; moreover, the sieve grid of the open double-chamber sieve should be equipped with an inner channel for the material, resulting in a reduction in the area of ​​the sieve grid that actually participates in the screening, and virtually reduces the screening efficiency; the sieve body of the double-chamber sieve is suspended The device is hung on the frame. However, when the screen body of the double bin screen currently on the market is hung, the upper end of the hanging device is connected with the frame, and the lower end of the hanging device is set at the bottom of the screen body. The center of gravity of the double-compartment sieve is high, and the rotary motion of the double-compartment sieve is unstable, and the vibration is severe when the height of the screen is large, which seriously affects the use of the double-compartment sieve.

At present, the double-chamber screens commonly used in the market have problems such as material leakage and low screening efficiency, which seriously restrict the quality of finished or semi-finished products.
