Anti-segregation steady flow bin

Abstract

The invention relates to an anti-segregation steady flow bin. The anti-segregation steady flow bin comprises a bin body and a round-to-square elephant trunk fixed to the opening position in the bottom of the bin body, a vertically-arranged rectangular pyramid feeding hopper is further connected to the top of the bin body in an inserted mode, a first feeding pipe and a second feeding pipe which are obliquely arranged are further connected to the left side and the right side of the rectangular pyramid feeding hopper in an inserted mode correspondingly, and a square-to-round elephant trunk is further fixed to the opening position in the lower end of the rectangular pyramid feeding hopper and arranged inside the top of the bin body. According to the anti-segregation steady flow bin, three strands of materials which are larger in particle size difference and enter the bin body can be fully mixed in the rectangular pyramid feeding hopper in advance, then fall into the bin body by means of the square-to-round elephant trunk and finally are fed into a roller press through the round-to-square elephant trunk, then segregation of materials with the larger particle size difference is effectively avoided, material particles fed into the roller press are evenly distributed, larger deviation of roller gaps of the roller press is thoroughly avoided, and violent vibration is prevented.

Description

technical field [0001] The invention relates to a segregation-preventing steady-flow bin. Background technique [0002] At present, in the grinding system for preparing cement, the final grinding system composed of roller press, V-type classifier and fine classifier has the characteristics of low energy consumption and convenient operation, so it is widely used in the cement industry. [0003] In the final grinding system, there are three main strands of materials entering the roller press for grinding: fresh material, V-selected coarse powder and selected coarse powder; the above three strands of material are fed into the roller press through the steady flow chamber, When the existing steady flow bin is feeding, it is easy to cause segregation of materials with large particle size differences, and then the distribution of the material particles fed into the roller press is uneven, and the gap between the rolls of the roller press is relatively large. Large deviations, thus...

[0003] In the final grinding system, there are three main strands of materials entering the roller press for grinding: fresh material, V-selected coarse powder and selected coarse powder; the above three strands of material are fed into the roller press through the steady flow chamber, When the existing steady flow bin is feeding, it is easy to cause segregation of materials with large particle size differences, and then the distribution of the material particles fed into the roller press is uneven, and the gap between the rolls of the roller press is relatively large. Large deviation, thus causing severe vibration, needs further improvement
