Rotation type segregation-preventing device

Abstract

The invention discloses a rotation type segregation-preventing device. The rotation type segregation-preventing device comprises a stock bin; a belt machine and a rotation driving mechanism for controlling the belt machine to rotate around the axis of the stock bin are arranged below a feeding port of the stock bin; a feed divider capable of sliding back and forth relative to the belt machine is arranged on the belt machine; furthermore, the belt machine, the rotation driving mechanism and the feed divider are connected with a PLC control system for controlling mutual collaboration of the beltmachine, the rotation driving mechanism and the feed divider; the PLC control system controls the rotation driving mechanism to enable the belt machine to rotate around the axis of the stock bin; meanwhile, the feed divider does reciprocating motion along the belt machine, so that materials can fall into the stock bin at constant speed and uniformly in a spiral motion track; the materials can beeffectively guaranteed to prevent segregation after entering the stock bin and, the materials in the stock bin are consistent with the feeding grading and the stable quality of the materials is guaranteed; and the rotation type segregation-preventing device is simple in structure, low in cost, high in reliability, flexible in control and high in practicability, is low in investment cost, low in energy consumption and low in operating cost, and has good economic practicability.

Description

technical field [0001] The invention relates to a rotary anti-segregation device, which belongs to the technical field of anti-segregation processing equipment for finished sand and gravel aggregates. Background technique [0002] The stable gradation of machine-made sand and gravel aggregate is an important prerequisite to ensure the stable quality of concrete. [0003] At present, silos are often used to store materials in the market, which has the advantages of small footprint and large storage capacity. The materials can be directly sent to the mixing station to produce concrete through the conveying device, eliminating the need for loading by the loader. However, there are also disadvantages in storing materials in silos. The existing silos are generally very high, and the materials in the silos will cause segregation of sand and gravel aggregates during the storage process, which cannot guarantee the stable quality of concrete. [0004] During the falling process of t...

AI Technical Summary

Problems solved by technology

[0007] (1) During the production and transportation process, large particles of sand and gravel aggregates are deposited, resulting in severe segregation;

[0008] (2) The silo capacity of sand and gravel aggregate is large, and the material dropping point is single, and it is easy to segregate when dropped from a high place. After high-quality aggregate enters the silo, it becomes low-quality aggregate due to segregation

[0009] Existing mixing plants generally do not have anti-segregation treatment devices. After the segregated sand and gravel aggregate enters the mixing plant, even though the concrete formula of the mixing plant has not changed, the gradation of the segregated aggregate has actually changed, which not only affects the mixing performance of concrete , leading to a decline in production efficiency, and the quality of the prepared concrete cannot be guaranteed, seriously affecting the durability and safety of concrete
