Direct dismounting type buffer slide chute

Abstract

The invention relates to a direct dismounting type buffer slide chute, which comprises a chute body, wherein a material passage which is in vertically arranged is arranged in the chute body, a plurality of material baffle plates are arranged in the material passage from top to bottom, each material baffle plate partially seals the cross section of the material passage, the adjacent material baffle plates are alternately distributed in the vertical direction, so materials fall on the next material baffle plate after being blocked by the former material baffle plate in the passage. The transferred materials directly and mutually impact materials deposited above the material baffle plates, the buffer effect is good, and the abrasion of the materials on the slide chute is avoided, so the service life of the slide chute is prolonged. In addition, the buffer slide chute has the advantages of simple structure, convenient manufacture and low cost.

Description

technical field [0001] The invention relates to a discharge chute at the place where materials are reloaded in a bulk material conveying system, in particular to a direct discharge buffer chute which avoids the impact of materials on equipment. Background technique [0002] In chemical, metallurgy, grain, building materials, ports, electric power, coal, mining and other bulk material conveying systems, material reloading is essential, that is, materials are reloaded from one conveying equipment or storage equipment to the next conveying equipment or storage equipment . In the case of ordinary reloading, just install a discharge chute directly under the discharge funnel. However, if the height difference between the two reloading equipment is too large, the impact of the material falling freely on the downstream equipment will cause certain damage. At this time, it is necessary to require the chute to reduce the increased speed of the material due to free fall, thereby redu...

AI Technical Summary

Problems solved by technology

At present, the material channel in the usual chute is designed to be multi-turn or spiral to achieve the purpose of buffering. Although the chute with this structure can partially delay the material's sliding speed, its sliding speed is still relatively fast, which is harmful to downstream equipment. The impact of the impact will still cause some damage. In addition, because the material is in direct contact with the chute wall, the scouring wear of the turning point of the chute or the wall of the spiral channel is relatively large.

In order to solve this problem, CN2892744Y discloses a chute with a buffer plate in the tank body. A layer of material is retained on the buffer plate as a protective layer to resist the erosion and wear of the tank body by the unloaded material. The disadvantage is that the tank body There is a certain inclination angle. The protective layer formed by this material accumulation can only cover the lower part of the material channel of the tank body, but cannot cover the entire inner wall of the tank body. The falling speed of the material cannot be reduced, so the impact of the material on the downstream reloading equipment cannot be slowed down, so the chute is not suitable for direct unloading and large height difference occasions

CN200985201Y discloses a chute for reloading operations with large height differences. The channel of the chute is a turning channel composed of a horizontal turning section and an inclined section, wherein the material stays in the horizontal turning section to form an inclined surface as a protective layer, which can play a buffer and reduce the impact force, the disadvantage is that the inclined section will inevitably be washed and worn, so the service life of the chute is short, and the structure is complicated, the production is difficult and the cost is high
