Novel high-speed belt bucket elevator

Abstract

The invention relates to a novel high-speed belt bucket elevator. The novel high-speed belt bucket elevator comprises a main shell, a material conveying mechanism and other parts, wherein the material conveying mechanism comprises a supporting frame fixedly connected with the main shell, an upper roller and a lower roller, a belt, hoppers and a driving assembly, wherein the arc face of the upper side of the supporting frame is in an arc shape, the upper roller and the lower roller are rotationally connected with the main shell, the belt is rotationally connected with the supporting frame, the upper roller and the lower roller, the hoppers are arranged on the belt and distributed at intervals, and the driving assembly is arranged on the main shell and used for driving the upper roller to roll and rotate. Under the condition that the structure of the bucket elevator is changed or not changed, in the working process of the novel high-speed belt bucket elevator, materials in the hoppers pass through the supporting frame and the upper roller and are discharged from a discharging port under the combined action of centrifugal force and gravity, materials can be timely and fully thrown out of the hoppers and fall into a material guide groove, the number of the materials falling into the material guide groove is increased, and therefore almost no material flows back.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to a novel high-speed elevator with buckets. Background technique [0002] Bucket elevator is a conveying machine that continuously lifts granular materials in the vertical or near-vertical direction. It is mainly used to convey powdery and small bulk materials, such as coal, ore, grain, etc., with high efficiency, low energy consumption, It has the advantages of wide application, dust-free and environmental protection. [0003] With the current continuous growth of port bulk cargo business, how to improve the transportation efficiency of bulk cargo has become an urgent problem to be solved, which puts forward higher requirements for the production efficiency and operation capacity of the bucket elevator. In order to improve the working efficiency of the bucket elevator, it is generally considered from two aspects, that is, to increase the running speed of the hopper or to increa...

Problems solved by technology

[0005] (1) Without changing the structure of the bucket elevator, the running speed of the lifting hopper will have a certain impact on the feeding and unloading process of the bucket elevator. During the feeding process, increasing the running speed of the hopper will Insufficient filling of the hopper results in insufficient feeding efficiency; also in the unloading process, because the unloading method of the material depends on the speed and radius of the driving drum, increasing the running speed of the hopper increases the centrifugal force on the material, which is originally the gravity The unloading method may be changed to centrifugal unloading, and the hoist that originally adopted the centrifugal unloading method will aggravate the phenomenon of premature centrifugal unloading at the unloading end due to the increase in speed, reducing the amount of materials falling into the chute. lead to a large amount of material backflow

[0006] (2) Under the condition of changing the structure of the bucket elevator, if the loading capacity of the hopper is only increased, during the unloading process, due to the deep structure of the hopper, the material cannot be thrown out of the hopper in time and falls into the guide chute , resulting in a large amount of material backflow
