Rotary vertical elevator and elevating method

Abstract

The invention discloses a rotary vertical elevator. The rotary vertical elevator comprises a rack and a roller, wherein the roller is located in the rack, a cavity for carrying materials is formed inthe roller, the opening direction of the cavity points to the rotary axis of the roller, a material blocking device is arranged in the roller above one side of a rotary lifting material, a follow-up mechanism is arranged on the material blocking device, and when the materials move to the material blocking device along with the roller, the follow-up mechanism and the roller rotate synchronously, sothat the materials in the cavity and the material blocking device form a relative synchronous conveying state. The rotatable roller is arranged, the cavity for carrying the materials is formed in theroller, the material blocking device is arranged in the roller above one side of the rotary lifting material, the follow-up mechanism is arranged on the material blocking device, and when the materials ascend along with the roller and move to the material blocking device, the follow-up mechanism and the roller synchronously rotate to enable the materials in the cavity and the material blocking device to form the relative synchronous conveying state, vertical lifting of the materials is achieved, all components of the material blocking device basically have no sliding friction with the materials in the working process, the service life is long, energy consumption is low, the downtime is short, and the maintenance cost is low.

Description

technical field [0001] The invention belongs to the field of conveying machinery, in particular to a rotary vertical hoist for vertical conveying of loose materials. Background technique [0002] Conveying machinery can be divided into conveyors with flexible components according to their structural characteristics (the traction component is a reciprocating closed system, such as belt conveyors, chain conveyors, bucket elevators, etc.) and conveyors without flexible components. Machine (using the rotating motion or vibration of the working components to convey the material in a certain direction, and the components do not have the form of reciprocating cycle, such as screw conveyors, vibrating conveyors, etc.). [0003] In the traditional sand and gravel aggregate production line, different crushing equipment needs to transfer and transfer materials. Currently, belt conveyors are usually used to complete the above work. The belt conveyor has the characteristics of strong co...

AI Technical Summary

Problems solved by technology

The belt conveyor has the characteristics of strong conveying capacity and long conveying distance, but because the belt conveyor can only be installed at an angle of 15°-20°, the crushing equipment is generally arranged on the same plane, with a height difference of 4- 8 meters, so in order to transfer the material to the feed port of the crushing equipment at the corresponding height, the only way to increase the distance between the equipment

The length and consumption of the corresponding belt conveyor will increase significantly, and it will also occupy more land resources, resulting in an increase in cost and energy consumption. Sometimes the cost of the belt conveyor will even account for more than 50% of the cost of the entire production line.

Under the increasingly stringent environmental protection pressure, the investment and operating energy consumption of the dust removal system also lead to a substantial increase in the cost of aggregate preparation, reducing the competitiveness of the product

[0004] Although there is a bucket elevator that can realize the vertical lifting of materials, this equipment uses an independent hopper and a chain drive, which has a relatively complicated structure, low conveying efficiency, small feed particle size, and limited minimum conveying height, which cannot meet the requirements of the sand conveyor. The use requirements of stone aggregate production line

[0005] There are also some belt conveyors with partitions on the rubber belt, which appropriately increases the conveying angle, but also reduces the conveying capacity and greatly reduces the service life, which still cannot meet the requirements of the sand and gravel aggregate production line.
