A kind of lifting device and lifting method for storing cement

Abstract

The invention relates to a lifting device for storing cement and a lifting method, wherein a lifting device for storing cement comprises a box body provided with a feeding port and a discharging port, and a lifting chain rotatably arranged in the box body, and the lifting chain is installed on the lifting chain. There is a lifting hopper. The lifting hopper includes a bucket body and a fixed block fixed with the lifting chain. The fixed block is provided with a vertically extending chute, and a slider fixed to the bucket body is slid in the chute. The lower end of the slide is connected with the bottom plate of the chute through an impact spring, a limit plate above the slider is fixed on the fixed block, and the distance between the slider and the limit plate is less than the length of the impact spring in its natural state. In the present invention, an impact spring and a limit plate are arranged when passing through, and the bucket body is accelerated and blocked when the material is thrown, thereby increasing the speed difference between the bucket body and the cement, and improving the throwing effect; The lever principle realizes the alarm of material shortage in the box, which is convenient for the staff to understand the feeding situation into the box.

Description

technical field [0001] The invention relates to the technical field of cement production equipment, in particular to the field of cement storage, in particular to a lifting device for storing cement and a lifting method. Background technique [0002] In the cement production process, in order to facilitate storage, the processed cement is usually placed in the storage silo. Currently, there are two main ways to deliver cement to the storage silo. One is pneumatic conveying, which is suitable for short-term and fast conveying. The first is to use a bucket elevator to lift the cement to the upper feed port of the cement silo, which is suitable for continuous production and is widely used. [0003] However, when the current bucket elevator is throwing materials, the bucket body and the lifting chain are relatively static, and only relying on the action of centrifugal force and gravity, it is prone to incomplete throwing, and a small amount of cement is often left at the bottom ...

Problems solved by technology

[0003] However, when the current bucket elevator throws materials, the bucket body and the hoisting chain are relatively stationary, relying only on the centrifugal force and gravity, it is easy to cause incomplete throwing of materials, and a small amount of cement often remains at the bottom of the bucket body , after a long time of use, it will affect the capacity of the bucket body
