Lifting device for storing cement and lifting method

Abstract

The invention relates to a lifting device for storing cement and a lifting method. The lifting device for storing cement comprises a box body provided with a feeding port and a discharging port and a lifting chain rotationally arranged in the box body, and a lifting hopper is installed on the lifting chain and comprises a hopper body and a fixing block fixedly connected with the lifting chain; and a sliding groove extending in the vertical direction is formed in the fixing block, a sliding block fixedly connected with the hopper body is arranged in the sliding groove in a sliding mode, the lower end of the sliding block is connected with a bottom plate of the sliding groove through an impact spring, a limiting plate located above the sliding block is fixedly arranged on the fixing block, and the distance between the sliding block and the limiting plate is smaller than the length of the impact spring in the natural state. According to the lifting device for storing cement, by arranging the impact spring and the limiting plate, the hopper body is accelerated and blocked during material throwing, the speed difference between the hopper body and cement is increased, and the material throwing effect is improved; and by arranging a bearing plate and a proximity sensor, a material shortage alarm in the box body is realized by utilizing the lever principle so that a worker can conveniently know the material feeding condition in the box body.

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
