Multi-station continuous shot blasting equipment for lifting chains

Abstract

The invention discloses multi-station continuous shot blasting equipment for lifting chains. The multi-station continuous shot blasting equipment comprises a chassis, a centrifugal fan, shot blastingdevices, a bucket type lifting device, a shot and dust separator, a shot storage bin, a multidirectional spiral conveyor, a chain feed device and a chain discharge device; a first support roller and afourth support roller which are arranged in a shot blasting area of the chassis have the same height; a second support roller is higher than the first support roller and the fourth support roller; athird support roller is slightly lower than the first support roller and the fourth support roller; a plurality of chain feed transmission sprockets are mounted at the chain feed device side by side;a plurality of chain discharge transmission sprockets are mounted at the chain discharge device side by side; the lifting chains located between the chain feed transmission sprockets and the chain discharge transmission sprockets are mounted in a twisted state; and first lifting chain sections of the lifting chains located between the first support roller and the second support roller are loose; and second lifting chain sections of the lifting chains located between the second support rollers and the third support roller and third lifting chain sections located between the third support rollerand the fourth support roller are tensioned. Both the outer surfaces of the lifting chains and the inner dead angle between chain rings can be treated; and the multi-station continuous shot blastingequipment is compact in longitudinal dimension, and high in shot blasting treatment efficiency.

Description

【Technical field】 [0001] The invention relates to a lifting chain multi-station continuous shot blasting equipment, which belongs to the technical field of lifting chain shot blasting. 【Background technique】 [0002] With the country's emphasis on environmental protection issues and the continuous strengthening of rectification efforts, social responsibility drives enterprises to actively follow up on the implementation of environmental rectification policies. As far as the lifting industry is concerned, the problem of surface cleaning and treatment of lifting chains must be transformed from the production mode of discharge first and post-treatment to a cleaner and more environmentally friendly production mode, that is, from the traditional bucket dumping method to the environmentally friendly one. Changes in approach. [0003] The lifting chain for lifting hoist is a high-precision chain with short links. The diameter of the link is 4-12mm. It is related to the performanc...

AI Technical Summary

Problems solved by technology

[0007] 3. The processing technology of the rolling barrel can easily lead to the problem of knotting of the lifting chain and the time-consuming and labor-intensive treatment of unknotting after knotting;

[0008] 4. Serious problems such as high labor intensity, low work efficiency, high energy consumption, high noise, and air pollution caused by flying dust
