Proportioning device

Abstract

The invention discloses a proportioning device, comprising a proportioning box with enclosed periphery, wherein five material bins with cutting tools are arranged on the top of the proportioning box; the bottoms of the material bins extend into the proportioning box; an opening is arranged on the top of each material bin; a pneumatic gate valve is arranged at the bottom of each material bin; a track is arranged at the bottom of the proportioning box; an electric proportioning trolley is arranged on the track; the electric proportioning trolley can travel on the track; an electronic weigher is arranged on the electric proportioning trolley; a proportioning hopper is arranged on the electronic weigher; the proportioning hopper is arranged below the five material bins; an openable flexible electric door curtain is arranged at one side of the proportioning box; and the proportioning trolley can drive outwards from the flexible electric door curtain through a guide track. The proportioning device has the advantages of reducing the use time of travelling cranes, largely improving production efficiency, effectively preventing fugitive dusts from harming human health, and improving working security.

Description

technical field [0001] The invention relates to a batching device for batching in the production process of magnesia-carbon bricks. Background technique [0002] In the production process of magnesia-carbon bricks, five kinds of raw materials are usually used, namely: coarse particles, fine particles, fine powder, recycled materials, and graphite. These five raw materials need to be batched according to different proportions. Uniform, and finally pressed into shape. The current batching process is as follows: the ton bags containing five kinds of raw materials - coarse particles, fine particles, fine powder, recycled materials, and graphite are hoisted one by one by the crane, and then the workers use knives to cut the ton bags one by one. , Put the raw materials into the batching hopper one by one, and at the same time, the quality of each raw material is measured by a special person. In the above-mentioned batching process, the ton bags of raw materials are cut manually....

AI Technical Summary

Problems solved by technology

In the above-mentioned batching process, the ton bags of raw materials are cut manually. If the suspension of the ton bags is not firm or the driving accident is easy to cause safety accidents, there are potential safety hazards; In the open environment, the dust formed by raw materials seriously endangers the health of workers; during the batching process, the driving frequency is very high, which makes the motor spline shaft of the lifting mechanism prone to fatigue and fracture, and every time raw materials are added, the driving needs to be operated separately. Seriously affect the speed of ingredients, low work efficiency
