Powder batching device and powder batching control system thereof

Abstract

The invention discloses a powder batching device which comprises a plurality of stock bins, weighing hoppers corresponding to the stock bins and a conveying device. A feeding device is arranged at thebottom of each stock bin, the feeding devices are used for feeding raw materials in the stock bins into the corresponding weighing hoppers, an inclined blanking hopper is arranged at the bottom of each weighing hopper, the upper side wall of each blanking hopper extends towards the conveying device to form a baffle, an inserting hole is formed in the joint of each baffle and the upper side wall of the corresponding blanking hopper, electronic scales for weighing the weighing hoppers are arranged at the tops of the weighing hoppers, a driving air cylinder is further installed on the side wallof each weighing hopper, an inserting plate is installed on a telescopic shaft of each driving air cylinder, the driving air cylinders drive the inserting plates to move downwards, and the inserting plates penetrate through the inserting holes and seal discharging holes of the blanking hoppers. The invention further discloses a powder batching control system. The powder batching device and the powder batching control system have the beneficial effects that automatic powder batching is realized; splashing powder is blocked through sealing between the inserting plates and the discharge holes ofthe blanking hoppers and the baffles; the waste of the powder is reduced, so that powder waste is reduced; and the leakage of powder can be avoided, and the proportioning precision of components is ensured.

Description

technical field

[0001] The invention relates to the field of powder proportioning, in particular to a powder proportioning device and a powder proportioning control system thereof. Background technique

[0002] In metallurgy, cement and other fields, it is necessary to crush raw materials, then form powders, and then mix various powders to form new raw material formulas. These formulas have a high ratio of various raw materials. Therefore, it is necessary to strictly control the weight of each raw material.

[0003] The traditional method of proportioning is to manually weigh each raw material separately, and then mix them together according to the proportion, but this method is slow in production efficiency and labor-intensive. With the continuous progress and development of electronic scales, Electronic scales have been able to accurately monitor the weight of materials. Therefore, in powder batching, an automatic batching system has appeared. As a result, the proportion...
