Automatic integrated weighing device for finished magnesia and material control method thereof

Abstract

The automatic integrated weighing device for the finished magnesia comprises a shell, multiple sets of weighing devices are arranged in the shell, each set of weighing device is sequentially provided with a feeding hopper, a weighing and metering assembly and a discharging mechanism from top to bottom, and the weighing and metering assemblies and the discharging assemblies are connected with a master control terminal through electric signals. A material control assembly used for controlling the discharging flow speed is assembled at a discharging port of the feeding hopper and comprises a transmission mechanism and a material stopping hopper, one end of the transmission mechanism is hinged to the shell, the material stopping hopper is assembled at the other end of the transmission mechanism, and the transmission mechanism drives the material stopping hopper to do pendulum motion at the discharging port. According to the automatic integrated weighing device for the finished magnesia, the multiple sets of weighing devices are arranged, alternate weighing can be carried out, the metering efficiency is improved, meanwhile, each set of weighing device can adjust the flow state at the discharging opening through the material control assembly, and the precise material weighing effect is achieved.

Description

Problems solved by technology

[0003] The accuracy of the ratio of raw materials for refractory production determines the refractoriness and acid and alkali resistance of refractory materials. Therefore, the ratio of various refractory materials must be strictly controlled. However, most of the existing quantitative batching devices for refractory production use Manual or semi-automatic quantitative weighing, cumbersome operation, common problems such as low proportioning accuracy and low efficiency, not only affect the progress of the subsequent production process, but also greatly affect the finished product pass rate of refractory materials, which is not conducive to the production of refractory materials. Therefore, in the production process, accurate and stable weighing can be guaranteed, which is of great significance for the smooth completion of the production process and the precise control of product quality.

[0004] The existing weighing equipment used in the magnesium ore industry is inefficient, and the finished magnesia has a high flow rate due to its high density. error
