Novel full-automatic powder producing system

Abstract

The invention discloses a novel full-automatic powder preparation system, which comprises a main material bin, a material feeding machine, an impulse type flow meter, a main material conveyor, an auxiliary material adding machine, an auxiliary material bin, a burden machine and a mixer and so on, a screening device is arranged between the material feeding machine and the main material conveyor, a decrement method weighing device is arranged between the auxiliary material bin and the auxiliary material adding machine, and a negative pressure source is also arranged to facilitate the whole system to operate in a negative pressure state. A central controller, a remote computer and a PLC device are arranged at a controlling part. The invention realizes the advance control of the auxiliary material flow, further ensures the accuracy, stability and consistency of the compounding ratio of the product ingredients, can meet the requirement of various products to the grain size to lead the production line to have the functions of one-button ordinal start, one-button ordinal stop and interlock of each production link. The powder leakage and diffusion in the process of material transporting, mixing and packaging and so on are prevented, the pollution to the surrounding environment is avoided, and the environmental protection is facilitated.

Description

technical field [0001] The invention belongs to a material mixing preparation device, and in particular relates to a novel automatic powder preparation system with the environmental protection function of a screening device, a weight reduction method weighing device and a negative pressure source. Background technique [0002] In the powder production process in the pharmaceutical, pigment, food, building materials and other industries, it is very important to ensure the uniform ratio of main materials and auxiliary materials. The Chinese patent "Automatic Powder Preparation Device" (ZL Patent No. 02209500.4) discloses a fully automatic powder preparation device, which includes a main material conveyor connected to the main material bin and an auxiliary material adding machine connected to the auxiliary material bin. The auxiliary material adding machine is connected to the batching machine, the batching machine is connected to the mixer, the mixer is connected to the finish...

AI Technical Summary

Problems solved by technology

However, there are still certain limitations in the uniformity of material particle size and the accuracy of proportioning, which cannot meet the particle size requirements of various products for different purposes.

Moreover, powder leakage and diffusion will inevitably occur during material transportation, mixing, packaging, etc., which will pollute the surrounding environment and be unfavorable for environmental protection.
