High-precision continuous feeding system

Abstract

The invention relates to the technical field of bulk material storage and transportation operation, in particular to a high-precision continuous feeding system. The high-precision feeding system consists of a system A and an automatic control device connected with the system A, wherein the system A consists of a feeding device, a surge bin, a feeding gate, a measuring hopper, a discharging gate, a feeder and a continuous quantitative material output device which is arranged on the lower part of the feeder. The high-precision continuous feeding system is characterized in that: the system A is at least provided a system B in the same structure as the system A in parallel; the system A and the system B are connected with the automatic control device; the measuring hopper consists of a horn-shaped outer cylinder and a reversed horn-shaped inner cylinder which is arranged on the upper middle part of the horn-shaped outer cylinder; one side of the upper part of the measuring hopper is provided with an air communication pipe; the air communication pipe is connected with the lower part of the surge bin; and the surge bin is provided with a material level detector. The high-precision continuous feeding system has a simple structure, can be safely and reliably used and can meet the requirements on continuous and high-precision feeding.

Description

technical field [0001] The invention relates to the technical field of bulk material storage and transportation, in particular to a high-precision continuous feeding system. Background technique [0002] At present, when quantitatively outputting materials, processes such as a feeder with a screw scale or a feeder with a belt scale, and a quantitative hopper in a buffer bin are usually used. [0003] 1) Feeder with screw scale process: This process system consists of a feeding system, storage hopper, frequency conversion speed regulation feeder, screw scale, continuous quantitative output material device, etc. When continuously quantitatively outputting materials, from the feeding system The continuous quantitative output material device is fully sealed, and the combination of dust removal with the dust collector can ensure that the continuous quantitative delivery of materials meets environmental protection requirements. However, because the spiral leaves of the spiral sca...

AI Technical Summary

Problems solved by technology

However, since the device from the feeding system to the continuous quantitative output material device cannot be completely sealed, even if it is combined with the dust removal device, it cannot ensure that the continuous quantitative delivery of materials meets the environmental protection requirements.

In addition, when the feeder supplies the belt scale material, sometimes the material runs out, and the feeding funnel may fall and hurt people when it is used for a long time

And at present, there is no centralized operating system to coordinate a group of buffer bin quantitative hopper feeding system to coordinate the work in order to continuously quantitatively output the material process. It can only feed intermittently, which cannot meet the high-precision proportioning requirements of continuous feeding.
