Embodiment Construction

[0062]Referring now to the accompanying drawings, specific embodiments of the present invention will be described in detail. What is described here is only a preferred embodiment of the present invention, and those skilled in the art can think of other ways to realize the present invention on the basis of the preferred embodiments, and the other ways also fall within the scope of the present invention.

[0063] The invention provides a steady flow feeder for conveying powder. For example, the steady flow feeder can be used in the process of feeding and batching coal powder, raw meal powder, mineral powder, fly ash, kiln dust and other powder materials in the cement production process, and solves the problem of material interruption during powder conveying Or the problem of feeding fluctuations such as punching. Introduce in detail below in conjunction with accompanying drawing.

[0064] Such as figure 1 As shown, the steady flow feeder 1 according to the first embodiment of...

Abstract

The invention provides a steady-flow feeder. The steady-flow feeder comprises a stirring bin, a feeding bin, a driving device and a gas flow assisting device. An opening for receiving powder is formed in the top of the stirring bin, and a stirring device capable of rotating around the vertical axis is arranged in the stirring bin. The top of the feeding bin is provided with a feeding port communicated with the bottom of the stirring bin, the bottom of the feeding bin is provided with a discharging port staggered with the feeding port, and a feeding impeller capable of rotating around the vertical axis is arranged in the feeding bin. The driving device is used for driving the stirring device and the feeding impeller to rotate. The gas flow assisting device is provided with a flow assisting gas circuit which is arranged in the top wall of the feeding bin and communicated with gas in the feeding bin, and the flow assisting gas circuit is used for generating flow assisting gas flowing outwards through the discharging port from the position above the discharging port. According to the invention, the stirring device enables the powder to keep flowability and avoid dead angles caused by accumulation, and flow assisting gas generated by the gas flow assisting device can overcome the reverse blowing effect of the conveying gas flow of the downstream conveying device, so that the powder stably and uniformly flows, the feeding fluctuation is reduced, and the conveying quantity is accurately metered.

Description

technical field [0001] The invention relates to a steady flow feeder. Background technique [0002] There are scenes of conveying powder in industrial production. Taking the production process of cement as an example, it includes the process of feeding and batching of coal powder, raw meal powder, mineral powder, fly ash, kiln dust and other powder materials. Most of these processes use impeller feeders, screw conveyors or rotor scales to achieve quantitative delivery of powder materials. Due to the reasons of the feeding equipment itself or the process, the powder conveying process is prone to problems such as feeding fluctuations such as punching and cutting. [0003] For example, due to the limitation of its own structure, the size of the feed port of the impeller feeder is limited, so that the amount of powder it receives is small, and it is prone to material breakage, and the unevenness of receiving powder leads to fluctuations in feeding Big. Moreover, only one bla...
