Embodiment 2

[0048] In order to describe the working modes of each control and monitoring equipment in more detail, a specific embodiment is now used as a representative to deepen the understanding of the content of the present invention, specifically:

[0049] The basic return pipe 6 is provided with a first valve 12 , and the first valve 12 controls the on-off of the basic return pipe 6 .

[0050] The basic return pipe 6 realizes the transportation of materials from the upper hopper lift 4 to the feed port 5 and back to the hopper 7 through the first power device 13 . The first power device 13 may be a dust extraction device for dust materials, or a dust blowing device, and is not limited thereto, and is intended to realize the circulation and transportation of materials in the basic return pipe 6 .

[0051] The additional return pipe 11 is provided with a second valve 14 , and the second valve 14 controls the on-off of the additional return pipe 11 .

[0052] The additional return pipe...

Abstract

The embodiment of the invention discloses a gypsum powder dry material feeding control device which comprises a big stock bin, a feeding funnel lifter, and a conveying device for conveying materials in the big stock bin to a feed inlet the feeding funnel lifter through a variable-frequency power device; the feed inlet of the feeding funnel lifter is connected with a return bin through a basic return pipe; the return bin is connected with a return funnel lifter; an additional return pipe capable of conveying excessive return materials into the feed inlet from the return bin is arranged betweenthe return bin and the feed inlet of the feeding funnel lifter; the additional return pipe can be further matched with the basic return pipe so as to convey the excessive materials into the return binfrom the feed inlet; a windmill material level detection device is arranged on the feed inlet of the feeding funnel lifter and is electrically connected with a controller; and the controller controlsthe basic return pipe and the additional return pipe to convey the materials according to material level information detected by the windmill material level detection device. The method comprises thesteps of feeding, detecting the material level, and adjusting the material level. According to the gypsum powder dry material feeding control device provided by the invention, the feeding efficiencyis improved, and the feeding stability and the continuous production are ensured.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of feeding devices, in particular to a control method and device for feeding gypsum powder dry material. Background technique [0002] Bucket elevator, also called bucket elevator, is called bucket elevator in full. It is a continuous conveying machine that uses a series of hoppers evenly fixed on the endless traction member to lift materials vertically. The bucket elevator has the advantages of large conveying capacity, high lifting height, stable and reliable operation, and long service life. It is suitable for conveying powdery, granular and small non-abrasive and small abrasive materials, such as: feed, Coal, cement, stone, sand, clay, ore, etc., are widely used in the field of material transportation. [0003] During the transportation of plaster powder of Paris, when the return material returned to the return bin through the return pipe through the feed port of the upper hopp...
