Gypsum board powder grinding and conveying device

Abstract

The invention relates to a gypsum board powder grinding and conveying device. The device includes: a grinder, a conveyor, and a cloth bag screener. The grinder includes: a first bracket, a grinding shell, a screen arranged on the upper part of the grinding shell, Rotary mill, right inclined material outlet pipe, the bottom of the first bracket is provided with a first motor connected with the rotary mill; the conveyor includes: a feeding hopper, a spiral conveying shell, and a spiral conveying rod arranged in the conveying shell. The left end of the screw conveying rod is connected to the second motor arranged outside the conveying shell; the bag filter includes: the first cloth bag connected to the discharge port at the right end of the spiral conveying shell, the second cloth bag sleeved outside the first cloth bag, the sleeve The non-porous cloth bag connected to the outside of the second cloth bag, the second cloth bag has smaller pores than the first cloth bag. The structure design of the present invention is relatively reasonable, it is not easy to cause powder blockage, the powder material can be graded and screened, it is convenient and practical, and it is suitable for further popularization and application.

Description

technical field [0001] The invention relates to the technical field of structural design of a grinding and conveying device, and more specifically, relates to a grinding and conveying device for gypsum board powder. Background technique [0002] With the rapid development of the building materials industry, gypsum board manufacturers have higher and higher requirements for equipment in order to reduce production costs. During the transportation of gypsum board powder, because the powder is easy to absorb the moisture in the air, a small amount of lumpy material will be produced. If the lumpy material cannot be screened out, it will affect the mixing and molding of the gypsum board slurry, making the production uncontinuous. . There are two forms of traditional gypsum powder screening, one is the combination of screw conveyor and vibrating sieve, specifically, the powder is transported to the vibrating sieve by the screw conveyor, and the powder is sieved in the vibrating si...

AI Technical Summary

Problems solved by technology

In the combination of the above-mentioned screw conveyor and vibrating screen, the working process of the vibrating screen is to vibrate the whole screen through the vibrating motor, and the powder will fall off due to the vibration on the screen surface, so it is not easy to be blocked on the screen surface, but the working process Due to the large amount of vibration dust, the working environment is bad

In the conveying form in which the above-mentioned sieve and screw conveyor are integrated, since the screen surface is fixed on the shell of the screw conveyor, the screen surface is stationary. When the powder is sieved, the powder is absorbed by the external air. Moisture is easily bonded to the sieve surface, causing blockage of powder and failure of normal production
