Accurate proportioning and rolling preparation device for diatomaceous earth porous insulating brick

Abstract

The invention relates to the field of diatomaceous earth, in particular to an accurate proportioning and rolling preparation device for a diatomaceous earth porous insulating brick. The accurate proportioning and rolling preparation device for the diatomaceous earth porous insulating brick aims to solve the technical problems. According to the technical scheme, the accurate proportioning and rolling preparation device for the diatomaceous earth porous insulating brick comprises a bottom plate assembly, a filtering unit, a rolling unit and the like, and the bottom plate assembly is connected with the filtering unit. According to the accurate proportioning and rolling preparation device, diatomaceous earth and fly ash are premixed, next, wood chips are screened, coarse wood chips are screened out, then screened fine wood chips are fully and uniformly mixed with the diatomaceous earth and the fly ash to form pug, then the pug is pressed into a flat shape, then the flat pug is rolled, and finally, the rolled pug is extruded to prepare the diatomaceous earth brick pug, so that the product quality is improved.

Description

Technical field [0001] The present invention relates to a field of diatomaceous earth, in particular, to a precision ratio of diatomaceous earth porous insulation bricks and rolling deposited. Background [0002] The diatomite brick refers to a heat insulating article made of porous diatomaceous earth. The main raw material is naturally produced in polyhydrate, and a small amount of binding clay and flammable, the volume density of diatomite brick is 0.7g. / cm3, normal temperature compressive strength is 1 ~ 2MPa, its main component of diatomaceous earth is a silica rock, mainly distributed in China, the United States, Japan, Denmark, France, Romania and other countries, is a biological caused silica Sedimentary rock, it is mainly composed of the remains of ancient diatom, mainly used in industrial kiln and other thermal equipment, heat pipeline insulation, generally withstand the temperature of about 1000 degrees Celsius. [0003] At present, during use in industrial kiln, due ...

AI Technical Summary

Problems solved by technology

[0003] At present, when used in industrial kilns, due to its special properties, diatomite bricks are often used as heat insulation materials to make diatomite porous insulation bricks. In the prior art, in the production process of diatomite bricks In the process, it is necessary to add a certain amount of fly ash and wood chips according to the proportion and fully mix them evenly. Because the wood chips need to be mixed with finer wood chips in actual use, and then the larger wood chips need to be screened out, and because the wood chips The weight is light, and it is difficult to fully mix with diatomaceous earth and fly ash in ordinary mixing methods, which will affect the quality of later products
