A gypsum board slurry production line with the function of adjusting the initial setting time

Abstract

The invention discloses a gypsum board slurry production line with the function of adjusting the initial setting time, which includes a belt conveyor, a raw material mixing device, a retarder output device, and a retarder flow regulating system connected with the retarder output device. When the initial setting slurry width is unqualified through the retarder flow adjustment system, the retarder output flow rate of the retarder output device is adjusted accordingly, and the retarder concentration of the slurry in the raw material mixing device is changed, thereby changing The initial setting time of the slurry is used to obtain the slurry with excellent performance. The degree of automation is high, which avoids the hidden dangers of product production quality due to the inability to monitor and adjust the initial setting time of the slurry manually. Moreover, the belt conveyor is equipped with a temperature The adjustment device is used to adjust the hydration reaction temperature of the unqualified initial setting slurry through the temperature adjustment device, so that it can be well connected with the subsequent slurry and reduce the defective rate of gypsum board.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of gypsum board production, in particular to a gypsum board slurry production line with the function of adjusting the initial setting time. Background technique [0002] Gypsum board is a material made of building gypsum as the main raw material. It is a building material with light weight, high strength, thin thickness, convenient processing, sound insulation, heat insulation and fire resistance. One of the new lightweight panels. [0003] When producing gypsum board, it is necessary to calcinate the gypsum in the stockyard into gypsum blocks. The gypsum blocks are supported by abrasives to support gypsum powder. After cooling, the gypsum powder is mixed with various ingredients and water in a certain proportion to form a slurry. The slurry is transported on a belt conveyor. After preliminary solidification, cover the upper surface paper on the discharge slurry, and make gypsum bo...
