Description

Technical Field

[0001] This invention relates to the field of paper-faced gypsum board production technology, and in particular to a central feeding mixer. Background Technology

[0002] A mixer is a device used in the production of paper-faced gypsum board to mix and stir gypsum powder, water, additives, etc., into a gypsum slurry. The mixer rotor is a component of the mixer, which has the function of stirring and mixing the powder, water, and additives within the mixer evenly.

[0003] During the mixing process, gypsum lumps are prone to form in the internal cavity, rotor surface, inner side of the upper cover liner, and root of the lower mixing roller facing away from the direction of rotation. These gypsum lumps will fall off during the operation of the mixer, and the falling gypsum lumps can cause paper breakage, affecting the continuous production of paper-faced gypsum board. It is necessary to avoid the formation of lumps as much as possible.

[0004] The upper stirring shaft, mounted on the top cover, serves to clean the upper surface of the rotor and any gypsum blocks adhering to the lower stirring shaft, as well as participate in the mixing of the slurry. Any detached gypsum blocks are broken up by the shearing action of the upper stirring roller and the lower stirring roller on the rotating rotor surface, preventing large pieces of gypsum from entering downstream equipment. Summary of the Invention

[0005] In some embodiments of this application, a central feeding mixer is provided. The gypsum powder inlet of this application is located at the center of the central feeding mixer, so that the gypsum powder is added through the water inlet component at the bottom of the mixer. At the center of the mixer, water and powder are separated by a partition plate. The water forms a water film on the surface of the rotor under the action of the rotating water spraying blades, which is fully and evenly mixed with the gypsum powder that is also rotated and pushed on the upper layer. This improves the mixing efficiency and reduces clumping caused by uneven feeding of gypsum powder. It solves the problem that existing mixers are prone to gypsum clumping during the mixing process, such as the internal cavity, rotor surface, inner side of the upper cover liner, and the root of the lower stirring roller facing away from the direction of rotation. The gypsum clumping will fall off during the operation of the mixer, which can cause paper breakage and affect the continuous production of paper-faced gypsum board.
