Description

Technical Field

[0001] This utility model relates to the technical field of gypsum production equipment, and in particular to the technical field of foaming devices. Background Technology

[0002] For extra-thick gypsum board, the foaming process can effectively reduce its weight, making it easier to handle and install. It also reduces the overall load on the building, which is more beneficial to the building structure. For example, Knauf standard paper-faced gypsum board uses double foaming technology, which reduces the material density by about 30% compared with ordinary gypsum board.

[0003] The main component of commonly used gypsum board foaming agents is sodium dodecyl sulfate (K12). When the foaming agent is mixed with gypsum slurry, it produces rich and fine foam that is evenly mixed with the gypsum slurry. During the hydration process of gypsum, the foaming agent and gypsum generate intermolecular forces—hydrogen chains—which create steric hindrance, causing defects in the gypsum crystal structure, stimulating gypsum activity, and accelerating the formation of a network-like gypsum skeleton. This results in uniformly distributed bubbles inside the gypsum board, thereby enhancing the strength of the gypsum board, reducing its density, saving raw materials, and improving its physical properties.

[0004] The patent document with publication number CN222021910U discloses a gypsum foaming machine for gypsum production. The foaming machine avoids gypsum from adhering to the inner wall of the upper shell by setting a stirring plate to fit the inner wall, thus reducing the subsequent cleaning work. However, there are still cleaning dead corners when cleaning the inner wall later. Summary of the Invention

[0005] The purpose of this invention is to solve the problems in the prior art by proposing an ultra-thick gypsum board foaming device that can solve the above problems.

[0006] To achieve the above objectives, this utility model proposes an ultra-thick gypsum board foaming device, comprising an outer cylinder, an inner cylinder inside the outer cylinder, an installation ring at the top of the inner cylinder, a placement groove matching the installation ring at the top of the outer cylinder, an installation block on the outer side of the installation ring, an installation slot matching the installation block in the placement groove, a discharge pipe at the bottom of the outer cylinder, a connecting pipe at the bottom of the inner cylinder, the connecting pipe being connected to the discharge pipe, a cover at the top of the outer cylinder, a stirring shaft rotatably mounted on the cover, a plurality of stirring blades on the stirring shaft, a spiral blade at the bottom of the stirring shaft, and the spiral blade being disposed in the connecting pipe.

[0007] Preferably, the bottom of the inner cylinder transitions to the connecting pipe via a conical portion.

[0008] Preferably, the top of the discharge pipe is provided with a connecting groove, and the connecting pipe is fitted into the connecting groove.

[0009] Preferably, a sealing ring is installed at the bottom of the connecting pipe.

[0010] The beneficial effects of this utility model are as follows: By designing the inner cylinder as a detachable structure, the inner cylinder is heated by the outer cylinder during operation, and the inner cylinder can be removed for cleaning, making it convenient to thoroughly clean the inner cylinder and avoid stubborn dirt residue; during stirring, the spiral blades continuously lift the slurry in the connecting pipe upwards to ensure that the material is stirred evenly; during discharge, the spiral blades transport the stirred material to the discharge pipe to prevent the material from clogging due to excessive viscosity.

[0011] The features and advantages of this utility model will be described in detail through embodiments and accompanying drawings. Attached Figure Description
