Description

Technical Field

[0001] This invention belongs to the field of colored plaster slurry production technology, specifically relating to a continuous production system and control method for colored plaster slurry based on multi-stage dynamic mixing. Background Technology

[0002] Colored plaster is a premixed dry powder material made from gypsum (α or β type hemihydrate gypsum) as the base material and by adding inorganic or organic pigments and functional additives (such as water-retaining agents, retarders, reinforcing fibers, etc.). Its core feature is that it has uniform color on its own and can be directly mixed with water for plastering construction of building walls without the need for secondary coatings or finishing layers, thus combining decoration and functionality.

[0003] Existing colored plaster mortar production methods mostly employ single-stage mixing equipment, resulting in uneven color dispersion and color differences. Furthermore, air bubbles are difficult to expel during single-stage mixing, leading to poor homogenization and affecting the production quality of the colored plaster mortar. To address this, we propose a continuous production system and control method for colored plaster mortar based on multi-stage dynamic mixing. Summary of the Invention

[0014] A control method for a continuous production system of colored plaster mortar based on multi-stage dynamic mixing includes the following steps: A. Eddy current premixing treatment: Plastering gypsum raw materials and colored pigments are fed into the premixing tank from the plastering gypsum inlet and the colored pigment inlet, respectively. Then, the plastering gypsum raw materials and colored pigments are tilted and conveyed to the center of the premixing tank through the inclined feeding frame, where they are mixed and conveyed together. Next, the eddy current motor is started, driving the first transmission roller and the eddy current blades to rotate. The eddy current blades with the inclined angle tumble and mix the plastering gypsum raw materials and colored pigments to obtain a premix of colored plastering gypsum dry powder raw materials. The premix of colored plastering gypsum dry powder raw materials is then conveyed to the shearing mixing tank through the solenoid valve and the negative pressure screw conveyor. B. Dynamic shearing and mixing process: Additives are fed into the shearing mixing tank, and then the shearing mixing motor is started, driving the second drive roller, the double-end shearing ring assembly and the vortex dispersion assembly to rotate. At this time, several cross shearing rings and arc shearing blocks shear and mix the premixed raw materials and additives of colored plastering gypsum dry powder. The planetary gear set drives the vortex dispersion disk to rotate, so that the arc shearing grooves and vortex dispersion grooves on the vortex dispersion disk form vortex shearing treatment, and perform vortex dynamic shearing and mixing of the premixed raw materials and additives of colored plastering gypsum dry powder to obtain the semi-finished product of colored plastering gypsum slurry. The semi-finished product of colored plastering gypsum slurry is then transported to the homogenizing tank through a solenoid valve and a negative pressure screw conveyor. C. Homogenization and mixing process: The ultrasonic oscillation component and the homogenizing mixing component are started. At this time, the ultrasonic oscillation component oscillates the semi-finished colored plaster slurry in the homogenizing tank. Then, the homogenizing mixing motor drives the homogenizing mixing frame to rotate through the third transmission roller. The homogenizing mixing frame, in combination with the oscillation of the ultrasonic oscillation component, homogenizes and mixes the semi-finished colored plaster slurry in the homogenizing tank and removes air bubbles from the semi-finished colored plaster slurry, thereby obtaining the finished colored plaster slurry and realizing the continuous production of colored plaster slurry.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. The present invention is equipped with a series of first-stage eddy current premixing device, second-stage dynamic shear mixing device and third-stage ultrasonic homogenizing device. By performing a series of eddy current premixing, dynamic shear mixing and ultrasonic homogenizing mixing treatments on the colored plaster raw materials, the dispersion uniformity of colored plaster slurry in the production process is gradually improved, and the efficient and high-quality continuous production of colored plaster slurry is realized. 2. The present invention is equipped with a first-stage vortex premixing device, which adopts a vortex mixing mechanism with an inclined angle. During use, multiple sets of vortex blades with inclined angles tumble and mix the plastering gypsum raw materials and colored pigments, so as to achieve rapid vortex tumbling and mixing of plastering gypsum raw materials and colored pigments. The stirring of multiple sets of vortex blades eliminates the agglomeration of raw materials, and the premixing uniformity reaches 90%, thereby improving the premixing effect of colored plastering gypsum dry powder raw materials. 3. This invention features a two-stage dynamic shearing and mixing device with a double-ended shearing ring assembly and a vortex dispersion assembly. In use, several cross-shaped shearing rings and arc-shaped shearing blocks shear and mix the premixed raw materials and additives of colored plastering gypsum dry powder. The planetary gear set drives the vortex dispersion disk to rotate, causing the arc-shaped shearing grooves and vortex dispersion grooves on the vortex dispersion disk to form vortex shearing treatment. This achieves vortex dynamic shearing and mixing of the premixed raw materials and additives of colored plastering gypsum dry powder, realizing efficient shearing and mixing of the premixed raw materials and additives. The double-ended shearing ring assembly and vortex dispersion assembly with dual shearing and mixing generate high-frequency vortex and shearing force, which quickly breaks up the agglomerates of the premixed raw materials and additives of colored plastering gypsum dry powder, dispersing the particle size of the sheared and mixed colored plastering gypsum slurry to below 5μm, further improving the shearing and mixing effect during the production of colored plastering gypsum slurry. 4. The present invention is equipped with a three-stage ultrasonic homogenizing device 3 having an ultrasonic oscillation component and a homogenizing mixing component. In use, the ultrasonic oscillation component oscillates the semi-finished colored plaster slurry in the homogenizing tank. Then, the homogenizing mixing motor drives the homogenizing mixing frame to rotate through the third transmission roller. The homogenizing mixing frame, combined with the oscillation of the ultrasonic oscillation component, homogenizes and mixes the semi-finished colored plaster slurry in the homogenizing tank, and removes air bubbles from the semi-finished colored plaster slurry. This can quickly eliminate air bubbles and improve the leveling properties of the colored plaster slurry, thereby improving the homogenization performance of the colored plaster slurry.

The planetary gear set (20242) drives the vortex dispersion disk (20241) to rotate, so that the arc shear tooth groove (20243) and vortex dispersion groove (20244) on the vortex dispersion disk (20241) form vortex shear treatment, and perform vortex dynamic shear mixing on the premixed raw materials of colored plastering gypsum dry powder and additives to obtain the semi-finished product of colored plastering gypsum slurry. The semi-finished product of colored plastering gypsum slurry is then transported to the homogenizing tank (301) through the solenoid valve and the negative pressure screw conveyor (4). C. Homogenization and mixing process: The ultrasonic oscillation component (302) and the homogenizing mixing component (303) are started. At this time, the ultrasonic oscillation component (302) oscillates the semi-finished colored plaster slurry in the homogenizing tank (301). Then, the homogenizing mixing motor (3031) drives the homogenizing mixing frame (3033) to rotate through the third transmission roller (3032). The homogenizing mixing frame (3033) combines the oscillation treatment of the ultrasonic oscillation component (302) to homogenize and mix the semi-finished colored plaster slurry in the homogenizing tank (301) and remove the air bubbles in the semi-finished colored plaster slurry to obtain the finished colored plaster slurry, thus realizing the continuous production of colored plaster slurry.
