Description

Technical Field

[0001] This utility model relates to the field of grinding equipment technology, and more specifically to a slurry grinding and mixing system. Background Technology

[0002] In industries such as chemical, pharmaceutical, and food processing, the grinding and mixing of slurries is a critical production step. Traditional slurry grinding uses colloid mills, whose surfaces are easily worn, resulting in a significant decrease in refining efficiency. Colloid mills are not universally applicable for handling various particle sizes, requiring extensive operational adjustments to process particles of different sizes. Although colloid mills can fine-tune the applied mechanical shear force, this increases the complexity of operation and leads to higher maintenance costs.

[0003] Inline high-shear emulsifiers utilize a high-speed rotating rotor and stator to generate strong hydraulic shearing, centrifugal extrusion, high-speed cutting, and collision, enabling materials to be fully dispersed, emulsified, homogenized, pulverized, and mixed. However, during the high-shear emulsification process, a large amount of heat is generated inside the emulsifier due to mechanical friction and the interaction between materials. The inability to effectively control the temperature leads to overheating of the emulsifier, affecting product quality and production efficiency.

[0004] Therefore, how to provide a slurry grinding and mixing system that can effectively control the temperature of the emulsifier, prevent overheating, and improve production efficiency and product quality is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the present invention provides a slurry grinding and mixing system, which aims to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A slurry grinding and mixing system includes an inline high-shear emulsifier, a tank connected to the inlet end of the inline high-shear emulsifier, and a cooling circulation system connected to the inline high-shear emulsifier.

[0008] Through the above technical solution, the slurry grinding and mixing system provided by this utility model, by introducing a tank and a cooling circulation system, and in conjunction with the structure of a pipeline high-shear emulsifier, can achieve continuous supply and efficient grinding and mixing of slurry; the tank allows for the pre-storage and preliminary mixing of a large amount of slurry, realizing the processing and stable supply of slurry, while the cooling circulation system effectively controls the temperature of the pipeline high-shear emulsifier, preventing overheating, improving the stability of the system, and improving the efficiency and quality of grinding and mixing.

[0009] Preferably, in the above-mentioned slurry grinding and mixing system, the inline high-shear emulsifier is provided with a demineralized water inlet and a demineralized water outlet. The demineralized water inlet is connected to the cooling circulation system, and the demineralized water outlet is connected to a recovery tank via a first connecting pipe. This ensures that the inline high-shear emulsifier is effectively cooled during operation, reducing energy consumption and improving equipment stability and production efficiency. The recovery tank facilitates recycling and subsequent reuse, improving utilization rate.

[0010] Preferably, in the above-mentioned slurry grinding and mixing system, a circulation pump and a first solenoid valve are installed on the first connecting pipe. This can improve the efficiency and controllability of demineralized water circulation, ensure that the pipeline high-shear emulsifier operates at the optimal temperature, improve the recycling of demineralized water, reduce scale and corrosion, and extend service life; at the same time, the use of the first solenoid valve can achieve precise control of water flow and improve the automation level of the system.

[0011] Preferably, in the above-mentioned slurry grinding and mixing system, the cooling circulation system includes a demineralized water storage tank, the outlet of which is connected to the demineralized water inlet via a second connecting pipe, and a second solenoid valve is installed on the second connecting pipe. This allows for precise control of the demineralized water supply, improving the system's response speed and control accuracy.

[0012] Preferably, in the above-mentioned slurry grinding and mixing system, the top of the tank has an inlet, and the bottom of the tank has an outlet. The outlet is connected to the inlet via a third connecting pipe. The design of the inlet and outlet of the tank, as well as the use of the third connecting pipe, makes the addition and discharge of slurry more convenient and efficient. This design helps to achieve continuous production and processing of slurry and improves production efficiency.

[0013] Preferably, in the above-mentioned slurry grinding and mixing system, a third solenoid valve and a basket filter are installed on the third connecting pipe. The third solenoid valve can further control the flow of the slurry, and the basket filter can prevent foreign objects from entering the inline high-shear emulsifier, protect the inline high-shear emulsifier from damage, extend the service life of the equipment, and ensure the quality of the final product.

[0014] Preferably, in the above-mentioned slurry grinding and mixing system, the outlet end of the inline high-shear emulsifier is connected to a material collection box via a fourth connecting pipe; a fourth solenoid valve is installed on the fourth connecting pipe. This allows for the effective collection and storage of materials that have undergone emulsification, pulverization, and mixing. Simultaneously, the use of the fourth solenoid valve enables precise control of material flow, improving the system's automation level and production efficiency.

[0015] As can be seen from the above technical solution, compared with the prior art, the present invention discloses a slurry grinding and mixing system, which has the following beneficial effects:

[0016] This invention enables a highly efficient production process through continuous slurry supply and efficient grinding and mixing. The combination of a cooling circulation system and a pipeline high-shear emulsifier effectively controls the temperature during emulsification, preventing overheating and ensuring product quality. The use of a basket filter ensures that the slurry entering the pipeline high-shear emulsifier is free of impurities, improving the quality of the final product. Precise control of the solenoid valve enhances the system's stability and response speed. Attached Figure Description
