Description

Technical Field

[0001] The utility model belongs to the technical field of homogenization, and particularly relates to a hopper structure for a high-pressure homogenization device. Background Art

[0002] The hopper structure of a high-pressure homogenization device is an important part to ensure the smooth entry of materials into the homogenization chamber. The hopper body is a container for storing materials to be homogenized, usually made of stainless steel or other corrosion-resistant materials to ensure that it is not affected by the chemical properties of the materials during the processing. The design of the hopper body should consider the fluidity of the materials and the overall layout of the device so that the materials can smoothly enter the homogenization chamber. Since in the hopper structure of the related technology, when the materials enter the hopper, air will enter the hopper together with the materials. After the air enters the homogenization chamber, it will affect the homogenization effect of the materials under high pressure, resulting in the problem that the materials cannot be evenly dispersed or emulsified, and further leading to a decline in product quality.

The hopper barrel body and the feed barrel body are integrally connected. The outer wall of the hopper barrel body is of a cylindrical structure, and the outer wall of the feed barrel body is of a conical structure.

[0018] Compared with the prior art, the hopper structure for a high-pressure homogenization device of the present utility model has the following advantages:

[0019] 1. The silo stirring mechanism continuously stirs the materials to prevent the layering of materials in the silo and ensure the uniformity of the material composition during the homogenization process. Multiple stirring paddles are evenly arranged on the driving rotating rod, and through rotational motion, the materials can be quickly and effectively mixed, improving the pretreatment effect before homogenization. By setting a reasonable stirring speed and using appropriate stirring paddles, the entrainment of air during the stirring process can be reduced, the bubble content in the materials can be lowered, and the homogenization effect can be improved.

[0020] 2. The barrel stirring mechanism uses spiral stirring blades, which can evenly transfer the materials from the bottom of the barrel to the homogenization chamber, ensuring that the materials enter the homogenization process evenly. Through continuous spiral motion, the spiral stirring blades can efficiently stir the materials, avoid dead corners, and ensure that the materials are fully mixed before entering the homogenization chamber. This prevents the precipitation of high-viscosity materials or multiphase materials in the barrel and ensures the consistency of the materials during the homogenization process.

[0021] 3. The exhaust mechanism, through a vacuum pump and an exhaust pipeline, effectively removes the air inside the hopper, preventing air from entering the homogenization chamber, thereby ensuring the stability and consistency of the homogenization effect. Through the function of the exhaust mechanism, the bubble content in the materials is reduced, enabling the materials to be more evenly dispersed and emulsified in the homogenization chamber, improving the homogenization efficiency and product quality. The entry of air into the homogenization chamber can cause cavitation, wearing the internal parts of the equipment. The exhaust mechanism can effectively avoid this situation, extend the service life of the equipment, and reduce maintenance costs. Through the continuous operation of the exhaust mechanism, the pressure inside the hopper is kept stable, preventing the unstable operation of the equipment and the fluctuation of the homogenization effect caused by pressure fluctuations.

[0022] 4. The sealing structure can effectively prevent the leakage of materials from the inside of the equipment to the external environment, maintaining the cleanliness and stability inside the equipment. During the high-pressure homogenization process, the sealing structure can withstand high pressure and maintain the pressure stability inside the system. Effective sealing can prevent pressure loss, ensure that the homogenization process is carried out at the set pressure, and thus improve the homogenization effect. BRIEF DESCRIPTION OF THE DRAWINGS
