A vacuum suction mixed homogenizing pump

Abstract

This utility model discloses a homogenizing pump for vacuum suction mixing. A drive motor drives a homogenizing head via a homogenizing shaft. The homogenizing shaft passes through a bearing housing and a cooling housing and extends into the homogenizing pump body. The homogenizing head is rotatably mounted within the homogenizing pump body. The cooling housing has a water-cooled cavity with an inlet and an outlet communicating with it.

Description

Technical Field

[0001] This utility model relates to the field of homogenizing pump technology, and in particular to a homogenizing pump for vacuum suction mixing. Background Technology

[0002] A homogenizing pump is a device that uses high-speed shearing, extrusion, or collision to refine and uniformly mix materials, and is widely used in food, pharmaceutical, and chemical industries. Traditional homogenizing pumps typically use mechanical homogenizing heads to process materials. However, under conditions of high viscosity, high solids content, or requiring low-temperature temperature control, insufficient heat dissipation often leads to overheating of the homogenizing head, causing problems such as thermal denaturation of materials, accelerated equipment wear, or decreased operating efficiency. Furthermore, conventional homogenizing pumps are prone to generating bubbles or uneven mixing during the mixing process due to material agitation, affecting the stability and quality of the final product.

[0003] To address the aforementioned issues, while existing technologies have proposed solutions using cooling systems to assist heat dissipation, these often employ external cooling devices or localized cooling structures, resulting in low cooling efficiency and insufficient temperature control precision. Furthermore, traditional homogenizer pumps rely heavily on pressure delivery for feeding, making it difficult to effectively prevent air from mixing into the material. This leads to residual air bubbles during homogenization, further reducing mixing uniformity. Therefore, achieving efficient heat dissipation and vacuum suction mixing through integrated design has become a key requirement for improving homogenizer pump performance. Clearly, existing technologies require further improvement and enhancement. Utility Model Content

[0020] This utility model provides a homogenizing pump for vacuum suction mixing. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. In the description of this utility model, it should be understood that the terms "up, down, left, right," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and should not be construed as limiting this utility model; in addition, the terms "installation," "connection," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] Please see Figures 1 to 3 This invention provides a vacuum suction mixing homogenizer pump, comprising: a drive motor 1, a homogenizing shaft 2, a bearing housing 3, a cooling seat 4, a homogenizing pump body 5, and a homogenizing head 6. The drive motor 1 drives and connects to the homogenizing head 6 via the homogenizing shaft 2. The homogenizing shaft 2 passes sequentially through the bearing housing 3 and the cooling seat 4 and extends into the homogenizing pump body 5. The homogenizing head 6 is rotatably disposed within the homogenizing pump body 5. The cooling seat 4 has a water-cooled cavity and an inlet 7 and an outlet 8 communicating with the water-cooled cavity. The inlet 7 and outlet 8 are respectively used to connect to an external water chiller. By setting a direct drive structure between the drive motor 1 and the homogenizing head 6, combined with the design of the homogenizing shaft 2 passing through the bearing housing 3 and the cooling seat 4, stability and efficiency of power transmission are achieved. The water-cooled cavity and circulation interface embedded in the cooling seat 4 can effectively reduce the operating temperature of the homogenizing head 6, avoiding overheating and wear under high load operation. At the same time, the vacuum suction mixing method reduces air mixing during material agitation, improving the uniformity and fineness of the mixing.

[0022] The homogenizing head 6 consists of a core working component comprised of a coaxially precision-assembled homogenizing stator 9 and a homogenizing rotor 10. The homogenizing stator 9, as a fixed component, precisely houses the rotatable homogenizing rotor 10. A powder inlet channel is specially designed on the front end face of the homogenizing stator 9 for quantitative input of raw materials; correspondingly, a fluid inlet is provided on the rear end face of the homogenizing rotor 10 for easy injection of the working medium. The circumferential side of the homogenizing pump body 5 is precision-machined to create a material outlet, ensuring smooth discharge of the processed material. The homogenizing rotor 10 adopts a modular design, mainly composed of a central rotor shaft and a quickly disassembled and replaceable outer rotor. The circumferential surface of the outer rotor is machined using a special process, with multiple high-strength rotating teeth 11 evenly distributed. These teeth 11 are precisely arranged at equal angles along the circumferential direction. The machining precision of each tooth 11 is extremely high, forming a precise clearance fit with the inner wall of the homogenizing stator 9, ensuring both smooth operation and achieving the ideal homogenization effect.

[0023] The circumferential sidewalls of the homogeneous stator 9 are manufactured using advanced processing techniques, with multiple strip-shaped through holes 12 arranged in a ring array. These strip-shaped through holes 12 extend precisely along the axial direction of the homogeneous stator 9, and their size and distribution are optimized by hydrodynamics. The edges of each strip-shaped through hole 12 are chamfered, which ensures structural strength and optimizes the material flow path, enabling the material to achieve the best shearing and homogenization effect when passing through.

[0024] The material outlet adopts a special upward-sloping design, with an adjustable angle of 30° to 90° between its outlet axis and the horizontal reference plane. This inclined arrangement facilitates smooth material discharge. A dedicated fluid interface 13 is provided on the side wall or top of the homogenizing pump body 5. This interface maintains communication with the main fluid inlet through a carefully designed fluid material conveying chamber inside the pump body, ensuring stable fluid medium delivery. The cooling water circulation system of the cooling base 4 adopts a symmetrical layout design, with the inlet 7 and outlet 8 strictly symmetrically distributed along the central axis of the cooling base 4. The axes of the two interfaces form an angle of 150° to 180°, and this large-angle arrangement helps improve the circulation efficiency of the cooling water.

[0025] In addition, the device includes a robust base 14 structure made of high-strength metal, providing a stable support platform for the entire device. The drive motor 1 is securely mounted on the upper surface of the base 14 by bolts, with shock-absorbing pads placed between them to ensure smooth operation. Adjustable height support feet are also designed at the four corners of the base 14 to maintain a level position in different working environments. This structural design not only ensures the stable operation of the drive motor 1 but also effectively reduces vibration and noise generated during equipment operation.

[0026] In summary, the vacuum suction mixing homogenizer of this invention, through the design of an integrated water-cooled cavity within the cooling base 4 and symmetrical connection to an external water chiller, effectively blocks the heat conduction path of the homogenizing shaft 2, significantly reducing the risk of bearing temperature rise and thermal deformation of the sealing structure, and ensuring the long-term sealing stability of the equipment under vacuum suction conditions. Simultaneously, the structure of the drive motor 1 directly connected to the homogenizing head 6 via the homogenizing shaft 2, combined with the separate layout of the powder inlet and fluid inlet, achieves continuous anti-clogging suction of powder under vacuum negative pressure and instant shear mixing with the liquid flow. Combined with the intermittent shearing structure of the homogenizing rotor 10 and stator, it enhances the ultra-fine dispersion capability of materials, ultimately achieving a synergistic improvement in mixing efficiency, product uniformity, and equipment durability. Therefore, this invention effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0027] It is understood that those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of this utility model, and all such substitutions or changes should fall within the protection scope of this utility model.
