Description

Technical Field

[0001] This utility model relates to the field of emulsification pump technology, and in particular to an internal and external circulation emulsification pump. Background Technology

[0002] Emulsification refers to the process of combining two or more immiscible liquids into a stable mixture through mechanical action. Emulsification pumps, through their specialized internal structure and operating principle, can effectively achieve this process.

[0003] First, the core components of an emulsifying pump typically include a rotor and a stator. The rotor rotates at high speed inside the stator, generating strong shear and centrifugal forces. These forces act on the liquid to be mixed, causing it to disperse and mix rapidly in a short time. The gap between the rotor and the stator is very small, usually only a few millimeters, which subjects the liquid to extreme shearing as it passes through, thus achieving the emulsification effect.

[0004] Secondly, the working principle of an emulsifying pump also involves the principles of fluid dynamics. After entering the pump body, the liquid is subjected to the high-speed rotation of the rotor, generating strong turbulence. This turbulence increases the relative velocity between the liquids, further promoting mixing and emulsification.

[0005] Finally, emulsifying pumps have a wide range of applications in practical fields, such as the food industry, cosmetics manufacturing, and pharmaceutical industry. In these industries, emulsifying pumps can effectively mix oils, water, and other additives into stable emulsions, thereby improving product quality and performance. For example, in the food industry, emulsifying pumps can be used to make emulsified sauces, ice cream, and other products, giving them better taste and stability.

[0006] Current emulsification pumps are all single-cycle emulsification pumps. Utility Model Content

[0007] In view of the above-mentioned shortcomings, this utility model provides an internal and external circulation emulsifying pump that can realize external and internal circulation emulsification of emulsified materials, thereby improving the emulsification effect.

[0008] To achieve the above objectives, the embodiments of this utility model adopt the following technical solutions:

[0009] An internal and external circulation emulsifying pump includes a drive motor and an emulsifying head connected to the drive motor. The emulsifying head has a shearing cavity with an opening on the side opposite to the drive motor. The shearing cavity contains a shearing head connected to the drive motor. A return pipe is connected to the lower side of the shearing cavity. An eccentric positioning plate and an eccentric connecting plate are provided at the opening of the shearing cavity. The edge of the eccentric connecting plate can be driven to separate from the cavity wall of the shearing cavity to form a gap or to contact to form a seal. The eccentric positioning plate and the eccentric connecting plate are movably connected to limit the maximum stroke of the eccentric connecting plate.

[0010] According to one aspect of the present invention, the shearing head includes a shearing impeller and an impeller hub, wherein the shearing impeller is connected to the output shaft of the drive motor.

[0011] According to one aspect of the present invention, the shearing chamber includes a main shearing chamber and a bias shearing chamber, the return pipe is connected below the bias shearing chamber, and the shearing head is disposed in the main shearing chamber.

[0012] According to one aspect of the present invention, the eccentric positioning plate is disposed on the upper side of the shearing main cavity, and the eccentric positioning plate is an annular structure with an opening in the middle.

[0013] According to one aspect of the present invention, a sealing ring is provided between the bottom of the impeller hub and the bottom of the shearing chamber.

[0014] According to one aspect of the present invention, a bracket is provided between the drive motor and the shearing cavity.

[0015] According to one aspect of the present invention, the edge of the eccentric connecting plate and the upper edge of the shear cavity wall are arranged in parallel and have an angle relative to the horizontal direction, the angle being 0° to 90°.

[0016] According to one aspect of the present invention, the shear head is fixedly sleeved on the output shaft of the drive motor via a connecting shaft and a key.

[0017] According to one aspect of the present invention, the connecting shaft is sealed to the bottom of the shearing chamber via a mechanical seal dynamic and static ring structure.

[0018] According to one aspect of the present invention, a water-retaining ring is provided at the bottom of the connecting shaft where it connects to the drive motor.

[0019] The advantages of this invention are as follows: The return pipe of the emulsifying pump can be connected to the inlet of the emulsifying tank, allowing the emulsified material to form an external circulation outside the tank. This external circulation mode is generally used for emulsifying high-viscosity, high-oil, and high-protein materials, effectively improving material processing efficiency. It features a large circulation volume, multiple batches, and less foaming, ensuring that all materials in the tank are emulsified. The system can select the emulsification frequency (30-50 times per hour) according to the material characteristics. An internal circulation is formed by the gap between the eccentric connecting plate and the shearing chamber wall, and the intake of the emulsifying pump, connecting to the tank. For ordinary materials, the emulsification mode can be changed to internal circulation mode by adjusting the return control valve of the return pipe. The emulsifying head can shear the material at high speed, resulting in smaller particle sizes and higher emulsification efficiency. Attached Figure Description

[0028] The return pipe of the emulsifying pump can be connected to the inlet of the emulsifying tank, allowing the emulsified material to form an external circulation outside the tank.
