Description

Technical Field

[0001] This utility model relates to the field of emulsification pump technology, specifically to a multi-port feeding device and its emulsification pump. Background Technology

[0002] An emulsifying pump is a device that uses the high-speed relative motion between a rotor and a stator to shear, emulsify, and mix materials. It is widely used in the food, chemical, and pharmaceutical industries. During the use of an emulsifying pump, the feeding device is a key component ensuring the material processing effect; its feeding efficiency and the material premixing effect directly affect the final emulsification quality. One powder emulsification pretreatment device, publication number CN211411653U, involves water entering the tank through a tangential interface. After forming a vortex, the powder is evenly dropped from the top inlet onto the surface of the water in the tank. The rotating water carries away the powder, ensuring thorough and uniform mixing before it enters the pre-cutting pump for emulsification. This method requires injecting sufficient water into the tank before premixing, making it impossible to inject materials simultaneously for processing. This results in low processing efficiency, poor vortex mixing ability, and a tendency for powder to agglomerate.

[0003] Existing emulsifying pumps typically employ single-port or simple multi-port feeding devices. These devices lack an effective pre-mixing stage before materials enter the pump body, often resulting in direct mixing and emulsification of various materials. This leads to poor mixing uniformity and requires longer emulsification times to achieve the desired effect. Some feeding devices with pre-mixing functions usually require an additional drive mechanism to operate the stirring components, increasing energy consumption and manufacturing costs, raising the failure rate, and hindering stable operation and maintenance.

[0004] Existing emulsification pumps lack an effective premixing stage before materials enter the pump body. Multiple materials often enter the pump body directly for mixing and emulsification, resulting in low mixing uniformity and efficiency. Some feeding devices with premixing functions usually require an additional drive mechanism to operate the stirring components, which increases the energy consumption and manufacturing cost of the equipment, and also increases the failure rate of the equipment. Utility Model Content

[0005] The purpose of this invention is to provide a multi-port feeding device and its emulsifying pump to solve the problems of poor mixing effect and the need for additional power to drive stirring in the prior art mentioned in the background section.

[0016] The technical effects and advantages of this utility model are as follows: 1. The multi-port feeding device and its emulsifying pump are equipped with a spiral mixing impeller in the premixing structure. After various materials enter the premixing structure from the annularly distributed connecting pipe, the mixing impeller rotates automatically under the dual action of gravity and material impact, which fully stirs and premixes the materials. This avoids the problem of uneven mixing after the materials directly enter the pump body, lays a good foundation for the subsequent emulsification process, and significantly improves the final emulsification quality. 2. This multi-port feeding device and its emulsifying pump and mixing impeller do not require additional drive mechanisms such as motors. They can achieve rotation and mixing by relying solely on the gravity and impact of the material itself, which effectively reduces the energy consumption of the equipment. At the same time, it reduces the number of drive components, lowers the manufacturing cost and failure rate of the equipment, and facilitates later maintenance. 3. The multi-port feeding device and its emulsifying pump have multiple sets of connecting pipes evenly arranged in a horizontal ring at the top of the premixing structure. The ring-shaped distribution structure makes the material more uniform when entering the premixing structure, further improving the mixing effect. The ball valve on the feeding pipe can flexibly control the feeding amount and feeding speed of each material to meet different process requirements. Attached Figure Description
