Description

Technical Field

[0001] This application belongs to the field of daily chemical product manufacturing equipment, and more specifically, it relates to a liquid material mixing device for the production of daily chemical products. Background Technology

[0002] Chemical products such as shampoos and shower gels that people frequently use in their daily lives are collectively referred to as daily chemical products or daily necessities. For example, in the production of emulsified cosmetics, the oil phase and the water phase need to be mixed and emulsified. For example, Chinese patent publication CN119034533A discloses a liquid material mixing device for the production of daily chemical products, specifically disclosing the following technical content: It includes a mixing tank, inside which a stirring shaft is rotatably inserted, and the top end of the stirring shaft is connected to the output shaft of a servo motor fixed to the top of the mixing tank via a coupling; multiple discs are installed along the length of the stirring shaft, and each disc has multiple arc-shaped swing grooves arranged in a circumferential array on its outer ring surface, with symmetrically staggered shearing blades installed in each arc-shaped swing groove; each arc-shaped swing groove is equipped with a swing support assembly, which is used to adjust the angle of the symmetrically staggered shearing blades; the above technical solution enables the symmetrical shearing blades, driven at high speed by the discs, to generate high-speed rotating shearing and stirring forces within the mixing tank, breaking oil droplets in the oil phase into fine droplets and dispersing them into the aqueous phase, thereby allowing the oil and aqueous phases to be quickly mixed and emulsified within the mixing tank.

[0003] According to the description, multiple impellers need to be installed on the stirring shaft, each impeller having multiple shear blades arranged in a circumferential array, offset symmetrically at different angles.

[0017] Both the outer shaft sleeve 5 and the inner shaft 6 extend into the interior of the tank 22, with the inner shaft 6 protruding from the bottom opening of the outer shaft sleeve 5. A U-shaped outer rod 7 is connected to the outer shaft sleeve 5. The U-shaped outer rod 7 is an inverted U-shaped rod, with its top end fixedly connected to the outer shaft sleeve 5. The bottom end of the inner shaft 6 is coaxially connected to the inner shaft stirring rod 8 via an inner shaft connector 9. The inner shaft stirring rod 8 has several inner shaft blade groups 10 arranged along its length. The U-shaped outer rod 7 has outer shaft stirring blades 11 positioned corresponding to the inner shaft blade groups 10. The outer shaft stirring blades 11 are distributed along the length of the U-shaped outer rod 7, and their sides face the location of the inner shaft stirring rod 8. The U-shaped outer rod 7 has an outer scraper 13 on its side facing the inner wall of the tank 22. The outer scraper 13 is in contact with the inner wall of the tank 22. The outer scraper 13 and the outer shaft stirring blade 11 are offset in the length direction of the U-shaped outer rod 7.

[0018] The bottom surface of the tank 22 is also provided with a high shear mixer 16, which is connected to the output end of a shear mixer motor 17, and the shear mixer motor 17 is connected to the bottom end of the tank 22.

[0019] Example 2: See also Figure 1 and Figure 2 A liquid material mixing device for daily chemical product manufacturing is disclosed. The inner shaft blade assembly 10 includes a blade sleeve fixedly connected to the inner shaft 6, and stirring blades connected to the blade sleeve. The angle between the stirring blades and the horizontal plane is an acute angle. The outer scraper 13 and the U-shaped outer rod 7 are detachably connected, i.e., a scraper connector 14 composed of bolts is provided at the connection position between the outer scraper 13 and the U-shaped outer rod 7. The inner shaft stirring rod 8 and the inner shaft 6 rotate in opposite directions to the outer shaft sleeve 5. The outer scraper 13 is a corrosion-resistant and wear-resistant plastic sheet.

[0020] The bottom end of the U-shaped outer rod 7 is rotatably connected to the bottom end of the inner shaft stirring rod 8 through the inner and outer connecting rods 15.

[0021] The structure and connection relationships of the remaining parts are the same as those described in the foregoing embodiments.

[0022] Based on the above embodiments, the following paragraphs will continue to describe in detail the technical features involved and the functions and roles of these technical features in this technical solution, so as to help those skilled in the art to fully understand the technical solution and reproduce it.

[0023] In this application, the inner shaft drive motor 1 and the inner shaft gearbox 3 can drive the inner shaft 6, so that the inner shaft 6 rotates together with the inner shaft stirring rod 8 connected by the inner shaft connector 9, thereby driving the rotation of several sets of inner shaft blade groups 10 on the inner shaft stirring rod 8, and the stirring of the liquid inside the tank 22 is achieved through the inner shaft blade groups 10.

[0024] In this application, the outer shaft drive motor 2 and the outer shaft gearbox 4 can drive the outer shaft sleeve 5, so that the outer shaft sleeve 5 and the U-shaped outer rod 7 connected to it can rotate in the opposite direction to the inner shaft stirring rod 8 and the inner shaft 6. Since the output power of the inner shaft drive motor 1 and the outer shaft drive motor 2 are not the same, there is also a difference in their rotational speed. The rotational speed of the inner shaft blade assembly 10 is greater than the rotational speed of the U-shaped outer rod 7.

[0025] In this application, the U-shaped outer rod 7 is an inverted U-shaped structure rod, located on both sides of the inner shaft stirring rod 8. Along its length, parallel to the inner shaft stirring rod 8, several outer shaft stirring blades 11 are distributed, with the outer shaft stirring blades 11 located on the side of the U-shaped outer rod 7 facing the inner shaft stirring rod 8. Several outer scrapers 13 are also provided on the side of the U-shaped outer rod 7 facing the inner wall of the tank 22. The outer scrapers 13 and the outer shaft stirring blades 11 are offset on the U-shaped outer rod 7, and the outer scrapers 13 can be detachably connected to the U-shaped outer rod 7 via scraper connectors 14. Preferably, the outer scrapers 13 are plastic scrapers.

[0026] In this application, the angle between the stirring blades in the inner shaft blade assembly 10 and the horizontal plane is an acute angle, preferably 45°. The aforementioned inclined blades can stir the liquid in the middle of the tank 22 as they rotate with the inner shaft stirring rod 8.

[0027] In this application, a high-shear mixer 16 is also provided at the bottom of the tank 22. The high-shear mixer 16 can realize the shearing and upward conveying of the liquid, realize the overall flow of the liquid in the tank 22, and promote the mixing of different liquid raw materials in the tank 22.

[0028] In this application, the heating and cooling jacket 21, jacket inlet pipe 18, and jacket outlet pipe 12 can achieve cooling or heat preservation inside the tank 22, and the heating or cooling pipeline can be connected according to the actual processing requirements.

[0029] In this application, the top of the tank 22 is provided with several feed pipes 20. The feed pipes 20 can realize the addition of different liquid raw materials into the tank 22, and can also cooperate with the tank outlet 19 at the bottom and the pumping device to realize the circulation of liquid between the bottom and the top.

[0030] Finally, although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
