Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, and specifically discloses an emulsification device. Background Technology

[0002] When emulsifying water-based emulsion products, qualified organic peroxide products, emulsifiers, antifreeze agents, and water are first added to the emulsification tank in proportion for emulsification. The emulsification process generally involves high-speed stirring and shearing to form uniform and stable oil-in-water or water-in-oil fine droplets. The size and droplet size distribution of the final emulsion droplets affect the stability of the water-based emulsion. Water-based emulsions formed by larger droplets or droplets with uneven particle size are prone to demulsification and stratification during storage. Therefore, in order to ensure the storage stability of the product, it is necessary to ensure the quality of the water-based emulsion and ensure the uniformity and stability of the water-based emulsion droplets.

[0003] To ensure the quality of the water-based emulsion during production, it is necessary to transfer the emulsion from one emulsification vessel to another using a high-speed homogenizing pump while simultaneously stirring and shearing within the emulsification vessel. This ensures uniform mixing of the product and eliminates dead volume from shearing. The number of times the material is transferred during production depends on the properties of the product. Due to the high viscosity of the water-based emulsion, the conveying speed is slow, resulting in low production efficiency. Furthermore, since the material is poured between two emulsification vessels, the conveying pipeline needs to be replaced regularly, making the operation relatively frequent. In addition, emulsion residue remains in the pipeline after pouring. Due to the tendency of organic peroxides to decompose at high temperatures, the residual emulsion needs to be cleaned promptly after each process to ensure production safety, making the operation relatively cumbersome.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] The emulsification device includes an emulsification kettle, with an inlet and an outlet at the top and bottom of the kettle, respectively. The emulsification kettle contains a main stirring mechanism and several auxiliary stirring mechanisms spaced apart outside the main stirring mechanism. The main stirring mechanism includes a first motor, a first stirring rod, and a first stirring paddle. The first motor is fixedly located at the center of the top of the emulsification kettle, the first stirring rod is fixedly connected to the output end of the first motor, and the first stirring paddle is fixedly connected to the bottom end of the first stirring rod, with the bottom end of the first stirring rod extending to the bottom of the inner cavity of the emulsification kettle. The auxiliary stirring mechanisms include several second motors, second stirring rods, and second stirring paddles. The several second motors are fixedly located at the top of the emulsification kettle, the several second stirring rods are respectively fixedly connected to the output ends of the several second motors, and the several second stirring paddles are spaced apart and fixedly located below the second stirring rods.

[0007] Furthermore, several second motors are uniformly and spaced apart on the top of the emulsifying tank along the circumference, and several second stirring rods are uniformly and spaced apart on the outside of the first stirring rod along the circumference.

[0008] Furthermore, the output end of the first motor passes through the top of the emulsifying tank and is fixedly connected to the first stirring rod, and the output ends of several second motors also pass through the top of the emulsifying tank and are respectively fixedly connected to several second stirring rods.

[0009] Furthermore, the first impeller is an anchor-type impeller, and the first impeller has an overall U-shaped structure.

[0010] Furthermore, scrapers are fixedly installed on both sides of the stirring paddle, and the opposite sides of the two scrapers are in contact with the inner wall of the emulsification tank.

[0011] Furthermore, the several stirring paddles 2 located at the bottom of the second stirring rod are all located inside the stirring paddle 1.

[0012] Furthermore, a jacket is fixedly fitted on the outer surface of the emulsifying kettle, with a cooling water inlet at the bottom of one side of the jacket and a cooling water outlet at the top of the other side of the jacket.

[0013] Furthermore, several baffles are evenly and regularly fixedly arranged in the middle of the inner wall of the emulsification tank, with the bottom end of the baffles located above the top of the stirring paddle.

[0014] Furthermore, a discharge pipe is fixedly connected to the discharge port, and a discharge valve is installed on the discharge pipe.

[0015] Furthermore, a thermometer and a pressure gauge are fixedly installed at intervals on one side of the top of the emulsification vessel.

[0016] The beneficial effects of this utility model are:

[0017] This invention, through the setting of a main stirring mechanism, can uniformly mix the materials in the emulsification tank, ensuring that the liquid at the tank wall and bottom is always in motion; through the coordinated action of several auxiliary stirring mechanisms, the shearing force can be enhanced and the dead volume of shearing can be avoided during the emulsification process, thus efficiently completing the emulsification of the product and finally obtaining a stable water emulsion product. The shearing action of the auxiliary stirring mechanisms can make the droplets of the water emulsion quickly shrink and become uniform, and the auxiliary stirring mechanisms can also make the droplets in contact with them quickly emulsify; through the synergistic action of the main stirring mechanism and several auxiliary stirring mechanisms, the internal circulation of the emulsion in the emulsification tank can be intensified, further improving the uniformity of the product and the emulsification efficiency of the emulsion.

[0021] Example 1

[0022] like Figure 1 As shown, the emulsification device includes an emulsification tank 1. The top and bottom of the emulsification tank 1 are respectively provided with a feed inlet 8 and a discharge outlet 9. The emulsification tank 1 is provided with a main stirring mechanism and a number of auxiliary stirring mechanisms spaced apart outside the main stirring mechanism. The main stirring mechanism includes a first motor 2, a first stirring rod 3, and a stirring paddle 4. The first motor 2 is fixedly located at the middle of the top of the emulsification tank 1. The first stirring rod 3 is fixedly connected to the output end of the first motor 2. The stirring paddle 4 is fixedly connected to the bottom end of the first stirring rod 3, and the bottom end of the first stirring rod 3 extends to the bottom of the inner cavity of the emulsification tank 1. The auxiliary stirring mechanism includes a number of second motors 5, second stirring rods 6, and stirring paddles 7. The number of second motors 5 are fixedly located at the top of the emulsification tank 1. The number of second stirring rods 6 are respectively fixedly connected to the output ends of the number of second motors 5. The number of stirring paddles 7 are spaced apart and fixedly located at the lower part of the second stirring rods 6.

[0023] Several second motors 5 are uniformly and spaced along the circumference and fixedly installed at the top of the emulsifying tank 1, and several second stirring rods 6 are uniformly and spaced along the circumference and installed on the outside of the first stirring rod 3.

[0024] The output end of the first motor 2 passes through the top of the emulsifying tank 1 and is fixedly connected to the first stirring rod 3. The output ends of several second motors 5 all pass through the top of the emulsifying tank 1 and are fixedly connected to several second stirring rods 6 respectively.

[0025] The number of auxiliary stirring mechanisms is 2-4, and the 2-4 auxiliary stirring mechanisms are evenly and spaced apart from the main stirring mechanism; the body of the emulsification tank 1 is made of stainless steel, preferably 316L; both stirring paddle 1 4 and stirring paddle 2 7 are made of stainless steel, preferably 316L; the main stirring mechanism and several auxiliary stirring mechanisms can adjust the speed and can be selected according to the product type; stirring paddle 1 4 adopts a single-layer anchor stirring, and the vertical height of stirring paddle 1 4 is 1 / 6-1 / 2 of the height of the emulsification tank 1; stirring paddle 2 7 adopts a multi-layer horizontal stirring paddle, and the width of stirring paddle 2 7 is 1 / 8-1 / 4 of the width of stirring paddle 1 4, and the number of stirring paddle 2 7 is 6-15.

[0026] With the above setup, the main stirring mechanism can uniformly mix the materials in the emulsification tank 1, ensuring that the liquid at the tank wall and bottom is always in motion. The coordinated action of several auxiliary stirring mechanisms can enhance the shearing force and avoid dead volume during shearing, efficiently completing the emulsification of the product and ultimately obtaining a stable water emulsion product. The shearing action of the auxiliary stirring mechanisms can rapidly reduce and homogenize the droplets of the water emulsion, and the auxiliary stirring mechanisms can also rapidly emulsify the droplets in contact with them. The synergistic action of the main stirring mechanism and the auxiliary stirring mechanisms can intensify the internal circulation of the emulsion in the emulsification tank 1, further improving the uniformity of the product and the emulsification efficiency.

[0028] Scrapers 10 are fixedly installed on both sides of the stirring paddle 4, and the opposite sides of the two scrapers 10 are in contact with the inner wall of the emulsifying tank 1. By setting the scrapers 10 and having them in contact with the inner wall of the emulsifying tank 1, the material adhering to the inner wall of the emulsifying tank 1 can be scraped off, ensuring the emulsification effect of the emulsifying tank.

[0029] Several agitators 7 located at the bottom of the second agitator 6 are all located inside agitator 4.
