[0032] The following further details the present application with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the relevant utility model and do not limit the utility model. Additionally, it should be noted that for the sake of description, only the parts related to the utility model are shown in the drawings.

[0033] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The following will detail the present application with reference to the drawings and in combination with the embodiments.

[0034] At least refer to Figures 1 - 5 As shown, the embodiment of the present utility model provides a dispersion emulsification device, including: reaction kettle 10, high-speed emulsification mechanism 30 and ultrasonic mechanism 20.

[0035] The reaction kettle 10 can be made of, but is not limited to, Q316 material, which is an austenitic stainless steel with good corrosion resistance, heat resistance, and mechanical properties. The other accessories of the reaction kettle 10 are made of Q304 material. The volume of the reaction kettle 10 is about 55L, and the maximum actual usable volume can be 50L. The wall thickness of the reaction kettle 10 is 4mm. The inner surface of the kettle wall is finely polished, and the welding seams are precisely polished to ensure the smooth flow of materials and reduce residues.

[0036] In addition, as Figure 1 shown, a kettle bottom leakage valve 70 is also provided at the bottom 102 of the reaction kettle 10, which is convenient for disassembly and cleaning, ensuring the cleanliness and operational convenience of the equipment.

[0037] The high-speed emulsification mechanism 30 includes a rotor and a stator. The rotor and the stator mesh with each other, and each stage of the stator and rotor has several layers of gear rings. The high-speed rotation of the rotor generates a strong centrifugal force, forming a strong negative pressure area. The material is sucked into the working chamber and is subjected to comprehensive actions such as shearing, centrifugal extrusion, impact tearing, and turbulence in the gap between the stator and the rotor, generating the tension to split the liquid droplets. After the liquid leaves the small holes of the stator, the pressure rises again, thereby generating the cavitation effect. The homogenizing head rotates at a high speed to shear, disperse, and impact the material. In this way, the material will become finer and the homogenization is completed.

[0038] Among them, at least part of the high-speed emulsification mechanism 30 passes through the reaction kettle 10 and extends into its interior.

[0039] As Figure 1 and Figure 3 shown, the length of the high-speed emulsification mechanism 30 extends in the vertical direction. The lower end of the high-speed emulsification mechanism 30 passes through the kettle mouth 101 of the reaction kettle 10 and is arranged close to the bottom 102 of the reaction kettle 10. The high-speed emulsification mechanism 30 performs coarse dispersion of the material, and the material in the reaction kettle 10 is quickly broken and refined under the action of strong shear force. After the preliminary dispersion effect meets the requirements, its rotation speed can be appropriately reduced and then the stirring function can be performed instead.

[0040] The ultrasonic mechanism 20 includes an ultrasonic rod 21. The material of the ultrasonic rod 21 is a material with high strength and high elastic modulus, such as aluminum alloy or super-hard aluminum alloy, to ensure the structural stability and durability under high-frequency vibration.

[0041] Among them, at least part of the ultrasonic rod 21 passes through the reaction kettle 10 and extends into its interior, and the length direction of the ultrasonic rod 21 is inclined relative to the vertical direction.

[0042] As Figure 1As shown, the length direction of the ultrasonic rod 21 is inclined relative to the vertical direction. The angle α between the length direction of the ultrasonic rod 21 and the vertical direction can be 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, ……. The lower end of the ultrasonic rod 21 passes through the wall of the reaction kettle 10 and is arranged close to the bottom 102 of the reaction kettle 10. The lower end of the ultrasonic rod 21 and the lower end of the high-speed emulsifying mechanism 30 can be at the same height.

[0043] It should be noted that a seal is provided between the ultrasonic rod 21 and the area of the wall of the reaction kettle 10 where the ultrasonic rod 21 is located to ensure the airtight performance of the reaction kettle 10; the lower end of the ultrasonic rod 21 is fixed by a stainless steel clamp so that the ultrasonic rod 21 is stationary relative to the reaction kettle 10.

[0044] Since the ultrasonic rod 21 is inclined, the coverage range of the transverse waves and longitudinal waves generated by the ultrasonic rod 21 is expanded, which helps to uniformly disperse and emulsify the large-volume materials; the vibration forces generated by the transverse waves and longitudinal waves can vibrate the refined particles or cause the refined particles to collide with each other, further thoroughly dispersing and emulsifying the particles to obtain sufficiently small microparticles; in addition, the vertical component force of the longitudinal wave makes the microparticles not settle at the bottom 102 of the reaction kettle 10; at the same time, the force of this component on the bottom 102 of the reaction kettle 10 is reduced, avoiding excessive energy concentration at the bottom 102 of the reaction kettle 10 and helping to extend the service life of the reaction kettle 10.

[0045] As an implementable way, as Figure 1 shown, the angle between the length direction of the ultrasonic rod 21 and the vertical direction is α, and 40° ≤ α ≤ 50°.

[0046] Through the setting of α, the coverage range of the transverse waves and longitudinal waves generated by the ultrasonic rod 21 can be maximally expanded, and the effect of vibrating and refining the particles can be optimized as much as possible or the collision probability between the refined particles can be increased. At the same time, the damage to the bottom 102 of the reaction kettle 10 caused by the vertical component force of the longitudinal wave is also maximally inhibited.

[0047] As an implementable way, the ultrasonic rod 21 is an ultrasonic stepped rod, and one end of the ultrasonic rod 21 facing the bottom 102 of the reaction kettle 10 is arranged close to the bottom 102 of the reaction kettle 10.

[0048] As Figure 1 and Figure 4 shown, the ultrasonic rod 21 is an ultrasonic stepped rod, and the diameter of the ultrasonic rod 21 has multiple small-diameter segments and multiple large-diameter segments, and the small-diameter segments and the large-diameter segments are arranged alternately. This increases the complexity of the vibration and helps to optimize the effect of vibrating and refining the particles or increase the collision probability between the refined particles.

[0049] As an implementable way, as Figure 1As shown in the figure, the ultrasonic mechanism 20 is provided with two ultrasonic rods 21, and the two ultrasonic rods 21 are symmetrically arranged with respect to the high-speed emulsification mechanism 30. This increases the complexity of the vibration, which helps to optimize the effect of vibrating and refining particles or increase the collision probability between the refined particles.

[0050] Of course, it can be understood that the ultrasonic mechanism 20 is provided with multiple ultrasonic rods 21, and the multiple ultrasonic rods 21 are arranged around the high-speed emulsification mechanism 30.

[0051] As an implementable mode, the ultrasonic mechanism 20 further includes an ultrasonic vibrating plate 22, and the ultrasonic vibrating plate 22 is arranged on the inner surface or the outer surface of the wall of the reaction kettle 10.

[0052] As Figure 1 shown in the figure, the ultrasonic rod 21 and the ultrasonic vibrating plate 22 are electrically connected to the ultrasonic electric box 93. Multiple ultrasonic vibrating plates 22 are arranged on the inner surface of the wall of the reaction kettle 10, and the multiple ultrasonic vibrating plates 22 are arranged in a ring shape. Among them, the ultrasonic vibrating plate 22 is located between the mouth 101 of the reaction kettle 10 and the upper end of the ultrasonic rod 21. In this way, the ultrasonic vibrating plate 22 can vibrate the refined particles above the ultrasonic rod 21 or make the refined particles collide with each other, further thoroughly dispersing and emulsifying the particles to obtain sufficiently small microparticles; at the same time, the occurrence of vibration dead angles is avoided, which helps to vibrate most of the refined particles in the reaction kettle 10.

[0053] Furthermore, as Figure 1 shown in the figure, at least two rings of ultrasonic vibrating plates are arranged between the mouth 101 of the reaction kettle 10 and the upper end of the ultrasonic rod 21. Among the upper and lower adjacent rings of ultrasonic vibrating plates, the ultrasonic vibrating plates 22 in the upper ring of ultrasonic vibrating plates and the ultrasonic vibrating plates 22 in the upper ring of ultrasonic vibrating plates are arranged staggeredly or aligned.

[0054] In practical applications, during the working process of the ultrasonic rod 21, the ultrasonic vibrating plate 22 and the high-speed emulsification mechanism 30, a large amount of heat is generated, which causes the temperature of the reaction kettle 10 to rise, and it is easy to affect the working stability of the reaction kettle 10.

[0055] Based on this, in order to ensure that the reaction kettle 10 can always work normally and ensure its working stability, the dispersion and emulsification device further includes a cooling mechanism 40. The cooling mechanism 40 is arranged outside the reaction kettle 10, and heat transfer occurs between the cooling mechanism 40 and the reaction kettle 10 to absorb the above heat, so that the reaction kettle 10 is within the normal working temperature range.

[0056] As Figure 1As shown in the figure, the cooling mechanism 40 includes a cooling water pipe 41 and a water circulation system. The cooling water pipe 41 is spirally wound around the outer surface of the kettle wall of the reaction kettle 10, and the water inlet 411 of the cooling water pipe 41 is located below the position where the ultrasonic rod 21 passes through the kettle wall of the reaction kettle 10, and the water outlet 412 of the cooling water pipe 41 is located at the bottom 102 of the reaction kettle 10. The water circulation system enables the cooling water to circulate in the cooling water pipe 41, and the cooling water carries away the above heat, so that the reaction kettle 10 is within the normal working temperature range; at the same time, the production cost is also reduced.

[0057] As an implementable manner, the dispersion emulsification device further includes a deironing mechanism.

[0058] In practical applications, the dispersion emulsification device can be used for the fine dispersion of battery slurries. Due to the friction between the ultrasonic rod 21 and the material, the magnetic material on the surface of the ultrasonic rod 21 falls off, and the magnetic substance poses a safety hazard to the battery. Therefore, the above magnetic substance is adsorbed by the magnetic adsorbent 50, so as to avoid the contamination of the battery slurry by the magnetic substance.

[0059] As Figure 1 shown, the deironing mechanism includes a plurality of magnetic adsorbents 50, and the magnetic adsorbents 50 can be strip-shaped magnet rods. Each magnet rod can generate a high-intensity magnetic field of up to 13000 gauss. The upper end of the magnet rod is located at the kettle mouth 101 of the reaction kettle 10, and the lower end is close to the bottom 102 of the reaction kettle 10. The plurality of magnet rods are arranged around the high-speed emulsification mechanism 30. In this way, the magnet rods can adsorb most of the magnetic substances in the reaction kettle 10 to the greatest extent, and further avoid the contamination of the battery slurry by the magnetic substances.

[0060] As an implementable manner, the dispersion emulsification device further includes a sound insulation cover 80.

[0061] In practical applications, as Figure 1 and Figure 5 shown, considering that the deironing mechanism, the cooling mechanism 40, the ultrasonic rod 21, the ultrasonic vibration plate 22 and the high-speed emulsification mechanism 30 will generate relatively high noise during the working process, making the working environment noisy. Therefore, by setting the sound insulation cover 80, the reaction kettle 10, the deironing mechanism, the cooling mechanism 40, the ultrasonic rod 21, the ultrasonic vibration plate 22 and the high-speed emulsification mechanism 30 are all located inside the sound insulation cover 80, which helps to reduce noise pollution and improve the comfort of the working environment.

[0062] Among them, as Figure 5 shown, the sound insulation cover 80 is provided with a movable door that can be opened and closed, which is convenient for the staff to enter and exit.

[0063] As an implementable manner, the kettle cover 11 of the reaction kettle 10 is opened or closed in a two-point manner.

[0064] As Figure 1 andFigure 2 As shown, on the kettle cover 11 of the reaction kettle 10, a feed inlet 111, an observation port 123, a thermometer port 114, a spare port 112 and a plurality of mounting ports are provided. The plurality of mounting ports include a first mounting port 115 and a second mounting port 116. The first mounting port 115 is used for mounting the high-speed emulsifying mechanism 30, and the second mounting port 116 corresponds one-to-one with the magnetic attachment 50 and is used for mounting the magnetic attachment 50.

[0065] As Figure 1 As shown, on the left and right sides of the reaction kettle 10, lifting mechanisms 60 are respectively provided. The lifting mechanisms 60 can be hydraulic lifting mechanisms 60 or pneumatic lifting mechanisms 60. The power output ends of the lifting mechanisms 60 make reciprocating motions in the vertical direction, and the power output ends of the lifting mechanisms 60 are respectively connected to the left and right sides of the kettle cover 11, so that the kettle cover 11 can make reciprocating motions in the vertical direction, realizing that the kettle cover 11 is covered on the kettle opening 101 of the reaction kettle 10, or the opening of the kettle cover 11.

[0066] Such a setting helps to ensure the stability of the opening or closing of the kettle cover 11 of the reaction kettle 10. At the same time, it helps to miniaturize the design of the emulsifying device.

[0067] As an implementable manner, as Figure 1 shown, in terms of operation control, a multi-channel screen control system is adopted. The multi-channel screen control system includes a control interface 92 and a display 91. The control interface 92 is designed to be simple and intuitive, facilitating quick start-up and precise operation.

[0068] Among them, the total power of the ultrasonic rod 21 and the ultrasonic vibrating piece 22 is 16KW, and the power of the high-speed emulsifying mechanism 30 is 1.5KW, and the rotation speed can reach 2800 revolutions per minute.

[0069] It should be understood that terms such as "center", "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. indicating orientation or positional relationship are based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, so it cannot be understood as a limitation to the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0070] The above description is only a preferred embodiment of the present application and an explanation of the applied technical principles. Those skilled in the art should understand that the scope of the utility model involved in the present application is not limited to the technical solutions formed by the specific combination of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept of the utility model. For example, the technical solutions formed by mutually replacing the above features with the technical features (but not limited to) disclosed in the present application that have similar functions.
