Description
An adhesion-type production apparatus and method for preparing environmentally friendly asphalt release agents Technical Field
[0001] This invention belongs to the field of asphalt release agent preparation technology, specifically relating to an adhesive production device and method for preparing environmentally friendly asphalt release agents. Background Technology
[0002] Environmentally friendly asphalt release agents are mainly used during asphalt construction and maintenance to form a release film between asphalt and construction equipment, molds, or transport containers. This reduces asphalt adhesion, improves release performance, and simplifies cleaning. With increasingly stringent environmental requirements, environmentally friendly asphalt release agents prepared from animal and vegetable oils, mineral oils, and emulsifiers are gradually replacing traditional solvent-based products. Their preparation process typically involves multiple steps, including heating, stirring, and emulsification with water.
[0003] In existing technologies, environmentally friendly asphalt release agents are mostly prepared using a closed emulsification tank combined with a stirring mechanism. This involves mixing the oil phase and emulsifier under specific temperature conditions, followed by the addition of an aqueous phase to achieve emulsification. However, existing production equipment still has the following shortcomings in actual use: Firstly, existing stirring structures are mostly set at a fixed height, making it difficult to adjust the stirring depth according to changes in material level and viscosity during emulsification. When the material viscosity is high or the level change is large, insufficient stirring and uneven emulsification in certain areas can easily occur, thus affecting the stability and adhesion performance of the final release agent. Secondly, in the water-addition emulsification stage, existing equipment typically adds water to the emulsification tank at a single point or through simple pipelines. The dispersion effect of the aqueous phase in the oil phase is limited, easily causing localized instantaneous dilution or insufficient emulsification, thereby reducing emulsification efficiency and prolonging the preparation cycle.
[0004] In addition, the existing emulsification equipment has a relatively simple sealing structure when the stirring mechanism passes through the top of the cylinder. During the process of adjusting the stirring depth or cleaning and maintenance, the top seal is easily damaged, which not only increases the inconvenience of operation, but may also cause external impurities to enter the emulsification cylinder and affect product quality.

[0013] A method for preparing an environmentally friendly asphalt release agent mainly includes the following steps: S1, mixing: animal and vegetable oils, mineral oil, and emulsifier are added to a high-speed homogenizing emulsifier in a specific ratio for mixing. The high-speed homogenizing emulsifier is set to a specific temperature, the heating device is turned on, and high-speed homogenization is performed for a certain time; S2, emulsification: after the materials in S1 are mixed evenly, pure water at a specific temperature is added dropwise to the high-speed homogenizing emulsifier in a specific ratio, and the mixture is continuously added, stirred, and emulsified.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention provides a sealing height adjustment mechanism that can be raised and lowered synchronously with the fixed rod at the top of the emulsification cylinder, so that the sealing cover plate always maintains a reliable sealing state with the top of the emulsification cylinder during the raising and lowering of the stirring structure. This solves the problem that the existing emulsification device is prone to damage to the seal when adjusting the stirring height, resulting in the entry of external impurities or the volatilization of materials, thereby improving the airtightness of the environmentally friendly asphalt release agent preparation process and the stability of the finished product quality.
[0017] This invention solves the problem of insufficient emulsification caused by the fixed stirring height and difficulty in adapting to different working conditions in the prior art by setting a horizontal plate driven by a hydraulic cylinder in the lifting and stirring structure and using a fixed rod to drive the stirring frame to lift as a whole. This allows the immersion depth of the stirring frame inside the emulsification cylinder to be adjusted according to the material liquid level and viscosity.
[0018] This invention achieves rapid positioning and stable fixation of the stirring structure at different heights by setting an adjusting ring on the sealing cover plate and utilizing the cooperation between the limiting block and the limiting grooves at different heights on the fixing rod. This avoids the problem of stirring instability caused by height drift or vibration during the stirring process, and improves the reliability and repeatability of the stirring process.
[0019] This invention solves the problem of local concentration and insufficient dispersion of the water phase in the traditional single-point water addition method by setting a multi-point dripping mechanism on the sealed cover plate and using an arc-shaped channel and multiple vertical droppers to form multiple independent dripping points. This significantly improves the contact area and emulsification efficiency between the water phase and the oil phase, and shortens the emulsification time.
[0020] This invention, by setting up a linkage control structure consisting of a control ring, a slide bar, a plug, and a spring, and cooperating with an eccentric extrusion mechanism driven by a control cylinder, enables the synchronous opening and closing of multiple dripping points. This allows for centralized control of the dripping amount and frequency, avoiding the problem of inconsistent liquid output at each dripping point, thereby ensuring the stability of the emulsification process and the consistency of the performance of the release agent.
[0021] This invention solves the problem of unstable emulsification effect caused by temperature fluctuations in the prior art by setting a heating rod on the inner wall of the emulsification cylinder, so that the material inside the emulsification cylinder can always be maintained within a suitable temperature range during the stirring and dripping process. This is beneficial to improving the emulsification uniformity and long-term storage stability of environmentally friendly asphalt release agents. Attached Figure Description

Embodiments
[0025] Referring to Figures 1-8, an attachment-type production device for preparing environmentally friendly asphalt release agents includes an emulsification mechanism 1. The emulsification mechanism 1 includes a base plate 11 fixed to the ground surface. The base plate 11 provides stable support for the entire device to avoid shaking during emulsification and stirring, which would affect the emulsification effect. An emulsification cylinder 12 is fixed on the upper surface of the base plate 11. The emulsification cylinder 12 is used to contain animal and vegetable oils, mineral oils, emulsifiers, and subsequently added water phases, and serves as the main container for the emulsification reaction. A lifting and stirring structure 2 is provided on the rear side of the top of the base plate 11. The lifting and stirring structure 2 is used to solve the problem of fixed stirring height and difficulty in adapting to different liquid levels and material viscosities in the prior art. The lifting and stirring structure 2 includes a hydraulic cylinder 21. The hydraulic cylinder 21 provides stable and controllable vertical lifting power. A horizontal plate 22 is installed on the top of the hydraulic cylinder 21. The horizontal plate 22 serves as the mounting base for the stirring component and the sealing component. The end of the horizontal plate 22 extends directly above the emulsification cylinder 12 to ensure that the stirring structure can move up and down along the axis of the emulsification cylinder 12 and maintain a good correspondence with the material inside the emulsification cylinder 12.
[0026] Four fixing rods 23 are evenly fixed on the front side of the lower surface of the horizontal plate 22. The four fixing rods 23 are used to synchronously guide and support the stirring assembly and the sealing assembly to ensure stability during the lifting process. A sealing height adjustment mechanism 3 is installed on the surface of the four fixing rods 23. The sealing height adjustment mechanism 3 is used to form an effective seal on the top of the emulsifying cylinder 12 during the lifting process of the stirring structure to prevent external impurities from entering and reduce material volatilization. The sealing height adjustment mechanism 3 rises and falls together with the fixing rods 23 and seals the top of the emulsifying cylinder 12, thereby solving the problem of easy failure of the sealing structure when the stirring height is adjusted in the prior art.
[0027] The sealing height adjustment mechanism 3 includes a sealing cover plate 31 adapted to the top opening of the bottom plate 11. The sealing cover plate 31 is used to cover the top opening of the emulsifying cylinder 12 to form an integral sealing structure. An adjustment ring 35 is rotatably installed at the center of the surface of the sealing cover plate 31. The adjustment ring 35 is used to achieve detachable fixation between the sealing cover plate 31 and the fixing rod 23 under different stirring height states. The adjustment ring 35 connects and fixes the sealing cover plate 31 and the fixing rod 23 by rotation, thereby achieving the adjustment of the stirring height while ensuring that the sealing state is not damaged.
[0028] The sealing cover plate 31 is provided with a multi-point dripping mechanism 4. The multi-point dripping mechanism 4 is used to solve the problem of uneven dispersion of the aqueous phase and low emulsification efficiency caused by single-point water addition in the prior art. The multi-point dripping mechanism 4 is used to uniformly add liquid to the inside of the emulsification cylinder 12 through multiple points during emulsification, so that the aqueous phase is quickly dispersed in the oil phase to improve the emulsification uniformity and emulsification efficiency.
[0029] Referring to Figures 1-3, a stirring frame 24 is provided at the bottom of the four fixed rods 23. The stirring frame 24 is used to form a limited stirring area for the material inside the emulsifying cylinder 12 to enhance the shearing and mixing effect. The stirring frame 24 is placed on the central axis inside the emulsifying cylinder 12 to ensure uniform stirring force and avoid eccentric stirring. A drive mechanism 221 is installed on the surface of the horizontal plate 22. The drive mechanism 221 is used to provide the rotational power required for stirring. A stirring shaft 25 is provided downward at the output end of the drive mechanism 221. The stirring shaft 25 is used to transmit the power of the drive mechanism 221 to the inside of the emulsifying cylinder 12. The stirring shaft 25 is placed between the four fixed rods 23 to maintain stable guidance during lifting. A blade 26 is fixed at the bottom of the stirring shaft 25. The blade 26 is used to generate shearing, turning and mixing effects on the material during rotation. The blade 26 is placed inside the stirring frame 24 to efficiently stir the material within a limited space.
[0030] Referring to Figures 1-3, four limiting blocks 36 are evenly arranged on the inner wall of the adjusting ring 35. The limiting blocks 36 are used to limit the fixed rod 23 at different height positions to achieve the height fixation of the sealing cover 31. The surface of the fixed rod 23 is evenly provided with limiting grooves 231 along the axis. The limiting grooves 231 are used to form corresponding cooperation with the limiting blocks 36 at different height positions. The internal dimensions of the limiting blocks 36 and the limiting grooves 231 are adapted to each other. By controlling the cooperation of the limiting blocks 36 with the limiting grooves 231 at different heights, the sealing end cover 31 is fixed, thereby achieving stable operation of the stirring frame 24 at different liquid levels inside the emulsifying cylinder 12.
[0031] Referring to Figures 1-6, the adjusting ring 35 is positioned outside the four fixed rods 23. The adjusting ring 35 is used to simultaneously drive the four limit blocks 36 to complete synchronous position switching during rotation. An outer extension plate 37 is symmetrically arranged on the outer surface of the adjusting ring 35. The outer extension plate 37 is used to provide an installation base for the positioning structure. A positioning bolt 38 is vertically slidably installed on the surface of the outer extension plate 37. The positioning bolt 38 is used to lock the adjusting ring 35 after adjustment. An arc-shaped track groove 34 is symmetrically opened on the surface of the sealing cover plate 31. The arc-shaped track groove 34 is used to limit the rotation angle range of the adjusting ring 35 to prevent misoperation. The end of the positioning bolt 38 is placed inside the arc-shaped track groove 34 to limit the rotation angle of the adjusting ring 35. Both ends of the bottom of the arc-shaped track groove 34 are provided with internal threaded holes 341. The internal threaded holes 341 are used to engage with and fix the positioning bolt 38. The end of the positioning bolt 38 is engaged inside the internal threaded hole 341 to fix the adjusting ring 35.
[0032] Referring to Figures 7-8, the multi-point dripping mechanism 4 includes an arc-shaped channel 41 fixed to the upper surface of the sealing cover plate 31. The arc-shaped channel 41 is used to distribute the incoming liquid. At least three vertical droppers 42 are evenly arranged on the surface of the arc-shaped channel 41. The vertical droppers 42 are used to form multiple independent dripping points to improve the dispersion effect of the aqueous phase. The vertical droppers 42 are connected to the inside of the arc-shaped channel 41. The hollow bottom of the vertical droppers 42 is connected to the emulsification cylinder 12 to realize liquid dripping. A dripping tank 32 and a feeding port 33 are respectively arranged on the front side of the sealing cover plate 31. The dripping tank 32 is used to store the aqueous phase liquid to be dripped. The feeding port 33 is used to add animal and vegetable oils, mineral oils and emulsifiers into the emulsification cylinder 12. The dripping tank 32 is connected to the inside of the arc-shaped channel 41 through a hose to realize liquid transportation.
[0033] A cap 43 is screwed onto the top of the vertical dropper 42. The cap 43 is used to seal the top of the vertical dropper 42 and serves as the mounting point for the sliding component. A slide rod 44 is vertically slidably mounted on the surface of the cap 43. The slide rod 44 is used to control the dripping on and off. The slide rod 44 passes through the vertical dropper 42. The diameter of the slide rod 44 is smaller than the inner hole size of the vertical dropper 42 to ensure smooth sliding. A stopper 45 is provided at the bottom of the slide rod 44. The stopper 45 is used to block the bottom outlet of the vertical dropper 42. The stopper 45 slides upward to block the bottom outlet of the vertical dropper 42 to achieve the dripping closed state.
[0034] Referring to Figures 7-8, a control ring 47 is suspended at the top of the arc-shaped channel 41. The control ring 47 is used to synchronously control multiple sliding rods 44. The tops of the multiple sliding rods 44 are all screwed onto the lower surface of the control ring 47 to achieve linkage. A spring 46 is sleeved on the surface of the sliding rod 44. The spring 46 is used to provide a restoring force in the non-drip state. The spring 46 is placed between the top of the vertical dropper 42 and the control ring 47. The spring 46 applies an upward thrust to the control ring 47 to keep the stopper 45 in a sealed state. Support plates 39 are fixed on both sides of the sealing cover plate 31. The support plates 39 are used to provide a rotation fulcrum for the drive mechanism. A horizontal crossbar is rotatably installed between the two support plates 39. The lever 48 and the crossbar 48 are used to convert the linear motion of the cylinder into a pressing action. Both ends of the surface of the crossbar 48 are provided with eccentric pressing blocks 481. The eccentric pressing blocks 481 are used to apply downward pressing force to the control ring 47 when the crossbar 48 swings. The two eccentric pressing blocks 481 contact the two sides of the upper surface of the control ring 47 respectively to ensure balanced force. The center of the crossbar 48 is provided with a U-shaped bend 482. The U-shaped bend 482 is used to bypass the fixed rod 23 and connect to the control cylinder 49. The control cylinder 49 is hinged to the rear side of the surface of the sealing cover plate 31. The control cylinder 49 is used to drive the crossbar 48 to swing back and forth. The output end of the control cylinder 49 is installed on the U-shaped bend 482.
[0035] Referring to Figures 1-4, an outlet pipe 13 is provided at the bottom of the emulsifying cylinder 12. The outlet pipe 13 is used to discharge the separating agent after emulsification. A control valve is installed inside the outlet pipe 13 to control the start and stop of the discharge and the flow rate. The end of the outlet pipe 13 extends beyond the range of the outlet pipe 13 to facilitate connection to an external conveying pipeline. Heating rods 14 are evenly arranged on the inner wall of the emulsifying cylinder 12. The heating rods 14 are used to heat the material inside the emulsifying cylinder 12 and maintain the temperature conditions required for emulsification.
[0036] An environmentally friendly asphalt release agent preparation method mainly includes the following steps: S1, mixing: animal and vegetable oils, mineral oils, and emulsifiers are added to a high-speed homogenizing emulsifier in a specific ratio for mixing. The problem of uneven initial mixing between the oil phase and the emulsifier is solved by controlling the temperature and speed. The high-speed homogenizing emulsifier is set to a specific temperature, the heating device is turned on, and high-speed homogenization is performed for a certain period of time.
[0037] S2: Emulsification: After the materials in S1 are mixed evenly, in order to address the problem of low emulsification efficiency of traditional single-point water addition, pure water at a specific temperature is added dropwise to a high-speed homogenizing emulsifier according to a specific ratio, and the water is continuously added, stirred and emulsified. After completion, emulsification continues for a certain period of time.
[0038] S3: Thickening: After the material emulsification is complete, in order to improve the stability of the release agent and the anti-settling performance, a certain proportion of anti-settling thickening agent is added, and high-speed homogenization emulsification is continued for 5-60 minutes.
[0039] S4: Grinding: The mixed material from step S3 is fed into a ball mill for fine grinding and emulsification to further refine the particle size and improve adhesion performance. The ball mill speed is 500-1000 r / min to obtain the release agent.
[0040] S1 contains one or more of the following: animal and vegetable oils; refined kitchen waste oil; palm oil; soybean oil; moringa oil; rapeseed oil; corn oil; sunflower oil; lard; tallow; and mutton tallow. Mineral oils contain one or more of the following: aromatic oils; naphthenic oils; paraffin oils; silicone oils; and cutting oils. Emulsifiers are one or more of the following: sodium dodecylbenzene sulfonate; sodium dodecyl sulfate; sorbitan monostearate; polyoxyethylene sorbitan monooleate; polyoxyethylene sorbitan monostearate; alkylphenol polyoxyethylene ethers; sorbitan monooleate; sodium aluminate; polyethylene glycol; polyvinyl alcohol; polyacrylates; and fatty alcohol polyoxyethylene ethers. The high-speed homogenizing emulsifier operates at a speed of 500–3000 r / min; the mixing temperature is 20–100℃; and the mixing time is 5–60 min.
[0041] In S2, the mass fraction of purified water is 50-90 parts, the temperature is 20-100℃, the dropping rate is 1-100 L / min, and the emulsification time is 5-60 min; the anti-settling and thickening agent in S3 is one or more compounds selected from sodium carboxymethyl cellulose, sodium hydroxymethyl cellulose, sodium hydroxypropyl cellulose, gum arabic, guar gum, xanthan gum, sodium alginate, and guar gum. Example
[0042] Referring to Figures 1, 2, and 3, in this embodiment, the emulsification mechanism includes a base plate 11, an emulsification cylinder 12, a lifting and stirring structure 2, and a sealing height adjustment mechanism 3. The hydraulic cylinder 21 in the lifting and stirring structure 2 is an industrial hydraulic cylinder of model HSGK-80-300. The top of the hydraulic cylinder 21 is connected to a horizontal plate 22, and the stirring frame 24 and the sealing cover plate 31 are driven to rise and fall synchronously through four fixed rods 23 below the horizontal plate 22.
[0043] During the emulsification process, when the material level is high or the viscosity is high, the hydraulic cylinder 21 moves downward, causing the stirring frame 24 to penetrate into the bottom area of the emulsification cylinder 12, thereby enhancing the shearing effect on the high-viscosity material. At the same time, the sealing cover 31 is always in contact with the top of the emulsification cylinder 12 to prevent external impurities from entering.
[0044] Compared to traditional emulsification devices that use a fixed-height stirring structure with the stirring shaft passing directly through the top of the cylinder, the top sealing gasket is prone to loosening when adjusting the stirring height, leading to material evaporation and dust ingress. This embodiment effectively avoids these problems through synchronous lifting and an overall sealing structure, verifying the feasibility of the structure. Example
[0045] Referring to Figures 1, 3, and 4, multiple sets of limiting grooves 231 are machined along the axis on the surface of the fixed rod 23. A limiting block 36 is set on the inner wall of the adjusting ring 35. The limiting block 36 is made of 304 stainless steel. The limiting grooves 231 are formed by CNC milling.
[0046] In actual production, by rotating the adjusting ring 35, the limiting block 36 is made to cooperate with the limiting groove 231 of different heights, thereby fixing the sealing cover plate 31 and the stirring frame 24 at different height positions, so that the stirring frame 24 can work stably in the lower, middle or upper layer of the emulsifying cylinder 12, to meet the emulsification requirements of different formulation systems.
[0047] Compared to lifting and stirring devices without height limiting structures, where the stirring components are prone to height drift due to vibration during stirring, this embodiment significantly improves stirring stability through the rigid fit between the limiting block 36 and the limiting groove 231. (Example)
[0048] Referring to Figures 1, 5, and 6, an outer extension plate 37 is provided on the outer side of the adjusting ring 35. A positioning bolt 38 is vertically slidably installed on the outer extension plate 37. The positioning bolt 38 is a stainless steel fastener of model M12×1.75-40. The arc-shaped track groove 34 has internal threaded holes 341 machined at both ends.
[0049] After the stirring height is adjusted, the positioning bolt 38 slides along the arc-shaped track groove 34 to the position of the internal threaded hole 341 and is tightened, thereby reliably locking the adjusting ring 35 and preventing accidental rotation during the stirring process.
[0050] Compared to structures that rely solely on friction to fix the adjusting ring, which are prone to loosening after prolonged stirring, this embodiment significantly improves the reliability of the adjusting position through a mechanical locking method. (Example)
[0051] Referring to Figures 7 and 8, the multi-point dripping mechanism 4 includes an arc-shaped channel 41 and at least three vertical droppers 42. The vertical droppers 42 are made of heat-resistant polytetrafluoroethylene tubing, and the dripping tank 32 is connected to the arc-shaped channel 41 through a pressure-resistant hose.
[0052] During the emulsification process, the aqueous phase enters the arc-shaped channel 41 from the dripping tank 32, and then is simultaneously dripped into the emulsification cylinder 12 by multiple vertical droppers 42, so that the aqueous phase forms a multi-point dispersion state in the oil phase, thereby significantly improving the emulsification speed and uniformity.
[0053] Compared to the single-droplet water addition method, where the aqueous phase is concentrated in a localized area, this embodiment utilizes a multi-point dripping structure to achieve a more uniform aqueous phase distribution and significantly shorten the emulsification time. Example
[0054] Referring to Figures 7 and 8, the tops of multiple slide rods 44 are screwed onto the lower surface of the control ring 47. Springs 46 are installed on the outer side of the slide rods 44. Springs 46 are stainless steel compression springs with an elastic coefficient of 5 N / mm. The control cylinder 49 is a standard cylinder of model SC-50×100.
[0055] When the control cylinder 49 is activated, the control ring 47 is pressed synchronously by the crossbar 48 and the eccentric extrusion block 481, causing multiple plugs 45 to open simultaneously, achieving multi-point synchronous dripping and ensuring consistent liquid output at each dripping point.
[0056] Compared to structures where each dropper is controlled independently, inconsistent liquid output can easily occur. This embodiment, through a centralized, interconnected control structure, effectively ensures consistent dripping. (Embodiment Example)
[0057] Referring to Figures 1 and 4, multiple heating rods 14 are evenly arranged on the inner wall of the emulsifying cylinder 12. The heating rods 14 are 220V / 2kW stainless steel electric heating rods. The internal temperature of the emulsifying cylinder 12 is maintained within the range of 20 to 100℃ by the temperature control system, so that the animal and vegetable oils, mineral oils and emulsifiers are always in a suitable emulsification state.
[0058] Compared to emulsification devices without heating rods, the emulsification effect fluctuates significantly with changes in ambient temperature. This embodiment improves the stability of the emulsification process and the consistency of the finished product through a built-in heating structure. The working principle of this invention is as follows: Vegetable and animal oils, mineral oils, and emulsifiers are placed in a certain proportion inside the emulsification cylinder 12 through the feeding port 33. The cylinder 12 is then heated by the heating rod 14 to maintain a certain temperature for the internal materials. The hydraulic cylinder 21 controls the raising and lowering of the horizontal plate 22, which in turn controls the raising and lowering of the fixed rod 23 and the stirring shaft 25, thereby controlling the height of the stirring frame 24. The stirring frame 24 is immersed in the liquid to maintain a certain liquid level for thorough mixing of the internal materials. The sealing height adjustment mechanism 3 maintains a seal on the top of the emulsification cylinder 12 to prevent contamination of the internal materials. Then, a suitable amount of warm water is injected into the dripping tank 32, and the mixture is further mixed through multiple points. The dripping mechanism 4 drips into the emulsifying cylinder 12 at multiple points to achieve emulsification. During use, the bottom of the positioning bolt 38 is always positioned inside the arc-shaped track groove 34 to limit the rotation angle of the adjusting ring 35. The positioning bolt 38 controls the rotation of the adjusting ring 35, thereby controlling whether multiple limit blocks 36 engage with their corresponding limit grooves 231. Whether fully engaged or completely disengaged, they are held in place by the engagement of the positioning bolt 38 and the internal threaded hole 341. By controlling the engagement of the limit blocks 36 with the limit grooves 231, the distance between the stirring frame 24 and the sealing cover plate 31 is adjusted. This allows the stirring frame 24 to be positioned within the emulsifying cylinder 12 when the sealing cover plate 31 seals the top of the emulsifying cylinder 12. The depth of the liquid level is adjusted to adapt to emulsification production at different liquid levels. When the material viscosity is high, the stirring frame 24 is placed at the bottom of the liquid level; conversely, when the material viscosity is low, the stirring frame 24 is placed in the upper middle layer of the liquid level to ensure emulsification effect. After a single production cycle, the sealing cover 31 can be opened by lifting the fixing rod 23 to facilitate internal cleaning. The liquid is placed inside the dripping tank 32 and transported through a hose to fill the arc-shaped channel 41. Under normal conditions, due to the pushing force of the spring 46 on the control ring 47, the control ring 47 is placed at the top, which in turn controls multiple sliding rods 44 to be placed at the top of their stroke. At this time, the stopper 45 can seal the bottom of the vertical dripping tube 42. During dripping, the cylinder 4 is controlled. 9. The U-shaped bend 482 can be reciprocated to make the crossbar 48 swing back and forth within a certain angle. The U-shaped bend 482 is used to bypass the central fixed bar 23. When the crossbar 48 swings back and forth, the control ring 47 can be pressed by the eccentric extrusion block 481. The eccentric extrusion blocks 481 on both sides are installed on the control ring 47 at the same time, which can make the control ring 47 move down stably, and then squeeze and store the spring 46. When the control ring 47 is pressed down, it can control multiple plugs 45 to no longer block the bottom of the vertical dropper 42, thereby realizing multi-point dripping. The amount and frequency of multi-point dripping are controlled by the control cylinder 49. This structure can disperse the liquid into the emulsification cylinder 12 through multi-point dripping, thereby improving the emulsification effect.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention are implemented according to conventional methods in the art unless otherwise specified or limited.
