Description

Technical Field

[0001] This invention relates to the field of finishing agent preparation equipment technology, specifically a microemulsion preparation device for organosilicon finishing agents. Background Technology

[0002] Organosilicon finishing agents are widely used in the field of textile softening and smoothing finishing. Their microemulsion preparation process is a key factor that determines the performance of the product. During the microemulsion process, the method of adding water and pH control directly affect the particle size distribution, uniformity and storage stability of the emulsion.

[0003] In existing technologies, the microemulsion preparation device for organosilicon finishing agents typically uses a stirring paddle to mix raw materials such as silicone oil and emulsifiers, and then adds water to the tank through pipelines. However, the existing device has the following shortcomings:

[0004] 1. Existing devices often use single-point or a small number of inlets to directly inject pure water into the preparation tank. Due to the high viscosity of the organosilicon oil phase, the addition of water can easily lead to an excessively high water-oil ratio in local areas, causing the emulsion in that area to gel, separate, or demulsify. Even with mixing by a stirring paddle, the elimination of the local concentration gradient is still delayed, making it difficult to achieve a uniform phase transition process, which ultimately affects the particle size uniformity and long-term stability of the microemulsion.

[0005] 2. During the microemulsion process, the pH value of the system has a significant impact on the stability of the emulsion. Existing devices require operators to manually sample, test, and add adjusting solution. This method has drawbacks such as response lag and large human error, which can easily cause excessive pH fluctuations, leading to emulsion demulsification or performance degradation. At the same time, manual adjustment interrupts the continuity of the preparation process and reduces preparation efficiency. Summary of the Invention

[0006] In view of the above-mentioned shortcomings in the existing technology, the purpose of this invention is to provide a microemulsion preparation device that improves the uniformity and stability of the microemulsion process of organosilicon finishing agents.

[0007] The technical solution adopted by the present invention to achieve the above objectives is: a microemulsion preparation device for an organosilicon finishing agent, comprising a device frame and a preparation tank fixedly connected to the device frame, a stirring paddle rotatably connected to the preparation tank, a stirring motor fixedly connected to the preparation tank, the stirring motor being poweredly connected to the stirring paddle, an intermittent water supply mechanism being provided inside the preparation tank, and a power on / off control mechanism being provided on the preparation tank, wherein the stirring motor can transmit power to or disconnect from the intermittent water supply mechanism through the power on / off control mechanism, so that the intermittent water supply mechanism can intermittently add water to or not add water to the preparation tank;

[0008] The device frame is also equipped with a pH adjustment mechanism, which cooperates with the pipeline of the preparation tank. The stirring motor can transmit or disconnect power to the pH adjustment mechanism through the power on / off control mechanism, so that the pH adjustment mechanism can add the adjustment liquid to the preparation tank or not add it. When the power on / off control mechanism transmits power to the pH adjustment mechanism, the power on / off control mechanism is disconnected from the interval water supply mechanism. When the power on / off control mechanism transmits power to the interval water supply mechanism, the power on / off control mechanism is disconnected from the pH adjustment mechanism.

[0009] In one embodiment, the interval water supply mechanism is implemented using the following structure:

[0010] The interval water supply mechanism includes a chassis, a rotating disk, a top disk, and a drive component. The chassis is fixedly connected to the top of the preparation tank. The chassis has multiple sets of water outlets A. The rotating disk is rotatably connected inside the chassis. The bottom surface of the rotating disk abuts against the inner bottom surface of the chassis. The bottom surface of the rotating disk has multiple sets of water outlets B. Water outlets A and B correspond one-to-one. The top disk is rotatably connected to the top surface of the rotating disk. The top disk is fixedly connected inside the preparation tank. A water supply pipe is fixedly connected to the top disk. The water supply pipe communicates with the interior of the rotating disk and extends out of the preparation tank.

[0011] The preparation tank is equipped with a drive component that is poweredly connected to the rotating disk, and the drive component cooperates with the power on / off control mechanism;

[0012] Furthermore, the chassis, rotating disk, and top disk are coaxially arranged with the stirring paddle, and the water outlet A and the water outlet B are arranged in a circular array with the axis of the stirring paddle as the center.

[0013] The chassis, rotating disk, and top disk are all provided with shaft holes for the impeller shaft that mates with the stirring paddle. The impeller shaft passes through the shaft hole, and the shaft hole and the impeller shaft are sealed by a sealing bearing.

[0014] Furthermore, the drive component adopts the following structure:

[0015] The driving component includes a fixed gear ring, a driving gear, and a driving shaft. The fixed gear ring is fixedly connected to the rotating disk. The preparation tank is provided with a driving port corresponding to the fixed gear ring. The driving shaft is rotatably connected to the outside of the preparation tank. The driving gear is fixedly connected to the driving shaft and meshes with the fixed gear ring.

[0016] The power on / off control mechanism cooperates with the drive shaft.

[0017] In one embodiment, the pH adjustment mechanism has the following structure:

[0018] The pH adjustment mechanism includes a pH sensor, an adjustment tank, and a passive pump. The adjustment tank is fixedly connected to the device frame, and the passive pump is fixedly connected to the preparation tank. The adjustment tank and the inlet of the passive pump are connected through a pipeline. A filling head is fixedly connected to the preparation tank, and the filling head is connected to the outlet of the passive pump through a pipeline. A flow meter is installed on the pipeline, and the pH sensor is fixedly connected to the preparation tank.

[0019] The pump shaft of the powerless pump body cooperates with the power on / off control mechanism.

[0020] In one embodiment, the power on / off control mechanism specifically comprises a drive source, an on / off mechanism A, and an on / off mechanism B. The on / off mechanism A is provided on the preparation tank in cooperation with the pump shaft, and the on / off mechanism B is provided on the preparation tank in cooperation with the drive shaft. The drive source is provided on the device frame, and the drive source cooperates with the on / off mechanism A and the on / off mechanism B. The drive source can drive the on / off mechanism A to disconnect or transmit power from the pump shaft, and the drive source can drive the on / off mechanism B to transmit or disconnect power from the drive shaft.

[0021] Furthermore, the structure of the switching mechanism A is as follows:

[0022] The switching mechanism A includes an active friction wheel, a driven friction wheel A, and an intermediate friction wheel A. The driven friction wheel A is fixedly connected to the pump shaft, and the active friction wheel is fixedly connected to the impeller shaft of the stirring paddle. A lifting platform A is slidably connected to the preparation tank between the active friction wheel and the driven friction wheel A. The intermediate friction wheel A is rotatably connected to the lifting platform A. The lifting platform A cooperates with the driving source component, and the driving source component can drive the lifting platform A to rise and fall, so that the intermediate friction wheel A abuts against or moves away from the active friction wheel and the driven friction wheel A.

[0023] Furthermore, the specific structure of the switching mechanism B is as follows:

[0024] The switching mechanism B includes a driven friction wheel B and an intermediate friction wheel B. The driven friction wheel B is fixedly connected to the drive shaft. A lifting platform B is slidably connected to the preparation tank between the driven friction wheel B and the driven friction wheel. The intermediate friction wheel B is rotatably connected to the lifting platform B. The lifting platform B cooperates with the drive source component, which can drive the lifting platform B to rise and fall, so that the intermediate friction wheel B abuts against or moves away from the driven friction wheel B and the driven friction wheel B.

[0025] Furthermore, the specific structure of the driving source component is as follows:

[0026] The drive source component includes a lever arm, a traction arm, and a drive component. The lever arm is rotatably connected to the device frame between the lifting platform A and the lifting platform B via a lever shaft.

[0027] The lever arm located on one side of the lever axis is the driving side A, and the lever arm located on the other side of the lever axis is the driving side B;

[0028] Both drive side A and drive side B are provided with guide grooves, and both lifting platform A and lifting platform B are fixedly connected with traction arms. Each set of traction arms is fixedly connected with a roller shaft at its top.

[0029] One set of the rollers is located in an adjacent guide groove, and another set of the rollers is located in another guide groove;

[0030] The device frame is equipped with the drive component that works in conjunction with the lever arm. The drive component can drive the lever arm to rotate around the lever axis.

[0031] In one embodiment, the aforementioned driving component is a telescopic cylinder, which is rotatably connected to the device frame, and the piston end of the telescopic cylinder is rotatably connected to the lever arm.

[0032] The beneficial effects of this invention are:

[0033] 1. The stirring motor can drive the stirring paddle, which mixes the raw materials (amino silicone oil, compounded emulsifier, co-emulsifier) ​​inside the preparation tank. The power on / off control mechanism prevents the power from being transmitted to the interval water supply mechanism and the pH adjustment mechanism, thereby ensuring the normal mixing of raw materials in the early stage.

[0034] After the above raw materials have been mixed and stirred for a predetermined time, the power on / off control mechanism can be selectively connected to the pH adjustment mechanism, so that the power of the stirring motor can be transmitted to the pH adjustment mechanism, thereby adjusting the pH of the mixed raw materials in the preparation tank through the pH adjustment mechanism.

[0035] In addition, the power on / off control mechanism can selectively transmit power to the intermittent water supply mechanism, which then adds water to the preparation tank intermittently to achieve microemulsification.

[0036] The above structure can provide the necessary power to the interval water supply mechanism and pH adjustment mechanism through a set of stirring motors, reducing the number of motors and electrical control components, reducing equipment manufacturing costs and failure points. In addition, the power on / off control mechanism can only transmit the power of the stirring motor to one of the interval water supply mechanism or pH adjustment mechanism at the same time, and cannot transmit it simultaneously. This fundamentally avoids adding pH adjustment liquid while adding water, preventing local concentration changes, emulsion demulsification, or pH overshoot. This is a pure mechanical interlock, which is more reliable than software or relay interlock and does not rely on program logic.

[0037] 2. This intermittent water supply mechanism adopts a three-layer coaxial stacked structure of chassis, rotating disk and top disk. The chassis is equipped with multiple sets of water outlets A, and the bottom surface of the rotating disk is equipped with multiple sets of corresponding water outlets B. When the power on / off control mechanism drives the rotating disk to rotate through the drive component, water will flow into the preparation tank through the water supply pipe and inside the rotating disk only when water outlets A and B rotate to the same position. If they are misaligned, the flow will be automatically blocked, thus realizing a purely mechanical intermittent water supply without the need for solenoid valves. It has good stability. At the same time, all water outlets are arranged in a circular array with the axis of the stirring paddle as the center. When water is added, water drips in from multiple circumferential points at the same time. With the stirring of the central stirring paddle, it can effectively avoid the risk of uneven emulsion dilution or gelation caused by local water concentration, and significantly improve the uniformity and stability of the microemulsion process of organosilicon finishing agent.

[0038] 3. The pH value in the preparation tank can be detected by the pH sensor. When pH adjustment is required, the power on / off control mechanism can transmit power to the pump body, which pumps the adjustment liquid into the preparation tank. The flow rate is detected by the flow meter, thereby realizing automatic pH adjustment. When the mixed raw materials reach the predetermined pH value, the stability of the emulsion can be significantly improved, and the tediousness of manual adjustment can be reduced.

[0039] 4. This power on / off control mechanism uses a single drive source (telescopic cylinder) to drive the lever arm to rotate around the lever axis. The guide grooves on both sides of the lever arm drive the lifting platform A and lifting platform B to move in opposite directions through rollers and traction arms, thereby selectively engaging or disengaging the intermediate friction wheel A or intermediate friction wheel B rotatably connected to the lifting platform with the active friction wheel and the corresponding driven friction wheel A or driven friction wheel B. This achieves mechanical interlocking switching of the stirring motor power between the water supply and pH adjustment paths, and only one path can transmit power at a time. Furthermore, the friction wheel transmission method allows for a slight slippage at the moment of switching, effectively buffering the impact when power is connected and disconnected, and protecting the stirring motor and the end actuator (such as the rotary disc drive gear and the powerless pump body).

[0058] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0059] Example 1

[0060] Please see Figures 1-9 A microemulsion preparation device for an organosilicon finishing agent includes a device frame 100 and a preparation tank 200 fixedly connected to the device frame 100. A stirring paddle 301 is rotatably connected to the preparation tank 200, and a stirring motor 302 is fixedly connected to the preparation tank 200. The stirring motor 302 is poweredly connected to the stirring paddle 301. The stirring motor 302 is used to drive the stirring paddle 301 to rotate, so as to mix and stir the raw materials such as amino silicone oil, compounded emulsifier, and co-emulsifier in the preparation tank 200.

[0061] The preparation tank 200 is equipped with an intermittent water supply mechanism 400 and a power on / off control mechanism 500. The stirring motor 302 can transmit or disconnect power to the intermittent water supply mechanism 400 through the power on / off control mechanism 500, so that the intermittent water supply mechanism 400 can intermittently add water to the preparation tank 200 or not add water.

[0062] The device frame 100 is also equipped with a pH adjustment mechanism 600. The pH adjustment mechanism 600 is connected to the pipeline of the preparation tank 200. The stirring motor 302 can transmit power to or disconnect from the pH adjustment mechanism 600 through the power on / off control mechanism 500, so that the pH adjustment mechanism 600 can add the adjustment liquid to the preparation tank 200 or not add it.

[0063] It should be noted that when the power on / off control mechanism 500 transmits power to the pH adjustment mechanism 600, the power on / off control mechanism 500 is disconnected from the intermittent water supply mechanism 400.

[0064] When the power on / off control mechanism 500 transmits power to the interval water supply mechanism 400, the power on / off control mechanism 500 disconnects from the pH adjustment mechanism 600. This design achieves a purely mechanical interlock, ensuring that the two operations of adding water and adding pH adjustment liquid are absolutely mutually exclusive in terms of timing.

[0065] The core mechanism of this embodiment will be described in detail below.

[0066] First of all, please refer to Figure 3 , Figures 7-9 The interval water supply mechanism 400 includes a chassis 401, a rotating disk 402, a top disk 403, and a drive component 404. The chassis 401 is fixedly connected to the inner top of the preparation tank 200. Multiple sets of water outlets A4011 are provided on the chassis 401. The rotating disk 402 is rotatably connected inside the chassis 401. The bottom surface of the rotating disk 402 abuts against the inner bottom surface of the chassis 401. Multiple sets of water outlets B4021 are provided on the bottom surface of the rotating disk 402. Water outlets A4011 and B4021 correspond one-to-one. The top disk 403 is rotatably connected to the top surface of the rotating disk 402. The top disk 403 is fixedly connected inside the preparation tank 200. A water supply pipe 405 is fixedly connected to the top disk 403. The water supply pipe 405 communicates with the inside of the rotating disk 402 and extends out of the preparation tank 200 for connection to an external water source.

[0067] In addition, the chassis 401, rotating disk 402 and top disk 403 are all coaxially arranged with the agitator 301. The water outlet A4011 and water outlet B4021 are arranged in a ring array with the axis of the agitator 301 as the center. The shaft of the agitator 301 on the chassis 401, rotating disk 402 and top disk 403 is provided with shaft hole 406. The shaft of the agitator 301 passes through the shaft hole 406. The shaft hole 406 and the shaft are sealed by a sealing bearing to prevent water from leaking along the shaft.

[0068] The drive component 404 is mounted on the preparation tank 200 and is poweredly connected to the rotating disk 402. The drive component 404 also cooperates with the power on / off control mechanism 500. Specifically, the drive component 404 includes a fixed gear ring 4041, a drive gear 4042, and a drive shaft 4043. That is, the fixed gear ring 4041 is fixedly connected to the rotating disk 402, and a drive port 201 is opened on the preparation tank 200 at the position corresponding to the fixed gear ring 4041. The drive shaft 4043 is rotatably connected to the outside of the preparation tank 200, and the drive gear 4042 is fixedly connected to the drive shaft 4043. The drive gear 4042 passes through the drive port 201 and meshes with the fixed gear ring 4041. The power on / off control mechanism 500 cooperates with the drive shaft 4043 to control whether the power of the stirring motor 302 is transmitted to the drive shaft 4043.

[0069] When the power of the stirring motor 302 is transmitted to the drive shaft 4043 through the power on / off control mechanism 500, the drive shaft 4043 drives the drive gear 4042 to rotate, the drive gear 4042 drives the fixed gear ring 4041 to rotate, and the fixed gear ring 4041 drives the rotating disk 402 to rotate relative to the base plate 401 and the top plate 403. When the rotating disk 402 rotates to the position where the water outlet B4021 coincides with the water outlet A4011, the water that enters the rotating disk 402 from the water supply pipe 405 flows into the preparation tank 200 through the water outlet B4021 and the water outlet A4011 in sequence.

[0070] When the rotating disk 402 continues to rotate until the outlet B4021 and the outlet A4011 are misaligned, the water flow is blocked;

[0071] As the rotating disk 402 continues to rotate, intermittent, multi-point uniform water addition can be achieved. Water drips into the preparation tank 200 simultaneously from multiple circumferential points. Combined with the stirring of the central stirring paddle 301, the uniformity of water addition is significantly improved.

[0072] Secondly, please refer to Figures 4-6 The pH adjustment mechanism 600 includes a pH sensor 601, an adjustment tank 602, and a powerless pump 603. The adjustment tank 602 is fixedly connected to the device frame 100 for storing the adjustment liquid (such as acetic acid). The powerless pump 603 is fixedly connected to the preparation tank 200. The adjustment tank 602 and the inlet of the powerless pump 603 are connected through a pipeline. The preparation tank 200 is fixedly connected to a liquid filling head, which is connected to the outlet of the powerless pump 603 through a pipeline. A flow meter for detecting the flow rate is also provided on the above pipeline. The pump shaft of the powerless pump 603 cooperates with the power on / off control mechanism 500 to receive power from the stirring motor 302. The pH sensor 601 is also fixedly connected to the preparation tank 200 for real-time monitoring of the pH value of the material in the preparation tank 200.

[0073] When pH needs to be adjusted, the power on / off control mechanism 500 transmits the power of the stirring motor 302 to the pump shaft of the powerless pump body 603. The pump shaft rotates to drive the pump body to work, pumping out the adjusting liquid in the adjusting storage tank 602 and adding it into the preparation tank 200 through the liquid addition head. The amount added is detected by the flow meter. When the amount added reaches the required level, the power on / off control mechanism 500 disconnects the power transmitted by the stirring motor 302.

[0074] When adding conditioning fluid, the power on / off control mechanism 500 has disconnected the power transmission with the interval water supply mechanism 400, so the water addition operation stops, thus avoiding drastic local pH fluctuations caused by adding water while adding conditioning fluid.

[0075] Finally, please see Figures 4-6The power on / off control mechanism 500 includes a drive source 501, an on / off mechanism A502, and an on / off mechanism B503. Specifically, the on / off mechanism A502 is provided on the preparation tank 200 at a position that cooperates with the pump shaft of the pump body 603 without a power source, and is used to control whether the power of the stirring motor 302 is transmitted to the pump shaft. The on / off mechanism B503 is provided on the preparation tank 200 at a position that cooperates with the drive shaft 4043, and is used to control whether the power of the stirring motor 302 is transmitted to the drive shaft 4043. The device frame 100 is provided with a drive source 501, which cooperates with the on / off mechanism A502 and the on / off mechanism B503. It can drive the on / off mechanism A502 to disconnect or transmit power from the pump shaft, and at the same time, it can drive the on / off mechanism B503 to transmit or disconnect power from the drive shaft 4043.

[0076] Example 2

[0077] Please see Figure 6 , Figure 7 , Figures 10-12 A microemulsion preparation device for an organosilicon finishing agent is described in this embodiment, which further explains the power on / off control mechanism 500 based on Example 1.

[0078] Firstly, the switching mechanism A502 includes an active friction wheel 5021, a driven friction wheel A5022, and an intermediate friction wheel A5023. The active friction wheel 5021 is fixedly connected to the shaft of the stirring paddle 301, and the driven friction wheel A5022 is fixedly connected to the shaft of the pump body 603 without a power source. A lifting platform A5024 is slidably connected to the preparation tank 200 at a position corresponding to the position between the active friction wheel 5021 and the driven friction wheel A5022. The intermediate friction wheel A5023 is rotatably connected to the lifting platform A5024. The lifting platform A5024 cooperates with the drive source component 501, and the drive source component 501 can drive the lifting platform A5024 to rise and fall.

[0079] When the lifting platform A5024 descends, causing the intermediate friction wheel A5023 to simultaneously come into contact with and press against the active friction wheel 5021 and the driven friction wheel A5022, the power is transmitted from the impeller shaft of the stirring paddle 301 through the active friction wheel 5021 and the intermediate friction wheel A5023 to the driven friction wheel A5022, thereby driving the pump shaft to rotate.

[0080] When the lifting platform A5024 rises and the intermediate friction wheel A5023 moves away from both, the power is disconnected;

[0081] Secondly, the switching mechanism B503 includes a driven friction wheel B5031 and an intermediate friction wheel B5032. The driven friction wheel B5031 is fixedly connected to the drive shaft 4043. A lifting platform B5033 is slidably connected to the preparation tank 200 at a position between the driven friction wheel B5031 and the driving friction wheel 5021. The intermediate friction wheel B5032 is rotatably connected to the lifting platform B5033. The lifting platform B5033 cooperates with the drive source component 501, and the drive source component 501 can drive the lifting platform B5033 to rise and fall.

[0082] When the lifting platform B5033 descends, causing the intermediate friction wheel B5032 to simultaneously come into contact with and press against the active friction wheel 5021 and the driven friction wheel B5031, the power is transmitted from the impeller shaft of the stirring paddle 301 through the active friction wheel 5021 and the intermediate friction wheel B5032 to the driven friction wheel B5031, thereby driving the drive shaft 4043 to rotate, which in turn drives the rotating disk 402 to rotate to achieve intermittent water supply;

[0083] When the lifting platform B5033 rises and the intermediate friction wheel B5032 moves away from both, the power is disconnected.

[0084] Finally, the drive source component 501 includes a lever arm 5011, a traction arm 5012, and a drive component 5013. The lever arm 5011 is rotatably connected to the device frame 100 between the lifting platform A5024 and the lifting platform B5033 via a lever shaft. The lever arm 5011 is located on one side of the lever shaft as the drive side A and on the other side as the drive side B. Both drive side A and drive side B are provided with guide grooves 5014. The lifting platform A5024 and the lifting platform B5033 are fixedly connected with traction arms 5012. The top of each set of traction arms 5012 is fixedly connected with a roller shaft 5015. One set of roller shafts 5015 is located in the guide groove 5014 adjacent to it, and another set of roller shafts 5015 is located in another guide groove 5014. The device frame 100 is provided with a drive component 5013 in cooperation with the lever arm 5011. The drive component 5013 can drive the lever arm 5011 to rotate around the lever shaft.

[0085] In a preferred embodiment, the drive component 5013 is a telescopic cylinder, which is rotatably connected to the device frame 100, and the piston end of the telescopic cylinder is rotatably connected to the lever arm 5011.

[0086] Of course, the lever shaft can also be rotated by a motor to drive the lever arm 5011;

[0087] When the piston rod of the telescopic cylinder extends, the lever arm 5011 rotates around the lever axis, causing drive side A to rise and drive side B to fall, or vice versa. The specific direction depends on the installation position and connection relationship of the telescopic cylinder. Taking one working state as an example:

[0088] When the telescopic cylinder pushes the lever arm 5011 to lower the drive side A, the drive side A drives the traction arm 5012 and the lifting platform A5024 located on that side to lower through the guide slide 5014, so that the intermediate friction wheel A5023 abuts against the active friction wheel 5021 and the driven friction wheel A5022, realizing the power input of the pH adjustment mechanism 600. At the same time, the drive side B rises, driving the traction arm 5012 and the lifting platform B5033 on the other side to rise, so that the intermediate friction wheel B5032 separates from the active friction wheel 5021 and the driven friction wheel B5031, realizing the power disconnection of the interval water supply mechanism 400.

[0089] Conversely, when the telescopic cylinder drives the lever arm 5011 to rotate in the opposite direction, the water supply mechanism 400 is engaged while the pH adjustment mechanism 600 is disengaged, thus achieving a purely mechanical interlock between the two.

[0090] When the telescopic cylinder drives the lever arm 5011 to a horizontal or certain state, the intermediate friction wheel A5023 and intermediate friction wheel B5032 do not collide with the active friction wheel 5021. At this time, the pH adjustment mechanism 600 and the intermittent water supply mechanism 400 do not work.

[0091] The working process of the organosilicon finishing agent microemulsion preparation device provided in this embodiment is as follows:

[0092] In the initial state, the power on / off control mechanism 500 is in the middle position, that is, the intermediate friction wheel A5023 and the intermediate friction wheel B5032 are separated from the active friction wheel 5021, and the power of the stirring motor 302 only drives the stirring paddle 301 to rotate, and is not transmitted to the interval water supply mechanism 400 or the pH adjustment mechanism 600.

[0093] The operator adds amino silicone oil, compounded emulsifier, co-emulsifier and other raw materials into the preparation tank 200, starts the stirring motor 302, and the stirring paddle 301 mixes and stirs the above raw materials. At this time, the interval water supply mechanism 400 is in the closed state, that is, the water outlet A4011 and the water outlet B4021 are misaligned, and the pH adjustment mechanism 600 does not work.

[0094] Once the premixing reaches the predetermined time, water needs to be added for microemulsification. At this time, the telescopic cylinder is controlled to rotate the lever arm 5011, causing the lifting platform B5033 to descend. The intermediate friction wheel B5032 simultaneously contacts the active friction wheel 5021 and the driven friction wheel B5031. The power of the stirring motor 302 is transmitted to the drive shaft 4043, which in turn drives the rotating disk 402 to rotate. As the rotating disk 402 continues to rotate, the outlet B4021 and the outlet A4011 periodically overlap and misalign, realizing the intermittent, multi-point uniform addition of water to the preparation tank 200. The stirring paddle 301 continuously stirs, so that the water and oil phases are fully mixed to form a microemulsion.

[0095] The pH sensor 601 monitors the pH value inside the tank in real time. When the pH value of the system needs to be adjusted, the telescopic cylinder is controlled to move in the reverse direction, driving the lever arm 5011 to rotate in the reverse direction, causing the lifting platform B5033 to rise, disconnecting the power of the water supply mechanism 400, and at the same time, the lifting platform A5024 descends. The intermediate friction wheel A5023 simultaneously contacts the active friction wheel 5021 and the driven friction wheel A5022. The power of the stirring motor 302 is transmitted to the pump shaft of the passive pump body 603. The passive pump body 603 pumps the acid or alkali solution in the adjusting storage tank 602 into the preparation tank 200 until the pH value reaches the set range. Since the water addition operation has been mechanically interlocked at this time, water will not be added at the same time during the addition of the adjusting solution, thus avoiding drastic local pH fluctuations.

[0096] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
