Description

Technical Field

[0001] This invention relates to the field of emulsifier technology, specifically to an adaptive flow control vacuum emulsifier and its feeding method. Background Technology

[0002] A vacuum emulsifier is a high-performance mixing device that efficiently stirs, mixes, disperses, homogenizes, and emulsifies materials under vacuum conditions. It removes air bubbles from the material by vacuuming and, under vacuum or specific pressure / temperature conditions, uses a high-shear emulsifying head to uniformly and finely disperse one or more liquids or solid particles into another immiscible liquid, forming a stable emulsion or suspension.

[0003] When performing certain special processes, vacuum emulsifiers require the addition of other materials midway through the process (such as adding heat-sensitive ingredients or adjusting the formula). Currently, adding materials midway through the process typically involves a person wearing protective gear opening the feed inlet of the vacuum emulsifier. This manual addition requires weighing the materials and calculating the timing, which is cumbersome. Furthermore, the emulsifier continues to agitate the materials during addition, increasing the risk of splashing and scalding workers or causing leaks. Simultaneously, air continuously enters the emulsifier while the feed inlet is open, disrupting the vacuum environment and causing air bubbles to be introduced during agitation, potentially leading to product oxidation and spoilage, thus affecting product quality. Summary of the Invention

[0004] In view of this, the purpose of this invention is to provide an adaptive flow control vacuum emulsifier to solve the problems of existing equipment where, when adding materials midway, it is usually done manually by wearing protective gear and opening the feed port of the vacuum emulsifier. Manual feeding requires weighing the materials and calculating the timing, which is a cumbersome process. Furthermore, the emulsifier does not stop stirring the materials during feeding, which can easily cause materials to splash out and burn workers or lead to material leakage. At the same time, air continuously enters the emulsifier while the feed port is open, disrupting the vacuum environment and causing air bubbles to be introduced during stirring, or leading to product oxidation and deterioration, thus affecting product quality.

[0005] This invention is achieved through the following technical solution: An adaptive flow control vacuum emulsifier includes a vacuum mixing tank, a feed inlet, a storage tank, a feed valve, an automatic feeding device, and a controller. The vacuum mixing tank is used to mix materials. The feed inlet is located above the vacuum mixing tank. The storage tank is open at both ends and connected to the feed inlet, used to store the materials to be added. The end of the storage tank away from the feed inlet is connected to the automatic feeding device for automatic feeding. The feed valve is connected to the storage tank and used to close the storage tank. The controller is electrically connected to the feed valve and is used to control the opening and closing of the feed valve. The feed valve includes a first valve body and a second valve body. The first valve body is located at the end of the storage tank away from the vacuum mixing tank, and the second valve body is located at the end of the storage tank closer to the vacuum mixing tank. The space between the first valve body and the second valve body is used to store materials. The device also includes a vacuum pumping device. A vent is provided on the side wall of the storage tank away from the vacuum mixing tank and the vent is connected to the vacuum pumping device. The vacuum pumping device is electrically connected to the controller, and the controller is used to control the vacuum pumping device to evacuate the storage tank. The controller includes a process setting unit, a timing unit, and a metering unit. The process setting unit is used to input and set relevant processes, split the task data of the timing unit and the metering unit, and send the data to the timing unit and the metering unit respectively. The timing unit receives data from the process setting unit, performs timing under the corresponding time program, and sends the timing result to the control unit. The metering unit is used to receive data from the process setting unit, sense the amount of material entering the storage tank, and send the sensing result to the control unit. The control unit is used to receive signals from the timing unit or metering unit and control the opening and closing of the first valve body or the second valve body. At the same time, after the material is fed into the storage tank, it controls the vacuuming device to evacuate the storage tank.

[0006] Furthermore, a first rotating rod and a second rotating rod are respectively provided at the openings at both ends of the storage tank. Both the first rotating rod and the second rotating rod are rotatably connected to the storage tank and electrically connected to the control unit. The control unit is used to control the rotation of the rotating rod. The first valve body and the second valve body are connected to the first rotating rod and the second rotating rod in a one-to-one correspondence. It also includes a holding rod, a first cam, and a second cam. The side wall of the storage tank is hollow and forms a receiving cavity. One end of the first rotating rod and the second rotating rod both extend into the receiving cavity along their length direction. The holding rod is slidably disposed in the receiving cavity along the length direction of the storage tank. One end of the first rotating rod extending into the receiving cavity is connected to the first cam, and one end of the second rotating rod extending into the receiving cavity is connected to the second cam. The protrusions of the first cam and the second cam are both arranged along the length direction of the holding rod and perpendicular to the first valve body and the second valve body. One side of the first cam and the second cam, parallel to the length direction of the first rotating rod and the second rotating rod, contacts the side wall of the receiving cavity. The holding rod is located on the side of the first cam and the second cam opposite to the side of the receiving cavity sidewall, and the sides of both ends of the holding rod respectively contact the side of the first cam and the second cam opposite to the side of the receiving cavity sidewall.

[0007] Furthermore, the first valve body includes a first cover and a second cover, which can be closed to form an internally hollow cavity. Both the first cover and the second cover abut against the side wall of the storage tank. A connecting rod and a telescopic rod are provided between the first cover and the second cover. The two ends of the connecting rod are respectively connected to the first cover and the rotating rod. The base of the telescopic rod is connected to the rotating rod, and the output end is connected to the second cover. The surface of the second cover is provided with multiple air holes, which communicate with the interior of the storage tank and the cavity. The control unit includes an execution unit, a cleaning unit, and a vacuuming unit. The execution unit is used to control the opening and closing of the first valve body or the second valve body after receiving a signal from the timing unit or the metering unit. The vacuuming unit is electrically connected to the telescopic rod and the vacuuming device. The vacuuming unit is used to control the telescopic rod to extend to the lower edge of the vent and control the vacuuming device to perform vacuuming after the material tank is closed after feeding. The cleaning unit is electrically connected to the telescopic rod. The cleaning unit is used to push the telescopic rod to continue to extend when the second valve body is opened.

[0008] Furthermore, the output end of the telescopic rod is connected to a first scraper and a drive unit. The first scraper is rotatably connected to the second cover plate and abuts against the side of the second cover plate facing the vacuum mixing tank. The drive unit is used to drive the first scraper to rotate.

[0009] Furthermore, the drive unit includes a rotating part and a fan blade. The rotating part is rotatably connected to the second cover plate on both sides facing and away from the vacuum mixing tank. The fan blade is connected to the end of the rotating part away from the vacuum mixing tank, and the first scraper is connected to the end of the rotating part close to the vacuum mixing tank.

[0010] Furthermore, the rotating part has a bidirectional thread on the side away from the vacuum mixing tank in the middle, and also includes a sleeve, a slider, a support rod, and a vent needle. The sleeve is fitted onto the outer circumferential surface of the rotating part and can be slidably connected to the second cover along the length direction of the rotating part. The slider is connected inside the sleeve and can be slidably connected to the bidirectional thread. There are multiple support rods, which are arranged radially with the length direction of the rotating part as the center line and connected to the outer circumferential surface of the sleeve. Each vent needle is connected to one of the multiple support rods, and each vent needle corresponds to one of the multiple air ports.

[0011] Furthermore, the inner wall of the storage tank is recessed inward to form a groove. There are two grooves, and the two grooves face each other. It also includes a side wall cleaning mechanism. There are two sets of side wall cleaning mechanisms, and the two sets of side wall cleaning mechanisms correspond one to one of the two grooves. The side wall cleaning mechanism is used to clean the inner wall of the storage tank corresponding to the two sides of the second valve body when the second valve body is flipped. The side wall cleaning mechanism includes a sliding rod, a connecting block, an elastic element, and a second scraper. The second scraper abuts against the inner wall of the storage tank. The sliding rod is arranged along the length of the storage tank, and the end of the sliding rod facing the vacuum mixing tank is connected to the second scraper. One end of the connecting block is slidably connected to the groove, and the other end is connected to the second scraper. The elastic element is disposed in the groove, and the two ends of the elastic element are respectively connected to the side wall of the groove near the vacuum mixing tank and the second scraper.

[0012] A feeding method for an adaptive flow control vacuum emulsifier, using the aforementioned adaptive flow control vacuum emulsifier, includes the following steps: Step 1: Input the relevant process settings into the process setting unit, and split the task data of the timing unit and the metering unit through the process setting unit and send the data to the timing unit and the metering unit respectively; Step 2: When the equipment is started, the timing unit starts timing. The metering unit sends a signal to the control unit, causing the control unit to control the first valve to open the feed. The metering unit senses the amount of material fed into the storage tank and sends a signal to the control unit after sensing the amount of material fed into the second valve as the required amount. After receiving the signal, the control unit controls the first valve to close. Step 3: Control the vacuum equipment to evacuate the storage tank so that the vacuum state inside the storage tank is consistent with that inside the hollow mixing tank; Step 4: When the predetermined appropriate time is reached, the timing unit controls the second valve body to rotate, causing the material to fall and cleaning the inner wall of the storage tank.

[0013] The beneficial effects of this invention are as follows: 1. This adaptive flow control vacuum emulsifier controls and measures the material feeding process before and after feeding through a flow controller, so as to realize timely and quantitative material feeding. Precise flow control maintains the accuracy of material ratio, ensures the consistency between product batches, and realizes coordinated control of the flow of the whole line, thereby improving production efficiency.

[0014] 2. This adaptive flow control vacuum emulsifier, by setting up a dual valve body and a storage tank, ensures that the emulsifier is always in a vacuum state by opening the dual valve bodies separately, reducing the possibility of air being mixed into the emulsifier during the feeding process. At the same time, since the emulsifier is not in contact with the external environment, the material inside the emulsifier will not splash out from the feed port, thereby reducing the possibility of personnel being burned during the feeding process.

[0015] 3. This adaptive flow control vacuum emulsifier, by setting the first valve body as a first cover for sealing and a movable second cover respectively, allows the first valve body to seal the feed inlet while pushing the material more completely into the emulsifier for mixing. This ensures the reliability of the material ratio to a certain extent and reduces the possibility of material adhesion causing the first and second valve bodies to fail, thus ensuring the normal operation of the emulsifier. At the same time, by blocking the vent through the second cover, the material can be blocked to a certain extent during the vacuuming process of the storage tank, preventing the material from entering the vacuuming device.

[0016] Other advantages, objectives, and features of the invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination, or may be learned from practice of the invention. The objectives and other advantages of the invention can be realized and obtained through the following description. Attached Figure Description

[0019] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structure, features and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0020] Please see Figure 1-3 This invention provides an adaptive flow control vacuum emulsifier technical solution: An adaptive flow control vacuum emulsifier includes a vacuum mixing tank 1, a feed inlet 11, a storage tank 2, a feed valve 3, an automatic feeding device 4, and a controller. The vacuum mixing tank 1 is used to mix materials. The feed inlet 11 is located above the vacuum mixing tank 1. The storage tank 2 is open at both ends and connected to the feed inlet 11, used to store the materials to be added. The end of the storage tank 2 away from the feed inlet 11 is connected to the automatic feeding device 4 for automatic feeding. The feed valve 3 is connected to the storage tank 2 and used to close the storage tank 2. The controller and... The feed valve 3 is electrically connected, and the controller is used to control the opening and closing of the feed valve 3. The feed valve 3 includes a first valve body 31 and a second valve body 32. The first valve body 31 is located at the end of the storage tank 2 away from the vacuum mixing tank 1, and the second valve body 32 is located at the end of the storage tank 2 close to the vacuum mixing tank 1. The space between the first valve body 31 and the second valve body 32 is used for storing materials. The feed valve 32 also includes a vacuuming device 5. The side wall of the storage tank 2 away from the vacuum mixing tank 1 is provided with a vent 51, and the vent 51 is connected to the vacuuming device 5. The vacuuming device 5 is electrically connected to the controller, and the controller is used to control the vacuuming device 5 to vacuum the storage tank 2. The controller includes a process setting unit, a timing unit, and a metering unit. The process setting unit is used to input and set relevant processes, split the task data of the timing unit and the metering unit, and send the data to the timing unit and the metering unit respectively. The timing unit receives data from the process setting unit, performs timing under the corresponding time program, and sends the timing result to the control unit. The metering unit is used to receive data from the process setting unit, sense the amount of material entering the storage tank 2, and send the sensing result to the control unit. The control unit is used to control the opening and closing of the first valve body 31 or the second valve body 32 after receiving the signal from the timing unit or the metering unit, and at the same time, after the material is fed into the storage tank 2, it controls the vacuum device 5 to vacuum the storage tank 2.

[0021] When using the adaptive flow control vacuum emulsifier of the present invention to stir the vacuum mixing tank 1, the relevant process is first set by inputting the process setting unit. Then, the process setting unit splits the task data of the timing unit and the metering unit and sends the data to the timing unit and the metering unit respectively. The equipment is started. At this time, the first valve body 31 and the second valve body 32 are in a closed state. The timing unit starts timing. The metering unit sends a signal to the control unit to make the control unit control the first valve body 31 to open and start feeding the storage tank 2. By connecting the corresponding automatic feeding device 4 to one end near the first valve body 31, the manual operation is reduced, making the present invention more automated. At the same time, since the second valve body 32 is still in a closed state, the vacuum mixing tank 1 will not be unable to maintain a vacuum state due to the opening of the first valve body 31. To a certain extent, this ensures the continued operation of the vacuum mixing tank 1 during the feeding process. When the metering unit senses that the feeding quantity is the required amount, it sends a signal to the control unit. The control unit controls the first valve body 31 to close and seal the storage tank 2 to stop feeding. In this way, the stirring process in the vacuum mixing tank 1 is not interfered with while feeding is automated, ensuring the normal operation of the equipment.

[0022] After feeding the storage tank 2, the vacuum device 5 is controlled by the control unit to evacuate the storage tank 2, so that the vacuum level inside the storage tank 2 is consistent with that inside the vacuum mixing tank 1. Then, when the timing unit reaches the predetermined time point, it sends a signal to the control unit, causing the control unit to control the second valve 32 to open. Since the vacuum level inside the storage tank 2 is consistent with that inside the vacuum mixing tank 1 at this time, the material entering the storage tank 2 will not disrupt the vacuum level inside the vacuum mixing tank 1. Thus, the present invention can complete the feeding task into the vacuum mixing tank 1 at timed and quantitative times without manual operation while maintaining the vacuum environment inside the vacuum mixing tank 1, reducing the workload of the staff and ensuring the quality of the products produced by the present invention to a certain extent.

[0023] In this embodiment: the storage tank 2 is provided with a first rotating rod 33 and a second rotating rod 34 at the openings at both ends. The first rotating rod 33 and the second rotating rod 34 can be rotatably connected to the storage tank 2 and electrically connected to the control unit. The control unit is used to control the rotation of the rotating rod. The first valve body 31 and the second valve body 32 are connected to the first rotating rod 33 and the second rotating rod 34 in a one-to-one correspondence. It also includes a holding rod 35, a first cam 36, and a second cam 37. The side wall of the storage tank 2 is hollow, forming a receiving cavity 38. One end of the first rotating rod 33 and the second rotating rod 34 both extend into the receiving cavity 38 along the length direction. The holding rod 35 is slidably disposed in the receiving cavity 38 along the length direction of the storage tank 2. One end of the first rotating rod 33 extending into the receiving cavity 38 is connected to the first cam 36, and one end of the second rotating rod 34 extending into the receiving cavity 38 is connected to the second cam 37. The first cam 36 and the second cam 37... The protrusions are all arranged along the length direction of the abutment rod 35 and perpendicular to the first valve body 31 and the second valve body 32. The first cam 36 and the second cam 37 are parallel to one side of the length direction of the first rotating rod 33 and the second rotating rod 34 and contact the side wall of the receiving cavity 38. The abutment rod 35 is located on the side opposite to the side of the first cam 36 and the second cam 37 that abuts the side wall of the receiving cavity 38, and the sides of both ends of the abutment rod 35 are respectively in contact with the side opposite to the side of the first cam 36 and the second cam 37 that abuts the side wall of the receiving cavity 38.

[0024] Since the first rotating rod 33 is connected to the first cam 36 at one end extending into the receiving cavity 38, rotating the first rotating rod 33 can drive the first cam 36 to rotate. Similarly, the second rotating rod 34 is connected to the second cam 37 at one end extending into the receiving cavity 38, and rotating the second rotating rod 34 can drive the second cam 37 to rotate. Because the protrusions of both the first cam 36 and the second cam 37 are arranged along the length direction of the abutment rod 35, one side of the first cam 36 and the second cam 37 parallel to the length direction of the first rotating rod 33 and the second rotating rod 34 contacts the sidewall of the receiving cavity 38. The protrusions of the first cam 36 and the second cam 37 can only face the first cam 36 and the second cam 37. The second cam 37 rotates against one side of the sidewall of the receiving cavity 38. Since the first cam 36 and the second cam 37 are perpendicular to the first valve body 31 and the second valve body 32, when the protrusions of the first cam 36 and the second cam 37 are arranged along the length direction of the holding rod 35, the first valve body 31 and the second valve body 32 are in a closed state. When the protrusions of the first cam 36 and the second cam 37 rotate toward the sidewall of the receiving cavity 38 against which the first cam 36 and the second cam 37 are located, the first valve body 31 and the second valve body 32 will be opened. In this way, the opening and closing of the first valve body 31 and the second valve body 32 can be controlled.

[0025] Since the abutment rod 35 is located on the side opposite to the side wall of the receiving cavity 38 of the first cam 36 and the second cam 37, and the sides of both ends of the abutment rod 35 are in contact with the side opposite to the side wall of the receiving cavity 38 of the first cam 36 and the second cam 37, when the first rotating rod 33 rotates, it drives the first cam 36 to rotate, causing the first valve body 31 to open. At this time, the protrusion of the first cam 36 rotates towards the abutment rod 35 to abut against the abutment rod 35, thereby abutting the abutment rod 35 against the rotation of the second cam 37, preventing the second cam 37 from rotating and keeping the protrusion of the second cam 37 parallel to the abutment rod 35, thus keeping the second valve body 32 closed. At this time, the storage tank 2 can be fed. When the storage tank 2 is fed, the first rotating rod 33 rotates back to its original position, driving the first cam 36 to rotate to the position opposite to the abutment rod. When the first valve body 31 is closed due to the parallel state of valve 35, a vacuum operation can be performed inside the storage tank 2. When the vacuuming of the storage tank 2 is completed and the material needs to be put into the vacuum mixing tank 1, the second rotating rod 34 rotates, causing the second cam 37 to rotate and opening the second valve body 32. At this time, the protrusion of the second cam 37 rotates towards the abutment rod 35 to abut the abutment rod 35, thereby abutting the rotation of the first cam 36 by the abutment rod 35, preventing the first cam 36 from rotating and keeping the protrusion of the first cam 36 parallel to the abutment rod 35, thus keeping the first valve body 31 closed. In this way, when either the first valve body 31 or the second valve body 32 is opened, the other valve body will be closed, which to a certain extent ensures the vacuum state inside the vacuum mixing tank 1 during the feeding process, thereby ensuring the mixing and emulsification quality of the present invention.

[0026] In this embodiment: the first valve body 31 includes a first cover 311 and a second cover 312, which can be closed to form a hollow cavity. Both the first cover 311 and the second cover 312 abut against the side wall of the storage tank 2. A connecting rod 313 and a telescopic rod 314 are provided between the first cover 311 and the second cover 312. The two ends of the connecting rod 313 are respectively connected to the first cover 311 and the rotating rod. The base of the telescopic rod 314 is connected to the rotating rod, and the output end is connected to the second cover 312. The surface of the second cover 312 is provided with a plurality of air holes 3121, which communicate with the interior of the storage tank 2 and the cavity. The control unit includes an execution unit, a cleaning unit, and a vacuuming unit. The execution unit is used to control the opening and closing of the first valve body 31 or the second valve body 32 after receiving a signal from the timing unit or the metering unit. The vacuuming unit is electrically connected to the telescopic rod 314 and the vacuuming device 5. The vacuuming unit is used to control the telescopic rod 314 to extend to the lower edge of the vent 51 and control the vacuuming device 5 to perform vacuuming after the material tank 2 is closed after feeding. The cleaning unit is electrically connected to the telescopic rod 314. The cleaning unit is used to push the telescopic rod 314 to continue to extend when the second valve body 32 is opened.

[0027] Since the base of the telescopic rod 314 is connected to the rotating rod and the output end is connected to the second cover 312, the telescopic rod 314 can extend and retract to drive the second cover 312 to move up and down. When the storage tank 2 is being fed, the telescopic rod 314 retracts to its shortest length so that the first cover 311 and the second cover 312 can rotate together, thereby putting the first valve body 31 in the open state. When the storage tank 2 is finished being fed, the first valve body 31 closes, the vacuum unit controls the telescopic rod 314 to extend to the lower edge of the vent 51, and then controls the vacuum device 5 to perform vacuuming. Since the surface of the second cover 312 is provided with multiple air holes 3121, the air holes 3121 connect the inside of the storage tank 2 and the cavity. When the vacuum device 5 performs vacuuming in the storage tank 2, the material will be blocked by the second cover 312, thereby reducing the possibility of the material being sucked into the vacuum device 5, thus ensuring the amount of material in the storage tank 2.

[0028] Since both the first cover 311 and the second cover 312 abut against the side wall of the storage tank 2, the cleaning unit is used to push the telescopic rod 314 to continue to extend when the second valve 32 is opened. When the second valve 32 is opened for feeding, the first cover 311 always abuts against the wall of the storage tank 2 to seal the storage tank 2, thereby reducing the possibility of outside air entering and disrupting the vacuum state inside the vacuum mixer. The extension of the telescopic rod 314 allows the second cover 312 to push the material into the vacuum mixing tank 1, and at the same time cleans the inner wall of the storage tank 2, reducing the possibility of material residue on the side wall of the storage tank, thereby ensuring the accuracy of feeding the storage tank 2 in the next use.

[0029] In this embodiment: the output end of the telescopic rod 314 is connected to a first scraper 315 and a driving unit. The first scraper 315 is rotatably connected to the second cover plate and abuts against the side of the second cover plate facing the vacuum mixing tank 1. The driving unit is used to drive the first scraper 315 to rotate.

[0030] Since the second cover plate is held against the side facing the vacuum mixing tank 1, the driving unit is used to drive the first scraper 315 to rotate. The driving unit drives the first scraper 315 to rotate so as to clean the surface of the second cover plate, thereby reducing the possibility of material adhering to the surface of the second cover plate and clogging the air port.

[0031] 5. In this embodiment: the driving part includes a rotating part 316 and a fan blade 317. The rotating part 316 passes through the two sides of the second cover plate facing and away from the vacuum mixing tank 1 and is rotatably connected to the second cover plate. The fan blade 317 is connected to the end of the rotating part 316 away from the vacuum mixing tank 1. The first scraper 315 is connected to the end of the rotating part 316 close to the vacuum mixing tank 1.

[0032] When the vacuuming device 5 starts vacuuming, the air in the storage tank 2 is drawn away by the vacuuming device 5 to form an airflow. This airflow flows from the side of the second cover plate toward the vacuum mixing tank 1 to the side of the second cover plate away from the vacuum mixing tank 1 and then to the vacuuming device 5. The resulting airflow can drive the fan blade 317 to rotate, thereby driving the first scraper 315 to rotate, so that the first scraper 315 cleans the second cover plate. With this structure, the airflow of the vacuuming device drives the first scraper 315 to rotate, thereby reducing the use of the power device. As the storage tank 2 gradually enters a vacuum state, the vacuuming device 5 stops operating. At this time, the first scraper 315 can also stop rotating, so that the first scraper 315 can be stopped without external force, which saves energy to a certain extent and avoids over-design.

[0033] In this embodiment: the rotating part 316 has a bidirectional thread 3161 on the side away from the vacuum mixing tank 1 in the middle, and also includes a sleeve 3162, a slider, a support rod 3163 and a vent needle 3164. The sleeve 3162 is sleeved on the outer peripheral surface of the rotating part 316 and can be slidably connected to the second cover 312 along the length direction of the rotating part 316. The slider is connected inside the sleeve 3162 and can be slidably connected to the bidirectional thread 3161. There are multiple support rods 3163, which are arranged radially with the length direction of the rotating part 316 as the center line and connected to the outer peripheral surface of the sleeve 3162. The vent needles 3164 are all connected to the multiple support rods 3163, and each vent needle 3164 corresponds to multiple air ports.

[0034] 7. In this embodiment: The inner wall of the storage tank 2 is recessed inward to form a groove 21. There are two grooves 21, and the two grooves 21 face each other. It also includes a side wall cleaning mechanism. There are two sets of side wall cleaning mechanisms, and the two sets of side wall cleaning mechanisms correspond one to one of the two grooves 21. The side wall cleaning mechanism is used to clean the inner wall of the storage tank 2 corresponding to the two sides of the second valve body 32 when the second valve body 32 is flipped. The side wall cleaning mechanism includes a sliding rod 23, a connecting block 24, an elastic element 25, and a second scraper 22. The second scraper 22 abuts against the inner wall of the storage tank 2. The sliding rod 23 is arranged along the length direction of the storage tank 2, and one end of the sliding rod 23 facing the vacuum mixing tank 1 is connected to the second scraper 22. One end of the connecting block 24 is slidably connected to the groove 21, and the other end is connected to the second scraper 22. The elastic element 25 is disposed in the groove 21, and the two ends of the elastic element 25 are respectively connected to the side wall of the groove 21 near the vacuum mixing tank 1 and the second scraper 22.

[0035] When the material in storage tank 2 needs to be transferred to vacuum mixing tank 1, the second valve body 32 opens, and the material in storage tank 2 falls. At this time, the cleaning unit controls the extension rod 314 to extend, thereby driving the second cover 312 to move towards vacuum mixing tank 1. Since the side wall of the second cover 312 abuts against the inner wall of storage tank 2, the edge of the second cover 312 can clean storage tank 2. Since the sliding rod 23 is set along the length of storage tank 2, one end of the connecting block 24 is slidably connected to the groove 21, and the other end is connected to the second scraper 22. When the second cover 312 moves a certain distance, it can abut against the sliding rod 23, thereby causing the sliding rod 23 to move towards vacuum mixing tank 1. Since the end of the sliding rod 23 facing vacuum mixing tank 1 is connected to the second scraper 22, the sliding rod 23... When moving towards the vacuum mixing tank 1, the second scraper 22 can be moved towards the vacuum mixing tank 1, so that the second scraper 22 can clean the part of the storage tank 2 side wall that cannot be cleaned due to the second valve body 32 being held against the second cover plate by the second valve body 32 being opened, thus ensuring the integrity of the cleaning of the inner wall of the storage tank 2 to a certain extent; since the elastic element 25 is provided in the groove 21 and the two ends of the elastic element 25 are respectively connected to the side wall of the groove 21 near the vacuum mixing tank 1 and the second scraper 22, when the second cover 312 has finished cleaning the side wall of the storage tank 2, when the cleaning unit controls the telescopic rod 314 to shorten, the second cover 312 resets, that is, it removes the resistance to the sliding rod 23. At this time, the elastic element 25 drives the second scraper 22 to reset, so that the second scraper 22 can clean the side wall of the storage tank 2 again.

[0036] A feeding method for an adaptive flow control vacuum emulsifier, using the aforementioned adaptive flow control vacuum emulsifier, includes the following steps: Step 1: Input the relevant process settings into the process setting unit, and split the task data of the timing unit and the metering unit through the process setting unit and send the data to the timing unit and the metering unit respectively; Step 2: When the equipment is started, the timing unit starts timing. The metering unit sends a signal to the control unit to make the control unit control the first valve body 31 to open the feed. The metering unit senses the amount of feed in the storage tank 2 and sends a signal to the control unit after sensing the amount of feed in the second valve body 32 as the required amount. After receiving the signal, the control unit controls the first valve body 31 to close. Step 3: Control the vacuum equipment to evacuate the storage tank 2 so that the vacuum state inside the storage tank 2 is consistent with that inside the hollow mixing tank; Step 4: When the predetermined appropriate time is reached, the timing unit controls the second valve body 32 to rotate, causing the material to fall and clean the inner wall of the storage tank 2.

[0037] When feeding material using the adaptive flow control vacuum emulsifier of this invention, the relevant process is first set by inputting the process setting unit. Then, the process setting unit splits the task data of the timing unit and the metering unit and sends the data to the timing unit and the metering unit respectively. The equipment is then started, the timing unit begins timing, and the metering unit sends a signal to the control unit to open the first valve 31 to begin feeding the storage tank 2. When the metering unit senses that the feeding quantity is the required amount, it sends a signal to the control unit, which then closes the first valve 31 to seal the storage tank 2. After feeding the storage tank 2 is complete, the flow is... The vacuum device 5, controlled by the control unit, evacuates the storage tank 2 to make the vacuum level inside the storage tank 2 consistent with that inside the vacuum mixing tank 1. Then, when the timing unit reaches the predetermined time point, it sends a signal to the control unit, causing the control unit to open the second valve body 32 to allow the material to fall. At the same time, the cleaning unit controls the extension rod 314 to extend and drive the second cover 312 to clean the inner wall of the storage tank 2. After feeding is completed, the second valve body 32 closes. In this way, the adaptive flow control vacuum emulsifier of the present invention will not disrupt the vacuum environment inside the vacuum mixing tank 1 during feeding, thus ensuring the mixing quality of the vacuum emulsifier.
