Description

Technical Field

[0001] This invention relates to the field of surfactant quantitative detection technology, specifically to a surfactant quantitative detection component and detection method for disinfected tableware. Background Technology

[0002] Surfactants are a type of detergent. Surfactants can be natural, such as phospholipids, choline, and proteins, but many are synthetic, such as sodium octadecyl sulfate and sodium stearate. Surfactants have a very wide range of applications, providing various functions including foaming, surface modification, cleaning, emulsification, rheology, and environmental and health protection. If excessive surfactant residue remains on tableware after disinfection, it can affect subsequent use; therefore, it is necessary to test for surfactant residue on disinfected tableware.

[0003] CN216594789U discloses a multi-channel device for quantitative detection of anionic surfactants in sterilized tableware. This device includes a main body with multiple sample bottles inside. Each sample bottle has a first reaction ring at its bottom, a first phase separation device at its bottom, and a second reaction ring at its bottom. However, this device suffers from low mixing efficiency and poor mixing effect.

[0004] However, the above-mentioned device still has the following problems during implementation:

[0005] Existing methods for quantitative detection of surfactants in disinfected tableware typically involve immersing the disinfected tableware in clean water for sampling, then transferring the water to a beaker for methylene blue spectrophotometry. This involves adding a standard sodium alkyl sulfate solution to the water, followed by adding phenolphthalein as an indicator, adding hydroxide solution to turn the liquid pink, then adding sulfuric acid solution to remove the pink color, and finally adding toluene solution and chloroform, among other chemicals, to obtain the test sample. During this process, each addition of a chemical requires thorough stirring of the liquid in the beaker. However, manual stirring is ineffective and time-consuming, significantly increasing the testing time.

[0006] In actual mixing of liquids inside a beaker, if the amount of liquid inside the beaker changes, existing technologies lack the function to adjust the height of the mixing swing of the liquid inside the beaker, thereby reducing the mixing effect of the liquid.

[0007] Meanwhile, when raw materials or impurities adhere to the beaker and its internal structure, the above-mentioned technologies lack the ability to scrape off the raw materials adhering to the internal structure of the beaker, thereby reducing the mixing and cleaning effect of the liquid inside the beaker and resulting in low adaptive adjustment efficiency.

[0008] In existing technologies, the reflux rate and flow rate of the liquid at the bottom of the beaker are constant, which can easily reduce the mixing effect of the liquid. Furthermore, when the degree of mixing of the liquid inside the beaker does not meet the required mixing concentration, the aforementioned devices lack the function of adjusting the liquid mixing, thus failing to meet actual detection needs. Summary of the Invention

[0009] The purpose of this invention is to provide a quantitative detection component and method for surfactants in disinfected tableware, so as to solve the problems mentioned in the background art.

[0023] A method for quantitative detection of surfactants in disinfected tableware, comprising the following steps, using the aforementioned surfactant quantitative detection component for disinfected tableware.

[0024] S1: First, take a sample of the sterilized tableware by placing it in clean water. Then, take out the clean water and put it into a beaker. Next, add the chemical raw materials to the clean water in sequence.

[0025] S2: After each addition of chemical raw materials, the stirring mechanism is activated to stir the liquid in the beaker so that the liquid and chemical raw materials are mixed;

[0026] S3: While the stirring mechanism is stirring, the auxiliary mechanism will swing left and right inside the beaker;

[0027] S4: While the auxiliary mechanism is swinging, the jetting mechanism will collect the liquid and then spray it from bottom to top. Driven by the liquid flow, the liquid inside the beaker will rise to the stirring mechanism, further improving the stirring effect.

[0028] S5: When the swing plate moves downward, it will cause the elastic extrusion block and the splicing block to be elastically extruded, and the one-way drainage pipe will elastically deform and perform pulse spraying.

[0029] S6: When the concentration values ​​detected by multiple concentration sensors are less than the preset concentration value, the controller controls the electric telescopic rod to extend, the minimum distance between the push plate and the side wall of the beaker decreases, and the mixing and stirring effect of the liquid inside the beaker is enhanced.

[0030] S7: After mixing all the raw materials with the liquid, open the detection head and test the sample liquid.

[0031] Compared with the prior art, the beneficial effects of the present invention are:

[0032] 1. This invention, by setting up a stirring mechanism, can stir the liquid after adding chemical raw materials to the beaker. This solves the problem that manual stirring is ineffective and requires a lot of time to stir in order to fully dissolve the chemical raw materials in the beaker, thus significantly increasing the detection time.

[0033] 2. By setting up an auxiliary mechanism, the present invention can, while the rotating block in the stirring mechanism is rotating, work in conjunction with the auxiliary mechanism to reciprocate horizontally agitate the liquid in the beaker, thereby further improving the mixing effect and solving the problem that if the liquid in the beaker is fused with the chemical raw materials by centrifugal force alone during the stirring process, the actual fusion speed will not be much improved.

[0034] 3. By setting up a first connecting block, a swing arm, a second connecting block, and a swing plate, the present invention enables the first connecting block to move along with the push plate during the reciprocating movement of the push plate. At the same time, the first connecting block pulls the swing arm to move, and the swing arm will adaptively rotate around the rotating axis. Simultaneously, it pulls the second connecting block and the swing plate to move up and down reciprocally, so that the liquid and chemical raw materials also have the function of up and down stirring when mixed, thereby improving the mixing effect.

[0035] 4. By incorporating a jetting mechanism, this invention enables liquid to be collected inside the collection tank when the push plate moves closer to the return spring. Subsequently, when the return spring pushes the push plate away from the spring, the push plate drives the extrusion rod, extrusion plate, and piston to move, compressing the mixed liquid inside the collection tank. When the pressure reaches the limit of the one-way pressure valve on the one-way drain pipe, the mixed liquid is ejected upwards from the one-way drain pipe, driving the liquid as a whole towards the stirring mechanism, thereby improving the stirring effect. This solves the problem that the optimal stirring position in the beaker is still at the stirring mechanism, while some liquid at the bottom cannot reach the stirring mechanism for stirring and cannot be quickly and fully mixed by simply swaying left and right with the auxiliary mechanism.

[0036] 5. By setting up a lifting mechanism, the present invention can drive the rotating blade and rotating block to rotate during the process of liquid spraying from the one-way discharge pipe, under the action of the mixed liquid floating upward, thereby further increasing the upward force of the liquid. At the same time, the rotation of the rotating blade can also improve the stirring effect.

[0037] 6. By setting a sealing mechanism, the present invention can seal the beaker after the raw materials are added to prevent the liquid from splashing out of the beaker during the stirring process.

[0038] 7. This invention, by incorporating an electric telescopic rod and an elastic squeezing block, offers a simple and easily adjustable device. It enables one-time mixing and stirring of the liquid inside the beaker, achieving horizontal, vertical, and circumferential stirring for more uniform and thorough mixing. Simultaneously, it allows for upward backflow of liquid from the bottom of the beaker, preventing sedimentation. Furthermore, pulsed backflow during actual mixing enhances cleanliness and improves mixing efficiency. The extension length of the electric telescopic rod can be adjusted according to the liquid level and mixing effect at various heights, thereby regulating mixing efficiency, resulting in greater adaptability, higher stability, and better mixing performance.

[0050] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0051] Example 1:

[0052] Please see Figure 1-9 This invention provides a technical solution: a quantitative detection component for surfactants in disinfected tableware, comprising a base 1, a U-shaped frame 2, and a beaker 3. A controller is located on the top of the base 1, electrically controlling various electro-hydraulic components. Multiple sets of liquid concentration sensors are installed at the same height inside the beaker 3 to detect the concentration of the mixed liquid inside. These sensors not only detect the height of the liquid inside the beaker 3 but also the degree of mixing, thus ensuring the accuracy and stability of the liquid mixing. The U-shaped frame 2 is fixedly installed on the top of the base 1, and the beaker 3 is fixedly installed inside the U-shaped frame 2. The U-shaped frame 2 primarily fixes the position of the beaker 3. A drain pipe 37 is fixedly connected to the bottom of the beaker 3, used to drain the mixed liquid inside the beaker 3. The bottom of the drain pipe 37 extends to the bottom of the base 1, and a water valve 38 is provided on the surface of the drain pipe 37. Opening the water valve 38 allows the mixed liquid inside the drain pipe 37 to be discharged.

[0053] The top of the base 1 is equipped with a stirring mechanism. When chemical raw materials are added to the beaker 3, the stirring mechanism will stir them to mix the water and chemical raw materials, thereby reducing the detection time.

[0054] An auxiliary mechanism is provided on the outer surface of the stirring mechanism. The auxiliary mechanism is fixedly installed on the stirring mechanism. When the stirring mechanism is stirring, the auxiliary mechanism will swing left and right inside the beaker 3 to improve the stirring effect and thus save the detection time.

[0055] Both sides of the beaker 3 are equipped with a jetting mechanism, which is fixedly mounted on the U-shaped frame 2. When the auxiliary mechanism swings, the jetting mechanism collects the liquid and then sprays it from bottom to top. Driven by the liquid flow, the liquid inside the beaker 3 rises to the stirring mechanism, further improving the stirring effect.

[0056] The stirring mechanism includes a motor 4 fixedly installed on the top of the U-shaped frame 2. The output end of the motor 4 extends into the interior of the U-shaped frame 2 and is equipped with a rotating rod 5. The bottom of the rotating rod 5 extends into the interior of the beaker 3 and is equipped with a rotating block 6. The outer surface of the rotating block 6 is equipped with four fan blades 7. By setting up the stirring mechanism, the motor 4 can be started after chemical raw materials are added to the beaker 3. The motor 4 drives the rotating rod 5 to rotate, and the rotating rod 5 drives the rotating block 6 and fan blades 7 to stir the liquid, thereby generating centrifugal force, so that the chemical raw materials can be quickly mixed with the liquid, reducing the detection time. This solution effectively solves the problem that manual stirring is ineffective and requires a lot of time to stir in order to fully dissolve the chemical raw materials in the beaker 3, thus greatly increasing the detection time.

[0057] A through hole 28 is provided on one side of the fan blade 7. There are multiple through holes 28. By setting through holes 28, the mixing effect between the liquid and chemical raw materials can be improved when the fan blade 7 rotates and mixes them, so that they can be mixed together faster.

[0058] The stirring mechanism can reduce the time for chemical raw materials to fuse with the liquid in beaker 3 by stirring, thereby reducing the detection time. However, if the liquid in beaker 3 is fused with chemical raw materials by centrifugal force alone during stirring, the actual fusion speed improvement is not significant. Therefore, the auxiliary mechanism in this application includes a missing gear 8 fixedly installed at the bottom of the rotating block 6, with a return spring 9 at the bottom of the missing gear 8. The auxiliary mechanism also includes a push plate 10, which is slidably connected to the inside of beaker 3. Both sides of the return spring 9 are fixedly connected to the opposite side of the push plate 10. Each opposite side of the push plate 10 is provided with an electric telescopic rod 39, and the output end of the electric telescopic rod 39 is provided with a toothed plate 11 that meshes with the missing gear 8. By setting up the auxiliary mechanism, during rotation... As block 6 rotates, it drives the missing gear 8 to rotate as well. When the toothed end of the missing gear 8 contacts and meshes with the toothed plate 11, the missing gear 8 will drive the toothed plate 11, the push plate 10, and the sliding block 29 to move along the trajectory of the sliding groove 30 towards the side closer to the inner wall of the beaker 3. At the same time, the return spring 9 is stretched. When the missing gear 8 rotates to the point where the toothed end no longer contacts and meshes with the toothed plate 11, under the influence of the elastic force of the return spring 9, the push plate 10 will move along the trajectory of the sliding groove 30 away from the inner wall of the beaker 3. This reciprocating motion stirs the liquid in the beaker 3 by moving horizontally back and forth, further improving the mixing effect. This solution solves the problem that the actual mixing speed is small when the liquid in the beaker 3 is fused with the chemical raw materials by centrifugal force alone during the stirring process.

[0059] A swing plate 35 is slidably connected to the inner walls of both sides of the beaker 3. A first connecting block 32 is provided on one side of the push plate 10. A swing arm 33 is movably connected to one side of the first connecting block 32 through a rotating shaft. A second connecting block 34 is movably connected to one end of the swing arm 33 through a rotating shaft. The top of the second connecting block 34 is hinged to the bottom of the swing plate 35. By setting the first connecting block 32, the swing arm 33, the second connecting block 34 and the swing plate 35, the first connecting block 32 moves with the push plate 10 during the reciprocating motion of the push plate 10. At the same time, the first connecting block 32 pulls the swing arm 33 to move. The swing arm 33 will adapt to rotate around the rotating shaft and pull the second connecting block 34 and the swing plate 35 to move up and down. This allows the liquid and chemical raw materials to have an up-and-down stirring function when mixed, improving the mixing effect.

[0060] The side wall of beaker 3 is provided with a T-shaped groove, and a T-shaped block is provided inside the T-shaped groove. The side wall of the T-shaped block is fixedly connected to the side wall of the swing plate 35. The structure of the T-shaped groove and the T-shaped block restricts its movement trajectory to only up and down. This method is well known to those skilled in the art, so it will not be described in detail.

[0061] The bottom of the push plate 10 is provided with a sliding block 29, and the inner wall of the beaker 3 is provided with a sliding groove 30 that meshes with the sliding block 29. By setting the sliding block 29 and the sliding groove 30, the movement trajectory of the push plate 10 and other structures can be restricted, so that they can only move horizontally back and forth, thus playing a guiding role.

[0062] The auxiliary and stirring mechanisms can only improve the stirring effect of the liquid and chemical raw materials in beaker 3 and reduce the stirring time. However, the best stirring effect in beaker 3 is still at the stirring mechanism. Some liquids at the bottom cannot reach the stirring mechanism for stirring. The auxiliary mechanism can only shake the liquids left and right, which cannot quickly and fully mix them.

[0063] The jetting mechanism in this application includes a collection tank 12 fixedly disposed on both sides of the beaker 3. A piston 13 is disposed inside the collection tank 12. A squeezing plate 14 is disposed on one side of the piston 13. A squeezing rod 15 is disposed on one side of the squeezing plate 14. One end of the squeezing rod 15 penetrates into the interior of the beaker 3 and is fixedly connected to one side of the push plate 10. When the push plate 10 moves laterally, the push plate 10 drives the piston 13 to move laterally inside the collection tank 12 through the squeezing rod 15 and the squeezing plate 14. The hydraulic pressure inside the collection tank 12 changes accordingly, thereby realizing the reflux and mixing of the mixed liquid at the bottom of the beaker 3.

[0064] The liquid collection tank 12 is fixedly connected to a one-way inlet pipe 16 via a one-way valve on the side near the beaker 3. The top of the liquid collection tank 12 is fixedly connected to two one-way outlet pipes 17 via a one-way pressure valve. One end of each outlet pipe 17 extends into the interior of the beaker 3. A lifting mechanism is provided on the surface of each outlet pipe 17. This lifting mechanism assists the jetting mechanism in propelling the liquid upwards and also serves as an auxiliary stirring mechanism. By providing the jetting mechanism, when the push plate 10 moves closer to the inner wall of the beaker 3, the push plate 10 drives the extrusion rod 15, the extrusion plate 14, and the piston 13 to move. When the liquid collection tank 12 is activated, the mixed liquid inside the beaker 3 enters the liquid collection tank 12 through the one-way inlet pipe 16 under the action of hydraulic pressure. Then, when the return spring 9 drives the push plate 10 to move closer to each other, the push plate 10 drives the extrusion rod 15, extrusion plate 14 and piston 13 to move, so as to compress the mixed liquid inside the liquid collection tank 12. When the liquid pressure inside the liquid collection tank 12 reaches the limit of the one-way pressure valve on the one-way drain pipe 17, the mixed liquid will be sprayed upward from the one-way drain pipe 17 and drive the liquid as a whole to rush towards the stirring mechanism, thereby improving the stirring effect.

[0065] This design effectively solves the problem that the best stirring position in beaker 3 is still at the stirring mechanism, while some liquid at the bottom cannot reach the stirring mechanism for stirring. The liquid cannot be quickly and fully mixed by simply swinging left and right with the auxiliary mechanism. In this application, the one-way valve on the one-way liquid inlet pipe 16 is a valve that can only allow liquid to enter, while the one-way pressure valve on the one-way liquid outlet pipe 17 is a valve that can only allow liquid to exit.

[0066] The jetting mechanism can only push the liquid upward to the stirring mechanism. However, if the liquid mixture alone is used to push the liquid to the stirring mechanism, the force of the surge is still insufficient. In this application, the lifting mechanism includes a support rod 18 fixedly installed on the one-way drain pipe 17. The top of the support rod 18 is rotatably connected to a rotating block 19 via a rotating shaft. The surface of the rotating block 19 is provided with a rotating blade 20. By setting up the lifting mechanism, the rotating blade 20 and the rotating block 19 can be driven to rotate under the action of the floating of the liquid mixture during the liquid jetting process of the one-way drain pipe 17, thereby further increasing the force of the liquid surge. At the same time, the rotation of the rotating blade 20 can also improve the stirring effect.

[0067] The stirring mechanism, auxiliary mechanism, jetting mechanism and lifting mechanism can improve the mixing effect and reduce the stirring time. However, during the stirring process, the liquid may overflow from the beaker 3. In this application, the top of the beaker 3 is provided with a sealing mechanism to prevent the liquid from splashing out during the mixing process.

[0068] The sealing mechanism includes a sealing plate 21 movably mounted on the top of the beaker 3. One side of the sealing plate 21 is rotatably connected to one side of the beaker 3 via a hinge. A silicone pad 22 is provided at the bottom of the sealing plate 21. A housing 23 is provided on one side of the beaker 3. A movable block 24 is provided inside the housing 23. L-shaped blocks 25 are provided on both sides of the movable block 24. A positioning rod 26 is provided on one side of the L-shaped block 25. A positioning hole 27 that engages with the positioning rod 26 is provided on one side of the sealing plate 21. A pulling rod 36 is provided on one side of the movable block 24. One end of the pulling rod 36 extends to the outside of the housing 23. By setting up the sealing mechanism, after the raw material is added, pulling the pulling rod 36 will drive the movable block 24, the L-shaped block 25, and the positioning rod 26. Move the sealing plate 21 to a position that does not affect its rotation. Rotate the sealing plate 21 and the sealing gasket around the hinge to the top of the beaker 3. Then release the pull rod 36. The elastic force generated by the compression spring 31 pushes the movable block 24, the L-shaped block 25 and the positioning rod 26 to move, so that the positioning rod 26 enters the positioning hole 27, thereby restricting the position of the sealing plate 21 and preventing liquid from overflowing from the beaker 3 during stirring. A compression spring 31 is provided on one side of the movable block 24. One end of the compression spring 31 is fixedly connected to the inner wall of the housing 23. By setting the compression spring 31, the movable block 24, the L-shaped block 25 and the positioning rod 26 can be reset, so that the positioning rod 26 can accurately enter the positioning hole 27 to restrict the sealing plate 21.

[0069] In use, after adding chemical raw materials and liquid to beaker 3, pull the pull rod 36. The pull rod 36 moves the movable block 24, L-shaped block 25 and positioning rod 26 to a position that does not affect the rotation of sealing plate 21. Then, rotate sealing plate 21 and sealing gasket around the hinge to the top of beaker 3. Then, release the pull rod 36. The elastic force generated by squeezing spring 31 pushes the movable block 24, L-shaped block 25 and positioning rod 26 to move, so that positioning rod 26 enters the positioning hole 27, thereby restricting the position of sealing plate 21 and preventing liquid from overflowing from beaker 3 during stirring. Then, start motor 4. Motor 4 drives rotating rod 5 to rotate. Rotating rod 5 drives rotating block 6 and fan blade 7 to stir the liquid, thereby generating centrifugal force, so that chemical raw materials can quickly mix with liquid.

[0070] While rotating block 6 rotates, it drives the missing gear 8 to rotate. When the toothed end of missing gear 8 contacts and meshes with toothed plate 11, it drives toothed plate 11, push plate 10 and sliding block 29 to move along the trajectory of sliding groove 30 to the side closer to the inner wall of beaker 3. At the same time, it causes return spring 9 to be in a locked state. When missing gear 8 rotates to the point where the toothed end does not contact toothed plate 11, the push plate 10 will move along the trajectory of sliding groove 30 to the side away from beaker 3 due to the elastic force of return spring 9. This reciprocating motion stirs the liquid in beaker 3 by moving horizontally back and forth, further improving the mixing effect.

[0071] During the reciprocating motion of the push plate 10, the first connecting block 32 moves along with the push plate 10. At the same time, the first connecting block 32 pulls the swing arm 33 to move. The swing arm 33 rotates adaptively around the axis and pulls the second connecting block 34 and the swing plate 35 to move up and down, so that the liquid and chemical raw materials are mixed and have the function of stirring up and down, thus improving the mixing effect.

[0072] Furthermore, when the push plate 10 moves closer to the beaker 3, it drives the extrusion rod 15, extrusion plate 14, and piston 13 to move. At this time, the inside of the collection tank 12 is like a syringe, and the mixed liquid enters the collection tank 12 through the one-way inlet pipe 16. Then, when the return spring 9 drives the push plate 10 to move away from the inner wall of the beaker 3, the push plate 10 drives the extrusion rod 15, extrusion plate 14, and piston 13 to move, compressing the mixed liquid inside the collection tank 12. When the one-way pressure valve on the one-way drain pipe 17 reaches its limit, the mixed liquid will be sprayed upward from the one-way drain pipe 17, driving the liquid to flow towards the stirring mechanism, thereby improving the stirring effect.

[0073] Meanwhile, during the process of spraying liquid through the one-way drain pipe 17, the upward movement of the mixed liquid drives the rotating blade 20 and the rotating block 19 to rotate, further increasing the upward force of the liquid. At the same time, the rotation of the rotating blade 20 can also improve the stirring effect.

[0074] Example 2:

[0075] Please see Figure 10 When mixing the liquid inside beaker 3, the aforementioned technologies lack the function of adjusting the swing height of the swing plate 35 when the liquid volume inside beaker 3 changes. Furthermore, during prolonged use, raw materials easily adhere to the inner wall of beaker 3 and the outer surface of the swing plate 35, and the aforementioned technologies lack the function of scraping off the raw materials adhering to the bottom of beaker 3 and the outer surface of the swing plate 35, thus reducing the adaptive adjustment function for mixing, stirring, and cleaning the liquid inside beaker 3. When liquid is discharged into beaker 3 solely by the one-way drain pipe 17 and the rotating blade 20 is driven to rotate, the return flow rate and flow rate of the liquid inside beaker 3 are constant, which reduces the mixing effect. Additionally, raw materials easily adhere to the outer surface of the rotating blade 20, reducing the stirring and mixing impact effect. Moreover, when the degree of mixing of the liquid inside beaker 3 does not meet the concentration value detected by the liquid concentration sensor, the aforementioned devices lack the function of adjusting the liquid mixing.

[0076] To address the aforementioned issues, the surfactant quantitative detection component for sterilized tableware further includes: elastic extrusion blocks 40 on both sides of the swing plate 35, and splicing blocks 41 on the side of the one-way drain pipe 17 near the swing plate 35. The splicing blocks 41 match the elastic extrusion blocks 40. Therefore, when the swing plate 35 moves up and down continuously on the inner wall of the beaker 3, the swing plate 35 drives the elastic extrusion blocks 40 to move up and down synchronously. The elastic extrusion blocks 40 can not only press against the rotating blade 20 and drive the rotating blade 20 to vibrate and adjust for cleaning, but also, when the elastic extrusion blocks 40 and the splicing blocks 41 press against each other, they will drive the splicing blocks 41 to press against the one-way drain pipe 17 synchronously. This changes the opening size of the one-way drain pipe 17, thereby achieving pulsed drainage of the one-way drain pipe 17. This effectively improves the impact mixing effect between the one-way drain pipe 17 and the liquid inside the beaker 3, and also improves the pulse cleaning effect of the liquid discharged from the one-way drain pipe 17 on the outer surface of the swing plate 35.

[0077] The side wall of beaker 3 is provided with a baffle 42, which matches the side wall of the one-way drain pipe 17 away from the swing plate 35. The inner bottom of beaker 3 is provided with multiple sets of detection heads 43. The side wall of the one-way drain pipe 17 is blocked by the baffle 42, so that when the elastic extrusion block 40 is extruded, the corresponding one-way drain pipe 17 undergoes elastic deformation. The detection head 43 realizes the detection function after the liquid inside beaker 3 is mixed.

[0078] In use, the liquid to be tested and the chemical reagents are first added into the beaker 3, and the top of the beaker 3 is sealed with the sealing mechanism. Then, the controller controls the motor 4 to start and drive the rotating rod 5 to rotate. The rotating rod 5 drives the fan blade 7 to rotate through the rotating block 6, thereby stirring the liquid inside the beaker 3 and further improving the mixing effect of the liquid inside.

[0079] When the rotating block 6 rotates, it drives the missing gear 8 at the bottom to rotate. The missing gear 8 meshes with the toothed plate 11, causing the electric telescopic rod 39 and the push plate 10 to move away from each other. At this time, the extension distance of the electric telescopic rod 39 is the initial distance. When the missing gear 8 disengages from the toothed plate 11, the push plate 10 moves closer to each other and back to the initial position under the elastic force of the return spring 9. In turn, the lateral movement of the push plate 10 inside the beaker 3 improves the lateral stirring and mixing effect of the liquid inside the beaker 3.

[0080] When the push plate 10 moves to the ends that are far apart, the push plate 10 drives the swing plate 35 to move upward through the first connecting block 32, the swing arm 33 and the second connecting block 34. When the push plates 10 move closer to each other, they drive the swing plate 35 to move downward. The continuous up and down movement of the swing plate 35 effectively improves the mixing effect of the liquid inside the beaker 3.

[0081] Furthermore, when the two push plates 10 move away from each other, the squeeze rod 15 drives the squeeze plate 14 and piston 13 to move away from the end of the beaker 3 inside the collection tank 12. The pressure inside the collection tank 12 decreases, and under the action of negative pressure, the liquid inside the beaker 3 is drawn back to the collection tank 12 along the one-way liquid inlet pipe 16 for temporary storage. When the two push plates 10 move closer to each other, the push plate 10 drives the piston 13 to move closer to the side wall of the beaker 3 inside the collection tank 12. The pressure inside the collection tank 12 increases, and the liquid inside the collection tank 12 is discharged back into the beaker 3 along the one-way liquid outlet pipe 17 with the help of this pressure. This effectively achieves the upward backflow of the liquid at the bottom of the beaker 3, and the rotation of the fan blade 7 improves the stirring and mixing effect of the liquid, preventing the liquid inside the beaker 3 from accumulating at the bottom for a long time.

[0082] When the one-way drain pipe 17 discharges upward, it will drive the rotating blade 20 to rotate. The rotation of the rotating blade 20 accelerates the upward flow of the liquid, thereby improving the impact mixing effect between the liquid and the fan blade 7.

[0083] Simultaneously, when the push plates 10 approach each other and drive the swing plate 35 to move downward, the push plates 10 simultaneously drive the piston 13 to move inside the liquid collection tank 12 and squeeze the internal liquid. The liquid inside the liquid collection tank 12 is then discharged along the one-way drain pipe 17 and drives the rotating blade 20 to rotate. When the swing plate 35 moves downward and drives the elastic squeezing blocks 40 on both sides downward, the elastic squeezing blocks 40 first squeeze and collide with the rotating blade 20. With the help of this collision, the rotating blade 20 vibrates, thereby effectively cleaning the impurities attached to the outer surface of the rotating blade 20, improving the cleanliness and stability of the outer surface of the rotating blade 20. At the same time, the vibration of the rotating blade 20 can also guide the irregular turbulent flow of the liquid discharged from the one-way drain pipe 17, thereby improving the mixing and impact effect of the liquid flowing back from the bottom of the beaker 3 along the one-way drain pipe 17 to the surface of the beaker 3.

[0084] As the elastic extrusion block 40 continues to move downward and passes the rotating blade 20, the elastic extrusion block 40 and the splicing block 41 on the side wall of the one-way drain pipe 17 continuously squeeze and misalign with each other. When the elastic extrusion block 40 and the splicing block 41 are directly squeezing each other, the splicing block 41 is subjected to extrusion force and moves away from the swing plate 35. When the splicing block 41 moves, it simultaneously squeezes the one-way drain pipe 17, causing the opening of the one-way drain pipe 17 to decrease. As a result, the flow rate of the liquid discharged along the one-way drain pipe 17 increases. This change in flow rate, combined with the rotation of the rotating blade 20, increases the height of the liquid sprayed upward along the beaker 3, thereby improving the mixing effect with the liquid inside the beaker 3.

[0085] As the swing plate 35 moves downward and misaligns with the splicing block 41, the squeezing force on the splicing block 41 decreases. Under the elastic force of the one-way drain pipe 17, the opening of the one-way drain pipe 17 returns to normal, and the flow rate of the liquid discharged along the one-way drain pipe 17 returns to normal. As the elastic squeezing block 40 continuously squeezes and collides with multiple sets of splicing blocks 41, the opening of the one-way drain pipe 17 continuously changes, and the flow rate of the liquid discharged from the one-way drain pipe 17 continuously changes, thereby realizing the discharge of pulsed liquid along the one-way drain pipe 17. This causes a vibration-like transmission inside the beaker 3. With the help of this vibration transmission, the mixing and stirring effect of the liquid inside the beaker 3 can be effectively improved. At the same time, the swing plate 35 and the inside of the beaker 3 can be pulsed cleaned, effectively improving the cleanliness and stability of the internal structure of the beaker 3 and preventing the adhesion of impurities inside the liquid from reducing the mixing effect.

[0086] Simultaneously, when the liquid volume inside beaker 3 varies, the liquid concentration is detected by multiple liquid concentration detectors on the same vertical plane. When the concentration value detected by a liquid concentration detector at a certain height is zero, it indicates that there is no liquid at that height. Therefore, by using multiple liquid concentration detectors, the liquid height can be detected quickly and efficiently, and the maximum swing height of the swing plate 35 can be adjusted accordingly to prevent the swing plate 35 from pushing the liquid surface and causing liquid to splash outward when it swings upward. When the detected liquid level drops, the controller controls the electric telescopic rod 39 to start shortening, and the output end of the electric telescopic rod 39 drives the push... When the plates 10 move toward each other, the distance between the two push plates 10 decreases in the initial position. When the missing gear 8 meshes with the toothed plate 11 and moves toward each other through the electric telescopic rod 39, the push plates 10 move the same distance. When the push plates 10 move to the maximum position, the distance between the push plates 10 and the inner wall of the beaker 3 increases. With the help of the first connecting block 32, the swing arm 33 and the second connecting block 34, the maximum height of the swing plate 35 moving upward decreases, thereby ensuring that the maximum height of the swing plate 35 is still below the liquid surface, effectively improving the mixing and stirring effect of the liquid inside the beaker 3.

[0087] When the liquid inside beaker 3 is continuously stirred, but the mixing effect of the liquid does not meet the requirements due to various reasons, the concentration values ​​detected by the liquid concentration detector at various heights are not equal. Therefore, it is necessary to adjust the mixing efficiency of the liquid inside beaker 3. The controller controls the electric telescopic rod 39 to start and extend. The electric telescopic rod 39 drives the initial distance between the two sets of push plates 10 to increase. When the push plates 10 move to the maximum distance on both sides, the smaller the distance between the push plates 10 and the side wall of beaker 3, the greater the impact force between the liquid and the inner wall of beaker 3 caused by the pushing action of the push plates 10. Under the obstruction of the inner wall of beaker 3, the liquid is driven to move upward and the impact force with the swing plate 35 increases, thereby correspondingly improving the mixing efficiency and mixing effect of the liquid flowing upward back inside beaker 3.

[0088] Furthermore, as the distance between the two sets of push plates 10 increases from their initial positions, when the two sets of push plates 10 move toward each other, since the actual reciprocating distance of the push plates 10 is the same, the distance the piston 13 reciprocates inside the liquid collection tank 12 is the same, and the amount of liquid discharged from the liquid collection tank 12 along the one-way drain pipe 17 is the same. However, since the maximum height of the push plates 10 driving the swing plate 35 is different, the distance between the one-way drain pipe 17 and the maximum height of the rotating blade 20 and the swing plate 35 is different, and the extrusion time of the elastic extrusion block 40 is different from that of the rotating blade 20 and the splicing block 41. This effectively changes the time and position of the pulse liquid discharged from the one-way drain pipe 17, effectively realizing irregular mixing and stirring, with stronger adaptability and higher stability.

[0089] Therefore, by controlling the extension length of the electric telescopic rod 39 to change, the initial position of the push plate 10 can be adjusted when mixing the liquid inside the beaker 3, and the maximum swing height of the swing plate 35 and the pulse spray time of the one-way drain pipe 17 can be adjusted accordingly, resulting in stronger adaptability, higher stability, and better adjustability.

[0090] After the mixing of the liquid inside beaker 3 is completed, the controller controls the motor 4 to stop working when the gear 8 disengages from the gear plate 11, and the electric telescopic rod 39 is activated and shortened to its minimum distance. Then, the piston 13 moves to the end closest to beaker 3 inside the liquid collection tank 12. The liquid inside the liquid collection tank 12 is discharged along the one-way drain pipe 17, and the liquid inside beaker 3 is detected by multiple sets of detection heads 43. After the detection is completed, the water valve 38 is opened to drain the liquid inside beaker 3. After the draining is completed, the motor 4 can be restarted, and the above process can be repeated when there is no liquid inside beaker 3, thereby realizing the air pulse cleaning inside beaker 3 and ensuring the cleanliness and dryness of each structure.

[0091] This device is simple to operate and highly adjustable. It can perform one-time mixing and stirring detection of the liquid inside beaker 3, and can stir the liquid horizontally, vertically, and circumferentially during the stirring process, resulting in more uniform and thorough mixing. At the same time, it can also reflux the liquid at the bottom of beaker 3 upwards to prevent the liquid inside beaker 3 from settling. In actual mixing and stirring, it can also realize pulse reflux of the liquid, which is more effective in cleaning and mixing. Furthermore, the extension length of the electric telescopic rod 39 can be adjusted according to the liquid level inside beaker 3 and the mixing effect at various heights, thereby adjusting the mixing efficiency, making it more adaptable, more stable, and better in mixing.
