Description

Technical Field

[0001] This utility model relates to the field of proportioning device technology, and in particular to a proportioning device for the production of antibacterial liquid. Background Technology

[0002] Antibacterial liquids are a type of liquid product that inhibits the growth and reproduction of microorganisms. Their core function is to interfere with the metabolic processes, cell structure, or physiological functions of microorganisms through specific active ingredients, thereby slowing down or preventing the growth of microorganisms.

[0003] In the field of antibacterial liquid production, professional proportioning devices are required. These devices are usually based on a tank with a sealed structure, with a weighing module at the bottom that can monitor the total weight of the materials in the tank in real time. Combined with the preset proportions of each raw material, the feeding amount is automatically adjusted to ensure the accuracy of raw material addition. At the same time, the proportioning device is equipped with a stirring mechanism that can fully blend multiple raw materials through high-speed rotation or circulation mixing, avoiding deviations in antibacterial effect caused by uneven local concentrations.

[0004] To ensure the quality of the final product, the antibacterial liquid mixed in the tank needs to be sampled and tested multiple times during the production process. The test indicators include the content of active ingredients, pH value, microbial inhibition rate, and clarity. These data are the core basis for quality control in the production process and directly determine whether it can enter the next production stage or whether the finished product is qualified.

[0005] When sampling is required, operators need to open the valves pre-set on the side wall or bottom of the tank to allow the antibacterial liquid inside to flow out naturally along the sampling pipe, and then collect it with a sampling container. In order to enable the antibacterial liquid to directly enter the subsequent filtration, filling and other processes after the proportioning is completed, the discharge valve of some proportioning devices will be directly connected to the subsequent production pipeline, forming a continuous transport path from the proportioning tank to the subsequent pipeline. When it is necessary to sample and test the proportioned antibacterial liquid, operators cannot directly obtain samples through the conventional discharge valve. If the valve is opened directly, the antibacterial liquid will flow to the downstream process along the subsequent production pipeline. Not only will it be impossible to collect a sufficient amount of sample, but the feed amount of the subsequent process may also be out of control due to the premature transport of materials. If the connection between the discharge valve and the subsequent pipeline is temporarily disconnected for sampling, the operation process is troublesome and increases the burden on the staff. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a proportioning device for the production of antibacterial liquid. This solves the problem that in some proportioning devices, the discharge valve is directly connected to the subsequent production pipeline, forming a continuous transport path from the proportioning tank to the subsequent pipeline. When sampling and testing of the proportioned antibacterial liquid is required, operators cannot directly obtain samples through the conventional discharge valve. If the valve is opened directly, the antibacterial liquid will flow downstream along the production pipeline, resulting in insufficient sample collection and potential loss of control over the feed rate in subsequent processes due to premature material transport. Temporarily disconnecting the discharge valve from the subsequent pipeline for sampling is cumbersome and increases the workload for staff.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A mixing device for producing an antibacterial liquid includes a tank. A sampling tube for sampling is fixedly installed on the outside of the tank and communicates with the inside of the tank. A sealing block is slidably connected inside the sampling tube. A power mechanism for limiting the position of the sealing block is provided outside the sampling tube. The power mechanism includes an electric push rod and a control box. The output shaft of the electric push rod is fixedly installed outside the sealing block. The control box is electrically connected to the electric push rod. A collection mechanism for collecting samples is provided below the sampling tube. The collection mechanism includes a sample outlet, a threaded cylinder, and a collection cylinder. The sample outlet is located outside the sampling tube and communicates with the inside of the sampling tube. One end of the threaded cylinder is fixedly installed on the side of the sampling tube corresponding to the sample outlet. The end of the collection cylinder is threadedly connected to the inside of the threaded cylinder.

[0009] Preferred configuration: The electric push rod is externally bolted to a connecting plate, and two screw rods are fixedly installed on the outside of the tank. Each screw rod is threaded with a nut, and the connecting plate is slidably connected to the outside of the two screw rods.

[0010] Preferably, the upper surface of the connecting plate is provided with a positioning groove, the bottom of the control box is snapped into the inside of the positioning groove, both ends of the connecting plate are provided with threaded holes, the threaded holes are connected to the inside of the positioning groove, each threaded hole is threaded with a threaded rod, and the end of each threaded rod is fitted with an isolation pad.

[0011] Preferably, a sealing ring is provided on the outside of the sealing block, and an annular groove is opened on the outside of the sealing block, with the sealing ring snapped into the inside of the annular groove.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] By pressing the control box to move the electric push rod, the channel connecting the sampling tube and the inside of the tank is opened, and the antibacterial liquid inside the tank flows into the sampling tube. The antibacterial liquid flows along the inner wall of the sampling tube and then flows smoothly into the collection cylinder through the sample outlet. When enough sample is collected, the output shaft of the push rod drives the sealing block to slide closer to the tank until the sealing block is completely reset, resealing the port connecting the sampling tube and the tank. At this time, the sampling tube stops feeding liquid, and the operator holds the collection cylinder to disconnect the connection between the collection cylinder and the threaded cylinder. Sampling can be completed without opening the valve, which will not cause the antibacterial liquid in the tank to flow into the downstream process in advance. This solves the problem of uncontrolled feed volume in subsequent processes that may be caused by traditional sampling methods. At the same time, it eliminates the need to disassemble pipe interfaces or perform complex mechanical operations, simplifying the sampling operation steps and reducing the labor intensity and operational burden of the staff.

[0023] This application provides a proportioning device for antibacterial liquid production, which effectively solves the problem that some proportioning devices have their discharge valves directly connected to subsequent production pipelines, forming a continuous transport path from the proportioning tank to the subsequent pipeline. When it is necessary to sample and test the proportioned antibacterial liquid, the operator cannot directly obtain the sample through the conventional discharge valve. If the valve is opened directly, the antibacterial liquid will flow to the downstream process along the subsequent production pipeline. Not only will it be impossible to collect a sufficient amount of sample, but the material may also cause the feed rate of the subsequent process to become out of control due to premature material transport. If the connection between the discharge valve and the subsequent pipeline is temporarily disconnected for sampling, the operation process is cumbersome and increases the burden on the staff.

[0024] Example

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the technical solution in this application embodiment effectively solves the problem that the discharge valve of some proportioning devices is directly connected to the subsequent production pipeline, forming a continuous conveying path from the proportioning tank to the subsequent pipeline. When it is necessary to sample and test the proportioned antibacterial liquid, the operator cannot directly obtain the sample through the conventional discharge valve. If the valve is opened directly, the antibacterial liquid will flow to the downstream process along the subsequent production pipeline. Not only will it be impossible to collect a sufficient amount of sample, but it may also cause the feed rate of the subsequent process to become out of control due to the premature delivery of materials. If the connection between the discharge valve and the subsequent pipeline is temporarily disconnected for sampling, the operation process is cumbersome and increases the burden on the staff. The overall approach is as follows:

[0026] To address the problems existing in the prior art, this utility model provides a mixing device for producing antibacterial liquid, including a tank 1. A sampling tube 2 for sampling is fixedly installed on the outside of the tank 1. The sampling tube 2 communicates with the inside of the tank 1. A sealing block 3 is slidably connected inside the sampling tube 2. A power mechanism for limiting the position of the sealing block 3 is provided on the outside of the sampling tube 2. The power mechanism includes an electric push rod 4 and a control box 5. The output shaft of the electric push rod 4 is fixedly installed on the outside of the sealing block 3. The control box 5 is electrically connected to the electric push rod 4.

[0027] A collection mechanism for collecting samples is provided below the sampling tube 2. The collection mechanism includes a sample outlet 6, a threaded cylinder 7, and a collection cylinder 8. The sample outlet 6 is located on the outside of the sampling tube 2 and communicates with the inside of the sampling tube 2. One end of the threaded cylinder 7 is fixedly installed on the side of the sampling tube 2 corresponding to the sample outlet 6. The end of the collection cylinder 8 is threadedly connected to the inside of the threaded cylinder 7. The collection cylinder 8 is made of transparent material, which makes it easy for staff to observe the sample volume.

[0028] The electric push rod 4 is externally bolted to a connecting plate 9. Two screws 10 are fixedly installed on the outside of the tank body 1. Each screw 10 is externally threaded with a nut 11. The connecting plate 9 is slidably connected to the outside of the two screws 10.

[0029] The upper surface of the connecting plate 9 is provided with a positioning groove 12, and the bottom of the control box 5 is snapped into the inside of the positioning groove 12.

[0030] Both ends of the connecting plate 9 are provided with threaded holes 13, which are connected to the interior of the positioning groove 12. Each threaded hole 13 is threaded with a threaded rod 14, and each threaded rod 14 is fitted with an isolation pad 15 at its end. The isolation pad 15 is made of silicone. The isolation pad 15 at the end of the threaded rod 14 fixes the control box 5 by pressing the bottom of the control box 5, preventing the control box 5 from shaking during use.

[0031] A sealing ring 16 is provided on the outside of the sealing block 3, and an annular groove 17 is provided on the outside of the sealing block 3. The sealing ring 16 is snapped into the inside of the annular groove 17. The sealing ring 16 is snapped into the outside of the sealing block 3 through the annular groove 17, which enhances the sealing performance between the sealing block 3 and the inner wall of the sampling tube 2, and prevents the liquid inside the tank 1 from leaking through the sampling tube 2 when not sampling.

[0032] Working principle:

[0033] The first step is to operate the electric push rod 4 by pressing the retraction button on the control box 5 when sampling is required. The output shaft of the electric push rod 4 drives the sealing block 3 to slide away from the tank 1. As the sealing block 3 moves, the channel connecting the sampling tube 2 and the inside of the tank 1 is opened. Because the stirring device inside the tank 1 continues to operate, the antibacterial liquid inside the tank 1 flows into the sampling tube 2 under the action of the stirring force. The antibacterial liquid flowing into the sampling tube 2 will flow along the inner wall of the sampling tube 2. When it reaches the sampling port 6, because the sampling port 6 is connected to the inside of the sampling tube 2, the antibacterial liquid will flow smoothly into the collection cylinder 8 through the sampling port 6. The operator can observe the flow according to the sampling requirements. When enough sample is collected, press the extension button on the control box 5. The control box 5 will send an electrical signal to the electric push rod 4 again. The output shaft of the electric push rod 4 will drive the sealing block 3 to slide closer to the tank 1 until the sealing block 3 is completely reset and re-seals the port connecting the sampling tube 2 and the tank 1. At this time, the sampling tube 2 will stop feeding liquid. After sampling is completed, the operator will hold the collection tube 8 and rotate the collection tube 8 counterclockwise to gradually disengage the threaded connection between the collection tube 8 and the threaded tube 7. When the collection tube 8 is completely separated from the threaded tube 7, the collection tube 8 can be removed and the collected antibacterial liquid sample can be sent to the testing department for testing of components, concentration and other indicators.

[0034] The second step is to ensure that the tank 1 is stopped when the power mechanism needs to be repaired. Turn the nut 11 to disconnect the nut 11 from the screw 10. At this time, the connecting plate 9 can be pulled to disconnect the connecting plate 9 from the screw 10. The power mechanism can then be removed from the tank 1. After the power mechanism is removed, the electric push rod 4 and the control box 5 can be repaired. If the control box 5 needs to be repaired separately, the threaded rod 14 in the threaded holes 13 at both ends of the connecting plate 9 can be turned. As the threaded rod 14 is turned, the isolation pad 15 will gradually move away from the bottom of the control box 5. At this time, the control box 5 can be removed from the positioning groove 12 for separate repair. After the repair is completed, the bottom of the control box 5 is re-clamped into the positioning groove 12. The threaded rod 14 is turned in the opposite direction to make the isolation pad 15 fit tightly against the bottom of the control box 5, and the control box 5 is firmly fixed in the positioning groove 12 to prevent the control box 5 from shaking during subsequent use.

[0035] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
