Abstract
Description
Technical Field
[0001] This utility model relates to the field of industrial solution concentration adjustment technology, and in particular to a hypochlorous acid disinfectant mixing method production device. Background Technology
[0002] In current industrial and laboratory environments, hypochlorous acid disinfectant, as a widely used key disinfectant, still relies primarily on the direct purchase of pre-diluted finished products. Finished disinfectant solutions typically have high unit prices due to the inclusion of packaging, transportation, and intermediate costs. Furthermore, the large volume of water in the finished solution increases the weight and volume of logistics, making transportation and storage costs particularly prominent. For medical institutions, food processing plants, water treatment facilities, or research laboratories with high disinfectant consumption, long-term purchases of finished products will undoubtedly drive up operating expenses. In contrast, if the purchase of high-concentration hypochlorous acid stock solution (or stable precursor substances) could be changed, and on-site dilution and preparation could be carried out according to actual needs, raw material procurement costs and logistics expenses could be significantly reduced from the source.
[0003] In existing on-site dilution and preparation processes, especially the traditional manual preparation method, operators usually need to rely on simple tools such as measuring cylinders and scales to manually calculate and measure high-concentration stock solutions and mix them with water. This method is not only characterized by low preparation accuracy and cumbersome and time-consuming procedures, but it is also prone to significant errors due to human reading errors, inconsistent operations, or environmental interference, resulting in poor concentration stability between batches. When dealing with highly corrosive and strongly oxidizing hypochlorous acid stock solutions, manual operation also increases the safety risk of operators coming into contact with hazardous chemicals, and volatile gases may affect the working environment. In addition, manual preparation makes it difficult to achieve accurate process recording, real-time monitoring, and data traceability, which cannot meet the strict requirements of modern automated production lines, intelligent warehouses, or high-standard clean areas for the stability of disinfectant supply, repeatability of preparation, and safety control throughout the entire process.
[0004] Therefore, how to provide a hypochlorous acid disinfectant mixing method production device is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content
[0005] One objective of this invention is to provide a hypochlorous acid disinfectant mixing method production device, which solves the problems mentioned in the background art.
[0006] A hypochlorous acid disinfectant mixing method production device according to an embodiment of the present invention includes a cabinet shell. A touch screen for human-computer interaction is fixedly installed on one side of the cabinet shell near the top. The interior of the cabinet shell is divided into a first chamber, a second chamber, and a third chamber by a partition plate. An installation plate is fixedly installed on the inner wall of the first chamber, and a raw liquid tank is movably installed inside the first chamber on one side of the installation plate. A water outlet and a water inlet are respectively preset on the side of the cabinet shell corresponding to the positions of the second and third chambers. A mixing component is fixedly installed inside the second chamber, and a liquid inlet component is fixedly installed inside the third chamber. One end of the liquid inlet component is fixedly connected to one end of the mixing component, and the other end of the liquid inlet component is fixedly connected and communicates with the water inlet. The other end of the mixing component is fixedly connected and communicates with the water outlet. A power interface is fixedly installed on the back of the cabinet shell near the bottom.
[0007] A top cover is movably installed on the top of the cabinet shell, directly above the original liquid tank, and a handle is fixedly installed on the top of the top cover.
[0008] Four casters are fixedly installed at the bottom of the cabinet shell.
[0009] The liquid inlet assembly includes a metering pump body, a three-way pipe, a solenoid valve, an injection valve, a check valve, and a metering pump body mounting bracket. The metering pump body mounting bracket is fixedly installed at the bottom of the inner wall of the third chamber. One end of the three-way pipe is fixedly connected to one end of the metering pump body, and the solenoid valve is fixedly connected to the other end of the three-way pipe. The upper end of the solenoid valve is fixedly connected to and communicates with the raw liquid tank through a Teflon tube one. The left end of the three-way pipe is fixedly connected to and communicates with the port of the injection valve through a Teflon tube two. One end of the check valve is fixedly connected to and communicates with the water inlet. The bottom end of the metering pump body is fixedly connected to and communicates with the raw liquid tank through a Teflon tube three.
[0010] The mixing assembly includes a reaction vessel and a detection chamber. The reaction vessel is fixedly installed on the inner wall of the second chamber. The top ends of the check valve and the injection valve extend through the partition plate into the interior of the second chamber and are fixedly connected to the bottom end of the reaction vessel. One end of the detection chamber is fixedly connected to the top end of the reaction vessel through a bent pipe.
[0011] The mixing assembly also includes a sensor interface and a detection chamber plug. The sensor interface is located on the side of the detection chamber, and the detection chamber plug is fixedly installed on both sides of the detection chamber. The surface of the detection chamber plug has a water outlet hole, which is fixedly connected to the water outlet through a pipeline.
[0012] The surface of the detection cavity is fitted with a saddle clip, and the bottom end of the saddle clip is fixedly connected to the bottom of the inner wall of the second cavity.
[0013] The sensor interface consists of two sets, with sensors threaded onto each set of interfaces.
[0014] The number of plugs in the detection chamber is also two sets, with the water inlet hole of the left detection chamber plug being lower and the water inlet hole of the right detection chamber plug being higher, forming a low inlet and high outlet.
[0015] The beneficial effects of this utility model are:
[0016] By integrating the metering pump body, solenoid valve, injection valve and check valve and other liquid inlet components, the automated and accurate metering and mixing of raw liquid and water is realized, replacing the traditional manual measurement and calculation method. This effectively eliminates human reading errors and operational inconsistencies, thereby significantly improving the preparation accuracy and production efficiency of hypochlorous acid disinfectant, and ensuring the stability of concentration between batches.
[0017] The device features a closed cabinet design, housing the raw liquid tank, mixing components, and inlet components in the first, second, and third chambers, respectively. Remote human-machine interaction is achieved via a touchscreen, preventing operators from directly contacting the highly corrosive and oxidizing hypochlorous acid raw liquid and its volatile gases, significantly reducing safety risks and improving the working environment.
[0018] Through the interactive interface of the touch screen and the sensor interface set on the detection chamber, users can monitor key parameters in the mixing process in real time and realize the automatic recording and storage of preparation data, which meets the traceability and intelligent management and control requirements of modern automated production lines or high-standard clean areas for the entire process of disinfectant supply.
[0019] The mixing assembly adopts a combination structure of a reaction vessel and a detection chamber, and utilizes the low-inlet and high-outlet design of the detection chamber plug to ensure that the mixed liquid flows fully and reacts evenly in the detection chamber. Combined with real-time feedback from sensors, this further improves the consistency and reliability of the output disinfectant quality. Attached Figure Description

[0025] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.
[0026] Example 1
[0027] refer to Figure 1-3 In this embodiment, a cabinet shell 1 is included. A touchscreen 11 for human-computer interaction is fixedly installed on one side of the cabinet shell 1 near the top. The interior of the cabinet shell 1 is divided into a first chamber, a second chamber, and a third chamber by a partition plate. Figure 1 As shown, there are two horizontally arranged partitions that divide the interior of the cabinet shell 1 into three nearly identical chambers: a first chamber, a second chamber, and a third chamber. This separates different components, preventing interference during operation. This design also allows for quick location of the corresponding components and improves maintenance convenience. A mounting plate is fixedly installed on the inner wall of the first chamber, with several evenly spaced mounting holes for installing a control board. This control board is based on existing technology. Inside the first chamber, a liquid reservoir 17 is movably installed on one side of the mounting plate. The top of the cabinet shell 1 is located at the liquid reservoir... A top cover 13 is movably installed directly above the compartment 17. A handle 131 is fixedly installed on the top of the top cover 13. The handle 131 is used to lift the top cover 13 upwards. An opening is opened on the top of the outer shell 1 of the cabinet corresponding to the position of the original liquid compartment 17. This opening is larger than the size of the original liquid compartment 17, so as to facilitate the placement of the original liquid compartment 17. A positioning seat is fixedly installed at the bottom of the inner wall of the first chamber, corresponding to the position of the original liquid compartment 17. A top seat is also fixedly installed at the bottom of the top cover 13 corresponding to the original liquid compartment 17. The top seat and the positioning seat are a ring seat, which is used to lock the top and bottom of the original liquid compartment 17 to improve the stability of the original liquid compartment 17. The top cover 13 is tightly locked with the top opening.
[0028] The outer side of the cabinet shell 1 has a water outlet 15 and a water inlet 14 respectively, corresponding to the positions of the second and third chambers. A liquid inlet assembly 2 is fixedly installed inside the third chamber. The liquid inlet assembly 2 is used to introduce liquid. The liquid inlet assembly 2 includes a metering pump body 21, a three-way pipe 22, a solenoid valve 23, an injection valve 24, a check valve 25, and a mounting bracket for the metering pump body 21. The mounting bracket for the metering pump body 21 is fixedly installed on the bottom of the inner wall of the third chamber, securing the metering pump body 21 stably. It is fixed with screws for easy disassembly and maintenance. One end of the three-way pipe 22 is fixedly connected to one end of the metering pump body 21. The shape of the three-way pipe 22 is as follows: Figure 2 and Figure 3 As shown, the other end of the solenoid valve 23 is fixedly connected to the three-way pipe 22. The upper end of the solenoid valve 23 is fixedly connected to the raw liquid tank 17 through a Teflon tube 1. The left end of the three-way pipe 22 is fixedly connected to the port of the injection valve 24 through a Teflon tube 2. One end of the check valve 25 is fixedly connected to the water inlet 14. The bottom end of the metering pump body 21 is fixedly connected to the raw liquid tank 17 through a Teflon tube 3.
[0029] In practice, after the operator sets the target concentration and output parameters of the disinfectant via the touch screen 11, the system starts. External water is introduced through the inlet 14 and the check valve 25. Simultaneously, the high-concentration hypochlorous acid stock solution in the stock solution tank 17 is precisely extracted by the metering pump, transported through a Teflon tube, and regulated by the solenoid valve 23 and the three-way pipe 22. It is then injected into the reaction vessel 31 in the second chamber along with the water flow through the injection valve 24 at a preset ratio for thorough mixing. The generated hypochlorous acid disinfectant then enters the detection chamber 32, where sensors monitor the concentration and pH value in real time. The data is fed back to the control system to dynamically fine-tune the metering pump and the solenoid valve 23, achieving closed-loop control. Finally, the disinfectant that meets the standards is automatically output from the outlet 15 through the outlet hole of the detection chamber plug 323 and the pipeline. The internal space is clearly divided into three independent sections by two horizontal partitions. The chamber achieves physical isolation between the three functional modules of raw material storage, mixing reaction, and dynamic liquid inlet. This layout not only effectively avoids operational interference between electrical components and liquid pipelines, improving system stability, but also makes the positioning, maintenance, and replacement of each component extremely convenient. At the same time, the raw material tank 17 is bidirectionally secured by the positioning seat at the bottom and the top seat under the top cover 13. Combined with the tight design of the top cover 13, it ensures the sealing and safety of corrosive raw materials during storage and transportation. The overall structure takes into account both compactness and maintainability. It should be noted that during installation and maintenance, all Teflon pipeline connections should be ensured to be tight to prevent leakage. The raw material tank 17 should be lifted vertically by pulling the top cover 13 using the top handle 131 to avoid tilting. The operating environment of the device should be kept ventilated and dry to ensure the detection accuracy of the sensors and the long-term reliability of the electrical control system.
[0030] Example 2
[0031] refer to Figure 1-3 In this embodiment, a mixing assembly 3 is fixedly installed inside the second chamber. As the name suggests, the mixing assembly 3 is a component for mixing solutions. Here, the solution in the original liquid tank 17 and the solution entering through the inlet 14 are mixed into the mixing assembly according to a preset ratio. The preset mixing is controlled by built-in software. Both the software and the control board are mature technologies in this field and work according to the working principle of this technical solution. The preset can be controlled by touch screen 11. The mixing assembly 3 includes a reaction vessel 31 and a detection chamber 32. The reaction vessel 31 is fixedly installed on the inner wall of the second chamber. The top ends of the check valve 25 and the injection valve 24 extend through the partition plate into the interior of the second chamber and are fixedly connected to the bottom end of the reaction vessel 31. One end of the detection chamber 32 is fixedly connected to the top end of the reaction vessel 31 through a bent pipe.
[0032] In practice, two different solutions are introduced into the reaction vessel 31 in a preset ratio, and then the solution after reaction in the reaction vessel 31 enters the detection chamber 32.
[0033] The mixing assembly 3 also includes a sensor interface 322 and a detection chamber plug 323. The sensor interface 322 is located on the side of the detection chamber 32. The detection chamber plug 323 is fixedly installed on both sides of the detection chamber 32. The surface of the detection chamber plug 323 has a water outlet hole, which is fixedly connected to the water outlet 15 through a pipeline. The detection chamber plug 323 facilitates the connection of the pipeline to the detection chamber 32 and then to the water outlet 15.
[0034] The surface of the detection cavity 32 is movably fitted with a saddle clip 321. The bottom end of the saddle clip 321 is fixedly connected to the bottom of the inner wall of the second cavity, which limits the detection cavity 32 and improves the stability of the detection cavity 32 in the second cavity. The saddle clip 321 is also fixed by screws for easy maintenance. The screws are of the same type to avoid increasing the complexity of operation by using different tools.
[0035] The number of sensor interfaces 322 is two sets, and sensors are threadedly installed on the two sets of sensor interfaces 322. The sensors are pH sensors and concentration sensors. One detects the concentration of available chlorine, and the other detects the pH value of the mixed solution.
[0036] The number of detection chamber plugs 323 is also two sets, with the water inlet hole of the left detection chamber plug 323 being lower and the water inlet hole of the right detection chamber plug 323 being higher, forming a low inlet and high outlet.
[0037] One end of the liquid inlet component 2 is fixedly connected to one end of the liquid mixing component 3, the other end of the liquid inlet component 2 is fixedly connected to and communicates with the water inlet 14, and the other end of the liquid mixing component 3 is fixedly connected to and communicates with the water outlet 15.
[0038] A power interface 16 is fixedly installed on the back of the cabinet shell 1 near the bottom. The power interface 16 is connected to the municipal power supply system through a wire. Four casters 18 are fixedly installed on the bottom of the cabinet shell 1 to facilitate moving the entire cabinet shell 1 to the desired position.
[0039] The overall design features a low inlet and high outlet, facilitating further mixing of the liquid.
[0040] The working principle of this utility model is as follows:
[0041] First, power is connected via the power interface 16 on the back of the cabinet shell 1. The touch screen 11 is activated and the preparation parameters of the disinfectant, such as concentration and flow rate, are set. The water inlet 14 is connected to an external water source. Hypochlorous acid stock solution is stored in the stock solution tank 17. During operation, the metering pump body 21 in the liquid inlet assembly 2 draws the stock solution from the stock solution tank 17 through the Teflon tube under the control signal. At the same time, external water flows in from the water inlet 14 through the check valve 25. The stock solution and water are precisely measured through the solenoid valve 23, the three-way tube 22, and the injection valve 24, respectively. After being measured and adjusted, the mixture is injected into the reaction vessel 31 of the mixing component 3 for mixing and reaction. The mixed liquid rises into the detection chamber 32, and the concentration and pH value are detected in real time by the sensor installed on the sensor interface 322. The detection chamber plugs 323 on both sides of the detection chamber 32 form a low inlet and high outlet flow path to ensure that the liquid fully contacts the detection element and avoids residue. Finally, the qualified hypochlorous acid disinfectant is output from the outlet hole of the detection chamber plug 323 through the pipeline from the outlet 15, completing the automated preparation process.
[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
