Description

Technical Field

[0001] The utility model relates to the technical field of sulfur dioxide detectors, in particular to a multifunctional food sulfur dioxide detector. Background Art

[0002] In the current processing of many foods and drugs, in order to achieve the effects of sterilization or aesthetics, many illegal vendors overdose use sulfur dioxide to fumigate products. And the sulfur dioxide remaining on the foods and drugs will cause great harm to the human body. Therefore, the State Food and Drug Administration has formulated strict detection standards to detect the sulfur dioxide residues in relevant foods or drugs.

[0003] In the prior art, as the Chinese patent publication number CN214585309U discloses a multifunctional food sulfur dioxide detector, which includes a device main body. A cleaning box is fixedly installed at the top of the device main body, and a motor box is fixedly installed at the top of the cleaning box; in this utility model, a certain amount of sample is put into the cleaning box, and then distilled water is injected. When the water level of the distilled water reaches the position of the water level gauge, the water level gauge transmits the detected signal to the controller, and the controller closes the first valve to avoid injecting too much water and affecting the detection effect. The motor drives the reduction gear to rotate, the reduction gear drives the connecting rotating shaft to rotate, the connecting rotating shaft drives the stirring rod to rotate, and then the stirring blades can drive the sample to rotate in the water, so that the residual sulfur dioxide on the sample can be dissolved in the water. Then the second valve is opened, so that the cleaning water can enter the detection box, and the instrument and equipment in the detection box are used to detect the content of sulfur dioxide in the water.

[0004] Although the above patent solves the problem that the motor drives the reduction gear to rotate, the reduction gear drives the connecting rotating shaft to rotate, the connecting rotating shaft drives the stirring rod to rotate, and then the stirring blades can drive the sample to rotate in the water, so that the residual sulfur dioxide on the sample can be dissolved in the water. Then the second valve is opened, so that the cleaning water can enter the detection box, and the instrument and equipment in the detection box are used to detect the content of sulfur dioxide in the water. However, for some foods that have been specially treated or contain complex components, stirring can only remove part of the sulfur dioxide on the surface. Because the removal of sulfur dioxide is a dynamic equilibrium process, while stirring, new sulfur dioxide may be released from the food interior, or remain on the food surface or in the gaps due to incomplete cleaning, thus affecting the accuracy and precision of the final detection. Therefore, in view of the above problems, we propose a new type of multifunctional food sulfur dioxide detector. Summary of the Utility Model

[0021] In order to more clearly understand the above-mentioned objects, features, and advantages of the present utility model, the present utility model will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0022] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0023] Embodiment 1: As Figures 1-4 shown, the present utility model provides a multifunctional food sulfur dioxide detector, which includes a cleaning tank 1. A top cover 2 is fixedly connected to the top of the cleaning tank 1. An installation frame 21 is fixedly connected to the top of the top cover 2 near the left side. A driving motor 22 is installed on the top of the installation frame 21. The output end of the driving motor 22 penetrates through the top of the top cover 2 and extends downward. A speed reducer 23 is fixedly installed at the bottom of the driving motor 22. A first gear 3 is fixedly connected to the bottom of the speed reducer 23. A stirring rod 31 is fixedly connected to the bottom of the first gear 3. A plurality of groups of stirring blades 32 are fixedly connected to the outer surface of the stirring rod 31 at equal intervals. A second gear 4 is rotatably connected to the top of the top cover 2 near the right side. A hollow shell 41 is fixedly communicated with the bottom of the second gear 4. A plurality of groups of hollow rods 42 are fixedly communicated with the outer surface of the hollow shell 41 at equal intervals. A plurality of nozzles 43 are fixedly connected to both outer surfaces of the plurality of groups of hollow rods 42. A protective sleeve 33 is fixedly sleeved on the outer surface of each group of stirring blades 32. A water injection pipe 12 is fixedly communicated with the top of the second gear 4 at a position not close to the middle. The outer surface of the water injection pipe 12 penetrates through the second gear 4 and its end is communicated with the hollow shell 41. A first valve 13 is installed on the outer surface of the water injection pipe 12. The first gear 3 is rotatably connected to the top cover 2. The first gear 3 and the second gear 4 are meshed. A feeding hopper 11 is installed on the top of the top cover 2 near the front side. A water level gauge 5 is arranged on the left surface of the cleaning tank 1 near the upper part. Three support legs 14 are fixedly connected to the bottom of the cleaning tank 1 at equal intervals near the edge. A detection box 51 is fixedly connected between the tops of the three support legs 14. A drain pipe 15 is fixedly communicated with the bottom of the cleaning tank 1 near the middle. A filter screen 16 is fixedly connected to the inner wall of the drain pipe 15 near the top. A second valve 52 is installed on the front surface of the drain pipe 15. A controller 53 is installed on the front surface of the cleaning tank 1.

[0024] The effect achieved by the entire Example 1 is that when using this device, the operator first puts a certain amount of food samples into the cleaning tank 1 through the feeding hopper 11. The design of the feeding hopper 11 facilitates the accurate and rapid entry of the samples into the cleaning tank 1 while reducing splashing. Subsequently, the operator injects distilled water into the cleaning tank 1 through the water injection pipe 12. As the cleaning medium, the distilled water can effectively remove the impurities and residual sulfur dioxide on the surface of the samples. During the water injection process, the water level gauge 5 continuously monitors the water level change. When the water level reaches the preset position, the water level gauge 5 transmits the detected signal to the controller 53. After receiving the signal, the controller 53 immediately closes the first valve 13 to stop the injection of distilled water and prevent the water level from being too high to affect subsequent operations. When it is necessary to clean the samples, the operator starts the cleaning program through the controller 53. After the program starts, the driving motor 22 on the mounting frame 21 is first driven to operate. After the speed of the driving motor 22 is reduced by the speed reducer 23, the first gear 3 is driven to rotate. The first gear 3 is fixedly connected to the stirring rod 31. Therefore, the stirring rod 31 and multiple groups of stirring blades 32 rotate accordingly. A protective sleeve 33 is fixedly sleeved on the outer surface of the stirring blade 32 to ensure that the cleaning tank 1 or the samples will not be scratched during the stirring process and improve the stirring efficiency at the same time. While the stirring blade 32 is rotating, the operator opens the first valve 13 on the water injection pipe 12 to inject cleaning water into the hollow shell 41 at the bottom of the second gear 4. The cleaning water enters multiple groups of hollow rods 42 through the hollow shell 41 and is sprayed in a uniform manner by the nozzles 43 to cover the entire cleaning area. Since the first gear 3 and the second gear 4 are in a meshing connection state, when the first gear 3 rotates forward driven by the driving motor 22, the second gear 4 will rotate in reverse. The water flow and stirring action generated by such forward and reverse rotations in different directions can stir the food samples more evenly, making the residual sulfur dioxide on their surfaces dissolve more fully in the water and improving the cleaning effect. After the cleaning is completed, the operator opens the second valve 52 on the drain pipe 15 through the controller 53. Under the control of the second valve 52, the cleaning water will pass through the filter screen 16 for filtration, flow into the detection tank 51 after removing large particle impurities, and then the sulfur dioxide detection instrument in the detection tank 51 is used to detect the food samples. The detection process may involve chemical reactions, photoelectric colorimetry or other advanced analysis techniques, depending on the type and principle of the detection instrument. After the detection is completed, the controller 53 will record and display the detection results for the operator to analyze and evaluate. This device effectively removes the residual sulfur dioxide on the surface of food samples through an automated cleaning and stirring system, ensuring the reliability of the detection results. The unique forward and reverse rotation stirring design enhances the cleaning effect and makes the sample cleaning more thorough. The top cover 2 ensures the sealing performance during cleaning, and the support legs 14 are used to support the entire device.

[0025] Example 2: As Figures 1-4 shown, a solenoid valve 44 is provided at a position near the top of the outer surface of the hollow shell 41, and the bottom of the cleaning tank 1 is inclined from both sides to the middle.

[0026] The effect achieved by the entire Embodiment 2 is that the rapid response ability of the solenoid valve 44 enables the cleaning water to be quickly and evenly sprayed onto every corner inside the cleaning tank 1. Combined with the forward and reverse rotation of the stirring system, it accelerates the dissolution and removal of the residues on the surface of the sample, significantly improving the cleaning efficiency. The inclined bottom design also helps to reduce the direct impact of the water flow on the bottom of the tank during the cleaning process, extending the service life of the cleaning tank 1.

[0027] Working principle: When using this device, the food sample is put into the cleaning tank 1 through the feeding hopper 11, and then distilled water is injected into the cleaning tank 1 through the water injection pipe 12. During the water injection process, the water level gauge 5 continuously monitors the water level change. When the water level reaches the preset position, the water level gauge 5 transmits the detected signal to the controller 53. After receiving the signal, the controller 53 immediately closes the first valve 13 to stop the injection of distilled water and prevent the water level from being too high and affecting subsequent operations. When it is necessary to clean the sample, the cleaning program is started through the controller 53 to drive the driving motor 22 on the mounting rack 21 to operate. After the driving motor 22 is decelerated by the speed reducer 23, it drives the first gear 3 to rotate. The first gear 3 is fixedly connected to the stirring rod 31, so the stirring rod 31 and multiple groups of stirring blades 32 rotate accordingly. While the stirring blades 32 are rotating, the first valve 13 on the water injection pipe 12 is opened to inject cleaning water into the hollow shell 41 at the bottom of the second gear 4. The cleaning water enters multiple groups of hollow rods 42 through the hollow shell 41 and is sprayed evenly over the entire cleaning area by the nozzles 43. Since the first gear 3 and the second gear 4 are in a meshing connection state, when the first gear 3 rotates forward driven by the driving motor 22, the second gear 4 will rotate in reverse. The water flow and stirring action generated by this forward and reverse rotation in different directions can stir the food sample more evenly, making the residual sulfur dioxide on its surface dissolve more fully in the water and improving the cleaning effect. After the cleaning is completed, the second valve 52 is opened through the controller 53. Under the control of the second valve 52, the cleaning water will pass through the filter screen 16 for filtration, and after removing large particle impurities, it will flow into the detection tank 51. Then, the sulfur dioxide detection instrument in the detection tank 51 is used to detect the food sample. The detection process may involve chemical reactions, photoelectric colorimetry or other advanced analysis techniques, depending on the type and principle of the detection instrument. After the detection is completed, the controller 53 will record and display the detection results for the operator to analyze and evaluate. This device effectively removes the residual sulfur dioxide on the surface of the food sample through an automated cleaning and stirring system, ensuring the reliability of the detection results. The unique forward and reverse rotation stirring design enhances the cleaning effect, making the sample cleaning more thorough. Moreover, the rapid response ability of the solenoid valve 44 enables the cleaning water to be quickly and evenly sprayed onto every corner inside the cleaning tank 1. Combined with the forward and reverse rotation of the stirring system, it accelerates the dissolution and removal of the residues on the surface of the sample, significantly improving the cleaning efficiency. The inclined bottom design also helps to reduce the direct impact of the water flow on the bottom of the tank during the cleaning process, extending the service life of the cleaning tank 1.

Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields.
