Description

Technical Field

[0001] This utility model relates to a preservative detection device, specifically an integrated quantitative detection device for food preservatives. Background Technology

[0002] Food preservatives are additives that prevent spoilage caused by microorganisms and extend the shelf life of food. Because they also prevent food poisoning caused by microbial growth, food preservatives are also known as antimicrobial agents. The main function of food preservatives is to inhibit the growth of microorganisms in food.

[0003] In actual production, quantitative testing of food preservatives is required. Currently, there are technologically mature testing instruments that allow for direct detection simply by placing the preservative solution into the instrument. However, before testing, personnel need to extract the preservative solution from the storage tank and then place it into the testing instrument. Currently, when extracting the solution, the differences in the properties of the preservative solution at different depths within the storage tank are often overlooked, leading to inaccurate test results. Utility Model Content

[0004] The purpose of this invention is to provide an integrated quantitative detection device for food preservatives, which can extract preservative liquid from different depths inside the storage tank multiple times and detect it separately, so that preservative liquid at different depths inside the storage tank can be detected, and more accurate data can be obtained by taking the average value.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an integrated food preservative quantitative detection device, comprising a storage tank and a detection mechanism mounted on the storage tank. The storage tank has an internally hollow cavity structure, and a first motor and a second motor located on one side of the first motor are fixed to the upper end face of the storage tank. A sliding groove communicating with the cavity is provided on the storage tank. An inner support shaft is fixedly connected to the output end of the first motor, and multiple sets of equally spaced blades are fixed on the inner support shaft. A screw is fixedly connected to the output end of the second motor. A slide block is threaded onto the screw, and the slide block fits against the inner wall of the slide groove, allowing the screw to move the slide block up and down within the slide groove during operation. A liquid collection pipe is fixed on the slide block and is located on the pump body. The end of the liquid collection pipe away from the storage tank is connected to an output pipe. The detection mechanism includes a detector located below the storage tank, which is equipped with multiple test tubes for containing preservative solution. The end of the output pipe away from the pump body extends above the multiple test tubes, and the output pipe is a flexible tube, which facilitates the guidance of the preservative solution in the output pipe to different test tubes.

[0006] Preferably, a reinforcing base is fixed at the bottom of the cavity of the storage tank, and the inner support shaft is rotatably connected to the reinforcing base, so that the bottom of the inner support shaft remains stable during operation.

[0007] Preferably, the screw is vertically arranged and rotatably connected to the storage tank, so that the second motor can drive the screw to operate stably when it is working.

[0008] Preferably, the two ends of the liquid taking pipe are distributed on both sides of the slide, and the end of the liquid taking pipe away from the pump body extends into the bottom of the storage tank cavity.

[0009] Preferably, the pump body is fixed to the outer wall of the storage tank, and a positioning plate is also fixed on the side of the storage tank where the pump body is located, and the output pipe slides through the positioning plate.

[0010] Preferably, four support legs are fixed to the lower end face of the storage tank, and a storage base is fixed between the four support legs, with the detector fixed on the storage base.

[0011] Preferably, an addition pipe is fixedly connected to the upper end face of the storage tank, and a discharge pipe is fixedly connected to the end of the storage tank away from the pump body; a valve is provided on the discharge pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model drives the second motor to run and drive the screw to rotate, so that the slide rises and falls to a specified height, and the liquid extraction tube rises and falls in the cavity of the storage tank. This allows the liquid extraction tube to extract the preservative liquid from different depths in the cavity of the storage tank multiple times and test them separately. This ensures that the preservative liquid at different depths in the storage tank can be detected, and more accurate data can be obtained by taking the average value. Attached Figure Description

[0021] Please see Figure 1 The present invention provides an embodiment of an integrated food preservative quantitative detection device, comprising a storage tank 1 and a detection mechanism disposed on the storage tank 1. The storage tank 1 has a hollow cavity structure, and a first motor 2 and a second motor 3 located on one side of the first motor 2 are fixed to the upper end face of the storage tank 1. Both the first motor 2 and the second motor 3 require external power supply. An addition pipe 18 is fixedly connected to the upper end face of the storage tank 1, and a discharge pipe 19 is fixedly connected to the end of the storage tank 1 away from the pump body 11. A valve is provided on the discharge pipe 19.

[0022] Please see Figure 2The testing mechanism includes a tester 16 located below the storage tank 1. The tester 16 is fixed on the base 15 to keep the structure of the tester 16 stable. The tester 16 is equipped with multiple test tubes 17 for containing preservative solution. The model of the tester 16 can be YT-FJ12.

[0023] Please see Figure 3 The output end of the first motor 2 is fixedly connected to an inner support shaft 5. Multiple sets of equally spaced blades 6 are fixed on the inner support shaft 5. A reinforcing base 7 is fixed at the bottom of the cavity of the storage tank 1. The inner support shaft 5 is rotatably connected to the reinforcing base 7, so that the bottom of the inner support shaft 5 remains stable during operation. A liquid extraction pipe 10 is provided on the storage tank 1. The liquid extraction pipe 10 is set on the pump body 11, and the end of the liquid extraction pipe 10 away from the storage tank 1 is connected to an output pipe 12. The end of the liquid extraction pipe 10 away from the pump body 11 extends into the cavity of the storage tank 1. At the bottom, the pump body 11 is fixed to the outer wall of the storage tank 1, and a positioning plate 13 is also fixed on the side of the storage tank 1 where the pump body 11 is located. The output pipe 12 slides through the positioning plate 13. Four support legs 14 are fixed on the lower end face of the storage tank 1, and a place seat 15 is fixed between the four support legs 14. The end of the output pipe 12 away from the pump body 11 extends above multiple test tubes 17. Both the liquid taking pipe 10 and the output pipe 12 are flexible tubes, which facilitates the guidance of the preservative liquid in the output pipe 12 into different test tubes 17.

[0024] Please see Figure 4 A groove 4 communicating with the cavity of the storage tank 1 is provided on the storage tank 1. A screw 8 is fixedly connected to the output end of the second motor 3. The screw 8 is set vertically and is rotatably connected to the storage tank 1, so that the second motor 3 can drive the screw 8 to run stably when it is working. A slide 9 is threaded on the screw 8. The slide 9 fits against the inner wall of the groove 4, so that the screw 8 can drive the slide 9 to rise and fall in the groove 4 when it is running. The liquid taking pipe 10 is fixed on the slide 9, and the two ends of the liquid taking pipe 10 are distributed on both sides of the slide 9.

[0025] Please refer to the following: Figures 1 to 4In this invention, the preservative material and experimental water are first added to the cavity of the storage tank 1 through the addition pipe 18. The first motor 2 is driven to operate, driving multiple sets of blades 6 to mix the preservative and water, making their components uniform. Then, the pump body 11 is driven to operate, and a certain amount of preservative liquid is drawn from a designated depth in the cavity of the storage tank 1 using the liquid extraction pipe 10 (the method of controlling the amount of preservative liquid is: the energizing time of the pump body 11 is constant each time it is extracted, thereby ensuring that the amount of preservative liquid extracted each time is basically the same, achieving quantitative extraction). The preservative liquid is sent to the first test tube 17 through the output pipe 12. Inside, the detector 16 performs the test; then, the second motor 3 is driven to run, which drives the screw 8 to rotate, causing the slide 9 to lift the liquid collection tube 10 (since the liquid collection tube 10 is a flexible tube, its lifting will not conflict with the pump body 11), changing the height of the liquid collection tube 10 in the cavity of the storage tank 1, so as to extract the preservative liquid from different depths in the cavity of the storage tank 1 and send it to the second test tube 17, so that the detector 16 can perform the test... Through the above method, the preservative liquid at different depths in the cavity of the storage tank 1 can be tested separately, and finally, by taking the average value, more accurate data can be obtained.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
