Description

Technical Field

[0001] The present invention belongs to the intersection of medical agricultural water resources and food detection, and specifically relates to a disinfectant concentration and residue detection device. Background Art

[0002] Disinfectants are chemical agents primarily designed to kill microorganisms. They are designed to kill pathogenic microorganisms on transmission media and render them harmless. Their active ingredients primarily exert their effects through oxidation, disruption of microbial protein structure, and metabolic disruption. They are widely used in the medical, sanitation, pesticide residue, food, and industrial sectors. The bactericidal ability of disinfectants is positively correlated with their concentration. Insufficient chlorine concentrations prevent effective destruction of microbial protein structures or metabolic systems, significantly reducing the kill rate against viruses and bacteria. This can lead to pathogen residues and increase the risk of infection. 75% alcohol is the optimal bactericidal concentration. If the concentration is below 60%, the alcohol's ability to penetrate microbial cell membranes is weakened, protein denaturation is incomplete, and the bactericidal effect is significantly reduced. Therefore, disinfectants require concentration testing during production. Disinfectant concentration and residue detection devices are specialized equipment used to rapidly determine the concentration of disinfectant active ingredients and the amount of residue remaining on surfaces.

[0003] Existing disinfectants contain emulsifiers to enhance their cleaning or sterilization effects. These ingredients can easily reduce surface tension in the solution. When the disinfectant sample or the residual sample to be tested is unstable, air can easily mix in and form bubbles. At the same time, the disinfectant may dissolve gases in the air during storage. When the temperature rises during testing, the solubility of the dissolved gas decreases, and it often precipitates in the form of bubbles. When these bubbles are suspended in the solution, they form local optically uneven areas, affecting the stability of light passing through the sample, resulting in poor repeatability of the test data and poor accuracy of the concentration calculation results. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the above-mentioned prior art and provide a disinfectant concentration and residue detection device.

[0005] The technical solution adopted to solve the above technical problems is: a disinfectant concentration and residue detection device, including a mounting base, the upper end of the mounting base is fixedly connected to a mounting box, the upper end of the mounting box is provided with a plug-in slot, the lower end of the mounting base is fixedly connected to a supporting foot, a test paper slot is provided in the mounting base, and limit slots are symmetrically provided on both sides of the test paper slot, and a test paper colorimetric component is arranged in the test paper slot; a photometry component is arranged in the plug-in slot, an automatic defoaming component is arranged below the photometry component, and a limit assembly is arranged at the lower end of the automatic defoaming component; the photometry component includes a light source system fixedly connected to the mounting box, a monochromator system is fixedly connected to the side of the plug-in slot close to the light source system, a colorimetric bottle is placed in the plug-in slot, and a sponge ring is fixedly connected to the upper end of the plug-in slot.

[0006] Through the above technical solution, the light source system emits composite light, which can obtain monochromatic light of a specific wavelength after being split by the monochromator system. The monochromatic light passes through the sample and is partially absorbed by the sample. The device can then analyze the concentration of the disinfectant. At the same time, when installing the colorimetric bottle into the socket, the sponge ring can clean the outside of the colorimetric bottle to increase the accuracy of the detection.

[0008] With the above technical solution, when the test paper colorimetric assembly needs to be replaced, the protrusion is pushed inward by hand, and the protrusion drives the mounting frame to slide into the test paper frame at the same time. The connecting rod pushes the connecting frame through the slider, and the connecting frame is subjected to pressure to press the moving block inward along the direction of the engaging groove through the engaging rod. The moving block is pushed to the side of the second return spring, and then the moving blocks on both sides simultaneously drive the limit blocks to move, so that they are retracted into the slide groove. At this time, the test paper colorimetric assembly loses the limit between it and the test paper slot, and the test paper colorimetric assembly can be quickly removed by pulling the handle slot under the test paper rack.

[0009] Furthermore, multiple sets of guide seats are fixedly installed in the color test frame, and the multiple sets of guide seats are respectively fixedly connected to a first return spring. The first return spring is fixedly connected to the mounting frame at one end away from the guide seat, and a second return spring is installed on the side of the moving block away from the slide groove.

[0012] Through the above technical solution, the inspector rotates the drive rod to provide initial power for the automatic defoaming component. The drive rod drives the rotating shaft to rotate, and the rotating shaft transmits power to the connecting seat. By shaking, the bubbles in the colorimetric bottle can float to the liquid surface and burst due to buoyancy and fluid dynamics, thereby improving the accuracy of disinfectant concentration detection.

[0013] Furthermore, a hairspring is installed on one end of the connecting seat close to the defoaming shaft, and a first mounting fork and a second mounting fork are respectively provided on the side of the hairspring away from the defoaming shaft.

[0018] Through the above technical solution, the positioning block is pulled outward, and the positioning block drives the positioning head on the sliding column to slide outward from the positioning hole, thereby releasing the lock of the positioning head on the driving rod, and rotating the positioning block so that the positioning block can be changed from a vertical state to a horizontal state, and placed on the fixing frame, so that the position of the positioning head can be fixed.

[0019] Furthermore, a display stand is fixedly installed on one side of the upper surface of the installation box, and a main control display screen is installed on the display stand.

Due to the high elasticity and high recovery performance of the hairspring itself, the hairspring can periodically drive the defoaming shaft on the connecting seat to repeatedly shake.

[0027] like Figures 1-6As shown, the automatic defoaming component 4 includes a driving box 40 rotatably connected to the installation box 14, and a rotating shaft 41 is rotatably connected in the driving box 40. A driving rod 42 is fixedly installed at the lower end of the rotating shaft 41, and a positioning hole 43 is symmetrically opened on the driving rod 42. The upper end of the rotating shaft 41 is fixedly connected to a connecting seat 44, and the upper end of the connecting seat 44 is fixedly connected to a defoaming shaft 45.

[0028] like Figures 1-9 As shown, a hairspring 412 is installed at one end of the connecting seat 44 close to the defoaming shaft 45, and a first mounting fork 47 and a second mounting fork 48 are respectively provided on the side of the hairspring 412 away from the defoaming shaft 45. The first mounting fork 47 and the second mounting fork 48 are both rotatably connected to the connecting seat 44. One end of the first mounting fork 47 is fixedly connected to a first moving pin 49, and one end of the second mounting fork 48 is fixedly connected to a second moving pin 411. The first moving pin 49 is slidably connected to the hairspring 412, and the end of the first mounting fork 47 away from the first moving pin 49 is fixedly connected to an extension rod 410. The connecting seat 44 rotates to drive the hairspring 412 to rotate and rewind. At this time, the driving rod 42 is released, and the hairspring 412 is subjected to torsion, and the hairspring 412 is repeatedly wound. During the opening and winding actions, the hairspring 412 itself has high elasticity and high recovery performance, so that the hairspring 412 can drive the defoaming shaft 45 on the connecting seat 44 to repeatedly shake the operation; the extension rod 410 is rotatably connected to the drive box 40, and a pointer 414 is fixedly connected to one end of the extension rod 410, and a scale seat 413 is fixedly connected to one side of the installation box 14. The pointer 414 is slidably connected to the scale seat 413, and the pointer 414 is rotated.

The inspector can adjust the elastic recovery force of the hairspring 412 according to the adjustment of the effective length of the hairspring 412, thereby controlling the swing speed of the placement seat 46.

[0029] like Figures 1-11The cam 53 is fixed to the locking cam 52 and the locking cam 53 is locked to the locking cam 52.

[0030] like Figure 1-Figure 3 As shown, a display frame 15 is fixedly installed on one side of the upper surface of the installation box 14, and a main control display screen 16 is installed on the display frame 15. The upper end of the installation box 14 is rotatably connected to a cover plate 17, and a fixing head 18 is fixedly connected to the inner side of the cover plate 17. A fixing groove 10 is opened at the upper end of the installation box 14, and the fixing head 18 can be plugged and fixed with the fixing groove 10. The cover plate 17 is rotated to close, and the fixing head 18 is stuck in the fixing groove 10, so that the colorimetric bottle 32 can be stored in the plug-in groove 19, and the detection personnel can control the device through the main control display screen 16.

[0031] The working principle of this embodiment is as follows: the disinfectant is poured into the cuvette 32, the cuvette 32 is placed on the placement seat 46 through the insertion slot 19, the cover 17 is rotated and closed, the fixing head 18 is engaged with the fixing slot 10, so that the cuvette 32 is placed in the insertion slot 19, the positioning block 55 is pulled outward, and the positioning block 55 drives the positioning head 53 on the slide column 52 to slide outward from the positioning hole 43, thereby releasing the locking position of the positioning head 53 on the drive rod 42, and the positioning block 55 is rotated so that the positioning block 55 can be changed from a vertical state to a horizontal state, and it is placed on the fixing frame 57, thereby fixing the position of the positioning head 53; The inspector rotates the drive rod 42 to provide initial power to the automatic defoaming assembly 4. The drive rod 42 drives the rotating shaft 41 to rotate. The rotating shaft 41 transmits power to the connecting seat 44. The connecting seat 44 rotates to drive the hairspring 412 to rotate and rewind. At this time, the drive rod 42 is released. The hairspring 412 is subjected to torsion and repeats the opening and rewinding action. The hairspring 412 has high elasticity and high recovery performance, so that the hairspring 412 can drive the defoaming shaft 45 on the connecting seat 44 to repeatedly shake. Further, the shaking causes the bubbles in the cuvette 32 to float to the liquid surface due to buoyancy and fluid dynamics and rupture. When the oscillation frequency of the placement seat 46 needs to be adjusted, the pointer 414 is rotated as needed. The pointer 414 drives the first movable pin 49 to slide along one end of the hairspring 412 via the extension rod 410. The inspector can adjust the elastic restoring force of the hairspring 412 by adjusting the effective length of the hairspring 412, thereby controlling the oscillation speed of the placement seat 46. The oscillation speed of the sample in the cuvette 32 is controlled at the critical bubble breaking speed by adjusting the effective length of the hairspring 412, thereby eliminating bubbles in the cuvette 32 without introducing new bubbles. When the test paper colorimetric assembly 2 needs to be replaced, the protrusion 23 is pushed inward by hand. The protrusion 23 drives the mounting frame 24 to slide into the test paper frame 20 at the same time. The connecting rod 25 pushes the connecting frame 29 through the slider 28. The connecting frame 29 is subjected to pressure and presses the moving block 211 inward along the direction of the locking groove 212 through the locking rod 210. The moving block 211 is pushed to the side of the second return spring 213, thereby causing the moving blocks 211 on both sides to simultaneously drive the limit blocks 215 to move and be retracted into the slide groove 214. At this time, the test paper colorimetric assembly 2 loses the limit between it and the test paper slot 11, and the test paper colorimetric assembly 2 can be quickly removed by pulling the handle slot 22 under the test paper frame 20.
