Description

Technical Field

[0001] The utility model belongs to the technical field of colorimetric tube cleaning, and in particular relates to a colorimetric tube cleaning device. Background Art

[0002] Colorimetric tubes are the primary instruments used for visual colorimetric analysis in chemical experiments. They can be used to roughly measure solution concentrations. During colorimetric analysis, a colorimetric tube containing the test solution is placed in front of a piece of white paper with the same illumination level for comparison, and the color difference is observed with the naked eye. When colorimetric tubes are used in different experiments, cleaning them can prevent the impact of different solutions on the experimental results. In addition, cleaning is also to ensure that the transparency of the colorimetric tubes is not affected, thereby ensuring the reliability of the experimental results. The usual process for cleaning colorimetric tubes in the laboratory is to pour the waste liquid in the colorimetric tubes into a waste liquid bucket one by one, and then rinse the colorimetric tubes one by one with cleaning fluid. This waste liquid treatment and cleaning method is time-consuming and labor-intensive, and inefficient for cleaning a large number of colorimetric tubes in the laboratory.

[0003] The Chinese utility model patent No. 202221997798.8 discloses a rapid cleaning device for laboratory colorimetric tubes, which solves the problem of how to clean colorimetric tubes in batches. However, the following problems still exist: (1) During the colorimetric tube cleaning process, manual spraying of cleaning liquid is still required, and after cleaning is completed, the cleaning liquid in the colorimetric tubes needs to be manually poured out one by one, which is time-consuming and labor-intensive; (2) Only the inner wall of the colorimetric tube can be cleaned, and the outer wall cannot be cleaned at the same time, resulting in incomplete cleaning of the colorimetric tube; (3) During the cleaning process, the cleaning liquid in the colorimetric tube is not flowing, and waste liquid and cleaning agent are easily left on the inner wall of the colorimetric tube. Utility Model Content

[0004] The utility model aims to provide a colorimetric tube cleaning device to solve the technical problems existing in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] Preferably, the second mounting frame is further provided with a plurality of parallel cleaning sleeves, each of which is coaxially arranged with a corresponding cleaning roller, and bristles are evenly arranged on the inner wall of the cleaning sleeve, so that the outer wall of the colorimetric tube can be cleaned by the cleaning sleeve.

[0008] Preferably, the cleaning drive mechanism includes a gearbox, a drive motor, a driving gear and multiple driven gears. The driving gear and the driven gear are rotatably connected in the gearbox and mesh with each other. The drive motor is connected to the driving gear. The output shafts of the driving gear and the driven gear are respectively connected to the clamping parts. The cleaning drive mechanism can realize multi-output shaft output power.

[0009] Preferably, the clamping member includes a clamping sleeve, and a rubber pad is provided in the clamping sleeve. When the tail of the colorimetric tube is inserted into the clamping sleeve, the rubber pad can increase the friction between the colorimetric tube and the inner wall of the clamping sleeve, thereby effectively increasing the clamping force of the clamping sleeve.

[0010] Preferably, sliders are provided at both ends of the slide, and the sliders are slidably connected to the slide rails above the water receiving trough. The slide is connected to the slide rails through the sliders, thereby ensuring the stability of the slide movement.

[0011] The slide is connected to a travel drive mechanism, which includes a manual crank, a screw rod and a drive block. Both ends of the screw rod are rotatably connected to the water tank. The drive block is fixed to the bottom of the slide and is threadedly connected to the screw rod. The manual crank is connected to one end of the screw rod. The slide is driven to move by the travel drive mechanism, which improves the stability of the slide movement and saves more effort.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] (1) When cleaning the colorimetric tube of the present invention, a cleaning roller is inserted into the colorimetric tube by moving the slide. The cleaning roller sprays cleaning liquid into the colorimetric tube through the liquid inlet channel and the liquid outlet. The colorimetric tube rotates under the drive of the cleaning drive mechanism, thereby achieving cleaning of the inner wall. Since the colorimetric tube is placed horizontally during the cleaning process, the cleaning liquid can automatically flow out of the colorimetric tube under the action of gravity after washing, and there is no need to manually pour the cleaning liquid, which reduces the workload and improves the cleaning efficiency. Moreover, since the cleaning liquid is flowing, it can take away the cleaned pollutants, and the colorimetric tube is cleaned more thoroughly.

[0014] (2) The utility model provides a coaxial cleaning sleeve on the outside of the cleaning roller. During the cleaning process, the colorimetric tube is inserted between the cleaning roller and the cleaning sleeve. When the colorimetric tube rotates, the cleaning roller and the cleaning sleeve can clean the inner and outer walls of the colorimetric tube at the same time, so that the colorimetric tube is cleaned more thoroughly.

The cleaning rollers 7 are provided with a liquid inlet channel 19 and multiple liquid outlet holes 20 connected to the liquid inlet channel 19. The liquid inlet channel 19 is used to transport cleaning liquid, and the liquid outlet holes 20 are used to discharge cleaning liquid. The liquid inlet 10 of the liquid inlet channel 19 is connected to the cleaning liquid supply mechanism through an infusion tube. The cleaning liquid supply mechanism is used to transport cleaning liquid into the liquid inlet channel 19. It is a well-known technology in the field and will not be repeated here.

[0022] like Figure 1 、 Figure 2As shown, the second mounting frame 9 is further provided with a plurality of parallel cleaning sleeves 8, each cleaning sleeve 8 is coaxially arranged with the corresponding cleaning roller 7, and bristles 21 are evenly arranged on the inner wall of the cleaning sleeve 8, and the outer wall of the colorimetric tube 6 can be cleaned by the cleaning sleeve 8.

[0023] like Figure 2 As shown, the cleaning drive mechanism includes a gear box 3, a drive motor 4, a driving gear 17 and a plurality of driven gears 18. The driving gear 17 and the driven gear 18 are rotatably connected in the gear box 3 and mesh with each other. The drive motor 4 is connected to the driving gear 17. The output shafts of the driving gear 17 and the driven gear 18 are respectively connected to the clamping member 5. When working, the drive motor 4 outputs power to the driving gear 17, and then the driving gear 17 drives the multiple driven gears 18 that mesh with each other to rotate, thereby realizing multi-output shaft output power.

[0024] like Figure 4 As shown, the clamping member 5 includes a clamping sleeve 22, and a rubber pad 23 is provided in the clamping sleeve 22. When the tail of the colorimetric tube 6 is inserted into the clamping sleeve 22, the rubber pad 23 can increase the friction between the colorimetric tube 6 and the inner wall of the clamping sleeve 22, thereby effectively increasing the clamping force of the clamping sleeve 22.

[0025] like Figure 1 As shown, sliders 15 are provided at both ends of the slide 11, and the sliders 15 are slidably connected to the slide rails 16 above the water receiving trough 1. The slide 11 is connected to the slide rails 16 through the sliders 15, which ensures the stability of the movement of the slide 11.

During the movement, the colorimetric tube 6 is inserted as a whole between the cleaning sleeve 8 and the cleaning roller 7 at the corresponding position until the colorimetric tube 6 is completely immersed in the cleaning sleeve 8. At this time, the cleaning liquid supply mechanism is turned on, and the cleaning liquid supply mechanism delivers cleaning liquid to the liquid inlet channel 19 in the cleaning roller 7. The cleaning liquid in the liquid inlet channel 19 enters the colorimetric tube 6 through the liquid outlet hole 20. , and flows into the cleaning sleeve 8 through the tube mouth of the colorimetric tube 6. At the same time, the cleaning drive mechanism is turned on, and the cleaning drive mechanism drives the clamping member 5 and the colorimetric tube 6 to rotate. The bristles 21 on the cleaning sleeve 8 and the cleaning roller 7 respectively contact and rub with the outer wall and inner wall of the colorimetric tube 6, thereby achieving the simultaneous cleaning of the outer wall and inner wall of the colorimetric tube 6. The cleaned pollutants are mixed with the cleaning liquid and flow out through the opening of the cleaning sleeve 8 and fall into the water receiving tank 1 below. After cleaning, the cleaning liquid supply mechanism and the cleaning drive mechanism are closed, and the slide 11 is driven to move in the opposite direction to completely separate the colorimetric tube 6 from the cleaning sleeve 8 and the cleaning roller 7. Then the colorimetric tube 6 is removed from the clamping member 5, dried and stored.
