Description

Technical Field

[0001] This utility model relates to the field of mixing equipment, specifically a colorimetric tube mixing device for water quality analysis sample preparation. Background Technology

[0002] Colorimetric tubes are the main instruments used in chemical experiments for visual colorimetric analysis. They can be used to roughly measure solution concentration. For solutions that require time or stirring to fully develop color, the colorimetric tube should be gently shaken to mix the solution thoroughly. During colorimetric analysis, the colorimetric tube containing the test solution and a colorimetric tube containing a standard solution are placed in front of white paper under the same lighting conditions for comparison, and the color difference is observed with the naked eye.

[0003] Existing colorimetric tubes typically require manual stirring by the operator, who holds the top of the tube firmly and shakes it. This is time-consuming, labor-intensive, and inefficient. Furthermore, some of the solutions being compared are toxic, posing a risk to manual stirring. Therefore, those skilled in the art have provided a colorimetric tube stirring device for water quality analysis sample preparation to address the problems mentioned in the background section.

[0011] As a further improvement of this utility model: a universal joint is vertically provided on the outer side of the top of the base, the root of the universal joint is connected to the base by a thread, and an LED light panel is provided on the top of the universal joint.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this utility model, a top ball seat is provided on the top of the bottom ball seat, and a ball sleeve is rotatably connected between the bottom ball seat and the top ball seat. A colorimetric tube is slidably connected inside the ball sleeve, and the tail end of the colorimetric tube is slidably connected to the guide ring.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-6 In this embodiment of the present invention, a colorimetric tube stirring device for water quality analysis sample preparation includes a base 4, a ball sleeve 8, and a turntable 5. A bottom ball seat 1 is provided above the base 4, and three support rods 3 are obliquely and evenly welded between the bottom ball seat 1 and the base 4. A top ball seat 2 is provided on the top of the bottom ball seat 1, and a ball sleeve 8 is rotatably connected between the bottom ball seat 1 and the top ball seat 2. Limiting platforms are provided at the upper and lower ends of the ball sleeve 8. A stirring motor 13 is fixedly connected to the bottom center of the base 4 by bolts, and the output shaft of the stirring motor 13 is fixedly connected to the turntable 5. The turntable 5 is offset near the center. A connecting rod 6 is vertically welded at the core position. A guide ring 7 is rotatably connected to the top of the connecting rod 6. The rotation angle of the connecting rod 6 and the guide ring 7 is locked by an internal hex bolt, which facilitates the adjustment of the angle of the guide ring 7, thereby changing the stirring intensity. A colorimetric tube 9 is slidably connected inside the ball sleeve 8. The tail end of the colorimetric tube 9 is slidably connected to the guide ring 7. The colorimetric tube 9 is easy to install and remove. The guide ring 7 drives the tail end of the colorimetric tube 9 to rotate, which simulates manual shaking for stirring. The stirring speed is uniform and the stirring efficiency is high. When stirring hazardous solutions, manual operation is avoided, making it safer.

[0024] The bottom ball seat 1 has an external thread 14 on its top outer side and an internal thread 17 on its bottom inner side. The bottom ball seat 1 and the top ball seat 2 are connected by threads, which makes disassembly convenient and facilitates maintenance of the ball sleeve 8.

[0025] The outer side of the top ball seat 2 is provided with anti-slip texture 16, which facilitates the installation and removal of the top ball seat 2 and makes it easy to use;

[0026] Among them, the turntable 5 has an inverted bowl-shaped structure to prevent debris from entering between the turntable 5 and the stirring motor 13 and affecting the rotational stability of the turntable 5. The center of the output shaft of the stirring motor 13 is provided with a connecting threaded hole 15, and hexagonal bolts are used to connect the turntable 5 and the connecting threaded hole 15.

[0027] Among them, a bushing 12 is provided between the ball sleeve 8 and the colorimetric tube 9. The bushing 12 is bonded to the ball sleeve 8 and slidably connected to the colorimetric tube 9. Multiple clamping slots 18 are evenly distributed on the inner side of the bushing 12 to increase the clamping force of the colorimetric tube 9, prevent the colorimetric tube 9 from rotating, and improve the stirring effect.

[0028] A universal joint 10 is vertically installed on the outer side of the top of the base 4. The root of the universal joint 10 is connected to the base 4 by a thread. An LED light panel 11 is installed on the top of the universal joint 10 to provide supplementary lighting when the lighting conditions are poor, and to provide the same light source for comparison, so as to facilitate observation by the color tube 9.

[0029] The working principle of this utility model is as follows: First, install the colorimetric tube 9, ensuring the sealing plug is properly installed. Loosen the internal hex bolts of the locking guide ring 7, release the angle adjustment of the guide ring 7, and insert the colorimetric tube 9 into the ball sleeve 8, allowing the colorimetric tube 9 to slide and connect with the bushing 12. The top edge of the colorimetric tube 9 should be in contact with the top of the ball sleeve 8, and the bottom of the colorimetric tube 9 should be inserted into the guide ring 7. After adjusting the stirring angle of the colorimetric tube 9, tighten the angle adjustment of the guide ring 7 again. Start the power supply to make the stirring motor 13 rotate, thereby driving the turntable 5 to rotate. The rotating mechanism, driven by the turntable 5, rotates the guide ring 7 and the tail of the colorimetric tube 9 to simulate the manual shaking and stirring process. During this process, the ball sleeve 8 is rotatably connected to the top ball seat 2 and the bottom ball seat 1, ensuring stable stirring speed and high stirring efficiency. This avoids direct manual stirring and makes it safer to use. When observing after stirring, if the ambient light is insufficient, the LED light panel 11 is activated, and the universal joint 10 is adjusted to align the LED light panel 11 with the colorimetric tube 9. White paper is placed at the colorimetric tube 9 for auxiliary observation, improving observation accuracy and making it convenient to use.

[0030] 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.
