Technical Field

[0001] The utility model relates to the technical field of liquid detection, in particular to a stirring device for liquid detection. Background Technique

[0002] Liquid detection is an important analytical method widely used in fields such as scientific research, industrial production, and environmental monitoring. It is mainly used to determine the chemical components, pollutants, or other key parameters in liquid samples. These detections can involve multiple aspects, from water quality analysis to raw material inspection in pharmaceutical manufacturing, and applications in the field of food safety. When conducting liquid detection, molecules, ions, or suspended substances in the liquid often do not distribute evenly in a static state, which may lead to the inability to obtain a fully representative sample during sampling. In order to ensure the full mixing of various components in the liquid sample, people usually use a stirring device to mix it.

[0003] Therefore, the utility model patent with the publication number CN212549286U discloses a stirring device for liquid detection, including a stirring box. One side of the stirring box is hinged with a box door. The inner bottom of the stirring box is provided with a rotating motor. The output end of the rotating motor is fixedly connected with a first rotating shaft. The top of the first rotating shaft is fixedly installed with an operating platform for placing the liquid to be detected. A clamping mechanism is arranged on the operating platform. One side of the operating platform is provided with a stirring mechanism for stirring the liquid. The stirring mechanism includes a support plate fixedly installed on one side of the operating platform. A hydraulic telescopic rod is arranged above the support plate. The piston at the top of the hydraulic telescopic rod is fixedly installed with a cross bar. A stirring motor is arranged on one side of the cross bar close to the operating platform. The output end of the stirring motor is fixedly connected with a second rotating shaft. A plurality of stirring fan blades are evenly arranged on the second rotating shaft, which can fully stir the liquid and prevent the substances in the liquid from being oxidized, and has strong practicability.

[0004] However, the stirring mechanism of this patent is not convenient to disassemble and clean after use, and it is rather troublesome to clean the stirring mechanism after use. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a stirring device for liquid detection in view of the above-mentioned deficiencies of the prior art. It can be disassembled, thus facilitating cleaning, and can effectively avoid affecting subsequent use due to inadequate cleaning.

[0006] The technical solution adopted by the utility model is a stirring device for liquid detection, including a bottom plate. A fixed column is fixedly installed on the top of the bottom plate.

[0021] Figure 1 Schematically shown is a stirring device for liquid detection of the present utility model, which includes a bottom plate 1. A fixed column 12 is fixedly installed on the top of the bottom plate 1. The fixed column 12 is of a hollow structure. A movable column 13 is slidably installed in the fixed column 12. A detachable lifting device 2 is provided in the movable column 13 and the fixed column 12. A cross bar 14 integrally formed with the movable column 13 is provided at the top of the movable column 13. A stirring device 3 is provided in the cross bar 14. An installation groove 15 is formed at the bottom of the bottom plate 1 below the stirring device 3. A fixing device 4 is provided in the installation groove 15. Installation blocks 5 integrally formed with the bottom plate 1 are provided at the four corners of the bottom plate 1. Installation holes 51 are formed in the middle of the installation blocks 5. The device can be fixedly installed by setting fixing tools such as bolts in the installation holes 51. Scale lines 6 are provided on one side surface of the movable column 13. The scale lines 6 facilitate the user to observe the moving height of the movable column 13, thereby facilitating fine adjustment.

[0022] Such as Figure 2 And Figure 3The lifting device 2 shown includes a threaded hole 21 which is opened in the movable column 13. A threaded rod 22 is threadedly connected in the threaded hole 21. The bottom end of the threaded rod 22 is rotatably connected to the fixed column 12. A worm gear 23 is fixedly installed on the outer wall of the bottom end of the threaded rod 22. A worm 24 is rotatably connected to one side of the worm gear 23. One end of the worm 24 passes through the fixed column 12 and is fixedly connected to a first motor 25. The bottom end of the first motor 25 is fixedly connected to the top of the bottom plate 1. The stirring device 3 includes a second motor 31. A support column 32 is fixedly installed at the bottom of the second motor 31. The bottom end of the support column 32 is fixedly connected to the top of the cross bar 14. A transmission column 33 is fixedly connected to the rotor part of the second motor 31. The transmission column 33 passes through the cross bar 14 and is fixedly connected to a stirring block 34. A magnetic coupling 7 is fixedly installed at the connection between the rotor of the second motor 31 and the transmission column 33. The transmission column 33 is fixedly connected to the rotor of the second motor 31 through the magnetic coupling 7. The magnetic coupling 7 can adopt models such as HSFO8. This model can disconnect when the load is too large, thereby protecting the second motor 31.

[0023] In a specific implementation, only need to start the first motor 25. The rotation of the first motor 25 will drive the rotation of the worm 24. The rotation of the worm 24 will drive the rotation of the worm gear 23. The rotation of the worm gear 23 will drive the threaded rod 22 to rotate in the threaded hole 21, thereby moving the movable column 13. The movement of the movable column 13 will drive the movement of the cross bar 14, thereby driving the movement of the stirring device 3. By continuously rotating the first motor 25, the threaded rod 22 and the threaded hole 21 will lose their cooperation. At this time, the movable column 13 can be removed, and then the stirring device 3 can be removed, which is convenient for cleaning. And to install the movable column 13, just align the threaded hole 21 with the threaded rod 22, and then start the first motor 25 to reverse, and the threaded hole 21 and the threaded rod 22 can be re-mated. When wanting to stir the liquid to be detected, only need to adjust the stirring block 34 to a suitable position through the lifting device 2 and then start the second motor 31. The rotation of the second motor 31 will drive the rotation of the transmission column 33, and the rotation of the transmission column 33 will drive the rotation of the stirring block 34, thereby stirring the liquid.

[0024] As Figure 2 and Figure 4 The fixing device 4 shown includes a grip 41. A cylinder 42 is fixedly connected to one side of the grip 41. One end of the cylinder 42 passes through the bottom plate 1 and is rotatably installed in the installation groove 15. A left-handed thread 43 is opened at one end of the cylinder 42 located in the installation groove 15, and a right-handed thread 44 is opened at the other end. Clamping blocks 45 are threadedly connected to the surfaces of both the left-handed thread 43 and the right-handed thread 44.

[0025] In a specific implementation, simply place the container filled with the liquid to be stirred on the bottom plate 1, and then hold the handle 41 and rotate it. The rotation of the handle 41 will drive the rotation of the cylinder 42, which in turn drives the rotation of the left thread 43 and the right thread 44. The rotation of the left thread 43 and the right thread 44 will drive the clamping blocks 45 threadedly connected to their surfaces to approach each other, thereby clamping the container to complete the fixation. To release the fixation, simply reverse-rotate the handle 41.
