Description

Technical Field

[0001] This utility model relates to the technical field of wastewater detection equipment, and in particular to a fluorescent signal recognition device. Background Technology

[0002] When detecting the concentration of organic matter in wastewater, fluorescence screening is a common method. Fluorescent wastewater screening uses fluorescent probes to detect the concentration of organic matter in water. It can quickly and accurately determine the distribution of organic matter in water, making it a highly effective environmental monitoring tool. A fluorescent probe is a special molecule capable of emitting and exciting fluorescent signals. The intensity and characteristics of the fluorescence signal can be used to detect the concentration and type of organic matter in the water. In practice, the collected water sample is added to the fluorescent probe, stirred thoroughly, and then analyzed using a fluorescence analyzer. The fluorescence analyzer measures the fluorescence intensity and characteristics of the fluorescent probe in the water sample, thus determining the concentration and type of organic matter. However, when there are many samples to be tested, manual stirring of each wastewater sample with the fluorescent probe is required, resulting in low efficiency. Utility Model Content

[0005] The stirring assembly includes a mounting plate, with multiple stirring rods rotatably connected to the center of the mounting plate, corresponding to the number and position of the test tubes. Two sets of adjacent stirring rods are driven by a pulley assembly. Multiple uniformly distributed stirring blades are fixedly connected to the outer circumference of the stirring rods. Two motors are fixedly installed on one side of the upper surface of the mounting plate, and the output ends of the two motors pass through the mounting plate and are fixedly connected to the two stirring rods below.

[0006] Specifically, the lower surface of the mounting plate is fixedly connected with multiple sealing caps corresponding to the number and position of the stirring rods, and the stirring rods pass through the sealing caps and are rotatably connected to them.

[0007] Specifically, the mounting plate is provided with lifting components on both sides for controlling the lifting and lowering of the mounting plate. The lifting components include two support rods symmetrically fixedly connected to the upper surface of the base plate. A threaded rod is rotatably connected to the inner cavity of one support rod. A first slider is threadedly connected to the outer circumference of the threaded rod. A lifting motor is fixedly installed on the upper surface of the one support rod.

[0019] To make the technical methods, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Example

[0021] like Figure 1-4 A fluorescence signal recognition device is shown, including a base plate 1, a test tube rack 2 is fixedly connected to the middle of the upper surface of the base plate 1, a plurality of test tubes 3 are movably inserted into the test tube rack 2, and a stirring assembly 4 is arranged above the test tubes 3;

[0022] The stirring assembly 4 includes a mounting plate 41. Multiple stirring rods 42, corresponding to the number and position of the test tubes 3, are rotatably connected to the middle of the mounting plate 41. Two sets of adjacent stirring rods 42 are driven by a pulley assembly 43. Multiple uniformly distributed stirring blades 44 are fixedly connected to the outer circumference of the stirring rods 42. Two motors 45 are fixedly installed on one side of the upper surface of the mounting plate 41. The output ends of the two motors 45 pass through the mounting plate 41 and are fixedly connected to the two stirring rods 42 below.

[0023] In use, the output of motor 45 drives the two stirring rods 42 on one side of mounting plate 41 to rotate. When the two stirring rods 42 on one side of mounting plate 41 rotate, they drive the adjacent stirring rods 42 to rotate through the pulley assembly 43. When the stirring rods 42 rotate, they drive the stirring blades 44 to rotate, thereby fully stirring and mixing the sewage and fluorescent probe in the test tube, which greatly improves the working efficiency.

[0024] Furthermore, a plurality of sealing caps 5 corresponding to the number and position of the stirring rods 42 are fixedly connected to the lower surface of the mounting plate 41. The stirring rods 42 pass through the sealing caps 5 and are rotatably connected to them, which facilitates the sealing of the test tube 3 and prevents the sewage and fluorescent probe inside the test tube 3 from spilling out when stirring.

[0025] Furthermore, lifting components 6 for controlling the raising and lowering of the mounting plate 41 are provided on both sides of the mounting plate 41. The lifting components 6 include two support rods 61 symmetrically fixedly connected to the upper surface of the base plate 1. A threaded rod 62 is rotatably connected to the inner cavity of one support rod 61. A first slider 63 is threadedly connected to the outer circumference of the threaded rod 62. A lifting motor 64 is fixedly installed on the upper surface of the one support rod 61. The output end of the lifting motor 64 passes through the upper surface of the support rod 61 and is fixedly connected to the threaded rod 62. A sliding rod 65 is fixedly installed in the inner cavity of the other support rod 61. A second slider 66 is slidably connected to the outer circumference of the sliding rod 65. In use, the output end of the lifting motor 64 drives the threaded rod 62 to rotate. The threaded rod 62 drives the first slider 63 to move. When the first slider 63 moves, it drives the mounting plate 41 and the second slider 66 to move, which facilitates the movement of the stirring component 4 into the test tube 3.

[0026] Furthermore, the first slider 63 and the second slider 66 are fixedly connected to both sides of the mounting plate 41, respectively, to ensure the stability of the mounting plate 41 during movement.

[0027] Furthermore, the four parts on the lower surface of the mounting plate 41 are all fixedly installed with support feet 7, which facilitates the stability of the mounting plate 41 during operation.

[0028] Furthermore, the sealing cap 5 is adapted to the test tube 3, further ensuring the airtightness of the test tube 3.

[0029] Working principle

[0030] In use, the staff adds wastewater and fluorescent reagent into test tube 3, then places test tube 3 stably in test tube rack 2, and starts lifting motor 64. The output end of lifting motor 64 drives threaded rod 62 to rotate, threaded rod 62 drives first slider 63 to move, and the movement of first slider 63 drives mounting plate 41 and second slider 66 to move until the sealing cap 5 on the lower surface of mounting plate 41 abuts against test tube 3. Then, motor 45 is started, and the output end of motor 45 drives two stirring rods 42 on one side of mounting plate 41 to rotate. When the two stirring rods 42 on one side of mounting plate 41 rotate, they drive adjacent stirring rods 42 to rotate through pulley assembly 43. When stirring rods 42 rotate, they drive stirring blades 44 to rotate, thereby fully stirring and mixing the wastewater and fluorescent probe in the test tube, greatly improving work efficiency.
