DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-4 , this embodiment provides a technical solution: A selenium-enriched malt powder detector includes a detection housing 1 and a positioning mechanism 2;

[0022] Detection housing 1: A detection container 5 is placed inside it, providing space for storing the detection sample of selenium-enriched malt powder. A magnetic stirring plate 4 is placed on the bottom wall of the detection container 5. By rotating the magnetic stirring plate 4, the solution in the detection container 5 is automatically stirred, making the selenium-enriched malt powder solution more uniform and improving the accuracy of the detection results. A single-chip microcomputer 7 is provided on the surface of the detection housing 1. The input end of the single-chip microcomputer 7 is electrically connected to an external power supply to control the start and stop of the overall device. A light source 10 and a monochromator 11 are respectively provided at the right end inside the detection housing 1. A detector 12 is provided at the left end inside the detection housing 1. The output end of the detector 12 is electrically connected to the input end of the single-chip microcomputer 7, and the input end of the light source 10 is electrically connected to the output end of the single-chip microcomputer 7. When the light source 10 is started, the light emitted by the light source 10 is decomposed into monochromatic light beams by the monochromator 11. The light beams pass through the light-transmitting surface of the detection container 5 and pass through the selenium-enriched malt powder solution. The specified substance in the selenium-enriched malt powder solution will absorb the light. Finally, the detector 12 receives the optical signal and converts it into an electrical signal to measure the intensity of the light, and detects the content of the substance in the selenium-enriched malt powder solution through the change in intensity;

[0023] Positioning mechanism 2: It includes an inner shell 21, a placement groove 22, a top plate 23, a top compression spring 25, and a limit cover plate 27. The inner shell 21 is arranged in the groove in the middle of the detection shell 1. The upper surface of the inner shell 21 is provided with a placement groove 22. A top plate 23 is vertically slidably connected inside the placement groove 22. Top compression springs 25 are respectively arranged between the bottom wall of the placement groove 22 and the top plate 23. A magnetic attraction turntable 3 is rotatably connected to the middle of the top plate 23. When the magnetic attraction turntable 3 rotates, a magnetic attraction force is applied to the magnetic attraction stirring plate 4 by the magnetic attraction turntable 3, driving the magnetic attraction stirring plate 4 to rotate. The limit cover plate 27 is rotatably connected to the upper end of the groove in the middle of the detection shell 1 through a rotating shaft. The limit cover plate 27 is cooperatively installed with the detection container 5. The detection container 5 is placed in the placement groove 22. The limit cover plate 27 is rotated to close the detection space through the limit cover plate 27. The limit cover plate 27 applies a downward pressure to the detection container 5, overcoming the elastic force of the top compression spring 25, causing the top plate 23 to move downward in the placement groove 22. Under the elastic force of the top compression spring 25, the detection container 5 is clamped and limited up and down, quickly determining the position of the detection container 5. The positioning mechanism 2 further includes guide posts 24. The guide posts 24 are respectively arranged on the lower surface of the top plate 23. The guide posts 24 are vertically slidably connected to the guide holes in the bottom wall of the placement groove 22, providing a guiding function for the movement of the top plate 23. The positioning mechanism 2 further includes a rubber pad 26. The rubber pad 26 is arranged on the lower surface of the limit cover plate 27 to prevent the force applied by the limit cover plate 27 to the detection container 5 from being too large. Electric push rods 8 are respectively arranged on the top wall of the inner shell 21. Clamping plates 9 are arranged at the ends of the telescopic ends of the electric push rods 8. The two clamping plates 9 are symmetric left and right. The clamping plates 9 are cooperatively installed with the light-transmitting surface of the detection container 5. The input ends of the electric push rods 8 are electrically connected to the output end of the single-chip microcomputer 7. When the electric push rods 8 are started, the telescopic ends of the electric push rods 8 drive the clamping plates 9 to move. The two clamping plates 9 move relatively to clamp the detection container 5 left and right, making the light-transmitting surface of the detection container 5 perpendicular to the light beam direction. A motor 6 is arranged in the installation groove in the middle of the top plate 23. The upper end of the output shaft of the motor 6 is provided with a magnetic attraction turntable 3. The input end of the motor 6 is electrically connected to the output end of the single-chip microcomputer 7, providing power for the rotation of the magnetic attraction turntable 3.

[0024] The working principle of a selenium-rich malt powder detector provided by the present utility model is as follows: When detecting selenium-rich malt powder, the selenium-rich malt powder is made into a solution and poured into the interior of the detection container 5. The detection container 5 is placed in the placement groove 22. The limit cover plate 27 is rotated to close the detection space through the limit cover plate 27. The limit cover plate 27 applies a downward pressure on the detection container 5 to overcome the elastic force of the top pressure spring 25, causing the top plate 23 to move downward in the placement groove 22. Under the action of the elastic force of the top pressure spring 25, the detection container 5 is clamped and limited up and down. Then, the single-chip microcomputer 7 is used to start the electric push rod 8. The telescopic end of the electric push rod 8 drives the clamping plate 9 to move. The two clamping plates 9 move relatively to clamp the detection container 5 left and right, making the light-transmitting surface of the detection container 5 perpendicular to the light beam direction, completing the rapid positioning of the detection container 5. After the positioning is completed, the motor 6 is started. The output shaft of the motor 6 drives the magnetic adsorption turntable 3 to rotate. The magnetic adsorption turntable 3 applies a magnetic adsorption force on the magnetic adsorption stirring plate 4 to drive the magnetic adsorption stirring plate 4 to rotate and stir the solution in the detection container 5, making the mixing of the selenium-rich malt powder more uniform. Before starting the detection, the magnetic adsorption stirring plate 4 stops stirring. The light source 10 is started. The light emitted by the light source 10 is decomposed into a monochromatic light beam by the monochromator 11. The light beam passes through the light-transmitting surface of the detection container 5 and passes through the selenium-rich malt powder solution. The specified substance in the selenium-rich malt powder solution will absorb the light. Finally, the detector 12 receives the light signal and converts it into an electrical signal to measure the intensity of the light, and detects the content of the substance in the selenium-rich malt powder solution through the change in intensity.

[0025] It should be noted that the single-chip microcomputer 7 disclosed in the above embodiments can be a single-chip microcomputer of the PIC16F1823-I / P model. The light source 10, the detector 12, the electric push rod 8, and the motor 6 can be freely configured according to the actual application scenario. The light source 10 can be a xenon lamp of the 190 - 840nm model. The detector 12 can be a spectrophotometer detector of the UV-1700 model. The electric push rod 8 can be an electric push rod of the LAM1 model. The motor 6 can be a motor of the RF300 model. The single-chip microcomputer 7 controls the operation of the light source 10, the detector 12, the electric push rod 8, and the motor 6 using common methods in the prior art.
