Description

Technical Field

[0001] This utility model relates to a multi-parameter water quality analyzer, belonging to the field of water quality analysis technology. Background Technology

[0002] Currently, water quality analysis typically uses digestion apparatus and optical colorimeters. The sample is first digested by using acid or alkali solutions and heating to destroy organic matter or reducing substances in the sample, so as to obtain the analyte in a form and concentration suitable for the analytical method and to separate it from interfering substances to the greatest extent possible. Then, optical detection is performed to obtain water quality data.

[0003] In traditional procedures, after samples are digested at high temperatures in a digester, the digestion tubes or colorimetric tubes need to be manually removed, cooled, and then transferred to an optical colorimeter for measurement. During manual transfer, sample spillage, loss due to adhesion to the instrument walls, or interference from environmental contaminants may occur, leading to inaccurate measurement results.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0005] This invention addresses the shortcomings of the prior art by providing a multi-parameter water quality analyzer that integrates heating digestion, cooling, and optical detection functions. It can automatically and continuously analyze multiple water samples, significantly improving detection efficiency.

[0006] To solve the above technical problems, the present invention adopts the following technical solution: The multi-parameter water quality analyzer includes a base capable of lifting and lowering. An inner shell and an outer shell are sequentially arranged around the base, with a heat-insulating cover installed on the top of both shells. An annular groove is located on the upper surface of the base, with annular heating belts installed on the inner and outer sides of the bottom of the groove. A light wave generator and a wavelength receiver are correspondingly positioned on the inner and outer sides of the groove near its top. A positioning groove is located at the center of the heat-insulating cover, used for placing a positioning plate. A downward-facing stepper motor is fixedly installed on the positioning plate, and a turntable is installed below the stepper motor.

[0007] Furthermore, the left and right sides of the base are respectively fixedly connected to the slider, and the slider is slidably set on the linear slide rail.

[0008] Furthermore, the linear guide rail is fixedly installed longitudinally on the inner wall of the inner housing.

[0009] Furthermore, an electric telescopic cylinder is installed between the bottom of the seat and the bottom of the inner shell.

[0010] Furthermore, the height of the annular heating band is less than the depth of the annular groove.

[0011] Furthermore, the light wave generator and wavelength receiver are positioned above the annular heating belt.

[0012] Furthermore, the turntable is provided with multiple circumferentially distributed mounting holes, each containing a cuvette.

[0013] Furthermore, the bottom end of the stepper motor output shaft is connected to the rotating shaft via a connector, and a turntable is fixed to the bottom end of the rotating shaft.

[0014] Furthermore, a cavity is formed between the inner shell and the outer shell, and a fan is fixedly installed in the cavity. The air outlet of the fan is connected to the outside of the outer shell.

[0015] Furthermore, ventilation holes are provided on the heat insulation cover and at the bottom of the inner shell.

[0016] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages: This invention, through the integrated design of a height-adjustable base and a rotating cuvette, enables the entire process of digestion, cooling, and detection to be completed automatically within a sealed unit. This avoids manual sample transfer, eliminates errors caused by manual transfer, greatly improves the accuracy and reproducibility of data, and significantly enhances detection efficiency.

[0021] like Figures 1-3As shown in the figure, this utility model provides a multi-parameter water quality analyzer, including a base 10 that can be raised and lowered, an inner shell 2 and an outer shell 3 arranged sequentially on the outside of the base 10, and a heat insulation cover 1 installed on the top of the inner shell 2 and the outer shell 3.

[0022] The left and right sides of the base 10 are fixedly connected to the sliders 15, which are slidably mounted on the linear slide rail 16. The linear slide rail 16 is fixedly mounted longitudinally on the inner wall of the inner housing 2. An electric telescopic cylinder 17 is installed between the bottom of the base 10 and the bottom of the inner housing 2. The electric telescopic cylinder 17 can drive the base 10 to move longitudinally along the linear slide rail 16.

[0023] The upper surface of the seat 10 is provided with an annular groove 11. Annular heating belts 12 are respectively installed on the inner and outer sides of the bottom of the annular groove 11. The height of the annular heating belts 12 is less than the depth of the annular groove 11. After the annular heating belts 12 are energized and heated, they can digest the sample.

[0024] Light wave generators 13 and wavelength receivers 14 are respectively arranged on the inner and outer sides of the annular groove 11 near its top position. The height of the light wave generators 13 and wavelength receivers 14 is above the annular heating belt 12.

[0025] A positioning groove 4 is provided at the center of the heat-insulating cover 1. The positioning groove 4 is used to place the positioning plate 6. A downward-facing stepper motor 5 is fixedly installed on the positioning plate 6. The bottom end of the output shaft of the stepper motor 5 is connected to the rotating shaft 7 through a connector. A turntable 8 is fixed to the bottom end of the rotating shaft 7. The turntable 8 has multiple circumferentially distributed mounting holes, and cuvettes 9 are installed in the mounting holes respectively. The stepper motor 5 can drive the turntable 8 to rotate, thereby realizing continuous detection of samples in different cuvettes 9.

[0026] The stepper motor 5, positioning plate 6, rotating shaft 7 and turntable 8 form a detachable whole, which makes it convenient for the cuvette 9 to be installed into the inner shell 2 or removed from the inner shell 2.

[0027] A cavity is formed between the inner shell 2 and the outer shell 3, which provides a certain degree of thermal insulation. A fan 18 is fixedly installed inside the cavity, and the air outlet of the fan 18 is connected to the outside of the outer shell 3. Ventilation holes are provided on the heat insulation cover 1 and the bottom of the inner shell 2. The fan 18 drives the airflow to achieve rapid heat dissipation of the annular heating strip 12.

[0028] The specific workflow of this utility model is as follows: The cuvette 9 containing the water sample is installed on the turntable 8, and then the entire rotating module is placed into the positioning slot 4. The base 10 is raised under the drive of the electric telescopic cylinder 17, so that the annular heating belt 12 is located on the inner and outer sides of the cuvette 9. The annular heating belt 12 is energized to heat the sample for timed and temperature-controlled digestion. After digestion, the base 10 is lowered, the annular heating belt 12 is separated from the cuvette, the cooling fan 18 is started to assist in cooling, and the light generator 13 and wavelength receiver 14 are lowered to place the cuvette 9 in the center of the optical path. The light generator 13 and wavelength receiver 14 work to measure the absorbance data. The stepper motor 5 can drive the positioning plate 6 to rotate, realize the switching of the cuvette 9, and realize the continuous detection of samples in different cuvettes 9.
