Abstract
Description
Technical Field
[0001] This utility model relates to a multi-parameter water quality analyzer. Background Technology
[0002] With the rapid development of industrialization and urbanization, the demand for water quality testing and regulation is constantly increasing. Existing water quality analysis systems mostly adopt single analysis and testing, which cannot comprehensively analyze the chemical and physical properties of water bodies.
[0003] For example, the utility model with publication number 215812740U discloses a water quality analysis instrument. The detection mechanism used is relatively traditional and does not have a rotating disc or other mechanism, making it difficult to support the rapid detection of multiple water quality data.
[0004] Therefore, it is necessary to design a new type of comprehensive water quality parameter analysis. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide a multi-parameter water quality analyzer that can detect multiple parameters, has a compact structure, and rich functions.
[0006] The technical solution of the utility model is as follows:
[0007] A multi-parameter water quality analyzer is characterized by comprising a base and a reaction plate (1), a reagent plate (2), a sampling needle movement mechanism (3), a colorimetric cell (4), a cleaning cell (5), and a liquid circuit module (6) disposed on the base plate.
[0008] Both the reaction disk module and the reagent disk module are driven by a turntable drive mechanism;
[0009] An empty reaction tube (11), a reagent bottle (12), and a mother liquor tube (13) are set in the reaction dish; the mother liquor refers to a high-concentration, pre-prepared solution, which is usually used for subsequent dilution and further reaction.
[0010] The reagent tray contains multiple sample bottles (21) arranged circumferentially.
[0011] The liquid circuit module and sampling needle movement mechanism are used for aspirating and dispensing sample liquid, reaction solution, mixture and water;
[0012] Colorimetric cells are used to perform multi-water quality parameter testing.
[0013] The turntable drive mechanism includes a drive motor and a synchronous belt drive unit.
[0014] The sampling needle motion mechanism includes a rotary drive unit and a lifting drive unit.
[0015] The colorimetric cell has eight filter wheels (for detecting multiple parameters).
[0016] Beneficial effects:
[0017] This utility model of a multi-parameter water quality analyzer integrates modules such as a reagent tray, a reaction tray, a sample needle drive mechanism, and a colorimetric cell, featuring a compact structure and rich functionality. Attached Figure Description

Detailed Implementation
[0028] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:
[0029] Example 1: As Figure 1-3 The multi-parameter water quality analyzer mainly includes a reagent tray module, a reaction tray module, a liquid path module, a sampling needle movement module, a colorimetric cell module, and a cleaning tray module. To achieve a compact overall size while maintaining good maintainability, the various modules need to be rationally arranged.
[0030] Figure 4-5The image shows an isometric view of the reaction dish and reagent dish. The reagent dish contains sample bottles, while the reaction dish contains empty reaction tubes, reagent bottles, and mother liquor tubes. The reagent dish and reaction dish use independent but structurally identical transmission components. A motor drives a synchronous pulley via a belt. A shaft fixed to the synchronous pulley rotates within a bearing housing. A rotating part is fixed at the top, and four screw holes on this part mate with four holes in the center of the reaction dish and reagent dish to achieve the transmission purpose.
[0031] like Figure 6 For the sake of instrument compactness, the cleaning tank, reaction tank, colorimetric cell module, and waste liquid tank are all arranged together. The cleaning tank is used to clean the sampling needle, while the reaction tank, connected to the colorimetric cell module, is mainly used for the detection of the reaction solution.
[0032] Figure 7 The sampling needle movement module covers the reagent tray, reaction tray, and cleaning tank. During the workflow, after a water blank reading (the instrument pumps water from the buffer tank into the colorimetric cell for reading, which verifies the accuracy of the instrument's optical module), the sampling needle draws sample liquid from the reagent tray and injects it into the reaction tube of the reaction tray. It then sequentially draws reagents from the reagent bottles, cleaning the needle after each step. After the last reagent is drawn and expelled, the needle completes the aspiration and regurgitation mixing in the reaction tube. After the reaction time, the reaction solution is drawn, injected into the reaction tank, pumped into the colorimetric cell, and the detection is completed. The colorimetric cell is then cleaned after the detection is complete. This device can test the content of different elements in a sample when the reaction solution enters the colorimetric cell.
[0033] The colorimetric cell contains eight different filter wheels. Light passes through different filters and then through different reaction solutions, before being received by an optical sensor. This signal reflects the content of a specific element in the reaction solution.
[0034] Figure 8 and Figure 9 The frame module is mainly made of aluminum plate. The front lower panel 61 and the rear lower panel 63 are connected to the base plate, and the rear upper panel 64 is set on the rear lower panel 63. The top cover is connected to the bottom device through a hinge, forming a closed and sturdy frame.
[0035] Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model shall be included within the protection scope of this utility model.
