Description

Technical Field

[0001] The utility model belongs to the technical field of water quality analysis equipment, and specifically relates to an improvement in the structure of a multi-parameter water quality analyzer. Background Art

[0002] Water is the source of life. Humans cannot do without water in their life and production activities. The quality of domestic drinking water is closely related to human health. With the development of industry, water resources have been gradually damaged. In order to protect the water environment, it is necessary to strengthen the monitoring of sewage discharge. A water quality analyzer is a device that uses chemical and physical methods to measure various parameters in the water environment, and corresponding treatment plans are formulated based on various parameters.

[0003] For existing water quality detection instruments, when detecting substances contained in some water quality, such as the content test of iron, manganese or aluminum, only single-parameter detection can be achieved, that is, one instrument can only detect one parameter, and it is impossible to detect multiple parameters on the same instrument. If multiple parameters in the water quality need to be detected, they need to be measured separately on multiple different water quality detection instruments, and cannot be flexibly combined, which cannot meet different detection requirements.

[0069] In some embodiments of the present application, a water quality multi-parameter analyzer is proposed, including:

[0072] A sample storage component 200, arranged at the sample storage area 110, and a plurality of sample storage positions 210 are arranged on the sample storage component 200 for placing the sample bottles to be measured.

[0073] In some embodiments of the present application, the sample storage component 200 is detachably connected to the sample storage area 110 of the housing 100 to facilitate the placement or removal of the sample bottles above it.

[0074] The sample storage positions 210 are sample storage holes provided on the sample storage component. A plurality of them are provided and cover the sample storage component 200. The sample bottles to be tested are inserted into the sample storage holes to achieve the storage function.

[0075] One or more sample storage components 200 can be provided to store the sample bottles to be tested.

[0076] In some embodiments, there is also formed on the housing 100: a titration area 120, and a plurality of titration positions 121 are arranged at the titration area 120.

[0077] The titration positions 121 are titration insertion hole positions formed in the titration area 120. The sample bottles for titration will be inserted at the titration positions 121 for subsequent titration operations.

[0078] By providing a plurality of titration positions 121 in the titration area 120, titration operations can be performed on multiple sample bottles simultaneously to meet the titration requirements for different water quality detection parameters and ensure that the titration operations can be carried out simultaneously when the entire device detects multiple water quality parameters.

[0079] A liquid addition area 130, and a liquid addition position 131 is provided at the liquid addition area 130;

[0080] In some embodiments, the liquid addition position 131 is a liquid addition hole position formed on the housing 100. The sample bottles for heating can be placed at the liquid addition hole position for subsequent liquid addition operations.

[0081] When setting the liquid addition position 131, multiple ones can be provided to enable it to meet the requirement of simultaneously performing liquid addition operations on multiple sample bottles, ensure synchronous operation of liquid addition, and prevent mutual interference and influence between them.

[0082] A first robotic arm 200 is movably connected to the housing 100, and a set of color sensing elements and a titration assembly 500 are provided above it. The first robotic arm 200 drives the color sensing elements and the titration assembly 500 to move cyclically in the titration area 120.

[0083] The color sensing elements are color sensors. The color sensing elements are used to identify and determine the color change of the sample to be tested. The sample can directly determine the color end point through the color sensor, improving the accuracy of determination.

[0084] The titration assembly 500 is mainly used to perform liquid addition titration on the samples at the titration area 120. Providing a set of color sensing elements and a titration assembly 500 can reduce production costs.

[0085] The titration assembly 500 includes a titration burette and a titration plunger pump communicated with the titration burette.

[0086] The effect of quantitative dosing can be achieved through the titration plunger pump, and the addition amount of the required reagent can be accurately controlled.

[0087] When the second robotic arm 300 slides along the base 170, it can drive the color sensing element and the titration assembly 500 to move cyclically within the titration area 120, realizing the sequential cyclic titration of the samples inside the titration area 120.

[0088] That is, the titration of the first sample is carried out first. After the titration of the first sample is completed, the second robotic arm 300 moves to the second sample for titration. In cyclic titration, after the titration of the first sample, the second robotic arm 300 can continue the titration and color determination of the second sample without waiting for the first sample to react. By the cyclic titration method, the time for waiting for the sample to react after titration is omitted, improving the titration efficiency.

[0089] To realize the control of the second robotic arm 300 that can move along the machine housing 100, the water quality multi-parameter analyzer is also provided with a controller.

[0090] To realize cyclic titration, the second robotic arm 300 is correspondingly configured with a first slider and a first driving device connected thereto. The first driving device can be a motor or a cylinder, etc. The first driving device is correspondingly communicatively connected to the controller. The controller can send a control signal to drive the first slider to act. A first horizontal slide rail is provided on the machine housing 100. When the first driving device acts, it drives the first slider to move back and forth between the titration positions 121 in the titration area 120 along the first horizontal slide rail, realizing the titration of the titration positions 121 in the titration area 120.

[0091] For the second robotic arm 300, a liquid adding assembly 400 is arranged above it. The second robotic hand is movably connected to the machine housing 100 to drive the liquid adding assembly 400 above it to move in the liquid adding area 130.

[0092] The second robotic arm 300 is connected with a second slider and a second driving device. There is a second horizontal slide rail on the machine housing 100. The second driving device drives the second robotic arm 300 to move along the second horizontal slide rail to drive the liquid adding assembly 400 to move back and forth for liquid adding operation.

[0093] In some embodiments, the liquid adding assembly 400 includes: a liquid adding plunger pump and a liquid adding pipe communicated with the liquid adding plunger pump. The liquid adding pipe has a liquid adding port.

[0094] The effect of quantitative dosing can be achieved through the liquid adding plunger pump, and the addition amount of the required reagent can be accurately controlled.

[0095] A heating zone 140, where a heating position 141 is arranged;

[0096] In some embodiments, the heating position 141 is a heating hole formed on the housing 100 for placing a sample bottle to be heated.

[0097] A heating module 610, disposed below the heating position 141, for heating the sample placed in the heating position 141. By means of the heating module 610, the effect of heating the sample bottle at the heating position 141 can be achieved.

[0098] A cooling zone 150, in which a plurality of cooling positions 151 are provided;

[0099] In some embodiments, the cooling position 151 is a cooling hole formed on the housing 100 for placing a sample bottle to be cooled.

[0100] By providing a plurality of cooling holes, cooling of a plurality of sample bottles can be achieved at one time, improving the cooling efficiency.

[0101] A cooling module 700, arranged below the cooling position 151, for cooling the sample placed in the cooling position 151. By means of the cooling module 700, cooling of the sample is achieved to meet the cooling step requirements in the water quality parameters to be detected.

[0102] A third manipulator 810, for grasping the sample;

[0103] A three-way motion mechanism, connected to the third manipulator 810, driving the third manipulator 810 to move in three directions of X, Y, and Z to achieve the transfer of the sample between the sample storage position 210, the dropping position 121, the heating position 141, the liquid adding position 131, and the cooling position 151.

[0104] The three-way motion mechanism is an existing XYZ three-way motion mechanism, which includes an X-direction motion mechanism, a Y-direction motion mechanism, and a Z-direction motion mechanism.

[0105] When connecting, the Y-direction motion mechanism is connected to the X-direction motion mechanism, the Z-direction motion mechanism is connected to the Y-direction motion mechanism, and the third manipulator 810 is connected to the Z-direction motion mechanism.

[0106] When moving, when the X-direction motion mechanism acts, it drives the Y-direction motion mechanism, the Z-direction motion mechanism, and the third manipulator 810 to move in the X direction; when the Y-direction motion mechanism acts, it drives the Z-direction motion mechanism and the third manipulator 810 to move in the Y direction; when the Z-direction motion mechanism acts, it drives the third manipulator 810 to move in the Z direction.

[0107] The third manipulator 810 can select an existing manipulator mechanism.

[0108] Driving the third manipulator 810 to move in three directions through a three-way motion mechanism enables the third manipulator 810 to grasp samples at the positions on the sample storage position 210, the dropping position 121, the heating position 141, the liquid adding position 131, and the cooling position 151, and at the same time transfer the samples at the above-mentioned various workstations, realizing the automatic picking and placing of samples and improving the operation efficiency.

[0109] A spectrophotometer 910 is assembled on the housing 100 for analyzing water quality parameters.

[0110] In some embodiments, the spectrophotometer 910 can select an existing structure for analyzing and determining the results by colorimetry and recording the colorimetric analysis conclusion at the same time.

[0111] A sampling component 820 is connected to the three-way motion mechanism and can move in three directions under the drive of the three-way motion mechanism to extract sample reagents and inject them into the spectrophotometer 910 for water quality analysis.

[0112] In some embodiments, the sampling component 820 is a sampling needle, which can be used to sample the sample to be tested and inject it into the spectrophotometer 910 for analysis.

[0113] To ensure that the sampling component 820 can conveniently extract the water sample and move it to the spectrophotometer 910, it is correspondingly connected to the Z-direction motion mechanism of the three-way motion mechanism, and can automatically sample the sample to be tested in the sample position by moving up and down when moving to the sample position.

[0114] In this embodiment of the water quality multi-parameter analyzer, when setting, a plurality of processing positions for processing water quality and corresponding processing components are correspondingly provided on the housing 100. The plurality of processing positions include: the dropping position 121, the heating position 141, and the liquid adding position 131. The processing components correspondingly configured at the above-mentioned processing positions are: a titration component 500 connected to the first robotic arm 200, a heating module 610, and a liquid adding component 400 connected to the second robotic arm 300;

[0115] When detecting a plurality of different parameters of water quality, the third manipulator 810 can be driven to move the sample to be tested to different processing positions respectively, and the sample is processed by the processing components at the corresponding processing positions. After the processing is completed, the sampling component 820 can be used to extract and transfer it to the spectrophotometer 910 for colorimetric analysis respectively;

[0116] The detection and analysis of multiple water quality parameters are achieved by a single device. When conducting the detection and analysis, different treatment positions can be flexibly selected and combined according to the different water quality parameters that actually need to be detected, so as to meet the different detection requirements of different water quality parameters.

[0117] For example, the operation steps when testing and analyzing iron in water quality are as follows:

[0118] For 50 mL of water sample or standard series sample, add 4 mL of hydrochloric acid and 1 mL of hydroxylamine hydrochloride solution, heat and concentrate to about 30 mL, cool to room temperature, then add 2 mL of phenanthroline solution. After mixing, add 10 mL of ammonium acetate buffer solution, mix well and let stand for 10 - 15 minutes. Colorimetric analysis is carried out through a 2 cm colorimetric cell in a spectrophotometer at a wavelength of 510 nm.

[0119] From the above steps, it can be seen that when testing and analyzing iron, the liquid adding position 131, heating position 141, cooling position 151 and spectrophotometer 910 are required.

[0120] The operation steps when testing and analyzing manganese in water quality are as follows:

[0121] For 50 mL of water sample or standard series sample, add 2.5 mL of silver nitrate - mercury sulfate solution, heat and concentrate to about 45 mL, remove and let cool slightly. Then add 5 mL of ammonium persulfate solution, heat to boiling again, let stand for 1 minute and then cool in a water bath. Make up the volume to 50 mL with pure water and mix well. Colorimetric analysis is carried out with a 5 cm colorimetric cell at a wavelength of 530 nm.

[0122] From the above steps, it can be seen that when testing and analyzing manganese, the liquid adding position 131, heating position 141, cooling position 151 and spectrophotometer 910 are required.

[0123] The operation steps when testing and analyzing aluminum in water quality are as follows:

[0124] For 25 mL of water sample or standard series sample, add 1 drop of p - nitrophenol ethanol and 1 drop of ammonia water until it turns light yellow. Add nitric acid solution until the yellow color disappears (color recognition) and then add 2 more drops. Add 3.0 mL of chromazurol S solution and mix well. Add 1.0 mL of OP solution, 2.0 mL of CPB solution, 3.0 mL of ethylenediamine - hydrochloric acid buffer solution, add water to make up the volume to 50 mL, mix well and let stand for 30 minutes. Through a 2 cm colorimetric cell in a spectrophotometer, measure the absorbance at a wavelength of 620 nm with the reagent blank as the reference.

[0125] For the test of aluminum, the liquid adding position 131, dropping position 121 and spectrophotometer 910 are used.

[0126] It can be seen that the steps required for testing different parameters are different, and the processing positions adopted are also different. The multi-parameter water quality analyzer in this embodiment can meet the use requirements for testing different water quality parameters when in use. During measurement, it only needs to perform transformation and combination of each processing position according to different test parameters, and integrate the tests of multiple parameters onto one device, making the test operation more convenient and fast.

[0127] In some embodiments of the present application, the cooling module 700 includes:

[0135] The sample is inserted into the cooling water tank for heat dissipation, transferring the heat to the water flow. The water circulates through the cooling water pipe 720 to the cooling radiator 740, and exchanges heat with the refrigerator 730 in contact with the cooling radiator 740 to absorb the heat of the water flow in the cooling radiator 740, so that the water flowing back to the cooling water tank after passing through the cooling radiator 740 is the water that has undergone cooling and heat exchange, and can continue to exchange heat with the sample bottle to cool the sample bottle.

When the cooling and heat dissipation fan starts, it drives the air flow to accelerate the circulating flow, thereby accelerating the heat exchange.

[0137] In some embodiments of the present application, it further includes: a weighing module 620, connected below the heating module 610, for detecting the weight of the heated sample.

The heated sample can be weighed by the weighing module 620 connected below the heating module 610 to determine the heating end point.
