Technical Field

[0001] This utility model relates to the field of water quality testing technology, and in particular to a multi-parameter online water quality testing reagent quantitative dispensing device. Background Technology

[0002] Multi-parameter online water quality testing is a device used to detect water quality. It can simultaneously measure multiple water quality parameters, which is of great significance for water resource management, environmental monitoring, and water treatment process control. During the testing process, chemical reagents are quantitatively added to the test tube through a reagent quantitative dispensing device and react with the water being tested.

[0003] Existing reagent quantitative dispensing devices require test tubes to be placed on top of the device during use, and chemical reagents are quantitatively dispensed into the test tubes through the delivery tube at the top of the device. Because the reagent quantitative dispensing device does not fix the test tubes, the test tubes are prone to shaking or shifting, which leads to inaccurate injection of chemical reagents into the test tubes and affects the accuracy of subsequent detection. In view of this, this solution proposes a multi-parameter online water quality detection reagent quantitative dispensing device to solve the above problems. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] refer to Figure 1-4 As shown:

[0033] Example 1: This utility model provides a multi-parameter online water quality testing reagent quantitative dispensing device, comprising:

[0034] Quantitative scale 1;

[0035] Mounting bracket 2 is fixedly installed on one side of the quantitative scale 1;

[0036] The dispensing section is located on the side of the mounting frame 2 near the quantitative scale 1, and is used for dispensing reagents.

[0037] Specifically, the refueling section includes:

[0038] Connecting plate 3, one side of connecting plate 3 is attached to the side of mounting bracket 2 near quantitative scale 1;

[0039] Support frame 4, one end of support frame 4 is fixedly connected to the end of connecting plate 3 away from mounting frame 2;

[0040] The filling pipe 5 has one end inserted into the end of the support frame 4 that is away from the connecting frame;

[0041] Furthermore, the mounting bracket 2 has a mounting groove on the side near the quantitative scale 1, and a torsion block 7 is attached to the side of the mounting bracket 2 away from the quantitative scale 1. A connecting rod 6 is fixedly installed on the end of the torsion block 7 near the mounting groove. The outer wall of the connecting rod 6 is threaded. The end of the connecting rod 6 away from the torsion block 7 passes through the mounting groove and is threadedly connected to the end of the connecting plate 3 away from the support frame 4.

[0042] It should be noted that the quantitative scale 1 is used to weigh test tubes and detect and control the weight of injected chemical reagents. The quantitative scale 1 is used in conjunction with a metering pump, and is connected to the metering pump via a data cable or Bluetooth. The quantitative scale 1 transmits data to the processing unit of the metering pump, thereby controlling the amount of chemical reagent injected by the metering pump. One end of the mounting bracket 2 is fixedly connected to one side of the quantitative scale 1. The side of the mounting plate near the quantitative scale 1 is attached to the connecting plate 3. The end of the connecting plate 3 away from the mounting bracket 2 is fixedly connected to the support frame 4. The end of the support frame 4 away from the connecting frame is inserted into the filling tube 5. The end of the filling tube 5 away from the support frame 4 is fixedly connected to the output end of the metering pump. The outer wall of the connecting rod 6 is threaded. One end of the connecting rod 6 passes through the mounting groove and is threadedly inserted into the end of the connecting plate 3 away from the support frame 4. The end of the connecting rod 6 away from the connecting plate 3 is fixedly connected to the torsion block 7. The torsion block 7 is close to the connecting rod 6. One end of the tube is attached to the side of the mounting frame 2 away from the quantitative scale 1. The test tube is placed on the top of the quantitative scale 1 and fixed by the cooperation of the fixing frame 8 and the fixing part. The support frame 4 is pushed, and the movement of the support frame 4 drives the movement of the dispensing tube 5, so that the output end of the dispensing tube 5 is slightly higher than the top of the reagent. The movement of the support frame 4 drives the movement of the connecting plate 3. The torsion block 7 is rotated, and the rotation of the torsion block 7 drives the rotation of the connecting rod 6, so that the connecting rod 6 is threadedly connected to the connecting plate 3. The movement of the connecting rod 6 makes the torsion block 7 fit against the surface of the mounting frame 2, thereby fixing the connecting plate 3 and the mounting frame 2 and preventing the support frame 4 from moving during the dispensing process. The quantitative scale 1 detects the weight of the test tube and controls the metering pump to add the chemical reagent into the test tube through the dispensing tube 5. During the dispensing process, the quantitative scale 1 detects the weight of the injected chemical reagent. When the weight of the added chemical reagent reaches the standard, the quantitative scale 1 controls the metering pump to shut off, thereby completing the quantitative dispensing.

[0043] The fixing frame 8 is fixedly installed on the top of the quantitative scale 1, and the end of the fixing frame 8 away from the quantitative scale 1 has multiple fixing slots.

[0044] The fixing part is set in the fixing groove and is used to fix the test tube and the fixing frame 8.

[0045] Specifically, the fixing part includes:

[0046] Fixed rod 9, one end of multiple fixed rods 9 is slidably inserted into multiple fixed grooves;

[0047] A sliding member is provided at the top of the fixed rod 9 and is used to connect the fixed rod 9 and the adjusting part.

[0048] Furthermore, the sliding member includes a sliding rod 10, one end of the plurality of sliding rods 10 is fixedly connected to the top of the end of the plurality of fixed rods 9 near the fixed groove, and the end of the plurality of sliding rods 10 away from the fixed rods 9 is slidably inserted into the adjustment part;

[0049] It should be noted that the fixing frame 8 is fixedly connected to the top of the quantitative scale 1, and one end of each of the multiple fixing rods 9 is slidably inserted into multiple fixing slots. The top of the ends of the multiple fixing rods 9 near the fixing slots is fixedly connected to multiple sliding rods 10. When the test tube is placed in the fixing frame 8, the sliding rods 10 are moved by the adjustment part. The movement of the sliding rods 10 causes the fixing rods 9 to move, so that the fixing rods 9 move closer to each other and fit against the outer wall of the test tube. The multiple fixing rods 9 work together to clamp and fix the test tube, and place the test tube in the middle of the fixing frame 8. This prevents the chemical reagent from being inaccurately injected into the test tube due to shaking when adding chemical reagents later, thus improving stability.

[0050] The adjustment part is located on the top of the fixed frame 8 and is used to adjust the movement of the fixed part;

[0051] Specifically, the regulating section includes:

[0052] Adjustment frame 11, the bottom of adjustment frame 11 is rotatably connected to the top of fixed frame 8, and multiple adjustment slots are opened on the top of adjustment frame 11. The multiple adjustment slots are slidably inserted and connected to the end of sliding rod 10 away from fixed rod 9.

[0053] Push rod 12, one end of which is fixedly connected to the outer wall of adjustment frame 11;

[0054] It should be noted that the bottom of the adjusting frame 11 is rotatably connected to the top of the fixed frame 8, and multiple adjusting grooves are slidably inserted into the end of the sliding rod 10 away from the fixed rod 9. The outer wall of the adjusting frame 11 is fixedly connected to the push rod 12. When the test tube is placed in the fixed frame 8, the adjusting frame 11 is rotated by the rotation of the push rod 12, which in turn drives the adjusting grooves to rotate, causing the sliding rod 10 to move according to the shape of the adjusting grooves. The movement of the sliding rod 10 drives the fixed rod 9 to move, so that the fixed rods 9 move closer to each other and fit against the outer wall of the test tube. The multiple fixed rods 9 work together to clamp and fix the test tube, and place the test tube in the middle of the fixed frame 8. This prevents the chemical reagent from being inaccurately injected into the test tube due to shaking when adding chemical reagents later, thus improving stability.

[0055] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
