Description

Technical Field

[0001] This utility model relates to the field of water sample titration analysis technology, specifically a wastewater discharge water sample titration analysis device. Background Technology

[0002] Titration analysis is a classic and important quantitative analytical method in chemical analysis, widely used in environmental monitoring and water quality analysis. It is mainly used to determine various indicators of water samples, such as pH, chemical oxygen demand (COD), total phosphorus, total nitrogen, ammonia nitrogen, chloride ions, and hardness. Automatic potentiometric titrators are generally used for wastewater discharge, which is the mainstream choice in modern laboratories. They are particularly suitable for large batches of samples and wastewater samples with dark, turbid colors that are difficult to determine the endpoint with indicators, providing more accurate, objective, and efficient results. However, automatic potentiometric titrators often require changing different titrating reagents, which necessitates cleaning the tubing. This is usually done by directly rinsing with clean water and then filling the tubing with the new titrating reagent. Furthermore, since the electrodes are in contact with liquid, the exterior of the electrodes needs to be manually cleaned. Manual cleaning is not always thorough, leading to errors, and the liquid is prone to splashing out and difficult to handle. Therefore, we propose a titration analysis device for wastewater discharge samples. Utility Model Content

[0003] The present invention aims to solve the problems existing in the prior art or related technologies.

[0004] Therefore, the technical solution adopted by this utility model is as follows: a wastewater discharge water sample titration analysis device, including a titrator body, a titration component, a storage bottle, a clear water bottle, a lifting component, and a cleaning component. The rear side of the titrator body is electrically connected to a measuring electrode. The titration component is fixedly installed at the top of the titrator body. The storage bottle is fixedly connected to the titration component. The clear water bottle is placed inside the titrator body. The lifting component includes a hydraulic cylinder fixedly installed on the titrator body and an electrode support fixedly installed at the top of the hydraulic cylinder. The cleaning component includes a rotary motor fixedly installed on the titrator body, a fixing plate fixed to the output end of the rotary motor, a cleaning tube fixedly installed on the fixing plate, a plurality of spray holes opened on the inner side of the cleaning tube, a second delivery tube fixedly installed on the outer side of the cleaning tube, a water storage tank fixed to the second delivery tube, a delivery pump fixedly installed on the second delivery tube, and a water inlet pipe fixedly installed at the top of the water storage tank.

[0005] Preferably, the titration assembly includes a peristaltic pump fixedly disposed at the top of the titrator body, a suction tube fixedly disposed at the liquid inlet of the peristaltic pump, an internally threaded cap fixedly disposed on the suction tube, a first delivery tube fixedly disposed at the liquid outlet of the peristaltic pump, and a titration head fixedly disposed on the first delivery tube.

[0006] Preferably, the water bottle and the liquid storage bottle have the same structure, and the water bottle and the liquid storage bottle are respectively filled with water and titration reagent.

[0007] Preferably, it also includes a vertical rod, which is fixedly mounted on the top of the titrator body and passes through the electrode support.

[0008] Preferably, the plurality of nozzles are arranged in a circular pattern, and all of the nozzles are arranged obliquely downwards.

[0009] Preferably, the instrument also includes a waste liquid tank, which is fixedly installed on the rear side of the titrator body. A third delivery pipe is fixedly installed at the top of the waste liquid tank and is fixedly connected to the bottom of the cleaning pipe.

[0010] Preferably, a drain pipe is fixedly installed on the right side of the wastewater tank, and a valve is fixedly installed on the drain pipe.

[0011] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows: the rotating motor of the cleaning component can drive the cleaning tube to directly below the measuring electrode, and the delivery pump can transport the clean water in the water storage tank to the spray nozzle through the second delivery pipe. Then, the hydraulic cylinder of the lifting component can drive the measuring electrode to move up and down reciprocally through the electrode bracket. During the reciprocating movement, the clean water sprayed from the spray nozzle can clean the outside of the electrode, avoiding residual substances from affecting the next titration analysis. Compared with traditional manual cleaning, the cleaning is more thorough. At the same time, since the spray nozzle is angled downward, it can avoid water splashing out and increasing the difficulty of cleaning. The third delivery pipe can transport the wastewater after cleaning to the wastewater tank for centralized treatment. Attached Figure Description

[0022] Specifically, it also includes a vertical rod 600, which is fixedly installed at the top of the titrator body 100 and passes through the electrode support 502. During use, the vertical rod 600 ensures that the electrode support 502 can only move vertically up and down, which can improve the stability of the movement of the electrode support 502.

Then, the rotating motor 701 can drive the fixing plate 702 and the cleaning pipe 703 to rotate so that the cleaning pipe 703 can move to directly below the measuring electrode 101.

[0024] Example 2 Reference Figure 1This is the second embodiment of the present invention, which differs from the first embodiment in that it also includes a waste liquid tank 800. The waste liquid tank 800 is fixedly installed on the rear side of the titrator body 100. A third conveying pipe 801 is fixedly installed at the top of the waste liquid tank 800, and the third conveying pipe 801 is fixedly connected to the bottom of the cleaning pipe 703.

The operating peristaltic pump 201 will transport the water in the water bottle 400 through the suction pipe 202 and the first delivery pipe 204 to the titration head 205 for spraying, thus rinsing the pipeline. Then, control the rotary motor 701 to operate. The operating rotary motor 701 can drive the cleaning pipe 703 to rotate to the measuring electrode 101 via the fixing plate 702. Directly below, the pump 705 is controlled to operate. The operating pump 705 can transport the clean water in the water storage tank 706 to the nozzle 7031 through the second conveying pipe 704. At the same time, the hydraulic cylinder 501 is controlled to drive the measuring electrode 101 to move up and down through the electrode bracket 502. The clean water sprayed from the nozzle 7031 will wash the moving measuring electrode 101. The cleaned sewage will enter the sewage tank 800 through the third conveying pipe 801 for storage. Then, the valve 803 can be rotated to open the drain pipe 802. After opening, the sewage can be discharged through the drain pipe 802.
