[0002] In chemical water treatment systems, the measurement of water sample conductivity helps to determine the water quality. Conductivity meters are commonly used instruments for detecting conductivity. In order to improve the sensitivity of water quality detection, sampled water is usually passed through a resin exchange column for ion exchange to separate the original anions and cations in the water. For example, converting cations in the water into hydrogen ions can reduce the interference of some ions on conductivity measurement. The conductivity of the tested water sample is then detected by a conductivity meter, thereby improving the accuracy of water quality detection. Since the resin in the resin exchange column is a consumable, the expiration time is usually 3 to 5 days, and the resin needs to be replaced regularly.

[0003] In the prior art, the resin is usually replaced manually, that is, the staff manually replaces the resin in the resin exchange column regularly to ensure the accuracy of the conductivity measurement of the sampled water by the conductivity meter. Specifically, the staff needs to first close the flow of the sampled water, then manually open the end cap of the resin exchange column, discharge the resin particles in the resin exchange column, add new resin particles, and close the end cap of the resin exchange column to complete the replacement of the resin.

[0004] Regarding the above-mentioned related technologies, when replacing the resin, the circulation of the sampled water is closed, which affects the online display of the conductivity meter. The manual replacement efficiency is low, and the resin replacement of multiple resin exchange columns is time-consuming and labor-intensive. Utility Model Content

The automatic resin filling device can replenish resin to the resin inlet 24 and control the resin outlet 25 to discharge resin.

[0032] When it is necessary to replace the failed resin, the failed resin in the resin exchange column 21 is discharged from the resin outlet 25 through the resin filling mechanism 3, and new resin is added to the resin exchange column 21 from the resin inlet 24, thereby realizing the replacement of the resin. Moreover, the device can replace the resins in multiple resin exchange columns 21 at the same time, with high efficiency, small workload for staff, short working hours, and can achieve obvious effect of reducing costs and increasing efficiency.

[0033] Reference Figure 2 The sampling water inlet 22 and the sampling water outlet 23 are located on the side of the resin exchange column 21, the sampling water inlet 22 is located at the top of the resin exchange column 21, and the sampling water inlet 22 is arranged downwardly and tilted near the resin exchange column 21, the sampling water outlet 23 is located at the bottom of the resin exchange column 21, and the sampling water outlet 23 is arranged upwardly and tilted near the resin exchange column 21, so that the sampling water can flow into and out of the resin exchange column 21.

[0034] When discharging the spent resin, sampling water continuously enters the resin exchange column 21 from the sampling water inlet 22 and is discharged from the sampling water outlet 23. The spent resin is discharged from the resin outlet 25 by gravity. The continuously flowing sampling water can push the spent resin to be discharged and can also flush the inner wall of the resin exchange column 21.

The combination valve 32 is provided with a single valve body inlet and multiple diversion outlets. The number of diversion outlets is greater than or equal to the number of resin exchange columns 21. In this embodiment, the number of diversion outlets is set to ten. The combination valve 32 is fixedly installed on one side of the storage cabinet 6. The two ends of the feed pipe 31 are respectively connected to the resin inlet 24 and the diversion outlet, and the multiple feed pipes 31 correspond to the multiple diversion outlets one by one.

The discharge valve 33 is a straight-through solenoid valve or a pilot-operated solenoid valve. In this embodiment, the discharge valve 33 is a straight-through solenoid valve, and the discharge valve 33 is connected to the resin outlet 25 .

[0037] When the expired resin is cleared through the resin filling mechanism 3, the discharge valve 33 controls the resin outlet 25 to discharge the expired resin, the feed pump pumps the new resin to the feed pipe 34, and the combination valve 32 controls the feed pipe 34 to introduce the resin into any feed pipe 31, so as to realize automatic replacement of the resin in the resin exchange column 21 without manual replacement, thereby improving the efficiency of replacing the resin.

[0039] Reference Figure 3 and Figure 4, the conductivity meter is fixed inside the containing cabinet 6, and the conductivity meter continuously measures the conductivity of the sample water. A control unit 4 is fixed on the side wall of the containing cabinet 6 to facilitate the operation of the staff.

The display screen 41 can display the detection data of the conductivity meter. The conductivity meter control module 42 is used to operate the conductivity meter. The automatic filling start and stop button 43 is used to control the start and stop of the feed pump. The valve control assembly is used to control the start and stop of the combination valve 32 and the discharge valve 33. By concentrating the control of the conductivity meter and the resin filling mechanism 3 on a control unit 4, it is convenient for the staff to operate, thereby further improving the work efficiency of replacing the resin.

[0040] When the staff replaces the failed resin in the resin exchange column by manual operation, the resins in multiple resin exchange columns need to be replaced in turn, which is inefficient and the sampling water needs to be turned off, affecting the online display of the conductivity meter. It takes ten minutes to manually replace the resin in a resin exchange column 21, and a total of one hundred minutes to replace the resin in ten resin exchange columns. After adopting the online conductivity meter resin replacement device and use method, the resin replacement of a batch of ten resin exchange columns only takes three minutes, and there is no need to turn off the sampling water, which greatly improves the work efficiency, keeps the online monitoring of the conductivity meter real-time and accurate, ensures the water quality, ensures the safe and stable operation of the host equipment, and also improves the economic benefits of the enterprise, with obvious cost reduction and efficiency improvement.

[0041] The implementation principle of the online conductivity meter resin replacement device and use method of the embodiment of the present application is as follows: the sampling water inlet 22 and the sampling water outlet 23 are changed to the side in the cross section of the resin exchange column 21, and a resin inlet 24 is added to the top of the resin exchange column 21, and a resin outlet 25 is added to the bottom to form a resin channel. The control unit controls the resin outlet 25 to discharge the resin and the resin inlet 24 to replenish the resin, so as to realize the automatic replacement of the failed resin in the resin exchange column 21. During the resin replacement, the continuously flowing sampling water can play a role in assisting drainage and cleaning, and can maintain the real-time and accuracy of the conductivity meter display.
