Description

Technical Field

[0001] This utility model relates to the field of resin cleaning and regeneration, and in particular to an ion exchange resin cleaning and regeneration system. Background Technology

[0002] Ion exchange resins are a class of polymeric materials with ion exchange capabilities. After a period of use, ion exchange resins can regain their exchange capacity through washing and regeneration. Current resin regeneration procedures involve transferring the old resin to a washing tank, then injecting demineralized water and manually stirring it. This process relies entirely on the operator's experience and judgment, such as determining the stirring time and monitoring the resin washing effect. If the test results show that the resin fails to meet usage standards, the manual rinsing and stirring process must be repeated. This method is inefficient and wastes manpower, and needs improvement. Summary of the Invention

[0003] Purpose of the invention: In order to overcome the shortcomings of the existing technology, this utility model provides an ion exchange resin cleaning and regeneration system, which aims to improve the automation level of resin cleaning and regeneration, so as to save manpower.

[0004] Technical Solution: To achieve the above objectives, this utility model provides an ion exchange resin cleaning and regeneration system, comprising a resin cleaning tank and an electrical control box. The resin cleaning tank is equipped with a stirring device, and an inlet pipe and an outlet pipe are connected to the tank. A control valve assembly is installed on the inlet pipe, and a water quality detection device is installed on the outlet pipe. A water level monitoring device is also installed on the resin cleaning tank. Both the water level monitoring device and the water quality detection device are electrically connected to the electrical control box to transmit water level and water quality information to the control box. The electrical control box is electrically connected to the control valve assembly to control the water supply from the inlet pipe to the resin cleaning tank.

[0005] Furthermore, a detection box is provided on the water outlet pipe, and the water quality detection device includes a conductivity electrode installed inside the detection box; a conductivity meter is installed inside the electrical control box, and the conductivity meter is electrically connected to the conductivity electrode to detect water quality by measuring conductivity.

[0006] Furthermore, the connection point between the resin cleaning tank and the water inlet pipe is the water inlet, and the top height of the detection box is not lower than the height of the water inlet; the water level monitoring device includes a float switch sensor installed in the detection box, and the float switch sensor is electrically connected to the electrical control box.

[0007] Furthermore, the control valve assembly includes a first ball valve, an inlet electric valve, an inlet flow meter, and a check valve arranged sequentially along the water inlet direction, wherein the inlet electric valve and the inlet flow meter are both electrically connected to the electrical control box.

[0008] Furthermore, the stirring device includes a stirring shaft disposed inside the resin washing tank, and stirring blades are disposed on the stirring shaft; a motor is installed above the resin washing tank, and the motor drives the stirring shaft to rotate accordingly.

[0009] Furthermore, the top of the resin cleaning tank is provided with a resin inlet, and a movable flip-top is installed on the resin inlet; the bottom of the resin cleaning tank is connected to a resin discharge pipe, and a second ball valve is installed on the resin discharge pipe.

[0010] Furthermore, the resin cleaning tank is made of a transparent material.

[0011] Beneficial effects: The ion exchange resin cleaning and regeneration system of this utility model has the following beneficial effects:

[0012] 1) The cleaning status of the resin is determined by monitoring the water level and water quality in the resin cleaning tank; the electrical control box can control the resin cleaning process based on water quality and water level information, enabling the resin to be automatically cleaned and regenerated, saving manpower.

[0013] 2) A detection box is installed on the water outlet pipe.

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] As attached Figures 1 to 4The aforementioned ion exchange resin cleaning and regeneration system includes a resin cleaning tank 1 and an electrical control box 2. The resin cleaning tank 1 is equipped with a stirring device, and an inlet pipe 3 and an outlet pipe 4 are connected to it. After the resin is loaded into the resin cleaning tank 1, water is introduced into the tank through the inlet pipe 3. Then, the stirring device is activated to agitate and clean the resin. Furthermore, depending on the different needs during the resin cleaning and regeneration process, the inlet pipe 3 can also supply demineralized water, regeneration reagents, etc., to the resin cleaning tank 1.

[0020] A control valve assembly is installed on the inlet pipe 3 to control the water intake. A water quality detection device is installed on the outlet pipe 4 to detect the water quality flowing out of the outlet pipe 4. A water level monitoring device is also installed on the resin cleaning tank 1 to monitor the water level inside the resin cleaning tank 1. (See attached...) Figure 1 As shown, the electrical control box 2 is located on one side of the resin cleaning tank 1. Both the water level monitoring device and the water quality detection device are electrically connected to the electrical control box 2 to transmit water level and water quality information. The electrical control box 2 is electrically connected to the control valve group. The electrical control box 2 can adjust the control valve group according to the water level and water quality information to control the water supply from the inlet pipe 3 to the resin cleaning tank 1, thereby achieving automated cleaning and regeneration of the ion exchange resin.

[0021] In this invention, the cleaning process is controlled by combining water level and water quality information. Compared with manual cleaning, which relies on experience to judge the cleaning process, this method is more stable and can save manpower.

[0022] A detection box 5 is installed on the water outlet pipe 4, and a filter cap is installed at the water inlet end of the water outlet pipe 4. (See attached...) Figure 4 As shown, the water quality testing device includes a conductivity electrode 6 disposed within the testing box 5. A conductivity meter 7 is disposed within the electrical control box 2, and the conductivity meter 7 is electrically connected to the conductivity electrode 6, allowing the electrical control box 2 to measure the conductivity of the water flow within the testing box 5 via the conductivity electrode 6. By measuring the conductivity, the water quality is detected, thereby determining whether the resin has completed cleaning.

[0023] The connection point between the resin cleaning tank 1 and the water inlet pipe 3 is the water inlet 8, and the top height of the detection box 5 is not lower than the height of the water inlet 8. (See attached image) Figure 4 As shown, the water level monitoring device includes a float switch sensor 9 installed inside the detection box 5, which is electrically connected to the electrical control box 2. The water level inside the detection box 5 can be determined through the float switch sensor 9. Since the detection box 5 is connected to the resin cleaning tank 1 through the water outlet pipe 4, the water level inside the detection box 5 can reflect the water level inside the resin cleaning tank 1.

[0024] Since the conductivity electrode 6 and the float switch sensor 9 are both installed inside the detection box 5, and the detection box 5 is located outside the resin cleaning tank 1, the measurement of water quality and water level will not interfere with the stirring of the resin by the stirring device, making the structural design more reasonable.

[0025] As attached Figure 3 As shown, the control valve assembly includes a first ball valve 10, an inlet electric valve 11, an inlet flow meter 12, and a check valve 13 arranged sequentially along the water inlet direction. Both the inlet electric valve 11 and the inlet flow meter 12 are electrically connected to the electrical control box 2. The first ball valve 10 can be manually opened and closed, allowing the operator to manually open or close the inlet pipe 3. The inlet flow meter 12 provides flow information to the electrical control box 2, which can control the inlet flow rate via the inlet electric valve 11.

[0026] As attached Figure 2 As shown, the stirring device includes a stirring shaft 14 disposed inside the resin washing tank 1, and a plurality of stirring blades 15 disposed on the stirring shaft 14. A motor 16 is mounted above the resin washing tank 1, and the output shaft of the motor 16 is connected to the stirring shaft 14. The motor 16 can drive the stirring shaft 14 to rotate, thereby stirring the resin in the resin washing tank 1. The motor 16 is also electrically connected to the electrical control box 2, and the electrical control box 2 controls the start and stop of the motor 16.

[0027] The resin cleaning tank 1 has a resin inlet 17 at its top, and a movable flip-top 18 is installed on the resin inlet 17. Opening the movable flip-top 18 allows for easy addition of resin into the resin cleaning tank 1. During the stirring and cleaning process, the movable flip-top 18 is closed. The bottom of the resin cleaning tank 1 is connected to a resin discharge pipe 19, which is equipped with a second ball valve 20. After the resin has been cleaned and regenerated, the operator can open the second ball valve 20 to discharge the resin from the resin cleaning tank 1.

[0028] The resin cleaning tank 1 is made of a transparent material. The resin cleaning tank 1 is generally made of a corrosion-resistant material, therefore, the material of the resin cleaning tank 1 can be plexiglass. The transparent resin cleaning tank 1 facilitates observation of the resin cleaning process.

[0029] In operation, this invention involves adding resin into a resin cleaning tank 1. Cleaning, demineralized water, or regeneration reagents are supplied to the tank via the inlet pipe 3 to clean the resin. Waste liquid is discharged from the outlet pipe 4. A stirring device agitates the resin during the cleaning process. The electrical control box 2 obtains water quality and level information via the conductivity electrode 6 and the float switch sensor 9, thereby controlling the inlet flow rate of the inlet pipe 3 and the start / stop of the stirring device, thus achieving automated resin cleaning and regeneration. After the system has run for a period of time, once the outlet conductivity is confirmed to be stable and less than 0.2 μs, the stirring device can be stopped, the inlet electric valve 11 closed, and the second ball valve 20 opened to discharge the cleaned and regenerated resin.

[0030] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
