In the pure water production device, EDI is an important part of the current full membrane process. Among them, EDI (Electrodeionization), also known as continuous electrolytic desalination technology, scientifically integrates electrodialysis technology and ion exchange technology. Through the selective permeation of anions and cations and the exchange of ions in water by ion exchange resins, the directional migration of ions in water is achieved under the action of the electric field, thereby achieving deep purification and desalination of water.

Therefore, the outlet pipe of the EDI equipment needs to be grounded to let the static electricity enter the earth through the ground wire. However, due to the moment when the EDI equipment is shut down, the outlet pipe will generate back pressure, which causes the water in the outlet pipe to form water hammer, and the water purification module in the EDI equipment is not resistant to water hammer impact, which can easily cause damage to the water purification module in the EDI equipment.

The buffer component 3 is arranged on the water outlet pipe 2. The buffer component 3 is used to control the on and off of the water outlet pipe 2.
[0021] The water outlet pipe 2 includes a first pipe 21 and a second pipe 22, and the first pipe 21 and the second pipe 22 are connected by a flange. The flange includes a first flange plate 23 and a second flange plate 24. The first flange plate 23 is arranged outside the first pipe 21, and the second flange plate 24 is arranged outside the second pipe 22. The buffer assembly 3 is arranged between the first flange plate 23 and the second flange plate 24.
[0022] Furthermore, the first flange plate 23 and the second flange plate 24 are fastened together by bolts. Specifically, a plurality of through holes (not shown) are provided on the first flange plate 23 and the second flange plate 24. During installation, the bolts are passed through the through holes and then connected with nuts. In this embodiment, the water flow direction of the water outlet pipe 2 is from the first pipe 21 to the second pipe 22, so that Figure 2 Taking the direction of the water as an example, the arrow from left to right is the direction of water flow.
[0023] The buffer assembly 3 includes a fixing part 31, a sleeve 30, an elastic part 32, a valve plate 33, a limiting ring 34, a guide rod 35 and a grounding column 36. The fixing part 31 is a circular plate structure. The fixing part 31 is arranged between the first flange plate 23 and the second flange plate 24. The sleeve 30, the elastic part 32, the valve plate 33, the limiting ring 34, the guide rod 35 and the grounding column 36 are all arranged on the fixing part 31. Specifically, the sleeve 30, the elastic part 32, the valve plate 33 and the limiting ring 34 are all located in the fixing part 31, and the guide rod 35 and the grounding column 36 are both located at the bottom of the fixing part 31.
[0024] A accommodating groove 311 is provided on the fixing member 31, and the sleeve 30, the elastic member 32, the valve plate 33 and the limiting ring 34 are arranged in the accommodating groove 311. The sleeve 30 is fixedly connected to the bottom wall of the accommodating groove 311, and the valve plate 33 is movably arranged between the sleeve 30 and the limiting ring 34. The elastic member 32 is sleeved on the outside of the sleeve 30, and the elastic member 32 is elastically supported between the bottom wall of the accommodating groove 311 and the valve plate 33. Specifically, one end of the elastic member 32 is fixedly connected to the bottom wall of the accommodating groove 311, and the other end of the elastic member 32 is fixedly connected to the valve plate 33, so that the valve plate 33 can be driven to move in the accommodating groove 311. The limiting ring 34 is a circular ring structure, and is fixedly connected to the groove wall of the accommodating groove 311. The limiting ring 34 is located at the notch of the accommodating groove 311, so as to limit the valve plate 33 from continuing to extend to the outside of the accommodating groove 311 under the action of the elastic member 32. Specifically, the outer ring of the limiting ring 34 is fixedly connected to the groove wall of the accommodating groove 311, and the inner ring diameter of the limiting ring 34 is smaller than the diameter of the valve plate 33. The limiting ring 34 is used to limit the valve plate 33. Further, a plurality of through holes 330 are provided on the valve plate 33, and the plurality of through holes 330 correspond to the end wall of the sleeve 30. When in use, water in the EDI device 1 enters the first pipe 21. Under the pressure of the water in the first pipe 21, the elastic member 32 and the valve plate 33 are popped open so that the valve plate 33 and the limit ring 34 are abutted against each other, thereby connecting the first pipe 21 with the second pipe 22. The water in the first pipe 21 enters the second pipe 22 through the through hole 330 and then flows out of the EDI device 1. In addition, when there is excessive pressure at the rear end of the second pipe 22 in the direction of the first pipe 21 and water hammer is about to form, the elastic member 32 is contracted under the pressure of the reverse water, and the valve plate 33 and the end wall of the sleeve 30 are abutted against each other. At this time, the through hole 330 is blocked by the end wall of the sleeve 30, thereby disconnecting the first pipe 21 from the second pipe 22, thereby cutting off the water flow and preventing the water flow from impacting the module in the front-end EDI device 1.
[0025] The guide rod 35 is fixedly arranged at the bottom of the fixing member 31, and the guide rod 35 is located between the first flange plate 23 and the second flange plate 24. The grounding column 36 is arranged on the side wall of the guide rod 35, and the grounding column 36 is located at one end of the guide rod 35 away from the fixing member 31, and the grounding column 36 is connected to the grounding wire. In this embodiment, the buffer assembly 3 is made of metal material. When static electricity accumulates in the EDI device 1 and generates a potential difference, the current enters the earth through the ground wire, thereby forming an effective grounding.
[0026] In this embodiment, the elastic member 32 is a spring. In other embodiments not shown, the elastic member 32 may also be an elastic and rigid element such as a stainless steel shrapnel or a copper shrapnel, which is not limited here.
[0027] Furthermore, a through groove 312 is formed on the bottom wall of the accommodating groove 311 , and the diameter of the through groove 312 is smaller than the diameter of the accommodating groove 311 , which can connect the fixing member 31 with the first pipe 21 on the one hand, and can install the elastic member 32 more stably on the other hand.
[0028] During operation, water in the EDI device 1 enters the first pipe 21. Under the pressure of the water in the first pipe 21, the elastic member 32 and the valve plate 33 are popped open so that the valve plate 33 and the limit ring 34 are abutted against each other, thereby connecting the first pipe 21 with the second pipe 22. The water in the first pipe 21 enters the second pipe 22 through the through hole 330 and then flows out of the EDI device 1. In addition, when the rear end of the second pipe 22 has excessive pressure in the direction of the first pipe 21 and is about to form a water hammer, under the pressure of the reverse water, the valve plate 33 and the end wall of the sleeve 30 are abutted against each other. At this time, the through hole 330 is blocked by the end wall of the sleeve 30, thereby disconnecting the first pipe 21 from the second pipe 22, thereby cutting off the water flow and preventing the water flow from impacting the modules in the front-end EDI device 1.
[0029] The pipeline grounding device for EDI equipment provided by the utility model can control the on-off of the water outlet pipe 2 by arranging a sleeve 30, an elastic member 32, a valve plate 33 and a limit ring 34, and the valve plate 33 can be movably arranged between the sleeve 30 and the limit ring 34, thereby eliminating the hidden danger of water hammer in the water outlet pipe 2. At the same time, a guide rod 35 and a grounding column 36 are arranged, so that when static electricity accumulates in the EDI equipment 1 and generates a potential difference, the current can enter the earth through the ground wire, thereby forming an effective grounding.
