Abstract

The invention provides an ultrafiltration reverse osmosis electrodeionization desalting water system, which belongs to the technical field of pure water treatment, and comprises a mounting rack, an EDI filter assembly, a control assembly and a water supply assembly, and also comprises a connecting mechanism, a buffer mechanism and an adjusting mechanism. Through the arrangement of the buffer mechanisms, when liquid enters the connecting pipes, the liquid can enter the corresponding channels, at the moment, the arc-shaped plates can make contact with water flow, the multiple arc-shaped plates at the bottom of the same connecting belt can be far away from one another under the action of the impact force and pressure of the water flow, then the bottoms of the channels are opened, the elastic layers are stretched, and in the process, the elastic layers are separated from one another. Due to the fact that water flow firstly makes contact with the arc-shaped plate and can be buffered through the arc-shaped plate and the elastic layer, impact force of the water flow can be reduced, the water flow can be prevented from making direct contact with the positive membrane and the negative membrane, the phenomenon that the positive membrane and the negative membrane are perforated due to too large impact force is prevented, and the service life of the positive membrane and the negative membrane is prolonged.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention provides a buffer mechanism so that when the liquid enters the connecting pipe, it can enter the corresponding channel. At this time, the arc plate will contact the water flow. Under the action of the impact force and pressure of the water flow, multiple arc plates at the bottom of the same connecting belt can be moved away from each other, so that the bottom of the channel is opened and the elastic layer is stretched until it contacts the outer side of the arc plate and the inner side of the sleeve. In this process, since the water flow contacts the arc plate first, it can be buffered by the arc plate and the elastic layer, and part of the potential energy of the water flow can be converted into the kinetic energy of the rotation of the arc plate, which can reduce the impact force of the water flow, avoid the water flow from directly contacting the positive membrane and the negative membrane, prevent the positive membrane and the negative membrane from being perforated due to excessive impact force, and improve the service life of the positive membrane and the negative membrane.

[0018] 2. The present invention arranges the conductive member and the conductive joint. When water enters the fresh water inlet and the concentrated water inlet, the liquid can enter the corresponding channel when entering the connecting pipe, so that the multiple arc plates at the bottom of the connecting belt can be moved away from each other, and the connecting rod can be pushed to move, which can drive the sleeve to move synchronously, and can drive the second moving rod to move in the direction close to the adapter, so that the positioning block can enter the corresponding positioning groove. When the positioning block is blocked by the adapter, the conductive member can correspond to the position of the conductive joint. At this time, the connecting rod will continue to move, so that the second slider can enter the corresponding extrusion groove, and the second extrusion rod can move in the second slide groove in the direction close to the adapter, so that the conductive member and the conductive joint can be energized, so that The electrode plates can work, and when no water flows into the fresh water inlet and the concentrated water inlet, the elastic layer is reset, so that the multiple arc plates at the bottom of the connecting belt are close to each other, driving the connecting rod to slide on the inner side of the sleeve, which will preferentially make the second slider re-enter the adjusting groove from the inside of the extrusion groove, and the second elastic member is elastically reset, driving the conductive member to move in a direction away from the conductive joint, so that the conductive member and the conductive joint are no longer energized, and the electrode plates stop working. The energization state of the electrode plates is controlled by the water inlet conditions of the fresh water inlet and the concentrated water inlet. When the water supply component fails to supply water, the electrode plates will stop working to avoid heating and deformation of the diaphragms and partitions close to the two poles of the EDI, thereby increasing the service life of the equipment.

[0019] 3. The present invention provides the first extrusion rod and the card slot. When water is introduced into the fresh water inlet and the concentrated water inlet, the liquid can enter the corresponding channel when entering the connecting pipe, so that the multiple arc plates at the bottom of the connecting belt can be moved away from each other, and the connecting rod can be pushed to move, which can drive the sleeve to move synchronously, and can drive the second moving rod to move in the direction close to the adapter, so that the first moving rod can move in the guide groove. When the positioning block is blocked by the adapter, the first extrusion rod can correspond to the position of the card slot, and the first slider can move from the corresponding adjusting groove into the corresponding extrusion groove. The inner wall of the extrusion groove can squeeze the first extrusion rod, so that the first extrusion rod drives the first moving plate to move in the first slide groove in the direction away from the sleeve, and the bottom end of the first extrusion rod can enter the interior of the card slot, which can further limit and fix the sleeve, so as to avoid the movement of the connecting rod driving the sleeve to move or shake when the water pressure becomes smaller, thereby improving the stability of electrical connection between the conductive member and the conductive joint.

[0029] The tops of the two connecting pipes 61 correspond to the fresh water inlet 26 and the concentrated water inlet 28 one by one and are connected.

[0030] like Figure 5 As shown, in a normal state, that is, when the EDI filter assembly 2 is working without water intake, the channel 66 is wide at the top and narrow at the bottom, that is, the inner diameter of the end close to the connecting pipe 61 is larger than the inner diameter of the end away from the connecting pipe 61, and the bottom of the connecting belt 63 is flexibly connected to the arc plate 64, so that the arc plate 64 can move at the bottom of the connecting pipe 61 while cooperating with the connecting belt 63 and the elastic layer 65 to form a sealed pipeline, so that the liquid entering the connecting pipe 61 can completely enter the channel 66.

[0032] Embodiment 2 On the basis of the above-mentioned embodiments, during the use of the EDI device, if the water supply component fails and cannot supply water, the EDI device will run without water, which will cause the diaphragm and partition close to the two poles of the EDI to heat up and deform, resulting in an increase in the EDI concentrated water pressure difference, resulting in a decrease in water quality and water quantity. In severe cases, the partition will be burned out and water leakage will occur, affecting the service life of the equipment.

[0033] See also Figures 4 to 12 The adjusting mechanism 7 includes connecting rods 71. The number of connecting rods 71 ​​is the same as the number of connecting tubes 61 and their positions correspond. Each connecting rod 71 is sealingly and slidably connected to the fixing member 51.

The prior art will not be described in detail. In actual use, the control component 3 is used to control the conductor joint 723 to be energized, and then the water supply component 4 is controlled to supply water.

[0038] The outer wall of one side of each connecting rod 71 close to the limiting plate 72 is provided with two symmetrically arranged adjustment grooves 729, and each adjustment groove 729 is provided with a connected extrusion groove 730 on the side away from the limiting plate 72. The connection between each adjustment groove 729 and the extrusion groove 730 is provided in a wedge-shaped surface, and the first slider 711 and the second slider 717 correspond to the two adjustment grooves 729 on the corresponding connecting rod 71 one by one, and the first slider 711 and the second slider 717 can move inside the corresponding adjustment groove 729; The two extrusion grooves 730 on the same connecting rod 71 are symmetrical to each other.

[0039] The two electrode plates 214 correspond to the two conductive members 720 one by one, and each electrode plate 214 is electrically connected to the corresponding conductive member 720. Each electrode plate 214 is electrically connected to the corresponding conductive member 720 by passing a cable through the corresponding through slot 728.

[0040] Under normal conditions, that is, when no water enters the EDI filter assembly 2, the first slider 711 and the second slider 717 are both inside the corresponding adjustment groove 729. At this time, the first slider 711 and the second slider 717 can clamp the connecting rod 71 under the action of the first elastic member 710 and the second elastic member 716. The movement of the connecting rod 71 can drive the ring 73 to move synchronously.

[0041] It should be noted that when water flows into the fresh water inlet 26 and the concentrated water inlet 28, the liquid can enter the corresponding channel 66 when entering the connecting pipe 61, so that the multiple arc plates 64 at the bottom of the connecting belt 63 can move away from each other, and the connecting rod 71 can be pushed to move, and the sleeve ring 73 can be driven to move synchronously, and the second moving rod 75 can be driven to move toward the direction close to the adapter 721, so that the positioning block 718 can enter the corresponding positioning groove 724. When the positioning block 718 is blocked by the adapter 721, the conductive member 72 0 can correspond to the position of the conductive joint 723. At this time, the connecting rod 71 will continue to move, so that the second slider 717 can move inside the adjusting groove 729, so that the second slider 717 can enter the corresponding extrusion groove 730. The inner wall of the extrusion groove 730 can squeeze the second slider 717, so that the second extrusion rod 714 can move in the second slide groove 712 toward the direction close to the adapter 721, and the second elastic member 716 can be stretched, so that the conductive member 720 can be inserted into the limiting groove 725, so that the conductive member 720 and the conductive joint 723 can be connected. 3 is energized, so that the electrode plate 214 is energized and works; when the fresh water inlet 26 and the concentrated water inlet 28 are not filled with water, the elastic layer 65 is reset, so that the multiple arc plates 64 at the bottom of the connecting belt 63 are close to each other, and the connecting rod 71 is preferentially driven to slide inside the ring 73, so that the second slider 717 re-enters the corresponding adjustment groove 729 from the inside of the extrusion groove 730, and the second elastic member 716 is elastically reset, driving the conductive member 720 to move in a direction away from the conductive joint 723, so that the conductive member 720 and the conductive joint 723 are in contact with each other. The head 723 is no longer energized, the electrode plate 214 stops working, and then the connecting rod 71 continues to move, and can drive the ring 73 to move synchronously through the limit plate 72, and can make the second moving rod 75 move in the direction away from the adapter 721. The power-on state of the electrode plate 214 is controlled by the water inlet conditions of the fresh water inlet 26 and the concentrated water inlet 28. When the water supply component 4 fails to supply water, the electrode plate 214 will stop working, avoiding the heating and deformation of the diaphragm and partition near the two poles of the EDI, thereby increasing the service life of the equipment.

[0042] Embodiment 3 On the basis of the above embodiment, when the electrode plate is energized and working, if the pressure of the water flow becomes smaller, the arc plate will move, which will drive the connecting rod to move. Since the second slider is inside the corresponding extrusion groove, it will generate friction with the inner wall of the extrusion groove. Under the influence of friction, the movement of the connecting rod may drive the ring to move or shake, which will affect the power-on state of the conductive part and the conductive joint.

[0043] See also Figures 8 to 12, each first moving rod 74 is provided with a first sliding groove 76 connected to the inner side of the collar 73, each first sliding groove 76 is fixedly connected to the inner side of the first limiting ring 77, each first limiting ring 77 is slidably connected to the inner side of the first extrusion rod 78, the outer wall of each first extrusion rod 78 is fixedly connected to a first moving plate 79 slidably connected to the inner wall of the corresponding first sliding groove 76, a first elastic member 710 is connected between the top of each first moving plate 79 and the bottom of the corresponding first limiting ring 77, and each first extrusion rod 78 is fixedly connected to a first slider 711 at one end close to the collar 73; The bottom inner wall of the accommodating groove 53 is provided with guide grooves 726 of the same number and corresponding positions as the positioning blocks 718, and the two first moving rods 74 correspond one-to-one to the two guide grooves 726. Each first moving rod 74 can move inside the corresponding guide groove 726. A clamping groove 727 is provided inside each guide groove 726, and the position of the clamping groove 727 corresponds one-to-one to the position of the guide groove 722.

[0044] In actual use, when water enters the fresh water inlet 26 and the concentrated water inlet 28, the liquid can enter the corresponding channel 66 from the connecting pipe 61, so that the multiple arc plates 64 at the bottom of the connecting belt 63 can move away from each other, and the connecting rod 71 can be pushed to move, and the ring 73 can be driven to move synchronously, and the second moving rod 75 can be driven to move in the direction close to the adapter 721, and the first moving rod 74 can be moved in the guide groove 726. When the positioning block 718 is blocked by the adapter 721, the conductive member 720 can correspond to the position of the conductive joint 723, and the first extrusion rod 78 can correspond to the position of the card slot 727. The connecting rod 71 continues to move, and the second slider 717 can move from the corresponding adjustment groove 729 into the corresponding extrusion groove 730, so that the conductive member 720 and the conductive joint 723 are energized, so that the electrode plate 214 is powered on, and at the same time, the first slider 711 can also move from the corresponding adjusting groove 729 into the corresponding extrusion groove 730. The inner wall of the extrusion groove 730 can squeeze the first slider 711, so that the first extrusion rod 78 drives the first movable plate 79 to move in the first slide groove 76 in the direction away from the ring 73, and stretches the first elastic member 710, so that the bottom end of the first extrusion rod 78 can enter the interior of the slot 727, and the ring 73 can be further limited and fixed to prevent the ring 73 from moving or shaking when the pressure of the water flow decreases, thereby improving the stability of the electrical connection between the conductive member 720 and the conductive joint 723. At this time, if the pressure of the water flow decreases, the second slider 717 and the first slider 711 can only move in the corresponding extrusion groove 730 due to the cooperation of the first extrusion rod 78 and the slot 727.

[0045] Only when no water enters the fresh water inlet 26 and the concentrated water inlet 28, can the elastic layer 65 be completely reset. During this process, the multiple arc plates 64 at the bottom of the connecting belt 63 approach each other, which will drive the connecting rod 71 to slide on the inside of the ring 73, and will preferentially allow the second slider 717 and the first slider 711 to re-enter the corresponding adjustment groove 729 from the inside of the extrusion groove 730. The second elastic member 716 elastically resets, driving the conductive member 720 to move in a direction away from the conductive joint 723, so that the conductive member 720 and the conductive joint 723 are no longer energized. At the same time, the first elastic member 710 resets, driving the first extrusion rod 78 out of the inside of the slot 727, and then the connecting rod 71 continues to move, so that it can drive the ring 73 to move synchronously through the limit plate 72, so that the electrode plate 214 can be powered off and stop working.

[0046] The present invention provides the first extrusion rod 78 and the card slot 727. When the fresh water inlet 26 and the concentrated water inlet 28 are filled with water, the liquid can enter the corresponding channel 66 when entering the connecting pipe 61, so that the multiple arc plates 64 at the bottom of the connecting belt 63 can be moved away from each other, and the connecting rod 71 can be pushed to move, and the sleeve ring 73 can be driven to move synchronously, and the second moving rod 75 can be driven to move in the direction close to the adapter 721, and the first moving rod 74 can be moved in the guide groove 726. When the positioning block 718 is blocked by the adapter 721, the first extrusion rod 78 can be engaged with the card slot 727. 27 corresponds to the position of the first slider 711 can move from the corresponding adjusting groove 729 into the corresponding extrusion groove 730, the inner wall of the extrusion groove 730 can squeeze the first extrusion rod 78, so that the first extrusion rod 78 drives the first movable plate 79 to move in the first slide groove 76 in the direction away from the ring 73, and the bottom end of the first extrusion rod 78 can enter the interior of the card slot 727, which can further limit and fix the ring 73 to avoid the movement or shaking of the connecting rod 71 and the ring 73 when the pressure of the water flow becomes smaller, thereby improving the stability of the electrical connection between the conductive member 720 and the conductive joint 723.
