[0038] The following reference Figures 1 to 3 The present application describes the electro-desalination apparatus and water treatment equipment according to embodiments thereof.

[0039] See Figures 1 to 3As shown, an embodiment of this application provides an electro-desalination device, including: an electro-desalination module (not shown in the figure), a junction box 2, a power supply 3, and a cover plate 5. The electro-desalination module is an existing, mature electro-desalination device, the principle and structure of which are fully understood by those skilled in the art. The process of electro-desalination to prepare pure water is not described in detail here. The electro-desalination module includes an end plate 1, an anode plate, and a cathode plate (not shown in the figure), and also includes a tail plate (not shown in the figure). The end plate 1 and the tail plate are arranged facing each other, and the anode plate and the cathode plate are disposed between the end plate 1 and the tail plate. The surface of the end plate 1 facing the tail plate is defined as the inner wall surface, and the surface of the end plate 1 facing away from the tail plate is the outer wall surface. The junction box 2 is disposed on the outer wall surface of the end plate 1. Preferably, the junction box 2 is disposed in the middle position of the end plate 1. The power supply 3 is located inside the junction box 2, which has an opening. The cover 5 is detachably installed in the opening of the junction box 2. The cathode plate and the anode plate are electrically connected to the power supply 3, so that the power supply 3 can supply power to the cathode plate and the anode plate, ensuring that the electro-deionization module can operate normally.

[0040] Specifically, power supply 3 includes a positive output terminal and a negative output terminal. The positive output terminal is electrically connected to the anode plate, and the negative output terminal is electrically connected to the cathode plate.

[0041] Furthermore, this electro-deionization device also includes a power controller 4, which is electrically connected to the power supply 3, enabling the power supply 3 to receive voltage and current input and to supply power to the positive and negative plates. The power controller 4 is electrically or communicatively connected to the main control system of the water treatment equipment, allowing the main control system to control the operating parameters of the power supply 3 through the power controller 4. It should be noted that the power controller 4 is a commonly used electronic component in this field and can be a common programmable PCB.

[0042] Optionally, the power supply 3 is provided with a first connection port, and the power controller 4 is provided with a second connection port for connecting to the first connection port. The first connection port and the second connection port are detachably connected by a connecting cable, so that the connection between the power supply 3 and the power controller 4 is detachable. This makes the power supply 3 and the power controller 4 adopt a non-integrated design, which makes replacement and disassembly convenient. The power supply 3, the electro-deionization module, etc. can be replaced and repaired without shutting down the entire water treatment equipment.

[0043] Furthermore, the junction box 2 includes a bottom wall and side walls. Preferably, the bottom wall is a rectangular flat plate, the length of which extends along the height direction of the end plate 1, and the bottom wall is fixedly disposed on the end plate 1. The side walls are annular, and the side walls are disposed along the edge of the bottom wall, such that the axis of the side walls is collinear with or parallel to the axis of the end plate 1. The port of the side wall away from the bottom wall forms an opening for installing the power supply 3 and the power controller 4. Optionally, the bottom wall is part of the outer wall surface of the end plate 1, that is, the annular side wall of the junction box 2 can be directly disposed on the outer wall surface of the end plate 1.

[0044] Furthermore, the bottom wall is provided with a first mounting part and a second mounting part, wherein the first mounting part is used to install the power supply 3 and the second mounting part is used to install the power controller 4.

[0045] Optionally, the first mounting part can be a groove provided on the bottom wall of the junction box 2. The inner wall of the first mounting part is provided with internal threads, and there are multiple first mounting parts, which are spaced apart. The outer casing of the power supply 3 is provided with multiple connection holes. The number of connection holes is the same as the number of first mounting parts and they are set one by one. The power supply 3 can be fixed in the junction box 2 by using screws to pass through the connection holes and threadedly connect with the first mounting parts.

[0046] Optionally, the second mounting part can be a groove provided on the bottom wall of the junction box 2. There are multiple second mounting parts, which are spaced apart. The inner wall of the second mounting part is provided with internal threads. The power controller 4 includes a housing. The housing of the power controller 4 is provided with a connection hole corresponding to the position of the second mounting part. The power controller 4 can be fixed in the junction box 2 by using screws to pass through the connection hole and connect to the second mounting part.

[0047] Furthermore, in Figure 1 In the state shown, which is also the state in which the junction box 2 is fixed to the end plate 1, the junction box 2 has a top edge and a bottom edge distributed in the vertical direction. The bottom edge of the junction box 2 is provided with a first wire hole 6, a second wire hole 7 and a third wire hole 8 at intervals along its length. Each wire hole penetrates the inner and outer walls of the bottom edge.

[0048] Furthermore, this electrostatic desalination device also includes a first power supply cable and a second power supply cable (not shown in the figure). One end of the first power supply cable is electrically connected to the external power supply 3, and the other end of the first power supply cable passes through the first wire hole 6 and is connected to the power controller 4. One end of the second power supply cable is electrically connected to the external power supply 3, and the other end of the second power supply cable passes through the second wire hole 7 and is connected to the power supply 3.

[0049] Furthermore, this electro-desalination device also includes a communication cable (not shown in the figure). The communication cable can be a network cable. One end of the communication cable is connected to the main control system of the water treatment equipment, and the other end of the communication cable passes through the third wire hole 8 and is connected to the power controller 4, so that the main control system and the power controller 4 can communicate and transmit signals.

[0050] Furthermore, the junction box 2 is provided with a plurality of first connecting parts 201. The first connecting parts 201 are cylindrical and their length extends along the depth of the junction box 2. Preferably, in this embodiment, the number of first connecting parts 201 is four. The four first connecting parts 201 are distributed at the four top corners of the junction box 2. The inner wall surface of the first connecting parts 201 is provided with internal threads.

[0051] Furthermore, the cover plate 5 is provided with a plurality of second connecting parts 501. The second connecting parts 501 have a hole structure. The number of second connecting parts 501 is the same as the number of first connecting parts 201 and they are arranged one-to-one. The four second connecting parts 501 are distributed at the four top corners of the cover plate 5. By using screws to thread the second connecting parts 501 and the first connecting parts 201, the cover plate 5 can be detachably installed in the opening of the junction box 2.

[0052] Furthermore, the electro-deionization device also includes a panel 9, which is disposed on the outer wall of the cover plate 5, and the panel 9 has through holes for passing cables through, and the panel 9 is connected to the power controller 4 using connecting cables.

[0053] Optionally, panel 9 includes a display screen that can display information such as the power supply status of power supply 3 to the cathode plate and anode plate.

[0054] Optionally, panel 9 includes multiple indicator lights, which can have various colors to reflect the power supply status of power supply 3 to the electro-deionization module.

[0055] In summary, the electro-desalination device provided in this application integrates the power supply 3 with the electro-desalination module, and can be optionally equipped with a power controller 4, allowing the electro-desalination device to be controlled independently without the need for external controller coordination. This effectively reduces abnormal situations such as signal delay and power loss. It can also operate independently and produce water independently, without needing to be connected to the main control system or other operating systems of water treatment equipment, making it suitable for a wide range of applications and highly flexible.

[0056] The embodiments of this application also provide a water treatment device, including the electro-desalination device described in any of the above embodiments, and thus have all the beneficial technical effects of the electro-desalination device, which will not be repeated here.

[0057] The water treatment equipment includes multiple electro-desalination devices and a central control system. Specifically, the central control system is a PLC with an integrated touchscreen, commonly used in the water treatment equipment field. The power controller 4 of each electro-desalination device is connected to the central control system for integrated control operation. Simultaneously, the operating status of the electro-desalination module can be fed back to the PLC in real time for dynamic parameter adjustment. The operation of each electro-desalination device is independent, allowing for individual maintenance and repair. The number of electro-desalination devices can also be appropriately increased or decreased according to needs, significantly expanding the scalability of this water treatment equipment.

[0058] In addition, the operating status of all electrostatic desalination units can be displayed and controlled via a touch screen, unifying the human-machine interface and reducing the number of openings in the control cabinet for the central control system.
