Detailed Embodiment

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1 - 3 , the present utility model provides a technical solution: a movable modular electrodialysis device for the solvent purification field, including a bottom plate 1, on which a water tank 2, a filter box 5, an operation unit 15 and a desalination unit 16 are slidably arranged. Four sliding grooves are opened on the bottom plate 1, and the four sliding grooves are in a square shape. The bottoms of the water tank 2, the filter box 5, the operation unit 15 and the desalination unit 16 are fixedly provided with sliders 18, and the sliders 18 are slidably connected to the corresponding sliding grooves.

[0020] One side of the water tank 2 is fixedly provided with a first water pump 3, the output end of the first water pump 3 is communicated with the filter box 5 through a first telescopic pipe 4, the filter box 5 is fixedly provided with a second water pump 12 communicated with its interior, the output end of the second water pump 12 is communicated with the operation unit 15 through a second telescopic pipe 13, the operation unit 15 is communicated with the desalination unit 16 through a third telescopic pipe 14, and the desalination unit 16 is communicated with the water tank 2 through a fourth telescopic pipe 19. A drain port communicated with its interior is arranged at the bottom of the water tank 2, and the water in the water tank 2 can be discharged through the drain port.

[0021] A filter 10 and a heat exchanger 11 are detachably arranged in a filter box 5. Limiting grooves are symmetrically formed inside the filter box 5. A pull rod 6 is horizontally slidably arranged in the limiting grooves. One end of the pull rod 6 passes through the filter box 5 and is fixedly provided with a handle. Through grooves are symmetrically formed at the top of the filter box 5. A moving plate 9 is vertically slidably arranged in the through grooves. Limiting grooves are respectively formed on both sides of the moving plate 9. The other end of the pull rod 6 is fixedly provided with a clamping block 8, and the clamping block 8 is adapted to the corresponding limiting groove. A spring 7 is fixedly arranged between the clamping block 8 and the filter box 5, and the spring 7 is sleeved on the pull rod 6. The bottom of the moving plate 9 is respectively connected to the filter 10 and the heat exchanger 11. Grooves allowing the bottoms of the filter 10 and the heat exchanger 11 to be inserted are symmetrically formed at the bottom inside the filter box 5 to position the filter 10 and the heat exchanger 11. A handle is fixedly arranged at the top of the moving plate 9 to facilitate pulling up the moving plate 9.

[0022] One end of the clamping block 8 close to the moving plate 9 is a hemispherical surface. When the moving plate 9 is inserted into the through groove on the filter box 5, the hemispherical surface of the clamping block 8 is in sliding fit with the moving plate 9, so that the clamping block 8 can be retracted into the corresponding limiting groove. When the clamping block 8 is aligned with the corresponding limiting groove, the clamping block 8 is driven into the corresponding limiting groove under the restoring force of the spring 7, thereby realizing the limitation of the moving plate 9.

[0023] A flow regulating component is arranged in an operation unit 15. The flow regulating component is an electric control valve, and the electric control valve is respectively communicated with a second telescopic pipe 13 and a third telescopic pipe 14. A reverse osmosis membrane is fixedly arranged in a desalination unit 16 to effectively remove salts in water.

[0024] An electric control unit 17 is fixedly arranged at the center of the top of a bottom plate 1. A power cabinet and a PLC control cabinet are arranged in the electric control unit 17. The power cabinet and the PLC control cabinet are electrically connected. The PLC control cabinet is respectively electrically connected with a first water pump 3, a heat exchanger 11, a second water pump 12 and an electric control valve.

[0025] The working principle of a movable modular electrodialysis device for the solvent purification field provided by the utility model is as follows:

[0026] During use, the first water pump 3 is started through the electric control unit 17. The first water pump 3 pumps external sewage into the filter box 5 through a first telescopic pipe 4. After the sewage is preliminarily filtered by the filter 10, the temperature of the water is controlled to a suitable temperature through the heat exchanger 11, providing a basis for the long-term, safe and stable operation of the device. The second water pump 12 is started through the electric control unit 17. The second water pump 12 pumps the water in the filter box 5 into the desalination unit 16. After the reverse osmosis membrane in the desalination unit 16 desalinates the water, the flow of the water can be controlled by controlling the electric control valve in the operation unit 15. Finally, the sewage enters the water tank 2 for storage after desalination.

[0027] When the filter 10 and the heat exchanger 11 need to be replaced, pull the pull rod 6 outwards to make the clamping block 8 disengage from the limiting groove in the moving plate 9, and then pull the moving plate 9 upwards through the handle, so as to take out the filter 10 and the heat exchanger 11. Then, align the new filter 10 and heat exchanger 11 with the through groove of the filter box 5, and move the moving plate 9 downwards. The moving plate 9 is in sliding fit with the hemispherical surface of the clamping block 8, which can make the clamping block 8 retract into the corresponding limiting groove and compress the spring 7. When the clamping block 8 is aligned with the corresponding limiting groove again, the clamping block 8 is driven into the corresponding limiting groove under the restoring force of the spring 7, so as to limit the moving plate 9.

[0028] When the equipment needs to be repaired or the accessories need to be replaced, the water tank 2, the filter box 5, the operation unit 15 and the desalination unit 16 can be slid on the bottom plate 1 respectively. At the same time, the first telescopic pipe 4, the second telescopic pipe 13, the third telescopic pipe 14 and the fourth telescopic pipe 19 extend or shorten to change the distance between the water tank 2, the filter box 5, the operation unit 15 and the desalination unit 16, which is convenient for the maintenance personnel to enter. Thus, the limitation of the internal space of the container is eliminated, which is convenient for the disassembly, replacement and repair of the internal components, and greatly improves the operation efficiency of the equipment.

[0029] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
