DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0027] In one embodiment, Figure 1-Figure 7 As shown, an electrodialysis device with an electrode reversal structure includes a base 1 and an electrodialysis device body 2, universal wheels 3 are installed at the four corners of the bottom of the electrodialysis device body 2, and the universal wheels 3 are located on the top of the base 1, a filtering mechanism 5 is provided on one side of the outside of the electrodialysis device body 2, and a first electrode connection block 4 is symmetrically fixedly installed on the other side of the outside of the electrodialysis device body 2, guardrails 6 are fixedly installed on both sides of the top of the base 1, an electrode reversal mechanism 7 is provided between the outer sides of the two guardrails 6, and a positioning structure 8 is symmetrically provided on the top of the base 1, and the positioning structure 8 is located on both sides of the outside of the electrodialysis device body 2.

[0028] In this embodiment, the electrodialysis equipment body 2 is an electrodialysis equipment, which is an existing mature equipment and will not be described in detail here. The electrodialysis equipment body 2 is effectively fixed on the top of the base 1 through the positioning structure 8, thereby improving the working stability of the electrodialysis equipment body 2. The sewage can be effectively filtered and treated through the filtering mechanism 5 to prevent impurities from entering the electrodialysis equipment body 2 and causing clogging of the ion membrane and affecting the dialysis effect. At the same time, it is convenient to remove the filtered impurities from the inside of the filtering mechanism 5 for easy cleaning. The electrode of the electrodialysis equipment body 2 can be changed through the electrode reversing mechanism 7. The cathode solution is alkaline after long-term use and is easy to adhere to scale, while the anode solution is acidic and is easy to corrode the electrode. Therefore, it is necessary to reverse the electrode to achieve a comprehensive acid-base reaction, reduce scale, and extend the service life of the electrode.

[0029] In one embodiment, Figure 2 and Figure 6 As shown, the electrode switching mechanism 7 includes two fixed plates 701, and the two fixed plates 701 are respectively fixedly installed on one side of the two guardrails 6, and a first screw rod 702 is rotatably installed between the two fixed plates 701, and a first motor 703 is fixedly installed on one side of one of the fixed plates 701, and the output end of the first motor 703 is connected to the first screw rod 702, and the external thread of the first screw rod 702 is connected to two moving blocks 704, and a sliding rod 705 is fixedly installed between the two fixed plates 701, and the sliding rod 705 is located above the first screw rod 702, and the moving block 704 and the sliding rod 705 are slidably installed, and a first hydraulic cylinder 706 is fixedly installed on the external side of the moving block 704, and an adjusting plate 707 is fixedly installed on the output end of the first hydraulic cylinder 706, and a symmetrical fixed plate 707 is fixedly installed on the external side of the adjusting plate 707. The second electrode connection block 708 is adapted to the first electrode connection block 4, and the second electrode connection block 708 is electrically connected to the wire 709. The second electrode connection blocks 708 of the two adjustment plates 707 are opposite. When the electrode needs to be changed, the first hydraulic cylinder 706 contracts to drive the adjustment plate 707 to move, and the adjustment plate 707 moves to separate the second electrode connection block 708 from the first electrode connection block 4. At this time, the first motor 703 works to drive the first screw rod 702 to rotate, and the rotation of the first screw rod 702 drives the two moving blocks 704 to move together. When the second electrode connection block 708 of the other adjustment plate 707 is aligned with the first electrode connection block 4, the first motor 703 stops rotating, and the first hydraulic cylinder 706 works to extend to drive the adjustment plate 707 to move, so that the second electrode connection block 708 is inserted into the first electrode connection block 4 to complete the electrode switching.

[0030] In one embodiment, Figure 3As shown, the filtering mechanism 5 includes a filtering box 501, which is fixedly mounted on one side of the electrodialysis device body 2, and the filter box 501 is provided with slide grooves 503 on both sides thereof, and a collecting box 504 is slidably mounted on the inside of the filtering box 501 through the slide grooves 503, and a handle 505 is fixedly mounted on one side of the collecting box 504, and a sealing cover 506 is fixedly mounted on the top of the filtering box 501, and a water inlet pipe 502 is fixedly mounted on one side of the outside of the filtering box 501, and a water inlet pipe 502 is provided on the outside of the filtering box 501, and a water inlet pipe 502 is provided on the outside of the filtering box 501, and a water inlet pipe 502 is provided on the inside ... The sewage is introduced into the interior of the filter box 501. A filter hole is opened on one side of the collection box 504. Impurities in the sewage are effectively filtered through the filter hole. The impurities fall into the interior of the collection box 504 due to gravity. A sealing gasket is provided between the sealing cover 506 and the filter box 501 to ensure the sealing between the sealing cover 506 and the filter box 501. After using it for a period of time, the impurities inside the collection box 504 need to be cleaned. At this time, the sealing cover 506 is removed, and the collection box 504 is taken out by the handle 505 to facilitate the cleaning of the impurities.

[0031] In one embodiment, Figure 4 As shown, the positioning structure 8 includes a fixing frame 801, and the fixing frame 801 is fixedly installed on the top of the base 1. A threaded screw 802 passes through the top of the fixing frame 801. A crank 804 is connected to the top of the screw 802. A lower pressure plate 803 is rotatably installed on the bottom of the screw 802. After the electrodialysis equipment body 2 moves to the top of the base 1, it needs to be fixed. By turning the crank 804, the screw 802 is effectively driven to rotate. The rotation of the screw 802 changes the height of the lower pressure plate 803, so that the lower pressure plate 803 moves downward and fits with the electrodialysis equipment body 2, thereby fixing the electrodialysis equipment body 2.

[0032] In one embodiment, Figure 4 As shown, limit rods 805 are fixedly installed on both sides of the top of the lower pressing plate 803, and the limit rods 805 and the fixing frame 801 are slidably installed. The setting of the limit rods 805 improves the stability of the upper and lower movements of the lower pressing plate 803.

[0033] In one embodiment, Figure 4 and Figure 5 As shown, a positioning groove 13 is provided on the outside of the electrodialysis equipment body 2, and a positioning block 806 is fixedly installed on the bottom of the lower pressure plate 803, and the positioning block 806 is adapted to the positioning groove 13. The lower pressure plate 803 moves downward so that the positioning block 806 enters the interior of the positioning groove 13, which effectively positions and fixes the electrodialysis equipment body 2 and improves the working stability of the electrodialysis equipment body 2.

[0034] In one embodiment, Figure 6As shown, a mounting groove 9 is provided at the bottom of the base 1, and a second screw rod 10 is rotatably installed inside the mounting groove 9. A second motor 11 is fixedly installed on one side of the outside of the base 1, and the output end of the second motor 11 is connected to the second screw rod 10, so that the second motor 11 can effectively drive the second screw rod 10 to rotate.

[0035] In one embodiment, Figure 1 As shown, a mounting mechanism 12 is disposed outside the second screw rod 10 , and the second screw rod 10 rotates to change the position of the mounting mechanism 12 .

[0036] In one embodiment, Figure 7 As shown, the mounting mechanism 12 includes a moving seat 1201, the moving seat 1201 and the second screw rod 10 are threadedly connected, a rotating plate 1202 is rotatably mounted on one side of the moving seat 1201, and a second mounting seat 1205 is symmetrically fixedly mounted on the bottom of the rotating plate 1202, and a second hydraulic cylinder 1204 is rotatably mounted inside the two second mounting seats 1205, and a first mounting seat 1203 is rotatably mounted on one end of the two second hydraulic cylinders 1204, and the first mounting seat 1203 and the moving seat 1201 are fixedly mounted. It is necessary to move the electrodialysis equipment body 2 When it moves to the top of the base 1, the second motor 11 works to drive the second screw rod 10 to rotate, so that the moving seat 1201 moves, and the second hydraulic cylinder 1204 contracts to drive the rotating plate 1202 to rotate downward, so that one end of the rotating plate 1202 contacts the ground. At this time, it is convenient to push the electrodialysis equipment body 2 to the top of the rotating plate 1202. Hold the electrodialysis equipment body 2 with your hand, and the second hydraulic cylinder 1204 extends to drive the rotating plate 1202 to rotate upward to a horizontal position. The rotating plate 1202 adjusts the electrodialysis equipment body 2 to a horizontal position. At this time, it is convenient to push the electrodialysis equipment body 2 to the top of the base 1.

[0037] In one embodiment, Figure 1 As shown, support rods 14 are fixedly installed at the four corners of the bottom of the base 1, and the support rods 14 effectively support the base 1.

[0038] The working principle of the present invention is: when the electrodialysis equipment body 2 needs to be moved to the top of the base 1, the second motor 11 works to drive the second screw rod 10 to rotate, so that the movable seat 1201 moves, and the second hydraulic cylinder 1204 contracts to drive the rotating plate 1202 to rotate downward, so that one end of the rotating plate 1202 contacts the ground. At this time, it is convenient to push the electrodialysis equipment body 2 to the top of the rotating plate 1202. Hold the electrodialysis equipment body 2 with your hand, and the second hydraulic cylinder 1204 extends to drive the rotating plate 1202 to rotate upward to a horizontal position. The rotating plate 1202 adjusts the electrodialysis equipment body 2 to a horizontal position. At this time, it is convenient to push the electrodialysis equipment body 2 to the top of the base 1.

[0039] After the electrodialysis equipment body 2 moves to the top of the base 1, it needs to be fixed. By turning the crank 804, the screw 802 is effectively driven to rotate. The rotation of the screw 802 changes the height of the lower pressure plate 803, so that the lower pressure plate 803 moves downward and fits the electrodialysis equipment body 2. The lower pressure plate 803 moves downward so that the positioning block 806 enters the interior of the positioning groove 13, which effectively positions and fixes the electrodialysis equipment body 2, thereby improving the working stability of the electrodialysis equipment body 2.

[0040] The electrodialysis equipment body 2 is an electrodialysis equipment, which is an existing mature equipment for sewage treatment. No further details will be given here. The second electrode connection blocks 708 of the two adjustment plates 707 are opposite. When the electrode needs to be changed, the first hydraulic cylinder 706 contracts to drive the adjustment plate 707 to move. The adjustment plate 707 moves to separate the second electrode connection block 708 from the first electrode connection block 4. At this time, the first motor 703 works to drive the first screw rod 702 to rotate. The rotation of the first screw rod 702 drives the two moving blocks 704 to move together. When the second electrode connection block 708 of the other adjustment plate 707 is aligned with the first electrode connection block 4, the first motor 703 stops rotating, and the first hydraulic cylinder 706 works to extend to drive the adjustment plate 707 to move, so that the second electrode connection block 708 is inserted into the first electrode connection block 4 to complete the electrode switching.

Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application.
