It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0025] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: a bipolar membrane electrodialysis separator, comprising a device body 1, a processing mechanism 2 is arranged on the top of the device body 1;

[0026] The processing mechanism 2 includes two support plates 201 and six bent pipes 208. A shell 202 is fixed between the tops of the two support plates 201. A motor 203 is installed on one side of the shell 202. A rotating rod 204 is movably penetrated on one side of the shell 202. A baffle 205 is fixedly sleeved on the outer surface of the rotating rod 204. A sealing sleeve 206 is sleeved on the outer surface of the baffle 205. A discharge hole 207 is opened at the bottom position of the front surface of the inner wall of the shell 202. A sealing plate 209 is installed at the outlet of the discharge hole 207. A filter screen 210 is installed at the input end of the four bent pipes 208. One end of the rotating rod 204 is rotatably embedded in the inner wall of the shell 202. The outer wall of the sealing sleeve 206 is in contact with the inner wall of the shell 202. The input ends of the four bent pipes 208 They are fixed through the bottom of the shell 202, the output end of each elbow 208 is respectively connected to each liquid inlet end of the device body 1, the bottoms of the two support plates 201 are fixed to the top of the device body 1 near the front surface, the top of the shell 202 is installed with a top cover 3, and the input end of the other elbow 208 is installed with a sealing cover 4. Two symmetrical connecting plates 5 are fixed on the rear surface of the device body 1, and a protective shell 6 is arranged between the opposite sides of the two connecting plates 5. The front surface of the protective shell 6 is in contact with the rear surface of the device body 1. The top of one of the connecting plates 5 is movably penetrated by two symmetrical clamping rods 7, and the bottom ends of the two clamping rods 7 are movably penetrated through the top of the protective shell 6, and the bottom ends of the two clamping rods 7 are movably penetrated through the top of the other connecting plate 5.

[0027] In this embodiment, when it is necessary to treat the wastewater, the top cover 3 is first removed from the shell 202, and then the device body 1 is connected to an external power supply, and then all the sealing covers 4 are removed, and then the treated wastewater is introduced from the input ends of the two elbows 208 respectively. When a proper amount of wastewater is injected into the device body 1, the injection of wastewater is directly stopped, and then the removed sealing cover 4 is installed back to the initial position, and then a proper amount of water (seawater) is injected into the shell 202. At this time, the injected water will be first stored in the space composed of the inside of the shell 202 and the top of the sealing sleeve 206. When a proper amount of water is injected into the space, a suitable proportion of ion exchange resin particles are directly injected into the space. When the ion exchange resin particles complete the placement operation, the calcium and magnesium ions contained in the water can be adsorbed and removed under the action of the ion exchange resin particles. After the ion exchange resin particles are mixed with water for a period of time, the motor 203 is directly started. At this time, the started motor 203 will directly drive the rotating rod 204 connected thereto to rotate, and the rotating rotating rod 20 4 will drive the baffle plate 205 connected thereto to rotate, and the rotating baffle plate 205 will also drive the sealing sleeve 206 to rotate. When the sealing sleeve 206 rotates, the treated water in the above space and the mixed ion exchange resin particles will be guided to the bottom of the inner wall of the shell 202 together, and then the water guided to the bottom of the inner wall of the shell 202 will directly pass through the network card of the filter screen 210 and be diverted into the inside of the four elbows 208, while the ion exchange resin particles will directly remain in the inside of the shell 202. When all the wastewater is diverted to the inside of the curved pipe 208, the sealing plate 209 is directly removed, and the ion exchange resin particles left at the bottom of the shell 202 are quickly cleaned out using the prepared tools. The sealing plate 209 is then installed back to the original position, and then the top cover 3 is also installed back to the original position. The two clamping rods 7 are then pulled out from the top of one of the connecting plates 5, and then the protective shell 6 is taken out from between the two connecting plates 5. Finally, the device body 1 is opened, and the injected water is used to treat the injected wastewater.

[0028] Among them, the device body 1 is a bipolar membrane electrodialysis device, which is a device that uses bipolar membrane electrodialysis technology to separate electrolytes in a solution. The bipolar membrane is a new type of ion exchange composite membrane, which is usually composed of a cation exchange layer (N-type membrane), a bipolar membrane, a shell, a controller, a top plate, a liquid outlet pipe, a valve, a collection bucket and an anion exchange layer (P-type membrane). The working principle is to separate charged ions from aqueous solutions and other uncharged components using the reverse ion migration principle of the charged ion membrane under the action of a DC electric field. It is a membrane separation process driven by a potential difference, wherein the top of the device body 1 close to the positive surface position and the bottom of the two support plates 201 are fixed to the top plate.

[0029] Among them, the device body 1, the motor 203 and the filter 210 are all existing technologies, and their working principles are public technologies. Their models can be used according to actual conditions and will not be explained in detail here.

[0030] The working principle of this embodiment is as follows: when it is necessary to treat the wastewater, the top cover 3 is first removed from the shell 202, and then the device body 1 is connected to an external power supply, and then all the sealing covers 4 are removed, and then the treated wastewater is introduced from the input ends of the two elbows 208 respectively. When a proper amount of wastewater is injected into the device body 1, the injection of wastewater is directly stopped, and then the removed sealing cover 4 is installed back to the initial position, and then a proper amount of water (seawater) is injected into the shell 202. At this time, the injected water will be first stored in the space composed of the inside of the shell 202 and the top of the sealing sleeve 206. When a proper amount of water is injected into the space, a suitable proportion of ion exchange resin particles are directly injected into the space. When the ion exchange resin particles complete the placement operation, the calcium and magnesium ions contained in the water can be adsorbed and removed under the action of the ion exchange resin particles. After the ion exchange resin particles are mixed with water for a period of time, the motor 203 is directly started. At this time, the started motor 203 will directly drive the rotating rod 204 connected thereto to rotate, and the rotating rotating rod 2 04 will drive the baffle plate 205 connected thereto to rotate, and the rotating baffle plate 205 will also drive the sealing sleeve 206 to rotate. When the sealing sleeve 206 rotates, the treated water in the above space and the mixed ion exchange resin particles will be guided to the bottom of the inner wall of the shell 202 together. Subsequently, the water guided to the bottom of the inner wall of the shell 202 will directly pass through the network card of the filter screen 210 and be diverted into the inside of four elbows 208, while the ion exchange resin particles will directly remain in the inside of the shell 202. When the water inside the shell 202 When all the wastewater is diverted to the inside of the curved pipe 208, the sealing plate 209 is directly removed, and the ion exchange resin particles left at the bottom of the shell 202 are quickly cleaned out using the prepared tools. The sealing plate 209 is then installed back to the original position, and then the top cover 3 is also installed back to the original position. The two clamping rods 7 are then pulled out from the top of one of the connecting plates 5, and then the protective shell 6 is taken out from between the two connecting plates 5. Finally, the device body 1 is opened, and the injected water is used to treat the injected wastewater.
