[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0025] The following gives specific embodiments.

[0026] As Figures 1-5As shown, a chlorine recovery device includes a reaction tank 1; a gas transmission pipe 11 is installed in the middle of the reaction tank 1; a liquid inlet pipe 12 is fixedly connected to the outer wall of the reaction tank 1; a liquid outlet pipe 13 is fixedly connected to the bottom of the reaction tank 1; the end of the gas transmission pipe 11 is fixedly connected with an exhaust part 14, and the exhaust part 14 is arranged inside the reaction tank 1; two groups of spring rods 15 are fixedly connected to the inner wall of the reaction tank 1; the output end of the spring rod 15 is fixedly connected with a sliding plate 16, and the sliding plate 16 is slidably arranged on the inner wall of the reaction tank 1; two groups of top blocks 17 are fixedly connected to the inner wall of the reaction tank 1, and the top blocks 17 are arranged to match the shape of the end of the sliding plate 16; during operation, after the staff installs the reaction tank 1 in the designated working area, then continuously injects an appropriate amount of solution into the reaction tank 1 through the liquid inlet pipe 12 until the solution completely immerses the exhaust part 14. Then, the staff can connect the gas transmission pipe 11 to the external pipe for inputting chlorine gas, and under the action of air pressure, input the gas into the liquid, so that the gas is processed after passing through the liquid. At the same time, the processed gas will float upward and transfer its position through the hole opened in the middle of the reaction tank 1. When the liquid input into the reaction tank 1 through the liquid inlet pipe 12 reaches a certain level, under the action of the gravity of the liquid, the entire sliding plate 16 can slide downward until the side wall of the sliding plate 16 is separated from the two groups of top blocks 17. Then, the used part of the liquid on the top of the sliding plate 16 can be transferred to the bottom position of the sliding plate 16 through the gap and discharged through the liquid outlet pipe 13. When the amount of the liquid discharged from the top of the sliding plate 16 reaches a certain amount, when the elastic force of the two groups of spring rods 15 for resetting is greater than the liquid on the top of the sliding plate 16, the sliding plate 16 can be pulled upward again and reset. This step, combined with the sliding plate 16 that can move up and down, can replace the used part of the solution inside the reaction tank 1, reducing the problem of low efficiency in chlorine treatment that occurs when the gas transmission pipe 11 needs to be closed first during the replacement of the solution. At the same time, under the action of the exhaust part 14 and the small holes in the middle, the uniformity of transporting chlorine gas into the reaction tank 1 can be improved.

[0027] As Figures 2-4As shown in the figure, a fixed frame plate 2 is fixedly connected to the middle of the gas pipeline 11; multiple guide cylinders 21 are fixedly connected to the middle of the fixed frame plate 2, and the multiple guide cylinders 21 are arranged in a horn shape; a rotating rod 22 is rotatably connected to the inner wall of the guide cylinder 21; a rotating fan 23 is fixedly connected to the middle of the rotating rod 22; a connecting piece 24 is fixedly connected to the top of the rotating rod 22; two stirring rods 25 are fixedly connected to the top of the connecting piece 24; during operation, by arranging the fixed frame plate 2 in the middle of the gas pipeline 11, when the gas discharged from the middle of the exhaust part 14 moves upward, part of the gas will be position-guided by the horn-shaped guide cylinder 21, and in cooperation with the arranged rotating fan 23, the rotating rod 22 can rotate in the middle of the guide cylinder 21, and the two connecting pieces 24 arranged at the top of the rotating rod 22 will stir the liquid inside the reaction tank 1, and make the liquid and chlorine deeply fuse together. This step, in cooperation with the arranged rotatable stirring rods 25, can increase the reaction time between chlorine and the liquid, and at the same time can increase the distribution area of the gas inside the reaction tank 1, improve the precision when treating chlorine, and under the action of the horn-shaped guide cylinder 21, the dispersed bubbles can be centrally treated, and the stability of the rotating rod 22 during rotation can be improved.

[0028] As Figures 4-5 shown, two brackets 3 are fixedly connected to the side wall of the guide cylinder 21; two pull ropes 31 are fixedly connected to the middle of the rotating rod 22, and the pull ropes 31 are arranged through the middle of the brackets 3; an impact ball 32 is fixedly connected to the end of the pull rope 31; during operation, by arranging two brackets 3 at the end of the connecting piece 24, the brackets 3 can support the position of the pull rope 31, and during the rotation process of the rotating rod 22, driven by centrifugal force, the suspended pull rope 31 and the impact ball 32 can move, and the two impact balls 32 will gradually impact the middle position of the gas pipeline 11, and clean the caking crystals at the holes in the middle of the exhaust part 14 through the vibration force. This step, under the action of the impact ball 32, can improve the cleanliness of the surface of the exhaust part 14 during use, reduce the problem of more impurities at the holes of the exhaust part 14, and prevent the problem of low uniformity when discharging gas into it later, and under the action of the brackets 3, the position of the pull rope 31 can be limited and supported.

[0029] As Figures 3-4 shown, multiple reinforcing frames 4 are fixedly connected to the middle of the stirring rod 25; a filter screen 41 is fixedly connected to the inner wall of the reinforcing frame 4; during operation, by arranging multiple reinforcing frames 4 in the middle of the stirring rod 25, the reinforcing frames 4 can support the multiple filter screens 41, so that when the stirring rod 25 rotates as a whole, the water-permeable filter screen 41 can clean and collect some impurities in the liquid. This step, under the action of the filter screen 41, can improve the cleanliness of the liquid, further reduce the blockage problem of the middle of the exhaust part 14 by impurities, and at the same time the multiple reinforcing frames 4 can reinforce the position of the filter screen 41 and reduce the problem of its middle deformation.

[0030] As Figure 3 shown, a first magnet 5 is fixedly connected to the bottom of the exhaust member 14; a second magnet 51 is fixedly connected to the top of the sliding plate 16, and the second magnet 51 and the first magnet 5 are arranged to attract each other; during operation, by arranging the first magnet 5 at the bottom of the exhaust member 14, when the sliding plate 16 is reset, the second magnet 51 will approach the first magnet 5, and the two will adsorb and fix each other. This step, combined with the arranged first magnet 5 and second magnet 51, can reduce the problem that when there is less liquid on the top of the sliding plate 16, the output end of the spring rod 15 moves, resulting in a short separation time between the sliding plate 16 and the top block 17, and it is difficult to discharge an appropriate amount of used liquid.

[0031] As Figure 2 shown, a guide plate 6 is fixedly connected to the inner wall of the reaction tank 1, and the middle part of the guide plate 6 is inclined; the guide plate 6 is arranged close to the liquid outlet pipe 13; during operation, by arranging the guide plate 6 at the bottom of the reaction tank 1, and the liquid passes through the sliding plate 16 and transfers to its bottom position, the liquid will first contact the guide plate 6 and, by means of its inclined surface, transfer the liquid to the center. This step, under the action of the guide plate 6, can increase the speed of the liquid outlet pipe 13 to discharge the used liquid, and at the same time reduce the retention time of more liquid on the inner wall of the reaction tank 1.

[0032] As Figure 5 shown, a plurality of protective members 7 are fixedly connected to the inner wall of the bracket 3, and the plurality of protective members 7 are in contact with the pull rope 31; during operation, by arranging the protective members 7 on the inner wall of the bracket 3, when the pull rope 31 moves, the middle part of it will contact and work with the protective members 7. This step, under the action of the protective members 7, can protect the middle part of the pull rope 31 and increase the service life of the pull rope 31.

[0033] Working principle: After installing the reaction tank 1 in the designated working area, then continuously inject an appropriate amount of solution into the reaction tank 1 through the liquid inlet pipe 12 until the exhaust part 14 is completely soaked by the solution. Then, the staff can connect the gas transmission pipe 11 with the external pipe for inputting chlorine gas, and under the action of air pressure, input the gas into the liquid, so that the gas is processed after passing through the liquid. At the same time, the processed gas will float upward and transfer its position through the hole opened in the middle of the reaction tank 1. When the liquid input into the reaction tank 1 by the liquid inlet pipe 12 reaches a certain level, under the action of the gravity of the liquid, the whole slide plate 16 can slide downward until the side wall of the slide plate 16 is separated from the two top blocks 17, then the used part of the liquid on the top of the slide plate 16 can be transferred to the bottom position of the slide plate 16 through the gap and discharged through the liquid outlet pipe 13. When the amount of liquid discharged from the top of the slide plate 16 reaches a certain amount, when the elastic force of the two spring rods 15 for resetting is greater than the liquid on the top of the slide plate 16, the slide plate 16 can be pulled upward again and reset its position. By arranging a fixed frame plate 2 in the middle of the gas transmission pipe 11, when the gas discharged from the middle of the exhaust part 14 moves upward, part of the gas will be guided in position by the horn-shaped guide cylinder 21, and in cooperation with the arranged rotating fan 23, the rotating rod 22 can rotate in the middle of the guide cylinder 21. The two connecting parts 24 arranged at the top of the rotating rod 22 will stir the liquid inside the reaction tank 1 and make the liquid and chlorine gas deeply fuse together. By arranging two brackets 3 at the end of the connecting part 24, the brackets 3 can support the position of the pull rope 31. When the rotating rod 22 rotates, under the drive of centrifugal force, the suspended pull rope 31 and the impact balls 32 can move, and the two impact balls 32 will gradually impact the middle position of the gas transmission pipe 11, and clean the caked crystals at the hole in the middle of the exhaust part 14 through the vibration force. By arranging a plurality of reinforcing frames 4 in the middle of the stirring rod 25, the reinforcing frames 4 can support the plurality of filter meshes 41, so that when the whole stirring rod 25 rotates, the water-permeable filter meshes 41 can clean and collect some impurities in the liquid. By arranging a first magnet 5 at the bottom of the exhaust part 14, when the slide plate 16 is reset, the second magnet 51 will approach the first magnet 5, and the two will adsorb and fix. By arranging a guide plate 6 at the bottom of the reaction tank 1, and when the liquid passes through the slide plate 16 and transfers to its bottom position, the liquid will first contact the guide plate 6, and with the help of its inclined surface, the liquid can be centered and transferred. By arranging a protective part 7 on the inner wall of the bracket 3, when the pull rope 31 moves, the middle part of it will contact the protective part 7 for work.
