Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor fall within the protection scope of the utility model.

[0016] Please refer to Figures 1-3 The utility model discloses a chemical wastewater distillation device, including distillation tank 2, the side of distillation tank 2 is equipped with heating jacket 4, and distillation tank 2 is equipped with water inlet pipe 1 and water outlet pipe 13, and water outlet pipe 13 is connected with condenser 14, and condenser 14 is connected with recovery tank 15, and the upper end of distillation tank 2 is installed with the cleaning mechanism for cleaning the inner wall of distillation tank 2 through lifting mechanism 12, when using, the chemical wastewater is sent into distillation tank 2 through water inlet pipe 1, is heated through heating jacket 4, and the chemical raw material in wastewater is evaporated into gas through water outlet pipe 13 into condenser 14, and is condensed into liquid after condenser 14 and is recovered into recovery tank 15, then starts lifting mechanism 12, and the inner wall of distillation tank 2 is cleaned by driving cleaning mechanism through lifting mechanism 12, and the above is prior art, and the principle can refer to the chemical wastewater distillation device disclosed in Chinese utility model patent CN218115046U.

[0017] The main innovation of the utility model lies in that: the cleaning mechanism includes:

[0018] Mounting seat 7, mounting seat 7 is fixed with lifting mechanism 12, can move up and down on the inner upper end of distillation tank 2.

[0019] The fixed ring 3 is fixed between the mounting base 7 through several fixed rods 8, and the center of the fixed ring 3 coincides with the center of the distillation tank 2, and the fixed ring 3 can move up and down in the inside of the distillation tank 2 under the driving of the lifting mechanism 12.

[0020] The hammer head 6 is arranged at the lower end of the fixed ring 3, and the hammer head 6 is connected with the mounting base 7 through a driving mechanism, which is used to drive the hammer head 6 to swing at the bottom of the fixed ring 3 and knock the inner wall of the distillation tank 2. Through the arrangement of the hammer head 6 and the driving mechanism, when the fixed ring 3 moves up and down in the inside of the distillation tank 2, the hammer head 6 can be driven to swing and repeatedly knock the inner wall of the distillation tank 2 through the driving mechanism, so that the crystals on the inner wall of the distillation tank 2 can be knocked off and more easily peeled off from the distillation tank 2.

[0021] The scraping ring 10 is in close contact with the inner wall of the distillation tank 2, and the scraping ring 10 is connected with the fixed ring 3 through a moving mechanism 9, which is used to drive the scraping ring 10 to move in the axial direction of the fixed ring 3, so that the scraping ring 10 can reach the position below the hammer head 6. When the fixed ring 3 moves in the inside of the distillation tank 2, the scraping ring 10 can be driven to move together. When cleaning, the fixed ring 3 moves downward to drive the hammer head 6 to move downward. During the moving process, the driving mechanism 12 drives the hammer head 6 to swing at the bottom of the fixed ring 3, and the hammer head 6 knocks the inner wall of the distillation tank 2 to knock off the crystals on the inner wall of the distillation tank 2. Then, the scraping ring 10 passes through the position knocked by the hammer head 6 to shovel off the knocked crystals. It can be understood that, since the hammer head 6 is arranged at the lower position, when the hammer head 6 knocks the bottom of the distillation tank 2, the scraping ring 10 is at the upper position of the hammer head 6, so that the lower end of the inner wall of the tank body cannot be shoveled. The moving mechanism 9 can drive the scraping ring 10 to move downward relative to the fixed ring 3, so that the scraping ring 10 can reach the position below the hammer head 6. In this way, the crystals at the lower end of the inner wall of the tank body can be shoveled off by the scraping ring 10.

When the swing rod 17 swings, the hammer head 6 swings to knock off the crystals on the inner wall of the distillation tank 2.

[0023] In order to prevent the knocking force of the hammer head 6 from being too large, the spring sheet 18 is fixed between the hammer head 6 and the swing rod 17.

[0024] In one embodiment of the present application, the driving mechanism comprises a telescopic cylinder 5 and a connecting rod 16, the upper end of the telescopic cylinder 5 is fixed with the mounting seat 7, the lower end of the telescopic cylinder 5 is fixed with a connecting block 19, the telescopic cylinder 15 drives the connecting block 19 to move up and down when telescoping, one end of the connecting rod 16 is rotatably connected with the connecting block 19, the other end of the connecting rod 16 is rotatably connected with the swing rod 17, the connecting block 19 moves up and down to drive the swing rod 17 to swing back and forth through the connecting rod 16.

[0025] The lower end of the distillation tank 2 is provided with a slag discharge port 11 for discharging slag after cleaning.

[0026] The number of hammer heads is at least six, and the hammer heads 6 are uniformly arranged around the center of the fixed ring.

[0027] In summary, the utility model aims at realizing a high-efficiency chemical wastewater distillation device. The device is innovated on the basis of the existing distillation technology, and a special cleaning mechanism is additionally arranged to solve the problem that thick crystals are easily formed on the inner wall of the distillation tank after distillation, and the crystals are difficult to be removed by the scraping structure and are easily damaged. The device comprises a mounting seat 7, a fixed ring 3, hammer heads 6 and a scraping ring 10, the hammer heads 6 are driven to swing at the bottom of the fixed ring 3 and knock the inner wall of the distillation tank 2 by the driving mechanism, so that the crystals on the inner wall of the distillation tank 2 can be knocked and broken, and are more easily peeled off from the distillation tank 2.
