[0034] Embodiment 1: In some embodiments, please refer to Figures 1 - 6 in the accompanying drawings of the specification, a production crystallization device capable of preventing adhesion, including a body 1,

[0035] A reaction device 2 for reaction crystallization is installed on the body 1, and a flushing device 3 for cleaning the inside of the reaction device 2 and a feeding device 4 for conveying and discharging crystals are installed on the reaction device 2;

[0036] The reaction device 2 includes a crystallization assembly 21 for accommodating a crystallization solution, a scraping wall assembly 23 for preventing the inner wall of the crystallization assembly 21 from sticking, and a driving assembly 22 for driving the scraping wall assembly 23 to operate.

By driving the scraping wall assembly 23 to continuously scrape the inner side of the crystallization assembly 21 with the driving assembly 22, the problem of crystallization adhesion is avoided, and at the same time, the already crystallized crystals can be transported away, which can accelerate the crystallization rate of the remaining solution.

The inner diameter of the left crystallization tank 211 is larger than that of the right crystallization tank 211. The right crystallization tank 211 is located at the upper right of the left crystallization tank 211.

The feeding door 212 is located at the upper outer side of the left crystallization tank 211. One end of the feeding door 212 is rotatably connected to the crystallization tank 211. A through hole for cooperating with the feeding door 212 is opened on the crystallization tank 211. The crystallization tank 211 is connected to the driving assembly 22, the scraping wall assembly 23, the flushing device 3, and the feeding device 4.

[0040] The crystallization tank 211 is inclined, and the inclination direction of the crystallization tank 211 is gradually decreasing from the rear to the front.

[0041] The driving assembly 22 includes a motor 221, a motor frame 222 and a pulley assembly 223. The pulley assembly 223 consists of two synchronous pulleys and a belt. The two synchronous pulleys of the pulley assembly 223 are respectively rotatably connected to the rear ends of the two crystallization tanks 211. The motor 221 is fixedly connected to the rear end of the motor frame 222. The motor frame 222 is fixedly installed at the rear end of the left crystallization tank 211.

Connecting frames 232 are evenly and fixedly installed on the outer side of the rotating shaft 231. Scraping plates 233 are fixedly installed on the outer sides of the connecting frames 232.

When the scraping plate 233 is located at the connection of the two crystallization tanks 211, the left end of the scraping plate 233 is higher than the right end.

[0044] When the production crystallization device capable of preventing adhesion is in normal use, the motor 221 and the external cooler 12 are started. The external cooler 12 cools the crystallization tanks 211, causing the solution inside the crystallization tanks 211 to start crystallizing. The motor 221 drives the left synchronous pulley of the pulley assembly 223 to rotate. The right synchronous pulley is driven to rotate through the belt of the pulley assembly 223. The two synchronous pulleys drive the two rotating shafts 231 to rotate. The rotating shafts 231 drive the connecting frames 232 to rotate.

At the same time, the scraping plate 233 inside the left crystallization tank 211 rotates to convey the crystals into the right crystallization tank 211. The through holes on the scraping plate 233 can prevent the uncrystallized solution from being conveyed synchronously.

At the same time, the scraping plate 233 can also convey the crystals from the left crystallization tank 211 to the right crystallization tank 211 and then to the blanking device 4, reducing the crystal content in the solution and accelerating the crystallization rate.

[0045] The flushing device 3 includes a water inlet pipe 31, a plurality of spray nozzles 32, two water outlets 33 and two water outlet valves 34.

The two water outlets 33 are respectively fixedly connected to the lower front sides of the two crystallization tanks 211, and two water outlet valves 34 are respectively fixedly installed on the two water outlets 33.

[0046] When the production crystallization device that can prevent adhesion is in normal use, the water outlet valve 34 is opened, and the flushing device conveys water flow to the water inlet pipe 31 and sprays it onto the scraper 233 in the two crystallization tanks 211 along the spray nozzles 32. The flushing sewage is discharged through the water outlet 33. The arrangement of the spray nozzles 32 enables the crystallization tank 211 to be cleaned after crystallization is completed, avoiding adverse effects on the next crystallization caused by residues inside the crystallization tank 211.

[0047] The blanking device 4 includes a blanking chute 41 and a return chute 42. The blanking chute 41 is fixedly installed at the upper right side of the right crystallization tank 211.

[0048] The right crystallization tank 211 is provided with a through hole for discharging materials corresponding to the blanking chute 41. The lower end of the blanking chute 41 is provided with a through hole for filtering the solution. The right crystallization tank 211 is provided with a plurality of through holes for solution reflux corresponding to the return chute 42. The lower end of the return chute 42 is inclined, and the inclination direction is gradually decreasing from right to left.

[0049] When the production crystallization device that can prevent adhesion is in normal use, the scraper 233 in the right crystallization tank 211 rotates to convey the crystals to the blanking chute 41, and the solution therein flows into the return chute 42 through the through hole below the blanking chute 41 and returns to the right crystallization tank 211 along the return chute 42.
