This process filters the impurities in the cooling water without affecting the water cooling cycle, improves its cooling effect, and thus improves the working efficiency of the device.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1 , Figure 2 and Figure 3 The utility model provides an embodiment: a cooling circulation device for a high-temperature reactor, comprising a reactor 1, a water cooling box 3 is fixedly connected to the outside of the reactor 1, a circulation box 4 is fixedly connected to the front side of the water cooling box 3, a heating plate 5 is fixedly connected to the bottom of the inner wall of the circulation box 4, a heat dissipation pipe 6 is fixedly connected to the top of the inner wall of the circulation box 4, a ventilation hood 7 is arranged on the top of the circulation box 4, a fan 8 is connected to the top of the ventilation hood 7, an air pipe 9 is fixedly connected to the front side of the bottom of the inner wall of the reactor 1, and a positioning ring 10 is fixedly connected to the top of the outer wall of the air pipe 9, The top middle part of the air pipe 9 is connected with an air bag 11, the top of the inner wall of the positioning ring 10 is slidably connected with an indicator plate 12, a reserved hole 13 is opened on the left side of the front end of the outer wall of the circulation box 4, the front side of the indicator plate 12 passes through the reserved hole 13, a switch 14 is fixedly connected to the outside of the circulation box 4, a water pump 15 is connected to the left side of the circulation box 4, a water supply pipe 16 is connected to the output end of the water pump 15, a water return pipe 17 is connected to the right side of the circulation box 4, the rear sides of the water supply pipe 16 and the water return pipe 17 are both connected to the water cooling box 3, and a self-cleaning mechanism 2 is arranged on the inside of the water cooling box 3;

[0031] Specifically, by controlling the water temperature in the circulation box 4, the air pipe 9 is heated to shrink the airbag 11. This process pushes the indicator plate 12 to move along the reserved hole 13 and toggle the switch 14. When the temperature rises, the airbag 11 expands, pushing the indicator plate 12 to toggle the switch 14 upward, starting the fan 8 to dissipate the cooling water through the heat dissipation pipe 6. On the contrary, when the temperature drops, the airbag 11 shrinks, the indicator plate 12 moves downward, toggle the switch 14, start the heating plate 5 to heat the cooling water, and the cooling water enters the water cooling box 3 through the water pump 15 and the water adding pipe 16 to cool the reactor 1 and circulate through the return water pipe 17. In this process, the temperature of the cooling water can be controlled in real time to maximize the cooling effect.

[0032] Reference Figure 3 The self-cleaning mechanism 2 includes a rotating ring 201, which is rotatably connected to the top of the inner wall of the water-cooling box 3, and a plurality of water flow plates 202 are fixedly connected to the bottom of the rotating ring 201. A hollow ring 203 is fixedly connected to the outer side of the water flow plate 202, and a plurality of scrapers 204 are fixedly connected to the inner side of the hollow ring 203. The left and right sides of the bottom of the outer wall of the water-cooling box 3 are connected to the dust collecting box 205;

[0033] Specifically, water is added to the water cooling box 3 through the water supply pipe 16 and the water return pipe 17 is used to drain water, thereby ensuring smooth water flow inside the water cooling box 3. At the same time, the rotation of the rotating ring 201 and the water flow plate 202 is started. The special shape of the water flow plate 202 allows impurities in the cooling water to move along its outer wall to the hollow ring 203 and the bottom of the water cooling box 3, and be pushed by the scraper 204. When the pushed impurities move to the top of the dust collecting box 205 connected to the water cooling box 3, they will be collected therein. This process filters impurities in the cooling water without interfering with the water cooling cycle, thereby improving its cooling effect.

[0034] Reference Figure 1 , Figure 2 and Figure 3 The front and rear sides of the right end of the ventilation hood 7 are fixedly connected with hinges 23, and the ventilation hood 7 is rotatably connected to the circulation box 4 through the hinges 23; the middle part of the front end of the circulation box 4 is fixedly connected with a controller 18, and the controller 18 is electrically connected to the heating plate 5, the fan 8, the switch 14 and the water pump 15 respectively; the outer wall of the controller 18 is fixedly connected with a shell 19, and the outer side of the shell 19 is rotatably connected with a shield 20;

[0035] Specifically, the ventilation hood 7 can be opened and closed by the hinge 23 to facilitate maintenance and cleaning of the device. The starting and operating power between the heating plate 5, the fan 8, the switch 14 and the water pump 15 can be controlled respectively by the controller 18. The protection capability of the controller 18 can be improved by the casing 19. By opening and closing the protective cover 20, the controller 18 can be prevented from being accidentally touched when it is not in use.

[0036] Reference Figure 1 and Figure 3 The left and right sides of the bottom of the circulation box 4 are fixedly connected with brackets 26, and the rear side of the bracket 26 is fixedly connected to the reactor 1; the outer wall of the water cooling box 3 is fixedly connected with positioning blocks 24, and the outer sides of the plurality of positioning blocks 24 are provided with positioning holes 25; the front side of the outer wall of the circulation box 4 is provided with a plurality of temperature measuring grooves 22, and the front right side of the circulation box 4 is fixedly connected with a thermometer 21;

[0037] Specifically, the bracket 26 can improve the firmness of the fixation between the circulation box 4 and the reactor 1. By installing a threaded part in the positioning hole 25 on the positioning block 24, the device can be easily installed and fixed. The temperature measuring tank 22 can facilitate the detection and reading of the temperature of the thermometer 21.

[0038] Working principle: Before using the device, first heat the air pipe 9 through the water temperature in the circulation box 4, so that the air bag 11 shrinks to drive the indicator plate 12 to move along the reserved hole 13 and toggle the switch 14. When it is hot, the air bag 11 expands to drive the indicator plate 12 to flip the switch 14 upward, and the fan 8 is turned on to drive the air flow to dissipate the cooling water through the heat dissipation pipe 6. On the contrary, when the temperature drops, the air bag 11 shrinks to mobilize the indicator plate 12 to move downward to flip the switch 14 downward, so as to turn on the heating plate 5 to heat the cooling water. The cooling water will be sent into the water cooling box 3 through the water pump 15 and the water supply pipe 16 to cool the reactor 1, and circulate through the return water pipe 17, so that the temperature of the cooling water can be controlled and adjusted in real time. The influence on the cooling effect is reduced, thereby improving the practicality of the device, and by adding water to the water cooling box 3 through the water adding pipe 16 and draining water through the return pipe 17, the water flow inside the water cooling box 3 will flow, and at the same time drive the rotating ring 201 and the water flow plate 202 thereon to rotate. Through the shape of the water flow plate 202, impurities in the cooling water can be moved along its outer wall to the hollow ring 203 and the bottom of the water cooling box 3, and at the same time pushed by the scraper 204. When the pushed impurities move to the top of the dust collecting box 205 connected to the water cooling box 3, they will fall into the dust collecting box 205 for collection. While not affecting the water cooling cycle, the impurities in the cooling water can be filtered to improve its cooling effect, thereby improving the working efficiency of the device.
