DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0020] Embodiment 1:

[0021] Reference Figure 1 , Figure 2 and Figure 3 A reactor cooling device comprises a reaction tank 1, a condensation box 202, and a cylinder 2 fixedly connected to the outer wall of the reaction tank 1, wherein the reaction tank 1 is fixedly connected with a plurality of groups of heat sinks 201, each group of heat sinks 201 is provided with a plurality of heat sinks 201, one end of the heat sink 201 is located in the reaction tank 1, and the other end is located in the cylinder 2, the bottom side wall of the cylinder 2 is fixedly connected with a water inlet pipe 204, the top side wall of the cylinder 2 is fixedly connected with a water outlet pipe 205, and the water outlet pipe 205 is connected to the condensation box 202 Fixedly connected; a water pump 203 is fixedly mounted on the condensation tank 202, wherein the output end of the water pump 203 is fixedly connected to the water inlet pipe 204; a rotating ring 3 is rotatably connected to the cylinder 2, wherein a plurality of connecting rods 301 are equidistantly fixedly connected to the rotating ring 3, and a plurality of disturbance rods 302 are equidistantly fixedly connected to the connecting rods 301; a driving mechanism is arranged on the cylinder 2 and is used to drive the rotating ring 3 to rotate; a ventilation component is arranged on the cylinder 2 and is used to ventilate the cylinder 2 from bottom to top.

[0022] The driving mechanism includes a second motor 304, a gear 305 and a gear ring 303 fixedly mounted on the rotating ring 3, the gear ring 303 is meshedly connected with the gear 305, the gear 305 is fixedly mounted on the output end of the second motor 304, and the second motor 304 is fixedly connected to the cylinder 2.

[0023] The top inner wall of the reaction tank 1 is rotatably connected to a rotating shaft 103, to which a lever 104 is fixedly connected. The top of the reaction tank 1 is fixedly connected to a motor 102, and one end of the rotating shaft 103 passes through the top of the reaction tank 1 and is fixedly connected to the output end of the motor 102.

[0024] A feeding port is provided on the top of the reaction tank 1;

[0025] When in use, the material for producing sodium triazole is poured into the reaction tank 1 through the feeding port for reaction, and then the motor 102 is started, the motor 102 drives the rotating shaft 103 to rotate, and the rotating shaft 103 drives the lever 104 to rotate, so that the rotating lever 104 stirs and mixes the material, thereby increasing the reaction speed of the material;

[0026] When the material is completely reacted, the heat inside the reaction tank 1 is conducted out through the heat sink 201, so that the heat inside the reaction tank 1 is reduced, thereby cooling the material in the reaction tank 1, and starting the water pump 203, the water pump 203 sucks the coolant in the condensation tank 202 and transports it into the cylinder 2 through the water inlet pipe 204. When the cylinder 2 is full of coolant, the coolant inside the cylinder 2 flows back into the condensation tank 202 through the water outlet pipe 205, thereby realizing the circulation of the coolant inside the condensation tank 202 inside the cylinder 2. The coolant is made to circulate inside the cylinder 2, thereby absorbing the heat inside the reaction tank 1, so as to cool the material in the reaction tank 1. At the same time, the second motor 304 is started, and the second motor 304 is connected to the gear ring 303 through the gear 305 to drive the rotating ring 3 to rotate. At the same time, the rotating ring 3 drives the connecting rod 301 and the disturbance rod 302 to rotate synchronously, so as to stir and mix the hotter coolant in the upper and middle layers of the cylinder 2 and the colder coolant in the lower layer, thereby improving the cooling effect of the coolant circulating inside the cylinder 2 on the material;

[0027] It should be additionally explained that a refrigeration fin is disposed in the condensation box 202 , so that the refrigeration fin is used to cool the coolant flowing back into the condensation box 202 .

[0028] Embodiment 2:

[0029] Reference Figure 1 , Figure 3 , a reaction kettle cooling device, which is basically the same as Example 1, and further, the ventilation component includes an air suction pump 4, the air suction pump 4 is fixedly connected to the cylinder 2, a hollow cavity 402 is opened at the bottom of the cylinder 2, and an air nozzle 403 connected to the hollow cavity 402 is fixedly installed on the bottom inner wall of the cylinder 2, and the output end of the air suction pump 4 is fixedly connected to the hollow cavity 402 through a pipeline 401, and a one-way valve is provided on the pipeline 401;

[0030] This embodiment is a second method for cooling the material in the reaction tank 1 after the reaction is completed. The heat inside the reaction tank 1 is extracted through the heat sink 201, so that the heat inside the reaction tank 1 is reduced, thereby cooling the material in the reaction tank 1. Then, the suction pump 4 is started, and the suction pump 4 absorbs external gas and transports it into the hollow cavity 402 through the pipeline 401. Finally, the gas is ejected through the air nozzle 403, so that the gas introduced into the cylinder 2 is dispersed from bottom to top, thereby cooling the heat sink 201. At the same time, the motor 2 304 is started, and the motor 2 304 is meshed and connected with the gear ring 303 through the gear 305 to drive the rotating ring 3 to rotate. At the same time, the rotating ring 3 drives the connecting rod 301 and the disturbance rod 302 to rotate synchronously, thereby disturbing the gas introduced into the cylinder 2, so that the gas is fully in contact with the heat sink 201, improving the heat dissipation and cooling effect of the heat sink 201, and then helping the heat sink 201 to better extract the heat inside the reaction tank 1, thereby improving the cooling effect of the material in the reaction tank 1.

[0031] The two methods of cooling the material in the reaction tank 1 in Example 1 and Example 2 can also be used in combination, so that when the gas introduced into the cylinder 2 drifts from bottom to top, it can cool the coolant retained in the cylinder 2, and at the same time, the rotating connecting rod 301 and the disturbance rod 302 can stir and mix the coolant and the gas, so that the gas can fully absorb the heat of the coolant, thereby improving the effect of the coolant retained in the cylinder 2 on cooling the material in the reaction tank 1;

[0032] It should be noted that an activated carbon filter (not shown in the figure) is provided at the input end of the air pump 4. When the air pump 4 absorbs external gas and transports it into the hollow cavity 402 through the pipeline 401, the gas passing through the input end of the air pump 4 contacts with the activated carbon filter. Since the activated carbon has a developed void structure and rich microporous tissue inside, these microporous tissues have a strong adsorption force field. When the gas contacts the activated carbon, the strong adsorption force field of the activated carbon micropores can adsorb the particulate matter in the air into the micropores, thereby achieving the effect of purifying the gas.

[0033] Embodiment 3:

[0034] Reference Figure 1 , a reactor cooling device, which is basically the same as Example 1, and further, the bottom of the reaction tank 1 is set in a conical shape; the bottom of the reaction tank 1 is fixedly connected to a discharge pipe 101, and a valve switch is set on the discharge pipe 101;

[0035] After the reaction and cooling of the material are completed, the valve switch on the discharge pipe 101 is opened so that the material can be discharged from the reaction tank 1 through the discharge pipe 101. At the same time, since the bottom inner wall of the reaction tank 1 is conical, the material can be completely discharged from the reaction tank 1 during the discharge process, thereby reducing material waste.

[0036] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention.
