[0032] Embodiment 1

[0033] Please refer to Figure 1-2, this embodiment introduces a high-reaction mixing device for refining and purifying crude rice bran oil, which mainly consists of a reaction tank body 1, a heating component 2, a water-cooling component 3, an air-flow component 4, and a temperature sensor 5. The reaction tank body 1 includes a tank body 11, an outer layer 12, a stirring member 13, and related control components. The tank body 11 is divided into a tank body and a tank cover. The outer layer 12 is located on the tank body and wraps the middle section to the bottom of the tank body, and the two form a chamber. The diameter of the bottom of the tank body gradually decreases and is conical, but a discharge pipeline communicating with the inside of the tank body is provided at the center of the bottom of the tank body, and a valve 111 is provided on the discharge pipeline. When the valve 111 is opened, the materials in the tank body can be discharged through the discharge pipeline. The outer layer 12 extends to the conical part at the bottom of the tank body but is located on the outer periphery of the discharge pipeline.

[0034] Brackets can be installed around the tank body for placing or installing other devices. The tank cover is detachably arranged on the top of the tank body. The stirring member 13 is arranged on the tank cover and penetrates the tank cover and extends into the tank body. The stirring member 13 mainly includes a motor 131, a stirring rod 132, a first stirring blade 133, and a second stirring blade 134. The motor 131 is installed at the center of the tank cover. The output shaft of the motor 131 penetrates the tank cover and is located below the tank cover. The output shaft of the motor 131 can be connected to the stirring rod 132 through a coupling. The first stirring blade 133 and the second stirring blade 134 are both fixedly arranged on the stirring rod 132. The first stirring blade 133 is located above the second stirring blade 134. The first stirring blade 133 contacts the inner wall of the tank body, and the situation of sticky materials on the inner wall of the tank body can also be reduced during the stirring process. The second stirring blade 134 is located at the conical part of the tank body and stirs the conical part of the tank body. The first stirring blade 133 and the second stirring blade 134 stir the materials to meet the requirements of processes such as acid refining / chemical decolorization in the process of refining and purifying crude rice bran oil.

[0035] The heating component 2 mainly consists of a heat-insulating water tank 21, an electric heating pipe 22, and a water pump 23. The heat-insulating water tank 21 and the water pump 23 can be installed on the brackets. The water inlet end of the heat-insulating water tank 21 is connected to the water supply pipeline, and the water outlet end is connected to the input end of the water pump 23 through a pipeline. The output end of the water pump 23 is communicated with the chamber. The electric heating pipe 22 is located in the heat-insulating water tank 21. When heating operation is required for the tank body 11, the electric heating pipe 22 is driven to work. After heating the water in the heat-insulating water tank 21 to the required temperature, the hot water is sent into the chamber by the water pump 23 to heat the tank body 11. The temperature sensor 5 can sense the temperature in the chamber. The bottom of the chamber has a drainage end, and the hot water can be discharged through the drainage end. The water pump 23 continuously inputs hot water, and the cooled hot water is discharged to keep the temperature of the tank body 11. The discharged cooled hot water can be returned to the heat-insulating water tank 21 or discharged to a designated position.

[0036] The water-cooling component 3 is mainly composed of a first water pump 31 and a water tank 32. The first water pump 31 and the water tank 32 can be installed on a bracket. The water inlet end of the water tank 32 is connected to a water supply pipeline, and the water outlet end is connected to the input end of the first water pump 31 through a pipeline. The input end of the first water pump 31 is communicated with the chamber. When cooling is required, the first water pump 31 inputs the cooling water in the water tank 32 into the chamber, and after the water cools down to the specified temperature, it is discharged from the chamber to a specified position.

[0037] Since both hot water and cold water need to be discharged from the chamber, two drainage ends can be provided at the bottom of the chamber to drain hot water and cold water respectively, or a drainage pipe 14 is provided at one drainage end, and the end of the drainage pipe 14 is connected to one end of a three-way valve 15, and the other two ends drain hot water and cold water respectively.

[0038] The air-flow component 4 is mainly composed of an air pump 41, an air pipe 42 and an electromagnetic valve 43. The air pump 41 can be installed on a bracket or on the tank cover. The output end of the air pump 41 is connected to the top end of the air pipe 42. The air pipe 42 is located inside the chamber, but both ends extend outside the chamber, so the air pipe 42 is not communicated with the chamber. Since there are multiple air pipes 42, the output end of the air pump 41 can be connected to the top end of the air pipe 42 through a branch or a pipe joint accessory, etc. The bottom end of the air pipe 42 can also be commonly connected to the electromagnetic valve 43 through a branch or a pipe joint accessory, etc. When the hot water is inside the chamber but needs to be cooled and the cooling range is not large, the external air flow can be introduced into the air pipe 42 by the air pump 41, the electromagnetic valve 43 is opened, and the air flow is discharged through the electromagnetic valve 43. Heat exchange is carried out through the flow of the air flow in the air pipe 42, and then the hot water in the chamber is cooled until the temperature drops to the required temperature.

[0039] In addition, in order to maintain the temperature of the hot water in the chamber, an electric heating tube 22 can also be installed in the chamber for heat preservation. The air flow is discharged through the electromagnetic valve 43, and the air pressure is relatively high, and the danger is great near the exhaust place. As Figure 3 shown, a shunt pipe 44 can be installed at the end of the electromagnetic valve 43. The shunt pipe 44 is linear, and a plurality of exhaust holes are provided on the surface of the shunt pipe 44. The directions of the exhaust holes face the direction where no staff is in contact, so as to shunt the air flow and reduce the air pressure.

[0040] The utility model meets the cooling requirements of the tank body 11 through the water-cooling component 3 and the air-flow component 4, can shorten the time required for cooling. When the cooling temperature difference is large, the water-cooling component 3 is adopted, and when the cooling temperature difference is small, the air-flow component 4 is adopted, so as to avoid the continuous high temperature from affecting the refining and purification effect.

The difference is that the shunt pipe 44 in this embodiment is arc-shaped and is distributed around the outer circumference of the tank body 11. This reduces the occupied space in a single direction, but increases the exhaust angle.
