[0022] The present invention will be further described below with reference to the embodiments.

[0023] Please see Figure 1-5This utility model provides a purification device for hydrogenation and deoxygenation of oils, including an insulated box 1. A self-rotating purification chamber 2 is rotatably connected between the inner walls of the two ends of the insulated box 1. The purification chamber 2 has a columnar hollow structure. A first shaft cylinder 21 and a second shaft cylinder 22 are respectively fixedly embedded in the middle of the two end faces of the purification chamber 2. The first shaft cylinder 21 and the second shaft cylinder 22 are respectively rotatably connected to the adjacent inner walls of the insulated box 1.

[0024] Specifically, the rotational connection between the first shaft cylinder 21 and the second shaft cylinder 22 enables the purification chamber 2 to rotate under the action of the drive component 4. The rotation of the purification chamber 2 allows the oil raw materials to tumble fully during the heating process, ensuring uniform heating of the raw materials, thereby improving the purification efficiency and the purity of the oil. It is worth noting that the insulation box 1 is covered with heat insulation materials such as polyurethane foam and rock wool to ensure heat preservation.

[0025] Furthermore, a plurality of radiant heaters 6 are evenly distributed on the bottom wall of the heat-insulating box 1, and an arc-shaped groove 11 is provided at the bottom of the heat-insulating box 1. A plurality of recessed grooves 12 are evenly distributed on the arc-shaped groove 11. A radiant heater 6 is installed between the inner walls of both ends of the recessed groove 12, and a ceramic heat insulation sheet 13 that serves as a limiting element is installed between the groove wall of the recessed groove 12 and the radiant heater 6.

[0026] Specifically, the arc-shaped groove 11 can better adapt to the shape of the purification chamber 2, ensuring that the oil raw materials at the bottom of the purification chamber 2 are heated evenly, avoiding local overheating or underheating. The radiation heater 6 transfers heat to the bottom of the purification chamber 2 through radiation, thereby heating the oil raw materials. The ceramic heat insulation sheet 13, which is semi-enclosed around the radiation heater 6, can prevent excessive heat transfer to other parts of the insulation box 1, improving the utilization efficiency of thermal energy and avoiding adverse effects. It is worth noting that the radiation heater 6 is a heating device that transfers heat through radiation. It uses the radiation energy of electromagnetic waves (such as infrared rays) to heat objects without conducting heat through air or other media. It aims to achieve radiation heating. Therefore, this application does not limit the specific model of the radiation heater 6.

[0027] Furthermore, a stirring assembly 3 extending into the left end of the purification chamber 2 and a drive assembly 4 for driving the purification chamber 2 to rotate are installed on one side of the insulated box 1. The stirring assembly 3 includes a first motor 31 screwed to the outer wall of the left end of the insulated box 1. A stirring rod 32 is fixedly connected to the output end of the first motor 31. The stirring rod 32 extends into the purification chamber 2 after passing through the first shaft cylinder 21. Multiple connecting rings 33 are equidistantly arranged on the outer side of the part of the stirring rod 32 located inside the purification chamber 2. Stirring blades 34 are fixedly connected to both sides of the connecting rings 33.

[0028] Specifically, after the first motor 31 starts, its output end drives the stirring rod 32 to rotate. The rotation of the stirring rod 32 is transmitted to the stirring blade 34 through the connecting ring 33. During the rotation, the stirring blade 34 stirs the oil raw material in the purification chamber 2, so that it can be heated evenly during the heating process. Through the stirring of the stirring blade 34, impurities and moisture in the oil raw material can be separated more effectively, thereby improving the purification efficiency.

[0029] Furthermore, the drive assembly 4 includes a second motor 41 that is screwed to the outer wall of the left end of the insulation box 1. The output end of the second motor 41 is fixedly connected to a gear 42. The gear 42 is meshed with a gear ring 43. The gear ring 43 is fixed to the outer wall of the first shaft cylinder 21.

[0030] Specifically, after the second motor 41 starts, its output end drives the gear 42 to rotate. The gear 42 meshes with the gear ring 43, transmitting the rotational power to the gear ring 43. The gear ring 43 is fixed on the outer wall of the first shaft cylinder 21. Therefore, the rotation of the gear ring 43 drives the first shaft cylinder 21 to rotate, which in turn drives the purification chamber 2 to rotate. The rotation of the purification chamber 2 causes the oil raw materials in the purification chamber 2 to tumble continuously, ensuring that the raw materials are heated evenly during the heating process and accelerating the separation speed of impurities and moisture.

[0031] Furthermore, a tube bundle assembly 5 extending to the right end of the purification chamber 2 is installed on the other side of the insulation box 1. The tube bundle assembly 5 consists of a feed pipe 51, a steam exhaust pipe 52, and a discharge pipe 53. The feed pipe 51, the steam exhaust pipe 52, and the discharge pipe 53 are all fixedly embedded on the outer wall of the insulation box 1 opposite to the second shaft cylinder 22.

[0032] Specifically, the feed pipe 51, the exhaust pipe 52, and the discharge pipe 53 can communicate with the interior of the purification chamber 2 without affecting the rotation of the purification chamber 2. The oil raw material enters the bottom of the purification chamber 2 through the feed pipe 51, comes into contact with the radiation heater 6 and begins to be heated. During the heating process, the water in the oil evaporates into water vapor, and the water vapor is discharged from the purification chamber 2 through the exhaust pipe 52. After purification, the purified oil is extracted from the bottom of the purification chamber 2 through the discharge pipe 53.

[0033] Furthermore, the discharge pipe 53 extends downward at one end within the purification chamber 2, and the exhaust pipe 52 extends upward at one end within the purification chamber 2.

[0034] Specifically, during the purification process, the water in the oil evaporates into water vapor and is discharged, thereby improving the purity of the oil. The upward extension of the exhaust pipe 52 ensures that this water vapor can be discharged smoothly from the purification chamber 2, avoiding the accumulation of water vapor in the purification chamber 2, thereby reducing the pressure in the purification chamber 2. After the purification process is completed, the purified oil is extracted through the discharge pipe 53. The discharge pipe 53, which extends to the bottom of the purification chamber 2, can better collect the purified oil and reduce the discharge residue of the purified oil.

[0035] Working principle:

[0036] In operation, the raw oil is first poured into the purification chamber 2 through the feed pipe 51. The radiant heater 6 is then turned on to heat the bottom of the purification chamber 2, making the raw oil more evenly heated. The second motor 41 is then started, which drives the gear 42 to rotate. The gear 42 meshes with the gear ring 43, which in turn drives the gear ring 43 to rotate. The gear ring 43 drives the first shaft cylinder 21 and the purification chamber 2 to rotate, causing the raw material in the purification chamber 2 to tumble continuously. At the same time, the first motor 31 is started, which drives the stirring rod 32 to rotate. The stirring rod 32 drives the stirring blade 34 to continuously stir the tumbling raw material, ensuring that the raw oil is heated evenly. During the above process, the moisture in the raw oil evaporates into water vapor, which enters the filtration equipment through the exhaust pipe 52, thereby improving the purity of the oil. After the oil purification is completed, the purified oil can be extracted through the discharge pipe 53.
