[0002] Biodiesel refers to a renewable diesel fuel that can replace petrochemical diesel, which is made from oil crops such as soybeans, rapeseed, cotton, palm, etc., wild oil plants, aquatic plant oils such as engineering microalgae, animal fats, and kitchen waste oils as raw material oils through esterification, transesterification or thermochemical processes. The reaction conditions of the enzyme-catalyzed reaction production process are relatively mild, there are basically no requirements for the quality of the raw material oils, and the reaction products are easy to separate; at the same time, the enzyme catalyst usually used for the transesterification reaction of raw material oils and alcohols is lipase, which is rich in nature. Therefore, the process of preparing biodiesel by enzyme-catalyzed reaction has been more and more widely used. In the process of preparing biodiesel by enzyme-catalyzed reaction, it is usually necessary to fully mix the enzyme catalyst with the raw materials.

[0030] The following is combined with Figures 1 - 4 to describe the enzyme-catalyzed biodiesel reactor of the present invention.

[0031] As Figure 1 , Figure 2 and Figure 4 shown, in one embodiment, an enzyme-catalyzed biodiesel reactor includes a reaction barrel 100, bevel gears 200, a first support member 300, a stirring paddle 400 and a power member 500.

[0032] The reaction tank 100 is provided with a raw material pipe 110, an enzyme catalyst pipe 120, a first discharge pipe 130 and a second discharge pipe 140. The first discharge pipe 130 is located at the bottom of the reaction tank 100 and is convenient for discharging the glycerol generated after the reaction. The second discharge pipe 140 is located on the side wall of the reaction tank 100 and is convenient for discharging the biodiesel generated after the reaction. Shut-off valves are installed on both the first discharge pipe 130 and the second discharge pipe 140.

[0033] The bevel gear 200 is located inside the reaction tank 100, and the bevel gear 200 has a support shaft 210. The support shaft 210 is fixed to the reaction tank 100, and the bevel gear 200 and the support shaft 210 are coaxial.

[0034] The first support member 300 is rotatably connected inside the reaction tank 100.

[0035] The stirring paddles 400 are symmetrically located inside the reaction tank 100, and the stirring paddles 400 have a first rotating shaft 410 and a first gear 420. The first rotating shaft 410 is rotatably connected to the first support member 300, the first gear 420 is fixed to the first rotating shaft 410, and the first gear 420 is meshed and connected to the bevel gear 200.

[0036] The power member 500 is installed on the reaction tank 100, and the power member 500 is used to drive the first support member 300 to rotate around the support shaft 210 as the center.

[0037] In this embodiment, the power member 500 includes a motor 510, a second gear 520, a third gear 530 and a support pipe 540. The motor 510 is installed on the surface of the reaction tank 100, the second gear 520 is fixed to the output end of the motor 510, the support pipe 540 is rotatably connected to the inner wall of the reaction tank 100, the support pipe 540 is fixed to the first support member 300, the third gear 530 is fixed to the outer wall of the support pipe 540, and the third gear 530 is meshed and connected to the second gear 520.

[0038] It should be added that the support shaft 210 passes through the support pipe 540, and the support shaft 210 and the support pipe 540 are coaxial.

[0039] When the above enzyme-catalyzed biodiesel preparation reactor is in use, first, the raw materials and the enzyme catalyst are respectively added into the reaction barrel 100 from the raw material pipe 110 and the enzyme catalyst pipe 120. Then, the motor 510 is started to drive the second gear 520 to rotate. The second gear 520 drives the third gear 530 to rotate. The third gear 530 drives the support pipe 540 to rotate. The support pipe 540 drives the first support member 300 to rotate around the support shaft 210, so that the first gear 420 meshes and rotates on the outer wall of the bevel gear 200. During this process, on the one hand, the two stirring paddles 400 revolve around the support shaft 210. On the other hand, the two stirring paddles 400 rotate around their respective first rotating shafts 410, so that the rotation directions of the two stirring paddles 400 are different, which is convenient for fully stirring various materials and improves the full mixing efficiency of the raw materials and the enzyme catalyst.

[0040] It should be added that the included angle between the axis of the first rotating shaft 410 and the axis of the support shaft 210 is an acute angle, so that the two stirring paddles 400 can rotate without interfering with each other during the rotation process.

[0041] As Figure 3 shown, in one embodiment, the stirring paddle 400 includes a cross plate 430, a first inclined plate 440 and a second inclined plate 450. The cross plate 430 is fixed to the first rotating shaft 410, and the cross plate 430 is perpendicular to the first rotating shaft 410. The first inclined plate 440 is fixed to one side of the cross plate 430, and the second inclined plate 450 is fixed to the other side of the cross plate 430. The inclination directions of the first inclined plate 440 and the second inclined plate 450 are opposite.

[0042] The first inclined plate 440 and the second inclined plate 450 with the inclined direction on the cross plate 430 can improve the formation of eddy currents in the fluid near the cross plate 430, so that the raw materials and the enzyme catalyst are mixed more evenly and the biodiesel preparation efficiency is improved.

[0043] In this embodiment, the side walls of the first support member 300 are symmetrically and fixedly connected with second support members 310. The free ends of the second support members 310 are fixedly connected with scraping plates 330. The scraping plates 330 are in contact with the inner wall of the reaction barrel 100, which can effectively prevent glycerol or biodiesel from adhering to the inner wall of the reaction barrel 100.

[0044] In this embodiment, the second support member 310 has a bending angle 320, and the bending angle 320 is a right angle, so that the free end of the second support member 310 is connected to the middle of the scraping plate 330, which is convenient for the scraping plate 330 to receive force evenly and improves the service life of the scraping plate 330.

[0045] In this embodiment, refer to Figure 1, the reaction tank 100 has a hollow cavity 150. A heater 170 is installed on the outer wall of the reaction tank 100. The output end of the heater 170 is fixedly connected to a heating wire 160. The heating wire 160 is spirally wound inside the hollow cavity 150. A temperature sensor 180 is fixedly connected to the inner wall of the reaction tank 100. Through the cooperation between the heater 170 and the temperature sensor 180, it is convenient to control the preparation temperature of biodiesel, integrating the mixing reaction of raw materials and enzyme catalysts with extraction, and improving the preparation efficiency of biodiesel.

[0046] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0047] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation to the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
