Description

Technical Field

[0002] Biodiesel production equipment is a key device that converts animal and vegetable oils into clean fuels, reducing energy consumption and pollution, and achieving green production. This technology is of great significance in promoting the application of renewable energy.

[0003] After searching, the Chinese patent with announcement number CN214382703U discloses a biodiesel preparation device based on multi-stage distillation. In order to improve the efficiency of biodiesel preparation, the inner side of the preparation tank is provided with a mixing chamber, a steam chamber, and a heating chamber from top to bottom. The inner side of the mixing chamber is provided with a mixing mechanism, and the two sides of the steam chamber are symmetrically connected with exhaust mechanisms, and the inner side of the heating chamber is symmetrically fixed with heating pipes. The invention stirs the raw oil and the catalyst by the mixing mechanism in the mixing chamber, and replaces the traditional direct heating reaction preparation form under the stirring and heating of the heating pipe in the heating chamber. It not only improves the reaction completeness of the raw oil and the catalyst, but also improves the preparation efficiency of biodiesel. In the preparation process, the exhaust mechanism on both sides of the steam chamber adsorbs and purifies the steam generated by heating, which can prevent the steam from vaporizing into water droplets and falling into the biodiesel.

[0004] In the above-mentioned existing technical solution, the material inside the preparation tank is heated by a heating tube, and the moisture in the material evaporates and is discharged through the steam chamber, resulting in a lower temperature inside the mixing chamber located at the top of the preparation tank.

[0038] Step 2: The raw materials entering the preparation cylinder are filtered by the filter assembly and fall into the bottom of the preparation cylinder. The impurities retained on the top of the filter assembly slide along the side wall of the filter assembly and fall into the collection assembly.

[0039] Step 3: Start the heating rod to heat the raw materials and distill the raw materials. Start the driving motor to drive the driving rod to rotate. The driving rod stirs the raw materials at the bottom end of the preparation cylinder. As the driving rod rotates, the heat conducting component transports the water produced by distillation to the conduction component. The conduction component heats the raw materials on the top of the filter component and makes the raw materials on the top of the filter component flow, preventing the raw materials on the top of the filter component from agglomerating due to too low temperature.

[0040] Step 4: Remove the collecting assembly from the side wall of the preparation cylinder, discharge the impurities and distilled water inside the collecting assembly, pull out the sealing plug at the bottom of the preparation cylinder, discharge the processed raw materials, and complete the preparation of biodiesel.

[0041] Compared with the prior art, the present invention has the following significant advantages:

[0042] First, the present invention introduces the material to be processed into the interior of the preparation cylinder through the feed pipe on the cover plate, heats the material inside the preparation cylinder through the heating rod, and the moisture inside the material evaporates. The water vapor flows upward and condenses into water inside the gathering tank, and then enters the interior of the driving rod through the gathering tank and contacts the auger blades. Through the cooperation of the driving gear, the positioning shaft and the transmission belt, the driven shaft rotates in the opposite direction of the driving rod. The auger blades transport the hot water upward as the driven shaft rotates, and the interior of the stirring rod is connected with the interior of the driving rod and the positioning ring through the diversion groove, so that the auger blades can send hot water into the interior of the stirring rod, so that the stirring rod can evenly heat the material on the top of the filter assembly, and the hot water inside the stirring rod enters the interior of the positioning ring as the stirring rod rotates, avoiding the situation where the grease on the top of the preparation cylinder is agglomerated due to the low temperature; it solves the problem that the raw materials at the top of the existing preparation cylinder are solidified due to the low temperature.

[0043] Secondly, the present invention filters the material through a pair of filter plates, and the rotating plate rotates synchronously with the driving rod. The top rod lifts the contact block as the rotating plate rotates, causing the filter plate to vibrate continuously, thereby improving the filtering efficiency of the filter plate. Since the filter plate is arranged inclined, the impurities retained on one side wall of the filter plate are conveniently guided to the discharge hole and discharged outward through the discharge hole.

[0044] Third: The present invention can collect impurities on the top of filter plate one through the feed trough on the storage box, and filter the material again through filter plate two. The material inside the storage box can flow back to the inside of the preparation cylinder through the reflux trough. By utilizing the cooperation of the pull rod and the support spring, the filter plate two is lifted, so that there is a gap between the filter plate two and the bottom wall of the storage box, which facilitates the flow of materials. When impurities fall into the top of the filter plate two, the filter plate two will swing up and down under the influence of the elasticity of the support spring, which facilitates the filtering of the material by the filter plate two.

[0045] Fourthly, in the present invention, when the drain hole is aligned with the drain pipe, the water inside the positioning ring is discharged and guided into the water collecting tank through the drain pipe. Since the water diversion pipe runs through the interior of the storage box, the hot water flowing in the water diversion pipe will also heat the interior of the storage box, thereby preventing the temperature inside the storage box from being too low, which may cause grease to agglomerate inside the storage box.

The hot water inside the stirring rod 71 enters the interior of the positioning ring 73 as the stirring rod 71 rotates. When the drainage hole 75 is aligned with the drainage pipe 76, the water inside the positioning ring 73 is discharged and enters the interior of the water collecting tank 77 through the guidance of the drainage pipe 76. Since the water diversion pipe 78 runs through the interior of the storage box 51, the hot water flowing in the water diversion pipe 78 will also heat the interior of the storage box 51, avoiding the internal temperature of the storage box 51 being too low, which will cause the grease inside the storage box 51 to agglomerate.

[0068] Step 3: Start the heating rod 35 to heat the raw materials and perform distillation on the raw materials. Start the driving motor 31 to drive the driving rod 32 to rotate. The driving rod 32 stirs the raw materials at the bottom end of the preparation cylinder 1. As the driving rod 32 rotates, the heat conducting component transports the distilled water to the conduction component. The conduction component heats the raw materials at the top of the filter component, causing the raw materials at the top of the filter component to flow, thereby preventing the raw materials at the top of the filter component from agglomerating due to the low temperature. The distilled water is transported into the water collecting tank 52 through the conduction component, and the water collecting tank 52 collects the distilled water.

[0069] Step 4: Remove the collecting assembly from the side wall of the preparation cylinder 1, discharge the impurities and distilled water inside the collecting assembly, pull out the sealing plug at the bottom of the preparation cylinder 1, discharge the processed raw materials, and complete the preparation of biodiesel.
