Technical Field

[0001] This utility model relates to the field of biodiesel preparation technology, specifically a biodiesel preparation device. Background Technology

[0002] A biodiesel production unit is a specialized equipment system used to convert biomass raw materials (such as animal and vegetable oils, waste oils, etc.) into biodiesel.

[0003] Existing biodiesel production equipment often suffers from problems during production. The raw materials for biodiesel typically contain food residues, plastics, and fibrous solids, which can hinder the transesterification reaction and easily damage the equipment. Furthermore, during the production process, the reactants may stratify or exhibit localized concentration gradients due to density differences or high viscosity, making it difficult to guarantee the uniformity, rate, and quality of the final product. Therefore, improvements are needed. Utility Model Content

[0004] In view of the shortcomings of the prior art, the present invention provides a biodiesel preparation device, which has the advantages of improving the purity of biodiesel, ensuring uniform distribution of reactants, and improving reaction efficiency, thus solving the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a biodiesel preparation device, including a support frame, a top plate fixedly installed on the top of the support frame, a filter separation component provided on the top of the top plate, an installation frame fixedly installed on the outer wall of the support frame, a sliding groove provided on the inner walls of both sides of the top of the installation frame, a pulley slidably connected to the inner wall of the sliding groove, one end of a connecting rod fixedly mounted on the outer wall of the pulley, a limit ring fixedly mounted on the other end of the connecting rod, a stirring component provided at the bottom of the sliding groove, and a controller fixedly mounted on the outer wall of the installation frame.

[0006] As a preferred technical solution of this utility model: the number of connecting rods and pulleys is four, and the four connecting rods and pulleys are evenly and symmetrically distributed on the outer wall of the limiting ring. The diameter of the pulleys is adapted to the width of the groove. The bottom of the support frame and the mounting bracket are both made of natural rubber.

[0007] As a preferred technical solution of this utility model: the filtration and separation assembly includes a servo motor, the power output shaft of the servo motor is fixedly equipped with a drive wheel, one end of a transmission belt is drivenly connected to the outer wall of the drive wheel, and the other end of the transmission belt is drivenly connected to a driven wheel, a mounting column is fixedly installed on the top of the driven wheel, one end of a connecting plate is sleeved on the outer wall of the mounting column, and the other end of the connecting plate is installed on the top of the filter shell by fixing bolts, and a filter plate is snapped into the bottom of the inner wall of the filter shell.

[0008] As a preferred technical solution of this utility model: the servo motor and the controller are electrically connected, and the servo motor is fixedly installed at the bottom of the top plate. The diameter of the driving wheel is smaller than the diameter of the driven wheel. The cross-section of the filter shell is trapezoidal, and the outer wall of the filter shell is sleeved on the inner wall of the limiting ring.

[0009] As a preferred technical solution of this utility model: the stirring assembly includes a stirring drum, a fixing plate is fixedly installed on the inner wall of the stirring drum, a dual-shaft drive motor is fixedly installed on the outer wall of the fixing plate, a threaded rod is fixedly assembled on the power output shaft of the dual-shaft drive motor, one end of the stirring rod is fixedly installed on the outer wall of the threaded rod, and a scraper is fixedly assembled on the other end of the stirring rod. A filter layer is overlapped on the top of the stirring drum, and the top of the filter layer is respectively provided with mounting holes and filter holes.

[0010] As a preferred technical solution of this utility model: the dual-axis drive motor and the controller are electrically connected; there are two threaded rods with opposite threads; the stirring rod and the scraper are evenly distributed on the outer wall of the threaded rods; the outer wall of the scraper is in contact with the inner wall of the stirring cylinder; and the diameter of the mounting hole is adapted to the threaded rod.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. This biodiesel preparation device, through a signal emitted by the controller, can start the servo motor, enabling the drive wheel to rotate. This, in turn, drives the driven wheel to rotate synchronously via a transmission belt. The mounting column, through the connecting plate, causes the filter shell to reciprocate within the inner wall of the limiting ring. This allows the filter plate to quickly filter solid impurities such as food residue, plastic, and fibers from the biodiesel feedstock, retaining them on the inner wall of the filter shell. Other feedstocks fall onto the inner wall of the mixing drum, effectively removing these solid impurities and ensuring the smooth progress of the reaction. Furthermore, by removing impurities and moisture from the biodiesel feedstock, the viscosity of the feedstock is reduced, resulting in more uniform mixing and thus improving the purity of the biodiesel.

[0012] 2. This biodiesel preparation device, through a controller signal, can start a dual-shaft drive motor, which in turn drives the threaded rods at both ends to rotate in two directions. This, in turn, drives the stirring rod to stir the diesel feedstock on the inner wall of the stirring drum, resulting in good stirring effect and promoting uniform heat distribution on the inner wall of the stirring drum. This avoids local overheating or undercooling, maintains a stable reaction temperature, thereby improving reaction efficiency, increasing contact area, enhancing mass transfer rate, and making the reaction more efficient. At the same time, it can prevent the biodiesel feedstock from stratifying or exhibiting local concentration gradients due to density differences or high viscosity, thus ensuring uniform distribution of reactants, increasing reaction rate, and reducing the occurrence of side reactions by uniformly mixing reactants. This also avoids the generation of unnecessary impurities and ensures the quality of biodiesel preparation. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1 - Figure 5 A biodiesel production apparatus includes a support frame 1, a top plate 3 fixedly installed on the top of the support frame 1, a filter separation component 2 provided on the top of the top plate 3, an installation frame 4 fixedly installed on the outer wall of the support frame 1, and sliding grooves 5 opened on the inner walls of both sides of the top of the installation frame 4. A pulley 9 is slidably connected to the inner wall of the sliding groove 5. One end of a connecting rod 7 is fixedly mounted on the outer wall of the pulley 9, and a limit ring 6 is fixedly installed on the other end of the connecting rod 7. A stirring component 8 is provided at the bottom of the sliding groove 5, and a controller 10 is fixedly mounted on the outer wall of the installation frame 4.

[0017] In the above structure, the support frame 1 and the mounting bracket 4 are provided, and the bottoms of the support frame 1 and the mounting bracket 4 are made of natural rubber. Therefore, the bottoms of the support frame 1 and the mounting bracket 4 have an anti-slip function. It can be seen that the support frame 1 and the mounting bracket 4 can support the device while keeping it stable, thereby ensuring the stability of the device in diesel production.

[0018] In a preferred embodiment: there are four connecting rods 7 and four pulleys 9, and the four connecting rods 7 and pulleys 9 are evenly and symmetrically distributed on the outer wall of the limiting ring 6. The diameter of the pulleys 9 is adapted to the width of the groove 5. The bottom of the support frame 1 and the mounting bracket 4 are both made of natural rubber.

[0019] In the above structure, the limiting ring 6 can limit the filter housing 208 and can be engaged with the filter housing 208. At the same time, when the filter housing 208 filters the diesel raw material, the connecting rod 7 will cause the pulley 9 to slide on the inner wall of the slide groove 5, thereby enabling it to counteract the vibration generated by the filter separation component 2 during filtration.

[0020] In a preferred embodiment: the filter separation assembly 2 includes a servo motor 201, the power output shaft of the servo motor 201 is fixedly fitted with a drive wheel 202, the outer wall of the drive wheel 202 is connected to one end of a drive belt 203, and the other end of the drive belt 203 is connected to a driven wheel 204. The top of the driven wheel 204 is fixedly mounted with a mounting post 205, the outer wall of the mounting post 205 is sleeved with one end of a connecting plate 206, and the other end of the connecting plate 206 is mounted on the top of the filter housing 208 by a fixing bolt 207. The bottom of the inner wall of the filter housing 208 is clamped with a filter plate 209.

[0021] In a preferred embodiment: the servo motor 201 is electrically connected to the controller 10, and the servo motor 201 is fixedly installed at the bottom of the top plate 3. The diameter of the driving wheel 202 is smaller than the diameter of the driven wheel 204. The cross-section of the filter shell 208 is trapezoidal, and the outer wall of the filter shell 208 is fitted onto the inner wall of the limiting ring 6.

[0022] In the above structure, the servo motor 201 is started by the signal transmitted by the controller 10, which enables the drive wheel 202 to rotate and drive the driven wheel 204 to rotate synchronously through the transmission belt 203. This allows the mounting column 205 to move the filter shell 208 back and forth on the inner wall of the limiting ring 6 through the connecting plate 206. This allows the filter plate 209 to quickly filter solid impurities such as food residue, plastic, and fiber from the biodiesel feedstock, keeping them on the inner wall of the filter shell 208, while other feedstocks fall onto the inner wall of the mixing drum 801. This effectively removes these solid impurities and ensures the smooth progress of the reaction.

[0023] In a preferred embodiment: the stirring assembly 8 includes a stirring drum 801, a fixing plate 802 is fixedly installed on the inner wall of the stirring drum 801, a dual-shaft drive motor 803 is fixedly installed on the outer wall of the fixing plate 802, a threaded rod 804 is fixedly mounted on the power output shaft of the dual-shaft drive motor 803, one end of a stirring rod 805 is fixedly installed on the outer wall of the threaded rod 804, and a scraper 806 is fixedly mounted on the other end of the stirring rod 805. A filter layer 807 overlaps the top of the stirring drum 801, and the top of the filter layer 807 is respectively provided with mounting holes 808 and filter holes 809.

[0024] In the above structure, the stirring rod 805 can increase the collision frequency of reactant molecules during rotation, accelerate the transesterification reaction, thereby shortening the reaction time and significantly improving the methyl ester conversion rate. At the same time, it can drive the scraper 806 to contact the inner wall of the stirring tank 801, so that the scraper 806 can scrape off the raw materials attached to the inner wall of the stirring tank 801, thereby effectively preventing waste.

[0025] In a preferred embodiment: the dual-axis drive motor 803 is electrically connected to the controller 10, there are two threaded rods 804, and the threads of the two threaded rods 804 are arranged in opposite directions, the stirring rod 805 and the scraper 806 are evenly distributed on the outer wall of the threaded rod 804, and the outer wall of the scraper 806 is in contact with the inner wall of the stirring cylinder 801, and the diameter of the mounting hole 808 is adapted to the threaded rod 804.

[0026] In the above structure, the controller 10 sends a signal to start the dual-shaft drive motor 803, which drives the threaded rods 804 at both ends to rotate in two directions. This, in turn, drives the stirring rod 805 to stir the diesel feedstock on the inner wall of the stirring drum 801, resulting in good stirring effect and helping to distribute heat evenly on the inner wall of the stirring drum 801. This avoids local overheating or overcooling, maintains a stable reaction temperature, thereby improving reaction efficiency and high mixing uniformity, resulting in a higher success rate of biodiesel preparation.

[0027] In summary: When using this device, the raw materials required for biodiesel production can be poured onto the inner wall of the filter housing 208. The controller 10 then sends a signal to start the servo motor 201, causing the drive wheel 202 to rotate. This, in turn, drives the driven wheel 204 to rotate synchronously via the transmission belt 203. This allows the mounting column 205 to reciprocate within the inner wall of the limiting ring 6 via the connecting plate 206. This enables the filter plate 209 to quickly filter solid impurities such as food residue, plastic, and fibers from the biodiesel raw materials, retaining them on the inner wall of the filter housing 208. Other raw materials fall onto the inner wall of the mixing drum 801. After the material has fallen into the container, the controller 10 sends a signal to start the dual-axis drive motor 803, which in turn drives the threaded rods 804 at both ends to rotate in two directions. This, in turn, drives the stirring rod 805 to stir the diesel feedstock on the inner wall of the mixing drum 801, resulting in good stirring effect and helping to distribute heat evenly on the inner wall of the mixing drum 801, avoiding local overheating or undercooling. At the same time, during the stirring process of the stirring rod 805, the scraper 806 can come into contact with the inner wall of the mixing drum 801, so that the scraper 806 can scrape off the feedstock adhering to the inner wall of the mixing drum 801, thereby effectively preventing waste and completing the preparation of biodiesel.
