Description
Technical Field
[0001] This utility model relates to the field of chemical production technology, specifically a biodiesel dewaxing device. Background Technology
[0002] Biodiesel, as a renewable and clean energy source, has advantages such as being environmentally friendly and renewable, and its application in transportation, industrial fuel and other fields is becoming increasingly widespread.
[0003] In the prior art, CN220835064U discloses a biodiesel pour point depressing device, including a base with supporting legs at the four corners of the base's bottom, a pour point depressing tank at the top of the base, an oil delivery pipe at the top of the pour point depressing tank, an oil outlet pipe at the bottom of the pour point depressing tank, and two connecting grooves at the top of the pour point depressing tank. A filter box is provided on the surface of the oil delivery pipe, and a cover plate is provided on one side of the filter box. The cover plate is connected to the filter box by screws. The filter box has four sliding grooves at both the top and bottom, with each of the four sliding grooves corresponding to the other two. A first filter screen is provided in each sliding groove, and a second filter screen is provided on one side of the first filter screen, etc.
[0004] While the first and second filters described above can filter impurities in biodiesel, impurities inevitably accumulate on the filter surface. This necessitates disassembling and cleaning the filters, and simultaneously stopping the dewaxing process of biodiesel, reducing the dewaxing efficiency and making the process inconvenient. Therefore, further optimization is needed to address these issues. Utility Model Content
[0005] To address the shortcomings of existing technologies, this invention provides a biodiesel dewaxing device, which solves the problems mentioned in the background section.
[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a biodiesel dewaxing device, comprising a mixing tank, a fixed shell, a stirring component, a filter disc, and a top cover. The top cover is located on the top of the mixing tank, the fixed shell is located on the top of the top cover, the filter disc is detachably connected to the inside of the fixed shell for filtering biodiesel, and the stirring component is located inside the mixing tank.
[0007] A driving component is provided on a platform on one side of the fixed shell. An adjusting component is provided at the output end of the driving component. One end of the adjusting component extends into the interior of the fixed shell and is engaged in the groove at the center of the filter disc. A power rod is engaged with the surface of the output end of the driving component. The bottom end of the power rod is used in conjunction with the top end of the stirring component. A feed pipe one and a feed pipe two are provided on the other side of the fixed shell.
[0008] This utility model has the following beneficial effects:
[0009] This biodiesel pour point depressant device features a removable filter disc, which is easier to disassemble and clean quickly compared to the fixed filter screens in existing technologies. The drive component rotates the adjustment component, one end of which is engaged in a groove at the center of the filter disc, thus driving the filter disc to rotate. This not only filters the biodiesel and pour point depressant but also allows for cleaning without disassembling the filter disc, greatly reducing downtime caused by cleaning the filter screen. This improves the overall efficiency of biodiesel pour point depressant and avoids the impact of frequent downtime on production progress.
[0010] This biodiesel pour point depressant device utilizes a helical gear on the surface of a rotating rod to mesh with a power rod. The bottom end of the power rod works in conjunction with a stirring element, enabling the stirring element to operate synchronously. This design achieves synergy between filtration and stirring functions. The stirring element allows the biodiesel to be fully mixed in the mixing tank, which is beneficial for the uniform contact between the pour point depressant and the biodiesel, thus improving the pour point depressant reaction effect. When the filter disc rotates, the cleaning rod helps to prevent impurities from accumulating locally on the surface of the filter disc, further reducing the possibility of clogging.
[0011] This biodiesel dewaxing device has a detachable impurity box inserted into the side of the fixed shell near the feed pipe, which can collect impurities generated during the filtration process in a timely manner. In addition, the positioning rod rotatably connected to the side of the fixed shell can limit the impurity box, which facilitates the installation and removal of the impurity box, makes it easier to centrally process impurities, keep the inside of the device clean, and reduce the impact of impurities on the dewaxing process. Pulling the adjusting rod to the right can move the docking cylinder out of the groove in the center of the filter disc, which facilitates the removal of the filter disc. Attached Figure Description

[0019] 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.
[0020] Please see Figures 1 to 6 This utility model provides a biodiesel dewaxing device, including a mixing tank 1, a fixed shell 2, a stirring component 3, a filter disc 4, and a top cover 5. The top cover 5 is located on the top of the mixing tank 1, the fixed shell 2 is located on the top of the top cover 5, the filter disc 4 is detachably connected to the inside of the fixed shell 2 for filtering biodiesel, and the stirring component 3 is located inside the mixing tank 1.
[0021] As attached Figure 1 As shown, the fixed housing 2 also includes a cover plate (shown in the figure, not labeled) on the top. A groove adapted to the size of the cover plate is provided on the top of the fixed housing 2, so that the cover plate can be fastened into the inside of the groove. Limiting rods 17 are inserted into both ends of the top of the fixed housing 2. A return spring 18 is sleeved on the surface of one end of the limiting rod 17 that extends into the inside of the fixed housing 2. The limiting rod 17 can limit the cover plate by the force of the return spring 18, reducing loosening during equipment operation.
[0022] A handle is provided on the top of the cover plate for hand-holding, which can be used to remove the filter disc 4 inside the fixed shell 2 when it needs to be disassembled.
[0023] The bottom of the mixing tank 1 is fixedly connected with support legs 10, which can support the equipment and maintain the stability of the equipment. The bottom of the mixing tank 1 is fixedly connected with the discharge pipe 11. The surface of the discharge pipe 11 is provided with a valve 12. Opening the valve 12 allows the mixed biodiesel to be discharged from the discharge pipe 11. The side of the top cover 5 is fixedly connected with a fixing ring 13. One end of the fixing ring 13 passes through the inner side wall of the top cover 5 and abuts against the outer wall of the mixing tank 1.
[0024] Rotating the fixing ring 13 allows one end to abut against the outer wall of the mixing tank 1, making it easy to install the top cover 5 on the top of the mixing tank 1 and also easy to disassemble for cleaning the internal stirring component 3.
[0025] The mixing component 3 includes a rotating shaft inside the mixing tank 1 and a spiral conveyor plate on the surface of the rotating shaft. When the rotating shaft rotates, the spiral conveyor plate rotates in the forward direction, which allows the biodiesel and pour point depressant to continuously surge upward, improving the mixing efficiency. When the spiral conveyor plate rotates in the reverse direction, the mixed biodiesel can be quickly discharged from the discharge pipe 11, thereby increasing the discharge speed.
[0026] A groove is provided at the top of the rotating shaft to match the bottom of the power rod 7. In this way, the power rod 7 can be quickly inserted into the inside of the stirring component 3 and drive it to rotate synchronously. A scraper is provided on the outer wall of the top of the rotating shaft. The scraper is located in the part that fits the inner wall of the mixing tank 1. When the rotating shaft rotates, it can drive the scraper to rotate at the same time, which makes it easy to keep the inner wall of the mixing tank 1 clean.
[0027] The fixed shell 2 is connected to the mixing tank 1 through the top cover 5. The inner side wall of the fixed shell 2, near the top cover 5, is provided with a baffle 22. The top of the fixed shell 2 is provided with a detachable cleaning rod 16, which works in conjunction with the filter disc 4. A detachable impurity box 14 is inserted into the side of the fixed shell 2 near the feed pipe 8, which facilitates the collection of impurities filtered on the surface of the filter disc 4 for centralized treatment. A positioning rod 15 is rotatably connected to the side of the fixed shell 2 to limit the position of the impurity box 14. When disassembling, the impurity box 14 can be disassembled by holding the positioning rod 15 and turning it to the left or right. A sealing gasket is provided at the contact point between the impurity box 14 and the fixed shell 2 to increase the sealing at the connection and prevent biodiesel and pour point depressant from seeping out.
[0028] like Figure 3 As shown, with the cooperation of the baffle 22, the biodiesel and pour point depressant entering the fixed shell 2 can be initially mixed, so as to reduce the mixing time of the subsequent stirring component 3 and improve the efficiency of use.
[0029] In order to reduce the accumulation of impurities on the surface of the filter disc 4, a cleaning layer (bristles) is provided on the surface of the cleaning rod 16 that extends into the inside of the fixed shell 2, and the cleaning layer is attached to the side of the filter disc 4. When the filter disc 4 rotates, with the help of the cleaning layer, the impurities on its surface can be cleaned, reducing the accumulation of impurities.
[0030] A drive unit is provided on the platform on one side of the fixed shell 2. An adjustment unit 6 is provided at the output end of the drive unit. One end of the adjustment unit 6 extends into the interior of the fixed shell 2 and is engaged in the groove at the center of the filter plate 4. A power rod 7 is engaged with the surface of the output end of the drive unit. The bottom end of the power rod 7 is used in conjunction with the top end of the stirring unit 3. A feed pipe 1 8 and a feed pipe 2 9 are provided on the other side of the fixed shell 2.
[0031] The driving component includes a protective shell 19 on the top of the fixed shell 2, a motor 20 inside the protective shell 19, and a rotating rod 21 at the output end of the motor 20. The other end of the rotating rod 21 extends into the interior of the adjusting component 6. The surface of the rotating rod 21 is provided with a helical gear and is meshed with the power rod 7. One end of the protective shell 19 is fixedly connected to one side of the fixed shell 2.
[0032] An auxiliary rod is fixedly connected to the side of the fixed shell 2 near the protective shell 19, and the bottom end of the auxiliary rod is fixedly connected to the platform on the right side of the fixed shell 2. This can increase the stability of the fixed shell 2 in use.
[0033] like Figure 3-5 As shown, starting the motor 20 can drive the rotating rod 21 to rotate. Since the other end of the rotating rod 21 extends into the interior of the adjusting component 6, and the other end of the adjusting component 6 extends into the groove at the center of the filter disc 4, the filter disc 4 is driven to rotate. The feed pipe 1 8 and feed pipe 2 9 can be connected to the external biodiesel and pour point depressant equipment, respectively. At this time, after being filtered by the filter disc 4, the biodiesel and pour point depressant pass through the baffle plate 22 and enter the interior of the mixing tank 1 through the top cover 5. Since the top of the power rod 7 is engaged with the adjusting component 6, it synchronously drives the stirring component 3 to rotate, which facilitates the mixing of biodiesel and pour point depressant.
[0034] The adjusting component 6 includes a docking cylinder 601 sleeved on the surface of the rotating rod 21, a compression spring 602 fixedly connected to the rotating rod 21 inside the docking cylinder 601, and an adjusting rod 603 sleeved on the outer wall of the docking cylinder 601.
[0035] A sealing gasket is fitted on the outer wall of one end of the docking cylinder 601 that extends into the fixed shell 2. The sealing gasket is fixedly connected to the inner wall of the fixed shell 2, which can increase the sealing between the docking cylinder 601 and the fixed shell 2.
[0036] To facilitate the disassembly of the filter disc 4, move the hand adjustment rod 603 to the right, which will allow the docking cylinder 601 to move out of the groove of the filter disc 4. At this time, open the cover plate to remove the filter disc 4 for replacement and maintenance. When installing the filter disc 4, under the force of the docking cylinder 601 and the compression spring 602, it will quickly extend to the groove to complete the installation.
[0037] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.
[0038] In this invention, the working steps of the device are as follows:
[0039] In use, feed pipe 8 and feed pipe 9 are connected to the external biodiesel and pour point depressant storage equipment. Start motor 20, and with the cooperation of rotating rod 21, adjusting component 6 and power rod 7, synchronously drive filter disc 4 and stirring component 3 to rotate. Biodiesel and pour point depressant can be filtered through filter disc 4, and then mixed evenly through stirring component 3. The mixed biodiesel can be discharged through discharge pipe 11.
[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
