Abstract
Description
Technical Field
[0001] This application belongs to the field of biodiesel technology, specifically a biodiesel production equipment. Background Technology
[0002] Biodiesel refers to fatty acid methyl esters or ethyl esters formed by esterification of vegetable oils (such as rapeseed oil, soybean oil, peanut oil, corn oil, cottonseed oil, etc.), animal oils (such as fish oil, lard, tallow, mutton tallow, etc.), waste oils, or microbial oils with methanol or ethanol. Biodiesel is a typical "green energy" source, characterized by good environmental performance, good engine starting performance, good fuel performance, and a wide range of renewable raw material sources. Vigorously developing biodiesel is of significant strategic importance for sustainable economic development, promoting energy substitution, reducing environmental pressure, and controlling urban air pollution.
[0003] For example, patent CN221192080U discloses an easy-to-clean biodiesel production device. This easy-to-clean biodiesel production device includes a base, with uprights fixedly installed on the left and right sides and the front and rear sides of the upper surface of the base. A rectangular bracket is fixedly installed at the top of each upright, and a cleaning component is fixedly installed on the upright. The rectangular bracket is equipped with a washing assembly. This easy-to-clean biodiesel production device utilizes a rotating motor and flexible enclosure in the cleaning assembly, thus employing a working surface and a replacement surface. When the working surface needs cleaning, it is rotated, and the replacement surface serves as the inner wall of the processing chamber. This allows for external cleaning of the original inner wall, improving work efficiency without affecting processing and providing better surface cleaning.
[0004] However, the biodiesel production equipment proposed in this application lacks a structure in front of the equipment that can automatically press and filter biological raw materials, which may result in excessive impurities before the biodiesel reaction. Utility Model Content

[0007] By adopting the above technical solution, the pressing tank is used to press the biological raw materials, the filter tank is used to filter the pressed liquid, the catalytic reaction tank is used to add reaction catalysts to prepare diesel and glycerin from the filtered liquid, and the settling tank is used to separate diesel and glycerin by sedimentation. A sliding filter screen is installed at the upper part of the filter tank, which filters the pressed biological raw materials, trapping the tissue on the screen surface and retaining the oil inside the filter tank. In use, the biological raw materials are first fed into the pressing tank, where they are pressed by the screw pressing shaft. The pressed tissue and oil are discharged from the oil outlet pipe and fall onto the filter screen inside the filter tank. Activating the hydraulic rod in the support frame moves the lifting rod at the top of the hydraulic rod up and down, which in turn moves the support ring and side extension rod. The side extension rod pulls the filter screen from inside the filter tank to the surface, facilitating cleaning and recovery of the tissue.
[0008] In a preferred embodiment, a fixing frame is fixedly connected to the top side of the bracket, a mounting base is fixedly installed at the top of the fixing frame, and a pressing barrel is fixedly installed on the inner side of the mounting base.
[0009] By adopting the above technical solution, the top of the pressing barrel is fixed by the mounting base and the fixing frame, which makes it convenient to install the pressing barrel on the top of the bracket and the upper end of the filter barrel.
[0010] In a preferred embodiment, a spiral pressing shaft is rotatably connected inside the pressing barrel, and a first motor is installed at the left end of the spiral pressing shaft.
[0011] By adopting the above technical solution, when it is necessary to press oil, the first motor can be started, and the first motor drives the motor output shaft to rotate, which in turn drives the spiral pressing shaft inside the pressing barrel to rotate.
[0012] In a preferred embodiment, a feeding hopper is fixedly installed on the right end surface of the pressing barrel and at the upper end of the spiral pressing shaft.
[0013] By adopting the above technical solution, when the raw material enters from the inside of the feeding hopper, it can be pressed by the rotating screw pressing shaft and moved to the left end, and finally discharged through the oil outlet pipe.
[0014] In a preferred embodiment, a feed pipe is fixedly connected to the top of the catalytic reaction tank, and a valve is installed on the surface of the discharge pipe.

[0018] In a preferred embodiment, a plurality of stirring blades are mounted on the side end of the stirring shaft.
[0019] By adopting the above technical solution, the rotation of multiple stirring blades inside the catalytic reaction tank can fully stir the added oil and catalyst, thereby increasing the reaction rate.
[0020] In a preferred embodiment, a plurality of support legs are fixedly connected to the side end of the catalytic reaction tank.
[0021] By adopting the above technical solution, the support legs are used to support the bottom of the catalytic reaction tank of the device, thereby improving the overall stability of the device.
[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:
[0023] In this application, during use, the biomaterials are first fed into the pressing tank, where they are pressed by a screw pressing shaft. When the raw material enters from the hopper, it is pressed by the rotating screw pressing shaft and moves to the left, eventually exiting through the oil outlet pipe. The pressed material and oil are discharged from the oil outlet pipe and fall onto the filter screen inside the filter tank. The filtered oil is then sent to the catalytic reaction tank via a drain pipe for catalytic reaction. Inside the catalytic reaction tank, a catalyst is added to induce transesterification, producing biodiesel and glycerol. During the transesterification reaction, a second motor can be started simultaneously to rotate the stirring shaft inside the catalytic reaction tank. The rotation of the stirring shaft drives multiple stirring blades inside the catalytic reaction tank, thoroughly agitating the added oil and catalyst, thus increasing the reaction rate. The catalyst, being a volatile substance, is discharged through the feed pipe. It is then sent to the settling tank for separation through the discharge pipe. When it is necessary to clean the filter screen, the hydraulic rod inside the bracket can be activated first, which will move the lifting rod at the top of the hydraulic rod up and down, thereby moving the support ring and the side extension rod. The side extension rod is used to pull the filter screen from the inside of the filter barrel to the surface of the filter barrel, making it convenient for staff to clean and recover the filter screen.

[0030] Example:
[0031] Reference Figure 1-4 The system includes a filter barrel 1, with a filter screen 18 slidably connected inside.

A discharge pipe 15 is fixedly connected to the lower end of the catalytic reaction barrel 3, and a settling tank 4 is fixedly installed at the other end of the discharge pipe 15 away from the catalytic reaction barrel 3. The pressing barrel 9 is used to press biological raw materials, the interior of the filter barrel 1 is used to filter the pressed liquid, the interior of the catalytic reaction barrel 3 is used to add reaction catalysts to prepare diesel and glycerin from the filtered liquid, and the interior of the settling tank 4 is used to separate the diesel and glycerin through sedimentation. A sliding filter screen 18 is installed at the upper part of the inside of the filter tank 1. The pressed biomaterial is filtered through the filter screen 18, with the tissues remaining on the surface of the screen and the oil retained inside the filter tank 1. In use, the biomaterial is first fed into the pressing tank 9, where it is pressed by the screw pressing shaft 16. The pressed tissues and oil are discharged from the oil outlet pipe 17 and fall onto the filter screen 18 inside the filter tank 1. The oil, after passing through the filter screen 18, is sent through the drain pipe 11 to the catalytic reaction tank 3 for catalytic reaction. Inside the catalytic reaction tank 3, a catalyst can be added to cause the oil to undergo transesterification, producing biodiesel and glycerol. Then, it is sent through the discharge pipe 15 to the settling tank 4 for separation. When it is necessary to clean the filter material at the filter screen 18, the hydraulic rod 5 inside the bracket 2 can be activated first, which will drive the lifting rod 21 at the top of the hydraulic rod 5 to move up and down, thereby driving the support ring 20 and the side extension rod 19 to move. The side extension rod 19 is used to pull the filter screen 18 from the inside of the filter barrel 1 to the surface of the filter barrel 1, making it convenient for staff to clean and recover the filter material.

A pressing barrel 9 is fixedly installed on the inner side of the mounting base 8. The top of the pressing barrel 9 is fixed by the mounting base 8 and the fixing frame 7, which facilitates the installation of the pressing barrel 9 on the top of the bracket 2 and the upper end of the filter barrel 1.
[0033] Reference Figure 1 and Figure 2 The pressing barrel 9 is internally connected to a spiral pressing shaft 16, and a first motor 6 is installed at the left end of the spiral pressing shaft 16. When it is necessary to press the oil, the first motor 6 can be started, which drives the motor output shaft to rotate, thereby driving the spiral pressing shaft 16 inside the pressing barrel 9 to rotate, and using the spiral pressing shaft 16 to press the biological raw materials.
[0034] Reference Figure 1 and Figure 2 A feeding hopper 10 is fixedly installed on the right end surface of the pressing barrel 9 and above the screw pressing shaft 16. The feeding hopper 10 is located on the upper right side of the pressing barrel 9, and the oil outlet pipe 17 is located on the lower left side of the pressing barrel 9. When the raw material enters from the inside of the feeding hopper 10, it can be pressed by the rotating screw pressing shaft 16 and moved to the left end, and finally discharged through the oil outlet pipe 17.
[0035] Reference Figure 1 and Figure 4 The top of the catalytic reaction tank 3 is fixedly connected to a feed pipe 22, and a valve 14 is installed on the surface of the discharge pipe 15. The feed pipe 22 at the top of the catalytic reaction tank 3 allows workers to easily add the catalyst required for the transesterification reaction. When the reaction inside the catalytic reaction tank 3 is complete and the oil is reacting to produce biodiesel and glycerin, the valve 14 can be opened to allow the mixed oil inside the catalytic reaction tank 3 to flow through the discharge pipe 15 into the settling tank 4.
[0036] Reference Figure 1 and Figure 4 A second motor 12 is fixedly installed at the top of the catalytic reaction tank 3, and a stirring shaft 23 is fixedly connected to the lower end of the second motor 12 and located inside the catalytic reaction tank 3.

[0037] Reference Figure 1 and Figure 4 Multiple stirring blades 24 are installed on the side of the stirring shaft 23. When the stirring shaft 23 rotates, it drives the multiple stirring blades 24 inside the catalytic reaction tank 3 to rotate, which can fully stir the added oil and catalyst, and improve the reaction rate. The catalyst is a volatile substance and can be discharged through the feed pipe 22.
[0038] Reference Figure 1Multiple support legs 13 are fixedly connected to the side of the catalytic reaction tank 3. The support legs 13 are used to support the bottom of the catalytic reaction tank 3 and improve the overall stability of the device.
[0039] The implementation principle of a biodiesel production equipment embodiment of this application is as follows: In use, the biomass is first fed into the pressing tank 9, where it is pressed by the screw pressing shaft 16. A first motor 6 is started, driving the output shaft to rotate, which in turn rotates the screw pressing shaft 16 within the pressing tank 9, thus pressing the biomass. The feeding hopper 10 is located on the upper right side of the pressing tank 9, and the oil outlet pipe 17 is located on the lower left side of the pressing tank 9. When the raw material enters from the feeding hopper 10, it is pressed by the rotating screw pressing shaft 16 and moves to the left, finally being discharged through the oil outlet pipe 17. The pressed material and oil are discharged from the oil outlet pipe 17 and fall into the filter screen 18 inside the filter tank 1. The oil, after passing through the filter screen 18, can be sent to the catalytic reaction tank 3 through the drain pipe 11 for catalytic reaction. Inside the catalytic reaction tank 3, a catalyst can be added to allow the oil to undergo an ester exchange reaction, producing biodiesel and glycerol. During the transesterification reaction, the second motor 12 can be started simultaneously to rotate the stirring shaft 23 inside the catalytic reaction tank 3. The rotation of the stirring shaft 23 drives multiple stirring blades 24 inside the catalytic reaction tank 3 to rotate, thoroughly stirring the added oil and catalyst to increase the reaction rate. The catalyst is a volatile substance and can be discharged through the feed pipe 22. It is then sent to the settling tank 4 for separation through the discharge pipe 15. When it is necessary to clean the filter screen 18, the hydraulic rod 5 inside the support 2 can be activated first, causing the lifting rod 21 at the top of the hydraulic rod 5 to move up and down, thereby moving the support ring 20 and the side extension rod 19. The side extension rod 19 pulls the filter screen 18 from inside the filter tank 1 to the surface of the filter tank 1, facilitating cleaning and recovery of the material. This device can automatically press and extract oil from biological raw materials before the reaction, and filter the oil. The filtered material is easy to recover, reducing impurities in the raw materials and improving product quality.
