After the purification of methyl palmitate, the temperature rises and melts after purification, making it difficult to collect quantitatively according to the required amount. After the methyl palmitate is purified and shaped, it needs to be collected manually, which is time-consuming and laborious. Therefore, we propose a new device to solve the above problems.

[0015] In summary, the technical effects and advantages of this utility model are as follows:

[0016] 1. This utility model has a reasonable structure. The stirring structure is rotated by a drive motor, which can crush methyl palmitate. The pressure pump generates downward pressure inside the purification tank, and the heater melts the methyl palmitate. The methyl palmitate is filtered through the upper filter plate, and the melted methyl palmitate flows to the upper surface of the lower filter plate, while the remaining impurities remain on the upper surface of the upper filter plate. The methyl palmitate is filtered again through the lower filter plate. The vibration module driven by the vibration motor can make the lower filter plate vibrate continuously on the upper surface of the spring telescopic rod, so as to avoid impurities clogging the lower filter plate. This solves the problem that too many impurities in methyl palmitate can affect the biodiesel production effect.

The pressure pump 7 generates downward pressure inside the purification chamber 2, and the heater 6 raises the temperature inside the purification chamber 2 to 28 degrees Celsius, which can melt the methyl palmitate. The methyl palmitate can be filtered through the upper filter plate 8, so that the melted methyl palmitate... The ester flows into the upper surface of the lower filter plate 10, while other impurities remain on the upper surface of the upper filter plate 8. Methyl palmitate can be filtered again through the lower filter plate 10.

[0027] like Figure 4 and Figure 5As shown, in this embodiment, a moving motor 14 is fixedly connected inside the equipment base plate 1. A moving screw 15 is inserted into one end of the moving motor 14. A moving slider 16 is threaded through the surface of the moving screw 15. A sliding groove is provided on the upper surface of the equipment base plate 1. The equipment base plate 1 is slidably connected to the moving slider 16 through the sliding groove.

A right mold 19 is inserted into the lower end of the mold motor 18. A collecting hydraulic rod 20 is fixedly connected to the left end of the left mold 17. A push plate 21 is inserted into one end of the collecting hydraulic rod 20. A mold rotating shaft is provided on the front of the right mold 19. The mold rotating shaft is rotatably connected to the left mold 17. Purification box 2 The back of the device is equipped with a lifting seat, inside which a lifting hydraulic rod 22 is fixedly connected. A pressure plate 23 is fixedly connected to the lower end of the lifting hydraulic rod 22, and a cooling plate 24 is fixedly connected to the lower surface of the pressure plate 23. A semiconductor cooler is installed inside the cooling plate 24. A drive slot is formed on the upper surface of the device's base plate 1, and a driver is installed inside the drive slot. The driver is a DM556, a digital two-phase stepper motor driver based on a 32-bit dedicated motor processor. It can be set to microstepping speeds from 400 to 51200 and any current value within the rated current range, meeting the application needs of most situations. The driver integrates an automatic motor parameter recognition function, capable of recognizing different specifications of 57 / 60 motors. The system automatically generates optimal operating parameters to maximize motor performance. The motor operates smoothly with minimal vibration, low noise, and high output. During use, the purified methyl palmitate is evenly discharged according to the required dosage via solenoid valve 13. Methyl palmitate is collected through left mold 17 and right mold 19. A moving motor 14 drives a moving screw 15, causing the moving slider 16 and methyl palmitate to move backward. A lifting hydraulic rod 22 moves the pressure plate 23 downward to flatten the methyl palmitate. Simultaneously, a cooling plate 24 cools the methyl palmitate to set its shape. This system solves the problem of methyl palmitate melting due to temperature rise after purification, which hinders quantitative collection according to the required dosage. The problem of methyl palmitate being quantitatively and uniformly discharged and cooled and shaped by solenoid valve 13 is solved, greatly reducing the operator's workload. The lifting hydraulic rod 22 moves the pressure plate 23 upward to separate it from the methyl palmitate. The mold motor 18 rotates the right mold 19 to the right, and the collecting hydraulic rod 20 moves the push plate 21 to the right, pushing the shaped methyl palmitate into the collection tank. This solves the problem of the time-consuming and laborious manual collection of methyl palmitate after purification and shaping. It achieves the effect of pushing the methyl palmitate into the collection tank by the push plate 21 after shaping, greatly improving the operator's efficiency in collecting methyl palmitate.

[0028] The working principle of this practical application is as follows:

[0029] During use, methyl palmitate is placed inside the purification chamber 2. The cover plate 27 can be rotated by the connecting shaft 25, closing the upper end of the purification chamber 2 by rotating the cover plate 27. The stirring structure 5 is rotated by the drive motor 4, which can break up the methyl palmitate. The pressure pump 7 generates downward pressure inside the purification chamber 2, and the heater 6 raises the temperature inside the purification chamber 2 to 28 degrees Celsius, which melts the methyl palmitate. The methyl palmitate can be filtered through the upper filter plate 8, allowing the melted methyl palmitate to flow into the upper surface of the lower filter plate 10, while other impurities remain on the upper filter plate. The upper surface of filter 8 allows for further filtration of methyl palmitate through the lower filter plate 10. Driven by the vibration motor 12, the vibration module 11 continuously vibrates the upper surface of the spring telescopic rod 9, preventing impurities from clogging the lower filter plate 10. This solves the problem that excessive impurities in methyl palmitate can negatively impact biodiesel production, achieving multiple purification and filtration of impurities within the methyl palmitate, significantly enhancing its purity. The purified methyl palmitate can then be evenly discharged according to the required dosage via the solenoid valve 13. Methyl palmitate can be collected through the left mold 17 and right mold 19. The moving motor 14 drives the moving screw 15, causing the moving slider 16 and methyl palmitate to move backward. The lifting hydraulic rod 22 moves the pressure plate 23 downward to flatten the methyl palmitate. Simultaneously, the cooling plate 24 cools the methyl palmitate to set its shape. This solves the problem that methyl palmitate melts due to increased temperature after purification, making it difficult to collect in precise quantities according to the required amount. It achieves quantitative and uniform discharge of methyl palmitate via the solenoid valve 13 and also cools the methyl palmitate. The shaping effect greatly reduces the operator's workload. The lifting hydraulic rod 22 moves the pressure plate 23 upward to separate it from the methyl palmitate. The mold motor 18 rotates the right mold 19 to the right, and the collecting hydraulic rod 20 moves the push plate 21 to the right, pushing the shaped methyl palmitate into the collection tank. This solves the problem of the time-consuming and laborious manual collection of methyl palmitate after purification and shaping. It achieves the effect of pushing the methyl palmitate into the collection tank by the push plate 21 after shaping, greatly improving the operator's efficiency in collecting methyl palmitate.
