Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] Embodiment 1:

[0025] Reference Figure 1 to Figure 2As shown, this embodiment provides an ester condensation reaction product separation device, including a bottom plate 14, the top surface of the bottom plate 14 is slidably connected to an extraction shell 1, the top surface of the extraction shell 1 is provided with a feeding port, the feeding port is rotatably connected to a cover body 2, the bottom wall of the extraction shell 1 is provided with a distance sensor 16, the top surface of the extraction shell 1 is fixedly connected to a first telescopic rod 3, the first telescopic rod 3 is vertically arranged, the bottom end of the first telescopic rod 3 is fixedly connected to a liquid collection head 4, the liquid collection head 4 is connected to a distillation component, a condensate discharge pipe 18 is provided on the distillation component, the distillation outlet of the distillation component is connected to the upper part of the side wall of the extraction shell 1, the lower part of the side wall of the extraction shell 1 is connected to the inlet and outlet of the circulation component, the middle part of the circulation component is heat exchanged with the distillation component, the side wall of the extraction shell 1 is connected to a vibration component, and the vibration component is fixedly connected to the bottom plate 14.

[0026] The height of the interface is detected by the distance sensor 16, and then the telescopic length of the first telescopic rod 3 is controlled to drive the liquid taking head 4 to take out the lower layer of liquid and send it into the distillation component. A circulation component is arranged at the lower part of the side wall of the extraction shell 1, and the liquid of the lower layer of liquid can be used to cool the condensation process of the distillation component. The heat released during the condensation process of the distillation component is sent back to the inside of the extraction shell 1 by the circulation component, which accelerates the reaction of the extraction process. The liquid condensed by the heat exchange after distillation of the distillation component is discharged through the condensate discharge pipe 18. At this time, the liquid retained in the distillation component is alkane, which is sent into the extraction shell 1 again to further accelerate the extraction reaction.

[0027] Further optimized solution, the vibration assembly includes a connection block 102 fixedly connected to the side wall of the extraction shell 1, the connection block 102 is rotatably connected to one end of the second telescopic rod 1403, the other end of the second telescopic rod 1403 is slidably limited with a wheel 1402, the wheel 1402 is connected to the output shaft of the motor 1401, and the motor 1401 is fixedly connected to the top surface of the bottom plate 14;

[0028] A sliding installation groove 1404 is provided on the wheel disc 1402 , and the sliding installation groove 1404 runs through the upper and lower surfaces of the wheel disc 1402 . The other end of the second telescopic rod 1403 is slidably limitedly matched with the sliding installation groove 1404 through a bolt.

[0029] By controlling the motor 1401 to rotate, the motor 1401 drives the wheel 1402 to rotate, and the wheel 1402 drives the second telescopic rod 1403 to move and then drives the extraction shell 1 to oscillate, the reaction rate of the extraction process can be accelerated, and the position of the bolt fixed in the sliding mounting groove 1404 can be adjusted. After the adjustment, the second telescopic rod 1403 adjusts its telescopic length accordingly. By cooperating, the oscillation amplitude of the extraction shell 1 can be adjusted, thereby adapting to different types of reaction processes.

[0030] A further optimized solution is provided, in which the distillation component includes a distillation box 9, a side wall of which is connected to one end of an upper liquid pipeline 6, the other end of the upper liquid pipeline 6 is connected to the side wall of the extraction shell 1, the upper liquid pipeline 6 is connected to the liquid taking head 4 through a hose 5, a first pump body 8 is connected to the upper liquid pipeline 6, a heating component 15 is installed on the bottom surface of the distillation box 9, an evaporation pipeline 10 is connected to the top surface of the distillation box 9, a condensate discharge pipe 18 is connected to the evaporation pipeline 10, a third pump body 17 is provided in the middle of the evaporation pipeline 10, a spiral section of the evaporation pipe 11 is provided in the middle of the evaporation pipeline 10, and the middle part of the circulation component is heat exchanged with the spiral section of the evaporation pipe 11.

[0031] A further optimized solution is that the circulation component includes a lower liquid circulation pipeline 12 whose two ends are connected to the lower part of the side wall of the extraction shell 1, the lower liquid circulation pipeline 12 is wound around the spiral section 11 of the evaporation tube, the lower liquid circulation pipeline 12 exchanges heat with the spiral section 11 of the evaporation tube, and a second pump body 13 is provided on the lower liquid circulation pipeline 12.

[0032] The lower layer liquid is circulated through the second pump body 13 , and the lower layer liquid circulation pipeline 12 takes away the heat of the spiral section 11 of the evaporation tube to achieve condensation, and can send the released heat back to the extraction shell 1 .

[0033] To further optimize the solution, the two ends of the lower liquid circulation pipeline 12 are respectively a liquid inlet end and a liquid outlet end, the liquid inlet end is connected to the liquid inlet of the second pump body 13, the liquid outlet end is connected to the liquid outlet of the second pump body 13, and the height of the liquid inlet end is higher than the height of the liquid outlet end.

[0034] The height of the liquid inlet end is higher than that of the liquid outlet end. This arrangement enables the liquid with high heat returning to achieve heat convection at the position of the lower layer of liquid, thereby increasing the reaction rate.

[0035] In a further optimized solution, a liquid level sensor 7 is installed on the side wall of the extraction housing 1. The liquid level sensor is used to measure the liquid level in the extraction housing 1.

[0036] In a further optimized solution, an observation window 101 is provided on the side wall of the extraction housing 1. The observation window 101 can be provided to facilitate observation of the reaction process.

[0037] Embodiment three:

[0038] Reference Figure 3As shown, the difference between this embodiment and the first embodiment is that a cooling fan 19 is provided between the second pump body 13 and the outlet end of the lower liquid circulation pipeline 12 to cool the liquid in the lower liquid circulation pipeline 12 that exchanges heat with the evaporator tube spiral section 11, which can further accelerate the condensation process of the evaporator tube spiral section 11. Since the heat in the evaporator tube spiral section 11 is relatively high, although some heat will be lost after heat exchange, it still has a certain amount of heat when it is sent into the extraction shell 1. Although it will reduce a certain reaction rate, some heat in the lower liquid circulation pipeline 12 will also be sent back to the extraction shell 1, which will not affect the overall reaction rate of the device.

[0039] In the utility model, the first telescopic rod 3 and the second telescopic rod 1403 can be electric telescopic rods, and the liquid level height sensor 7, the first pump body 8, the second pump body 13, the motor 1401, the first telescopic rod 3, the second telescopic rod 1403, the heating component 15, the distance sensor 16, the third pump body 17, the cooling fan 19 and other components can be connected to a controller with a control function, such as a PLC controller, to achieve control of the entire reaction process. The specific connection method and control method are existing technologies and will not be repeated here.

Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
