[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0023] Embodiment 1
[0024] Please refer to Figures 1-5, this embodiment provides a catalytic distillation column for methyl tert-butyl ether, which includes a distillation cylinder 1 and a distillation mechanism 2. At the edge position of the bottom end face of the distillation cylinder 1, support legs are vertically and fixedly arranged. The distillation cylinder 1 is lifted off the ground by the support legs to facilitate the use of the distillation cylinder 1.
[0025] The distillation cylinder 1 has a hollow structure, and the hollow structure of the distillation cylinder 1 serves as a place for installing the components required for distillation.
[0026] The top end of the distillation cylinder 1 is provided with a feed inlet, and a feed hopper 11 is arranged at the opening of the feed inlet. The distillation mechanism 2 is arranged inside the distillation cylinder 1. Through the feed hopper 11, the methyl tert-butyl ether to be distilled can be filled into the hollow structure, so that the distillation mechanism 2 can perform distillation operations on the filled methyl tert-butyl ether.
[0027] The distillation mechanism 2 includes a liquid storage cylinder 23, which is fixedly arranged at the inner top end of the distillation cylinder 1. The top end of the liquid storage cylinder 23 is provided with a liquid inlet that is seamlessly connected to the feed inlet. The methyl tert-butyl ether filled from the feed hopper 11 directly flows into the liquid storage cylinder 23 through the liquid inlet and waits for distillation operations.
[0028] Several annular sleeves 211 that are evenly spaced in a ring shape are formed by the bottom end face of the liquid storage cylinder 23 bulging towards the inside of the liquid storage cylinder 23. The internal space of the liquid storage cylinder 23 is divided into several liquid storage cavities by the several annular sleeves 211, so that the methyl tert-butyl ether filled into the liquid storage cylinder 23 is distributed in each liquid storage cavity. An annular heating plate 28 is arranged inside each annular sleeve 211. By heating with the annular heating plate 28, the methyl tert-butyl ether in each liquid storage cavity can be distilled.
[0029] In this way, the traditional method of directly distilling using a single liquid storage cylinder 23 is changed. By adopting a segmented distillation method, the methyl tert-butyl ether in the liquid storage cylinder 23 can be evenly divided, and then heated and distilled simultaneously by several annular heating plates 28, which can greatly improve the distillation efficiency, shorten the distillation time, and is simple and practical.
[0030] An inverted J-shaped condensing pipe 24 is connected to the upper end face of the liquid storage cylinder 23. Through the inverted J-shaped condensing pipe 24, the effective components extracted by distillation can be condensed.
[0031] An annular hollow drainage tray 13 is fixedly arranged at the bottom end of the inner side wall of the distillation cylinder 1. An annular drainage groove is opened on the upper end face of the annular hollow drainage tray 13. The effective components obtained by distillation extraction drip along the inner wall of the inverted J-shaped condensing pipe 24 and are centrally collected inside the annular drainage groove.
[0032] Embodiment 2
[0033] Please refer to Figures 1-5 , and further improvements are made on the basis of Embodiment 1:
[0034] When the annular drainage groove is full, drainage holes 25 communicating with the inside of the annular drainage groove are formed in the outer wall of the annular hollow drainage tray 13. The collected distilled active ingredients flow out from the drainage holes 25. A drainage pipe 12 is connected to the bottom end of the outer wall of the distillation cylinder 1, and the drainage pipe 12 penetrates through the distillation cylinder 1 and is seamlessly docked with the drainage holes 25, and then directly enters the drainage pipe 12. The staff can use a collection cylinder to receive at the opening of the drainage pipe 12.
[0035] The distillation mechanism 2 further includes a driving motor 21. The driving motor 21 is fixedly arranged on the bottom end surface of the distillation cylinder 1. A chassis 27 is fixedly arranged between the bottom end surfaces of a plurality of annular heating plates 28. The power shaft of the driving motor 21 rotates and extends into the distillation cylinder 1 and is fixedly connected with a transmission rod 22 capable of supporting the chassis 27. The annular heating plates 28 are rotatably arranged inside the annular sleeve 211. The driving motor 21 provides power to drive the transmission rod 22 to rotate. The rotating transmission rod 22 can drive the chassis 27 to rotate, so that a plurality of annular heating plates 28 rotate inside the annular sleeve 211 at corresponding positions, which can accelerate the heat flow rate and improve the distillation efficiency.
[0036] In order to play a preheating role, a buffer groove with a rectangular cross-section in a top view is formed at the top end of the transmission rod 22. A rectangular slider 29 is slidably inserted inside the buffer groove. The top end of the rectangular slider 29 is fixedly connected with a rectangular connecting rod 26 extending above the notch of the buffer groove. The top end of the rectangular connecting rod 26 is fixedly connected with the bottom end surface of the chassis 27. The rotation of the transmission rod 22 can drive the rectangular slider 29 to rotate synchronously, so as to drive the rectangular connecting rod 26 to rotate, so that the chassis 27 rotates. At the same time, the rectangular slider 29 can slide up and down inside the buffer groove with a rectangular structure, so as to drive a plurality of annular heating plates 28 at the upper end of the chassis 27 to adjust their positions up and down, so that the annular heating plates 28 approach and separate from the inside of the annular heating plates 28. By adjusting the height of the annular heating plates 28 up and down, it is possible to prevent the annular heating plates 28 from continuously heating the annular sleeve 211, playing a preheating role.
[0037] A first electromagnet 210 is fixedly embedded in the bottom end surface inside the buffer groove. A second electromagnet is fixedly embedded in the bottom end surface of the rectangular slider 29 and is vertically opposite to the first electromagnet 210. By intermittently supplying power to the first electromagnet 210 and the second electromagnet, the first electromagnet 210 and the second electromagnet can generate mutually repulsive magnetic forces after being energized, which can slide the rectangular slider 29 upward, so as to automatically control the up and down adjustment of the position of the annular heating plates 28.
