Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of preparation of carboranes, in particular to a continuous flow tubular reactor for preparing carboranes. BACKGROUND

[0002] In the preparation of para-carborane or meta-carborane, the ortho-carborane is directly gasified under inert gas conditions, and the temperature is raised to the corresponding rearrangement temperature to prepare the corresponding product. In the preparation of para-carborane, the ortho-carborane is heated to 615-700 DEG C to obtain para-carborane. Due to the high temperature of the reaction tube, thermal expansion and contraction occur during gradual heating and gradual cooling, and the overall axial deformation is 2-3 cm. If the gasification reaction tube and the feeding mechanism remain in a fixed position, the relative position change between the feeding mechanism and the gasification reaction tube may cause a decrease in the stability of the device, affect the sealing and stability of the mating connection, shorten the overall service life of the equipment, and increase the risk of equipment damage.

[0011] Furthermore, the gasification reaction tube slides through the preheating chamber and the high-temperature reaction chamber, and the side walls of the preheating chamber and the high-temperature reaction chamber are provided with slots that allow the gasification reaction tube to slide through.

Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0025] The number of any elements in the accompanying drawings is for illustrative purposes only and not as a limitation, and any naming is for distinction only and has no limiting meaning.

[0026] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0027] An embodiment of the continuous flow tubular reactor for preparing carboranes provided by this utility model:

[0028] like Figures 1 to 5 As shown,

[0029] The device includes a gasification structure 1 for gasifying carborane feedstock and a feeding mechanism 2 located above the gasification structure 1. The gasification structure 1 includes a gasification reaction pipe 11 that is sealed and connected to the feeding mechanism 2. The gasification structure 1 includes a packing box 12, a preheating box 13, and a high-temperature reaction box 14 arranged in sequence. One end of the gasification reaction pipe 11 is located inside the packing box 12, and the other end passes through the preheating box 13 and the high-temperature reaction box 14 in sequence. The feeding mechanism 2 is located above the packing box 12, and the feed pipe of the feeding mechanism 2 extends into the packing box 12 and is sealed and connected to the gasification reaction pipe 11.

[0030] The feeding mechanism 2 includes a horizontally arranged conveying pipe and a vertically arranged unloading pipe below one end of the conveying pipe. The conveying pipe is equipped with a conveying auger, and one end of the conveying pipe is equipped with a motor that drives the conveying auger to rotate.

[0031] The filler box 12, the preheating box 13 and the high-temperature reaction box 14 are arranged in sequence, and the feeding mechanism 2 is arranged above the filler box 12. In the process of gasification reaction, the temperature difference between the feeding mechanism 2 outside and the corresponding gasification reaction tube 11 is avoided to be large, which affects feeding.

[0032] In the embodiment, the filler box 12 is slidingly arranged on the base 3, and one end of the base 3 is provided with a rack 31. The base 3 is provided with a triangular support frame 33 on one end side for supporting the rack 31. The mounting plate 32 for supporting the feeding mechanism 2 is slidingly arranged on the rack 31. When the gasification reaction tube 11 is axially deformed due to thermal expansion and contraction, the filler box 12 and the feeding mechanism 2 will move left and right synchronously.

[0033] Specifically, in the process of preparing carboranes, o-carborane is heated to 465-500 DEG C to obtain m-carborane through rearrangement reaction; m-carborane is heated to 615-700 DEG C to obtain p-carborane. In the preparation of p-carborane, the gasification reaction tube 11 has a high temperature, and the thermal expansion and contraction in the process of gradually increasing and gradually decreasing will cause an axial deformation of 2-3 cm. When the gasification reaction tube 11 is axially deformed, if the filler box 12 and the feeding mechanism 2 remain in fixed positions, the relative positions of the feeding mechanism 2 and the gasification reaction tube 11 may change, which may cause a decrease in stability of the device.

[0034] By slidingly arranging the filler box 12 and the feeding mechanism 2 and moving left and right when the gasification reaction tube 11 is axially deformed due to thermal expansion and contraction, not only the damage of the gasification reaction tube 11 due to deformation can be effectively coped with, but also the good connection and sealing between the feeding mechanism 2 and the gasification reaction tube 11 can be ensured.

[0035] Specifically, the lower surface of the filler box 12 is provided with a bottom plate 121, the lower surface of the bottom plate 121 is provided with a first sliding block 122, and the upper surface of the base 3 is provided with a first guide sliding rail 30 matched with the first sliding block 122.

[0036] Specifically, the lower surface of the mounting plate 32 is provided with a second sliding block 321, and the upper surface of the rack 31 is provided with a second guide sliding rail 311 matched with the second sliding block 321.

[0037] Further, the lower surface of the mounting plate 32 and the second sliding block 321 are provided with a rubber pad 322.

[0038] Specifically, the first sliding block 122 and the first guide sliding rail 30 and the second sliding block 321 and the second guide sliding rail 311 are electrically matched and driven to move.

[0039] Since the feeding mechanism 2 includes a motor structure, the rubber pad 322 is arranged to improve the stability of the feeding mechanism 2 as a whole.

[0040] In this embodiment, the gasification reaction tube 11 is slidingly penetrated through the preheating box 13 and the high-temperature reaction box 14, and the sidewalls of the preheating box 13 and the high-temperature reaction box 14 are provided with notches 131 allowing the gasification reaction tube 11 to slidingly penetrate through.

[0041] The notches 131 are provided with support rings 132, the inner walls of the support rings 132 are embedded with universal ball bearings 133, and the gasification reaction tube 11 penetrates through the support rings 132 and the outer walls abut against the universal ball bearings 133.

[0042] Since the gasification reaction tube 22 will be axially deformed due to thermal expansion and contraction, the preheating box 13 and the high-temperature reaction box 14 are slidingly supported, and the sliding support can be matched with the left and right movements of the filler box 12 and the feeding mechanism 2.

[0043] The universal ball bearing 133 structure improves the flexibility of the overall structure when the gasification reaction tube 11 deforms, that is, the position of the gasification reaction tube 11 can be easily adjusted when the shaft deforms, and is not hindered too much. The adaptability and reliability of the whole system are improved.

[0044] According to the above description of the present specification, those skilled in the art can also understand that the terms used such as "upper", "lower", "front", "rear", "left", "right", "width", "horizontal", "top", "bottom", "inner", "outer" and the like indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the drawings of the present specification, and are only for the purpose of facilitating the description of the scheme of the present application and simplifying the description, and do not explicitly or implicitly indicate or imply that the devices or elements involved must have the described specific orientation, be constructed and operated in a specific orientation, therefore the above orientation or positional relationship terms cannot be understood or interpreted as a limitation on the scheme of the present application.

[0045] In addition, in the description of the present specification, the meaning of "a plurality of" is at least two, such as two, three or more, etc., unless otherwise explicitly and specifically limited.
