Description

Technical Field

[0001] The utility model relates to the technical field of fixing devices, in particular to a fixing device for the distillation of ethylene carbonate hydrolysis ethylene glycol. Background Art

[0002] The hydrolysis of ethylene carbonate is an important chemical reaction used to synthesize ethylene glycol, and the reaction of ethylene carbonate hydrolysis to ethylene glycol has important applications in industrial production. Ethylene glycol is an important organic chemical raw material, mainly used in the production of polyester fiber (polyester), polyester resin, antifreeze, lubricant, plasticizer, surfactant, coating, ink, etc.

[0003] In the existing technology, the production process of ethylene carbonate hydrolysis to produce ethylene glycol generally relies on the operation of the distillation kettle. The distillation kettle is the core equipment in this process. It is responsible for separating the complex mixture formed after the reaction, so as to purify and obtain high-quality ethylene glycol products. In order to ensure that the distillation kettle maintains a high degree of stability and safety during continuous operation, it must be firmly fixed with the help of professional fixtures. When connecting the distillation kettle to the fixture, welding or bolting is usually selected. In order to ensure the flexibility of the distillation kettle and the fixture, bolting is generally selected to connect the distillation kettle to the fixture, which is convenient for future maintenance and replacement.

[0004] However, although the existing fixtures perform well in supporting the distillation kettle, their limitations in connection methods cannot be ignored. Although bolt connections provide a relatively flexible disassembly and installation method, in situations where the distillation kettle needs to be frequently disassembled and fixed, the operation process of bolt connections is long and the efficiency of disassembly and fixing is low.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention. On the contrary, the embodiments of the present invention include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0021] The following is a description of the ethylene carbonate hydrolysis ethylene glycol distillation fixture according to an embodiment of the present invention in conjunction with the accompanying drawings.

[0022] The ethylene carbonate hydrolysis ethylene glycol distillation fixing device provided in the embodiment of the utility model can be used to fix the distillation kettle, thereby improving the installation efficiency of the distillation kettle on the fixing device and reducing the workload of the staff.

[0023] like Figure 1-Figure 3 As shown, the ethylene carbonate hydrolysis ethylene glycol distillation fixing device according to the embodiment of the utility model may include a mounting frame 1, an auxiliary component 2, a moving component 3 and a clamping and fixing mechanism 4.

[0024] The auxiliary component 2 is installed on the inner side of the mounting frame 1 .

[0025] It can be understood that the auxiliary component 2 can support the bottom of the distillation kettle to prevent the bottom of the distillation kettle from being suspended in the air and falling.

[0026] The moving components 3 are installed at the four bottom corners of the mounting frame 1 .

[0027] It should be noted that, with the action of the moving assembly 3 , the installation frame 1 and the distillation kettle can be easily moved.

[0028] The clamping and fixing mechanism 4 is installed on the inner top of the mounting frame 1 . The clamping and fixing mechanism 4 may include a clamping plate 41 , a connecting plate 43 , a driving assembly 44 and a pressing assembly 46 .

[0029] It should be noted that the clamping plates 41 and the connecting plates 43 described in the above embodiments are both provided in two groups.

[0030] The clamping plate 41 is arranged on the inner top of the mounting frame 1 .

[0031] The connecting plate 43 is fixedly connected to the clamping plate 41 , and the driving assembly 44 is hinged to the connecting plate 43 .

[0032] Specifically, under the action of the driving assembly 44 , the two groups of connecting plates 43 are squeezed to drive the two groups of clamping plates 41 to approach each other, thereby achieving the effect of fixing and clamping the distillation kettle inside the clamping plates 41 .

[0033] The pressing assembly 46 is installed on the inner side of the clamping plate 41 .

[0034] It can be understood that, under the action of the extrusion assembly 46, the force of the clamping plate 41 to fix the distillation kettle is further increased to ensure the stability of the fixation.

[0035] Specifically, in the actual operation process, when fixing the distillation kettle, the relevant personnel adjust the position of the auxiliary component 2 on the mounting frame 1 according to the height of the distillation kettle, and then drive the driving component 44 to squeeze the connecting plate 43, and drive the two groups of clamps 41 to approach each other under the action of the connecting plate 43, so as to fix the distillation kettle on the inner side of the clamp 41 to the inner side of the mounting frame 1. At the same time, under the action of the squeezing component 46, the force of the clamp 41 to clamp the distillation kettle is further increased to ensure stability during fixation. Subsequently, under the action of the moving component 3, the movement of the mounting frame 1 and the distillation kettle is facilitated, thereby improving the installation efficiency of the distillation kettle on the fixing device and reducing the workload of the staff.

[0036] In one embodiment of the present invention, Figure 1-Figure 2 As shown, the auxiliary assembly 2 may include an auxiliary plate 21 and bolts 22 .

[0039] It should be noted that the screw holes 23 described in the above embodiment are provided in several groups.

[0040] Specifically, the position of the auxiliary plate 21 on the mounting frame 1 can be adjusted by means of the bolts 22 and the screw holes 23 , so as to adapt to distillation kettles of different heights.

[0041] In one embodiment of the present invention, Figure 1-Figure 2 As shown, the moving assembly 3 may include a connecting frame 31 and universal wheels 32 .

[0042] The universal wheels 32 are rotatably mounted at the four corners of the bottom end of the mounting frame 1 through the connecting frame 31 .

[0043] It can be understood that, under the action of the connecting frame 31 , the universal wheel 32 completes the connection with the mounting frame 1 , and the mounting frame 1 is conveniently moved by the universal wheel 32 .

[0046] Among them, the rocker 441 is fixedly connected to the screw 442, and a fixing plate is fixedly connected to the inner side of the mounting frame 1. The screw 442 threadably penetrates the fixing plate. One end of the screw 442 is rotatably connected to the extrusion plate 444 through the rotating shaft 443. The extrusion plate 444 is slidably connected to the transmission rod 445 through a sliding sleeve. The top of the extrusion plate 444 is hinged to the connecting plate 43 through the transmission rod 445.

[0047] It can be understood that under the rotation of the rocker 441, the screw 442 and the rotating shaft 443 squeeze the extrusion plate 444 through the transmission rod 445 to push the connecting plates 43 closer to each other, and under the action of the connecting plates 43, the two sets of clamping plates 41 are brought closer to each other to achieve the effect of fixing the distillation kettle.

[0048] In one embodiment of the present invention, Figure 1-Figure 2 As shown, the pressing assembly 46 may include a spring 461 and a ball 462 .

[0049] The spring 461 is fixedly connected to the inner side of the clamping plate 41 , and the spring 461 is rollingly connected to the ball 462 through a rolling frame, and the ball 462 is arranged through one side of the clamping plate 41 .
