[0022] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0023] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0024] In an exemplary embodiment, Figure 1-3 As shown, this embodiment provides a methanol removal kettle, which includes a vertically arranged kettle body 1, the upper end of the kettle body 1 is fixedly connected with a feed pipe 2 connected thereto, the lower end is fixedly connected with a discharge pipe 3 connected thereto, and a heating component is also arranged in the kettle body 1; a cover body 4 is fixedly connected to the upper end of the kettle body 1, the lower end of the cover body 4 is open and a plurality of liquid partition plates 5 are obliquely arranged therein, a plurality of liquid partition holes 6 are also penetrated on the liquid partition plates 5, a guide pipe 7 is also fixedly connected to the cover body 4 and the guide pipe 7 is fixedly passed through the kettle body 1 and extends outside the kettle body 1, the guide pipe 7 is connected with the cover body 4 and the connection point is located between the higher end and the lower end of the liquid partition plate 5.

[0025] In the above embodiment, a cover body 4 is arranged in the kettle body 1, and the generated methanol vapor first enters the cover body 4, and then passes through the liquid isolation hole 6 on the liquid isolation plate 5, and then enters the outlet pipe 7 for discharge. The liquid isolation plate 5 arranged in this way can block part of the liquid material, reduce the amount of material in the methanol vapor, thereby reducing the loss of the material, and solves the problem in the prior art that more materials are carried into the outlet pipe 7 by the methanol vapor, thereby causing a large degree of material loss; specifically, similar to the prior art, the mixed liquid material (the material mixed with methanol) is introduced into the kettle body 1 through the feed pipe 2, and the heating component heats the material, so that the methanol therein generates methanol vapor, which enters the cover body 4 upward through the lower end of the cover body 4, and the inclined liquid isolation plate 5 is arranged. Methanol vapor is prevented from directly entering the outlet pipe 7, and first passes through the liquid isolation hole 6 on the liquid isolation plate 5 and then enters the outlet pipe 7. During the process, the liquid isolation plate 5 can allow part of the liquid material to adhere, and then return downward from the lower end of the liquid isolation plate 5 to the material in the kettle body 1, while the methanol vapor smoothly enters the outlet pipe 7, thereby reducing the material content in the methanol vapor; wherein, the liquid isolation plate 5 is set to be inclined, which can provide a larger area for material attachment and the material in the methanol vapor is more likely to contact with the liquid isolation plate 5 during the rising process and efficiently adhere to the liquid isolation plate 5. More specifically, the connection between the outlet pipe 7 and the cover body 4 is set on the side of the cover body 4, so that the methanol vapor needs to be discharged from the side, which can also prevent the methanol vapor from directly entering and carrying part of the material.

[0026] In a further exemplary embodiment, Figure 1-3 As shown, a driving motor 8 is fixedly mounted on the outer top surface of the kettle body 1, a driving shaft 9 is coaxially arranged inside the kettle body 1, and the upper end of the driving shaft 9 is rotated to extend outside the kettle body 1 and connected to the driving motor 8, and a stirring blade 10 is fixedly connected to the driving shaft 9. The driving motor 8 can drive the driving shaft 9 inside the kettle body 1 to rotate, thereby driving the stirring blade 10 to stir the material, which can improve the efficiency of heating the material, and at the same time, the generated methanol vapor can be separated from the material more quickly and move upward into the cover body 4;

[0027] Furthermore, the heating component includes a coil 11 spirally wrapped around the outside of the drive shaft 9, and both ends of the coil 11 are fixedly extended outside the kettle body 1. Specifically, the upper end of the coil 11 is used to introduce high-temperature water vapor, and then the material is heated through the coil 11 in the kettle body 1, and then discharged through the lower end of the coil 11, thereby achieving the purpose of heating the material; more specifically, the stirring blade 10 is located below the coil 11, so that the stirring blade 10 and the coil 11 can be prevented from colliding with each other and causing damage to the coil 11 or the stirring blade 10.

[0028] In a more detailed exemplary embodiment, Figure 1-3As shown, the feed pipe 2 extends vertically to the lower end of the kettle body 1 and is located in the spiral where the coil 11 is located. The two are not arranged in contact with each other. In actual operation, the material is submerged in the lower end of the feed pipe 2, which can prevent the generated methanol vapor from accidentally entering the feed pipe 2 and causing recoil.

[0029] In a more detailed exemplary embodiment, Figure 1 , 2 As shown, the cover body 4 is also fixedly connected to a through cylinder 12 surrounding the outside of the drive shaft 9, and the through cylinder 12 is set apart from the drive shaft 9, so that the cover body 4 can be set just above the kettle body 1, covering a larger range above the inside of the kettle body 1 for methanol vapor to enter and then be discharged. The through cylinder 12 is provided to surround the outside of the drive shaft 9 to avoid affecting the normal operation of the drive shaft 9.

[0030] In a further detailed exemplary embodiment, Figure 2 As shown, the top surface of the cover body 4 is an arc with one end higher and the other end lower, and the higher ends of all the liquid-isolating plates 5 are fixedly connected to the top surface of the cover body 4, respectively, so that the inner top surface of the cover body 4 can also be used for material attachment, and the material can be diverted toward the higher end of the adjacent liquid-isolating plate 5, or from the lower end of the top surface, to prevent more material from entering the outlet pipe 7 with the methanol vapor. Specifically, the outlet pipe 7 is close to the higher end of the top surface of the cover body 4.

[0031] In a further detailed exemplary embodiment, Figure 1-3 As shown, the inner diameter of one end of the liquid barrier hole 6 facing the connection point is larger than that of the other end, that is, the methanol vapor contacts the smaller end first, and the corresponding area for material attachment is larger, and the effect of intercepting the material is better. Furthermore, the liquid barrier hole 6 is inclined and the end facing the connection point is higher. In the process of moving upward, the methanol vapor connects with the liquid barrier plate 5 and enters through one end of the smaller liquid barrier hole 6. More materials adhere to the liquid barrier plate 5, and some materials pass through the liquid barrier hole 6 with the methanol vapor. Multiple liquid barrier plates 5 are also provided, so that at least one interception is required to enter the outlet pipe 7. At the same time, the opening of the liquid barrier hole 6 on the higher side of the liquid barrier plate 5 is larger. In the process of the upper material moving downward, more will enter the liquid barrier hole 6, and then flow to the lower side, and then flow obliquely downward to leave the liquid barrier plate 5 and return to the material below.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
