[0002] A still is a piece of equipment used in the distillation process of chemical materials. Its main function is to heat the chemical materials to cause them to distill and vaporize, and to output the vaporized gas. The heating methods of the still are divided into direct heating and flue gas heating. The corresponding heating method can be selected according to the boiling point of the required distillate.

[0003] The existing distillation kettle is generally equipped with a set of stirring equipment inside, so that the chemical material is stirred during the heating process, thereby improving the uniformity of the heating of the material. In the process of distilling the chemical material mixture, as the internal water is continuously evaporated, the liquid level of the chemical material will continue to decrease, which may cause some chemical materials to adhere to the inner wall of the distillation kettle. In the prior art, a scraper is generally installed on the stirring rod of the stirring equipment, and the scraper is slid against the inner wall of the distillation kettle, so that the material adhered to the inner wall can be scraped off during the stirring of the chemical material by the stirring rod. Although this scraping method can solve the problem of material adhering to the inner wall, as the scraper and the inner wall of the distillation kettle slide and rub for a long time, certain wear and debris will inevitably occur. When a gap is generated between the scraper and the inner wall of the distillation kettle, the scraping effect of the material may be affected. In view of this, the present utility model is specially proposed. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a chemical material distillation kettle which can overcome the above problems or at least partially solve the above problems.

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0020] Embodiment 1:

[0021] Reference Figure 1-Figure 4 A chemical material distillation kettle comprises a kettle body 1 and a kettle cover 2, wherein the kettle cover 2 covers the opening at the upper end of the kettle body 1, and a feed pipe 201 and a pressure relief pipe 202 are symmetrically arranged on the kettle cover 2. The kettle cover 2 also comprises: a motor 3 fixedly mounted on the kettle cover 2; a rotating shaft 301 rotating in the kettle body 1, and the upper end of which is fixedly connected to the output end of the motor 3; a nozzle 306 equidistantly arranged in the kettle body 1, and a plurality of nozzles 307 are connected to one side of the nozzle 306; a gas supply telescopic component for conveying gas into the nozzle 306, and the two ends of the gas supply telescopic component are respectively fixedly connected to the rotating shaft 301 and the nozzle 306; a driving component for controlling the telescopic gas supply component to be telescopic, which is mounted on the kettle body 1 and the nozzle 306.

[0022] The air supply telescopic assembly includes an air cylinder 302, a piston rod 303 with a piston, and a tensioning spring 304. The air cylinder 302 is equidistantly fixedly connected to the side of the nozzle 306 close to the rotating shaft 301, the piston rod 303 is slidably connected in the air cylinder 302, the tensioning spring 304 is arranged in the air cylinder 302, and the two ends are respectively fixedly connected to the air cylinder 302 and the piston rod 303, the air outlet of the air cylinder 302 and the air inlet of the nozzle 306 are connected to each other, and multiple air cylinders 302 are connected to each other through a connecting air pipe 305, and a one-way valve is respectively provided in the air outlet of the air cylinder 302 and the air inlet of the connecting air pipe 305 located at the uppermost end.

[0023] The driving assembly includes an arc column 102 and a roller 308 . The arc column 102 is fixedly connected to the inner wall of the kettle body 1 at equidistant intervals in a circle. The roller 308 is installed on the side of the nozzle 306 away from the rotating shaft 301 and rolls against the inner wall of the kettle body 1 .

[0024] When it is necessary to distill the chemical materials, first add the mixed solution of the materials into the kettle body 1 through the feed pipe 201, and then start the heating device in the kettle body 1 to heat and distill the mixed solution of the materials. In order to improve the uniformity of the heated distillation of the mixed solution of the materials, the motor 3 can be started at this time, and the motor 3 will drive the rotating shaft 301 to rotate, and the rotating shaft 301 will drive the piston rod 303 and the gas cylinder 302 to rotate, so that the materials can be stirred and the uniformity of the heating of the materials can be improved.

[0025] After the material is distilled for a period of time, the liquid level of the material will drop, and some of the material may adhere to the side wall of the kettle body 1 above the liquid surface, thereby separating from the material mixed solution, resulting in the inability to fully utilize the part of the material, causing certain waste. Through the arrangement of the arc column 102 and the roller 308, when the roller 308 is driven by the air cylinder 302 to roll on the side wall of the kettle body 1 through the nozzle 306, when the roller 308 contacts the arc column 102, the roller 308 will drive the air cylinder 302 to roll on the side wall of the kettle body 1 under the action of the arc column 102. 2 moves toward one side of the rotating shaft 301, so that with the cooperation of the piston rod 303, the gas stored in the gas cylinder 302 can be delivered to the nozzle 306. When the pressure value of the gas pressure in the nozzle 306 is greater than the pressure value of the nozzle 307, the gas in the nozzle 306 will be sprayed out through the nozzle 307, and then the gas will be sprayed to the side wall of the kettle body 1 through the nozzle 307, so that the material attached to the side wall can be blown into the material mixed solution, which effectively improves the uniformity of the distillation of the material mixed solution and the utilization rate of the material.

[0026] Embodiment 2:

[0027] Reference Figure 1-Figure 4 , a chemical material distillation kettle, is basically the same as Example 1, and further: the gas cylinder 302 and the piston rod 303 are sealed and slidably connected by a seal 309. The setting of the seal 309 can improve the sealing between the gas cylinder 302 and the piston rod 303, and prevent the material from entering the gas cylinder 302 through the gap, affecting the waste of material and the normal use of the gas supply telescopic component.

[0028] A transparent plate 101 is fixedly connected to the kettle body 1. The transparent plate 101 is arranged to facilitate the staff to check the distillation status of the material inside the kettle body 1 through the transparent plate 101, thereby providing convenience for the staff.

[0029] The nozzles 307 are evenly spaced apart on one side of the nozzle 306. By evenly spaced apart installation of a plurality of nozzles 307 on one side of the nozzle 306, when the gas in the nozzle 306 is ejected through the nozzles 307, it can not only blow away the material attached to the inner wall of the kettle body 1, but also inject gas into the material so as to better heat the material.
