Description

Technical Field

[0001] The utility model relates to the field of separation equipment, in particular to a self-cleaning distillation kettle. Background Art

[0002] A distillation kettle is a kettle used for distillation in chemical production, which is used to distill and separate components with different boiling points. By heating a liquid mixture, the low-boiling liquid evaporates first after heating, and the high-boiling liquid evaporates later, so as to realize the separation of liquids with different boiling points. However, after the distillation work lasts for a period of time, due to the particularity of the materials, attachments adsorbed on the inner wall of the kettle will be generated after the distillation reaction. If not cleaned for a long time, the distillation effect will become poor, and regularly opening for cleaning will affect the use stability of the distillation kettle and increase the maintenance cost. Therefore, a self-cleaning distillation kettle is needed. Summary of the Utility Model

[0003] In view of the above-mentioned disadvantages of the prior art, the purpose of the present utility model is to provide a self-cleaning distillation kettle, which is used to solve the problem of cleaning the attachments on the inner wall of the reaction kettle in the prior art.

[0004] To achieve the above purpose and other related purposes, the present utility model provides the following technical solutions:

[0005] A self-cleaning distillation kettle, comprising:

[0006] A kettle body, on which a kettle cover is arranged. A scraper rack is rotatably connected inside the kettle cover, and scrapers are arranged on the scraper rack. When the kettle cover is configured on the kettle body, the scrapers are close to the inner wall of the kettle body;

[0007] A bottom rack is arranged at the bottom inside the kettle body. A knife rack ring is arranged at the bottom of the scraper rack. When the kettle cover is configured on the kettle body, the knife rack ring is sleeved on the bottom rack, and the knife rack ring and the bottom rack are in sliding fit.

[0008] By implementing the above technical solution, a scraper rack is rotatably connected inside the kettle cover, and the inner wall of the kettle body is cleaned by using the scraper rack. Moreover, the scrapers are close to the inner wall of the kettle body, so that the attachments adsorbed on the inner wall of the kettle body can be scraped off. The bottom rack at the bottom inside the kettle body cooperates with the knife rack ring at the bottom of the scraper rack, which can support the scraper rack by using the bottom rack. The sliding fit between the knife rack ring and the bottom rack will not affect the rotation of the scraper rack.

[0009] In an embodiment of the present utility model, the scraper includes two groups of side wall scrapers alternately arranged up and down on the scraper rack, and a bottom scraper arranged at the bottom of the scraper rack according to the shape of the inner wall of the bottom of the kettle body.

[0010] To implement the above technical solution, by alternately arranging two groups of side wall scrapers up and down, the inner side wall surface of the kettle body can be cleaned to ensure the coverage of the entire inner side wall. The bottom scraper arranged at the bottom of the scraper frame according to the shape of the inner wall of the bottom of the kettle body can clean the bottom of the kettle body to ensure the comprehensiveness of the cleaning of the inner wall of the kettle body.

[0011] In an embodiment of the present invention, a discharge port is arranged at the bottom of the kettle body, a discharge seat is arranged at the bottom of the discharge port, a stop valve is connected to the discharge seat in a liftable manner, and a cut-off cavity is arranged in the discharge seat below the stop valve.

[0012] To implement the above technical solution, the arrangement of the discharge port can facilitate the liquid discharge treatment inside the kettle body. By setting the stop valve in cooperation with the cut-off cavity, liquid leakage can be avoided during the liquid discharge treatment. By setting the distance between the top of the stop valve and the bottom of the kettle body as the maximum stroke height of the stop valve rising, the liquid remaining at the discharge port can be reduced to ensure the reaction stability inside the kettle body.

[0013] In an embodiment of the present invention, a heating pipe is arranged at the bottom of the kettle body, the bottom frame is a hollow bottom frame, and the heating pipe passes through the bottom frame and extends into the kettle body.

[0014] To implement the above technical solution, by arranging a heating pipe at the bottom of the kettle body, it is convenient to use the heating pipe to heat the liquid inside the kettle body.

[0015] In an embodiment of the present invention, two groups of heating pipes are arranged at the bottom of the kettle body, and the two groups of heating pipes are independently externally connected to power supplies. The lengths of the parts of the two groups of heating pipes extending into the kettle body are set to be less than half of the height of the kettle body.

[0016] To implement the above technical solution, by independently externally connecting the two groups of heating pipes to power supplies, when one group of heating pipes is damaged, the other group of heating pipes can continue to complete the heating work to ensure the stability of the distillation treatment. By setting the lengths of the parts of the two groups of heating pipes extending into the kettle body to be less than half of the height of the kettle body, a distillation space can be reserved at the upper side of the original liquid injected into the kettle body, maximizing the heat transfer efficiency of the heating pipes to the original liquid inside the kettle body.

[0017] In an embodiment of the present invention, a sealing gasket is arranged at the connection end of the kettle cover and the kettle body, and a liquid inlet and a gas outlet are arranged on the kettle cover.

[0018] To implement the above technical solution, the sealing gasket can ensure the sealing reliability and stability between the kettle cover and the kettle body. The liquid inlet and gas outlet on the kettle cover can improve the use convenience without the need to open a liquid inlet on the kettle body to ensure the use stability and reliability of the kettle body.

[0019] As described above, a self-cleaning distillation kettle of the present utility model has the following beneficial effects: By rotatably connecting a scraper frame inside the kettle cover, the inner wall of the kettle body is cleaned by the scraper frame, and the scraper is close to the inner wall of the kettle body, so that the attached substances adsorbed on the inner wall of the kettle body can be scraped off. The bottom frame at the bottom side inside the kettle body cooperates with the knife rest ring at the bottom of the scraper frame, and the bottom frame can support the scraper frame, and the sliding fit between the knife rest ring and the bottom frame will not affect the rotation of the scraper frame.
