Description

Technical Field

[0001] This application relates to the field of reaction vessels, and more particularly to a filtration device for a mother liquor recovery reaction vessel. Background Technology

[0002] In chemical reactions, mother liquor recovery usually requires the use of a mother liquor recovery reactor.

[0003] In the prior art, the recovered mother liquor is usually added to a reaction vessel, heated by the heating jacket of the reaction vessel, and stirred by a stirring system. The top of the reaction vessel is connected to a distillation / condensation system through a connecting pipe to recover the solvent in the mother liquor.

[0004] The mother liquor usually contains some impurities, which can easily lead to azeotropes during recovery, resulting in a decrease in the purity of the recovered product and interfering with the normal recovery process. It is usually necessary to filter the mother liquor before it is added to the reactor. However, after long-term use, the filter screen tends to accumulate more impurities, resulting in poor filtration. Utility Model Content

[0005] To address the problem of poor filtration efficiency caused by the accumulation of impurities in filter screens after prolonged use, this application provides a filtration device for a mother liquor recovery reactor.

[0006] The filtration device for a mother liquor recovery reactor provided in this application adopts the following technical solution:

A cleaning brush 5 is vertically mounted inside the tank 1 and outside the filter cartridge 3, with one side of the bristles 51 of the cleaning brush 5 adhering to the outer wall of the filter cartridge 3. Water enters the tank 1 through the water inlet pipe 12, is filtered by the filter cartridge 3, and then transported to the reactor 2 via the connecting pipe 11. The rotating component 4 drives the filter cartridge 3 to rotate, and the cleaning brush 5 cleans the outer wall of the filter cartridge 3 as it rotates.

[0035] Reference Figure 2 and Figure 3 The filter cartridge 3 is made of metal filter mesh and has a cylindrical structure. The size of the mesh on its surface is selected according to the size of the impurities to be filtered. The rotating component 4 includes a rotating disk 41, a first gear 42, a second gear 43, and a rotating motor 44. The top of the tank body 1 has coaxially distributed rotating holes 13. The rotating disk 41 is rotatably installed at the rotating holes 13 on the top of the tank body 1. The downward-facing side of the rotating disk 41 is provided with a first slot 52. The filter cartridge 3 and the rotating disk 41 are coaxially inserted and connected at the first slot 52. A rotating ring 14 is coaxially rotatably installed on the bottom wall inside the tank body 1. The upward-facing side of the rotating ring 14 is provided with a second slot 52.

This facilitates the replacement of the cleaning brush 5 when it needs to be replaced.

[0040] Reference Figure 2A drain pipe 15 is provided at the bottom of the tank body 1 and outside the filter cartridge 3. A valve is provided on the drain pipe 15. The drain pipe 15 is used to discharge the impurities filtered out by the filter cartridge 3 into the tank body 1, thereby reducing the accumulation of impurities in the tank body 1 and affecting the filtration effect.

[0041] The implementation principle of the filter device for mother liquor recovery reactor in this application embodiment is as follows: water enters the tank 1 through the water inlet pipe 12, is filtered by the filter cartridge 3, and is then transported to the reactor 2 through the connecting pipe 11. The rotating motor 44 drives the second gear 43 to rotate, the second gear 43 drives the first gear 42 to rotate, which in turn drives the rotating disk 41 to rotate, which in turn drives the filter cartridge 3 to rotate. The cleaning brush 5 cleans the outer peripheral wall of the filter cartridge 3 when it rotates.

[0042] When the cleaning brush 5 needs to be replaced, open the top cover 6 of the tank 1, pull the pin 75 on the cleaning brush 5 to remove it. At this time, the cleaning brush 5 is separated from the mounting bracket 7. Then remove the cleaning brush 5 and replace it. Reinstall it, insert the pin 75 into the slot 52 of the cleaning brush 5 to fix it, and then put the cover 6 back on to complete the replacement.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
