Description

Technical Field

[0001] This utility model relates to the field of heavy alkylbenzene sulfonic acid extraction technology, specifically a continuous circulating extraction device for heavy alkylbenzene sulfonic acid. Background Technology

[0002] Heavy alkylbenzene sulfonic acid is a chemical substance, usually a reddish-brown viscous liquid. It is mainly produced by the sulfonation and neutralization reaction of heavy alkylbenzenes. It is easily soluble in water and slightly soluble in organic solvents such as ethanol and ether. It remains stable in acid, alkali and salt environments, so it is widely used in many fields, especially in some care products and stain removal products, and has good foaming and cleaning abilities.

[0003] Heavy alkylbenzene sulfonic acid generally requires specialized extraction equipment to obtain. When using it, the liquid after heating and mixing the reaction requires a special cooling mechanism through condenser tubes for cooling. Water flowing into the pipes needs to be in contact for a period of time to cool down, and the generated gas is also easy to disperse. This not only results in high operating costs but also poor cooling efficiency. Furthermore, traditional extraction equipment involves complicated steps, especially the setup and connection of various test tubes and deheating and cooling equipment, some of which still require manual work, making it less convenient to use.

[0004] To address these issues, we propose a continuous cyclic extraction device for heavy alkylbenzene sulfonic acid. Utility Model Content

[0033] Specifically, the extraction and mixing chamber 1 and the heating mechanism 3 are included. A collection and separation box 2 is installed at the bottom of the extraction and mixing chamber 1, and a drive mechanism 6 is installed at the top center of the extraction and mixing chamber 1. A partitioned installation slot 14 is opened in the inner top of the extraction and mixing chamber 1. The partitioned installation slot 14 is mainly for facilitating the installation of various mechanisms and also for facilitating the flow of gas. The output end of the drive mechanism 6 is located inside the partitioned installation slot 14 and is connected to a conical disc gear 20. Two sets of bevel gears 21 are symmetrically meshed on both sides of the top of the conical disc gear 20. One end of each set of bevel gears 21 is connected to a transmission rod 22. The top side of the extraction and mixing chamber 1 is located on the left and right sides of the partitioned installation slot 14. The extended connection has two sets of extended air guide boxes 9. The extended air guide boxes 9 are mainly for facilitating the installation of one end of the transmission rod 22 and the fan blades 23 and 24. The outer side of one end of the transmission rod 22 is located inside the two sets of extended air guide boxes 9, and the fan blades 23 and 24 are respectively fitted inside. Two sets of air guide connecting pipes 10 are symmetrically installed between the bottom of the two sets of extended air guide boxes 9 and the top of the collection and separation box 2. A drain valve pipe 15 is installed through the bottom of the extraction mixing box 1 and the middle of the top of the collection and separation box 2. The drain valve pipe 15 is mainly a discharge pipe with a control valve installed in the middle, which can be controlled to open and close externally. The bottom end of the drain valve pipe 15 is located in the collection and separation box. A multi-head nozzle 11 is connected to the top of the inner part of the collection and separation box 2. A perforated ventilation mesh frame 16 is installed on the inner top side of the collection and separation box 2 at the bottom of the multi-head nozzle 11. The left and right sides of the perforated ventilation mesh frame 16 are respectively connected to two sets of air guide pipes 10. Two sets of installation partition plates 25 are symmetrically installed on both sides of the inner side of the partition installation slot 14. The transmission rod 22 is rotatably installed through the middle of the installation partition plate 25.

[0037] The working principle and usage process of this utility model are as follows: First, the raw material to be extracted is injected into the extraction mixing chamber 1 through the injection pipe 4. Then, reaction additives are intermittently added into the extraction mixing chamber 1 through the feeding pipe 5. Simultaneously, the drive mechanism 6 and heating mechanism 3 are turned on, causing the connecting rotating rod 12 to rotate and the stirring blade 13 to continuously stir and mix the heated liquid inside the extraction mixing chamber 1. After sufficient reaction, the drain valve pipe 15 is opened, allowing the liquid to be dispersed and sprayed into the top of the collection and separation box 2 through the multi-head spray pipe 11. The liquid is sprayed onto the porous ventilation mesh frame 16, and the connecting rod 12 drives the conical disc gear 20 to rotate, so that the two sets of conical gears 21 mesh and drive, and the two sets of transmission rods 22 drive the fan blades 23 and the exhaust fan blades 24 to rotate simultaneously. The liquid is injected and extracted into the porous ventilation mesh frame 16 through the two sets of extended air guide boxes 9 and the two sets of air guide connecting pipes 10, and the liquid is cooled in this cycle. After cooling, the liquid continues to be screened and filtered by the filter cloth 19 and the concave filter screen plate 17, and finally falls into the collection box 18 for unified collection.
