AI Technical Summary

Technical Problem

When using a fixed plate for pressurization in the existing pentaerythritol mother liquor extraction tower, the separation of the sieve holes and the mixing port causes pressure factors in the mixing tank to cause squeezing, affecting the safety of the equipment.

Method used

The system employs a feed pipe and pressure plate structure. A hydraulic cylinder drives a linkage rod to move the pressure plate in reciprocating motion, thereby achieving the circulation and pressurization of the raw material in the mixing tank. Combined with the extract phase and raffinate phase in the main body of the extraction tower, the target product is separated using liquid-liquid extraction technology.

Benefits of technology

The safety and efficiency of the extraction tower were improved, achieving efficient separation of the target product and recycling of the mother liquor, thus enhancing the stability and safety of the device.

Abstract

The utility model relates to the technical field of biochemical manufacturing equipment, in particular to a pentaerythritol mother liquor extraction tower. Comprising a tower body assembly, a feeding assembly and a pressurizing assembly, the tower body assembly comprises an extraction tower main body and a first assembly ring, the feeding assembly comprises a feeding tower, the pressurizing assembly comprises a hydraulic cylinder, the lower end of the feeding tower is connected with a material guide pipe, the output end of the hydraulic cylinder is connected with a linkage rod, the outer wall of the linkage rod is connected with a sleeving pipe, and the sleeving pipe is connected with a first assembly ring. The outer wall, away from the linkage rod, of the sleeving pipe is connected with a pressurizing plate. When raw materials are added into the material guiding pipe from the material guiding pipe, the hydraulic cylinder runs to drive the pressurizing plate to do reciprocating motion through the linkage rod, the raw materials in the material guiding pipe are pressurized in the process, the raw materials in the material guiding pipe flow out through a mixing groove formed in the pressurizing plate, and circulating pressurizing is carried out through reciprocating motion of the pressurizing plate; furthermore, after the raw materials flow into the extraction tower main body, the target product is separated from the mother liquor.
