Description

Technical Field

[0001] The utility model relates to the technical field of petroleum resin purification equipment, in particular to a separation and purification device for petroleum resin. Background Art

[0002] Petroleum resin is a resin product obtained from the petrochemical process, with good thermal stability, chemical stability and adhesion properties. It is widely used in the fields of rubber, coatings, adhesives, inks, etc. As a tackifier, softening agent or active filler, indicators such as the softening point, color and acid value of petroleum resin are important parameters to measure its quality.

[0003] In the existing petroleum resin separation and purification device, when the purification device is working, during the purification process of the polymer, the material is prone to accumulate at the bottom of the tank. After purification, the solid polymer in the tank cannot be directly discharged. Only by adding a solvent can it be transformed into a liquid state and discharged from the discharge port at the bottom of the washing kettle, which increases the complexity of the operation and reduces the efficiency of the entire purification process. Based on these problems, Chinese Patent CN220657549U discloses a separation and purification device for petroleum resin polymer. By clockwise rotating the crank to drive the gear ring and the tank to rotate counterclockwise, the purified and separated petroleum resin polymer is discharged through the discharge port. The stirring shaft drives the stirring blades to stir the petroleum resin polymer along the inner wall of the reaction chamber to ensure that the petroleum resin polymer can react fully, separate the impurities in the petroleum resin polymer, and improve the purification efficiency of the polymer.

[0004] In the separation and purification device of this petroleum resin, only a set of simple discharge port structures are provided, and the purified liquid and solid impurities in the polymer cannot be separated. Therefore, the purified liquid and solid impurities in this device will be discharged from the discharge port at the same time, and the staff needs to recover the purified liquid and solid impurities and perform the separation operation again. This process not only wastes the time of the staff, but also affects the progress of the purification work. Summary of the Utility Model
