Description

Technical Field

[0001] This utility model relates to the field of C5 resin processing technology, and in particular to a multi-stage filtration extrusion molding device for C5 resin modification. Background Technology

[0002] C5 petroleum resin is a petroleum derivative composed of five-carbon olefins and other hydrocarbons. It is typically a yellow to pale yellow solid with viscous and soft properties. C5 petroleum resin is an important industrial raw material, widely used in adhesives, coatings, printing inks, paints, rubber, and other fields. C5 petroleum resin is produced from olefins generated by the cracking of petroleum or natural gas through fractionation, polymerization, and polymer chemical reactions. Its molecular structure possesses high functionality and active sites, enabling it to perform various functions and properties in different application fields.

[0003] In the process of modifying C5 resin, C5 needs to be extruded. However, the extrusion molding equipment currently in use only has a single-layer filter screen, which makes the filtration effect of the raw materials poor and easily clogs the discharge port. Based on this, this application proposes a multi-stage filtration extrusion molding device for C5 resin modification, which can solve the above problems. Utility Model Content

A telescopic cylinder is installed inside the fixed cylinder, and its output end is installed together with the combined cylinder.

[0010] This utility model has the following advantages: This multi-stage filtration extrusion molding device for C5 resin modification has an outer filter cylinder installed at the discharge port of the extrusion molding machine. Inside the outer filter cylinder, at the front end, a screen cone is installed with its tip facing the discharge port to break up obstructions and perform primary filtration. Inside the outer filter cylinder, in the middle position, an inner screen cylinder is installed with several rod screen holes at its tail. Inside the inner screen cylinder, a reciprocating screen plate is installed. Its movement can change the space inside the inner screen cylinder and squeeze the raw material inside, improving the discharge effect. At the rear end of the outer filter cylinder, a mesh screen plate is installed, which can perform four-stage filtration of the raw material, giving the entire device a four-stage filtration capability and improving the filtration effect.
