Carbon molecular sieve strip extrusion device with rotating type perforated plate

Abstract

The invention discloses a carbon molecular sieve strip extrusion device with a rotating type perforated plate. The device comprises a base. An extrusion barrel is arranged on the base. A screw is arranged inside the extrusion barrel. A feeding pipeline is arranged at the tail of the extrusion barrel, the rotating perorated plate is arranged at the head of the extrusion barrel, a valve is arrangedbetween the rotating type perforated plate and the extrusion barrel, the rotating type perforated plate is fixed to the base through a rotating base, and a positioning base and a positioning clampingblock are arranged below the rotating type perforated plate; a plurality of hole sets are evenly distributed in the rotating type perforated plate, the hole inner diameters of different hole sets aredifferent, protruding blocks corresponding to the hole sets are arranged on the end face, towards the positioning base, of the rotating type perforated plate, and clamping grooves are formed below theprotruding blocks. The device has the advantages of being simple in structure and flexible in production. In addition, the device has the advantage of producing few product bubbles.

Description

Technical field [0001] The invention relates to a forming device, in particular to a carbon molecular sieve extruding device with a rotary porous plate. Background technique [0002] Carbon molecular sieve is a new type of adsorbent developed in the 1970s and is an excellent non-polar carbon material. Carbon molecular sieve is mainly composed of crystalline carbon and amorphous carbon, so it has a highly developed pore structure and special surface characteristics. Due to its special microporous structure and extremely high reaction activity and adsorption enrichment and reaction performance in nano-space, carbon molecular sieves are widely used in various fields such as industrial nitrogen production and hydrogen production, sewage treatment. [0003] The preparation process of carbon molecular sieve includes the addition of binder after the raw material is milled, and then the extruder is used to make a strip-shaped semi-finished product. Existing carbon molecular sieve rod ext...

AI Technical Summary

Problems solved by technology

Existing carbon molecular sieve extruders are usually twin-screw extruders. The structure of this device is relatively complicated, and the corresponding porous plates need to be replaced when producing carbon molecular sieve rods of different diameters, which is time-consuming.

Therefore, the existing carbon molecular sieve extrusion device has the problems of complex structure and insufficient flexibility in production
