Description

TECHNICAL FIELD

[0002] Carbon molecular sieve is a new type of adsorbent, which is an excellent non-polar carbon material. In the production process of carbon molecular sieve, the raw material of carbon molecular sieve needs to be crushed and ground first, and then screened.

[0003] Patent network discloses a carbon molecular sieve preparation device (publication number: CN221208199U). This existing technology uses a sieve plate to screen the ground carbon molecular sieve raw material. The carbon molecular sieve that meets the requirements is moved along the inclined plate through the sieve plate and falls into the collection box on the left. The carbon molecular sieve with larger particles cannot pass through the sieve plate along the inclined direction of the sieve plate and enters the collection box on the right. This technology facilitates the screening of ground carbon molecular sieve raw material during the preparation of carbon molecular sieve.

Since large and small particles are mixed together, it can cause large particles to block the sieve holes of the sieve plate, reducing the screening efficiency.
