Pelletizing-screening integrated equipment used for carbon molecular sieve raw materials

Abstract

The invention discloses pelletizing-screening integrated equipment used for carbon molecular sieve raw materials. The pelletizing-screening integrated equipment comprises supporting legs, wherein a pelletizing device is fixedly arranged at the upper ends of the supporting legs. The pelletizing-screening integrated equipment is characterized in that the pelletizing device comprises a fixed housing and a rotary housing, wherein the rotary housing and the fixed housing are cylindrical; the rotary housing is positioned inside the fixed housing; the left end of the rotary housing is fixedly connected with a charge supporting post; a charge channel which communicates with the inner part of the rotary housing is arranged in a charge supporting rod; a rotary rod is fixedly connected at the right end of the rotary housing; the charge supporting rod and the rotary rod penetrate through the fixed housing; and the other end of the rotary rod is connected with a power device. The pelletizing-screening integrated equipment has the beneficial effects of grinding the materials by utilizing a grinding ball, and further has a screening function in a processing process; and a second screen in a screening device can move left and right, so that vibration amplitude of the second screen is great, and screening effect is better than that of a conventional screening device.

Description

technical field [0001] The invention relates to the technical field of carbon molecular sieve production, in particular to an integrated equipment for granulation and screening of carbon molecular sieve raw materials. Background technique [0002] Carbon molecular sieve is a new type of adsorbent developed in the 1970s. It is an excellent non-polar carbon material. Carbon molecular sieves (Carbon Molecular Sieves, CMS) for nitrogen production are used to separate air and enrich nitrogen. Compared with the traditional cryogenic high-pressure nitrogen process, the low-pressure nitrogen process has the advantages of less investment cost, fast nitrogen production speed, and low nitrogen cost. Therefore, it is currently the preferred nitrogen-rich adsorbent for pressure swing adsorption (P.S.A) air separation in engineering circles. It is widely used in heat treatment, transportation and storage. [0003] The existing carbon molecular sieve preparation method sequentially inclu...

Problems solved by technology

[0004] In the prior art, the granulation of carbon molecular sieves is carried out by a crusher for granulation and crushing. However, in view of the limited crushing effect, there will inevitably be some raw materials that have not been completely crushed, so additional screening work is required to increase the granulation. The workload is large, and the current screening device generally performs vibration screening on the screen, and its vibration amplitude is small, so it is difficult to form a good screening effect
