Graded screening device for granulated and shaped granular activated carbon

Abstract

The invention relates to the field of activated carbon screening processing, in particular to a graded screening device for granulated and shaped granular activated carbon. The graded screening device for the granulated and shaped granular activated carbon comprises a base, a screening mechanism, a reciprocating mechanism and a receiving mechanism, wherein the screening mechanism is arranged on the upper end face of the base; the reciprocating mechanism is connected onto the screening mechanism; the lower end of the reciprocating mechanism is mounted on the base; and the receiving mechanism is arranged on the upper end face of the base and located on the front side of the screening mechanism. The graded screening device for the granulated and shaped granular activated carbon provided by the invention can solve the following problems in the process of classifying and screening the granular activated carbon by adopting an activated carbon vibration classifying screen in the prior art: a horizontally arranged screening net is easy to cause that large granular activated carbon subjected to classifying and screening is difficult to discharge outwards, a mechanism for cleaning screening net holes does not exist, and the graded screening effect and the graded screening efficiency of the granular activated carbon are reduced; and the granular activated carbon which cannot be screened can be cleaned only by detaching the screening net of the activated carbon vibration classifying screen.

Description

Technical field [0001] The present invention relates to activated carbon screening processing, and more particularly relates to a granular activated carbon granulated after setting the screening device classification. Background technique [0002] The prior art activated carbon is usually activated carbon particles vibrating sieve classifier classifying sieve, but generally there is a problem in this process: 1 activated carbon prior circular vibrating sieve Sieve mesh is disposed horizontally, so granular activated carbon during the movement path sieved small, it is difficult to discharge outwardly through the activated carbon particles larger after classification screening, easily lead to granular activated carbon to be discharged outwardly sieving mesh clogging, and the existing no activated carbon mesh sieve cleaning mechanism for vibrating the sieve classification, resulting in clogged mesh sieve reduces the effectiveness and efficiency of the sieved granular activated carbo...

AI Technical Summary

Problems solved by technology

[0002] The prior art usually uses activated carbon vibrating grading sieves to carry out classification and screening of granular activated carbon, but there are usually the following problems in this process: 1. The circular screen mesh of the existing activated carbon vibrating grading sieves is horizontally set, so granular activated carbon The moving path in the process of being screened is small, and it is difficult to discharge the larger granular activated carbon after grading and screening, which will easily cause the granular activated carbon to be discharged to block the screening mesh, and the existing There is no mechanism to clean the screen mesh in the activated carbon vibrating grading screen, which leads to the clogged screen mesh reducing the effect and efficiency of screening granular activated carbon

[0003] 2. During the sieving process of granular activated carbon, there will be some granular activated carbon that cannot pass through the lower sieve mesh. When there is an appropriate amount of granular activated carbon of suitable size stored on the sieve net, the activated carbon needs to be vibrated and classified. The screens of the sieves can only be cleaned by dismantling them, but this process is cumbersome and reduces the efficiency of discharging the appropriate size granular activated carbon from the screening area
