Description

Technical Field

[0001] The utility model relates to the technical field of equipment for activated carbon production, in particular to a screening mechanism for a material crushing and screening device for activated carbon production. Background Art

[0002] During the production process of activated carbon, two activation processes are required. The materials after being activated in a primary activation furnace are crushed and screened by corresponding crushing and screening equipment and then sent to a secondary activation furnace for secondary activation processing.

[0003] Among them, vibrating screening machines are mostly used for screening equipment, which includes a screening box body equipped with a driving motor, as well as a screening plate and an aggregate plate fixedly installed on the screening box body. The materials screened by the screening plate are collected through the discharge end of the aggregate plate, while the slag materials that cannot pass through the screening plate are directly collected through the discharge end of the screening plate. Subsequently, the materials that have completed the screening are sent to the secondary activation furnace for secondary activation processing, and the slag materials that cannot pass through the screening plate are re-fed to the corresponding crushing mechanism for re-crushing operations. Due to the large kinetic energy of the vibrating screening machine, it is difficult to configure other auxiliary mechanisms besides the vibrating screening operation, resulting in a relatively single use function of the equipment and a low adaptability of the equipment in use.

Specific embodiments

[0027] For the convenience of those skilled in the art to understand, the structure of the present invention will be further described in detail below in conjunction with the attached drawings:

[0028] Reference Figures 1-5 , a screening mechanism for a material crushing and screening device for activated carbon production, comprising:

[0029] A screening box body 1, a set of corresponding vibration motors 2 are fixedly installed at the bottom of the screening box body 1, a mounting hole 101 is arranged at the upper part of one side of the screening box body 1, and a discharge pipe 102 is arranged at the lower part of the other side of the screening box body 1;

[0030] A broken material screening tank 3 is arranged at the mounting hole 101 of the screening box body 1 at intervals. A feeding hopper 4 is arranged at the top of the broken material screening tank 3. A plurality of corresponding first filter holes 301 are evenly distributed at the bottom of the broken material screening tank 3. A corresponding discharge pipe 5 is connected downward at the center of the bottom of the broken material screening tank 3, and a corresponding discharge valve 6 is fixedly installed on the discharge pipe 5;

[0031] The secondary sieving mechanism 7 includes a sieving container 701 connected to the bottom side of the discharge pipe 5 through an elastic corrugated pipe 705. A plurality of corresponding second filtering holes 7011 are evenly distributed on the sieving container 701. The bottom of the sieving container 701 is provided with a connecting and discharging pipe 702 penetrating and installed on the sieving box body 1. The bottom side of the connecting and discharging pipe 702 is inclined downward with a corresponding discharging guide pipe 703. The upper end of the connecting and discharging pipe 702 is movably installed with a corresponding fixing plug 704 in an interference fit manner. The fixing plug 704 is driven by a corresponding discharging driving mechanism 8. When the discharging driving mechanism 8 drives the fixing plug 704 to move to the bottom side of the discharging guide pipe 703, the materials in the sieving container 701 are discharged along the discharging guide pipe 703.

[0032] The sieving container 701 of the secondary sieving mechanism 7 of the present utility model is rigidly connected to the sieving box body 1 through the connecting and discharging pipe 702, so as to ensure the transmission of vibration, make the sieving container 701 in a continuous vibration state, facilitate the smooth progress of the sieving operation. The sieved materials are discharged and collected through the discharge pipe 102 of the sieving box body 1, while the slag materials that cannot complete the sieving are discharged and collected through the discharging guide pipe 703; on this basis, the present utility model is further provided with a crushing and sieving tank 3, which is arranged at intervals on the mounting hole 101 of the sieving box body 1, and the bottom is connected to the sieving container 701 of the secondary sieving mechanism 7 through an elastic corrugated pipe 705, so that the crushing and sieving tank 3 can be effectively set on the basis of not affecting the vibration sieving operation of the materials, and the first filtering holes 301 are set on the crushing and sieving tank 3. In this way, the material crushing mechanism 14 can be arranged in the crushing and sieving tank 3 to initially complete the primary sieving operation of the materials while crushing the materials.

In this way, it can not only assist in improving the dust removal effect, but also prevent dust from flying at the gap between the crushing and screening tank 3 and the screening box body 1, thus further ensuring the practical effect of the present utility model.
