Description

Technical Field

[0001] The utility model belongs to the technical field of activated carbon conveying, and specifically refers to an activated carbon lifting and conveying device. Background Art

It has a developed pore structure, a large specific surface area, and rich surface chemical groups, and is a carbon material with strong specific adsorption ability. During the processing of activated carbon, it is often necessary to transport granular activated carbon to a high place. When the existing conveying devices are in use, they cannot remove the impurities and fragments mixed in the activated carbon. Moreover, due to the pores on the surface of the activated carbon, it is easily affected by moisture and invalidated or adhered with dust during transportation, reducing the adsorption performance of the activated carbon and affecting the quality of the finished product.

[0037] Working principle and workflow:

[0038] When in use, the device is pushed to the desired site by the moving wheel 11. According to the required conveying height, the telescopic motor 310 is started to adjust the height of the electric telescopic frame 32. The fixed shaft 36 drives the second follower wheel 38 to rise or fall, and the conveyor belt 39 at the second follower wheel 38 rises or falls. During the adjustment period, the telescopic plate 212 and the tensioning mechanism 24 are adaptively adjusted. The telescopic plate 212 slides in the limiting side plate 211. The tensioning wheel 242 adaptively squeezes and fits the conveyor belt 39 under the elastic action of the tensioning spring 244. Since the total length of the conveyor belt 39 is fixed, when the second follower wheel 38 rises, the tensioning wheel 2 The conveyor belt 39 at 42 squeezes the tensioning wheel 242, the tensioning spring 244 is compressed, and the telescopic connecting rod 241 contracts; when the second follower wheel 38 is lowered, the conveyor belt 39 is relaxed, and the tensioning spring 244 pushes the tensioning wheel 242 to fit the conveyor belt 39, so that the conveyor belt 39 is always in a taut state; at the same time, the limiting side plate 211 rotates accordingly, and the limiting side plate 211 drives the limiting ring 224 to move up and down during the rotation, and the limiting ring 224 supports the toggle block 223 to follow the movement, so that the toggle block 223 is always on the outside of the limiting side plate 211, ensuring that the driving force of the toggle block 223 acts on the limiting side plate 211.

[0039] Subsequently, the activated carbon is placed above the conveyor belt 39 at the first follower wheel 37, and the feeding mechanism is used to continuously feed the material. The main power motor 33, the rotating motor 221 and the blowing pump 231 are started respectively. The main power motor 33 drives the main shaft 34 to rotate, and then drives the first follower wheel 37 to rotate through the positioning block 35. Driven by the conveyor belt 39, the second follower wheel 38 and the tensioning wheel 242 follow the rotation; the rotating motor 221 drives the sliding telescopic column 222 to rotate, and then drives the toggle block 223 at the upper end thereof to rotate, and the symmetrical toggle During the rotation process, the block 223 pushes the impurity removal cover 21 as a whole to slide back and forth on the main rotating shaft 34 and the fixed shaft 36, and the connection between the limiting ring 224 and the limiting side plate 211 is adaptively extended and retracted, thereby driving the first follower rotating wheel 37 on the inner side of the limiting side plate 211 to slide on the main rotating shaft 34, and the positioning block 35 slides in the positioning groove 371, and at the same time drives the second follower rotating wheel 38 on the inner side of the telescopic plate 212 to slide on the fixed shaft 36. During this period, the screening spring 216 provides buffering force and resilience, thereby intensifying the screening effect of the impurity removal cover 21;

[0040] The activated carbon falling on the conveyor belt 39 is spread out under the overall sieving movement of the impurity removal cover 21, and the impurities and broken particles mixed therein are filtered out through the sieve holes on the conveyor belt 39, and the filtered impurities and broken particles fall onto the ash collecting plate 213, and roll down from the transition cavity 215 on the folded ash collecting plate 213 to the impurity collecting cavity 214 or directly fall into the impurity collecting cavity 214. The supporting plate 391 ensures that the activated carbon does not slide down during transportation, and the limiting side plates 211 on both sides also ensure that the activated carbon does not fall off;

[0041] The dust suppression cover 23 prevents the activated carbon from raising dust during transportation. At the same time, the blowing pump 231 supplies air to the blowing pipe 232. Hot air is used when necessary. The air flow is blown out from the blowing port. On the one hand, it accelerates dust reduction and blows the dust into the collecting chamber 214. On the other hand, it keeps the activated carbon dry to prevent the activated carbon from getting damp or adhering to dust, which would reduce its adsorption performance.

[0042] After the conveying is completed, the cleaning door 217 is opened to clean the impurities and broken particles in the collecting chamber 214 .

[0043] It is worth noting that the start and stop of the moving wheel 11 and the application of the feeding mechanism are prior arts and will not be described in detail here.

[0044] The above is the overall working process of the utility model, and you can repeat this step next time you use it.
