Description

Technical Field

[0001] This utility model belongs to the field of overhead crane unloading technology, specifically relating to a dust prevention device for electrolytic overhead crane unloading. Background Technology

[0002] Chinese patent application number 202211616234.X discloses a multi-functional overhead crane feeding device for electrolytic aluminum. The device uses a first motor to rotate an inclined column on a rotating shaft. As the inclined column rotates, it continuously pushes a stop column in the chute to the left. At the same time, a first spring installed on the outside of the feed box continuously pushes the stop column to the right. This causes the impact block at the bottom of the stop column to continuously impact the blocky additives entering the chute. Meanwhile, the entire electric push rod moves the inclined column up and down on the rotating shaft surface to adjust the impact force between the impact block and the wear-resistant coating plate. This prevents a large amount of blocky additives from clogging the feeding pipe and also facilitates better mixing of the additives with the electrolyte.

[0003] However, when the existing electrolysis overhead cranes are unloading materials, a large amount of dust is generated when the materials fall into the feeding trough. The dust spreads rapidly, making it impossible for workers to get close for a short period of time. Moreover, the large amount of dust obstructs the view, making it impossible for workers to observe the situation inside the feeding trough, resulting in a harsh working environment and poor practicality.

[0030] As a preferred option, two sets of anti-fall mechanisms 9 are symmetrically installed on the top of the connecting shell 71 to prevent the feeding device 1 from falling.

[0031] The multi-stage telescopic cylinder, lifting mechanism, fall protection mechanism, gearbox, drive motor, and bellows in this case are existing technologies. The drive motor and bellows are the same structures and connection methods as those in the cited documents. The lifting mechanism is an SEW-driven lifting mechanism. The fall protection mechanism consists of a steel wire rope, mounting frame, and springs. As long as the multi-stage telescopic cylinder, lifting mechanism, fall protection mechanism, gearbox, drive motor, and bellows meet the requirements of this case, they are all acceptable.

[0032] Working principle: All electrical components mentioned in this application are connected to an external power supply and control switch during use. After the utility model is installed, first check the installation, fixation, and safety protection of the utility model, and then it can be used. During use, the lifting mechanism 6 drives the dust cover 3 to descend to the material trough, keeping it as close as possible to the bottom of the trough to reduce the range of dust raised during material discharge. During the descent of the dust cover 3 by the lifting mechanism 6, the multi-stage telescopic cylinder 2 extends and descends. When material is being discharged, the material is discharged from the material shell 5 through the lifting mechanism 6 and the discharge component 8. At the same time, the external dust collector is activated. The dust collector sucks the generated dust from the suction shell 4 through the multi-stage telescopic cylinder 2. By symmetrically setting two sets of multi-stage telescopic cylinders 2, the dust collection efficiency is improved.

[0033] When it is necessary to replace the multi-stage telescopic cylinder 2 and dust cover 3, start the drive motor 73, which drives the rotating shaft 74 to rotate through the gearbox 72. The rotating shaft 74 drives the gear 75 to rotate, and the gear 75 meshes with the gear ring 76, which drives the connecting cylinder 77 to rotate. The connecting cylinder 77 drives the discharge component 8 to rotate through the connecting ring 78 and the first flange 79. Rotate the collar 10 and the mounting ring 11 to a suitable angle to facilitate the disassembly of the first bolt 113 and the second bolt 115, so that the multi-stage telescopic cylinder 2 is disengaged from the bottom cylinder 83. Then, by rotating the dust suction shell 4 and the discharge shell 5, the dust suction shell 4 is removed from the multi-stage telescopic cylinder 2, and the discharge shell 5 is removed from the bottom cylinder 83. After removing the dust suction shell 4 and the discharge shell 5, the dust cover 3 can be removed from the multi-stage telescopic cylinder 2 and the bottom cylinder 83 respectively. In this way, the multi-stage telescopic cylinder 2 and the dust cover 3 can be replaced and maintained.
