Double-bag overturning device

Abstract

The invention discloses a double-bag overturning device which comprises a support. The double-bag overturning device further comprises a material overturning hopper composed of two frames, the inner sides of the two frames are connected together, the two sides of the material overturning hopper are supported on the support through rotating shafts and bearings, and the rotating shaft on one side extends out to be connected with a gear motor through a coupler; each frame is formed by connecting an octagonal upper opening edge, an octagonal lower opening edge and a sliding way between the octagonal upper opening edge and the octagonal lower opening edge, and self-locking doors are arranged on the outer sides of an upper opening and a lower opening respectively; a sliding chassis capable of vertically sliding through the sliding way is arranged in each frame. The double-bag overturning device has the advantages that material hitting automation is achieved; the labor strength of a worker is reduced, and the operation environment of the worker is improved; the using efficiency of a crown block is improved; two bags can be overturned at the same time, continuous bag overturning is achieved, and the labor efficiency of an operator is improved in a multiplied mode; the good conditions of the bags can be kept after bag overturning, and the bags can be recycled and repeatedly used; the sliding chassis is used, and discharging space is saved; meanwhile, manufacturing materials are greatly saved, and the manufacturing cost is reduced.

Description

1. Technical field [0001] The invention belongs to the technical field of unloading tools, and in particular relates to a double bag turning device. 2. Background technology [0002] At present, the raw materials used in electrolytic production in the electrolytic aluminum industry are purchased alumina powder in bags, with a diameter of 1.2 meters and a height of 1.3 meters, and each bag contains about 1.5 tons of alumina powder. In order to take out the alumina powder from the bag, the current unloading method is: use a crane to lift the bag to the silo, and then manually cut the bottom of the bag to make the alumina powder in the bag leak into the silo, etc. After one bag was leaked, another bag was hung. This method has the following disadvantages: 1. It takes a long time to occupy the crane and ground personnel, and the efficiency is low. 2. It can only feed one bag at a time, which is slow and labor-intensive. 3. The operator stands on the top of the silo for a long...
