At present, alumina packaging and transportation are all packaged in large bags, which are divided into three packaging specifications of 1.7 tons, 1.5 tons and 1.3 tons. The large bag loading method is: the overhead crane lifts the bag to the loading port of the material station once, and cuts the bottom of the large bag with a blade to damage the large bag, causing the alumina to spill into the loading port; this operation causes the alumina packaging bag to be scrapped after only one use and cannot be reused, increasing production costs; at the same time, the material unloading speed after the alumina packaging bag is cut is too fast, and the alumina powder suddenly falls into the loading port, causing too much dust, which causes the working area environment Pollution; Application No. CN201610219641.5 discloses a knife-free automatic unloading container bag, which is designed with a discharge port at the bottom of the bag, and the discharge port can be opened when unloading is required; however, designing a discharge port at the bottom of the bag will seriously affect the structural strength of the container bag. This container bag can be used when loading small-mass materials, but when loading large-mass materials, this container bag will have the risk of rupture and material spillage. Therefore, the container bag of this structure is not suitable for the loading operation of alumina powder. It is necessary to study an alumina powder loading device to solve the above problems. Summary of the invention

[0003] The utility model aims to solve the above problems and provide a large-bag turning device of alumina with simple structure and cost saving.

[0004] In order to achieve the above purpose, the technical solution of the utility model is:

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work, any modifications, equivalent replacements, improvements, etc., should be included in the protection scope of the utility model.

[0020] like Figures 1 to 4 As shown, this embodiment discloses an alumina large bag turning device, including a support frame, on which a housing 1 for loading an alumina packaging bag 14 is arranged, and a transmission mechanism is arranged on the outer side of the middle of the housing 1 and is rotatably connected to the support frame through the transmission mechanism;

[0021] The housing 1 is in the shape of a cylindrical shell with an open top, and a protective frame is arranged on one side of the top of the housing 1; the protective frame is located on the side of the rotation direction of the housing 1, and the protective frame includes four columns 2, which are arranged at equal intervals along the arc direction of the top end wall of the housing 1, and the bending arc length between two columns 2 located on both sides of the edge is not greater than half of the circumference of the top end wall of the housing 1; the axial direction of the column 2 is consistent with the axial direction of the housing 1, the bottom end of the column 2 is fixedly connected to the top of the housing 1, and the adjacent columns 2, a first limiting rod 3 and a second limiting rod 4 are arranged between the columns 2, there are several first limiting rods 3 and the several first limiting rods 3 are arranged at equal intervals along the axial direction of the column 2, the two end heads of the first limiting rod 3 are respectively fixedly connected to the side walls of the two adjacent columns 2, and the middle part of the first limiting rod 3 is bent toward the axis of the accommodating shell 1; the second limiting rod 4 is an upwardly bent arc structure, the two end heads of the second limiting rod 4 are respectively fixedly connected to the top ends of the two adjacent columns 2, and the middle part of the second limiting rod 4 is inclined toward the axis of the accommodating shell 1.

[0022] When the transmission mechanism drives the containing shell to flip, the alumina powder in the alumina packaging bag will slowly flow out from the port position of the alumina packaging bag. As the flipping angle increases, the alumina powder in the alumina packaging bag gradually decreases. When the alumina packaging bag is flipped to 180 degrees, the residual alumina powder will flow out of the alumina packaging bag, thereby realizing the loading operation of the alumina powder. Of course, when flipping to 180 degrees, it is possible that the alumina packaging bag and some residual alumina powder will fall out of the containing shell together. At this time, you only need to manually take out the alumina packaging bag and shake off the residual alumina powder.

[0023] The support frame includes a base 5, a first mounting seat 6, and a second mounting seat 7. The base 5 is a hollow frame structure. The base 5 is fixed to the upper end of the feeding port of the electrolytic aluminum production equipment. The first mounting seat 6 and the second mounting seat 7 are fixedly connected to the base 5. The first mounting seat 6 and the second mounting seat 7 are symmetrically arranged on both sides of the accommodating shell 1. A transmission mechanism is connected between the first mounting seat 6, the second mounting seat 7 and the outer side wall of the accommodating shell 1.

[0024] The transmission mechanism includes a power assembly, a first rotating shaft 8, and a second rotating shaft 9. The axis of the first rotating shaft 8 coincides with the axis of the second rotating shaft 9, and the protective frame is located on one side above the axis of the first rotating shaft 8; one side wall of the accommodating shell 1 is rotatably connected to the first mounting seat 6 through the first rotating shaft 8, and the other side of the accommodating shell 1 is fixedly connected to one end of the second rotating shaft 9, and the other end of the second rotating shaft 9 passes through the second mounting seat 7 and is connected to the power assembly, and the outer side wall in the middle part of the second rotating shaft 9 is rotatably connected to the second mounting seat 7.

[0025] The power assembly includes a motor 13, a reducer 10, a driving gear 11, and a driven gear 12; the motor 13 and the reducer 10 are fixedly connected to the top of the second mounting seat 7, the motor 13 is transmission-connected to the reducer 10, the output shaft of the reducer 10 is connected to the driving gear 11, the driven gear 12 is fixedly sleeved on the outside of one end of the second rotating shaft 9 passing through the second mounting seat 7, and the driven gear 12 is meshingly connected to the driving gear 11.

[0026] The motor drives the reducer to work, so that the driving gear drives the driven gear and the second rotating shaft to rotate. The rotation of the second rotating shaft can drive the containing shell to flip, thereby realizing the flipping and unloading operation of the alumina packaging bag.

[0027] When the utility model performs the alumina powder feeding operation, the alumina packaging bag loaded with the alumina powder is firstly lifted and placed into the containing shell by using the overhead crane, and then the transmission mechanism is controlled to flip the containing shell, so that the containing shell is flipped toward the side where the protective frame is provided. At this time, the alumina packaging bag abuts against the inner wall of the containing shell close to the protective frame under the action of gravity, and the first limiting rod squeezes the side wall of the alumina packaging bag and sinks into the inner side of the alumina packaging bag, so that it is not easy to slide out of the containing shell; when the flipping angle of the containing shell is greater than 90 degrees, the second limiting rod can block the port position of the alumina packaging bag, further preventing the alumina packaging bag from falling out of the containing shell (such as Figure 4As shown); with the slow flipping of the containing shell, the alumina powder in the alumina packaging bag will flow out from the opening at the top of the alumina packaging bag and flow into the loading port below the support frame through the hollow structure on the protective frame body, thereby realizing the loading operation of the alumina powder; it does not need to cut the alumina packaging bag, which not only avoids the one-time use of the alumina packaging bag, but also reduces dust by slowly dumping the material, saving production costs while avoiding pollution to the production environment; and, it does not have the risk of rupture of the alumina packaging bag, and can effectively realize the loading operation of large-mass alumina powder, which brings convenience to the production operation of electrolytic aluminum.
