Description

Technical Field

[0001] The invention relates to the technical field of mechanical devices for dumping and emptying materials, in particular to a ton bag turning machine. Background Art

[0002] The aluminum electrolysis industry mainly uses the Hall-Héroult cryolite-alumina molten salt electrolysis method, which is a multiphase electrolyte system with fluoride salts mainly based on cryolite as solvent and alumina as solute. With the rapid development of aluminum electrolysis technology and the increasing size of electrolytic cells, the demand for alumina raw materials used for aluminum electrolysis is also increasing. The alumina raw materials used in aluminum electrolysis industry are usually packaged in packaging bags (commonly known as ton bags). When in use, the unloading personnel manually cut the alumina packaging bags with a blade, so that the alumina in the packaging bags can be poured out and enter the feeding port. This pouring method is not only inefficient, labor-intensive, time-consuming and labor-intensive, but also the alumina packaging bags will be destroyed and cannot be used again, thus causing a great waste of resources.

[0003] The prior art also attempts to solve the above problems through various types of dumping machines, such as CN201914725U bag turning machine, CN210417025U a flipping dumping device, etc., which can empty and pour the materials from their packaging bags to a certain extent. However, in the actual production environment, the general process is to lift a ton bag and unload a ton bag, so the lifting device needs to work back and forth many times; to improve work efficiency, the lifting device can suspend multiple ton bags at a time, but the conventional dumping machine can only dump one ton bag at a time. At this time, the lifting device needs to wait for the previous bag to be unloaded before placing the second bag on the dumping machine for dumping. Therefore, the above conventional dumping device still has technical problems such as low work efficiency. Summary of the invention

[0035] [Example 1] Basic structure

[0036] like Figure 1-4As shown, a ton bag turning machine described in this embodiment includes a frame, a driving device, and a flap. The frame is used to support, assemble, and carry the flap and / or the driving device. The driving device is used to drive the flap to rotate, and the flap is used to support, carry, and turn over the materials. The frame is a frame and / or box-type structure, and a rotating shaft is provided on one side of the top of the frame. The flap and the frame are hinged through the rotating shaft, and the driving device is provided at the bottom of the flap. The bag turning machine is used to turn over the packaging bags of alumina raw materials (commonly known as ton bags) in the production of aluminum electrolysis industry. The weight of the ton bags is generally more than 1 ton, and may also be more than half a ton, but they are all material packaging bags that cannot be directly operated by manpower; on the other hand, powdery, granular and other materials similar to alumina raw materials can be turned over by the bag turning machine described in this embodiment. Based on the above-mentioned uses, the model, specification, material, etc. of the materials used to manufacture the above-mentioned bag turning machine should match the above-mentioned use requirements, so as to meet the normal operation of the bag turning machine. The specific details will not be repeated. In addition, it needs to be further explained that the frame and flap of the above-mentioned bag turning machine are not limited to the plane and rectangle shown in the accompanying drawings. The frame can be flexibly adjusted according to the actual needs of bag turning (involving factors such as the type of driving device, the turning action of the flap, the tipping action of the ton bag, and the operation place of the equipment), such as the special shape of the local arc edge; in particular, the structure of the flap, the component is named "plate" here, but in combination with the actual application, it should be understood that the supporting components that can carry heavy materials belong to the category of the flap described in this embodiment, such as grid-shaped pads, screen plates, railings, etc., or special-shaped plates spliced ​​or integrally formed at a certain inclination angle, etc., and its meaning cannot be simply limited literally.

[0037] The driving device of the bag turning machine can adopt mechanical transmission methods such as crank connecting rod, gear, rack, steel cable, etc., and can also adopt fluid transmission methods such as hydraulic, hydraulic, pneumatic, etc., and can also adopt electric transmission methods such as motor, electromagnetic, etc., among which hydraulic transmission is more common.

[0038] [Example 2] Adding a sub-plate

[0039] like Figure 1-4 As shown, on the basis of the above-mentioned embodiment, the bag turning machine described in this embodiment is provided with a sub-plate, which is used to support, carry and turn over materials, and the sub-plate is assembled on the frame. Conventional bag turning machines can only turn over one ton bag at a time, while a crane can hang multiple ton bags at a time. When the first ton bag is placed on the bag turning machine and turned over, the other ton bags have nowhere to be placed and can only be suspended by the crane and wait. The other ton bags can only be operated after the first ton bag is turned over, resulting in low work efficiency. In order to solve the above-mentioned problems, this embodiment provides a sub-plate outside the flap, and at least one sub-plate is provided, and the bearing capacity of the sub-plate is equivalent to that of the flap. The sub-plate is set at a position adjacent to the flap. When the crane transfers multiple ton bags, the multiple ton bags can be placed on the flap and the sub-plate at the same time, and the crane returns empty.

[0040] The sub-plate is provided with a track device that moves to the flap position and enables the sub-plate to replace the flap, or the sub-plate and the flap overlap. The sub-plate replacing the flap means that the flap is withdrawn from the original working position, and the sub-plate occupies the working position of the original flap, that is, the flap is withdrawn after the ton bag on it is overturned, and the sub-plate carries the second ton bag and transfers it to the working position (i.e. the material discharge port), and the sub-plate performs a flipping movement to overturn the second ton bag; at this time, the sub-plate is required to have the same rotating shaft and / or driving device as the flap, because the flap has been withdrawn from the original working position, the rotating shaft assembled on the flap is also transferred together, therefore, the sub-plate needs to be provided with a dedicated rotating shaft, that is, the sub-plate is movably connected to the frame by the dedicated rotating shaft. The driving device for driving the flap or sub-panel can be configured independently, that is, the flap and sub-panel use independently configured driving devices to work respectively, or the driving device can be configured uniformly, that is, the flap and sub-panel share the same set of driving devices. In this case, it is necessary to set a snap device between the driving device and the flap or sub-panel, and the snap device can realize assembly and detachment with different flaps or sub-panels.

[0041] The overlapping of the auxiliary plate and the flap means that after the flap has tipped over the ton bag, the auxiliary plate carrying the new ton bag is translated onto the flap, and the two overlap up and down. When the auxiliary plate needs to tip over the material, the driving device is started to flip the flap, and the flap can drive the auxiliary plate on it to flip together, so that the new ton bag on the auxiliary plate can complete the dumping action. Furthermore, when the auxiliary plate flips with the flap, the auxiliary plate cannot be separated from the overlapping relationship with the flap. Therefore, the track device between the auxiliary plate and the flap only allows the auxiliary plate to translate from outside the flap to above the flap (or return in the opposite direction), thereby limiting other displacements of the auxiliary plate when flipping with the flap.

[0042] The above lists two ways to achieve alternating tipping between the auxiliary plate and the flap. Other structural methods that can achieve the same function based on this design concept should also fall within the meaning expressed in this application and will not be described in detail here.

[0043] Regarding the track device between the sub-plate and the flip plate, combined with the above-mentioned flipping working mode, it can be a translation track, a turntable track, or a special track matching the corresponding flipping working mode. The specific details are elaborated in detail in the following embodiments.

[0044] [Example 3] Parallel sub-plates

[0045] like Figure 3 , 4 As shown, based on the above embodiment, the auxiliary plate and the flap described in this embodiment are respectively located on two different horizontal planes, the auxiliary plate and the flap are arranged in parallel.

[0046] The auxiliary plate is provided with a translation track, which extends to the flap. The auxiliary plate can translate and slide along the translation track in the direction of the flap, and slide until the auxiliary plate overlaps with the flap.

[0047] The translation track is arranged at the bottom of the auxiliary plate and the flap plate, and the translation track is provided with at least two guide rails, and the guide rails are arranged in parallel; the translation track is divided into an auxiliary plate rail and a flap plate rail, the auxiliary plate rail is fixed on the frame, the flap plate rail is fixed at the bottom of the flap plate, and the flap plate is provided with a guide groove corresponding to the flap plate rail; the auxiliary plate rail and the flap plate rail are aligned along the translation direction of the guide rail, and a gap is left at the connection between the two to disconnect them from each other; the auxiliary plate is provided with a guide wheel matching the translation track.

[0048] To facilitate understanding of the above structure and its connection relationship, the following takes a structure in which a flap and a sub-plate are arranged in parallel as an example to illustrate the structural characteristics, connection relationship, and usage method of the bag turning machine.

[0049] Initially, the auxiliary plate is separated from the flap, and the auxiliary plate is located on the auxiliary plate track. When in use, two ton bags are placed on the flap and auxiliary plate at one time, and the crane returns; first start the drive device under the flap, lift the flap and flip it to dump the ton bag on it to unload the material; then the flap returns to its original position, and the flap track is aligned with the auxiliary plate track. In the second stage, prepare to flip the ton bag on the auxiliary plate; first, the auxiliary plate slides along the auxiliary plate track toward the flap track (which can be driven by a motor or hydraulic system), the guide wheel enters the flap track from the auxiliary plate track, and the bracket of the guide wheel passes through the guide groove, the auxiliary plate translates on the flap, and when the auxiliary plate overlaps with the flap, all the guide wheels enter the flap track; then start the drive device under the flap again, and when the flap flips, it drives the auxiliary plate and the ton bag on the auxiliary plate to flip together, completing the dumping of the second ton bag. It should be noted that when the secondary plate is flipped in the second stage, the secondary plate rail is separated from the flap rail, and the guide wheel at the bottom of the secondary plate is confined in the flap rail, so that the secondary plate will not undergo radial displacement of the rotation axis when flipped. Furthermore, when the secondary plate overlaps the flap, a locking device can be provided between the secondary plate and the flap to lock the secondary plate on the flap to prevent the guide wheel on the secondary plate from sliding out of the flap rail.

[0050] The flap and the auxiliary plate are both grid structures.

[0051] Furthermore, guardrails can be set around the auxiliary plate and the flap to prevent the ton bag from tilting and sliding. Because the auxiliary plate and the flap need to be translated and overlapped, the guardrails on the auxiliary plate and the flap need to meet the overlapping action of the two plates, and after the auxiliary plate is translated onto the flap, it needs to be flipped over together with the flap to make the flip bag tilt and discharge. Therefore, no guardrail is set in the middle position where the flap and the auxiliary plate are spliced, and no guardrail is set on one side of the rotating shaft. The setting method of guardrails in other positions is relatively conventional and will not be repeated.

[0052] [Example 4] Rotating plate type flap

[0053] like Figure 5 , 6 As shown, based on the above embodiment, the track device described in this embodiment is a turntable track.

[0054] The turntable track includes a circular rail and a turntable frame. The circular rail is provided with a circular guide rail. There are at least two circular guide rails, and all the circular guide rails are arranged concentrically. The circular rail is fixed on the frame. The turntable frame is arranged on the circular rail, and the turntable frame is provided with a slider and / or a pulley matching the circular rail. The turntable frame can rotate along the circular rail through the slider and / or the pulley.

[0055] The flap and sub-plate are fixed on the turntable frame; there are 2-4 flaps and sub-plates in total, and the flaps and sub-plates are arranged in a grid shape; the flap corresponds to the position of the material drop port, and the others are sub-plates; when the flap has finished flipping over the ton bag and rotated out of the material drop port, the flap is transformed into a sub-plate, and at the same time, the sub-plate that has rotated into the material drop port is transformed into a flap. It can also be understood that all the sub-plates installed on the turntable frame are sub-plates, and the function of these sub-plates is to carry the surplus ton bags lifted by the crane, and only the sub-plates rotated to the material drop port are called flaps, that is, in this position, the ton bag is flipped over by the flap to empty the material, and the material can only be flipped over at the material drop port; after the flap has flipped over the ton bag, it immediately rotates out of the material drop port, and then receives a new ton bag, and then it is transformed into a sub-plate.

[0056] Preferably, it is best to have a total of 4 flaps and sub-panels. According to the above-mentioned crane lifting two ton bags each time, this embodiment can undertake the carrying capacity of two cranes, and the work efficiency is further improved. Under actual working conditions, each production line will generally be equipped with 3-8 bag turning machines for feeding. The number of bag turning machines is large, and the crane needs to frequently go back and forth to lift the ton bags, and the construction cost and operation cost are high. In this embodiment, one bag turning machine can be equivalent to 2-4 conventional ones, or even more, and the overall work efficiency is also greatly improved.

[0057] [Example 5] Extended lying board

[0058] like Figure 3 , 6 As shown, based on the above embodiments, the flap and / or sub-panel described in this embodiment is provided with a lying plate, which extends from the flap rotation axis toward a direction away from the flap, or extends from the sub-panel rotation axis toward a direction away from the sub-panel.

[0059] The lying plate and the flip plate, or the lying plate and the auxiliary plate, are located in the same plane or at an angle of a certain threshold.

[0060] The lying plate is an extension of the flap or sub-plate toward the material outlet. Generally, the installation position of the bag turning machine is relatively high, and the space on the platform is narrow. Equipment installation and operation, personnel activities, temporary storage of packaging bags, etc. need to be arranged in this space. Therefore, the size of the bag turning machine should be minimized as much as possible, that is, the flap or sub-plate can only accommodate ton bags, and the space around the ton bags is extremely limited; when the bag turning machine flips and dumps materials, the ton bags tilt toward the material outlet, and it is easy to slide off the flap, causing damage to the equipment such as the material outlet, affecting the material discharge and production continuity, and the subsequent recovery work is also time-consuming and laborious. In this embodiment, based on the above embodiment, the flap and sub-plate are extended toward the material outlet for a section to receive the tilted and fallen ton bags to prevent them from sliding off the bag turning machine. Furthermore, the lying plate can also be designed as a grid, a horizontal bar, a mesh, a screen and other structures, which on the one hand prevent the ton bags from sliding down along the flap, and on the other hand can also control the constant discharge of materials to a certain extent.

[0061] Furthermore, guardrails similar to those in Example 3 may be provided on both sides of the lying board.

[0062] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to examples, those skilled in the art should understand that the technical solutions of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should be included in the scope of the claims of the present invention.
