Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of transfer and storage devices, specifically a pseudo-boehmite transfer and storage device. Background Technology
[0002] Boehmite can be used as a binder for semi-synthetic rare earth Y-type molecular sieve cracking catalysts, a binder for aluminosilicate refractory fibers, a catalyst for alcohol dehydration to ethylene production, and a catalyst for ethylene oxide production. It can also be used as a raw material for the production of catalyst supports, activated alumina, and other aluminum salts.
[0003] Boehmite is a white colloidal substance (wet product) or powder (dry product). Powdered boehmite is mostly transported using ton bags, also known as bulk bags, flexible containers, or ton bags. These are flexible transport packaging containers with advantages such as moisture-proof, dust-proof, radiation-proof, and robust safety. However, most current ton bags have a simple bag structure, and there are three ways to remove the material from them: The first method is to manually remove the material from the inlet, which is inefficient, labor-intensive, and time-consuming. The second method is to use a crane to lift the ton bag and then tilt it, allowing the material to enter the equipment from the inlet. This method results in significant material waste and is also complex. The third method is to cut a slit at the bottom of the ton bag as an outlet, from which the material is poured into the equipment. This method makes the ton bag unrecyclable and requires all the material to be emptied, preventing batch unloading and hindering the use of boehmite. Therefore, this paper proposes a boehmite transfer and storage device. Utility Model Content
[0004] The purpose of this utility model is to provide a pseudo-boehmite transfer and storage device in order to solve the problems mentioned above.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a pseudo-boehmite transfer and storage device, comprising a ton bag consisting of an outer bag, an inner bag, and a feed inlet, wherein the inner bag is distributed inside the outer bag and the top edge of the feed inlet is sewn and fixed to the inner side of the outer bag near the top, and the feed inlet is sewn and fixed to the top center of the inner bag and communicates with the inner cavity of the inner bag;
[0006] The bottom of the outer bag and the inner bag are provided with unloading components, which are used to unload the material inside the inner bag.
[0007] The unloading assembly includes an inner discharge port, a connecting tube bag, a bottom sealing plate, a side discharge port, an outer discharge port, and an unloading tube bag;
[0008] The inner discharge port is located at the bottom of the inner bag. The connecting tube bag is sewn and fixed to the bottom of the inner bag and aligned with the inner discharge port. The bottom sealing piece is sewn and fixed to the bottom of the inner discharge port. The side discharge port is located on the outside of the connecting tube bag near the bottom. The channel formed by the inner discharge port, the connecting tube bag, and the side discharge port is used to allow the material inside the inner bag to enter the inside of the outer bag.
[0009] The outer discharge port is located at the bottom of the outer bag, and the unloading tube is sewn and fixed to the bottom of the outer bag and aligned with the outer discharge port. The channel formed by the outer discharge port and the unloading tube is used to unload the material inside the outer bag.
[0010] As a further embodiment of this utility model: the outer wall diameter of the bottom sealing plate is greater than the inner wall diameter of the outer discharge port, the height of the inner bag is less than the height of the outer bag, and the height difference between the outer bag and the inner bag is greater than the height of the connecting tube bag.
[0011] As a further improvement of this utility model, the inner feed port has a number of centrally distributed central leakage holes arranged in a matrix.
[0012] As a further improvement of this utility model: the two sides of the outer bag are symmetrically sewn and fixed with transfer straps, and the top of the inner bag is symmetrically sewn and fixed with unloading straps.
[0013] As a further improvement of this utility model: the widths of the two unloading slings decrease sequentially and are interlocked with each other, and the movable parts of the unloading slings are fixed to the upper surface of the inner bag by Velcro.
[0014] The end of the unloading tube bag away from the outer discharge port extends to the top of the outer side of the outer bag and is bent 180 degrees to be fixed to the side of the outer bag with Velcro. All other parts of the unloading tube bag that come into contact with the outer bag are fixed with Velcro.
[0015] As a further improvement of this utility model: a shielding tube bag is also sewn and fixed between the bottom of the inner bag and the bottom of the inner wall of the outer bag, and the shielding tube bag is distributed on the outside of the connecting tube bag.
[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] By setting up outer and inner bags, as well as unloading components, transfer slings, and unloading slings, the inner and outer bags are kept in a tight fit by the weight of the material during daily transfer and hoisting, thus ensuring a good leak-proof condition. When unloading is required, the material can be lifted by the unloading slings to open the unloading channel. The overall operation is simple, convenient, and reusable. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figures 1-5 In this embodiment of the utility model, a pseudo-boehmite transfer and storage device includes a ton bag consisting of an outer bag 1, an inner bag 2, and a feed inlet 3. The inner bag 2 is distributed inside the outer bag 1, and the top edge of the feed inlet 3 is sewn and fixed to the inner side of the outer bag 1 near the top. The feed inlet 3 is sewn and fixed to the top middle of the inner bag 2 and communicates with the inner cavity of the inner bag 2.
[0026] The bottom of the outer bag 1 and the inner bag 2 are provided with unloading components 6, which are used to unload the material inside the inner bag 2.
[0027] The unloading assembly 6 includes an inner discharge port 601, a connecting tube bag 602, a bottom sealing plate 603, a side discharge port 604, an outer discharge port 606, and an unloading tube bag 607;
[0028] The inner discharge port 601 is located at the bottom of the inner bag 2. The connecting tube bag 602 is sewn and fixed to the bottom of the inner bag 2 and aligned with the inner discharge port 601. The bottom sealing plate 603 is sewn and fixed to the bottom of the inner discharge port 601. The side discharge port 604 is located on the outside of the connecting tube bag 602 near the bottom. The channel formed by the inner discharge port 601, the connecting tube bag 602, and the side discharge port 604 is used to allow the material inside the inner bag 2 to enter the inner side of the outer bag 1.
[0029] The outer discharge port 606 is located at the bottom of the outer bag 1. The unloading tube 607 is sewn and fixed to the bottom of the outer bag 1 and aligned with the outer discharge port 606. The channel formed by the outer discharge port 606 and the unloading tube 607 is used to unload the material inside the outer bag 1.
[0030] The outer diameter of the bottom sealing plate 603 is larger than the inner diameter of the outer discharge port 606, the height of the inner bag 2 is smaller than the height of the outer bag 1, and the height difference between the outer bag 1 and the inner bag 2 is greater than the height of the connecting tube bag 602.
[0031] The outer bag 1 is symmetrically sewn and fixed with transfer straps 4 on both sides, and the inner bag 2 is symmetrically sewn and fixed with unloading straps 5 on the top.
[0032] In this embodiment, the operation steps for transferring and storing boehmite using this ton bag are as follows:
[0033] During loading, the ton bag is connected to the hook on the packaging equipment via the transfer sling 4 to achieve vertical unfolding (this is the conventional structure for loading ton bags, so it will not be elaborated further). Then, the inlet 3 is connected to the outlet of the packaging equipment to carry out the loading operation. At this time, the pseudo-boehmite material falls into the inner bag 2. Under the gravity of the pseudo-boehmite material, the inner bag 2 moves down and fits against the bottom of the inner wall of the outer bag 1. At this time, the connecting tube bag 602 is in a folded and contracted state, the side drop outlet 604 is blocked by the folded connecting tube bag 602, and the bottom sealing piece 603 forms a block at the outer drop outlet 606, so that the pseudo-boehmite material can be stably stored inside the inner bag 2.
[0034] During the subsequent hoisting and transfer process, the hoisting operation is also carried out by the transfer sling 4. Similarly, during this process, the boehmite material is stably stored inside the inner bag 2, and there will be no leakage.
[0035] When unloading is required, the unloading sling 5 can be lifted directly by the hoisting equipment. At this time, the hoisting force is directly applied to the inner bag 2, causing the inner bag 2 to move upward relative to the outer bag 1. At this time, the connecting tube bag 602 unfolds and the bottom sealing plate 603 moves upward to release the blockage of the external discharge port 606. At this time, the side discharge port 604 is opened, and the pseudo-boehmite material in the inner bag 2 falls into the outer bag 1 through the connecting tube bag 602 and the side discharge port 604. Then, the unloading tube bag 607 is unfolded and connected to the receiving device. The boehmite material inside the outer bag 1 is unloaded through the unloading tube bag 607. During this process, the unloading tube bag 607 can be squeezed and cut off near the external discharge port 606 by external tools to stop unloading. Then, the cut off of the unloading tube bag 607 can be released to carry out secondary unloading, thereby realizing the staged unloading operation.
[0036] Please refer to this carefully. Figures 1-5 The inner feed port 601 has several centrally distributed central leakage holes 605 arranged in a matrix. A shielding tube bag 608 is also sewn and fixed between the bottom of the inner bag 2 and the bottom of the inner wall of the outer bag 1. The shielding tube bags 608 are distributed on the outside of the connecting tube bag 602.
[0037] In this embodiment: the central hole 605 can prevent residue from falling out and is used for the final small amount of material to be unloaded. During daily loading and transportation, the small amount of material falling into the outer discharge port 606 through the central hole 605 will not cause excessive compression to the unloading tube bag 607, thus ensuring stable use in daily transportation.
[0038] The shielding tube bag 608 is used to limit the material falling from the side discharge port 604 and prevent it from spreading to other locations.
[0039] Please refer to this carefully. Figures 1-4 The widths of the two unloading slings 5 decrease sequentially and are interlocked with each other. The movable parts of the unloading slings 5 are fixed to the upper surface of the inner bag 2 by Velcro.
[0040] The end of the unloading tube bag 607 away from the outer discharge port 606 extends to the top of the outer side of the outer bag 1 and is bent 180 degrees to be fixed to the side of the outer bag 1 by Velcro. Other parts of the unloading tube bag 607 that come into contact with the outer bag 1 are also fixed by Velcro.
[0041] In this embodiment: by folding and pasting the unloading tube bag 607, the sealing operation of the external discharge port 606 can be achieved. During the hoisting and transportation process, the unloading tube bag 607 is flattened under the squeezing force of the material on the external discharge port 606. Combined with the 180-degree bending structure at its end, a good sealing state can be achieved.
[0042] The unloading sling 5 is fixed by Velcro to avoid misuse during hoisting. It is only deployed and used when unloading, thus ensuring the order of use of the unloading sling 5 and the transfer sling 4. (It should be noted that the structure of Velcro is a conventional technology and is widely used, so it will not be described in detail.)
[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
