Abstract

This utility model discloses a device for recovering and removing impurities from indium metal oxide, including a support leg. A top ring is fixedly installed on the top of the support leg, and a tank is fixedly installed on the inner side of the top ring. A rotating mechanism is fixedly installed on one side of the tank. Using this structure, the indium metal oxide raw material to be processed enters from the top of the tank and contacts the upper filtration and impurity removal mechanism. A second motor drives the stirring frame to rotate at high speed, and a conical stirring auger fully agitates the raw material, dispersing it evenly and ensuring it makes full contact with the filter screen.

Description

Technical Field

[0001] This utility model belongs to the field of indium oxide recovery and impurity removal technology, and specifically relates to an indium oxide recovery and impurity removal device. Background Technology

[0002] Against the backdrop of the booming development of high-tech industries such as semiconductors, flat panel displays, and photovoltaics, indium oxide is an important raw material for the preparation of key materials such as ITO (indium tin oxide) targets and transparent conductive films. Its recycling and reuse technology is becoming increasingly important. Indium oxide recycling and impurity removal equipment is a key piece of equipment to ensure the purity and quality of recycled products, which directly affects the utilization efficiency and economic benefits of renewable resources. Currently, indium oxide recovery and impurity removal filtration devices used in the industrial sector generally suffer from technical bottlenecks. Their structural designs are relatively simple, often employing traditional static filter screen filtration modes. When processing indium oxide powder with high concentrations or containing complex impurities, the filtration efficiency is insufficient to meet the demands of large-scale production. Due to the lack of an effective impurity guidance and dispersion mechanism, impurities easily accumulate rapidly on the top of the filter screen, forming a blockage layer, significantly reducing the filtration throughput, and even causing filtration interruptions. A more prominent problem is the serious deficiencies in cleaning and maintenance of existing devices. When the filter screen becomes clogged, operators must stop the machine to disassemble and clean it. During this period, the equipment cannot operate continuously, which not only significantly reduces production continuity but also increases labor costs and equipment maintenance frequency. These technical limitations result in low indium oxide recovery efficiency and increased production costs. It is evident that the existing technology has certain defects and shortcomings in its overall application, thus requiring improved design. Utility Model Content

[0007] Furthermore, the filter screen is generally conical in shape, and an internal discharge valve is fixedly installed at the bottom output end of the filter screen. The filter screen is made of stainless steel.

[0008] Furthermore, the stirring rack includes a rotating shaft, which is fixedly installed at the bottom output end of the second motor. The upper surface of the rotating shaft is fixedly equipped with scraping side frames arranged in a ring at equal intervals. The outer side of the scraping side frame is in close contact with the inner wall of the filter screen.

[0009] Furthermore, a stirring auger is fixedly installed at the lower end of the outer surface of the rotating shaft. The stirring auger is generally conical in shape, and the outer side of the stirring auger is in close contact with the inner wall of the filter screen.

[0010] Furthermore, a support bottom ring is fixedly installed at the bottom of the support leg, and an anti-slip washer is fixedly connected to the support bottom ring. The bottom of the anti-slip washer is provided with anti-slip texture.

[0011] In summary, the present invention has the following main advantages: First, in the stirring and filtering stage of this equipment, the indium oxide raw material to be processed enters from the top of the tank and comes into contact with the upper filtering and impurity removal mechanism. The second motor drives the stirring frame to rotate at high speed, and the conical stirring auger fully stirs the raw material, making it evenly dispersed and in full contact with the filter screen. The scraping side frame rotates against the inner wall of the filter screen, which can not only prevent powder accumulation and blockage, but also accelerate the powder passing through the filter screen. After the qualified indium oxide is filtered through the filter screen, it is discharged through the inner discharge valve. Impurities are temporarily stored in the filter screen. At the same time, the rotation of the stirring auger makes the impurities roll up and down, further improving the stirring and filtering effect. After filtration, the filtered impurities can be discharged through the outer discharge valve.

[0014] 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. Example

[0015] Please refer to Figure 1-4 This embodiment of an indium oxide recovery and impurity removal device includes a support leg 1, a top ring 2 fixedly installed on the top of the support leg 1, a tank 5 fixedly installed on the inner side of the top ring 2, a rotating mechanism 3 fixedly installed on one side of the tank 5, a filtration and impurity removal mechanism 6 fixedly installed at both ends of the top of the rotating mechanism 3, one filtration and impurity removal mechanism 6 inserted into the upper end of the tank 5, and an external discharge valve 4 fixedly connected to the bottom of the tank 5. The rotating mechanism 3 includes a side support 31, which is fixedly installed on one side of the tank 5. A telescopic cylinder 32 is fixedly installed on the outer side of the side support 31. A first motor 33 is fixedly installed on the top of the telescopic cylinder 32. A top plate 34 is fixedly installed on the output end of the first motor 33. A filtration and impurity removal mechanism 6 is fixedly installed on both sides of the bottom of the top plate 34. During the application of this device, when the indium oxide recovery and impurity removal device is working, the indium oxide raw material to be processed enters the interior from the top of the tank 5. The filtration and impurity removal mechanism 6 located at the upper end of the tank 5 filters and removes impurities from it. When it is necessary to switch the filtration and impurity removal mechanism 6, the telescopic cylinder 32 is activated, driving the top plate 34 and the filtration and impurity removal mechanisms 6 at both ends of the top to move upward. Then the first motor 33 is activated. When machine 33 is running, it drives the top plate 34 to rotate, removing the clogged filter and impurity removal mechanism 6 from the tank 5. At the same time, another filter and impurity removal mechanism 6, which was waiting outside the tank 5, is moved into the tank 5. The locking block 65 at the bottom of the filter and impurity removal mechanism 6 engages with the locking groove 64 at the top inside the tank 5, achieving quick positioning and installation and continuing the filtration work. The filter and impurity removal mechanism 6 removed from the tank 5 can be cleaned and maintained. The entire process does not require stopping the machine for disassembly, ensuring uninterrupted operation of the indium oxide filtration process and improving the processing efficiency of the equipment. The qualified indium oxide after filtration is discharged through the inner discharge valve 69 at the bottom of the filter and impurity removal mechanism 6. Impurities are temporarily stored in the filter and impurity removal mechanism 6 and can eventually be discharged through the outer discharge valve 4 at the bottom of the tank 5.

[0016] Please refer to Figures 1-4The filtration and impurity removal mechanism 6 includes a hanger 61, which is fixedly installed on both sides of the bottom of the top plate 34. A fixed plate 62 is fixedly installed at the upper end of the hanger 61, and a second motor 63 is fixedly installed at the bottom of the fixed plate 62. A stirring rack 66 is fixedly installed at the output end of the second motor 63. A locking block 65 is fixedly installed at the bottom of the hanger 61, and a lifting ring 67 is fixedly installed on the inner side of the locking block 65. A filter screen 68 is fixedly installed at the bottom of the lifting ring 67. The top of the tank 5 has slots 64 arranged in a ring at equal intervals. The locking blocks 65 are inserted into the slots 64. The top view of the slots 64 and the locking blocks 65 are both convex. The filter screen 68 is conical in shape. An internal discharge valve 69 is fixedly installed at the bottom output end of the filter screen 68. The filter screen 68 is a stainless steel mesh cover. During the application of this device, its When the filtration and impurity removal mechanism 6 is working, the second motor 63 is installed in the hanger 61 through the fixed plate 62. Its output end drives the stirring frame 66 to rotate inside the conical stainless steel filter screen 68. After the indium oxide raw material to be processed enters the tank 5, the stirring frame 66 fully stirs the material, making it evenly dispersed and in full contact with the filter screen. The qualified indium oxide passes through the filter screen and is discharged through the bottom inner discharge valve 69. Impurities are temporarily stored inside the filter screen. When it is necessary to clean or replace the filter screen, the rotating mechanism 3 drives the hanger 61 to move upward, so that the locking block 65 disengages from the convex groove 64 at the top of the tank 5. Then the first motor 33 drives the top plate 34 to rotate, moving the clogged filter screen out of the tank 5. At the same time, the spare filter screen is moved to the working position. The locking block 65 is re-embedded in the groove 64 to achieve quick positioning and fixation, ensuring that the filtration process continues.

[0017] Please refer to Figures 2-4The stirring rack 66 includes a rotating shaft 661, which is fixedly installed at the bottom output end of the second motor 63. Scraping side frames 662 are fixedly installed in a ring at equal intervals on the upper surface of the outer surface of the rotating shaft 661. The outer side of the scraping side frames 662 is in close contact with the inner wall of the filter screen 68. The scraping side frames 662 are inclined as a whole, and the inner conical surfaces of the scraping side frames 662 and the filter screen 68 are parallel. A stirring auger 663 is fixedly installed at the lower end of the outer surface of the rotating shaft 661. The stirring auger 663 is conical as a whole, and its outer side is in close contact with the inner wall of the filter screen 68. A support bottom ring 7 is fixedly installed at the bottom of the support leg 1, and an anti-slip washer is fixedly connected to the support bottom ring 7. The bottom of the anti-slip washer has anti-slip texture. During application, when the stirring frame 66 is working, the second motor 63 drives the rotating shaft 661 to rotate, which in turn drives the scraping side frame 662 and the stirring auger 663 to rotate synchronously. The scraping side frame 662 fits against the inner wall of the filter screen 68. With its inclined structure and parallel conical surface design, it generates a scraping force during rotation, preventing indium oxide powder from accumulating and clogging on the filter screen surface. At the same time, the thrust generated by the inclined angle accelerates the material through the filter screen. The conical design of the stirring auger 663 fits against the inner wall of the filter screen. When rotating, it tumbles and stirs the material, making the powder evenly dispersed and fully contacting the filter screen, thus improving the filtration efficiency. The supporting bottom ring 7 cooperates with the anti-slip pads and anti-slip textures at the bottom to enhance the stability of the device, reduce shaking during operation, and ensure the smooth operation of the stirring and filtration process.

[0018] Operating Principle and Advantages: During the operation of this indium oxide recovery and impurity removal device, in the stirring and filtration stage, the indium oxide raw material to be processed can enter the interior through the top of the tank 5, first contacting the filtration and impurity removal mechanism 6 located at the upper end of the tank 5. When the second motor 63 is powered on, it runs, driving the stirring frame 66 to rotate at high speed at a set speed. The conical stirring auger 663 acts like the center of a vortex, fully stirring the powder raw material, breaking up material agglomerates, and achieving uniform dispersion, ensuring that every powder can fully contact the filter screen 68. At the same time, the scraping side frame 662, with its unique inclined structure, closely fits the inner wall of the conical filter screen 68 and rotates synchronously, not only constantly scraping the inner wall of the filter screen 68, but also effectively preventing powder from being trapped. The powder does not accumulate on the filter screen surface to form a clogging layer. It can also use the thrust generated by its own tilt angle to accelerate the movement speed of the powder on the filter screen surface and guide the powder to pass through the filter screen quickly. As the filtration process progresses, qualified indium oxide passes through the stainless steel filter screen 68 and is discharged in an orderly manner through the inner discharge valve 69 at the bottom. Impurities that cannot pass through the filter screen 68 are temporarily retained in the internal space of the filter screen. The setting of the stirring auger 663 can drive the rotating shaft 661 to drive the stirring auger 663 to rotate during the operation of the second motor 63. It can play a good tumbling and stirring role inside the filter screen 68. The rotation of the auger can cause the filtered impurities inside the filter screen 68 to tumble up and down, which can improve its stirring and filtration effect. After filtration, the material can be discharged by opening the outer discharge valve 4. During the cleaning and maintenance process, when the filter screen 68 needs cleaning due to decreased filtration efficiency caused by impurities, the telescopic cylinder 32 can be activated. The telescopic cylinder 32 can be connected to the air supply pipeline in the factory production workshop. Activating the telescopic cylinder 32 under the command of the control system will quickly move the top plate 34, along with the filtration and impurity removal mechanism 6, upwards. Then, activating the first motor 33 will rotate the top plate 34, completely removing the clogged filter screen 68 from the working area of ​​the tank 5. At this point, another filtration and impurity removal mechanism 6, which is pre-positioned outside the tank 5, moves precisely into the tank 5 under the reverse push of the telescopic cylinder 32 and the rotation adjustment of the first motor 33. Its bottom locking block 65 is aligned with the top of the tank 5. The convex-shaped slot 64 fits perfectly, enabling quick positioning and stable installation, allowing for immediate takeover and ensuring uninterrupted operation of the indium oxide filtration process. The filter screen 68, removed from the tank 5, is out of the operating environment of the device, allowing operators to perform a thorough cleaning in a safe and convenient manner. This can be done using conventional methods such as high-pressure washing and brush cleaning, or by using the residual scraping force from the side frame 662 to help remove stubborn impurities adhering to the inner wall of the filter screen. At the same time, driving the agitator 663 to rotate in the opposite direction can drive the filtered large particles of impurities from top to bottom. Opening the internal discharge valve 69 allows the impurities to be discharged. The entire cleaning and maintenance process does not require complex disassembly and assembly of the device, significantly reducing downtime and improving the processing efficiency of the equipment. The support leg 1 of this device is made of Q235B steel, with a diameter of 80-100mm and a height of 600-800mm. The bottom support ring 7 has a diameter of 120-150mm.
