Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, and in particular to a high-purity arsenic removal device. Background Technology

[0002] Arsenic is an important semiconductor material. In the semiconductor industry, high-purity arsenic is used to manufacture compound semiconductors, such as gallium arsenide. Gallium arsenide is an important compound semiconductor material with excellent electrical properties such as high electron mobility and direct bandgap. It is widely used in optoelectronic devices (such as light-emitting diodes and laser diodes) and high-frequency electronic devices (such as microwave devices). With the development of modern electronic technology towards high frequency, high speed, high power and miniaturization, the demand for high-purity arsenic is increasing. In the photovoltaic field, arsenic-containing compounds also have certain applications. In order to improve the conversion efficiency and stability of photovoltaic cells, the purity requirements of arsenic are also very high.

[0003] The high-purity arsenic removal device mainly consists of a reaction tank, a feeding component, a filtration component, and a discharge component. Its working principle is based on a chemical reaction method. First, the arsenic raw material containing impurities is dissolved in a suitable solvent in the reaction tank. Different reactions are carried out according to the characteristics of different impurities. For example, if metallic impurities are present, a redox reaction is used to oxidize them to a higher oxidation state with the help of an oxidizing agent, and then a precipitant is added to precipitate them. If acidic or alkaline impurities are present, an acid-base neutralization reaction is used to generate salts for subsequent separation. Finally, filtration is used to remove the impurity products generated in the reaction from the arsenic-containing solution, thereby obtaining high-purity arsenic.

[0004] In current high-purity arsenic removal processes, when high-purity arsenic materials are injected, the powdery form of the material easily accumulates, adheres to the inner wall, and causes blockages inside the storage tank. This not only interferes with the smooth transport of materials and seriously affects subsequent feeding operations, leading to interruption or a significant reduction in efficiency of the entire removal process, but also causes equipment failures, increasing maintenance costs and production downtime. Therefore, a high-purity arsenic removal device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a high-purity arsenic removal device, which aims to improve the problem of easy accumulation and blockage inside the storage tank in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A high-purity arsenic removal device includes a tank, a storage box fixedly connected to the top of the tank, a feeding mechanism inside the storage box, a vibration mechanism outside the storage box, a control mechanism at the top of the tank, a stirring mechanism inside the tank, and a filtration mechanism at the front end of the tank.

[0008] The vibration mechanism includes a fixed box, which is fixedly connected to the outside of the storage box. A sliding block is slidably connected inside the fixed box. A telescopic column is fixedly connected to the top of the sliding block. A telescopic spring is sleeved on the outside of the telescopic column.

[0015] As a further description of the above technical solution:

[0016] The control mechanism includes a control block, the bottom end of which is fixedly connected to the top of the tank, a rotating shaft rotatably connected to the front end of the control block, a control rod fixedly connected to the outside of the rotating shaft, a fixed column fixedly connected to the inside of the tank, a sliding column slidably connected to the inside of the fixed column, a float fixedly connected to the bottom end of the sliding column, a sliding groove being formed inside the sliding column, and the control rod slidably connected to the inside of the sliding groove.

[0017] As a further description of the above technical solution:

A second rotating column is fixedly connected to the drive end of the stirring mechanism, and a stirring rod is fixedly connected to the outside of the second rotating column.

[0019] As a further description of the above technical solution:

[0024] 1. In this utility model, when the rotating column rotates, the eccentric wheel intermittently presses the striking rod, and the telescopic spring pushes the sliding block, so that while the feeding plate rotates, the striking rod intermittently strikes the receiving rod, thereby causing the storage box and the feeding plate to vibrate, achieving the effect of preventing powder from adhering, accumulating and clogging, and ensuring the stable operation of the processing.

This improves the stability and reliability of the entire high-purity arsenic removal process, while also greatly reducing the tediousness and errors of manual operation, providing convenience for large-scale continuous production of high-purity arsenic.

[0032] 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.

[0033] Reference Figures 1 to 3 This utility model provides an embodiment of a high-purity arsenic removal device, comprising a tank 1, which serves as the core reaction space for the entire removal process, providing a site for the reaction between high-purity arsenic and the reaction solution. A storage box 2 is fixedly connected to the top of the tank 1, which stores the high-purity arsenic powder to be removed, ensuring that the powder can enter the tank 1 in an orderly manner for reaction. A feeding mechanism 3 is provided inside the storage box 2, which can quantitatively feed the high-purity arsenic powder in the storage box 2 to ensure the continuous progress of the reaction. The feeding mechanism 3 includes a rotating column 301, which is rotatably connected to the inside of the storage box 2. Multiple feeding plates 302 are fixedly connected to the outside of the rotating column 301. As the rotating column 301 rotates, the feeding plates 302 can uniformly convey the powder in the storage box 2 downwards, realizing the feeding operation of the powder. A motor 303 is fixedly connected to the front end of the rotating column 301, which serves as a drive source to provide power for the rotation of the rotating column 301.

[0034] The storage box 2 is equipped with a vibration mechanism 4 on its exterior. The vibration mechanism 4 can effectively avoid blockage and uneven feeding during the feeding process. The vibration mechanism 4 includes a fixed box 402, which is fixedly connected to the exterior of the storage box 2 to provide support and fixation for the entire vibration mechanism 4. A sliding block 405 is slidably connected inside the fixed box 402. The sliding of the sliding block 405 inside the fixed box 402 is one of the key actions to achieve the vibration effect. A telescopic column 404 is fixedly connected to the top of the sliding block 405. The telescopic column 404 plays the role of guiding and stabilizing the sliding block 405 to ensure its stability during the sliding process.

[0035] A telescopic spring 403 is sleeved on the outside of the telescopic column 404. The telescopic spring 403 plays the role of storing and releasing energy during the entire vibration process. A striking rod 406 is fixedly connected to the outside of the sliding block 405. The striking rod 406 performs a striking action under the drive of the sliding block 405. A receiving rod 407 is fixedly connected to the outside of the storage box 2. The outside of the striking rod 406 is in contact with the outside of the receiving rod 407. When the striking rod 406 hits the receiving rod 407, it will cause the storage box 2 to vibrate. An eccentric wheel 401 is fixedly connected to the outside of the rotating column 301. The eccentric wheel 401 is in contact with the outside of the striking rod 406.

[0036] Reference Figure 1 , Figure 2 and Figure 4 The top of the tank body 1 is equipped with a control mechanism 5. The control mechanism 5 can automatically control the injection of powder and solution to ensure that the reaction is carried out under suitable conditions and improve processing efficiency. The control mechanism 5 includes a control block 502. The bottom end of the control block 502 is fixedly connected to the top of the tank body 1 and is the main component of the entire control mechanism 5. The front end of the control block 502 is rotatably connected to a rotating shaft 503. A control rod 505 is fixedly connected to the outside of the rotating shaft 503. The rotating shaft 503 provides a fulcrum for the rotation of the control rod 505. The control rod 505 controls the control block 502 by cooperating with the sliding groove 504. A fixed column 506 is fixedly connected inside the tank body 1.

[0037] A sliding column 501 is slidably connected inside the fixed column 506. A float 507 is fixedly connected to the bottom end of the sliding column 501. The sliding column 501 slides within the fixed column 506 as the float 507 rises and falls. The float 507 floats at the top of the solution and rises and falls with the liquid level. A sliding groove 504 is provided inside the sliding column 501. The control rod 505 is externally slidably connected inside the sliding groove 504. When the float 507 moves the sliding column 501 to a designated position as the water level rises and falls, the control rod 505 touches the inner wall of the sliding groove 504, causing the control rod 505 to rotate upward. This controls the control block 502 to adjust the injection of powder and solution. At the same time, the floating float 507 can control the on / off switch of the rotating shaft 503, ensuring that the water level of the reaction solution is always at a designated level, guaranteeing a complete reaction. This automatic control method greatly reduces the effort required for manual control and significantly improves processing efficiency.

[0038] The tank 1 is equipped with a stirring mechanism 6, which can fully mix the reaction solution and accelerate the reaction process. The stirring mechanism 6 includes a second motor 601, which is fixedly connected to the bottom of the tank 1 to provide power for the entire stirring mechanism 6. The driving end of the stirring mechanism 6 is fixedly connected to a second rotating column 602, which rotates under the drive of the second motor 601. A stirring rod 603 is fixedly connected to the outside of the second rotating column 602. When the second rotating column 602 rotates, the stirring rod 603 rotates slowly inside the tank 1 to achieve full mixing of the reaction solution and greatly improve the reaction rate.

[0039] A filter mechanism 7 is installed at the front end of the tank 1. The filter mechanism 7 can filter impurities from the reaction solution to obtain a high-purity arsenic solution. The filter mechanism 7 includes an outlet pipe 701, the rear end of which is fixedly connected to the front end of the tank 1, responsible for exporting the reacted solution from the tank 1. A filter box 702 is fixedly connected to the front end of the outlet pipe 701, providing space for impurity filtration. A filter screen 703 is fixedly connected inside the filter box 702, which can intercept impurities in the solution. The solid-liquid separation process is as follows: the front end of the filter box 702 is fixedly connected to the outlet 705, which is used to discharge the filtered high-purity arsenic solution. The outlet 705 is fixedly connected to the outside of the outlet 705, and the water pump 704 controls the pressure of the liquid, so that the reaction solution passes through the filter screen 703. The filtered high-purity arsenic solution flows through the outlet 705 to a designated location for collection. The residual impurities fall into the interior of the filter box 702, thereby achieving the effect of impurity removal and finally obtaining a high-purity arsenic solution.

[0040] Working principle: When the operator needs to remove impurities from a batch of high-purity arsenic, the high-purity arsenic powder is placed into the storage box 2. At this time, by starting motor 303, the motor 303 drives the rotating column 301 to rotate inside the storage box 2, thereby causing the feeding plate 302 to rotate inside the storage box 2, realizing the powder feeding operation. When the rotating column 301 rotates, it drives the eccentric wheel 401 to rotate. The eccentric wheel 401, when rotating, presses against the striking rod 406, causing the sliding block 405 to slide inside the fixed box 402, simultaneously... When the telescopic spring 403 is compressed, and the eccentric wheel 401 rotates to the designated position and releases the pressure on the striking rod 406, the elastic potential energy accumulated by the telescopic spring 403 will push the sliding block 405 to slide downwards quickly, so that the striking rod 406 and the struck rod 407 will collide, causing the storage box 2 to vibrate as a whole. This will remove the powder adhering to the inside of the storage box 2 and the outside of the feeding plate 302, avoiding uneven feeding and blockage. The reaction solution will be injected into the inside of the tank 1 through the pipe at the front end of the tank 1 to react with the powder.

[0041] When the powder and solution react inside the tank 1, the float 507 floats at the top of the solution and rises and falls with the liquid level, causing the sliding groove 504 to slide inside the fixed column 506. When it reaches the designated position, the control rod 505 touches the inner wall of the sliding groove 504, causing the control rod 505 to rotate upward, thereby controlling the control block 502 to adjust the injection operation of the powder and solution. At the same time, the float can control the switch of the rotating shaft 503 to keep the water level of the reaction solution at the designated level to ensure a complete reaction. Through automatic control, the effort of manual control is reduced and the processing efficiency is improved.

[0042] During the reaction, motor 601 controls the rotating column 602 to rotate slowly, causing the stirring rod 603 to rotate slowly inside the tank 1, achieving thorough mixing of the reaction solution and increasing the reaction rate. The well-reacted solution is discharged through the outlet pipe 701 into the filter box 702. At this time, the water pump 704 controls the liquid pressure, causing the reaction solution to be filtered through the filter screen 703. The filtered high-purity arsenic solution flows through the outlet 705 to a designated location for collection. Residual impurities fall into the filter box 702, thus achieving the effect of impurity removal.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
