Description

Technical Field

[0001] This utility model relates to the field of crystallization scraping technology, and in particular to a pneumatic scraping device for rare earth crystallization. Background Technology

[0002] In the rare earth production process, rare earth ions in the solution crystallize through precipitation, evaporation and concentration, and cooling. These crystals adhere to the inner wall of the reactor and need to be scraped off and collected by a scraping device before being applied in fields such as electronics, energy, and environmental protection.

[0003] The scraping devices currently used involve manual scraping with long-handled scrapers or other tools inside the reactor. However, this method is labor-intensive, and the residual chemical gases inside the reactor may cause potential harm to the human body, posing certain safety risks. Some scraping devices use nozzles to convert high-pressure water into high-speed water jets, using the powerful impact force generated by the water jets to break up and remove the crystals. However, rare earth crystals have high hardness and strong adhesion, resulting in poor removal effectiveness.

[0004] Therefore, based on the above situation, we propose a pneumatic scraping device for rare earth crystals to solve the above problems. Utility Model Content

[0005] This invention provides a pneumatic scraping device for rare earth crystals to solve the problems existing in the prior art.

[0006] The technical problem solved by this utility model is achieved by the following technical solution:

[0007] A pneumatic scraping device for rare earth crystals includes a scraping component, a pulsed pneumatic mechanism, and a lifting drive component. The scraping component is movably disposed inside a reactor for scraping rare earth crystals on the inner wall of the reactor. The pulsed pneumatic mechanism is connected to the scraping component via a receiving plate and is used to drive the scraping component to perform high-frequency reciprocating motion inside the reactor under the action of pulsed air pressure, thereby scraping the rare earth crystals on the inner wall of the reactor. The lifting drive component is disposed at the upper end of the pulsed pneumatic mechanism and is used to drive the pulsed pneumatic mechanism and the scraping component to move up and down along the axial direction of the reactor.

[0008] Preferably, the scraper includes a support portion connected to the receiving plate and a blade portion connected to the bottom of the support portion, the blade portion being serrated.

[0009] Preferably, the pulse pneumatic mechanism includes a pneumatic chamber connected to the output end of the lifting drive component and a piston movably connected inside the pneumatic chamber. The receiving plate is connected to the bottom of the piston, and a spring is connected between the piston and the pneumatic chamber.

[0010] Preferably, the outer wall of the support is provided with an auxiliary scraping ring, which is attached to the inner wall of the reactor.

[0011] Preferably, the sidewall of the receiving plate is attached to the inner wall of the reactor.

[0012] Preferably, a protective ring is provided at the bottom of the pneumatic cavity.

[0013] The beneficial effects of this utility model are as follows: the pulse pneumatic mechanism drives the scraper to perform high-frequency reciprocating motion inside the reactor, so that the scraper continuously acts on the crystallization on the inner wall of the reactor, generating an impact force on the crystallization surface to achieve the scraping of the crystals. At the same time, the lifting drive drives the pulse pneumatic mechanism and the scraper to continuously descend, flexibly adapting to the crystal cleaning needs at different heights and improving the cleaning efficiency.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0022] Reference Figures 1-5As shown, a pneumatic scraping device for rare earth crystals includes a scraper 1, which is disposed inside a reactor 2. After rare earth crystals form inside the reactor 2, the scraper can scrape off the crystals on the inner wall of the reactor 2. A pulse pneumatic mechanism 3 is connected to the upper end of the scraper 1. The pulse pneumatic mechanism 3 drives the scraper 1 to perform high-frequency reciprocating motion inside the reactor 2 under pulsed air pressure. The high-frequency reciprocating motion of the scraper 1 continuously impacts the rare earth crystals, similar to a woodpecker pecking wood. This high-frequency, small-amplitude reciprocating motion of the scraper 1 can more efficiently break the structure of the rare earth crystals with its impact energy, allowing the rare earth crystals to fall off the inner wall of the reactor 2. Simultaneously, for flexibility and adaptability... To meet the needs of cleaning crystals at different heights, a lifting drive component 5 is installed at the upper end of the pulse pneumatic mechanism 3. The lifting drive component 5 can be a hydraulic telescopic rod, etc. In actual use, a stabilizing frame can be installed on the reactor 2 to support the lifting drive component 5 and maintain its stability during use. By keeping the lifting drive component 5 at a suitable descent speed, it continuously drives the pulse pneumatic mechanism 3 and the scraper 1 to descend. Together with the pulse pneumatic mechanism 3, they continuously act on the rare earth crystals at different heights on the inner wall of the reactor 2 to effectively scrape off the rare earth crystals and improve the scraping efficiency. A discharge port can be set at the bottom of the reactor 2. The scraped rare earth crystals can be discharged from the discharge port and collected for subsequent industrial production.

[0023] Reference Figure 5 As shown, further, in order to improve the scraping efficiency of rare earth crystals, the scraper 1 includes a support part 11 connected to the receiving plate 4 and a blade part 12 connected to the bottom of the support part 11. During use, the blade part 12 continuously contacts the rare earth crystals. The blade part 12 is usually quite sharp and can act on the rare earth crystals with a small contact area. The blade part 12 is serrated. Under the same pressure, a small contact area will generate a large pressure, which makes it easier to cut into the interior of the rare earth crystals and scrape the rare earth crystals off the inner wall of the reactor 2. At the same time, the support part 11 connects the receiving plate 4 and the blade part 12, which plays a supporting role and can evenly transmit the force from the receiving plate 4 to the blade part 12, so that the scraper 1 maintains a stable structure during operation and is not prone to deformation or shaking. This ensures that the blade part 12 always maintains good contact with the rare earth crystals, improving the consistency and efficiency of scraping.

[0024] Reference Figure 3As shown, further, in order to drive the scraper 1 to perform high-frequency reciprocating motion inside the reactor 2, the pulse pneumatic mechanism 3 includes a pneumatic chamber 31 connected to the output end of the lifting drive 5 and a piston 32 movably connected inside the pneumatic chamber 31. In use, an air inlet is provided at the upper end of the pneumatic chamber 31, and the air inlet can be connected to an external air compressor through a pipe. The air compressor then delivers compressed air into the interior of the pneumatic chamber 31. When air is inlet, the piston 32 abuts against the receiving plate 4 connected to it, causing the scraper 1 to move downward and act on the rare earth crystals. When air is released, under the elastic action of the spring 6 between the piston 32 and the pneumatic chamber 31, the scraper 1, the receiving plate 4, and the piston 32 move upward, thereby realizing the continuous reciprocating motion of the scraper 1 and improving the scraping efficiency of rare earth crystals.

[0025] Reference Figure 4 , Figure 5 As shown, in order to scrape off the rare earth crystal residue remaining on the inner wall of the reactor 2, an auxiliary scraping ring 7 is provided on the outer wall of the support part 11. The auxiliary scraping ring 7 is attached to the inner wall of the reactor 2. When the lifting drive 5 drives the scraper 1 to descend, the auxiliary scraping ring 7 can perform secondary scraping on the small amount of crystals remaining on the inner wall of the reactor 2 after the blade 12 has scraped off. It can fill the possible scraping blind spots of the blade 12, further clean the rare earth crystals attached to the reactor wall, make the scraping more thorough, and reduce the amount of crystal residue.

[0026] Reference Figure 2 As shown, furthermore, in order to reduce the shaking of the scraper 1, the side wall of the receiving plate 4 is attached to the inner wall of the reactor 2, which can provide direct support for the scraper 1 when it is working. This support method can effectively limit the horizontal displacement of the scraper 1, so that the scraper 1 remains stable during the scraping of rare earth crystals and avoids the scraping effect being affected by shaking.

[0027] Reference Figure 3 , Figure 4 As shown, in order to further protect the pneumatic cavity 31, a protective ring 8 is provided at the bottom of the pneumatic cavity 31. The protective ring 8 can be made of rubber, silicone or other materials. When the spring 6 drives the receiving plate 4 and the scraper 1 to move upward, when the receiving plate 4 comes into contact with the pneumatic cavity 31, the elasticity of the protective ring 8 can buffer the receiving plate 4 and the pneumatic cavity 31, reducing the collision between the two.
