[0020] 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.

[0021] Example 1

[0022] refer to Figure 1 This embodiment proposes a cleaning device for the inner wall of a titanium sponge reactor, including: a support cylinder 11 that cooperates with the inlet of the reactor 8. The inner wall of the support cylinder 1 is provided with a first annular platform 2 and a second annular platform 3 arranged at intervals along its circumference. The upper end of the first annular platform 2 is provided with a first driving component 4 that is rolledly connected to it. The first driving component 4 is fixedly connected to a second driving component 6 inside the support cylinder 1 through a telescopic component 5. The second driving component 6 is rotatably connected to the second annular platform 3 through a clamping component 9. The lower end of the second driving component 6 is fixedly connected to a scraper component 7.

[0023] After the production of sponge titanium is completed, reactor 8 is hoisted onto support 503. After the sponge titanium agglomerates in reactor 8 are removed, the cleaning device proposed in this embodiment is used to clean the inner wall of reactor 8. During cleaning, the cleaning device is first hoisted to the upper end of reactor 8 so that the lower end of support cylinder 1 matches the opening of reactor 8; the telescopic component 5 is adjusted so that the scraper component 7 contacts the inner wall of the cleaning device, with the contact position located at the clean position above the "roasted titanium" on the inner wall; the scraper component 7 is driven by the second drive component 6 to move downward along the inner wall of reactor 8 to the bottom of reactor 8 to perform longitudinal cleaning of the inner wall of reactor 8. After one cleaning is completed, the second drive component 6 is used to clean the inner wall of reactor 8. The second drive assembly 6 drives the scraper assembly 7 to return. Afterwards, the first drive assembly 4 can drive the scraper assembly 7 to perform multiple circumferential cleanings on the inner wall of the reactor 8. After each cleaning cycle, the second drive assembly 6 drives the scraper assembly 7 to move longitudinally on the inner wall of the reactor 8 to perform the next cleaning cycle. The cleaning areas of adjacent two cycles are connected, and the starting point of each cycle is located in the longitudinally cleaned area to ensure cleaning efficiency and quality. Alternatively, the first drive assembly can drive the scraper assembly 7 to rotate circumferentially along the inner wall of the reactor 8 by an angle, and then the second drive assembly 6 drives the scraper assembly 7 to perform the next longitudinal cleaning cycle. The cleaning areas of adjacent two cycles are connected.

[0024] In the deformed position of reactor 8, or after the scraper assembly 7 has been worn for a long time, the telescopic component 5 can be adjusted to make the scraper assembly 7 thoroughly clean the inner wall of reactor 8.

[0025] Specifically, an annular track 201 is provided around the upper end of the first annular platform 2. The first drive assembly 4 includes a motor 401 and a rolling device. The rolling device includes a roller 402 that matches the annular track 201. Support shafts are provided on both sides of the roller 402. The height of the support shafts is higher than the upper end of the support cylinder 1. When the roller 402 rotates, it does not conflict with the support cylinder 1 and does not affect the rotation of the roller 402. The support shaft on the outer side of the roller 402 is connected to the output shaft of the motor 401. The support shafts on both sides of the roller 402 are also connected to the second drive assembly 6 through the telescopic assembly 5.

[0026] In this embodiment, after the motor 401 is started, it drives the roller 402 to rotate along the annular track 201, which in turn drives the second drive assembly 6 and the scraper assembly 7 to move circumferentially along the inner wall of the reactor 8. The support shaft on the outer side of the roller 402 is connected to the output shaft of the motor 401 through a reducer. The motor 401 is a servo motor 401, which allows the roller 402 to rotate at a slower speed, making it easier to control the cleaning process and ensuring the safety of the cleaning process.

[0027] The telescopic assembly 5 includes a telescopic mechanism 501, and the second drive assembly 6 includes a cylinder 601. A first clamp 502 is fitted onto one end of the cylinder bottom of the cylinder 601. The piston of the cylinder 601 is connected to the scraper assembly 7 through a first connecting rod 602. The telescopic mechanism 501 extends radially along the support cylinder 1. One end of the telescopic mechanism 501 is fixedly connected to the first drive assembly through a bracket 503 located on the upper end of the roller 402, and the other end is fixedly connected to the first clamp 502. The bracket 503 is a U-shaped bracket. The two opposite walls of the bracket 503 are rotatably connected to the support shafts on both sides of the roller 402 through bearings, which can ensure the stability of the bracket 503 without affecting the rotation of the roller 402.

[0028] The inner wall of the second annular platform 3 is provided with a guide groove 301, and a support block 302 is provided in the guide groove 301. The clamp assembly 9 includes a second clamp 901 that is sleeved on the cylinder 601 near the piston end. The second clamp 901 is fixedly connected to the support block 302 through a second connecting rod 902. Universal wheels are provided between the upper end of the support block 302 and the upper wall of the guide groove 301, and between the lower end of the support block 302 and the lower wall of the guide groove 301.

[0029] In this embodiment, the guide groove 301 and the annular track 201 work together to support the cleaning device. When the first drive component 4 drives the second drive component 6 and the scraper component 7 to make a circular motion, the support block 302 also makes a circular motion along the guide groove 301 under the action of the universal wheel. This provides support without affecting the rotation of the scraper component 7. The width of the guide groove 301 is greater than the width of the support block 302. This is to ensure that the support block 302 can make a smooth circular motion along the guide groove 301 without affecting the extension and retraction process of the telescopic mechanism 501.

[0030] The scraper assembly 7 includes a scraper body 701, one end of which is fixedly connected to the first connecting rod 602, and the other end is fixedly connected to the blade head 702. When cleaning the inner wall of the reactor 8, the telescopic assembly 5 is adjusted so that the blade head 702 contacts the inner wall of the reactor 8. The blade head 702 is arc-shaped along the width direction, and the curvature of the blade head 702 is the same as the curvature of the inner wall of the reactor 8. In this way, when the blade head 702 contacts the inner wall of the reactor 8, it can fit snugly against the inner wall of the reactor 8, ensuring the cleaning effect and quality.

[0031] In this embodiment, the arc length of the cutter head 702 should not be too long, preferably 100mm to 150mm, to ensure the strength of the cutter head 702 while facilitating cleaning.

[0032] The distance between the annular track 201 and the inner wall of the support cylinder 1 is preferably 50mm to 100mm, so that the roller 402 does not conflict with the inner wall of the support cylinder 1 during the rotation of the roller 402.

[0033] The inner diameter of the support cylinder 1 is preferably the same as that of the reactor 8. After the cleaning device is installed on the reactor 8, the support cylinder 1 is coaxial with the reactor 8. The lower end of the support cylinder 1 is provided with a connecting flange 10 that matches the flange at the inlet of the reactor 8. After the cleaning device is installed on the reactor 8, the connecting flange 10 is connected to the flange at the inlet of the reactor 8 by bolts to ensure a reliable connection between the reactor 8 and the cleaning device.

[0034] In the above embodiments, the dimensions of each component and the distance between each component can be determined according to design requirements.

[0035] The specific embodiments of this utility model are provided to enable those skilled in the art to understand or implement this utility model. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this utility model.
