Description

Technical Field

[0001] The present invention relates to the technical field of metal smelting, and particularly to a cleaning device and a cleaning method for the inner wall of a titanium sponge reactor. Background Art

[0002] During the process of producing titanium sponge by the "magnesium thermal reduction method", after the produced titanium sponge ingot is taken out of the reactor, a layer of titanium skin, abbreviated as "scale titanium", will adhere to the inner wall of the reactor. Before the reactor is put into operation again, the "scale titanium" needs to be cleaned up. Otherwise, it will affect the quality of the titanium sponge product in the next batch. With the development of titanium sponge towards large furnaces, the diameter and length of the reactor are continuously increasing, while the cleaning work still uses traditional manual handheld pneumatic picks to clean the reactor one by one, resulting in low cleaning efficiency, high labor intensity, and incomplete cleaning. Summary of the Invention

[0010] Specifically, the scraper assembly includes a scraper body, one end of which is fixedly connected to the second driving assembly, and the other end of which is fixedly connected to the blade head.

[0011] Specifically, the cutter head is arc-shaped along the width direction, the curvature of the cutter head is the same as the curvature of the inner wall of the reactor, and the arc length of the cutter head is 100 mm to 150 mm.

[0012] Specifically, the distance between the annular track and the inner wall of the support tube is 50 mm to 100 mm.

[0013] Specifically, the inner diameter of the support tube is the same as the inner diameter of the reactor, and a connecting flange matching with the flange at the mouth of the reactor is arranged at the lower end of the support tube.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Example 1

[0026] refer to Figure 1 The present embodiment proposes a cleaning device for the inner wall of a sponge titanium reactor, comprising: a support tube 11 matched with the mouth of a reactor 8, a first annular platform 2 and a second annular platform 3 are arranged on the inner wall of the support tube 1 along its circumference, and a first driving component 4 is provided at the upper end of the first annular platform 2 to be rollingly connected thereto, the first driving component 4 is fixedly connected to the second driving component 6 on the inner side of the support tube 1 through a telescopic component 5, the second driving component 6 is rotationally connected to the second annular platform 3 through a clamping hoop component 9, and the lower end of the second driving component 6 is fixedly connected to the scraper component 7.

[0027] After the production of sponge titanium is completed, the reactor 8 is hoisted onto the bracket 503. After the sponge titanium lumps in the reactor 8 are hoisted out, the cleaning device proposed in this embodiment is used to clean the inner wall of the reactor 8. When cleaning, the cleaning device is first hoisted to the upper end of the reactor 8 so that the lower end of the support tube 1 is matched with the mouth of the reactor 8; the telescopic component 5 is adjusted to make the scraper component 7 contact with the inner wall of the cleaning device, and the contact position is located at a clean position on the upper part of the "pot crust 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 the reactor 8 to the bottom of the reactor 8, and the inner wall of the reactor 8 is cleaned longitudinally. After one cleaning is completed, ... The second driving assembly 6 drives the scraper assembly 7 to return, and then the first driving assembly 4 can drive the scraper assembly 7 to perform circumferential cleaning of the inner wall of the reactor 8 for multiple times. After each cleaning cycle, the second driving 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 the two adjacent weeks are connected, and the starting point of each cycle is located in the area that has been longitudinally cleaned to ensure the cleaning efficiency and cleaning quality. The scraper assembly 7 can also be driven by the first driving assembly to rotate an angle along the circumference of the inner wall of the reactor 8, and then the scraper assembly 7 is driven by the second driving assembly 6 to perform the next longitudinal cleaning cycle, and the two adjacent cleaning areas are connected.

[0028] When the reactor 8 is deformed, or the scraper assembly 7 is worn out after long-term use, the telescopic assembly 5 can be adjusted so that the scraper assembly 7 can clean the inner wall of the reactor 8 thoroughly.

[0029] Specifically, a circular track 201 is arranged along the circumference of the upper end of the first circular table 2, the first driving component 4 includes a motor 401 and a rolling device, the rolling device includes a roller 402 matching the circular track 201, support shafts are arranged on both sides of the roller 402, the height of the support shaft is higher than the upper end of the support tube 1, when the roller 402 rotates, it does not conflict with the support tube 1, and does not affect the rotation of the roller 402, the support shaft outside the roller 402 is connected to the output shaft of the motor 401, and the support shafts on both sides of the roller 402 are also connected to the second driving component 6 through the telescopic component 5.

[0030] In this embodiment, after the motor 401 is started, it drives the roller 402 to rotate along the annular track 201, and then drives the second drive assembly 6 and the scraper assembly 7 to perform a circumferential movement along the inner wall of the reactor 8. Among them, the support shaft on the outer side of the roller 402 is connected to the output shaft of the motor 401 through a speed reducer, and the motor 401 is a servo motor 401. In this way, the rotation speed of the roller 402 can be slower, which is convenient for controlling the cleaning process and can also ensure the safety of the cleaning process.

[0031] The telescopic assembly 5 includes a telescopic mechanism 501. The second drive assembly 6 includes a cylinder 601. One end of the bottom of the cylinder 601 is sleeved with a first hoop 502. The piston of the cylinder 601 is connected to the scraper assembly 7 through a first connecting rod 602. The telescopic direction of the telescopic mechanism 501 is along the radial direction of the support cylinder 1. One end of the telescopic mechanism 501 is fixedly connected to the first drive assembly through a bracket 503 arranged at the upper end of the roller 402, and the other end is fixedly connected to the first hoop 502. The bracket 503 is a U-shaped frame. The two opposite walls of the bracket 503 are respectively rotatably connected to the support shafts on both sides of the roller 402 through bearings, which can not only ensure the stability of the bracket 503 but also not affect the rotation of the roller 402.

[0032] A guide groove 301 is provided on the inner wall of the second annular platform 3. A support block 302 is arranged in the guide groove 301. The hoop assembly 9 includes a second hoop 901 sleeved on the cylinder 601 near the piston end. The second hoop 901 is fixedly connected to the support block 302 through a second connecting rod 902. Universal wheels are arranged 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.

[0033] In this embodiment, the guide groove 301 and the annular track 201 cooperate to support the cleaning device. When the first drive assembly 4 drives the second drive assembly 6 and the scraper assembly 7 to perform a circular motion, the support block 302 also performs a circular motion along the guide groove 301 under the action of the universal wheels, which not only plays a supporting role but also does not affect the rotation of the scraper assembly 7. Among them, the width of the guide groove 301 is greater than the width of the support block 302. While ensuring that the support block 302 can smoothly perform a circular motion along the guide groove 301, it does not affect the telescopic process of the telescopic mechanism 501.

[0034] The scraper assembly 7 includes a scraper main body 701. One end of the scraper main body 701 is fixedly connected to the first connecting rod 602, and the other end is fixedly connected to the tool head 702. When cleaning the inner wall of the reactor 8, the telescopic assembly 5 is adjusted to make the tool head 702 contact the inner wall of the reactor 8. The tool head 702 is arc-shaped in the width direction, and the radian of the tool head 702 is the same as the radian of the inner wall of the reactor 8. In this way, when the tool head 702 contacts the inner wall of the reactor 8, it can fit with the inner wall of the reactor 8 to ensure the cleaning effect and quality.

[0035] In this embodiment, the arc length of the cutter head 702 should not be too long, preferably 100 mm to 150 mm, so as to ensure the strength of the cutter head 702 and facilitate cleaning.

[0036] The distance between the annular track 201 and the inner wall of the support tube 1 is preferably 50 mm to 100 mm, and during the rotation of the roller 402 , the roller 402 does not conflict with the inner wall of the support tube 1 .

[0037] The inner diameter of the support tube 1 is preferably the same as the inner diameter of the reactor 8, and after the cleaning device is installed on the reactor 8, the support tube 1 is coaxial with the reactor 8, and a connecting flange 10 is provided at the lower end of the support tube 1 to match the flange at the mouth 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 mouth of the reactor 8 by bolts to ensure a reliable connection between the reactor 8 and the cleaning device.

[0038] In the above embodiments, the size of each component and the distance between the components can be determined according to design requirements.

[0039] The specific embodiments of the present invention enable those skilled in the art to understand or implement the present invention. Various modifications to these embodiments will be 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 the present invention.
