Description

Technical Field

[0001] The invention relates to the technical field of titanium sponge production, in particular to rapid furnace cleaning equipment for a large titanium sponge reactor. Background Art

[0002] The magnesium-thermal reduction method for industrial titanium sponge production involves a redox reaction between titanium tetrachloride and high-temperature molten magnesium. The resulting titanium sponge is primarily composed of titanium lumps and wall-climbing titanium. The edges of the titanium lumps are separated from the reactor by a certain distance and can be lifted out and separated using a crane. During the magnesium-thermal reduction process, the intense exothermic reaction causes the wall-climbing titanium to have a high iron content, causing it to adhere to the inner wall of the reactor with strong adhesion. Small amounts of magnesium chloride and low-valent titanium may also remain on the reactor wall.

[0003] Currently, the wall-climbing titanium cleaning of sponge titanium reactors is mostly done manually by directly hitting with a jackhammer. This method is extremely labor-intensive and inefficient, and it is easy to damage the titanium infiltration layer of the reactor. The cleaning effect also varies from person to person. Some machines are also used for cleaning, but the existing equipment is inefficient, cumbersome to operate, and has a single operating mode. It is relatively limited in the application of large-scale reactors. In view of this, we propose a large-scale titanium sponge reactor rapid furnace cleaning equipment. Summary of the Invention

[0027] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0028] This embodiment provides a technical solution:

[0029] See also Figures 1-6A large-scale titanium sponge reactor rapid furnace cleaning device includes a reactor 1, a discharge port 11 is provided at the bottom end of the reactor 1; a furnace cleaning portion 2 is provided in the opening of the reactor 1. The furnace cleaning portion 2 is used to clean the inside of the reactor 1; it includes a hollow truncated cone 20, two argon interfaces 201 are installed on the top surface of the truncated cone 20, and a plurality of argon nozzles 202 are installed on the circumferential outer wall of the truncated cone 20; a first transmission shaft 22 is rotatably installed on the bottom surface of the truncated cone 20, a motor 21 for driving the first transmission shaft 22 to rotate is installed on the top surface of the truncated cone 20, a second transmission shaft 24 is installed below the first transmission shaft 22, and a differential 23 is provided at the connection between the first transmission shaft 22 and the second transmission shaft 24. The differential 23 is provided to facilitate faster rotation of the second transmission shaft 24, which is convenient for Drive the scraper 29 to move quickly to better clean the reactor 1; multiple first turntables 25 are coaxially fixed on the first transmission shaft 22, and the first transmission shaft 22 is coaxially keyed to the first turntable 25, and a second turntable 26 is coaxially fixed on the second transmission shaft 24, and the second turntable 26 is coaxially keyed to the second transmission shaft 24, and multiple joints 27 are installed on the outer walls of the first turntable 25 and the second turntable 26, and a brush 28 for cleaning the inner wall of the reactor 1 is installed at the end of the joint 27 located at the top, and a scraper 29 for cleaning the inner wall of the reactor 1 is installed at the end of the joint 27 located at the bottom.

[0030] Through the above-mentioned setting, the motor 21 drives the first transmission shaft 22 and the second transmission shaft 24 to rotate. Under the action of centrifugal force, the brush 28 and the scraper 29 can directly act on the inner wall of the reactor 1. The climbing titanium attached to the inner wall of the reactor 1 is dropped out of the reactor 1 by the scraper, and fine impurities such as magnesium chloride are brushed off by the brush 28, and then argon is sprayed out of the argon nozzle 202 above the equipment to blow the impurities out of the reactor 1.

[0031] Furthermore, the joint 27 includes a fixing rod 271, which is tightly welded to the first turntable 25 and the second turntable 26. A first ear plate 2711 is installed on the fixing rod 271, and the fixing rod 271 is tightly welded to the first ear plate 2711. A connecting seat 272 is installed at the end of the fixing rod 271, and a connecting block 274 is hinged in the opening of the connecting seat 272. A rocker arm 273 is fixed on the connecting block 274, and the rocker arm 273 is tightly welded to the connecting block 274. A second ear plate 2731 is installed on the rocker arm 273, and the rocker arm 273 is tightly welded to the second ear plate 2731. A hook spring 275 is hung between the first ear plate 2711 and the second ear plate 2731.

[0032] Through the above-mentioned arrangement, under the action of the hook spring 275, a force is applied to the swing rod 273, causing the swing rod 273 to bend inward. When the furnace cleaning part 2 is placed into the opening of the reactor 1, the arrangement of the brush 28 and the scraper 29 will not hinder the lifting of the furnace cleaning part 2, and it is convenient to place the furnace cleaning part 2 into the reactor 1; when the first transmission shaft 22 and the second transmission shaft 24 rotate, the first turntable 25 and the second turntable 26 rotate synchronously. At this time, centrifugal force will be generated on the swing rod 273 under high-speed rotation. When the centrifugal force is greater than the elastic force of the hook spring 275, the hook spring 275 is stretched, and the swing rod 273 is stretched at this time, and the brush 28 and the scraper 29 are driven to fit the inner wall of the reactor 1, so that the inner wall of the reactor 1 can be cleaned.

[0033] In this embodiment, the overall shape of the scraper 29 is arc-shaped, and the scraper 29 is fixedly connected to the end of the rocker 273 by bolts. This design facilitates the effective cleaning of the inner wall of the reactor 1 through the movement of the scraper 29.

[0034] In this embodiment, the top surface of the cone 20 is equipped with a plurality of lifting ears 203 distributed in a circular shape with equal intervals, and the number of the lifting ears 203 is 3-5, and the preferred number of the lifting ears 203 is 4. The arrangement of the lifting ears 203 facilitates the installation of the lifting rope and facilitates the lifting of the furnace cleaning part 2 into the reactor 1 by a crane.

[0035] In this embodiment, multiple argon nozzles 202 are distributed in a circular shape with equal intervals, and the number of argon nozzles 202 is 7-9, and the preferred number of argon nozzles 202 is 8. The arrangement of multiple argon nozzles 202 facilitates blowing out argon to blow impurities out of the reactor 1.

[0036] In this embodiment, the brush 28 is fixedly connected to the end of the rocker arm 273 by a bolt, and the brush 28 is a wire brush. The wire brush has the advantages of good cleaning effect and wear resistance, and can better clean the inner wall of the reactor 1.

[0037] In this embodiment, the argon interface 201, the frustum 20 and the multiple argon nozzles 202 are an integrally formed structure, and the argon interface 201, the frustum 20 and the multiple argon nozzles 202 are sequentially connected. This design facilitates blowing out argon to purge impurities out of the reactor 1.

[0038] In this embodiment, a limiting member 2721 is installed in the opening of the connecting seat 272, and the limiting member 2721 is pressed against the connecting block 274. The setting of the limiting member 2721 limits the swing rod 273 to prevent the swing rod 273 from being excessively bent.

[0039] It is worth noting that the motor 21 and the differential 23 in this embodiment are conventional technologies and will not be described in detail here.

[0040] During specific use, the user first fixes the lifting rope on the lifting ear 203, and fixes the furnace cleaning part 2 on the crane through the lifting rope. At this time, the crane lifts the furnace cleaning part 2 and aligns the bottom end of the furnace cleaning part 2 with the opening of the reactor 1. At the same time, the user turns on the power of the motor 21, and the motor 21 starts to work. The output shaft of the motor 21 rotates to drive the first transmission shaft 22 to rotate. Under the action of the differential 23, the second transmission shaft 24 is synchronized. At this time, the first turntable 25 and the second turntable 26 rotate synchronously. At the same time, the crane turns The furnace cleaning part 2 is slowly lowered. As the speed of the output shaft of the motor 21 increases, the multiple rocker arms 273 move outward, the hook spring 275 is stretched, and at the same time, the brush 28 and the scraper 29 contact and rub against the inner wall of the reactor 1. At this time, the tiny impurities such as the climbing titanium magnesium chloride on the inner wall of the reactor 1 are dropped by the scraper. At the same time, argon gas enters the truncated table 20 through the argon interface 201 and is ejected through the multiple argon nozzles 202. At this time, the argon gas blows downward and sweeps the impurities to the outside through the discharge port 11.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention.
