Description

Technical Field

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

[0002] Flotation machines are key equipment in the mineral processing field, with a wide range of applications. They are not only suitable for the separation of non-ferrous metals such as copper, zinc, lead, nickel, and gold, but also for roughing and cleaning of ferrous metals and non-metals. During operation, the motor drives the impeller to rotate at high speed through a V-belt drive, creating a negative pressure environment using centrifugal force. This negative pressure environment plays a dual role: first, it draws in sufficient air to fully mix with the pulp, providing the necessary oxygen conditions for the flotation process; second, it strongly agitates the pulp, promoting uniform mixing of the pulp and flotation reagents, enhancing the selectivity of the reagents for minerals. At the same time, the agitation of the impeller also refines the foam, allowing mineral particles to effectively adhere to the foam surface. As the foam rises to the surface of the pulp, it forms a mineralized foam layer rich in the target minerals. Finally, the useful foam is scraped off by the scraper, achieving the separation of the target minerals from the gangue minerals.

[0003] A search revealed that Chinese patent CN221157157U discloses a scraping device for a flotation machine, comprising a flotation cell, a support rod, and a scraper. The scraper is fixedly installed on the surface of the support rod. The top of the flotation cell is connected to a support column that can move back and forth. A rotating column is rotatably connected to the surface of the support column. A snap-fit ​​assembly is provided on the surface of the support column. Disassembling the support rod facilitates the replacement of the support rod and the scraper. The lack of support on one side during disassembly of the above-mentioned technology makes the scraper plate prone to falling off, which may injure the operator's feet or other parts of the body, causing work-related accidents, affecting the health and work efficiency of employees. The falling scraper plate may also hit other parts of the scraping device, causing these parts to deform and be damaged, increasing equipment maintenance costs and the cost of replacing parts. Because disassembly is troublesome, more time and effort are required to complete the disassembly operation, which will prolong the downtime of the equipment. Utility Model Content

[0021] 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.

[0022] Example 1 Please see Figure 1 - Figure 3 This utility model provides a technical solution: a scraping device, including a flotation cell 1 and a scraping plate 2 located on the upper side of the flotation cell 1. A fixing clamping mechanism 3 is provided on the outer side of both ends of the flotation cell 1. The fixing clamping mechanism 3 is used to quickly clamp and disassemble the scraping plate 2.

[0023] The fixed clamping mechanism 3 in this embodiment includes a mounting base 301, which is fixedly connected to the outer sides of both ends of the flotation cell 1. A clamping slider 302 is slidably connected to the inner side of the top of the mounting base 301. A claw assembly 5 is provided on the upper side of the clamping slider 302. A connecting plate 303 is slidably connected to the inner side of the middle part of the clamping slider 302. A threaded rod 304 is rotatably connected to the lower surface of the middle part of the connecting plate 303. The outer side of the threaded rod 304 is threadedly connected to the inner side of the bottom end of the mounting base 301. Trapezoidal protrusions are provided on the outer sides of both ends of the connecting plate 303. A trapezoidal through groove is provided on the inner side of one end of the clamping slider 302. The trapezoidal protrusion of the connecting plate 303 is located inside the trapezoidal through groove of the clamping slider 302.

[0024] The clamping slider 302 is disposed on the upper side of the mounting base 301, and a guide post 306 is provided between the connecting plate 303 and the mounting base 301. The guide post 306 is fixedly connected to the lower surface of the connecting plate 303, and the outer side of the guide post 306 is slidably connected to the inner side of the mounting base 301.

[0025] A spring 305 is also provided between the connecting plate 303 and the mounting base 301, and the spring 305 is sleeved on the outside of the threaded rod 304. A top block 307 with an upward protrusion is provided in the middle of the connecting plate 303. The upper surface of the top block 307 is arc-shaped, which can prevent the scraper plate 2 from falling off accidentally, ensuring safety.

[0026] The claw assembly 5 includes a gripper 501 and a ball bearing 502. The gripper 501 is fixedly connected to the upper side of the gripping slider 302, and the ball bearing 502 is rotatably connected to the inner side of the arc-shaped structure of the gripper 501. The outer side of the ball bearing 502 is in contact with the outer sides of both ends of the scraper plate 2.

[0027] In this embodiment, the two ends of the scraper plate 2 are placed inside the claw assembly 5. When the scraper plate 2 needs to be installed quickly, the threaded rod 304 is rotated to drive the connecting plate 303 to descend vertically. When the connecting plate 303 descends vertically, the dovetail blocks on the outer sides of its two ends and the dovetail grooves 311 on the inner side of the clamping slider 302 can pull the two clamping sliders 302 to move towards the center. Through the storage of elastic potential energy of the spring 305, additional support force can be provided when the threaded rod 304 is rotated in the opposite direction. At the same time, the two guide posts 306 can limit the movement trajectory of the connecting plate 303 to ensure that the connecting plate 303 moves in the vertical direction. The arc-shaped structure on one side of the top block 307 can temporarily support the outer sides of the two ends of the scraper plate 2. As the two claws 501 continue to clamp towards the center, the rolling ball 502 can be pressed against the outer side of the end of the scraper plate 2, which facilitates the rotation of the scraper plate 2 to scrape the material, reduces the friction on the scraper plate 2, and realizes the quick disassembly and limiting of the scraper plate 2.

A connecting plate 303 is provided on the inner side of the mounting base 301. Elongated holes are provided on the outer sides of both ends of the rotating arm 308. A first protrusion 309 is provided on the outer sides of both ends of the connecting plate 303. A second protrusion 310 is provided on the side of the clamping slider 302. The two ends of the rotating arm 308 are respectively connected to the first protrusion 309 and the second protrusion 310 through the elongated holes.

[0029] The upper part of the threaded rod 405 is rotatably connected to the mounting base 301, and the lower end is threadedly connected to the middle of the connecting plate 303. When the threaded rod 304 is rotated, it will cause the connecting plate 303 to descend vertically. When the connecting plate 303 descends vertically, the first protrusion 309 on the outer side of the end of the connecting plate 303 can push the rotating arm 308 to rotate. At the same time, through the through groove opened at the other end of the rotating arm 308 and the second protrusion 310 of the clamping slider 404, the rotating arm 308 and the clamping slider 404 are driven to clamp towards the center, which can drive the two grippers 501 to clamp towards the center.
