Description

Technical Field

[0001] The present application relates to the technical field of flotation beneficiation equipment, and in particular to a flotation scraper cleaning device. Background Art

[0002] In flotation beneficiation, after the ore pulp is treated with a suitable reagent and air is introduced into the ore pulp, the bubbles come into contact with the target mineral under the action of stirring and selectively adhere to it, so that the particles of the target mineral follow the bubbles and float to the upper part of the liquid surface and form foam, and the foam is scraped out of the flotation tank by the scraper to achieve the purpose of beneficiation. The scraper is easy to be sticky with mineral particles, which increases the load of the equipment and reduces the efficiency of scraping foam. For this reason, some scraper cleaning devices have been designed. For example, the Chinese patent with application number 202223155511.X discloses a flotation machine scraper cleaning device, including: a flotation machine housing, with brackets on the left and right sides of the top of the front end, and a scraper hollow shaft is rotatably connected between the two brackets; a flotation machine scraper unit, including a fixing sleeve, fixing screws, a connecting assembly and a scraper. The device achieves the purpose of cleaning the scraper by setting an electric push rod on the flotation machine scraper and using the electric push rod to drive the U-shaped scraper bar to reciprocate. However, in actual use, the electric push rod continues to expand and contract after being attached to foam, which can easily bring liquid into the machine body, causing problems such as rust and short circuit. Secondly, the electric push rod is powered by rotating conductive components, and the power supply components are in contact through rotation. Friction parts need to be replaced regularly to ensure good current transmission, which increases equipment maintenance costs and reduces equipment startup rate. Utility Model Content

[0017] It should be noted that all directional indications in the embodiments of the present application (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0018] In addition, the descriptions of "first", "second", etc. in this application are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0019] like Figures 1 to 3 As shown, an embodiment of the utility model provides a flotation scraper cleaning device, comprising: a rotating shaft 1, a flotation scraper 2, a scraper cleaning assembly 3, and a flotation casing 4, wherein the rotating shaft 1 is a hollow tubular structure, and both ends of the rotating shaft 1 are connected to the flotation casing 4 through bearings; the flotation scraper 2 is installed on the rotating shaft 1 through a first bracket 5, and the long direction of the flotation scraper 2 is parallel to the axis of the rotating shaft 1; the scraper cleaning assembly 3 is slidably installed on the flotation scraper 2; a pull rod 6 is provided in the rotating shaft 1, and the pull rod 6 is slidably connected to the inner wall of the rotating shaft 1, and the pull rod 6 is connected to the scraper cleaning assembly 3 through a connecting rod 7.

[0020] During flotation, the ore pulp treated with a suitable reagent is added to the flotation housing 4, and air is introduced into the ore pulp. Under the stirring action, the bubbles contact with the target mineral particles and selectively adhere to them, so that the target mineral particles follow the bubbles and float to the upper part of the liquid surface and form foam. The driving motor 10 drives the rotating shaft 1 to rotate through the belt, so that the flotation scraper 2 makes a circular motion, thereby pushing the upper foam of the flotation housing 4 to move toward the outlet of the flotation housing 4. When the flotation scraper 2 scrapes the foam, the mineral particles will adhere to the side of the flotation scraper 2. At this time, the connecting plate 9 is driven to reciprocate by the electric push rod 8. Since one end of the pull rod 6 is stuck on the connecting plate 9, the pull rod 6 can rotate around the connecting plate 9. When the connecting plate 9 reciprocates along the axis, it will drive the pull rod 6 to move synchronously. When the pull rod 6 moves axially, it will drive the scraper cleaning assembly 3 to move together. The bristles on the scraper cleaning assembly 3 are used to clean both sides of the flotation scraper 2 to prevent a large amount of mineral particles and foam from gathering on the side of the flotation scraper 2, thereby reducing the load of the driving motor 10. The electric push rod 8 is arranged on the side of the flotation machine housing 4 and is not easy to contact with the slurry, which can prevent the electric push rod 8 from rusting or short-circuiting, thereby improving the reliability of the equipment.

[0021] Preferably, the scraper cleaning assembly 3 includes a second bracket 31 and a roller 32. The second bracket 31 is U-shaped. The flotation scraper 2 passes through the second bracket 31, and the second bracket 31 is slidingly connected to both sides of the flotation scraper 2 in the long direction through the roller 32. The second bracket 31 is installed with bristles, and the bristles are used to clean both sides of the flotation scraper 2. The roller 3 can reduce the friction so that the scraper cleaning assembly 3 can slide smoothly on the flotation scraper 2. The second bracket 31 is arranged on both sides of the flotation scraper 2. The second bracket 31 can reciprocate under the drive of the connecting rod 7, so as to clean the flotation scraper 2 and keep the flotation scraper 2 clean.

[0022] Preferably, both sides of the flotation scraper 2 in the long direction are provided with slots, and the outer circumference of the roller 32 is adapted to the slots, so that the roller 32 can be kept on the flotation scraper 2 and move along the flotation scraper 2 .

[0023] Specifically, a long groove 11 is provided on the rotating shaft 1, one end of the connecting rod 7 is connected to the pull rod 6, and the other end of the connecting rod 7 is connected to the second bracket 31 after passing through the long groove 11. A support plate 12 is provided in the rotating shaft 1, and the pull rod 6 passes through the support plate 12, and the pull rod 6 is slidably connected to the support plate 12, so that the pull rod 6 can slide smoothly in the rotating shaft 1, thereby realizing power transmission to the electric push rod 8.

[0024] Preferably, two electric push rods 8 are provided on one side of the flotation housing 4, and the electric push rods 8 are respectively arranged on both sides of the pull rod 6, and the telescopic ends of the electric push rods 8 are connected to each other through the connecting plate 9. When cleaning the flotation scraper 2, the two electric push rods 8 are synchronously extended and retracted to drive the connecting plate 9 to move. One end of the pull rod 6 is stuck on the connecting plate 9, so that the pull rod 6 can rotate circumferentially in the connecting plate 9. After the electric push rod 8 is extended and retracted, the pull rod 6 can be driven to move axially through the connecting plate 9, thereby driving the scraper cleaning assembly 3 to move through the pull rod 6 to achieve cleaning of the flotation scraper 2.

[0025] Preferably, a driving motor 10 is installed outside the flotation housing 4, and the driving motor 10 is connected to one side of the rotating shaft 1 through a belt. The driving motor 10 provides power to rotate the flotation scraper 2 to scrape the foam on the upper layer of the slurry.

[0026] Of course, the present application may have many other implementations. Based on the present implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present application.
