Description

Technical fields:

[0001] This utility model relates to the field of mineral processing technology, specifically to a scraper cleaning mechanism for a flotation machine. Background technology:

[0002] In mining engineering, flotation machines are often used to float mineral slurries. During the process of scraping the foam with a scraper, the scraper is in contact with the slurry for a long time, and the slurry will adhere to the scraper surface. This slurry will solidify on the scraper surface and form scale, thereby increasing the overall weight of the scraper. A scraper cleaning mechanism is needed to clean the surface of the scraper.

[0003] The existing scraper cleaning mechanism mainly consists of multiple scraper rods sliding on the scraper plate. The motor drive transmission shaft of the flotation machine 1 drives the scraper plate to rotate through the connecting rod. The scraper plate drives the scraper rods on it to rotate synchronously. The drive component drives the scraper rods to slide back and forth on the scraper plate to clean its surface. The synchronous rotation of the scraper rods with the scraper plate will cause the scraper rods to be immersed in the slurry containing the reagents. The scraper rods are prone to corrosion, which leads to a reduction in the service life of the scraper rods. Utility model content:

[0004] Therefore, the purpose of this utility model is to provide a scraper cleaning mechanism for a flotation machine to overcome the problems of the prior art. The existing scraper cleaning mechanism mainly consists of multiple scraper rods sliding on a scraper plate. The motor drive transmission shaft of the flotation machine 1 drives the scraper plate to rotate through the connecting rod. The scraper plate drives the scraper rods on it to rotate synchronously. The drive assembly drives the scraper rods to slide back and forth on the scraper plate to clean its surface. The synchronous rotation of the scraper rods with the scraper plate will cause the scraper rods to be immersed in the slurry containing the reagents, which will easily cause corrosion of the scraper rods and reduce their service life.

[0005] This utility model is implemented by the following technical solution:

[0006] A scraper cleaning mechanism for a flotation machine includes a flotation machine. A drive shaft of the flotation machine is uniformly and fixedly connected to multiple scrapers via connecting rods. A transmission assembly is fixedly connected to the inner wall of the flotation machine. The input end of the transmission assembly is fixedly connected to the drive shaft of the flotation machine, and the output end of the transmission assembly is fixedly connected to a reset assembly. A scraper rod is fixedly connected to the bottom surface of the reset assembly. The rotating drive shaft of the flotation machine drives the transmission assembly to drive the scraper rod to intermittently be sleeved on the top scraper and slide on it via the reset assembly.

[0007] Preferably, the cross-section of the scraper is inverted U-shaped, and the wall thickness of the two vertical rods facing each other decreases from the center to the two sides of the component.

[0008] Preferably, the minimum distance between the two vertical bars of the scraper is equal to the wall thickness of the scraper.

[0009] Preferably, the transmission assembly includes a bearing fixedly embedded in the inner wall of the flotation machine, a reciprocating screw fixedly connected to the inner ring of the bearing, a slider slidably disposed in the groove of the reciprocating screw, a limiting rod slidably disposed on the reciprocating screw, the top surface of the limiting rod being a plane and slidingly connected to the inner top surface of the flotation machine, the inner top surface of the limiting rod being fixedly connected to the top surface of the slider, one end of the reciprocating screw passing through the flotation machine and rotatably connected thereto, and two pulleys connected by belt drive on the outside of the flotation machine, one pulley being fixedly sleeved on the reciprocating screw, and the other pulley being fixedly sleeved on the drive shaft of the flotation machine.

[0010] Preferably, the reset assembly includes an arc-shaped slide rail fixed to the bottom end of the limiting rod. The inner arc surface of the arc-shaped slide rail has a dovetail groove. A dovetail block is slidably disposed in the dovetail groove. A compression spring is fixedly connected between the dovetail block and the arc-shaped slide rail. The compression spring is disposed in the dovetail groove. The bottom surface of the dovetail block is fixedly connected to the top surface of the scraper rod.

[0011] Preferably, the inner wall of the flotation machine is fixedly connected with two positioning grooves, and the scraper is disposed between the two positioning grooves. The cross-sectional shape of the facing surfaces of the two positioning grooves is a U-shape with the opening gradually increasing.

[0012] Preferably, the shortest distance between the two opposing vertical plates of the positioning groove is equal to the distance between the opposing surfaces of the two vertical rods of the scraper.

[0013] The advantages of this invention are as follows: A transmission assembly is fixedly connected to the inner wall of the flotation machine. The rotating flotation machine transmission shaft drives the transmission assembly to drive the scraper rod to intermittently fit onto the top scraper plate and slide on it to clean the slag on the surface of the scraper plate. This eliminates the need for the scraper plate to rotate and immerse the scraper rod in the slurry, thus reducing the contact between the scraper rod and the slurry in the flotation machine, thereby reducing the corrosion of the scraper rod by the reagent-containing slurry and extending the service life of the scraper rod.

[0020] To make the objectives and advantages of this utility model clearer, the utility model will be further described below with reference to the embodiments; it should be understood that the specific embodiments described herein are only for explaining this utility model and are not intended to limit this utility model.

[0021] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0022] It should be noted that in the description of this utility model, the terms "upper", "lower", "left", "right", "inner", "outer", etc., indicating the direction or positional relationship are based on the direction or positional relationship shown in the drawings. This is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0023] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] like Figures 1-4 As shown, this utility model provides the following technical solution: a flotation machine scraper cleaning mechanism, including a flotation machine 1, a plurality of scrapers 2 are uniformly fixedly connected to the drive shaft of the flotation machine 1 through connecting rods, a transmission component is fixedly connected to the inner side wall of the flotation machine 1, the input end of the transmission component is fixedly connected to the drive shaft of the flotation machine 1, and a reset component is fixedly connected to the output end of the transmission component. A scraper rod 12 is fixedly connected to the bottom surface of the reset component. The rotating drive shaft of the flotation machine 1 drives the transmission component to drive the scraper rod 12 to intermittently be sleeved on the top scraper 2 and slide on it through the reset component.

[0025] Please combine Figure 1 As shown, when the motor of the flotation machine 1 drives the transmission shaft to rotate multiple scrapers 2 through the connecting rod to scrape the material, the transmission shaft of the flotation machine 1 drives the transmission component to work. The transmission component drives the reset component to make a lateral amplitude movement. The reset component drives the scraper rod 12 to gradually fit onto the top scraper 2 and slide on its surface to clean it. The scraper rod 12 is fitted onto one end of the scraper 2 and gradually slides off from the other end of the scraper 2 to clean the slag adhering to the surface of the scraper 2. The scraper 2 drives the scraper rod 12 fitted on its surface to rotate at a small angle. The scraper rod 12 drives the reset component to rotate at a small angle. When the scraper rod 12 is separated from the scraper 2, the reset component drives the scraper rod 12 to rotate and reset so that it can be fitted onto another scraper 2 that is about to rotate to the top.

[0026] The cross-section of the scraper 12 is an inverted U-shape. The wall thickness of the two vertical rods of the scraper 12 decreases from the center to the sides, increasing the coverage area at one end of the scraper 2 and making it easier for the scraper 12 to slide onto the scraper 2.

[0027] The minimum distance between the two vertical bars of the scraper 12 is equal to the wall thickness of the scraper 2, which can completely clean the slag on the surface of the scraper 2, improve the cleanliness of the scraper 2 surface, and reduce the load on the scraper 2.

[0028] Please combine Figure 1 , Figure 2 , Figure 3 As shown in the embodiment of the transmission assembly, the transmission assembly includes a bearing 4 fixedly embedded in the inner wall of the flotation machine 1. A reciprocating screw 3 is fixedly connected to the inner ring of the bearing 4. A slider 5 is slidably provided in the groove of the reciprocating screw 3. A limiting rod 6 is slidably provided on the reciprocating screw 3. The top surface of the limiting rod 6 is flat and slidably connected to the inner top surface of the flotation machine 1. The inner top surface of the limiting rod 6 is fixedly connected to the top surface of the slider 5. One end of the reciprocating screw 3 passes through the flotation machine 1 and is rotatably connected to it. Two pulleys 7 connected by belt drive are provided on the outside of the flotation machine 1. One pulley 7 is fixedly sleeved on the reciprocating screw 3, and the other pulley 7 is fixedly sleeved on the drive shaft of the flotation machine 1.

[0029] Please combine Figure 1 As shown, during operation, the drive shaft of the flotation machine 1 drives the pulley 7 fixed to it to rotate. The pulley 7 drives another pulley 7 to rotate via a belt. The other pulley 7 drives the reciprocating screw 3 to rotate. The reciprocating screw 3 drives the slider 5 in its groove to move laterally. The slider 5 drives the limit rod 6 to move. The limit rod 6 drives the reset assembly to move laterally. The reset assembly drives the scraper 12 to move laterally.

[0030] Please combine Figure 1 , Figure 2 , Figure 3 As shown in the embodiment of the reset assembly, the reset assembly includes an arc-shaped slide rail 8 fixed to the bottom end of the limiting rod 6. The inner arc surface of the arc-shaped slide rail 8 has a dovetail groove 9. A dovetail block 10 is slidably arranged in the dovetail groove 9. A compression spring 11 is fixedly connected between the dovetail block 10 and the arc-shaped slide rail 8. The compression spring 11 is arranged in the dovetail groove 9. The bottom surface of the dovetail block 10 is fixedly connected to the top surface of the scraper rod 12.

[0031] Please combine Figure 1 As shown, during use, the sliding limit rod 6 drives the arc-shaped slide rail 8 to move, the arc-shaped slide rail 8 drives the dovetail groove 9 to move, the dovetail groove 9 drives the dovetail block 10 to move, and the dovetail block 10 drives the scraper rod 12 to move. The scraper rod 12, which is sleeved on the top scraper plate 2, is driven by the scraper plate 2 to rotate at a small angle. The scraper rod 12 drives the dovetail block 10 to slide in the dovetail groove 9 and compress the compression spring 11 to deform. When the scraper rod 12 separates from the scraper plate 2, the deformed compression spring 11 pushes the dovetail block 10 to move and reset. The dovetail block 10 drives the scraper rod 12 to rotate and reset, so that the scraper rod 12 can be sleeved on the top scraper plate 2 again.

[0032] Two positioning grooves 13 are fixedly connected to the inner wall of the flotation machine 1. The scraper 12 is disposed between the two positioning grooves 13. The cross-sectional shape of the facing surfaces of the two positioning grooves 13 is a U-shape with the opening gradually increasing.

[0033] Please combine Figure 1 As shown, during use, when the scraper 12 gradually slides off the scraper 2, the compression spring 11 pushes the dovetail block 10 to move and reset. The dovetail block 10 drives the scraper 12 to rotate and reset. When the compression spring 11 indirectly pushes the scraper 12 to rotate and reset, it will cause the scraper 12 to vibrate slightly. The drive shaft of the flotation machine 1 indirectly drives the scraper 12 to move with amplitude and gradually slide into the positioning grooves 13 on both sides. The positioning grooves 13 limit the scraper 12 that is vibrating slightly, reduce the slight vibration of the scraper 12, and improve the stability of the scraper 12.

[0034] The shortest distance between the two opposing vertical plates of the positioning groove 13 is equal to the distance between the opposing surfaces of the two vertical rods of the scraper 12, thereby limiting the scraper 12 and improving the stability of the scraper 12 when it slides.

[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
