Description

Technical Field

[0001] The utility model is applicable to the technical field of copper smelting flotation machines, in particular to a froth scraper for a flotation machine. Background Art

[0002] At present, flotation machine is the abbreviation of flotation concentrator, which refers to the mechanical equipment that completes the flotation process. In the flotation machine, the slurry treated with reagents is stirred and aerated so that some of the mineral particles are selectively fixed on the bubbles, float to the surface of the slurry and are scraped out to form foam products, while the rest are retained in the slurry, and then the foam is scraped out by a scraper to achieve the purpose of separating minerals.

[0003] However, when removing the foam accumulated on the surface of the flotation machine, a rotatable scraper is often set on one side of the pool body, and the bubbles floating on the liquid surface are scraped off by repeated rotation of the scraper. In this process, the foam floating on the entire pool surface cannot be quickly scraped off, which easily increases the time required for the overall scraping and affects the efficiency of copper ore processing. Therefore, we propose a flotation scraper for a flotation machine. Utility Model Content

[0004] The main purpose of the utility model is to provide a froth scraper for a flotation machine, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A froth scraper for a flotation machine comprises a flotation tank body, both sides of the top of the flotation tank body are fixedly mounted with hollow frames, and a fixed frame is slidably mounted between the tops of two groups of the hollow frames;

[0007] A rotating screw is rotatably mounted on the middle end of the inner side of each hollow frame through a bearing, a transmission sleeve is movably sleeved on the outer side surface of each rotating screw, a connecting frame is fixedly mounted on the outer top surface of each transmission sleeve, and the top surface of the connecting frame is fixedly connected to the bottom surface of the fixed frame, and a foam scraper is fixedly mounted on the inner bottom surface of the fixed frame;

[0008] Both ends of the top of the side of the scraper plate are fixedly installed with delivery pipes, the bottom surface of each delivery pipe is fixedly connected with an extraction pipe, and the number of extraction pipes is several groups, and the bottom surface of each extraction pipe is fixedly connected with an extraction head.

[0009] By adopting the above technical scheme, the foam floating on the entire surface of the flotation tank body is scraped and gathered under the rotational transmission action of the rotating screw on the transmission sleeve and the communication action of the extraction pipe and the extraction head, while the foam gathered on the surface of the scraper plate is scraped and quickly extracted and transported to the inside of the waste storage frame, thereby further improving the scraping speed of the floating foam on the surface of the flotation tank body and avoiding excessive accumulation of foam during the scraping process to affect the normal movement of the scraper plate.

[0010] As an optional solution of the technical solution of the present application, a servo motor is fixedly installed on the outer surface of each hollow frame, and the side of the servo motor transmission shaft is fixedly connected to the outer top surface of the rotating screw through a coupling.

[0011] By adopting the above technical solution, the driving force required for the rotation of the screw rod can be provided through the structural function of the servo motor.

[0012] As an optional solution of the technical solution of the present application, each of the conveying pipes is fixedly connected with connecting pipes on both sides of the top, a waste storage frame is fixedly installed on the outer surface of the top of each fixed frame, and the top of the connecting pipe and the bottom of the waste storage frame are fixedly connected, each of the outer end surfaces of the waste storage frame is fixedly connected with a waste discharge pipe, and an extraction pump is fixedly installed on the outer surface of each connecting pipe.

[0013] By adopting the above technical solution, the waste storage frame is provided to ensure that the extracted foam can be collected and stored, thereby preventing the foam from flowing arbitrarily and affecting subsequent processing thereof.

[0014] As an optional solution of the technical solution of the present application, a limiting groove is provided on the top of each hollow frame, and the connecting frame is slidably installed inside the limiting groove.

[0015] By adopting the above technical solution, the rationality of the transmission adjustment of the entire device is ensured by the guiding and limiting effect of the limiting groove on the connecting frame.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1. The technical solution of the present application is a froth scraper for a flotation machine. A rotating screw is arranged on the side of a flotation tank body, and a transmission sleeve is sleeved on the outer side of the rotating screw, so that the rotating screw can drive the transmission sleeve and the fixed frame to move horizontally synchronously when rotating. In addition, a scraper plate is arranged on the inner side of the fixed frame, so that when the fixed frame moves horizontally on the surface of the flotation tank body, the scraper plate below the fixed frame is synchronously driven to move horizontally inside the flotation tank body, so that the floating foam inside the flotation tank body is scraped and gathered, and the subsequent flotation efficiency of the copper ore is improved.

[0018] 2. The technical solution of the present application is a scraper for a flotation machine. By arranging a conveying pipe, an extraction pipe and an extraction head on the surface of the scraper plate, and combining with the operation of an extraction pump arranged on the outer side of the connecting pipe, the scraper plate can scrape and gather foam and quickly extract it to the inside of the waste storage frame, thereby further improving the scraping speed of the floating foam on the surface of the flotation tank body and avoiding excessive accumulation of foam during the scraping process to affect the normal movement of the scraper plate.
