DETAILED DESCRIPTION

[0015] The utility model is further described below in conjunction with the accompanying drawings:

[0016] like Figure 1-2 As shown, a "micro-gravity" precious metal beneficiation machine using a felt gold method comprises a main frame 1, a belt conveyor frame 4 is provided in the middle of the main frame 1, an angle adjustment device 2 is provided between the main frame 1 and the belt conveyor frame 4, a redirecting roller 6 and a driving roller 7 are provided on the belt conveyor frame 4, an annular felt 5 is provided on the redirecting roller 6 and the driving roller 7, a roller 9 is provided at the bottom of the annular felt 5, the driving roller 7 is connected to the transmission mechanism 8 through a coupling, the roller 9 is used for supporting and guiding the annular felt 5, and a material collecting trough 10 is provided below the belt conveyor frame 4.

[0017] The main frame 1 is a metal frame, which is installed on a pre-made installation platform and fixed by bolts to ensure that the equipment has good stability during operation.

[0018] There are four angle adjustment devices 2, one end of which is mounted at the four top corners of the main frame 1, and the other end is mounted at the four top corners of the belt conveyor frame 4. The angle adjustment device 2 includes a lead screw 21, the bottom end of which is fixedly connected to a connecting rod 22, and the bottom end of the connecting rod 22 is connected to the belt conveyor frame 4 through a hinge. The main frame 1 is fixed with a plate, and a nut 23 at the top of the lead screw is arranged on the upper part of the fixed plate 24. The inclination angle of the belt conveyor can be adjusted by adjusting the nut 23 at the top of the lead screw.

[0019] A slide 11 is provided on the belt conveyor frame 4, and the bearing seat of the redirecting roller 6 is arranged on the slide 11, and the slide 11 is connected to the tensioning device 3. The tensioning device 3 is a screw nut pair, and the end of the screw of the screw nut pair is connected to the slide 11. By adjusting the screw nut 12 at the front end of the screw nut pair to move the slide 11, the tension of the annular felt 5 can be adjusted.

[0020] The transmission mechanism 8 is composed of a motor and a reducer. The motor is a variable frequency motor, and the belt speed of the belt conveyor can be controlled by adjusting the motor operating frequency to adapt to different production loads.

[0021] The material collecting trough 10 is fixed under the belt conveyor frame. When the concentrate product adsorbed on the annular felt 5 falls, it can be collected. The front baffle of the material collecting trough can be flexibly disassembled, and it is convenient to clean up when the material is full.

[0022] The transmission mechanism 8 is designed and installed with a remote control system and an interlocking control system, which can realize both remote and local control modes and realize unmanned operation. The interlocking control system can start or stop in coordination with upstream and downstream equipment, thereby improving the operating efficiency of the equipment and avoiding accidents such as mine leakage caused by failure of a single device, further improving the safety of the equipment.

[0023] When in use, the transmission mechanism 8 is opened to drive the annular felt 5 to move. The mineral moves on the annular felt 5 in the form of slurry. The precious metals in the slurry will settle downward and adhere to the annular felt 5 due to the effect of micro-gravity. When the annular felt 5 with the precious metals attached rotates to the bottom, the precious metals adsorbed on the annular felt 5 fall into the collecting tank 10. The precious metal concentrate can be collected in the material collecting tank, thereby realizing the separation of the precious metal concentrate in the mineral.

[0024] The utility model is a felt gold method "micro-gravity" precious metal beneficiation machine which is simple and practical, has low manufacturing cost and long service life, and is combined with the actual situation on site, with particular emphasis on practicality and maintainability.
