Description

Technical Field

[0002] In the beneficiation process of gold mine powder, it is necessary to first load the collected gold ore into the vibrating feeder, and the vibrating feeder will add the gold ore into the jaw crusher in an orderly manner. The large particles processed by the jaw crusher enter the belt conveyor, and then the belt conveyor will convey the large particles to the cone crusher for processing and crushing into medium particles. The medium particles are then conveyed to the circular vibrating screen through the belt conveyor for screening (the circular vibrating screen drives the eccentric block in the vibrator to rotate and generate exciting force through the motor, so that the screen box and the screen produce approximate circular motion. The material is subjected to the combined action of centrifugal force and vibration on the screen, realizing the throwing motion and classification of the material, and achieving the purpose of screening). The small particles after screening are conveyed to the ball mill for grinding, and finally processed into gold concentrate through the classifier, spiral chute, flotation machine and dryer in sequence.

[0003] In the above process, when the gold ore particles are conveyed to the circular vibrating screen by the belt conveyor, the gold ore particles are conveyed along the conveyor belt and then fall into the discharge port, and then fall directly onto the screen in the circular vibrating screen from the discharge port.

DETAILED DESCRIPTION

[0015] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0016] Combined with Figure 1 , Attachment Figure 2 and attached Figure 3 As shown, a gold mine powder beneficiation device includes a circular vibrating screen 1 and a belt conveyor 2 used in conjunction with each other, the circular vibrating screen 1 includes a support leg 111 and a screen box 112 elastically connected to the support leg 111, a screen 113 is obliquely arranged in the screen box 112, and coaxially connected exciters 114 are symmetrically arranged at both ends of the screen box 112, and the exciter 114 is a cylindrical eccentric shaft exciter, and a material discharge port 211 is provided on the belt conveyor 2, and further includes: The pre-treatment component 3 is arranged between the discharge port 211 and the screen 113, and changes the direction of the falling particles in a diverting manner and reduces the impact force of the particles when they fall, so that the particles are divided into two independent paths and fall on both sides of the screen 113 respectively; The pre-treatment component 3 is connected to a bag dust removal component 4, and the bag dust removal component 4 is provided with a dust cleaning component 5, and the dust cleaning component 5 uses mechanical vibration to shake off the dust on the bag 410; The power switching assembly 6 is disposed between the screen box 112 and the bag dust removal assembly 4 to selectively switch the power source between the vibrator 114 and the cleaning assembly 5 .

[0017] Through the above structure, the power source is first connected to the vibrator 114 through the power switching component 6, driving the vibrator 114 to operate, and then driving the screen box 112 and the screen 113 to swing, and the belt conveyor 2 is started. The particles falling from the discharge port 211 first enter the pretreatment component 3, so that the particles change direction in a diversion manner and reduce the impact force of falling, and then fall on the two side surfaces of the screen 113, which not only avoids the strong impact on the screen 113, but also can perform diversion screening operations on the particles. In the process of falling particles, the dust inside the dust removal component 4 is processed through the bag dust removal component 4. When it is necessary to regularly clean the dust on the bag 410, the power source is first connected to the input end of the cleaning component 5 through the power switching component 6, and the dust on the bag 410 is shaken off by the cleaning component 5 using mechanical vibration, thereby improving the practicality of the device.

[0018] Combined with Figure 3 , Attachment Figure 4 , Attachment Figure 5 and attached Figure 6As shown, the pretreatment component 3 includes a treatment box 311 arranged between the discharge port 211 and the screen 113, and an upper guide plate 312 and a lower guide plate 313 in an inclined state are arranged at upper and lower positions in the treatment box 311, and the lower guide plate 313 passes through the treatment box 311 and extends to the end surface close to the screen 113, and the upper guide plate 312 and the lower guide plate 313 are arranged in opposite inclination directions, and a guide seat 315 in a triangular structure is arranged in the treatment box 311 between the upper guide plate 312 and the discharge port 211, and there is a discharge spacing between the guide seat 315 and the upper guide plate 312; A discharge port 1 316 is provided on the upper guide plate 312 corresponding to the bottom surface of the guide seat 315, a transition guide plate 1 317 is provided on the inner wall of the processing box 311, which is inclined in the opposite direction to the upper guide plate 312 and receives the particles at the discharge port 1 316, and a transition guide plate 2 318 is provided on the inner wall of the processing box 311, which is inclined in the opposite direction to the transition guide plate 1 317, and the transition guide plate 2 318 extends to the end surface close to the lower guide plate 313, and a lower guide plate 313 corresponding to the left side of the lower end of the transition guide plate 2 318 is provided with a filter corresponding to the screen 11. 3, and there is a gap in the transverse direction between the discharge port 319 and the lower end of the transition guide plate 318, so that the particles sliding down the transition guide plate 318 fall onto the lower guide plate 313 at the gap, and then slide downward along the lower guide plate 313, and the lower guide plate 313 is provided with a guide seat 322 for guiding the flow toward the discharge port 319, and the discharge port at the lower end of the lower guide plate 313 is arranged corresponding to the other side of the screen 113, and the lower guide plate 313 is provided with a guide seat 323 for guiding the flow toward the other side of the screen 113; There is a material discharge spacing between the lower end surfaces of the upper guide plate 312 and the transition guide plate 1 317 and the inner wall of the processing box 311. A top cover 314 that can penetrate into the material discharge port 211 is provided on the top surface of the processing box 311. The center position of the guide seat 315 corresponds to the center position of the material discharge port 211. A transition guide plate 320 is also provided on the bottom surface of the processing box 311 for receiving particulate matter at the discharge port 2 319.

[0019] The working principle of the pretreatment component 3 is that when the particles at the discharge port 211 fall, they first fall on the guide seat 315. Under the action of the inclined surfaces at both ends of the guide seat 315, the falling particles are diverted to the two sides of the guide seat 315. The particles on the left side pass through the upper guide plate 312, the lower guide plate 313, the discharge port 2 319 and the transition guide plate 320 and fall on one side of the screen 113 for screening. The particles on the right side pass through the upper guide plate 312, the discharge port 1 316, the transition guide plate 1 317, the transition guide plate 2 318 and the lower guide plate 31 3 falls on the other side of the screen for screening. In the process of the left and right particles sliding over and falling, the direction of the particles is changed to gradually reduce the impact force, and finally fall on the two sides of the screen 113 in a diversion manner. In order to avoid the mixing phenomenon of the particles on both sides during screening, a partition plate can be selectively added in the middle position of the screen 113, which not only avoids the phenomenon of the particles falling on the screen in a concentrated manner and prevents the falling particles from strongly impacting the screen, but also can perform a diversion screening operation on the falling particles.

Support seats 423 are provided at the four corners of the lifting seat 417 on the inner wall of the dust removal box 411. A sliding rod 424 that is slidably matched with the supporting seat 423 is fixed on the lifting seat 417, and an air inlet 418 that is connected to the bag cage is opened from bottom to top on each guide rod 415; An air intake main pipe 419 is provided on the dust removal box 411 corresponding to the vertical end of the partition 412, and a transition pipe 420 extending to the processing box 311 is provided at the other end of the air intake main pipe 419. The processing box 311 is provided with a plurality of branch pipes 421 that penetrate the transition pipe 420.

[0021] The working principle of the bag dust removal component 4 is to start the external exhaust fan, and under the action of the exhaust pipe 422, a negative pressure is formed in the dust removal box 411. At this time, through the action of the branch pipe 421, the transition pipe 420 and the air intake main pipe 419, the dust-containing gas in the treatment box 311 can be sucked into the dust removal box 411 and enter the bag 410 from the air inlet 418, so that the dust in the dust-containing gas is adsorbed on the inner surface of the bag 410, so that the dust formed in the process of pre-treatment of the particulate matter can be processed. When the dust adsorbed on the inner surface of the bag 410 is relatively large, the lifting seat 417 is controlled by the cleaning component 5 to slide up and down reciprocatingly, and at the same time, the bag cage and the bag 410 are driven to slide up and down reciprocatingly, and the dust on the inner surface of the bag 410 is shaken off.

[0023] The working principle of the cleaning component 5 is to first connect the power source to the rotating shaft 513 through the power switching component 6, and then control the rotating shaft 513 to rotate, and under the cooperation of the cam 514 and the roller 512 and the action of the reset spring 1 515 and the reset spring 2 516, the U-shaped frame 511 and the lifting seat 417 are driven to perform reciprocating up and down sliding operations.

A gear 617 used in conjunction with the gear 613 is provided on the half shaft 616 and the rotating shaft 513, and a transmission assembly 7 is provided between the half shaft 616 and the half shaft 116. An adjustment member for controlling the sliding of the adjustment cylinder 615 is provided on the dust removal box 411, and the adjustment member is an electric push rod 618, and the fixed end of the electric push rod 618 is connected to the outer wall of the dust removal box 411, and the movable end is connected to the adjustment cylinder 615; The transmission assembly 7 includes pulleys 711 respectively arranged on the half shaft 116 and the half shaft 616, and a transmission belt 712 is wound around the two pulleys 711.

[0025] The working principle of the power switching component 6 is that when the vibration exciter 114 needs to be controlled to move, the electric push rod 618 is first controlled to extend, driving the adjustment cylinder 615 and the gear 1 613 to move in the direction close to the screen box 112, so that the gear 1 613 is meshed with the gear 2 617 on the half shaft 2 616, and then the motor 611 is started to drive the spline shaft 612 and the gear 1 613 to rotate, and then drive the gear 2 617 and the half shaft 2 616 to rotate. When the half shaft 2 616 rotates, under the action of the transmission component 7, it drives the half shaft 116 to rotate, and then drives the universal transmission shaft 115 to rotate, and at the same time drives the vibration exciter 114 to move; When the dust cleaning component 5 needs to be operated, the electric push rod 618 is first controlled to retract so that its gear 1 613 is engaged with the gear 2 617 on the shaft 513, and then the motor 611 is started to drive the gear 1 613 to rotate, and then drive the gear 2 617 and the shaft 513 to rotate, and then drive the cam 514 and the roller 512 to cooperate, and finally drive the lifting seat 417 to perform a reciprocating up and down sliding operation.

[0026] When the present invention is implemented, the power transmission between the motor 611 and the vibrator 114 is first connected through the power switching component 6, the motor 611 is started, and the vibrator 114 is driven to operate. Under the action of the vibrator 114, the screen box 112 and the screen 113 are driven to vibrate, and then the belt conveyor 2 is started to convey the gold ore particles to the discharge port 211 for discharge. The discharged materials fall into the processing box 311, and the gold ore particles are diverted and changed in direction by the action of their own weight and fall in sequence, and then fall onto the two side surfaces of the screen 113 for screening. In the process of sliding, the impact force of the gold ore particles is gradually reduced, thereby avoiding the strong impact on the screen 113. As the gold ore particles continue to slide downward, a large amount of dust will be generated in the processing box 311. The dust in the processing box 311 is collected and processed by the bag dust removal component 4. When it is necessary to regularly clean the dust on the bag 410, the power transmission between the motor 611 and the rotating shaft 513 is first connected through the power switching component 6, and the motor 611 is started to drive the rotating shaft 513 to rotate, and then the cam 514 and the roller 512 are driven to cooperate, and finally the lifting seat 417 is driven to slide up and down reciprocatingly, and at the same time, the bag cage and the bag 410 are driven to slide up and down reciprocatingly, and the dust on the inner surface of the bag 410 is shaken off. The shaken dust falls from the air inlet 418 into the lower dust collecting chamber 414, thereby improving the practicality of the device.
