[0030] Example 1

[0031] The barren liquid produced by heap leaching of gold mines contains powdered carbon to be recovered. The powdered carbon to be recovered in the barren liquid has the characteristics of small particle size, large surface area, and strong adsorption capacity. Conventional solid separation equipment provided by the prior art is difficult to achieve the ideal solid-liquid separation effect. The powdered carbon recovery effect in the prior art is poor and the recovery cost is high. For this, please refer to Figure 1 The embodiment of the present application provides a powdered carbon recovery system 100, comprising: a feeding device 110, a vibrating screen device 120 and a powdered carbon collecting device 130; the output end of the feeding device 110 is arranged opposite to the input end of the vibrating screen device 120; the output end of the vibrating screen device 120 is arranged opposite to the input end of the powdered carbon collecting device 130; the vibrating screen device 120 comprises: a screen box 121 and at least one electromagnetic vibrator 122; the bottom surface of the screen box 121 is a screen, and at least one electromagnetic vibrator 122 is arranged on the screen.

[0032] In the embodiment of the present application, at least one electromagnetic vibrator 122 is fixedly connected to the screen box 121 and slidably connected to the screen, and is used to receive a control signal, and determine a target frequency and a target amplitude according to the control signal, and vibrate at the target frequency and the target amplitude, thereby driving the screen to vibrate. It can be understood that while the exciting force generated by at least one electromagnetic vibrator 122 drives the screen surface to vibrate, the screen box 121 remains stationary. In addition, at least one electromagnetic vibrator 122 is close to resonance when vibrating, thereby achieving the target frequency and the target amplitude with a smaller exciting force.

[0033] The feeding device 110 is used to obtain the lean liquid and preliminarily screen the lean liquid to obtain the preliminarily screened lean liquid; the preliminarily screened lean liquid is input into the vibrating device 120 through the output end of the feeding device 110 and the input end of the vibrating device 120; the vibrating device 120 is used to drive the screen to vibrate through at least one electromagnetic vibrator 122 to screen out the powdered carbon to be recovered from the preliminarily screened lean liquid; the powdered carbon collection device 130 is used to obtain the powdered carbon to be recovered and pack it.

[0034] In this embodiment, the lean liquid refers to the liquid generated during the gold leaching process, and the lean liquid contains powdered carbon to be recovered. The input end of the ore feeding device 110 is used to obtain the lean liquid and perform preliminary screening on the lean liquid. The pre-screened lean liquid obtained after the preliminary screening is sequentially input into the vibrating screen device 120 through the output end of the ore feeding device 110 and the input end of the vibrating screen device 120, and the vibrating screen device 120 further performs fine screening on the pre-screened lean liquid. Specifically, it includes: at least one electromagnetic exciter 122 in the vibrating screen device 120 vibrates to drive the screen to vibrate. It can be understood that the surface of the screen is provided with sieve holes of a preset size. When the pre-screened lean liquid flows through the screen, the liquid in the pre-screened lean liquid is separated from the powdered carbon to be recovered, and the liquid flows to the water tank below the screen, and the powdered carbon to be recovered is retained above the screen.

[0035] It can be understood that the screen is inclined at a certain angle to the reference ground and is inclined toward the output end of the vibrating screen device 120. At least one electromagnetic exciter 122 drives the screen to vibrate. On the one hand, high-frequency vibration can be used to avoid screen blockage. On the other hand, during the vibration process, the powdered carbon to be recovered on the surface of the screen can be collected to the output end of the vibrating screen device 120, and then output to the downstream powdered carbon collection device 130 for packaging.

[0036] In one embodiment, the screen comprises: a plurality of screen sheets, and adjacent screen sheets are clamped together.

[0037] In this example, see Figure 2 , Figure 2A schematic diagram of a connection between adjacent screen sheets provided in an embodiment of the present application is shown. The screen is made up of a plurality of screen sheets, and the adjacent screen sheets are connected by snapping. Specifically, a customized keychain can be provided to connect the screen sheets so as to realize convenient replacement of the screen sheets. It can be understood that the surface of each screen sheet has a certain hydrophobicity, which reduces the viscous resistance to the recovered powdered carbon during the screening process.

[0038] In one embodiment, the screen sheet includes: a support mesh layer and a composite mesh layer, wherein the composite mesh layer is composed of at least two layers of woven meshes with different mesh apertures; the support mesh layer is located below the composite mesh layer and is slidably connected to at least one of the electromagnetic exciters 122 .

[0039] In this embodiment, the lower layer of the screen is a support mesh layer with coarse wire and large holes, and the upper layer tightly bonded to the support mesh layer is a composite mesh layer, which is composed of at least two layers of woven meshes with different apertures, wherein each woven mesh is made of stainless steel, and the aperture size of the woven mesh located in the lower layer is much smaller than the aperture size of the woven mesh located in the upper layer. It can be understood that the apertures of each woven mesh constituting the composite mesh layer decrease from the upper layer to the lower layer, which to a certain extent reduces the residence time of the recovered powdered carbon on the screen, improves the overall screening efficiency and reduces blockage.

[0040] It should be noted that the aperture and material of the support mesh layer and each woven mesh can be selected according to actual needs, which is only used as an example and not a limitation.

[0041] In one embodiment, see again Figure 1 The vibrating screen device 120 also includes: a hydraulic driver 123 and an axially rotating brush 124; the hydraulic driver 123 is arranged at the output end of the vibrating screen device 120 and is mechanically connected to the axially rotating brush 124; the axially rotating brush 124 is movably connected to the inner wall of the output end of the vibrating screen device 120; the hydraulic driver 123 is used to monitor the current water level in the screen box 121, and when the current water level is greater than the preset water level height, a driving signal is sent to the axially rotating brush 124; the axially rotating brush 124 is used to rotate when the driving signal is obtained to lightly brush the inner wall of the output end of the vibrating screen device 120 to prevent the output end of the vibrating screen device 120 from being blocked.

[0042] In this embodiment, in order to prevent the recovered powdered carbon from clogging the output end of the vibrating device 120, a hydraulic driver 123 and an axial rotating brush 124 are provided at the output end of the vibrating device 120, wherein the hydraulic driver 123 is driven by hydraulic power. When the water level in the vibrating device 120 is greater than the preset water level, the hydraulic driver 123 is started, and a driving signal is sent to the axial rotating brush 124 to control the rotation of the axial rotating brush 124 to clean the inner wall of the output end of the vibrating device 120, thereby avoiding clogging.

[0043] In one embodiment, see again Figure 1 The ore feeding equipment 110 includes: a primary screening pipe 111, a primary screening net 112, a powdered carbon collection tank 113 and a conveying pipe 114, the conveying pipe 114 includes: a first input port and a second input port, the second input port is located below the first input port; the primary screening pipe 111 is arranged above the primary screening net 112, and the input end of the primary screening pipe 111 serves as the input end of the ore feeding equipment 110; the output end of the primary screening pipe 111 is fixedly connected to the first input port; the powdered carbon collection tank 113 is arranged below the primary screening net 112, and the output end of the powdered carbon collection tank 113 is fixedly connected to the second input port; the primary screening pipe 111 and the primary screening net 112 are used for primary screening of the lean liquid.

[0044] In this embodiment, the lean liquid enters the ore feeding device 110 through the input end of the primary screening pipeline 111. When the lean liquid flows through the primary screening pipeline 111, it is preliminarily screened by the primary screening pipeline 111 and the primary screening net 112 arranged below the primary screening pipeline 111. The liquid after the preliminarily screening, i.e., the preliminarily screened lean liquid, enters the powdered carbon collection tank 113, and is sequentially input into the vibrating screen device 120 through the output end of the powdered carbon collection tank 113, the second input port of the conveying pipeline 114, the output end of the conveying pipeline 114, and the input end of the vibrating screen device 120. It can be understood that the output end of the primary screening pipeline 111 is fixedly connected to the first input port of the conveying pipeline 114. When the flow rate of the lean liquid input into the primary screening pipeline 111 is too large, the lean liquid that has not been preliminarily screened can be directly input into the vibrating screen device 120 through the first input port of the conveying pipeline 114, the output end of the conveying pipeline 114, and the input end of the vibrating screen device 120, and fine screening is performed by the vibrating screen device 120.

[0045] In one embodiment, the delivery pipeline 114 further includes an output port, which serves as an output end of the ore feeding device 110 ; a pressure valve and a flow meter are fixedly connected to the inner wall of the output port.

[0046] In this embodiment, the pressure valve is used to control the flow rate of the outflowing primary screening lean liquid, and the flow meter is used to count the flow rate of the outflowing primary screening lean liquid.

[0047] It should be noted that in the embodiment of the present application, the pressure valve is electrically connected to the control device 140, and is used to obtain a drive control signal from the control device 140, and control the flow rate of the primary screened lean liquid flowing through the pressure valve according to the drive control signal. In the embodiment of the present application, the flow meter is electrically connected to the interactive device 150, and is used to send the monitored flow signal to the interactive device 150, and the interactive device 150 determines and displays the flow parameter according to the acquired flow signal.

[0048] In one embodiment, see again Figure 1The powdered carbon collection device 130 includes: a powdered carbon collector 131, a powdered carbon conveying pipeline 132 and a powdered carbon packaging machine 133; the powdered carbon collector 131 is arranged below the output end of the vibrating screen device 120; the powdered carbon collector 131 is connected to the powdered carbon packaging machine 133 through the powdered carbon conveying pipeline 132.

[0049] In this embodiment, the powdered carbon collector 131 is disposed below the output end of the vibrating screen device 120, and is used to receive the powdered carbon to be recovered output by the vibrating screen device 120, and to transport the powdered carbon to be recovered to the powdered carbon packaging machine 133 through the powdered carbon conveying pipeline 132, and to be packaged by the powdered carbon packaging machine 133. It can be understood that the powdered carbon to be recovered is transported to the powdered carbon packaging machine 133 through the powdered carbon conveying pipeline 132 using gas.

[0050] In one embodiment, see Figure 3 , Figure 3 Another structural schematic diagram of the fine carbon recovery system 100 provided in an embodiment of the present application is shown. The fine carbon recovery system 100 further includes: a control device 140, which is electrically connected to the ore feeding device 110, the vibrating screen device 120 and the fine carbon collection device 130 respectively; the control device 140 is used to send a driving control signal to the ore feeding device 110, the vibrating screen device 120 and the fine carbon collection device 130 respectively.

[0053] In this embodiment, each electromagnetic vibrator 122 is electrically connected to the interactive device 150, respectively, to obtain the vibration parameters input by the user, for example: the target amplitude, target frequency and vibration interval time corresponding to each electromagnetic vibrator 122, wherein the target amplitude includes: the normal vibration amplitude and the strong vibration amplitude, and the target frequency includes: the normal vibration frequency and the strong vibration frequency. It can be understood that in order to improve the screening efficiency, in the embodiment of the present application, the electromagnetic vibrator 122 drives the screen to vibrate by combining instantaneous strong vibration with normal vibration, wherein the amplitude and frequency corresponding to the normal vibration and the strong vibration are set through the interactive device 150.

[0054] The powdered carbon recovery system provided by the embodiment of the present invention comprises: a feeding device, a vibrating screen device and a powdered carbon collection device; the output end of the feeding device is arranged opposite to the input end of the vibrating screen device; the output end of the vibrating screen device is arranged opposite to the input end of the powdered carbon collection device; the vibrating screen device comprises: a screen box and at least one electromagnetic vibrator; the bottom surface of the screen box is a screen mesh, and at least one electromagnetic vibrator is arranged on the screen mesh; the present application obtains a lean liquid through the feeding device, and preliminarily screens the lean liquid to obtain a pre-screened lean liquid; the pre-screened lean liquid is input into the vibrating screen device through the output end of the feeding device and the input end of the vibrating screen device; the vibrating screen device drives the screen mesh to vibrate through at least one electromagnetic vibrator to screen out the powdered carbon to be recovered from the pre-screened lean liquid; the powdered carbon collection device obtains the powdered carbon to be recovered and packs it, realizing the automatic collection belt to recover the powdered carbon, which improves the powdered carbon recovery efficiency and reduces the powdered carbon recovery cost.
