[0030] Example 1

[0031] The lean liquor produced by gold ore heap leaching contains recoverable carbon powder, which is characterized by its small particle size, large surface area, and strong adsorption capacity. Existing conventional solid separation equipment struggles to achieve ideal solid-liquid separation, resulting in poor carbon powder recovery and high recovery costs. For further information, please refer to [link to relevant documentation]. Figure 1 This application provides a powdered carbon recovery system 100, including: a feeding device 110, a vibrating screen device 120, and a powdered carbon collection 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 collection device 130; the vibrating screen device 120 includes: a screen box 121 and at least one electromagnetic vibrator 122; the bottom surface of the screen box 121 is a screen mesh, and at least one electromagnetic vibrator 122 is arranged on the screen mesh.

[0032] In this embodiment, at least one electromagnetic vibrator 122 is fixedly connected to the screen box 121 and slidably connected to the screen mesh. It receives control signals, determines the target vibration frequency and target amplitude based on the control signals, and vibrates at the target vibration frequency and target amplitude, thereby driving the screen mesh to vibrate. It can be understood that while the excitation force generated by at least one electromagnetic vibrator 122 drives the screen surface to vibrate, the screen box 121 remains stationary. Furthermore, at least one electromagnetic vibrator 122 approaches resonance during vibration, thereby achieving the target vibration frequency and target amplitude with a relatively small excitation force.

[0033] The feeding device 110 is used to obtain lean liquor and perform initial screening on the lean liquor to obtain initial screening lean liquor; the initial screening lean liquor is input into the vibrating screen device 120 through the output end of the feeding device 110 and the input end of the vibrating screen device 120; the vibrating screen 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 initial screening lean liquor; the powdered carbon collection device 130 is used to obtain the powdered carbon to be recovered and package it.

[0034] In this embodiment, lean liquor refers to the liquid generated during the gold ore leaching process, which contains carbon powder to be recovered. The input end of the feeding device 110 is used to obtain the lean liquor and perform initial screening. The pre-screened lean liquor obtained after initial screening is sequentially fed into the vibrating screen device 120 through the output end of the feeding device 110 and the input end of the vibrating screen device 120, where the vibrating screen device 120 further refines the pre-screened lean liquor. Specifically, this includes: at least one electromagnetic vibrator 122 in the vibrating screen device 120 vibrates, causing the screen to vibrate. It can be understood that the surface of the screen is provided with screen holes of a preset size. When the pre-screened lean liquor flows through the screen, the liquid in the pre-screened lean liquor separates from the carbon powder to be recovered. The liquid flows to the water tank below the screen, while the carbon powder to be recovered remains above the screen.

[0035] It is understood that the screen is tilted at a certain angle to the reference ground and tilted towards the output end of the vibrating screen device 120. At least one electromagnetic vibrator 122 drives the screen to vibrate. On the one hand, the high-frequency vibration can prevent the screen from clogging. On the other hand, during the vibration process, the powder and carbon to be recovered on the screen surface can be collected at the output end of the vibrating screen device 120 and then output to the downstream powder and carbon collection device 130 for packaging.

[0036] In one embodiment, the screen includes a plurality of screen panels, with adjacent screen panels snapping together.

[0037] In this embodiment, please refer to Figure 2 , Figure 2This diagram illustrates a connection between adjacent screen panels provided in an embodiment of this application. The screen is composed of multiple screen panels spliced ​​together, with adjacent screen panels interlocking. Specifically, a custom keychain can be used for connection to facilitate convenient replacement of screen panels. It is understood that the surface of each screen panel has a certain degree of hydrophobicity, reducing the viscous resistance to the carbon powder to be recovered during the screening process.

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

[0039] In this embodiment, the lower layer of the screen is a support layer with coarse wires and large pores, and the upper layer, tightly bonded to the support layer, is a composite mesh layer. The composite mesh layer consists of at least two layers of woven mesh with different pore sizes, each of which is made of stainless steel, and the pore size of the lower layer's woven mesh is much smaller than that of the upper layer's woven mesh. It can be understood that the pore size of each woven mesh constituting the composite mesh layer decreases sequentially from top to bottom. This reduces the residence time of the carbon powder to be recovered on the screen to a certain extent, improving the overall screening efficiency while reducing clogging.

[0040] It should be noted that the aperture and material of the support layer and each woven mesh can be selected according to actual needs. This is just an example and no restrictions are imposed.

[0041] In one implementation, please refer again Figure 1 The vibrating screen device 120 further includes: a water pressure driver 123 and an axial rotating brush 124; the water pressure driver 123 is disposed at the output end of the vibrating screen device 120 and is mechanically connected to the axial rotating brush 124; the axial rotating brush 124 is movably connected to the inner wall of the output end of the vibrating screen device 120; the water pressure driver 123 is used to monitor the current water level in the screen box 121, and when the current water level is greater than a preset water level height, it sends a drive signal to the axial rotating brush 124; the axial rotating brush 124 is used to rotate when the drive signal is received, so as to lightly brush the inner wall of the output end of the vibrating screen device 120 and prevent the output end of the vibrating screen device 120 from being blocked.

[0042] In this embodiment, to prevent the carbon powder to be recycled from clogging the output end of the vibrating screen 120, a water pressure driver 123 and an axial rotating brush 124 are provided at the output end of the vibrating screen 120. The water pressure driver 123 is driven by water pressure. When the water level in the vibrating screen 120 is higher than the preset water level, the water pressure driver 123 is started. By sending a drive signal to the axial rotating brush 124, the axial rotating brush 124 is controlled to rotate, so as to clean the inner wall of the output end of the vibrating screen 120, thereby avoiding clogging.

[0043] In one implementation, please refer again Figure 1 The feeding equipment 110 includes: a primary screening pipe 111, a primary screening screen 112, a powder and carbon collection tank 113, and a conveying pipe 114. The conveying pipe 114 includes: a first inlet and a second inlet, with the second inlet located below the first inlet. The primary screening pipe 111 is positioned above the primary screening screen 112, and its inlet end serves as the inlet end of the feeding equipment 110. The outlet end of the primary screening pipe 111 is fixedly connected to the first inlet. The powder and carbon collection tank 113 is positioned below the primary screening screen 112, and its outlet end is fixedly connected to the second inlet. The primary screening pipe 111 and the primary screening screen 112 are used for primary screening of the lean liquor.

[0044] In this embodiment, the lean liquor enters the feeding device 110 through the input end of the primary screening pipe 111. As the lean liquor flows through the primary screening pipe 111, it undergoes primary screening by the primary screening pipe 111 and the primary screening screen 112 installed below it. The liquid after primary screening, i.e., the primary screening lean liquor, enters the powder and carbon collection tank 113, and then sequentially enters the vibrating screen device 120 through the output end of the powder and carbon collection tank 113, the second input port of the conveying pipe 114, the output end of the conveying pipe 114, and the input end of the vibrating screen device 120. It can be understood that the output end of the primary screening pipe 111 is fixedly connected to the first input port of the conveying pipe 114. When the flow rate of the lean liquor entering the primary screening pipe 111 is too large, the lean liquor that has not undergone primary screening can be directly entered into the vibrating screen device 120 through the first input port of the conveying pipe 114, the output end of the conveying pipe 114, and the input end of the vibrating screen device 120 for fine screening.

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

[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 this embodiment, 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 screening lean liquid flowing through the pressure valve according to the drive control signal. In this embodiment, 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. The interactive device 150 determines the flow parameters according to the obtained flow signal and displays them.

[0048] In one implementation, please refer again Figure 1The powder and toner collection device 130 includes: a powder and toner collector 131, a powder and toner conveying pipe 132, and a powder and toner packaging machine 133; the powder and toner collector 131 is located below the output end of the vibrating screen device 120; the powder and toner collector 131 and the powder and toner packaging machine 133 are connected through the powder and toner conveying pipe 132.

[0049] In this embodiment, the powdered carbon collector 131 is located below the output end of the vibrating screen 120. It receives the powdered carbon to be recycled from the vibrating screen 120 and transports it to the powdered carbon packaging machine 133 via the powdered carbon conveying pipe 132 for packaging. It is understood that the powdered carbon to be recycled is transported to the powdered carbon packaging machine 133 via the powdered carbon conveying pipe 132 using gas.

[0050] In one implementation, please refer to Figure 3 , Figure 3 Another structural schematic diagram of the powdered carbon recovery system 100 provided in an embodiment of this application is shown. The powdered carbon recovery system 100 further includes: a control device 140, which is electrically connected to the feeding device 110, the vibrating screen device 120 and the powdered carbon collection device 130 respectively; the control device 140 is used to send drive control signals to the feeding device 110, the vibrating screen device 120 and the powdered carbon collection device 130 respectively.

[0051] It is understood that the control device 140 is electrically connected to the pressure valve in the ore feeding device 110, the electromagnetic vibrators 122 in the vibrating screen device 120, the powder and carbon collector 131 in the powder and carbon collection device 130, and the powder and carbon packaging machine 133, etc., respectively, to send corresponding drive control signals to each device in order to realize the automated control of the working parameters of each device, thereby realizing the automated recovery of the powder and carbon to be recovered and reducing labor costs.

[0052] In one embodiment, the powdered carbon recovery system 100 further includes: an interactive device 150 electrically connected to the control device 140; the interactive device 150 is used to acquire interactive signals and send interactive control signals to the control device 140 according to the interactive signals.

[0053] In this embodiment, each electromagnetic vibrator 122 is electrically connected to the interactive device 150 to acquire vibration parameters input by the user, such as the target amplitude, target frequency, and vibration interval time corresponding to each electromagnetic vibrator 122. The target amplitude includes constant vibration amplitude and strong vibration amplitude, and the target frequency includes constant vibration frequency and strong vibration frequency. It can be understood that, to improve screening efficiency, in this embodiment, the electromagnetic vibrator 122 uses a combination of instantaneous strong vibration and constant vibration to drive the screen vibration. The amplitude and frequency corresponding to constant vibration and strong vibration are set through the interactive device 150.

[0054] The powdered carbon recovery system provided in this invention includes: a feeding device, a vibrating screen device, and a powdered carbon collection device; the output end of the feeding device is opposite to the input end of the vibrating screen device; the output end of the vibrating screen device is opposite to the input end of the powdered carbon collection device; the vibrating screen device includes: 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 disposed on the screen mesh; this application obtains lean liquor through the feeding device and performs preliminary screening on the lean liquor to obtain preliminary screened lean liquor; the preliminary screened lean liquor 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 preliminary screened lean liquor; the powdered carbon collection device obtains the powdered carbon to be recovered and packages it, realizing automated collection and recovery of powdered carbon, improving the powdered carbon recovery efficiency while reducing the powdered carbon recovery cost.
