[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] Reference Figures 1 to 6 The present invention provides a multi-channel slurry analysis device, including a transmission mechanism 100, a sample preparation unit 200, a camera, and a sample measurement mechanism 300:

[0043] The transmission mechanism 100 includes an original cloth roller 110, a transmission belt 120 drawn from the original cloth roller 110, a workbench 130 suitable for supporting the transmission belt 120, and a winding roller 140, wherein the winding roller 140 is suitable for winding the transmission belt 120 extending from the workbench 130;

[0044] Above the workbench 130, a sample preparation unit 200, a camera, and a sample measuring mechanism 300 are sequentially arranged along the left and right directions:

[0045] The sample preparation unit 200 includes a plurality of sample preparation mechanisms 210 arranged in a front-to-back direction. The sample preparation mechanism 210 includes a mold 211, a lifting cylinder 212, and a sample supply nozzle 213. The lifting cylinder 212 is suitable for driving the mold 211 to abut against or away from the conveyor belt 120 on the workbench 130, so that the mold 211 and the conveyor belt 120 jointly define a molding cavity, or release the sample in the molding cavity. The sample supply nozzle 213 is suitable for flowing slurry into the molding cavity through the sample inlet 211a of the mold 211. The mold 211 is suitable for filtering out the slurry of the slurry to form a sample.

[0046] The camera is suitable for imaging the upper surface of the samples and the blank samples prepared by the plurality of sample preparation mechanisms 210. The central control system identifies the concave-convex morphology of the upper surface of each sample and whether there is a blank sample according to the imaging, and assigns corresponding numbers to each sample and the blank sample;

[0047] The sample measuring mechanism 300 includes a multi-axis motion structure 310 and a sample measuring probe 320 mounted on the multi-axis motion structure 310. The central control system calculates the motion data of the sample measuring probe 320 according to the concave-convex shape of the sample upper surface. The multi-axis motion structure 310 drives the sample measuring probe 320 to translate and / or swing according to the motion data. The sample measuring probe 300 performs a carpet detection on the sample upper surface. The sample measuring probe 320 measures the spectrum of the sample upper surface during movement. The central control system feeds back the composition and content of the sample with the corresponding number according to the spectrum composition and content. The blank sample has no sample to be measured, and the result with the corresponding number is directly fed back as the blank sample.

[0048] The original fabric roller 110 and the take-up roller 140 are rotatably connected to the frame, the take-up roller 140 is connected to the motor, the original fabric roller 110 is connected to the damper and / or the motor, and the take-up roller 140 takes up the conveyor belt 120, so that the conveyor belt 120 is pulled out from the original fabric roller 110 and dragged through the workbench 130. The conveyor belt 120 moves horizontally on the workbench 130 to obtain the sample, and then drives the sample to pass through the camera and the sample measuring mechanism 300 in sequence.

[0049] Reference Figure 1 The sample supply nozzle 213 is connected to the tested equipment (flotation equipment, etc.) through the sample supply pipe 410 and the first on-off valve 420 in turn to obtain slurry. The sample supply nozzle 213 is connected to the cleaning liquid through the sample supply pipe 410 and the second on-off valve 430 in turn. When sampling, the first on-off valve 420 is opened and the second on-off valve 430 is closed. When flushing the pipeline and the sample supply nozzle 213, the second on-off valve 430 is opened and the first on-off valve 420 is closed. According to the horizontality and curvature of the pipeline layout, the natural flow sampling of the slurry and the cleaning liquid may be relatively unsmooth; preferably, the sample supply nozzle 213 is connected to the first on-off valve 420 and the second on-off valve 430 through a sampling pump, that is, the sample supply pipe 410 is provided with a sampling pump.

[0050] The main body of the analysis device of the present invention (transmission mechanism 100, sample preparation unit 200, camera, sample measurement mechanism 300) is generally far away from the device to be measured (flotation device, etc.), or even in a separate room. The first on-off valve 420 and the second on-off valve 430 are placed close to the device to be measured, but far away from the sample supply nozzle 213. Therefore, in the overall sample supply line, the length of the pipeline between the first on-off valve 420 and the flotation device accounts for a small proportion, and the length of the sample supply tube 410 accounts for a large proportion. The sample supply tube 410 is cleaned to a certain extent, and the sample supply line after the slurry is cleaned to a large extent.

[0051] The first on-off valve 420 and the second on-off valve 430 can be common ball valves, which are manually controlled to be on or off; or they can be solenoid valves, which are controlled to be on or off by a central control system.

[0052] In the present invention, the multiple sample preparation mechanisms 210 can be used to synchronously take samples from multiple locations of a device under test, that is, to sample multiple samples from the same device under test, and can also be used to synchronously take single samples from multiple devices under test. Figure 1 Preferably, the sample supply nozzle 213 is connected to multiple devices under test through multiple first on-off valves 420, and the slurry analysis device prepares multiple ore samples of one device under test at a single time, and samples and prepares ore samples of multiple devices alternately.

[0053] Reference Figure 1 Furthermore, the middle of the sample supply tube 410 is connected to the cleaning liquid through the third on-off valve 440. The third on-off valve 440 is placed close to the sample supply nozzle 213 and away from the device under test. The third on-off valve 440 is a solenoid valve and is electrically connected to the central control system.

[0054] It is understandable that the central control system can be a control system such as a single chip microcomputer, PLC, PC, etc.

[0055] The water filter cartridge 211b may be a honeycomb structure made of carbon powder, coconut shell powder, etc., or may be made of cloth. Figures 4 to 7 , a water filter cartridge 211b is arranged at the lower end of the mold 211, and the cavity of the water filter cartridge 211b is suitable for forming the cavity; preferably, a mesh frame is arranged at the lower end of the mold 211, and the inner wall of the mesh frame is close to the outer wall of the water filter cartridge 211b, such as pasting, the water filter cartridge 211b is mainly suitable for filtering water, and the mesh frame is suitable for maintaining the shape of the water filter cartridge 211b to ensure the forming shape of the sample. The mesh size of the mesh frame is set according to the tension deformation and flexibility of the water filter mesh; when the hardness of the mesh frame and the water filter cartridge 211b is ensured, the mesh size of the mesh frame is selected to be larger.

[0056] In some settings, the filter cartridge 211b at the lower end of the mold 211 is natural filtrate, and the filtrate sample preparation rate is slow. Figure 6 In order to increase the filtrate rate of the mold 211, in some embodiments of the present invention, the lower end of the telescopic rod of the lifting cylinder 212 passes through the top of the mold 211 and is connected to a pressing block 214, and the telescopic rod of the lifting cylinder 212 is sleeved with a return spring 215. The upper end of the return spring 215 pushes the telescopic rod of the lifting cylinder 212, and the lower end pushes the top of the mold 211, so that the top of the mold 211 is normally against the pressing block 214; in addition, the pressing block 214 is suitable for squeezing the slurry in the water filter cartridge 211b.

[0057] For further information, see Figure 6 In design B, the conveyor belt 120 is a filter cloth, the workbench 130 is provided with a plurality of annular grooves 131 spaced apart in the front-to-back direction, and a support 132 suitable for being surrounded one-to-one by the annular grooves 131, a sewage outlet is provided at the lower end of the annular grooves 131, the support 132 is suitable for supporting the water filter cartridge 211b through the filter cloth, and the annular grooves 131 are suitable for collecting slurry seeping from the peripheral wall of the water filter cartridge 211b.

[0058] The filter cartridge 211b is formed into a sample, and when the pressing block 214 is away from the sample, the upper surface of the sample is prone to corrosion. The same method for improving the filtrate rate but with a smoother upper surface of the sample is as follows: Figures 2 to 5 , Figure 7 The conveyor belt 120 is a filter cloth, the workbench 130 is provided with a plurality of annular grooves 131 arranged at intervals along the front-to-back direction, and a support 132 suitable for being surrounded by the annular grooves 131 one-to-one, the annular grooves 131 are suitable for connecting to a pump, the mold 211 is covered with a water filter cartridge 211b, the inner wall of the lower end of the mold 211 and the outer wall of the water filter cartridge 211b define a drainage annular groove 211c, the support 132 is suitable for supporting the water filter cartridge 211b through the filter cloth, and the workbench 130 is suitable for supporting the mold 211 so that the drainage annular groove 211c docks with the annular groove 131.

[0059] Reference Figure 4 , Figure 5 Furthermore, the support platform 132 is provided with a sealing gasket suitable for being pressed down by the water filter cartridge 211b, and the workbench 130 is provided with a sealing ring suitable for being pressed by the lower end of the mold 211.

[0060] It is understandable that both the sampling pump and the drainage pump are types of water pumps, specifically pumps that can pump both slurry and pure liquid, such as centrifugal pumps, and their wear resistance requirements are relatively high.

[0061] Preferably, the camera is a CCD camera, a CMOS camera, etc. For example, a CCD camera is a digital camera with a charge-coupled device image sensor. It uses semiconductor devices to convert optical images into digital signals, can convert light into electric charges, store and transfer electric charges, capture a whole image at a time, or cut out a square area from it. The stored image can be transmitted to a printer, storage device or display screen. CCD cameras are widely used in industry for PCB board imaging and fixed-point patching, product pattern morphology analysis, and optimization or rejection.

[0062] The lifting cylinder 212 can be a pneumatic cylinder, an electric cylinder, or a hydraulic cylinder.

[0063] The multi-axis motion structure 310 includes multiple types of an X-axis linear motion component, a Y-axis linear motion component, a Z-axis linear motion component, an X-axis rotation component, a Y-axis rotation component, and a Z-axis rotation component, and the sample probe 320 translates and / or swings.

[0064] In the ore sample grade analysis, the sample probe 320 can be an X-ray fluorescence spectrometer, an electron pair effect and Compton scattered photon joint analyzer, a laser induced breakdown spectrometer, etc.

[0065] Reference Figure 1 , Figure 2 A multi-channel slurry analysis process includes a sampling step, a sample preparation step, a sample transfer step, a sample measurement and analysis step, and a cleaning step.

[0066] Sampling, the mold 211 and the water filter cartridge 211b are lowered, the support platform 132 supports the water filter cartridge 211b through the filter cloth, the water filter cartridge 211b and the conveyor belt 120 jointly define a molding cavity, the workbench 130 supports the lower end of the mold 211, so that the drainage ring groove 211c docks with the ring groove 131, the sample supply nozzle 213 is connected to the device under test through the sample supply tube 410, and the device under test flows into the molding cavity through the sample supply nozzle 213. The slurry submerges the drainage ring groove 211c. According to the required height H1 of the sample, the depth H2 of the drainage ring groove 211c is set, H1>H2, and it can be understood that the slurry height H3>H1; the sample height H1 is generally rated by the enterprise. On the other hand, in the management planning of some enterprises, the sample height is not rated, and the worker calls the mold 211 with different drainage ring groove 211c depths each time; so during the sample preparation, the negative pressure of the drainage ring groove 211c and the ring groove 131 is guaranteed. The mold 211 is detachably connected to the telescopic rod of the lifting cylinder 212 .

[0067] Sample preparation, the sample supply nozzle 213 stops feeding the sample into the mold 211, and the pump connected to the annular groove 131 is started for T1 time, such as 90 seconds, so that the annular groove 131 and the drainage annular groove 211c are under negative pressure, so that the slurry on the inner wall of the mold 211 slides cleanly to the molding cavity, so that the slurry in the molding cavity precipitates the ore liquid, and the mold 211 is molded to obtain a sample, and the upper surface of the sample is relatively smooth. It can be understood that the T1 time is set according to the total amount of slurry in the molding cavity.

[0068] The sample is transferred, the suction pump is paused, the mold 211 and the water filter cartridge 211b rise, the sample falls off due to its own weight and separates from the water filter cartridge 211b, and the demoulded sample is transferred to the bottom of the camera through the filter cloth. The camera simultaneously shoots the samples and / or blank samples on the filter cloth below it. The central control system identifies the concave and convex morphology of the upper surface of each sample and the existence of blank samples based on the imaging, and assigns corresponding numbers to each sample and blank sample.

[0069] For sample analysis, the central control system calculates the motion data of the sample probe 320 according to the concave-convex morphology of the sample surface. The multi-axis motion structure 310 drives the sample probe 320 to translate and / or rotate according to the motion data. The sample probe 320 measures the spectrum of the sample surface during movement. The central control system feeds back the components and contents of the corresponding numbered samples according to the spectral composition and content.

[0070] After cleaning, the mold 211 and the filter cartridge 211b are lowered, and the filter cartridge 211b and the conveyor belt 120 jointly define a molding cavity. The cleaning liquid is flushed to the sample supply nozzle 213 and the molding cavity through the sample supply tube 410, and the sample supply tube 410 and the sample supply nozzle 213 are rinsed. After the sewage obtained by rinsing is allowed to settle in the molding cavity for T2 time, such as 5 seconds, the pumping pump is started for T3 time, such as 10 seconds, and the sewage is precipitated into water. The obtained mineral mud is scattered on the filter cloth and is transferred with the filter cloth after the mold 211 rises. A very small amount of mineral mud remaining on the lower end edge of the filter cartridge 211b is finally added to the lower end of the new sample, which does not affect the composition of the upper surface of the new sample and does not affect the sampling of the new sample. There is no substantial impact between the two adjacent mineral samples of the same mold 211. The negative pressure pumping cleaning method makes the filter cartridge 211b, the drainage ring groove 211c and the ring groove 131 relatively clean and tidy. According to the actual situation, the flushing and pumping are performed once or multiple times in the cleaning step.

[0071] The cleaning step may occur during the sample imaging and / or sample analysis step.

[0072] It is understandable that demoulding does not need to wait until the ore sample is completely dried to adhere to the water filter cartridge 211b before demoulding. The ore sample can be demoulded and tested after it is formed by water extraction.

[0073] Compared with the prior art, the beneficial effects of the present application include: multiple slurry samples can be sampled and prepared simultaneously at a single time, and the sampling mechanism 300 can measure the multiple slurry samples at a single time based on the same image and store them in a coordinated manner, which makes it easy to form a standardized database; mechanized sampling, sample preparation and transmission, image recognition and automatic sampling are used to improve the sampling efficiency and quality.

[0074] In some embodiments of the present invention, the inner wall of the mold is provided with an atomizing spray hole, the atomizing spray hole is connected to the demoulding agent through the drug supply pipe, the fourth on-off valve and the drug supply pump, and the atomizing spray hole is connected to the atmosphere through the drug supply pipe and the fifth on-off valve. In the sampling step, the mold 211 is lowered into place, the fourth on-off valve is opened, and the drug supply pump sprays the atomizing demoulding machine into the cavity of the water filter cylinder 211b through the atomizing spray hole, and then the fourth on-off valve is closed and the molding cavity is filled with slurry. In the sampling step, the fourth on-off valve is closed and the fifth on-off valve is opened. Under the suction of the pump, the drug supply pipe is ventilated and cleaned, and the air intake of the drug supply pipe is synchronously suitable for driving out the slurry of the slurry.

[0075] Reference Figure 4 , Figure 5 In some embodiments of the present invention, the inner bottom of the annular groove 131 is an inclined plane, and the sewage outlet of the annular groove 131 is set at a position corresponding to the lower end of the inner bottom of the annular groove 131. During negative pressure pumping, the suction is performed quickly and effectively to improve the cleanliness of the ore liquid and sewage pumping.

[0076] Reference Figures 1 to 4In some embodiments of the present invention, a slide 216 and a dirt collecting tank 217 are further included. The sample supply nozzle 213 is arranged on the slide 216. The slide 216 is transmission-connected with a positioning power component, such as a motor and a screw nut pair, a motor and a belt pair, a cylinder, etc. The positioning power component is suitable for driving the slide 216 and the sample supply nozzle 213 to move left and right, so that the sample supply nozzle 213 alternately corresponds to the sample inlet 211a of the mold 211 and the dirt collecting tank 217.

[0077] Reference Figures 1 to 4 In the sampling step, the mold 211 is lowered into place, and after the sample supply nozzle 213 discharges slurry above the sump 217, the slide 216 drives the sample supply nozzle 213 toward the sampling port 211a of the mold 211. After the sample supply nozzle 213 pours slurry into the sampling port 211a of the mold 211 for T4 time, the sample supply nozzle 213 returns to the sump 217. At this time, the sampling port 211a of the mold 211 is used as a vent. After the sample supply nozzle 213 discharges slurry, it pours slurry for T4 time, such as 3 seconds, to ensure that a sufficient amount of slurry H3 is poured into the molding cavity. Furthermore, in the cleaning step, after the sample supply nozzle 213 flushes the cleaning liquid into the mold 211, it is also suitable for flushing the cleaning liquid into the sump 217.

[0078] Furthermore, the sample supply nozzle 213 is provided with a flow meter, and the flow meter and the position adjustment power part are electrically connected to the central control system.
