Description

Technical Field

[0001] The utility model belongs to the technical field of mineral processing, and in particular relates to an online ore pulp multi-element grade analysis system. Background Art

[0002] At present, grade is one of the most important process indicators in the production process of the mineral processing industry. It is necessary to timely understand the content of the grade of relevant elements in the slurry so that the production equipment parameters can be adjusted in time to guide production.

[0003] Conventional automatic graders on the market mainly detect the element grade in the ore slurry directly, and the window that contacts the ore slurry is easily worn; at the same time, when a single channel is used to detect the slurry in multiple process pipelines, the incomplete flushing of the window will cause certain interference to the test results. Utility Model Content

[0004] Based on the technical problems existing in the prior art, the utility model proposes an online slurry multi-element grade analysis system, which aims to solve the problem that the existing grader detects elements in direct contact with the slurry, resulting in low detection accuracy.

[0005] The utility model proposes an online slurry multi-element grade analysis system, which includes a filtering component, a cake drying component, a cake crushing component and a mineral powder pressing component; the filtering component is used to filter out liquid in the slurry to form a mineral-containing filter block; the cake drying component is used to dry the mineral-containing filter block to obtain a dried filter block; the cake crushing component is used to crush the dried filter block to obtain mineral powder; the mineral powder pressing component is used to press the mineral powder into a sample cake for detection, the cake crushing component includes a crushing shell, a crushing disk, a crushing drive mechanism and a feeding mechanism, the feeding mechanism is used to convey the dried filter block to the crushing disk, the crushing disk is rotatably arranged inside the crushing shell, and is used to crush the dried material block conveyed by the feeding mechanism, so that the dried material block is crushed to form mineral powder; the crushing drive mechanism is used to drive the crushing disk to rotate.

[0006] Furthermore, the filter assembly, the cake drying assembly, and the mineral powder pressing assembly are arranged sequentially from top to bottom in spatial height. Preferably, the filter assembly is disposed at the uppermost end and fixed to the first fixed base, with the liquid inlet of the filter assembly located at the top for inputting the slurry and allowing the slurry to flow downward to be filtered through the filter assembly, thereby removing the liquid in the slurry and achieving a stratified cake-like state with a high moisture content. The solid minerals in the slurry form a mineral-containing filter block, thereby obtaining a mineral-containing filter block.

[0007] Preferably, the mineral powder pressing assembly is disposed at the lowest end and can be fixed to the second fixed base. A height difference exists between the filter assembly and the mineral powder pressing assembly. The cake drying assembly and the cake crushing assembly are disposed between the filter assembly and the mineral powder pressing assembly, and both the cake drying assembly and the cake crushing assembly can be fixed to the mineral powder pressing assembly. The feed end of the cake drying assembly extends into the interior of the filter assembly to receive the mineral-containing filter blocks obtained by the filter assembly. The cake drying assembly then dries the mineral-containing filter blocks to reduce their moisture content, thereby forming dried filter blocks.

[0008] Furthermore, a cake crushing assembly is disposed below the cake drying assembly, and its feed port is connected to its discharge port. The cake crushing assembly crushes the dried filter cake to obtain mineral powder, achieving uniform cake crushing. A mineral powder pressing assembly is disposed below the cake crushing assembly.

[0009] Furthermore, the mineral powder pressing assembly is equipped with a sample ring, allowing mineral powder discharged from the cake crushing assembly's outlet to fall into the sample ring, where it is then compressed by the mineral powder pressing assembly. The crushing shell is located between the cake drying assembly and the mineral powder pressing assembly and is bolted to the top of the mineral powder pressing assembly. The crushing disc and feed mechanism are housed within the crushing shell, with the feed mechanism located on one side of the crushing disc and the other side connected to the power output of the crushing drive mechanism. The crushing drive mechanism drives the crushing disc to rotate, crushing the dried filter cake and producing mineral powder.

[0010] Compared with the existing technology, the online slurry multi-element grade analysis system provided by the utility model uses a sample preparation device to prepare the incoming slurry to convert the slurry into a solid cake to obtain a solid cake; the solid cake is transported to the pre-detection position on the side of the element detection device by a transport device, and the solid cake is detected by the element detection device. Non-contact detection can be used, eliminating the need for direct contact detection through the detection window. At the same time, the elements of the solid cake will not contaminate the detection window, avoiding contamination and wear of the detection window, and solving the problem of low detection accuracy caused by the existing grade meter detection of elements through direct contact with the slurry. At the same time, because the direct target sample for detection is a solid cake, and the preparation of the solid cake is not affected by concentration, the system's high accuracy and stability are indirectly guaranteed. The solid cake is not affected by slurry concentration, thereby improving the accuracy of the detection results. Therefore, the system can simultaneously detect multiple element grades with high detection accuracy, which is not affected by slurry concentration. The key components are not contaminated or worn, have a long service life, and are easy to maintain. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0052] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art. It should be noted that, unless there is a conflict, the embodiments of the present invention and the features described in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0053] See also Figure 1 , which is the preferred structure of the online slurry multi-element grade analysis system provided by the embodiment of the utility model. As shown in the figure, the system includes: sample preparation equipment 1, handling equipment 2 and element detection equipment 3;

[0054] The sample preparation equipment 1 is used to perform solid sample preparation on the inflowing ore pulp to convert the slurry into a solid cake to obtain a solid cake; the transportation equipment 2 is used to transport the solid cake to the pre-detection position; the element detection equipment 3 is used to perform element detection on the solid cake located at the pre-detection position to obtain the element grade in the solid cake, and then obtain the element grade in the ore pulp.

[0055] Specifically, the element detection device 3 and the sample preparation device 1 are installed side by side on the chassis 4. When the plane of the integrated machine is controlled facing the element detection device 3, the element detection device 3 is on the left, and the sample preparation device 1 is on the right side of the element detection device 3 and is in contact with the element detection device 3. That is to say, the sample preparation device 1 and the element detection device 3 are arranged side by side on both sides of the chassis 4 (such as Figure 1 The pre-detection position is located on the side where the element detection device 3 is located (as shown in the left and right sides along the X direction). Figure 1 The transport device 2 can be set on the base frame 4 to transport the solid cake, so as to transport the solid cake prepared by the sample preparation device 1 to the pre-detection position on the side where the element detection device 3 is located, so that the solid cake can be tested for elements by the element detection device 3. In this embodiment, the element detection device 3 can use X-ray fluorescence to perform non-contact element detection on the solid cake. Figure 1 As shown, in this embodiment, there are two sample preparation devices 1. Of course, the number of sample preparation devices 1 may also be one, three, or other numbers. This embodiment does not limit the number of sample preparation devices 1. In this embodiment, an electromagnetic automatic double-leaf door 5 may be provided between the element detection device 3 and the sample preparation device 1. The electromagnetic automatic double-leaf door 5 is configured to open when the transport device 2 is transporting the solid cake, allowing the transport device 2 to transport the solid cake from the electromagnetic automatic double-leaf door 5 to the detection station, and to close and seal the element detection device 3 to prevent radiation from the element detection device 3.

[0056] See also Figure 2 and Figure 3 , which shows the preferred structure of the sample preparation device provided by the embodiment of the utility model. As shown in the figure, the sample preparation device 1 includes a filtering component 11, a cake drying component 12, a cake crushing component 13 and a mineral powder pressing component 14;

[0057] The filtering component 11 is used to filter the inflowing ore pulp so that the solid minerals in the ore pulp form a mineral cake; the cake drying component 12 is used to dry the mineral cake obtained by filtering the filtering component to obtain dried cake blocks; the cake block crushing component 13 is used to crush the dried cake blocks obtained by drying the cake drying component to obtain mineral powder; the mineral powder pressing component 14 is used to press the mineral powder crushed by the cake block crushing component to press the mineral powder into a solid cake.

[0058] Specifically, the filter assembly 11, the cake drying assembly 12 and the mineral powder pressing assembly 14 are arranged from top to bottom (relative to the Figure 2 The filter assembly 11 is disposed at the uppermost end and can be fixed to the first fixed base 15. The liquid inlet of the filter assembly 11 is located at the top to input the slurry and allow the slurry to flow downward to be filtered through the filter assembly 11. The liquid in the slurry is filtered out, and the slurry is initially in a high moisture and layered cake state. The solid minerals in the slurry form a ore-containing cake, thereby obtaining a ore-containing cake. The mineral powder pressing component 14 is arranged at the lowest end and can be fixed on the second fixed machine base 16. The filter component 11 and the mineral powder pressing component 14 have a height difference. The cake drying component 12 and the cake crushing component 13 are arranged between the filter component 11 and the mineral powder pressing component 14. The cake drying component 12 and the cake crushing component 13 can be fixed on the mineral powder pressing component 14, and the feeding end of the cake drying component 12 can extend into the interior of the filter component 11 to receive the mineral cake obtained by the filter component 11, and the mineral cake is dried by the cake drying component 12 to reduce the water content so that the mineral cake forms a dried cake block. The cake crushing component 13 is arranged on one side of the cake drying component 12 (such as Figure 2The left side shown in the figure) is connected to the feeding end of the cake crushing assembly 13 and the discharging end of the cake drying assembly 12, so that the dried cake is crushed by the cake crushing assembly 13 to obtain mineral powder, thereby achieving a uniform crushing state of the cake. The mineral powder pressing assembly 14 is arranged below the cake crushing assembly 13, and the mineral powder pressing assembly 14 may be provided with a sample ring 17, so that the mineral powder discharged from the discharging end of the cake crushing assembly 13 falls into the sample ring 17, and the mineral powder pressing assembly 14 presses the mineral powder in the sample ring 17 to obtain a solid cake, and then the element grade of the solid cake is detected. The element grade detection of the solid cake can be carried out by using existing conventional detection sensors, and the solid cake is indirectly detected by non-contact to obtain the element grade of the slurry. The first fixed machine base 15 and the second fixed machine base 16 play a supporting role. The two can be an integrated structure or two independent fixed machine bases. There is no limitation on this in this embodiment.

[0059] In this embodiment, a liquid collecting tank 18 is further provided below the filter assembly 11 to allow the liquid filtered out of the filter assembly 11 to be discharged into the liquid collecting tank 18. The liquid collecting tank 18 may also be connected to a drain pipe 19 for discharging the liquid or other materials in the liquid collecting tank 18 into the slurry pool.

[0060] See also Figures 4 to 7 , which shows the preferred structure of the filter assembly provided by the embodiment of the utility model. As shown in the figure, the filter assembly 11 includes: a filter base 111, a filter container 112, an air compressor (not shown in the figure), a filter flap 113, a removal mechanism 114 and a locking mechanism 115;

[0061] The filter base 111 plays a supporting role; the bottom end of the filter container 112 is opened, and the filter container 112 is arranged on the filter base 111. The filter container 112 is provided with a liquid inlet pipe 1121 for injecting slurry into the filter container 112; the air compressor is connected to the filter container 112 for pressurizing the filter container 112 so that the slurry in the filter container 112 can be filtered under the action of positive pressure; the filter flap 113 is movably arranged on the filter base 111, and the filter flap 113 has a blocked state and an open state. In the blocked state, the filter flap 113 blocks the open end of the filter container 112, and a closed and sealed chamber is formed in the filter container 112, so that the liquid in the slurry flows out from the hole position of the filter flap 113 to the outside of the filter container 112 under the action of positive pressure, and the solid minerals in the slurry remain on the filter flap 113 to form a mineral cake; the removal mechanism 114 is arranged on one side of the filter flap 113 (such as Figure 7 The filter flap 113 is in the open state, and is used to apply force to the cake on the filter flap 113 so that the cake is blown off the filter flap 113 and falls into the cake drying assembly 12.

[0062] Specifically, the filter base 111 supports the filter container 112, the filter flap 113, the ejection mechanism 114, and the locking mechanism 115. A flap opening is provided on the top plate of the filter base 111. The filter container 112 is positioned above the filter base 111, and the open end of the filter container 112 extends from the flap opening into the interior of the filter base 111. The top of the filter container 112 serves as a feed port, connected to a liquid inlet pipe 1121 for injecting slurry into the filter container 112. The filter container 112 can also be connected to an air compressor to pressurize the interior of the filter container 112. Specifically, the air pressure from the air compressor is pumped into the filter container 112, draining the water in the filter container 112 into the sump 18 through positive pressure, and then out into the slurry pool through the drain pipe 19. The filter flap 113 is movably arranged on the filter base 111. Preferably, the filter flap 113 is rotatably arranged at the open end of the filter container 112 to rotate to the position as shown in FIG. Figure 5 In the blocked state shown, the filter flap 113 blocks the open end of the filter container 112. The filter flap 113 is provided with a filter hole, so that the liquid in the slurry can flow out from the filter hole and prevent the solid minerals in the slurry from flowing out, so that the liquid in the slurry flows out from the hole position of the filter flap 113 to the outside of the filter container 112 under the action of positive pressure, and the solid minerals in the slurry remain on the filter flap 113 to form a mineral cake. There may be two removal mechanisms 114, which are respectively provided on both sides of the filter flap 113. In this embodiment, there may be two removal mechanisms 114, which are respectively provided on both sides of the filter flap 113. The cake air knife may be tilted and arranged in parallel with the filter flap 113 in the open state, so that when the filter flap 113 is rotated to the open state, the mineral cake is blown off, that is, when the filter flap 113 is in the open state, the cake on the filter flap 113 is sprayed, that is, a blowing force is applied to the cake so that the cake is blown off from the filter flap 113 and falls into the cake drying assembly 12. Of course, in other embodiments, the removal mechanism 114 may also be other removal mechanisms, such as a scraping mechanism, which is used to apply a scraping force to the cake so that the cake can fall.

[0063] In this embodiment, in order to prevent the filter flap 113 from rotating and opening during the filtration process, preferably, a locking mechanism 115 is further provided on the filter base 111 for locking the filter flap 113 on the filter base 111 when the filter flap 113 is in the blocked state, so as to ensure the stability of the filter flap 113 in blocking and filtering. Specifically, there can be two locking mechanisms 115, one on each side of the filter flap 113 (relative to the other side). Figure 4The locking mechanism 115 can be a self-locking pneumatic clamp to clamp the filter flap 113 in the blocked state, thereby achieving pressure locking and release of the filter flap 113. The locking mechanism 115 can also be other locking structures, which are not limited in this embodiment.

[0064] Continue to see Figures 4 to 7 The filter flap 113 may also be connected to a flap drive mechanism 116 for driving the filter flap 113 to rotate so that the filter flap can switch between different states. Specifically, the filter base 111 may be provided with a flap pin seat 117, and the fixing seat of the flap drive mechanism 116 may also be mounted on the filter base 111. Both the flap pin seat 117 and the fixing seat of the flap drive mechanism 116 may be fixed to the filter base 111 via bolts or other connecting members. The power output end of the flap driving mechanism 116 can be passed through the top plate of the filter base 111 and extend to the interior of the filter base 111. In addition, a connecting ear 18 is provided on the power output end of the flap driving mechanism 116, and a connecting ear 18 located inside the filter base 111 can also be provided on the flap pin seat 117. In addition, the connecting ear on the flap pin seat 117 is located between the opening end of the filter container 112 and the connecting ear on the flap driving mechanism 116. The filter flap 113 is rotatably connected to the connecting ear on the flap pin seat 117 and the connecting ear on the flap driving mechanism 116 through a pin shaft, and is used to drive the filter flap 113 to rotate around the connecting ear on the flap pin seat 117 under the driving action of the power output end of the flap driving mechanism 116 to realize state switching. The flap drive mechanism 116 can be a flap cylinder structure, and its power output end is arranged downward, which is used to push the left end of the filter flap 113 to move up and down, so that the filter flap 113 can rotate around the connecting ear on the flap pin seat 117. That is to say, when filtering work is required, the flap cylinder structure, that is, the power output end of the flap drive mechanism 116, is extended, and the filter flap 113 is closed into place, that is, rotated to a blocked state; after the filtering is completed, the flap cylinder structure, that is, the power output end of the flap drive mechanism 116 is retracted, and the filter flap 113 is opened into place, that is, rotated to an open state.

[0065] Continue to see Figure 5A filter drain trough 119 is provided below the filter flap 113 to collect liquid flowing from the filter flap 113. Specifically, the filter drain trough 119 is installed below the filter flap 113 and can swing with the swing of the filter flap 113. In this embodiment, the filter drain trough 119 can be connected to an inclined drainage pipe, whose outlet can be located in the sump 18. This allows the water in the filter container 112 to be discharged into the sump 18 through the filter drain trough 119 and the drainage pipe under positive pressure, and then discharged into the slurry tank.

[0066] Continue to see Figure 5 and Figure 6 A filter trough 111 is also provided on the filter base 111 below the filter flap 113, allowing the cake to fall into the trough 111 and, under the guidance of the trough 111, fall into the cake drying assembly 12. Specifically, the filter trough 111 is disposed within the filter base 111. The mineral cake can fall along the top wall of the filter flap 113 under the action of spraying or scraping, and then fall downward into the filter trough 111 under the restraining action of the side panels of the filter base 111. The discharge port of the filter trough 111 can be arranged downward, allowing the mineral cake to fall into the cake drying assembly 12 under the action of gravity.

[0067] In this embodiment, the filter container 112 is further provided with a liquid level sensor 1122. The liquid level sensor 1122 may be an electronic liquid level gauge for detecting the slurry level within the filter container 112. When the slurry level within the filter container 112 reaches a preset level, the slurry input to the filter container 112 is terminated, thereby controlling the slurry input to the filter container 112 prior to filtration. The filter container 112 may also be provided with a pressure switch 1123 for detecting the pressure within the filter container 112. When the pressure within the filter container 112 reaches a preset pressure, i.e., when it exceeds the preset pressure, the switch opens to connect the filter container 112 to the external atmosphere, thereby controlling the filtration effect within the filter container 112 to avoid under-filtration or over-filtration of the cake.

[0068] Continue to see Figure 4 and Figure 6The liquid inlet pipe 1121 is connected to a slurry inlet connector 1124, which has three communication channels: a gas channel, a liquid level measurement channel, and a liquid inlet channel. Each communication channel is connected to the liquid inlet pipe 1121 and the filter container 112. A liquid level sensor 1122 is installed on the slurry inlet connector 1124. The liquid level sensor 1122 is installed in the liquid level measurement channel and the liquid inlet pipe 1121 to detect the slurry level in the filter container 112. A pressure switch 1123 is installed on the side wall of the slurry inlet connector 1124 and is connected to the gas channel. The pressure switch 1123 is used to measure the pressure in the gas channel, the liquid inlet pipe 1121, and the filter container 112, and to control the flow between the atmosphere and the gas channel. An air inlet hole 11241 is also provided on the side wall of the slurry inlet connector 1124, which is connected to the gas channel. The air inlet hole 11241 can be provided with an air inlet joint for connecting an air compressor to provide air pressure, i.e., pressurization, to the filter container 112. A slurry inlet seat 1125 is also connected to the liquid inlet channel of the slurry inlet connector 1124. The slurry inlet seat 1125 is provided with two outlets, one of which is connected to the liquid inlet channel of the slurry inlet connector 1124 via a slurry inlet valve 1126, which is used to control the connection between the slurry inlet seat 1125 and the liquid inlet channel of the slurry inlet connector 1124. The other outlet can be connected to the liquid collection tank 18, and a residual slurry valve 1127 is provided between the two to control the connection between the other outlet and the liquid collection tank 18. In this embodiment, the slurry inlet valve 1126 and the residual slurry valve 1127 can be connected to the slurry inlet seat 1125 through a threaded joint, and the slurry inlet valve 1126 is connected to the slurry inlet connector 1124. The hose is connected to the residual slurry valve 1127 through the joint and then inserted into the liquid collection tank 18; the slurry inlet connector 1124 and the filter container 112 can be connected by a snap-fit ​​connection. Of course, the air passage can also be connected to the atmosphere by connecting a solenoid valve at the air inlet hole to control whether to allow the air inlet to enter or pressurize.

[0069] The working principle of the filter assembly is as follows: when work is required, the flap cylinder, i.e., the flap drive mechanism 116, extends to close the filter flap 113 in place, i.e., the filter flap 113 rotates in place, and the self-locking pneumatic clamp, i.e., the locking mechanism 115, extends to lock the filter flap 113; the residual slurry valve 1127 is closed, the slurry inlet valve 1126 is opened, and the pressure switch 1123 is opened to the atmosphere, or the solenoid valve at the air inlet is opened to the atmosphere; the slurry enters the filter container 112 through the slurry inlet seat 1125, the slurry inlet valve 1126, and the slurry inlet connector 1124. When the liquid level gauge detected by the liquid level sensor 1122 reaches the preset liquid level, the slurry inlet valve 1126 is closed, the residual slurry valve 125 is opened, and the slurry valve 125 is opened. The residual slurry flows out to the liquid collecting tank 18 through the residual slurry valve 125 and is discharged to the slurry pool; at the same time, the solenoid valve at the air inlet is actuated to pump the air pressure of the air compressor into the filter container 112, and the water in the filter container 112 is discharged into the liquid collecting tank through the filter drain trough 119 by positive pressure and discharged to the slurry pool; when the pressure in the filter container 112 begins to reach the preset pressure, the solenoid valve at the air inlet is actuated to connect the filter container 112 with the atmosphere, and at the same time, the self-locking pneumatic clamp and the flap cylinder are retracted in turn, and after the filter flap 113 is opened and in place, the filter flap 113 is rotated to the open state, and the cake air knives on both sides are opened to spray the cake to remove the entire cake and drop it into the filter trough 111.

[0070] See also Figures 8 and 9 , which shows the preferred structure of the cake drying assembly provided by the embodiment of the present utility model. As shown in the figure, the cake drying assembly 12 includes: a drying bracket 121, a drying drum 122, a drying mechanism 123 and a cake primary crushing mechanism 124; the drying drum 122 is rotatably arranged on the drying bracket 121, and the drying mechanism 123 is sleeved on the outer periphery of the drying drum 122, which is used to heat and dry the minerals in the drying drum 122 to obtain dried cake blocks. In order to improve the drying effect of the cake, preferably, a cake primary crushing mechanism 124 is provided at the inlet of the drying drum 122, which is used to perform primary crushing on the cake before the cake enters the inlet of the drying drum 122, and to feed the cake blocks obtained by the primary crushing into the drying drum 122 from the inlet of the drying drum 122.

[0071] Specifically, the drying bracket 121 plays a supporting role and can support the drying drum 122 and the drying mechanism 123. The drying drum 122 can be arranged on the drying bracket 121 at an angle, and the height of the inlet of the drying drum 122 is higher than the height of the outlet, that is, Figure 8The right end is shown to be higher than the left end so that the material in the drying drum 122 can move toward the discharge port under the action of gravity, and the material is dried by the drying drum 122 during the movement. The inlet and discharge port of the drying drum 122 can be rotatably supported on the drying bracket 121. To achieve the rotational drive of the drying drum 122, preferably, the drying drum 122 can be connected to a drum drive mechanism 125 for driving the drying drum 122 to rotate so that the material in the drying drum 122 rotates within the drying drum 122, so that the material is evenly dried, improving the drying efficiency, and also realizing the transportation of the material so that the material is output to the discharge port. In this embodiment, the discharge port of the drying drum 122 can be provided with a discharge blade (not shown in the figure) for controlling whether the dried cake is discharged. When the discharge blade rotates in a first predetermined direction, the dried cake can be discharged from the discharge port to the outside of the drying drum 122 to fall into the cake crushing assembly 13. When the discharge blade rotates in a second predetermined direction, the discharge of the dried cake is prevented. The first preset direction and the second preset direction are opposite directions, which are clockwise and counterclockwise respectively. For example, the discharge port of the drying cylinder 122 has two discharge blades distributed along the axial direction, or other numbers. When the discharge port of the drying cylinder 122 rotates axially, no drying cakes are discharged when it rotates clockwise, and the drying cakes are discharged when it rotates counterclockwise, thereby controlling the drying time of the material in the drying cylinder 122, thereby controlling the temperature and drying time, and achieving the drying requirements under the influence of different mineral types and different mineral particle sizes.

As shown, the cake crushing assembly 13 comprises a crushing shell 131, a crushing disk 132, and a crushing drive mechanism 133. The crushing disk 132 is rotatably disposed within the crushing shell 131 and is used to crush dried material blocks falling from the crushing shell 131, thereby breaking the dried material blocks into mineral powder.

The mineral powder is discharged from the crushing outlet channel 1313 and enters the mineral powder pressing component 14 to complete the crushing process.

[0086] See also Figures 13 to 16 , which illustrates the preferred structure of a mineral powder compacting assembly provided by an embodiment of the present invention. As shown in the figure, the mineral powder compacting assembly 14 comprises: a compacting support 141, a clamping drive mechanism 142, and a compacting drive mechanism 143. The clamping drive mechanism 142 is disposed on the compacting support 141, and a sample ring fixture 144 is provided at the power output end of the clamping drive mechanism 142 for securing or clamping a sample ring 17 capable of holding mineral powder. Driven by the clamping drive mechanism 142, the sample ring fixture 144 and the sample ring 17 are lifted and lowered, allowing the sample ring 17 to move to a loading position to receive mineral powder falling from the cake crushing assembly 13.

The clamping drive mechanism 142 and the pressing drive mechanism 143 are arranged along the same vertical line in the vertical direction. Moreover, the clamping drive mechanism 142 and the pressing drive mechanism 143 are arranged relative to each other so that the sample ring fixture 144 can move upward, that is, toward the pressing head 145, thereby driving the sample ring 17 upward to the loading position, so that the mineral powder falling from the cake crushing assembly 13 can fall into the sample ring 17. The pressing head 145 can move downward, that is, move closer to the sample ring fixture 144, to press the mineral powder in the sample ring 17. The pressing drive mechanism 143 can be a cylinder structure, used to drive the sample ring fixture 144 and sample ring 17 to move vertically up and down. The clamping drive mechanism 142 can also be a cylinder structure, arranged downward, used to drive the bottom pressure head 145 to move vertically up and down to press the mineral powder within the sample ring 17. In this embodiment, to control the pressed density of the solid cake, the pressing support 141 is preferably further provided with a residual powder scraping mechanism 146 for scraping excess cake powder from the sample ring 17, so that the sample ring 17 contains crushed mineral powder of the same size and height as the sample ring 17. This controls the volume of the crushed mineral powder before each pressing, thereby controlling the resulting solid cake. The thickness of the solid cake can be controlled by controlling the pressing drive mechanism 143.

[0088] Continue to see Figures 13 to 16 The pressing support seat 141 includes: a top plate 1411, two side plates 1412, a back plate 1413, a bottom plate 1414, a bracket 1415 and a front sealing plate 1416; the bottom plate 1414, the side plates 1412, the back plate 1413 and the top plate 1411 are assembled in sequence from bottom to top according to the space, the back plate 1413 is arranged vertically, and the two side plates 1412 are respectively arranged on the two vertical side edges of the back plate 1413; the top plate 1411 and the bottom plate 1414 are respectively arranged horizontally at the top and bottom ends of the back plate 1413 and the two side plates 1412, and the top of the two side plates 1412 is also provided with a front sealing plate 1416 arranged parallel to the back plate 1413, so that the top plate 1411, the two side plates 1412 and the front sealing plate 1416 can form a top working area to carry out loading and pressing in the top working area. The bracket 1415 is arranged on one side of the back plate 1413 facing away from the two side plates 1412 (eg Figure 13 The cake drying assembly 12 is fixedly mounted on a bracket 1415 via two side support plates 1212. The clamping drive mechanism 142 can be fixed to the top plate 1411, and the pressing drive mechanism 143 can be fixed to the bottom plate 1414.

[0089] Continue to see Figure 16A middle ring positioning plate 1417 may be provided on the pressing support seat 141, and a sample ring positioning hole (not shown in the figure) may be provided on the middle ring positioning plate 1417 for positioning the sample ring 17 so that the sample ring 17 moves to the sample ring positioning hole under the action of the clamping drive mechanism 142 to receive the mineral powder flowing out of the cake crushing assembly 13. Specifically, a middle ring positioning plate 1417 is provided at the middle height position of the pressing support seat 141, that is, between the clamping drive mechanism 142 and the pressing drive mechanism 143. The middle ring positioning plate 1417 can be installed at the bottom end of the top working area and can be fixed to the side plate by bolts to receive the mineral powder flowing out of the cake crushing assembly 13; and, the middle ring positioning plate 1417 is provided with a sample ring positioning hole directly above the clamping drive mechanism 142. The sample ring positioning hole can be a circular hole, so that the sample ring 17 moves upward to the sample ring positioning hole under the driving action of the clamping drive mechanism 142, that is, it is in the loading position. The loading position can be positioned through the sample ring positioning hole to ensure that the sample ring 17 is positioned at the loading position, thereby ensuring the stability of receiving the mineral powder and ensuring that the mineral powder can be received. A residual powder hole is also provided on the middle ring positioning plate 1417, which communicates with a residual powder channel 149. This allows excess powder on the sample ring 17 to be scraped off by a residual powder scraping mechanism 146 and into the residual powder hole and residual powder channel 149. In this embodiment, the press head 145, the sample ring positioning hole of the middle ring positioning plate 1417, and the sample ring fixture 144 are coaxially arranged, and this axis is arranged vertically.

[0090] Continue to see Figure 15 and Figure 16 The residual powder scraping mechanism 146 includes: a scraping pusher 1461 and a scraper 1462; the scraper 1462 is provided at the power output end of the scraping pusher 1461, and is used to perform reciprocating linear motion under the driving action of the scraping pusher 1461 to scrape off the excess cake powder in the sample ring 17. Specifically, the scraping pusher 1461 can be a scraping cylinder, and one end of the rod of the scraping cylinder (such as Figure 15 The right end shown in FIG. 1 is provided with a push plate 1463, which is provided on one side of the back plate 1413 (as shown in FIG. Figure 15 The push plate 1463 has guide shafts 1464 on both sides, and a linear bearing is installed on the back plate 1413. The front ends of the two guide shafts 1464 on the other side of the back plate 1413 (such as Figure 16 The guide shaft 1464, the scraper 1462 and the push plate 1463 move along the axial direction of the scraper cylinder as the scraper cylinder extends and retracts.

[0091] The working principle of the mineral powder pressing assembly is as follows: when the sample ring 17 is placed in the sample ring fixture 144, the pressing drive mechanism 143, i.e., the lower ring clamping cylinder, lifts the sample ring 17 and clamps it in the sample ring positioning hole of the middle ring positioning plate 1417, and the upper end surface of the sample ring 17 is flush with the upper surface of the middle ring positioning plate 1417; the crushed mineral powder flows into the sample ring 17, and when the crushing is completed, the scraping cylinder is activated, and the scraper 1462 scrapes the excess powder above the sample ring 17 to the residual powder channel 149. At this time, the sample ring 17 contains mineral powder that is the same size as the inner diameter of the sample ring 17 and the same height as the sample ring 17. After the mineral powder is at the same height as the sample ring 17, the pressing drive mechanism 143, that is, the upper pressing cylinder, descends, and after the mineral powder is compacted by the pressing head 145, the pressing drive mechanism 143 drives the pressing head 145 to retract to its original position.

[0111] See also Figure 25 、 Figures 26 to 28The preferred structure of the sample preparation device provided by an embodiment of the present invention is shown in the figure. As shown in the figure, the device includes: a filter assembly 11, a cake drying assembly 12, a cake crushing assembly 13, and a mineral powder pressing assembly 14. The filter assembly 11 is used to filter liquid from the ore slurry to form a mineral-containing filter cake; the cake drying assembly 12 is used to dry the mineral-containing filter cake to obtain a dried filter cake; the cake crushing assembly 13 is used to crush the dried filter cake to obtain mineral powder; and the mineral powder pressing assembly 14 is used to press the mineral powder into a sample cake for testing. The cake crushing assembly 13 includes a crushing shell 131, a crushing disk 132, a crushing drive mechanism 133, and a feeding mechanism 1340. The feeding mechanism 1340 is used to convey the dried filter cake to the crushing disk 132. The crushing disk 132 is rotatably disposed within the crushing shell 131 and is used to crush the dried material blocks conveyed by the feeding mechanism 1340 to form mineral powder. The crushing drive mechanism 133 is used to drive the crushing disk 132 to rotate.

[0112] Specifically, the filter assembly 11, the cake drying assembly 12 and the mineral powder pressing assembly 14 are arranged from top to bottom (relative to the Figure 25The filter assembly 11 is arranged in sequence as shown. The filter assembly 11 is arranged at the uppermost end and can be fixed on the first fixed base 15. The liquid inlet of the filter assembly 11 is located at the top to input the slurry and allow the slurry to flow downward to be filtered through the filter assembly 11, thereby filtering out the liquid in the slurry and achieving a stratified cake-like state with a high moisture content. The solid minerals in the slurry form a mineral-containing filter block, thereby obtaining a mineral-containing filter block. The mineral powder pressing assembly 14 is arranged at the lowest end and can be fixed on the second fixed machine base 16. There is a height difference between the filter assembly 11 and the mineral powder pressing assembly 14. The cake drying assembly 12 and the cake crushing assembly 13 are arranged between the filter assembly 11 and the mineral powder pressing assembly 14. The cake drying assembly 12 and the cake crushing assembly 13 can both be fixed on the mineral powder pressing assembly 14. In addition, the feeding end of the cake drying assembly 12 can extend into the interior of the filter assembly 11 to receive the mineral-containing filter block obtained by the filter assembly 11, and the mineral-containing filter block is dried by the cake drying assembly 12 to reduce the water content and form a dried filter block. The cake crushing assembly 13 is arranged below the cake drying assembly 12. The feeding port of the cake crushing assembly 13 is connected to the discharge port of the cake drying assembly 12, so that the dried filter block is crushed by the cake crushing assembly 13 to obtain mineral powder and achieve a uniform cake crushing state. The mineral powder pressing component 14 is arranged below the cake crushing component 13, and a sample ring 17 may be provided on the mineral powder pressing component 14 so that the mineral powder discharged from the discharge port of the cake crushing component 13 falls into the sample ring 17, and the mineral powder pressing component 14 presses the mineral powder in the sample ring 17 to obtain a sample cake, and then the element grade of the sample cake is detected. The element grade detection of the sample cake can be carried out by using existing conventional detection sensors, and the sample cake is indirectly detected in a non-contact manner to obtain the element grade of the slurry. Figure 25 As shown, the crushing shell 131 is located between the cake drying assembly 12 and the mineral powder pressing assembly 14 and can be fixed to the top of the mineral powder pressing assembly 14 via bolts. A crushing disc 132 and a feed mechanism 1340 are disposed within the crushing shell 131. The feed mechanism 1340 is located on one side of the crushing disc 132, while the other side of the crushing disc 132 is connected to the power output of the crushing drive mechanism 133. The crushing drive mechanism 133 drives the crushing disc 132 to rotate, thereby crushing the dried filter cake and producing mineral powder. The dried filter cake enters the feed mechanism 1340 through the feed port of the cake crushing assembly 13. The feed mechanism 1340 transports the dried filter cake to the crushing disc 132. Feeding mechanism 1340 eliminates the need to rely on the mineral powder's own gravity, thus ensuring the ability to transport low-density mineral powder and preventing low-density mineral powder from being unable to fall into the crushing disc 132 by gravity, which could cause material blockage in the feed channel.

[0113] In this embodiment, the first fixed base 15 and the second fixed base 16 serve as supports. They can be integral or separate, and this embodiment does not impose any limitations thereon. A liquid collection trough 18 is provided below the filter assembly 11 to drain the liquid filtered by the filter assembly 11. A drain pipe 19 is also connected to the liquid collection trough 18 to drain the liquid or other materials in the liquid collection trough 18 into the pulp tank.

[0114] By applying the above-mentioned technical solution of the present invention, the inflowing ore pulp is sampled by the sample preparation device 1 to convert the slurry into a sample cake to obtain a sample cake; the sample cake is transported to the pre-detection position on the side of the column element detection device by the transport device 2, and the element detection is performed on the sample cake by the element detection device 3. The cake crushing component 13 in the sample preparation device 1 crushes the dried filter block to obtain mineral powder, and the mineral powder pressing component 14 presses the mineral powder into a sample cake for detection. The cake crushing component 13 conveys the dried filter block to the crushing disk 132 for crushing processing through the feeding mechanism 1340, without relying on gravity, thereby ensuring the conveying capacity of low-density mineral powder and preventing the low-density mineral powder from falling into the crushing disk 132 by gravity, causing the occurrence of material pile-up and blockage in the feed channel. This not only ensures the normal operation of the equipment, but also helps to improve the detection efficiency.

The screw feeder is located below the feed port of the crushing shell 131, and the crushing disk 132 is located above the discharge port of the crushing shell 131. The feeding drive assembly can drive the screw feeder to rotate to transport the dried filter blocks entering through the feed port of the crushing shell 131 to the crushing disk 132. The crushing shell 131 is a horizontally arranged shell structure. The feed and discharge ports of the crushing shell 131 are arranged horizontally at both ends of the crushing shell 131, so that the feed and discharge ports of the crushing shell 131 are separated by a certain distance. The screw feeder and the crushing disk 132 are arranged in sequence along the direction from the feed port to the discharge port. The feeding drive assembly includes a screw conveying motor 1341. The drive shaft of the screw conveying motor 1341 is connected to the screw feeder through a conveying motor bearing 1342. The screw feeder drives the screw feeder to rotate and squeeze the dried filter cake into the crushing disk 132, thereby effectively preventing material from accumulating at the feed port and causing material blockage.

The sample ring fixture 144 is used to clamp a sample ring 17 that can hold mineral powder. Under the driving action of the clamping drive mechanism 142, the sample ring fixture 144 and the sample ring 17 perform a lifting movement so that the sample ring 17 can move to the loading position to receive the mineral powder falling from the cake crushing assembly 13. The sample ring fixture 144 is provided with a sample ring detection switch 148 for detecting the sample ring 17; the pressing drive mechanism 143 is arranged on Above the clamping drive mechanism 142, a pressure head 145 is provided at the power output end of the pressing drive mechanism 143. This head is used to move toward the sample ring 17 under the drive of the pressing drive mechanism 143 to press the mineral powder in the sample ring 17 to obtain a sample cake. A residual powder scraping mechanism 146 is provided on the pressing support seat 141 and is used to scrape off excess mineral powder on the sample ring 17 so that the sample ring 17 contains mineral powder that is equal in size and height to the inner diameter of the sample ring 17. A residual material removal member 147 is provided on the pressing support seat. The residual material removal member 147 has multiple air holes. The residual material removal member 147 sprays air toward the sample cake through the multiple air holes to blow away excess mineral powder, ensuring the cleanliness of the surface of the sample cake and the sample ring 17, while reducing dust accumulation during the transportation of the sample ring 17. Specifically, the pressing support seat 141 plays a supporting role and can support the clamping drive mechanism 142 and the pressing drive mechanism 143 as well as the cake drying assembly 12 and the cake crushing assembly 13.

This allows the mineral powder falling from the cake crushing assembly 13 to fall into the sample ring 17. The pressing head 145 can then move downward, i.e., toward the sample ring fixture 144, to press the mineral powder within the sample ring 17. To control the pressed density of the sample cake, the pressing support 141 is preferably provided with a residual powder scraping mechanism 146 for scraping excess cake powder from the sample ring 17, ensuring that the sample ring 17 contains mineral powder equal in size and height to the inner diameter of the sample ring 17. This allows the volume of the mineral powder before each pressing cycle to be controlled, thereby controlling the thickness of the resulting sample cake. The thickness of the sample cake can be controlled by controlling the pressing drive mechanism 143. In this embodiment, a residual material removing member 147 is provided to blow the sample cake after compaction to remove excess mineral powder and ensure the quality of the sample cake.The sample ring detection switch 148 is used to detect whether the sample ring 17 is placed on the sample ring fixture 144. When it is detected that the sample ring 17 is located on the sample ring fixture 144, the clamping drive mechanism 142 drives the sample ring fixture 144 and the sample ring 17 to move up and down, so that the sample ring 17 can move to the loading position to receive the mineral powder falling from the cake crushing assembly 13.

[0124] In summary, the online slurry multi-element grade analysis system provided in this embodiment uses a sample preparation device 1 to prepare a sample of the incoming slurry to convert the slurry into a solid cake to obtain a solid cake; the solid cake is transported to the pre-detection position on the side of the element detection device 3 by the transport device 2, and the element detection device 3 performs element detection on the solid cake. Non-contact detection can be used, and there is no need to perform direct contact detection through the detection window. At the same time, the elements of the solid cake will not contaminate the detection window, avoiding contamination and wear of the detection window, solving the problem of low detection accuracy caused by the existing grade meter detection of elements in direct contact with the slurry. At the same time, since the direct target sample for detection is a solid cake, and the preparation of the solid cake is not affected by the concentration, it indirectly ensures that the system has high accuracy and stability. The solid cake is not affected by the slurry concentration, thereby improving the accuracy of the detection results. Therefore, the system can detect multiple element grades at the same time, with high detection accuracy and is not affected by the slurry concentration. The key components are not contaminated or worn, have a long service life, and are easy to maintain.
