[0098] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the disclosure to those skilled in the art. It should be noted that, unless otherwise specified, embodiments and features of the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0099] See Figure 1 As shown, this is a preferred structure of the slurry grade detection system provided in this embodiment of the present invention. As shown, the system includes: a sample preparation device 1, a transport device 2, and an element detection device 3; the sample preparation device 1 is used to prepare a solid sample from the incoming slurry, transforming the slurry into a sample cake; the transport device 2 is used to transport the sample cake to a pre-detection position; the element detection device 3 is used to perform element detection on the sample cake located at the pre-detection position to obtain the element grade in the sample cake, and thus obtain the element grade in the slurry.

[0100] Specifically, the element detection device 3 and the sample preparation device 1 are installed side by side on the base frame 4. When facing the plane of the integrated control unit for 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, close to it. 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 base frame 4 (e.g., Figure 1 As shown, the left and right sides along the X direction), and the pre-detection position is located on the side where the element detection device 3 is located (e.g., the left and right sides along the X direction). Figure 1 (As shown on the left). The transport device 2 can be mounted on the base frame 4 to transport the sample cake prepared by the sample preparation device 1 to the pre-detection position on the side where the elemental detection device 3 is located, so that the elemental detection device 3 can perform elemental detection on the sample cake. In this embodiment, the elemental detection device 3 can use X-ray fluorescence to perform non-contact elemental detection on the sample cake. Figure 1 As shown, in this embodiment, there are two sample preparation devices 1. Of course, there can also be one or three, or other quantities of sample preparation devices 1. In this embodiment, the number of sample preparation devices 1 is not limited. For example, as Figure 2 As shown, multiple sample preparation devices 1 are arranged in a straight line. In this embodiment, an electromagnetic automatic double-opening door 5 may also be provided between the element detection device 3 and the sample preparation device 1. This door is used to open when the transport device 2 transports the sample cake, so that the transport device 2 can transport the sample cake from the electromagnetic automatic double-opening door 5 to the detection station and close and seal the element detection device 3 to prevent radiation from the element detection device 3.

[0101] In alternative embodiments, such as Figure 3 As shown, there are multiple sample preparation devices 1, which are distributed around the element detection device 3. By setting up multiple sample preparation devices 1 to provide sample cakes to the element detection device 3, it is beneficial to improve the detection efficiency.

[0102] like Figure 2 to Figure 4 As shown, in an optional embodiment, the handling device 2 can be a handling robot or a robotic arm. When multiple sample preparation devices 1 are arranged in a straight line, a robot with a large arm span can be used. Of course, a robot with a telescopic arm can also be used. Using a handling robot can not only reduce labor costs and improve detection efficiency, but also improve the automation level of the slurry grade detection system, so as to facilitate the automated control of the slurry grade detection system. For example, the handling robot can be a handling robot with a gripper robotic arm. Of course, the handling device 2 includes, but is not limited to, handling robots with gripper robotic arms.

[0103] like Figure 4As shown, when multiple sample preparation devices 1 are arranged along a straight line, a linear guide rail can also be set below the transport robot to ensure the movement direction of the transport robot.

[0104] See Figure 5 , Figure 12 to Figure 14 As shown, this utility model provides a preferred structure for a sample preparation device. The device includes a filtration assembly 11, a drying assembly 12, a crushing assembly 13, and a pressing assembly 14. The filtration assembly 11 filters out liquid from the slurry to form mineral-containing filter blocks. The drying assembly 12 dries the mineral-containing filter blocks to obtain dried filter blocks. The crushing assembly 13 crushes the dried filter blocks to obtain mineral powder. The pressing assembly 14 presses the mineral powder into sample cakes for testing. The crushing assembly 13 includes a crushing shell 131, a crushing disc 132, a crushing drive mechanism 133, and a feeding mechanism 134. The feeding mechanism 134 conveys the dried filter blocks to the crushing disc 132. The crushing disc 132 is rotatably disposed inside the crushing shell 131 to crush the dried material blocks conveyed by the feeding mechanism 134, thereby crushing the dried material blocks to form mineral powder. The crushing drive mechanism 133 drives the crushing disc 132 to rotate.

[0105] Specifically, the filter assembly 11, drying assembly 12, and pressing assembly 14 are arranged from top to bottom according to their spatial height (relative to...). Figure 5(As shown in the diagram) arranged sequentially. The filter assembly 11 is located at the top and can be fixed to the first fixed base 15. The inlet of the filter assembly 11 is located at the top to input the slurry, allowing the slurry to flow downwards and pass through the filter assembly 11 for filtration. This removes the liquid from the slurry, resulting in a slurry with initially high moisture content and a layered cake state, allowing the solid minerals in the slurry to form mineral-containing filter blocks. The pressing assembly 14 is located at the bottom and can be fixed to the second fixed base 16. The filter assembly 11 and the pressing assembly 14 have a height difference. The drying assembly 12 and the crushing assembly 13 are arranged between the filter assembly 11 and the pressing assembly 14. Both the drying assembly 12 and the crushing assembly 13 can be fixed to the pressing assembly 14. Furthermore, the feed end of the drying assembly 12 can extend into the interior of the filter assembly 11 to receive the mineral-containing filter blocks obtained by the filter assembly 11 and dry the mineral-containing filter blocks through the drying assembly 12 to reduce the moisture content, thus forming dried filter blocks. The crushing component 13 is positioned below the drying component 12. The inlet of the crushing component 13 is connected to the outlet of the drying component 12, allowing the crushing component 13 to crush the dried filter blocks, obtaining mineral powder and achieving a uniformly pulverized cake. The pressing component 14 is positioned below the crushing component 13, and may be equipped with a sample ring 17. This allows the mineral powder discharged from the outlet of the crushing component 13 to fall into the sample ring 17, where the pressing component 14 presses the powder to obtain a sample cake. The elemental grade of the sample cake can then be detected using existing conventional sensors in a non-contact, indirect manner to obtain the elemental grade of the slurry. Figure 5 As shown, the crushing housing 131 is located between the drying assembly 12 and the pressing assembly 14, and can be fixed to the top of the pressing assembly 14 by bolts. The crushing disc 132 and the feeding mechanism 134 are disposed inside the crushing housing 131, with the feeding mechanism 134 located on one side of the crushing disc 132. The other side of the crushing disc 132 is connected to the power output end of the crushing drive mechanism 133. The crushing drive mechanism 133 can drive the crushing disc 132 to rotate, thereby crushing the dried filter blocks to obtain mineral powder. The dried filter blocks enter the feeding mechanism 134 through the feed inlet of the crushing assembly 13. The feeding mechanism 134 conveys the dried filter blocks to the crushing disc 132. The feeding mechanism 134 does not rely on the gravity of the mineral powder itself, thus ensuring the conveying capacity for low-density mineral powder and preventing low-density mineral powder from falling into the crushing disc 132 by gravity, which could cause material accumulation and blockage in the feed channel.

[0106] In this embodiment, the first fixed base 15 and the second fixed base 16 serve a supporting function. They can be an integral structure or two independent fixed bases; no limitation is made in this embodiment. A liquid collection tank 18 is also provided below the filter assembly 11 to allow the liquid filtered out by the filter assembly 11 to drain into the liquid collection tank 18. A drain pipe 19 may also be connected to the liquid collection tank 18 for draining the liquid or other materials in the liquid collection tank 18 into the slurry tank.

[0107] Applying the above-mentioned technical solution of this utility model, the sample preparation equipment 1 prepares the incoming slurry to transform the slurry into a sample cake. The sample cake is then transported to the pre-detection position on the side of the elemental detection equipment by the conveying equipment 2, and the elemental detection equipment 3 performs elemental detection on the sample cake. The crushing component 13 in the sample preparation equipment 1 crushes the dried filter block to obtain mineral powder. The pressing component 14 presses the mineral powder into a sample cake for detection. The crushing component 13 conveys the dried filter block to the crushing disc 132 for crushing via the feeding mechanism 134, eliminating the need for gravity. This ensures the conveying capacity for low-density mineral powder and prevents it from falling into the crushing disc 132 due to gravity, thus avoiding material blockage in the feed channel. This not only ensures the normal operation of the equipment but also improves detection efficiency.

[0108] See Figure 12 , 13 As shown in Figure 14, in this embodiment, the feeding mechanism 134 includes a screw feeder and a feeding drive assembly. The crushing shell 131 is provided with an inlet and an outlet at intervals along its length. The screw feeder and the crushing disc 132 are disposed inside the crushing shell 131. The screw feeder is located below the inlet of the crushing shell 131, and the crushing disc 132 is located above the outlet of the crushing shell 131. The feeding drive assembly can drive the screw feeder to rotate so as to transport the dried filter blocks that enter through the inlet of the crushing shell 131 to the crushing disc 132. The crushing shell 131 is a horizontally arranged shell structure. The inlet and outlet of the crushing shell 131 are horizontally arranged at both ends, with a certain distance between them. The screw feeder and the crushing disc 132 are arranged sequentially from the inlet to the outlet. The feeding drive assembly includes a screw conveyor motor 1341. The drive shaft of the screw conveyor motor 1341 is connected to the screw feeder through a conveyor motor bearing 1342, driving the screw feeder to rotate and compress the dried filter blocks into the crushing disc 132, thereby effectively preventing material accumulation at the inlet and avoiding material blockage. In this embodiment, the conveyor motor bearing 1342 is mounted on one side of the crushing shell 131 through a screw bearing seat 1343. The screw conveyor motor 1341 is covered by a screw motor protective cover 1344 to protect it.

[0109] See Figure 12 As shown, in this embodiment, the screw feeder includes a conveying shaft 1345 and screw blades 1346 mounted on the conveying shaft 1345. The screw blades 1346 are arranged along the axial direction of the conveying shaft 1345. The crushing disc 132 is provided with a plurality of crushing blades 1321 on the side near the screw feeder. Each crushing blade is located above the discharge port of the crushing housing 131. The crushing drive mechanism 133 includes a crushing motor 1331, a crushing motor base 1332, a coupling 1333, a crushing motor bearing 1334, and a coupling cover 1335. The crushing motor 1331 is mounted on the outside of the crushing housing 131 through the crushing motor base 1332. The output shaft of the crushing motor 1331 is connected to the coupling 1333. The coupling 1333 is connected to the crushing disc 132 through the crushing motor bearing 1334. The coupling 1333 is covered by a coupling cover 1335 to protect the coupling 1333. Specifically, when the dried filter blocks discharged from the drying assembly 12 enter the feed inlet of the crushing shell 131, they are squeezed by the spiral blades 1346 and conveyed to the crushing disc 132. The crushing disc 132 rotates, driving the crushing blades 1321 to rotate and crush the dried filter blocks to obtain mineral powder. The mineral powder is discharged from the discharge outlet of the crushing shell 131 below the crushing blades 1321 and enters the pressing assembly 14 to complete the crushing process.

[0110] See Figure 6 to Figure 9 As shown, in this embodiment, the filter assembly 11 includes a filter base 111, a filter container 112, a pneumatic control assembly, a metering device, and a filter plate 113. The filter container 112 is disposed on the filter base 111, and has an inlet and an outlet at its upper and lower ends, respectively. The inlet of the filter container 112 is connected to the metering device, which controls the amount of slurry injected into the filter container 112. The pneumatic control assembly is connected to the filter container 112 and is used to control the pressure inside the filter container 112. The filter plate 113 has filter holes (not shown in the figure) for liquid to flow out, and is movably disposed below the outlet of the filter container 112. The filter plate 113 can open or close the outlet of the filter container 112. Specifically, the filter base 111 serves as a support to support the filter container 112 and the filter plate assembly. The top plate of the filter base 111 has a flap clearance hole. The filter container 112 is positioned above the filter base 111, and the outlet of the filter container 112 extends from the flap clearance hole into the interior of the filter base 111. The inlet at the top of the filter container 112 is a liquid inlet 1121, used to inject slurry into the filter container 112. The filter plate 113 has an open state and a closed state, such as... Figure 6As shown, in the closed state, the filter plate 113 blocks the outlet of the filter container 112. The filter plate 113 is provided with filter holes, so that the liquid in the slurry can flow out from the filter holes and be discharged into the collection tank 18, and then discharged into the slurry pool through the drain pipe 19. The solid minerals in the slurry remain on the filter plate 113 to form mineral-containing filter blocks. When the filter plate 113 is in the open state, the filter plate 113 is in the open position, the outlet of the filter container 112 is unobstructed, and the mineral-containing filter blocks can fall from the filter plate 113 into the drying assembly 12.

[0111] See Figure 7 and Figure 8As shown, in this embodiment, the metering device includes a metering cylinder (not shown in the figure) and a level sensor 1122. The metering cylinder is connected to the inlet of the filter container 112 and is used to hold a preset injection volume of slurry. The level sensor 1122 is installed on the filter container 112 and is used to detect the slurry level in the filter container. The pneumatic control component includes an air compressor (not shown in the figure) and a pneumatic control box 1126. The air compressor is connected to the pneumatic control box 1126 and the filter container 112. Specifically, the metering cylinder is a barrel with a preset volume, used to hold slurry and supply slurry to the filter container 112. The level sensor 1122 can be an electronic level gauge, used to detect the slurry level in the filter container 112, so that when the slurry level in the filter container 112 reaches the preset level, the input of slurry to the filter container 112 is terminated, thereby controlling the slurry input to the filter container 112 before filtration. The slurry is metered into the filter container 112 by a metering cylinder, and the level of the injected slurry is detected by a level sensor 1122, thus providing a precise metered supply of slurry. A pressure switch 1123 is also provided on the filter container 112 to detect the pressure inside the filter container 112. When the pressure inside the filter container 112 reaches or exceeds a preset pressure, the switch opens, connecting the filter container 112 to the outside atmosphere, thereby controlling the filtration state within the filter container 112 to avoid insufficient or excessive filtration of the cake. A slurry inlet connector 1124 is connected to the liquid inlet 1121, which has three connecting channels: a gas channel, a liquid level measurement channel, and a liquid inlet channel, each connected to the filter container 112. The level sensor 1122 is mounted on the slurry inlet connector 1124, passing through the liquid level measurement channel and extending into the filter container 112 to detect the slurry level inside the filter container 112. A pressure switch 1123 is mounted on the side wall of the slurry inlet connector 1124 and is connected to the gas channel. It measures the pressure in the gas channel, the liquid inlet 1121, and the filter container 112, and controls the flow between the atmosphere and the gas channel. An air inlet 11241 is also provided on the side wall of the slurry inlet connector 1124, which is connected to the gas channel. The air inlet 11241 may be equipped with an air inlet connector for connecting an air compressor to provide air pressure (i.e., pressurize) into the filter container 112. The air compressor is also connected to an air control box 1126, which is mounted on the filter base 111 and controls the air compressor to provide air pressure into the filter container 112. A three-way valve 1125 is also connected to the liquid inlet channel of the slurry inlet connector 1124. Of the other two outlets of the three-way valve 1125, one outlet is connected to a metering device, and the other outlet is connected to a collection tank 18.

[0112] See Figure 6 to Figure 9As shown, in this embodiment, the filter assembly 11 further includes a rejection assembly 114 and a locking assembly 115. The rejection assembly 114 includes a rejection mechanism 1141 and a rejection mechanism dust cover 1142 for covering the rejection mechanism 1141. The rejection mechanism 1141 is disposed on the filter base 111 and located on one side of the filter plate 113, and is used to reject the mineral-containing filter blocks on the filter plate 113 so that they fall into the drying assembly 12. The locking assembly 115 includes a locking mechanism 1151 and a locking dust cover 1152 for covering the locking mechanism 1151.

[0113] In this embodiment, to ensure that the mineral-containing filter blocks can fall from the filter plate 113 into the drying assembly 12, two rejection mechanisms 1141 are provided, respectively disposed on both sides of the filter plate 113. Of course, one or more rejection mechanisms 1141 can be used, and this is not limited. In this embodiment, the rejection mechanism 1141 can be a cake-shaped air knife, which can be inclined and arranged parallel to the filter plate 113 in the open state. When the filter plate 113 is rotated to the open state, it blows the mineral-containing filter blocks off, that is, when the filter plate 113 is in the open state, it sprays air onto the mineral-containing filter blocks on the filter plate 113, applying a blowing force to the mineral-containing filter blocks so that they fall off the filter plate 113 and into the drying assembly 12. Of course, in other embodiments, the rejection mechanism 1141 can also be other rejection mechanisms, such as a scraping mechanism, used to apply a scraping force to the cake to make the cake fall. When air-knife blows through the mineral-containing filter blocks, dust may overflow from the gaps in the structural components. A dust cover 1142 for the discarding mechanism is installed to prevent this overflow. The dust cover 1142 can be made of sheet metal welded or stamped, or it can be integrally machined and installed by screwing it to the main body. Furthermore, the dust cover 1142 can have pneumatic or electric transition joints required for the mechanism's operation, facilitating structural maintenance.

[0114] In this embodiment, the filter base 111 is also provided with a locking assembly 115. The locking assembly 115 includes a locking mechanism 1151 and a locking dust cover 1152. The locking mechanism 1151 is used to lock the filter plate 113 onto the filter base 111 when the filter plate 113 is in the closed state, so as to ensure the stability of the filter plate 113 in sealing and filtering. Specifically, the locking assembly 115 includes a locking mechanism 1151, and there can be two locking mechanisms 1151, which are respectively arranged on both sides of the filter plate 113 (relative to the filter base 113). Figure 8(As shown in the diagram) is used to lock and release the filter plate 113. When the filter plate 113 is in the closed state, it is locked along with the filter plate 113. After filtration is completed, the filter plate 113 can be released so that it can be rotated to the open state. This allows the mineral-containing filter block to fall along the top wall of the filter plate 113 under the action of blowing or scraping, and then fall downward under the limiting action of the side plate of the filter base 111. The locking mechanism 1151 can be a self-locking pneumatic gripper to clamp the filter plate 113 in the closed state, thereby realizing the pressure locking and release of the filter plate 113. Of course, the filter plate 113 can also be other locking structures, and no limitation is made in this embodiment. The locking dust cover 1152 is provided on the exposed part of the locking mechanism 1151 to prevent dust from overflowing from the filter assembly 11. Optionally, the locking dust cover 1152 includes a dustproof shell and a dustproof brush disposed in the dustproof shell.

[0115] See Figure 6 As shown, the filter plate 113 can also be connected to a filter plate drive mechanism 116, which is used to drive the filter plate 113 to rotate so that the filter plate can switch states. Specifically, the filter base 111 can be provided with a filter plate pin seat 117, and the fixing seat of the filter plate drive mechanism 116 can also be installed on the filter base 111. Both the filter plate pin seat 117 and the fixing seat of the filter plate drive mechanism 116 can be fixed to the filter base 111 by bolts or other connecting parts. The power output end of the filter plate drive mechanism 116 can pass through the top plate of the filter base 111 and extend into the interior of the filter base 111. The power output end of the filter plate drive mechanism 116 is provided with a connecting ear 118. The filter plate pin seat 117 can also be provided with a connecting ear 118 located inside the filter base 111. The connecting ear on the filter plate pin seat 117 is located between the opening end of the filter container 112 and the connecting ear on the filter plate drive mechanism 116. The filter plate 113 is rotatably connected to the connecting ear on the filter plate pin seat 117 and the connecting ear on the filter plate drive mechanism 116 through a pin shaft. Under the driving action of the power output end of the filter plate drive mechanism 116, the filter plate 113 is driven to rotate around the connecting ear on the filter plate pin seat 117 to realize the switching of states. The filter plate drive mechanism 116 can be a flap cylinder structure with its power output end facing downwards. It is used to push the left end of the filter plate 113 to move up and down, so that the filter plate 113 can rotate around the connecting lug on the filter plate pin seat 117. That is, when filtration is required, the power output end of the flap cylinder structure, i.e. the filter plate drive mechanism 116, extends out, and the filter plate 113 is closed and rotated to the closed state. After filtration is completed, the power output end of the flap cylinder structure, i.e. the filter plate drive mechanism 116, retracts, and the filter plate 113 is opened and rotated to the open state.

[0116] See Figure 6As shown, in this embodiment, a filter drain trough 119 is provided below the filter plate 113 to collect the liquid flowing down from the filter plate 113. Specifically, the filter drain trough 119 is installed below the top plate of the filter base 111, and the filter drain trough 119 can also be installed below the filter plate 113, swinging with the swinging of the filter plate 113. In this embodiment, the filter drain trough 119 can be connected to a drain pipe, and its outlet can be set in the collection tank 18, so that the water in the filter container 112 is discharged into the collection tank 18 through the guide of the filter drain trough 119 and the drain pipe by positive pressure, and then discharged into the slurry tank.

[0117] See Figure 6 and Figure 9 As shown, in this embodiment, a filter material trough 1111 is also provided on the filter base 111 below the filter plate 113, so that the filter cake falls into the filter material trough 1111 and falls into the drying assembly 12 under the guidance of the filter material trough 1111. Specifically, the filter material trough 1111 is arranged inside the filter base 111. The mineral-containing filter block can fall along the top wall of the filter plate 113 under the action of blowing or scraping, and fall downward into the filter material trough 1111 under the limiting action of the side plate of the filter base 111. The discharge port of the filter material trough 1111 can be arranged downward so that the mineral-containing filter block falls into the drying assembly 12 under the action of gravity.

[0118] The working principle of this filter assembly is as follows: When operation is required, the flap cylinder, i.e., the filter plate drive mechanism 116, extends to close the filter plate 113 to its final position, i.e., the filter plate 113 rotates to its final position. Then, the self-locking pneumatic gripper, i.e., the locking mechanism 1151, extends to lock the filter plate 113. The outlet of the three-way valve 1125, connected to the metering cylinder, opens, and the pressure switch 1123 opens to allow atmospheric air to pass through, or the solenoid valve at the air inlet opens to allow atmospheric air to pass through. The slurry enters the filter container 112 through the three-way valve 1125 and the slurry inlet connector 1124. When the level sensor 1122 detects that the level gauge has reached the preset level, the outlet of the three-way valve 1125, connected to the collection tank 18, opens, and excess slurry passes through the three-way valve 1125. The liquid flows out through valve 1125 to collection tank 18 and is discharged into slurry tank; at the same time, the solenoid valve at the air inlet is activated, and the air is compressed by the air compressor into the filter container 112. The water in the filter container 112 is discharged into the collection tank through the filter drain trough 119 and discharged into slurry tank through the positive pressure; when the pressure in the filter container 112 begins to reach the preset pressure, the solenoid valve at the air inlet is activated to connect the filter container 112 with the atmosphere. At the same time, the self-locking pneumatic gripper and the flip-plate cylinder retract in sequence. After the filter plate 113 is opened, the filter plate 113 rotates to the open state, and the air knives on both sides of the cake block open to spray out the ore-containing filter block, so as to remove the entire cake and let it fall into the filter material tank 1111.

[0119] See Figure 10 to Figure 11As shown, the drying assembly 12 in this embodiment includes: a drying support 121, a drying cylinder 122, a drying mechanism 123, and a primary crushing mechanism 124. The drying cylinder 122 is rotatably mounted on the drying support 121, and the drying mechanism 123 is fitted around the outer periphery of the drying cylinder 122 for heating and drying the minerals inside the drying cylinder 122 to obtain dried filter blocks. To improve the drying effect on the filter cake, preferably, a primary crushing mechanism 124 is provided at the inlet of the drying cylinder 122 for primary crushing of the filter cake before it enters the inlet of the drying cylinder 122, and the filter cake obtained from the primary crushing is fed into the drying cylinder 122 from the inlet of the drying cylinder 122.

[0120] See Figure 10 As shown, in this embodiment, the drying assembly 12 includes a drying support 121, a drying cylinder 122, a drying mechanism 123, a primary crushing mechanism 124, a cylinder driving mechanism 125, and a baffle mechanism 126. The drying cylinder 122 is rotatably mounted on the drying support 121, and the drying mechanism 123 is provided on the drying cylinder 122 for heating and drying the minerals inside the drying cylinder 122. The cylinder driving mechanism 125 is used to drive the drying cylinder 122 to rotate. The drying cylinder 122 has an inlet and a outlet. The primary crushing mechanism 124 is located at the inlet of the drying cylinder 122 and is used to perform primary crushing on the mineral-containing filter blocks and feed the crushed mineral-containing filter blocks into the drying cylinder 122. The baffle mechanism 126 is located at the outlet of the drying cylinder 122 and is used to block or release the dried filter blocks inside the drying cylinder 122. Specifically, the drying support 121 provides support for the drying cylinder 122 and the drying mechanism 123. The drying cylinder 122 can be arranged at an incline on the drying support 121, and the height of the inlet of the drying cylinder 122 is higher than the height of the outlet, i.e. Figure 10 The right end is higher than the left end, so that the material inside the drying cylinder 122 can move towards the discharge port under gravity and be dried by the drying cylinder 122 during the movement. Both the inlet and outlet of the drying cylinder 122 are rotatably supported on the drying support 121. Preferably, to drive the rotation of the drying cylinder 122, a cylinder drive mechanism 125 is connected to drive the drying cylinder 122 to rotate, so that the material inside the drying cylinder 122 rotates, resulting in uniform drying and improved drying efficiency. It also facilitates material conveying, allowing the material to be output to the discharge port. In this embodiment, the discharge port of the drying cylinder 122 may be equipped with a baffle mechanism 126 to block or release the drying filter blocks inside the drying cylinder 122, preventing leakage and insufficient sample cake quantity. Simultaneously, it controls the drying time of the material inside the drying cylinder 122, thereby controlling the temperature and drying duration to meet the drying requirements under the influence of different mineral types and particle sizes.

[0121] SeeFigure 10 As shown, in this embodiment, the drying mechanism 123 is sleeved on the outer periphery of the drying cylinder 122, and the drying mechanism 123 can be fixed on the drying support 121. It can heat the drying cylinder 122 to achieve heating and drying of the material inside the drying cylinder 122. The primary crushing mechanism 124 is set at the feed inlet of the drying cylinder 122, and part of it can extend into the filter trough 1111 to crush the material cake falling into the filter trough 1111. The crushed cake can be fed into the drying cylinder 122 from the feed inlet of the drying cylinder 122 for drying by the drying mechanism 123.

[0122] See Figure 10 and Figure 11 As shown, in this embodiment, the drying bracket 121 includes a base plate 1211, two side support plates 1212, and two support bearing plates 1213. The two side support plates 1212 are spaced apart, and the base plate 1211 is inclined between the two side support plates 1212. The two sides of the base plate 1211 are respectively connected to the two side support plates 1212 to form a fixed support frame. Specifically, the base plate 1211 is inclined, and the two side support plates 1212 are vertically arranged on both sides of the base plate 1211 to provide vertical support. The bottom ends of both side support plates 1212 can each extend with a connecting plate arranged at an angle to the side support plates 1212 for mounting on the pressing assembly 14. The top ends of both side support plates 1212 can be fixed to the base plate 1211 by welding or other means. The two support bearing plates 1213 are respectively arranged on the other two sides of the base plate 1211 (e.g., ...). Figure 10 The left and right sides (as shown) are used to provide rotational support for the inlet and outlet of the drying cylinder 122, respectively. Of course, the number of support bearing plates 1213 can also be other, such as one or three; this embodiment does not impose any limitation. In this embodiment, the bottom end of the support bearing plate 1213 can be fixed to the base plate 1211 by welding or other fixing methods. A bearing can be provided between the support bearing plate 1213 and the inlet or outlet of the drying cylinder 122, so that the drying cylinder 122 can rotatably pass through the support bearing plate 1213 and can realize the rotation of the drying cylinder 122.

[0123] See Figure 10 to Figure 11As shown, in this embodiment, the drying mechanism 123 includes a coil sleeve 1231 and a heating coil 1232. The coil sleeve 1231 is sleeved on the outer periphery of the drying cylinder 122, and the heating coil 1232 is provided on the coil sleeve 1231 for heating the coil sleeve 1231, so that the coil sleeve 1231 heats and dries the material inside the drying cylinder 122. Specifically, the coil sleeve 1231 is fixedly supported above the drying bracket 121. In this embodiment, the coil sleeve 1231 can be fixed to the drying bracket 121 by a coil support plate 1233. The top of the coil support plate 1233 can be sleeved on the outer periphery of the coil sleeve 1231 to support the coil sleeve 1231, and the bottom end can be fixed to the base plate 1211 by bolts, or it can be fixed by other means.

[0124] See Figure 10As shown, in this embodiment, the primary crushing mechanism 124 includes a feed trough 1241, a primary crushing body 1242, a conveyor 1243, and a dividing wheel 1244. The feed trough 1241 is located at the feed inlet of the drying cylinder 122, and the primary crushing body 1242 is located at the feed inlet of the feed trough 1241. The primary crushing body 1242 and the drying cylinder 122 are connected by a linkage assembly, which includes a primary transmission component 1245 and a secondary transmission component 1246. The primary transmission component 1245 is located on the drying cylinder 122, and the secondary transmission component 1246 is connected to the power input end of the primary crushing body 1242. Rotation of the drying cylinder 122 drives the primary transmission component 1245 to rotate, which in turn drives the secondary transmission component 1246 to rotate, and the secondary transmission component 1246 drives the primary crushing body 1242 to rotate. The conveyor 1243... 243 is disposed in the feed trough 1241 and located below the primary crushing body 1242. The conveying component 1243 is also connected to the drying cylinder 122 and is used to rotate synchronously with the drying cylinder 122 to convey the material blocks that fall after primary crushing of the primary crushing body 1242 from the feed inlet of the drying cylinder 122 into the drying cylinder 122. The dividing wheel 1244 is disposed at the feed inlet of the drying cylinder 122 and is used to divide the feed inlet of the drying cylinder 122 into sections. The cylinder drive mechanism 125 includes a power motor 1251, a power wheel 1252 and a transmission belt 1253. The power motor 1251 is mounted on the drying support 121 through a motor support 1254. The power wheel 1252 is disposed on the output shaft of the power motor 1251. The power wheel 1252 is connected to the drying cylinder 122 through the transmission belt to realize rotation input. Specifically, the feed trough 1241 is used to collect the slag from the primary crushing body 1242, preventing the slag from falling and affecting the operation of other components. The primary crushing body 1242 is rotatably disposed above the feed inlet of the feed trough 1241, and can extend into the filter trough 1111 to crush the mineral-containing filter blocks in the filter trough 1111. The feed trough 1241 is located directly below the discharge outlet of the filter trough 1111, and the crushed mineral-containing filter blocks fall downwards from the discharge outlet of the filter trough 1111 into the feed trough 1241. In this embodiment, the power input end of the primary crushing body 1242 is connected to the drying cylinder 122 so that the primary crushing body 1242 rotates when the drying cylinder 122 rotates, thereby realizing the primary crushing of the mineral-containing filter blocks; preferably, the power input end of the primary crushing body 1242 and the drying cylinder 122 can be connected through a linkage component.The conveyor 1243 is disposed in the feed trough 1241 and located directly below the primary crushing body 1242. The conveyor 1243 is also connected to the drying cylinder 122 and rotates synchronously with the drying cylinder 122 to convey the ore-containing filter blocks that have been initially crushed by the primary crushing body 1242 from the feed inlet of the drying cylinder 122. Of course, the conveyor 1243 can also be rotatably disposed in the feed trough 1241 in other ways to convey the ore-containing filter blocks in other ways. To further improve the drying effect of the ore-containing filter blocks being conveyed into the drying cylinder 122, preferably, the feed inlet of the drying cylinder 122 is provided with a dividing wheel 1244, which can be fixed at the feed inlet of the drying cylinder 122 to divide the feed inlet of the drying cylinder 122 into multiple feed compartments, so that the ore-containing filter blocks can enter the interior of the drying cylinder 122 from the feed compartments. When the ore-containing filter blocks are large, they can be further crushed by compression.

[0125] See Figure 11 As shown, in this embodiment, the drum drive mechanism 125 further includes a motor tensioning plate 1255. A motor support 1254 is mounted on the drying bracket 121. The power motor 1251 is mounted on the motor support 1254 via the motor tensioning plate 1255. By adjusting the mounting position of the motor tensioning plate 1255 on the motor support 1254, the distance between the power wheel 1252 and the drying drum 122 can be adjusted, thereby tightening or loosening the transmission belt 1253. The motor support 1254 has multiple threaded holes along its height direction. The motor support 1254 and the motor tensioning plate 1255 are connected by tensioning screws. The mounting position of the motor tensioning plate 1255 can be adjusted by moving the tensioning screws.

[0126] See Figure 10 As shown, the primary crushing body 1242 includes a primary crushing shaft 12421 and a lever 12422 disposed on the primary crushing shaft 12421. Specifically, a primary transmission component 1245 is connected to the drying cylinder 122, and a secondary transmission component 1246 is connected to the primary transmission component 1245 and the primary crushing shaft 12421 respectively. The rotation of the drying cylinder 122 drives the primary transmission component 1245 to rotate, and the primary transmission component 1245 drives the secondary transmission component 1246 to rotate. The primary crushing shaft 12421 rotates under the action of the secondary transmission component 1246, thereby driving the lever 12422 to rotate around the axis of the primary crushing shaft 12421 above the feed trough 1241, thereby performing primary crushing of the mineral-containing filter blocks. In this embodiment, the drying cylinder 122 is provided with a primary crushing bearing seat 12423 for rotatably supporting the primary crushing shaft 12421, that is, the primary crushing shaft 12421 is rotatably disposed in the primary crushing bearing seat 12423, and a bearing may also be provided between the two. There are multiple levers 12422, which are distributed in a radiating pattern along the circumference of the initial crushing axis 12421.

[0127] See Figure 10As shown, in this embodiment, the conveying component 1243 is a spiral conveyor, including a feed conveying shaft 12431 and spiral conveying blades 12432 disposed on the feed conveying shaft 12431. Specifically, the feed conveying shaft 12431 can be coaxially arranged with the dividing wheel 1244, and the left end of the feed conveying shaft 12431 can be fixedly connected to the dividing wheel 1244 so as to rotate synchronously with the feed dividing wheel 1244 and the drying cylinder 122, thereby realizing the input of materials through the spiral conveying blades 12432. In this embodiment, the feed conveying shaft 12431, the dividing wheel 1244, and the drying cylinder 122 can be an integral structure.

[0128] See Figure 10 As shown, in this embodiment, the primary transmission component 1245 is a large gear, and the secondary transmission component 1246 is a small gear, with the large gear meshing with the small gear. Specifically, the primary transmission component 1245, i.e., the large gear, is sleeved on the outer wall of the drying cylinder 122, and the secondary transmission component 1246, i.e., the small gear, is installed at the power input end of the primary crushing shaft 12421. The rotation of the drying cylinder 122 drives the large gear to rotate, and the meshing of the large gear and the small gear realizes the rotation of the primary crushing shaft 12421. The outer diameter of the large gear is larger than that of the small gear.

[0129] Optionally, the primary transmission component 1245 and the secondary transmission component 1246 can also be belt drives, sprocket drives, etc.

[0130] See Figure 10 As shown, in this embodiment, the baffle mechanism 126 includes a baffle cover 1261, a baffle drive 1262, and a baffle plate 1263. The baffle cover 1261 is disposed outside the drying cylinder 122 and located at the discharge port of the drying cylinder 122. The baffle drive 1262 is disposed on the baffle cover 1261. The baffle drive 1262 is drivenly connected to the baffle plate 1263 so that the baffle plate 1263 can reciprocate within the baffle cover 1261 and the drying cylinder 122. In this embodiment, the baffle 1261 is used to collect the dried mineral-containing filter blocks to prevent them from dispersing and leaking. A discharge port is formed at the bottom of the baffle 1261, which is located above the feed port of the crushing shell 131. The discharge port of the drying cylinder 122 is provided with a baffle plate 1263 to control whether the dried filter blocks are discharged. When the baffle plate 1263 is inside the baffle 1261, that is, outside the discharge port of the drying cylinder 122, the dried filter blocks can be discharged from the discharge port to the outside of the drying cylinder 122 to fall into the crushing assembly 13. When the baffle plate 1263 moves from the discharge port to the inside of the drying cylinder 122, it prevents the dried filter blocks from being discharged. The baffle drive 1262 can be a cylinder or an electric telescopic rod, etc.

[0131] See Figure 15 to Figure 19As shown, in this embodiment, the pressing assembly 14 includes a pressing support 141, a clamping drive mechanism 142, a pressing drive mechanism 143, a residual powder scraping mechanism 146, and a residual material removal component 147. The clamping drive mechanism 142 is mounted on the pressing support 141, and a sample ring fixture 144 is mounted on the power output end of the clamping drive mechanism 142. The sample ring fixture 144 is used to secure the sample ring 17, which can hold mineral powder. Under the driving action of the clamping drive mechanism 142, the sample ring fixture 144 and the sample ring 17 move up and down, so that the sample ring 17 can move to the feeding position to receive the mineral powder falling from the crushing assembly 13. The sample ring fixture 144 is equipped with a sample ring detection switch 148 for detecting the sample ring 17. The pressing drive mechanism 143 is mounted on the clamping support 141. Above the drive mechanism 142, the power output end of the pressing drive mechanism 143 is equipped with a pressure head 145, which moves towards the sample ring 17 under the driving action of the pressing drive mechanism 143 to press the mineral powder inside the sample ring 17 to obtain a sample cake. The excess powder scraping mechanism 146 is set on the pressing support 141 to scrape off excess mineral powder on the sample ring 17 so that the sample ring 17 contains mineral powder with the same size as the inner diameter of the sample ring 17 and the same height as the sample ring 17. The excess material removal component 147 is set on the pressing support, and the excess material removal component 147 has multiple air holes. The excess material removal component 147 blows onto the sample cake through the multiple air holes to disperse excess mineral powder, ensuring the cleanliness of the sample cake and the surface of the sample ring 17, and reducing dust accumulation on the sample ring 17 during various stages of handling. Specifically, the pressing support 141 provides support for the clamping drive mechanism 142, the pressing drive mechanism 143, the drying assembly 12, and the crushing assembly 13. The clamping drive mechanism 142 and the pressing drive mechanism 143 are arranged vertically along the same vertical line. They can be arranged opposite each other so that the sample ring fixture 144 can move upwards, i.e., towards the pressing head 145, thereby driving the sample ring 17 upwards to the feeding position. This allows the mineral powder falling from the crushing assembly 13 to fall into the sample ring 17. The pressing head 145 can move downwards, i.e., closer to the sample ring fixture 144, to press the mineral powder within the sample ring 17. To control the pressing density of the sample cake, preferably, the pressing support 141 is provided with an excess powder scraping mechanism 146 to scrape away excess cake powder from the sample ring 17, ensuring that the sample ring 17 contains mineral powder equal to its inner diameter and height. This controls the volume of mineral powder before each pressing, thereby controlling the obtained sample cake. The thickness of the sample cake can be controlled by controlling the pressing drive mechanism 143. In this embodiment, the excess mineral powder is removed by blowing the pressed sample cake through the residual material removal component 147, thereby ensuring 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 the sample ring 17 is detected to be in 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 feeding position to receive the mineral powder falling from the crushing component 13.

[0132] See Figure 15 to Figure 19 As shown, the pressing support 141 includes a top plate 1411, two side plates 1412, a back plate 1413, a bottom plate 1414, a support 1415, and a front sealing plate 1416. The bottom plate 1414, side plates 1412, back plate 1413, and top plate 1411 are assembled sequentially from bottom to top in space. The back plate 1413 is arranged vertically, and the two side plates 1412 are respectively set on the two vertical sides of the back plate 1413. The top plate 1411 and the bottom plate 1414 are arranged horizontally at the top and bottom of the back plate 1413 and the two side plates 1412, respectively. 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 form a top working area for feeding and pressing. The support 1415 is located on the side of the back panel 1413 facing away from the two side panels 1412 (e.g.) Figure 16 (As shown on the right side), the drying assembly 12 can be supported. The drying assembly 12 is fixedly mounted on the support 1415 by two side support plates 1212. The clamping drive mechanism 142 can be fixed on the top plate 1411, and the pressing drive mechanism 143 can be fixed on the bottom plate 1414.

[0133] See Figure 19As shown, a central ring positioning plate 1417 may be provided on the pressing support 141, and a sample ring positioning hole 1418 is provided on the central ring positioning plate 1417 for positioning the sample ring 17 so that the sample ring 17 moves to the sample ring positioning hole 1418 under the action of the clamping drive mechanism 142 to receive the mineral powder flowing out of the crushing component 13. Specifically, a middle ring positioning plate 1417 is provided at the middle height position of the pressing support 141, that is, at the position between the clamping drive mechanism 142 and the pressing drive mechanism 143. The middle ring positioning plate 1417 can be installed at the bottom of the top working area and can be fixed to the side plate by bolts. It can receive the mineral powder flowing out of the crushing component 13. Furthermore, the middle ring positioning plate 1417 is provided with a sample ring positioning hole 1418 directly above the clamping drive mechanism 142. The sample ring positioning hole 1418 can be a round hole, so that the sample ring 17 moves upward to the sample ring positioning hole 1418 under the driving action of the clamping drive mechanism 142, that is, it is in the feeding position. The feeding position can be positioned through the sample ring positioning hole 1418 to ensure that the sample ring 17 is positioned in the feeding position, thereby ensuring the stability of receiving mineral powder and ensuring that mineral powder can be received. The central ring positioning plate 1417 is also provided with a residual powder hole, which is connected to the residual powder channel 149, so that excess cake powder on the sample ring 17 can be scraped into the residual powder hole and the residual powder channel 149 by the residual powder scraping mechanism 146. In this embodiment, the pressure head 145, the sample ring positioning hole 1418 of the central ring positioning plate 1417 and the sample ring fixture 144 are arranged coaxially, and the axis is arranged vertically.

[0134] See Figure 17 and Figure 19 As shown, the residual powder scraping mechanism 146 includes a scraping pusher 1461 and a scraper 1462; the scraper 1462 is disposed 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 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 (e.g., Figure 18 The right end shown is provided with a push plate 1463, which is located on one side of the back plate 1413 (e.g., Figure 18 On the right side), the push plate 1463 has guide shafts 1464 on both sides, and linear bearings are mounted on the back plate 1413. At the front ends of the two guide shafts 1464 on the other side of the back plate 1413 (e.g., on the right side), the push plate 1463 has guide shafts 1464 on both sides. Figure 19 The left end shown is equipped with a scraper 1462; the guide shaft 1464, scraper 1462, and push plate 1463 move along the axial direction of the scraper cylinder as it extends and retracts.

[0135] See Figure 19 and Figure 20As shown, in this embodiment, the residual material removal component 147 is a scraper for residual material. The scraper for residual material includes a long groove plate 1471 and a perforated plate 1472. The long groove plate 1471 is provided with a ventilation groove, and the perforated plate 1472 is covered above the groove. The perforated plate 1472 is provided with multiple air holes, and the air holes are connected to the ventilation groove.

[0136] See Figure 18 and Figure 21 As shown, in this embodiment, the pressing drive mechanism 143 includes a housing 1431, a pressing screw 1432, a pressing slider 1433, a pressing rod 1434, and a pressing power assembly. The housing 1431 is disposed on the top of the pressing support 141. The pressing screw 1432 and the pressing slider 1433 are threadedly connected and disposed inside the housing 1431. One end of the pressing rod 1434 is located inside the housing 1431 and connected to the pressing slider 1433. The other end of the pressing rod 1434 extends into the pressing support 141 and is connected to the pressing head 145. The pressing power assembly is used to drive the pressing screw 1432 to rotate. The power output end of the clamping power assembly is connected to the clamping screw 1432, which drives the clamping screw 1432 to rotate, causing the clamping slider 1433 to move up and down along the clamping screw 1432. This causes the clamping slider 1433 to drive the pressure rod 1434 and the pressure head 145 to move up and down, thereby pressing the mineral powder in the sample ring 17.

[0137] See Figure 18 and Figure 21 As shown, in this embodiment, the clamping power assembly includes a clamping motor 1435, a clamping wheel 1436, an input wheel 1437, and a timing belt 1438. The clamping motor 1435 is disposed on one side of the housing 1431. The output shaft of the clamping motor 1435 is connected to the input wheel 1437. The input wheel 1437 and the clamping wheel 1436 are connected via the timing belt 1438. The clamping wheel 1436 is connected to the clamping screw 1432. Specifically, a motor connecting plate 1439 is provided on one side of the housing 1431. The clamping motor 1435 is mounted on the motor connecting plate 1439 via a connecting plate seat 14310. A guide sleeve 14311 for the clamping rod 1434 to pass through is installed at one end of the housing 1431 near the top plate 1411. A bearing seat 14312 for supporting the rotation of the clamping screw 1432 is installed at the other end of the housing 1431 away from the top plate 1411. The rotation of the clamping motor 1435 drives the input wheel 1437 to rotate. The input wheel 1437 drives the clamping wheel 1436 to rotate via the synchronous belt 1438. The clamping wheel 1436 drives the clamping screw 1432 to rotate. The clamping screw 1432 drives the clamping slider 1433 to move up and down, which causes the dynamic pressure rod 1434 and the pressure head 145 to move up and down, thereby pressing the mineral powder in the sample ring 17.

[0138] See Figure 21As shown, in this embodiment, a guide block 14313 is provided along the axial direction of the outer shell 1431. The guide block 14313 extends into the interior of the outer shell 1431 and is slidably connected to the pressing slider 1433. The guide block 14313 can guide the pressing slider 1433 and prevent the pressing slider 1433 from rotating, thereby making the movement of the pressing slider 1433 more stable.

[0139] See Figure 22 and Figure 23 As shown, in this embodiment, the clamping drive mechanism 142 includes a clamping upper seat 1421, a clamping lower seat 1422, a lifting rod assembly, a connecting rod self-locking mechanism, and a clamping drive member 1423. The clamping upper seat 1421 is disposed on the pressing support seat 141 and located below the pressing head 145. The clamping lower seat 1422 is disposed on the pressing support seat 141 and located below the clamping upper seat 1421. The lifting rod assembly passes through the clamping upper seat 1421 and can move in the vertical direction. The connecting rod self-locking mechanism is disposed on the clamping upper seat 1421 and the clamping lower seat 1422. Between; one end of the lifting rod assembly is located above the clamping upper seat 1421 and connected to the sample ring fixture 144, and the other end of the lifting rod assembly is located below the clamping upper seat 1421 and hinged to one end of the connecting rod self-locking mechanism; the clamping drive 1423 has a telescopic end, and the telescopic end of the clamping drive 1423 is hinged to the other end of the connecting rod self-locking mechanism. The clamping drive 1423 drives the connecting rod self-locking mechanism through the telescopic end to drive the lifting rod assembly to rise and fall. When the sample ring 17 reaches the loading position, the connecting rod self-locking mechanism is in a self-locking state, and the lifting rod assembly stops rising and falling. The clamping drive 1423 drives the linkage self-locking mechanism, which in turn controls the lifting rod assembly to raise the sample ring fixture 144 and the sample ring 17. When the sample ring 17 reaches the loading position, the linkage self-locking mechanism enters a self-locking state, preventing the sample ring 17 from moving downwards. Furthermore, the linkage self-locking mechanism can lock when the pressure head 145 clamps, thus preventing loosening or displacement under pressure and improving the safety and reliability of the device. Optionally, the clamping drive 1423 can be a cylinder, an electric telescopic rod, etc.

[0140] See Figure 22 and Figure 23As shown, in this embodiment, the linkage self-locking mechanism includes a first linkage 1424, a second linkage 1425, a third linkage 1426, and a fourth linkage 1427. The first linkage 1424 is a T-shaped rod. The first connecting end of the first linkage 1424 is hinged to the telescopic end of the clamping drive member 1423. The second connecting end of the first linkage 1424 is hinged to the clamping lower seat 1422. The third connecting end of the first linkage 1424 is hinged to one end of the second linkage 1425. The second linkage 1426... The other end of 425, one end of the third link 1426, and one end of the fourth link 1427 are hinged together. The other end of the third link 1426 is hinged to the clamping lower seat 1422, and the other end of the fourth link 1427 is hinged to the lifting rod assembly. When the sample ring reaches the loading position, the third link 1426, the fourth link 1427, and the lifting rod assembly are located on the first straight line, and the second link 1425 and the horizontal bar of the T-shaped rod are located on the second straight line. The first straight line is perpendicular to the second straight line. Specifically, the first end of the first connecting rod 1424 is located on the vertical bar of the T-shaped rod, and the second and third ends are located on the horizontal bar of the T-shaped rod. The telescopic end of the clamping drive 1423 is hinged to the first end by a pin. The main body of the clamping drive 1423 is rotatably mounted on the clamping lower seat 1422. The second end of the first connecting rod 1424 is hinged to the clamping lower seat 1422 by a pin. The third end of the first connecting rod 1424 is hinged to one end of the second connecting rod 1425 by a pin. The other end of the second connecting rod 1425, one end of the third connecting rod 1426, and one end of the fourth connecting rod 1427 are hinged together by pins. The other end of the third connecting rod 1426 is hinged to the clamping lower seat 1422, and the other end of the fourth connecting rod 1427 is hinged to the lifting rod assembly by a pin. When the clamping drive 1423 is in the retracted position, i.e., when the sample ring reaches the loading position, the third link 1426, the fourth link 1427, and the lifting rod assembly are aligned on the first straight line, forming a self-locking mechanism in the vertical direction. The second link 1425 and the horizontal bar of the T-shaped rod are aligned on the second straight line, forming a self-locking mechanism in the horizontal direction. Because self-locking is formed in both the horizontal and vertical directions, when the pressure head 145 clamps, the position of the sample ring fixture 144 remains unchanged, improving the stability of the mechanism. When the telescopic end of the clamping drive 1423 retracts, the first link 1424 drives the second link 1425 to rotate. The second link 1425 then drives the third link 1426 and the fourth link 1427 to rotate. The fourth link 1427 drives the lifting rod assembly to move downwards, causing the sample ring fixture 144 to move away from the pressure head 145.

[0141] In addition to the rotation of the first link 1424 and the second link 1425, and the second link 1425 driving the third link 1426 and the fourth link 1427, the link self-locking mechanism can also be equipped with more links to achieve power transmission, which is not limited here.

[0142] See Figure 22 and Figure 23As shown, in this embodiment, the lifting rod assembly includes a lifting rod 1428, a positive and negative lead screw 1429, and a nut 14210. The lifting rod 1428 has an internal thread. One end of the positive and negative lead screw 1429 is threaded to the lifting rod 1428, and the other end of the positive and negative lead screw 1429 is connected to the nut 14210. The nut 14210 is connected to the sample ring fixture 144. The height position of the sample ring fixture 144 can be adjusted by turning the positive and negative lead screw 1429.

[0143] See Figure 22 and Figure 23 As shown, in this embodiment, a guide sleeve 14211 is provided on the top of the clamping upper seat 1421, and the lifting rod 1428 passes through the guide sleeve 14211, allowing the lifting rod 1428 to slide within the guide sleeve 14211. The guide sleeve 14211 has a guiding function.

[0144] The working principle of the pressing assembly is as follows: When the sample ring 17 is placed in the sample ring fixture 144, the clamping drive mechanism 142, i.e., the clamping drive component 1423, drives the self-locking mechanism of the connecting rod to clamp the sample ring fixture 144, raising the sample ring 17 and clamping it in the sample ring positioning hole 1418 of the middle ring positioning plate 1417, with the upper end face of the sample ring 17 flush with the upper plane of the middle ring positioning plate 1417; the crushed mineral powder flows into the sample ring 17. After installation, the scraping cylinder is activated, and the scraper 1462 scrapes the excess powder above the sample ring 17 into the excess powder channel 149. At this time, the sample ring 17 contains mineral powder with the same inner diameter and height as the sample ring 17. After the mineral powder reaches the same height as the sample ring 17, the pressing drive mechanism 143, i.e., the pressing power component, drives the pressure rod 1434 to compact the mineral powder through the pressure head 145. Then, the pressing drive mechanism 143 drives the pressure head 145 to retract to its original position. After that, the lower ring clamping cylinder retracts, and at the same time, the scraping cylinder retracts, and the scraper 1462 returns to its initial position. The residual material removal component 147 blows dust off the pressed sample cake. After the blowing is completed, the sample ring 17 is removed, and the inside of the ring contains a dense sample cake.

[0145] See also Figure 1 , Figure 24 to Figure 26The conveying device 2 includes: a linear motion component 21, a rotating component 22, a lifting component 23, and a clamp 24. The rotating component 22 is mounted on the linear motion component 21 and is used to perform reciprocating linear motion with the linear motion component 21 to achieve linear conveying of the sample cake in the X direction. The lifting component 23 is mounted on the rotating component 22, and the power output end of the lifting component 23 is provided with a clamp 24 for clamping the sample cake. The lifting component 23 adjusts the vertical height position with the lifting component 23 and, under the action of the rotating component 22, adjusts the horizontal angle synchronously with the lifting component 23 to grasp the sample ring 17 in different orientations or lower the sample ring 17 in different orientations. Under the action of the linear motion component 21, the lifting component 23 and the rotating component 22 perform horizontal linear motion synchronously to achieve adjustment of the height position, rotation angle, and linear conveying in the X direction of the sample cake, so as to convey the sample cake to the pre-detection position.

[0146] Specifically, such as Figure 1 As shown, the linear motion component 21 can be arranged along the X direction, and its power output end can perform reciprocating linear motion along the X direction; the rotating component 22 can be set on the power output end of the linear motion component 21, and can perform reciprocating linear motion in the X direction along with the power output end of the linear motion component 21; the lifting component 23 can be set on the rotating component 22, and can rotate horizontally under the action of the rotating component 22 to adjust the orientation of the clamp 24 set on the power output end of the lifting component 23, that is, adjust the angle, so that the clamp 24 can be set towards the sample ring 17 to clamp the sample ring 17, and under the action of the linear motion component 21, the whole is transported in the X direction to transport the sample ring 17 containing the sample cake from the side of the sample preparation device 1 to the side of the element detection device 3 along the X direction, and the height position is adjusted by the lifting component 23 to place the sample ring 17 containing the sample cake in the pre-detection position, thereby realizing the transport of the sample ring 17 containing the sample cake. The clamp 24 can be a pneumatic gripper with an arc-shaped claw structure at its power output end. The pneumatic finger can be suspended below the rotating component 22. The front end of the pneumatic finger is equipped with opposing arc-shaped claws. When the pneumatic gripper is opened or closed, the arc-shaped claw structure opens or closes, realizing the gripping or release of the sample ring 17. That is, when the pneumatic finger is opened or closed, the arc-shaped claws open or close. Of course, the clamp 24 can also be other locking structures, and no limitation is made on it in this embodiment. The handling device 2 may also include a hub 25, a cable tray support 26, and a follower cable tray 27.

[0147] See also Figure 1 , Figure 24 to Figure 26The linear motion component 21 includes: a guide rail 211, a slide plate 212, a linear drive mechanism 213, and a linear transmission mechanism 214. The guide rail 211 is arranged along the X direction and serves as a guide. The slide plate 212 is slidably mounted on the guide rail 211 along its length and supports the rotating component 22 and the lifting component 23, thereby driving the rotating component 22 and the lifting component 23 to perform reciprocating linear motion synchronously. The linear drive mechanism 213 is mounted on the slide plate 212, and a linear transmission mechanism 214 is provided between the power output end of the linear drive mechanism 213 and the guide rail 211 to convert the rotation of the linear drive mechanism 213 into linear motion of the slide plate 212 along the length direction of the guide rail 211, thereby realizing the linear transport of the sample cake on the slide plate 212 along the X direction.

[0148] Specifically, the bottom wall of the slide plate 212 is provided with two first sliders 215, and the base frame 4 is provided with a large support plate 41. The large support plate 41 serves as the supporting foundation for the sample preparation device 1. The sample preparation device 1 can be installed in two parts, upper and lower. A small support plate 42 can be provided above the large support plate 41, with the upper part installed on the small support plate 42 and the lower part installed on the large support plate 41. The two ends of the small support plate 42 are indirectly fixed to the large support plate 41 through support plate brackets, so that the small support plate 42 and the large support plate 41 form a fixed frame at a certain height. At the same time, multiple sample preparation devices 1 can be placed as needed. The large support plate 41 is provided with two guide rails 211, and the two first sliders 215 are respectively adapted to the two guide rails 211 and slidably connected to them, for guiding the sliding of the slide plate 212 along the length direction of the guide rails 211. Of course, the number of first sliders 215 and guide rails 211 can also be other numbers, and no limitation is made in this embodiment. The linear drive mechanism 213 can be a motor, specifically an X-axis motor, which can be fixed to the top wall of the slide plate 212 via an X-axis motor mount. The output shaft of the linear drive mechanism 213 is rotatably mounted through the slide plate 212. The linear transmission mechanism 214 is located below the slide plate 212 and is connected to the linear drive mechanism 213, the guide rail 211, or the large support plate 41, respectively, to convert the rotation of the linear drive mechanism 213 into linear motion of the slide plate 212 along the length of the guide rail 211.

[0149] See also Figure 1 , Figure 24 to Figure 26The linear transmission mechanism 214 includes a rack 2141 and an X-axis gear 2142. The rack 2141 is disposed on the guide rail 211 or the large support plate 41 along the length direction of the guide rail 211. The X-axis gear 2142 is rotatably disposed on the slide plate 212 and meshes with the rack 2141. The power input end of the X-axis gear 2142 is connected to the power output end of the linear drive mechanism 213, and is used to rotate and perform linear motion along the length direction of the rack 2141 under the drive of the linear drive mechanism 213, so as to drive the slide plate 212 to reciprocate in the X direction.

As shown, the lifting assembly 23 includes: a support base 231, a guide member 232, a lifting rod seat 233, and a drive cylinder 234; the support base 231 provides support; the guide member 232 is disposed above the support base 231; the lifting rod seat 233 passes through the support base 231, and one end of the lifting rod seat 233 (e.g., ...) is...

Furthermore, a guide key 237 can be provided at the top of the shaft-shaped structure, and a keyway is provided inside the protective sleeve 235, which is adapted to the guide key 237 to guide the movement of the lifting rod seat 233, so that the lifting rod seat 233 can only perform lifting movements. The drive cylinder 234 can be located above the support base 231 and on one side of the guide member 232 (e.g., Figure 28 (As shown on the right), the drive cylinder 234 can be an electric cylinder. The electric cylinder extends a push-pull rod that is pinned to the lug 236 of the lifting rod seat 233. By controlling the extension and retraction of the electric cylinder rod, the height of the lifting rod seat 233 is adjusted, thereby adjusting the height of the clamp 24 mounted on the lifting rod seat 233. Of course, in other embodiments, the lifting assembly 23 may also be supported only by the support base 231 and the drive cylinder 234 may drive the clamp 24 to adjust its height.

The detection component 32 is disposed on the power output end of the horizontal plane moving component 31 and is used to move horizontally under the action of the horizontal plane moving component 31 to move the sample cake to its location for element detection. Specifically, the horizontal plane moving component 31 can be disposed on a carrier plate 33, which serves as a support and is placed on a base frame 4 as a mounting platform for the device.

Of course, other detection sensors can also be used to detect elemental grade. In this embodiment, the detection method is not limited.

[0156] In this embodiment, the carrier plate 33 may also be provided with a swing assembly 35. The swing assembly 35 is rotatably disposed on the carrier plate 33 to support the sample cake and drive the sample cake to swing, so that the sample cake swings from the pre-detection position to the detection position, so that the detection assembly 32 can be moved to the detection position for sample cake detection by the horizontal plane moving assembly 31. The swing assembly 35 may be provided with a collar 351 for supporting the collar 351, so that the sample ring 17 carrying the sample cake can be rotated to the detection position for detection.

[0157] See also Figure 1 The carrier plate 33 may also be equipped with a standard sample chamber 36 for holding standard sample cakes. The detection component 32 is further used to move to the standard sample chamber under the action of the horizontal plane moving component 31 to detect the elemental samples of the standard sample cakes, obtain standard test data, and then compare the standard test data with the standard stored data to calibrate the detection component 32. Specifically, the standard sample cakes can be tested periodically by the detection component 32 to verify the accuracy of the detection data based on the test results, thereby calibrating the detection component 32 and ensuring the accuracy of the detection.

[0158] See also Figure 1The horizontal plane moving component 31 includes an X-axis module 311 and a Y-axis module 312. The Y-axis module 312 is mounted on the X-axis slider of the X-axis module 311 and moves along the X-axis with the X-axis slider to drive the detection component 32 to move along the X-axis and drive the detection component 32 to move along the Y-axis, thereby realizing the horizontal plane movement of the detection component 32. Specifically, the X-axis module 311 is connected to the carrier plate 33 through the frame spacing, and the slider of the X-axis module 311 can move along the X-axis. The Y-axis module 312 is mounted on the slider of the X-axis module 311, and the slider of the Y-axis module 312 can move relative to the slider of the X-axis module 311 along the Y-axis. The moving plate 34 is mounted on the slider of the Y-axis module 312, and indirectly drives the detection component 32 on the moving plate 34 to perform planar movement by controlling the movement of the sliders in both directions of the X-axis module 311 and the Y-axis module 312.

[0159] In this embodiment, the detection component 32 includes a detection light source and a detection sensor, which can perform elemental detection using X-ray fluorescence technology.

[0160] See Figure 29 This is a schematic diagram of the swing assembly provided in this embodiment of the present invention. As shown in the figure, the swing assembly 35 includes: a swing plate 352 and a swing drive mechanism 353; the swing plate 352 is rotatably mounted on the carrier plate 33, and a collar 351 is provided at the end of the swing plate 352 for supporting the sample ring; the power output end of the swing drive mechanism 353 is connected to the swing plate 352 for driving the swing plate 352 to swing. Specifically, the swing drive mechanism 353 may include a swing motor and a belt, so as to drive the rotating shaft provided on the swing plate 352 to swing, that is, drive the swing plate 352 to swing. The swing plate 352 can be a double-hole swing plate, with collars 351 at both ends, so that the two collars 351 are respectively located at the pre-detection position and the detection position, so that the swing motor can drive the swing plate 352 to rotate, so that the two collars 351 can switch between the two positions simultaneously, thereby improving the detection switching efficiency. The collars 351 are detachably mounted on the swing plate 352 for replacement. The sample ring 17, which can be transported by the transport device 2, arrives above the collar 351 located at the pre-detection position. The sample ring 17 is placed into the collar 351, completing the entry of the sample into the element detection device 3 for detection. After the transport device 2 exits the housing, the electromagnetic automatic double door 5 closes, and the swing plate 352 rotates to rotate the sample ring 17 to the detection position for detection by the detection light source and detection sensor.

[0161] See Figure 30 to Figure 31The figure illustrates a preferred structure of the electromagnetic automatic double door provided by an embodiment of the present invention. As shown, the electromagnetic automatic double door 5 includes: a door frame assembly 51, two double door bodies 52, a door drive assembly 53, a reset member 54, and a synchronous transmission member 55; the two double door bodies 52 are disposed inside the door frame assembly 51 in a manner capable of moving towards or away from each other; the door drive assembly 53 is disposed on the door frame assembly 51 and is used to apply an opening driving force to one of the double door bodies 52, causing one double door body 52 to move away from the other double door body 52, thereby opening the double door bodies 52; the reset member... A 54 is disposed between the door frame assembly 51 and one of the double door bodies 52, and is used to apply a reset force to one of the double door bodies 52 so that one of the double door bodies 52 can be reset in a free state, thereby realizing the closing of the double door body 52; a synchronous transmission member 55 is connected to both double door bodies 52 respectively, and is used to realize the synchronous movement between the two double door bodies 52, so as to realize the synchronous opposite movement or synchronous opposite movement between the two double door bodies 52, thereby realizing the opening or closing of the double door bodies 52. Specifically, the door frame assembly 51 may be provided with a guide structure 56 for guiding the reciprocating linear movement of the two double door bodies 52.

[0162] In this embodiment, the door frame assembly 51 may include an upper door frame 511, a lower door frame 512, a left door frame 513, a right door frame 514, and a side suspension plate 515 connected to each other. A door drive assembly 53 may be mounted on the side suspension plate 515, and the door drive assembly 53 may be connected to one of the double door bodies 52 (e.g., a hinged door body 52) via a pin. Figure 30The left door (shown) is pinned to the right door frame 514. A guide rod 562 with a second slider 561 can be clamped between the left door frame 513 and the right door frame 514. There are two pairs of guide rods 562 on each side, one above the other. The second sliders 561 on each side are connected to the two double door bodies 52, enabling the two double door bodies 52 to reciprocate on the guide rods 562, thus guiding the movement of the two double door bodies 52. The door drive assembly 53 can be an electromagnet structure, which can pull the double door bodies closer to the door drive assembly 53 when the electromagnet is energized. The reset member 54 can be a tension spring structure, located between the left door and the lower door frame. It is stretched after the left door is opened, applying a tensile force to the left door so that when the electromagnet structure is de-energized, the left door can reset to the closed position under the action of the tension spring. The synchronous transmission member 55 includes a first door pulley 551, a second door pulley 552, and a door pull strap 553 disposed on the first door pulley 551 and the second door pulley 552. The door frame assembly 51, for example, the upper door frame 511, is equipped with tensioning wheel plates 516 and fixed wheel plates 517 on both sides. The first door pull wheel 551 and the second door pull wheel 552 are respectively pinned to the tensioning wheel plate 516 and the fixed wheel plate 517. The two wheels are connected by a door pull strap 553 so that the two wheels rotate synchronously. The left door is pressed against the upper door pull strap 553 by a door pressure plate, and the right door is pressed against the lower door pull strap 553 by a door pressure plate. When the electromagnet is energized, pulling the left door to the left will cause the first door pull wheel 551 to rotate counterclockwise. At the same time, the lower door pull strap moves to the right, causing the right door to move to the right. At this time, the double doors open. When the electromagnet is de-energized, since there is a tension spring between the left door and the lower door frame, the tension spring tightens the left door to move to the right, indirectly causing the right door to move to the left. At this time, the double doors close.

[0163] The working principle of this slurry grade detection system is as follows: When a certain process point in the plant needs to perform slurry grade detection, the slurry can be controlled to flow into the sample preparation equipment 1 for sample preparation. After the sample preparation is completed, the transport equipment 2 reaches the position of the sample ring 17, and the arc-shaped claw is raised above the height of the sample ring 17 by the lifting component 23. The claw is then rotated above the sample ring 17 by the rotating component 22. After the arc-shaped claw is lowered into place by the lifting component 23, the sample ring 17 is picked up. After the claw is picked up, the transport equipment 2 rotates the arc-shaped claw toward the element detection equipment 3, the X-axis motor starts, and the sample ring 17 is placed on the collar 351 of the swing plate 352. Then, the transport equipment 2 withdraws, and the element detection equipment 3 starts the detection cycle.

[0164] In summary, the slurry grade detection system provided in this embodiment uses sample preparation equipment 1 to prepare the incoming slurry, transforming the slurry into a sample cake. The sample cake is then transported to the pre-detection position on the side of the elemental detection equipment via transport equipment 2, and elemental detection is performed on the sample cake by elemental detection equipment 3. Specifically, the crushing component 13 in the sample preparation equipment 1 crushes the dried filter blocks to obtain mineral powder, and the pressing component 14 presses the mineral powder into a sample cake for detection. The crushing component 13 transports the dried filter blocks to the crushing disc 132 for crushing via a feeding mechanism 134, eliminating the need for gravity. This ensures the transport capacity for low-density mineral powder, preventing it from falling into the crushing disc 132 under gravity and causing material blockage in the feed channel. This not only ensures the normal operation of the equipment but also improves detection efficiency.
