DETAILED DESCRIPTION

[0037] Exemplary embodiments of the present disclosure will be described in detail with reference to the drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it is understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure can be more thoroughly understood, and the scope of the present disclosure can be accurately conveyed to those skilled in the art. It should be noted that the embodiments in the present disclosure and the features in the embodiments can be combined with each other without conflict. The present disclosure will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0038] Reference Figures 1-2The figure illustrates a preferred structure of the online slurry solid sample cake preparation device provided by an embodiment of the present invention. As shown, the device includes: a filtration assembly 1, a cake drying assembly 2, a cake crushing assembly 3, and a mineral powder pressing assembly 4; wherein,

[0039] The filter assembly 1 is used to filter the incoming slurry, so that the solid minerals in the slurry form a ore-containing cake; the cake drying assembly 2 is used to dry the ore-containing cake obtained by the filter assembly to obtain a dried cake block; the cake crushing assembly 3 is used to crush the dried cake block obtained by the cake drying assembly to obtain mineral powder; the mineral powder pressing assembly 4 is used to press the mineral powder obtained by the cake crushing assembly to form a solid cake.

[0040] Specifically, the filter assembly 1, the cake drying assembly 2, and the mineral powder pressing assembly 4 are arranged from top to bottom in terms of spatial height (relative to...). Figure 1 (As shown in the diagram) arranged sequentially. The filter assembly 1 is located at the top and can be fixed to the first fixed base 5. The inlet of the filter assembly 1 is located at the top to input the slurry, allowing it to flow downwards and pass through the filter assembly 1 for filtration. This removes the liquid from the slurry, resulting in a slurry with a high initial moisture content and a layered cake state. This allows the solid minerals in the slurry to form a mineral-containing cake. The mineral powder pressing assembly 4 is located at the bottom and can be fixed to the second fixed base 6. The filter assembly 1 and the mineral powder pressing assembly 4 have a height difference. The cake drying assembly 2 and the cake crushing assembly 3 are arranged between the filter assembly 1 and the mineral powder pressing assembly 4. Both the cake drying assembly 2 and the cake crushing assembly 3 can be fixed to the mineral powder pressing assembly 4. Furthermore, the inlet of the cake drying assembly 2 can extend into the interior of the filter assembly 1 to receive the mineral-containing cake obtained from the filter assembly 1. The cake drying assembly 2 then dries the mineral-containing cake to reduce its moisture content, forming a dried cake. The cake crushing component 3 is located on one side of the cake drying component 2 (e.g., Figure 2 As shown on the left), the feed end of the cake crushing component 3 is connected to the discharge end of the cake drying component 2, so that the dried cake is crushed by the cake crushing component 3 to obtain mineral powder and achieve a uniform state of cake crushing. The mineral powder pressing component 4 is set below the cake crushing component 3, and the mineral powder pressing component 4 may be equipped with a sample ring 7 so that the mineral powder discharged from the discharge end of the cake crushing component 3 falls into the sample ring 7 and is pressed by the mineral powder pressing component 4 to obtain a solid cake. Then, the elemental grade of the solid cake is detected. The elemental grade of the solid cake can be detected indirectly by non-contact detection using existing conventional detection sensors to obtain the elemental grade of the slurry. The first fixed base 5 and the second fixed base 6 play a supporting role. They can be an integrated structure or two independent fixed bases. In this embodiment, there is no limitation on them.

[0041] In this embodiment, a liquid collection tank 8 is also provided below the filter assembly 1 so that the liquid filtered out in the filter assembly 1 can be discharged into the liquid collection tank 8. A drain pipe 9 can also be connected to the liquid collection tank 8 for discharging the liquid or other materials in the liquid collection tank 8 into the slurry tank.

[0042] It can be seen that the slurry is filtered by the filtration component 1 to remove the liquid from the slurry, causing the solid minerals in the slurry to form a mineral-bearing cake. The cake is then dried by the cake drying component 2 to form a dried cake block. The dried cake block is then crushed by the cake crushing component 3 to obtain mineral powder. Finally, the mineral powder is pressed by the mineral powder pressing component 4 to obtain a solid cake. This process transforms the slurry from a slurry state into a uniform and dense solid cake, allowing for elemental grade detection on the solid cake. This provides a non-contact sample preparation method for the detection sensor, eliminating the need for direct contact detection through the detection window. Furthermore, the solid cake does not contaminate the detection window, avoiding contamination and wear. This solves the problem of existing slurry elemental grade meters where direct contact with the slurry through the detection window leads to easy contamination or wear, affecting detection accuracy and increasing maintenance workload. Additionally, the solid cake is unaffected by the slurry concentration, improving the accuracy of the detection results.

[0043] See Figures 3-6 The figure illustrates a preferred structure of the filter assembly provided in an embodiment of the present invention. As shown, the filter assembly 1 includes: a filter base 11, a filter container 12, an air compressor (not shown), a filter plate 13, a rejection mechanism 14, and a locking mechanism 15; wherein,

[0044] The filter base 11 provides support; the filter container 12 has an open bottom and is mounted on the filter base 11. The filter container 12 has an inlet pipe 121 for injecting slurry into it; an air compressor is connected to the filter container 12 to pressurize it, allowing the slurry inside to be filtered under positive pressure; a filter plate 13 is movably mounted on the filter base 11 and has a closed and open state. In the closed state, the filter plate 13 blocks the open end of the filter container 12, forming a closed, sealed chamber inside the filter container 12. This allows the liquid in the slurry to flow out through the holes in the filter plate 13 to the outside of the filter container 12 under positive pressure, while solid minerals in the slurry remain on the filter plate 13 to form a mineral cake; a rejection mechanism 14 is located on one side of the filter plate 13 (e.g., ...). Figure 6 (As shown on the right), it is used to apply force to the cake on the filter plate 13 when the filter plate 13 is in the open state, so that the cake is discarded from the filter plate 13 and falls into the cake drying assembly 2.

[0045] Specifically, the filter base 11 provides support for the filter container 12, filter plate 13, rejection mechanism 14, and locking mechanism 15. The top plate of the filter base 11 has a flap clearance hole. The filter container 12 is positioned above the filter base 11, and its open end extends from the flap clearance hole into the interior of the filter base 11. The top of the filter container 12 is a feed inlet connected to a liquid inlet pipe 121 to inject slurry into the filter container 12. The filter container 12 can also be connected to an air compressor to pressurize its interior. Air pressure is injected into the filter container 12, and water is discharged into the collection tank 8 via positive pressure and then discharged into the slurry pool via the drain pipe 9. The filter plate 13 is movably mounted on the filter base 11. Preferably, the filter plate 13 is rotatably mounted at the open end of the filter container 12, allowing it to rotate to... Figure 4 In the blocked state shown, the filter plate 13 blocks the opening end of the filter container 12. The filter plate 13 is provided with filter holes, allowing the liquid in the slurry to flow out from the filter holes and preventing the solid minerals in the slurry from flowing out. Under the action of positive pressure, the liquid in the slurry flows out from the holes of the filter plate 13 to the outside of the filter container 12, while the solid minerals in the slurry remain on the filter plate 13 to form a ore-containing cake. There can be two rejection mechanisms 14, which are respectively arranged on both sides of the filter plate 13. In this embodiment, the rejection mechanism 14 can be a cake air knife. The cake air knife can be inclined and arranged parallel to the filter plate 13 in the open state, so that when the filter plate 13 is rotated to the open state, the ore-containing cake is blown off. That is, when the filter plate 13 is in the open state, the cake is sprayed onto the filter plate 13, that is, a spraying force is applied to the cake so that the cake is blown off the filter plate 13 and falls into the cake drying assembly 2. Of course, in other embodiments, the rejection mechanism 14 can also be other rejection mechanisms, such as a scraping mechanism, for applying scraping force to the cake so that the cake can fall.

[0046] In this embodiment, to prevent the filter plate 13 from rotating and opening during filtration, preferably, the filter base 11 is also provided with a locking mechanism 15, which is used to lock the filter plate 13 onto the filter base 11 when the filter plate 13 is in a blocked state, so as to ensure the stability of the filter plate 13 in the blocked filtration process. Specifically, there can be two locking mechanisms 15, which are respectively arranged on both sides of the filter plate 13 (relative to the filter base 11). Figure 5The locking mechanism 15 is arranged at the position shown in the figure, and is used to lock and release the filter plate 13, so that the filter plate 13 is locked when the filter plate 13 is in the closed state, and the filter plate 13 can be released after the filtering is completed, so that the filter plate 13 can be rotated to the open state, so that the ore-containing material cake falls along the top wall of the filter plate 13 under the action of blowing or scraping, and falls downward under the limiting action of the side plate of the filter base 11. The locking mechanism 15 can be a self-locking pneumatic clamping jaw, so as to realize the clamping of the filter plate 13 in the closed state, and further realize the pressure locking and release of the filter plate 13. Of course, the locking mechanism 15 can also be other locking structures, which are not limited in the embodiment.

[0047] Referring to Figures 3-6 , the filter plate 13 can also be connected with a filter plate driving mechanism 16 for driving the filter plate 13 to rotate, so that the filter plate can switch states. Specifically, the filter plate pin seat 17 can be provided on the filter base 11, and the fixed seat of the filter plate driving mechanism 16 can also be installed on the filter base 11. The filter plate pin seat 17 and the fixed seat of the filter plate driving mechanism 16 can be fixed on the filter base 11 by bolts or other connecting members. The power output end of the filter plate driving mechanism 16 can extend to the inside of the filter base 11 through the top plate of the filter base 11, and the power output end of the filter plate driving mechanism 16 is provided with a connecting lug 18. The filter plate pin seat 17 is also provided with a connecting lug 18 located in the filter base 11, and the connecting lug on the filter plate pin seat 17 is located between the opening end of the filter container 12 and the connecting lug on the filter plate driving mechanism 16. The filter plate 13 is rotatably connected with the connecting lug on the filter plate pin seat 17 and the connecting lug on the filter plate driving mechanism 16 through a pin shaft, for driving the filter plate 13 to rotate around the connecting lug on the filter plate pin seat 17 under the driving action of the power output end of the filter plate driving mechanism 16, so as to realize state switching. The filter plate driving mechanism 16 can be a flap cylinder structure, and the power output end thereof is arranged downward, for pushing the left end of the filter plate 13 to move up and down, so that the filter plate 13 can rotate around the connecting lug on the filter plate pin seat 17. That is to say, when filtering is needed, the power output end of the flap cylinder structure, that is, the filter plate driving mechanism 16, is extended, and the filter plate 13 is closed in place, that is, rotated to the closed state. After the filtering is completed, the power output end of the flap cylinder structure, that is, the filter plate driving mechanism 16, is retracted, and the filter plate 13 is opened in place, that is, rotated to the open state.

[0048] Referring to Figure 4 , a filter liquid discharge groove 19 is arranged below the filter plate 13, for collecting the liquid flowing from the filter plate 13. Specifically, the filter liquid discharge groove 19 is installed below the filter plate 13 and can swing with the filter plate 13. In the embodiment, the filter liquid discharge groove 19 can be connected with an inclined liquid discharge pipe, and the liquid outlet of the liquid discharge pipe can be arranged in the liquid collecting groove 8, so that the water in the filter container 12 is guided to the liquid collecting groove 8 through the filter liquid discharge groove 19 and the liquid discharge pipe by positive pressure, and is discharged to the slurry pool.

[0049] With reference to the foregoing Figure 4 and Figure 5 , the filter base 11 is further provided with a filter material groove 111 below the filter plate 13, so that the filter cake falls into the filter material groove 111 and falls into the filter cake drying assembly 2 under the guidance of the filter material groove 111. Specifically, the filter material groove 111 is arranged in the filter base 11, and the ore-containing filter cake can fall along the top wall of the filter plate 13 under the action of spraying or scraping, and falls into the filter material groove 111 under the limiting action of the side plate of the filter base 11. The discharge port of the filter material groove 111 can be arranged downward, so that the ore-containing filter cake falls into the filter cake drying assembly 2 under the action of gravity.

[0050] In the embodiment, the filter container 12 is further provided with a liquid level sensor 122, which can be an electronic liquid level meter, for detecting the liquid level of the ore slurry in the filter container 12, so as to terminate the input of the ore slurry into the filter container 12 when the liquid level of the ore slurry in the filter container 12 reaches a preset liquid level, thereby controlling the ore slurry input before filtering of the filter container 12. The filter container 12 can also be provided with a pressure switch 123 for detecting the pressure in the filter container 12, and opening when the pressure in the filter container 12 reaches a preset pressure, i.e. greater than the preset pressure, so that the filter container 12 is connected with the external atmosphere, thereby controlling the filtering state in the filter container 12 to avoid insufficient or excessive filtering of the filter cake.

[0051] With reference to the foregoing Figure 3 and Figure 5The liquid inlet pipe 121 is connected with a slurry inlet connector 124, which is provided with three communication channels, i.e. a gas channel, a liquid level measuring channel and a liquid inlet channel, each of which is communicated with the liquid inlet pipe 121 and the filter container 12. A liquid level sensor 122 is installed on the slurry inlet connector 124, which is arranged in the liquid level measuring channel and the liquid inlet pipe 121 to detect the liquid level of the ore slurry in the filter container 12. A pressure switch 123 is arranged on the side wall of the slurry inlet connector 124, which is communicated with the gas channel to measure the pressure of the gas channel, the liquid inlet pipe 121 and the filter container 12 and control the on-off between the atmosphere and the gas channel. An air inlet hole 1241 is also arranged on the side wall of the slurry inlet connector 124, which is connected with the gas channel. The air inlet hole 1241 can be provided with an air inlet joint to connect with an air compressor to provide air pressure to the filter container 12. The slurry inlet channel of the slurry inlet connector 124 is also connected with a slurry inlet seat 125, which is provided with two outlets. One of the outlets is communicated with the slurry inlet channel of the slurry inlet connector 124 through a slurry inlet valve 126 to control the on-off between the slurry inlet seat 125 and the slurry inlet channel of the slurry inlet connector 124. The other outlet can be communicated with the liquid collecting tank 8, and a residual slurry valve 127 is arranged between the two to control the on-off between the other outlet and the liquid collecting tank 8. In this embodiment, the slurry inlet valve 126 and the residual slurry valve 127 can be connected with the slurry inlet seat 125 through threaded joints, the slurry inlet valve 126 is connected with the slurry inlet connector 124, and the residual slurry valve 127 is connected with the liquid collecting tank 8 through a hose. The slurry inlet connector 124 and the filter container 12 can be connected by buckling. Of course, the gas channel can also be connected with an electromagnetic valve at the air inlet hole to control whether the atmosphere or air pressure is introduced.

[0052] The working principle of the filter assembly is as follows: when work is needed, the flap cylinder, namely the filter plate driving mechanism 16, extends to enable the filter plate 13 to be closed in place, and then the self-locking pneumatic clamping jaw, namely the locking mechanism 15, extends to lock the filter plate 13; the excess slurry valve 127 is closed, the slurry inlet valve 126 is opened, the pressure switch 123 is opened to be connected to the atmosphere, or the electromagnetic valve at the air inlet hole is opened to be connected to the atmosphere; the ore slurry enters the filter container 12 through the slurry inlet seat 125, the slurry inlet valve 126 and the slurry inlet connector 124; when the liquid level detected by the liquid level sensor 122 reaches the preset liquid level, the slurry inlet valve 126 is closed, and the excess slurry valve 125 is opened, and the excess ore slurry flows out through the excess slurry valve 125 to the liquid collecting tank 8 and is discharged to the slurry pool; at the same time, the electromagnetic valve at the air inlet hole is actuated to be connected to the filter container 12 by the air pressure of the air compressor, and the water in the filter container 12 is discharged to the slurry pool through the filter liquid discharge groove 19; when the pressure in the filter container 12 reaches the preset pressure, the electromagnetic valve at the air inlet hole is actuated to be connected to the atmosphere, and the self-locking pneumatic clamping jaw and the flap cylinder are sequentially retracted, and the filter plate 13 is opened to be in place, and then the filter plate 13 is rotated to an open state, and the cake wind knives on both sides are opened to spray the cake, so that the entire cake is cut off and falls into the filter cake groove 111.

[0053] Referring to Figures 7-8 It shows the preferred structure of the cake drying assembly provided by the embodiment of the utility model. As shown in the figure, the cake drying assembly 2 comprises a drying support 21, a drying cylinder 22, a drying mechanism 23 and a cake primary crushing mechanism 24; wherein the drying cylinder 22 is rotatably arranged on the drying support 21, and the outer periphery of the drying cylinder 22 is sleeved with the drying mechanism 23, which is used for heating and drying the mineral in the drying cylinder 22 to obtain dried cake. In order to improve the drying effect of the cake, preferably, the cake primary crushing mechanism 24 is arranged at the feeding port of the drying cylinder 22, which is used for primary crushing the cake before entering the feeding port of the drying cylinder 22, and sending the primary crushed cake into the drying cylinder 22 from the feeding port of the drying cylinder 22.

[0075] In summary, the online ore pulp solid sample cake preparation device provided in the embodiment filters the ore pulp through the filtering assembly 1 to filter out the liquid in the ore pulp, so that the solid ore material in the ore pulp forms an ore-containing material cake, and an ore-containing material cake is obtained; the ore-containing material cake is dried by the cake drying assembly 2 to form a dried cake block; the dried cake block is broken by the cake block breaking assembly 3 to obtain ore powder; and the ore powder is pressed by the ore powder pressing assembly 4 to obtain a solid cake. The ore pulp is converted from a slurry state to a uniform and dense solid cake, which can be used for element grade detection, providing a non-contact sample preparation requirement for the detection sensor. There is no need for direct contact detection through the detection window, and the solid cake does not pollute the detection window, avoiding pollution and wear of the detection window. The problem of easy pollution or wear of the detection window affecting the detection accuracy and increasing the maintenance workload of the existing ore pulp element grade instrument is solved. At the same time, the solid cake is not affected by the concentration of the ore pulp, improving the accuracy of the detection result.

The rejection mechanism 141 is disposed on the filter base 11 and located on one side of the filter plate 13, and is used to reject the mineral-containing filter blocks on the filter plate 13 so that they fall into the cake drying assembly 2. The locking mechanism 15 includes a locking mechanism 151 and a locking dust cover 152 for covering the locking mechanism 151.

[0079] In this embodiment, to ensure that the ore-containing filter blocks can fall from the filter plate 13 into the cake drying assembly 2, two rejection mechanisms 141 are provided, respectively arranged on both sides of the filter plate 13. Of course, there can be one or more rejection mechanisms 141, which is not limited here. In this embodiment, the rejection mechanism 141 can be a cake block air knife, which can be inclined and arranged parallel to the filter plate 13 in the open state, so as to blow off the ore-containing filter blocks when the filter plate 13 is rotated to the open state. That is, when the filter plate 13 is in the open state, it sprays air onto the ore-containing filter blocks on the filter plate 13, that is, it applies a blowing force to the ore-containing filter blocks so that the ore-containing filter blocks are blown off the filter plate 13 and fall into the cake drying assembly 2. Of course, in other embodiments, the rejection mechanism 141 can also be other rejection mechanisms, such as a scraping mechanism, used to apply a scraping force to the cake so that the cake can fall. When air-knife blows through the mineral-containing filter blocks, dust may overflow from the gaps in the structural components. A dust cover 142 for the discarding mechanism is installed to prevent this overflow. The dust cover 142 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 142 can have pneumatic or electric transition joints required for the mechanism's operation, facilitating structural maintenance.

[0080] In this embodiment, the filter base 11 is further provided with a locking mechanism 15. The locking mechanism 15 includes a locking mechanism 151 and a locking dust cover 152. The locking mechanism 151 is used to lock the filter plate 13 onto the filter base 11 when the filter plate 13 is in the closed state, so as to ensure the stability of the filter plate 13 in sealing and filtering. Specifically, the locking mechanism 15 includes a locking mechanism 151, and there can be two locking mechanisms 151, which are respectively arranged on both sides of the filter plate 13 (relative to the filter base 11). Figure 17The locking mechanism 151 can be a self-locking pneumatic clamping jaw to achieve clamping of the filter plate 13 in the closed state, thereby achieving pressure locking and release of the filter plate 13. Of course, the filter plate 13 can also be other locking structures, which are not limited in the embodiment. The locking dust cover 152 covers the exposed part of the locking mechanism 151 to prevent dust in the filter assembly 1 from overflowing. Optionally, the locking dust cover 152 includes a dustproof shell and a dustproof brush arranged in the dustproof shell.

[0081] Referring to Figure 16 As shown, the filter plate 13 can also be connected with a filter plate driving mechanism 16 for driving the filter plate 13 to rotate to enable the filter plate to switch states.

The filter plate 13 is rotatably connected with the connecting lug on the filter plate pin seat 17 and the connecting lug on the filter plate driving mechanism 16 through a pin shaft, for driving the filter plate 13 to rotate around the connecting lug on the filter plate pin seat 17 under the driving action of the power output end of the filter plate driving mechanism 16 to achieve state switching. The filter plate driving mechanism 16 can be a flap cylinder structure, and the power output end thereof is arranged downward for pushing the left end of the filter plate 13 to move up and down to enable the filter plate 13 to rotate around the connecting lug on the filter plate pin seat 17. That is, when filtering is needed, the power output end of the flap cylinder structure, i.e., the filter plate driving mechanism 16, is extended, and the filter plate 13 is closed in place, i.e., rotated to the closed state. After filtering is completed, the power output end of the flap cylinder structure, i.e., the filter plate driving mechanism 16, is retracted, and the filter plate 13 is opened in place, i.e., rotated to the open state.
