Description

Technical Field

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

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

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

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

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

[0006] Furthermore, the filter assembly, the cake drying assembly and the mineral powder pressing assembly are arranged in sequence from top to bottom according to the spatial height position. Preferably, the filter assembly is arranged at the uppermost end and fixed on the first fixed machine base, and the liquid inlet of the filter assembly is located at the top to input the slurry and make the slurry flow downward to filter through the filter assembly, filter out the liquid in the slurry, and realize that the slurry initially presents a high moisture content and a layered cake state, so that the solid minerals in the slurry form a mineral-containing filter block, and obtain a mineral-containing filter block.

[0007] Preferably, the mineral powder pressing assembly is arranged at the lowest end and can be fixed on the second fixed machine base, the filter assembly and the mineral powder pressing assembly have a height difference, the cake drying assembly and the cake block crushing assembly are arranged between the filter assembly and the mineral powder pressing assembly, and the cake drying assembly and the cake block crushing assembly can be fixed on the mineral powder pressing assembly. The feeding end of the cake drying assembly extends into the interior of the filter assembly to receive the mineral-containing filter block obtained by the filter assembly, and the mineral-containing filter block is dried by the cake drying assembly to reduce the water content, so that the mineral-containing filter block forms a dried filter block.

[0008] Furthermore, the cake crushing assembly is arranged below the cake drying assembly, and the feeding port of the cake crushing assembly is connected with the discharging port of the cake drying assembly, so that the dried filter block is crushed by the cake crushing assembly to obtain mineral powder, and the cake is crushed uniformly. The mineral powder pressing assembly is arranged below the cake crushing assembly.

[0009] Furthermore, a sample ring is provided on the mineral powder pressing assembly so that the mineral powder discharged from the discharge port of the cake crushing assembly falls into the sample ring, and the mineral powder in the sample ring is pressed by the mineral powder pressing assembly. The crushing shell is located between the cake drying assembly and the mineral powder pressing assembly, and is fixed to the top of the mineral powder pressing assembly by bolts. The crushing disk and the feeding mechanism are arranged inside the crushing shell, and the feeding mechanism is located on one side of the crushing disk, and the other side of the crushing disk is connected to the power output end of the crushing drive mechanism. The crushing drive mechanism can drive the crushing disk to rotate, thereby crushing the dried filter block to obtain mineral powder.

[0010] Compared with the prior art, the online slurry multi-element grade analysis system provided by the present invention prepares the inflowing slurry through the sample preparation equipment to convert the slurry in the slurry state into a solid cake to obtain a solid cake; the solid cake is transported to the pre-detection position on the side of the element detection device of the transport column through the transport equipment, and the solid cake is detected by the element detection device. Non-contact detection can be adopted, and there is no need to perform direct contact detection through the detection window. At the same time, the solid cake elements will not pollute the detection window, avoiding the pollution and wear of the detection window, and solving the problem of low detection accuracy of the existing grade meter detection of the element detection in direct contact with the slurry. At the same time, since the direct target sample for detection is a solid cake, and the preparation of the solid cake is not affected by the concentration, it indirectly ensures that the system has high accuracy and stable solid cake, which is not affected by the slurry concentration, and improves the accuracy of the detection results. Therefore, the system can detect multiple element grades at the same time, with high detection accuracy and not affected by the slurry concentration, and the key components are not polluted or worn, with a long life and convenient maintenance.

In this embodiment, the element detection device 3 can perform non-contact element detection on the solid cake by using X-ray fluorescence. Figure 1 As shown, in this embodiment, there are two sample preparation devices 1. Of course, there may be one or three sample preparation devices 1. The number of sample preparation devices 1 is not limited in this embodiment. In this embodiment, an electromagnetic automatic double-opening door 5 may be provided between the element detection device 3 and the sample preparation device 1, which is used to open when the transport device 2 transports the solid cake, so that the transport device 2 transports the solid cake from the electromagnetic automatic double-opening door 5 to the detection station, and closes and seals the element detection device 3 to prevent the radiation of the element detection device 3.

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

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

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

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

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

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

[0062] Specifically, the filter base 111 plays a supporting role to support the filter container 112, the filter flap 113, the knock-off mechanism 114 and the locking mechanism 115. The top plate of the filter base 111 is provided with a flap clearance hole, the filter container 112 is arranged above the filter base 111, and the open end of the filter container 112 can extend from the flap clearance hole to the inside of the filter base 111. The top of the filter container 112 is a feed port, which is connected to a liquid inlet pipe 1121 to inject slurry into the filter container 112. The filter container 112 can also be connected to an air compressor to pressurize the inside of the filter container 112, that is, the air pressure of the air compressor is pumped into the filter container 112, and the water in the filter container 112 is discharged into the liquid collecting tank 18 by positive pressure, and discharged to the slurry pool through the drain pipe 19. The filter flap 113 is movably disposed on the filter base 111. Preferably, the filter flap 113 is rotatably disposed at the open end of the filter container 112 so as to be rotated to the position as shown in FIG. Figure 5 In the blocked state shown, the filter flap 113 blocks the open end of the filter container 112, and filter holes are provided on the filter flap 113, so that the liquid in the slurry can flow out from the filter holes and prevent the solid minerals in the slurry from flowing out, so that the liquid in the slurry flows out from the holes of the filter flap 113 to the outside of the filter container 112 under the action of positive pressure, and the solid minerals in the slurry remain on the filter flap 113 to form a mineral cake. There may be two picking mechanisms 114, which are respectively arranged on both sides of the filter flap 113. In the present embodiment, there may be two picking mechanisms 114, which are respectively arranged on both sides of the filter flap 113. The cake block air knife may be arranged tilted, and is arranged in parallel with the filter flap 113 in the open state, so that when the filter flap 113 is rotated to the open state, the mineral cake is blown off, that is, when the filter flap 113 is in the open state, the cake on the filter flap 113 is sprayed, that is, a spraying force is applied to the cake, so that the cake is blown off from the filter flap 113 and falls into the cake drying assembly 12. Of course, in other embodiments, the picking mechanism 114 may also be other picking mechanisms, such as a scraping mechanism, which is used to apply a scraping force to the cake so that the cake can fall.

[0063] In this embodiment, in order to prevent the filter flap 113 from rotating and opening during the filtering process, preferably, the filter base 111 is further provided with a locking mechanism 115, which is used to lock the filter flap 113 on the filter base 111 when the filter flap 113 is in a blocked state, so as to ensure the stability of the filter flap 113 in blocking and filtering. Specifically, there can be two locking mechanisms 115, which are respectively arranged on both sides of the filter flap 113 (relative to the filter flap 113). Figure 4The filter flap 113 is used to lock and release the filter flap 113, so that when the filter flap 113 is in a blocked state, the filter flap 113 is locked, and after filtering is completed, the filter flap 113 can be released so that the filter flap 113 can be rotated to an open state, so that the mineral cake falls along the top wall of the filter flap 113 under the action of blowing or scraping, and falls downward under the limiting action of the side plate of the filter base 111. The locking mechanism 115 can be a self-locking pneumatic clamp to clamp the filter flap 113 in a blocked state, thereby achieving pressure locking and release of the filter flap 113. Of course, the locking mechanism 115 can also be other locking structures, which are not limited in this embodiment.

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

[0065] Continue to see Figure 5, a filter drainage trough 119 is provided below the filter flap 113 for collecting liquid flowing down from the filter flap 113. Specifically, the filter drainage trough 119 is installed below the filter flap 113 and can swing with the swing of the filter flap 113. In this embodiment, the filter drainage trough 119 can be connected to an inclined drainage pipe, and its liquid outlet can be set in the liquid collecting tank 18, so that the water in the filter container 112 can be discharged into the liquid collecting tank 18 through the guidance of the filter drainage trough 119 and the drainage pipe by positive pressure, and then discharged to the pulp pool.

[0066] Continue to see Figure 5 and Figure 6 , a filter material trough 111 is further provided on the filter base 111 below the filter flap 113, so that the material cake falls into the filter material trough 111, and under the guidance of the filter material trough 111, falls into the material cake drying assembly 12.

The discharge port of the filter material trough 111 can be arranged downward, so that the mineral-containing material cake falls into the material cake drying assembly 12 under the action of gravity.

[0067] In this embodiment, the filter container 112 is further provided with a liquid level sensor 1122, which may be an electronic liquid level gauge, for detecting the slurry level in the filter container 112, so that when the slurry level in the filter container 112 reaches a preset level, the slurry input to the filter container 112 is stopped, thereby controlling the slurry input before filtering by the filter container 112.

[0068] Continue to see Figure 4 and Figure 6The liquid inlet pipe 1121 is connected to a slurry inlet connector 1124, which is provided with three communication channels, namely, a gas channel, a liquid level measurement channel and a liquid inlet channel, each of which is connected to the liquid inlet pipe 1121 and the filter container 112. The liquid level sensor 1122 is installed on the slurry inlet connector 1124, and the liquid level sensor 1122 is arranged in the liquid level measurement channel and the liquid inlet pipe 1121 to detect the slurry level in the filter container 112.

The liquid inlet channel of the slurry inlet connector 1124 is also connected with a slurry inlet seat 1125. The slurry inlet seat 1125 is provided with two outlets, one of which is connected to the liquid inlet channel of the slurry inlet connector 1124 through a slurry inlet valve 1126, which is used to control the connection between the slurry inlet seat 1125 and the liquid inlet channel of the slurry inlet connector 1124, and the other outlet may be connected to the liquid collecting tank 18, and a residual slurry valve 1127 is provided between the two to control the connection between the other outlet and the liquid collecting tank 18. In this embodiment, the slurry inlet valve 1126 and the residual slurry valve 1127 can be connected to the slurry inlet seat 1125 through a threaded joint, and then the slurry inlet valve 1126 is connected to the slurry inlet connector 1124. The hose is connected to the residual slurry valve 1127 through a joint and then inserted into the liquid collecting tank 18; the slurry inlet connector 1124 and the filter container 112 can be connected by a snap-fit ​​connection. Of course, the air passage can also be connected to the atmosphere by connecting a solenoid valve at the air inlet hole to control whether to allow the atmosphere to be introduced or whether the air pressure is increased.

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

As shown in the figure, the cake drying component 12 includes: a drying support 121, a drying cylinder 122, a drying mechanism 123 and a cake primary crushing mechanism 124; the drying cylinder 122 is rotatably arranged on the drying support 121, and the drying mechanism 123 is sleeved on the outer periphery of the drying cylinder 122, which is used to heat and dry the minerals in the drying cylinder 122 to obtain dried cake blocks. In order to improve the drying effect of the cake, preferably, a cake primary crushing mechanism 124 is provided at the feeding port of the drying cylinder 122, which is used to perform primary crushing on the cake before the cake enters the feeding port of the drying cylinder 122, and to feed the cake blocks obtained by the primary crushing into the drying cylinder 122 from the feeding port of the drying cylinder 122.
