Description

Technical Field

[0001] The invention relates to an online sodium cyanide concentration monitoring device with good anti-clogging effect for a leaching section, belonging to the technical field of sodium cyanide concentration monitoring. Background Art

[0002] Sodium cyanide is a highly toxic substance. Concentration monitoring of its solution refers to the accurate determination of the effective cyanide content in the sodium cyanide solution through specific methods and techniques to ensure its safety during production, use, storage or processing, while meeting relevant regulations and process requirements. In the leaching section of the cyanide workshop, concentration monitoring of the sodium cyanide solution is a key link in the production process.

[0003] Traditional sodium cyanide concentration monitoring methods mainly rely on manual sampling and laboratory analysis. This method is not only time-consuming and labor-intensive, but also cannot achieve real-time monitoring, making it difficult to meet the real-time and accuracy requirements of modern chemical production. Sodium cyanide solution may contain various impurities during the production process, such as ore particles, mud, etc. These impurities can easily clog the pipes and probes of the monitoring device, resulting in inaccurate monitoring data or even inability to monitor normally. Once the monitoring probe is blocked, not only does it require frequent shutdowns for cleaning, it may also cause production accidents, resulting in economic losses and safety hazards. Summary of the Invention

[0004] The object of the present invention is to provide an online monitoring device for sodium cyanide concentration with good anti-clogging effect for a leaching section, so as to solve the problems raised in the above background technology.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: Compared with the prior art, the present invention provides an online sodium cyanide concentration monitoring device with good anti-clogging effect for a leaching section, comprising a control display, an electrical control box, a sodium cyanide concentration monitor, a monitoring probe and a detection pipeline, wherein support feet are provided at the lower corners of the detection pipeline, a disassembly plate is provided on the front side of the detection pipeline, a diversion pipeline 1 is provided on the upper left side of the detection pipeline, a centrifugal filter assembly is provided in the diversion pipeline 1, a diversion pipeline 2 is provided on the lower side of the diversion pipeline 1, one end of the diversion pipeline 2 is connected to the top left side of the detection pipeline, a diversion assembly is provided in the diversion pipeline 2 and the detection pipeline, a filter plate filter assembly is provided in the detection pipeline, the electrical control box and the sodium cyanide concentration monitor are both provided on the upper side of the detection pipeline, and the monitoring probe is provided on one side of the sodium cyanide concentration monitor and on the right side of the filter plate filter assembly.

[0006] Through the above technical solution, the sodium cyanide solution to be monitored is transported through the detection pipeline, and the support feet play a stabilizing supporting role on the lower corner of the detection pipeline to ensure that the pipeline will not shake due to factors such as the flow of the solution during operation. The solution to be monitored first enters through the diversion pipeline 1, and the centrifugal filter component therein will perform preliminary centrifugal filtration on the solution to remove some larger particle impurities. The filtered solution then enters the left top of the detection pipeline through the diversion pipeline 2. The diversion pipeline 2 and the diversion component in the detection pipeline guide the solution to flow along a specific path, thereby improving the smoothness of the solution flow. The solution entering the detection pipeline is further filtered through the filter plate filter component to remove fine impurities. Finally, the monitoring probe located on the right side of the filter plate filter component monitors the concentration of the purified solution under the action of the sodium cyanide concentration monitor. The monitoring data and other information can be displayed on the control display after processing by the electrical control box. The disassembly and assembly plate facilitates the inspection and cleaning of the inside of the detection pipeline.

[0007] The setting of the support feet enhances the stability of the detection pipeline and ensures the reliability of the overall operation of the device. The dual filtering effect of the centrifugal filter assembly and the filter plate filter assembly can effectively remove impurities in the solution, avoid impurities clogging the monitoring probe and pipeline, and improve the accuracy of monitoring and the service life of the device. The guide assembly guides the solution to flow smoothly, reducing the retention and sedimentation of the solution in the pipeline. The design of the disassembly and assembly plate facilitates the later maintenance of the interior of the pipeline, reducing the difficulty and cost of maintenance. The monitoring probe is located on the right side of the filter plate filter assembly to ensure that it is in contact with a fully filtered solution, further improving the accuracy of concentration monitoring.

[0008] Preferably, a protection box is provided on the outside of the detection pipe, the front side of the protection box is flipped and connected with a box door, and the control display is provided on the front side of the protection box.

[0009] Through the above technical solution, the protective box wraps the core components such as the detection pipeline, forming a relatively closed space, reducing the direct impact of external environmental factors on internal components. The box door can be flipped open to facilitate staff to operate and maintain the detection pipeline and other components inside the protective box. The control display is set on the front side of the protective box, which is convenient for staff to observe the monitored sodium cyanide concentration and other data information at any time.

[0010] The protective box can effectively prevent external dust, water vapor, collisions, etc. from damaging core components such as the detection pipeline, thereby extending the service life of the device. The flip design of the box door makes the inspection and maintenance of internal components more convenient. The front setting of the control display allows staff to obtain monitoring data in a timely manner without opening the protective box, which improves work efficiency and reduces the interference with the internal environment caused by frequent opening of the protective box.

[0011] Preferably, a liquid inlet connecting pipe is provided on the upper side of the protection box, one end of which is connected to one side of the diversion pipe, and a liquid discharge connecting pipe is provided on the right side of the protection box, one end of which is connected to the right side of the detection pipe.

[0012] Using this technical solution, the sodium cyanide solution to be monitored is delivered through the inlet connection pipe on the upper side of the protection box to diversion pipe 1, where it enters the device's detection process. After detection and filtration, the solution is discharged from the right side of the detection pipe through the drain connection pipe, completing the entire monitoring cycle.

[0013] The setting of the liquid inlet connecting pipe and the liquid discharge connecting pipe makes the input and output of the solution more convenient and orderly, avoiding waste and pollution caused by leakage of the solution. The reasonable connection between the connecting pipe and the protection box and related pipelines ensures the sealing of the solution transportation and improves the environmental protection and safety of the device.

[0014] Preferably, the centrifugal filter assembly includes a guide cylinder, which is arranged at the inner top of the guide pipe 1, a filter cylinder is arranged on the lower side of the guide cylinder, and a cross connecting seat is arranged on the lower side of the filter cylinder.

[0015] Through the above technical solution, when the solution enters the diversion pipe, it first passes through the diversion tube, which guides the solution into the filter cartridge. The filter cartridge rotates to generate centrifugal force. The larger particle impurities in the solution are thrown to the inner wall of the filter cartridge under the action of centrifugal force, and are thus filtered and retained. The filtered solution flows out from the pores of the filter cartridge.

[0016] The guide tube can make the solution enter the filter cartridge more orderly, improve the efficiency of centrifugal filtration, and the filter cartridge can effectively remove larger particle impurities in the solution through centrifugal action, reduce the burden on subsequent filter components, and reduce the probability of clogging of the entire device.

[0017] Preferably, the diversion assembly includes a motor, which is arranged on the lower side of the detection pipe, and a connecting rod 1 is provided at the shaft end of the motor, and a cross plug is provided at the top of the connecting rod 1, and the cross plug is inserted in the cross connecting seat, and an impeller 1 is provided on the outside of the connecting rod 1, and the impeller 1 is placed in the diversion pipe 2, and a bevel gear 1 is provided on the outside of the connecting rod 1, and one side of the bevel gear 1 is meshed and connected with the bevel gear 2, and a connecting rod 2 is provided on one side of the bevel gear 2, and an impeller 2 is provided at the end of the connecting rod 2, and the impeller 2 is placed in the detection pipe, and a bracket is provided on the outside of the connecting rod 2, and one side of the bracket is connected to the inner bottom of the detection pipe.

[0018] Through the above technical solution, after the motor is started, it drives the connecting rod to rotate. The cross plug at the top of the connecting rod is inserted into the cross connecting seat, which drives the filter cartridge to rotate together, thereby enhancing the centrifugal filtration effect.

[0019] At the same time, impeller 1 on the outside of connecting rod 1 rotates within diversion pipe 2, pushing the solution therein and providing a diversion mechanism. The rotation of connecting rod 1 also drives bevel gear 1. Because bevel gear 1 meshes with bevel gear 2, bevel gear 2 drives connecting rod 2, which in turn rotates impeller 2 at the end of connecting rod 2 within the detection pipe, pushing the solution therein to flow.

[0020] The bracket supports the second connecting rod to ensure its rotation stability. The motor provides power through a series of transmission structures, which not only enhances the filtering effect of the centrifugal filter assembly, but also can guide the solution in the diversion pipe 2 and the detection pipe through impeller 1 and impeller 2 respectively, thereby accelerating the flow rate of the solution, reducing the retention of the solution in the pipe, and further reducing the risk of blockage.

[0021] The bracket ensures the stability of the rotation of the second connecting rod and the reliability of the diversion effect. The entire diversion assembly improves the smoothness of the solution flow in the device and improves the monitoring efficiency.

[0022] Preferably, the filter plate filter assembly includes a mounting plate, which is detachably connected to the upper side of the detection pipe, a protrusion is provided on the outer side of the mounting plate, a plurality of sockets are provided on the lower side of the mounting plate, a plug strip is plugged into the socket, and a filter plate is provided on the lower side of the plug strip.

[0023] Through the above technical solution, the mounting plate is fixed to the upper side of the detection pipe through a detachable connection, and the protrusions on the outside thereof make it convenient for workers to install and remove the mounting plate.

[0024] The socket on the lower side of the mounting plate cooperates with the socket strip on the filter plate to fix the filter plate in the detection pipe. When the solution flows through the filter plate, the filter plate will filter out the fine impurities in the solution and further purify the solution. The detachable mounting plate and the matching structure of the socket and the connector strip make the replacement and cleaning of the filter plate very convenient, reducing the maintenance cost and difficulty. The filter plate can effectively remove fine impurities in the solution, ensure the cleanliness of the solution entering the monitoring probe, improve the accuracy of concentration monitoring, and avoid small impurities clogging the monitoring probe.

[0025] Preferably, the number of the filter plates is three, and filter plates with three pore sizes, namely, coarse, medium and fine, are arranged in sequence from left to right.

[0026] Through the above technical solution, when the solution flows through the three filter plates from left to right, it first passes through the coarse-pore filter plate to filter out larger residual impurities in the solution; then passes through the medium-pore filter plate to remove medium-sized impurities; and finally passes through the fine-pore filter plate to filter out fine impurities. Through this gradually refined filtration process, the impurities in the solution are fully removed.

[0027] Three filter plates with different pore sizes perform coarse, medium and fine filtration in turn, realizing graded filtration of the solution, greatly improving the filtration effect and more thoroughly removing various impurities in the solution. This graded filtration method can also prevent a single filter plate from quickly clogging due to excessive burden, thereby extending the service life of the filter plate and further ensuring the anti-clogging performance of the device and the accuracy of monitoring.

[0028] Compared with the prior art, the present invention has the following beneficial effects: The dual filtration design of the centrifugal filter assembly and the filter plate filter assembly can effectively remove large and small particles of impurities in the liquid, prevent impurities from clogging the monitoring probe, and ensure long-term stable operation of the monitoring device.

[0029] The guide assembly of the present invention drives the first and second impellers to rotate through a motor, thereby optimizing the flow path of the liquid in the guide pipe 2 and the detection pipe, ensuring uniform distribution of the liquid, providing a stable detection environment for the sodium cyanide concentration monitor, and improving monitoring accuracy. After the liquid in the detection pipe undergoes multi-stage filtration, it can effectively reduce the interference of impurities on the monitoring probe, further improving the accuracy of the monitoring data.

[0036] The detection pipe 4 is installed inside the protection box 1, and support legs 5 are welded at the outer corners. The bottoms of the support legs 5 are in contact with the inner bottom of the protection box 1, which plays a role in stably supporting the detection pipe 4.

[0037] The front side of the detection pipe 4 is connected to a disassembly plate 6 by bolts, and a sealing gasket is provided at the connection between the disassembly plate 6 and the detection pipe 4. When the inside of the detection pipe 4 needs to be cleaned or maintained, the disassembly plate 6 can be removed by removing the bolts, which is convenient to operate.

[0038] A liquid inlet connection pipe 15 extends through the upper side of the protective box 1. One end of this connection pipe 15 is connected to the left-center portion of the diversion pipe 7. The other end is connected to the test liquid delivery pipe of the leaching section of the cyanidation plant 1. Diversion pipe 7 is arranged at an angle above and to the left of the test pipe 4, and houses a centrifugal filter assembly 8.

[0039] The guide tube 81 in the centrifugal filter assembly 8 is welded to the inner top of the guide pipe 7. The guide tube 81 is funnel-shaped and can guide the liquid to be tested to flow smoothly into the filter tube 82 below.

[0040] The filter cartridge 82 is a cylindrical structure with its sidewalls covered with filter holes. A cross connector 83 is welded to the lower side of the filter cartridge 82 , and a slot matching the cross insert 103 is provided at the center of the cross connector 83 .

[0041] The lower side of the diversion pipe 1 7 is connected to the diversion pipe 2 9, and one end of the diversion pipe 2 9 is welded to the top left side of the detection pipe 4, so that the liquid preliminarily filtered by the centrifugal filter assembly 8 can enter the detection pipe 4 through the diversion pipe 2 9.

[0042] A diversion assembly 10 is installed in both the diversion pipe 2 9 and the detection pipe 4, wherein the motor 101 is fixed to the lower side of the detection pipe 4 by bolts, and the output shaft end of the motor 101 passes through the bottom of the detection pipe 4 and is connected to the bottom end of the connecting rod 102. A cross plug 103 is welded to the top of the connecting rod 102, and the cross plug 103 is inserted into the cross connecting seat 83. When the motor 101 is started, it can drive the connecting rod 102, the cross plug 103 and the filter cartridge 82 to rotate together to achieve centrifugal filtration.

[0043] An impeller 104 is welded to the outer side of the portion of the connecting rod 102 located in the guide pipe 2 9 . When the impeller 104 rotates along with the connecting rod 102 , it can push the liquid in the guide pipe 2 9 to flow toward the detection pipe 4 .

[0044] A bevel gear 105 is welded to the outer middle part of the connecting rod 102, and the bevel gear 105 is meshed with the bevel gear 2 106. The bevel gear 2 106 is welded to one end of the connecting rod 2 107. The connecting rod 2 107 is installed in the detection pipe 4 through the bracket 109. The bracket 109 is fixedly connected to the inner wall of the detection pipe 4. The other end of the connecting rod 2 107 is welded with the impeller 2 108. When the connecting rod 102 rotates, the connecting rod 2 107 and the impeller 2 108 are driven to rotate through the bevel gear transmission, thereby promoting the flow of liquid in the detection pipe 4.

[0045] A filter plate filter assembly 11 is installed in the detection pipe 4, and the mounting plate 111 is detachably connected to the upper side of the detection pipe 4 by bolts. A protrusion 112 is integrally formed on the outer side of the mounting plate 111. The protrusion 112 contacts the top of the detection pipe 4 to play a limiting role.

[0046] A plurality of sockets 113 are welded to the lower side of the mounting plate 111 . Sockets 113 are plugged with plug strips 114 . The lower side of the plug strips 114 is fixedly connected to the filter plate 115 .

[0047] There are three filter plates 115 , which have three pore sizes, coarse, medium and fine, from left to right. They can filter the liquid in a step-by-step manner. When the filter plate 115 needs to be replaced, it is only necessary to remove the mounting plate 111 and pull out the connector strip 114 .

[0048] The electric control box 12 and the sodium cyanide concentration monitor 13 are both fixed to the upper side of the detection pipe 4 by a bracket. A control circuit is provided inside the electric control box 12, which is electrically connected to the control display 3, the motor 101 and the sodium cyanide concentration monitor 13 to realize control of the entire device.

[0049] The monitoring probe 14 is installed on one side of the sodium cyanide concentration monitor 13, and the probe portion extends into the detection pipe 4 and is located on the right side of the filter plate filter assembly 11, for detecting the sodium cyanide concentration of the fully filtered liquid.

During actual operation, the liquid to be tested enters the guide pipe 1 7 through the liquid inlet connecting pipe 15, and is guided to the filter cartridge 82 through the guide cylinder 81. The motor 101 drives the filter cartridge 82 to rotate, and uses centrifugal force to perform preliminary filtration on the liquid. The filtered impurities remain in the filter cartridge 82. The liquid after preliminary filtration flows into the guide pipe 2 9 and enters the detection pipe 4 under the action of the impeller 104. The liquid entering the detection pipe 4 flows to the filter plate filter assembly 11 under the action of the impeller 2 108.

[0051] After being filtered through the three-stage filter plate, the sodium cyanide concentration is detected by the monitoring probe 14, and the detection data is transmitted to the sodium cyanide concentration monitor 13 and displayed on the control display 3. Finally, the detected liquid is discharged through the drainage connection pipe 16. The synergistic effect of the multiple filtering components and the diversion components effectively prevents the monitoring probe 14 and the pipeline from being blocked, thereby ensuring the accuracy and stability of the online monitoring of the sodium cyanide concentration.

[0052] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
