Description

Technical Field

[0001] This invention relates to the field of harmless treatment technology for gold mine cyanide tailings, specifically to an environmentally friendly harmless treatment device for gold mine cyanide tailings. Background Technology

[0002] Cyanide tailings from gold mines are solid wastes remaining after gold, silver, and other valuable metals are extracted using the cyanide gold extraction process. They are also one of the main solid wastes in the gold smelting industry. Their core characteristics are the presence of residual cyanide and various heavy metals, classifying them as toxic and hazardous solid waste. The harmless treatment device for cyanide tailings from gold mines is used to treat the tailings containing residual cyanide and heavy metals generated during the gold cyanide gold extraction process, ensuring that they meet harmless treatment standards.

[0003] In existing technologies, many gold mine cyanide tailings do not collect reaction process data in a timely manner during harmless treatment, which may lead to waste of reagents and over-treatment. The harmless treatment reaction of cyanide tailings is a dynamic process, and key parameters such as cyanide ion concentration, pH value, and dissolved oxygen will continuously change with the reaction time. Summary of the Invention

[0004] The purpose of this invention is to provide an environmentally friendly harmless treatment device for gold mine cyanide tailings, in order to solve the problem mentioned in the background art that many gold mine cyanide tailings do not collect reaction process data in a timely manner during harmless treatment, which may lead to waste of reagents and over-treatment. The harmless treatment reaction of cyanide tailings is a dynamic process, and key parameters such as cyanide ion concentration, pH value, and dissolved oxygen will continuously change with the reaction time.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an environmentally friendly gold mine cyanide tailings harmless treatment device, comprising:

[0006] The reaction chamber is used for the harmless treatment of gold mine cyanide tailings.

[0007] A drug dispensing mechanism is located at the top of the reaction chamber. The drug dispensing mechanism includes a drug pump. A mounting frame is fixedly installed on the top of the drug pump. The drug pump is fixedly installed inside the mounting frame. A limit frame is fixedly installed at the bottom of the drug pump. A sealing element is fixedly installed below the limit frame. An observation window is fixedly installed on the outside of the reaction chamber. A discharge pipe is fixedly installed on one side of the reaction chamber. A check valve is installed inside the discharge pipe.

[0008] A data acquisition mechanism is located at the top of the reaction chamber. The data acquisition mechanism includes a PLC controller. The PLC controller is fixedly installed on the top of the reaction chamber. A cyanide ion concentration display terminal is fixedly installed on the outside of the reaction chamber. A cyanide ion concentration sensor is fixedly installed inside the reaction chamber. A pH value display terminal is fixedly installed on the outside of the reaction chamber. A pH value sensor is fixedly installed inside the reaction chamber. A heavy metal concentration display terminal is fixedly installed on the outside of the reaction chamber. A heavy metal concentration sensor is fixedly installed inside the reaction chamber. The PLC controller is connected to the drug delivery pump.

[0009] A mixing mechanism is located inside the reaction chamber. The mixing mechanism includes a drive motor, which is fixedly installed on the outside of the reaction chamber.

[0010] Preferably, the output end of the drug delivery pump is fixedly connected to the reaction chamber via a first connecting pipe, and the input end of the drug delivery pump is fixedly connected to the reagent tower via a second connecting pipe. The reaction chamber is used for the harmless treatment of gold mine cyanide tailings. A cyanide ion concentration sensor, a pH sensor, and a heavy metal concentration sensor capture core parameters such as cyanide ion concentration, pH value, dissolved oxygen, and heavy metal concentration in real time. The data can be directly fed back to the PLC controller and displayed on the cyanide ion concentration display, pH value display, and heavy metal concentration display, respectively. Preferably, a reagent tower is fixedly installed on the top of the reaction chamber, and a second sealing cover is provided on the top of the reagent tower. The reagent tower is used to store the reagent for removing gold mine cyanide tailings, and the second sealing cover increases the sealing performance of the reagent tower.

[0011] Preferably, the PLC controller is connected to the cyanide ion concentration sensor, and the cyanide ion concentration display terminal is also connected to the cyanide ion concentration sensor. The PLC controller can compare the collected data with a preset threshold and then control the dosing pump to discharge the material. The dosing pump draws the reagent from inside the reagent tower into the reaction chamber through the first connecting pipe and the second connecting pipe.

[0012] Preferably, the PLC controller signal is connected to the pH sensor, and the pH display terminal signal is also connected to the pH sensor. The design of the first sealing element and the second sealing cover increases the airtightness of the device. The observation window facilitates user observation of the internal conditions of the reaction chamber. The discharge pipe and check valve facilitate material discharge. The drive motor drives the rotating rod to rotate the stirring roller, which can quickly and thoroughly mix the reagent delivered by the dosing pump with the cyanide tailings in the reaction chamber, breaking down the contact barrier between the tailings particles and the reagent, and accelerating the harmless reaction process such as cyanide oxidation and heavy metal chelation. Compared with natural mixing or simple stirring, this design can significantly shorten the reaction time and increase the tailings processing capacity per unit time, allowing the device to adapt to larger-scale tailings processing needs. The double sealing design of the first sealing element and the second sealing cover greatly enhances the airtightness of the reaction chamber. The sealing design effectively prevents the leakage of highly toxic cyanide gas during the reaction process and avoids external impurities from entering the reaction chamber and affecting the treatment effect. This design avoids the safety risks of operators coming into contact with highly toxic substances from the source, and also prevents secondary pollution caused by cyanide leakage, meeting the dual requirements of environmental protection and safe production. The observation window allows operators to observe the mixing state, reaction progress, and material level in the reaction chamber in real time without opening the sealing cover. This reduces the risk of leakage caused by frequent opening of the sealing cover and makes the operation status more intuitive. The discharge pipe is equipped with a check valve, which not only quickly discharges the harmless tailings after treatment, but also prevents material backflow during the discharge process. This ensures smooth discharge and avoids backflow material interfering with the internal operation of the reaction chamber, reducing the complexity of equipment operation and maintenance. The display terminals for various parameters such as cyanide ions and pH are also included. The real-time display of values ​​and heavy metal concentrations, along with the PLC controller's data storage and comparison, not only facilitates operators in checking operating conditions at any time but also provides data support for subsequent process optimization. At the same time, the automated process from parameter detection and dosing control to stirring and reaction significantly reduces the need for manual intervention, decreases the labor intensity and human error of manual operation, and improves the stability and intelligence level of the equipment operation.

[0013] Preferably, the PLC controller is connected to a heavy metal concentration sensor, and the heavy metal concentration display is also connected to the heavy metal concentration sensor. The cyanide ion concentration, pH value, and heavy metal concentration sensors capture key parameters in real time, and the data is directly transmitted to the PLC controller and simultaneously visualized on the corresponding display, allowing operators to intuitively grasp the reaction conditions. The PLC controller automatically controls the start / stop and dosage of the dosing pump by comparing real-time data with preset thresholds, achieving "on-demand dosing." When the cyanide concentration exceeds the standard, the agent is automatically replenished; once the standard is reached, dosing is immediately stopped. This avoids waste due to excessive agent addition caused by manual experience and eliminates substandard treatment caused by insufficient dosing, significantly improving the accuracy and economy of harmless treatment. Preferably, the transmission end on one side of the drive motor is fixedly connected to the rotating rod, and a stirring roller is fixedly installed on the outside of the rotating rod. When the drive motor starts, it drives the rotating rod to rotate, which in turn drives the stirring roller to rotate, promoting thorough mixing of the agent and the gold ore cyanide tailings and accelerating the reaction.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] This invention relates to a reaction chamber used for the harmless treatment of gold ore cyanide tailings. A cyanide ion concentration sensor, a pH sensor, and a heavy metal concentration sensor capture core parameters such as cyanide ion concentration, pH value, dissolved oxygen, and heavy metal concentration in real time. The data can be directly fed back to a PLC controller and displayed on the cyanide ion concentration display, pH value display, and heavy metal concentration display, respectively. The PLC controller compares the collected data with preset thresholds and then controls the dosing pump to discharge the reagents. The dosing pump draws the reagents from the reagent tower into the reaction chamber through a first and second connecting pipe. The drive motor starts, driving the rotating rod to rotate, which in turn rotates the stirring roller, promoting thorough mixing of the reagents with the gold ore cyanide tailings and accelerating the reaction. The inclusion of a first sealing component and a second sealing cover increases the device's sealing performance. The observation window allows the user to easily observe the inside of the reaction chamber. The discharge pipe and check valve facilitate the discharge of the reagents.

[0016] This invention uses sensors to capture key parameters such as cyanide ion concentration, pH value, and heavy metal concentration in real time. The data is directly transmitted to the PLC controller and simultaneously visualized on the corresponding display, allowing operators to intuitively understand the reaction conditions. The controller automatically controls the start / stop and dosage of the dosing pump by comparing real-time data with preset thresholds, achieving "on-demand dosing." When the cyanide concentration exceeds the standard, the controller automatically replenishes the reagent; once the standard is reached, dosing stops immediately. This avoids waste due to excessive dosing caused by manual experience and eliminates substandard treatment caused by insufficient dosing, significantly improving the accuracy and economy of harmless treatment. The drive motor rotates the stirring roller, quickly and thoroughly mixing the reagent delivered by the dosing pump with the cyanide tailings in the reaction tank. This breaks down the contact barrier between tailings particles and reagents, accelerating the harmless treatment processes such as cyanide oxidation and heavy metal chelation. Compared to natural mixing or simple stirring, this design significantly shortens the reaction time and increases the tailings processing capacity per unit time, allowing the device to adapt to larger-scale tailings treatment needs. The double-sealing design of sealing element one and sealing cover two further enhances the safety and efficiency of the process. The enhanced sealing of the reaction chamber effectively prevents the leakage of highly toxic cyanide gas during the reaction process and avoids external impurities from entering the chamber and affecting the treatment effect. This design eliminates the safety risk of operators coming into contact with highly toxic substances from the source, and also prevents secondary pollution caused by cyanide leakage, meeting the dual requirements of environmental protection and safe production. The observation window allows operators to observe the mixing state, reaction progress, and material level inside the reaction chamber in real time without opening the sealing cover. This reduces the risk of leakage caused by frequent opening of the sealing cover and makes the operation status more intuitive. The discharge pipe with a check valve design not only quickly discharges the treated harmless tailings but also prevents material backflow during the discharge process, ensuring smooth discharge while avoiding interference from backflow material on the internal operation of the reaction chamber, reducing the complexity of equipment operation and maintenance. The display terminals for various parameters such as cyanide ions and pH are also included. The real-time display of values ​​and heavy metal concentrations, along with the PLC controller's data storage and comparison, not only facilitates operators in checking operating conditions at any time but also provides data support for subsequent process optimization. At the same time, the automated process from parameter detection and dosing control to stirring and reaction significantly reduces the need for manual intervention, decreases the labor intensity and human error of manual operation, and improves the stability and intelligence level of the equipment operation.
