Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of bauxite beneficiation processing, in particular to an automatic control production system for desilication of high-silicon bauxite. BACKGROUND

[0002] Bauxite is the main raw material for the aluminum industry. With the rapid development of the aluminum industry in China, the demand for aluminum raw materials is increasing. As bauxite is continuously mined, high-aluminum-silicon ore and low-sulfur bauxite resources are depleted. In order to ensure the efficient development of bauxite resources and the sustainable development of the national economy, the comprehensive utilization of low-grade high-silicon bauxite in production and processing is gradually being developed and utilized. Due to the presence of silicon in high-silicon bauxite, the content of harmful impurities such as silicon, sulfur, and iron is too high when producing alumina by combined or sintering method, which not only complicates the alumina production process but also increases the alkali consumption, power consumption, and production cost. Therefore, high-silicon bauxite needs to be pretreated by desilication. At present, the main method for desilication of high-silicon bauxite is flotation desilication.

[0003] For example, the patent document with publication number CN 117138967 A discloses a method for flotation desulfurization and desilication of high-sulfur high-silicon bauxite. The method includes grinding and slurry conditioning of bauxite to obtain a slurry. After adjusting the pH of the slurry to 9.5-10.5, reverse flotation desulfurization is performed using a yellow compound, a hydroxamic acid compound, and a non-polar oil as a collector I, and a sulfate as an activator to obtain a sulfur rough concentrate and a desulfurization tailings. After adjusting the pH of the desulfurization tailings to 9.5-10.5, positive flotation desilication is performed using a fatty acid soap compound and a hydroxamic acid compound as a collector II to obtain an aluminum ore rough concentrate and tailings. After adjusting the pH of the aluminum ore rough concentrate to 9.5-10.5, a silicate inhibitor and a sulfide ore inhibitor are added for cleaning to obtain an aluminum ore concentrate and a cleaning tailings. This technical solution achieves desulfurization and desilication of high-sulfur high-silicon bauxite, and the obtained sulfur concentrate has high purity, the aluminum ore concentrate has high aluminum-silicon ratio and low sulfur content.

[0004] Although the above technical solution can achieve desulfurization and desilication of high-silicon bauxite, there are still the following problems in the desulfurization and desilication process:

[0005] 1. In order to more effectively achieve the monomer dissociation of the target mineral, the mineral is usually ground finer before processing. Fine minerals are easy to adhere to bubbles, which reduces the floatability of coarse particles, worsens the selectivity, and affects the separation effect, making it difficult to separate by flotation, affecting the concentrate grade, and making it difficult for the desilication effect of conventional bubble flotation process to meet the requirements of aluminum ore processing.

[0006] 2. During the desiliconization process of bauxite, the flotation liquid level, air intake, spray water and other parameters need to be precisely controlled and adjusted. At present, during the desiliconization process, it is impossible to accurately adjust the various parameters according to the actual needs of the desiliconization process, which restricts the flotation product quality, stable yield and production scale of the flotation process working in a certain stable state; resulting in insufficient economic conditions and restricting the continued development of technology. Summary of the Invention

[0007] The present invention aims to provide an automated control production system for desiliconization of high-silicon bauxite, so as to solve the technical problem in the prior art that the flotation desiliconization processing effect cannot meet the needs of bauxite production.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: an automated control production system for desiliconization of high-silicon bauxite, comprising a desiliconization unit, a monitoring unit, and a control unit. The desiliconization unit comprises a flotation column, a separation chamber is provided in the flotation column, and a feed port is provided on one side of the flotation column; the feed port is connected to a delivery pump through a bauxite slurry delivery pipe; a first output port and a second output port are provided on the separation chamber, the first output port is used to output separated tailings, and the second output port is used to output separated concentrate; the separation chamber is also connected to a bubble generator, and the bubble generator is used to deliver bubbles into the separation chamber;

[0009] The monitoring unit includes a liquid level monitoring part, an inflation monitoring part and a feed monitoring part. The liquid level monitoring part is used to monitor the liquid level in the separation chamber, the inflation monitoring part is used to monitor the amount of air input by the bubble generator, and the feed monitoring part is used to monitor the feed amount of the feed port.

[0010] The control unit is used to adjust various parameters of the flotation column during the flotation desiliconization process according to various monitoring results of the flotation column by the monitoring parts of the monitoring unit.

[0011] The principles and advantages of this solution are as follows: During the desiliconization process of bauxite, the bauxite slurry is transported to a separation chamber, and reagents and other separation materials are added to the separation chamber. The bauxite slurry is then separated and processed in the separation chamber, resulting in concentrate and tailings, thus completing the desiliconization process of the bauxite. During the desiliconization and separation process of the bauxite, the liquid level, air intake, and feed volume during the process are dynamically monitored by a monitoring unit. The control unit dynamically adjusts the liquid level, air intake, and feed volume during the desiliconization process based on the monitoring unit's monitoring results, ensuring that various parameters of the desiliconization process are maintained within a preset range.

[0012] In the scheme, during the desilication process of bauxite, the liquid level of bauxite is dynamically monitored and adjusted, so that the liquid level, the air charge and the feed size in the flotation column can be accurately controlled during the flotation production and processing, the liquid level in the flotation column is kept stable, the matching degree of the air charge and the feed size with the actual processing condition is improved, the recovery rate of useful minerals is improved, and the effect of flotation processing is ensured. And the monitoring unit and the control unit automatically complete the monitoring and adjustment of various parameters in the desilication process, so that the desilication processing equipment can run safely and stably with high yield and high quality for a long period of time, and the production can be maintained in a normal or best process operation state.

[0013] Preferably, as an improvement, the liquid level monitoring part comprises a floating ball, a reflecting plate is arranged above the top of the floating ball, the reflecting plate is connected with the floating ball through a connecting rod, and the floating ball is used to drive the reflecting plate to move up and down; a first sensor is arranged above the reflecting plate, and the first sensor is used to monitor the height position of the reflecting plate. The reflecting plate is driven to move up and down by the floating ball, the position of the reflecting plate is adjusted according to the change of the liquid level, the liquid level height can be accurately monitored through the foam layer, the interference of the foam layer during liquid level monitoring is reduced, and the position of the reflecting plate is monitored by the sensor, so that the height change of the reflecting plate can be accurately measured in time when the position of the reflecting plate changes.

[0014] Preferably, as an improvement, a limiting tube is arranged between the reflecting plate and the floating ball, and the connecting rod penetrates through the limiting tube, so that the position of the connecting rod in the horizontal direction is limited. When the reflecting plate is driven to move by the floating ball, the position of the reflecting plate in the horizontal direction can be limited and fixed, so that the reflecting plate is prevented from deviating in the horizontal direction during movement, the deviation of the reflecting plate in transmitting the liquid level height position is avoided, and the accuracy of liquid level height monitoring is affected.

[0015] Preferably, as an improvement, control valves are arranged on the first output port and the second output port respectively, and the control valves are used to control the opening and closing size of the first output port and the second output port. The opening and closing size of each output port can be controlled and adjusted by the control valve, so that the output speed of each output port can be dynamically adjusted according to the actual demand during the desilication process, and the output speed in the processing process can be matched with the actual demand.

[0016] Preferably, as an improvement, the control unit adjusts the opening and closing size of the control valves on the first output port and the second output port according to the monitoring result of the liquid level monitoring part.

[0017] Preferably, as an improvement, the control unit controls the liquid level and adjusts the air charge of the bubble generator. When the liquid level changes, the air charge can be adjusted in time to ensure that the bauxite is separated by the sufficient amount of foam that wraps the ore minerals, and the desilication operation proceeds normally.

[0018] Preferably, as an improvement, the control unit adjusts the air charge of the bubble generator according to the monitoring results of the liquid level monitoring unit and the air charge monitoring unit. By monitoring and controlling the air flow rate in the bubble generator, it is avoided that the air flow rate is too small, causing the foam area to easily form a dead zone, or the air flow rate is too large, causing the wrapped ore minerals to carry too many aluminosilicate gangue minerals, affecting the flotation effect of the bauxite.

[0019] Preferably, as an improvement, the control unit also performs fuzzy control on the liquid level and the air charge of the bubble generator during the desilication process. During the desilication process, the control unit can constantly fine-tune the liquid level and the air charge to ensure that the thickness of the foam layer can match the actual demand, and the desilication process proceeds normally.

[0020] Preferably, as an improvement, the control unit also controls and adjusts the delivery amount of the delivery pump according to the monitoring results of the feed monitoring unit. By monitoring the feed amount, the amount of feed during the desilication process is improved to be appropriate and stable, avoiding that the size of the feed amount affects the balance of the flotation system and the consumption of reagents, and avoiding that the feed amount is too small or too large, affecting the separation processing time and efficiency.

The specific structure of the bubble generator 501 is a prior art and will not be described here.

[0030] The control valves 6 are arranged on the first output port, the second output port, and the circulating output port, respectively. The control valves 6 are used to control the opening and closing sizes of the first output port, the second output port, and the circulating output port, so as to realize the adjustment of the discharging amounts of the first output port, the second output port, and the circulating output port. Specifically, the opening and closing sizes of the first output port, the second output port, and the circulating output port are adjusted by the electromagnetic control valves 6. The specific content of adjusting the opening and closing sizes of the output ports by the electromagnetic control valves 6 is a prior art and will not be described here. The opening and closing sizes of the output ports can be controlled and adjusted by the control valves 6. This is convenient for dynamically adjusting the output speeds of the output ports according to actual needs in the desiliconization process, so as to ensure that the output speeds in the process match the actual needs.

[0031] As shown in FIG. 1, the flotation separation chamber 103 is arranged on the top of the cyclone separation chamber 104. Figure 3As shown, the monitoring unit comprises a liquid level monitoring part 7 for monitoring the liquid level in the flotation separation chamber 103, wherein the liquid level monitoring part 7 comprises a float ball 701, the density of the float ball 701 is less than the density of the ore pulp in the flotation separation chamber 103, that is, the float ball 701 can float on the liquid surface in the flotation separation chamber 103. A reflecting plate 702 is arranged at the top of the flotation separation chamber 103, and the reflecting plate 702 is connected with the float ball 701 through a connecting rod 703, the float ball 701 is used to move up and down according to the liquid level of the ore pulp in the flotation separation chamber 103, and drives the reflecting plate 702 to move up and down. A first sensor is arranged above the reflecting plate 702, the first sensor is used to monitor the height position of the reflecting plate 702, wherein the first sensor can be an infrared sensor, an ultrasonic sensor or other distance monitoring sensor, and preferably in the embodiment, the first sensor is an ultrasonic distance sensor with a model of URM08-RS485, and the specific content of monitoring the position of the reflecting plate 702 through ultrasonic waves is prior art, which will not be described here. The reflecting plate 702 is driven to move up and down by the float ball 701, so as to adjust the position of the reflecting plate 702 according to the change of the liquid level, so that the liquid level can be accurately monitored through the foam layer, and the interference of the foam layer during liquid level monitoring is reduced; and the position of the reflecting plate 702 is monitored by the sensor, so that when the position of the reflecting plate 702 changes, the height change of the reflecting plate 702 can be accurately and timely measured.

[0032] A limiting tube 704 is arranged between the reflecting plate 702 and the float ball 701, the limiting tube 704 is a hollow tube, the extending direction of the limiting tube 704 is consistent with the extending direction of the connecting rod 703 between the reflecting plate 702 and the float ball 701, and the outer side wall of the limiting tube 704 is fixedly connected with the inner wall of the flotation separation chamber 103 through bolts or welding; the connecting rod 703 penetrates through the limiting tube 704, and the limiting tube 704 is used to limit the position of the connecting rod 703 in the horizontal direction. When the float ball 701 drives the reflecting plate 702 to move, the position of the reflecting plate 702 in the horizontal direction can be limited and fixed, so as to avoid the horizontal deviation of the reflecting plate 702 during movement, which causes the deviation of the liquid level position transmitted by the reflecting plate 702, and affects the accuracy of the liquid level monitoring.

[0033] The monitoring unit further comprises an air charging monitoring part for monitoring the amount of air delivered to the separation cavity 102. Specifically, when monitoring the amount of air delivered to the separation cavity 102, the air charging monitoring part monitors the flow rate of the air input into the bubble generator 501, analyzes the amount of air delivered to the separation cavity 102 by the bubble generator 501 according to the monitoring of the flow rate of the air input into the bubble generator 501. When monitoring the flow rate of the air input into the bubble generator 501, a pressure sensor can be selected to monitor the air pressure of the input air. In the present embodiment, a gas pressure sensor of model AP-C30 is preferably selected to monitor the pressure of the input air, and in other embodiments, other sensors can also be selected to monitor the amount of input air. By monitoring the input air of the bubble generator 501, the input air can be accurately monitored when the ore pulp is processed by flotation with the foam, and the comprehensiveness of the flotation processing monitoring parameters is improved.

[0034] The monitoring unit further comprises a feed monitoring part for monitoring the amount of bauxite raw material delivered to the separation cavity 102 by the feed inlet. Specifically, a flowmeter is arranged on the feed inlet to monitor the flow rate of the bauxite passing through the feed inlet. In the present embodiment, an electromagnetic flowmeter of model KR-DC is preferably selected to monitor the amount of bauxite feed. By monitoring the feed, the amount of input ore can be effectively monitored during the flotation processing, and the input bauxite can be matched with the actual demand.

[0035] The control unit is electrically connected with the liquid level monitoring part 7, the air charging monitoring part and the feed monitoring part of the monitoring unit. The control unit is used to obtain the monitoring results of each monitoring part of the monitoring unit on the flotation column 1, and control and adjust each parameter of the flotation column 1 during the desiliconization processing. The control unit can be a single-chip microcomputer, a microprocessor or the like. In the present embodiment, a high-performance MCU single-chip microcomputer of model STM32F207 is preferably selected to control the desiliconization processing of the flotation unit.

[0036] The control unit is used for controlling the liquid level height in the flotation column 1 according to the monitoring result of the monitoring unit, and is electrically connected with the electromagnetic valves on the first output port, the second output port and the circulating output port. The control unit adjusts the opening and closing size of the first output port and the second output port according to the monitoring result of the liquid level monitoring part 7 in the monitoring unit. Specifically, when the liquid level monitoring part 7 monitors that the liquid level height in the flotation cavity is greater than a preset value, the control unit sends a command to control the control valve 6 on the first output port and the second output port to increase the opening degree, so that the output amount of the first output port or the second output port is increased, and the liquid level in the separation cavity 102 can be lowered. When the liquid level monitoring part 7 monitors that the liquid level height in the flotation cavity is less than the preset value, the control unit sends a command to control the control valve 6 on the first output port and the second output port to decrease the opening degree, so that the output amount of the first output port or the second output port is decreased, and the liquid level in the separation cavity 102 can be raised, so that the height in the separation cavity 102 can be kept within a reasonable range.

[0037] The control unit is also used for adjusting the air amount delivered to the separation cavity 102 according to the monitoring content of the liquid level monitoring part 7 and the aeration monitoring part. Specifically, when the air amount is adjusted, the control unit analyzes the size of the input air amount matched with the liquid level according to the liquid level data monitored by the liquid level monitoring part 7, and compares the input air amount corresponding to the actual air input pressure monitored by the aeration monitoring part with the size of the required input air amount. When the actual input air amount is less than the size of the required input air amount, the control unit sends a command to increase the air intake amount of the bubble generator 501. When the actual input air amount is greater than the size of the required input air amount, the control unit sends a command to decrease the air intake amount of the bubble generator 501. The specific content of analyzing the air amount size according to the liquid level height monitored by the liquid level monitoring part 7 is prior art, which will not be described here. As the most flexible and sensitive parameter in the control of the flotation column 1, the air flow rate of the bubble generator 501 is monitored and controlled to avoid too small air flow rate, which causes the foam area to easily gather and form a dead zone, or too large air flow rate, which causes the flotation column 1 to overflow with foam, affecting the flotation effect of the bauxite.

[0038] The control unit adjusts the air amount while controlling the liquid level height. Specifically, when the control unit monitors that the liquid level height in the separation cavity 102 changes, the control unit adjusts the air amount size while adjusting the control valve 6, so that the air amount input by the bubble generator 501 can match the actual demand. When the liquid level height changes, the air amount can be adjusted in time to ensure that enough foam quantity is formed in the separation cavity 102 to wrap and separate the bauxite, and ensure the normal operation of the desiliconization operation.

[0039] The control unit is also used for fuzzy control of the liquid level and the air charge when adjusting the liquid level and the air charge, that is, in the process of desilication of the bauxite, the control unit dynamically and fuzzily controls the control valve 6 and the air charge of the bubble generator 501 through a fuzzy control algorithm, so that the liquid level in the separation chamber 102 and the air charge can be maintained within a preset range, and the specific content of the fuzzy control algorithm is a prior art and will not be described here. In the desilication process, the control unit can continuously fine-tune the liquid level and the air charge, ensure that the thickness of the foam layer can match the actual demand, and ensure the normal progress of the desilication process.

[0040] The control unit is also used for controlling the feed amount. Specifically, a preset range value of the preset feed amount is stored in the control unit. The control unit compares the actual feed amount monitored by the feed monitoring unit with the preset feed amount value. When the actual feed amount value is greater than the preset feed amount, the feed speed is too fast, and the control unit issues an instruction to adjust the power of the delivery pump on the bauxite slurry delivery pipe 2 to reduce the feed speed. When the actual feed amount value is less than the preset feed amount, the feed speed is too slow, and the control unit issues an instruction to adjust the power of the delivery pump on the bauxite slurry delivery pipe 2 to increase the feed speed. The size of the feed amount can match the actual demand. By monitoring the feed amount, the appropriate and stable feed amount in the desilication process is improved, avoiding the influence of the size of the feed amount on the balance of the flotation system and the consumption of reagents, and avoiding too small or too large feed amount, affecting the separation processing time and efficiency.

[0041] The specific implementation process is as follows:

[0042] In the process of desilication of the bauxite, the bauxite slurry is delivered to the separation chamber 102, and the separation required materials such as reagents are added in the separation chamber 102. The bauxite slurry is subjected to cyclonic separation and flotation separation processing in the separation chamber 102, so that the bauxite slurry is separated into concentrate and tailings after separation, and the desilication of the bauxite is completed. In the process of desilication separation of the bauxite, the monitoring unit dynamically monitors the liquid level, the air charge and the feed amount in the processing process, and the control unit dynamically adjusts the liquid level, the air charge and the feed amount in the desilication process according to the monitoring results of the monitoring unit, so that each parameter in the desilication process can be maintained within a preset range.

[0043] Compared with the prior art, in the scheme, in the desilication process of bauxite, the liquid level of bauxite is dynamically monitored and adjusted, so that the liquid level, the air charge and the feed amount in the flotation column 1 can be accurately controlled in the flotation production process, the matching degree of the air charge and the feed amount with the actual processing condition is improved, the stability of the flotation processing effect is improved, the recovery rate of useful minerals is improved, and the effect of the flotation processing is ensured. And the monitoring unit and the control unit automatically complete the monitoring and adjustment of various parameters in the desilication process, so that the desilication processing equipment can be safely operated with high yield, high quality and long period, and the production can be maintained in the normal or best process operation state.

[0044] It should be pointed out that for those skilled in the art, without departing from the technical scheme of the present application, a number of modifications and improvements can be made, which should be considered as the protection scope of the present application, which will not affect the effect and practicality of the present application. The protection scope claimed in the present application should be subject to the content of its claims, and the specific implementation mode and the like recorded in the specification can be used to explain the content of the claims.
