Description

Technical Field

[0001] This utility model relates to the field of single-layer thickener technology, specifically to an intelligent operating device for a single-layer thickener. Background Technology

[0002] In the cyanide workshop, the single-layer thickener in the filtration section operates by a motor driving a tire through a reducer, which makes the single-layer thickener run at a constant speed. The power supply is provided to the motor by a sliding contact line through a conductor.

[0003] Problems: Rubber tires are prone to slipping on iron plates during heavy rain and snow due to reduced friction. Operators may not notice this in time, leading to prolonged slippage and ore accumulation in single layers. Frequent ups and downs of these single layers at night pose safety hazards due to working at heights.

[0004] 1. Prolonged use of the conductor causes carbon brush wear and poor contact between the sliding contact line and the conductor, which can easily lead to motor burnout due to phase loss. Operators may not be able to detect this in time, and prolonged shutdown can result in single-layer ore accumulation.

[0005] 2. Summer rain and winter snowfall can reduce the friction between the thickener drive tires and the iron plate, causing tire slippage, which can lead to single-layer ore sitting for a long time.

[0006] 3. If the tires slip, the operator will have to manually push the thickener while it is running, and at the same time, sand will be sprinkled on the slipping area to increase friction, which poses a safety hazard of mechanical injury and working at height. Utility Model Content

[0007] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0008] Therefore, the purpose of this utility model is to provide an intelligent operating device for a single-layer thickener, which can improve the stability of equipment operation, reduce downtime due to malfunctions, reduce the risk of manual intervention, enhance safety, prevent single-layer ore accumulation, ensure production continuity, adapt to harsh environments, and improve all-weather operation capability.

[0009] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0010] An intelligent operation device for a single-layer thickener, comprising:

[0011] A programmable logic controller (PLC) is used to receive and process operating status signals and control motors and auxiliary equipment.

[0012] The underspeed slippage detection module is used to perform real-time monitoring of tire speed and send a signal to the PLC when tire slippage is detected.

[0013] The wireless transmission switch is used to send an alarm signal to the operation site when the thickener stops abnormally or malfunctions.

[0014] The automatic friction-enhancing system includes a sand bucket, a push rod actuator, and a sand guide groove located in front of the tire, which is used to automatically spread sand to increase friction when the tire slips.

[0015] The real-time monitoring system, including a wireless transceiver and a display screen, is used to display the operating trajectory and fault status of the thickener in real time.

[0016] The positioning and correction module is used to correct the operating position of the thickener to ensure the accuracy of signal transmission;

[0017] The phase loss protector is used to detect phase loss faults caused by wear of the conductor carbon brushes and trigger an alarm.

[0018] As a preferred embodiment of the intelligent operation device for a single-layer thickener described in this utility model, the underspeed slippage detection module includes a Hall sensor connected to the tire. When no tire rotation signal is detected within 2 seconds, the PLC controls the motor to reverse for 20 seconds and starts the automatic friction enhancement system.

[0019] As a preferred embodiment of the intelligent operation device for a single-layer thickener described in this utility model, the sand bucket push rod of the automatic friction enhancement system adopts a pneumatic or electric actuator. The PLC controls the solenoid valve and relay to open and close the push rod, so that the sand flows along the sand guide groove to the contact surface between the tire and the iron plate.

[0020] As a preferred embodiment of the intelligent operation device for a single-layer thickener described in this utility model, the real-time monitoring system adopts a PTZ sharing mode, and transmits the operation data to the remote monitoring platform via wireless transmission to realize remote operation and monitoring.

[0021] In a preferred embodiment of the intelligent operation device for a single-layer thickener described in this utility model, the PLC programmable controller is programmed to execute the following control logic:

[0022] When tire slippage is detected, the control motor reverses for 20 seconds and activates the automatic friction enhancement system.

[0023] If the same position slips three times in a row, a level two alarm will be triggered, including audible and visual alarms and remote alarm signals.

[0024] When the phase loss protector is triggered, it immediately cuts off the power supply and issues an alarm signal.

[0025] As a preferred embodiment of the intelligent operation device for a single-layer thickener described in this utility model, the positioning and correction module includes at least one physical positioning point for performing correction of the thickener's operating trajectory to ensure the accuracy of wireless signal transmission.

[0026] As a preferred embodiment of the intelligent operation device for a single-layer thickener described in this utility model, the wireless transmission switch adopts an industrial-grade wireless communication module to ensure stable transmission of alarm signals even under adverse weather conditions.

[0027] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0028] Improve equipment operational stability and reduce downtime due to malfunctions:

[0029] Automatically detects and adjusts for slippage. The underspeed slippage detection module monitors the tire speed in real time. Once slippage is detected (e.g., no rotation signal within 2 seconds), the PLC immediately controls the motor to reverse for 20 seconds and simultaneously starts the automatic friction-enhancing system to spread sand, quickly restoring friction and preventing ore accumulation caused by prolonged slippage.

[0030] Phase loss protection: When the carbon brushes of the conductor wear out and cause a phase loss, the phase loss protector immediately cuts off the power supply and alarms to prevent the motor from burning out and extend the equipment life.

[0031] Reduce the risk of human intervention and improve safety:

[0032] To reduce high-altitude operations, traditional methods require manual pushing of carts or spreading of sand, which pose risks such as falls from heights and mechanical injuries; this device automatically handles slippage, reducing manual intervention and lowering safety hazards.

[0033] Remote monitoring and alarm: Through the real-time monitoring system and wireless transmission switch, operators can keep track of the equipment status in the control room or remote platform in real time and immediately alarm when a fault occurs, so as to avoid production stoppage or equipment damage due to failure to detect faults in time.

[0034] To prevent single-layer ore accumulation and ensure continuous production:

[0035] Rapid response mechanism: When slippage or shutdown occurs, the system automatically handles the situation and issues an alarm, avoiding slurry deposition due to delays in manual response, reducing cleaning costs and production interruptions;

[0036] Three consecutive slippage alarm upgrade: If the same location slips three times in a row, a level 2 alarm (audio-visual + remote notification) will be triggered to remind maintenance personnel to conduct key inspections and prevent repeated failures.

[0037] Adapt to harsh environments and enhance all-weather operation capabilities:

[0038] The rain and snow resistant design features an automatic friction-enhancing system that automatically spreads sand during rain and snow to ensure friction between the tires and the steel plate, reducing the impact of weather on production.

[0039] Stable wireless communication employs industrial-grade wireless transmission to ensure stable data transmission even in harsh environments such as humidity and low temperatures. Attached Figure Description
