Example Embodiment

[0041] Example 1

[0042] Such as figure 1 , figure 2 As shown, the intelligent current detection spray system of the belt conveyor includes a spray pipeline arranged above the belt of the belt conveyor, a plurality of solenoid valves arranged on the spray pipeline, and an electrical control system. The electrical control system is composed of a power supply, an intelligent current detector, a current transformer or an I / O board of a frequency converter that obtains a current signal reflecting the actual load of the belt drive motor, a spray circuit and a connecting wire, the current transformer or The output end of the inverter I / O board is electrically connected to the input module of the intelligent current detector through the current input channel. The spray circuit is composed of a power supply, an output contact K electrically connected to the output module of the intelligent current detector, and an output contact K series maintenance / spray switch SA, a test button conn...

Example Embodiment

[0063] Example 2

[0064] See Figure 6-a to Figure 6-c The spray pipeline adopts a pipeline solenoid valve arranged along the length of the belt conveyor, and there is only a first spray section in the full length direction, and the relay is an intermediate relay K1 that controls the pipeline solenoid valve. When the full-length spray section is used, the start time of the intermediate relay K1 that controls the pipeline solenoid valve is Tsd1, that is

[0065] Tsd1=[(15%~30% )L÷v]+ΔT

[0066] In the formula, L is the total length of the belt of the belt conveyor, (15%~30%) L means that the material carried by the belt conveyor is 15%-30% of the total length of the belt from the tail leakage to the distance, and v is the belt speed and delay time ΔT=10s, set for the internal program timer of the intelligent current detector, used to avoid the starting time of the drive motor and prevent external signal interference, to avoid the sprinkler circuit from malfunctioning. In this emb...

Abstract

The invention relates to a belt conveyor intelligent current detection spraying system and a control method. Through a current transformator or a frequency converter I/O (input/output) board, a standard current signal reflecting an actual load of a driving motor is accessed into an intelligent current detector, the intelligent current detector uses the difference between the idle load current and the load current of the driving motor to determine a current set value Isd, through calculation, when the actual load current I is greater than or equal to the Isd, the intelligent current detector switches on a spraying circuit for implementing the spraying in a time delay manner through an output module, the time delay time is delta T, the actual current detected by the intelligent current detector needs to continuously meet the requirement that I is greater than or equal to the Isd in the time of the delta T, when the actual load current I is smaller than the Isd, the intelligent current detector switches off the spraying circuit through the output module, and the spraying operation is stopped. The application range is wide, the advantages of low investment, good effect, high practicability, high intelligence and water resource saving are achieved, the surrounding environment is effectively protected, the occurrence rate of anthracosis is reduced, and the safe and civilized production is ensured.

Description

technical field [0001] The invention relates to a treatment method for various dust points during the belt transportation of ore in metal mine mining and beneficiation process, in particular to an intelligent current detection spray system and a control method of a belt conveyor. Background technique [0002] At present, in the ore mining and dressing system, the working process of the ore crusher and the belt conveyor will generate a large amount of dust, which will affect the quality of the surrounding environment. Dust pollution in indoor environment, more importantly, dust contains silicon element, which is the source of occupational disease - silicosis. [0003] The existing dust reduction methods usually use sprinklers for dust reduction, and a few of them use water spray pipes on both sides of the mine road to reduce dust, but there are problems of poor practicability, low intelligence, poor dust reduction effect and waste of water resources. If the amount of water s...
