Description
Technical field
Underground coal mine emulsion pump box water inlet system is the utility model is related to, specifically a kind of underground coal mine emulsion
Pump box water inlet automatic control system.
Background technology
At present, domestic underground coal mine emulsion pump box water inlet typically uses manual ball check valve, by manually opening and closing
Close, be not carried out automatically controlling.General fully mechanized mining team arranges 1 driver to guard pumping plant, when need to add water, opens ball check valve, when
After water tank is filled it up with, ball check valve is closed.This often forgets to switch stop valve because of driver inattention or being too busy to do it.Work as work
The unexpected bombing in face or evaporating, emitting, dripping or leaking of liquid or gas are serious, the increase of working face water consumption and driver could not in time plus water, emulsion pump box water level is fast
Speed declines, and when water level is less than pipette, pumping plant is emptied, and pumping plant will be caused badly damaged.Conversely, when water inlet ball check valve
Fail to close in time, continue to supply water, water tank can be caused to overflow water, crossheading ponding, influence environment on coalface, waste water and oil emulsion.
In addition, fully-mechanized mining working water treatment facilities has strict demand to intake pressure, superpressure can cause water treatment facilities to damage
It is bad, so mine water has to pass through pressure-reducing valve decompression before entering water treatment facilities.It is all machinery to be currently installed on pressure-reducing valve
Pressure gauge, artificial reading, without overpressure alarm function, when pressure-reducing valve break down and pumping plant driver could not the processing of discovery in time,
Easily cause water treatment facilities damage.
Utility model content
The purpose of this utility model is low in order to solve emulsion pump box water inlet auto-control degree in the prior art
Defect, there is provided a kind of underground coal mine emulsion pump box intakes automatic control system to solve the above problems.
To achieve these goals, the technical solution of the utility model is as follows：
A kind of underground coal mine emulsion pump box water inlet automatic control system；Robot control system(RCS) include controller, proportional pressure-reducing valve,
Pressure sensor, coarse filter, magnetic valve, water treatment facilities, liquid level sensor；It is the proportional pressure-reducing valve, pressure sensor, thick
Filter, magnetic valve, water treatment facilities are installed on inlet pipeline, and liquid level sensor is arranged in emulsion pump box；Mine
Water enters emulsion pump after the proportional pressure-reducing valve, pressure sensor, coarse filter, magnetic valve, water treatment facilities successively
Case；
The liquid level sensor gathers the liquid level information in emulsion pump box and is transferred to controller, and controller is according to liquid level
Information control magnetic valve opens and closes；The controller obtains the pressure information that pressure sensor collects, and is set when pressure information reaches
When determining the upper limit, controller control alarm sends alarm signal.
Preferably, the magnetic valve is two-position two-way solenoid valve.
Preferably, the bottom limit level information and upper limit level information in the liquid level sensor collection emulsion pump box.
The utility model compared with prior art, has the advantages that：
Robot control system(RCS) provided by the utility model improves fully-mechanized mining working liquid-supplying system automaticity, reduces worker's work
Intensity, protect system equipment.
The emulsion pump box automaton can automatically control entering water electromagnetic valve and open according to liquid case SEA LEVEL VARIATION situation
Stop, complete automatic watering and cut off the water.
Monitoring water treatment facilities intake pressure in real time, judges whether proportional pressure-reducing valve is intact, possesses alarm and auto water stopping
Function, play protection water treatment facilities.
Realize unattended, mitigation worker's labor intensity, raising operating efficiency.
Solve the problems, such as that emulsion pump box overflows water destruct working environment and wasted water and oil emulsion.
Solve the problems, such as or emulsion pump box water shortage causes pumping plant to be emptied the damage pump housing.
Brief description of the drawings
Fig. 1 is the utility model overall structure diagram；
Fig. 2 is operation principle block diagram of the present utility model.
Embodiment
The effect of to make to architectural feature of the present utility model and being reached, has a better understanding and awareness, to compared with
Good embodiment and accompanying drawing coordinate detailed description, are described as follows：
As shown in figure 1, emulsion pump box water inlet automatic control system mainly by PLC 1, two-position two-way solenoid valve 2,
The composition such as liquid level sensor 3, pressure sensor 4, buzzer 5 and associated pipe 6, cable.
One liquid level sensor 3 is installed in emulsion pump box, pacified on mine water inlet pipeline 6 (behind coarse filter)
Two-position two-way solenoid valve 2 is filled, ball check valve is substituted with two-position two-way solenoid valve 2.One is installed in the output end of proportional pressure-reducing valve 7
Pressure sensor 4, substitutes mechanical pressure gauge, and pressure sensor 4 sets pressure as 1.5MPa (adjustable).Liquid level sensor 3, pressure
Sensor 4, magnetic valve 2, overpressure alarm buzzer 5 pass through cable connection to PLC 1.
As shown in Figure 2：Mine water water inlet tube pressure is 6.3MPa, by proportional pressure-reducing valve 7 (1：4), pressure is reduced to
1.5MPa, enter water treatment facilities 9, mine water after treatment, into breast by coarse filter 8, two-position two-way solenoid valve 2
Change liquid pump case 10.Feed liquor needs manual adjustment first, and when liquid level touches the bottom (bottom limit level), liquid level sensor 3 is by liquid
Low liquid level signal is transmitted to PLC 1 in case.PLC 1 controls magnetic valve 2 to open according to setting program by relay K1
Open, supplied water to pump box 10；When liquid level rises to peak (upper limit level), high level signal is transmitted to PLC by liquid level sensor
Controller 1, PLC are closed to close by Control magnetic valve 2 and supplied water, so as to realize that water inlet is automatic according to setting program
Control.
Pressure sensor 4 is arranged on the low-pressure end of proportional pressure-reducing valve 7, and pressure sensor 4 gathers pressure signal, pressure transmitter
Pressure signal is converted into the recognizable signal of PLC 1 by 41 is transmitted to PLC 1.Because setting pressure sensor 4 is
1.5MPa (adjustable), when the pressure of pressure sensor 4 is more than 1.5MPa, PLC 1 closes magnetic valve 2, stops supplying water, together
When, buzzer 5 is alarmed, and reminds user proportional pressure-reducing valve 7 failure to be present, it is necessary to repair, so as to protect water treatment facilities 9 from
It is impaired.
The advantages of general principle of the present utility model, principal character and the utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
Simply principle of the present utility model, the utility model also has respectively on the premise of the spirit and scope of the utility model is not departed from
Kind changes and improvements, these changes and improvements are both fallen within claimed the scope of the utility model.The requires of the utility model
Protection domain defined by appended claims and its equivalent.
