Working principle：
The stirring main circuit breaker QF1 of blender major loop, the main circuit breaker QF2 in water pump major loop are closed first, then are closed
Upper fuse FU1 and FU2；F in last power turn-on signal lamp circuit, if any electricity, then power lamp HL is bright；
Blender stirs the course of work：After a variety of materials are packed into hopper according to a certain percentage, stirring conversion is opened
Concern changes to mixing position, i.e. contact 1 and 2, contact 5 and 6, contact 9 is connected with 10, then the power supply for stirring motor at this time is pressed
It is arranged according to L1, L2, L3 phase sequence；Stirring start button SB2 is then pressed, the control circuit of blender is connected at this time, stirs owner
The coil of contactor KM obtains the voltage operation of 380V, makes the normally opened contact closure self-insurance for stirring main contactor KM, maintains stirring
Main contactor KM work, stirring main contactor KM main contact be closed at, at this time stir motor M1 winding obtain L1,
The three-phase 380V current and power supply of L2, L3 phase sequence, starting operating, agitator just transfers to rotate in the forward direction because stirring motor at this time, to
After agitator works well, hopper is risen to bit flipping, hopper leads mixture by clutch operating handle by operator
Enter in the agitator of normal operation and be stirred, after hopper landing, starts water pump water adding in time；
Pump working process：The time definite value for first setting the time relay presses water pump start button SB4, at this time water
The control circuit of pump is connected, and the coil of water pump main contactor KM1 obtains the voltage operation of 380V at this time, makes water pump main contactor
The normally opened contact of KM1 is closed self-insurance, maintains water pump main contactor KM1 work, and the main contact of water pump main contactor KM1 closes simultaneously
It closes, pump motor M2 obtains the three-phase 380V current and power supply of L1, L2, L3 phase sequence at this time, and starting operating, water pump is into agitator
It supplies water, blender starts to stir；The normally opened contact of water pump main contactor KM1 is closed, time relay KT energized action, and is started
Timing, after reaching setting time, the delay normally-closed contact of time relay KT is disconnected, and water pump main contactor KM1 power-off is released
It puts, three main contacts of water pump main contactor simultaneously switch off, and pump motor M2 power loss shuts down, and water pump stops supplying water, or
Person operator is manually pressed by water pump stop button SB3 according to water supply situation, stops supplying water；It finishes, presses to concrete stirring
Stop button SB1, stirring main contactor KM power-off release are stirred, main contact simultaneously switches off, and stirring motor M1 stops stirring, so
Stirring change-over switch is switched into stop position afterwards；
Discharge the course of work:Stirring change-over switch is switched into unloading position, i.e. contact 3 and 4, contact 7 and 8, touching manually
Point 11 is connected with 12, and the output contact 4,8,12 for stirring change-over switch at this time is electronic according to the phase sequence arrangement and stirring of L3, L2, L1
The winding of machine is electrically connected, and is prepared for discharging starting；Stirring start button SB2 is then pressed, mixing control circuit is connected, stirring
The coil of main contactor KM obtains the voltage operation of 380V, makes the normally opened contact closure self-insurance for stirring main contactor KM, maintains to stir
Mix main contactor KM work, stirring main contactor KM main contact be closed at, at this time stir motor M1 winding obtain L3,
The three-phase 380V current and power supply of the phase sequence of L2, L1, reverse starting operating, while agitator reversely rotates discharging, when discharging terminates
Afterwards, stirring stop button SB1 is pressed, three main contacts of main contactor KM are stirred in stirring main contactor KM coil blackout release
It simultaneously switches off, stirring electric motor circuit breaking shuts down, and blender stops stirring, and stirring change-over switch is then switched to stop position
It sets, the contact for stirring change-over switch disconnects, and stirs motor stall, and blender stops discharging, completes a whipping process；
The either blender stirring course of work still discharges the course of work, as long as causing when overload accident occurs for blender
When overload of the current value higher than blender electrothermal relay FR1 in blender major loop adjusts threshold values, blender electrothermal relay FR1
Normally-closed contact disconnect, thus blender control circuit disconnect, the coil of blender main contactor KM is due to control loop power loss
Release, three main contacts of blender main contactor KM power off simultaneously, and stirring electric motor circuit breaking stops working, and can play protection
Stir the purpose of motor.
Beneficial effect compared with the existing technology is, using the above scheme, the utility model blender electrothermal relay FR1's
Output end is electrically connected by stirring change-over switch with the stirring motor M1 on the outside of control electric cabinet and the control of blender electricity
Road, when the overload that overload accident causes the current value in blender major loop to be higher than blender electrothermal relay FR1 occurs for blender
When adjusting threshold values, the normally-closed contact of blender electrothermal relay FR1 is disconnected, so that blender control circuit disconnects, stirring owner is connect
The coil of tentaculum KM is discharged because of control loop power loss, and three main contacts of blender main contactor KM power off simultaneously, stirring electricity
Motivation power-off stops working, to play the purpose of protection stirring motor；By the way that lifter is arranged under control electric cabinet, so as to
Height of the control electric cabinet apart from ground is adjusted according to on-site actual situations, the water inlet of control electric cabinet lower part is avoided, ensure that control electricity
The safety of cabinet.
It should be noted that above-mentioned each technical characteristic continues to be combined with each other, the various embodiments not being enumerated above are formed,
It is accordingly to be regarded as the range of the utility model specification record；Also, it for those of ordinary skills, can be according to above stating
It is bright to be improved or converted, and all these modifications and variations all should belong to the protection model of the appended claims for the utility model
It encloses.
