Abstract
The utility model discloses an auto drainage controller for silo, water sink, water tank, etc,. the water level of which need to be controlled. The utility model comprises a stabilized voltage power supply, a comparator, an amplifier, an overbound water level alarm and a sensor electrode, and is an auto drainage controller with stable operation performance and convenient maintenance.
Description
Technical field:
The utility model relates to the plumbing field, relates in particular to melt pit robotization draining.
Background technology:
In industrial and mining enterprises, some equipment is in the position of below ground, for preventing that equipment from being seeped water or rainwater floods, adopts water pump to carry out draining usually.Control is implemented in the melt pit draining at present main data that adopt ball float to gather water level of control automatically.Because ball float is installed inconvenience, 220 volts voltage is linked on the mercury contact in the ball float by cable in addition, cable for a long time in water immersion insulation is descended cause short circuit, both dangerous, maintenance is inconvenience extremely also.
Summary of the invention:
The purpose of this utility model is to provide a kind of stable work in work, easy to maintenance, safe and reliable automatic water discharge controller.
In order to achieve the above object, the technical solution of the utility model is: a kind of automatic water discharge controller is characterized in that: it is made up of stabilized voltage supply, comparer, amplifier, overload alarm device, electrode; By transformer TC1, diode D1～D4, the stabilized voltage supply that capacitor C 1, C2 and three terminal regulator 7809 are formed provides direct current to circuit, and the positive termination of stabilized voltage supply is in the electrode D of melt pit bottom; By amplifier ic chip 1, resistance R 1, R2, R3, R4 form comparer, and electrode A links to each other the normal opened contact of series relay KA1 between electrode B and the electrode A with input end " ten " end; Form amplifier by voltage stabilizing diode DW1, triode BG1, relay K A1 and diode D5; Form comparer as overload alarm device usefulness by amplifier ic chip 2 and resistance R 5, R6, R7, R8, electrode C is connected with input end " ten " end; By voltage stabilizing diode DW2, triode BG2, relay K A2 and diode D6 form amplifying circuit; The position of four electrodes is followed successively by from low to high: D, B, A, C.
Beneficial effect: easy to maintenance, safe and reliable, stable work in work.
Description of drawings:
Accompanying drawing is a specific embodiment of the utility model.
Wherein: TC1-power transformer D-diode BG-triode R-resistance C-electric capacity KA-relay DW-stabilivolt Ico-three terminal regulator Ic1, Ic2-amplifier integrated package A, B, C, D-electrode 1, melt pit 2, water level.
Embodiment:
Shown in the accompanying drawing.By transformer TC1, diode D1～D4, the voltage stabilizer that capacitor C 1, C2 and three terminal regulator 7809 are formed provides 9 volts of direct supplys to circuit, power positive end receiving electrode D, its position is in the melt pit bottom; By amplifier integrated package Ic1, resistance R 1, R2, R3, R4 form comparer, and electrode A links to each other the normal opened contact of series relay KA1 between electrode B and the electrode A with input end "+" end; Form amplifying circuit by voltage stabilizing diode DW1, triode BG1, relay K A1 and diode D5; Form comparer as overload alarm usefulness by amplifier integrated package Ic2 and resistance R 5, R6, R7, R8, electrode C is connected with input end "+" end; By voltage stabilizing diode DW2, triode BG2, relay K A2 and diode D6 form amplifying circuit.The entire work process branch carried out as the next stage:
1, when electrode B (low-water level) is run in 2 risings of the water level in the melt pit 1, the draining air pump inoperative.
2, when electrode A (high water stage) is run in water level 2 risings, input end "+" terminal potential of its amplifier integrated package is higher than "-" terminal potential, output terminal is by " 0 " change " 1 " triode BG1 conducting, relay K A1 adhesive, and the contactor that its contact drives main control loop starts unwatering pump.
3, after unwatering pump started, water level 2 began to descend, when being lower than electrode A, because of relay K A1 junction closure electrode B is communicated with the electrode A circuit, so unwatering pump remains in operation.
4, when water level was reduced to electrode B 2 times, the output of amplifier integrated package then became " 0 " by " 1 ", and relay K A1 discharges, and unwatering pump shuts down.
5, break down can not draining the time when unwatering pump, water level 2 rises and meets electrode C, then relay K A2 adhesive, and its contact drives alarm and sends fault-signal.
