Abstract

The control device of the automatic Inlet and outlet water of a kind of raw water box, relate to the control device of the automatic Inlet and outlet water of raw water box in garbage power plant Water Treatment, belong to automation field, comprise raw water box and go out water pump, connect inlet channel on the top of described raw water box, inlet channel connects water inlet motor operated valve; Connect outlet conduit in the bottom of described raw water box, outlet conduit connect water outlet motor operated valve, described in go out water pump and be connected on outlet conduit, water outlet motor operated valve is arranged between the delivery port of raw water box and the water inlet going out water pump; Also connect blow-off line in the bottom of described raw water box, Bonding pressure formula fluid level transmitter and blowoff valve on blow-off line, pressure type liquid level transmitter is arranged between the sewage draining exit of raw water box and blowoff valve.This control device can avoid the water in raw water box to overflow, and brings inconvenience; The empty pump operation of water pump can also be avoided out, affect the life-span of pump; The workload of operating personnel can also be alleviated, save the plenty of time.

Description

The control device of the automatic Inlet and outlet water of a kind of raw water box
Technical field
The utility model relates to the control device of the automatic Inlet and outlet water of raw water box in garbage power plant Water Treatment, belongs to automation field.
Background technology
In garbage power plant Water Treatment, the operation of system needs to provide former water endlessly, and the water inlet of former water is faster than water outlet, and the time has been grown water and can overflow, and needs closing water inlet valve.Former water water inlet is slower than water outlet, and the time has been grown, and water tank can be empty, needs to close out water pump.Due to Water in Water Tanks number uncertain, so need operating personnel to monitor at any time, considerably increase the workload of site operation personnel like this, also can forget sometimes and closing water inlet valve and go out water pump water be overflowed, or empty pump operation, thus affect the life-span of pump.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides the control device of the automatic Inlet and outlet water of a kind of raw water box, alleviates labor strength, extends the application life water pump.
The purpose of this utility model is achieved in that the control device of the automatic Inlet and outlet water of a kind of raw water box, comprises raw water box and goes out water pump, connects inlet channel on the top of described raw water box, inlet channel connects water inlet motor operated valve; Connect outlet conduit in the bottom of described raw water box, outlet conduit connect water outlet motor operated valve, described in go out water pump and be connected on outlet conduit, water outlet motor operated valve is arranged between the delivery port of raw water box and the water inlet going out water pump; Also connect blow-off line in the bottom of described raw water box, Bonding pressure formula fluid level transmitter and blowoff valve on blow-off line, pressure type liquid level transmitter is arranged between the sewage draining exit of raw water box and blowoff valve.
The utility model will intake motor operated valve by inlet channel connection raw water box top, control the water inlet of raw water box.By water outlet motor operated valve with go out water pump and installed bottom raw water box by outlet conduit, water outlet motor operated valve is arranged on out before water pump, controls raw water box water outlet.Blowoff valve is arranged on water tank bottom by blow-off line, and blow-off line leads to blowdown ditch, is arranged on blow-off line by pressure type liquid level transmitter, according to the liquid level of the pressure measxurement raw water box water of Water in Water Tank.Water inlet motor operated valve control signal, water outlet motor operated valve control signal, water outlet pump control signal and pressure type liquid level transducer signal all transmit into PLC, in PLC, raw water box liquid level is compared, by PLC control to intake motor operated valve and water outlet motor operated valve, go out the switch of water pump.This raw water box height 4m, when raw water box liquid level is greater than 3.8m, PLC puts water motor operated valve automatically into, stops water inlet; When raw water box liquid level is less than 0.2m, PLC drives water motor operated valve automatically into, starts water inlet.When raw water box liquid level is less than 0.5m, PLC automatically first closes out water pump and closes water outlet motor operated valve again, stops water outlet; When raw water box liquid level is greater than 3.5m, PLC automatically first outputs water motor operated valve and outputs water pump again, starts water outlet.
This control device can avoid the water in raw water box to overflow, and brings inconvenience; The empty pump operation of water pump can also be avoided out, affect the life-span of pump; The workload of operating personnel can also be alleviated, save the plenty of time.This control device novel structure, reasonable in design, reliable operation, with low cost, be suitable for and apply.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, the control device of the automatic Inlet and outlet water of raw water box, comprises raw water box 2, connects inlet channel 5 on the top of raw water box 2, inlet channel 5 connects water inlet motor operated valve 1, controls the water inlet of raw water box 2.Connect outlet conduit 10 in the bottom of raw water box 2, outlet conduit 10 connects water outlet motor operated valve 7 and goes out water pump 4, water outlet motor operated valve 7 is arranged between the delivery port of raw water box 2 and the water inlet going out water pump 4.Blow-off line 11 is also connected in the bottom of raw water box 2, Bonding pressure formula fluid level transmitter 3 and blowoff valve 8 on blow-off line 11, pressure type liquid level transmitter 3 is arranged between the sewage draining exit of raw water box 2 and blowoff valve 8, and the other end of blow-off line 11 leads to blowdown ditch 9.
Water inlet motor operated valve 1 control signal, water outlet electric valve control 7 signal processed, go out water pump 4 control signal and pressure type liquid level transmitter 3 signal all transmits into PLC control system 6, in PLC control system 6, raw water box 2 liquid level is compared, by PLC control system 6 control to intake motor operated valve 1 and water outlet motor operated valve 7, go out the switch of water pump 4.
This raw water box height 4m, when raw water box liquid level is greater than 3.8m, PLC puts water motor operated valve automatically into, stops water inlet; When raw water box liquid level is less than 0.2m, PLC drives water motor operated valve automatically into, starts water inlet.When raw water box liquid level is less than 0.5m, PLC automatically first closes out water pump and closes water outlet motor operated valve again, stops water outlet; When raw water box liquid level is greater than 3.5m, PLC automatically first outputs water motor operated valve and outputs water pump again, starts water outlet.
