Accompanying drawing explanation
Figure 1 shows that the structural representation of the Controlling System of back yard industry wastewater treatment equipment of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
As shown in Figure 1, the Controlling System of back yard industry wastewater treatment equipment of the present invention comprises PLC unit, the touch-screen type display screen be connected with described PLC unit communication, be provided with in the water tank of described back yard industry wastewater treatment equipment with described PLC unit communication link there is the liquid level sensor that hi-lo signal alarm exports, the impeller pump of described back yard industry wastewater treatment equipment, the mixing pump of whipping appts and the aeration pump of aerating apparatus are connected with described PLC unit is controlled respectively, also comprise be arranged on back yard industry wastewater treatment equipment pH regulator pond in and with described PLC unit communication link pH detecting unit, the dosing pump of the chemicals dosing plant of described back yard industry wastewater treatment equipment is connected with described PLC is controlled.
Specifically, the present invention is processed back yard industry waste water by PLC, adopt the running condition representing each step in whole system of touch-screen, each assembly and PLC unit are by One-position switch amount transmission information, control and the situation of each link of feedback so that correct electrical action can be made, to ensure the normal operation of system.
The present invention gathers two position in each water tank by PLC unit, defines the liquid level that each water tank should reach interval, and automatically and PLC unit be associated, and the start and stop of automatic shutter impeller pump, accomplish constant level.Chemicals dosing plant and aerating apparatus and whipping appts are controlled associating simultaneously, can superposition effectively on practical function and addition, there is good reactivity to water quality.
Specifically, the Controlling System of back yard industry wastewater treatment equipment of the present invention has following characteristics.
1. the present invention realizes centralized Control by PLC unit, solve and existingly can not get information about the running status of equipment about control system equipment in sewage disposal technology exists, the relative less stable of Controlling System, failure rate is high, and needing after fault can practical function action problem to intermediate relay and rly. hardwire.
2. small-sized sewage treating system PLC unit electric controller, by the process flow sheet on touch-screen, the operation conditions of equipment is very clear, and the moment can recognize the function situation of any element, according to setting pH value, regulating in each procedure from motion tracking should the situation of dosing, and equipment realizes running automatization.And will automatically start mixing pump and aeration pump when dosing or soda acid are in harmonious proportion, there is good reactivity to water quality.
3. gather two position in a water tank by PLC unit; define the liquid level interval that each water tank should reach; and automatically and PLC unit be associated; and the start and stop of automatic shutter impeller pump; accomplish constant level, occur abnormal also auto stop, prevent the anhydrous sky of water pump from taking out and damage equipment; when after water, automatically open.And having corresponding fault alarm, the failure message of touch-screen display simultaneously, when wherein certain pump has fault, excises the interruption of work of this pump automatically, and has corresponding warning instruction and failure message to show on the touchscreen.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
