Abstract
The utility model relates to an automatic running control system of a primary settling segment sludge pump for a sewage treatment plant. The primary settling segment sludge pump comprises a plurality of substation sludge pumps. The control system comprises an upper computer and a plurality of substation PLCs (programmable logical controllers), wherein the substation PLCs are connected with the substation sludge pumps; the upper computer is respectively connected with the plurality of substation PLCs in a communicating way; the control system further comprises a master station PLC connected with the upper computer in a communicating way, and the master station PLC is respectively connected with the plurality of substation PLCs. The automatic running control system utilizes the master substation PLC communicated with the upper computer to control all the substation PLCs used for respectively controlling the plurality of substation sludge pumps in a centralized way, so as to make sure that the substation sludge pumps can still run automatically even if the upper computer and the substation PLCs generate communication faults, thereby thoroughly liberating hands of operating personnel and realizing the automation of industrial control.
Description
Technical field
The utility model relates to a kind of first heavy section automatic operation control system of sludge pump that is used for sewage treatment works.
Background technique
At present, increasing sewage treatment works begins to adopt advanced biotechnology sewage disposal system to realize the purification process of water quality; The working procedure of this sewage disposal system is generally: at first, raw sewage by the thickness grid enters setting pot afterwards through grid or sieve rate device, sewage through the sand water separation enters primary sedimentation pond (hereinafter to be referred as initial precipitating tank), more than handles (being physical treatment) for one-level; Then, the water outlet of initial precipitating tank enters secondary sedimentation tank (hereinafter to be referred as initial precipitating tank) through biological treating equipment, and the water outlet of secondary precipitating tank is through the sterilization discharging or enter tertiary treatment, and the one-level processing finishes to be secondary treatment to this; Tertiary treatment can comprise the biological carbon and phosphorous removal method, coagulant sedimentation, sand filtration method, active carbon adsorption, zeolite process and electroosmose process etc.In addition, the mud part of secondary precipitating tank is back to initial precipitating tank or biological treating equipment, and a part enters sludge concentration tank, enters sludge digestion tank afterwards, and behind dehydration and drying equipment, mud is utilized at last.
In above-mentioned sewage disposal process, initial precipitating tank is one of method of the most frequently used and the simplest processing organic solid thing, and solid matter and constantly is discharged under the effect of some sludge pumps as primary sludge in initial precipitating tank at the bottom of the constantly heavy people pond.Yet, this sludge pump of heavy section just mostly is operation manually or at present by upper-position unit centralized control, processing, and then under unit start and stop pattern, control the start and stop of each sludge pump automatically by each substation PLC, this control mode can not normally be moved the automatic start-stop pattern of sludge pump when the communication between upper-position unit and the substation PLC is broken down.Therefore, In view of the foregoing, the automatic operation control system that presses for now this sludge pump improves.
The model utility content
In order to solve the problem that above-mentioned prior art exists, the utility model aims to provide a kind of first heavy section automatic operation control system of sludge pump that is used for sewage treatment works, to realize the purpose of just heavy each sludge pump of section of regularly start and stop on schedule.
A kind of first heavy section automatic operation control system of sludge pump that is used for sewage treatment works described in the utility model, described just heavy section sludge pump comprises several substation sludge pumps, described control system comprises a upper-position unit and several substation PLC that is connected with described substation sludge pump respectively, and described upper-position unit is connected with the PLC communication of described several substations respectively, described control system also comprises a PLC of main website that is connected with described upper machine communication, and the PLC of this main website is connected with described several substations PLC respectively.
Owing to adopted above-mentioned technical solution, the utility model is by adopting by all control the mode of the substation PLC of each substation sludge pump respectively with the PLC of the main website centralized control of upper machine communication, substitute traditional by upper-position unit centralized control, processing, automatically control the control mode of sludge pump again by each substation PLC, even to guarantee when communication failure appears in upper-position unit and substation PLC, the substation sludge pump still can move automatically, thereby thoroughly allow operator liberate both hands, realize industrial control automation.
Description of drawings
Fig. 1 is a kind of structural representation that is used for the first heavy section automatic operation control system of sludge pump of sewage treatment works of the utility model.
Embodiment
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
As shown in Figure 1, just heavy section sludge pump comprises several substation sludge pumps 10.The utility model, be a kind of first heavy section automatic operation control system of sludge pump that is used for sewage treatment works, comprise a upper-position unit 1, a PLC2 of main website that is connected with upper-position unit 1 communication and several substation PLC3 that is connected with the PLC2 of main website respectively, wherein, several substations PLC3 connects one to one with several substation sludge pumps 10 respectively on the one hand, is connected with upper-position unit 10 communications respectively on the other hand.
In the utility model, upper-position unit 1 is used for depositing basic parameter in main website PLC2, basic parameter comprise automatic operation starting time, each substation sludge pump 10 working time, start blanking time, high alarm setting value etc., and have corresponding button that each time point is activated and cancel activation, state of activation also leaves in the PLC2 of main website by upper-position unit 1; The PLC2 of main website is used for starting automatically according to the point of setting starting time, and one by one the start and stop instruction is distributed to different substation PLC3 by the fixed time interval of setting; The enabled instruction that each substation PLC3 sends according to the PLC2 of main website on the one hand, begin from high to low to judge that according to priority can the sludge pumps at different levels in the substation sludge pump 10 normally start, if can normally start and then start this grade sludge pump, otherwise jump to the sludge pump of next priority, what the wait PLC2 of main website sent when sludge pumps at different levels all can not start ceases and desist order automatically; On the other hand, each substation PLC3 can feed back to substation sludge pump 10 current automatic runnabilitys upper-position unit 1 demonstration.
Upper-position unit 1 in the utility model adopts the AS-PE2900 server of DELL; The PLC2 of main website adopts 5000 series of PLC of ROCKWELL; Substation PLC3 adopts 5000 series of PLC of ROCKWELL.
Below embodiment has been described in detail the utility model in conjunction with the accompanying drawings, and those skilled in the art can make the many variations example to the utility model according to the above description.Thereby some details among the embodiment should not constitute qualification of the present utility model, and the scope that the utility model will define with appended claims is as protection domain of the present utility model.
