Abstract
The utility model provides an automatic reverse-flushing filter, which belongs to sewage purification equipment and structurally comprises a filter. A water inlet valve, a water outlet valve, a reverse-flushing water inlet valve and a reverse-flushing drain valve are respectively connected onto the filter, water pumping motors are connected onto the water inlet valve and the reverse-flushing water inlet valve respectively, a sensor and a turbidity meter are arranged at the position of the water outlet valve and connected with a PLC (programmable logic controller), and the PLC is used for acquiring information through the sensor and further connectedly controlling opening and closing of the water inlet valve, the water outlet valve, the reverse-flushing water inlet valve, the reverse-flushing drain valve and the water pumping motors. Compared with the prior art, the automatic reverse-flushing filter has the advantages of reasonable design, simple structure and the like, reverse-flushing cycle is unfixed, reverse flushing is performed along with change of water quality, and effluent quality is ensured to reach the standard so that sewage treatment is more efficient and intelligent.
Description
Technical field
The utility model relates to a kind of sewage purification treatment facility, a kind of specifically simple in structure, automatic backwashing filter.
Background technology
In sewage disposal process; Water gets into filter by inlet, along with the carrying out of filtering, because filter material surface and filter screen build up foul, impurity in the water; The upper surface that stops up filter screen will influence filter effect and effluent quality; Will carry out backwash this moment to recover the disposal ability of filter, traditional backwash process is generally regular manually-operated, and the cycle was generally about ten days.This backwash process can not in time reflect effluent quality, can't in time carry out backwash.
Summary of the invention
The technical assignment of the utility model is the deficiency that solves prior art, and a kind of simple in structure, automatic backwashing filter is provided.
The technical scheme of the utility model realizes by following mode; This automatic backwashing filter; Its structure comprises filter, is connected with water intaking valve, outlet valve, backwash water intaking valve, backwash draining valve on the said filter respectively, all is connected with pumping motor at water intaking valve, backwash water intaking valve place; Above-mentioned outlet valve place is provided with a sensor, transmissometer; This sensor, transmissometer are connected with programmable logic controller (PLC) PLC, and programmable logic controller (PLC) PLC carries out information gathering through sensor, and said programmable logic controller (PLC) PLC also connects the switching of control water intaking valve, outlet valve, backwash water intaking valve, backwash draining valve and pumping motor.
Described sensor, transmissometer are placed in the baffle-box.
Above-mentioned baffle-box is stainless fully sheathed case.
The current signal that said transmissometer produces the 4-20 milliampere gets into programmable logic controller (PLC) PLC.
Described sensor is a turbidity transducer.
The beneficial effect that the utility model is compared with prior art produced is:
Characteristics such as that the automatic backwashing filter of the utility model has is simple in structure, easy to use, be skillfully constructed, its structure adopts the PLC Based Intelligent Control, reduces operating personnel, makes things convenient for operational management, improves backwash efficiency; Backwashing period is unfixing, carries out backwash with change of water quality, guarantees that effluent characteristics is up to standard; And can reach corresponding emission request, thereby make sewage disposal more efficient, intelligent according to the threshold values of different discharge standard adjustment transmissometers.

The specific embodiment
Below in conjunction with accompanying drawing the automatic backwashing filter of the utility model is done following the detailed description.
Like accompanying drawing 1, shown in Figure 2, this automatic backwashing filter, its structure comprises filter 5; Be connected with water intaking valve 4, outlet valve 7, backwash water intaking valve 3, backwash draining valve 6 on the said filter 5 respectively; All be connected with pumping motor 2 at water intaking valve 4, backwash water intaking valve 3 places, wherein water intaking valve 4 is communicated with cesspool 1 through pumping motor 2, and sewage is evacuated in the filter 5; 7 of outlet valves are used to discharge the clear water through filtering; The clear water that outlet valve 7 is discharged is discharged in the clear water reserviors 12, and above-mentioned outlet valve 7 places are provided with a sensor 9, transmissometer 8, and said sensor 9, transmissometer 8 are placed in the baffle-box 10; Baffle-box 10 is a stainless fully sheathed case; This sensor 9, transmissometer 8 are connected with programmable logic controller (PLC) PLC11, and wherein transmissometer 8 produces the current signal entering programmable logic controller (PLC) PLC11 of 4-20 milliampere, and programmable logic controller (PLC) PLC11 carries out information gathering through sensor 9; Said programmable logic controller (PLC) PLC11 also connects the switching of control water intaking valve 4, outlet valve 7, backwash water intaking valve 3, backwash draining valve 6 and pumping motor 2, and described sensor 9 is a turbidity transducer.
The automatic backwashing filter of the utility model is when work; At first on programmable logic controller (PLC) PLC11, set turbidity value and carry out signals collecting through sensor 9, the current signal that produces through transmissometer 8 then gets into programmable logic controller (PLC) PLC11, carries out data and setting value and compares; When turbidity reaches setting value; Programmable logic controller (PLC) PLC11 pumping motor 2 carries out sequential control with valve, carries out backwash automatically, when turbidity during less than setting value; Once more motor and valve are carried out sequential control through programmable logic controller (PLC) PLC11, carry out further work.
Above-mentioned automatic backwashing filter can in time reflect effluent quality, and in time carries out backwash, makes sewage disposal more efficient, intelligent, thereby has good value for applications.
