Description
Technical field
The utility model is related to emulsion box.
Background technology
Emulsion box is primarily used to supplement and stores the use liquid of working surface hydraulic support, when emulsion pump is extracted out in liquid case
Emulsion after by working face requirement output to hydraulic support realize that face roof supporting and stent push away for its action with this
It moves and advances, liquid will be back to emulsion box again after acting.Emulsion box be one provide emulsion source and liquid recycling it is normal
Pressure vessel.A hydraulic circulation system of emulsion box → emulsion pump → filter station → hydraulic support → emulsion box is formed from face
System.
Filter station is used to be filtered emulsion, but after the filter in filter station works long hours, it may occur that it is stifled
Plug, pressure drop increase, needs to be replaced frequently filter therefore.
Utility model content
The utility model aim, which is to provide one kind, to backwash filter, avoid replacing filter repeatedly, drop
The automatic backwash emulsion box of low use cost.
Automatic backwash emulsion box described in the utility model is emulsified including emulsion box, into liquid filter, for handle
Emulsion in liquid case is to the emulsion pump pumped into liquid filter；Emulsion pump outlet by be in series with liquid inlet electromagnetic valve into
Liquid branch is communicated with the import into liquid filter, also by be in series with the backwash branch of backwashing solenoid valve with into liquid filter
Outlet communicate；Inlet and outlet into liquid filter sets the inlet hydraulic of pressure at detection feed liquor filter inlet respectively
The fluid pressure meter of pressure at meter, detection feed liquor filter outlet；Into liquid filter import also with valvular blowdown of connecting
Branch communicates.
The beneficial effects of the utility model：During normal work, liquid inlet electromagnetic valve is opened, the conducting of feed liquor branch, backwash electricity
Magnet valve is closed, and backwash branch is obstructed.Emulsion pump extracts the emulsion in emulsion box out, by where liquid inlet electromagnetic valve
The import pumping of feed liquor Zhi Luxiang feed liquor filters, pumps out after the filtering into liquid filter from the outlet into liquid filter.
If feed liquor filter failure, liquid inlet electromagnetic valve is closed, and feed liquor branch is obstructed, and backwashing solenoid valve is opened, backwash branch conducting,
Meanwhile the valve of blowdown branch road is opened.Emulsion pump extracts the emulsion in emulsion box out, passes through backwashing solenoid valve institute
Backwash Zhi Luxiang feed liquor filters outlet pumping, emulsion passed through back through into after liquid filter into liquid filter
Outlet, the discharge of blowdown branch, to being backwashed into liquid filter, realize the regeneration into liquid filter.
There is impurity to enter into liquid filter when backwashing in order to prevent, above-mentioned automatic backwash emulsion box is recoiling
It washes branch road and is in series with pair into liquid filter.Preferably, it is provided on a bearing into liquid filter, liquid inlet electromagnetic valve, backwash
Solenoid valve is provided with feed liquor branch, backwash branch in bearing；Pair is removably disposed in into liquid filter in bearing.So
Pair can easily be replaced into liquid filter.
Above-mentioned automatic backwash emulsion box, it further includes controller, and inlet hydraulic meter, the output of fluid pressure meter are equal
Controller is connect, the output of controller taps into liquid electromagnetic valve, backwashing solenoid valve respectively；At feed liquor filter inlet pressure-into
During liquid filter outlet pressure ＜ 0.1MPa, controller control liquid inlet electromagnetic valve is opened, backwashing solenoid valve is closed；Work as feed liquor
At filter inlet at pressure-feed liquor filter outlet during pressure >=0.1MPa, controller control liquid inlet electromagnetic valve is closed, recoil
Wash solenoid valve opening.By the way that controller is set to monitor the pressure difference into liquid filter automatically, and according to differential pressure conditions to control
The break-make of liquid inlet electromagnetic valve processed and backwashing solenoid valve is realized and backwashed automatically.
