Abstract
The utility model relates to a backwashing filter device for a liquid return system, comprising filter cylinders, backwashing filter cores, a backwashing valve, an electromagnetic valve and a safety valve, wherein the liquid return pipe of an external bracket system of the device is connected with a liquid inlet interface at one side of a shell of the device; the other side of the shell is provided with a filter liquid outlet; the lower part of the shell of the device is provided with two filter cylinders which are internally and respectively provided with one backwashing filter core; the backwashing valve is arranged above the shell; the electromagnetic valve is arranged in the shell between the filter liquid outlet and the liquid inlet interface; and the safety valve is arranged in the shell positioned at one side of the liquid inlet interface. The backwashing filter device has the benefits that emulsified liquid for the bracket under a coal mine needs to be filtered in the use process, the backwashing can be carried out under the condition without stopping a machine, and the liquid return of the system can not be influenced; and in addition, when realizing backwashing, the backwashing filter device also plays a role in the filter core.
Description
Technical field
The utility model relates to a kind of filter, relates in particular to a kind of back-flushing filtering device that is used for return liquid system.
Background technology
Present emulsification pumping plant return liquid system is general to adopt fixed filter that liquid back pipe road system is filtered, system's liquid back pipe is because after having passed through a working cycles, various impurity are full of pipeline, its time of return liquid system liquid filter commonly used can only adopt the very low filter core excessively of precision, otherwise the cleaning and filtering core that results in blockage easily and need be frequent, increased mounting system after the obstruction to a certain extent and returned the back pressure of sap cavity, stent valve group bungle rate has been increased, thereby produce certain potential safety hazard.
The utility model content
At above defective, the purpose of this utility model provides a kind of back-flushing filtering device that is used for return liquid system, to be implemented under the non-stop-machine situation filter core is oppositely cleaned.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of back-flushing filtering device that is used for return liquid system, comprise cartridge filter, backwash filter core, backwash valve, magnetic valve, safety valve, the liquid back pipe of device outside support system is connected with the feed liquor interface of device case one side, the opposite side of housing is installed and is filtered liquid outlet, the device case bottom is provided with two cartridge filters, each cartridge filter inside is provided with a backwash filter core, and backwash valve is installed in the housing top; Enclosure interior is installed magnetic valve between described filtration liquid outlet and the feed liquor interface, and the enclosure interior that is positioned at feed liquor interface one side is installed safety valve, and described backwash valve one side is provided with hydraulic control one-way valve.
The beneficial effect that is used for the back-flushing filtering device of return liquid system described in the utility model is: when the coal mine lower carriage in use needs to filter with emulsion, can oppositely clean filter core under non-stop-machine situation, liquid returns in the system that can not influence; In addition, when realizing anti-the cleaning, also play the effect of protection filter core.
Description of drawings
According to embodiment and accompanying drawing the utility model is described in further detail below.
Fig. 1 is the described structural representation that is used for the back-flushing filtering device of return liquid system of the utility model embodiment;
Fig. 2 is the described side-looking partial schematic diagram that is used for the back-flushing filtering device of return liquid system of the utility model embodiment.
Among the figure:
1, cartridge filter; 2, backwash filter core; 3, filter core bearing; 4, plug; 5, backwash valve; 6, filter liquid outlet; 7, magnetic valve; 8, hydraulic control one-way valve; 9, safety valve; 10, feed liquor interface.
The specific embodiment
Shown in Fig. 1-2, the back-flushing filtering device that is used for return liquid system described in the utility model, comprise cartridge filter 1, backwash filter core 2, backwash valve 5, magnetic valve 7, safety valve 9, the liquid back pipe of device outside support system is connected with the feed liquor interface 10 of device case one side, the device case bottom is provided with two cartridge filters 1, each cartridge filter 1 inside is provided with a backwash filter core 2, and backwash filter core 2 tops are provided with filter core bearing 3, and backwash valve 5 is installed in the housing top; The opposite side of device case is installed and is filtered liquid outlet 6, enclosure interior is installed magnetic valve 7 between described filtration liquid outlet 6 and the feed liquor interface 10, the enclosure interior that is positioned at feed liquor interface 10 1 sides is installed safety valve 9, described backwash valve 5 one sides are provided with hydraulic control one-way valve 8, and outer end, case side facial canal road is provided with plug 4.During work, its inner two groups of filter elements are worked simultaneously, when regularly oppositely cleaning, one end of magnetic valve 7 gets, a hydraulic control backwash valve 5 wherein cuts out this valve, and the hydraulic coupling that the backwash valve 5 that this moment, filter core was opened by another is come in is from the inner outwards backwash of filter core, thereby rinses out the binding of filter core outside, reach the purpose of back flush, the booty of cleaning is got rid of by sewage draining exit; The other end of magnetic valve 7 gets the electric alternately cleaning that can realize two filter cylinders, thereby liquid returns in the system that can not influence, security protection after surge pressure that produces when safety valve 9 main releases are alternately cleaned or the filter core moment obstruction, by filtering liquid outlet 6 stream liquid-return box, realize the process of whole filtration through the liquid after filtering; Liquid back pipe road back pressure should not be higher than 2Mpa, and the back pressure spring opening pressure of safety valve 9 is 0.35Mpa, so this device also plays the effect of protection filter core when realizing anti-the cleaning.
