Description
Technical field
The utility model relates to mining equipment technical field, more specifically says that the on-the-spot liquid that returns of a kind of emulsification filters automatic back-flushing device.
Background technology
What colliery mostly adopted with hydraulic test is emulsion is as working media, and the cleannes of emulsion are directly connected to service behaviour and the service life thereof of hydraulic test; Foreign material that emulsion is taken out of in the time recycling in process through hydraulic test and cause coal dust that the factors such as working environment under particle and the coal mine coming off produce etc. all can pollute emulsion with inner-walls of duct through friction, make hydraulic test cisco unity malfunction or cause damage, therefore, emulsion is recycled to filtration in process very important, existing filter does not possess automatic back-flushing function, in the filter course of work, do not realize Hand scarf filter core and renew cartridge more online, can not meet the requirement that colliery serialization is produced.
Summary of the invention
For addressing the above problem, the utility model has designed one can realize automatic back-flushing function, in the course of work, can carry out Hand scarf filter core and renew cartridge more to device, the on-the-spot liquid that returns of emulsification that meets the continuous production requirement in colliery filters automatic back-flushing device, its technical scheme is: the on-the-spot liquid that returns of described emulsification filters automatic back-flushing device by high-pressure emulsion import, waste liquid recover, recover filter core, emulsion box, magnetic valve A, magnetic valve B, on-the-spot time liquid import, check valve, return liquid backwash filter, filter element, differential pressure check valve composition, the inlet that it is characterized in that back liquid backwash filter uses pipeline to return liquid import with scene respectively, the inlet of waste liquid recover connects, return in liquid backwash filter and on-the-spot connecting pipe of returning liquid import and have check valve, return in the connecting pipe of liquid backwash filter and waste liquid recover and have differential pressure check valve, the liquid outlet of waste liquid recover is connected with emulsion box, return liquid backwash filter liquid outlet by pipeline respectively with high-pressure emulsion import, emulsion box connects, return in the connecting pipe of liquid backwash filter and high-pressure emulsion import magnetic valve A is set, return in the connecting pipe of liquid backwash filter and emulsion box magnetic valve B is set.
Waste liquid recover described in the utility model, is characterized in that waste liquid recover inside arranges recover filter core, and waste liquid recover and recover filter core are detachable, convenient cleaning and replacing recover filter core.
Described in the utility model time liquid backwash filter, is characterized in that back that liquid backwash filter inside arranges filter element, and returning liquid backwash filter and filter element is monolithic construction.
Filter process: magnetic valve A closes, magnetic valve B opens, the scene that needs to filter is returned liquid and is returned liquid import by scene and enter back liquid backwash filter and filter through check valve, and the contaminant filter that scene is returned in liquid falls, then enters emulsion box through the magnetic valve B of unlatching.
Backwash process: magnetic valve A opens, magnetic valve B closes, high-pressure emulsion enters back liquid backwash filter through magnetic valve A, carry out backwash to returning liquid backwash filter, because emulsion is with high pressure, so pressure reduction check valve both sides produce pressure differential, in the time that pressure differential reaches 0.3KPA, the conducting of differential pressure check valve, emulsion enters waste liquid recover, then enters emulsion box.
The beneficial effects of the utility model are that the on-the-spot liquid filtration automatic back-flushing device that returns of emulsification is provided with back liquid backwash filter, can realize automatic back-flushing function, in the course of work, can realize Hand scarf filter core and renew cartridge more, meet the continuous production requirement in colliery.
