However existing bag filter filter device disadvantage:It A. need to be by required fineness grade when conventional bag filter uses Filter bag be mounted in filter cylinder, check and screw filtering cartridge lid annular bolt after sealing ring is intact, you can devote oneself to work, but with using The extension of time, filter residue gradually increases in cylinder, and pressure rise after filter core is blocked by impurities in liquid need to shut down opening cover, into It can be continuing with after row filter bag replacement operation, can not accomplish continuous production, and filter element cleaning is difficult after replacement, there are waste liquids to overflow Stream, the problems such as cost is higher;B. conventional bag filter is in use, because filter volume is larger, head cover weight weight, a worker It is difficult to operate, it is mobile difficult, without external pressure system interface, need independent matching pump, piping connection complicated;Nothing improves protective device And measuring instrument, it can not accomplish that dynamic monitoring filtering situation, no pipeline cleaning and filter bag cleaning function, replacement operation take consumption Power.
Utility model content
Problem to be solved in the utility model is to provide a kind of automatic backwash bag type filter device, passes through dynamic monitoring Pressure in filter identifies filter bag stopping state, and then carries out automatic backwash to filter bag, is achieved that without carrying out filter bag dismounting On-line cleaning reduces cost to extend filter bag usage time.
To achieve the above object, the technical solution that the utility model is taken is as follows:A kind of automatic backwash bag type filtering dress It sets, including bag filter, pneumatic diaphragm pump, pressure sensor, controller, for liquid pool and waste liquid pool, bag filter has Filtration barrel body is sealingly mounted at the filtration barrel cover on filtration barrel body top, the filter bag being installed on inside filtration barrel body, cartridge filter side Wall top is equipped with feed inlet, and lower sidewall is equipped with discharge port and rinse mouth, and bottom is equipped with waste liquid port connection filter bag inner cavity, feed inlet Inlet tube is connect by the first solenoid valve and third battery valve respectively with rinse mouth, and pneumatic diaphragm pump, gas are connected by threeway The dynamic diaphragm pump other end is stretched by inlet tube for liquid pool, and discharge port connects outlet tube by second solenoid valve, and waste liquid port passes through 4th solenoid valve connects sewer pipe, and sewer pipe stretches into waste liquid pool, and pressure sensor is mounted on filtration barrel cover, in filter Portion's air pressure is monitored;And monitoring data are sent to the controller mounted on cylinder body outer wall, the first electromagnetism is controlled by controller The break-make of valve, second solenoid valve, third solenoid valve and the 4th solenoid valve.
Preferably, further including moving carriage, the bag filter, pneumatic diaphragm pump is fixed for liquid pool and waste liquid pool In moving carriage.
Preferably, first solenoid valve, second solenoid valve, third solenoid valve and the 4th solenoid valve are unidirectional electromagnetism Valve.
Preferably, having partition board inside the filtration barrel body, filter bag is installed on partition board, and inlet is located above partition board Filtration barrel body side wall, liquid outlet and rinse mouth are located at the filtration barrel body side wall below partition board.
Advantageous effect:A kind of revealed automatic backwash bag type filter device of the utility model has following beneficial to effect Fruit:
Filter device may be implemented according to use demand into line position in mobile base using moving carriage as filter device Convenient movement is set, the difficult problem of conventional filters movement is overcome;
In filter cylinder bottom, setting waste liquid port is connected to filter bag inner cavity, and the rinse mouth of side is coordinated to realize to the reversed of filter bag inner wall It rinses so that the impurity of filter bag inner wall flows into waste liquid pool;
Pressure sensor is set on bung, valve is set on each pipeline, by pressure sensor dynamic monitoring cylinder Pressure value, and the break-make of each valve is controlled with free switching filtering by controller and backwashes two states, without artificially sentencing It is disconnected whether to need to carry out filter element replacing, will not equally there be the case where waste liquid overflow;
Rinse mouth is connected by pneumatic diaphragm pump for liquid pool with inlet, is also to use filter medium carrying out backwash It carries out, not only simplifies filtration system structure, realize the continuous liquid supply of filtration condition and backwashing state;And it is situated between using filtering Matter carries out backwash and can fully be infiltrated to filter bag, will not influence filtering because clear water remains in continuous filtering and be situated between The viscosity characteristics of matter, and it is good to the dissolubility of impurity using filter medium, flushing effect is more preferably;
Regular backwash operation may be implemented in the present apparatus, and promote filter core uses duration and service life, thereby reduces The triviality manually cleaned, also reduces cost of labor, improves production efficiency.
