Description
Technical field
This utility model relates to filtration art, is specifically related to a kind of bag filter.
Background technology
Along with at present, bag filter common on the market, its operation principle is: liquid enters into and is flowed in filter bag in filter, and liquid is filtered by filter bag, and the granule foreign in liquid is left in filter bag.When sock filtration effect is poor, just take out filter bag to be replaced, when this common bag filter has the disadvantage that sock filtration, granule foreign is retained on the surface of filter bag, the surface of blocking filter bag, makes the rate of filtration of filter bag and filter efficiency reduce, reduces the filter efficiency of filter, it is accomplished by again changing filter bag when filter bag efficiency reduces, changing filter bag excessively frequent, add cost, practical application effect is poor.
Summary of the invention
The purpose of this utility model is to propose a kind of bag filter, to reduce the replacement frequency of filter bag.
A kind of bag filter described in the utility model, including the housing of upper end open with for closing the lid of the opening of described housing, described lid and described housing surround airtight cavity, it is provided with dividing plate in described housing, described cavity is separated into the first cavity and the second cavity by described dividing plate, described first cavity is between described lid and described dividing plate, and described second cavity is between the bottom of described dividing plate and described housing；The side of described housing is provided with water inlet pipe, and the lower end of described water inlet pipe is from top to bottom through the bottom of described housing, and the upper end of described water inlet pipe is through described dividing plate and connects with described first cavity；The opposite side of described housing is provided with outlet pipe, and the upper end of described outlet pipe is passed the bottom of described housing and connects with described second cavity, and the lower end of described outlet pipe is positioned at the outside of described housing；Described dividing plate is provided with through hole, and described through hole is provided with filter bag, and described filter bag includes the bag mouth coordinated with described through hole and the bag being positioned at described second cavity；Described housing is externally provided with water pump, and described water pump is connected to the first water pipe and the second water pipe, and one end of described first water pipe is connected with the water inlet of described water pump, and the other end of described first water pipe connects with described outlet pipe；One end of described second water pipe is connected with the outlet of described water pump, the other end of described second water pipe is connected to the sparge pipe being positioned at described second cavity, described sparge pipe is positioned at by described filter bag, and described sparge pipe is evenly distributed with the hole for water spraying towards described filter bag；Being provided with hydraulic pressure sensor in described first cavity, described hydraulic pressure sensor is connected by circuit with described water pump, and described hydraulic pressure sensor is for controlling the opening and closing of described water pump.
Adopt technique scheme, the hydraulic pressure in the first cavity is detected by hydraulic pressure sensor, when the granule foreign of filter bag inner surface is too much, affect the filter efficiency of filter bag and the hydraulic pressure in the first cavity can be made to raise, when the hydraulic pressure in the first cavity is higher than during to setting value, hydraulic pressure sensor sends signal to water pump, water pump is started working, water pump extracts water in outlet pipe and sprays through sparge pipe, the water impact filter bag of sparge pipe ejection, the granule foreign making filter bag inner surface departs from the inner surface of filter bag, make granule foreign will not block the inner surface of filter bag, thus improve the rate of filtration and the filter efficiency of filter bag, improve the filter efficiency of bag filter, the hydraulic pressure in the first cavity also can be made to reduce simultaneously；When the hydraulic pressure in the first cavity is lower than setting value, hydraulic pressure sensor sends signal to water pump, and water pump quits work.Above-mentioned setting value is artificial setting, and under the control of hydraulic pressure sensor, bag filter can run automatically, automatically clears up filter bag.
Further, described second water pipe being provided with check valve, described check valve flows to water pump for stoping the water in described second water pipe.
Further, described lid is installed on the housing by bolt.
This utility model is rational in infrastructure, easy to use, can automatically run, so that the granule foreign of filter bag inner surface departs from filter bag inner surface, thus improve the rate of filtration and the filter efficiency of filter bag, improve the filter efficiency of bag filter, decrease the frequency changing filter bag, reducing cost, result of use is good, is beneficial to popularization.
