Description

Full automatic back-flushing filter
A kind of various cooling systems, full-automatic backpulsing filter of lubricating system and various medium (as fluids such as air, water, emulsions) of being used for.
At present China's factories and miness are used in cooling, the filter of system such as lubricate, general by air bleeding valve, bring into, the upper and lower casing of outlet(discharge) flange, filter core, separator, frame etc. partly form, upper and lower casing and separator are assembled into a closed container, separator is located at the middle part of container, and the cavity volume of container is divided into epicoele and cavity of resorption.Have the duct on the separator, the cross section is fixedly mounted on the hole of separator at the filter core that is entwined on the metallic framework for circular metal filtration silk.Air bleeding valve is contained in upper shell top, and frame is contained in the lower house bottom.Filter is connected by upper and lower casing import and export flange and cooling, the pipeline that system such as lubricates by rack support on the ground simultaneously.Cooling, medium such as lubricated (as air, water, emulsion etc., down with) enter the filter cavity of resorption by the lower house suction flange, and the epicoele through inflow filter behind the filter element filtering on the separator hole is flowed out by the upper shell outlet(discharge) flange again.Because this filter is one-way flow; be that medium flows by a direction; therefore when filter core is blocked; must shut down the filter core taking-up is cleaned up reuse again; and artificial the cleaning is difficult to guarantee cleaning quality, so the reclamation rate of filter core is very low, the consumption of filter core is just very high like this; shut down simultaneously to cause to produce and interrupt, directly have influence on production efficiency.
The purpose of this utility model is to provide a kind of full-automatic backpulsing filter; can form a back flush runner in the cavity volume of this filter; when certain filter core is blocked; can lean on this back flush runner; the impurity that gets lodged in the filter core slit is washed out; simultaneously do not influence other not blocked filter core and carry out forward filter, whole system need not be shut down, thereby can guarantee carrying out continuously of production.
This full-automatic backpulsing filter that the utility model relates to is to improve and install additional blowdown breeches pipe, valve disc, Blowoff ball valve, sewage draining exit flange, driver, gear-box, control cabinet etc. partly to form on the basis of existing filter.The metal filtration silk of coiling filter core, its cross section are triangle.The blowdown breeches pipe is contained in the below of separator.Valve disc is equipped with in the upper end of blowdown breeches pipe, and valve disc is close to the lower plane of separator by spring, and forms clearance seal with separator.Blowoff ball valve and sewage draining exit flange are equipped with in the lower end of blowdown breeches pipe, and row's method ball valve and the sewage draining exit flange that is enclosed within on the Blowoff ball valve are fixed on the frame.The person in charge of blowdown breeches pipe is installed on the bearing position of separator and lower house, and the gear on the person in charge is connected with gears engaged on the driver.Driver, gear-box, control cabinet are contained on the frame, PC controller and pressure reduction are housed in the control cabinet show meter, and driver is connected on the main shaft of gear-box, and the electric switch on the driver is connected with the PC controller of control cabinet.Whole full-automatic backpulsing filter is connected on cooling, lubricates etc. on the pipeline of system by import and export flange and sewage draining exit flange.When filtering, cooling, medium such as lubricated enter the cavity of resorption of filter by the lower house suction flange, through becoming the epicoele of the medium inflow filter of cleaning behind the filter core forward filter on the separator, are flowed out by the upper shell outlet(discharge) flange again.When certain filter core was blocked, its pressure differential into and out of head piece increased, and the pressure reduction in the control cabinet shows that meter sends signal, under the automatic control of PC controller, and the automatic breakdown of the electric switch on the driver, gear-box and driver start thereupon.Under the drive of gear-box and driver, the person in charge of blowdown breeches pipe is rotated around the bearing position of separator and lower house, and valve disc then is attached on the lower plane of separator and rotates.When valve disc forwards that duct on the filter core place separator that is blocked to, just be parked in this position automatically, Blowoff ball valve is opened automatically simultaneously, blowdown this moment breeches pipe communicates with the filter core that is blocked, pressure reduction between the atmospheric pressure in the pressure of filter epicoele medium and the blowdown breeches pipe, cause forming in the filter one by the filter core of epicoele on separator, valve disc, the blowdown breeches pipe, Blowoff ball valve is until the reverse runner of sewage draining exit flange, filter epicoele cleaning medium relies on this reverse runner just, pressure according to itself recoils in filter core, the impurity of filter core inner surface is washed out, discharge by the sewage draining exit flange.When this filter core by backpulsing, other filter core is still carrying out forward filter, thereby filter does not quit work.Move in circles like this, the filter core on the separator is recoiled one by one, and the work of filter is also carried out continuously.Because being the metal filtration filament winding system of triangular-section, filter core forms, when medium is flowed through slit between the filter silk by cavity of resorption by the filter core forward filter, because of the slit is to expand from inside to outside, so process that medium therebetween has a bigger speed to fall, impurity greater than the slit is left in the filter core, can be uneasily outwards do not impact so that be stuck between the slit, thereby reduced possibility of jamming with medium.When in case the blocked needs of certain filter core clean, cleaning medium is by epicoele flow through the slit between the filter silk of filter core of recoiling, because of the slit is little in outer big, so impact process that medium therebetween has a speed sharply to rise again, this just feasible impurity that is attached to the filter core inner surface, quilt cleaning medium recoil is at a high speed discharged, thereby has improved the cleaning performance of filter core greatly.
The related this full-automatic backpulsing filter of the utility model is compared with existing filter, both saved to changing the time that the filter core that stops up allows filter stop work and to do, alleviated the work that the workman spends for the filter core of changing obstruction again, improved the use operating efficiency of separate unit filter greatly, the consumption of filter core simultaneously also than original minimizing half.
Below in conjunction with drawings and Examples structure of the present utility model is further elaborated.
