Embodiment
Air-strainer of the present utility model, comprise upper shell 5 and lower shell body 6, described upper shell 5 is the drum shape body of annular for the cross section, its top is equipped with a umbrella crown 2, outer tube side wall is provided with air outlet 21, and one-level filter screen 3, secondary filter core 9 and three grades of filter screens 8 are installed in the inner core of the ingress of above-mentioned umbrella crown 2, upper shell 5 and the urceolus successively.Above-mentioned secondary filter core 9 belows are provided with the gas and oil separating plant with oil-collecting function, and this gas and oil separating plant is to be by section
Oil filtering disc 10-1, the section of shape are
The air passing hole 10-2 of shape, oil-collecting baffle plate 10-3 and several fluid tubes 10-4 form, wherein oil-collecting baffle plate 10-3 is installed between the outer side wall of the inner tube wall of upper shell 5 and air passing hole 10-2, make oil-collecting baffle plate 10-3, upper shell 5 and air passing hole 10-2 constitute the oil-collecting space, fluid tube 10-4 is connected with oil filtering disc 10-1 and the fluid that is collected on the oil filtering disc 10-1 is imported the oil-collecting space, moving back 12 fluid with the oil-collecting space of oil pipe imports in the subsing tank 16 of lower shell body 6 bottoms, be provided with anti-reverse plate 11 in the described subsing tank 16, be used for preventing that the dust that precipitates from turning back to oil bath liquid once more, being used to make sludge to concentrate discharges, keep purer oily bathing oil, above-mentioned oil-collecting baffle plate 10-3 can tilt to moving back oil pipe 12 directions when design slightly, and the bottom of lower shell body 6 then tilts along subsing tank 16 directions.
Described lower shell body 6 bottoms are oil bath, it is by the outside set repairing kettle 1 of filter cleaner fluid to be injected into wherein, for balanced oil bath, the utility model is equipped with an automatic oil recharging device in the fluid ingress, and what this automatic oil recharging device adopted is oil float structure 20; Oil bath liquid in the lower shell body 6 is sent to the set spray bar 4 in upper shell 5 tops by the fluid feedway, to realize that cleaning secondary filter core and fluid adhere to the function of filter core once more, the oil outlet place that above-mentioned lower shell body 6 is communicated with the fluid feedway is provided with oil bath filter screen 13, and the fluid that is used to guarantee to send into spray bar 4 is pure relatively.
In order to concentrate dust discharge, on subsing tank 16, also be connected with dust exhaust, the utility model is selected dual mode for use: natural sedimentation dust discharge or dust discharge automatically, so-called natural sedimentation dust discharge is meant and allows the dust natural subsidence in natural sedimentation cup 23, manually dust outwelled; So-called automatic dust discharge is meant fluid feedway and dust discharge cylinder interlock automatically, the control dust discharge, this automatic dust discharge cylinder is made up of the dust discharge valve 19 of dust discharge cylinder body 17, dust discharge piston 18 and bottom, and above-mentioned dust discharge piston 18 is provided with several oil guide slot 24, and dust discharge valve 19 is provided with dust exhausting hole 25.
Be exactly to utilize fluid feedway and dust discharge cylinder interlock automatically below, realize the dual mode of automatic dust discharge:
One. selecting pneumatic cylinder for use is the fluid feedway, this pneumatic cylinder 14 bumps air valve with the electricity of time relay control and is connected, and itself and lower shell body 6, be respectively equipped with one-way valve 15 on the pipeline that spray bar 4 connects, the push rod of pneumatic cylinder 14 drives dust discharge piston 18 motions of automatic dust discharge cylinder, realize dust discharge and oil spout interlock: during energising, the piston that the electricity of time relay control bumps air valve drive pneumatic cylinder 14 moves down, because the single effect of one-way valve 15, oil bath liquid in the pneumatic cylinder 14 is sprayed on secondary filter core 9 by spray bar 4, simultaneously, the dust discharge piston 18 that the push rod of pneumatic cylinder 14 drives automatic dust discharge cylinder moves down, at this moment, when if dust concentration is big in the fluid, pressure impels dust to discharge along the exhaust port on the dust discharge pressure regulator valve 19 25, dust concentration hour, fluid then can flow to dust discharge cylinder body 17 tops along the oil guide slot on the dust discharge piston 18 24, does not carry out dust discharge work; After the outage, closes compression gas also bleeds off unnecessary pressurized gas, and pneumatic cylinder 14 pistons move under action of reset spring, and the single effect of one-way valve 15 is sucked in the pneumatic cylinder 14 the oil bath liquid in the lower shell body 6, finishes once circulation.
Two, select for use motor as the fluid feedway, it is logical with the oil bath liquid phase to be about to motor 7, and mounting teeth wheel pump thereon, retarder and eccentric wheel 22, dust discharge piston 18 motions with eccentric wheel 22 automatic dust discharge cylinders, to realize automatic dust discharge purpose: during energising, the motor 7 driven gear pumps of time relay control, eccentric wheel 22 motions, gear pump is driven into oil bath liquid and realizes spray in the spray bar 4, and eccentric wheel 22 promotion dust discharge pistons 18 move down, at this moment, when if dust concentration is big in the fluid, pressure impels dust to discharge along the exhaust port on the dust discharge pressure regulator valve 19 25, dust concentration hour, fluid then can flow to dust discharge cylinder body 17 tops along the oil guide slot on the dust discharge piston 18 24, does not carry out dust discharge work; Under the eccentric wheel effect, dust discharge piston 18 resets under the elastic force effect of spring, and therewith this moment, it is disconnected with the power supply sudden strain of a muscle that power supply dodges disconnected device, so just finished a work cycle, at this moment, and time relay reclocking, working in reciprocating mode.
