Description

Automatic dedusting unit for air filter core

The present invention is the automatic cleaner of construction machinery papery air filtering core.

At present, the dedusting of papery air filtering core is directly to wash away with the air pump leather hose by hand, and micronic dust is flown upward everywhere, contaminated environment, and comrade's work around hindering, dust removing effects is poor.

Goal of the invention:

Now change the automatic dedusting of mechanical seal into and reduce environmental pollution, reduce the construction equipment wearing and tearing, make things convenient for dust removal operation, increase work efficiency, overcome night because of do not see can not dedusting etc. shortcoming, designed the air filtering core automatic dust.

Its housing profile is a straight tube of circle, and interior part two parts is up and down formed, and a vertical shaft is arranged in the middle of the top, axle has a pallet by the part of knocking off (filter core) on the top, it can be rotated with pallet and vertical shaft, a vertical antipriming pipe is arranged near the barrel, through support turning joint gas transmission.The tube top has a lid to prevent to stir up a cloud of dust.The bottom of tube is gear mechanism and micro air pump, and and upper isolation, the guard shield protection is arranged all around, also make the attic base of support cylinder.

Vertical antipriming pipe is fixing respectively up and down by support and turning joint, when the filter core dedusting of the model that varies in size because the turning joint effect, can with vertical antipriming pipe near or leave workpiece, and keep vertical.Also have a porous inner tube to make valve in the vertical antipriming pipe, have downward-sloping 30～60 a ° aperture to align with the antipriming pipe of outside every 5～6 centimeters on the tube wall, the compressed air in the pipe sprays dedusting through this hole.Because the return effect of spring, pipe moves up in making, and by little venthole exhaust resistance adjusting return speed, open second hole when closing top first hole, close second hole subsequently again and open the 3rd hole, microswitch is touched in porose back until closing, solenoid A is connected produce magnetic field, pipe and spring in the pulling are after this pulse current, magnetic field rapidly disappears, spring return work done again, and repeat

switch

1,2,3, actions such as 4 holes are once washed away again from top to bottom, dust is removed in the filter core slit, touches like the manual spary that circulates from top to down.

After field coil A connects; field coil B also connects subsequently and produces transient magnetic field; make the indentation of ratchet hook; hook ratchet and rotate that a tooth drives vertical shaft and workpiece rotates little lattice; continue spary filter core second groove; antipriming pipe jet dedusting simultaneously in the middle of this moment; when this pulse current rapidly disappears in magnetic field later; the ratchet hook resets because of spring tension; the antipriming pipe valve closing stops air feed in the middle of making; vertical antipriming pipe begins the air feed dedusting again, and a groove dedusting to the last finishes, and at this moment gives bit selecting by program control switch by the operator and puts and determine that shutdown still continues dedusting.

These give automatically and select knock-off gear to be made of rope sheave, pulley and weight, but it can replace and produce complicated program and gives and select body function, can also do to show workpiece what times of dedusting, and automatic stopping.When the rope sheave of vertical shaft lower end after nylon rope hangs up weight by two pulleys, promptly as the power of workpiece rotation, how many operators determines dedustings two times or three times according to the filter core binding dust, if weight is located at the 3rd position, workpiece dedusting three times continuously so becomes program control switch.When weight arrives extreme lower position, touching shutdown switch promptly quits work, and cut off the electricity supply, can also see in dust removal process where weight is, just know airtight what times of cylinder inner filter core dedusting, perhaps also having the not dedusting of how many lattice, is exactly to replace complicated display device with this weight position.

The micro air pump that is located at the cylinder bottom has a two-way switch, when factory or building site had compressed air gas source to supply with dedusting, micro air pump was not just worked, and is far or when not having the unit dedusting of air pump when the source of the gas supply, two-way switch is dialled in the confession position, and micro air pump promptly starts dedusting work.The housing of automatic dust and pallet are to make with metal, plastics, fiberglass or hardboard etc., also are embedded with two or three blocks of magnet steel above the pallet in order to fixation workpiece.

Advantage and effect:

Air filtering core is dirty more because task is busy more, does not especially see dust evening and can not dedusting, goes out car early in the morning again and uses in second day.Therefore have to allow dust suck in the cylinder of engine, the wearing and tearing of aggravation engine.Be directly to blow down dirt with leather hose by hand at present, now change the automatic dedusting of mechanical seal into, as long as filter core is placed in the deduster, press program control switch, the operator just can leave rest, automatic dust just can select program to carry out dedusting by giving, and automatic stopping, the engine air intake duct is often kept clean, reduce wear, reduce environmental pollution, alleviate operator's labour intensity.

This equipment is simple, and is easy to operate, but automaticity is very high, removes and put into workpiece by hand, and all the other are all automatic.
