Description
Technical field
The present invention relates to a kind of blower fan made in cylinder body with piston circulation compression and rotated, the knot of conventional fan is changed
Structure, it is suitable for the road sweeper of dry suction and the wet suction of big suction flow.
Background technology
At present, the dust suction of road sweeper is all using kinetic energy of the centrifugal blower as suction, in order to increase centrifugal blower
Suction, the quantity of fan blade can only be increased and increase the power with engine to improve the rotating speed of centrifugal blower, centrifugal blower is at least up to
Dust suction requirement is substantially met to more than 2000 turns.Dry suction road-cleaning dedusting must install multi-layered high-density in the front end of suction inlet
Screen pack, after screen pack is blocked by dust or other dust, due between fan blade on blower fan there is spacing, when being produced outside suction inlet
After raw certain resistance, the fan blade of blower fan is likewise as the driving quick rotation of engine, suction still very little caused by blower fan,
Not only consume the power of engine, and blower fan in quick rotation because air swirl produces great noise.
The content of the invention
Not the problem of not reaching dedusting suction for above-mentioned road sweeper draught fan matching.The present invention provides a kind of twin-tub circulation
Drawing-in type blower fan, it is rotated using two pieces of forward and backward cylinder pistons works with arc are synchronized in the same direction, and combines turn of a circle covering of the fan
Valve is changed, makees synchronized counter steer rotation, to automatically control the intake and exhaust of front and rear cylinder, so as to produce great suction force.
The technical solution adopted for the present invention to solve the technical problems is：In the plate face of metal or other materials, by institute
The blower fan specification needed draws an isoceles triangle, draws two diameter identical circles, the circle of drawn circle respectively using isosceles base angle as the center of circle
Side face can be with overlapping or separation, and draws a roundlet respectively on the center of circle, and small diameter of a circle is slightly larger than the diameter of required rotary shaft,
Using etc. the intersecting point of waist edge as the center of circle.The center of circle to the length of the small round edge of inferior horn draws a circle as radius.Will with special equipment
Respective periphery is cut off, and forms two pieces of semicircles with arc notch and one piece of full circle.With another three pieces of same method cutting.By two
The notched semicircle of block, is welded with the thin plate of one piece of phase same material, forms a circle cylinder body with arc notch.In circle cylinder
Two rectangle holes are opened at the breach cambered surface of body respectively, as air inlet and exhaust outlet.The long square opening of two round cylinder bodies is carried out
Connection, form a rectangular air entry and an exhaust outlet.By the thin plate of two pieces of full circle phase same materials, the height of making
With circle cylinder body it is identical, welding formed a circle cylinder, on the periphery of thin plate junction, open a central angle for 100 degree extremely
160 degree of opening is welded with rotating shaft as switching valve and is processed into concentric circles.Cylinder piston, length are slightly short before and after doing two pieces
Bottom level, width can just be rotated by rotating shaft in cylinder body up and down on the inside of switching valve, be fabricated to the piston with arc surface
In rotating shaft.The both sides of twin-rotor housing connect support respectively, install three bearing blocks on support, the position of bearing block with before
The isosceles triangle size of cyclotomy is identical, installs three bearing blocks respectively on the center of circle of triangle.One piece of support is solderable be connected to it is double
Side of cylinder block, another piece movable can be dismantled, and be easily installed front and rear piston and switching valve.Front and rear cylinder piston and switching valve will be made
In support, the cambered surface of front and rear piston is supported positioning towards exhaust outlet direction with bearing, bearing block, can be in twin-rotor housing
Inner chamber can freely rotate.Ensure that fan operation is steady.On three axles outside bearing block, balance weight is installed respectively, in installation 90
Before degree commutation gyrator, the position of forward and backward cylinder piston and switching valve is adjusted.Preceding cylinder piston is gone into the following of air entry
Mouthful, the covering of the fan opening surface of switching valve turns to the top mouth of air entry, and rear cylinder piston goes to the following of exhaust outlet, then changed with 90 degree
Three rotating shafts are positioned to gyrator, rotating switching valve makes it not collide mutually, covers protective cover, is installed in switching valve rotating shaft
Belt pulley.
The beneficial effects of the invention are as follows：Very big suction force, the engine power of adapted can be produced in blower fan low-speed running
It is small, by the cycle operation of twin-tub, the power of engine can be completely converted into wind energy, energy-conservation is obvious.The fan noise is low, knot
Structure is simple, working stability.
