Description
Technical field
The invention belongs to municipal and environment-friendly fields.More particularly to a kind of haze purifying ball, it is mainly used for city, tunnel road two
Side, providing a kind of both can also collect a kind of multi-functional haze ball of rubbish except haze removing and harmful gas.
Background technique
Being showing improvement or progress day by day and develop with society, the living standard of people is higher and higher, but the following environment
Problem is also increasing, and in recent years, especially autumn and winter, influence of the haze to the production and living of people can not be ignored, especially
It is to child, pregnant woman, asthma patient and old man, respiratory disease more frequent and multiple, in order to solve the problems, such as that it is more that haze takes
Kind ways and means, use clean energy resource from source first, reduce discharge, reduce the dust recycling of construction site；Furthermore it uses
The method of Passive Defence frequently sprinkles water to ground using sprinkling truck, eliminates dust from land surface, and there are also sprayed using vehicle-mounted water mist
It spills, eliminates the dust in road surface overhead, such method is difficult to solve the problems, such as infringement of the haze to people in people's life；Traditional outdoor
Haze purifier is mobile inconvenient, has a single function, figure not enough goes to industrialize.
Summary of the invention
The present invention, which provides, removes haze good dedusting effect, a kind of haze purifying ball at low cost.
A kind of haze purifying ball, including support column, dustbin, it is characterized in that support column by ground pass through dustbin with combine
Ball connection；The combined spheres by bolt, bolt, pressing plate, rubber pad, blade, lower chock, outer shaft, support column, classification garbage can,
Hose clamp, upper chock composition.
Outer shaft is on the support columns in the support shaft in portion；The top and the bottom of blade are separately mounted to the upper and lower side supporting plate of outer shaft
Locate, installing component is successively blade, upper chock, rubber pad, pressing plate upwards at the supporting plate of upper end, is finally screwed on outer shaft using bolt
Blade top is held out against after the nut at end；It is successively lower chock, hose clamp from inside to outside at the lower end supporting plate of blade, after fixture larynx hoop
Blade lower part can be fastened；The hole of last bolt insertion support column topmost.
The support column is by ball bearing, snap-gauge, support shaft, thrust ball bearing, transition plates, support lower prop, cylinder skeleton, peace
Fill bottom plate composition；

Portability；There is snap-gauge to support ball bearing under ball bearing, snap-gauge is steel annulus, and outer diameter is less than ball bearing, and point is welded in support and turns
At axis, play the role of supporting ball bearing and limit；
Cylinder skeleton using cylinder-shaped steel structure made of fashioned iron welding, and is divided into four quadrants to support lower prop as middle part basic point
Area, the support frame as dustbin.
The installation support construction and rotational structure of outer shaft equipment blade thus, by nut, upper limit round steel, supporting plate, outer shaft
Pipe, lower limit round steel composition；Outer central siphon is the main support structure and rotational structure of outer shaft, is that a diameter and ball bearing are mating
Steel pipe, cover in support shaft, by with rotated after internal ball bearing and Contact of Thrust Ball Bearing；Supporting plate is circular ring shape steel
Plate is respectively welded at outer shaft upper and lower side, i.e. upper pallet and lower pallet, for installing blade；Upper limit round steel is round steel production
Annulus, diameter are greater than outer central siphon, are less than supporting plate outer diameter, are welded on upper pallet, play position-limiting action to blade upper end；Lower limit circle of position
Steel is the annulus of round steel production, is welded on outer central siphon, plays position-limiting action to blade lower end；Nut uses plain nut, is welded in
The top outer surrounding of outer central siphon, provides a supporting role for bolt.
Dustbin is the lower part of equipment, is mainly made of table top, door, lock, dustbin；Table top be thin plate metal plate suppress and
At being mounted on a skeleton；Door is similarly thin plate metal plate and suppresses, and there are rubbish to be put into mouth on top, is pacified using hardware hinge
On the column of cylinder skeleton subregion, the other side uses lock locking door；Dustbin is a fan-shaped steel cylinder, and cornice, which is lower than, to be put into
Open height, one shares 4, is respectively put into a skeleton, is divided into recyclable rubbish bucket and dustbin not can be recycled.
Blade is the primary structure of whole equipment, undertakes the major function carrier of haze ball, is steel or recyclable plastics
Be made plate-shaped, and whole is in sickle shaped, is mounted on the supporting plate of outer shaft, has gap at the link position of upper and lower end parts,
For being caught in limit round steel, by compressing with fastening force to fixed；In blade two sides coating haze powder, divide for adsorbing
Solve haze and pernicious gas.Blade is removable structure, periodic replacement or again coating haze powder.
Upper and lower chock is elastic material, generally rubber or nylon, and installation between the blades, plays buffering and clamps leaf
Piece effect.
Rubber pad is a circular ring shape thin slice, and rubber pad is mounted between blade and pressing plate, plays the role of buffering.
Pressing plate is doughnut-shaped steel plate, is mounted on blade and rubber pad top, to compress blade.
The nut of bolt and outer shaft matches, and holds out against pressing plate after being screwed into nut, to fix blade.
Hose clamp is installed in blade lower part opening position, for fastening blade.
Pin shaft is steel, insertion support shaft top hole in, for limiting outer shaft, to prevent outer shaft in rotary course by
It is detached to buoyancy and support shaft.
The present invention is obvious except haze dust removing effects, at low cost, dismantles, is easy to assembly.When carrying out wind, wind is generated to blade
Rotation torque makes top combined spheres start to rotate, and by the rotation of combined spheres, realizes that dust suction removes haze.The classification garbage can of lower part
Make the functional diversities of equipment.
