Abstract

The utility model relates to a wholly-sucking dust sucking car which changes the conventional mode that an old sweeping car sweeps with a brush and a rolling brush; the wholly-sucking dust sucking car complete work wholly with airflow without using a brush and spraying water. A centrifugal impeller is installed in the wholly-sucking dust sucking car. When the centrifugal impeller rotates, dust is driven by the airflow to be sucked into the centrifugal impeller through a suction pipe. The dust and air are separated by centrifugal force which is produced when the centrifugal impeller rotates. After the dust and the air are separated, the dust is stored into a dust box. The air is blown out from a seam on the peripheral edge of a dust sucking disc to blow the dust on the ground, and then the dust is sucked in by the suction pipe. The utility model can be used for removing the dust and impurities on the ground.

Description

Wholly-sucking vacuum sweeper

The present invention relates to a kind of Wholly-sucking vacuum sweeper, this kind vacuum sweeper uses at highway and the ground cleaning work that a large amount of dusts and foreign material are arranged.

As everyone knows, existing road-sweeper all be unable to do without " a sweeping " word, be to adopt brush to roll to carry out sweeping, dish brush with circle is swept to ground refuse middle, with blower fan rubbish is sucked ash bin then, in ash bin, press the way of dirt that the bulky grain thing is precipitated by gravitational settling, water spray, and some thin dust waft along with the discharge of gas to aerial, in cleaning process in order to prevent that airborne dust from wanting continual and spraying water with brush earthward, but the result is a dust not to be and to have become mud, adhere to exactly on the ground, wait water one dry ash dirt is again to wave everywhere in the same old way; Therefore existing road-sweeper can't be removed ground fine dust effectively, owing to will spray water, has not only wasted water resource, north of china in winter can not operation but also is existed the brush serious wear, to often change defectives such as brush, maintaining difficulty, usage charges height.

The purpose of this invention is to provide and a kind ofly do not spray water the Wholly-sucking vacuum sweeper of all finishing during operation without brush with air-flow.

Wholly-sucking vacuum sweeper of the present invention comprises a walking car, load a dust exhaust apparatus on the car, its structure is to be rotated at a high speed by the gasoline engine impeller, interlobate gas also obtains centrifugal force with the impeller rotation, therefore gas begins to flow, the gas that flows drives dust and together is sucked into impeller, in impeller, obtain energy and got rid of into casing with certain speed and pressure, dust is made circular motion in casing, leaning on centrifugal intertia force to be got rid of into from the casing outlet again stores in the ash bin, gas in casing then enters the dust suction dish under the guiding of guide ring leaf guide card, and then from dust suction dish seam on every side, blow out to the centre, can blow to ground dust and foreign material in the central suction pipe this moment, sucked by impeller again.In this circulation, play the purpose of absorbing ground foreign material and dust.

Below in conjunction with embodiment and accompanying drawing, describe in detail.

Fig. 1, the full sectional view of Wholly-sucking vacuum sweeper of the present invention.

Fig. 2 is the A-A sectional drawing of Fig. 1.

Fig. 3 is the cross section detail drawing of air-jeting disk.

(on the motor tricycle vehicle carriage) installs a dust exhaust apparatus on the car body 1 of a dynamic driving, and casing 2 is wherein arranged, and its casing inner wall is circular.In order to prevent the wearing and tearing of sandstone to casing, the abrasionproof liner plate is housed on casing inner wall, this liner plate can be divided into several, fixes with bolt and casing, and motor or motor 3 are housed above casing, drives the impeller 4 that is contained in bottom and together rotate when engine running.In order to prevent that sandstone wearing and tearing are equipped with wear strip too on impeller blade, and for the impeller of the handling capacity design of strengthening foreign material shroud not to be installed be centrifugal half-opened impeller.An air inlet pipe 5 is arranged under impeller,, and get rid of in the ash bin 6 of back by outlet obviously because the impeller rotation makes air motion, and air-flow drives dust and enters impeller by air inlet pipe 5, makes centrifugal circular motion then in casing 2.Guide ring 7 also is housed below the impeller in casing 2, its guide ring is circular, by last, the circular steel plate 8 of following two band certain taper is formed with several pieces flow deflectors 9, in air-flow rotatablely moves, flow deflector can make air-flow become radial motion by circular motion, become axially-movable at last, and stream pressure is increased, air-flow enters under the guiding of flow deflector 9 in the mounted dust suction dish 10 in casing bottom, the dust suction dish is circular, cracking of a circumferential arranged around its underpart, crack and there is certain setting angle on ground, air-flow blows afloat the dust on ground by this angle to be arrived in central authorities and by suction pipe 5 it is sucked up.Can increase some air nozzle 11 (see figure 3)s and can make of rubber in the dust suction right both sides of facing left in order to enlarge the dust suction area, and can fix with anchor ear and dust suction dish for this air nozzle that prevents to damage.On dust suction dish 10, can glue some flexible glue skins 12, this flexible glue skin is concordant with ground, can prevent effectively that air nozzle 11 from blowing afloat floor-dust, plays the effect of pressing dirt.

When work,, motor 3 produces very big heat because understanding, influenced the normal operation of motor, in order to address this problem, in the ash bin 6 of back of the present invention, a sack cleaner 13 is housed, this kind deduster is made up of a plurality of cloth bags, and is supported by steel wire net rack, and gas is blown out on the motor by the jet pipe 14 before the ash bin of back after filtering, thereby cooled off motor, on the ash bin of back, back pullout (BPO) 15 has been housed also and can opens the evacuation of dirt foreign material.

Vacuum sweeper of the present invention is through becoming the vacuum sweeper of multiple model after changing.If change the motor tricycle car body of dynamic driving into car body, just can make the Wholly-sucking vacuum sweeper of truck mounted into by the automobile chassis formula; The power cancellation will become the hand propelled Wholly-sucking vacuum sweeper again if will walk; Change motor into motor, just can repack the electrodynamic type vacuum sweeper into.

Characteristics of the present invention and purposes

Wholly-sucking vacuum sweeper all fulfils assignment with air-flow, makes air-flow high-speed circulating in a close passage, no gas Spill, so dust removal efficiency can reach more than 98%, owing to cancelled brush, structure be become simply, bring convenience to maintaining, Saved usage charges, owing to be to do suction, need not spray water again, saved water resource, and the north of china in winter operation that does as usual is (anhydrous Be not afraid of icing). Therefore Wholly-sucking vacuum sweeper can be used in the place of a large amount of dust and foreign material, can remove in factory The cleaning work of iron filings, aluminium bits alleviated swabber's labour intensity, and no reentrainment of dust has reduced containing of dust in the air Amount has improved the health level in city.
