Description

Inhale grey sweeper
The utility model relates to a kind of suction ash clearing apparatus that is suitable for removing ground and corner ashes.
At present, the formation of the suction ash sweeper that extensively adopts in the prior art comprises the negative pressure ash suction head, deduster, blower fan or water ring vacuum pump, the negative pressure that it utilizes blower fan or water ring vacuum pump to produce directly absorbs, the dusty gas that is sucked by the negative pressure ash suction head need be through passing through negative-pressure air fan or water ring vacuum pump after the deduster purification, device must be comprehensive, indispensable, there is the complete equipment heaviness, the defective that cost is high, and the filtering material that passes through for dusty gas in the described deduster damages easily, make dusty gas directly enter blower fan or water ring vacuum pump thus, equipment damage is increased, significantly reduce its service life.In order to prevent the damage of power-equipment, just must improve the anti-wear performance of blower fan or water ring vacuum pump, deduster, it is a lot of that equipment cost is increased.Simultaneously, owing to can only utilize negative pressure work, its suction distance is limited, and equipment heaviness in addition can not satisfy the needs of actual use, in addition the possibility of secondary pollution at many occasions and cleaning position.
The purpose of this utility model is, designs the grey sweeper of a kind of suction, have simple in structure, cleaning is effective, use general characteristics of enclosing wide and long service life.
The technical solution of the utility model is, it has the band malleation to help the negative pressure ash suction head and the high-efficiency jet device of blowpipe, one end of high-efficiency jet device has outlet of negative pressure ash sucking tube and adjustable pipe, the inner extending end of adjustable pipe is connected to nozzle, described high-efficiency jet device is accommodated mixing chamber and diffuser casing, and its design feature is that the negative pressure ash suction head is inhaled grey flexible pipe through negative pressure and joined with negative pressure ash sucking tube inlet, the overhanging end of adjustable pipe joins with the source of the gas pipe that air valve is housed, and the diffuser casing outlet is connected to the malleation ash pipeline.
Make below in conjunction with accompanying drawing and to further specify.
Description of drawings: Fig. 1 is an external structure, and Fig. 2 is a high-efficiency jet device sectional structure.In the drawings:
1-high-efficiency jet device, the 8-air valve,
2-source of the gas pipe, the 9-adjustable pipe,
The 3-negative pressure is inhaled grey flexible pipe, the 10-nozzle,
4-negative pressure ash suction head, 11-accommodates mixing chamber,
5-malleation ash pipeline, the 12-anemostat,
The 6-malleation helps scavenging conduit, the outlet of 13-negative pressure ash sucking tube,
The 7-cinder catcher, the 14-anemostat.
By accompanying drawing as can be known, the utility model has the band malleation to help the negative pressure ash suction head (4) of blowpipe (6) and efficiently penetrates Stream device (1), an end of efficient fluid jetter (1) have the outlet of negative pressure ash sucking tube (13) and adjustable pipe (9) , the inner extending end of this adjustable pipe (9) is connected to nozzle (10), efficient fluid jetter (1) accommodate mixing chamber ( 11) and diffuser casing (12), its architectural feature is that negative pressure ash suction head (4) is inhaled grey flexible pipe (3) through negative pressure Join with negative pressure ash sucking tube entrance, the overhanging end of adjustable pipe (9) is with the source of the gas of air valve (8) is housed Pipe (2) joins, and diffuser casing (12) outlet is connected to malleation ash pipeline (5). Described malleation ash pipeline (5) Can be flexible pipe, also can be hard tube. Air valve (8) adopts ball valve to be advisable. Efficient fluid jetter (1) adopts Nozzle (10) can be the Laval-cavity nozzle of prior art, also can be jet rose of the prior art, list Hole high efficiency nozzle, ring type nozzle and annular ring type, orifice type nozzle, namely described nozzle is of the present utility model The scope of application. Negative pressure ash suction head (4) can adopt existing movable type or palm-type ash suction head, the malleation ash pipeline ( 5) can connect simple cinder catcher (7) or deduster.
This practicality is newly done suitable combining with efficient fluid jetter with the negative pressure ash suction head. And the former is its designer The high-performance device of succeeding in developing and patenting.
Design principle of the present utility model is, with the gas source pipe (2) of device shown in Figure 1 through the same tool of air valve (8) Have the malleation source of the gas (such as blower fan, positive pressure gas source capsule etc.) of certain pressure to join, then gas is sprayed by nozzle (10) Accommodating mixing chamber (11) (referring to Fig. 2) generation supersonic speed or subsonic gases after going out, thereby in this chamber ( 11) producing height in turns to the suction vacuum, turns to the suction vacuum and passes through negative pressure ash suction head (4) with ground or metope or other quilt The dust of cleaning face (position) or granular substance suck back to accommodating mixing chamber (11) and carry out the mixing of efficient air ash, Venturi effect by efficient fluid jetter (1) is converted to pressure energy with kinetic energy, through malleation ash pipeline (5) Dusty gas is delivered to cinder catcher (7). Adjustable pipe (9) is by adjusting its axial location, with regulate nozzle ( 10) relative position. In order to raise the efficiency, malleation helps scavenging conduit (6) to send a small amount of barotropic gas ground Dust evokes, and works in order to negative pressure ash suction head (4). For the large tracts of land cleaning, can adopt the core efficient fluid jetter (ductwork type, the feeding type of fixing a point), negative pressure ash suction head more then branch movable type, strength blow ash, sweep up dust, suction and people The modes such as worker's feeding, and the portable operation of hand fed is mainly to the cleaning of eminence material, dead angle dust.
As known from the above, the utility model is a kind of suction ash sweeper that adopts the principle of Venturi effect, and dusty gas need not to need not config set ash bucket and deduster under given conditions through the power source blower fan, and device structure is simple; Only need dispose simple and easy flue-dust retainer and deduster to the place that does not have grey storehouse, ash bucket, intermediate bin; Complete equipment is simplified greatly, carries and area coverage bigger (area that the negative pressure axle is inhaled, the simple negative pressure of malleation delivery ratio is looked after is bigger, conveying is farther), is particularly useful for the cleaning of large tracts of land ground (or metope).Effective, the applied range of its cleaning, equipment are durable in use, also can remove the granular material that contains particle.
Embodiment: according to the utility model device of structure illustrated in figures 1 and 2, the nozzle (10) in the high-efficiency jet device (1) adopts farad that nozzle, and it is wear-resisting flexible pipe that negative pressure is inhaled grey flexible pipe (3), and air valve (8) adopts ball valve, and the malleation source of the gas is provided by blower fan.
