Abstract
A jet vacuum absorbing and sweeping device comprises an ejector (2) and a first nozzle (8), wherein the ejector (2) and the first nozzle (8) are respectively connected with a high pressure air source by a pipeline with a valve, an air suction device for absorbing garbage is also connected to the ejector (2), and a garbage collector is arranged at the outlet end of the ejector (2). The jet vacuum absorbing and sweeping device has the advantages that the ejector is additionally arranged at the outlet of the high pressure air source, such as a fan, a compressor or a high pressure air tank, and negative pressure is generated by the ejector, so that an air current containing the garbage, sucked by a sucker cannot be in contact with the fan or the compressor, but directly enters the garbage collector. The work condition of the fan or the compressor is improved, a filter device arranged in front of the fan or the compressor is omitted, and the work efficiency of the fan or the compressor is improved.
Description
Technical field
The utility model relates to the suction sweeping device, and a kind of jetting stream vacuum is inhaled sweeping device specifically.
Background technology
Sweeping machine as one of sanitation equipment, is a kind of new and effective cleaning equipment that integrates road cleaning, garbage reclamation and transportation.Be widely used in the road-cleanings such as arterial highway, municipal administration and airfield pavement, uptown, park.Sweeping machine has greatly reduced sanitationman's working strength, has improved operating efficiency, has reduced the secondary pollutions such as airborne dust.
The kind of sweeping machine is a lot, generally is divided into cleaning formula and vacuum dust-absorption sweeping type two classes.The advantage such as have than the sweeping machine of common cleaning formula that the work travel speed is fast, sweeping efficiency is high due to the vacuum dust-absorption sweeping type and environment pollution is little is current development than a class sweeping machine faster.The vacuum dust-absorption sweeping machine is swept dish by the left and right rubbish of both sides is swept to suction nozzle under car/sucker the place ahead, carries out the road surface cleaning by inhaling sweeping device.The operating principle of inhaling sweeping device is to make by blower fan in the air channel of the compositions such as suction nozzle/sucker and dustbin to produce high velocity air, and under the effect of air-flow and low pressure, rubbish is inhaled into suction nozzle/sucker, sends in Material collecting box for harvesting.Along with sweeping machine is walked forward, the rubbish that is swept to suction nozzle/sucker the place ahead constantly enters into suction nozzle/sucker, and is drawn onto continuously in Material collecting box for harvesting, realizes the cleaning on road surface.
It is the main device of above-mentioned vacuum dust-absorption sweeping machine that vacuum is inhaled sweeping device, and blower fan is the key component that whole vacuum is inhaled sweeping device.Sucker relies on the negative pressure that blower fan produces to suck rubbish at blower fan foremost.Do not filtered if contain the air-flow of rubbish the blower fan of directly flowing through, caused the blower fan damage.For guaranteeing the blower fan normal operation, must purify the air-flow of the blower fan of flowing through, therefore need to increase the multi-filtering device at the blower fan front end, thereby elimination makes the air of the blower fan of flowing through enough clean from rubbish and dust that suction nozzle/sucker sucks in.Thereby reduce fan efficiency but filter can increase the resistance of runner, and for the maintenance of filter or use cost and the reliability of replacing meeting increase road sweeper.
The utility model content
The purpose of this utility model is to provide a kind of simple in structure, with low cost, jetting stream vacuum of increasing work efficiency and inhales sweeping device.
A kind of jetting stream vacuum is inhaled sweeping device, comprise: ejector 2 and the first nozzle 8, described ejector 2, the first nozzle 8 are respectively by being with valvular pipeline to be connected with high-pressure air source, also be connected with on described ejector 2 for the getter device that absorbs rubbish, the port of export of described ejector 2 is provided with material-gathering device.
Described ejector 2 comprises a mixing tube with mixing chamber 24, establishes the second nozzle 23 that is connected with high-pressure air source in described mixing tube, and the mixing tube side also is provided with for the rubbish intake 21 that is connected with getter device; Described mixing chamber 24 is connected with trunnion 25 and anemostat 26 in turn, and described anemostat 26 is connected with described material-gathering device.
Described getter device comprises sucker 4 and is used for being communicated with the rubbish suction pipe 3 of sucker 4 and intake 21.
Described material-gathering device is storage case 5, and storage case 5 tops are provided with the short tube 7 of giving vent to anger, and the junction of storage case 5 and the short tube 7 of giving vent to anger is provided with filter screen 6.
Described mixing chamber 24 is back taper or inverted tubaeform.
The advantage that the utility model jetting stream vacuum is inhaled sweeping device is:
1, simple in structure, with low cost, can be applied on the cleaning carts such as sweeping machine;
2, reliable operation produces vacuum by ejector, and no-rotary part reduces the parts damages probability, increases the service life;
3, dual-use material can be inhaled sweeping device by vacuum and suck and collect rubbish, also can blow a small amount of rubbish open by nozzle and sweep, purges two kinds of functions to keep the road surface cleaning, to integrate inhaling.
The utility model jetting stream vacuum is inhaled sweeping device, install ejector additional in the outlet of the high-pressure air source such as blower fan, compressor or high pressure gas holder, produce negative pressure by ejector, the air-flow that contains rubbish that therefore sucks by sucker can not contact blower fan or compressor, but directly enters refuse collector.Thereby make the condition of work of blower fan or compressor improve, and saved the filter before blower fan or compressor, improved the operating efficiency of blower fan or compressor.
Itself does not have rotatable parts ejector, have simple in structure, handling ease, good airproof performance, be convenient to the advantages such as maintenance, and the higher vacuum of generation that can continue, when making the utility model contain the pavement garbage such as rubble, branches and leaves in extraction, have unique advantage.
Description of drawings
Fig. 1 is the structural representation that jetting stream vacuum is inhaled sweeping device.
Fig. 2 is the structural representation of ejector.
Wherein: 1 is the second valve, and 2 is ejector, and 3 is the rubbish suction pipe, and 4 is sucker, and 5 is storage case, 6 is filter screen, and 7 are the short tube of giving vent to anger, and 8 is the first nozzle, and 10 is the first valve, and 21 is the rubbish intake, 23 is second nozzle, and 24 is mixing chamber, and 25 is trunnion, and 26 is anemostat.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated: as shown in Figure 1 and Figure 2, a kind of jetting stream vacuum is inhaled sweeping device, comprise: ejector 2 and the first nozzle 8, described ejector 2, the first nozzle 8 are respectively by being with valvular pipeline to be connected with high-pressure air source, also be connected with on described ejector 2 for the getter device that absorbs rubbish, the port of export of described ejector 2 is provided with material-gathering device.
