Abstract

A dry-wet switching device for an efficient vacuum sweeper can be used for corresponding switching operations according to different weathers, can ensure not only operations in fine weathers, but also operations in rainy days, ensures the cleaning capability and the cleaning efficiency of the efficient vacuum sweeper, and prolongs the service life of a filter cylinder. The dry-wet switching device for the efficient vacuum sweeper mainly comprises a trash bin, a filtering bin and a blower, and is characterized in that a connection mode of a passage and passage door systems is that the wet-type passage strides over the filtering bin to be directly connected with the trash bin. During the work, if the weather is good, the two ends of the passage are respectively used for closing passage door systems, airflow containing dust enters into the trash bin from a dust extraction port, and then enters into the filtering bin after settlement, and clean air filtered by the filter cylinder is sucked out; and in case of rainy days, the passage rear door system and the passage front door system are opened, after smoothness, air can bypass a filter cylinder with a relatively greater resistance and is sucked out directly through the passage, due to rainy days, secondary dust raising pollution is not required to be worries, and damages on a filter cylinder since the rain water damps the wrinkle type filter cylinder can be avoided.

Description

A kind of efficient dust-collection vehicle is with doing wet switching device shifter

Technical field

the utility model relates to a kind of efficient dust-collection vehicle with doing wet switching device shifter, belongs to field of environment protection cleaning outfit class.

Background technology

The reinforcement of Along with people's environmental consciousness, also increasingly high to the requirement of vacuum sweeper.The client not only requires vacuum sweeper that a higher clean absorption rate, the operating rate of having relatively high expectations are arranged, requires lower noise, requires lower oil consumption, requires definitely not have reentrainment of dust to pollute, and also requires it to have the all-weather ability to work on overcast and rainy fine day of spring, summer, autumn and winter.

find that through patent retrieval the Chinese patent grant number is zl200620042370.2, and the applying date is on June 2nd, 2006, and patent name is an efficient dust-collection vehicle, and this patent discloses a kind of efficient dust-collection vehicle.Efficient dust-collection vehicle belongs to only absorbing sweeper truck, and its structure mainly comprises: suction port, trash repository, filtering cabin, blower fan and noise reduction case etc., and these structures are cascaded; During work, the inner negative pressure that forms of suction port, the air-flow that gets into along flow-guiding channel impacts ground earlier, and the ground dust of kicking up forms dust-contained airflow, and dust-contained airflow is sucked into suction port subsequently; Dust-contained airflow gets into trash repository through the conduit between suction port and trash repository, carries out gravitational settling earlier, and the larger particles in the air-flow is deposited in the trash repository; Tiny then particle gets into filtering cabin with air-flow, and the clean air after the filter cylinder in filtering cabin filters gets into the noise reduction case through blower fan, and row is to atmosphere after the noise reduction case is subdued noise.The weak point of this structure: during overcast and rainy operation, rainwater can get into filtering cabin with air-flow, drenches filter cylinder, makes the whole system resistance rise, and suction descends, and the cleaning ability of efficient dust-collection vehicle reduces, the application life of seriously reducing filter cylinder.

Summary of the invention

the utility model overcomes the deficiency of prior art; Provide a kind of efficient dust-collection vehicle with doing wet switching device shifter; Carry out corresponding handover operation to different weather; The cleaning ability and the sweeping efficiency of efficient dust-collection vehicle in the time of can guaranteeing overcast and rainy operation can prolong filter cylinder application life again.

the utility model is realized through following technical scheme.Mainly comprise: trash repository, filtering cabin, filter cylinder, blower fan is characterized in that: passage, access door system, its connected mode is: the passage that door system is housed strides across filtering cabin and directly connects trash repository.During work, if weather does not well have rainwater, with regard to the forward and backward door system of closing passage, let air communication filter silo and filter the back by sucking-off, if run into rainy weather, just open the forward and backward door system of passage, air-flow will directly pass through passage by sucking-off.The cleaning ability and the sweeping efficiency of efficient dust-collection vehicle in the time of can guaranteeing overcast and rainy operation like this can prolong filter cylinder application life again

the utility model is simple in structure, switching is quick, effect is obvious, has well solved the not high difficult point of efficient dust-collection vehicle rainy day operating efficiency, makes the real ability that possesses all weather operations of efficient dust-collection vehicle; Enlarged the region scope of application of efficient dust-collection vehicle.

Description of drawings

Fig. 1 is that efficient dust-collection vehicle is with the structural representation of doing wet switching device shifter;

Fig. 2 is the gas flow figure of efficient dust-collection vehicle with two kinds of working methods doing wet switching device shifter;

Fig. 3 is that efficient dust-collection vehicle is with the top view of doing wet switching device shifter;

The specific embodiment

are as shown in Figure 1; Mainly comprise: trash repository 2, filtering cabin 4, blower fan 6; It is characterized in that: door system 8 before door system 7, the passage behind passage 5, the passage, its connected mode is: passage 5 one ends are connected with blower fan, stride across filtering cabin 4 other ends and are connected with trash repository 2.During work, if weather does not well have rainwater, door system 7 and the preceding door system 8 of passage behind the difference closing passage of the two ends of passage 5, passage 5 has a door system control at least, and it is opened or closes; Dust-contained airflow gets into trash repository 2 from suction port 1, gets into filtering cabin 4 behind the gravitational settling, and the cleaning gas after filter cylinder 3 filters is by sucking-off; If run into rainy weather, open behind the passage door system 8 before the door system 7 and passage, unimpeded back air-flow directly through passage 5 by sucking-off.

are as shown in Figure 1: door system 7 can use compressed air, hydraulic oil or electricity to carry out work as power source according to the distribution of car load power source with the preceding door system 8 of passage behind the passage.

are as shown in Figure 1: passage 5 mainly plays the pipeline interconnect function; Can use iron pipe, iron plate or injection molded; Its cross section can be square, rectangle, circle, trapezoidal; Can select optimal scheme according to oneself equipment and prior art, its position is for striding across from the filtering cabin top.
