Abstract
The utility model provides an air filtering device which comprises a blower, an air inlet passage, a multi-tube cyclone dust collector, a dust collecting box and a dust discharge passage, wherein a filter net is arranged at the inlet of the air inlet passage; the dust discharge passage is connected with the dust collecting box; the air inlet passage directly faces to the air inlet of the multi-tube cyclone dust collector; the dust collecting box is positioned below the multi-tube cyclone dust collector and used for receiving particle dust; the air suction opening of the blower is connected with the purified air outlet of the dust collector. According to the air filtering device provided by the utility model, dust particle of air containing dust is filtered out through the dust collector, the purified air enters the blower again, so that abrasion of the blades of the blower is avoided, the air passage is not blocked, the service life of the blower is prolonged, and the efficiency of the blower is improved.
Description
Technical field
The utility model relates to a kind of air filter, especially for the air filter on the cleaning equipments such as road sweeper.
Background technology
The use of road sweeper has improved the operating efficiency of road cleaning, has improved manual labor.Road sweeper is divided into wet dust removal and dry dust removal.Adopt wet dust removal, wherein can be divided into again water spray dedusting and circulating water dedusting; But, but cannot water under a lot of situations process the problem of dust removal and filtration, the collection of analogy cement, powdered carbon, metal mining powder.Even sweeping of avenue, when Dust Capacity is larger, too much watering amount also can make dust meet water knot mud, and it is difficult to sweep and dump.
Chinese patent ZL200820173513.2 has disclosed a kind of dry-type road sweeper air cleaning device, it is by centrifugal blower, multicyclone, plate type air filtration purifier, return air and refuse collector form, the air intake of centrifugal blower connects return air refuse collector, the air intake of centrifugal blower connects return air refuse collector, the air outlet slit of centrifugal blower is connected with the inlet (dust contained gas) of multicyclone, the control of dust pour spout of multicyclone connects the sweeping machine garbage collection box of return air and refuse collector, the control of dust pour spout of multicyclone connects the sweeping machine garbage collection box of return air and refuse collector, air outlet slit connecting plate type air filtering purifier air intake after the dedusting of multicyclone, air part discharge atmosphere after purifying, the blowing mouth that another part connects return air and refuse collector recycles.The shortcoming of this air cleaning unit is: have granule dust first through blower fan, to arrive deduster, particle must increase fan blade and inner wearing and tearing, greatly reduces fan efficiency and service life again.
Summary of the invention
In order to overcome the above-mentioned shortcoming of prior art, the utility model provides a kind of granule dust of can avoiding to enter blower fan, improves the air filter of fan efficiency and prolongation service life of fan.
, comprise blower fan, air intake passage, multicyclone, disposal box and dust discharge passage, the entrance of air intake passage is provided with screen pack, and dust discharge passage is communicated with disposal box; It is characterized in that: air intake passage is aimed at the air intlet of multicyclone, and disposal box is positioned at the below of multicyclone and accepts granule dust; The air entry of blower fan is connected with the clean air outlet of deduster by air channel.
Further, the dedusting module that deduster comprises shell and is comprised of dust removing tube, shell upper end and air channel are tightly connected, shell hypomere and disposal box are tightly connected, shell front end is connected with air intake passage, disposal box is a cylindrical shell, cylindrical shell one side and dust discharge channel connection, and this cylindrical shell opposite side is the slope of dust discharge passage that granule dust is led.
Further, dedusting module comprises dust removing tube, the fixedly upper mounting plate on dust removing tube top and the fixedly lower installation board of dust removing tube bottom, dust removing tube is vertical with two installing plates, dedusting module fixing with shell in.
Further, the dust-exhausting port of dust discharge passage is provided with pneumatic operated valve.
During the utility model work, start blower fan, the suction of blower fan makes the air with granule dust enter from air intake passage, and screen pack plays dust-filtering effect for the first time.The air with granule dust then enters in dedusting module, and dusty gas is in the rotation of dust removing tube inner high speed, under the effect of centrifugal force, dust is separated with gas, dust drops in disposal box, and the gas of purification forms the eddy flow rising and converges in air channel, then discharges through blower fan.Slope is by the dust dust discharge passage that leads, and when pneumatic operated valve is opened, dust discharges.
In the utility model, dust laden air first passes through deduster filtering dust particle, and the air after purification enters blower fan again, avoids the fan blade that weares and teares, and also can not stop up air channel, has extended the service life of blower fan, improves fan efficiency.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is the decomposing schematic representation of Fig. 1.
Fig. 3 is that the utility model is installed on the schematic diagram on sweeper.
The specific embodiment
In conjunction with Fig. 1-3, further illustrate the utility model:
, comprise blower fan 1, air intake passage 2, multicyclone 3, disposal box 5 and dust discharge passage 6, the entrance of air intake passage 2 is provided with screen pack 4, and dust discharge passage 6 is communicated with disposal box 5; Air intake passage 2 is aimed at the air intlet of multicyclone 3, and disposal box 5 is positioned at the below of multicyclone 3 and accepts granule dust; The air entry of blower fan 1 is connected with the clean air outlet of deduster 3 by air channel 8.
The dedusting module that deduster 3 comprises shell 31 and is comprised of dust removing tube 32, shell 31 upper ends and air channel 8 are tightly connected, shell hypomere and disposal box 5 are tightly connected, shell front end is connected with air intake passage 2, disposal box 5 is a cylindrical shell, cylindrical shell one side is communicated with dust discharge passage 6, and this cylindrical shell opposite side is the slope 51 of dust discharge passage 6 that granule dust is led.
Dedusting module comprises dust removing tube 32, the fixedly upper mounting plate on dust removing tube 32 tops and the fixedly lower installation board of dust removing tube 32 bottoms, dust removing tube 32 is vertical with two installing plates, dedusting module fixing with shell 31 in.
