The back-blowing system adopts an independent fan, and has smaller power compared with a main suction fan; the fan takes air from the sweeping disc to enter air, and is directly connected with the air suction channel of the fan through a pipeline without passing through the box body, so that the wind loss can be effectively reduced; the air exhaust of the fan is directly led to the back flushing port of the suction nozzle through the exhaust duct of the fan, and the back flushing effect is better.
Description
Technical Field
The utility model relates to a sanitation machinery especially relates to independent fan suction nozzle blowback system.
Background
In the prior art, a suction nozzle blowback technology is commonly used for a dust collection vehicle and a dry type sweeping machine, namely, an air suction channel of a main shaft suction fan is used for sucking air from a suction nozzle into a box body, and then air in the box body is blowback to a suction disc from an air exhaust channel to assist the suction nozzle in sucking and picking up garbage. The disadvantages caused by the prior art are as follows: 1. the suction force of the fan to the sucker is influenced by shunting; 2. the reverse blowing easily causes unsmooth air exhaust of the fan and influences the efficiency of the fan.
Disclosure of Invention
The utility model aims at providing a smooth and easy independent fan suction nozzle blowback system of blowback.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
independent fan suction nozzle blowback system, including suction nozzle and two sets of dishes of sweeping, two sets of dishes of sweeping set up respectively in the both sides of frame, and it still includes the fan, has the inlet scoop on respectively sweeping the roof of dish respectively, and each inlet scoop is respectively through the suction channel of pipe connection to fan, the exhaust airway of fan is through the blowback mouth of pipe connection to suction nozzle top.
Further, the fan is a centrifugal fan.
Furthermore, every group is swept the dish and is had the dish of sweeping more than two respectively, and the dish of sweeping of the same group is connected to the induced draft of fan through an induced draft pipe and says and be connected, the one end of induced draft pipe and the induced draft of fan say and be connected, and the other end of induced draft pipe corresponds the dish of sweeping respectively of the same group and forms the branch pipe that induced drafts, and each branch pipe that induced drafts is connected with the inlet scoop that sweeps on the dish with corresponding.
Furthermore, the top of the suction nozzle is provided with a plurality of back blowing ports, each back blowing port is connected to an exhaust duct of the fan through an exhaust duct, one end of the exhaust duct is connected with the exhaust duct of the fan, the other end of the exhaust duct is branched to form a plurality of exhaust branch pipes, and each exhaust branch pipe is connected with the corresponding back blowing port respectively.
The utility model adopts the above technique, following beneficial effect has:
1. the back-blowing system adopts an independent fan, and has smaller power compared with a main suction fan; the fan takes air from the sweeping disc to enter air, and is directly connected with the air suction channel of the fan through a pipeline without passing through the box body, so that the wind loss can be effectively reduced; the air exhausted by the fan is directly led to the back flushing port of the suction nozzle through the air exhaust duct of the fan, so that the back flushing effect is better;
2. the blower can suck the dust at the sweeping disc while taking gas from the sweeping disc, so that the dust of the whole vehicle is reduced;
3. compared with the traditional dust removal scheme, the dust removal device has no influence on the main suction fan, namely, the suction force is not shunted, and the problem of unsmooth air exhaust is avoided.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments;
fig. 1 is a schematic view of the present invention.
Detailed Description
As shown in fig. 1, the utility model discloses independent fan suction nozzle 1 blowback system, including suction nozzle 1 and two sets of dishes 2 of sweeping, two sets of dishes 2 of sweeping set up respectively in the both sides of frame, and it still includes fan 3, respectively sweeps and has the inlet scoop on the roof of dish 2 respectively, and each inlet scoop is respectively through pipe connection to fan 3's suction channel 31, fan 3's exhaust airway 32 is through the blowback mouth at pipe connection to suction nozzle 1 top.
Further, the fan 3 is a centrifugal fan.
Every group is swept set 2 and is had two or more than sweep set 2 respectively, and the same group is swept set 2 and is connected to the induced draft of fan 3 through an induced draft pipe 4 and say 31, the one end of induced draft pipe 4 is connected with the induced draft of fan 3 and says 31, and the other end of induced draft pipe 4 corresponds and respectively sweeps set 2 and form the branch pipe that induced drafts respectively with organizing, and each branch pipe that induced drafts is connected with the inlet scoop that corresponds on sweeping set 2.
The top of the suction nozzle 1 is provided with a plurality of back blowing openings, each back blowing opening is connected to an exhaust duct 32 of the fan 3 through an exhaust duct 5, one end of the exhaust duct 5 is connected with the exhaust duct 32 of the fan 3, the other end of the exhaust duct 5 is branched to form a plurality of exhaust branch pipes, and each exhaust branch pipe is respectively connected with the corresponding back blowing opening.
The utility model discloses in, suction nozzle 1's suction opening is connected to main suction fan and is used for suction nozzle 1 to inhale and pick up rubbish, and centrifugal fan then uses suction nozzle 1's blowback.
The utility model discloses a theory of operation: the aspiration channel 4 gets the gas air inlet from sweeping disk 2, can suck 2 punishment of sweeping disk raise dust when getting gas, reduces whole car raise dust, and the air current inhales from air suction channel 31, through centrifugal fan, discharges to 1 blowback mouth of suction nozzle through exhaust pipe 5 by exhaust duct 32 to reach 1 blowback of suction nozzle, improve the effect that suction nozzle 1 cleaned the clean rate.
The practice of the present invention has been described with reference to the accompanying drawings, but the invention is not limited to the embodiments described above, which are illustrative rather than limiting, and it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not substantially depart from the scope of the embodiments of the present invention, and are intended to be covered by the claims and the specification.
