Background technique
At present, the empty filter of existing heavy-duty car commonly used will be removed the dust of filter cleaner the inside; Just must carry out dismounting, carry out dedusting through manual work, this is for the vehicle of working down at high concentration dust environment (like mine, desert region); Will certainly waste many times and thought because of the dedusting of empty filter; And in disassembly process, probably empty filter is caused damage, wasted driver's time and money.
Summary of the invention
The technical problem that the utility model will solve is: provide a kind of blowing-type automatic dust-collecting air filter cleaner, when making dedusting without dismounting.
In order to solve the problems of the technologies described above; The utility model comprises housing, main filter core and safe filter core, is provided with rectifying cavity between described main filter core and the safe filter core, and rectifying cavity is provided with vent; Vent is provided with the guide plate that steering flow flows to main element wall; Rectifying cavity is connected with cylinder through tracheae, and lower part of frame is provided with duckbill Valve, is provided with the blower fan of air flow direction duckbill Valve in the guide housing in the housing.
For the dust removal operation convenience; Described blower fan is a vortex fan; The motor of vortex fan is arranged on outside the housing; Tracheae is provided with solenoid valve, and solenoid valve and motor are provided with the push-button switch of the control system break-make of control time relay by relay control at the same time in the control system of the time relay.Make the work of tracheae air blast and the work of motor drifting dust carry out synchronously, and the work of prescribing a time limit.
For making rectifying cavity simple in structure, easily manufactured; Described rectifying cavity comprises two ring flat-plates and two cylindrical shells between main filter core and safe filter core; Has a determining deviation between two ring flat-plates; The cylindrical of two ring flat-plates and interior circle are separately fixed on two cylindrical shells, and two cylindrical shells are separately fixed on main filter core and the safe filter core, are equipped with described vent on two ring flat-plates.
The utility model beneficial effect: the utility model is provided with rectifying cavity and tracheae between main filter core and safe filter core; Rectifying cavity is provided with pore and guide plate; Get gas through tracheae from cylinder, through the guide plate on the rectifying cavity main filter core is carried out air blast again, thereby dust is come off.Be provided with duckbill Valve in empty filter lower housing portion,, make duckbilled open, blow out dust through the work of vortex fan.Realized exempting from the function of the automatic dedusting of dismounting.

Embodiment
A kind of specific embodiment as shown in Figure 1; It comprises housing 14, main filter core 10 and safe filter core 9, and main filter core 10 is arranged in housing 14 with safe filter core 9, and safe filter core 9 is arranged in main filter core 10; Housing 14 is provided with suction port 13, and safe filter core 9 is provided with air outlet 15.More than describe is the structure of existing air-strainer.
The utility model is on the basis of said structure, to increase following dust removal apparatus.
As shown in Figure 1; Be provided with rectifying cavity 11 between main filter core 10 and the safe filter core 9, as shown in Figure 2, rectifying cavity 11 comprises two ring flat-plates and two cylindrical shells between main filter core 10 and safe filter core 9; Has a determining deviation between two ring flat-plates; The cylindrical of two ring flat-plates and interior circle are separately fixed on two cylindrical shells, and two cylindrical shells are separately fixed on main filter core 10 and the safe filter core 9, are equipped with described vent 16 on two ring flat-plates.Be equipped with the guide plate that steering flow flows to the wall of main filter core 10 on each vent 16; Rectifying cavity 11 is connected with cylinder 1 through tracheae 2; The bottom of housing 14 is provided with duckbill Valve 7; Be provided with the vortex fan 6 of air flow direction duckbill Valve 7 in the guide housing 14 in the housing 14, the motor 8 of vortex fan 6 is arranged on outside the housing 14, and tracheae 2 is provided with solenoid valve 3; Solenoid valve 3 and motor 8 are provided with the push-button switch 12 of control control system break-make by relay 4 controls at the same time in the control system of the time relay 4.
Working principle:
Dedusting: suction port 13 is closed with air outlet 15, and start button opens 12, makes the quilt control system conducting of the time relay 4; Thereby control electromagnetic valve 3 is opened with motor 8; Cylinder 1 is to rectifying cavity 11 inflations, and during dedusting, air-flow is pressed airflow direction arrow 5 directions and flowed; Through the guide plate on the rectifying cavity 11 wall of main filter core 10 is carried out air blast, dust comes off from main element wall; On the other hand, motor 8 drives vortex fan 6 work, produces the pressure greater than duckbill Valve 7 cracking pressures 7 one of duckbill Valves, opens duckbill Valve 7; In the other end, produce a negative pressure, thereby let the blown off dust of main element wall flow to duckbill Valve 7; And through duckbill Valve 7 discharges, the time arrives the time relay 4 disconnections to the time relay 4 in limited time; Dust removal mechanism quits work; The purpose of the automatic dedusting of dismounting is exempted from realization, has alleviated driver's work greatly, has also reduced the probability of the artificial damage of air-strainer.
Air-strainer is when proper functioning, and air can flow into from suction port 13, and 15 flow out from the air outlet.
