Abstract
The utility model discloses a prefilter formula diesel engine air cleaner is including the air cleaner assembly that is equipped with air inlet, dust exhaust ware and gas outlet, still including the casing that is equipped with air intake, prefilter dust exhaust mouth and prefilter gas outlet, all locate impeller, dust separation circulator and the dust collection board in the casing, impeller is located the air intake below, dust separation circulator is located impeller below, the dust collection board is located the outside of dust separation circulator, prefilter dust exhaust mouth is located the dust collection board below, prefilter gas outlet with the air inlet intercommunication. And the air filter assembly is also provided with a safety indicator. The utility model discloses an increase pre-filtering device, can go out the large granule impurity separation in the air to avoid blockking up the air cleaner assembly, this air cleaner filters efficiently, long service life.
Description
Technical field
The utility model relates to the air-strainer field, is specially a kind of pre-flock formula air filter for diesel engine.
Background technique
The employed air-strainer of present anti-explosion diesel engine for mine generally only has one-level or two-stage fine-filtering device, namely do not have the pre-flock device, still, the large granular impurity through pre-flock does not easily stop up air cleaner assy, thereby cause filtering efficiency low, easily cause engine scuffing.
Summary of the invention
The purpose of this utility model is to provide in order to overcome above-mentioned deficiency that a kind of simple in structure, filtering is efficient, the pre-flock formula air filter for diesel engine of long service life.
The utility model comprises the air cleaner assy that is provided with suction port, dust exhaustor and air outlet, also comprise the housing that is provided with intake grill, pre-flock dust exhaust port and pre-flock air outlet, all be located at eddy flow impeller, dust separation rotor and dust-collecting plate in the housing, described eddy flow impeller is positioned at the intake grill below, described dust separation rotor is positioned at eddy flow impeller below, described dust-collecting plate is positioned at the outside of dust separation rotor, described pre-flock dust exhaust port is positioned at the dust-collecting plate below, and described pre-flock air outlet is communicated with described suction port.
Also be provided with safety indicator in the described air cleaner assy.
The utility model is by increasing the pre-flock device, airborne large granular impurity can be separated, thereby avoid stopping up air cleaner assy, and be provided with safety indicator, when air cleaner assy was stopped up, safety indicator will give the alarm, and prompting needs to clean or change, so this air-strainer filtering efficiency is high, long service life.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1-air cleaner assy (11-suction port, 12-dust exhaustor, 13-air outlet, 14-safety indicator), 2-housing (21-intake grill, 22-eddy flow impeller, 23-dust separation rotor, 24-dust-collecting plate, 25-pre-flock dust exhaust port, 26-pre-flock air outlet).
Embodiment
Further specify the utility model below in conjunction with drawings and Examples.
Embodiment: the utility model comprises and is provided with suction port 11, the air cleaner assy 1 of dust exhaustor 12 and air outlet 13, also comprise and be provided with intake grill 21, the housing 2 of pre-flock dust exhaust port 25 and pre-flock air outlet 26, all be located at the eddy flow impeller 22 in the housing 2, dust separation rotor 23 and dust-collecting plate 24, described eddy flow impeller 22 is positioned at intake grill 21 belows, described dust separation rotor 23 is positioned at eddy flow impeller 22 belows, described dust-collecting plate 24 is positioned at the outside of dust separation rotor 23, described pre-flock dust exhaust port 25 is positioned at dust-collecting plate 24 belows, and described pre-flock air outlet 26 is communicated with described suction port 11.Also be provided with safety indicator 14 in the described air cleaner assy 1.
During use, air with impurity enters in the housing 2 through intake grill 21, during through eddy flow impeller 22 and dust separation rotor 23, be separated in the dust-collecting plate 24 because the effect of centrifugal inertia force makes in the larger foreign substances from air of particle, then discharge through pre-flock dust exhaust port 25.Enter in the air cleaner assy 1 through pre-flock air outlet 26 and suction port 11 through the air behind the pre-flock, separate because the effect of centrifugal inertia force makes in the less foreign substances from air of particle, then discharge through dust exhaustor 12.Gas through twice filtration enters burning chamber of diesel engine via air outlet 13.When air cleaner assy 1 is stopped up, safety indicator 14 indication that will give the alarm, prompting needs to clean or replacing.
