Abstract
The strengthened cyclone single-barrel straight-through type air filter for a desert, which successively consists of a blind window type tangential air inlet device (1), an air inlet cyclone device (2), an air/dust separating cavity (3), an automatic dust discharge system (4), a main filter (5) and a safe filter element (6). The strengthened cyclone single-barrel straight-through type air filter is structurally characterized in that air flowing in an engine flows through the blind window type tangential air inlet device (a preliminary cyclone device) at first to form cyclone, the rotation strength of airflow discharged from the main cyclone device is greatly strengthened via the air inlet cyclone device (the main cyclone device), and after the rotating airflow enters the air/dust separating cavity, dust in the airflow is subsided onto the wall of the separating cavity under effects of centrifugal force, is blown to a dust collecting cavity by automatic dust blowing blades, and then is discharged from the filter by a dust discharging valve via a dust discharging tube. After being precisely filtered by the main filter, air separated in a strengthened centrifuging manner flows through the safe filter element, and finally clean airflow is led to the engine from an air outlet tube of the main filter.
Description
Technical field
The air-strainer that heavy-duty car that the present invention relates to use in a kind of desert, mine, building site and all the how grey environment and engineering machinery are used.
Background technique
The heavy-duty car air-strainer of work under desert and all how grey environment, at first prerequisite condition are that pre-flock efficient is high.General main engine factory assert, the pre-flock efficient of the empty filter in desert must reach the highest a kind of of the middle pre-flock efficiency index of China automobile industry standard QC/T770-2006 " automobile is with dry-type air cleaner assembly technical specifications ", and pre-flock efficient must be greater than 91%.Second condition that should possess is the function that prefilter must possess automatic removing dust.The 3rd prerequisite condition is filter assembly band safety filter core, and its original resistance should not surpass 3.5kPa.
The existing desert air-strainer of current China mostly adopts the reverse type cyclone tube, mostly adopts multitube combined type prefilter.This prefilter merits and demerits all clearly, advantage is that pre-flock efficient is high, can reach 91%, even higher, but its shortcoming is also very obvious:
(1) resistance is big, and air inflow is reduced, and causes engine power to reduce;
(2) complex structure, volume is big, cost is high;
(3) ash discharge difficulty, can not realize thorough automatic removing dust, maintenance is inconvenient.
Summary of the invention
The objective of the invention is to overcome the deficiency of existing technology, and a kind of rotational flow strengthening monotubular straight-through type desert air-strainer is provided.It is high that it not only has pre-flock efficient, the performance advantage that intake resistance is little, and prefilter to realize that the function of thorough automatic removing dust also has a volume little, characteristic of simple structure.Its concrete technological scheme is: the empty filter in rotational flow strengthening monotubular straight-through type desert, form by louvre type tangential admission device, air inlet cyclone separator, gas ash disengagement chamber and main filter and safe filter core successively.
Described louvre type tangential admission device, its tangential admission mouth and axis are 30 ° of angles, and the air that the tangential is got into is the down state of eddy flow.Central authorities at the tangential admission device are provided with the water conservancy diversion cylinder.
Described air inlet cyclone separator is that the difference of rated flow can be provided with 6 to 12 leaf guide vanes, desirable 25 ° to 40 ° of guide vane established angle according to the difference of coupling engine power; Overlapping angle between the adjacent blades should be not less than 30 °.
Described gas/grey disengagement chamber is to adopt the monotubular straight-through structure, and the prefilter steam outlet pipe that is arranged in gas/grey disengagement chamber center is the suction tude of main filter.
Described automatic ash discharge system is made up of fan apparatus for ash, cinder catcher, ash releasing tube, Ash valves, and its middle fan apparatus for ash has innovative design most, and the angular velocity of rotation that is based on the cyclone tube central gas stream designs greater than the principle of the angular velocity of rotation of cylindrical air-flow.Swirling eddy with the cyclone tube center drives the grey blade assembly rotation of fan, makes Automatic fan ash device fan the air-flow rotating speed height of the rotating ratio of grey blade near gas/grey disengagement chamber periphery, makes the grey blade of fan be able to the fan ash to cinder catcher.The fan ash blade of fan apparatus for ash through connecting rod with rotatingshaft be connected, the driven vane that 4 leaves are square forms between connecting rod and the rotatingshaft with injection molding way.Rotatingshaft is connected with stationary axle with rolling bearing, and stationary axle is fixed on the central draft tube of air inlet cyclone separator with fixing bolt.
Through behind the pre-flock, the air-flow of cleaning promptly through the suction tude of main filter, gets into main filter, and again through safe filter core, the air-flow of cleaning is guided motor into from the steam outlet pipe of main filter at last after the smart filter of the main filter core of process.
It is high that the present invention not only has pre-flock efficient, the premium properties that intake resistance is little, and can realize the thorough function of dust discharge automatically, also have characteristics such as volume is little, simple in structure, easy maintenance.
