The utility model is used for agricultural machinery, engineering machine tool, mining machinery's centrifugal dust collector.
Description
Technical Field
The utility model relates to a centrifugal dust collector for agricultural machinery, engineering machinery, mining machinery.
Background
The existing vehicle air filter adopts a filter element, so that the filter element is blocked by dust in a very short time to cause failure, the filter element must be replaced to continue working, the power of the engine is reduced due to the increase of negative pressure caused by the blockage of the filter element, and more seriously, a small amount of dust enters an air passage through a gap, so that the abrasion loss of the engine is increased, the service life of the engine is reduced, the problem of air filtration in the high-dust environment is solved, and the frequency of replacing the filter element of the air filter is reduced to become an important research and development problem.
Disclosure of Invention
The utility model aims at providing a centrifugal dust collector for agricultural machinery, engineering machinery, mining machinery.
The above purpose is realized by the following technical scheme:
a centrifugal dust collector for agricultural machinery, engineering machine tool, mining machinery, its constitution includes: the cyclone comprises a cyclone cylinder, wherein the side surface of the cyclone cylinder is provided with an air inlet grid, the upper part of the cyclone cylinder is connected with an air collection chamber, the lower end of the air collection chamber is provided with a cyclone baffle ring, the outer side of the cyclone cylinder is provided with an air inlet distribution chamber, the outer side of the air inlet distribution chamber is provided with an air inlet, the lower ends of the cyclone cylinder and the air inlet distribution chamber are connected with an end cover, the middle part of the end cover is provided with an air outlet pipe, and the air outlet pipe penetrates through the cyclone cylinder and the upper end of the cyclone baffle ring to leak into the air collection chamber.
A centrifugal dust collector for agricultural machinery, engineering machine tool, mining machinery, the upper portion of outlet duct be equipped with bowl type cap, bowl type cap opening downwards, bowl type cap be in whirlwind keep off the top of ring, bowl type cap with whirlwind keep off the interannular distance and be 1-2 times the outlet duct logical warp, the end cover on be equipped with out the dirt mouth, play dirt mouth on be equipped with the dust cup, go out the dirt mouth with end cover airtight connection, go out the dirt mouth dust cup be threaded connection.
The utility model has the advantages that:
1. the utility model discloses an in the structure a cyclone have the angle slope and follow the direction grid that admits air that the circumferencial direction distributes for by the indoor entering of distribution of admitting air the dirty air behind the grid of a cyclone form rotatory air current, because dust particle density is far greater than the air molecule, therefore under centrifugal force effect the dust is separated cyclone lateral wall on fall down, and clean air then by cyclone keep off the middle part air flue of ring and get into the collection chamber, via at last the outlet duct get into the air cleaner of engine, this process can be that the dirty air of high dust content is purified, the dust content of gas outlet can reduce to being less than 300 micrograms per cubic meter, has improved the cleanliness factor of engine intake air, and then the protection engine can not early damage the inefficacy.
The utility model discloses dust separation is carried out to the physical property of dust density and clean air mass density difference based on suspension, does not need the supplementary consumables of disengaging process if: the paper filter element, the filter screen or the water and other media have simple structure and reliable operation, are additionally arranged as the front stage of the air filter of the engine, can reduce the consumption of the air filter once and for all, improve the service life of the engine and reduce the total cost in the service lives of agricultural machinery, engineering machinery and mining machinery.
The utility model discloses a dust cup collects the dust after the separation, is favorable to centralized processing, can not cause secondary pollution.
The utility model discloses an air inlet is admitted air for the side direction, is favorable to the site selection installation on the vehicle.
