Abstract
The invention discloses an air filtering system of a forklift, and belongs to the technical field of air filtration of automobiles. The air filtering system of the forklift comprises a paper air filter and an oil-bath-type air filter, wherein a gas outlet of the paper air filter is connected with a gas inlet of a forklift diesel engine; the oil-bath-type air filter is internally provided with a metal wire filter layer and an oil bath disc sequentially from top to bottom; the metal wire filter layer is arranged above the oil level of the oil bath disc; both a gas outlet and a gas inlet of the oil-bath-type air filter are formed above the oil-bath-type air filter; the gas inlet of the oil-bath-type air filter is connected with the oil bath disc by an oil bath disc gas ventilation pipe, and the oil bath disc gas ventilation pipe extends to the position below the oil level of the oil bath disc; the gas outlet of the oil-bath-type air filter extends to the position above the metal wire filter layer by a metal wire filter layer gas ventilation pipe; meanwhile, the gas outlet of the oil-bath-type air filter is connected with the gas inlet of the paper air filter through a connecting pipe. The air filtering system of the forklift, which is disclosed by the invention, can filter fine dust, thus reducing the abrasion to the diesel engine, and lowering the maintaining expense.
Description
Technical field
The present invention relates to a kind of fork truck air filtering system, belong to automotive air filter technical field.
Background technology
Existing fork truck air filtering system, as shown in Figure 1, mainly made by papery air filter, air is directly passed into diesel engine of forklift truck inside after papery air filter is filtered, but for imperceptible powder, papery air filter can not well be filtered, and therefore has imperceptible powder to enter diesel engine by diesel engine of forklift truck papery filter, cause wear of diesel engines serious, increased the cost of repairs.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the invention provides a kind of fork truck air filtering system that can filter minute dust.
For achieving the above object, the technical solution used in the present invention is:
A kind of fork truck air filtering system, comprise papery air filter, the gas outlet of described papery air filter is connected with diesel engine of forklift truck air inlet, also comprise oil bath air filter, described oil bath air filter inside is disposed with wire filtering layer and oil bath dish from top to bottom, and described wire filtering layer is arranged on the pasta of oil bath dish; The gas outlet of described oil bath air filter and air inlet are all arranged at oil bath air filter top, be connected, and described oil bath dish breather pipe extend under the pasta of oil bath dish between described air inlet and oil bath dish by oil bath dish breather pipe; And the gas outlet of described oil bath air filter is deep into the top of wire filtering layer by wire filtering layer breather pipe, and the distance between described wire filtering layer breather pipe and oil bath air filter end face is not 0, the gas outlet of described oil bath air filter is connected with the air inlet of papery air filter by tube connector simultaneously.
Preferred: the filter screen diameter of described wire filtering layer reduces from down to up successively.
Preferred: the distance between described wire filtering layer breather pipe and oil bath air filter end face is that wire filtering layer is to 1/3rd of the distance between oil bath air filter end face.
Preferred: described oil bath dish breather pipe extend into distance under the pasta of oil bath dish be oil bath dish fuel head 2/3rds.
A kind of fork truck air filtering system provided by the invention, compared to existing technology, has following beneficial effect:.
Owing to being provided with oil bath air filter, described oil bath air filter inside is disposed with wire filtering layer and oil bath dish from top to bottom, and the air that contains impurity, by food tray, makes the impurity of air contact with oil product, hands over and makes it to adhere to oil film, reaches air single filter.Air, by wire filtering layer, sticks in wire the impurity being wrapped up by oil film subsequently, reaches air cascade filtration.Filter (paper filter) through for the third time again, enter air substantially free of impurities or minute dust in diesel engine, therefore the present invention can filter minute dust, has therefore reduced the wearing and tearing of diesel engine, reduces the cost of repairs.Thereby reach the object of protection diesel engine of forklift truck and minimizing maintenance cost.

A kind of fork truck air filtering system, as shown in Figure 2, comprise papery air filter, the gas outlet of described papery air filter is connected with diesel engine of forklift truck air inlet, also comprise oil bath air filter, described oil bath air filter inside is disposed with wire filtering layer and oil bath dish from top to bottom, and described wire filtering layer is arranged on the pasta of oil bath dish; The gas outlet of described oil bath air filter and air inlet are all arranged at oil bath air filter top, be connected, and described oil bath dish breather pipe extend under the pasta of oil bath dish between described air inlet and oil bath dish by oil bath dish breather pipe; And the gas outlet of described oil bath air filter is deep into the top of wire filtering layer by wire filtering layer breather pipe, and the distance between described wire filtering layer breather pipe and oil bath air filter end face is not 0, the gas outlet of described oil bath air filter is connected with the air inlet of papery air filter by tube connector simultaneously.
The filter screen diameter of described wire filtering layer reduces from down to up successively.
Distance between described wire filtering layer breather pipe and oil bath air filter end face is that wire filtering layer is to 1/3rd of the distance between oil bath air filter end face.
Described oil bath dish breather pipe extend into distance under the pasta of oil bath dish be oil bath dish fuel head 2/3rds.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
