Description
Technical field
The utility model relates to a kind of air filtration unit, specially refers to the air filtration unit in the air filtration system on a kind of internal combustion locomotive.
Background technique
For a long time, the cylinder sleeve of engine wearing and tearing are puzzlement diesel locomotives in China user's serious problems always; Particularly in recent years along with the deterioration of physical environment, this problem reflects particularly outstandingly.The main cause that causes this problem is exactly that the air filtration unit of internal combustion locomotive is poorly sealed, has entered the unholiness air that contains dust equivalents dirt in the motor.For addressing this problem, the filter that has at present adopted many swirl tube air cleaners and papery filter cleaner to combine in the dust storm area carries out the air filtering of internal combustion locomotive, but have the following disadvantages on its structure, the one, air filtration unit and locomotive car body are the welding assembling, caused distortion can cause poorly sealedly during welding, and this welding manner has also brought inconvenience for maintenance; The 2nd, air filtration unit designs at concrete vehicle, and for overall structure and locomotive car body weld assembling, the ability of versatility, interchangeability and standardized production is relatively poor, when the expansion of needs function has difficulties when improving air purity; The 3rd, many swirl tube air cleaners and papery filter cleaner are the non-tight assembling, and the air of filtering does not easily enter motor by poorly sealed air flue; The 4th, many swirl tube air cleaners and suction port and dust exhaust port can not closely cooperate, and cause entering of unholiness air on the one hand, influence the exhausting effect of dust exhaust port on the other hand, cause dust discharge ineffective, and then reduce the air purity of air outlet; The 5th, the top of papery filter cleaner with exist cooperating of air outlet stressed irregularly, cause the poorly sealed problem of air outlet.
The model utility content
The purpose of this utility model is: at the above-mentioned deficiency of existing air filtration unit, a kind of unit air filter system is provided, improve the ability of sealing, versatility, interchangeability and the standardized production of air filtration unit, and then the cleanliness of raising air outlet air, reduce the wearing and tearing of locomotive engine cylinder sleeve.
The utility model is achieved through the following technical solutions above-mentioned purpose:
Unit air filter system, comprise many swirl tube air cleaners, papery filter cleaner, many swirl tube air cleaners tap into gas port, the papery filter cleaner is positioned on the pallet on the support on many swirl tube air cleaners top, the top of papery filter cleaner picks out gas port, many swirl tube air cleaners and papery filter cleaner place in the airtight casing, form cellular structure, and a plurality of installation screws are arranged on the casing.
Described unit air filter system, the bottom of papery filter cleaner have locating stud and puller mechanism independently.
The puller mechanism of papery filter cleaner adopts screw spiral to hold out against mode, and fastening screw passes on the pallet that support withstands on the papery filter cleaner, and a nut is respectively arranged up and down, and locating stud is fixed on the support, withstands on the pallet.
Front on many swirl tube air cleaners has side pressure mechanism up and down, and press mechanism is arranged above.
Side pressure mechanism is the screw spiral tension mode, and box back surface is fixed with distance and corresponding two screw rods of many swirl tube air cleaners width, passes the front that a pressing plate is pressed in many eddy flows tubular type filter cleaner on the screw rod, respectively is rotary with a nut on each screw rod.
Press mechanism is a screw spiral roof pressure mode, and two nuts are fixed on the support, is rotary with a screw rod that can be rotated down the many swirl tube air cleaners of roof pressure on each nut.
Airtight casing has dismountable chamber door, and sealing joint strip is arranged on the chamber door.
Installation screw on the casing can change the installation screw rod into.
The beneficial effects of the utility model are that employing places many swirl tube air cleaners and papery filter cleaner in the airtight casing, has improved sealing effectively, has reduced unclean air just enters motor without filtering possibility; Be enclosed within the cellular structure of casing, help in filtering effect deficiency, carrying out the function expansion, or improve versatility and the interchangeability of air filtration unit between the various kinds of vehicles vehicle, and the convenience of overhauling; Screw adopt to be installed on the casing to be assembled, solved in the past owing to welding the poorly sealed problem that the distortion that causes causes with locomotive; Papery filter cleaner bottom has added locating stud and puller mechanism, can keep its top stressed evenly when upwards holding out against the papery filter cleaner, avoids between papery cleaner top section and the air outlet because of the stressed irregular poorly sealed problem that causes; The press mechanism on many swirl tube air cleaners top can compress itself and dust exhaust port, improve the exhausting effect of dust exhaust port, and then avoided influencing once again the problem of air purity because of the bad dust that causes of its exhausting effect, side pressure mechanism compresses many swirl tube air cleaners and air outlet, has avoided unclean air to enter outside suction port effectively.In sum, visible the utility model has improved the ability of sealing, versatility, interchangeability and the standardized production of air filtration unit, and then has improved the cleanliness of air outlet air by adopting above-mentioned structure, reduces the wearing and tearing of locomotive engine cylinder sleeve.
In the area of dust storm especially severe, from the working life of cylinder sleeve, adopt the locomotive of original air filtration unit generally can only move about 6～80,000 kilometers, and the locomotive of this unit air filter system on probation has now moved 200,000 kilometers.
