Abstract

The utility model relates to a paper plate-type air fine filter for the internal combustion locomotive used for filtering the intake air of the internal combustion locomotive, which is composed of a case and a filter core arranged in the case. The case is composed of a case cover and a case body which are hinged by a hinge. The case cover and the case body are frame hollow structure. The middle of the frame at the bottom part of the case body is inlaid with a steel wire net. The frames at both sides at the upper part of the case cover are provided with a spring clip for installing and clamping. The lower end of the case body is provided with a handle. Corresponding locking openings arranged on the case cover and the case body. The filter core is folded by fluted filter paper, and is sealed and arranged in the case body. The utility model has the advantages of a high filtering efficiency, light weight, low cost, and low energy consumption, and the filter core is replaced.

Description

Paper plate-shaped air fine filter for internal combustion locomotive

The utility model relates to a kind of air filter, is specially adapted to the filtering of internal combustion locomotive inlet air.

The air fine cleaner of China railways internal combustion locomotive employing at present mainly is the steel plate net-type filter, its structure is that 16 layers of Mild Steel Expanded Sheets are stacked, reach wet type filtering effect with the immersion oil mode, just the Mild Steel Expanded Sheets filter efficiency of immersion oil is about 93%, in use for some time, especially in wind sandy ground district, its filter efficiency sharply descends, and can not satisfy the purpose of fine filtering.Weight behind this in addition filter cleaner immersion oil is more than 15 kilograms, and intensity of workers is big, and filter efficiency is low again, is not subjected to on-the-spot the welcome.A handful of internal combustion locomotive is to install to introduce the cartridge type air-strainer that GE company produces, and its volume is big, resistance is high, recondition expense is big, power consumption, and high price is expensive.

The purpose of this utility model is the shortcoming that overcomes existing internal combustion locomotive air-strainer, and a kind of efficient height, in light weight, cost is low, power consumption is little papery plate type air fine cleaner are provided.

The technical solution of the utility model is achieved in that a kind of internal combustion locomotive papery plate type air fine cleaner, its special way is that it is made up of a box and the filter core that is contained in the box, box is to be formed by hinge is hinged by lid and box body, lid and box body are the framework hollow structure, stud with steel wire in the middle of the box body lower frame, both sides, lid top frame is equipped with for the spring clamp that chucking usefulness is installed, and handle is equipped with in the box body lower end, and corresponding fore shaft is housed on lid and box body; Filter core adopts the corrugation filter paper to fold and forms, and sealing is installed in the box body.

The utility model advantage compared with prior art is the filter efficiency height, and in light weight, resistance is little, and low price specifically relatively sees table:

Type	Filter efficiency (%)	Weight (kg)	Resistance (pa) just	Life-span (year)	Price (unit)
						Mild Steel Expanded Sheets	93－70	15	90	Return multiple use	1800
Cartridge type	98	10	300	15	3600
						The utility model	98	5	200	0.8	1600

Now describe the utility model most preferred embodiment in conjunction with the accompanying drawings in detail

Fig. 1 is internal combustion locomotive papery plate type air fine cleaner structural representation;

Fig. 2 is Figure 1A-A sectional drawing.

Among the figure: the 1-hinge; The 2-lid; The 3-filter core; The 4-spring clamp; The 5-fore shaft; The 6-handle; The 7-steel wire; The 8-box body.

A kind of internal combustion locomotive with papery plate type air fine cleaner as shown in Figure 1, it is made up of a box 2,8 and the papery filter core 3 that is contained in the box, box is by hinge 1 hinged forming by lid 2 and box body 8, lid 2 and box body 8 are the framework hollow structure, stud with steel wire 7 in the middle of box body 8 lower frames, both sides, lid 2 top frame is equipped with for the spring clamp 4 that chucking usefulness is installed, and handle 6 is equipped with in box body 8 lower ends, on lid 2 and box body 82 corresponding fore shafts 5 is housed respectively; Filter core 3 adopts that the corrugation filter papers are folding to form sealing and be installed in the box body 8, and to the technical requirements of filter core 3 be: resistance is below the △ P=300Pa, and anti-broken intensity is 8kPa/m ²Efficient is not less than 98%, papery plate type air fine cleaner device periodic replacement filter core 3, and framework can be reused, more from the import air channel, extract fine cleaner by the handle on the fine cleaner 6 out during renew cartridge 3, open lock-joint 5, open lid 2 filter core of using 3 is taken out from box body 8, new filter core 3 is packed in the box body 8, build lid 2, lock fore shaft 5, fine cleaner is reloaded in the air channel, be clamped in the air channel by spring clamp 4.

Claims

1, a kind of internal combustion locomotive papery plate type air fine cleaner, it is characterized in that it is made up of a box and the filter core that is contained in the box, box is to be formed by hinge is hinged by lid and box body, lid and box body are the framework hollow structure, stud with steel wire in the middle of the box body lower frame, both sides, lid top frame is equipped with for the spring clamp that chucking usefulness is installed, and handle is equipped with in the box body lower end, and corresponding fore shaft is housed on lid and box body.

2, fine cleaner according to claim 1 is characterized in that filter core adopts the corrugation filter paper to fold and forms, and sealing is installed in the box body.
