Abstract
The utility model relates to a fluid filter chiefly comprising a filtering element and a housing, wherein the filtering element is formed by the method that a corrugated sheet filtering medium and a flat sheet filtering medium present an alternative laminated structure with a Chinese character 'zhi' shape. The corrugated sheet filtering medium has the shape that both ends are provided with flat-straight edges and the middle is provided with a wave-shaped sheet, wherein the flat-straight edges of the corrugated sheet filtering medium are lined up with the same-width single edge of the flat sheet filtering medium to be welded together to present a seal with a Chinese character 'zhi' shape; both ends of the Chinese character 'zhi'-shaped are provided with a fluid inlet end and a fluid outlet end in order to form a filtering path for the inlet/outlet of the fluid. The flat-straight edges on both ends of the corrugated sheet filtering medium can be positioned in the center position of the wave shape, and also one end can be positioned on the upper part of wave shape, and the other end is positioned on the lower part of the wave shape. Sealing gums are coated between both sides of the filtering element and the side surface in the housing to prevent the leakage of the fluid containing the dust. The fluid filter of the utility model is especially suitable for filtering the carbon particles of the exhaust gas of diesel engines and simultaneously is suitable for filtering other kinds of fluids.
Description
Technical field
The utility model belongs to the filtering flow field, more specifically to a kind of fluid filter.
Background technique
In the industrial field of current each class, be the gas solid separation of finishing fluid, liquid-solid separation or gas-liquid separation, extensively adopt leaf filter, bag filter, tubular filter or pleat page filter.The filter of this many kind has different characteristics separately, therefore is suitable for different types of filtering flow.
The diesel engine emissions tail gas discharged that is used for automobile, engineering machinery, municipal machinery, farm machinery and boats and ships contains a large amount of carbon microspheres, causes serious environmental to pollute.And the fluid filter that is used for this respect at present is not ideal enough, as the porcelain filter gas permeability is not high, fluid-pressure drop is big, pollutant holding capability is little; Filter area in the metal fiber filter per unit volume causes shortcomings such as volume is big, filter area is little than little.
The model utility content
The utility model provides a kind of fluid filter, is particularly suitable for the diesel motor exhaust carbon microsphere and filters, and also is fit to the filtering flow of other kind simultaneously.
Fluid filter of the present utility model mainly comprises filter element and shell (5), filter element is " it " font alternate laminated structure by corrugated sheet filter medium (1) and flat panel filter medium (2) and constitutes, the shape of corrugated sheet filter medium (1) is that two ends are flat side, the centre is the waveform plate, the flat side at its two ends can be in corrugated neutral position, shown in Fig. 2 B; Also can be in corrugated top by an end, an other end is in corrugated bottom, shown in Fig. 2 A.The flat side of corrugated sheet filter medium (1) is " it " font and seals with aliging with the flat panel filter medium (2) of width monolateral to weld together, " it " font two ends are fluid inlet end (3) and fluid outlet (4), to form the filtration channel of fluid turnover, shown in Figure 1A and Figure 1B.Total number of plies of corrugated sheet filter medium (1) and dull and stereotyped filter medium (2) is decided according to the required area of fluid filter; The value of stack height H is between 2～10mm, and the corrugation pitch L of corrugated sheet filter medium (1) decide according to the filter media material that adopted and fluid filter length, is worth between 4～20mm.Fig. 3 is by multilayer corrugated sheet filter medium (1) and dull and stereotyped filter medium (2) the 3D view of one group of filter element constituting of stack alternately, and filter element is compressed up and down in the back insertion shell (5), as shown in Figure 4 and Figure 5.Scribble sealer between the both sides of filter element and shell (5) inner side surface, with the leakage of control dust-laden fluid.The sealer kind that is adopted can be decided according to the operating conditions of fluid filter.This fluid filter profile has circle, ellipse and rectangle etc.
Because the uniqueness of structure makes to the utlity model has following advantage: the filter area ratio in the per unit volume is up to 0.6～0.8m
2/ L, filter element compressive strength height, anti-current body impact is good, fluid-pressure drop is little, pollutant holding capability is big etc.
