Abstract
The utility model discloses an improved internal structure for a gas filter. The internal structure comprises an improved sealing device and an improved internal filtering bracket structure of the gas filter. The improved internal structure is mainly characterized in that a sealing groove is formed in a sealing surface between a main body and a cup cover and is used for accommodating a sealing ring 1; and the sealing ring is a hard deformed sealing gasket made of rubber material. A gas filter is important equipment of a gas combustion system; in the process that gas is conveyed and distributed in the system, the gas filter is mounted in an internal gas pipeline or a compressed air pipeline for removing dust, scrap, iron rust, other solid concomitants and pollutants in the gas and other impurities, and thus normal work of rear gas equipment such as gas valve parts, flow meters and pressure gages is ensured and the gas equipment is protected from being damaged.
Description
Technical field
The utility model relates to a kind of sealing device and structure stand, relates to the inner accessory of a kind of gas filter in particular, is mainly used in the combustion apparatus field.
Background technology
At present; Air filter has the different standards that manufactures and designs according to model, connection specification, the installation dimension of burner with the pressure-bearing scope; The utility model technology is mainly improved to be that flange form connects the aluminium air filter, and it mainly is made up of aluminium shell, seal, filtration cotton core and bowl cover.Before improving, the zero type circle that seal uses rubber to process, this zero type circle is the sealing ring of circle shape, and the groove that is processed with special settings in main body and bowl cover seals at is used to place zero type circle, and zero type circle reaches the purpose of sealing during sealing because of crimp.But this Sealing Technology is very high to requirement on machining accuracy, in the production in the past, does not usually cause product defective because of sealing reaches standard.
In air filter, what play a role in filtering is to filter cotton core, because of there is stainless supporting network inside; Can form a C cambered surface at the air inlet place; This cambered surface can make full use of the filter area of filter cotton, but in the past the production, and of no use have certain thickness support stainless steel supporting network and main body inner wall are separated; Make filter cotton easily with main body inner wall contact, reduced the filter area of filter greatly and hindered the gas communication property of air inlet.
Summary of the invention
The purpose of the utility model is to above-mentioned existing problems, improves a kind of sealing device and designs a kind of bracing frame, guarantees the sealing and the filter effect of air filter.
For achieving the above object, the technical scheme of the utility model is: the cirrhosis shape seal washer that sealing device adopts elastomeric material to process, on the contact-making surface of main body and bowl cover; Process a seal groove; During sealing, put seal washer into respective slot, cover bowl cover and tighten the screw that covers.Bracing frame is a kind of C shape bracing frame that adopts white plastic to process.The project organization of C shape meets the structure of cavity inner wall and guides the placement of filter cotton, and the size of bracing frame changes according to the air filter model of different model.
The beneficial effect of the utility model is that cirrhosis shape seal washer has high leakproofness, relies on outside screw tightening to reach sealing function, has reduced the dependence to machining accuracy, improves the seal degree and the service life of filter.C shape bracing frame is separated out the space between filtration cotton core and main body, utilized the filter area of filter cotton more fully, reduces the combustion gas circulating resistance, and easy for installation, easy to maintenance.
Description of drawings
Fig. 1 is the vertical view of the utility model place air filter main body.
Fig. 2 is the side view of the utility model place air filter.
In the accompanying drawing, the 1st, seal washer, the 2nd, filter cotton core, the 3rd, white bracing frame, the 4th, screw hole, the 5th, bowl cover, the 6th, combustion gas pressure measurement detection tabs.
The specific embodiment
With embodiment the utility model is further described below.
Air filter mainly is divided into two parts: main body and bowl cover.Main body is provided with air inlet and is connected gas pipeline with the gas outlet, and middle cavity is used for placing filtration cotton core 2 and white bracing frame 3.Main seal washer 1 sealing of adopting in the utility model between main body and the bowl cover 5, outside then tighten the screws, screw hole 4 can be set different hole counts according to the size of air filter.Main body accent place is provided with the respective slot of placing seal washer 1, then places white bracing frame 3 at the bottom of the chamber, and white bracing frame 3 will filter between cotton core 2 and the cavity and be separated out the space.Filtering cotton core 2 is to be made up of polypropylene non-woven fabric, hole diameter≤50 μ m, and there is stainless supporting network inside, and nonwoven is bent to form a C cambered surface, is supported on inside cavity.Wherein, bowl cover 5 places also have the corresponding draw-in groove can be parallel with white bracing frame 3, play fixing effect.Whether combustion gas pressure measurement detection tabs 6 is used to connect the gas pressure difference detector, detect air filter and under normal air pressure, work.
The above specific embodiment has been explained the handling characteristics of the utility model, and its purpose is to let the personage who is familiar with this field can understand content of the utility model and enforcement according to this, can not limit the protection domain of the utility model with this.All within the spirit and principle of the utility model, any modification of being made, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
Claims (2)
1. improved air filter internal structure; Said air filter comprises main body and bowl cover; It improves design feature and is: at the sealing surface place of main body and bowl cover; The design sealed groove is used to place seal washer (1), and seal washer (1) is the cirrhosis shape seal washer that adopts elastomeric material to process.
2. a kind of improved air filter internal structure according to claim 1 is characterized in that: the C shape bracing frame (3) in a white of main body cavity bottom increase is separated out a space between filtration cotton core (2) and cavity.
