CN2227516Y - High efficiency air filter with active filtering core - Google Patents

Abstract

The utility model discloses a high efficiency air filter with an active filtering core. The filtering core of the filter is matched and connected with the inner part of a frame body through a connecting piece composed of a holding frame, a press frame and screws, and a supporting frame is arranged in the top bending angle of the filtering core, or the folding unit of the filtering core is divided into a plurality of separated filtering chambers through a uniform flow spacing section. The utility model has novel structure, convenient disassembling and replacement to the filtering core, convenient use and maintenance, long service life and high filtering efficiency.

Description

The active filtering core high efficiency particle air filter

The utility model relates to a kind of gas filtration apparatus, is a kind of high efficiency particle air filter that is applicable to air purification engineering particularly.

The used high efficiency particle air filter of existing air purification engineering mostly is the fixedly filter-core type air cleaner of being made up of folding corrugated element fixing device of filter in the filter framework, and filtering element (cartridge) is amounted to, and space of planes is excessive not to have supporter again, its bulk strength is low, the resistance height, and life cycle is shorter.Especially filtering element (cartridge) is directly fixed on the filter body, must change whole filter when filtering element (cartridge) reaches operating limit, and cost of use height, installation and maintenance are numerous and diverse, make troubles to use.

The purpose of this utility model provides a kind of improved high efficiency particle air filter, makes its novel structure, bulk strength height, and the application cycle is long, and the assembling easy maintenance is easy to use.

For achieving the above object, the solution that adopts of the utility model is: with filtering element (cartridge) by the connector of forming by carriage, press box, screw be connected in the framework of filter, be combined into detachable replacing filtering element (cartridge) core type air cleaner alive.

And in the knuckle of the top of filtering element (cartridge), install bracing frame, perhaps adopt the current-sharing compartment to be separated into a plurality of filter chambers the unit of amounting to of filtering element (cartridge) again, to strengthen the intensity of filtering element (cartridge).

Owing to adopted the active filtering core structure in the above-mentioned solution, disassembling, assembling and replacing filtering element (cartridge) easily, use and maintenance easy maintenance.Especially having installed bracing frame additional and adopted the current-sharing compartment in filtering element (cartridge), made that the filtering element (cartridge) bulk strength improves, resistance reduces, both improved service life and also improved filter efficiency, is a kind of novel high efficiency particle air filter.

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is a front view of the present utility model.

Fig. 2 is that partial sectional view is looked on the left side of Fig. 1.

Fig. 3 is the amplification assumption diagram of a part among Fig. 2.

Fig. 4 is that the utility model is the front view of filtering element (cartridge) among Fig. 1 (2).

Fig. 5 is the vertical view of Fig. 4.

Fig. 6 is the profile of filtering element (cartridge) among Fig. 5 (2) along the A-A line.

Fig. 7 is that the utility model is the front view of bracing frame among Fig. 1 (3).

As accompanying drawing 1, Fig. 2, shown in Figure 3, filtering element (cartridge) of the present utility model (2) is connected by the coupling components of being made up of carriage (4), press box (6) and screw (5) and is combined into the active filtering core air cleaner in framework (1).The carriage of this filter coupling components (4) is fixedly connected on the body inwall of framework (1), connect press box (6) above the carriage (4), carriage (4) and folder between press box (6) is connected connect filtering element (cartridge) (2) around connection along and sealing gasket by screw (5) carriage (4), filtering element (cartridge) (2) are connected with press box (6) again and are tightened to one.

The utility model also is connected with as shown in Figure 7 bracing frame (3), the top knuckle (see figure 2) of bracing frame (3) support and connection filtering element (cartridge) (2) by grab (7) on carriage (4).

With reference to accompanying drawing 4, Fig. 5, Fig. 6, the unit of amounting in the utility model filtering element (cartridge) (2) is separated into 2-6 branch filter chamber by current-sharing compartment (8).

In order to ensure the filter efficient low-resistance, be convenient to the cleaning and the repeated use of filtering element (cartridge), filtering element (cartridge) (2) adopts the high-strength chemical fibre filter material of low-resistance to make.

Claims (3)

1, a kind of high efficiency particle air filter of forming by filtering element (cartridge) and framework, the filtering element (cartridge) (2) that it is characterized in that this filter is connected in framework (1) by the coupling components of being made up of carriage (4), press box (6) and screw (5), carriage (4) is fixedly connected on the body inwall of framework (1), carriage (4) and folder between press box (6) is connected connect filtering element (cartridge) (2) around connection along and sealing gasket connect fastening by screw (5).

2, filter according to claim 1 is characterized in that carriage (4) upward is connected with bracing frame (3) by grab (7), the top knuckle of bracing frame (3) support and connection filtering element (cartridge) (2).

3, filter according to claim 1 and 2 is characterized in that the unit of amounting in the filtering element (cartridge) (2) is separated into 2-6 branch filter chamber again by current-sharing compartment (8).
