Abstract

The utility model provides a high efficient air filter whose filtering core is matched and connected with the inner part of a frame (1) through a connecting component composed of a connecting frame, a press frame and a screw to compose an air filter with a movable filtering core, and an inner and an outer supporting frames supporting the filtering core and connected with the filtering core are respectively arranged on the connecting frame and the press frame. The utility model has novel structure and simple use and maintenance, and the high efficient air filter can be used for air purification engineering, being a novel high efficient air filter.

Description

High efficiency particle air filter

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

Mostly common high efficiency particle air filter is to adopt the fixedly filter-core type air cleaner that the direct fixture of corrugated filtering element (cartridge) is formed in the framework of filter.But in use, when filtering element (cartridge) reaches operating limit, must carry out the replacing of whole filter, easily cause waste, the cost of use height, assembling is safeguarded numerous and diverse, uses inconvenience.Especially adopt no dividing plate filtering element (cartridge), amount to not have between filtering surface and support that its bulk strength is low, resistance big, the application cycle is shorter.

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

The utility model is achieved in that filtering element (cartridge) is connected by the connector of being made up of connection frame, press box and screw and is combined into the core type air cleaner alive of energy dismounting and change filtering element (cartridge) in the framework of filter.

Be to improve the intensity and the filter efficiency of filtering element (cartridge), also can be on the connection frame load inner support support the end knuckle of filtering element (cartridge), the load support arm supports the top knuckle of filtering element (cartridge) on press box, make at the bottom of the corrugated filter membrane of filtering element (cartridge) around inner support, top around support arm back and forth turn back tighten fixing.

Owing to adopted the active filtering core structure in the above-mentioned solution, disassembling, assembling and replacing filtering element (cartridge) very easily, use and maintenance easy, especially filtering element (cartridge) is adopted inside and outside stent support to compress, make that the whole intensity of filtering element (cartridge) is strengthened, filtration resistance power reduces, improved life cycle and filter efficiency.It can be widely used in the air purification engineering of industries such as machinery, electronics, metallurgy, chemical industry, medical treatment, 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.

With reference to accompanying drawing 1, Fig. 2 and Fig. 3, filtering element (cartridge) of the present utility model (2) is connected by the coupling components of being made up of connection frame (7), press box (4) and screw (3) and is combined into the active filtering core air cleaner in framework (1).The connection frame (7) of coupling components is fixedly connected on the body inwall of filter framework (1), and connection edge and sealing gasket thereof are fastening by screw (3) connection around folder between connection frame (7) and press box (4) connection even filtering element (cartridge) (2).

The utility model is connected with support arm (5) (seeing Fig. 6, Fig. 7), the top knuckle of support arm (5) support and connection filtering element (cartridge) (2) on press box (4).Go up connection inner support (6) (seeing Fig. 4, Fig. 5), the bottom knuckle of inner support (6) support and connection filtering element (cartridge) (2) at connection frame (7).

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