Description

Higher air filter of practicality

Technical Field

The utility model belongs to the technical field of filtration, concretely relates to higher air filter of practicality.

Background

The turbine type compressor is common air supply equipment in the petrochemical industry, the expensive turbine type compressor must be operated all year round, and the shutdown means the production stoppage; in order to ensure that the turbine compressor does not have faults and operates at high efficiency and the shutdown times and the maintenance workload are reduced to the maximum extent, an air filtering device is arranged at a suction air inlet of the turbine compressor so as to reduce the damage of dust to equipment; in order to ensure the precision and the filtering efficiency of air filtration, two-stage or multi-stage filtering devices are generally arranged, the filtering devices are composed of filter elements with different filtering precisions in a grading way, a fine filtering element is arranged at the innermost layer, and the filter elements with lower filtering precisions are sequentially arranged at the front end of the fine filtering element; the fine filter element generally has a long service life (2-3 years) and a low filtering precision, and plays a role in air pre-filtering, so that the fine filter element is protected, and the service life of the fine filter element is prolonged.

After the air filtering device is arranged, the air filtering device needs to be fixed, usually, the fine filtering element at the innermost layer does not need to be replaced for a long time, and can be fixed by adopting a bolt compression mode or other mechanical compression modes, and other filtering layers at the outer layer of the fine filtering element need to be replaced and maintained frequently, so that some convenient and fast fixing modes are needed; some original fixed modes are if adopt magnetism to adsorb, the thread gluing is connected, and these convenient fixed modes can be because fixed face material changes and can't use, if connection structure when adopting magnetism to adsorb requires the frame must be metal crate, so explore other convenient fixed modes and become must.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model aims at providing an air filter device that practicality is higher.

The utility model adopts the following technical scheme for accomplishing the above purpose:

an air filtering device with higher practicability is provided with two-stage fine filtering; the secondary fine filter is provided with a convex surface protruding outwards; the four convex surfaces are arranged around the circumference, a cavity for placing the primary coarse filter is formed by the four convex surfaces, the primary coarse filter positioned in the cavity is connected to the secondary fine filter through an elastic connecting piece, and the primary coarse filter and the secondary fine filter are elastically connected; the number of the elastic connecting pieces is at least two, and the elastic connecting pieces are symmetrical pairwise; two elastic connecting pieces which are symmetrically arranged are respectively arranged on two symmetrical convex surfaces of the secondary fine filtration.

The elastic connecting piece is a spring; one end of the spring is fixedly connected with the secondary fine filter through a spring base; the other end of the spring is connected with a pressing plate; the pressing plate is elastically pressed on the primary coarse filter to connect the primary coarse filter with the secondary fine filter.

The elastic connecting piece is a rubber strip adhered to the corresponding convex surface; the rubber strip is elastically pressed on the primary coarse filter to connect the primary coarse filter with the secondary fine filter.

The utility model provides a higher air filter of practicality, second grade essence are strained and are connected as an organic wholely at elastic connection spare through the setting with the one-level colating, make one-level colating and second grade essence strain between form elastic connection, have further increased firm in connection between them, and need not inject the frame material of one-level colating, convenient and fast, and the suitability is high.

Detailed Description

The invention is described in connection with the accompanying drawings and the embodiments:

as shown in fig. 1-4 in conjunction with fig. 3, an air filtration device with improved utility has a secondary fine filter 2; the secondary fine filter 2 is provided with a convex surface protruding outwards; the convex surface is a plane; the four convex surfaces are arranged around the circumference, a cavity for placing a primary coarse filter 1 is formed by the four convex surfaces, and the primary coarse filter 1 positioned in the cavity is connected to a secondary fine filter 2 through an elastic connecting piece; the number of the elastic connecting pieces is at least two, and the elastic connecting pieces are symmetrical pairwise; the two elastic connecting pieces which are symmetrically arranged are respectively arranged on the two symmetrical convex surfaces of the secondary fine filtration; in this embodiment, the elastic connecting member is a spring; the spring is provided with a spring base 5 fixed on the convex surface; the spring base 5 is connected with a pressing plate 3 for pressing the primary coarse filtration through a spring 4; the pressing plate 3 is elastically pressed on the first-stage coarse filter; during assembly, two ends of the spring 4 are respectively screwed into the clamping grooves of the pressing plate 3 and the spring base 5, so that the spring 4 is fixed; the pressing plate 3 is moved by compressing the spring 4 at one end, the primary coarse filter 1 is placed in the frame of the secondary fine filter 2 after the movement, the upward movement is carried out, the spring 4 and the pressing plate 3 at the other end are compressed, the other end of the primary coarse filter 1 enters the frame of the secondary fine filter 2, the vertical distance is adjusted, and the pressing plate 3 is pushed by the elasticity of the spring 4 to fix the primary coarse filter 1 in the frame of the secondary fine filter 2.

As shown in fig. 5 and 6, the main structure of this embodiment is the same as that of embodiment 1, in this embodiment, the elastic connecting member is a rubber strip 10 adhered to the corresponding convex surface; the rubber strip 10 is elastically pressed on the first-stage rough filter to connect the first-stage rough filter with the second-stage fine filter.

When the device is installed, the primary coarse filter 1 is pressed into a cavity of the secondary fine filter, rubber strips 3 are bonded on two side wall surfaces corresponding to the secondary fine filter, and the rubber strips 3 generate certain extrusion force after being compressed, so that the primary coarse filter and the secondary fine filter are extruded into a whole.
