Abstract
The utility model discloses a kind of still air filter.Filter housings, filtering area, rain cap; Described filter housings side is provided with rain cap; Filtering area is provided with in described filter housings; Grade one filter, secondary filter, tertiary filter is provided with in described filtering area; Described grade one filter, secondary filter, tertiary filter form by some filter elements, and described filter element is square structure, and side, described filter element gas outlet is provided with trapezoidal outlet, and described trapezoidal outlet is provided with some concavo-convex trapezium structures.The utility model adopts quadratic filter element to replace original cartridge structure, decrease air force consumption, filter element exit is provided with trapezoidal outlet, air in exit because space diminishes gradually, air pressure increases, flow velocity is accelerated, and without the need to additionally installing pulse cleaning system and power supply, reduces production cost.
Description
Technical field:
The utility model belongs to field of air filtration, particularly a kind of still air filter.
Background technology:
During existing air cleaner work, gas enters workspace from inlet valve, needs power supply in filter process, also needs to install pulse cleaning system, adds production cost.
The information being disclosed in this background technology part is only intended to increase the understanding to general background of the present utility model, and should not be regarded as admitting or imply in any form that this information structure has been prior art that persons skilled in the art are known.
Utility model content:
The purpose of this utility model is to provide a kind of still air filter, thus overcomes above-mentioned defect of the prior art.
For achieving the above object, the utility model provides
Still air filter, comprising: filter housings, filtering area, rain cap; Described filter housings side is provided with rain cap; Filtering area is provided with in described filter housings; Grade one filter, secondary filter, tertiary filter is provided with in described filtering area; Described grade one filter, secondary filter, tertiary filter form by some filter elements, and described filter element is square structure, and side, described filter element gas outlet is provided with trapezoidal outlet, and described trapezoidal outlet is provided with some concavo-convex trapezium structures.
Compared with prior art, the utility model has following beneficial effect:
Adopt quadratic filter element to replace original cartridge structure, decrease air force consumption, filter element exit is provided with trapezoidal outlet, air is in exit because space diminishes gradually, and air pressure increases, and flow velocity is accelerated, without the need to additionally installing pulse cleaning system and power supply, reduce production cost.
Accompanying drawing illustrates:
Fig. 1 is the utility model front view;
Fig. 2 is the utility model top view;
Main Reference Numerals illustrates:
1-filter housings, 2-filtering area, 3-rain cap, 4-grade one filter, 5-secondary filter, 6-tertiary filter, 7-filter element, the trapezoidal outlet of 8-, the concavo-convex trapezium structure of 9-.
Detailed description of the invention:
Below detailed description of the invention of the present utility model is described in detail, but is to be understood that protection domain of the present utility model not by the restriction of detailed description of the invention.
Clearly represent unless otherwise other, otherwise in whole description and claims, term " comprise " or its conversion as " comprising " or " including " etc. by be understood to include the element of stating or part, and do not get rid of other element or other part.
As shown in Figure 1-2, a kind of still air filter, comprising: filter housings 1, filtering area 2, rain cap 3; Described filter housings 1 side is provided with rain cap 3; Filtering area 2 is provided with in described filter housings 1; Grade one filter 4, secondary filter 5, tertiary filter 6 is provided with in described filtering area 2; Described grade one filter 4, secondary filter 5, tertiary filter 6 form by some filter elements 7, described filter element 7 is excessively square structure, side, described filter element 7 gas outlet is provided with trapezoidal outlet 8, and described trapezoidal outlet 8 is provided with some concavo-convex trapezium structures 9.
When gas is through rain cap 3, after entering filtering area 2 first through grade one filter 4 filter out in gas about 20% dust, pollen, earth and other particles; Again through secondary filter 5 filter out in gas about 50% dust, pollen, earth and other particles; Again through tertiary filter 6 filter out in gas 99.95% dust, pollen, earth and other particles.Quadratic filter element 7 is adopted to replace original cartridge structure, decrease air force consumption, filter element 7 exit is provided with trapezoidal outlet 8, air in exit because space diminishes gradually, air pressure increases, flow velocity is accelerated, and without the need to additionally installing pulse cleaning system and power supply, reduces production cost.
The aforementioned description to concrete exemplary of the present utility model is to illustrate and the object of illustration.These descriptions not want the utility model to be defined as disclosed precise forms, and obviously, according to above-mentioned instruction, can much change and change.The object selected exemplary embodiment and describe is to explain certain principles of the present utility model and practical application thereof, thus those skilled in the art can be realized and utilize various different exemplary of the present utility model and various different selection and change.Scope of the present utility model is intended to limited by claims and equivalents thereof.
