Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
Referring to fig. 1, fig. 1 is a schematic view of an activated carbon filter according to the present application.
The application provides an activated carbon filter which mainly comprises a filter bottle cap 1, a filter cup body 2, a filter screen 3 and activated carbon 4.
The filter bottle cap 1 is internally provided with an inlet channel 11, an outlet channel 12 and a screen mounting part 13, the inlet channel 11 and the outlet channel 12 are circular section pipelines, wherein the inlet end of the inlet channel 11 is arranged at the edge of the filter bottle cap 1 and is transversely communicated with the screen mounting part 13 in the center of the filter bottle cap 1, and the screen mounting part 13 is communicated with the screen channel in the filter screen 3. The outlet end of the outlet channel 12 is arranged at the edge position of the other side of the filter bottle cap 1 opposite to the inlet end, and is communicated with the activated carbon installation cavity and the external pipeline inside the filter cup body 2. The screen mounting portion 13 is provided at the inner bottom of the filter cap 1 for mounting the filter screen 3. The filter screen 3 is tubular structure, and its upper end cover is adorned on screen mounting portion 13, is linked together with the filtration gas import, and the hollow structure of filter screen 3 is the screen cloth passageway, and the screen cloth passageway is linked together in the active carbon installation cavity.
The upper end of the filter cup body 2 is detachably connected with the filter bottle cap 1, an activated carbon installation cavity is arranged in the filter cup body 2 and used for providing a place for gas filtration, and activated carbon 4 is arranged in the activated carbon installation cavity and used for filtering and drying gas.
The gas to be filtered enters the inlet end of the filter bottle cap 1 through a pipeline or a pipeline combination joint, enters the screen passage of the filter screen 3 through the inlet passage 11, flows into the activated carbon 4 through the outlet hole below the filter screen 3, slowly flows upwards below the filter cup 2, flows out of the outlet end through the outlet passage 12 of the filter bottle cap 1 after being filtered by the activated carbon 4, and flows to an external pipeline or container after being filtered. The gas filtration is completed. The active carbon filter that this scheme provided, simple structure, simple to operate easily dismantles and changes active carbon 4, can reduce filtering cost.
In order to improve the filtering effect, a plurality of air outlet slots 31 may be formed in the lower region of the filtering screen 3, the air outlet slots 31 are disposed on the filtering screen 3 near the bottom surface of the filter cup 2, and the air outlet slots 31 are distributed in an array along the axial direction and 360 degrees of the circumferential direction of the filtering screen 3. Each air outlet slot 31 is communicated with the active carbon installation cavity, so that the filtered gas is introduced into the active carbon 4 of the active carbon installation cavity for filtering, the over-utilization of the local active carbon 4 can be avoided, and meanwhile, the contact efficiency of the filtered gas and the active carbon 4 can be improved.
In order to prevent the activated carbon 4 particles from entering the sieve passage, the size of the air outlet slots 31 should be smaller than the particle size of the activated carbon 4 particles, not only to prevent the activated carbon 4 particles from entering the sieve passage, but also to facilitate the processing of the filter sieve 3 and to prevent clogging. The air outlet slot hole 31 can be in the shape of a round slot, a square slot and the like, the air outlet slot hole 31 can be processed in a cutting mode, and compared with the traditional punching processing mode, the air outlet slot hole 31 is more convenient to process and is not easy to block. The air outlet slots 31 are preferably uniformly circumferentially distributed on the filter screen 3 so that air is uniformly introduced into the activated carbon 4 everywhere and slot processing is facilitated.
Preferably, the filter screen 3 extends to the bottom of the filter bowl 2, i.e. extends into the bottom of the filter bowl 2, so that the contact time between the filtered gas and the activated carbon 4 can be prolonged, and the filtering efficiency can be improved.
In order to facilitate the installation of the activated carbon filter, a filter bracket 5 can be installed at the top of the filter bottle cap 1, and the filter bracket 5 is fixedly connected with the filter bottle cap 1 through locking pieces such as screws. When in installation, the activated carbon filter is arranged on the wall body through the filter bracket 5 and the locking piece.
The active carbon filter provided by the application has an efficient filtering structure, and the gas can meet the use requirement after being filtered and dried. When the activated carbon 4 is installed, the activated carbon 4 can be filled by opening the filter bottle cap 1 and the filter cup body 2. After the active carbon 4 is invalid, the filter bottle cap 1 and the filter cup body 2 are opened, the invalid active carbon 4 is replaced, other parts of the filter can be reused, and the cost is saved.
It should be noted that in this specification relational terms such as first and second are used solely to distinguish one entity from another entity without necessarily requiring or implying any actual such relationship or order between such entities.
The activated carbon filter provided by the application is described in detail above. The principles and embodiments of the present application have been described herein with reference to specific examples, the description of which is intended only to facilitate an understanding of the method of the present application and its core ideas. It should be noted that it will be apparent to those skilled in the art that various modifications and adaptations of the application can be made without departing from the principles of the application and these modifications and adaptations are intended to be within the scope of the application as defined in the following claims.
