Description

High efficiency filter

The utility model relates to a filter, in particular to an innovative structure in which an activated carbon filter layer is axially installed on a primary filter layer. All the water that passes through the primary filter layer enters from one end of the activated carbon filter element and exits from the other end. After being completely filtered by activated carbon, clean drinking water can be obtained.

Nowadays, most water sources are seriously polluted. Even after a series of filtration and disinfection in waterworks, the water quality is still quite poor. Therefore, various high-efficiency water filters have emerged as the times require.

Generally, the water filter only has the effect of filtering coarse particles or filtering mud, sand, solid sediment, etc., but has no filtering effect on bacteria, fine impurities or heavy metals, so it is generally connected with a filter with activated carbon filter to filter the water for further filtering. However, to install two independent filters in the water pipeline obviously takes up quite a lot of space, which is actually not ideal, but in order to obtain clean water quality, it has to be implemented in this way, and it is necessary to improve .

The inventor actively researches, develops, and through trial production many times, creates the technical scheme of the utility model.

The purpose of this utility model is to provide a high-efficiency filter, which uses the activated carbon filter core installed in the primary filter layer, so that after the water penetrates through the primary filter layer, water enters from one end of the activated carbon layer and exits from the other end, greatly reducing the volume of the filter And the space occupied by the installation, and has clean water quality.

The purpose of this utility model is achieved in that:

A high-efficiency filter, characterized in that: a hollow space is formed in the central axis of the primary filter layer interwoven by several layers of filter materials; the activated carbon filter core is installed in the hollow space and formed with the inner surface of the primary filter layer. Water flow spacing, the interior of the activated carbon filter core is axially hollowed to accommodate activated carbon, and there are several gaps on the lower edge; the lower cover is embedded under the activated carbon filter core; the upper cover is embedded in the active carbon filter core. On the top of the carbon filter core, there are holes on the top surface.

The surface of the activated carbon filter core is axially provided with several convex ribs, and the outer edge of the convex ribs is offset against the inner surface of the primary filter layer, forming a proper water flow distance between the activated carbon filter core and the primary filter layer.

Cotton sleeve is sheathed on the inside of the active carbon filter core.

A center block is arranged at the center of the lower cover, and several rows of sheets are arranged around the center block. The rows of sheets are radially arranged, and water flow channels are formed between adjacent rows of sheets. The gaps and interiors of the activated carbon filter core are connected.

A plurality of L-shaped sheets are arranged inside the upper cover, and the L-shaped sheets are radially arranged, and water flow channels are formed between adjacent L-shaped sheets, which communicate with the openings on the top surface.

The main advantage of the utility model is that two kinds of filter cores with different filtering effects are skillfully combined into one body, which greatly reduces the space occupied by installation, and has a higher filtering effect to meet the demand for clean water.

Below with preferred embodiment for further description in conjunction with accompanying drawing:

Fig. 1 is a structural exploded view of the utility model;

Fig. 2 is a schematic longitudinal section of the utility model;

Fig. 3 is a schematic cross-sectional view of the utility model.

Referring to Fig. 1, Fig. 2, Fig. 3, the utility model comprises just filtering layer 1, activated carbon filter core 2, lower cover 3, cotton cover 4 and loam cake 5, and wherein just filtering layer 1 is by the filter material of several layers, as Cotton material is interwoven, and the central axis forms a hollow space 10. The activated carbon filter core 2 is installed in the hollow space 10 of the primary filter layer, and its interior axially forms a hollow accommodating space 22 to accommodate activated carbon, and the surface axially There are several convex ribs 20 of triangular or other protruding structures, and the outer edge of each convex rib 20 is offset against the inner surface of the primary filter layer 1, so that a water flow distance 6 of an appropriate size is formed between the activated carbon filter core 2 and the primary filter layer 1. The lower edge of the filter core 2 is provided with some gaps 21, the lower cover 3 is embedded under the activated carbon filter core 2, and the central block 30 is surrounded by rows of sheets 31, and each row of sheets 31 is radially arranged so that the space between each adjacent row of sheets 31 The water flow channel 32 is formed, the cotton sleeve 4 is installed above the activated carbon filter core 2, the upper cover 5 is embedded above the activated carbon filter core 2 and clamps the cotton sleeve 4, the upper part is an opening 52, and several L Each L-shaped row of sheets 50 is radially arranged, and each adjacent L-shaped row of sheets 50 forms a water flow channel 51 and communicates with the opening 52.

When the utility model is used, the water first penetrates through the primary filter layer 1 and enters the inner surface, leaving large particles of impurities such as mud sand and solid sediment outside the primary filter layer 1. There is a water flow interval 6, and its top and bottom are sealed by the upper cover 5 and the lower cover 3, and there are only some gaps 21 on the surface below the activated carbon filter core 2, so the water in the water flow interval 6 naturally flows in through the gaps 21, And enter the interior of the activated carbon filter core 2 through each water flow channel 32 . Since the only flow position of the water flow interval 6 is set at the lower edge of the activated carbon filter core 2, in other words, all water must enter the interior from the bottom of the activated carbon filter core 2 after being filtered through the primary filter layer 1, and the activated carbon filter core The interior of the filter 2 contains activated carbon, and the upper end is embedded with a cover 5, and a water flow channel 51 is reserved, so once it enters the activated carbon filter element 2, it gradually goes upwards, and then flows out from the water flow channel 51 through the opening 52 . In this way, all the water flowing out can be ensured to be filtered by the activated carbon core 2, which has a very significant effect on the elimination of bacteria and impurities.

To sum up, the simplified structural design of the utility model enables the primary filter layer 1 and the activated carbon filter core 2 to have an appropriate combination effect, which not only solves the defect that two commonly used filters occupy a large space, but also improves the quality of filtered water. Clean, sterile, with high filtration efficiency, to meet the needs of actual use.
