Description

Refrigerator air filtering edge-sealing activated carbon

Technical Field

The utility model belongs to the technical field of filtration, and particularly relates to refrigerator air filtration edge sealing activated carbon.

Background

Activated carbon is a specially treated carbon produced by heating an organic raw material (husk, coal, wood, etc.) in the absence of air to reduce non-carbon components (this process is called carbonization), and then reacting with a gas to erode the surface and produce a structure with developed micropores. The diameter of micropores on the surface of the activated carbon is mostly between 2 nm and 50nm, even a small amount of activated carbon has huge surface area, and the surface area of each gram of activated carbonIs 500-²。

Because different kinds of food need to be stored in the refrigerator, the odor emitted by various foods is difficult to mix in the refrigerator and is easy to discharge, so that the peculiar smell in the refrigerator is large, bacteria are easy to nourish, and the foods are polluted.

The active carbon can effectively adsorb peculiar smell in the refrigerator and purify the air in the refrigerator. However, the existing activated carbon for the refrigerator is generally bagged. The bagged active carbon is piled up, the contact area with the air in the refrigerator is reduced, and a large amount of active carbon cannot exert the adsorption capacity. The air purification requirement in the refrigerator can be met only by more active carbon in unit space, and the expected effect is achieved, so that a large amount of space in the refrigerator is occupied, the utilization efficiency of the active carbon is reduced, and the cost is increased.

As shown in fig. 1-2, an edge-sealed activated carbon for air filtration in a refrigerator comprises a frame body 1, a front filter sheet 2, an activated carbon plate 3 and a rear filter sheet 4 which are sequentially arranged in parallel, wherein the front filter sheet 2 and the activated carbon plate 3 are clamped between the frame body 1 and the rear filter sheet 4, and the periphery of the rear filter sheet 4 is bonded on the frame body 1. Frame 1, preceding filter 2, back filter 4 form the guard action to activated carbon plate 3 for activated carbon has stable, difficult broken stable shape, has stable area of contact with the air when placing it in the refrigerator. The front filter disc 2 and the rear filter disc 4 prevent dust of the activated carbon plate 3 from overflowing into the refrigerator and can form primary filtration on air. The active carbon plate 3 is formed by casting and sintering active carbon powder. The surface of the activated carbon plate 3 is provided with through holes 5, so that the ventilation area is increased, and the filtering efficiency is increased. The activated carbon plate 3 purifies air in the refrigerator to remove peculiar smell, and food materials are guaranteed to be fresh. The activated carbon plate 3 is made of coconut shell activated carbon, and the technical indexes are as follows: the iodine adsorption value is newly 400mg/g, the ctc is more than or equal to 20 percent, the static benzene adsorption is more than or equal to 20 percent, the water content is less than or equal to 5 percent, and no heavy metal exists after the pickling.

Furthermore, cushions 6 are respectively adhered to the periphery of the activated carbon plate 3, and the cushions 6 are clamped between the activated carbon plate 3 and the frame body 1.

Further, the buffer pad 6 is a rubber pad, a pearl wool pad or an EVA pad. The problem of easy fragmentation exists in the industry of the activated carbon plate 3, and a ring of rubber pad/pearl cotton pad/EVA pad with a buffering effect is stuck on the outer side of the activated carbon plate 3, so that the integrity and effectiveness of the activated carbon plate 3 can be ensured.

Furthermore, a cross-shaped reinforcing rib 7 is connected inside the frame body 1. The cross reinforcing rib 7 plays a role in reinforcing the structural strength of the frame body 1 and blocking the front filter disc 2, so that the front filter disc 2 and the activated carbon plate 3 can be fixedly clamped between the frame body 1 and the rear filter disc 4.
