Description

Technical Field

[0001] The utility model relates to the technical field of refrigerator freshness preservation, in particular to a novel palladium catalyst freshness preservation block manufacturing device for a refrigerator. Background Art

[0002] In the freshness preservation drawer of a refrigerator, a palladium catalyst freshness preservation block is generally placed specifically. The palladium catalyst freshness preservation block can help delay the ripening and senescence of fruits and vegetables by absorbing and decomposing ethylene, thereby maintaining their freshness.

[0003] After retrieval, the patent with the publication number CN1132673C discloses a refrigerator catalyst freshness preservation block and its manufacturing method. In the process of manufacturing the palladium catalyst freshness preservation block, first, a certain proportion of powdered palladium and activated carbon are placed in a container and stirred for a certain time to make the powdered palladium fully adhere to the surface of the activated carbon to form palladium-impregnated carbon; then, the binder polyethylene, the catalyst manganese oxide, and the palladium-impregnated carbon are mixed and filled into a mold; then, heating and sintering are carried out, and after cooling, it is taken out. However, in the actual operation process of the existing palladium catalyst freshness preservation block manufacturing device, there are the following deficiencies in the mixing of raw materials:

[0004] First, the stirrer arranged inside the container has a simple structure. The stirring rod can only make a circular motion around the rotating shaft, and the blades on it cannot rotate by themselves, so that the mixing effect between raw materials is poor, reducing the manufacturing effect of the subsequent palladium catalyst freshness preservation block.

[0005] Second, during the discharging process, only relying on a simple discharging pipe for discharging, due to the low fluidity of the raw materials, the situation of raw material accumulation and blockage is likely to occur, reducing the discharging rate. Summary of the Utility Model
