Description

Technical Field

[0001] The utility model relates to the technical field of medical waste treatment equipment, in particular to a medical waste incineration metal pre-screening device. Background Art

[0002] Medical waste is infectious, toxic and other harmful waste generated by medical institutions in medical, preventive and health care activities. Medical waste contains a large number of pathogenic microorganisms and harmful chemicals, which will pose a great threat to human health. Therefore, my country stipulates that waste must be strictly handled. Common treatment methods are incineration or pyrolysis. In order to avoid the spread of pathogenic microorganisms and harmful chemicals in the treatment process of medical waste, unpacking is not allowed before incineration or pyrolysis. Usually, the whole package of waste is incinerated or pyrolyzed. However, in the prior art, there is no classified collection of metal utensils in medical waste. Therefore, the metal utensils mixed in medical waste not only increase the difficulty of incineration and pyrolysis, but also cause a certain waste of resources; and the waste residue after incineration and pyrolysis contains a large amount of metal slag, which also affects the treatment and utilization of the waste residue.

[0003] Patent number CN219559991U discloses a medical waste incineration metal pre-screening device, including a box body, a medical waste conveying mechanism and a metal conveying mechanism arranged in the box body, the metal conveying mechanism is arranged above the medical waste conveying mechanism and partially staggered along the conveying direction; the metal conveying mechanism includes a bracket connected to the box body, a metal conveying belt rotatably arranged on the bracket, a driving member driving the metal conveying belt to rotate, and a magnetic suction block arranged between the metal conveying belts and connected to the box body or the bracket; a metal collection space corresponding to the end of the metal conveying mechanism and a mixed waste collection space corresponding to the end of the medical waste conveying mechanism are respectively provided in the box body. The medical waste conveying mechanism conveys the input medical waste, and during the conveying process, the metal in the medical waste is adsorbed on the metal conveying belt and sent into the metal collection space by the metal conveying mechanism and the magnetic suction block arranged above, so as to separate the metal from other waste materials and collect them. When the medical waste conveying mechanism is shaking, it may cause the medical waste to fall from the side of the conveying mechanism, causing some medical waste to enter the mixed waste collection space without passing through the metal conveying mechanism, or the medical waste may be unevenly spread and the metal in the medical waste cannot be adsorbed by the metal conveying mechanism, resulting in incomplete metal collection. Utility Model Content

[0004] The utility model provides a medical waste incineration metal pre-screening device, which solves the problem of incomplete collection of metals in medical waste in the prior art.

[0005] The technical solution of the utility model is achieved in this way:

[0006] A medical waste incineration metal pre-screening device comprises a screening outer cylinder, an inclined screening inner cylinder is arranged in the screening outer cylinder, a driving mechanism for driving the screening inner cylinder to rotate is arranged on the screening outer cylinder, a metal collecting plate arranged along the axis of the screening inner cylinder is arranged in the screening inner cylinder; a magnetic suction piece is arranged on the outer wall of the screening inner cylinder, an inner cylinder inlet is arranged at one end of the screening inner cylinder, a metal outlet and a mixed waste outlet are arranged at the other end of the screening inner cylinder, the metal outlet corresponds to the position of the metal collecting plate, and the inner cylinder inlet and the mixed waste outlet are both located at the lower side of the collecting plate.
