Description

Technical Field

[0001] The utility model relates to the technical field of antibacterial and antiviral melt-blown material production, in particular to a masterbatch heating mixing tank with a heat-insulating structure. Background Art

[0002] The production purpose of antibacterial and antiviral meltblown materials is to prevent bacteria and kill viruses as the main modification purpose. Copper, silver and zinc work synergistically. Copper is good at attacking the protein / amino acid of the cell wall, so that silver and zinc can easily invade the cell. Copper, silver and zinc are prepared into antibacterial and antiviral masterbatch in a certain proportion, and then the antibacterial and antiviral masterbatch is mixed with meltblown PP masterbatch, extruded by a screw extruder, and then stretched into antibacterial and antiviral meltblown material by high temperature and high pressure airflow, which is used for the construction and production of H13 grade meltblown filter materials, which is convenient for the production of protective clothing and other equipment.

[0003] When the existing device mixes the antibacterial and antiviral masterbatch with the melt-blown PP masterbatch in a tank body and needs to heat and melt it, when the heating element is placed inside the tank body, it is easy for the molten material to adhere to the surface of the heating rod. When placed outside the tank body, it is easy to lose heat, resulting in the internal temperature failing to reach the rated peak value, both of which will affect the heating effect, causing uneven heating and partial melting.

[0004] Therefore, in view of this, the existing structure and deficiencies are studied and improved, and a masterbatch heating mixing tank with a heat-insulating structure is proposed, in order to achieve a more practical purpose. Utility Model Content
