Description

Technical Field

[0001] The present application relates to the technical field of discharge structures, and in particular to a discharge structure of a mixing tank. Background Art

[0002] In the production process of plastic packaging containers, a key link is to mix and stir various plastic particles (such as bottle-grade polyester chips, polyethylene, polypropylene, etc.) so that they can be evenly melted and formed into the required packaging containers, such as plastic packaging bags and plastic bottles.

[0003] In the prior art, this step is typically accomplished using a mixing tank, which consists of a tank body and an internal stirring assembly. The tank body is designed with an inlet and a discharge port, while the stirring assembly includes a stirring motor located at the top of the tank body and stirring blades within the tank body. During operation, mixed plastic particles are injected into the mixing tank through the inlet, and the stirring motor drives the stirring blades to evenly stir the materials. Finally, the mixed materials are discharged through the discharge port for subsequent melting processing.

[0004] However, during the actual production process, some plastic granules may contain small amounts of metal particles (such as iron filings). When these metal-laden materials are discharged from the mixing tank outlet and melt-processed, the presence of these metal particles can seriously affect the quality of the finished plastic packaging container. To address this issue, the traditional approach is to add a metal particle screening step after mixing. However, since the amount of metal particles is usually small, screening alone is not only inefficient but also increases production costs. This clearly represents a process that urgently needs optimization and leaves room for improvement. Utility Model Content

[0015] Optionally, a first magnetic block is embedded on the locking plate, and a second magnetic block is embedded on the outer periphery of the discharge pipe, and the first magnetic block and the second magnetic block can be magnetically attracted to each other.

[0016] By adopting the above technical solution, when the extension tube is installed and the locking protrusion is inserted into the locking through hole, the first magnetic block on the locking plate and the second magnetic block on the outer periphery of the discharge tube abut and magnetize each other, thereby further improving the installation stability of the extension tube.

[0017] Optionally, an elastic sealing ring is provided on the side of the extension tube close to the discharge tube, and the lower end edge of the discharge tube is pressed against the side of the elastic sealing ring away from the extension tube.
