technical field

The utility model relates to an extrusion die, in particular to an extrusion die with a single die head and multiple biological filler profiles, belonging to the technical field of sewage treatment.

Background technique

With the rapid development of the national economy, the sewage collection and treatment facilities are seriously lagging behind, causing a large amount of sewage to directly enter the river. At present, most rivers have become black and odorous water bodies, and the water quality standards cannot meet the requirements of cross-section assessment. Management, and profile extrusion is an important link in the production process of new biological filler travel switches suitable for the growth of water microorganisms.

The extrusion die is a kind of forming die, but its discharging method is to realize the image through the action of extrusion. It is widely used in aluminum special-shaped structures and is also used in plastic parts. At the front end of the extruder, it is used to make pipes or profiles. In short, a mold is a tool used to shape an item. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the article by changing the physical state of the formed material.

The traditional machine extruder die, one die one profile extrusion method makes the profile production efficiency lower, and the melt direction is in a "T" shape structure during extrusion production. When the resistance is large and the flow is divided, a large energy consumption is required to maintain the melt temperature. And each die must have an independent heating device to maintain the melt temperature. The energy consumption is relatively large.
