[0021] First, some terms involved in this utility model are explained:
[0022] Ultra-high molecular weight polyethylene (UHMWPE) refers to unbranched linear polyethylene with a molecular weight of more than 1.5 million.
[0023] The ultra-high molecular weight polyethylene lined composite pipe refers to a liner pipe made of ultra-high molecular weight polyethylene arranged inside a steel pipe, that is, an ultra-high molecular weight polyethylene lined pipe; and the ultra-high molecular weight polyethylene lined pipe is integrated with the steel pipe by interference fit to form a composite pipe.
[0024] Among them, the ultra-high molecular weight polyethylene liner pipe is generally prepared by an extrusion process. Before extrusion, it is generally necessary to mix the powdered materials. The powdered materials include ultra-high molecular weight polyethylene, high-density polyethylene, silicon nitride, talcum powder, PE wax and masterbatch.
[0025] like Figure 1 , Figure 2 As shown, the extruded material mixing device provided by the utility model includes a bracket 1, and the bracket 1 is, for example but not limited to, a welded frame bracket 1. Of course, in other examples, brackets 1 of other structures can also be used, as long as they can support the dust cover 4, the stirring device, etc. described below.
[0026] A dust cover 4 is disposed above the bracket 1 , and the dust cover 4 can be fixed on the bracket 1 by welding, screwing, riveting, etc.
[0027] The dust cover 4 may be a cover body made by sheet metal processing. Of course, in other examples, the dust cover 4 made of plastic material may be made by blow molding, blister molding or other plastic processing techniques. The dust cover 4 has a cavity inside, and the cavity is used to set the stirring device described below.
[0028] The dust cover 4 is provided with a stirring device, which is used to stir the ultra-high molecular weight polyethylene, high-density polyethylene, silicon nitride, talcum powder, PE wax and masterbatch, etc., to fully mix them, and provide them to the subsequent extrusion equipment after the mixing is completed to continue to form the inner liner made of ultra-high molecular weight polyethylene. The mixed raw materials can be directly provided to the extrusion equipment, or they can be provided to the extrusion equipment after passing through other transition equipment; the transition equipment is, for example, but not limited to, a secondary stirring device.
[0029] The dust cover 4 is provided with an inspection port 13, and the inspection port 13 is connected to the inspection door 6. By providing the inspection port 13 in the dust cover 4, the staff can enter the dust cover 4 through the inspection port 13 for inspection. When inspection is not required, the inspection port 13 can be closed by the inspection door 6.

[0031] By arranging the storage bin 2 below the support 1, it is convenient for the staff to pour the raw materials to be mixed into the storage bin 2. The "below" mentioned here can be directly below or sideways below. In order to prevent the support 1 from affecting the staff from pouring the raw materials to be mixed into the storage bin 2, preferably, the storage bin 2 can be arranged obliquely below the support 1 to avoid the support 1.

[0039] A filter is provided in the dust removal suction pipe 10 to filter out the dust sucked out from the dust cover 4, thereby preventing the dust from being directly discharged into the external environment.
[0040] By connecting a dust collecting bag to the dust removal suction pipe 10, the dust sucked out from the dust cover 4 can be collected in the dust collecting bag. After a certain amount is collected, it is transferred to the storage bin 2 for reuse to avoid waste.
