[0002] In the process of plastic processing, a screw extruder is used to heat, plasticize and extrude the plastic. Although the existing screw extruder can meet the use requirements to a certain extent, since the recycled plastic contains a large amount of metal and non-metal impurities, if these metal and non-metal impurities directly enter the subsequent process after being processed by a single screw extruder, it will have a serious impact on the quality of the product. Therefore, the screw extruder needs to be equipped with a filtering device for filtering.

[0003] In the prior art, the technical scheme of the Chinese patent document (Announcement No.: CN206937949U, Patent Name: A Screw Extruder Pressure Alarm Device) discloses "including a material tank, a screw extruder, a filter and a die head, the screw extruder includes a barrel, a feeding screw, a feeding motor and a reduction box for driving the feeding screw, the upper part of one end of the barrel is connected to the material tank, and the other end is connected to the inlet end of the filter, and the outlet end of the filter is connected to the die head; a pressure gauge I is installed between the screw extruder and the filter, a pressure gauge II is installed between the screw extruder and the die head, the pressure gauge I is connected to the alarm, the pressure gauge II is connected to the controller, and the controller is connected to the feeding motor."

[0004] According to the description and drawings of the patent document, the material of the screw extruder is sent to the barrel, extruded and transported by the screw, filtered by the filter, and extruded by the die head. However, one end of the filter is connected to the barrel, and the other end of the filter is connected to the die head. When replacing the filter, the die head needs to be disassembled before the filter can be replaced, which is not convenient. In addition, the prior art also has Figure 1 As shown, the filter seat 2 of the filter device is installed sideways. When the material enters the base 1 and is filtered by the filter element 202, the material filtered by the filter element 202 is extruded through the upper end of the base 1. When multiple screw extruders are connected in combination, the side installation and disassembly is not fast enough. Utility Model Content
