Description

Technical Field

[0001] This utility model relates to the field of screw compressors, specifically to the barrel structure of a screw compressor and the screw compressor itself. Background Technology

[0002] Screw extruders are the main equipment for mixing, dispersing, and plasticizing polymer materials. They rely on the pressure and shear force generated by the heating of the extruder barrel and the friction of the rotating screw to extrude materials after mixing, melting, plasticizing, and dispersing.

[0003] Conventional screw compressors have a hopper on the barrel for feeding. However, during feeding, blockages or bridging can cause feeding problems. This can usually be solved by tapping the outer casing. If a more serious blockage occurs, the hopper needs to be removed to check the opening slot. Because the hopper itself is heavy and the material is difficult to open. Utility Model Content

[0019] The present invention will be further described below with reference to the accompanying drawings. The screw compressor barrel structure includes a barrel body 1 and a hopper 2. The barrel body is provided with an opening slot communicating with the hopper. The barrel body also includes a mounting base 11. One end of the hopper is hinged to the mounting base, and the other end contacts the upper end surface of the mounting base. The side wall of the hopper forms an acute angle α with the horizontal plane, and a counterweight 3 is provided on the side wall. The handle is located on one outer wall of the hopper, and the counterweight is located on the other outer wall. Here, "one side" and "the other side" refer to the center line. In use, the hopper is manually pushed to rotate counterclockwise. The weight of the counterweight reduces the required pushing force, which is equivalent to hanging a heavy object on one end of a seesaw, making it easier to lift. When rotating back to the starting position, there is no difficulty because the internal material has been cleared. At the same time, with the rotating shaft as the reference, the counterweight is on one side and the handle is on the other side.

[0020] In this embodiment, as shown in the figure, a handle 22 is provided on the side wall of the other hopper. This facilitates manual pushing of the hopper.

[0021] In this embodiment, as shown in the figure, the mounting base is disposed on the outer wall of the cylinder, and its central part is provided with a channel 111 connecting the inner cavity of the hopper and the opening slot. The mounting base is disposed on the cylinder and serves as a support, and its central part is provided with a through slot for material to pass through.

[0022] In this embodiment, as shown in the figure, the mounting base is provided with a rotating shaft 112, and the hopper has a shaft hole that mates with the rotating shaft. A rotatable connection can be achieved through a simple hinge structure, and a sealing ring can be provided on the contact surface 113 between the mounting base and the hopper.

[0023] In this embodiment, as shown in the figure, the counterweight is positioned above the rotating shaft.

[0024] In this embodiment, as shown in the figure, the inner wall of the handle is provided with a sponge layer. This makes it easy to grip and prevents cuts.

[0025] In this embodiment, as shown in the figure, the screw compressor includes the screw compressor barrel structure described above.
