Detailed Description

The vacuum extruder shown in fig. 1-5 comprises a frame 1, wherein an outer cylinder 2 is arranged on the frame 1, an inner cylinder 3 is arranged in the outer cylinder 2, an auger 4 is arranged in the inner cylinder 3, one end of the inner cylinder 3 is provided with a feeding hole 34, and the other end of the inner cylinder 3 is provided with a discharging hole 35; the inner cylinder 3 at least comprises a first inner cylinder 31 and a second inner cylinder 32 which can be spliced with each other.

Specifically, the inner tube includes first 31, two 32 of inner tubes and three 33 of inner tubes, the one end of two 32 of inner tubes is equipped with setting element 36, and the other end is equipped with constant head tank 37, the one end of first 31 of inner tubes is equipped with feed inlet 34, and the other end is equipped with the constant head tank 37 with two 32 setting element 36 adaptations of inner tubes, the one end of three 33 of inner tubes is equipped with discharge gate 35, and the other end is equipped with the setting element 36 with two constant head tank 37 adaptations of inner tubes.

More specifically, a first limiting portion 38 is disposed on a side wall of the bottom of the positioning slot 37, and a second limiting portion 39 capable of adapting to the first limiting portion 38 is disposed at a position of the positioning element 36 corresponding to the first limiting portion 38; through the arrangement, when the inner barrel needs to be disassembled, when the inner barrel is pulled to be the third, the first limiting parts and the second limiting parts can be matched, so that the second inner barrel and the first inner barrel are also pulled out together, and the outer barrel is pulled out and then disassembled.

More specifically, the number of the positioning grooves 37 and the positioning elements 36 on the second inner cylinder 32 is greater than or equal to 2, and 3 or 4 positioning grooves can be provided, in this embodiment, 2 positioning grooves are preferably provided, and the structural stability of the inner cylinder is affected due to the excessive number of the positioning grooves.
