Detailed Description

As shown in fig. 1, the squeezing granulator according to the embodiment of the present invention includes a material cylinder assembly and a screw 3 disposed in the material cylinder assembly, wherein the material cylinder assembly is formed by connecting a front material cylinder 1 and a material cylinder 2 from left to right through bolts, the front material cylinder 1 includes a front material cylinder 12, the left side of the front material cylinder 12 is fixedly connected to a front connecting flange i 11, and the right side of the front material cylinder 12 is fixedly connected to a rear connecting flange ii 13; the charging barrel 2 comprises a charging barrel body 22, the left side of the charging barrel body 22 is fixedly connected with a front connecting flange III 21, and the right side of the charging barrel body 22 is fixedly connected with a rear connecting flange IV 23; and a feed opening 221 is processed at the upper part of the right side of the cylinder body of the charging barrel, a water outlet 224 is processed on the cylinder body of the charging barrel along the circumferential direction, the contact part of the water outlet and the screw rod is a small inner side hole, and the other side of the water outlet is a large outer side hole. And three garbage grooves 231 are processed at the rear connecting flange IV and are uniformly distributed at positions with a central angle of 60 degrees below the contact surface of the rear connecting flange IV and the screw rod. Preceding feed cylinder barrel passes through flange I before the threaded connection, and seam crossing adopts welded fastening, and preceding feed cylinder barrel passes through flange II 13 behind the threaded connection, and seam crossing adopts welded fastening. The front barrel body is provided with a cooling groove 121 along the circumferential direction. The screw 3 is divided into a screw rear end connecting portion 31, a feeding portion 32, an extruded thermoplastic portion 33, and a discharging portion 34 from the right to the left. The left side of the charging barrel body is fixedly connected with a front connecting flange III, the seam is fixedly welded, the right side of the charging barrel body is fixedly connected with a rear connecting flange IV, and the seam is fixedly welded. An elongated groove 223 is axially formed in the inner wall 222 of the barrel body, the elongated groove continues to the front barrel, and the damping strip 24 is fixed at the elongated groove through a bolt.

The water outlet is processed along the circumferential direction on the cylinder body of the charging barrel, so that most of water flows out through the water outlet when the raw material is extruded by the screw, and the large structure inside and outside the water outlet ensures that the raw material cannot block the water outlet and the drainage to the maximum extent is realized. Three garbage chutes are uniformly distributed below the contact surface of the rear connecting flange IV and the screw along the position with the central angle of 60 degrees, and the distribution structure ensures that garbage is convenient to discharge and granulation quality. The damping strips are axially arranged on the charging barrel assembly, so that raw materials are stirred to a certain extent in the extrusion process, and the pressure release is generated at the gaps among the damping strips along with the increase of the space, so that the extruded raw materials generate a turbulent flow phenomenon, and are stirred more uniformly; and meanwhile, the damping strip is convenient to replace when worn. The charging barrel is connected with the front flange and the rear flange by adopting a thread welding technology, so that the concentricity can be ensured, and the material cost is saved.

In particular use, the invention will be described with reference to the accompanying drawings for the convenience of understanding;

add old and useless plastics or film sanitization back at the feed opening, the screw rod rotates and drives the material and transport to left, because the extrusion of spiral shell arris to the raw materials, has produced pressure at the feeding position for most moisture in the raw materials passes through the delivery port and flows, accomplishes furthest's drainage when the big outer major structure of interior little of delivery port guarantees that the raw materials can not block up the delivery port. Meanwhile, due to the special-shaped design of the screw, backward thrust can be generated on the raw materials, and the garbage in the raw materials is discharged through the garbage groove. When pressure enters the extrusion thermoplastic section, the outer diameter of the spiral rib is in contact with the damping strips, so that the raw material is stirred to a certain degree in the extrusion process, the gap between the damping strips of the raw material is released along with the increase of the space to generate pressure, the extruded raw material generates a turbulent flow phenomenon, and the stirring is more uniform. And then granulating after discharging through a discharging section.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
