Embodiment Construction

[0010] Such as figure 1 As shown, the low-temperature rising screw of the rubber extrusion filter is composed of a screw feeding section 1 with 4 threads, a conveying section 2 with 2 threads, and a quantitative section 3 with 4 threads. There is a cooling water channel 4 in the center of the screw. 4. Water is fed into a single hole in the center of the screw, and water is returned in multiple holes around the screw. The length-to-diameter ratio of the screw is 1:3.5. This invention changes the thread structure of the conventional screw, changes the number of threads in the feeding section of the screw, and cuts the wide film into narrow strips. In order to reduce the temperature of the rubber material, the length-to-diameter ratio of the screw is changed, the length of the screw thread in the conveying section is shortened, the heat generated by the conveying distance is reduced, and the number of thread heads in the quantitative section is increased, and the large rubber mat...

Abstract

The invention discloses a low-temperature-rise type screw for a rubber extrusion filter. The low-temperature-rise type screw consists of a four-thread screw charging section (1), a two-thread conveying section (2) and a four-thread quantification section (3), wherein a cooling water channel (4) is formed in the center of the screw. According to the low-temperature-rise type screw for the rubber extrusion filter, by changing a screw structure, the generated heating quantity of a rubber material in an extrusion process is decreased, and the problem of over-high temperature rise of a screw extrusion rubber material for a large-size rubber filter is solved.

Description

technical field [0001] The invention relates to a low-temperature rising screw for a rubber extruding filter. Background technique [0002] In the existing technology, the one-time rubber mixing method is a new rubber mixing process emerging in recent years. The Φ450 large-scale rubber filter machine is a new equipment developed in conjunction with this new process method. The screw in this equipment is The key technology, its structure has a great influence on the temperature rise of the extruded rubber material. In the new rubber mixing process, there are strict requirements on the output and temperature of the rubber material extruded by the rubber filter machine. These indicators are conventional configurations. The screw can't reach it at all. At present, there is no screw type rubber filter of this specification at home and abroad. Contents of the invention [0003] The purpose of the present invention is to provide a rubber extruder that reduces the calorific value...
