Large mica tube production equipment

Abstract

The invention provides large mica tube production equipment, and belongs to the technical field of insulating material preparation. The equipment comprises a rack, a driving motor, a heating plate and a pipe die, the pipe die comprises an upper die piece and a lower die piece, the upper die piece and the lower die piece are detachably connected through several connecting pieces, a die cavity is formed between the upper die piece and the lower die piece, the pipe die is located on the heating plate, an air hole coaxial with the die cavity is formed in the lower die piece, the two ends of the lower die piece are connected with the rack through bearings correspondingly, and the driving motor can drive the lower die piece to rotate. The equipment has the advantages that a prepared mica tube is better in insulating property and the like.

Description

technical field [0001] The invention belongs to the technical field of insulating material preparation, and relates to a large-scale mica tube production equipment. Background technique [0002] Mica is a common rock-forming ore. After crushing, bonding, and reprocessing, parts of various shapes can be produced. Since mica itself is a low-energy ore with high fire resistance and insulation, it has many applications in the field of insulation and fire resistance. Among the commonly used mica materials, plates, block billets, round rods, and round tubes are common. The blank, after cutting, can make a variety of parts. [0003] The general pipe material blank is made by mixing mica powder and binder through a pipe mold made of metal, and then pressed by a press and a heater. However, the maximum diameter of the mica pipe that can be made by the existing process is relatively small. Small, its length is relatively short, the most important thing is that its insulation perform...

Problems solved by technology

[0003] The general pipe material blank is made by mixing mica powder and binder through a pipe mold made of metal, and then pressed by a press and a heater. However, the maximum diameter of the mica pipe that can be made by the existing process is relatively small. Small, its length is relatively short, the most important thing is that its insulation performance is poor, the reason is that: due to its physical structure of mica, when it is used as an insulating material, the direction of its scales plays a key role in the size of the insulation Function, when the scales are parallel to the direction of the electric field, the insulation is poor. When the scales are perpendicular to the direction of the electric field, the insulation effect is good. In the existing practice, the mica scales are scattered in the binder, resulting in poor insulation.
