Calcium carbonate processing device for flame-retardant cable

Abstract

The invention discloses a calcium carbonate processing device for a flame-retardant cable, and belongs to the technical field of calcium carbonate processing of the flame-retardant cable. The calcium carbonate processing device comprises a motor, a shell and a hollow driving shaft, the motor is fixedly arranged on the upper end surface of the shell, and a feeding hole is formed above the shell; the hollow driving shaft is rotatably connected to the axis of the shell and penetrates through the upper end surface of the shell; and a plurality of groups of rolling mechanisms are arranged on the outer wall of the hollow driving shaft, each rolling mechanism comprises a rolling plate, the rolling plates are fixedly arranged on the outer wall, located at the lower end of the shell, of the hollow driving shaft, the middles of the rolling plates are low, the edges of the rolling plates are high, and a plurality of non-uniform and non-equidistant crushing strips are fixedly arranged on the rolling plates. The problems that the processing requirement of the flame-retardant cable cannot be directly met due to the fact that calcium carbonate forms a whole after being dewatered and the blocky calcium carbonate is crushed through vibration of a vibrator, and secondly, the crushing efficiency is low due to the fact that in the existing calcium carbonate crushing process, a roller is blocked by the largest blocky calcium carbonate are solved.

Description

technical field [0001] The invention relates to the technical field of calcium carbonate processing for flame-retardant cables, in particular to a calcium carbonate processing device for flame-retardant cables. Background technique [0002] Calcium carbonate is an inorganic compound with the chemical formula CaCO 3 , commonly known as gray stone, limestone, stone powder, marble and so on. Calcium carbonate is neutral, basically insoluble in water, soluble in hydrochloric acid. It is one of the common substances on the earth. It exists in aragonite, calcite, chalk, limestone, marble, travertine and other rocks. It is also the main component of animal bones or shells. Calcium carbonate is also an important building material and is widely used in industry. [0003] In the invention case of a calcium carbonate processing device for flame-retardant cables disclosed in the prior art, the Chinese patent application number of the invention patent is CN201811145204.9, a calcium ca...

AI Technical Summary

Problems solved by technology

[0006] The object of the present invention is to provide a kind of calcium carbonate processing device that is used for flame-retardant cable, to solve the above-mentioned background technology, propose that existing equipment adopts the mode of extruding to carry out dehydration, makes calcium carbonate form a whole after dehydration, and then passes through The vibrator vibrates to crush the block calcium carbonate, but the calcium carbonate obtained after extrusion is condensed together and has a relatively high viscosity, and the calcium carbonate cannot be crushed into a fine state only by vibration, so it cannot directly meet the processing requirements of flame-retardant cables Secondly, in the existing calcium carbonate crushing process, the roller is hindered by the largest block calcium carbonate, so it is impossible to quickly crush all the calcium carbonate into powder, and it can only be crushed bit by bit until all the calcium carbonate in the whole crushing device is crushed. Unloading can only be carried out when the technical requirements are reached, which leads to the problem of low crushing efficiency
