Integral structure of molded-coal vacuum hard-plastic extruding machine

Abstract

The invention discloses an integral structure of a molded-coal vacuum hard-plastic extruding machine. The integral structure comprises an upper machine part, a lower machine part and a supporting part. The upper machine part comprises a first motor, a first speed reducer, a hopper, an agitating tank, a screw propelling auger and a discharging box, wherein the first motor, the first speed reducer, the hopper, the agitating tank, the screw propelling auger and the discharging box are sequentially arranged from the right end to the left end. The lower machine part comprises a second motor, a second speed reducer, a connecting box, a vacuum chamber, a vacuumizing device, an extruding auger and a mold outlet device, wherein the second motor, the second speed reducer, the connecting box, the vacuum chamber, the vacuumizing device, the extruding auger and the mold outlet device are sequentially arranged from the front end to the back end. The vacuum chamber of the lower machine part is communicated with the discharging box of the upper machine part through the connecting box. Vacuumizing operation is carried out on the vacuum chamber through the vacuumizing device. The integral structure of the molded-coal vacuum hard-plastic extruding machine has the advantages that molding products are not prone to damage, the extruding pressure is large, the molding water content is low, drying is easy, and fire resistance is good; molded coal in multiple shapes can be produced, multiple requirements of users can be met, and production efficiency is high.

Description

technical field [0001] The invention relates to the technical field of briquette production equipment, in particular to an overall structure of a briquette vacuum hard plastic extruder. Background technique [0002] In the daily briquette production process, the briquette briquette machine is also called coal powder briquette machine, which can be used to press coal powder and iron powder. Mainly; cold press forming is divided into binder forming and binder-free forming, mainly with binder forming. At present, the general pulverized coal molding mostly adopts the process of adding binder, medium and low pressure, no drying, and cold pressing. [0003] In the past ten years, the briquette production technology is still under repeated construction at a low level, and many problems in the briquette production process cannot be broken through, which seriously restricts the industrialization of briquette. The main reason is that the basic research on molding is weak. Therefore...

AI Technical Summary

Problems solved by technology

The transmission part of the prior art briquetting machine is driven by an electromagnetic speed-regulating motor. If the feeding amount is too large, the motor of the feeding device will be overloaded, resulting in failure of normal production and operation.

2. Mold compression strength is low

The molding part of the prior art briquetting machine is formed by pressing, so the finished product has low compactness, is easy to break, and has poor fire resistance

3. Single product style

The briquette briquetting machine of the prior art cannot meet the various needs of users
