Novel pulverized coal high-pressure forming device

Abstract

The invention relates to the technical field of a pulverized coal forming device, and discloses a novel pulverized coal high-pressure forming device. The novel pulverized coal high-pressure forming device comprises a first conveying device, a screening box with a feeding port at the lower portion of the right side, a first screen mesh, a conveying channel, a first lifting device, a second liftingdevice, a supporting plate, a pulverizing hydraulic rod, a pulverizing hammer, a second screen mesh, a second conveying device, a screw pressing device, an electric heating layer, a steam exhaust portand a molding device; pulverized coal is screened and smashed through the screening device, when the size of a molded product needs to be changed, a left adjusting hydraulic rod and a right adjustinghydraulic rod are adjusted to move a left adjusting plate and a right adjusting plate in the same or opposite direction, and extrusion molding products in different sizes are achieved; and the novelpulverized coal high-pressure forming device solves the problem that according to an existing pulverized coal forming device, the pulverized coal contains irregular pulverized coal particles or large-volume pulverized coal briquettes, consequently the compactness of the pulverized coal products is insufficient, the strength is not high, and diversified production of the pulverized coal forming products cannot be achieved.

Description

technical field [0001] The invention relates to the technical field of pulverized coal molding devices, and is a novel pulverized coal high-pressure molding device. Background technique [0002] Coal powder forming technology has been widely used in the field of deep processing of raw coal. For example, in the production of activated carbon, the method of preparing coal-based activated carbon with coal as raw material has been widely used. In order to make the obtained activated carbon have higher strength when used, usually Forming treatment is required before coal is carbonized and activated. Therefore, high-strength coal forming is also the basis for preparing high-strength activated carbon. [0003] The existing pulverized coal molding device has a double-roll molding machine, and the pulverized coal is pressed and formed between the two rollers of the double-roll molding machine. However, when the pulverized coal contains irregular coal particles or has a large volume ...
