Continuous starch cooking equipment for papermaking

Abstract

The invention discloses continuous starch cooking equipment for papermaking. The continuous starch cooking equipment structurally comprises a stock bin, a starch inverted hopper, a connecting box, a spiral conveyor, a dissolving tank, a cooking barrel, a turbidity inhibiting device and a storage barrel. The equipment has the beneficial effects that the stirring loosening structure and the edge fixing and removing mechanism are matched with each other, so that scaling substances formed at the contact end of the inner side wall of the cooking barrel and starch during cooking can be scraped, and the situation that the scaling starch substances formed due to heat energy are burnt to cause black scorched substances to appear on the starch in the whole barrel is avoided; in order to solve the problem that the starch scorched matter which is twisted and removed has scorching flavor and then influences the papermaking quality, the collecting and fishing piece is connected with the arc frame in a penetrating manner, so that under the cooperation of intermittent outward blowing airflow and the arc frame, the starch scorched matter which is twisted and removed is attached and fished and removed under the action of the elastic strip, and the starch scorched matter is prevented from being blended into the starch which is being cooked.

Description

technical field [0001] The invention relates to the field of papermaking equipment, more specifically, to a continuous starch cooking equipment for papermaking. Background technique [0002] Starch is one of the most important raw materials in the papermaking process. In modern large-scale high-speed paper machines, continuous cooking equipment is mostly used to process starch raw materials. [0003] When using continuous cooking equipment for starch processing for papermaking, it often occurs that starch is thicker after cooking, so under the action of continuous increase in temperature, starch and cooking drum are contacted and exposed to air. On the middle side, scaling is formed on the inner side wall of the cooking cylinder, and with the continuous increase of temperature, the scaled starch is scorched, thus forming a black substance, which is integrated into the overall starch, so that the starch after cooking is After being put into paper production, the surface of t...

Problems solved by technology

[0003] When using continuous cooking equipment for starch treatment for papermaking, it often occurs that the starch becomes thicker after cooking, so under the action of rising temperature, the starch is in contact with the cooking drum and exposed to the air. On the middle side, scaling is formed on the inner wall of the cooking cylinder, and with the continuous increase of temperature, the scaled starch is scorched, thus forming a black substance, which is integrated into the whole starch, so that the starch after cooking is completed. After being put into paper production, the surface of the finished paper will be doped with black substances, and the smell produced by burning will be integrated into the interior of the starch
