Heating device for cooking boiler

Abstract

The invention discloses a heating device for a cooking boiler. The device belongs to a heating jacket part of an experimental cooking boiler body, and is applied to heating the cooking boiler. A traditional heating manner for the cooking boiler comprises resistance trace heating and steam heating, and the temperature precision in the heating process is difficult to control. Electric heating is slow, thus a short circuit is easily caused; due to the high pressure, the steam heating process has hidden troubles and complex facilities are provided. The heating device heats up heat conduction liquid in a cavity which is formed between the heating device and the cooking boiler body, so that the cooking boiler body is heated up in an intermittent manner; the heat conduction liquid is integrally coated on the cooking boiler body, so that the cooking boiler is quickly, uniformly and stably heated up; the heating device is kept in the normal pressure the same as the atmosphere in the heating process, additional pressure is not applied, and external vapour is not accessed, thus the facilities are simple and the operation is safe; a rotary part is added to achieve the synchronous rotation of the cooking boiler and the heating device.

Description

technical field [0001] The invention relates to a heating device for an experimental cooking pot used for pulp cooking experiments. The device can be used for heating the body of cooking pots in the papermaking industry, chemical fiber industry, textile industry and chemical industry. Background technique [0002] The heating methods of existing experimental cooking pots can basically be divided into two types: direct heating with resistance wire and intermittent heating with water vapor. [0003] The cooking pot directly heated by the resistance wire has a fast heating speed. Due to the heat storage performance of the resistance wire, after the cooking pot reaches the cooking temperature requirement, even if the power is cut off, the resistance wire will continue to release heat, which makes it difficult to accurately control the temperature; and Often the pre-set cooking temperature will be exceeded by several degrees, and even the set temperature will be exceeded by nearl...

AI Technical Summary

Problems solved by technology

[0005] Therefore, the existing heating method cannot achieve stable, efficient and uniform cooking of the cooking raw materials; and there are defects such as dangerous operation or cumbersome heating device.
