Longitudinal-circulation autoclave provided with external thermal-cold cycling device

Abstract

The invention relates to a longitudinal-circulation autoclave provided with an external thermal-cold cycling device. The longitudinal-circulation autoclave comprises a main tank body, air suction connection pipelines, air blowing connection pipelines and the thermal-cold cycling device, wherein the main tank body is connected with airflow distributors through the air suction connection pipelines and the air blowing connection pipelines respectively; the thermal-cold cycling device is located outside the main tank body. According to the autoclave with the structure, the complicated heating, cooling and circulating device is moved out of the main tank body, and loading rate is remarkably increased; the circulation path is shortened by means of a new longitudinal-circulation mode, and under cooperation with the airflow distributors, the temperature distribution in the tank is uniform, vertical temperature difference is reduced, and front and back temperature difference is almost zero; with adoption of an electromagnetic heating mode with higher efficiency, not only is energy saved, but also efficiency is remarkably improved; the external thermal-cold cycling device can be wholly replaced and dismounted for maintenance due to presence of spare parts, and the condition of production delay caused by equipment failure maintenance is avoided.

Description

technical field [0001] The present invention relates to the equipment for completing the lamination process in the pressure vessel—the autoclave, that is, the equipment that realizes firm bonding and solidification of two or more layers of materials through adhesives under high temperature and high pressure conditions, especially relates to a peripheral cold storage tank. Longitudinal circulation autoclave for thermal cycler. Background technique [0002] The production of laminated glass and the curing of carbon fiber composite materials must use pressurized heating, cooling and curing equipment with a circulation device. The current horizontal quick-opening door pressure vessel tank. This kind of equipment is generally equipped with a circulating fan at the end, and a heater and a cooler in front of the fan. During operation, the equipment is heated or cooled according to the process requirements, and the heat and cold are transported to each part of the tank through the f...

AI Technical Summary

Problems solved by technology

However, this kind of equipment has inherent weaknesses since its birth. Due to the effect of gravity, the hotter air rises and the cooler air descends during the horizontal circulation of the air, resulting in not only a temperature difference between the top and bottom of the tank, but also a temperature difference between the front and back. , plus the heat absorption and barrier of the material, the temperature difference between the upper part of the tank near the front door and the rear of the tank near the front of the centrifugal fan suction guide cone is the largest

With the increase of the length and diameter of the equipment, the temperature difference becomes more obvious, resulting in inconsistencies in the cold and hot temperatures of various parts of the product, which seriously affects the implementation of the product process

Although increasing the fan power to enhance the stirring effect can reduce the temperature difference, it is difficult to achieve the desired effect. Excessive fan power will not only cause vibration of materials, but also significantly increase energy consumption.

Also, because the traditional autoclave is designed according to the heater using an electric heater, it is not conducive to the use of new high-efficiency heating methods such as electromagnetic heating and microwave heating, so the backward and inefficient electric heating tube heating method is still used today.
