Embodiment Construction

[0014] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0015] The invention makes full use of the waste heat of the kiln, supplemented by a hot blast stove as a heat source, and transports it to the underground pipe network of the drying room through two sets of kiln waste heat utilization systems; The system radiates heat through the underground pipe network of the drying room; when the kiln ceases fire, another set of heat source delivery system is used to transfer heat directly through the underground pipe network of the drying room.

[0016] The present invention includes No. 3 kiln 1, No. 4 kiln 2 and drying room 5; No. 3 kiln 1 and No. 4 kiln 2 communicate with the drying room 5 through the hot air duct 3 before the cease-fire and the waste heat duct 4 after the cease-fire The drying room is built with high-alumina refractory bricks, the top is covered with prefabricated cement board, and th...

Abstract

The invention relates to a method and a device utilizing kiln waste heat for rapidly drying electrotechnical porcelain, wherein the kiln waste heat is fully utilized with the assistance of an air heater serving as a heat source, and then is transferred to an underground pipe network of a drying house through two kiln waste heat utilization systems; during the time from the ignition of the kiln to the stop of the kiln, one of the heat source auxiliary transference system is utilized for transferring heat radially through the underground pipe network of the drying house; and when the kiln is stopped, the other heat source auxiliary transference system is utilized for directly transferring heat through the underground pipe network of the drying house. In the invention, the drying time is reduced to 48 to 96 hours, the turnaround time of the drying house per month increases to 6 to 10 times, as a result, not only is the production period greatly shortened, but also the waste heat is fully completely utilized at the same time; and the heat energy circulates repeatedly from the bottom to the top to form thermal current, so that the heat efficiency is improved and the drying effect is extremely remarkable.

Description

technical field [0001] The invention relates to a method and a device for rapidly drying electric porcelain by utilizing waste heat of a kiln. technical background [0002] The green body drying process after electric porcelain wet forming is to discharge the chemically bound water, adsorbed water and free water in the green body, because they all exist in the green body in different ways, which determines the green body in the drying process. Different ways of water existence adopt different methods, and are removed with different heating rates and relative humidity. [0003] Since the heat and mass between the green body and the drying medium change during the drying process, it is not difficult to analyze that the drying mechanism is mass transfer (that is, the process of discharging water from the green body) and heat transfer (that is, the green body and the drying medium). The process of heat exchange and transfer between drying media and the temperature change of the...
