Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of shade drying, specifically relates to an airflow tumbling type mud section shade drying chamber. BACKGROUND

[0002] In the production process of the electric porcelain wet method, the mud section is usually made by mud refining and extrusion into a cylindrical shape. However, the mud section is soft due to high moisture content, and cannot be repaired. Therefore, the mud section needs to be treated by shade drying first, so that the moisture content of the mud section is reduced from 19% to 22% to 15% to 17%. In order to shorten the shade drying time of the mud section and improve the production efficiency, the mud section is generally placed upside down, and electrodes are arranged at both ends of the mud section and powered on. The moisture content of the mud section is controlled by controlling the voltage, current and drying time. That is, the auxiliary drying by electric heating is used instead of the conventional natural shade drying method, so that the electric shade drying becomes an indispensable process in the production of large electric porcelain products.

[0003] The electric drying method is generally placed in a single layer in an open workshop, which occupies a large space and has a low space utilization rate. Therefore, the patent with the publication number CN206593387U discloses a drying device, which is equipped with a trolley. At least two layers of mud section loading layers are arranged in the trolley. Then, power supply electrodes are connected to both ends of the mud section. The number of electric wires in the unit space is increased, so that the electric wires of the upper and lower layers overlap, causing the electric wires to be disordered and prone to incorrect connection. At the same time, the electric shade drying method also increases the power consumption in the production of electric porcelain, thereby increasing the production cost.

[0004] The utility model patent with the publication number CN201715820U also discloses a direct combustion type electric porcelain wet base drying system. An air inlet pipe network is arranged at the bottom of the drying chamber, and an air return pipe network is arranged at the top of the drying chamber. A circulating fan, a gas combustion machine and a combustion air fan connected with the gas combustion machine are arranged outside the drying chamber. The gas combustion machine has a gas pipe, a combustion air inlet and a hot air outlet. The combustion air inlet is connected with the outlet of the combustion air fan. The hot air outlet is connected with the inlet of the air inlet pipe network. The inlet of the circulating fan is connected with the outlet of the air return pipe network, and the outlet is connected with the inlet of the air inlet pipe network through a circulating air pipe. In this way, the air is directly heated by the gas combustion machine, and the hot air is circulated by the circulating fan to complete the drying of the electric porcelain body. The economic gas is used as the fuel gas to reduce the production cost. However, when the drying system is used for mud section shade drying, the mud section is prone to uneven shade drying, which affects the normal operation of the subsequent repair process. SUMMARY
