Abstract

The invention provides a furnace door safety locking device, which relates to the field of melting furnaces, and includes a sealed door, the sealed door includes a sealing plate, a pressure device is provided in the middle of the sealing plate, and the pressure device includes a pressure tube penetrating through the sealing plate, The pressure tube is provided with a piston slidingly connected with it, the top of the pressure tube is connected with a control mechanism, the control mechanism is in transmission connection with the locking mechanism, the locking mechanism is pneumatically connected with the pressure device, and the locking mechanism slides with the sealing plate connected, the side of the pressure pipe communicates with the sliding cylinder, and the sliding cylinder is slidably connected with the locking mechanism. In the present invention, the pressure in the furnace is used to move the piston in the pressure tube, thereby compressing the air in the pressure tube, and the pressure difference inside and outside the pressure tube is used to move the locking mechanism, so that the locking mechanism can connect the sealing plate and the furnace mouth more closely , increase the locking force, more secure.

Description

technical field [0001] The invention relates to the field of melting furnaces, in particular to a furnace door safety locking device. Background technique [0002] Melting furnaces are widely used in metal smelting. During metal smelting, the temperature in the furnace can reach more than 1,000 degrees, resulting in an increase in the pressure in the furnace. Since the furnace door and the furnace mouth are connected in a movable manner, its pressure-bearing capacity is higher than that of a furnace. The rest of the interior is relatively low. If the locking device is loose during the smelting process, the release of pressure in the furnace will easily lead to major accidents. Therefore, the connection and locking methods of the furnace door and the furnace mouth are particularly important. [0003] Most of the existing locking methods are bolted or clipped. The connection is laborious and the locking is not stable enough. Contents of the invention [0004] The object of ...
