Abstract

The invention discloses an operating mechanism for controlling a discharge outlet of a furnace, which consists of pedestals, a hand wheel, a locking sleeve, a body, a rotating shaft, a beam, a bumper pin, a pin boss, a pin shaft, a choke plug, a push rod, connecting rods, a spring, a stop lever, a balancing weight, a handle and a locking ring. The beam is arranged outside the furnace and the pedestals are horizontally arranged on the beam. The rotating shaft is a stepped shaft, is in movable fit with the pedestals, and is limited by the locking sleeve to move. The two ends of the body are provided with a mounting hole respectively, and are in clearance fit with the rotating shaft and the push rod respectively; the connecting rods are arranged on the two sides of the body, and are fixedly connected with the rotating shaft; and the pin boss and the stop lever are arranged above the body. One end of the push rod is provided with the choke plug, while the other end is provided with the pin shaft. One end of each connecting rod is fixedly connected with the rotating shaft, while the other end is provided with an elongated slot; and the pin shaft can slide in the slots. The spring is arranged on the lateral surface of the body, the connecting rods and the body are kept opposite, the rotating shaft is fixedly connected with the hand wheel, the hand wheel is a certain distance away from the discharge outlet and a groove is formed on a wheel flange to accommodate the balancing weight so as to adjust eccentric moment and make operation labor-saving. The rotating shaft is in threaded connection with the locking ring and the locking ring is provided with the handle to lock the position of the choke plug.

Description

technical field [0001] The invention relates to an operating mechanism for controlling the discharge port of a melting furnace. Background technique [0002] In the smelting and casting industry, melting furnaces and holding furnaces are often used in combination. The melting furnace is set above the holding furnace, and the discharge port of the melting furnace faces the downstream holding furnace. The temperature is relatively stable in the casting temperature range required by the product to ensure the casting quality of the product. The discharge port of a small furnace is generally made of graphite material, and is often blocked by a metal plug with an asbestos paper cup. In order to avoid the high temperature of the furnace mouth of the holding furnace, the operator installs a long handle behind the conical metal plug. Even so, the working environment is still quite bad, and there is a danger of being scalded by splashing melt when the plug is removed. The operator h...
