Heat exchange and cooling device of smelting furnace and operation method thereof

Abstract

The invention discloses a heat exchange and cooling device of a smelting furnace, and relates to the heat exchange and cooling device and an operation method thereof. A horizontal type smelting furnace body is fixedly connected with two flange plates; a plurality of driving rotating rods are arranged between the two flange plates; two annular sealing plates are arranged on the plurality of drivingrotating rods in a sleeved mode; the two ends of the driving rotating rods are fixedly provided with gears; inner teeth are arranged on the inner wall of a rotating cylinder and are engaged with theplurality of gears; driving rotating rods are positioned between the flange plates and the annular sealing plates and are sleeved with pressure springs; the middle of each driving rotating rod is provided with a screw lever; screw nuts are arranged on an extrusion water spraying ring and are in threaded connection with the screw levers; a plurality of water passing pipe heads are arranged on the surfaces of the two sides of the extrusion water spraying ring in a staggered mode; the water passing pipe heads incline towards the outer wall of the horizontal type smelting furnace body; a circle ofouter teeth are arranged on the outer wall of the rotating cylinder; a servo motor is provided with a driving wheel, and the driving wheel is engaged with a circle of outer teeth of the rotating cylinder; and the annular sealing plates fixedly communicate with a water inlet pipe and a water discharging pipe respectively. The reciprocating movement of the extrusion water spraying ring is realizedby controlling the steering angle of the servo motor, and cooling water is jetted through the water passing pipe heads to realize heat exchange and cooling.

Description

technical field [0001] The invention relates to a heat exchange cooling device and an operating method, in particular to a heat exchange cooling device and an operating method for a smelting furnace. Background technique [0002] Smelting is a refining technology, which refers to the extraction of metals from ores by means of roasting, smelting, electrolysis, and the use of chemicals, to reduce impurities contained in metals or to increase certain components in metals, so as to produce the required metals The smelting furnace is a necessary stove for metal smelting. [0003] In order to speed up the cooling speed and improve the heat exchange efficiency during the processing of the smelting furnace, it is usually equipped with a heat exchange cooling device, which is generally divided into an electromechanical control cooling heat exchange system with more induction elements and a water-cooled heat exchange pipeline with a lower cost.

Problems solved by technology

[0003] In order to speed up the cooling speed and improve the heat exchange efficiency during the processing of the smelting furnace, it is usually equipped with a heat exchange cooling device, which is generally divided into an electromechanical control cooling heat exchange system with more induction elements and a water-cooled heat exchange pipeline with a lower cost. The former The effect can be monitored in real time, but the cost is high, and the service life is not long. Compared with the latter, the latter is more widely used, but the problem is that the cooling water flows in the pipeline, which increases the heat conduction distance, and the heat exchange and cooling efficiency is low.
