Description

Technical Field

[0001] The utility model relates to the technical field of rock wool production, in particular to a rapid curing furnace for rock wool production. Background Art

[0002] Rock wool products are internationally recognized as the main energy-saving materials in the "fifth conventional energy" for their excellent fireproof and heat-insulating properties. Every ton of rock wool products used for insulation in buildings can save at least 1 ton of oil energy per year, which is in line with the trend of low carbon, energy saving and emission reduction. Rock wool products are made of high-quality basalt, dolomite, etc. as the main raw materials. After being melted at a high temperature of more than 1450°C, they are centrifuged into fibers using an internationally advanced four-axis centrifuge at high speed. At the same time, a certain amount of adhesive, dust-proof oil, and water-repellent are sprayed in, and then collected by a cotton collector, and solidified and cut after being spread by the pendulum method and the three-dimensional method to form rock wool of different specifications and uses.

[0003] In the production process of rock wool products, it is necessary to spray binder and dust-proof oil on rock wool fibers, and then heat, cure, cut and other processes to form finished products. During curing, a curing furnace is usually used to heat the semi-finished rock wool products. In order to polymerize the resin in the cotton felt, a hot air blower is needed to send hot gas at a temperature of 300-350℃ into the heating zone of the curing furnace to effectively cure the rock wool products.

[0004] A curing furnace for rock wool production disclosed in the Chinese utility model patent application disclosure CN210718621U, the rock wool board follows the conveyor chain board to move into the furnace, and during the movement, the stepper motor is started to drive the diffusion blade to rotate slowly, so as to break up the high-temperature airflow flowing out of the wind hood, so as to avoid the high-temperature airflow directly blowing the rock wool board to cause surface wrinkles, which affects the curing quality of the rock wool board. At the same time, the rotating diffusion blade can accelerate the diffusion of the high-temperature airflow, so that the high-temperature airflow inside the curing furnace is evenly distributed, and the curing efficiency of the rock wool product is improved; by using a wire brush to brush off the carbonized impurities attached to the surface of the conveyor chain board, it can effectively avoid that the impurities on the surface of the conveyor chain board after long-term use affect the curing effect, and play a good role in energy saving and consumption reduction. The carbonized impurities brushed off by the wire brush fall into the inside of the collection tray, which is convenient for cleaning. However, since the wind hood structure is fixedly connected to the top of the entire furnace shell, it is not convenient to disassemble and clean it. The dust adsorbed for a long time will affect the hot air circulation and contact with the rock wool board inside, affecting the efficiency of subsequent curing.

[0005] Secondly, the connection method between the collection plate and the furnace shell and furnace structure is vague. Whether the staff can quickly dismantle it in the later stage to facilitate the processing of the carbonized impurities collected inside needs to be developed urgently. Utility Model Content
