The smoke exhaust fan 5 and the movable door 3 realize linkage action through the controller, and the controller detects the opening height of the movable door 3 and controls the wind power of the smoke exhaust fan 5 according to the opening height;
the higher the opening height of the movable door 3 is, the larger the wind power of the smoke exhaust fan 5 is;
The lower the height of the movable door 3 is opened, the smaller the wind power of the smoke exhaust fan 5 is.
The smelting furnace 1 is in a closed cavity structure, a metal ingot to be smelted is placed in the smelting furnace 1 to be smelted, a certain pressure is required to be set in the smelting furnace 1 in order to ensure the melting effect of the smelting furnace 1, a specific pressure value is set according to the material of the metal ingot to be actually smelted, in the embodiment, the metal ingot to be smelted in the smelting furnace 1 is an aluminum ingot, so the preset furnace pressure in the smelting furnace 1 is 65Pa, and the heat and the furnace pressure in the smelting furnace 1 are kept by burning raw materials.
The outer cover 2 surrounds the smelting furnace 1 and is used for collecting heat around the smelting furnace 1, preventing heat from overflowing and wasting energy, and a fan installation position is arranged at the top of the outer cover and is convenient for installing the smoke exhaust fan 5.
The movable door 3 is located at one side of the housing 2, moves up and down along the guide rail 4, and has a width equal to that of the guide rail 4, so that the movable door 3 can move conveniently. In order to facilitate the movement of the movable door 3, the movable door 3 further includes a motor 31 and a wire rope 32 connecting the motor 31 and the movable door 3, and the motor 31 is connected to the controller, and drives the wire rope 32 to retract or extend under the control of the controller, thereby achieving the lifting of the movable door 3.
In order to facilitate the movement of the movable door 3, two ends of the movable door 3 are provided with sliding blocks, the shape and the size of the sliding blocks are matched with those of the guide rail 4, and the sliding blocks are embedded into the guide rail 4 and used for guiding the movement track of the movable door 3 to prevent the position of the movable door 3 from deviating and influence the normal movement of the movable door 3.
The guide rails 4 are positioned on the side walls of the two sides of the outer cover 2, the number of the guide rails is two, the distance between the two guide rails 4 is larger than or equal to the width of the movable door 3, and the movable door 3 is convenient to install and move.
The smoke exhaust fan 5 is located at the fan installation position at the top of the outer cover 2, the wind power of the smoke exhaust fan 5 is determined by the height of the movable door 3, namely, the wind power of the smoke exhaust fan 5 is linked with the height of the movable door 3, the higher the height of the movable door 3 is, the larger the wind power of the smoke exhaust fan 5 is, and conversely, the lower the height of the movable door 3 is, and the smaller the wind power of the smoke exhaust fan 5 is.
The limiting device 6 is used for limiting the lowest height of the movable door 3, is mounted on the guide rail 4 and prevents the movable door 3 from further descending, so as to influence the normal operation of the smelting furnace 1, and specifically, the limiting device 6 is a baffle mounted on the guide rail 4 and blocks the movable door from further descending.
