Description

Technical Field

[0001] This utility model relates to the technical field of magnesia-carbon brick drying equipment, specifically a magnesia-carbon brick drying equipment for electric furnace ladles. Background Technology

[0002] Magnesia-carbon bricks for electric arc furnace ladles are refractory materials made primarily from fused magnesia, high-purity magnesia, and graphite. They are produced through high-pressure molding and low-temperature treatment. These bricks possess advantages such as high-temperature strength, corrosion resistance, and spalling resistance, and are widely used in key components of thermal equipment such as electric arc furnace linings, steelmaking converters, electric arc furnaces, steel ladles, and ladle refining furnaces. The main components of magnesia-carbon bricks include fused magnesia, high-purity magnesia, and graphite. During manufacturing, these raw materials undergo high-pressure molding and low-temperature treatment to form a product with excellent corrosion resistance and good thermal shock performance.

[0003] For example, the rapid drying equipment for steel ladle magnesia-carbon bricks disclosed in the authorization announcement number CN217585108U includes a drying kiln body, which is arranged horizontally and has an open design on both sides. Both sides of the drying kiln body are provided with furnace doors that can be opened and closed vertically. A cooling chamber body is arranged horizontally next to the furnace door on one side of the drying kiln body. The cooling chamber body is open on both sides and is horizontally aligned with the drying kiln body.

[0004] Although it enables the magnesia-carbon bricks to be quickly cooled to room temperature by the air-cooling components of the cooling chamber after being pushed out of the drying kiln body, thus shortening the cooling cycle of the magnesia-carbon bricks, it is also beneficial to shorten the drying cycle of the magnesia-carbon bricks. The storage component is equipped with multiple horizontally arranged storage wings for placing magnesia-carbon bricks. At the same time, the storage wings are perforated plates, which replaces the method of stacking magnesia-carbon bricks into the drying kiln body. This allows the magnesia-carbon bricks to be heated quickly and evenly during the heating and drying process in the drying kiln body, which is beneficial to further shorten the drying cycle of the magnesia-carbon bricks.

[0005] However, the existing magnesia-carbon brick drying equipment does not solve the problem that it is generally not convenient to simultaneously dry multiple groups of magnesia-carbon bricks in the kiln, it is not convenient to rotate and adjust the height of the magnesia-carbon bricks, it is not convenient to uniformly receive hot air flow for drying, and it is easy to have local temperature imbalances that affect the drying quality. Therefore, it affects the efficiency of the magnesia-carbon brick drying equipment in batch drying multiple groups of magnesia-carbon bricks simultaneously in the kiln. Utility Model Content

[0007] To achieve the above objectives, this utility model provides the following technical solution: a drying device for magnesia-carbon bricks used in electric furnace ladles, comprising a slide rail and a sliding plate. Three sets of equally spaced sliding plates are arranged on the outside of the slide rail. A rotating disk is arranged on the outside of each sliding plate. A lifting plate body is arranged on the outside of each rotating disk. Three sets of equally spaced kiln bodies are arranged on the outside of each lifting plate body. Exhaust fans are installed on the side walls of each kiln body. Multiple sets of machine feet are installed at the bottom of the slide rail. Four sets of rotating shafts are symmetrically and movably installed at the bottom of each sliding plate. Electric wheels are fitted onto the surface of each rotating shaft.

Each of the rotating disks has a rotating shaft movably installed at its bottom end, and the rotating shaft extends through the bearing seat to its outside. Each of the rotating shafts has a large gear installed at its bottom end, and the small gear meshes with the large gear.

[0010] Preferably, the top of the top plate is equipped with multiple sets of equally spaced support seats, and each support seat has a movably installed roller, which is slidably connected to the rotating disk.

[0011] Preferably, stepper motors are symmetrically installed on the side wall of the kiln body on one side of the lifting plate body, and each stepper motor has a threaded rod installed at its output end, and each threaded rod has a threaded block fitted on its surface.

[0012] Preferably, the threaded rod is threadedly connected to the threaded block, and the threaded block is connected to the lifting plate body. The side wall of the lifting plate body is symmetrically provided with sliding grooves.

[0013] Preferably, sliders are symmetrically installed on the side wall of the kiln body on one side of the lifting plate body, the sliding groove is slidably connected to the sliders, and heating wires are provided inside the kiln body.

[0014] Preferably, a power motor is installed at the top of each kiln body, the power motor extends through the kiln body into its interior, and a fan blade is installed at the output end of each power motor.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the magnesia-carbon brick drying equipment not only enables the convenient simultaneous drying of multiple groups of magnesia-carbon bricks in the kiln, but also facilitates the rotation and height adjustment of the magnesia-carbon bricks, and ensures uniform reception of hot airflow for drying operations. Furthermore, it avoids local temperature imbalances that could affect the drying quality, thus improving the efficiency of the magnesia-carbon brick drying equipment in batch drying multiple groups of magnesia-carbon bricks simultaneously in the kiln.

[0016] (1) Magnesia-carbon bricks are placed on the surface of multiple rotating discs.

This realizes that the magnesia-carbon brick drying equipment can conveniently dry multiple sets of magnesia-carbon bricks in the kiln at the same time, and improves the efficiency of the magnesia-carbon brick drying equipment in batch drying multiple sets of magnesia-carbon bricks in the kiln at the same time.

[0017] (2) The servo motor drives the support shaft to rotate, the support shaft drives the small gear to rotate, the large gear drives the rotating shaft and the rotating disk to rotate. Under the sliding support of the roller and the rotating disk, the rotating disk drives the magnesia-carbon brick to rotate. When the height needs to be adjusted for drying, the electric push rod drives the top plate to move up and down. The top plate drives the support seat, roller, rotating disk and magnesia-carbon brick to move to a certain height for drying. This facilitates the rotation and height adjustment of the magnesia-carbon brick, and makes it convenient for the magnesia-carbon brick drying equipment to rotate and adjust the height of the magnesia-carbon brick. It also facilitates the uniform reception of hot air flow for drying operations and avoids local temperature imbalance that affects the drying quality.

[0018] (3) The stepper motor drives the threaded rod to rotate, the threaded rod drives the threaded block to move up and down, the threaded block drives the lifting plate body to move up and down, so that the lifting plate falls down and shields the kiln body. This makes it convenient to adjust the position of the lifting plate for protection, and realizes the convenient adjustment of the position of the lifting plate for protection in the magnesia-carbon brick drying equipment, thus improving the convenience of adjusting the position of the lifting plate for protection in the magnesia-carbon brick drying equipment.
