Description

Technical Field

[0001] The utility model relates to the technical field of refractory material preparation, and more specifically to a vibrating cleaning device for magnesia coarse material. Background Art

[0002] Magnesia, also known as sintered magnesia, is made from magnesite, magnesite or magnesium hydroxide produced by the reaction of seawater and lime milk and calcined at high temperature. It has strong hydration ability and is mainly used to make alkaline refractory materials, such as magnesia bricks and magnesia-aluminum bricks. Magnesia containing many impurities is used to pave the bottom of steelmaking furnaces. Magnesia coarse material needs to be cleaned during its production process.

[0003] After searching, the utility model patent with announcement number CN214348268U discloses a vibrating cleaning device for magnesia coarse material, including a pit, a tray, a roller, a cleaning trough, a motor, a crank, a connecting rod and a spring; the tray is placed at the bottom of the pit, the roller is placed on the top of the tray, and the cleaning trough is placed on the top of the roller; the bottom of the cleaning trough is provided with an impurity leakage hole; the motor is fixed on the ground outside the pit, and under the drive of the motor, the crank rotates around the motor shaft, driving the cleaning trough to move back and forth in the horizontal direction through the connecting rod; spring retaining grooves are respectively provided on both sides of the upper part of the pit corresponding to the moving direction of the cleaning trough, and the length of the spring retaining groove is greater than or equal to the length of the spring; a plug plate is provided in the middle of the spring retaining groove, and the plug plate can be lifted upward; this patent drives the cleaning trough to move back and forth in the horizontal direction through the motor and the crank-connecting rod mechanism, and realizes horizontal vibration through the spring, thereby screening out impurities wrapped in the magnesia coarse material and fine sand that does not meet the use requirements, and its cleaning efficiency is high and it is easy to use.

[0004] However, the above patent has the following shortcomings: the device pours magnesia coarse material into the cleaning tank, causing some impurities and fine sand to be vibrated and filtered into the tray. However, the magnesia coarse material accumulates at the bottom of the cleaning tank, blocking the leakage hole at the bottom of the cleaning tank, resulting in the fine sand being unable to be filtered out through the leakage hole; and the cleaning tank is immersed in water. After the cleaning tank is lifted out, the magnesia coarse material is in a wet state, which is not convenient for subsequent processing. To this end, we propose a vibrating cleaning device for magnesia coarse material. Utility Model Content

[0038] In this embodiment, the first filter screen 19 is provided to facilitate water to enter the interior of the inner box 5 and prevent the magnesia coarse material from leaking out of the inner box 5 .

[0039] For details, please refer to Figure 7 A threaded groove 24 is provided on the side of the bottom end of the upper splicing block 22, and a bolt 23 is sleeved on the side of the top end of the lower splicing block 21. The end of the bolt 23 is threadedly installed into the inner cavity of the threaded groove 24.

[0040] In this embodiment, the upper splicing block 22 and the lower splicing block 21 are disassembled by the cooperation of the bolts 23 and the threaded grooves 24, so that the screening box 4 and the inner box 5 can be disassembled from the cleaning device.

[0041] Working principle: When in use, first start the electric telescopic rod 3 to pull the upper splicing block 22 and the lower splicing block 21 upward, so that the screening box 4 moves upward from the outer box 1, and then pour the magnesia coarse material that needs to be cleaned into the inner box 5. At the same time, fill the outer box 1 with clean water, and then start the electric telescopic rod 3 again to move the screening box 4 and the inner box 5 downward to the inside of the outer box 1 through the upper splicing block 22 and the lower splicing block 21. When the screening box 4 moves to the inside of the outer box 1, the water in the outer box 1 enters the inner box 5 through the first filter 19 and the screen 17. , thereby soaking the magnesia coarse material in the inner box 5, and at the same time starting the first motor 10 to rotate the cam 11, and the rotation of the cam 11 and the return elastic force of the spring 9 drive the inner box 5 to move up and down to generate vibration. The vibration of the inner box 5 can make the impurities and smaller magnesia particles in the magnesia coarse material pass through the screen 17 and the discharge port 18 and fall to the bottom of the outer box 1. While the magnesia coarse material is vibrating, cleaning and screening, the second motor 12 is also started to rotate the reciprocating screw 13, and the threaded fit between the reciprocating screw 13 and the movable block 14 drives the movable block 14 and the connecting block 14. The connecting rod 31 and the flip plate 32 move back and forth, and the flip plate 32 is used to scrape the magnesia coarse material on the screen 17 to assist in separating impurities in the magnesia coarse material. After the magnesia coarse material in the inner box 5 is cleaned, the electric telescopic rod 3 is started again to lift the screening box 4 and the inner box 5 upward from the outer box 1 through the lower splicing block 21 and the upper splicing block 22, and at the same time, the heating pipe 28 and the fan 27 in the drying box 29 are started, and the fan 27 is used to blow air to the magnesia coarse material in the inner box 5, and the heating pipe 28 is used to heat the wind, and the hot air is used to clean the magnesia coarse material in the inner cavity of the inner box 5. The coarse sand material is dried, and the flip plate 32 continues to flip the magnesia coarse sand, and the cam 11 continues to rotate to make the inner box 5 vibrate, ensuring that the cleaned magnesia coarse sand is completely dried. Finally, the user unscrews the bolt 23 from the inside of the thread groove 24, thereby disassembling and separating the lower splicing block 21 from the upper splicing block 22. The separation of the lower splicing block 21 and the upper splicing block 22 can facilitate the removal of the screening box 4 from the support frame 2 to process the cleaned and dried magnesia coarse sand, and open the water outlet valve 30 to discharge the waste water after cleaning the magnesia coarse sand in the outer box 1.

[0042] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and improved ideas of the present invention, which should be covered by the protection scope of the present invention.
