Description

Technical Field

[0001] This utility model relates to the field of screening machine technology, specifically a wear-resistant castable screening machine. Background Technology

[0002] Wear-resistant castables are a type of castable composed of refractory aggregates, refractory powders, binders, and additives. They possess excellent wear resistance and can operate for extended periods in high-temperature, high-pressure, high-speed, and corrosive environments without easily wearing down or breaking. The particle size distribution of wear-resistant castables has a significant impact on their performance. Screening can classify castables according to different particle size ranges, resulting in a more uniform particle size distribution and thus improving the performance of the castable. Therefore, screening machines are necessary for screening wear-resistant castables.

[0003] Because wear-resistant castables contain certain sticky components, large particles can easily stick together with other particles under the action of stickiness, forming large clumps that clog the screen. Alternatively, the mesh size of the screen may not match the size of the large particles in the wear-resistant castable, causing the large particles to accumulate on the screen and become blocked, thus affecting the screening process. Therefore, a wear-resistant castable screening machine is proposed. Utility Model Content

[0029] This utility model provides a technical solution: a wear-resistant castable material screening machine. Please refer to [link / reference]. Figure 1 , Figure 2 and Figure 3 ,include:

[0030] The screening shell 1 has a first filter screen 15 installed at the upper end of its interior.

An electromagnet 5 is provided at the upper end of the interior of the bottom box 4, and a vibration damping pad 11 is provided at the upper end of the electromagnet 5, and the vibration damping pad 11 is connected to the electromagnet 5.

[0034] The electric lifting rod 7 is located inside the base box 4, and the upper end of the electric lifting rod 7 is rotatably mounted with a support roller 8 via a bracket;

[0035] Vibration motor 9 is located on the outer side of screening shell 1;

[0036] Side hopper 20 is located on the outer side of the screening shell 1;

[0037] Side frame 16 is located on the front and rear sides of the bottom box 4. A storage hopper 17 is provided on the upper part of the side frame 16. A drive motor 18 is installed inside the storage hopper 17. A spiral conveying blade 19 is installed at the output end of the drive motor 18.

[0038] Please see Figure 1 and Figure 2 A discharge shell 10 is provided on the side of the screening shell 1 away from the side bucket 20, and the discharge shell 10 is connected to the screening shell 1. The discharge shell 10 is used to discharge the screened wear-resistant castable material.

[0039] Please see Figure 2 A flap 21 is provided on one side of the lower interior of the side bucket 20, and the flap 21 is rotatably connected to the side bucket 20.

[0040] Please see Figure 2 A magnetic strip 22 is provided on the outside of the side bucket 20 at the lower end of the flap 21, and the magnetic strip 22 is connected to the side bucket 20. The magnetic strip 22 is used to attract the flap 21 to close it.

[0041] Please see Figure 2 and Figure 3 A backflow preventer 24 is provided at the lower end of the screening shell 1 near the side hopper 20. The backflow preventer 24 is connected to the screening shell 1 via a spring-loaded shaft. The backflow preventer 24 opens when the end of the screening shell 1 near the discharge shell 10 is tilted downwards, and closes when the end of the screening shell 1 near the side hopper 20 is tilted downwards.

[0042] Please see Figure 2 and Figure 3 The screen shell 1 is provided with a second filter screen 23 on the outside side of the anti-reverse plate 24.

The second filter screen 23 is used to return the small particles that fall into the side hopper 20 with the large particle inner membrane casting material to the screen shell 1.

[0043] This scheme involves pouring the wear-resistant castable into the storage hopper 17, starting the drive motor 18 and the vibration motor 9, causing the drive motor 18 to drive the spiral conveyor blades 19 to rotate, allowing the wear-resistant castable to fall onto the upper end of the first filter screen 15, and the vibration motor 9 to vibrate the screening shell 1, thereby causing the first filter screen 15 to vibrate and screen the castable. When it is necessary to clear blockages, the drive motor 18 and the vibration motor 9 are turned off, the electromagnet 5 is turned off to release the adsorption and fixation of the pallet 6, and the electric lifting rod 7 is started to cause the roller 8 to lift the screening shell 1, thereby causing the screening shell 1 to move towards the side hopper 2. The first filter screen 15 is flipped over until the end of the first filter screen 15 near the side hopper 20 is lower than the end of the first filter screen 15 near the discharge shell 10. The rotating rod 14 rolls along the chute 13 under the action of gravity, thereby pushing the large particles at the upper end of the first filter screen 15 to the right and falling into the side hopper 20. This can be repeated so that the rotating rod 14 pushes all the large particles into the side hopper 20. Then, the screening shell 1 is reset and the electromagnet 5 is turned on to fix the tray 6. The vibration motor 9 and the drive motor 18 are turned on to continue the screening work. The large particles that fall into the side hopper 20 can be taken out by lifting the flap 21.
