Description

Technical Field

[0001] This utility model relates to the field of high-alumina castable screening technology, specifically a screening device for processing high-alumina castables. Background Technology

[0002] High-alumina castable is a high-performance refractory material widely used in metallurgy, building materials, chemical and other industries. Its production process requires high uniformity and purity of raw material particles. During processing, the raw materials need to be screened to remove impurities and ensure that the particle size meets the production standards, thereby improving the density, strength and high temperature resistance of the castable. Therefore, an efficient and stable screening device is one of the key equipment in the production of high-alumina castable.

[0003] However, after long-term operation, the screening efficiency of the screen is easily reduced due to the blockage of raw material particles. The existing equipment has insufficient cleaning function, and manual intervention is required after the screen holes are blocked, which not only increases maintenance costs but also affects production efficiency. Therefore, a screening device for high-alumina castable processing is needed to solve the existing shortcomings. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] like Figure 1-4As shown, this utility model provides a technical solution: a sieving device for processing high-alumina castables, including a sieve box 1. A set of symmetrical control wheels 2 are movably connected inside the sieve box 1 via a rotating shaft. A screen 16 is sleeved on the outside of the control wheels 2, and the screen 16 and control wheels 2 form a chain drive structure. Several control blocks 3 are fixedly connected to the outside of the control wheels 2, and the control blocks 3 are adapted to the screen holes of the screen 16, so that the control wheels 2 can both drive the screen 16 to rotate and push out the raw material stuck on the screen holes, preventing them from clogging the screen holes. A guide plate 4 is fixedly connected inside the sieve box 1, and the guide plate 4 is located inside the screen 16. The sieve box 1 is inclined to facilitate the high-alumina castables rolling downwards along the surface of the screen 16 and the guide plate 4. A vibration component 5 is provided on the sieve box 1, and the vibration component 5 is movably connected to the surface of the screen 16. The screen box 1 is movably connected to a cleaning brush 6, which is movably connected to the bottom surface of the screen 16. The bottom of the screen 16 is penetrated by the cleaning brush 6. In addition, an opening can be provided at the bottom of the screen box 1 for the discharge of dust and impurities falling on the screen 16. A reciprocating assembly 7 is fixedly connected to the outside of the screen box 1, and the reciprocating assembly 7 is fixedly connected to the outside of the cleaning brush 6. A drive assembly 8 is fixedly connected to the top of the screen box 1, and the drive assembly 8 is connected to the vibration assembly 5 and the reciprocating assembly 7 respectively. A feed pipe 9 is fixedly connected to the top of the screen box 1, and a discharge pipe 10 and a discharge pipe 2 are fixedly connected to the side of the screen box 1. The discharge pipe 10 is located above the discharge pipe 2. The discharge pipe 10 is used for the discharge of larger particles, and the discharge pipe 2 is used for the discharge of smaller particles.

[0026] like Figure 1 and Figure 3 As shown, the vibration assembly 5 includes roller 1 501, roller 2 502, bracket 1 503, and bracket 2 504. Roller 1 501, roller 2 502, and bracket 2 504 are symmetrically arranged. Roller 1 501 is movably connected to the bottom end of bracket 1 503, and roller 2 502 is movably connected to the top end of bracket 2 504. Roller 1 501 is attached to the top upper surface of screen 16, and roller 2 502 is attached to the top lower surface of screen 16. The vibration assembly 5 also includes folding springs 505. Folding springs 505 are symmetrically arranged and are fixedly connected to the top two sides of guide plate 4. The top ends of folding springs 505 are fixedly connected to the bottom ends of bracket 2 504, and the bottom ends of bracket 2 504 are movably connected to guide plate 4. Bracket 1 503 penetrates the top of screen box 1 and is movably connected to screen box 1.

[0027] Roller 1 501 and roller 2 502 are located on both sides of screen 16, and roller 1 501 and roller 2 502 are on the same straight line. Both roller 1 501 and roller 2 502 are rolledly connected to screen 16, so that when screen 16 rotates, it drives the two rollers to roll. The reciprocating movement of roller 1 501 and roller 2 502 makes screen 16 move, thereby realizing the vibration of the surface of screen 16, while the bottom of screen 16 does not vibrate and rotates normally.

[0028] like Figure 1 and Figure 4 As shown, the reciprocating assembly 7 includes a rotating rod 701, a rotating disk 702, a drive column 703, and a drive frame 704. The drive frame 704 is fixedly connected to the end of the cleaning brush 6. The drive column 703 is fixedly connected to the bottom end of the rotating disk 702, and the drive column 703 is located away from the axis of the rotating disk 702. The drive column 703 is movably engaged with the inner side of the drive frame 704. The bottom end of the rotating rod 701 is fixedly connected to the top axis of the rotating disk 702. A support block 12 is fixedly connected to the outer side of the screen box 1. The rotating rod 701 passes through the support block 12, and the rotating rod 701 is movably connected to the support block 12.

[0029] The rotation of the rotating rod 701 causes the rotating disk 702 to rotate around the axis of the rotating rod 701, which in turn causes the drive column 703 to rotate around the axis of the rotating disk 702. Since the drive column 703 and the drive frame 704 are in movable cooperation, the cleaning brush 6 is driven to move back and forth, brushing off the fine particles attached to the surface of the screen 16, thus preventing fine impurities from accumulating inside the screen holes and affecting the screening of raw materials.

[0030] like Figure 1 and Figure 4 As shown, the drive assembly 8 includes a drive rod 801, a cam 802, a first conical wheel 803, and a second conical wheel 804. The drive rod 801 passes through the cam 802 and is fixedly connected to the cam 802. The first conical wheel 803 is fixedly connected to one end of the drive rod 801, and the second conical wheel 804 is fixedly connected to the top of the rotating rod 701. The first conical wheel 803 and the second conical wheel 804 mesh with each other. The surface of the cam 802 is in contact with the top surface of the bracket 503. A set of symmetrical fixing blocks 13 are fixedly connected to the top of the screen box 1. The drive rod 801 is movably connected to the opposite side of the fixing blocks 13. A servo motor 14 is fixedly connected to the outside of the screen box 1, and the output end of the servo motor 14 is fixedly connected to one end of the drive rod 801. A servo motor 15 is fixedly connected to the outside of the screen box 1, and the output end of the servo motor 15 is fixedly connected to the end of the rotating shaft of the control wheel 2.

[0031] Through the meshing of conical wheel 803 and conical wheel 804, the drive rod 801 can realize the rotation of cam 802 and the rotation of rotary rod 701, thereby realizing the vibration of screen 16 and the reciprocating movement of cleaning brush 6 at the same time, effectively vibrating and screening raw materials, keeping the screen holes of screen 16 unobstructed, and maintaining the screening effect of the entire screening device.

[0032] Working principle: In use, firstly, high-alumina castable is introduced into the screen box 1 through the feed pipe 9. The raw material falls onto the top surface of the screen 16. The servo motor 15 is started, driving the control wheel 2 to rotate inside the screen box 1, causing the screen 16 to rotate inside the screen box 1. The screen holes on the screen 16 screen the raw material. Smaller particles fall through the screen holes onto the guide plate 4 and slide down along the guide plate 4 into the discharge pipe 11 for discharge. Larger particles slide down along the screen. The material slides off the surface of screen 16 into the discharge pipe 10 and is discharged. During the raw material screening process, the servo motor 14 is started, driving the drive rod 801 to rotate in the screen box 1. The drive rod 801 drives the cam 802 to rotate synchronously. During the rotation of the cam 802, the support 503 is pressed downward, driving the roller 501 to move downward. Thus, the roller 501 presses the top of the screen 16. The roller 501 also rolls with the rotation of the screen 16. The roller 501 and the screen 16... As the surface of screen 16 moves downward, roller 502 moves downward as well. Roller 502 also rolls along with the surface of screen 16. The downward movement of roller 502 causes support 504 to move downward, compressing and shortening the folding spring 505. As cam 802 continues to rotate, the folding spring 505 pushes roller 501, roller 502, and screen 16 upward. This reciprocating motion vibrates the top surface of screen 16, causing the screen to fall onto the surface of screen 16. The raw materials can be fully sieved; while the drive rod 801 rotates, it drives the cone wheel 803 to rotate. Since the cone wheel 803 meshes with the cone wheel 804, the cone wheel 804 and the rotating rod 701 rotate synchronously, causing the rotating disk 702 to rotate around the axis of the rotating rod 701, and causing the drive column 703 to rotate around the axis of the rotating disk 702. Since the drive column 703 is in movable cooperation with the drive frame 704, it drives the cleaning brush 6 to move back and forth, brushing off the fine particles attached to the surface of the screen 16.

[0033] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
