Description

Technical Field

[0001] This utility model relates to the field of raw material processing technology for zirconium-alumina electrofused bricks, specifically a zirconium-alumina electrofused brick raw material screening machine. Background Technology

[0002] Zirconium-alumina fused bricks are refractory products made from industrial alumina powder and selected zircon sand, with a ZrO2 content of 33%-45%. Zirconium-alumina fused bricks are mainly used in glass industry tank furnaces, glass electric furnaces, steel industry chutes, and sodium silicate industry furnaces, etc., which are high-temperature and erosion resistant refractory materials. In the production process, the raw materials of zirconium-alumina fused bricks need to be screened, which requires a special zirconium-alumina fused brick raw material screening machine.

[0003] Most existing zirconium corundum electrofused brick raw material screening machines use vibrating motors to vibrate the screen to achieve screening, which has the advantages of reliable operation.

[0004] Existing zirconium-alumina electrofused brick raw material screening machines have the following problems: the screening effect is not good enough; when zirconium-alumina electrofused brick raw materials need to be separated quickly, the screening efficiency is low because the screen inclination cannot be adjusted; when zirconium-alumina electrofused brick raw materials need to be separated for a long time, multiple screenings are required because the screen inclination cannot be adjusted. Therefore, we propose a zirconium-alumina electrofused brick raw material screening machine. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-6This embodiment provides a technical solution: a zirconia-corundum electrofused brick raw material screening machine, including a shell 3, an adjustable screen 1 inside the shell 3, a guide plate 2 on the left side inside the shell 3, the guide plate 2 being located at the bottom left of the screen 1, which can better drop the screened raw material into the designated position, reducing the labor intensity of workers and improving work efficiency; it also includes a control switch group 5, the rear surface of the control switch group 5 being fixedly connected to the front surface of the shell 3, the input end of the control switch group 5 being electrically connected to an external power source, which can freely adjust the motor running state; it also includes casters 6, the casters 6 being evenly fixedly connected to the four ends of the lower surface of the shell 3, which can move and improve work efficiency; and it also includes a screen adjustment mechanism 9.

[0025] Screen adjustment mechanism 9 includes a threaded rod 91, an adjusting slider 92, a worm gear 93, and a worm wheel 94. Slide grooves are respectively provided on the right side of the front and rear inner walls of the outer casing 3. The adjusting slider 92 is slidably connected between the two slide grooves. The upper end of the adjusting slider 92 is rotatably connected to a dovetail block via a pin. A dovetail slide groove is provided on the right side of the bottom surface of the screen 1. The dovetail block is slidably connected to the dovetail slide groove. The threaded rod 91 is rotatably connected to the bottom wall of the outer casing 3. The upper end of the threaded rod 91 is threadedly connected to the middle of the adjusting slider 92. An adjusting groove is provided on the bottom wall of the outer casing 3. The worm gear 93 is rotatably connected inside the adjusting groove. The threaded rod 91 extends into the interior of the adjusting groove. It is equipped with a worm gear 94, and the worm 93 is meshed with the worm gear 94. The screen inclination can be quickly adjusted to speed up the screening efficiency while ensuring screening quality. For those that need to be separated for a long time, the inclination can be adjusted to ensure that the screen has enough time to screen to ensure quality. By holding the rotating rod to rotate the rotating wheel 7, the rotating wheel 7 drives the worm 93, the worm 93 drives the worm gear 91 to rotate, and the worm gear 91 drives the threaded rod 91 to rotate. By adjusting the slider 92 to slide up and down in the groove, the slider 92 drives the dovetail block to slide and avoid the dovetail groove, so that the screen 1 can change the inclination angle with the transmission shaft 10 as the center.

[0026] The system includes a drive shaft 10 and a vibration motor 4. The drive shaft 10 is rotatably connected to the left side between the front and rear inner walls of the outer casing 3. The outer surface of the drive shaft 10 is fixedly connected to the left side of the bottom surface of the screen 1. The vibration motor 4 is located on the bottom surface of the screen 1. The output end of the control switch group 5 is electrically connected to the input end of the vibration motor 4, which can provide fixation for the screen 1 when it moves. The system also includes a locking mechanism 8, which includes a pull rod 81, a locking block 82, and a spring 83. An adjustment port is provided on the right side of the front side of the outer casing 3. The locking block 82 is slidably connected to the inside of the adjustment port. The left side of the adjustment slider 92 has evenly distributed locking slots. The locking block 82 engages with the locking slots located on the same horizontal plane. The left outer surface of the locking block 82 is flush with the left inner wall of the adjustment port. A spring 83 is fixedly connected to the worm gear 93. A pull rod 81 is fixedly connected to the front outer surface of the locking block 82. The front end of the pull rod 81 passes through the adjustment port and can provide locking. Before screening, the pull rod 81 is pulled to the left. The pull rod 81 drives the locking block 82 to slide to the left in the adjustment port. At this time, the spring 83 retracts, and the locking block 82 separates from the locking slot located on the same horizontal plane, releasing the adjusting slider 92. After adjustment, the pull rod 81 is released. At this time, the spring 83 releases the compression force, causing the right end of the locking block 82 to move towards the locking slot located at the same horizontal height on the left side of the adjusting slider 92 until it is engaged. It also includes a rotating wheel 7. The rear end of the rotating wheel 7 is fixedly connected to the front end of the worm gear 93. The front end of the rotating wheel is provided with a rotating rod, which makes the adjustment easier and improves the work efficiency.

[0027] The working principle of the zirconium-alumina electrofused brick raw material screening machine provided by this utility model is as follows: When using the zirconium-alumina electrofused brick raw material screening machine, first pour the zirconium-alumina electrofused brick raw material into the feed inlet of the outer shell 3, and at the same time turn on the corresponding switch on the control switch group 5 to turn on the vibration motor 4. The vibration motor 4 drives the screen 1 to vibrate, thereby causing the screen 1 to screen the zirconium-alumina electrofused brick raw material. After screening, the large particles of zirconium-alumina electrofused brick raw material fall into the guide plate 2, and the small particles of zirconium-alumina electrofused brick raw material fall into the lower interior of the outer shell 3 and are screened out through the discharge port on the left. The screen position can be adjusted before screening. Before screening, first pull the pull rod 81 to the left. The pull rod 81 drives the locking block 82 to slide to the left in the adjustment port. At this time, the spring 83 contracts, the locking block 82 separates from the locking slot located on the same horizontal plane, and the adjusting slider 92 is released. By holding the rotating rod, the rotating wheel 7 is rotated. The rotating wheel 7 drives the worm 93, the worm 93 drives the worm wheel 91 to rotate, and the worm wheel 91 drives the threaded rod 91 to rotate. Under the action of the adjusting slider 92 sliding up and down in the slide groove, the adjusting slider 92 drives the dovetail block to slide and avoid the dovetail slide groove, so that the screen 1 can change the tilt angle with the transmission shaft 10 as the center. After the movement is completed, the pull rod 81 is released. At this time, the spring 83 releases the compression force, so that the right end of the locking block 82 moves to the locking slot located on the same horizontal height on the left side of the adjusting slider 92 until it is locked, thereby achieving the purpose of adjusting the screen 1.

[0028] It is worth noting that the control switch group 5 disclosed in the above embodiments is provided with a control button corresponding to the vibration motor 4 and used to control its switch. The vibration motor 4 is a PT-MVE miniature AC vibration motor (aluminum alloy).
