Abstract
Description
Technical Field
[0001] This utility model belongs to the field of refractory furnace charge screening and iron removal technology, specifically a refractory furnace charge screening and iron removal device. Background Technology
[0002] The refractory charge screening and iron removal device is a piece of equipment used to screen and remove iron from refractory charges, aiming to improve the quality and purity of refractory charges and meet the requirements of different industrial production for refractory materials.
[0003] The specific design and structure of refractory charge screening and iron removal devices may vary depending on the manufacturer and application requirements, but generally they include the following key components: feed inlet and wire drawing die assembly, etc. The feed inlet is usually located at the top of the device and is the entrance for the refractory charge to enter the device. It is usually designed in the shape of a funnel to facilitate the smooth entry of the charge and to play a certain buffering role to prevent the charge from directly impacting the screening or iron removal components. The screen is the core component of the screening mechanism. Depending on the different particle size requirements of the refractory charge, screens of different mesh sizes and materials can be selected. The screen is usually set at an angle to facilitate the movement of the material towards the discharge port under the action of gravity, while improving screening efficiency.
[0004] Different production scenarios and products have different requirements for the particle size of refractory furnace materials. Existing refractory furnace material screening and iron removal devices can only screen a single specification, requiring multiple screenings, which increases time costs and cannot flexibly adapt to various production needs. During use, refractory furnace material particles are easily stuck on the screening plate. As the screen hole blockage worsens, the screening efficiency gradually decreases and cannot be maintained at a stable level. To ensure the normal operation of the device, it is necessary to frequently stop the machine to clean the screening plate, which not only wastes a lot of time but also reduces production efficiency and increases production costs. Summary of the Invention

This not only improves the degree of automation of production, but also reduces the interference of human factors on equipment operation, improves the stability and reliability of production, and also reduces the labor intensity of operators.
[0012] The advantages of this utility model are: the screening cylinder is equipped with a No. 1 screening chamber, a No. 2 screening chamber and a No. 3 screening chamber, and each chamber has screening plates of different specifications at the bottom. This multi-stage screening structure can screen refractory furnace materials multiple times, and can more accurately separate furnace materials of different particle sizes, thereby improving the screening efficiency and accuracy and meeting the requirements of different production for furnace material particle size.
[0013] The scraper on the auger shaft is equipped with a brush, and the brush is in contact with the No. 1 and No. 2 screening plates. During the rotation of the auger shaft, the scraper drives the brush to clean the screening plates, which can promptly remove refractory furnace material particles stuck in the screen holes, prevent screen hole blockage, ensure the normal operation of the screening plates, maintain stable screening efficiency, and reduce the time and labor costs of stopping the machine for cleaning due to screen hole blockage.

[0023] The screening cylinder 3 is provided with a first screening chamber 20. The bottom of the first screening chamber 20 is provided with a first screening plate 15. The side of the first screening plate 15 is provided with a second screening chamber 21. The bottom of the second screening chamber 21 is provided with a second screening plate 17. The side of the second screening plate 17 is provided with a third screening chamber 22.
[0024] During operation, in order to screen and remove iron from the refractory furnace charge, the refractory furnace charge enters the first screening chamber 20 inside the screening cylinder 3 through the feeding pipe 19. The stirring motor 11 is started, driving the auger shaft 12 to rotate. The three sets of auger blades 13 on the auger shaft 12 stir the refractory furnace charge in the first screening chamber 20, the second screening chamber 21, and the third screening chamber 22 respectively. Under the action of gravity, the refractory furnace charge of different particle sizes is screened in the first screening chamber 20, the second screening chamber 21, and the third screening chamber 22 respectively. The smaller particles of refractory furnace charge pass through the corresponding screening plate and enter the next screening chamber, while the larger particles of refractory furnace charge remain in the current screening chamber. Several electromagnets 14 on the inner wall of the screening cylinder 3 generate a magnetic field when energized, which adsorbs the magnetic substances in the refractory furnace charge, thereby realizing the separation of magnetic refractory furnace charge from non-magnetic refractory furnace charge.
[0025] The three sets of auger blades 13 are respectively installed in the first screening chamber 20, the second screening chamber 21 and the third screening chamber 22. The auger shaft 12 is provided with two scrapers 16, and the two scrapers 16 are provided with brushes 23. The two scrapers 16 are respectively installed on the side of the first screening plate 15 and the second screening plate 17, and the brushes 23 are designed to fit in close contact with the first screening plate 15 and the second screening plate 17.
[0026] During operation, in order to clean the No. 1 screening plate 15 and the No. 2 screening plate 17, the auger shaft 12 rotates, driving the two scrapers 16 and the brushes 23 on them to rotate together. The two scrapers 16 are respectively set on the sides of the No. 1 screening plate 15 and the No. 2 screening plate 17, and the brushes 23 are designed to fit closely to the No. 1 screening plate 15 and the No. 2 screening plate 17, so as to scrape off the refractory furnace material attached to the No. 1 screening plate 15 and the No. 2 screening plate 17, ensuring the smooth progress of the screening process.
[0027] The No. 1 screening chamber 20, the No. 2 screening chamber 21 and the No. 3 screening chamber 22 are all equipped with discharge pipes 18. The bottom of the No. 2 motor bracket 6 is equipped with a support column 9. The stirring motor 11, the regulating motor 7 and the electromagnet 14 are all connected to an external controller. The controller is used to control the start and stop of the stirring motor 11, the regulating motor 7 and the electromagnet 14.
[0028] During operation, in order to discharge the refractory furnace material after each screening stage, the operator controls the motor 7 to start via the controller. The transmission gear 8 and the driven gear 5 mesh to drive the rotating block 4 to rotate, which in turn causes the screening cylinder 3 to rotate around its own axis. The discharge pipe 18 set on the screening cylinder 3 is rotated and moved to the bottom of the device. After the refractory furnace material after each screening stage is discharged and cleaned through the discharge pipe 18, the electromagnet 14 is de-energized. The iron material attracted by the electromagnet 14 falls off the electromagnet 14 and is discharged through the discharge pipe 18.
[0029] Working principle: In order to screen and remove iron from refractory furnace materials, the refractory furnace materials enter the first screening chamber 20 inside the screening cylinder 3 through the feeding pipe 19. The stirring motor 11 is started, driving the auger shaft 12 to rotate. The three sets of auger blades 13 on the auger shaft 12 stir the refractory furnace materials in the first screening chamber 20, the second screening chamber 21, and the third screening chamber 22 respectively. Under the action of gravity, the refractory furnace materials of different particle sizes are screened in the first screening chamber 20, the second screening chamber 21, and the third screening chamber 22 respectively. The smaller particles of refractory furnace materials pass through the corresponding screening plates and enter the next screening chamber, while the larger particles of refractory furnace materials remain in the current screening chamber. Several electromagnets 14 on the inner wall of the screening cylinder 3 generate a magnetic field when energized, which adsorbs the magnetic substances in the refractory furnace materials, thereby realizing the separation of magnetic refractory furnace materials from non-magnetic refractory furnace materials.
[0030] In order to clean the No. 1 screening plate 15 and the No. 2 screening plate 17, when the auger shaft 12 rotates, it drives the two scrapers 16 and the brushes 23 on them to rotate together. The two scrapers 16 are respectively set on the sides of the No. 1 screening plate 15 and the No. 2 screening plate 17, and the brushes 23 are designed to fit closely to the No. 1 screening plate 15 and the No. 2 screening plate 17, so as to scrape off the refractory furnace material attached to the No. 1 screening plate 15 and the No. 2 screening plate 17, ensuring the smooth progress of the screening process.
[0031] In order to discharge the refractory furnace material after each screening stage, the operator controls the motor 7 to start through the controller. The transmission gear 8 and the driven gear 5 drive the rotating block 4 to rotate, which in turn causes the screening cylinder 3 to rotate around its own axis. The discharge pipe 18 set on the screening cylinder 3 is rotated and moved to the bottom of the device. After the refractory furnace material after each screening stage is discharged and cleaned through the discharge pipe 18, the electromagnet 14 is de-energized. The iron material attracted by the electromagnet 14 falls off the electromagnet 14 and is discharged through the discharge pipe 18.
