During the drying process, powder is easily scattered, resulting in low collection rate and increased cost. Symmetrically arranged fans are prone to airflow collision, causing powder to contaminate the inside of the fans, shortening the equipment life and reducing the overall drying effect.

[0021] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.
[0022] like Figure 1 - Figure 5 As shown, the rapid drying device for metallurgical auxiliary materials includes a primary filter box 1, a secondary filter box 2, and a tertiary filter box 3 for rapid screening of metallurgical auxiliary materials in sequence. A control valve 4 and a guide hopper 5 for conveying metallurgical auxiliary materials are provided between the primary filter box 1, the secondary filter box 2, and the tertiary filter box 3. Each of the primary filter box 1, the secondary filter box 2, and the tertiary filter box 3 is equipped with a screening component 6 for dispersing the metallurgical auxiliary materials. A drying temperature control module 7 for rapid drying of the screening component 6 is provided on the side of the primary filter box 1, the secondary filter box 2, and the tertiary filter box 3. Through the series design of the tertiary filter boxes 3, combined with the rotation and dispersing function of the screening component 6, multi-stage fine processing of metallurgical auxiliary materials is achieved, effectively solving the problem of easy powder dispersion in traditional devices.
[0023] Please see Figure 2 - Figure 4 In this embodiment, a protective box 101 is integrally formed in the middle of the primary filter box 1, the secondary filter box 2, and the tertiary filter box 3. A circular box 102 for processing metallurgical auxiliary materials corresponding to the screening components 6 is integrated inside the primary filter box 1, the secondary filter box 2, and the tertiary filter box 3. The circular box 102 and the protective box 101 are integrally formed (material: Q235 carbon steel, wall thickness 3mm) to reduce the thermal bridge effect. The protective box 101 is covered with a heat insulation sleeve 103. A heat-conducting plate for the drying temperature control module 7 is installed on the side wall of the circular box 102. A display screen 104 is installed on the primary filter box 1, the secondary filter box 2, and the tertiary filter box 3. Each filter box is independently equipped with a drying temperature control module 7. The heat-conducting plate and the temperature sensor (model: PT100, accuracy ±0.1℃) are linked to achieve temperature gradient control (150℃ for primary, 120℃ for secondary, and 90℃ for tertiary) to avoid the material from overheating and clumping.
[0024] Please see Figure 3- Figure 4 In this embodiment, the control valve 4 has symmetrically arranged closing plates at its bottom, and an adjusting shaft 402 is provided at the center of the closing plates. One end of the adjusting shaft 402 is connected to a signal module 401. The signal module 401 includes a battery box, an indicator light, and a signal device that are electrically connected to each other. The sieving assembly 6 includes a rotating shaft 601, and connecting plates 605 are connected to both ends of the rotating shaft 601. Several sets of sieve cylinders 604 are arranged circumferentially around the rotating shaft 601. An extension frame 609 is fixedly connected between the sieve cylinders 604 and the rotating shaft 601. One end is connected to a connecting shaft 606, and a fixing sleeve 608 is fitted on the connecting shaft 606. One end of the connecting shaft 606 is connected to a drive motor 607. The drive motor 607 drives the connecting shaft 606 and the rotating shaft 601 to rotate the screen cylinder 604. The screening component 6 adopts a curved frame 611 and a transmission column 614 design. The rotating shaft 601 (material: 304 stainless steel) drives the screen cylinder 604 (screen hole diameter 0.5mm) to rotate. Combined with the scraper plate 603 (material: wear-resistant ceramic) scraping the screening trough, it prevents material blockage.
[0025] Please see Figure 4 - Figure 5 In this embodiment, the sieve cylinder 604 is provided with several sets of separation grooves 610 circumferentially. Several sets of sieve plates 602 are circumferentially fixed near the edge of the two sets of connecting plates 605 (the spacing between the sieve plates 602 is 2mm, optimized based on the particle size distribution of metallurgical auxiliary materials (D50=1.5mm), balancing sieve efficiency and throughput). Shovel plates 603 are fixed to the outside of the sieve plates 602. A sieve groove is formed between the two sets of sieve plates 602. Several sets of curved frames 611 are circumferentially arranged at the outer end of the rotating shaft 601. Several sets of conduction columns 614 corresponding to the curved frames 611 are provided at the center of the rotating shaft 601. One end of the conduction column 614 is connected to a control board 613. The outer end of the control board 613 is electrically connected to a lithium battery pack 612. The drying temperature control module 7 includes an electrically connected electronic control box, a temperature sensor, a heater, a wireless module, and a battery box. The drying temperature control module 7 integrates a heater. The device consists of a PTC ceramic heating element (500W) and a wireless module (model: ESP32, operating frequency band 2.4GHz). The protective box 101 is externally covered with a silicone heat insulation sleeve 103 (5mm thick, thermal conductivity 0.03W / m·K) to reduce heat loss and prevent damage to the control module from high temperatures. The temperature data is monitored in real time through the control box (including the control screen 701: resolution 800×480). Hot air circulation is achieved in combination with the ventilation slots 702 (5mm in diameter). The control screen 701 is installed in the middle of the control box, and several sets of ventilation slots 702 are distributed on the control box. The control valve 4 closing plate is driven by the signal module 401 (including lithium battery pack 612: rated voltage 3.7V, capacity 2000mAh) to drive the adjustment shaft 402 to achieve precise opening and closing, avoiding the powder contamination problem caused by the counter-current of traditional fans.
[0026] Metallurgical auxiliary materials enter through the inlet of the primary filter box 1. The drive motor 607 (model: 57BLDC, rated torque 1.2N·m) drives the rotating shaft 601 to rotate through the connecting shaft 606. The separation groove 610 (diameter 1mm) on the screen cylinder 604 and the screen plate 602 (spacing 2mm) work together to break up the agglomerated materials into powder.
[0027] The shovel plate 603 (angle 45°) scrapes the inner wall of the screening tank to prevent material from adhering. The screened material enters the secondary filter box 2 through the guide hopper 5. The substandard material is intercepted by the closing plate (material: 304 stainless steel, thickness 2mm) and re-screened.
[0028] The electrical control box of the drying temperature control module 7 receives the temperature sensor signal, controls the output power of the heater, and conducts heat evenly to the inside of the circular box 102 through the heat conduction plate (material: aluminum alloy 6061, thickness 3mm). The wireless module transmits the temperature data to the PLC control system, automatically adjusts the opening angle of the ventilation slot 702 (0°-90°) to maintain the stable temperature inside the chamber, and at the same time discharges moisture.
[0029] When the material in the three-stage filter box 3 reaches the preset dryness level, the signal module 401 triggers the closing plate to open, and the material is discharged through the control valve 4.
[0030] If material accumulates in a certain stage of the filter box, the conduction column 614 (material: brass, diameter 8mm) drives the rotating shaft 601 to rotate in the opposite direction through the control board 613 (powered by the lithium battery pack 612) to assist in clearing the material.
[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
