[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please refer to the following: Figures 1-3 ,in, Figure 1 A schematic diagram of the main cross-section of a preferred embodiment of the chromium ore powder preheating and drying device provided by this utility model; Figure 2 A front cross-sectional view of a preferred embodiment of the chromium ore powder preheating and drying device provided by this utility model; Figure 3 for Figure 2 The diagram shows an enlarged view of part A.

[0024] The chromium ore powder preheating and drying device includes: a drying box 1 with a partition net 2 fixedly installed; a hot air blower 3, which is fixedly installed on the drying box 1, and an air inlet pipe 4 is fixedly installed at the air outlet end of the hot air blower 3, extending into the drying box 1 and respectively arranged on both sides of the partition net 2 with the chromium ore powder; a filter box 5, which is fixedly installed on the drying box 1; an exhaust pipe 6, which is fixedly installed on the drying box 1, and the other end of the exhaust pipe 6 extends into the filter box 5; a collection box 7, which is slidably installed in the filter box 5, and a guide pipe 8 is fixedly installed in the collection box 7, the guide pipe 8 being slidably connected to the exhaust pipe 6; an exhaust pipe 9, which is fixedly installed on the filter box 5 for discharging filtered air; and a secondary filtration mechanism, which is arranged in the filter box 5 for secondary filtration of the chromium ore powder. The partition mesh 2 divides the interior of the drying chamber 1 into different areas, separating the hot air from the chromite powder on both sides. This prevents the chromite powder from directly contacting the hot air outlet, which would cause a large amount of dust to be emitted, thus reducing the amount of dust discharged with the gas and lowering the risk of raw material waste and environmental pollution. The hot air blower 3 is fixedly installed on the drying chamber 1, with its air inlet pipe 4 extending into the drying chamber 1 and positioned on both sides of the partition mesh 2, respectively, along with the chromite powder. The hot air blower 3 provides a stable supply of hot air, which is delivered to the drying chamber 1 through the air inlet pipe 4 to preheat and dry the chromite powder, ensuring the continuous drying process. The partition mesh 2 further optimizes the drying environment and reduces dust generation. The filter box 5 provides an independent space for filtering the exhaust gas, facilitating centralized treatment of dust-containing gas generated during the drying process. The exhaust pipe 6 guides the dust-containing gas from the drying chamber 1 into the filter box 5, allowing the gas to enter the subsequent filtration process. Collection box 7 is used to collect the filtered chromium ore powder dust. Guide pipe 8 guides the gas, allowing it to smoothly enter the filtration area within collection box 7. After sufficient powder is filtered out, collection box 7 can be removed for cleaning and chromium ore powder collection again. The filtered gas is discharged through exhaust pipe 9. At this point, the dust content in the gas is significantly reduced, meeting environmental emission requirements and reducing pollution to the surrounding environment. The secondary filtration mechanism further refines the gas after the initial filtration, ensuring more thorough removal of dust, greatly improving filtration efficiency, further reducing raw material waste and environmental pollution, and making the emitted gas cleaner and more environmentally friendly.

[0025] The secondary filtration mechanism includes a filter plate 10, a slide groove 11, and a slider 12. The filter plate 10 is slidably mounted on the filter box 5, the slide groove 11 is formed inside the filter box 5, and the slider 12 is fixedly mounted on the filter plate 10 and slidably mounted inside the slide groove 11. The filter plate 10 can perform secondary fine filtration on the gas that has undergone preliminary filtration, further intercepting residual fine dust particles in the gas, greatly improving the filtration effect. The combined use of the slide groove 11 and the slider 12 makes the installation and disassembly of the filter plate 10 more convenient, facilitating regular cleaning or replacement of the filter plate 10, ensuring that the secondary filtration mechanism can stably and efficiently perform its filtration function for a long time, and continuously reducing raw material waste and environmental pollution.

[0026] A slide rail 13 is fixedly installed on the filter box 5, and a sealing door 14 is slidably installed on the filter box 5, with the sealing door 14 slidably connected to the slide rail 13. The slide rail 13 provides a stable track for the sliding of the sealing door 14, allowing the sealing door 14 to open and close smoothly. When it is necessary to clean, maintain, or replace components such as the collection box 7 and filter plate 10 inside the filter box 5, the operator can easily slide the sealing door 14 to open it, and after the operation is completed, the sealing door 14 can be easily closed to seal the filter box 5. This is beneficial for the daily maintenance and management of the equipment, preventing dust and other impurities from entering the filter box 5 when not under maintenance, and ensuring the normal operation and filtration effect of the filtration system.

[0027] A limiting block 15 is fixedly installed on the sealing door 14, and the limiting block 15 slides into the drying chamber 1. An operating block 16 is fixedly installed on the sealing door 14. The design of the limiting block 15 ensures that the sealing door 14 can be accurately positioned when closed and plays a certain role in fixing it, preventing the sealing door 14 from being opened accidentally and ensuring the airtightness of the filter box 5. The operating block 16 allows the operator to manually operate the sealing door 14. When it is necessary to clean, maintain, or replace components such as the collection box 7 and filter plate 10 inside the filter box 5, the operator only needs to easily slide the sealing door 14 open by operating the block 16. After the operation is completed, the operator can easily close the sealing door 14 and seal the filter box 5, which facilitates the daily maintenance and management of the equipment and can also effectively prevent dust and other impurities from entering the filter box 5 when not under maintenance.

[0028] The drying chamber 1 is hinged to a support leg 17, and a drive motor 18 is fixedly mounted on the support leg 17. The output shaft of the drive motor 18 is fixedly mounted on the drying chamber 1. The support leg 17 provides a stable support foundation for the entire drying device, ensuring that the device remains stable during operation. By rotating the drive motor 18 forward and backward, the drying chamber 1 can be rotated around the hinge point at a certain angle. The operator can flexibly adjust the angle of the drying chamber 1 according to the characteristics of the chromite powder and the drying requirements, so that the chromite powder can be more evenly distributed and flowed within the drying chamber 1, further improving drying efficiency and quality.

[0029] A fixing plate 19 is fixedly installed between the supporting legs 17, and a spring 20 is fixedly installed on the fixing plate 19. The other end of the spring 20 is fixedly installed on the drying chamber 1. The spring 20 plays an important role in buffering and shock absorption in the device. When the drive motor 18 drives the drying chamber 1 to adjust the angle, or when the drying chamber 1 is subjected to external impact during operation, the spring 20 can absorb and release energy through its own elastic deformation, effectively reducing the shaking and vibration of the drying chamber 1, making the angle adjustment process more stable and smooth, avoiding damage to the internal parts of the device due to violent shaking, and extending the service life of the device.

[0030] A fixed frame 21 is fixedly installed on the drying chamber 1. A rotating shaft 22 is rotatably installed inside the drying chamber 1, and the rotating shaft 22 is rotatably mounted on the fixed frame 21. A stirring shaft 23 is fixedly installed on the rotating shaft 22, and the stirring shaft 23 slides in contact with the inner wall of the drying chamber 1. A protective cover 24 is fixedly installed on the drying chamber 1, and a rotary motor 25 is fixedly installed inside the protective cover 24. The output shaft of the rotary motor 25 is fixedly connected to the rotating shaft 22. The rotating shaft 22 is rotatably installed inside the drying chamber 1 and is rotatably mounted on the fixed frame 21, ensuring the stability of the rotating shaft 22 during operation. During the drying process, the stirring shaft 23 continuously stirs the chromite powder as the rotating shaft 22 rotates, allowing the chromite powder to be fully agitated within the drying chamber 1. This avoids local accumulation and uneven drying, significantly improving drying efficiency and further enhancing the drying quality of the chromite powder. The protective cover 24 provides excellent protection for the rotary motor 25, effectively preventing external dust, moisture, and other impurities from entering the rotary motor 25, protecting its normal operation and extending its service life. As the power source for the stirring shaft 23, the rotary motor 25 ensures that the stirring shaft 23 can continuously and efficiently stir the chromite powder, guaranteeing the smooth progress of the entire drying process.
