Description

Technical Field

[0001] This utility model relates to the field of iron concentrate processing technology, specifically to a pressurized iron concentrate dehydration device. Background Technology

[0002] Iron concentrate is an important raw material for steel production. Its dehydration treatment is a key step in the mineral processing and metallurgical process. Iron concentrate dehydration treatment refers to removing water from iron concentrate through physical or mechanical methods to reduce its moisture content and meet the requirements of subsequent processing or transportation.

[0003] Traditional dewatering devices typically dewater iron concentrate by directly squeezing and dewatering it using a combination of extrusion rollers and conveyor belts. However, when the iron concentrate slurry is poured directly into the conveyor belts through the feed inlet, excessive feeding speed can cause the slurry to accumulate too thickly on the belts, preventing timely drainage of moisture and resulting in incomplete dewatering. This leads to reduced dewatering efficiency, unstable moisture content in the finished product, and negatively impacts subsequent processing or transportation. Utility Model Content

[0025] The present invention will now be described in further detail with reference to the accompanying drawings.

[0026] In order to dehydrate the iron concentrate slurry under pressure, combined with... Figure 1 and attached Figure 3A pressurized iron concentrate dewatering device includes four fixed plates 1 at the four corners, with the two fixed plates 1 connected together by support plates 2. It also includes a first conveyor filter belt 3 and a second conveyor filter belt 4. The first conveyor filter belt 3 is horizontally arranged between the fixed plates 1, and the second conveyor filter belt 4 is inclined between the fixed plates 1. There is a certain angle between the first conveyor filter belt 3 and the second conveyor filter belt 4, and they work together to perform a squeeze dewatering operation on the iron concentrate slurry. A first drive roller 7 and a second drive roller 8 are rotatably connected between the two sets of fixed plates 1 from top to bottom. The first drive roller 7 located at the top is connected by the second conveyor filter belt 4. The lower second drive roller 8 is connected via the first conveyor filter belt 3. One end of the first drive roller 7 is connected to the output end of the first motor 5, and one end of the second drive roller 8 is connected to the output end of the second motor 6. The first motor 5 drives the second conveyor filter belt 4 to rotate, and the second motor 6 drives the first conveyor filter belt 3 to rotate. Since the first conveyor filter belt 3 and the second conveyor filter belt 4 are at a certain angle and their rotation directions are opposite, the iron concentrate slurry is continuously driven forward. The cooperation of the continuously rotating first drive roller 7 and the second drive roller 8 on one side can directly perform pressure dewatering operation on the iron concentrate slurry.

[0027] To facilitate material cutting, combined with the attached Figure 1 The feed inlet 12 is fixedly connected between the fixed plates 1 on one side. The bottom end of the feed inlet 12 extends between the first conveyor filter belt 3 and the second conveyor filter belt 4. It is used to deliver iron concentrate slurry to the first conveyor filter belt 3. Through the feed inlet 12, iron concentrate slurry can be continuously delivered directly to the first conveyor filter belt 3 and follow the first conveyor filter belt 3 forward.

[0028] During the dewatering process, the iron concentrate slurry in the feed inlet 12 tends to accumulate on the first conveyor filter belt 3, failing to distribute evenly on the filter belt, combined with the attached... Figure 3 and attached Figure 4The feed inlet 12 is provided with a material control assembly for easy adjustment of the feeding speed; the material control assembly includes a rotating shaft 14 and a baffle 13; the rotating shaft 14 is rotatably disposed in the feed inlet 12, and the baffle 13 is fixedly connected to the rotating shaft 14; the material control assembly also includes a worm gear 15 and a worm 17; the worm gear 15 is disposed at one end of the rotating shaft 14 extending outside the feed inlet 12, and a pair of connecting plates 16 are provided on one side of the feed inlet 12, the worm 17 is rotatably connected between the connecting plates 16 and meshes with the worm gear 15, and a handle 18 is provided at one end of the worm gear 15 extending outside the connecting plates 16. Rotating the handle 18 drives the worm gear 17 to rotate continuously, and the worm wheel 15 meshing with the worm gear 17 rotates accordingly, which in turn drives the rotating shaft 14 to rotate. The baffle 13 rotates accordingly, and the tilt angle of the baffle 13 can be flexibly adjusted. This not only allows the slurry to fall evenly along the gap between the baffle 13 and the feed port 12, but also allows for flexible adjustment of the feeding speed. This is suitable for iron concentrate slurries of different consistency, so that the iron concentrate slurry is evenly distributed on the first conveyor filter belt 3, avoiding accumulation or uneven distribution, and facilitating subsequent dewatering operations.

[0029] To facilitate the unified collection of dehydrated iron concentrate slurry, combined with... Figure 2 and attached Figure 3 The receiving structure is located beside a fixed plate 1 on one side and is used to collect the dehydrated iron concentrate. The receiving structure includes scrapers 10 and a receiving box 11. Two concave plates 9 are arranged in pairs between the fixed plates 1 on one side. Two scrapers 10 are fixedly mounted on the concave plates 9, and the bottom ends of the two scrapers 10 are in contact with the first conveyor filter belt 3 and the second conveyor filter belt 4, respectively. The receiving box 11 is placed directly below the scrapers 10. The scrapers 10 can directly scrape off the dehydrated iron concentrate adhering to the first conveyor filter belt 3 and the second conveyor filter belt 4, causing it to fall directly into the receiving box 11. The structure is simple and easy to implement.

[0030] In specific implementation of this utility model:

[0031] First, the iron concentrate slurry is poured directly into the feed inlet 12. The iron concentrate slurry falls continuously onto the first conveyor filter belt 3 along the feed inlet 12. The first conveyor filter belt 3 and the second conveyor filter belt 4 are at a certain angle and rotate in opposite directions, driving the iron concentrate slurry forward continuously. The cooperation of the first drive roller 7 and the second drive roller 8 rotating on one side can directly perform pressure dewatering operation on the iron concentrate slurry.

[0032] With the assistance of scraper 10, the dehydrated iron concentrate slurry can be directly scraped off from the first conveyor filter belt 3 and the second conveyor filter belt 4, causing it to fall directly into the receiving box 11. The structure is simple and easy to implement.

[0033] During use, turning the handle 18 drives the worm gear 17 to rotate continuously, and the worm wheel 15 meshing with the worm gear 17 rotates accordingly, which in turn drives the rotating shaft 14 to rotate. The baffle 13 rotates accordingly, and the tilt angle of the baffle 13 can be flexibly adjusted. This not only allows the slurry to fall evenly along the gap between the baffle 13 and the feed port 12, but also allows for flexible adjustment of the feeding speed. This is suitable for iron concentrate slurries of different thicknesses, ensuring that the iron concentrate slurry is evenly distributed on the first conveyor filter belt 3, avoiding accumulation or uneven distribution, and facilitating subsequent dewatering operations.
