Description

Technical Field

[0001] The utility model relates to the field of ore processing devices, in particular to a dust treatment device for gold-zinc ore processing. Background Art

[0002] Gold-zinc ore is a mineral rich in the metallic element zinc, which contains a small amount of galena, pyrite, and a small amount of calcite. Zinc is a metal element with a wide distribution of resources in nature. It mostly exists in the state of sulfide. The main zinc-containing mineral is sphalerite, and there are also small amounts of oxide ores such as gold-zinc ore, willemite, hemimorphite, and hydrozincite. Gold has a low abundance in the earth's crust and has properties such as sulfur affinity, copper affinity, iron affinity, and high melting point. It combines with zinc in the sulfide state to form gold-zinc ore.

[0003] Gold and zinc ore needs to go through multiple processing steps in mines and refineries. During the processing, a large amount of dust will be generated in the air. If the dust is not purified, it will pollute the environment and affect the health of workers. On the other hand, it will also cause waste of minerals in the dust. The existing gold and zinc ore dust treatment device is covered by a conical cover above the device that is easy to raise dust during ore processing, and then sucked into the dust filter bag through the pipeline for collection, and then the collected dust is centrally processed by the staff. In the dust removal process, the dust enters the dust extraction pipeline because of the collision and friction between the particles during the movement, and the collision and friction between the dust particles and the inner wall of the dust extraction pipeline. The dust particles with static electricity will be adsorbed (agglomerated) on the inner wall of the dust extraction pipeline. After the dust extraction is completed, the dust adhering to the inner wall of the pipeline or the dust left in the pipeline that is not sucked into the dust filter bag will fall down and form a new dust mist, which is not convenient for the recovery and treatment of dust, resulting in waste of materials. The new dust mist will be inhaled by the staff, affecting the health of the staff. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-5 As shown, this embodiment provides a dust treatment device for gold-zinc ore processing, comprising a dust extraction cone hood 1 and a dust extraction pipe 2; one end opening of the dust extraction pipe 2 is connected to the small-diameter end of the top of the dust extraction cone hood 1; wherein:

[0022] The dust handling device is a dust inlet component and a dust conveying component in a bag pulse dust collector. A plurality of material receiving cone covers 3 arranged up and down are installed in the dust extraction cone cover 1, and there is a gap between two adjacent material receiving cone covers 3. The upper material receiving cone cover 3 of the two adjacent material receiving cone covers 3 covers the lower material receiving cone cover 3, and the bottom periphery of the lowest material receiving cone cover 3 is connected to the surrounding inner walls of the dust extraction cone cover 1, and a material receiving groove is formed between the outer wall of the lowest material receiving cone cover 3 and the bottom inner wall of the dust extraction cone cover 1, and the lowest material receiving cone cover 3 and the bottom of the dust extraction cone cover 1 can be detachably connected by bolts; such as Figure 2 The small-diameter opening at the top of the uppermost material receiving conical cover 3 is smaller than the opening size of the dust extraction pipe 2.

[0023] A sealing structure is also installed in the dust extraction cone hood 1 to seal the top opening of the topmost material receiving cone hood 3. The sealing structure includes a rotating plate 4, and the rotating plates 4 are two, and the two rotating plates 4 are similar to a double-door structure, such as Figure 2As shown. The rotating plate 4 is rotatably installed in the dust extraction cone hood 1 through the rotating shaft 5. The dust extraction cone hood 1 is also equipped with a driving mechanism for rotating the rotating plate 4 in the dust extraction cone hood 1. When the dust and particles in the dust extraction pipe 2 fall down, they hit the rotating plate 4. The particles and dust mist can only come out through the gap between the receiving cone hood 3. However, since the receiving cone hood 3 is covered on the same surface, the particles will fall along the inclined surface of the receiving cone hood 3. When the particles want to come out of the gap, they need to overcome the effect of gravity and move upward. However, when they are not affected by external forces, it is difficult to move upward. This can reduce the falling of particles and facilitate the centralized recovery and treatment of metal mineral particles in ore dust. The driving mechanism includes a protective box 6, a cylinder 7 and a transmission assembly; the protective box 6 is installed on the outer wall of the dust extraction cone hood 1, and the cylinder 7 is installed on the protective box 6. The output shaft of the cylinder 7 can drive the rotating shaft 5 to rotate through the transmission member. The transmission assembly includes a rotating rod 8, a sliding shaft 9 and a transmission rod 10. The rotating rod 8, the sliding shaft 9 and the transmission rod 10 are all located in the protective box 6, which can protect one end of the rotating rod 8, reduce the external dust adhering to its surface, and reduce the occurrence of running jams. One end of the rotating rod 8 is connected to one end of the rotating shaft 5, the sliding shaft 9 is connected to one side of the rotating rod 8, and the transmission rod 10 is connected to the output shaft of the cylinder 7. The transmission rod 10 is provided with an active sliding groove that slides with the sliding shaft 9. The sliding direction of the sliding shaft 9 in the active sliding groove is arranged perpendicular to the conveying direction of the output shaft of the cylinder 7. The specific structure and position are as follows: Figure 3 , Figure 4 shown.

[0024] When the dust extraction work for the dust generated in the production of gold and zinc ore is stopped, the cylinder 7 will work, and the output shaft of the cylinder 7 will work to drive the transmission rod 10 to move up and down. When the transmission rod 10 moves up and down, the inner wall of the movable slide groove acts on the sliding shaft 9, and the sliding shaft 9 slides in the movable slide groove, and the sliding shaft 9 drives the rotating rod 8 and the rotating shaft 5 to rotate, and then the rotating shaft 5 drives the rotating plate 4 to rotate. When the two rotating plates 4 rotate to the top surface of the uppermost receiving cone cover 3, the top opening of the receiving cone cover 3 is blocked, and the dust and particulate matter in the dust extraction pipe 2 falls down. The particles will fall on the rotating plate 4 and the inclined surface of the uppermost receiving cone cover 3, and will slide down along the inclined surface of the receiving cone cover 3 to reach the receiving trough for collection. Since the receiving cone cover 3 is a cover on top of another to form a tower-like structure, the particles will hardly fall through the gaps between the receiving cone covers 3. The staff will regularly remove the lowermost receiving cone cover 3 to clean up the accumulated particles, which can facilitate the staff to centrally process the particles and extract the metal minerals in the particles.
