Description

Technical Field

[0001] This utility model relates to the field of metal raw material processing technology, specifically to a copper matte spiral humidification device. Background Technology

[0002] Matte is a very important intermediate product in pyrometallurgical processes, specifically referring to the molten copper sulfide produced during copper smelting.

[0003] In the metal smelting and processing process, matte is an intermediate product. During the process, it is cooled and crushed before being processed in subsequent production. During the processing, it is necessary to adjust the humidity of the crushed matte powder. Existing technology usually uses existing metal ore crushing and humidification equipment to adjust the humidity of the matte powder. The existing matte powder needs to be controlled at a humidity of about 8% for subsequent processing requirements.

[0004] Existing humidification equipment uses a pair of spiral conveyors driven by a motor, and then sprays humidifying air directly above the spiral conveyors. The spiral conveyors stir the powdered raw materials to accelerate the absorption of atomized humidifying air and improve humidification mixing efficiency. However, existing humidification equipment has difficulty controlling the humidity level, which affects subsequent metal processing and leads to a decline in the quality of molded products.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 3 This utility model provides a technical solution:

[0023] Example 1: A copper matte spiral humidification device includes a humidification frame 1. A pair of spiral conveying components are arranged in parallel and spaced apart inside the humidification frame 1. The pair of spiral conveying components are driven to rotate by a motor 2. The spiral conveying components include a rotating shaft 3, a large spiral 4 and a small spiral 5. The end of the rotating shaft 3 is connected to the output end of the motor 2. The large spiral 4 and the small spiral 5 are fixed on the outer wall of the rotating shaft 3. The outer diameter of the large spiral 4 is larger than the outer diameter of the small spiral 5.

[0024] By setting up spiral conveyors with different outer diameters, different stirring forces and conveying efficiencies can be achieved for the copper matte powder.

[0025] The humidifying frame 1 has an open top. The upper opening of the humidifying frame 1 is provided with a first humidifying cover 6, a reduced diameter cover 8, and a second humidifying cover 7. The positions of the large spiral 4 and the small spiral 5 correspond to the first humidifying cover 6 and the second humidifying cover 7, respectively. A sampling component is provided on the reduced diameter cover 8.

[0026] By setting the first humidifying cover 6 and the second humidifying cover 7, the humidification of the humidifying frame can be adjusted in stages. With the help of the sampling component, the copper matte powder after the initial humidification is sampled and tested. Based on the test results, the humidification intensity of the second humidifying cover 7 is intelligently adjusted, thereby precisely controlling the humidity of the copper matte powder and ensuring that the humidity of the copper matte is around 8%.

[0027] Example 2: Based on Example 1, both the first humidifying cover 6 and the second humidifying cover 7 are provided with multiple sets of humidifying nozzles 9 linearly distributed and facing the upper end of the inner cavity of the humidifying frame 1. The multiple sets of humidifying nozzles 9 are connected to an atomizing humidifying device through an air pipe 10. The two sides of the humidifying frame 1 are respectively provided with a feed inlet and a discharge outlet. The feed inlet is located at the end near the first humidifying cover 6. The first humidifying cover 6 is provided with at least one set of humidifying nozzles 9 located above the feed inlet. The discharge outlet is located below the end of the small spiral 5. There is a gap between the large spiral 4 and the small spiral 5, and the top of the gap is directly opposite the diameter reduction cover 8.

[0028] The atomizing humidification equipment is a common device for preparing atomized airflow, which will not be described in detail. The atomized humidifying airflow is delivered to the humidification nozzle 9 through the air pipe 10. The humidification nozzle 9 releases the atomized humidifying airflow at the upper end of the inner cavity of the humidification frame 1. With the spiral stirring and conveying of the spiral conveying component, the absorption of the atomized humidifying airflow by the copper matte powder is accelerated, the atomization humidification efficiency is improved, and the uniformity of humidification is also improved.

[0029] Example 3: Based on Example 2, the upper inner cavity of the reduced diameter cover 8 is configured as a lifting inner cavity 12. The lower end of the lifting inner cavity 12 is provided with a conical hole 11 communicating with the inner cavity of the humidifying frame 1. A piston 17 is elastically installed in the lifting inner cavity 12. The upper end of the piston 17 is provided with a scale rod 14 extending to the outer side of the upper end of the lifting inner cavity 12. A limit cover 16 is provided at the upper end of the lifting inner cavity 12. A spring 18 is sleeved on the lower end of the scale rod 14. The upper end of the scale rod 14 slides through the limit cover 16. The spring 18 is pressed between the limit cover 16 and the piston 17. An upper frame 13 is provided on the upper outer wall of the reduced diameter cover 8. A telescopic pressure rod 15 is provided vertically downward at the upper end of the upper frame 13. The free end of the telescopic pressure rod 15 is directly opposite the scale rod 14.

[0030] By setting a limiting cover 16 to prevent the piston 17 from falling off, and by using a reducing diameter cover 8 to reduce the outline size of the humidifying frame 1, the raw material after the initial humidification is conveyed by the large spiral 4 at the front end. Due to the reduced conveying size, the raw material gathers and squeezes against each other at the position of the reducing diameter cover 8. The squeezing removes air, increases the mutual penetration of water in the raw material, and improves the humidification efficiency and uniformity. At the same time, the raw material rises along the conical hole 11 and squeezes the piston 17, causing the piston 17 to rise and drive the scale rod 14 to rise. The spring 18 is compressed. The height of the scale rod 14 reflects the internal pressure, which makes it easy to adjust the feed rate and control the pressure.

[0031] Example 4: Based on Example 3, the sampling assembly includes a sampling screw rod 20 and a sampling transverse groove 19. A sampling transverse groove 19 is provided laterally on one side wall of the lifting inner cavity 12. A sampling screw rod 20 driven by rotating a handle is provided in the sampling transverse groove 19. A sampling port 21 is provided through the lower end of the sampling transverse groove 19. The sampling port 21 is located at the end away from the lifting inner cavity 12, and the sampling port 21 is perpendicularly connected to the sampling transverse groove 19.

[0032] As the piston 17 rises, the raw material enters the sampling transverse groove 19. The sampling screw 20 is driven to sample the copper matte powder after the initial humidification at this position. By detecting the humidity, the humidification efficiency of the subsequent second humidification cover 7 is adjusted. When the humidity is insufficient, the jetting efficiency of the second humidification cover 7 is adjusted according to the difference.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
