Description

Technical Field

[0001] The utility model relates to the technical field of matte processing, and more specifically to a matte granulation and drying device. Background Art

[0002] The copper smelting process generally involves first smelting the selected copper concentrate to obtain matte, and then transferring the matte into a blowing furnace for blowing to obtain blister copper.

[0003] At present, in the process of quenching and granulating copper matte, a drying device is needed to dry the copper matte particles. However, the drying efficiency of the drying device during use and the feeding and discharging efficiency of the copper matte particles are poor, which greatly reduces the production efficiency of the drying device.

[0004] For example, a matte granulation drying device disclosed in announcement number CN216011496U has a drain outlet connected to one side of the water collection tank; a rotating screw shaft is movably fixed in the middle of the drying tank, and the lower end of the rotating screw shaft is connected to a supporting grid through an internal threaded seat.

[0005] It can be seen from the above-mentioned public scheme that when the matte particles are dried, the matte particles need to be transported to the inside of the feed port by a screw, and then fall onto the supporting grid to stand still. This process takes a long time and the drying efficiency is reduced, thereby reducing the working efficiency of the drying device. Utility Model Content

[0027] Example 2

[0028] See also Figure 1-3The matte granulation drying device comprises a drying tank 1. The inner and outer surfaces of the drying tank 1 are both provided with heat-insulating layers to reduce the heat loss rate inside the drying tank 1. A drying cylinder 2 is fixedly sleeved in the middle position of the drying tank 1. A hot air pipe 22 is provided at one end of the drying cylinder 2. A hot air blower is provided at one end of the hot air pipe 22 to facilitate the hot air to be blown into the drying cylinder 2. An air inlet chamber 21 is connected to one end of the hot air pipe 22. A blowing pipe 23 is fixedly sleeved on the inner wall of the air inlet chamber 21.
