Description

Technical Field

[0001] The utility model specifically relates to the technical field of wet germanium concentrate processing, in particular to a pre-drying treatment device and equipment for setting the device. Background Art

[0002] At present, in the existing concentrate production process, especially in the production link of wet germanium concentrate, the drying process is necessary. The moisture content of the general wet germanium concentrate is 50% on average. In the existing technology, the wet germanium concentrate is generally filtered by a filter press and then directly dried by a microwave drying equipment to remove a large amount of moisture contained therein.

[0003] At present, a Chinese utility model with a publication number of CN207163104U discloses a pre-drying treatment device for wet germanium concentrate. The utility model relates to a pre-drying treatment device for wet germanium concentrate, including a pre-drying mechanism and an exhaust hood, which is installed above the pre-drying mechanism; the pre-drying mechanism includes a heating panel, a pre-drying box, a plurality of steam nozzles and a steam trap group, the heating panel is arranged above the pre-drying box, the plurality of steam nozzles are arranged at intervals inside the pre-drying box, and the steam trap group is connected to the bottom of the pre-drying box. The utility model can pre-dry the wet germanium concentrate, reduce the drying cost of the wet germanium concentrate, and facilitate the subsequent drying treatment and storage of the germanium concentrate.

[0004] According to the above patent, the applicant has found that although the existing wet germanium concentrate pre-drying treatment device can reduce the drying cost of the wet germanium concentrate and facilitate the subsequent drying treatment and storage and preservation of the germanium concentrate, it uses a steam nozzle to pre-dry the wet germanium placed on the heating panel, and then the water vapor generated by the drying is sucked by the exhaust gas treatment mechanism through the exhaust hood. In this process, the water vapor generated by the drying has a certain amount of heat. When the exhaust hood is partially drawn out, it will cause partial loss of internal heat. Although the interior of the exhaust hood maintains a negative pressure environment, the lost heat still needs to be replenished, which will increase the steam consumption. Therefore, a pre-drying treatment device is proposed to solve the above-mentioned problems. Utility Model Content
