Description

Technical Field

High-quality basic nickel carbonate can be used in the electronics industry and catalyst industry. In addition, basic nickel carbonate is also widely used in electroplating, electrocasting, porcelain glaze pigments, etc.

[0003] The basic nickel carbonate precipitant is generally sodium carbonate or ammonium carbonate (or ammonium bicarbonate). When ammonium carbonate (or ammonium bicarbonate) is used as the precipitant, the raw materials are cheap and the obtained nickel carbonate has fine particle size, but the nickel conversion rate is not high, the mother liquor must be recovered, and the nickel carbonate has a low density. When sodium carbonate is used as the precipitant, the raw materials are easy to obtain and cheap, the nickel salt conversion rate is high, the cost is low, and it has good economic benefits.

[0004] During the preparation process of nickel carbonate, the wet nickel carbonate precipitate needs to be scattered and dried. In the invention patent with publication number CN117346513A, a double-axis drying and scattering device was invented. However, after the material entered the drying and scattering device, the double-axis scattering device failed to spread the material evenly inside the device, resulting in unsatisfactory drying effect and reduced drying efficiency.

[0005] In the invention patent with the authorization announcement number CN116358277B, an online drying device for feed processing is invented.

However, when the material slides down, the material is easy to enter the suction pipe, thereby increasing the loss of the material.

The intelligent drying box for drying nickel carbonate according to claim 6, characterized in that: The transmission mechanism comprises a driven pulley (33) fixedly mounted on a connecting shaft (14), a driving pulley (34) fixedly mounted on the driving shaft (32), and the driving pulley (34) is connected to the driven pulley (33) via a belt.

8. An intelligent drying box for drying nickel carbonate according to any one of claims 1 to 5, characterized in that: An arc-shaped baffle (35) is provided at the bottom of the feed channel (12), and the arc-shaped baffle (35) is used to block the bottom of the feed channel (12). A reciprocating swing mechanism is provided on the connecting shaft (14), and the reciprocating swing mechanism is connected to the arc-shaped baffle (35). The reciprocating swing mechanism is used to drive the arc-shaped baffle (35) to swing back and forth in the feed channel (12), so that materials can be transported into the machine body (10) in a timely and quantitative manner.

9. The intelligent drying box for drying nickel carbonate according to claim 8, characterized in that: The reciprocating swing mechanism comprises a driving half gear (36) fixed on a connecting shaft (14); a driven half gear (37) is rotatably connected to the bottom of the feed channel (12) via a shaft; a connecting block (38) is provided at one end of the driven half gear (37) facing the arc-shaped baffle (35); the connecting block (38) is connected to the arc-shaped baffle (35); and the driven half gear (37) rotates via the connecting block (38); A reset member is provided at the bottom of the feed channel (12), the reset member being connected to the driven half gear (37), and the reset member being used to reset the driven half gear (37), thereby enabling the driven half gear (37) to continuously mesh with the driving half gear (36).

10. The intelligent drying box for drying nickel carbonate according to claim 9, characterized in that: The reset element is a torsion spring (39) connected to the bottom of the feed channel (12), and the torsion spring (39) is connected to the driven half gear (37).
