Description

Technical Field

[0001] This utility model relates to the field of crystal preparation technology, and in particular to a drying device for nickel sulfate production. Background Technology

[0002] Nickel sulfate production typically begins with nickel-bearing ore, commonly including nickel sulfide ore and laterite nickel ore. The ore needs to be crushed and ground for subsequent chemical treatment. The treated ore is then contacted with a sulfuric acid solution, where the sulfuric acid reacts with the nickel to produce nickel sulfate. The leaching solution contains nickel sulfate and other impurities, which are then purified. The purified nickel sulfate solution needs to undergo crystallization to convert the nickel sulfate in the solution into solid particles. This step is usually carried out at low temperatures to promote the formation of nickel sulfate crystals. The crystallized nickel sulfate crystals then need to be dried to remove residual moisture.

[0003] Existing nickel sulfate crystal drying equipment involves introducing the crystals into a drying chamber and drying them through the combined action of heating and stirring mechanisms. However, during the stirring and drying process, the crystals in existing equipment tend to disperse, causing them to be scattered throughout the drying chamber. This makes it difficult to achieve rapid discharge of the crystals, reducing work efficiency. Therefore, a new type of drying equipment for nickel sulfate production is needed. Utility Model Content

[0004] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide a drying equipment for nickel sulfate production. This equipment can solve the problem that in the process of stirring and drying, the crystals are stirred and dispersed, resulting in the crystals being dispersed inside the drying chamber and making it difficult to achieve rapid discharge of the crystals.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drying device for nickel sulfate production, comprising a protective shell and a crystal stirring mechanism. The crystal stirring mechanism includes a device support, an electric push rod, a container, a motor, a rotating shaft, stirring blades, a sealing plate, a placement groove, and a filter screen. The device support is fixedly connected to the bottom of the protective shell. Multiple electric push rods are fixedly connected to the surface of the device support. The container is slidably connected inside the protective shell and fixedly connected to the electric push rods. The motor is fixedly connected to the top of the protective shell. The rotating shaft is fixedly connected to the output end of the motor. The stirring blades are fixedly connected to the bottom of the rotating shaft. The sealing plate is fixedly connected to the bottom of the stirring blades. The placement groove is opened on the surface of the container. The filter screen is fixedly connected inside the container.

[0006] Preferably, the placement groove is shaped like an inverted frustum, and the sealing plate is slidably connected to the bottom of the placement groove.

[0007] Preferably, the surface of the container is provided with an air outlet, which is connected to the interior of the placement slot through a filter screen.

[0010] Preferably, a dustproof net is fixedly connected to the surface of the drying shell, and multiple cooling fans are fixedly connected to the inside of the drying shell.

[0011] Preferably, a feed pipe is fixedly connected to the top of the protective shell, and a cover is threaded onto the surface of the feed pipe.
