Description

Technical Field

[0001] This utility model relates to the field of nickel sulfate processing technology, specifically a nickel sulfate vacuum belt filter device. Background Technology

[0002] Nickel sulfate is an important inorganic compound with the chemical formula NiSO4. It usually exists in the form of crystalline hydrates, commonly in hexahydrate (NiSO4·6H2O) and heptahydrate (NiSO4·7H2O). It appears as green crystals or powder, is readily soluble in water, and slightly soluble in ethanol. Its preparation methods mainly include the dissolution of metallic nickel and the recycling of nickel-containing waste. Nickel sulfate can be produced by reacting metallic nickel with a mixture of sulfuric acid and nitric acid. Industrially, it is also often extracted from nickel-containing waste such as electroplating sludge and spent catalysts, and the product is obtained through leaching, purification, and crystallization processes. Nickel sulfate is a key raw material in modern industry, widely used in the electroplating industry as the main electrolyte for nickel plating, imparting corrosion resistance and decorative properties to metal surfaces. In the battery field, it is a core raw material for the cathode material of ternary lithium batteries. It is also used to prepare nickel catalysts, pigments, ceramic glazes, and trace element fertilizers in agriculture. It should be noted that nickel sulfate has a certain degree of toxicity; contact with skin or inhalation of dust may cause allergies, requiring protective measures. Its wastewater discharge must be strictly treated to avoid environmental pollution.

[0003] Currently, when processing nickel sulfate, a vacuum belt filter is required. When using a vacuum belt filter, a feed roller is installed at the feed inlet to help spread the suspension to be filtered evenly on the filter belt, thereby ensuring consistent filtration effect throughout the filtration process. However, when the feed roller squeezes the material to be processed, the material tends to adhere to the surface of the roller, affecting the subsequent use of the feed roller. Utility Model Content

[0029] Furthermore, a motor 11 is fixedly mounted on the rear surface of the first mounting plate 2 on the rear side. The output end of the motor 11 rotates through to the rear end of the feed roller 3, and the motor 11 is fixedly connected to the feed roller 3.

[0030] Furthermore, a U-shaped plate 12 is fixedly installed on the right end of the upper surface of the filter frame 1, and a cylinder 13 is fixedly installed on the upper surface of the U-shaped plate 12, with the lower end of the cylinder 13 extending through to the bottom of the U-shaped plate 12.
