Problems solved by technology
[0004] In order to make up for the deficiencies in the prior art, solve the problem that the nickel sulfate press filtrate obtained by the filter press contains more moisture, and the content of nickel sulfate without crystal water is less, and the existing recovery device is used for the nickel sulfate press filtrate. When recovering, the processing efficiency of these waters is low, and the invention proposes a battery-grade nickel sulfate filter press filtrate recovery device

Embodiment approach
[0026] As an embodiment of the present invention, the output shaft of the motor 41 is fixedly connected with the fan blade 10; when working, the motor 41 will drive the fan blade 10 to rotate after starting to work, and fan the water vapor inside the recovery bucket 2, so that the recovery The water vapor inside the barrel 2 flows out from the exhaust groove 51 .
[0027] Working principle: There is a wire inside the rotating shaft 44, and the electric heating rod 46 is connected to the external power supply through the wire. When the nickel sulfate solution is poured into the recovery bucket 2, the motor 41 is started, so that the motor 41 drives the No. 1 gear 42 to rotate, and then passes through the No. 1 gear. The meshing action between gear 42 and No. 2 gear 43 makes rotating shaft 44 start to rotate, and realizes the stirring of nickel sulfate solution, and electric heating rod 46 also has been stirred while nickel sulfate is heated, makes the nickel sulfate inside recov...

The invention belongs to the technical field of recovery devices, and relates to a filtrate recovery device of a battery-grade nickel sulfate filter press. The device comprises a base, a recovery barrel, a top plate and a stirring mechanism; the recycling barrel is fixedly connected to the top of the base; the top plate is fixedly connected to the top of the recycling barrel; the stirring mechanism is arranged in the recycling barrel; the stirring mechanism comprises a motor, a first gear, a second gear and a rotating shaft; the motor is fixedly connected to the top of the top plate; the first gear is arranged on an output shaft of the motor in a sleeving mode and fixedly connected with the output shaft of the motor; a cavity is formed in the top plate; and the first gear is located in the cavity. A nickel sulfate solution is fully stirred, the nickel sulfate solution is stirred while being heated by an electrical bar, so that the nickel sulfate solution in the recycling barrel is fully heated, water in the nickel sulfate solution can be quickly evaporated, meanwhile, crystal water in nickel sulfate molecules is lost, and the treatment efficiency of the water in the nickel sulfate solution is high.
Description
technical field [0001] The invention belongs to the technical field of recovery devices, in particular to a recovery device for the press filtrate of a battery-grade nickel sulfate filter press. Background technique [0002] Nickel sulfate is an inorganic substance. It exists in three ways, including anhydrous, hexahydrate and heptahydrate. Most of what we encounter in real life is hexahydrate, that is, there are six crystal waters in the molecule. Hexahydrate loses six crystal waters when heated to 103°C to obtain anhydrous. [0003] The nickel sulfate press filtrate obtained by the filter press contains more moisture inside, and the content of nickel sulfate without crystal water is small. However, when the existing recovery device reclaims the nickel sulfate press filtrate, the treatment of these water The efficiency is low, so the present invention provides a battery-grade nickel sulfate filter press filtrate recovery device. Contents of the invention [0004] In ord...
