Description

TECHNICAL FIELD

[0001] The application relates to the technical field of manganese sulfate production, in particular to a feeding and discharging equipment for high-purity manganese sulfate production. BACKGROUND

[0002] In the production process of high-purity manganese sulfate, the leaching process is one of the key links. The process needs to fully mix and react soft manganese ore and sulfuric acid to form the required leaching solution. At present, the equipment used for high-purity manganese sulfate production has some problems in feeding and discharging and mixing reaction that need to be solved.

[0003] In the existing production equipment, the conveying of soft manganese ore and the addition of sulfuric acid are usually carried out separately, and there is a lack of an integrated feeding and discharging system. The conveying of soft manganese ore usually adopts simple conveying devices such as conveyors or manual carrying, which not only has low efficiency, but also is difficult to ensure uniform conveying and precise control of soft manganese ore. At the same time, in the conveying process, the soft manganese ore may have the problem of uneven particle size, and the large-particle soft manganese ore directly enters the reaction box, which will affect the mixing effect and reaction efficiency of sulfuric acid.

[0004] For the addition of sulfuric acid, although some equipment can realize a certain degree of automatic addition, the output of the leaching solution after the completion of the leaching reaction is also an important link. The existing equipment often needs manual transfer in the output of the leaching solution, which not only has low efficiency, but also has safety hazards such as leakage in the transfer process, and it is also difficult to ensure the purity and quality stability of the leaching solution.

[0060] In one embodiment: refer to Figures 1-9 A feeding and discharging equipment, comprising a base 1, a top of the base 1 is fixedly installed with an electric heating mixing and stirring box 2. The top of the electric heating mixing and stirring box 2 is fixedly installed with a driving motor I 3, the output shaft of the driving motor I 3 extends into the electric heating mixing and stirring box 2, and a stirring and homogenizing frame 4 is fixedly installed at the end of the output shaft, which is used for mixing and stirring soft manganite and sulfuric acid. A feeding hole 10 is formed on one side of the top of the electric heating mixing and stirring box 2.

[0061] As Figure 9 shown, a spiral conveying mechanism is installed on one side of the top of the base 1, which is located on one side of the top of the electric heating mixing and stirring box 2 and communicates with the feeding hole 10. The spiral conveying mechanism is composed of a feeding box 6, a feeding guide pipe 7, a driving motor II 8, a feeding guide pipe 9, a feeding spiral rod 14 and a crushing assembly. The feeding box 6 is fixedly installed on one side of the top of the base 1, a feeding guide pipe 7 is fixedly penetrated through the inner wall of the bottom on one side of the feeding box 6, and a driving motor II 8 is fixedly installed on the top. The output shaft of the driving motor II 8 extends into the feeding box 6, and a feeding spiral rod 14 is fixedly installed at the end of the output shaft, and the bottom end of the feeding spiral rod 14 is rotatably connected with the inner wall of the bottom of the feeding box 6. A feeding guide pipe 9 is fixedly penetrated and installed on the inner wall of the top on the other side of the feeding box 6, one end of the feeding guide pipe 9 extends to the outside of the feeding box 6 and is connected with the crushing assembly, and the crushing assembly is installed on one side of the top of the electric heating mixing and stirring box 2 and communicates with the feeding hole 10.

[0062] As Figure 4 and Figure 6As shown, the crushing assembly includes a crushing box 5, a strip cutter 17, an electric push rod I 15 and a pressing plate 16. The crushing box 5 is fixedly installed on one side of the top of the electric heating mixing and stirring box 2 and communicates with the feeding hole 10. A plurality of strip cutters 17 are fixedly installed in the crushing box 5 at equal intervals. The strip cutters 17 cooperate to realize the screening of soft manganite. The electric push rod I 15 is fixedly installed on one side of the top of the crushing box 5. The output shaft of the electric push rod I 15 extends into the crushing box 5 and is fixedly installed with the pressing plate 16. The pressing plate 16 is in sliding contact with the inner wall of the crushing box 5. One end of the feeding conduit 9 extends into the crushing box 5 and is fixedly connected with the inner wall of one side of the crushing box 5. The soft manganite is fed into the feeding box 6 through the feeding conduit 7. The driving motor II 8 is started to drive the feeding screw rod 14 to rotate, thereby conveying the soft manganite upward. The soft manganite is conveyed into the crushing box 5 through the feeding conduit 9. The soft manganite falls downward through the gap between the adjacent two strip cutters 17.

The output shaft of the driving motor I 3 is also fixedly sleeved with the conical homogenizing disc 13 located below the dispersion homogenizing frame 11. The screened soft manganite falls into the homogenizing ring 12 through the feeding hole 10. When the output shaft of the driving motor I 3 rotates, the dispersion homogenizing frame 11 disperses the soft manganite. The conical homogenizing disc 13 rotates synchronously. The soft manganite falls on the conical homogenizing disc 13 and is dispersed and falls in the electric heating mixing and stirring box 2 under the action of centrifugal force, thereby avoiding material stacking.
