This product is black with a slight silver-gray color, has a metallic luster, feels slippery to the touch, and is insoluble in water. Molybdenum disulfide is an important solid lubricant, mainly because sulfur has a strong adhesion ability to metals, which can make molybdenum disulfide adhere well to the metal surface and always play a lubricating function; due to its stable chemical properties, it still has good lubrication function under high temperature and high vacuum conditions; therefore, molybdenum disulfide powder is used as a solid lubricant and is widely used in the lubrication industry.

[0003] At present, most of the existing molybdenum disulfide production is obtained by leaching molybdenum concentrate with hydrochloric acid to remove iron, leaching with hydrofluoric acid to remove silicon, vacuum filtration, washing with deionized water, drying and crushing. However, the above methods are not ideal for removing iron content, which affects production efficiency. Utility model content:

[0006] The heating device includes a heating interlayer sleeved on the outer surface of the reaction tank, a water inlet pipe is welded to one end of the outer surface of the heating interlayer, the end of the water inlet pipe away from the heating interlayer is connected to the electric heater, the electric heater is fixed to one end of the outer surface of the insulation layer by bolts, the insulation layer is sleeved on the outer surface of the heating interlayer, the outer surface of the insulation layer away from the top of the electric heater is connected to the water tank through a water pipe, the other end of the outer surface of the insulation layer is welded to a water outlet pipe, and one end of the water outlet pipe extends to the interior of the heating interlayer.

[0007] Furthermore, the air outlet device includes an air outlet pipe welded on the top plate, a top cover is welded on the top of the air outlet pipe, one end of the top of the top cover is connected to the cover plate by a hinge, a T-block is movably connected to the other end of the inner surface of the top cover, the T-block is connected to the cylinder by bolts, and the output end of the cylinder is movably connected to the bottom of the cover plate through a connecting block.

[0008] Furthermore, both ends of the inner surface of the top cover away from the T-block are movably connected with connecting rods, one end of the connecting rod away from the top cover is connected to the support rod through a connecting rod, and one end of the support rod away from the connecting rod is movably connected to the bottom of the cover plate.

[0037] Embodiment 2

[0038] like Figure 1-7 As shown, this embodiment is obtained by describing in detail the technical features such as the air outlet device 7 on the basis of the embodiment 1. The remaining technical features are the same as those of the embodiment 1, and the similarities are not repeated here. The difference between this embodiment and the embodiment 1 is that: the end of the top of the top plate 2 away from the stirring motor 3 is connected to the pressure detector 17 by bolts, the model of the pressure detector 17 is YNXC, and the pressure detector 17 is electrically connected to the controller 88. The other end of the top of the top plate 2 away from the stirring motor 3 is equipped with an air outlet device 7, and the air outlet device 7 includes an air outlet pipe 71 welded to the top plate 2, and a top cover 72 is welded on the top of the air outlet pipe 71. One end of the top of the top cover 72 is connected to the cover plate 76 by a hinge 18, and a T-block 73 is movably connected to the other end of the inner surface of the top cover 72. The T-block 73 is connected to the cylinder 74 by bolts, and the cylinder 74 is connected to the controller 8 8 is electrically connected, and the output end of the cylinder 74 is movably connected to the bottom of the cover plate 76 through the connecting block 75. In order to facilitate the movement of the cover plate 76, the two ends of the inner surface of the top cover 72 away from the T-block 73 are movably connected with connecting rods 77, and the end of the connecting rod 77 away from the top cover 72 is connected to the support rod 79 through a connecting rod 78, and the end of the support rod 79 away from the connecting rod 78 is movably connected to the bottom of the cover plate 76. In order to ensure the sealing between the top cover 72 and the cover plate 76, a sealing strip 14 is fixedly connected to the inner surface of the top cover 72. When the pressure detector 17 detects that the air pressure in the tank is too high, the controller 88 starts the cylinder 74 to work, and the self-expansion of the cylinder 74 further drives the cover plate 76 to open from the top cover 72, thereby discharging the air pressure inside the reaction tank 1, thereby balancing the air pressure inside the reaction tank 1 and avoiding danger caused by the high air pressure inside the reaction tank 1.

[0039] The overall technical solution formed by the above embodiments is used as follows:

[0040] Personnel add hydrochloric acid: auxiliary agent: molybdenum concentrate into the reaction tank 1 according to the mass ratio of 0.8-5:0.1-0.3:1. First, place the hydrochloric acid in the reaction tank 1, and then add the auxiliary agent to the reaction tank 1. The nitrate ion or hypochlorite ion in the auxiliary agent participates in dissolving the acid-insoluble matter containing a very small amount of iron and enters the reaction solution, while the other chloride ion reacts with the iron ion in the solution to form a stable complex in the presence of hydroxyethylidene diphosphonic acid (HEDP), so that the iron ions in the solution are reduced, the potential of the iron ions is reduced, and the dissolution equilibrium of the system is broken. The nitrate ion or hypochlorite ion further dissolves the acid-insoluble matter containing a very small amount of iron, and then enters the next dissolution and complexation cycle. The two anions form an ideal ion synergistic effect, converting the acid-insoluble matter in the molybdenum concentrate into an acid-soluble iron-containing stable complex, so as to achieve the purpose of deep iron removal. The stirring motor 3 is used to form a uniform solution of the two, and then the molybdenum concentrate is added. The mass ratio of hydrochloric acid: auxiliary agent: molybdenum concentrate is 0.8-5: 0.1~0.3:1, wherein the reaction temperature is 40~95℃, the reaction time is 1~12 hours, and the volume concentration of hydrochloric acid is 30%. At this time, the stirring motor 3 drives the stirring shaft 4 to rotate, so that the stirring rod 5 rotates synchronously with the stirring shaft 4. The setting of the stirring vertical rod 6 further improves the stirring efficiency of the stirring rod 5. At the same time, the controller 88 enables the electric heater 83 to work, and the electric heater 83 heats the water in the water pipe 85. The heated water flows into the heating interlayer 81 through the water inlet pipe 82, so that the temperature of the reaction tank 1 reaches the reaction temperature, thereby improving the efficiency of hydrochloric acid iron removal and reducing cost waste. When the pressure detector 17 detects that the air pressure in the tank is too high, at this time, the controller 88 enables the cylinder 74 to start working, and the self-expansion of the cylinder 74 further drives the cover plate 76 to open from the top cover 72, thereby discharging the air pressure inside the reaction tank 1, thereby balancing the air pressure inside the reaction tank 1 and avoiding danger caused by the high air pressure inside the reaction tank 1.
