Description

TECHNICAL FIELD

[0001] The utility model relates to rare earth ore technical field especially ion ore impurity edulcoration process pool and cantilever crane. BACKGROUND

[0002] Rare earth ore mainly exists in the form of mineral in the crust, and rare earth exists in the form of ionic compound in the mineral lattice. The current new mode of rare earth ore mining is in-situ leaching process, which is to inject high-concentration cation solution (magnesium sulfate solution) into the mine without damaging the vegetation on the surface of the mining area, without excavating the topsoil and ore. The rare earth ions flow to the bottom of the mine under the action of the water pressure and gravity, and are finally collected.

[0003] Usually, these collected rare earth ion solutions (also known as rare earth mother liquor) need to be precipitated and collected by an edulcoration process pool, including impurity precipitation and rare earth ion precipitation. The solution needs to be boiled before collection to accelerate the exchange of metal ions of the ore product with the added compound, forming a colloidal ore product and precipitating. Since the current edulcoration process pool is large in size, related equipment is needed to stir the solution. At present, most of the edulcoration process pools are provided with stirrers at the bottom to stir the solution to flow and boil. The equipment installation is complex, and a large power is required. In addition, gas is delivered through a vertical pipe inserted into the solution to make it boil. This requires piping at multiple locations, and a lifting device is needed to realize the lifting of the pipe. The required structure and equipment are more, and the overall layout is relatively complex.

[0004] The existing patent document CN220099140U discloses a mine edulcoration process pool to solve the problems of complex equipment installation and large power required for stirring when boiling the rare earth mother liquor. The vertical pipe delivery gas method involves more equipment, and the overall layout is relatively complex. After the precipitation work is completed, the supernatant in the edulcoration process pool needs to be drained. One end of the water pipe can be connected to a water pump. The speed and height of the water pipe lowering are controlled according to the extraction of the supernatant and the height of the ion ore impurity precipitate. The supernatant on the top of the ion ore impurity precipitate in the edulcoration process pool is extracted layer by layer. The disturbance to the ion ore impurity precipitate can be reduced when the supernatant is extracted. In the patent document CN220099140U, the motor that pulls the water pipe up or down is close to the bending part of the water pipe, and the angle of the pull rope connecting the motor and the water pipe is too small. The motor needs to output a large power, and the requirement for the motor is high.

[0005] The existing patent document CN216807875U also discloses a cantilever crane provided with an adjustable mechanical limiting structure. Since the power of the electric hoist is small, it is difficult to perform hoisting operations with heavy weight.

[0031] Further improvement of the above-mentioned embodiment, in combination Figure 2Also included is a lifting ring 27 fixed to the left end of the cross arm 11, the hook 24 is a pulley hook, and the end of the steel wire rope 23 is connected to the lifting ring 27 after winding around the pulley of the hook 24. Preferably, a sunshade cover 21 is also included, the winch 2 is fixed to the stand column 1 through a support 22, the sunshade cover 21 is installed above the support 22 and above the winch 2 through a connecting rod, and is used for shading and rainproofing the winch 2.

[0032] In the preferred embodiment, when the steel wire rope between the hook 24 and the second pulley 26 is in a vertical state, the water inlet port of the drain pipe 4 is pulled to a predetermined position, at which time the drain pipe water inlet port 41 is above the mother liquor level of the impurity removal process tank.
