Technical Field

[0001] The utility model relates to the field of iron ore mining, in particular to a impurity removal device for iron ore mining. Background Art

[0002] As the main raw material for steel manufacturing, with the improvement of the quality and demand of steel, the quality and demand for iron ore also increase. Therefore, it is necessary to remove impurities from the mined iron ore. In order to improve the quality of iron ore, it is also necessary to spray desulfurizing agent on the surface of iron ore for desulfurization treatment. The existing iron ore desulfurization treatment usually directly sprinkles the desulfurizing agent on the surface of iron ore manually. This not only cannot ensure that the desulfurizing agent is evenly sprinkled on the surface of iron ore, but also has the problem of high desulfurizing agent consumption. Therefore, an impurity removal device for iron ore mining is needed to solve the above problems.

This impurity removal device for iron ore mining equipment solves the problem that the contact between the dephosphorization liquid and the ore surface in the prior art is insufficient, resulting in poor desulfurization effect.

[0004] This patent stirs and mixes the desulfurizing agent with iron ore through three stirring shafts and stirring blades in the stirring barrel. The spraying device of this device is arranged at the central position of the stirring box. When the iron ore is stirred, it is easy to fall from above the spraying device and damage the spraying device, resulting in device damage. At the same time, this device discharges materials through the diameter difference at the full rear end of the stirring barrel, and there is a problem of low discharging efficiency. Summary of the Invention

[0005] The purpose of the utility model is to provide an impurity removal device for iron ore mining, which has the advantages of high mixing efficiency of desulfurizing agent and iron ore, good impurity removal effect, long service life, and can adjust the inclination angle of the device to improve the discharging efficiency and speed, thus improving the practicability.

[0006] The purpose of the present utility model is to provide a impurity removal device for iron ore mining, which includes a base and a mixing barrel. The left and right sides of the bottom of the mixing barrel are sequentially rotatably connected with an electric telescopic column and a support frame. The bottom end of the electric telescopic column is rotatably connected with the base, and the bottom of the support frame is fixedly connected with the base. A mixing cavity is opened in the mixing barrel, a feeding port is opened at the top of the mixing barrel, and a discharging port is opened on one side of the mixing barrel. Both the feeding port and the discharging port are communicated with the mixing cavity. A mixing component is rotatably arranged in the mixing cavity. A liquid storage tank is fixedly arranged on the top of the base, a spraying tank is fixedly arranged on the top of the mixing barrel, a spraying component is fixedly arranged in the spraying tank, and the liquid storage tank is fixedly connected with the spraying component.

[0007] Further, the mixing component includes a driving motor and a rotating shaft. The driving motor is fixedly arranged on one side of the mixing barrel. One end of the rotating shaft is rotatably arranged on the inner wall of one side of the mixing cavity, and the other end passes through the mixing cavity and is fixedly connected with the output end of the driving motor. A spiral fan blade is fixedly arranged on the surface of the rotating shaft.

[0008] Further, a negative pressure water pump is fixedly arranged on the top of the liquid storage tank. The water inlet end of the negative pressure water pump extends deep into the inner bottom of the liquid storage tank. The water outlet end of the negative pressure water pump is fixedly connected with a conveying pipe, and the other end of the conveying pipe is fixedly connected with the spraying component.

[0009] Further, the spraying component includes a spraying pipe. The spraying pipe is fixedly connected with the water outlet end of the conveying pipe.

[0012] Further, a liquid outlet is fixedly arranged on one side of the mixing barrel away from the discharging port, and a solenoid valve is installed on the liquid outlet.

[0013] The working principle and usage principle of the present utility model are as follows: Through the cooperation of the electric telescopic column and the support frame, when feeding is required, the electric telescopic column shortens the extending distance so that the discharging port end of the mixing barrel is lower than the other end. Then, the spiral fan blade in the mixing component is used to discharge the mixed iron ore. At the same time, before feeding and when evenly mixing the iron ore and the desulfurizing agent, the extending distance of the electric telescopic column is increased, so that the discharging port end is higher than the liquid outlet, which is convenient for discharging the used desulfurizing agent from the mixing barrel, and at the same time avoids the iron ore and the desulfurizing agent from flowing out from the discharging port during mixing. The spraying component is arranged on the top of the mixing barrel, which avoids damage to the spraying pipe and the spraying nozzles during the mixing and stirring of the iron ore.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows: The device is convenient to adjust the inclination angle of the mixing barrel through the setting of the electric telescopic column, and can discharge desulfurizing agent and iron ore from the discharge port and liquid outlet of the mixing barrel respectively according to the usage situation to meet the rapid feeding, improving the impurity removal efficiency of the device.

Detailed Description of the Invention

[0021] According to Figure 1 and Figure 2As shown in the figure, an impurity removal device for iron ore mining includes a base 1 and a mixing barrel 2. The left and right sides of the bottom of the mixing barrel 2 are sequentially rotatably connected to an electric telescopic column 4 and a support frame 3. The bottom end of the electric telescopic column 4 is rotatably connected to the base 1, and the bottom of the support frame 3 is fixedly connected to the base 1. A trapezoidal block 31 is sleeved at the bottom of the support frame 3, and the trapezoidal block 31 is fixedly connected to the support frame 3 and the base 1 respectively. A mixing cavity is formed in the mixing barrel 2. An inlet 6 is provided at the top of the mixing barrel 2, and an outlet 5 is provided on one side of the mixing barrel 2. Both the inlet 6 and the outlet 5 communicate with the mixing cavity. A liquid outlet 11 is fixedly provided on the side of the mixing barrel 2 away from the outlet 5, and a solenoid valve 111 is installed on the liquid outlet 11. A mixing assembly 7 is rotatably arranged in the mixing cavity. A liquid storage tank 10 is fixedly provided on the top of the base 1, and a spray tank 8 is fixedly provided on the top of the mixing barrel 2. A spray assembly 9 is fixedly provided in the spray tank 8, and the liquid storage tank 10 is fixedly connected to the spray assembly 9.

[0022] The top and bottom ends of the electric telescopic column 4 are respectively rotatably connected to the mixing barrel 2 and the base 1. The bottom of the support frame 3 is fixedly connected to the base 1, and the stability of the support frame 3 is improved by the trapezoidal block 31. The top of the support frame 3 is rotatably connected to the mixing barrel 2. By controlling the extension and retraction of the electric telescopic column 4, one end of the mixing barrel 2 can be tilted upward or downward. When it is necessary to mix iron ore and desulfurizer, the height of the electric telescopic column 4 is increased so that the end of the outlet 5 of the mixing barrel 2 is higher than the end of the liquid outlet 11, avoiding the spillage of iron ore and desulfurizer from the outlet 5 during mixing. At the same time, after the iron ore is evenly mixed, the solenoid valve 111 is controlled to open the liquid outlet 11, so that the desulfurizer can be directly discharged from the liquid outlet 11, eliminating the need to separate the iron ore and desulfurizer subsequently, improving the efficiency of iron ore treatment. The desulfurizer can be added to the liquid storage tank 10, and the desulfurizer in the liquid storage tank 10 is sprayed out from the spray tank 8 at the top of the mixing barrel 2 through the spray assembly 9, so as to be evenly sprayed on the surface of the iron ore in the mixing barrel 2. Then, the desulfurizer is evenly mixed on the surface of the iron ore by the rotation and stirring of the mixing assembly 7, enhancing the impurity removal effect of the iron ore, and the spray tank 8 is arranged at the top of the mixing barrel 2 to prevent damage to the spray assembly 9 by the iron ore during mixing.

[0023] According to Figure 3 and Figure 5 As shown in the figure, the mixing assembly 7 includes a driving motor 71 and a rotating shaft 72. The driving motor 71 is fixedly arranged on one side of the mixing barrel 2. One end of the rotating shaft 72 is rotatably arranged on the inner wall of one side of the mixing cavity, and the other end passes through the mixing cavity and is fixedly connected to the output end of the driving motor 71. A spiral fan blade 73 is fixedly arranged on the surface of the rotating shaft 72, and a through hole 731 is formed in the spiral fan blade 73.

[0024] The drive motor 71 controls the rotation shaft 72 to rotate in the mixing chamber. The diameter of the spiral fan blade 73 is smaller than that of the mixing chamber. While the rotation shaft 72 rotates, the spiral fan blade 73 arranged on its surface is used to mix the iron ore and the desulfurizer. Through holes 731 are formed in the spiral fan blades 73 to prevent the iron ore from failing to move between each spiral fan blade 73, thereby reducing the mixing efficiency.

[0025] According to Figure 4 As shown, a negative pressure water pump 102 is fixedly arranged at the top of the liquid storage tank 10. The water inlet end of the negative pressure water pump 102 extends deep into the inner bottom of the liquid storage tank 10. The water outlet end of the negative pressure water pump 102 is fixedly connected to a delivery pipe 101. The other end of the delivery pipe 101 is fixedly connected to the spraying assembly 9. The spraying assembly 9 includes a spraying pipe 91, and the spraying pipe 91 is fixedly connected to the water outlet end of the delivery pipe 101. The spraying pipe 91 is fixedly arranged in the spraying box 8. A plurality of spraying nozzles 92 can be arranged, and the plurality of spraying nozzles 92 are fixedly installed at equal intervals at the bottom of the spraying pipe 91.

[0026] An opening is arranged at the bottom of the spraying box 8, and the opening of the through hole 731 communicates the spraying box 8 and the mixing chamber. During use, the negative pressure water pump 102 pumps out the desulfurizer in the liquid storage tank 10 and transports it to the spraying pipe 91 through the delivery pipe 101. The desulfurizer is sprayed into the mixing chamber by the plurality of spraying nozzles 92 at the bottom of the spraying pipe 91. The spraying pipe 91 and the spraying nozzles 92 are both arranged in the spraying box 8 to prevent damage to the spraying pipe 91 and the spraying nozzles 92 when the iron ore and the desulfurizer are mixed, extend the service life of the spraying assembly 9, and also prevent the iron ore slag from blocking the spraying nozzles 92.
