[0002] Crushing of rare earth ores is one of the key steps in the rare earth element extraction process. However, during the crushing process, a large amount of fine dust will be generated due to the destruction of the internal structure of the ore, which not only poses a threat to the health of on-site workers, but may also cause environmental pollution and increase the difficulty of subsequent mineral processing. Traditional crushing devices often ignore or are only equipped with simple dust removal facilities, making it difficult to effectively control dust emissions. Therefore, it is particularly important to develop a rare earth ore crushing device that can both efficiently crush and have advanced dust removal functions.

[0003] In the prior art, dust reduction is generally carried out by atomization dust removal, and dust reduction is carried out by spraying at the discharge port of the ore crusher. However, the spray device in the prior art has a simple structure, and mainly realizes the movement of water mist by the pressure during the spraying process, so that the water mist can contact with the dust to capture the dust. Due to the limited pressure of the water mist, the dust can easily rush out of the water mist and escape outward, affecting the dust reduction effect. Utility Model Content

[0025] Embodiment: A rare earth ore crushing device

[0026] like Figure 1-3 As shown, a rare earth ore crushing device, the specific structure of which includes:

[0027] A cone crusher body 1 is provided with a feed port 2 at the upper end of the cone crusher body 1, a discharge port 3 at the lower end of the cone crusher body 1, an upper crushing wall and a lower crushing wall for extrusion crushing are installed in the cone crusher body 1, a first lower hopper 4 is fixedly installed on the upper end of the feed port 2, a plurality of evenly distributed sonic dust removal components are fixedly installed on the outer periphery of the first lower hopper 4 through a bracket, and ultrasonic atomizing nozzles 5 are respectively fixedly installed in the sonic dust removal components.

[0028] The sonic dust removal assembly includes a cylindrical cavity 6, the outer periphery of the cylindrical cavity 6 is fixedly connected to the outer side of the first lower hopper 4, a sonic generator 7 is fixedly installed at the lower end of the inner wall of the cylindrical cavity 6, and the sonic generator 7 is electrically connected to a power supply. An exhaust channel 8 with a fan-shaped structure is integrally fixedly installed on the side of the cylindrical cavity 6 facing the first lower hopper 4, an ultrasonic atomizing nozzle 5 is fixedly installed in the exhaust channel 8, and the drain outlet of the ultrasonic atomizing nozzle 5 faces the center of the first lower hopper 4, and a water inlet pipe 9 is fixedly installed at one end of the ultrasonic atomizing nozzle 5, and the water inlet pipe 9 is connected to a booster water pump, and the booster water pump is electrically connected to the power supply. The booster water pump is prior art, and its specific structure and working principle are prior art, which will not be described in detail here. When the device is in use, the sound wave generator 7 is powered on to work, and water mist is sprayed outward through the ultrasonic atomizing nozzle 5. After the sound wave generator 7 generates sound waves, it first propagates with the air in the cylindrical cavity 6 as the medium. When the sound waves are transmitted outward through the exhaust channel 8, the sound waves are propagated with the water mist as the medium, and the vibration frequency of the water mist is affected by the sound waves. When the sound waves and the water mist are simultaneously propagated into the first lower hopper 4, the sound waves can affect the dust, so that the dust in the air is agglomerated into larger particles by the action of the sound waves and captured and removed by the water mist. At the same time, the dust and the water mist vibrate regularly at the same frequency under the influence of the sound waves, thereby improving the efficiency of the water mist in capturing the powder and improving the dust removal effect of the device.

[0029] A conical cover 10 is fixedly installed at the bottom of the inner wall of the cylindrical cavity 6, and the narrow mouth of the conical cover 10 is fixedly connected to the working end of the sound wave generator 7, and the working end of the sound wave generator 7 is an end that can generate sound waves. A hemispherical sound wave reflection block 11 arranged opposite to the conical cover 10 is fixedly installed on the top surface inside the cylindrical cavity 6, and the hemispherical sound wave reflection block 11 is arranged opposite to the exhaust passage 8. The conical cover 10 can gather the sound waves generated by the sound wave generator 7, guide the sound waves, and increase the energy of the sound waves, thereby improving the transmission effect of the sound waves of the device. The hemispherical sound wave reflection block 11 can reflect the sound waves, so that the sound waves toward the exhaust passage 8 side can be transmitted outward after being rebounded by the hemispherical sound wave reflection block 11, and the sound waves on the side facing away from the exhaust passage 8 can be rebounded by the hemispherical sound wave reflection block 11 and the cylindrical cavity 6 to improve the moving path of the sound waves, so that the sound waves can cover a larger range through the exhaust passage 8.

[0030] An arc-shaped stopper 12 is fixedly installed on the upper part of one end of the exhaust channel 8 extending into the first lower hopper 4, and a vertically arranged guide plate 13 is fixedly installed on the bottom of one end of the exhaust channel 8 extending into the first lower hopper 4. The arc-shaped stopper 12 and the guide plate 13 can both achieve the guiding effect of the sound wave or the water mist, so that the sound wave and the water mist can move in different directions in the first lower hopper 4, increase the coverage area of ​​the sound wave and the water mist, and further improve the dust removal effect of the device.

[0031] A plurality of evenly distributed support rods 14 are fixedly mounted on the top surface of the first lower hopper 4, and a second lower hopper 15 is fixedly mounted on the upper ends of the support rods 14. The lower end of the second lower hopper 15 extends to the top of the first lower hopper 4, and the sonic dust removal assembly is located between the first lower hopper 4 and the second lower hopper 15. The second lower hopper 15 is arranged above the first lower hopper 4, and can protect the exhaust passage 8 and the columnar cavity 6 between the second lower hopper 15 and the first lower hopper 4, prevent the ore from directly contacting the exhaust passage 8, the columnar cavity 6 and other structures during the material discharge process, prevent the sonic dust removal assembly of the device from being damaged, and improve the reliability of the device.

[0032] A dust suction pipe 16 communicating with the interior of the cone crusher body 1 is fixedly installed at the lower part of one side of the cone crusher body 1. The dust suction pipe 16 is connected to a bag dust collector, and the bag dust collector is electrically connected to a power supply. The bag dust collector is a prior art, and its specific structure and working principle are not described in detail here. The bag dust collector cooperates with the dust suction pipe 16 to achieve the suction of dust in the cone crusher body 1. By maintaining a slightly negative pressure state in the cone crusher body 1, dust can be effectively prevented from escaping to the external environment, further improving the dust removal effect of the device.

[0033] Connecting plates 17 are fixedly mounted on the bottom of four sides of the cone crusher body 1 , and mounting holes are formed on the top surfaces of the connecting plates 17 .

[0035] Working principle:

[0036] When the device is in use, a plurality of evenly distributed ultrasonic atomizing nozzles 5 spray water mist in a circular shape into the first lower hopper 4, so that a water curtain is formed on the top of the first lower hopper 4 to prevent dust from escaping. At the same time, the sound wave generator 7 in the sound wave dust removal generates corresponding sound waves, so that dust in the air is agglomerated into larger particles by the sound waves and is more easily captured and removed by the water mist. At the same time, the dust and the water mist vibrate regularly at the same frequency under the influence of the sound waves, thereby further improving the efficiency of the water mist in capturing the powder and improving the dust removal effect of the device.
