Description

Technical Field

[0001] The utility model relates to the field of separation and purification of chromite ore, in particular to a vibration boiling separator for purifying chromite ore. Background Art

[0002] Chromite sand is a special sand for casting. It is a natural spinel mainly composed of chromite. After crushing and screening into a specified particle size, it is suitable for molding (core making) sand. Chromite sand has excellent chilling characteristics in casting, small linear expansion, does not react with other metal oxides, and has good resistance to metal penetration. When used for large carbon steel and manganese steel castings, it can effectively prevent casting defects such as mechanical sand sticking and cracks, and can also promote sequential solidification to ensure the quality of castings. A large amount of waste chromite sand is generated in the casting production process, which cannot be directly reused and must be processed before it can be recycled.

[0003] In the existing old sand regeneration process, screening is often carried out through a vibrating screening machine. The vibrating screening machine generally includes a vibrating body and a vibrating motor installed on the vibrating body. The vibrating motor is fixed to both sides of the vibrating body by bolts. When the vibrating screening machine is working, the chromite ore with a higher density is located in the lower layer during the vibration of the vibrating body and moves forward with the vibration of the vibrating body; the quartz sand and impurities with a relatively lower density are located in the upper layer during the vibration of the vibrating body and move backward with the vibration of the vibrating body, thereby achieving the purification of the chromite ore. However, in actual use, it was found that there are still many impurities in the chromite ore after screening, and simple vibration screening cannot separate the impurities from the chromite ore well.

[0004] Therefore, this field needs a new technical solution to solve the above problems. Summary of the invention

[0005] In order to improve or solve the technical problem that the screening machine in the prior art cannot separate impurities and chromite sand well, the utility model provides a vibration boiling separator for purifying chromite sand. The vibration boiling separator for purifying chromite sand includes: a machine base, including a base and a discharge hopper and a slag hopper installed on the base; a vibration conveying device installed on the base, the vibration conveying device includes a conveying trough body, a vibration motor driving the conveying trough body to vibrate, and a honeycomb plate installed in the conveying trough body; the two ends of the conveying trough body are respectively connected to the discharge hopper and the slag hopper; an airflow boiling device, including a blower, an air duct connected to the blower, and a plurality of branch pipes installed on the air duct, and the end of the branch pipe away from the air duct is arranged below the honeycomb plate; each branch pipe is provided with a pressure regulating valve.

[0006] The utility model discloses a vibrating boiling separator for purifying chromite ore, which includes a machine base, a vibrating conveying device and an airflow boiling device. The machine base includes a base and a discharging hopper and a slag hopper installed on the base. The base is used to install various components. The discharging hopper is used to store the purified chromite ore, and the slag hopper is used to store the separated impurities. The vibrating conveying device includes a conveying trough, a vibrating motor and a honeycomb plate. The honeycomb plate is installed in the conveying trough, and the vibrating motor is installed on both sides of the conveying trough. The vibrating motor drives the conveying trough to vibrate, and then drives the chromite ore above the honeycomb plate to vibrate, thereby separating the chromite ore and impurities. The airflow boiling device includes a blower, an air duct and a branch pipe, one end of which is arranged below the honeycomb plate, and can blow air to the chromite ore through the through holes on the honeycomb plate, so that the impurities in the chromite ore are blown above the chromite ore, further improving the purification effect of the chromite ore. At the same time, the closer to the discharging hopper, the thicker the thickness of the chromite ore, and the greater the wind force required. The pressure regulating valve can adjust the wind pressure in the branch pipe, so as to better separate the chromite sand and impurities. Through the above-mentioned setting, the vibration boiling separator for purifying chromite sand of the utility model can better separate the impurities in the chromite sand by setting the airflow boiling device, thereby improving the purification effect of the chromite sand.

[0007] In the preferred technical solution of the vibrating boiling separator for purifying chromite sand, a shock-absorbing rubber spring is arranged between the conveying trough and the base. Through the above arrangement, the shock-absorbing rubber spring can absorb the vibration and impact energy generated by the conveying trough during operation, reducing the vibration and noise of the equipment.

[0008] In the preferred technical solution of the above-mentioned vibration boiling separator for purifying chromite ore, a compensator is arranged between the blower and the air duct.

[0010] In the preferred technical solution of the vibrating boiling separator for purifying chromite sand, an intermittent discharging device is arranged at the discharging port, and the intermittent discharging device includes a sand discharging detector for obtaining the state of the discharging port, and a sealing plate for selectively closing the discharging port; the sealing plate is configured to open the discharging port when the discharging port is full. Through the above arrangement, the sand discharging detector is used to detect whether the discharging port is full; when the discharging port is full, the sealing plate moves away from the discharging port, so that the discharging port is opened and the material is discharged from the discharging port.

[0011] In the preferred technical solution of the vibration boiling separator for purifying chromite ore, the intermittent discharging device further includes a fixed plate fixedly connected to the conveying trough body, a sliding plate fixedly connected to the sealing plate, a guide rod connecting the fixed plate and the sliding plate, and an air bag arranged between the fixed plate and the sliding plate; the air bag is configured to push the sliding plate to move toward the discharge port when expanded. Through the above arrangement, the sealing plate is driven to move by the expansion and contraction of the air bag, thereby controlling the opening and closing of the discharge port, which has a simple structure and is easy to use.

[0012] In the preferred technical solution of the vibrating boiling separator for purifying chromite sand, the guide rod has an extension extending from the sliding plate; a return spring abutting against the sliding plate is sleeved on the circumferential outer side of the extension. Through the above arrangement, the arrangement of the return spring can drive the sliding plate to move toward the fixed plate after the airbag contracts, that is, drive the sealing plate away from the discharge port.

When the discharging port 211 is full, the sealing plate 52 opens the discharging port 211 so that the chromite sand can fall into the discharging hopper 12; when the discharging port 211 is not full, the sealing plate 52 closes the discharging port 211, and the chromite sand cannot fall into the discharging hopper 12. Further, the intermittent discharging device also includes a fixed plate 53 fixedly connected to the conveying trough body 21, a sliding plate 54 fixedly connected to the sealing plate 52, a guide rod 55 connecting the fixed plate 53 and the sliding plate 54, and an air bag 56 arranged between the fixed plate 53 and the sliding plate 54. Specifically, the airbag 56 is connected to the air circuit system 58. When the air circuit system 58 inflates the airbag 56 and the airbag 56 begins to expand, it will push the sliding plate 54 to move, and then push the sealing plate 52 to move toward the discharge port 211, thereby closing the discharge port 211, and the airbag 56 will always provide thrust for the sealing plate 52 when it expands to prevent the chromite sand from pushing the sealing plate 52 away; when the air circuit system 58 inhales, the airbag 56 opens and contracts, and the sealing plate 52 can be pushed away from the discharge port 211 by the chromite sand, thereby opening the discharge. Further, the guide rod 55 has an extension portion 551 extending out of the sliding plate 54, and a return spring 57 that abuts against the sliding plate 54 is sleeved on the circumferential outer side of the extension portion 551. Specifically, when the sliding plate 54 moves toward the discharge port 211 , the return spring 57 contracts. When the airbag 56 contracts, the return spring 57 returns to its original position, thereby pushing the sliding plate 54 to move toward the fixed plate 53 , thereby facilitating the sealing plate 52 to open the discharge port 211 .
