Description

Technical Field

[0001] This utility model relates to the field of powder funnel technology, and in particular to a three-lobe rotor powder funnel. Background Technology

[0002] Due to the poor ore occurrence and intermittent distribution (commonly known as "chicken coop mine") in our mine, ore dilution is easily caused during mining, making quality control difficult. A certain proportion of impurities are mixed in the finished product after crushing, affecting its quality. These impurities have a significant color difference from qualified ore. Therefore, the mine is researching the use of color sorting for secondary processing and quality improvement of the finished product. During the installation of the color sorters, because the color sorters require stable and uniform feeding, and to save costs, two color sorters need to be installed simultaneously, fed by a single conveyor belt. Therefore, powder funnels need to be installed at the input ends of the two color sorters. The ore on the conveyor belt is then transported to the two color sorters through the powder funnels for secondary processing and quality improvement. However, the existing powder funnels lack a material distribution mechanism; the material is only distributed through two outlets after entering the powder funnel, which cannot solve the problem of uniform and stable material distribution. Therefore, this solution proposes a three-lobe rotor powder funnel to address the above problems. Utility Model Content

[0003] The purpose of this invention is to provide a three-lobe rotor powder funnel to solve the problems mentioned in the background art.

One end of the three-lobe rotor body is rotatably connected to the inner wall of the housing away from the cover plate, and the end of the three-lobe rotor body away from the housing is connected to the inner wall of the cover plate near the housing. The outer walls of both ends of the three-lobe rotor body are rotatably sleeved with the support portion, and the outer wall of the end of the three-lobe rotor body near the cover plate is sleeved with the adjustment portion.

[0007] Preferably, the support portion includes support bearings, the inner walls of the plurality of support bearings are respectively rotatably sleeved with the outer walls at both ends of the three-lobe rotor body, and the ends of the plurality of support bearings that are close to each other are respectively fixedly connected to the ends of the housing and the cover plate that are far from each other.

[0011] The technical effects and advantages of this utility model are as follows: This invention features a material distribution mechanism within the housing. Material is fed into the housing through the inlet, and the material's own weight drives the three-lobe rotor to rotate. The rotation of the three-lobe rotor drives the eccentric shaft to rotate, which in turn drives the tension bearing seat to rotate. The tension bearing seat then pulls the spring to expand. As the weight of the material increases, the force on the three-lobe rotor increases, causing the rotor to lose its balance. This causes the material to slide down the three-lobe rotor to the first or second outlet, thus uniformly and stably distributing the material within the housing through the three-lobe rotor.

The feed port 2 is set at the top of the housing 1, the first discharge port 3 and the second discharge port 4 are set at the bottom of the housing 1, the arc plate 16 is welded to the inner wall of the housing 1, and multiple stop baffles 15 are respectively set at the top and bottom of the housing 1. The stop baffles 15 restrict the rotation position of the three-lobe rotor body 5 to prevent the three-lobe rotor body 5 from rotating too much within the housing 1. The arc plates 16 are symmetrically fixedly installed on the inner walls at both ends of the housing 1. The arc plates 16 are used to prevent premature material discharge that causes the three-lobe rotor body 5 to reset prematurely. The material distribution mechanism is located inside the housing 1. The material distribution mechanism includes a material distribution part and a support part. The two ends of the material distribution part are respectively inserted and connected to the ends of the housing 1 and the cover plate 14 that are close to each other.

It should be noted that the ends of the multiple support bearings 12 that are close to each other are fixedly connected to the ends of the housing 1 and the cover plate 14 that are far from each other. The inner walls of the multiple support bearings 12 are rotatably sleeved with the outer walls of both ends of the three-lobe rotor body 5. The support bearings 12 support the three-lobe rotor body 5 and assist the three-lobe rotor body 5 to rotate. The three-lobe rotor body 5 is set inside the housing 1. One end of the three-lobe rotor body 5 passes through the housing 1 and is sleeved with the inner wall of one of the support bearings 12. The other end of the three-lobe rotor body 5 passes through the cover plate 14 and is sleeved with another support bearing 12. The end of the three-lobe rotor body 5 that passes through the cover plate 14 is sleeved with the adjustment mechanism. The material is conveyed into the housing 1 through the feed port 2. The material in the housing 1 is distributed by the cooperation of the adjustment mechanism and the three-lobe rotor body 5 so that the material is evenly discharged through the first discharge port 3 and the second discharge port 4. An adjustment mechanism is provided at the end of the cover plate 14 away from the housing 1. The adjustment mechanism includes an adjustment part and a mounting part. The mounting part is fixedly connected to the end of the cover plate 14 away from the housing 1, and the adjustment part is inserted into the end of the mounting part away from the cover plate 14. The adjustment part is used to adjust the rotation of the material distribution part.

[0026] Specifically, the regulating section includes: Eccentric shaft 9, the inner wall of eccentric shaft 9 is sleeved with the outer wall of one end of the three-lobe rotor body 5 near the cover plate 14; Tension bearing housing 6 is fixedly installed on the end of eccentric shaft 9 away from cover plate 14; Spring 7 is located at the bottom of tension bearing seat 6, and one end of spring 7 is fixedly connected to the bottom of tension bearing seat 6; The tension adjusting screw 8 is fixedly connected to the end of the spring 7 away from the tension bearing seat 6 at its top, and the end of the tension adjusting screw 8 away from the spring 7 is inserted into the mounting part. Specifically, the mounting part includes a mounting bracket 13, which is fixedly mounted on the end of the cover plate 14 away from the housing 1. The end of the mounting bracket 13 away from the cover plate 14 is inserted and connected to the end of the tension adjusting screw 8 away from the spring 7. Furthermore, tension adjusting nuts 10 are rotatably connected to the top and bottom of the mounting bracket 13, and the inner walls of the multiple tension adjusting nuts 10 are threadedly connected to the outer wall of the tension adjusting screw 8. It should be noted that one end of the mounting bracket 13 is fixedly connected to the end of the cover plate 14 away from the housing 1, and the end of the mounting bracket 13 away from the cover plate 14 is slidably connected to the tension adjusting screw 8. The top and bottom of the mounting bracket 13 are respectively rotatably connected to multiple tension adjusting nuts 10. The inner walls of the multiple tension adjusting nuts 10 are threadedly sleeved with the outer wall of the tension adjusting screw 8. The inner wall of the eccentric shaft 9 is sleeved with the outer wall of the end of the three-lobe rotor body 5 near the cover plate 14. The end of the eccentric shaft 9 away from the three-lobe rotor body 5 is fixedly connected to the tension bearing seat 6. The spring 7 is set between the tension bearing seat 6 and the tension adjusting screw 8. One end of the spring 7 is fixedly connected to the bottom of the tension bearing seat 6, and the other end of the spring 7 is fixedly connected to the end of the tension adjusting screw 8 away from the mounting bracket 13. When the equipment is in a stopped state or no material is coming in, the tension bearing seat 6 is rotated by the elastic force of the spring 7. The rotation of the tension bearing seat 6 drives the eccentric shaft 9 to rotate, which in turn drives the three-lobe rotor body 5 to rotate, placing the three-lobe rotor body 5 in either the first discharge port 3 or the second discharge port 4 working state. When the machine is started and material enters from the feed port 2, assuming the three-lobe rotor body 5 is in the first discharge port 3 working state, the gravity generated by the material causes the three-lobe rotor body 5 to rotate clockwise. The force exerted by the material on the three-lobe rotor body 5 and the tension of the spring 7, through the eccentric shaft 9, form a pair of balanced forces. As the weight of the material increases, the clockwise force on the three-lobe rotor body 5 increases, causing the three-lobe rotor body 5 to lose balance. The three-lobe rotor body 5 rotates clockwise to the stop baffle 15 at the top of the second discharge port 4, and at the same time, the material is discharged from the second discharge port 4, and the device switches to the second discharge port 4 working state. Similarly, when the material enters the second discharge port 4, the three-lobe rotor body 5 rotates counterclockwise to the stop baffle 15 at the top of the first discharge port 3, and the material is discharged from the first discharge port 3. The device then switches to the working state of the first discharge port 3, and this cycle repeats. Since the balancing force when the three-lobe rotor body 5 rotates unbalancedly in both directions is generated by the tension of the spring 7 through the eccentric shaft 9, and their torques are equal, the weight of the material discharged from the first discharge port 3 and the second discharge port 4 each time is equal, achieving the purpose of uniform material distribution between the two color sorters. Simultaneously, this weight is used as the unit of measurement. By calculating the pulse signal generated by the position of the tension bearing seat 6 sensed by the sensor 11, the negative feedback adjustment and measurement of the conveyor belt are achieved. The tension adjustment screw 8 and the two tension adjustment nuts 10 can be adjusted to adjust the tension of the spring 7, thereby adjusting the size of the unit of measurement. Through the torque balance system composed of the three-lobe rotor body 5, the spring 7 and the eccentric shaft 9, the automatic sensing and dynamic distribution of material weight are realized, and the pulse signal sensed by the sensor 11 is converted into a conveyor belt speed adjustment command to form a closed-loop control.
