Abstract
Description
Technical Field
[0001] The utility model relates to a buffer system, in particular to a pellet mixture buffer system, and belongs to the technical field of pellet storage. Background Art
[0002] Steel is an important food for industry, an important guarantee for construction, and an important support for the economy. As the most important raw material industry, the steel industry provides steel products that meet the needs of social development, national security, and people's lives. There are basically two processes for the manufacture of steel. One of the important processes is the production of pig iron. Blast furnace ironmaking is the main ironmaking process used in China.
[0003] The iron-containing materials loaded into the blast furnace are mainly natural rich iron ore (lump ore), sintered ore and pelletized ore. Natural rich iron ore is becoming increasingly scarce, requiring the production of large quantities of high-grade concentrate. In order to improve the technical and economic indicators of ore dressing, it is necessary to finely grind the iron ore. Too fine concentrate powder is difficult to sinter, and roasting pelletized ore is an effective way to process finely ground concentrate.
[0004] The existing main pelletizing process is to mix iron ore concentrate, bentonite and dust, then make pellets on a pelletizing machine, and then dry, preheat, roast, high-temperature consolidate and cool the made pellets to obtain finished pellets. The pelletizing process is extremely important in the existing pelletizing process. If the pelletizing effect is not good, it will inevitably affect the subsequent roasting and the yield will be greatly reduced. There are many factors that affect pelletizing. In the prior art, the mixed mixture is directly used for pelletizing. The time from mixing to pelletizing is too short, so that the bentonite has not yet played a good bonding role before the pelletizing begins, and the quality of the balls made in this way is not high.
[0005] The pellet mixture contains raw materials such as iron ore concentrate, bentonite, and dust. Due to various uncertain factors in actual production, the raw material supply is unstable. However, pellet production requires continuity, so the pellet mixture needs to be mixed and cached to maintain production continuity.
[0006] In addition, when a rotary discharging device is used for discharging, the pressure on the rotating disk of the rotary discharging device is relatively large, which may cause the rotation speed of the rotating disk to slow down or shorten the service life of the rotary discharging device, thereby affecting the efficiency of the entire process.
[0007] Therefore, in order to improve the quality of pellets, extend the time from mixing to pelletizing, cache the pellet mixture after mixing, and maintain production continuity, it is necessary to develop and design a pellet mixture storage device and method to solve the problems arising in the above-mentioned prior art.

[0029] Preferably, the vibration bucket is in the shape of an inverted truncated cone.
[0030] In the utility model, a discharging barrel and a rotating discharging device are arranged below the storage bin. During the preparation of pellets, the pellet mixture is loaded into the storage bin. The mixture can be stored in the storage bin for a long time, which is also conducive to the various raw materials being more closely connected to each other under the action of bentonite, increasing the spheroidization of the mixture, improving the subsequent spheroidization rate, and greatly improving the quality of the pellets. At the same time, a vertical support plate and an inclined guide plate are arranged inside the discharging barrel, which can not only reduce the pressure of the material column on the rotating discharging device, improve the discharging efficiency, and extend the service life of the rotating discharging device, but also there is an opening between the vertical support plate and the side wall of the cylinder, and the material flows from the opening to the discharging port and is quickly discharged under the action of the rotating discharging device. In addition, during the process of discharging the pellets from the storage bin, the pellets are driven to be discharged from the discharging barrel by the rotating discharging device, so as to realize continuous discharging and maintain the continuity of production. The pellets made of the mixture cached by this system have better compressive strength, pellet size and anti-fall ability.

In addition, the inclined angle formed by the inclined guide plate and the bottom surface of the discharge barrel is also limited to 40°~60°.

The angle α formed by the line connecting the end points on both sides of the bottom of the discharge port and the bottom center of the discharge barrel is 60°~180°, which is conducive to the continuous and stable discharge of materials.
[0033] In the utility model, a central baffle plate and an outer baffle plate are provided in the discharge barrel. The central baffle plate passes through one end of the discharge port from the center of the discharge barrel, and a discharge channel can be formed inside and outside the discharge barrel. The material in the discharge barrel can be quantitatively discharged from the discharge port through the baffle plate and continuously discharged in the same direction, and then the material in the storage bin flows from the top of the bin to the bottom of the bin, realizing continuous production. The part of the central baffle plate located outside the discharge barrel and the outer baffle plate prevent the movement direction of the pellets after discharge from being inconsistent, and guide the material to the selected direction.
[0034] In the utility model, a vibrating bucket is hung at the bottom of the storage bin, which can further increase the storage volume of the material, and a vibrator is arranged on the vibrating bucket to enhance the fluidity of the material, prevent the material from sticking to the bin wall and forming scabs due to long-term storage in the storage bin, and avoid material blockage to ensure the smooth flow of the material. Preferably, the vibrating bucket is connected to the storage bin through a connecting rod, which can better play the role of the vibrating bucket and enhance the vibration effect. A buffer pad is arranged at the connection between the connecting rod and the ear seat, which can effectively protect the ear seat connection and reduce the damage of the vibration to the vibrating bucket and the storage bin body. In addition, the upper part of the vibrating bucket is sleeved on the outer side of the bottom of the storage bin, which ensures that the material will not overflow during vibration and provides amplitude space for vibration.
[0035] In the utility model, the first supporting device is adopted to set the storage bin on the upper platform, which can raise the height of the storage bin, further increase the storage capacity, and improve the utilization rate of the unit area of land. Preferably, the first supporting device is a supporting weighing device, which weighs the weight of the material in the bin in real time, stops feeding when the material is full, and starts feeding when the material is low, which not only has a high degree of automation, saves manpower and material resources, but also prolongs the storage time of the mixed material in the storage bin.
[0036] In the utility model, the storage bin is cylindrical in the upper part and inverted truncated cone in the lower part, and the angle between the truncated cone side wall and the horizontal plane is greater than 65°, which can not only increase the storage capacity of the storage bin, but also improve the fluidity of the material during discharge to prevent blockage.
[0037] In the utility model, in the rotary discharging device, the output power of the rotary drive motor can be adjusted by the motor power controller, thereby adjusting the rotation speed of the rotary disk, which can be suitable for different material amounts.
[0038] In the utility model, the support legs of the second support device are height-adjustable, and the angle of the bottom plate is also adjustable, so that the system can adapt to various types of lower platforms, improve the scope of application and site utilization, and save investment costs.
[0039] Compared with the prior art, the utility model has the following beneficial effects:
[0040] 1. The utility model provides a pellet mixture buffer system, which can store the mixture for a long time through the combination of a storage bin and a discharge barrel, which is beneficial for various raw materials to be more closely connected to each other under the action of bentonite, and increases the ball-forming property of the mixture. At the same time, vertical support plates and inclined guide plates are arranged inside the discharge barrel, which can not only reduce the pressure of the material column on the rotary discharge device, improve the discharge efficiency, and extend the service life of the rotary discharge device, but also guide the material to the vicinity of the discharge port, so that the material is quickly discharged under the action of the rotary discharge device.
