Description

Technical Field

[0001] The utility model relates to the technical field of pellet processing, in particular to a pellet grinding structure. Background Art

[0002] Pelletized ore is a method of artificial block raw materials. It is a process of transforming a powdered material into a material with physical properties and chemical composition that can meet the requirements of the next step of processing. Pelletized ore is a spherical artificial iron ore with a diameter of about 10-16mm and a compressive strength of more than 200N. Pelletized ore can be transported over long distances and stored for a long time. It is an ideal raw material for blast furnace ironmaking. It can also be used for the production of sponge iron. The following problems exist in the prior art: Under the prior art, when producing pelletized ore, it is necessary to mix the ore and the combustion agent to granulate in order to ensure that the ore and the fuel are evenly mixed. However, the current process cannot quickly separate the particles that reach the required particle size during granulation. It can only be separated uniformly after granulation, which easily leads to different particle sizes of granulated ore, and it is not convenient to accurately control the amount of pelletized ore when adding it. Utility Model Content

[0003] The utility model provides a pelletizing ore grinding structure, which solves the above-mentioned technical problems.

[0004] The utility model solves the above-mentioned technical problems as follows:

[0005] A pelletizing ore grinding structure comprises a base, a gear ring, a material frame and a screen frame, wherein a accommodating cavity is provided in the base, a cylinder is installed in the accommodating cavity of the base, a telescopic rod is provided in the cylinder, the top of the telescopic rod is connected to the screen frame, a ball is installed on the base, a material frame is provided on the base via a ball support frame, the screen frame is located inside the material frame, a gear ring is provided on the outside of the material frame, a motor is installed on one side of the base, a gear is installed on the output end of the motor, and the motor is connected to the material frame through the gear and the gear ring.

[0006] On the basis of the above technical solution, the present invention can also be improved as follows.

[0007] Furthermore, the balls are evenly distributed on the base, the material frame is supported by the balls, and the material frame is rotatably mounted on the base by the balls.

[0008] The beneficial effects of adopting the above further scheme are:

[0009] By evenly distributing the balls on the base, the material frame can rotate smoothly, thus reducing the shaking and instability of the material frame during the rotation process. This design improves the stability and accuracy of the material frame rotation. The uniform distribution of the balls can ensure that the force on the material frame during the rotation process is also evenly distributed, avoiding the distortion or deformation of the material frame when subjected to uneven forces. This helps the material frame maintain its shape and stability. The balls have a certain elasticity and can play a role in buffering and shock absorption. When the material frame is subjected to external impact, the balls can absorb part of the impact energy, reduce the vibration and deformation of the material frame, and improve the stability and reliability of the equipment.

[0010] Furthermore, a bearing is provided on the screen frame, and the telescopic rod is connected to the screen frame through the bearing, so that the screen frame can be raised and lowered in the material frame while rotating.

[0011] The beneficial effects of adopting the above further scheme are:

[0012] The screen frame can be raised and lowered while rotating, which can increase the tumbling and vibration of the material in the screen frame, helping to improve the screening effect. This design helps to overcome the retention and blockage of materials and improve the efficiency and effect of screening. The rotation and lifting of the screen frame can be carried out continuously, allowing the material to pass through the screen faster and improve production efficiency. This design helps to achieve continuous screening and transportation of materials and improve overall production efficiency.

[0013] Furthermore, a limiting block is provided on the outer side of the screen frame, a groove is provided on the inner surface of the material frame, and the screen frame is installed in the material frame by limiting the material frame and the groove.

[0014] The beneficial effects of adopting the above further scheme are:

[0015] The design of the limit block and the groove can limit the movement of the screen frame in the material frame, which helps the screen frame to remain stable and improve the screening effect. This design can prevent the screen frame from tilting in the material frame and ensure the stability of the screening process. The design of the limit block and the groove can make the installation and removal of the screen frame more convenient. This design simplifies the installation process and improves the maintainability and repairability of the equipment. Since the screen frame is installed in the material frame through the material frame and the groove limit, when the screen needs to be replaced, the screen frame can be easily removed without disassembling the entire equipment. This design improves the maintainability and maintainability of the equipment.

[0016] Furthermore, the limit blocks are evenly distributed on the screen frame, and the limit blocks correspond to the positions of the grooves on the inner side of the material frame, thereby facilitating the screen frame to be guided by the grooves of the material frame and lifted and installed in the material frame.

[0017] The beneficial effects of adopting the above further scheme are:

[0018] The design of the stopper and the groove can guide the screen frame to rise and fall in the material frame, and prevent the screen frame from deflecting or tilting during the lifting process. This design can improve the guidance and stability of the screen frame lifting and lowering, and ensure the smooth operation process. By making the stopper correspond to the position of the groove on the inner side of the material frame, the installation and removal of the screen frame can be simplified. This design simplifies the installation process and improves the maintainability and repairability of the equipment.

[0019] Furthermore, a reduction box is installed at the output end of the motor, the gear is located at the output end of the reduction box, and the motor is connected to the gear ring of the material frame through the reduction box and the gear, and then drives the material frame to rotate through the reduction box.

[0020] The beneficial effects of adopting the above further scheme are:

[0021] The reduction box can reduce the high speed of the motor to a low speed suitable for the rotation of the material frame, while increasing the output torque to meet the load requirements during the rotation of the material frame. The design of the gears and shafts inside the reduction box can optimize the transmission efficiency, reduce the energy loss of the transmission, and improve the transmission efficiency of the whole machine. The gears connected to the output end of the reduction box can be easily disassembled and replaced without disassembling the reduction box, which is convenient for maintenance and repair. The compact structure of the reduction box and gears can reduce the volume and space occupied by the whole machine, making the equipment more compact, lightweight and easy to move.

[0022] The beneficial effects of the utility model are:

[0023] 1. The structure uses components such as base, gear ring, material frame and screen frame. The components are closely matched, the overall structure is compact and occupies a small area. This makes the equipment not take up too much space when working, and is convenient for installation and use in limited places such as mines.

[0024] 2. The screen frame is located inside the material frame and is connected to the bearing through a telescopic rod. It can move up and down inside the material frame while rotating. This design allows the material to be fully stirred and screened during the screening process, improves the screening effect, avoids material accumulation and blockage, and ensures the quality and uniformity of the mineral.

[0025] 3. Ball bearings are installed on the base to support the material frame, which is installed on the base through the rotation of the balls. This support method has the characteristics of good stability, low friction, and smooth rotation. It can ensure that the material frame will not deviate or get stuck during rotation, thus increasing the service life of the equipment.

[0026] 4. A motor and a reduction gearbox are installed on one side of the base, and the motor is connected to the material frame through gears and gear rings. This transmission method has the characteristics of high transmission efficiency and large transmission torque, which can drive the material frame to rotate quickly and withstand large loads. At the same time, the use of the reduction gearbox can convert the high speed and low torque output by the motor into the low speed and high torque required by the material frame, thereby improving the transmission efficiency and energy utilization.
