Description

Technical Field

[0001] This utility model relates to the field of medium chromium ball production technology, and in particular to a medium chromium ball production device with high wear resistance. Background Technology

[0002] Medium chromium balls are wear-resistant materials widely used in industrial production. Based on their chromium content, they can be divided into high chromium balls, medium chromium balls, and low chromium balls. The chromium content is generally in the range of 5%-10%, which is a critical range that connects the high and low chromium content. This content allows medium chromium balls to have a certain degree of hardness while also having good comprehensive performance.

[0003] In addition to chromium, medium-chromium balls also contain other elements such as carbon, silicon, manganese, and molybdenum. These elements work together to influence the performance of medium-chromium balls, giving them high wear resistance. Currently, there are many production devices for medium-chromium balls, including raw material processing devices, smelting devices, forming devices, sintering devices, etc. Among them, the forming device is further divided into a mixing device for the initial mixing and a ball pressing device for the later forming.

[0004] Currently, in the operation of mixing devices, solid raw materials such as chromium ore, scrap steel, and additives are generally placed inside the mixing device, and these raw materials are mixed by the rotation of the blades to lay the foundation for subsequent smelting, forming and other processes. However, since these solid materials are usually hard, the blades are in direct contact with these materials, and prolonged contact can easily lead to damage to the blades, thereby reducing their service life. Therefore, there is an urgent need for a medium chromium ball production device with high wear resistance to solve the above problems. Utility Model Content

[0033] like Figures 1 to 8As shown in the figure, this embodiment provides a high-wear-resistant medium-chromium ball production device. This high-wear-resistant medium-chromium ball production device includes a lower shell 1, an upper shell 2 installed on the top of the lower shell 1, the lower shell 1 and the upper shell 2 are connected by hinges, and the other side of the two are connected by connecting bolts, which can facilitate the opening of the upper shell 2 and the lower shell 1 to facilitate the replacement of the blades 6 or the rubber sleeves 7. The lower shell 1 and the upper shell 2 together form a mixing shell. The mixing shell is rotatably connected to a first rotating shaft 3 and a second rotating shaft 4. The first rotating shaft 3 is located on one side of the second rotating shaft 4, and the two are on the same horizontal plane. The outer surface of the first rotating shaft 3 and the second rotating shaft 4 both have connecting rings 5. There are multiple sets of connecting rings 5, and the multiple sets of connecting rings 5 ​​are arranged at equal intervals. The outer surface of the connecting rings 5 ​​is equipped with a ring array of blades 6. The blades 6 on the outer surface of the first rotating shaft 3 and the second rotating shaft 4 are staggered to improve the mixing range. The bottom of the lower shell 1 is equipped with a feeding plate connected by hinges (not shown in the figure), and the upper shell 2 is equipped with a feeding hopper.

[0034] The blade 6 is connected to the first shaft 3 and the second shaft 4 via a connecting rod 15. The outer surface of the blade 6 is fitted with a rubber sleeve 7. One end of the rubber sleeve 7 has a connecting sleeve 8. There are two sets of connecting sleeves 8, both of which are conical and correspond to each other. The two sets of connecting sleeves 8 are located on the outer surface of the connecting rod 15. The outer side of the two sets of connecting sleeves 8 is provided with a slot 9. The outer surface of the slot 9 is provided with an elastic band 10, which can easily clamp the connecting sleeve 8 to the connecting rod 15. This helps the rubber sleeve 7 to be firmly installed on the outer surface of the blade 6. The rubber sleeve 7 can buffer the impact force between the blade 6 and the raw material, reduce rigid friction, thereby reducing the wear of the blade 6 and extending the service life of the blade 6.

[0035] The outer surface of the rubber sheath 7 is equipped with guide strips 11. Multiple sets of guide strips 11 are arranged at equal intervals to facilitate the guiding of raw materials, avoid local accumulation or stagnation of materials, and thus improve the uniformity and efficiency of mixing.

[0036] The outer surface of the connecting ring 5 is provided with a connecting groove 501. There are multiple sets of connecting grooves 501 arranged in a circular array. All sets of connecting grooves 501 are arc-shaped. The inner side of the connecting groove 501 has an arc-shaped retaining strip 502. The arc-shaped retaining strips 502 are arranged in pairs and correspond to each other, which facilitates the initial positioning of the connecting rod 15 and the blade 6, making the installation of the blade 6 easier.

[0037] The end of the connecting rod 15 away from the blade 6 has a connecting block 1501 that is adapted to the connecting groove 501. Both sides of the connecting block 1501 are provided with arc-shaped slots 1502 that are adapted to the arc-shaped locking strip 502. The arc-shaped locking strip 502 is located in the arc-shaped slot 1502 and is slidably connected to it, which facilitates the locking operation of the blade 6 and makes it easier to install.

[0038] The connecting rod 15 is connected to the connecting ring 5 by a bolt 12, which is a type of bolt or screw. This facilitates the final fixing of the blade 6, allowing the blade 6 and the connecting ring 5 to be connected more securely.

[0039] A first pulley 301 and a second pulley 401 are provided on one side of the mixing shell. One end of the first rotating shaft 3 and the second rotating shaft 4 extends outside the mixing shell and is fixedly connected to the first pulley 301 and the second pulley 401 respectively.

[0040] The first pulley 301 and the second pulley 401 are connected by a transmission belt 13. A motor 14 is fixedly connected to one side of the mixing shell. The output end of the motor 14 is fixedly connected to the first rotating shaft 3, which can easily drive the first rotating shaft 3 and the second rotating shaft 4 to rotate, so as to facilitate the mixing of materials.

[0041] In use, the material is fed into the mixing shell through the feed hopper, and the motor 14 is started to drive the first rotating shaft 3 to rotate. Under the action of the first pulley 301, the transmission belt 13 and the second pulley 401, the second rotating shaft 4 is driven to rotate, causing multiple sets of blades 6 to rotate and mix the material. During this process, the rubber sleeve 7 will contact the material first. The rubber sleeve 7 can buffer the impact force between the blades 6 and the material, reduce rigid friction, thereby reducing the wear of the blades 6 and extending the service life of the blades 6. When the rubber sleeve 7 needs to be replaced, first remove the elastic band 10, and pull the two sets of conical connecting sleeves 8 to remove the rubber sleeve 7 from the blades 6. When installing, the operation is reversed. In this way, the rubber sleeve 7 can be replaced.

[0042] Meanwhile, when the blade 6 is damaged and needs to be replaced, the connecting ring 5 and the connecting rod 15 are locked by removing the plug 12, and the connecting rod 15 is rotated in the opposite direction so that the connecting block 1501 on one side slides in the connecting groove 501 until it slides to one side of the arc-shaped retaining strip 502, so that the blade 6 can be disassembled. This allows for the quick replacement of the blade 6, which facilitates the maintenance of the blade 6.

[0043] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
