Description

Technical Field

[0001] This utility model relates to the field of wear-resistant steel ball technology, and in particular to a wear-resistant steel ball with a replaceable friction shell. Background Technology

[0002] Ball mills are key equipment for further pulverizing materials after they have been crushed. They are widely used in the production of cement, silicate products, new building materials, refractory materials and other industries for dry or wet grinding of various ores and other grindable materials. When grinding ores in a ball mill, wear-resistant steel balls are indispensable. By colliding with the ores, the ores are ground into particles of the required size.

[0003] Existing wear-resistant steel balls generally adopt an integrated design, meaning the entire steel ball is an indivisible whole structure. When the ball mill is running, the steel balls move continuously with the rotation of the cylinder, colliding and rubbing against each other and with the material. Once local damage occurs due to collisions or other reasons during operation, the entire steel ball must be replaced. Because it is impossible to repair the damaged parts specifically, some steel balls with most of their parts still intact are prematurely scrapped, failing to fully realize their remaining value, resulting in waste of resources and increased costs.

[0004] Therefore, there is an urgent need to provide a wear-resistant steel ball with a replaceable friction shell to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a wear-resistant steel ball with a replaceable friction shell.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: providing a wear-resistant steel ball with a replaceable friction shell, including a steel ball body, wherein a first wear-resistant shell is nested at the top of the steel ball body, and a second wear-resistant shell is nested at the bottom of the steel ball body; The steel ball body has a connecting slot inside, the bottom of the first wear-resistant shell has a first splicing slot, and the top of the second wear-resistant shell has a second splicing slot. The connecting slot is equipped with an assembly mechanism that connects the steel ball and the wear-resistant shell into a whole. The assembly mechanism is equipped with a fixing mechanism that ensures a firm connection between the components.

[0007] Through the above technical solution, the steel ball body is protected against wear by the first wear-resistant outer shell and the second wear-resistant outer shell, thereby improving the service life of the wear-resistant steel ball.

[0008] The present invention is further configured such that: the assembly mechanism includes an assembly tube fitted and installed inside the connecting slot, the first splicing slot and the second splicing slot, the inner wall of the assembly tube is fixed with a positive and negative mounting block, and a limit block is fixed on one side of the positive and negative mounting block.

[0009] Using the above technical solution, the assembly tube is used to splice and assemble the steel ball body, the first wear-resistant outer shell, and the second wear-resistant outer shell.

[0010] The present invention is further configured such that: both sides of the assembly insert are provided with installation chambers, and installation plates are fitted inside the two installation chambers.

[0011] The above technical solution allows the mounting plate to be disassembled and reassembled, thereby enabling the maintenance and replacement of parts inside the mounting compartment.

[0012] The present invention is further configured such that: a plurality of evenly distributed spring rods are fitted inside the installation compartment, and a cylindrical spring is nested outside the spring rods, with one end of the cylindrical spring being fixedly connected to one side of the installation plate.

[0013] Using the above technical solution, the cylindrical spring drives the spring rod to retract into the installation chamber.

[0014] The present invention is further configured such that: the fixing mechanism includes a housing insert block fitted and installed at one end of the assembly insert, a connecting rod is fixed at one end of the housing insert block, and a rod push block is fixed to the outside of the connecting rod.

[0015] With the above technical solution, the docking rod and the insertion rod push block are inserted into the assembly cylinder through the gap between the positive and negative mounting blocks. By reciprocating the rotation of the docking rod, the docking rod can be fully inserted into the assembly cylinder. The limiting block can limit the rotation angle of the docking rod through the insertion rod push block. After the insertion rod push block and the limiting block are in contact, the insertion rod push block will push out the spring insertion rod, so that the spring insertion rod is inserted into the steel ball body.

[0016] The present invention is further configured such that: a housing insert plate is fitted and installed at the other end of the assembled insert, and a push block insert rod is fixed at one end of the housing insert plate; the outside of the push block insert rod is connected to the inside of the positive and negative mounting blocks and the insert rod push block.

[0017] Through the above technical solution, the outer shell insert plate connects the positive and negative mounting blocks and the insert rod push block through the push block rod, preventing the insert rod push block from becoming loose.

[0018] The present invention is further configured such that a fixing screw with one end penetrating through and extending into the interior of the connecting rod is threaded onto one side of the outer shell insert plate.

[0019] The above technical solution uses screws to thread-fix the outer shell insert plate and the connecting rod, thereby limiting the outer shell insert plate and the outer shell block on both sides of the first wear-resistant outer shell and the second wear-resistant outer shell.

[0020] The beneficial effects of this utility model are as follows: 1. This utility model has an assembly mechanism that allows the assembly insert to connect the steel ball body and the wear-resistant outer shell into a whole. The detachable design enables the individual replacement of damaged parts, avoiding the situation where the whole is scrapped due to partial damage. This greatly improves the utilization rate of materials, reduces resource waste, and also facilitates personalized configuration and maintenance, reducing the number of new steel balls purchased and maintenance costs. 2. This utility model, by providing a fixing mechanism, can fix the assembly mechanism, prevent the internal structure from loosening, ensure the firm connection between the components, guarantee the stability and safety of the steel ball during high-speed operation, and allow for flexible selection and replacement of components according to actual wear conditions, thus extending the overall service life of the steel ball.

[0024] Please see Figures 1-4A wear-resistant steel ball with replaceable friction shells includes a steel ball body 1, a first wear-resistant shell 2 nested at the top of the steel ball body 1, and a second wear-resistant shell 3 nested at the bottom of the steel ball body 1; the steel ball body 1 has a connecting slot 4 inside, the bottom of the first wear-resistant shell 2 has a first splicing slot 5, and the top of the second wear-resistant shell 3 has a second splicing slot 6; the connecting slot 4 has an assembly mechanism 7 inside that can connect the steel ball and the wear-resistant shell into a whole, the assembly mechanism 7 includes an assembly insert 701 fitted into the connecting slot 4, the first splicing slot 5, and the second splicing slot 6, the inner wall of the assembly insert 701 is fixed with a positive and negative mounting block 702, and one side of the positive and negative mounting block 702 is fixed with a limit block 703; the assembly insert 701... The steel ball body 1 is provided with mounting chambers 704 on both sides. Mounting plates 705 are fitted inside the two mounting chambers 704. Multiple evenly distributed spring rods 706 are fitted inside the mounting chambers 704. A columnar spring 707 is nested outside the spring rods 706. One end of the columnar spring 707 is fixedly connected to one side of the mounting plate 705. The steel ball body 1 is protected against wear by the first wear-resistant shell 2 and the second wear-resistant shell 3 to improve the service life of the wear-resistant steel ball. The assembly tube 701 splices and assembles the steel ball body 1, the first wear-resistant shell 2 and the second wear-resistant shell 3. The mounting plate 705 can be disassembled and installed to maintain and replace the internal parts of the mounting chamber 704. The columnar spring 707 drives the spring rods 706 to retract into the mounting chamber 704.

[0025] like Figure 3As shown, the assembly mechanism 7 has a fixing mechanism 8 inside to ensure a firm connection between the components. The fixing mechanism 8 includes a housing insert block 801 fitted into one end of the assembly insert 701. A connecting rod 802 is fixed to one end of the housing insert block 801, and a rod pusher block 803 is fixed to the outside of the connecting rod 802. A housing insert plate 804 is fitted into the other end of the assembly insert 701. A pusher rod 805 is fixed to one end of the housing insert plate 804.

By reciprocating rotation of the connecting rod 802, it can be fully inserted into the assembly sleeve 701. The limiting block 703, through the insert rod push block 803, can connect the connecting rod 802... The rotation angle of 02 is limited. After the insertion rod push block 803 and the limiting block 703 are in contact, the insertion rod push block 803 will push out the spring insertion rod 706, so that the spring insertion rod 706 is inserted into the steel ball body 1. The outer shell plate 804 connects the positive and negative mounting blocks 702 and the insertion rod push block 803 through the push block insertion rod 805 to prevent the insertion rod push block 803 from loosening. The outer shell plate 804 and the connecting rod 802 are threadedly fixed by the fixing screw 806, so that the outer shell plate 804 and the outer shell block 801 limit the two sides of the first wear-resistant outer shell 2 and the second wear-resistant outer shell 3, thereby completing the replacement operation of the wear-resistant steel ball outer shell.
