The basic form of the vertical mixing kettle is cylindrical. The power device drives the mixing main shaft to rotate, driving the mixing legs to rotate in a circle in the mixing kettle to achieve the mixing of the materials. The mixing legs are arranged radially according to a certain rule, generally with two legs, three legs, or four legs. The more stable the position of the legs relative to the center of the mixing kettle, the better the mixing effect of the material.

[0003] The mixing legs need to have a certain strength and rigidity to ensure that they can transmit a large torque during heavy-load operations, remain unchanged at high temperatures, have good wear resistance, and have a service life of 800~1000h. Currently, the mixing legs of almost all thermal regeneration maintenance equipment often need to mix materials with larger particles. If the larger particles cannot be broken in a short period of time, it may cause wear of the mixing legs in the long run. How to increase the service life of the legs, improve operating efficiency and simplify production and manufacturing has become the focus of technical research in the industry. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the stirring legs of almost all current thermal regeneration maintenance equipment often need to stir materials with larger particles. If the materials with larger particles cannot be broken in a short time, the stirring legs may be worn in the long term. The utility model provides an anti-wear structure.

[0005] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0006] An anti-wear structure comprises a stirring leg, wherein a stirring shoe and a wear-resistant plate are respectively arranged below and on one side of the stirring leg;

[0007] It also includes an assembly mechanism and a mounting mechanism. The assembly mechanism is used to assemble the stirring leg, the stirring shoe and the wear-resistant plate together.

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0022] The anti-wear structure provided in this embodiment is mainly used to solve the problem that the stirring legs of almost all current thermal regeneration maintenance equipment often need to stir materials with larger particles. If the materials with larger particles cannot be broken in a short time, the stirring legs may be worn in the long term. The following technical solutions are provided. Figure 1-Figure 4 Make a detailed description:

[0023] An anti-wear structure comprises a stirring leg 1 with a stirring shoe 2 and a wear-resistant plate 3 respectively arranged at the bottom and one side. When in use, the user needs to first assemble the stirring leg 1, the stirring shoe 2 and the wear-resistant plate 3 together through an assembly mechanism 4, and then install the stirring leg 1 at one end of the stirring main shaft of the vertical stirring kettle through an installation mechanism 5. In this way, when the user controls the stirring main shaft of the vertical stirring kettle to rotate, the stirring leg 1, the stirring shoe 2 and the wear-resistant plate 3 can be driven to rotate simultaneously. Several grooves 6 all arranged on the surface of the wear-resistant plate 3 can break up large pieces of material. The main components of the assembly mechanism 4 are: a first limiting groove 401 and a second limiting groove 402 respectively arranged on the surfaces of the stirring shoe 2 and the stirring leg 1. When in use When assembling the stirring leg 1, the user first slides the wear-resistant plate 3 into the inner wall of the first limiting groove 401, and then aligns the second limiting groove 402 with the wear-resistant plate 3 to embed the wear-resistant plate 3 into the second limiting groove 402, and installs the stirring leg 1 above the stirring shoe 2 through the limiting mechanism 7, thereby completing the assembly of the stirring leg 1, the stirring shoe 2, and the wear-resistant plate 3, wherein the main components of the installation mechanism 5 are: a plurality of fixing bolts 502. When installing the stirring leg 1 on the surface of the stirring shaft of the vertical stirring kettle, it is necessary to first fit the installation plate 501 fixedly installed on the surface of the stirring leg 1 on the surface of the stirring shaft, and then screw in a plurality of installation mechanisms to complete the installation of the stirring leg 1 on the surface of the stirring shaft of the vertical stirring kettle.

[0024] In the above scheme, a stirring leg 1 is arranged above the stirring shoe 2, and a wear-resistant plate 3 is arranged on one side of the stirring leg 1, so that when in use, the user can first assemble the stirring leg 1, the stirring shoe 2, and the wear-resistant plate 3 together through the assembly mechanism 4, and then install the stirring leg 1 at one end of the stirring main shaft of the vertical stirring kettle through the installation mechanism 5. When the vertical stirring kettle is used to stir the materials inside, the stirring main shaft can drive the stirring leg 1, the stirring shoe 2, and the wear-resistant plate 3 to rotate at the same time, thereby achieving stirring of the materials. In this process, the groove 6 can provide additional stirring during the stirring process. They can help break up the lumps of materials and promote the exchange and mixing of materials, so that the mixing process is more uniform and effective, and the large pieces of materials are usually broken into smaller and more uniform particles or powders. When these particles or powders contact the surface of the stirring equipment, they have less impact and friction than large pieces of materials. Because small particles or powders move more smoothly on the surface, they will not cause strong friction and impact like large pieces of materials, thereby reducing wear on the surface of the equipment.

[0025] In the above scheme, when assembling the stirring leg 1, the stirring boot 2 and the wear-resistant plate 3, it is necessary to first insert the wear-resistant plate 3 into the inner wall of the first limiting groove 401, align the second limiting groove 402 on the surface of the stirring leg 1 with the wear-resistant plate 3 and then embed the wear-resistant plate 3 therein, and then thread the mounting bolt 702 into the surface of the stirring boot 2 and the limiting block 701, thereby realizing the assembly of the stirring leg 1, the stirring boot 2 and the wear-resistant plate 3. This assembly method realizes the installation of the stirring boot 2 and the wear-resistant plate 3 on the surface of the stirring leg 1 through a mounting bolt 702, and at the same time, the limiting effect of the wear-resistant plate 3 is also relatively good, thereby avoiding the shaking of the wear-resistant plate 3.

[0026] like Figures 1 to 4 As shown, in some embodiments, the main components of the limiting mechanism 7 are: a limiting block 701 fixedly installed at one end of the stirring leg 1, and a mounting bolt 702. When in use, the user inserts the wear-resistant plate 3 into the inner wall of the second limiting groove 402, slides the limiting block 701 into the top of the stirring shoe 2, and finally inserts the mounting bolt 702 into the surface of the stirring shoe 2 and the limiting block 701 in sequence, so that the stirring leg 1 can be limited above the stirring shoe 2 by the limiting block 701 on the inner wall of the stirring shoe 2. It should be noted that: the surface of the stirring leg 1 is provided with a sealing edge 8. After installation, the sealing edge 8 will fit on the surface of the stirring shoe 2 to achieve the sealing of the fitting part of the limiting block 701 and the stirring shoe 2. At the same time, the surface of the wear-resistant plate 3 is provided with a plurality of fillets 9, which can reduce the stress concentration at the edge of the groove 6 because the structure of the fillet 9 disperses the force more evenly. In contrast, a right angle will cause stress concentration at the sharp corners of the edge, which is prone to cracks and wear.

[0027] The working principle of this utility model:

[0028] First, the user inserts the wear-resistant plate 3 into the inner wall of the first limiting groove 401, embeds the wear-resistant plate 3 into the inner wall of the second limiting groove 402 on the surface of the stirring leg 1, and then screws in the mounting bolts 702 to assemble the entire device.

[0029] Secondly, after the user fits the mounting plate 501 onto the surface of the mounting flange on the surface of the stirring main shaft of the vertical mixing kettle, several fixing bolts 502 are screwed into the mounting plate 501 and then threaded into the surface of the mounting flange, thereby connecting the entire device and the stirring main shaft.
