Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mining machinery, in particular to a wear-resistant guard plate for an ore discharge sleeve. Background Art
[0002] During the mining process, after the ore is mined, the slurry or ore needs to be discharged through the discharge system (such as discharge casing, conveying pipelines, etc.). These systems are often subjected to friction and impact from materials such as ore and gravel. Therefore, wear-resistant guards are needed to protect the pipes and equipment and prevent system failures caused by long-term wear. Discharge sleeve wear-resistant guards are usually installed on the inner wall of the discharge pipeline or in key locations, such as the slurry conveying pipeline and the inlet and outlet of the ore discharge pipeline. They can effectively resist the wear of ore and slurry on the equipment.
[0003] During use, some existing wear-resistant guards for discharge sleeves are usually directly installed by installing wear-resistant guards made of special materials on the outside of the conveyor belt or the inlet and outlet of the discharge pipe to resist the wear of the equipment by ore and slurry. However, it is not taken into account that only protecting the conveyor belt or other parts of the device with special materials will result in a relatively simple protection effect, and can only prevent the wear of the equipment by ore and slurry, but cannot absorb the impact force caused by the ore and slurry on the device, thereby reducing the service life of the device.
[0004] Therefore, in view of the above problems, a wear-resistant guard plate for a discharge sleeve is proposed. Utility Model Content

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0030] Reference Figures 1 to 4 The utility model provides an embodiment: a wear-resistant guard plate for a discharge ore sleeve, comprising a containing shell 1, a cavity 2 is opened inside the containing shell 1, and a plurality of dampers 3 are fixedly connected to the bottom inner wall of the cavity 2, so that the bottom inner wall of the cavity 2 can provide support for the plurality of dampers 3, and a spring 4 is provided on the outer sleeve of the damper 3, and the top of the damper 3 is fixedly connected to the limiting plate 5, so that the limiting plate 5 will compress the damper 3 when the force is applied, and one end of the spring 4 is fixedly connected to the bottom inner wall of the cavity 2, and the other end of the spring 4 is fixedly connected to the bottom of the limiting plate 5, so that the limiting plate 5 will compress the spring 4 when the force is applied, The top of the positioning plate 5 is fixedly connected to a force transmission plate 6, and then the force transmission plate 6 will press the limit plate 5 when it is subjected to force. The top of the force transmission plate 6 is fixedly connected to a protection component for protecting the device, so that the protection component will press the force transmission plate 6 when it is subjected to force. A plurality of guide grooves 8 are provided on the top of the protection component, and then the ore can be moved in the direction of the guide groove 8 through the setting of the guide groove 8. The limit plate 5 is slidably connected to the inside of the cavity 2, and then the cavity 2 can provide a limit for the limit plate 5. The bottom of the force transmission plate 6 is slidably connected to the inside of the cavity 2, so that the cavity 2 can provide a limit for the force transmission plate 6.
[0031] The protection component includes a protective plate 7, which is made of ferrochrome, and the ferrochrome material has significant wear resistance, corrosion resistance and high temperature performance. The high chromium content in ferrochrome gives it extremely strong wear resistance, so it can effectively resist the friction and impact of materials such as ore and slurry, and extend the service life of the protective plate. In addition, the high hardness and toughness of ferrochrome enable it to maintain stable performance in high-impact and high-wear environments, adapting to the harsh working conditions of mine discharge systems. In addition, the corrosion resistance of this material can also prevent damage caused by corrosion from acid and alkali slurries, reducing maintenance and replacement frequency. The bottom of the protective plate 7 is fixedly connected to the top of the force transfer plate 6, so that the protective plate 7 will press the force transfer plate 6 when it is subjected to force, and multiple guide grooves 8 are all opened on the top of the protective plate 7;
[0032] Reference Figure 1 The bottom of the accommodating shell 1 is fixedly connected with a bottom plate 9, so that the accommodating shell 1 can be fixed by fixing the bottom plate 9. Two bolts 10 are provided on the left and right sides of the bottom plate 9. The bottoms of the multiple bolts 10 are threadedly connected with a mounting plate 11, and then the bottom plate 9 can be fixed to the top of the mounting plate 11 through the bolts 10. The bottom of the bottom plate 9 is in contact with the top of the mounting plate 11, and then the bottom plate 9 can be firmly mounted on the top of the mounting plate 11.
[0033] Working principle: First, during the discharge process, when the ore is discharged from the discharge sleeve, the ore first contacts the protective plate 7 in the protective assembly. A plurality of guide grooves 8 are provided on the top of the protective plate 7, which serve to guide the flow direction of the ore. The ore is discharged along the direction of the guide grooves 8, making the discharge of the ore more stable and orderly. When the ore presses the protective plate 7, the protective plate 7 begins to move downward due to the pressure of the ore, and the protective plate 7 moves downward while driving the force transmission plate 6 to move downward. When the force transmission plate 6 moves downward, it presses the limit plate 5, causing the limit plate 5 to slide in the cavity 2. After the limit plate 5 is pressed by the force transmission plate 6, it will compress the damper 3 and the spring 4. Then, during the compression process, the damper 3 and the spring 4 will absorb the impact force caused by the ore on the equipment. The damper 3 plays a role in buffering and shock absorption through its internal damping effect and the elastic deformation of the spring 4, reducing the damage of the impact force of the ore to the entire device and the ore discharge sleeve, thereby increasing the service life of the device.
[0034] And the material of the protective plate 7 is ferrochrome. Ferrochrome has significant wear resistance, corrosion resistance and high temperature performance. During the flow of slurry, the ore and slurry will cause friction and impact on the protective plate. Due to the high chromium content in ferrochrome, it has extremely strong wear resistance and can effectively resist such friction and impact, preventing damage to the protective plate body. In addition, the high hardness and toughness of ferrochrome enable it to maintain stable performance in high-impact and high-wear environments, adapting to the harsh working conditions of mine discharge systems. The corrosion resistance of this material can also prevent damage caused by corrosion from acid and alkali slurries, reduce maintenance and replacement frequency, and improve the durability of the device.
[0035] Therefore, when the device needs to be installed, the device can fix the base plate 9 on the top of the mounting plate 11 by means of bolts 10, so that the base plate 9 can be firmly mounted on the mounting plate 11, thereby achieving fixed installation of the entire discharge sleeve wear-resistant guard plate. During the discharge process, as the ore is continuously discharged and impacted, the discharge sleeve wear-resistant guard plate continues to play a role in protecting the discharge sleeve, guiding the discharge of ore, and absorbing impact force.
[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
