The coal conveying system of cement plants is equipped with coal mills, which can be used to crush raw coal that does not meet the standards to meet the requirements of cement manufacturing. The important component of the coal mill is the grinding roller, which needs to use the grinding roller bearing during its rotation to facilitate the rotation of the grinding roller.

[0003] The grinding rollers of coal mills in the prior art are generally used in an environment with relatively high coal powder. After long-term use, a large amount of coal powder will adhere to the bearing surface. If the coal powder is not cleaned, it will easily enter the interior of the bearing after long-term use and cause damage to the bearing, thereby reducing the service life of the bearing.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Reference Figure 1-3 The utility model provides an embodiment: a grinding roller bearing of a coal mill for cement processing, comprising an inner ring 1 and an outer ring 8, the composition of the inner ring 1 and the outer ring 8 can form a relatively sealed installation space and rotation condition, the inner side of the inner ring 1 is fixedly connected with an anti-slip block 2, the function of the anti-slip block 2 is to prevent slipping and provide an installation space, the inside of the anti-slip block 2 is fixedly connected with a spring 3, the function of the spring 3 is to provide a pulling force, the other end of the spring 3 is fixedly connected with a limiting block 4, the limiting block 4 can play a limiting role, the side of the limiting block 4 away from the spring 3 is fixedly connected with a connecting column 5, the connecting column 5 can play a connecting role, the outside of the connecting column 5 is fixedly connected with a scraper 6, the function of the scraper 6 is to scrape off the coal powder on the outer ring 8;

[0034] Reference Figure 2 , Figure 4 and Figure 7Sealing ring grooves 7 are provided inside the opposite sides of the inner ring 1, and sealing rings 9 are fixedly connected to the opposite sides of the inner part of the outer ring 8. The cooperation between the sealing ring groove 7 and the sealing ring 9 can improve the sealing performance. The sealing ring 9 is rotatably connected to the inside of the sealing ring groove 7. A rolling mechanism 10 is provided inside the outer ring 8. The rolling mechanism 10 can reduce friction and is an important component of the bearing. A grinding roller 11 is detachably connected to the inner side of the inner ring 1, and an anti-skid groove 12 is provided inside the grinding roller 11. The anti-slip block 2 can cooperate with the anti-slip groove 12 to prevent the grinding roller 11 from slipping on the inner side of the inner ring 1.

[0035] Reference Figure 5-6 The rolling mechanism 10 includes two retaining rings 1001, which can play a role of fixing and retaining. The two retaining rings 1001 are arranged inside the outer ring 8. A connecting rod 1002 is rotatably connected between the two retaining rings 1001. The outside of the connecting rod 1002 is fixedly connected with a rolling body 1003. The connecting rod 1002 can be installed on the retaining ring 1001, and the rolling body 1003 can be installed through the connecting rod 1002. The rolling body 1003 can reduce the friction between the inner ring 1 and the outer ring 8, so that it can be rotated conveniently. The rolling body 1003 is arranged on the inner side of the top end of the inner ring 1, and the rolling body 1003 is arranged inside the outer ring 8.

[0036] Reference Figure 5-7 The anti-slip block 2 is slidably connected to the inside of the anti-slip groove 12, the scraper 6 is in contact with the outside of the outer ring 8, and the scraper 6 is close to the outside of the outer ring 8 to better clean the coal powder on the outside of the outer ring 8. The limit block 4 is slidably connected to the inside of the anti-slip block 2, and the connecting column 5 passes through the front side of the anti-slip block 2. The opposite sides of the sealing ring groove 7 are arranged on the opposite sides of the inner part of the outer ring 8. The opposite sides of the sealing ring groove 7 are arranged on the opposite sides of the inner part of the outer ring 8, which can make the sealing ring 9 slide inside the sealing ring groove 7, thereby improving the sealing performance. The vertical section of the limit block 4 is in the direction, and the vertical section of the inner groove of the anti-slip block 2 is square. Since the shapes of the limit block 4 and the inner groove of the anti-slip block 2 are both square, the limit block 4 can be limited so that the limit block 4 will not rotate inside the anti-slip block 2.

[0037] Working principle: When using, first align the anti-slip block 2 with the anti-slip groove 12 of the grinding roller 11, and insert the inner ring 1 into the outside of the grinding roller 11, so that the bearing can be installed on the grinding roller 11. When the grinding roller 11 rotates, since the outer ring 8 is fixed on another device, the rolling mechanism 10 can be used to reduce the friction when the grinding roller 11 rotates, so as to facilitate the rotation of the grinding roller 11, and when the grinding roller 11 rotates, it can drive the anti-slip block 2 to rotate, and when the anti-slip block 2 rotates, it can drive the limit block 4 to rotate, so as to drive the connecting column 5 to rotate, and when the connecting column 5 rotates When the scraper 6 is driven to rotate, the dust on the outer ring 8 can be scraped off, thereby cleaning the dust outside the outer ring 8. At the same time, the tension of the spring 3 can be used to pull the limit block 4 toward the inside of the anti-sliding block 2. The limit block 4 can drive the connecting column 5 to move toward the direction of the anti-sliding block 2, thereby driving the scraper 6 to move toward one side of the anti-sliding block 2, and then the scraper 6 can be pressed against the outside of the outer ring 8, thereby achieving a better cleaning effect. The cooperation of the sealing ring groove 7 and the sealing ring 9 can play a sealing role to prevent dust from entering the internal space formed by the outer ring 8 and the inner ring 1.
