[0020] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0021] Example: Figure 1-4 As shown, an environmentally friendly dust-proof structure for a cement silo includes a cement silo 1, a dust-proof box 2 is fixedly connected to the top of the cement silo 1, a plurality of fixed blocks 15 are fixedly connected to the top of the internal top of the cement silo 1, a first spring 14 is fixedly connected to the top of the plurality of fixed blocks 15, a filter plate 11 is fixedly connected to the top side of the filter plate 11, a plurality of hemispherical protrusions 13 are fixedly connected, a pair of scraping rods 10 are fixedly connected to the inside of the dust-proof box 2, and the bottom of the scraping rod 10 is set at the top of the filter plate 11, the pair of scraping rods 10 are symmetrically arranged, and the pair of scraping rods 11 are fixedly connected. 0 is provided with a driving mechanism, the interior of the cement silo 1 is fixedly connected to a mounting ring 12, the interior of the mounting ring 12 is installed with a sieve plate 16, the right side of the cement silo 1 is fixedly connected to a fan 6, the output end of the fan 6 is fixedly connected to an exhaust pipe 7, and the top of the exhaust pipe 7 is connected to the dustproof box 2, the outer bottom of the cement silo 1 is fixedly connected to a connecting ring 3, the outer side of the connecting ring 3 is fixedly connected to a plurality of brackets 4, a reinforcing plate 5 is provided between two adjacent brackets 4, the hemispherical protrusions 13 correspond to the first springs 14 one by one, are evenly arranged along the circumference, and the number is an even number;

[0022] Cement enters the cement silo 1 from the feed port, and the fan 6 works to reduce the air pressure in the cement silo 1 through the exhaust pipe 7, so that the cement can enter the cement silo 1 smoothly. The filter plate 11 blocks the cement under the dust box 2. As the use time increases, the filter holes on the filter plate 11 are blocked by cement. At this time, the driving mechanism drives a pair of scraping rods 10 to make a circular motion inside the dust box 2, which can scrape off the cement dust on the inner wall of the dust box 2. In the process of the scraping rods 10 making a circular motion, they will act on the top of the filter plate 11. When the scraper rod 10 passes the hemispherical protrusion 13, the filter plate 11 is pressed downward by the hemispherical protrusion 13, so that the filter plate 11 moves downward and cooperates with the fixed block 15 to compress the first spring 14. When the scraper rod 10 passes over the hemispherical protrusion 13, the first spring 14 is reset to push the filter plate 11 up, so that the filter plate 11 collides with the scraper rod 10, and then the filter plate 11 vibrates, and the cement on the filter plate 11 is shaken off, which can maintain a good ventilation rate of the filter plate 11 and avoid affecting the operation of the fan 6.

[0023] Specifically, such as Figure 2 As shown, the driving mechanism includes a motor 8, and the motor 8 is fixedly connected to the top of the dustproof box 2. The output end of the motor 8 is arranged inside the dustproof box 2. The output end of the motor 8 is fixedly connected to a connecting rod 9, and the left and right ends of the connecting rod 9 are respectively fixedly connected to two scraper rods 10. The motor 8 drives the connecting rod 9 to rotate, and the rotating connecting rod 9 drives the scraper rods 10 at both ends to perform circular motion.

[0024] Specifically, such as Figure 2 and Figure 4 As shown, a telescopic tube 17 is fixedly connected to the outer side of the top of the sieve plate 16, and a connecting tube 18 is fixedly connected to the top of the telescopic tube 17, and the top of the connecting tube 18 is fixedly connected to the inner wall of the cement silo 1. Since the sieve plate 16 swings in the mounting ring 12, a gap exists between the sieve plate 16 and the mounting ring 12, so that cement can directly pass through the sieve plate 16 through the gap, affecting the quality of cement in the cement silo 1. By providing the connecting tube 18, the outer diameter of the top of the connecting tube 18 is the same as the inner diameter of the cement silo 1. During the falling process, the cement enters the telescopic tube 17 through the connecting tube 18, and then falls onto the sieve plate 16, thereby preventing the cement from directly entering the cement silo 1 without passing through the sieve plate 16, thereby ensuring the quality of the cement in the cement silo 1.

[0025] Working principle: Cement enters the cement silo 1 from the feed port. The fan 6 works to reduce the air pressure in the cement silo 1 through the exhaust pipe 7, allowing the cement to enter the cement silo 1 smoothly. During the falling process, the cement enters the telescopic tube 17 through the connecting pipe 18 and then falls onto the screen plate 16. The vibrator 19 cooperates with the second spring 20 to make the screen plate 16 swing inside the mounting ring 12, playing a screening role, so that qualified cement falls into the interior of the cement silo 1;

[0026] As the use time increases, the filter holes on the filter plate 11 are clogged with cement. At this time, the driving mechanism drives a pair of scraper rods 10 to perform circular motion inside the dust box 2, which can scrape off the cement dust on the inner wall of the dust box 2, and in the process of the scraper rods 10 performing circular motion, it will act on the hemispherical protrusion 13 at the top of the filter plate 11. When the scraper rods 10 pass the hemispherical protrusion 13, the hemispherical protrusion 13 squeezes the filter plate 11 downward, causing the filter plate 11 to move downward and cooperate with the fixed block 15 to compress the first spring 14. When the scraper rods 10 pass over the hemispherical protrusion 13, the first spring 14 resets and pushes the filter plate 11 up, causing the filter plate 11 to collide with the scraper rods 10, thereby causing the filter plate 11 to vibrate, shaking off the cement on the filter plate 11, and maintaining a good ventilation rate for the filter plate 11.

[0027] Finally, it should be noted that the above description is merely 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 will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
