With the development of rotary kilns, the requirements for stones in stone calcination have increased, and the cleanliness requirements for stone screening screens have become increasingly stringent. In multi-frequency vibrating screens, the distance between the upper and lower layers during stone screening is only 30mm-40mm. Traditional cleaning methods, such as manual and mechanical cleaning, suffer from problems such as high labor intensity from manually removing maintenance ports, incomplete cleaning leading to poor air permeability in the rotary kiln preheater, and damage to the screens when cleaning with hard objects, all of which affect production efficiency. Utility Model Content
[0003] This utility model proposes a screen cleaning device for a multi-frequency vibrating screen, which solves the problems of traditional cleaning methods in related technologies, such as high labor intensity from manually removing the maintenance port, poor air permeability of the rotary kiln preheater due to incomplete cleaning, and easy damage to the screen by cleaning with hard objects, which affect production efficiency.
[0004] The technical solution of this utility model is as follows: A screen cleaning device for a multi-frequency vibrating screen, used for cleaning the lower screen of a vibrating screen, the key feature being: comprising,
[0005] The winding rope has its outer end located outside the vibrating screen and its inner end located above the lower screen mesh.
[0006] An elastic vibrating element is located above the lower screen and connected to the inner end of the take-up rope. After the take-up rope is released, the elastic vibrating element is used to fall onto the lower screen.
[0007] It also includes,
[0008] A positioning sleeve, which is connected to the inner end of the take-up and release rope;
[0009] A positioning plate is disposed on the elastic vibrating element, and there are two positioning plates, with the positioning sleeve located between the two positioning plates.
[0010] A locking bolt, which is simultaneously inserted into both the positioning sleeve and the positioning plate;
[0011] A locking nut is threadedly connected to the locking bolt, and two positioning plates are clamped between the nut of the locking bolt and the locking nut.
[0012] It also includes a positioning ring, which is connected to the outer end of the take-up and release rope.
[0013] It also includes,
[0014] A rotary drive mechanism is located outside the vibrating screen;
[0015] A drum is connected to the output shaft of the rotary drive mechanism, and a positioning ring is disposed on the drum.
[0016] It also includes an anti-detachment baffle, which is disposed around the drum, and the take-up and release rope is located between the anti-detachment baffle and the rotary drive mechanism.
[0017] One end of the lower screen is inclined upward along its length, and the roller is located above that end of the lower screen. The length of the roller is set along the width of the lower screen.
[0018] It also includes,

[0035] Example, refer to Figures 1-2 As an embodiment of this utility model, a screen cleaning device for a multi-frequency vibrating screen is proposed for cleaning the lower screen 14 of the vibrating screen. It includes a winding rope 1 and an elastic vibrating element 2. The outer end of the winding rope 1 is located outside the vibrating screen, and the inner end of the winding rope 1 is located above the lower screen 14. The elastic vibrating element 2 is located above the lower screen 14 and is connected to the inner end of the winding rope 1. After the winding rope 1 is released, the elastic vibrating element 2 is used to fall onto the lower screen 14.
[0036] In this embodiment, the outer end of the retractable rope 1 is located outside the vibrating screen, making it convenient for operators to control. When it is necessary to clean the lower screen 14, the retractable rope 1 is released, and the elastic vibrating element 2 falls onto the lower screen 14 under gravity. The vibration force generated by the vibrating screen itself is transmitted to the elastic vibrating element 2, causing the elastic vibrating element 2 to vibrate and clean the lower screen 14. The attached substances on the screen, such as dust and particles, are loosened and fall off. After cleaning, the retractable rope 1 is tightened, and the elastic vibrating element 2 is lifted back to its original position, ready for the next use.
[0037] Compared to traditional manual cleaning methods that require manually dismantling the inspection port, this invention allows for cleaning of the lower screen 14 simply by controlling the release and retraction of the rope 1. This significantly reduces labor intensity, eliminating the need for heavy physical labor and improving work efficiency. By changing the length of the released rope 1, the position of the elastic vibrator 2 can be altered, enabling it to thoroughly and effectively clean the screen. This avoids the incomplete cleaning issues common in traditional methods, improves the screen's permeability after cleaning, ensures the normal operation of the rotary kiln preheater, and increases production efficiency. Because the elastic vibrator 2 is elastic, it does not damage the lower screen 14 during cleaning, unlike hard objects, thus extending the screen's lifespan and reducing equipment maintenance costs.
[0038] Furthermore, such as Figure 1As shown, it also includes a positioning sleeve 3, a positioning plate 4, a locking bolt 5, and a locking nut 6. The positioning sleeve 3 is connected to the inner end of the take-up rope 1. The positioning plate 4 is set on the elastic vibrating component 2, and there are two positioning plates 4. The positioning sleeve 3 is located between the two positioning plates 4. The locking bolt 5 is inserted into both the positioning sleeve 3 and the positioning plate 4. The locking nut 6 is threadedly connected to the locking bolt 5, and the two positioning plates 4 are clamped between the nut of the locking bolt 5 and the locking nut 6. Through the cooperation of the locking bolt 5 and the locking nut 6, the positioning sleeve 3 and the two positioning plates 4 are locked together, which can realize the firm connection between the elastic vibrating component 2 and the take-up rope 1, ensuring that the elastic vibrating component 2 will not detach from the take-up rope 1 during the cleaning process, and ensuring that the cleaning process can be carried out stably and reliably. The locking bolt 5 and the locking nut 6 are detachably connected, the connection is firm and reliable, and the disassembly and assembly are convenient and quick, saving time and effort, and facilitating the replacement of elastic vibrating components 2 of different specifications.
[0039] Furthermore, such as Figure 1 and Figure 2 As shown, it also includes a positioning ring 7, which is connected to the outer end of the take-up and release rope 1. The positioning ring 7 facilitates the positioning of the outer end of the take-up and release rope 1, making it easier to take up and release the rope 1.
[0040] Furthermore, such as Figure 2 As shown, the system also includes a rotary drive mechanism 8 and a drum 9. The rotary drive mechanism 8 is located outside the vibrating screen. The drum 9 is connected to the output shaft of the rotary drive mechanism 8, and a positioning ring 7 is mounted on the drum 9. When the rotary drive mechanism 8 operates, it drives the drum 9 to rotate, thereby realizing the winding and unwinding operation of the rope 1. By controlling the forward and reverse rotation of the drum 9, the winding and unwinding length of the rope 1 can be precisely controlled, thereby adjusting the position of the elastic vibrating element 2 on the lower screen 14. This can replace manual operation, realize automated control of the winding and unwinding of the rope 1, further reduce labor intensity, and improve work efficiency.
[0041] Furthermore, such as Figure 2 As shown, it also includes an anti-detachment baffle 10, which is disposed around the drum 9. The take-up and release rope 1 is located between the anti-detachment baffle 10 and the rotary drive mechanism 8. The anti-detachment baffle 10 can prevent the take-up and release rope 1 from falling off the drum 9, ensuring a reliable connection between the take-up and release rope 1 and the drum 9, and ensuring the normal operation of the device.
[0042] Furthermore, such as Figure 2As shown, one end of the lower screen 14 is inclined upwards along its length, and the drum 9 is located above this end of the lower screen 14. The length of the drum 9 is set along the width of the lower screen 14. This arrangement allows the elastic vibrator 2 to fall naturally along the inclined direction of the screen when the winding rope 1 is released. This optimizes the falling path of the elastic vibrator 2, enabling it to more effectively cover all parts of the lower screen 14 and improve the cleaning effect. For example, first, the take-up rope 1 is extended by 50cm, then the rotary drive mechanism 8 stops working, causing the elastic vibrating element 2 to clean the lower screen 14 at a distance of 50cm from the top. After 20 seconds, the rotary drive mechanism 8 starts working again, extending the take-up rope 1 by another 50cm, and then stops working, causing the elastic vibrating element 2 to clean the lower screen 14 at a distance of 100cm from the top. After 20 seconds, the rotary drive mechanism 8 starts working again, extending the take-up rope 1 by another 50cm, and then stops working, causing the elastic vibrating element 2 to clean the lower screen 14 at a distance of 150cm from the top. The length of the take-up rope 1 extended each time and the dwell time of the elastic vibrating element 2 at each position can be adjusted according to actual needs to better meet cleaning requirements.
[0043] Furthermore, such as Figure 2 and Figure 3 As shown, the system also includes a camera 11 and a control module 12. The camera 11 is mounted on the vibrating screen and positioned above the lower screen 14, with its imaging end facing the lower screen 14. The output end of the camera 11 is connected to the input end of the control module 12, and the output end of the control module 12 is electrically connected to the rotary drive mechanism 8. The camera 11 is installed on the screen body of the vibrating screen and positioned between the upper and lower screens 14. The camera 11 monitors the status of the lower screen 14 in real time and sends the captured images to the control module 12. Based on the image information captured by the camera 11, the control module 12 determines whether the lower screen 14 needs cleaning. When cleaning is required, the control module 12 activates the rotary drive mechanism 8, releasing the take-up rope 1 and allowing the elastic vibrating element to fall onto the lower screen 14 for cleaning. This system enables intelligent cleaning control, allowing for timely detection of deposits on the screen without frequent manual checks of the lower screen 14, ensuring timely and effective cleaning.
[0044] Furthermore, such as Figure 2 and Figure 3As shown, it also includes a limit switch 13, which is located above the upper end of the lower screen 14. The output of the limit switch 13 is electrically connected to the control module 12. When the take-up rope 1 needs to be retracted, the elastic vibrator 2 gradually approaches the limit switch 13. When the elastic vibrator 2 returns to its initial position, it triggers the limit switch 13. After receiving the signal, the control module 12 stops the rotary drive mechanism 8, ensuring that the elastic vibrator 2 accurately stays in its initial position. This prevents the elastic vibrator 2 from being over-lifted, ensuring the safe operation of the device.
[0045] Furthermore, the diameter of the elastic vibrator 2 is 9-23mm. For example, the diameter of the elastic vibrator 2 is 9mm, 13mm, 16mm, 19mm, or 23mm. The appropriate diameter of the elastic vibrator 2 can be selected according to the specifications of different lower screens 14 and cleaning requirements to achieve the best cleaning effect.
[0046] Furthermore, the elastic vibrating element 2 is a solid sphere molded from polyurethane polymer material. Polyurethane material has high elasticity and strength, generating a certain impact force for cleaning when in contact with the lower screen 14, without damaging the lower screen 14. This effectively protects the lower screen 14 and extends its service life. Moreover, its good elasticity allows the elastic vibrating element 2 to better adapt to the vibration of the lower screen 14, improving the cleaning effect.
[0047] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
