Description

Technical Field

[0001] This utility model relates to the field of vibrating screen technology, and in particular to a premixed powder vibrating screen. Background Technology

[0002] A vibrating screen is a mechanical device that uses vibration to make materials reciprocate on the screen surface, thereby achieving functions such as material screening, grading, and impurity removal. It is widely used in many industries such as mining, metallurgy, building materials, chemicals, food, and medicine. Vibrating screens are generally driven by a vibrating motor or an ordinary motor, or by a self-vibrating source, which makes the screen body vibrate periodically in the direction of the excitation force. The material moves in a parabolic motion in a straight line on the screen surface. During the movement, materials smaller than the screen holes pass through the screen and fall down, while materials larger than the screen holes remain on the screen surface and continue to move, thereby achieving the purpose of screening.

[0003] A search of Chinese patent publication number "CN206184739U" reveals a "vibrating screen" that can use an air compressor to blow particles in the discharge channel to the outlet end, thereby improving the discharge efficiency of the vibrating screen.

[0004] Based on the above search and existing technology, it was found that the above patent has certain defects. When feeding material into the vibrating screen, it uses a conventional fixed feeding hopper. Therefore, the material will be concentrated in a certain part of the screen after feeding, so the screen in other areas of the vibrating screen is not fully utilized, resulting in a decrease in the overall screening rate and screening efficiency. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a premixed powder vibrating screen, which solves the technical problem of insufficient efficiency of existing vibrating screens.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A premixed powder vibrating screen includes a vibrating screen body, a cover plate at the upper end of the vibrating screen body, a feed hopper rotatably installed inside the cover plate, the feed hopper being installed to the cover plate via a sealed bearing, and a portion of the feed hopper being exposed above the cover plate.

[0010] A feeding structure is fixedly installed on the circumferential surface of the feeding hopper;

[0011] The feeding structure includes a first gear, a servo motor is fixedly installed inside the cover plate, a second gear is fixedly installed on the output shaft of the servo motor, the second gear meshes with the first gear, and an inclined pipe is fixedly installed at the lower end of the feeding hopper. The start of the servo motor can drive the second gear to rotate and mesh with the first gear, so that the feeding hopper drives the inclined pipe to rotate in the cavity between the vibrating screen body and the cover plate.

[0012] Preferably, the cover plate has a sliding groove inside, a sliding ring is slidably installed inside the sliding groove, the sliding groove is fixedly installed with the feed hopper, the sliding groove is located outside the second gear, and a ring plate is fixedly installed on the inner side of the cover plate.

[0013] Preferably, an internal gear is fixedly installed on the inner side of the cover plate, the ring plate and the internal gear are located between the vibrating screen body and the cover plate, a rotating joint is provided at the lower end of the inclined pipe, a discharge pipe is provided at the lower end of the rotating joint, a third gear is fixedly installed on the circumferential surface of the discharge pipe, and the third gear meshes with the internal gear.

[0014] (III) Beneficial Effects

[0015] Firstly, by setting up a feeding structure, when the premixed powder is discharged through the feeding hopper, the operator can first turn on the servo motor, so that the output shaft of the servo motor drives the second gear to rotate and mesh with the first gear. The first gear drives the feeding hopper to rotate, which in turn drives the inclined pipe, rotating joint and discharge pipe to rotate between the vibrating screen body and the cover plate to discharge the material. This increases the regional unit time screening capacity, and the premixed powder can pass through the screen faster, reducing screening time and thus improving the efficiency of the entire production process.

[0016] Secondly, when the inclined pipe rotates between the vibrating screen body and the cover plate, the third gear on the discharge pipe will mesh with the internal gear, thereby driving the discharge pipe to rotate synchronously. This allows the discharge pipe to evenly spread the premixed powder onto various parts of the screen inside the vibrating screen body, further increasing the regional screening capacity per unit time and improving work efficiency.

[0024] This application provides a premixed powder vibrating screen, effectively solving the technical problem of insufficient efficiency in existing vibrating screens. By setting up a feeding structure, when the operator discharges the premixed powder through the feed hopper, they can first turn on the servo motor. The output shaft of the servo motor drives the second gear to rotate and mesh with the first gear. The first gear drives the feed hopper to rotate, which in turn drives the inclined pipe, rotating joint, and discharge pipe to rotate and discharge the material between the vibrating screen body and the cover plate. This increases the regional unit time screening throughput, allowing the premixed powder to pass through the screen faster, reducing screening time and improving the efficiency of the entire production process. Furthermore, when the inclined pipe rotates between the vibrating screen body and the cover plate, the third gear on the discharge pipe will mesh with the internal gear, causing the discharge pipe to rotate synchronously. This allows the discharge pipe to evenly distribute the premixed powder onto various parts of the screen inside the vibrating screen body, further increasing the regional unit time screening throughput and improving work efficiency. Example

[0025] like Figure 1 - Figure 5 As shown, the technical solution in this application embodiment effectively solves the technical problem of insufficient efficiency of existing vibrating screens. The overall idea is as follows:

[0026] To address the problems existing in the prior art, this utility model provides a premixed powder vibrating screen, including a vibrating screen body 11, a cover plate 12 provided at the upper end of the vibrating screen body 11, a feed hopper 13 rotatably installed inside the cover plate 12, and part of the feed hopper 13 exposed above the cover plate 12.

[0027] A feeding structure is fixedly installed on the circumferential surface of the feed hopper 13;

[0028] The feeding structure includes a first gear 14, which is fixedly installed on the circumferential surface of the feeding hopper 13. A servo motor 15 is embedded and fixedly installed inside the cover plate 12. A second gear 16 is fixedly installed on the output shaft of the servo motor 15. The second gear 16 meshes with the first gear 14. An inclined pipe 17 is fixedly installed at the lower end of the feeding hopper 13. The inclined pipe 17 is a double-ended bend. The two ends of the inclined pipe 17 are exposed above the cover plate 12 and inside the cover plate 12, respectively. The end of the inclined pipe 17 exposed above the cover plate 12 is fixedly installed with the feeding hopper 13. The start of the servo motor 15 can drive the second gear 16 to rotate and mesh with the first gear 14, so that the feeding hopper 13 drives the inclined pipe 17 to rotate in the cavity between the vibrating screen body 11 and the cover plate 12.

[0029] By setting up a feeding structure, when the premixed powder is discharged through the feed hopper 13, the operator can first turn on the servo motor 15, so that the output shaft of the servo motor 15 drives the second gear 16 to rotate and mesh with the first gear 14. The first gear 14 drives the feed hopper 13 to rotate, which in turn drives the inclined pipe 17, the rotating joint 23 and the discharge pipe 24 to rotate and discharge the material between the vibrating screen body 11 and the cover plate 12. This increases the regional unit time screening capacity, and the premixed powder can pass through the screen faster, reducing screening time and thus improving the efficiency of the entire production process.

[0030] The cover plate 12 has a sliding groove 18 inside, and a slip ring 19 is slidably installed inside the sliding groove 18. The servo motor 15, the first gear 14 and the second gear 16 are all located inside the slip ring 19. The sliding groove 18 is fixedly installed with the feed hopper 13. The sliding groove 18 is located outside the second gear 16. A ring plate 21 is fixedly installed inside the cover plate 12.

[0031] By setting the slide groove 18 and the slip ring 19, the output shaft of the servo motor 15 drives the second gear 16 to rotate and mesh with the first gear 14. When the first gear 14 drives the feed hopper 13 to rotate, the feed hopper 13 will drive the slip ring 19 to slide inside the slide groove 18, thereby providing additional stability.

[0032] An internal gear 22 is fixedly installed on the inner side of the cover plate 12. The ring plate 21 and the internal gear 22 are located between the vibrating screen body 11 and the cover plate 12. A rotating joint 23 is provided at the lower end of the inclined pipe 17. One end of the inclined pipe 17 exposed on the inner side of the cover plate 12 is rotatably installed with the rotating joint 23. A discharge pipe 24 is provided at the lower end of the rotating joint 23. A third gear 25 is fixedly installed on the circumferential surface of the discharge pipe 24. The third gear 25 meshes with the internal gear 22.

[0033] When the inclined pipe 17 rotates between the vibrating screen body 11 and the cover plate 12, the third gear 25 on the discharge pipe 24 will mesh with the internal gear 22, thereby driving the discharge pipe 24 to rotate synchronously. This allows the discharge pipe 24 to evenly spread the premixed powder onto various parts of the screen inside the vibrating screen body 11, further increasing the regional screening throughput per unit time and improving work efficiency.

[0034] Working principle:

[0035] The first step is to start the servo motor 15 when using it. The output shaft of the servo motor 15 drives the second gear 16 to rotate and mesh with the first gear 14. The first gear 14 drives the feed hopper 13 to rotate, which in turn drives the inclined pipe 17, the rotating joint 23 and the discharge pipe 24 to rotate and discharge material between the vibrating screen body 11 and the cover plate 12.

[0036] In the second step, when the inclined pipe 17 rotates between the vibrating screen body 11 and the cover plate 12, the third gear 25 on the discharge pipe 24 will mesh with the internal gear 22, thereby driving the discharge pipe 24 to rotate synchronously, so that the discharge pipe 24 can evenly sprinkle the premixed powder onto various parts of the screen inside the vibrating screen body 11.

[0037] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
