Description

Technical Field

[0001] This utility model relates to the field of vibrating screen technology, and in particular to a device for preventing clogging of vibrating screen mesh. Background Technology

[0002] In industries such as mining, chemical, and grain processing, vibrating screens are key equipment for material grading and screening. Their screening efficiency directly affects the overall production progress. However, in actual operation, materials are easily trapped in the screen holes due to moisture, viscosity, or particle size differences, causing screen blockage. This not only reduces the throughput but also affects the grading accuracy. As a core auxiliary component adapted to vibrating screens, the vibrating screen anti-clogging device can promptly remove trapped materials in the screen holes through mechanical impact, airflow purging, or high-frequency vibration, effectively maintaining screen transparency. This ensures continuous and stable screening operations, improves production efficiency, reduces wear on the screen caused by clogging materials, extends the screen's service life, and ensures accurate grading of materials according to the preset particle size, further improving product quality.

[0003] However, in existing technologies, when dealing with high-moisture materials for anti-clogging cleaning, these materials are prone to forming sticky clumps due to moisture adsorption, which adhere firmly to the inner wall of the screen holes. Existing anti-clogging devices mostly adopt a generalized design. The impact force and frequency of mechanical impact devices are mostly fixed values, which are difficult to break up tough wet material clumps. In addition, excessive force may cause the clumps to compact. The airflow intensity of airflow purging devices is limited and cannot penetrate the wet material layer adhering to the screen holes. It can only act on the surface of the screen, which means that the device cannot accurately deal with the clogging causes of high-moisture materials. The screen holes will be quickly blocked by wet material clumps, resulting in a sharp drop in material throughput and a significant reduction in screening efficiency. The blocked screen holes will damage the grading accuracy, allowing wet material clumps that do not meet the particle size requirements to be mixed into the finished product, affecting product quality. At the same time, the adhered wet material will continue to squeeze and wear the screen, accelerating the aging and damage of the screen and increasing the frequency of screen replacement.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0015] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0016] Example 1: As Figure 1 - Figure 6 As shown, this utility model provides a vibrating screen anti-clogging device, including a screening mechanism 1, an adjustment mechanism 2 fixedly connected to the upper part of the screening mechanism 1, an anti-clogging mechanism 3 fixedly connected to the lower part of the adjustment mechanism 2, the anti-clogging mechanism 3 being located above the screening mechanism 1, the screening mechanism 1 including a support component 11, a vibration component 12 installed on the upper part of the support component 11, a screening component 13 installed on the upper part of the vibration component 12, the adjustment mechanism 2 including a lifting component and a horizontal moving component, the lifting component and the horizontal moving component being fixedly connected, and the horizontal moving component being fixedly connected to the anti-clogging mechanism 3; The anti-clogging mechanism 3 includes a mounting frame 31, multiple gears 310, and a cleaning brush 311. A reciprocating drive assembly is fixedly connected to the upper part of the mounting frame 31. A connector 38 is fixedly connected to the output end of the reciprocating drive assembly. A rack 39 is fixedly connected to the end of the connector 38. The rack 39 is slidably connected to the inside of the mounting frame 31. Multiple gears 310 are evenly distributed on the surface of the mounting frame 31 and are rotatably connected to the mounting frame 31. The gears 310 mesh with the rack 39. The cleaning brush 311 is fixedly connected to the bottom of the gears 310. A second limit frame 312 is fixedly connected to the upper part of the mounting frame 31. The side of the rack 39 is slidably connected to the second limit frame 312.

[0017] The specific settings and functions of this embodiment are described below: During screening, the support component 11 of the screening mechanism 1 provides the installation foundation for the whole, and the vibration component 12 drives the upper screening component 13 to vibrate to achieve material classification; the adjustment mechanism 2 adjusts the height through the lifting component and adjusts the lateral position through the horizontal movement component, so that the anti-blocking mechanism 3 accurately corresponds to the screen area of ​​the screening component 13, and the second limit frame 312 ensures the sliding stability of the rack 39; the reciprocating drive component of the anti-blocking mechanism 3 drives the connector 38 to reciprocate, and the connector 38 pulls the rack 39 to slide in the mounting frame 31. The rack 39 meshes with multiple evenly distributed gears 310, driving the gears 310 to rotate synchronously, thereby driving the cleaning brush 311 at the bottom of the gear 310 to rotate. The rotating cleaning brush 311, in conjunction with the vibration of the screening component 13, performs targeted cleaning of the high-humidity sticky agglomerated material on the screen surface and the inner wall of the screen holes.

[0018] The rotation of the cleaning brush 311 and the vibration of the screening component 13 work together to precisely break up tough clumps formed by high-moisture materials, while scraping away wet material adhering to the inner wall of the screen holes.

The lifting and horizontal moving components of the adjusting mechanism 2 can flexibly adjust the position of the anti-clogging mechanism 3 to ensure that the cleaning brush 311 fully covers the screen and avoids local clogging. The meshing transmission of the gear 310 and the rack 39 ensures that the rotation force of the cleaning brush 311 is uniform. It will not compact clumps due to excessive force, nor will it damage the screen. This effectively ensures the material throughput and screening efficiency, ensures that the grading accuracy is not affected, reduces screen wear, extends its service life, eliminates the need for frequent shutdowns for cleaning, and ensures production continuity.

[0019] Example 2: Figure 1 - Figure 5 As shown, the lifting assembly includes a fixed plate 21, which is fixedly connected to the side of the screening assembly 13. An electric telescopic rod 22 is fixedly connected to the upper part of the fixed plate 21, and a connecting frame 23 is fixedly connected to the upper part of the electric telescopic rod 22. The horizontal movement assembly includes two slide rails 24, both of which are fixedly connected to the connecting frame 23. A slider 25 is slidably connected inside each of the two slide rails 24. A first motor 26 is fixedly connected to the end of one slide rail 24, and a lead screw 27 is fixedly connected to the output end of the first motor 26.

The device includes a fixed frame 32, which is fixedly connected to the mounting frame 31. A drive wheel 34 is rotatably connected to the upper part of the fixed frame 32. A second motor 33 is installed at the center of one side of the drive wheel 34, and a reciprocating connecting rod 35 is rotatably connected to the eccentric part of the other side of the drive wheel 34. The second motor 33 is fixedly connected to the upper part of the fixed frame 32. A reciprocating drive rod 37 is movably connected to the end of the reciprocating connecting rod 35.

The first limit frame 36 is fixedly connected to the fixed frame 32. The end of the reciprocating drive rod 37 is fixedly connected to the connector 38.

[0020] The overall effect of this embodiment is that the support component 11 of the screening mechanism 1 provides the installation foundation, the vibration component 12 drives the screening component 13 to vibrate and achieve material classification; in the adjustment mechanism 2, the fixing plate 21 fixes the lifting component and the screening component 13, the electric telescopic rod 22 extends and retracts to drive the connecting frame 23 to rise and fall, thereby adjusting the height of the anti-blocking mechanism 3, the first motor 26 of the horizontal moving component drives the lead screw 27 to rotate, the lead screw 27 is threadedly engaged with the slider 25, driving the slider 25 to slide along the slide rail 24, thereby realizing the lateral position adjustment of the anti-blocking mechanism 3; the second... Motor 33 drives drive wheel 34 to rotate. Reciprocating connecting rod 35 at the eccentric part of drive wheel 34 pulls reciprocating drive rod 37, which makes reciprocating linear motion under the guidance of first limit frame 36. Reciprocating drive rod 37 drives rack 39 through connector 38, which slides along mounting frame 31 under the constraint of second limit frame 312. Rack 39 meshes with multiple gears 310 for transmission. Cleaning brush 311 at the bottom of drive gear 310 rotates synchronously. The rotating cleaning brush 311 cooperates with the vibration of screening component 13 to clean the high-humidity sticky agglomerated material on the screen surface and the inner wall of the screen hole.

[0021] By adjusting the transmission structure of the electric telescopic rod 22 and the lead screw 27 of the adjustment mechanism 2, the height and lateral position of the anti-clogging mechanism 3 can be precisely adjusted to ensure that the cleaning brush 311 fully covers the screen area and avoids local clogging of high-humidity materials. The reciprocating drive component adopts a combination of motor 33, drive wheel 34 and eccentrically connected reciprocating connecting rod 35, and with the guidance of limit frame 36, the rack 39 reciprocates stably and with controllable force, driving the cleaning brush 311 to rotate evenly. This can not only efficiently break up the tough clumps of high-humidity materials, but also thoroughly scrape off the wet material adhering to the inner wall of the screen holes, solving the problem of insufficient anti-clogging targeting in existing technologies. The entire transmission structure has moderate force and will not compact clumps or damage the screen, effectively improving the material throughput and screening efficiency, ensuring grading accuracy, reducing screen wear and replacement frequency, and eliminating the need for frequent shutdowns for cleaning, further ensuring production continuity.
