[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way serves as any limitation on the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0042] like Figures 1 to 5 As shown, an embodiment of the present invention provides a coal slag screening device, including a screening frame 1, a fixed plate 2, a screening mechanism 3 and a vibrating part 4, the screening mechanism 3 is movably arranged in the screening frame 1, the fixed plate 2 is fixed to the top of the screening frame 1, the vibrating part 4 is installed on the fixed plate 2, the vibrating part 4 and the screening mechanism 3 are driven and connected so that the screening mechanism 3 can screen the coal slag through vibration; wherein, the screening mechanism 3 includes a screening plate 31, a mounting frame 33 and a clamping structure, the mounting frame 33 is movably installed in the screening frame 1, the screening plate 31 and the sliding groove of the mounting frame 33 are slidably matched, and the screening plate 31 is detachably clamped to the mounting frame 33 through the clamping structure; there are multiple screening plates 31, and the apertures of the sieve holes of the multiple screening plates 31 are different, so that different screening plates 31 can be replaced on the mounting frame 33 as needed.

[0043] In this solution, the screen plate 31 can be quickly assembled and disassembled by the snap-fitting operation of the snap-fitting structure and the sliding movement of the screen plate 31. In this way, the screen plates 31 of different apertures can be quickly replaced on the mounting frame 33 according to the needs of use, thereby improving production efficiency and reducing the maintenance frequency caused by hole blockage. Of course, this coal slag screening device can also be used for screening coal gangue or other materials.

[0044] like Figures 2 to 4 As shown, the clamping structure includes a clamping ring 32 installed on the screen plate 31 and a clamping block 37 movably installed on the screen frame 1, the clamping ring 32 has a clamping groove, and the clamping block 37 can be clamped into the clamping groove or disengaged from the clamping groove; when the clamping block 37 is clamped into the clamping groove, the screen plate 31 and the mounting frame 33 are connected; when the clamping block 37 is disengaged from the clamping groove, the screen plate 31 can be pulled out from the sliding groove of the mounting frame 33.

[0045] Through the above arrangement, the clamping block 37 can be engaged with or separated from the clamping slot by simply moving the clamping block 37 , thereby realizing rapid assembly and disassembly of the screening plate 31 .

[0046] The clamping structure further includes a spring 36 and a button 38. The lower end of the spring 36 cooperates with the mounting bracket 33, and the upper end of the spring 36 cooperates with the clamping block 37. The button 38 is installed above the clamping block 37. When the button 38 is pressed, the clamping block 37 moves downward and disengages from the slot.

[0047] The button 38 is provided to facilitate operation. The spring 36 is used to apply a thrust to the block 37 without disassembling the screening plate 31, so that the block 37 and the groove of the snap ring 32 remain engaged, thereby ensuring the reliability of the connection.

[0048] like Figure 3 As shown, the clamping structure further includes a limiting tube 35 , the lower end of which is fixed to the mounting bracket 33 , and a portion of the spring 36 is located inside the limiting tube 35 .

[0049] The limiting tube 35 limits the radial position of the spring 36 and guides the spring 36 to prevent the block 37 from deflecting.

[0050] Furthermore, the mounting frame 33 and the screening frame 1 have space to avoid the button 38, and the block 37 avoids the sliding path of the screening plate 31. Through the above arrangement, space for personnel operation is provided, and interference affecting the operation is avoided.

[0051] like Figure 3 As shown, the clamping block 37 includes a base plate and a first block and a second block spaced apart on the base plate. The base plate is connected to the upper end of the spring 36. The first block is used to cooperate with the clamping slot. The button 38 is installed on the second block. The space between the first block and the second block is used to avoid the physical structure of the clamping ring 32.

[0052] Furthermore, a guiding slope can be provided on the first block, so that during installation, after the screening plate 31 and the snap ring 32 are pushed into place, the first block and the snap ring 32 are automatically engaged under the guidance of the guiding slope, further improving the convenience of operation.

[0053] Through the above arrangement, the space between the first block and the second block is used to avoid the physical structure of the clamping ring 32, avoiding interference and ensuring that the first block is locked into the clamping groove. The clamping block 37 can be set as an integrated structure to ensure structural strength.

[0054] like Figure 1 and Figure 2As shown, there are two mounting brackets 33 arranged opposite to each other, and the screening plate 31 is located between the two mounting brackets 33. There are two clamping structures, and the two clamping structures are respectively arranged corresponding to the two mounting brackets 33. The two mounting brackets 33 can better support and limit the screening plate 31 to ensure stability.

[0055] like Figure 2 and Figure 3 As shown, the screening mechanism 3 also includes an elastic member 34, the lower end of the elastic member 34 is mounted on a supporting block protruding from the inner wall of the screening frame 1, and the upper end of the elastic member 34 is connected to the mounting frame 33. Through the cooperation of the elastic member 34 and the vibrating part 4, the mounting frame 33 and the screening plate 31 are vibrated.

[0056] Through the above arrangement, the mounting frame 33 and the screening plate 31 can be supported and the mounting frame 33 and the screening plate 31 can be vibrated to screen the coal slag.

[0057] Furthermore, the two mounting brackets 33 are arranged opposite to each other, the screening plate 31 is located between the two mounting brackets 33, and the elastic members 34 are multiple, and the multiple elastic members 34 are distributed at different positions of the two mounting brackets 33. The multiple elastic members 34 improve the structural stability, increase the load-bearing capacity of the screening plate 31, and ensure the screening effect.

[0058] like Figure 5 As shown, the vibrating unit 4 includes a vibrating unit 41, an output rod 42, and a connecting frame 43. The vibrating unit 41 is fixedly connected to the top of the fixed plate 2. One end of the output shaft of the vibrating unit 41 is fixedly connected to one end of the output rod 42, and the other end of the output rod 42 is fixedly connected to the top of the connecting frame 43. The bottom two sides of the connecting frame 43 are respectively fixedly connected to the top of the corresponding mounting frame 33. The vibrating unit 41 vibrates the mounting frame 33 and the screening plate 31, thereby screening the coal slag. The vibrating unit 41 can be an existing mature product, which is well known to those skilled in the art and does not require detailed explanation.

[0059] The working principle of the above embodiment is:

[0060] When the staff needs to replace the screen plate 31 with another filter hole size, they first press the two buttons 38. When the two buttons 38 are pressed, the block 37 is pushed to squeeze the spring 36. After being squeezed, the spring 36 is deformed toward the inner wall of the limiting tube 35. When the spring 36 contracts, the block 37 is moved, so that the limit between the block 37 and the snap ring 32 is released. When the limit between the snap ring 32 and the block 37 is released, the screen plate 31 is also released from the mounting bracket 33. The staff can then remove the screen plate 31 and replace another screen plate 31.

[0061] When installing other screen plates 31, first insert the side of the screen plate 31 without the retaining ring 32 into the mounting frame 33, and then continuously push the screen plate 31 so that the retaining rings 32 installed on both sides of the screen plate 31 are engaged with the retaining blocks 37 connected in the mounting frame 33, and the installation of the new screen plate 31 is completed.

[0062] Compared with the prior art, the beneficial effects of the present invention are:

[0063] 1. When the utility model is in use, through the installed screening mechanism, pressing two buttons at the same time can push the card block to squeeze the spring, thereby releasing the limit between the various components. This design not only simplifies the complexity of replacing the screening plate, but also makes the operation process more intuitive and easy to understand. The staff can quickly remove and install the screening plate, saving maintenance time and reducing the possibility of operational errors. At the same time, pressing buttons to control the movement of the spring and the card block can also effectively avoid accidental release or accidental operation during operation, thereby improving the safety of the staff. The clamping design between the clamping ring and the card block can also ensure that the screening plate is firmly installed to avoid loosening or damage due to vibration or changes in working environment conditions.

[0064] 2. When in use, the vibrator is connected to the output shaft and output rod by the installed vibrating unit, and then fixed to the mounting frame by the connecting frame, forming a stable overall structure. This design not only ensures the stability and reliability of the vibrator during operation, but also, through the fixed connection between the output shaft and output rod, the vibration can be effectively transmitted from the vibrator to the mounting frame and screening plate, thereby improving screening efficiency and quality.
