Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sieve plates, in particular to a high-efficiency anti-escape combined sieve plate. Background Art
[0002] The anti-runaway coarse screen plate is a device used in the vibrating screen to prevent large particles from passing through the screen plate and entering the undersize material without being fully screened.
[0003] The sieve plate is a consumable. When screening materials, the sieve plate will wear out, especially the middle part of the sieve plate. Compared with the two sides of the sieve plate, the wear is more serious. When the sieve plate is worn, coarse material often appears, and the material cannot be screened normally according to demand. The screen on the sieve plate needs to be maintained and replaced. Most of the existing screens use an integrated screen, which is not only inconvenient to replace, but also the wear conditions of the middle and both sides of the screen are different, which directly causes a waste of resources for the overall replacement of the screen.
[0004] Therefore, this application provides a high-efficiency anti-escape coarse combined sieve plate to meet the needs. Utility Model Content
[0005] The purpose of this application is to provide an efficient anti-coarseness combined screen plate, aiming to solve the problem that different screen wear conditions easily cause material coarseness, and directly replacing the screen as a whole is time-consuming and labor-intensive, and also causes waste of resources.
[0006] To achieve the above-mentioned purpose, the present application provides the following technical solution: a high-efficiency anti-runaway coarse combined screen plate, comprising a screen frame and a screen mesh, wherein the screen frame is a rectangular frame, a support rod for supporting the screen mesh is provided at the bottom of the screen frame, the screen mesh is laid on the support rod, and the screen frame is further provided with a convex edge corresponding to the position of the screen mesh;
[0007] The screen frame is also provided with a longitudinal pressure plate and a transverse pressure plate for pressing and limiting the screen mesh. The longitudinal pressure plate and the transverse pressure plate are spliced into a well-shaped frame to press and limit the screen mesh. The longitudinal pressure plate and the transverse pressure plate for pressing and limiting the screen mesh are set on the screen frame, which can fully fix and limit the combined screen mesh to avoid loosening during use.
[0008] Preferably, the screen is a combined structure and is made of polyurethane material. The screen is provided with three groups, which are arranged in sequence on the support rods of the screen frame. A combined screen is used and is longitudinally arranged on the screen frame. When screening the material, if the screen in the middle part is severely worn, only the screen in the middle part can be replaced, and the screens on both sides can still be used, saving resources.
[0009] Preferably, longitudinal pressing grooves adapted to the longitudinal pressing plates and the convex edges are formed in the screen mesh, and transverse pressing grooves adapted to the transverse pressing plates are also formed in the screen mesh. With the cooperation of the clamping blocks and the convex edges, only the two groups of longitudinal pressing plates need to be limited in position, and the pressing and limiting of the entire screen mesh can be completed, saving the time for the staff to replace the screen mesh and improving work efficiency.
[0010] Preferably, the transverse pressing plate is a "冂"-shaped plate, including a set of connecting plates and two groups of L-shaped plates, and the two groups of L-shaped plates are connected to both sides of the connecting plate.
[0011] Preferably, the longitudinal pressing plate is installed on the screen frame through bolts, and clamping blocks are further provided on the facing surfaces of the longitudinal pressing plate and the screen mesh. Card slots adapted to the clamping blocks are also formed at the facing ends of the L-shaped plates and the longitudinal pressing plate.
[0012] In summary, the technical effects and advantages of the present utility model are as follows:
[0013] In the present utility model, a combined screen mesh is adopted and longitudinally arranged on the screen frame. When screening materials, after the screen mesh in the middle part is severely worn, only the screen mesh in the middle part needs to be replaced, and the screen meshes on both sides can still be used continuously, saving resources; longitudinal pressing plates and transverse pressing plates for pressing and limiting the screen mesh are arranged on the screen frame, which can fully fix and limit the combined screen mesh and prevent it from loosening during use; with the cooperation of the clamping blocks and the convex edges, only the two groups of longitudinal pressing plates need to be limited in position, and the pressing and limiting of the entire screen mesh can be completed, saving the time for the staff to replace the screen mesh and improving work efficiency.
