Technical Field

[0001] The utility model relates to the technical field of papermaking pulp screening, in particular to a screen frame for separating papermaking fibers. Background Art

[0002] Paper is the most commonly used item in our daily life. Whether reading books, newspapers, writing, or painting, we have to come into contact with paper. Paper is a sheet-like fiber product used for writing, printing, painting, packaging, etc. It is generally made from an aqueous suspension of plant fibers that have been pulped, combined crosswise on a net, initially dewatered, and then compressed and dried.

[0003] During the process of papermaking production, in order to improve product quality, it is necessary to screen the pulp used for papermaking. At this time, a screening device will be used. However, during the screening process of the existing screening device, the pulp often gets stuck inside the screen holes, resulting in a low screening efficiency of the screen. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the technical problems in the above background, and to propose a screen frame for separating papermaking fibers.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme: A screen frame for separating papermaking fibers, including a U-shaped frame. Two support rods are fixedly installed on the side surface of the U-shaped frame. The surface of one end of the two support rods away from the U-shaped frame is fixedly installed with a feeding hopper. A temporary storage groove is opened on the inner bottom surface of the U-shaped frame. A discharge pipe is fixedly installed on the side surface of the U-shaped frame. The discharge pipe and the temporary storage groove are interconnected. A valve is fixedly installed on the outer wall surface of the discharge pipe. Two installation grooves are opened on the top surface of the U-shaped frame. Installation plates are movably installed inside the two installation grooves. A screen is fixedly installed between the two installation plates. A knocking device is arranged between the inner walls on both sides of the U-shaped frame. The knocking device includes a rotating rod. The rotating rod is rotatably connected between the inner walls on both sides of the U-shaped frame. A plurality of knocking rods are evenly fixedly installed on the outer wall surface of the rotating rod. The setting of the knocking rods plays an effect of patting the screen.

[0006] Preferably, a sliding groove is opened on one side surface of the U-shaped frame. A moving plate is slidably connected inside the sliding groove. A support plate is fixedly installed on one side surface of the U-shaped frame. An electric telescopic rod is fixedly installed on the surface of the support plate. The output end of the electric telescopic rod is fixedly connected with the moving plate. The setting of the electric telescopic rod plays an effect of driving the moving plate to move inside the sliding groove.

[0007] Preferably, a connecting plate is fixedly installed on the surface of the moving plate, a rack is fixedly installed on the surface of the end of the connecting plate away from the moving plate, a gear is fixedly installed on the outer wall surface of the rotating rod, and the rack and the gear are meshed with each other. The setting of the gear plays the role of driving the rotating rod to rotate.

[0008] Preferably, a limiting device is arranged on the top surface of the U-shaped frame. The limiting device includes a groove, the groove is opened on the top surface of the U-shaped frame, a slider is slidably connected inside the groove, a plug rod is fixedly installed on the surface of the slider, and a jack is opened on the side surface of one of the mounting plates. The settings of the plug rod and the jack play the role of limiting the mounting plate inside the mounting groove.

[0009] Preferably, a vertical rod is fixedly installed on the top surface of the U-shaped frame, a sliding ring is slidably connected to the surface of the vertical rod, a hinged plate is hinged to the annular side wall of the sliding ring, and one end of the hinged plate away from the sliding ring is hinged to the slider. The setting of the hinged plate plays the role of driving the slider to move inside the groove.

[0010] Preferably, a limiting plate is fixedly installed on the surface of the end of the vertical rod away from the U-shaped frame, and a spring is fixedly installed between the limiting plate and the sliding ring. The setting of the spring plays the role of restricting the position of the sliding ring on the surface of the vertical rod.

[0011] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0012] 1. In the present utility model, by setting a knocking device, when it is necessary to screen the slurry, first pour the slurry into the inside of the feeding hopper, then the slurry falls from the inside of the feeding hopper onto the surface of the sieve mesh, and then after being screened by the sieve mesh, it falls into the temporary storage tank. Then, when the sieve mesh is blocked during the screening process, turn on the electric telescopic rod. The electric telescopic rod starts to drive the moving plate to move inside the sliding groove. The moving plate moves inside the sliding groove to drive the connecting plate to move. The connecting plate moves to drive the rack to move. The rack moves and meshes with the gear, thereby causing the gear to rotate. The gear rotates to drive the rotating rod to rotate. The rotating rod rotates to drive the knocking rod to rotate, so that the knocking rod continuously beats the sieve mesh, causing the sieve mesh to vibrate, avoiding the sieve mesh from being blocked. Through the cooperation of the above structures, the knocking rod can beat the sieve mesh, causing the sieve mesh to vibrate, and thus enabling the sieve mesh to be used normally and ensuring that the screening efficiency is not affected.

[0013] 2. In the present utility model, by providing a limiting device, when the screen needs to be replaced, the sliding ring is slid, so that the sliding ring moves on the surface of the vertical rod. The movement of the sliding ring on the surface of the vertical rod will compress the spring, causing the spring to be compressed under force. At the same time, the movement of the sliding ring on the surface of the vertical rod also drives the articulated plate to move. The movement of the articulated plate pulls the slider to move inside the groove. The movement of the slider inside the groove drives the insertion rod to move, and the insertion rod moves to move itself out of the insertion hole. The separation of the insertion rod and the insertion hole causes the mounting plate to lose its limit inside the mounting groove. At this time, the screen can be moved, and the movement of the screen drives the mounting plate to move out of the mounting groove, thus completing the disassembly operation of the screen. Through the cooperation of the above structures, the screen can be disassembled, and then it is convenient to replace screens with different aperture sizes, so as to meet different screening production requirements.

However, the present utility model may be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0022] Please refer to Figures 1-4 , the present utility model provides a technical solution: a sieve frame for separating papermaking fibers, including a U-shaped frame 1. Two support rods 2 are fixedly installed on the side surfaces of the U-shaped frame 1. A blanking hopper 3 is fixedly installed on the surfaces of the two support rods 2 away from the U-shaped frame 1. A temporary storage groove 6 is opened on the inner bottom surface of the U-shaped frame 1. A discharge pipe 10 is fixedly installed on the side surface of the U-shaped frame 1. The discharge pipe 10 is communicated with the temporary storage groove 6. A valve 11 is fixedly installed on the outer wall surface of the discharge pipe 10. Two installation grooves 7 are opened on the top surface of the U-shaped frame 1. Installation plates 8 are movably installed inside the two installation grooves 7. A sieve mesh 9 is fixedly installed between the two installation plates 8.

[0023] Next, specifically describe the specific settings and functions of its knocking device 4 and limiting device 5.

[0024] In this embodiment: A knocking device 4 is provided between the inner walls on both sides of the U-shaped frame 1. The knocking device 4 includes a rotating rod 41. The rotating rod 41 is rotatably connected between the inner walls on both sides of the U-shaped frame 1. A plurality of knocking rods 42 are evenly fixedly installed on the outer wall surface of the rotating rod 41.

[0025] In this embodiment: The setting of the knocking rod 42 has the effect of patting the sieve mesh 9.

[0026] Specifically, a sliding groove 43 is opened on one side surface of the U-shaped frame 1. A moving plate 44 is slidably connected inside the sliding groove 43. A support plate 45 is fixedly installed on one side surface of the U-shaped frame 1. An electric telescopic rod 46 is fixedly installed on the surface of the support plate 45. The output end of the electric telescopic rod 46 is fixedly connected to the moving plate 44.

[0027] In this embodiment: The setting of the electric telescopic rod 46 has the effect of driving the moving plate 44 to move inside the sliding groove 43.

[0028] Specifically, a connecting plate 47 is fixedly installed on the surface of the moving plate 44. A rack 48 is fixedly installed on the surface of the connecting plate 47 away from the moving plate 44. A gear 49 is fixedly installed on the outer wall surface of the rotating rod 41. The rack 48 and the gear 49 are meshed with each other. The setting of the gear 49 has the effect of driving the rotating rod 41 to rotate.

[0029] In this embodiment: A limiting device 5 is provided on the top surface of the U-shaped frame 1. The limiting device 5 includes a groove 51 which is opened on the top surface of the U-shaped frame 1. A slider 52 is slidably connected inside the groove 51. A plug rod 53 is fixedly installed on the surface of the slider 52. A jack 54 is opened on the side surface of one of the mounting plates 8. When the screen 9 needs to be replaced, slide the sliding ring 56 so that the sliding ring 56 moves on the surface of the vertical rod 55. The movement of the sliding ring 56 on the surface of the vertical rod 55 will compress the spring 59, causing the spring 59 to be compressed under force. At the same time, the movement of the sliding ring 56 on the surface of the vertical rod 55 also drives the articulated plate 57 to move. The movement of the articulated plate 57 pulls the slider 52 to move inside the groove 51. The movement of the slider 52 inside the groove 51 drives the plug rod 53 to move. The movement of the plug rod 53 causes it to move out of the inside of the jack 54. The separation of the plug rod 53 and the jack 54 causes the mounting plate 8 to lose its limit inside the mounting groove 7. At this time, the screen 9 can be moved. The movement of the screen 9 drives the mounting plate 8 to move out of the inside of the mounting groove 7, thus completing the disassembly operation of the screen 9. Through the cooperation of the above structures, the screen 9 can be disassembled, and then it is convenient to replace the screens 9 with different aperture sizes, so as to meet different screening production requirements.

[0030] Specifically, a vertical rod 55 is fixedly installed on the top surface of the U-shaped frame 1. A sliding ring 56 is slidably connected to the surface of the vertical rod 55. An articulated plate 57 is hinged to the circumferential side wall of the sliding ring 56. One end of the articulated plate 57 away from the sliding ring 56 is hinged to the slider 52.

[0031] In this embodiment: The setting of the articulated plate 57 plays a role in driving the slider 52 to move inside the groove 51.

[0032] Specifically, a limiting plate 58 is fixedly installed on the surface of the end of the vertical rod 55 away from the U-shaped frame 1. A spring 59 is fixedly installed between the limiting plate 58 and the sliding ring 56.

[0033] In this embodiment: The setting of the spring 59 plays a role in restricting the position of the sliding ring 56 on the surface of the vertical rod 55.

[0034] Working principle: By setting the knocking device 4, when it is necessary to screen the slurry, first pour the slurry into the inner part of the feeding hopper 3, then the slurry falls from the inner part of the feeding hopper 3 onto the surface of the screen 9, and then after being screened by the screen 9, it falls into the temporary storage tank 6. Then, when the screen 9 is blocked during the screening process, turn on the electric telescopic rod 46. The electric telescopic rod 46 starts to drive the moving plate 44 to move inside the sliding groove 43. The movement of the moving plate 44 inside the sliding groove 43 drives the connecting plate 47 to move. The movement of the connecting plate 47 drives the rack 48 to move. The movement of the rack 48 meshes with the gear 49, thereby causing the gear 49 to rotate. The rotation of the gear 49 drives the rotating rod 41 to rotate. The rotation of the rotating rod 41 drives the knocking rod 42 to rotate, and then the knocking rod 42 continuously beats the screen 9, causing the screen 9 to vibrate, preventing the screen 9 from being blocked. Through the cooperation of the above structures, the knocking rod 42 can beat the screen 9, causing the screen 9 to vibrate, and thus enabling the normal use of the screen 9 and ensuring that the screening efficiency is not affected. When it is necessary to replace the screen 9, slide the slip ring 56, so that the slip ring 56 moves on the surface of the vertical rod 55. The movement of the slip ring 56 on the surface of the vertical rod 55 will squeeze the spring 59, causing the spring 59 to be compressed under force. At the same time, the movement of the slip ring 56 on the surface of the vertical rod 55 also drives the articulated plate 57 to move. The movement of the articulated plate 57 pulls the slider 52 to move inside the groove 51. The movement of the slider 52 inside the groove 51 drives the insertion rod 53 to move. The movement of the insertion rod 53 causes it to move out of the inside of the insertion hole 54. The separation of the insertion rod 53 and the insertion hole 54 causes the mounting plate 8 to lose its limit inside the mounting groove 7. At this time, the screen 9 can be moved. The movement of the screen 9 drives the mounting plate 8 to move out of the inside of the mounting groove 7, thus completing the disassembly operation of the screen 9. Through the cooperation of the above structures, the screen 9 can be disassembled, and thus it is convenient to replace the screen 9 with different aperture sizes to meet different production screening requirements.
