Description

Technical Field

[0001] This utility model relates to the field of screen plate technology, specifically a screen plate for a hydraulic pulper. Background Technology

[0002] Hydraulic pulpers are key equipment in the pulp and paper industry. They are mainly composed of rotors, tanks, transmission mechanisms, slag discharge devices, screen plates, and other structures. They are commonly used to shred waste paper, pulp boards, and damaged paper. As an important component of the hydraulic pulper, the screen plate's core function is to separate fibers and impurities in the pulp through its precise porous structure. This prevents impurities from entering subsequent processing stages, which helps stabilize the operation of subsequent bleaching, beating, and other processes, ultimately improving the strength and whiteness of the finished paper.

[0003] When using existing hydraulic pulping machine screens, most of them are one-piece designs, making it difficult for operators to individually replace damaged or malfunctioning parts based on their actual condition. In order to avoid prolonged downtime of the hydraulic pulping machine, in most cases, the damaged screens can only be completely removed and replaced with new ones, which to some extent wastes resources and is not conducive to the normal use of hydraulic pulping machine screens.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-7As shown, a screen plate for a hydraulic pulper includes an upper cover 1, a lower cover 2 adapted to the bottom of the upper cover 1, and a screen plate assembly 4 for separating impurities from the slurry inside the lower cover 2. By setting the screen plate assembly 4, the commonly used integrated screen plate is disassembled into multiple independent parts. When one or more independent components are damaged and cannot be used, the workers can replace the damaged or failed parts individually according to the actual damage, thereby avoiding waste of resources and improving the applicability and flexibility of the screen plate; an annular groove 3 is provided with... Inside the lower cover 2, the annular groove 3 has an annular seat 7 inside, and the top of the annular seat 7 is connected to the upper cover 1. Multiple receiving cavities 8 are symmetrically arranged inside the annular seat 7. The receiving cavity 8 has a locking component 9 inside to facilitate the assembly and disassembly of the upper cover 1. By setting the locking component 9, the upper cover 1 and the lower cover 2 can be easily assembled. When the staff needs to inspect and maintain the screen plate assembly 4, the locking component 9 can be used to disconnect the upper cover 1 and the lower cover 2, thereby facilitating the inspection and maintenance of the screen plate assembly 4.

[0019] The engaging assembly 9 includes a ball screw 91 disposed inside the receiving cavity 8. The ball screw 91 is rotatably connected to both ends of the inner wall of the receiving cavity 8 via bearings. A nut block 92 is helically connected to the outer side of the ball screw 91. The nut block 92 is located below the upper cover 1. A U-shaped frame 93 is fixedly connected to the outer side of the nut block 92. A locking rod 94 is provided at the bottom of both sides of the receiving cavity 8. A locking groove 97 corresponding to the locking rod 94 is opened on the inner wall of the annular groove 3. One end of the locking rod 94 extends into the locking groove 97. Both ends of the U-shaped frame 93 are provided with wedge-shaped portions 95. A wedge-shaped groove 96 corresponding to the wedge-shaped portion 95 is opened on the top of the locking rod 94. The bottom surface of the wedge-shaped portion 95 contacts the wedge-shaped groove 96. Figure 3 , Figure 6 and Figure 7 As shown, when the staff needs to assemble the upper cover 1 and the lower cover 2, the ball screw 91 can be used to drive the screw nut 92 to slide down along its axis. Then the screw nut 92 drives the wedge-shaped parts 95 at both ends of the U-shaped frame 93 into the wedge-shaped groove 96 at the top of the clamping rod 94. As the wedge-shaped parts 95 continue to go deeper, the two clamping rods 94 will move away from each other until one end is inserted into the groove 97. At this time, under the restriction of the clamping rods 94 and the groove 97, the annular seat 7 cannot be separated from the annular groove 3, thereby realizing the convenient assembly between the upper cover 1 and the lower cover 2.

[0020] Both sides of the U-shaped frame 93 are fixedly connected to a first slider 10. A first groove 11 corresponding to the first slider 10 is formed on the inner wall of the receiving cavity 8. The first slider 10 is located inside the first groove 11. A second slider 12 is fixedly connected to the bottom of the locking rod 94. A second groove 13 corresponding to the second slider 12 is formed on the bottom surface of the receiving cavity 8. The second slider 12 is located inside the second groove 13. A relief groove 14 is formed on the side of the two locking rods 94 that is close to each other. A spring 15 is fixedly connected inside the relief groove 14. One end of the spring 15 is connected to the inner wall of the receiving cavity 8. Figure 3 , Figure 6 and Figure 7 As shown, when the staff needs to inspect and maintain the screen plate assembly 4, the ball screw 91 can be used to drive the screw nut 92 to slide upward along its axis. Then the screw nut 92 will drive the wedge 95 away from the wedge groove 96. As the wedge 95 moves further away, the two locking rods 94 will move closer to each other under the action of the spring 15 until one end is completely disengaged from the inside of the locking groove 97. At this time, the upper cover 1 can be removed from the lower cover 2, which facilitates the inspection and maintenance of the screen plate assembly 4. In addition, by setting the first slider 10, the first sliding groove 11, the second slider 12 and the second sliding groove 13, the locking rods 94 and the U-shaped frame 93 can be kept smooth during the sliding process, which helps to improve the working stability of the locking assembly 9.

[0021] The top of the upper cover 1 has a countersunk hole 16 corresponding to the ball screw 91. The top end of the ball screw 91 passes through the countersunk hole 16 and is fixedly connected to a rotating block 17. The top of the rotating block 17 has an internal hexagonal groove 18 for engaging with an internal hexagonal wrench. Figure 7 As shown, in actual use, the countersunk hole 16 can prevent the rotating block 17 from protruding and affecting the normal operation of the rotor and other components above the screen plate assembly 4, while the internal hexagonal groove 18, together with tools such as an internal hexagonal wrench, can facilitate the adjustment of the locking assembly 9.

[0022] The sieve plate assembly 4 includes multiple partition plates 41 disposed inside the lower cover 2. Each partition plate 41 is connected to both sides of the inner wall of the lower cover 2, dividing the internal space of the lower cover 2 into multiple placement slots 44. Each placement slot 44 contains a fan-shaped plate 42 located between the upper cover 1 and the lower cover 2. The fan-shaped plate 42 has intermittently spaced filter holes 43 inside. Figure 1 , Figure 2 and Figure 3 As shown, by disassembling the existing common integrated screen plate into multiple independent sector plates 42, when one or more sector plates 42 are damaged and cannot be used, it is convenient for staff to replace the damaged or failed parts individually according to the actual damage situation. This can avoid the waste of resources and improve the applicability and flexibility of the screen plate.

[0023] The top of the upper cover 1 and the bottom of the lower cover 2 are both provided with through slots 6 corresponding to the fan-shaped plate 42. An arc-shaped plate 5 is provided on one side of the inner wall of the placement slot 44, and the top of the arc-shaped plate 5 is connected to the upper cover 1. Figure 2 , Figure 3 and Figure 4 As shown, by setting the through groove 6, the slurry can easily enter the filter hole 43 of the fan-shaped plate 42 for impurity separation. The arc plate 5 facilitates the initial engagement between the upper cover 1 and the lower cover 2, and also facilitates the docking of the locking rod 94 and the locking groove 97. Specifically, when each arc plate 5 enters the inner wall of the placement groove 44, the locking rod 94 and the locking groove 97 are aligned, which further facilitates the convenient assembly between the upper cover 1 and the lower cover 2.

[0024] Working principle: First, the existing integrated screen plate is disassembled into multiple independent sector plates 42 by the screen plate assembly 4. When one or more sector plates 42 are damaged and cannot be used, it is convenient for the staff to replace the damaged and failed parts individually according to the actual damage situation. This can avoid the waste of resources and improve the applicability and flexibility of the screen plate. When the staff needs to inspect and maintain the screen plate assembly 4, the connection between the upper cover 1 and the lower cover 2 can be released by the locking assembly 9. This makes it convenient for the staff to take the screen plate assembly 4 out from the lower cover 2, which facilitates the inspection and maintenance of the screen plate assembly 4.
