[0018] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0019] Refer to Figure 1 、 Figure 2 The present utility model provides an inclined sieve for papermaking pulp washing, which mainly includes a box body 1. A feed inlet 2 is arranged at the top of the box body 1 for receiving the pulp to be screened; a discharge outlet 3 is arranged at the lower part of the box body 1. A sieve plate 5 is arranged inside the box body 1. The sieve plate 5 is made of corrosion-resistant and wear-resistant materials, and a sieve surface composed of a number of wedge-shaped bars is arranged thereon; the sieve plate 5 extends from the feed inlet 2 to the discharge outlet 3; a clamping mechanism 6 is arranged on one inner wall of the box body 1 for fixing one end of the sieve plate 5, and an inclined hole 101 and a fixing mechanism are arranged on the other side, which is opposite to the clamping mechanism 6. The inclined hole 101 is adapted to the sieve plate 5. The sieve plate 5 is inserted into the box body 1 through the inclined hole 101 and fixed by the fixing mechanism; a vibration motor 4 is arranged on the box body 1. Through the vibration of the vibration motor 4, it can help the pulp to pass through the sieve plate 5 for screening and washing better.

[0020] Refer to Figure 3 The clamping mechanism 6 includes a positioning groove 601 and a clamping plate 607. Driving guide holes 603 and two clamping guide holes 602 are arranged at both ends of the positioning groove 601; the driving guide holes 603 are arranged along the depth direction of the positioning groove 601, and the two clamping guide holes 602 are perpendicularly arranged on both sides of the driving guide holes 603; a push plate 605 is arranged in the positioning groove 601. Both ends of the push plate 605 are arranged in the driving guide holes 603. Clamping sliders 604 are slidably arranged in the clamping guide holes 602. A connecting rod 606 is arranged between the clamping sliders 604 and the push plate 605. Both ends of the connecting rod 606 are rotatably connected to the clamping sliders 604 and the push plate 605 respectively. The clamping plate 607 is fixedly connected to the clamping slider 604; when the sieve plate 5 is inserted into the positioning groove 601 and the push plate 605 is pushed to move towards its bottom, the connecting rod 606 drives the two clamping sliders 604 to approach each other, so as to fix one end of the sieve plate 5 through the clamping plate 607. Refer to Figure 2 A number of positioning plates 608 are arranged in the positioning groove 601. Driving guide holes 603 and two clamping guide holes 602 are arranged on the positioning plates 608. A clamping groove 501 matching the positioning plate 608 is arranged at one end of the sieve plate 5 away from the converging plate 7, so that the sieve plate 5 can be accurately inserted into the positioning groove 601, and at the same time, the vibration during the operation of the equipment is prevented from causing the displacement of the sieve plate 5.

[0021] Reference Figure 4 、 Figure 5 The fixing mechanism includes a plurality of sliding seats 102 arranged on the inner wall of the box body 1. The sliding seats 102 are symmetrically arranged on both sides of the inclined hole 101. A strip-shaped sliding hole 103 and a fixing strip 105 are arranged on the sliding seat 102. A converging rod 104 is arranged in the strip-shaped sliding hole 103. The fixing strip 105 can slide on the sliding seat 102 and is connected to the converging rod 104. Converging holes 106 are arranged on the box body 1 on both sides of the inclined hole 101. Reference Figure 2 On one side of the sieve plate 5, a converging plate 7 is arranged. A plurality of wedge blocks 701 are arranged on the converging plate 7. The wedge blocks 701 are arranged in a mirror image with the sieve plate 5 as the center and are matched with the converging holes 106. A clamping groove 702 matched with the converging rod 104 is arranged at the lower end of the wedge block 701. A pull ring 8 is arranged on the outer side of the converging plate 7, which is convenient for pulling the converging plate 7 when needed, so that the wedge block 701 is separated from the converging hole 106, thus facilitating the disassembly of the sieve plate 5.

[0022] During the process of inserting the sieve plate 5 into the box body 1 through the inclined hole 101, the inclined surface of the wedge block 701 contacts the converging rod 104, pushing the two converging rods 104 closer to each other, and further making the fixing strip 105 closely adhere to the sieve plate 5. When the sieve plate 5 is completely inserted, the converging rod 104 enters the clamping groove 702, firmly fixing the sieve plate 5 in the box body 1.

[0023] In order to enhance the sealing performance, elastic sealing materials, such as rubber sealing strips, are arranged on the adjacent ends of the two clamping plates 607 and the two fixing strips 105, and telescopic waterproof materials connected to the inner wall of the box body 1 are arranged on the other side to enhance the sealing performance between the sieve plate 5 and the box body 1 and prevent the pulp from leaking.
