[0023] refer to Figs. 1-3 As shown, one embodiment of this utility model is as follows:

[0024] A sieve plate for a hydraulic pulper includes a sieve plate frame 1. The inner and outer edges of the sieve plate frame 1 are provided with mounting holes 2. Multiple fan-shaped holes 3 are evenly distributed on the sieve plate frame 1 between the inner and outer edges. A connecting arm 4 is provided between adjacent fan-shaped holes 3. The bottom wall of the sieve plate frame 1 is provided with a fixing plate 5 that spans the fan-shaped holes 3. A fixing screw hole 6 is opened in the center of the fixing plate. A sub-sieve plate 7 is inserted into the fan-shaped holes 3. The sub-sieve plate 7 is provided with countersunk screw holes 8 that are adapted to the fixing screw holes 6. A number of sieve holes 9 are opened on the sub-sieve plate 7.

[0025] Specifically, the sub-sieve plate 7 and the sieve plate frame 1 are fixed to the countersunk screw hole 8 and the fixing 6 by countersunk screws. The inner wall of the sieve hole 9 is provided with a spiral ridge to improve the separation effect of the slurry.

[0026] With its modular design, only the damaged sub-screen plate needs to be replaced when partial damage occurs, eliminating the need for complete replacement and greatly reducing maintenance costs. During replacement and maintenance, only one countersunk screw needs to be removed, resulting in higher maintenance efficiency.

[0027] Furthermore, the sub-sieve plate 7 is provided with lifting clips 10 on both sides of the countersunk screw hole 8, and the line connecting the lifting clips 10 and the countersunk screw hole 8 is located directly above the fixing plate 5.

[0028] The two sides of the sub-sieve plate 7 located at the two sides of the countersunk hole 5 are provided with grooves 11, and the pulling clamping pieces 10 are arranged in the grooves 11.

[0029] The pulling clamping pieces 10 are convenient to cooperate with the external clamping hook pieces, and the sub-sieve plate 7 is convenient to pull up or put down.

[0030] In the embodiment, the fan-shaped hole 3 comprises a bearing hole 301 and a positioning hole 302 arranged in sequence from top to bottom, and the sub-sieve plate 7 comprises a trapezoidal plate 701 and a positioning plate 702 arranged in sequence from top to bottom, the trapezoidal plate 701 is matched with the bearing hole 301, and the positioning plate 702 is matched with the positioning hole 302.

[0031] The hole diameter of the bearing hole 301 gradually decreases from top to bottom, and the lower end hole diameter of the bearing hole 301 is consistent with the hole diameter of the positioning hole 302.

[0032] The fan-shaped hole 3 is two-section type, and the upper part is the bearing hole 301 with a gradually reduced hole diameter, so as to bear the weight of the sub-sieve plate 7, and the gravity of the sub-sieve plate 7 is uniformly distributed downwards, thereby avoiding the bearing of the fixed plate 5, and the fixed plate 5 only plays a fixing role, and the stability is greatly improved.

[0033] Further, the trapezoidal plate 701 and the positioning plate 702 are integrally formed, the thickness of the trapezoidal plate 701 is consistent with the depth of the bearing hole 301, and the thickness of the positioning plate 702 is less than the depth of the positioning hole 302.

[0034] The thickness of the trapezoidal plate 701 is consistent with the depth of the bearing hole 301, and after installation and cooperation, the upper end surfaces are kept on the same horizontal plane.

[0035] Since the fixed plate 5 adopts a long strip structure, the thickness of the positioning plate 702 is less than the depth of the positioning hole 302, and the size difference is 0.5-1.5 cm in specific implementation. The thickness of the positioning plate 702 is slightly less than the depth of the positioning hole 302, so that after installation and fixation, the fixed plate 5 is in an arc shape, the sub-sieve plate 7 is more closely attached to the fan-shaped hole, and the stability is better. Therefore, the fixed screw hole 6 is arranged at the center of the fixed plate 5.

[0036] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part of the technical features, and any modification, equivalent replacement, improvement and the like made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
