Description

Technical Field

[0001] This utility model relates to the field of screen plate technology, specifically a quick-release screen plate for a paper pulping machine. Background Technology

[0002] In the papermaking industry, hydraulic pulpers are mainly used to shred various types of paperboard, damaged paper, and waste paper. The screen plate is an important component of the hydraulic pulper, and the screen aperture is a significant factor affecting the production capacity of the hydraulic pulper.

[0003] According to a public notice (Announcement No.: CN203569374U) of a sieve plate for a hydraulic pulper, the inner and outer edges of the sieve plate body are provided with mounting holes, and a number of circular sieve holes are provided on the sieve plate body near the inner edge. The sieve plate body is provided with elongated sieve slots, which are evenly distributed on the sieve plate body in a spiral pattern. The sieve plate is then installed on the mounting base using bolts.

[0004] However, in actual use, after prolonged use, the screen plates of the aforementioned equipment are easily clogged by impurities such as resin, metal shavings, or sand particles in the pulp. This necessitates frequent disassembly and cleaning of the screen plates. Since the screen plates are fixed with bolts, disassembly takes a significant amount of time, thus affecting the working efficiency of the equipment. In view of this, we propose a quick-release screen plate for paper pulping machines. Utility Model Content

[0005] The purpose of this invention is to provide a quick-release screen plate for a paper pulping machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick-release screen plate for a paper pulper, comprising a mounting base, an mounting groove on the upper surface of the mounting base, a flow groove at the bottom of the inner wall of the mounting groove, a support rod fixedly connected to the inner wall of the flow groove, a discharge port at the bottom of the flow groove, a screen plate disposed inside the mounting groove, and a limiting component disposed on the outer surface of the mounting base, the limiting component comprising:

[0007] A fastener is fixedly connected to the outer surface of the mounting base. A slide rail is provided on the side of the fastener, and a slider is slidably connected inside the slide rail.

[0008] A placement groove is provided at the bottom of the slider near the end. A pressing block is provided inside the placement groove, and a rotating component is rotatably connected to the upper surface of the pressing block.

[0009] An embedding rod is fixedly connected to the bottom of the sieve plate near the center, and an embedding hole is provided at the bottom of the inner wall of the mounting groove.

[0010] Preferably, the embedding rods are arranged in a linear array and evenly distributed at the bottom of the sieve plate near the center. The positions of the embedding rods correspond to the positions of the embedding holes, which allows the embedding rods to be well inserted into the embedding holes.

[0011] Preferably, the rotating component is composed of a rotating block fixedly connected to the end of a threaded rod, the end of the rotating component is configured to pass through the slider, and the outer surface of the rotating component is threadedly connected to the slider, which allows the pressing block to move when the rotating component rotates.

[0012] Preferably, the center of the fixing member corresponds to the center of the slide rail, and the fixing members are evenly distributed in a circumferential array on the outer surface of the mounting base, which allows the screen plate to be more stably positioned.

[0013] Preferably, an auxiliary component is provided at the bottom of the inner wall of the mounting groove near the corner. The auxiliary component includes a slot, which is opened at the bottom of the inner wall of the mounting groove near the corner. A clip is fixedly connected to the bottom of the sieve plate.

[0014] Preferably, the card is semi-cylindrical, and the position of the card corresponds to the position of the card slot.

[0015] Preferably, the size of the card slot is adapted to the size of the card.

[0016] Compared with the prior art, this utility model provides a quick-release screen plate for a paper pulping machine, which has the following advantages:

[0017] 1. This paper pulper uses a quick-release screen plate. To enable quick disassembly of the screen plate, place it inside the mounting groove and align the insert rod with the insert hole. After the screen plate is fully placed inside the mounting groove, the insert rod will engage with the insert hole. Then, move the slider so that the position of the pressing block corresponds to the upper surface of the screen plate near the corner. Rotate the rotating part to move the pressing block downward inside the mounting groove, so that the bottom of the pressing block contacts the upper surface of the screen plate. This allows the pressing block to exert pressure on the screen plate and also limits the slider, thus allowing the screen plate to be quickly positioned and disassembled.

[0018] 2. This paper pulper uses a quick-release screen plate. In order to make the screen plate more stable, when the embedding rod is inserted into the embedding hole, the position of the semi-cylindrical clip set near the corner of the bottom of the screen plate will correspond to the position of the slot. This way, after the screen plate is installed in the mounting slot, the clip will be inserted into the slot, so that the screen plate can be stably limited in the mounting seat.

Detailed Implementation

[0025] like Figures 1-5 As shown, this utility model provides a technical solution: a quick-release screen plate for a paper pulping machine, including a mounting base 1, an mounting groove 2 on the upper surface of the mounting base 1, a flow groove 3 at the bottom of the inner wall of the mounting groove 2, a support rod 5 fixedly connected to the inner wall of the flow groove 3, a discharge port 4 at the bottom of the flow groove 3, a screen plate 6 inside the mounting groove 2, and a limiting component 7 on the outer surface of the mounting base 1. The limiting component 7 includes a fixing part 703, a slide rail 704, a slider 705, a placement groove 706, a pressing block 707, a rotating part 708, an embedding rod 702, and an embedding hole 701.

[0026] In this embodiment of the utility model, the fixing member 703 is fixedly connected to the outer surface of the mounting base 1, and the center of the fixing member 703 corresponds to the center of the slide rail 704. The fixing members 703 are evenly distributed in a circumferential array on the outer surface of the mounting base 1, which allows the sieve plate 6 to be more stably positioned. The fixing member 703 has a slide rail 704 on its side, and a slider 705 is slidably connected inside the slide rail 704. A placement groove 706 is opened at the bottom of the slider 705 near the end. A pressing block 707 is provided inside the placement groove 706, and a rotating member 708 is rotatably connected to the upper surface of the pressing block 707. 8 is composed of a rotating block fixedly connected to the end of a threaded rod. The end of the rotating part 708 is set through the slider 705, and the outer surface of the rotating part 708 is threadedly connected to the slider 705. This allows the pressing block 707 to move when the rotating part 708 rotates. The embedded rod 702 is fixedly connected to the bottom of the screen plate 6 near the center. The embedded rods 702 are evenly distributed in a linear array near the bottom of the screen plate 6. The position of the embedded rod 702 corresponds to the position of the embedded hole 701, which allows the embedded rod 702 to be well inserted into the embedded hole 701. The bottom of the inner wall of the mounting groove 2 is provided with an embedded hole 701.

[0027] Meanwhile, an auxiliary component 8 is provided at the bottom of the inner wall of the mounting groove 2 near the corner. The auxiliary component 8 includes a slot 802, which is located at the bottom of the inner wall of the mounting groove 2 near the corner. The size of the slot 802 is adapted to the size of the clip 801. The bottom of the screen plate 6 is fixedly connected to the clip 801, which is semi-cylindrical. The position of the clip 801 corresponds to the position of the slot 802. This way, when the embedded rod 702 is inserted into the embedded hole 701, the position of the semi-cylindrical clip 801 at the bottom of the screen plate 6 near the corner will correspond to the position of the slot 802. This way, after the screen plate 6 is installed in the mounting groove 2, the clip 801 will be inserted into the slot 802, so that the screen plate 6 can be stably limited inside the mounting base 1.

[0028] In this invention, during use, the sieve plate 6 is placed inside the mounting groove 2, and the embedding rod 702 is aligned with the embedding hole 701. After the sieve plate 6 is completely placed inside the mounting groove 2, the embedding rod 702 will be engaged inside the embedding hole 701. Then, the slider 705 is moved so that the position of the pressing block 707 corresponds to the upper surface of the sieve plate 6 near the corner. The rotating component 708 is rotated to move the pressing block 707 downward inside the placement groove 706, so that the bottom of the pressing block 707 contacts the upper surface of the sieve plate 6. This allows the pressing block 707 to exert pressure on the sieve plate 6 and also limits the slider 705, so that the sieve plate 6 can be quickly limited and can be quickly disassembled.

[0029] Furthermore, as the embedding rod 702 is inserted into the embedding hole 701, the position of the semi-cylindrical clip 801 located near the corner of the bottom of the sieve plate 6 corresponds to the position of the slot 802. This allows the clip 801 to fit perfectly into the slot 802 after the sieve plate 6 is installed in the mounting groove 2, thus ensuring that the sieve plate 6 is stably positioned within the mounting base 1.

[0030] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
