Straight skirt edges are arranged on both sides of a conveying belt of an inclined conveyor, and a plurality of vertically-extended baffles are equidistantly arranged on the surfaces of the straight skirt edges, and each baffle and the straight skirt edge form a storage cavity. The raw materials can be pre-hydrated and expanded in the storage cavity during the movement of the inclined conveyor on the slope, so that the expansion time in a pulper is shortened, and the disintegration efficiency of the pulper body is improved. In addition, the end part of the rack of the inclined conveyor is fixedly connected with a folding belt support through a tension spring. The folding belt support can force the straight skirt edges and the baffles to be folded, so that the pre-hydrated raw materials can be accurately poured into the pulper. Through the above structural design, the production efficiency of the pulper body can be improved by adding a pre-hydrating treatment structure.

Description

Technical Field

[0001] This application relates to the field of papermaking equipment technology, and more specifically, to a pulper for clean papermaking. Background Technology

[0002] A pulper is a device used to process raw materials such as waste paper, pulp board, and damaged paper. Its main function is to break these raw materials into fibers and make fiber suspension pulp by adding water.

[0003] In related technologies, the working principle of a pulper is mainly achieved through a combination of mechanical action and fluid friction. Specifically, raw materials such as waste paper, pulp board, and damaged paper are fed into the pulping tank to absorb water and swell. Subsequently, the rotating impeller at the bottom and the auger in the middle tear and grind the wet paper sheet, thereby further breaking the wet paper sheet into individual fibers to form a fiber suspension pulp.

[0004] However, in the actual pulping process, raw materials such as waste paper, pulp board, and damaged paper need to be soaked in the pulping tank for 5-10 minutes before they can be fully swelled. This will undoubtedly prolong the pulping cycle for the above-mentioned raw materials, resulting in a low pulping efficiency of the pulper. Summary of the Invention

[0005] In view of this, embodiments of this application provide a clean pulper for papermaking to solve the problem of low raw material breaking efficiency in related technologies.

[0006] To achieve the above objectives, the embodiments of this application provide the following technical solutions:

[0007] A clean pulper for papermaking, comprising:

[0008] The pulper body includes a vertically arranged pulping tank;

[0009] An inclined conveyor includes a frame and a conveyor belt wound around the frame. The discharge end of the conveyor belt is located above the pulping tank. Both sides of the conveyor belt are provided with straight skirts. Several baffles are evenly distributed on its surface. Each baffle and the straight skirts enclose a storage cavity. The baffles, the straight skirts and the conveyor belt are made of the same material.

[0010] A folding strip support is provided at the end of the frame near the discharge end via a tension spring; wherein,

[0011] After the raw materials and water are pre-wetted in the storage chamber, when the conveyor belt runs to the discharge end, the straight edge skirt contacts the baffle and bends the belt folding bracket to pour the pre-wetted raw materials and water into the pulping tank.

[0012] In some possible implementations, the top of the straight skirt is flexibly connected with a bend that bends to both sides along the crease when it contacts the folded strap support.

[0013] In some possible implementations, the bend extends obliquely upward and outward from the conveyor belt, and the top shape of each baffle is adapted to the contour of the bend.

[0014] In some possible implementations, a spring seat is fixedly provided at the end of the frame near the discharge end, and the two ends of the tension spring are respectively connected to the spring seat and the folding belt bracket.

[0015] In some possible implementations, the contact surfaces between the folded strap bracket and the straight edge skirt and the baffle are chamfered surfaces.

[0016] In some possible implementations, the conveyor belt, the straight-edged skirt, and the baffle are all made of corrosion-resistant rubber.

[0017] The clean paper pulper provided in this application has at least the following beneficial effects:

[0018] In the clean paper pulper provided in this application embodiment, straight-edged skirts are provided on both sides of the conveyor belt of the inclined conveyor, and multiple vertically extending baffles are evenly distributed on their surfaces. Each baffle and the straight-edged skirts together form a storage cavity. During the upward movement of the inclined conveyor on the incline, the raw material can be pre-wetted and swelled through the storage cavity, thereby shortening the swelling time in the pulping tank and improving the pulping efficiency of the pulper body. Furthermore, a folding belt bracket is fixedly connected to the end of the frame of the inclined conveyor via a tension spring. The folding belt bracket can force the straight-edged skirts and baffles to bend, thereby achieving accurate pouring of pre-wetted raw material into the pulping tank. By adopting the above structural design, the production efficiency of the pulper body can be improved by adding a pre-wetting treatment structure. Attached Figure Description

[0032] 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.

[0033] like Figure 1 and Figure 5 As shown in the illustration, the clean papermaking pulper provided in this application includes a pulper body 100, an inclined conveyor 200, and a folding support 500. The pulper body 100 is a device for pulping raw materials such as waste paper, pulp board, and waste paper. The pulper body 100 includes a vertically arranged pulping tank 110 with its opening facing upwards. Waste paper, pulp board, and waste paper to be pulped can be poured into the pulping tank 110 through the opening. The working process and principle of the pulper body 100 are well known to those skilled in the art, and will not be described in detail here.

[0034] The inclined conveyor 200 is a device capable of conveying materials within an inclination angle range of 0° to 90°, and is particularly suitable for material conveying on slopes or in situations with significant height changes. In this embodiment, the inclined conveyor 200 is positioned beside the pulping tank 110, with its top discharge port located above the pulping tank 110. The inclined conveyor 200 includes a frame 210 and a conveyor belt 220 wound around the frame 210. The conveyor belt 220 transports the raw material from the bottom to the top and into the pulping tank 110.

[0035] like Figure 3 As shown, straight edge skirts 300 are provided on both sides of the conveyor belt 220, and the straight edge skirts 300 extend along the length of the conveyor belt 220. Furthermore, baffles 400 are vertically provided on the surface of the conveyor belt 220, forming a storage cavity between the baffles 400 and the straight edge skirts 300 on both sides. The conveyor belt 220, straight edge skirts 300, and baffles 400 can all be made of the same material, such as corrosion-resistant rubber, and the three can also be integrally molded through a vulcanization process.

[0036] In this embodiment, the storage chamber can be used to store raw materials such as waste paper, pulp board, and damaged paper. It can also hold water. In actual use, the raw materials can be fed into the storage chamber of the inclined conveyor 200, and water can be poured into the chamber through a water pipe to achieve pre-wetting treatment of the raw materials.

[0037] Continue as Figure 2 and Figure 5 As shown, a belt folding bracket 500 is provided at the end of the frame 210 of the inclined conveyor 200, located near the end of the frame 210 close to the pulping tank 110. The belt folding bracket 500 is fixedly connected to the end of the frame 210 by a tension spring 600, and the distance between the belt folding bracket 500 and the end face of the frame 210 is less than the extension length of the straight edge skirt 300 and the baffle 400 of the conveyor belt 220. Preferably, a spring seat 211 is fixedly provided at the end of the frame 210 near the discharge end, and the two ends of the tension spring 600 are respectively connected to the spring seat 211 and the belt folding bracket 500. Therefore, the straight edge skirt 300 and the baffle 400 will bend when they come into contact with the belt folding bracket 500.

[0038] The following is combined Figures 1-5 The working principle and working process of the clean paper pulper provided in the embodiments of this application are described.

[0039] Waste paper, pulp, and scrap paper are placed in the storage chamber, and water is injected into the chamber through a water pipe. The conveyor belt of the inclined conveyor 200 undergoes a pre-wetting and swelling process during its ascent up the incline, thereby increasing the moisture content of the raw materials. When the conveyor belt 220 reaches the discharge end, the belt folding bracket 500 squeezes the straight edge skirt 300 and baffle 400 of the conveyor belt 220, forcing them to bend, thus achieving the automatic tilting and dumping function of the storage chamber. The pre-wetted raw materials can be more quickly broken down by the pulper body 100, thereby improving the pulping efficiency of the pulper body 100.

[0040] In the clean paper pulper provided in this embodiment, straight-edged skirts 300 are provided on both sides of the conveyor belt 220 of the inclined conveyor 200, and multiple vertically extending baffles 400 are evenly distributed on their surfaces. Each baffle 400 and the straight-edged skirts 300 together form a storage cavity. During the upward movement of the inclined conveyor 200 on the incline, the raw material can be pre-wetted and swelled through the storage cavity, thereby shortening the swelling time in the pulping tank 110 and improving the pulping efficiency of the pulper body 100. Furthermore, a folding belt bracket 500 is fixedly connected to the end of the frame 210 of the inclined conveyor 200 via a tension spring 600. The folding belt bracket 500 can force the straight-edged skirts 300 and the baffles 400 to bend, thereby achieving precise pouring of the pre-wetted raw material into the pulping tank 110. Using the above structural design, the production efficiency of the pulper body 100 can be improved by adding a pre-wetting treatment structure.

[0041] In some embodiments, such as Figure 4 As shown, the top of the straight skirt 300 is flexibly connected to a bent portion 310, which bends along the crease 320 to both sides when it contacts the belt folding bracket 500. Preferably, the bent portion 310 extends obliquely upward and outward of the conveyor belt 220, and the top shape of each baffle 400 is adapted to the contour of the bent portion 310.

[0042] In the above structural design, the bending portion 310 can achieve directional bending through the pre-made creases 320, ensuring that the straight edge skirt 300 and the baffle 400 can be flipped in time to avoid deformation caused by local stress concentration. The flexible connection structure allows the bending portion 310 to quickly return to its original position after bending, thereby reducing structural fatigue damage. In addition, the bending portion 310, with its two-sided unfolding design, can form a preset bending angle, thus facilitating timely bending after contact with the folding strap bracket 500.

[0043] In some embodiments, such as Figure 5As shown, the contact surfaces of the folding strap bracket 500 with the straight edge skirt 300 and the baffle 400 are chamfered surfaces 510. By designing the contact surfaces of the folding strap bracket 500 as chamfered surfaces 510, the frictional resistance when it contacts the straight edge skirt 300 and the baffle 400 can be reduced, thereby reducing wear between them. Furthermore, the chamfered surface 510 design can also eliminate right-angle impacts, thereby reducing noise generated during bending.
