Description

Technical Field

[0001] This utility model relates to the field of pulping machine technology, specifically to a water receiving device for the wet end support roller of a pulping machine. Background Technology

[0002] A pulp board machine for papermaking is used to process pulp to a certain thickness and density. Its function is to process the pulp through a series of processes, including mixing, tumbling, and compression, to produce a complete sheet of paper. The wet end forming section of the pulp board machine consists of the upper and lower wires. After installation, the upper and lower support rollers tension the wires to achieve the required tension. During operation, the upper wire carries a large amount of white water and washing water, which falls onto the frame beams below the support rollers. Fibers in the white water accumulate on the beams, forming slurry. Once the slurry accumulates to a certain extent, it falls onto the forming wire. The forming wire carries this slurry into the pressing zone, where it adheres to the surface of the lowered sheet, affecting product quality. It can even stick to the paper web in the processing section, causing paper web interruptions and limiting the pulp board machine's capacity. Utility Model Content

[0003] This invention addresses the problem of slurry dripping onto the forming screen during the operation of a pulping machine, leading to uncontrolled product quality, instability in continuous and stable operation, and increased costs. It provides a water-collecting device for the wet-end support roller of the pulping machine, which collects and discharges the slurry that falls onto the screen during operation, thus preventing disruption to the pulping machine's operation, uncontrolled product quality, and increased costs.

[0004] The technical solution adopted in this utility model is:

[0005] A fixed block is located inside the pulping machine and directly below the support roller. A liquid receiving groove is provided on the end face of the fixed block facing the support roller. A drain outlet communicating with the liquid receiving groove is provided on the bottom of the fixed block. A water outlet pipe is connected at one end to the drain outlet of the fixed block and at the other end to discharge the slurry collected in the liquid receiving groove. Two fixing plates are respectively provided on the outer wall surfaces at both ends of the fixed block. A fixing hole is provided on the side wall surface of each fixing plate. Each fixing plate is threaded to the inside of the pulping machine through the corresponding fixing hole.

[0006] Optionally, the inner wall surface of the fixing block located in the liquid receiving tank is an arc surface.

[0007] Optionally, the bottom of the fixing block inside the liquid receiving tank is inclined, and the lowest point of the bottom of the fixing block is located at the drain outlet, and the highest point is located at the connection between the inner wall surface and the bottom of the fixing block.

[0008] Optionally, connecting pieces are provided on both end faces of the fixing block, and each connecting piece is threadedly connected to each fixing piece; the vertical distance from the outer top of one fixing piece to the outer top of the fixing block is greater than the vertical distance from the outer top of the other fixing piece to the outer top of the fixing block.

[0009] Optionally, a first through hole is provided on the side wall of one of the connecting pieces, and multiple second through holes are provided on the side wall of the corresponding fixing piece. A fixing bolt located inside the first through hole is provided on the side wall of the connecting piece. The fixing bolt is threadedly connected to the corresponding fixing piece through any one of the second through holes to adjust the connection position between the connecting piece and the corresponding fixing piece.

[0010] Optionally, each fixing piece is provided with an L-shaped connecting piece at its top, and each L-shaped connecting piece forms a bayonet with the corresponding fixing piece.

[0011] Optionally, the outer top of the fixing block, located within the liquid receiving tank, has a diameter between the diameter and radius of the corresponding support roller.

[0012] Optionally, the outer wall of the fixing block is also provided with a reinforcing plate that is connected to the outer wall of the connecting piece.

[0013] The beneficial effects of this utility model are:

[0014] A fixing block is installed inside the pulping machine, directly below the support roller. A fixing plate is installed on each end of the outer wall of the fixing block, and a fixing hole is opened on the side wall of each fixing plate. During use, a locking bolt is threaded through the fixing hole on the side wall of the fixing plate, and the locking bolt is then fixed to the internal threads of the pulping machine. Specifically, the connection point is on the bracket inside the pulping machine that supports and rotates the support roller. The slurry collected on the support roller can fall directly onto the top of the fixing block below it during rotation. A liquid receiving groove is opened on the top of the fixing block facing the support roller. When the slurry falls from the surface of the support roller, it can fall directly into the liquid receiving groove on the top of the fixing block and be collected, preventing the slurry from falling onto the crossbeam inside the pulping machine, which would not only affect product quality but also the normal operation of the pulping machine. A drain outlet connected to the liquid receiving tank is opened at the bottom of the fixed block. The slurry collected in the liquid receiving tank at the top of the fixed block can be drained through the drain outlet. After the slurry is drained, the water outlet pipe connected to the drain outlet can discharge the slurry to other places to avoid affecting the product quality and the normal use of the pulping machine.

[0027] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0028] The following disclosure provides many different embodiments or examples for implementing various structures of this invention. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of this invention.

[0029] The embodiments of the utility model will now be described in detail with reference to the accompanying drawings.

[0030] Example 1

[0031] Please see Figure 1 , Figure 2 and Figure 7 As shown, this embodiment discloses a water-receiving device for the wet end support roller of a pulping machine, including a fixing block 1. A fixing piece 2 is respectively provided on the outer wall surface of both ends of the fixing block 1. A fixing hole 20 is opened on the side wall surface of each fixing piece 2, so that the two fixing pieces 2 can be fixed inside the pulping machine through the corresponding fixing hole 20. The specific fixing position of the fixing piece 2 is located in the support bracket inside the pulping machine used to rotatably connect and support the support roller. It is worth noting that the support bracket and support roller inside the pulping machine are both disclosed in the prior art and are technical contents well known to those skilled in the art. They will not be described in detail here. A liquid receiving trough 10 is provided at the end of the fixed block 1 facing the support roller, and a drain outlet 11 connected to the liquid receiving trough 10 is provided at the bottom of the fixed block 1. During the operation of the pulping machine, the slurry adhering to the surface of the support roller falls directly into the liquid receiving trough 10 at the top of the fixed block 1 for collection. The slurry in the liquid receiving trough 10 is then discharged from the drain outlet 11 of the fixed block 1. This prevents the slurry from falling directly from the surface of the support roller onto the crossbeams and forming screen inside the pulping machine, thus avoiding impacts on the use of the pulping machine and product quality. When the slurry is discharged from the drain outlet 11, this slurry can be recycled and reused. A water outlet pipe 3 connected to the drain outlet 11 is connected to the bottom of the fixed block 1, and the other end of the water outlet pipe 3 extends to and connects to the recycling system for secondary recycling of the slurry.

[0032] After the slurry on the surface of the support roller falls into the liquid receiving tank 10, it gathers in the tank until it covers the bottom of the fixed block 1. Only then will the slurry be discharged from the drain outlet 11 at the bottom of the fixed block 1. To achieve this, an inclined surface is provided on the bottom of the fixed block 1 in the liquid receiving tank 10. The highest point of the inclined surface is located at the connection between the bottom of the fixed block 1 in the liquid receiving tank 10 and the inner wall of the fixed block 1 in the liquid receiving tank 10, and the lowest point is located at the inlet of the drain outlet 11 at the bottom of the fixed block 1. When the slurry falls from the surface of the support roller into the liquid receiving tank 10, it will flow in the bottom of the liquid receiving tank 10 with a certain inclination and be discharged from the drain outlet 11. That is, the slurry in the liquid receiving tank 10 will not accumulate too much in one place and cannot be completely discharged from the drain outlet 11. In addition, the inner wall surface of the fixing block 1 located in the liquid receiving tank 10 is set as an arc surface. The arc surface setting can prevent the liquid receiving tank 10 from having too many dead corners where slurry accumulates, and avoid the slurry from not being able to be discharged normally through the drain outlet 11 for a long time in the dead corners, which would reduce the available flow space in the liquid receiving tank 10.

[0033] Example 2

[0034] This embodiment is a further optimization based on Embodiment 1. Specifically, as follows: Figure 3-5 As shown, connecting pieces 4 are provided on the two outer walls of the fixed block 1. The connecting pieces 4 are threadedly connected to the corresponding fixed pieces 2. The vertical distance between the outer top of the fixed piece 2 and the outer top of the fixed block 1 is greater than the vertical distance between the outer top of the other fixed piece 2 and the top of the fixed block 1. That is, the two fixed pieces 2 are fixed in different positions inside the pulping machine. The purpose is to make the liquid receiving tank 10 inside the fixed block 1 present an overall inclined state. Compared with the above method of adjusting the inner bottom of the fixed block 1 in the liquid receiving tank 10 to be inclined, this method only needs to adjust the inclination angle of the fixed block 1 to meet the flow of pulp in the liquid receiving tank 10, thus reducing the processing cost.

[0035] A first through hole 40 is opened on the side wall of the connecting piece 4, and multiple second through holes are opened on the fixing piece 2, which is fixedly connected to the connecting piece 4. A fixing bolt 41 is threadedly connected to the side wall of the connecting piece 4 through the first through hole 40. The fixing bolt 41 can be threadedly connected to the fixing piece 2 through any one of the multiple second through holes. That is, after the fixing pieces 2 at both ends of the fixing block 1 are fixedly connected to the brackets used to support the support rollers in the pulping machine, the fixing bolts 41 are tightened by corresponding to the first through hole 40 and different second through holes, allowing the fixing block 1 to present different tilt angles. Specifically, when the fixing bolt 41 is threadedly connected to the uppermost second through hole among the multiple second through holes through the first through hole 40, the fixing block 1 is in a horizontal state. The slurry falling into the liquid receiving tank 10 needs to be moved and covered at the bottom of the liquid receiving tank 10 until the slurry can enter the drain outlet 11 before it can be discharged. If the fixing block 1 needs to be adjusted to a certain tilt angle, the fixing bolt 41 is adjusted and tightened between the first through hole 40 and the second through hole. At this time, the fixing block 1 will have a certain tilt angle, which allows the slurry entering the liquid receiving tank 10 to flow directly towards the drain outlet 11 and finally be discharged from the drain outlet 11. It is worth noting that the drain outlet 11 and the connecting piece 4 are located at the same end of the fixing block 1 to prevent the adjustment of the fixing block 1 from causing the slurry to flow away from the drain outlet 11, which would prevent the slurry from being discharged from the drain outlet 11 inside the liquid receiving tank 10. In addition, the first through hole 40 and the second through hole can meet the position adjustment of the fixing bolt 41. That is, when the fixing block 1 needs to be tilted, the central axis of the first through hole 40 on the connecting piece 4 is parallel to but does not coincide with the central axis of the second through hole in the vertical direction. In this case, the inner diameter of the first through hole 40 and the second through hole needs to be extended so that the fixing bolt 41 can be threadedly connected to the fixing piece 2 after the fixing block 1 is rotated to any angle.

[0036] Example 3

[0037] This embodiment is a further optimization based on Embodiment 2. Specifically, as follows: Figure 3 , Figure 4 and Figure 6 As shown, an L-shaped connecting piece 5 is provided on the top of each of the above-mentioned fixing pieces 2. The short side of the L-shaped connecting piece 5 is connected to the outer top of the fixing piece 2, so that a bayonet 6 is formed between the L-shaped connecting piece 5 and the fixing piece 2. This bayonet 6 can be adapted to the support used to rotate and connect the support roller in the pulping machine. On the one hand, it can make the liquid receiving groove 10 in the fixing block 1 closer to the surface of the support roller, which is convenient for collecting the fallen pulp. On the other hand, it can fix the connection stability of the piece 2 on the support frame. It should be noted that the L-shaped connecting piece 5 and the fixing piece 2 are integrally formed.

[0038] The inner diameter of the fixed block 1 at the top and at the entrance of the liquid receiving tank 10 is between the diameter and radius of the corresponding support roller. This means that when the slurry attached to and falling off the surface of the support roller enters the liquid receiving tank 10, it can prevent the slurry from not falling into the liquid receiving tank 10 because the inner diameter of the opening of the liquid receiving tank 10 at the top of the fixed block 1 is too small.

[0039] A reinforcing plate 7 is provided on the outer wall surface of the fixing block 1 where the connecting piece 4 is located. The reinforcing plate 7 is connected to the connecting piece 4 and can strengthen the connecting piece 4.

[0040] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and variations. Without conflict, the embodiments and features described in the embodiments of this application can be arbitrarily combined with each other. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
