Description

Technical Field

[0001] This utility model relates to the field of slurry skimming technology, and more specifically, to a slurry skimming tank and slurry skimming equipment having the same. Background Technology

[0002] Pulp molding, as an environmentally friendly packaging material production technology, has received widespread attention and application in recent years. It involves shaping pulp in a specially designed mold, followed by dewatering and drying processes to ultimately produce packaging products with high strength, lightweight, and biodegradability. The pulp skimming tank is an indispensable and important component of pulp molding equipment, primarily used for the pulp shaping and initial dewatering stages. However, existing pulp skimming tanks suffer from several major technical problems:

[0003] 1. Insufficient strength of the slurry tank: Traditional slurry tanks are often constructed by splicing and welding together sheet metal. While this method can meet basic usage requirements, the tank is prone to cracking and leakage under prolonged vibration and liquid impact. Insufficient strength not only affects production continuity and product quality but also increases the need for frequent maintenance, thereby raising operating costs.

[0004] 2. High complexity of piping systems: To achieve pulp inlet, outlet, and overflow, existing pulp tanks are typically equipped with complex piping systems, including inlet pipes, overflow pipes, and suction pipes. These pipes require precise welding and installation on-site, which not only increases the manufacturing cost of the equipment but also makes maintenance and replacement extremely inconvenient in case of failure, sometimes even requiring the disassembly of the entire pulp tank, severely impacting production efficiency.

[0005] 3. Low maintenance and assembly efficiency: Due to the aforementioned problems, the existing slurry skimming tanks have a short maintenance cycle, and each maintenance requires a considerable amount of time. Furthermore, on-site welding of pipelines not only prolongs assembly time but may also lead to additional debugging and inspection work due to uncertainties in welding quality, further reducing the equipment's assembly efficiency.

[0006] In response to the above problems, there is an urgent market demand for new types of slurry skimming tanks that can improve strength, simplify piping systems, and reduce maintenance and assembly workload. Utility Model Content

[0007] The main objective of this invention is to provide a slurry skimming tank and slurry skimming equipment thereon, in order to solve the problems of insufficient strength of the slurry skimming tank, high complexity of the pipeline system, and low assembly efficiency caused by on-site welding of pipelines to the slurry skimming tank in the prior art.

[0008] To achieve the above objectives, according to one aspect of the present invention, a slurry skimming tank is provided, comprising:

[0009] The main body of the slurry trough;

[0010] The slurry inlet pipe is located at the bottom of the slurry tank body and is connected to the slurry tank body to deliver slurry into the slurry tank body through the slurry inlet pipe;

[0011] The slurry discharge port is located at the bottom of the slurry trough and is connected to it to discharge the slurry after slurry removal;

[0012] The suction pipe is located at the bottom of the pulp tank body and connected to it. The outlet end of the suction pipe is used to connect to the pulp mold to deliver a vacuum into the pulp mold so that the pulp fibers in the pulp liquid form a preliminary wet blank in the pulp mold under the action of vacuum.

[0013] The slurry inlet pipe and the slurry suction pipe are integrally formed with the slurry collection tank body.

[0014] Furthermore, the slurry skimming tank also includes: at least one flow pipe disposed within the slurry skimming tank body, each flow pipe having a first opening connected to the outlet end of the slurry inlet pipe;

[0015] Multiple overflow ports are provided on at least one flow pipe and connected to the slurry collection tank body, so that the slurry in the at least one flow pipe overflows from the multiple overflow ports into the slurry collection tank body;

[0016] At least one flow pipe is integrally formed with the slurry collection tank body.

[0017] Furthermore, the flow conduit includes: at least two first flow pipes arranged along the length of the slurry tank body, and multiple overflow ports respectively provided on each of the first flow pipes;

[0021] The second pipe wall has one side edge connected to the side edge of the first pipe wall away from the bottom wall, and the side edge of the second pipe wall away from the first pipe wall is connected to the first side wall of the slurry tank body.

[0022] Multiple overflow ports are located on the first pipe wall, and the first pipe wall and the bottom wall, the second pipe wall and the first pipe wall, and the second pipe wall and the first side wall are all integrally formed.

[0023] Furthermore, a first included angle is formed between the first pipe wall and the bottom wall, and the first included angle is a right angle;

[0024] A second included angle is formed between the edge of the second pipe wall and the edge of the first pipe wall furthest from the bottom wall;

[0025] The second included angle is between 140° and 160°.

[0026] Furthermore, the second flow pipe includes: a third pipe wall, which is disposed on the bottom wall of the slurry tank body;

[0027] The fourth pipe wall has one side edge connected to the side edge of the third pipe wall away from the bottom wall, and the side edge of the fourth pipe wall away from the third pipe wall is connected to the second side wall of the slurry tank body.

[0028] The third pipe wall and the bottom wall, the fourth pipe wall and the third pipe wall, and the fourth pipe wall and the second side wall are all integrally formed.

[0029] Furthermore, a third included angle is formed between the third pipe wall and the bottom wall, and this third included angle is a right angle;

[0030] A fourth angle is formed between the edge of the fourth pipe wall and the edge of the third pipe wall furthest from the bottom wall;

[0031] The fourth included angle is between 140° and 160°.

[0032] Furthermore, the slurry trough also includes: at least two buffer baffles, which are disposed in the slurry trough body and form overflow spaces with the two first side walls respectively, and the at least two buffer baffles are arranged along the length direction of the slurry trough body;

[0033] Among them, at least two buffer baffles together form a slurry scooping space, so that when the liquid level of the slurry is higher than the height of the buffer baffle along the thickness direction of the slurry scooping tank, it flows into the overflow space.

[0034] Furthermore, the slurry skimming tank also includes: an overflow pipe, which is located outside the slurry skimming tank body and communicates with the overflow space to draw the slurry that has entered the overflow space out of the overflow space;

[0035] The overflow pipe and the slurry collection tank are integrally formed.

[0036] Furthermore, the slurry collection tank body includes: two first sidewalls arranged opposite to each other, the two first sidewalls being arranged along the length direction of the slurry collection tank body;

[0037] Two opposing second sidewalls are arranged along the width of the slurry trough body;

[0038] A connecting wall is provided between the adjacent first sidewall and the second sidewall. The included angle formed between the first sidewall and the connecting wall and the second sidewall and the connecting wall are equal, and the included angle ranges between 130° and 160°.

[0039] Furthermore, the buffer plate is a rectangular plate, and the side of the buffer plate extending along the thickness direction of the slurry tank body is connected to the connecting wall.

[0040] According to another aspect of the present invention, a slurry skimming device is provided, which includes a slurry skimming tank, wherein the slurry skimming tank is the slurry skimming tank described above.

[0041] Applying the technical solution of this utility model, the slurry skimming tank provided in this application includes a slurry skimming tank body. A slurry inlet pipe is provided at the bottom of the slurry skimming tank body and communicates with it, through which slurry is transported into the slurry skimming tank body. A slurry outlet is also provided at the bottom of the slurry skimming tank body and communicates with it, allowing the skimmed slurry to be discharged to the outside. A slurry suction pipe is also provided at the bottom of the slurry skimming tank body. The inlet end of the suction pipe is used to communicate with a vacuum device, and the outlet end is used to communicate with a slurry skimming mold. When skimming slurry, the vacuum device is turned on. Vacuum is delivered to the pulping mold via a suction pipe. During the process of vacuum delivery to the pulping mold, the pulp fibers in the pulp form a preliminary wet blank within the pulping mold under the action of vacuum. The inlet pipe and suction pipe are integrally formed with the pulping tank body. This integral forming means excluding welding. In this application, the outlet end of the suction pipe is connected to the pulping mold via a flexible steel wire hose, so that during use, only the suction pipe needs to be connected to the pulping mold without connecting other components.

[0042] As a core component in the pulp molding process, the pulp tank body is designed using a one-piece molding technology. This means that the entire tank body has no welding points, thereby improving the overall strength and durability of the structure. By reducing seams and welding points, the sealing performance of the pulp tank body is enhanced, effectively preventing pulp leakage under high-intensity use.

[0043] The slurry inlet pipe and the slurry collection tank body are integrally molded and directly connected to the bottom of the slurry collection tank body. This not only simplifies the installation process of the slurry inlet system but also avoids the risk of pipe blockage or leakage caused by welding. The direct connection design of the slurry inlet pipe ensures a stable input of slurry, reduces pressure loss during transportation, and helps to form a stable liquid level and concentration.

[0044] The slurry discharge port is also located at the bottom of the slurry tank. Its design allows the slurry to be discharged quickly and thoroughly after the slurry removal process, avoiding cleaning difficulties and bacterial growth caused by slurry residue. Rapid slurry discharge from the discharge port effectively shortens the equipment cleaning cycle and reduces production losses due to equipment downtime.

[0045] The suction pipe and the pulp collection tank are integrally molded, reducing the complexity caused by the combination of multiple parts in traditional designs. This design not only simplifies the connection method and improves the overall assembly efficiency of the equipment, but also makes vacuum suction more uniform and effective, ensuring that the initial wet preform formed in the pulp collection mold has a more consistent thickness and density, thereby improving the quality and production consistency of pulp molding products.

[0046] Under vacuum, pulp fibers are able to form a preliminary wet preform within the pulping mold, which depends on the effective transfer of vacuum through the suction pipe. The integrated suction pipe and tank body ensure the continuity and effectiveness of vacuum suction, thereby improving the adsorption efficiency and quality of pulp fibers, reducing fiber waste, and increasing raw material utilization.

[0047] By molding the slurry inlet pipe, slurry suction pipe, and slurry collection tank into a single unit, eliminating the need for welding, the structural strength and sealing of the entire system are enhanced. This also simplifies the manufacturing and maintenance process, reduces potential quality problems caused by welding, and achieves higher production standards. Attached Figure Description

[0054] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0055] As mentioned in the background section, the main objective of this utility model is to provide a slurry skimming tank and slurry skimming equipment having the same, so as to solve the problems of insufficient strength of the slurry skimming tank, high complexity of the pipeline system and low assembly efficiency caused by on-site welding of pipelines to the slurry skimming tank in the prior art.

[0056] This application first provides a slurry skimming tank, including a slurry skimming tank body 1;

[0057] The slurry inlet pipe 2 is located at the bottom of the slurry tank body 1 and is connected to the slurry tank body 1 so as to deliver slurry into the slurry tank body 1 through the slurry inlet pipe 2;

[0058] The slurry discharge port 3 is located at the bottom of the slurry trough body 1 and is connected to it to discharge the slurry after slurry removal;

[0059] The suction pipe 4 is located at the bottom of the pulp tank body 1 and is connected to it. The outlet end of the suction pipe 4 is used to connect to the pulp mold to deliver a vacuum into the pulp mold so that the pulp fibers in the pulp liquid form a preliminary wet blank in the pulp mold under the action of vacuum.

[0060] The slurry inlet pipe 2 and the slurry suction pipe 4 are integrally formed with the slurry collection tank body 1.

[0061] To facilitate understanding, the molding principle of paper-plastic products will be explained first. The molding process of paper-plastic products generally consists of three steps: pulp forming, cold pressing, and hot pressing.

[0062] Pulp-skimming molding involves placing a pulp-skimming mold in slurry and forming a preliminary wet preform with the product's outline shape through vacuuming. This preform is then transferred to a cold-pressing mold, where the upper and lower molds press together to form a preform body. Finally, a hot-pressing mold dehydrates the preform body, resulting in a paper-plastic product. This process involves preform formation and continuous dehydration. Pulp-skimming molding removes free water from the surface of the preform, but the dehydration effect is limited, typically removing only about 20%. Cold-pressing molding also removes free water from the surface, but the dehydration effect is significantly higher, typically removing about 50% of the free water to obtain the preform body. Hot-pressing molding removes bound water from within the preform body, using heat to vaporize the free water on the surface and the bound water inside, resulting in a paper-plastic product with a final moisture content below 3%.

[0063] This application addresses the product slurry forming stage, employing a slurry forming mold to achieve wet preform forming. The specific structure is mainly as follows:

[0064] like Figures 1 to 3As shown, the slurry skimming tank provided in this application includes a slurry skimming tank body 1. A slurry inlet pipe 2, connected to the bottom of the slurry skimming tank body 1, is provided to supply slurry into the slurry skimming tank body 1. A slurry discharge port 3, also connected to the bottom of the slurry skimming tank body 1, is provided to discharge the skimmed slurry to the outside. A slurry suction pipe 4 is also provided at the bottom of the slurry skimming tank body 1. The inlet end of the suction pipe 4 is connected to a vacuum device, and the outlet end of the suction pipe 4 is connected to a slurry skimming mold. When skimming slurry, the vacuum device is turned on, and the slurry is discharged through the vacuum device. The suction pipe 4 delivers vacuum to the pulping mold. During the process of vacuum delivery to the pulping mold, the pulp fibers in the pulp form a preliminary wet blank in the pulping mold under the action of vacuum. The inlet pipe 2 and the suction pipe 4 are integrally formed with the pulping tank body 1. The integral forming here means that welding is excluded. The outlet end of the suction pipe 4 in this application is connected to the pulping mold by a steel wire hose, so that when in use, only the suction pipe 4 needs to be connected to the pulping mold, without the need to connect other parts.

[0065] As a core component in the pulp molding process, the pulp tank body 1 is designed using a one-piece molding technology. This means that the entire tank has no welding points, thereby improving the overall strength and durability of the structure. Due to the reduction of seams and welding points, the sealing performance of the pulp tank body 1 is enhanced, effectively preventing pulp leakage under high-intensity use.

[0066] The slurry inlet pipe 2 and the slurry collection tank body 1 are integrally molded and directly connected to the bottom of the slurry collection tank body 1. This not only simplifies the installation process of the slurry inlet system but also avoids the risk of pipe blockage or leakage caused by welding. The direct connection design of the slurry inlet pipe 2 ensures a stable input of slurry, reduces pressure loss during transportation, and is conducive to forming a stable liquid level and concentration.

[0067] The slurry discharge port 3 is also located at the bottom of the slurry tank body 1. Its design allows the slurry to be discharged quickly and thoroughly after the slurry removal process is completed, avoiding cleaning difficulties and bacterial growth caused by slurry residue. The rapid discharge of slurry through the discharge port 3 can effectively shorten the equipment cleaning cycle and reduce production losses caused by equipment downtime.

[0068] The suction pipe 4 is integrally formed with the pulp collection tank body 1, reducing the complexity caused by the combination of multiple parts in traditional designs. This design not only simplifies the connection method and improves the overall assembly efficiency of the equipment, but also makes the vacuum suction more uniform and effective, ensuring that the initial wet preform formed in the pulp collection mold has a more consistent thickness and density, thereby improving the quality and production consistency of pulp molding products.

[0069] Under vacuum, pulp fibers are able to form a preliminary wet preform within the pulping mold, which relies on the effective transfer of vacuum by the suction pipe 4. The integrally molded suction pipe 4, combined with the tank body, ensures the continuity and effectiveness of vacuum suction, thereby improving the adsorption efficiency and quality of pulp fibers, reducing fiber waste, and increasing raw material utilization.

[0070] The slurry inlet pipe 2, slurry suction pipe 4 and slurry collection tank body 1 are integrally formed, eliminating the need for welding. This not only enhances the structural strength and sealing of the entire system, but also simplifies the manufacturing and maintenance process of the equipment, reduces potential quality problems caused by welding, and achieves higher quality production standards.

[0071] Furthermore, the slurry skimming tank also includes:

[0072] At least one flow pipe 5 is provided inside the slurry tank body 1, and each flow pipe 5 is provided with a first opening, which is connected to the outlet end of the slurry inlet pipe 2.

[0073] Multiple overflow ports 501 are provided on at least one flow pipe 5 and connected to the slurry tank body 1, so that the slurry in the at least one flow pipe 5 overflows from the multiple overflow ports 501 into the slurry tank body 1.

[0074] At least one flow pipe 5 is integrally formed with the slurry collection tank body 1.

[0075] Example 1

[0076] The slurry collection tank also includes a flow pipe 5 disposed within the slurry collection tank body 1. When there is only one flow pipe 5, a first opening is disposed on the flow pipe 5 and the first opening is connected to the outlet end of the slurry inlet pipe 2. Multiple overflow ports 501 are disposed on the flow pipe 5, and each overflow port 501 is connected to the interior of the slurry collection tank body 1. When the slurry enters from the slurry inlet pipe 2, it will enter the flow pipe 5 connected to it. The slurry in the flow pipe 5 will flow into the slurry collection tank body 1 from the multiple overflow ports 501. The flow pipe 5 and the slurry collection tank body 1 are integrally formed, and the integral forming here is set to exclude welding.

[0077] In Example 1, there is one flow pipe 5. The arrangement of the flow pipe 5 allows the slurry to be evenly distributed inside the slurry collection tank body 1 through multiple overflow ports 501, promoting rapid and stable flow of the slurry and improving the uniformity and efficiency of slurry distribution. The one-piece molding design further reduces potential failure points between the flow pipe 5 and the slurry collection tank body, enhancing the overall integrity of the system.

[0078] The connection between each overflow port 501 and the interior of the slurry tank body 1 ensures that the slurry can overflow evenly in the flow pipe 5, covering the entire bottom surface of the tank. Thus, under the action of the slurry suction pipe 4, a uniformly thick initial wet blank is formed, improving the quality and consistency of the product.

[0079] Example 2

[0080] The difference from Embodiment 1 is that there are multiple flow pipes 5 in this embodiment, and the arrangement of the multiple flow pipes 5 in the slurry tank body 1 is not unique. When there are multiple flow pipes 5, each flow pipe 5 is provided with a first opening. When there is only one slurry inlet pipe 2, the outlet end of the slurry inlet pipe 2 can be connected to each of the first openings through a main conveying pipe, and the slurry is then conveyed to the corresponding flow pipe 5 through each of the first openings through the main conveying pipe. When there are multiple slurry inlet pipes 2, each slurry inlet pipe 2 is connected to a first opening. Each flow pipe 5 is provided with multiple overflow ports 501, wherein the multiple flow pipes 5 are integrally formed with the slurry tank body 1.

[0081] In this application, the number of flow channels 5 is one, and the number of first openings is one.

[0082] In Example 2, when there is one slurry inlet pipe 2 and multiple flow pipes 5, the presence of the main delivery pipe ensures that the slurry can be distributed to each flow pipe 5. This design overcomes the uneven slurry distribution that may be caused by a single slurry inlet.

[0083] In Example 2, the multiple flow pipes 5 are integrally formed with the slurry tank body 1. This design not only optimizes the flow path of the slurry in the tank and improves the uniformity of slurry distribution, but also reduces the additional costs and maintenance complexity caused by multi-point welding and enhances the reliability of the system.

[0084] Whether it is a single flow pipe 5 in Example 1 or multiple flow pipes 5 in Example 2, the presence of the first opening ensures that the slurry can smoothly enter the flow pipe 5 from the slurry inlet pipe 2, thus ensuring a stable input of the slurry.

[0085] When there are multiple slurry inlet pipes 2, each slurry inlet pipe 2 is connected to a first opening. This design allows the slurry to be more precisely distributed to each flow pipe 5, further improving the uniformity of slurry distribution and molding quality.

[0086] By integrating the slurry inlet pipe 2, the flow pipe 5, and the slurry collection tank body 1 into a single unit (excluding welding), the manufacturing and assembly process of the equipment is simplified, and the risk of slurry leakage and system failure during the production process is significantly reduced.

[0087] Furthermore, the flow channel 5 includes:

[0088] At least two first flow pipes 502 are arranged along the length of the slurry tank body 1, and multiple overflow ports 501 are respectively provided on each first flow pipe 502.

[0089] At least two second flow pipes 503 are arranged along the width direction of the slurry tank body 1;

[0090] The interior of the first flow tube 502 is connected to the interior of the second flow tube 503.

[0091] Specifically, the flow conduit 5 includes at least two first flow pipes 502, which are arranged along the length of the slurry tank body 1. Multiple overflow ports 501 are respectively provided on each first flow pipe 502. It also includes at least two second flow pipes 503, which are arranged along the width direction of the slurry tank body 1. In this embodiment, there are two first flow pipes 502 and two second flow pipes 503. The interiors of the first flow pipes 502 and the second flow pipes 503 are in communication. Figure 1 As shown, a buffer pipe is also provided between adjacent first flow pipes 502 and second flow pipes 503. In the conventional connection method, the included angle between adjacent first flow pipes 502 and second flow pipes 503 is a right angle. However, this connection method is prone to damage at the connection between the first flow pipes 502 and second flow pipes 503. The connection method in this application makes the included angle between the first flow pipes 502 and second flow pipes 503 obtuse due to the presence of the buffer pipe, thereby avoiding damage at the connection between the first flow pipes 502 and second flow pipes 503 when the flow rate of the slurry is too high.

[0092] The one-piece molded slurry tank body 1 design eliminates the traditional welding method, ensuring the structural integrity and high sealing performance of the tank, thereby improving the durability and operational safety of the tank, reducing the frequency of maintenance, and providing a solid foundation for the continuity and efficiency of the entire production process.

[0093] Two first flow pipes 502 are arranged along the length of the slurry tank body 1, and each pipe is provided with multiple overflow ports 501. This design ensures that the slurry can flow out evenly across the width of the slurry tank body 1. Two second flow pipes 503 are arranged along the width of the slurry tank body 1 and are connected to the interior of the first flow pipes 502 to form a complete flow pipeline 5.

[0094] A buffer pipe is installed between adjacent first flow pipes 502 and second flow pipes 503, changing the traditional right-angle connection layout and making the included angle at the connection point obtuse. This design significantly reduces stress concentration at the connection point, prevents damage to the pipe connection when the slurry flow rate is too high, enhances the overall stability and durability of the flow pipe system, and reduces downtime caused by pipe damage during production.

[0095] The overflow port 501 on each first flow pipe 502 ensures that the slurry can overflow from the flow pipe 5 into the slurry tank body 1, evenly covering the bottom of the tank, thus improving the utilization efficiency of the slurry.

[0096] The internal connection design of the first flow tube 502 and the second flow tube 503 ensures that the pulp can form a continuous flow network within the pulp tank body 1, eliminating dead zones in the pulp flow, improving the flow efficiency of the pulp within the tank, reducing air bubbles and impurities in the pulp, and further enhancing the purity and forming effect of the pulp products.

[0097] The buffer pipe makes the connection between the first flow pipe 502 and the second flow pipe 503 obtuse. This design improves the flow curve of the slurry at the pipe transition point, reduces fluid resistance, and allows the slurry to flow more smoothly in the slurry tank body, avoiding turbulence and slurry accumulation, and enhancing the uniformity and continuity of slurry distribution.

[0098] The one-piece molding design, combined with the obtuse angle connection of the buffer pipe, not only improves the structural strength and sealing of the flow pipe 5, but also optimizes the flow path of the slurry in the slurry tank body 1, reducing the failure rate and maintenance cost in the production process.

[0099] Furthermore, the first flow tube 502 includes:

[0100] The first pipe wall 5021 is provided on the bottom wall 101 of the slurry tank body 1;

[0101] The second pipe wall 5022 has one side edge connected to the side edge of the first pipe wall 5021 away from the bottom wall 101, and the side edge of the second pipe wall 5022 away from the first pipe wall 5021 is connected to the first side wall 102 of the slurry tank body 1.

[0102] Multiple overflow ports 501 are provided on the first pipe wall 5021. The first pipe wall 5021 and the bottom wall 101, the second pipe wall 5022 and the first pipe wall 5021, and the second pipe wall 5022 and the first side wall 102 are all integrally formed.

[0103] Specifically, from Figure 3 As can be seen, the first pipe wall 5021 is set perpendicular to the bottom wall 101.

[0104] Furthermore, a first included angle is formed between the first pipe wall 5021 and the bottom wall 101, and the first included angle is a right angle;

[0105] A second included angle is formed between the edge of the second pipe wall 5022 and the edge of the first pipe wall 5021 that is away from the bottom wall 101;

[0106] The second included angle is between 140° and 160°.

[0107] The design of the slurry collection tank body 1 adopts a one-piece molding technology, which greatly enhances the structural integrity and sealing performance of the tank. One-piece molding eliminates potential leaks and structural weaknesses caused by welding and other connection methods, ensuring that the slurry collection tank body 1 maintains a good sealing condition even under high-pressure slurry environments. This improves the durability and operational safety of the equipment, and reduces maintenance costs and the risk of production interruptions.

[0108] The first flow pipe 502 is composed of a first pipe wall 5021 and a second pipe wall 5022, and is set perpendicular to the bottom wall 101. This design ensures that the slurry can rise vertically and be evenly distributed inside the slurry collection tank body 1 through the overflow port 501. At the same time, the integral molding connection between the first flow pipe 502 and the bottom wall 101 and the first side wall 102 reduces weak points in the structure, enhances the stability and sealing of the entire flow system, and reduces slurry loss during the transmission process.

[0109] Multiple overflow ports 501 are provided on the first pipe wall 5021, which is perpendicular to the bottom wall 101. This design ensures that the pulp can be diffused to every corner of the pulp tank body 1 with minimal turbulence and maximum uniformity through the vertically rising pulp, thereby improving the uniformity and consistency of pulp molding products during the molding process, reducing product defects caused by uneven pulp distribution, and improving overall production efficiency and quality.

[0110] The integral molding connection between the second pipe wall 5022, the first pipe wall 5021, and the first side wall 102 ensures the integrity of the flow pipe 5, reduces leakage during the slurry flow process, and optimizes the fluid dynamics characteristics, enabling the slurry to pass through the first flow pipe 502 smoothly and quickly, thereby improving the slurry treatment efficiency.

[0111] The overflow port 501 is directly set on the first pipe wall 5021. This design utilizes the kinetic energy of the vertically rising slurry to ensure that the slurry can overflow evenly and cover the entire bottom wall 101, reducing the accumulation of slurry in local areas, avoiding poor molding caused by uneven slurry distribution, and improving product quality and production efficiency.

[0112] Furthermore, the second flow tube includes:

[0113] The third pipe wall is located on the bottom wall 101 of the slurry tank body 1;

[0114] The fourth pipe wall has one side edge connected to the side edge of the third pipe wall away from the bottom wall 101, and the side edge of the fourth pipe wall away from the third pipe wall is connected to the second side wall 103 of the slurry tank body 1.

[0115] The third pipe wall and the bottom wall 101, the fourth pipe wall and the third pipe wall, and the fourth pipe wall and the second side wall 103 are all integrally formed.

[0116] Specifically, the third pipe wall is set perpendicular to the bottom wall 101.

[0117] The slurry collection tank body 1 adopts a one-piece molding technology. This design not only ensures the overall sealing of the slurry collection tank body 1, but also significantly improves the structural strength and durability of the equipment. One-piece molding eliminates the potential leakage and structural weaknesses at the joints caused by traditional welding or other connection methods, thus making the entire equipment more stable under high-pressure slurry and frequent use, reducing maintenance and downtime, and enhancing production continuity and efficiency.

[0118] The design of the second flow pipe encompasses a third and a fourth pipe wall, with the third pipe wall positioned perpendicular to the bottom wall 101. This design ensures efficient vertical flow of the slurry, reduces turbulence, and optimizes the uniformity of slurry distribution. The integrally formed connection between the flow pipe 5 and the bottom wall 101 and second side wall 103 of the slurry collection tank body 1 further enhances the integrity and sealing of the flow pipe 5, reducing the risk of slurry leakage.

[0119] The fourth pipe wall, which is tightly connected to the third pipe wall and the second side wall 103 of the slurry tank body 1, is integrated with the slurry tank body 1 and the third pipe wall into a robust whole through integral molding technology. This design enhances the structural stability and sealing of the second flow pipe, ensures the smooth flow of slurry in the pipeline, reduces the impact of flow rate changes on the uniformity of slurry distribution, and ensures the consistency and high quality of product molding.

[0120] By integrally connecting the third and fourth pipe walls of the second flow pipe with the bottom wall 101 and the second side wall 103 of the pulp tank body 1, and by setting the third pipe wall perpendicular to the bottom wall 101, the flow characteristics of the pulp are optimized, the sealing performance and structural stability of the equipment are improved, and pulp waste and equipment failures during the production process are reduced, thereby improving the quality and production efficiency of pulp molding products.

[0121] Furthermore, a third included angle is formed between the third pipe wall and the bottom wall 101, and the third included angle is a right angle;

[0122] A fourth included angle is formed between the edge of the fourth pipe wall and the edge of the third pipe wall on the side away from the bottom wall 101;

[0123] The fourth included angle is between 140° and 160°.

[0124] The third pipe wall and the bottom wall 101 form a right-angle connection. This design utilizes the stability characteristics of a right angle, ensuring smooth flow of the slurry in the vertical direction while also strengthening the stability of the contact area between the flow pipeline and the bottom surface of the slurry tank body 1. The right-angle design not only facilitates the vertical rise of the slurry and reduces frictional losses when the fluid changes direction, but also enhances the load-bearing capacity of the structure and improves the durability of the equipment.

[0125] Instead of a traditional right angle, the fourth pipe wall connects to the third pipe wall at an obtuse angle. This design aims to improve the flow characteristics of the slurry at bends, reduce flow resistance, and avoid the impact of high-speed flowing slurry on the connection, effectively preventing damage and leakage at the pipe wall connection. The obtuse angle design ensures a smooth transition of the slurry, optimizes slurry distribution, and also increases the strength of the structure, improving the operational stability and reliability of the equipment.

[0126] The third included angle of the right-angle structure provides a stable base for the flow tube, ensuring a straight trajectory of the slurry during its ascent, reducing turbulence and agitation, and improving the uniformity of slurry distribution.

[0127] The fourth included angle, between 140° and 160°, effectively mitigates the turning impact in the slurry flow, reduces fluid friction at the turning point, and ensures a smooth fluid transition.

[0128] By using right-angle and obtuse-angle connections, the structural strength of the flow pipeline is significantly enhanced, reducing the probability of equipment failure under high pressure and frequent vibration conditions.

[0129] Furthermore, the slurry skimming tank also includes:

[0130] At least two buffer baffles 6 are provided inside the slurry tank body 1 and form overflow spaces between the two first side walls 102 respectively. At least two buffer baffles 6 are arranged along the length direction of the slurry tank body 1.

[0131] Among them, at least two buffer baffles 6 together form a slurry scooping space, so that when the liquid level of the slurry is higher than the height of the buffer baffles 6 along the thickness direction of the slurry scooping tank body 1, it flows into the overflow space.

[0132] At least two buffer baffles 6 are vertically arranged inside the pulp tank body 1, forming an overflow space between them and the first side wall 102. This design utilizes the buffer baffles 6 to divide the internal space of the pulp tank body 1, creating independent pulp-scouring areas, while retaining the ability of the pulp to freely overflow to the overflow spaces on both sides when its height exceeds the buffer baffles 6. The presence of the buffer baffles 6 optimizes the distribution of pulp within the pulp tank body 1, reduces turbulence and bubble formation, thereby improving the quality of pulp products.

[0133] The space between the buffer baffle 6 and the first sidewall 102 forms an overflow space. When the pulp fills to a height exceeding that of the buffer baffle 6, the excess pulp will naturally flow into the overflow space. This design effectively controls the pulp level, avoiding the risk of overflow caused by excessive pulp accumulation. It also ensures uniform pulp distribution, reduces local oversaturation or dryness of the pulp, and improves the molding consistency and efficiency of pulp molded products.

[0134] The vertical arrangement of the buffer baffle 6 and the overflow space design between it and the first sidewall 102 optimize the fluid dynamics within the pulp tank, effectively disperse the impact force of the pulp, reduce turbulence, and ensure smooth pulp flow. This design improves the controllability of the pulp, helps maintain the stability of pulp concentration and viscosity, and plays a positive role in improving the quality and production efficiency of pulp molding products.

[0135] Furthermore, the slurry skimming tank also includes:

[0136] An overflow pipe 7 is installed outside the slurry tank body 1 and communicates with the overflow space to draw out the slurry that has entered the overflow space.

[0137] The overflow pipe 7 and the slurry trough body 1 are integrally formed.

[0138] The overflow pipe 7 is located outside the slurry tank body 1 and is connected to the overflow space. This design ensures that the slurry can be quickly discharged to the outside when it exceeds the preset height, preventing slurry overflow from affecting the operating environment or equipment performance. The presence of the overflow pipe 7 balances the slurry level in the tank by timely removing excess slurry, avoiding production interruptions and maintaining the uniformity of slurry distribution.

[0139] The integral molding of the overflow pipe 7 and the slurry tank body 1 ensures the stability and sealing of the connection between the two, eliminating slurry loss and equipment failure caused by loose connection points or leakage.

[0140] The design of the overflow pipe 7, through precise connection with the overflow space, improves the hydrodynamic characteristics within the slurry tank. This design optimizes the slurry flow path, reduces backflow and turbulence, ensures uniform slurry distribution within the tank, and guarantees a smooth outflow of slurry during overflow, reducing energy loss during slurry flow and improving slurry treatment efficiency.

[0141] By adding an integrally formed overflow pipe 7 to the outside of the pulp tank body 1 and connecting it to the overflow space, this series of designs jointly optimizes the pulp flow and concentration control, improves the molding quality and production efficiency of pulp molding products, strengthens the structural stability and operational safety of the equipment, and simplifies the maintenance and cleaning process, reflecting the scientific, practical and economical nature of the design.

[0142] Furthermore, the slurry collection tank body 1 includes:

[0143] Two first sidewalls 102 are arranged opposite to each other, and the two first sidewalls 102 are arranged along the length direction of the slurry tank body 1;

[0144] Two second sidewalls 103 are arranged opposite each other, and the two second sidewalls 103 are arranged along the width direction of the slurry tank body 1;

[0145] A connecting wall 104 is provided between adjacent first sidewall 102 and second sidewall 103. The included angle formed between the first sidewall 102 and the connecting wall 104 is equal to the included angle formed between the second sidewall 103 and the connecting wall 104, and the included angle range is between 130° and 160°.

[0146] The pulp tank body 1 adopts an integral design and includes a connecting wall 104 at a specific angle. This design not only ensures the structural stability and sealing of the pulp tank body 1, but also optimizes the flow characteristics of the pulp in the pulp tank body 1 by adjusting the included angle between the first side wall 102 and the second side wall 103, reducing eddies and pulp retention, and improving the quality and consistency of the pulp molding product.

[0147] The setting of the connecting wall 104, especially the obtuse angle design formed with the first side wall 102 and the second side wall 103, with the included angle ranging from 130° to 160°, effectively disperses the pressure and impact of the slurry on the side wall of the slurry tank body 1, reduces the deformation of the side wall caused by uneven stress, enhances the structural rigidity and durability of the slurry tank body 1, and reduces the equipment failure rate.

[0148] The angle between the first sidewall 102 and the connecting wall 104 is equal to the angle between the second sidewall 103 and the connecting wall 104, and both are obtuse angles. Logical reasoning shows that this design aims to achieve balanced flow of slurry in different directions, reduce dead angles in slurry flow, promote the full spreading of slurry inside the slurry tank body 1, and help form a wet blank with uniform thickness and density.

[0149] The obtuse angle connection design improves the fluid dynamics characteristics within the slurry collection tank, reduces turbulence and energy loss of the slurry at the turning point, and ensures smooth flow of the slurry within the slurry collection tank body 1.

[0150] Furthermore, the buffer plate 6 is a rectangular plate, and the side of the buffer plate 6 extending along the thickness direction of the slurry tank body 1 is connected to the connecting wall 104.

[0151] The direct connection between the buffer baffle 6 and the connecting wall 104 forms a stable structural frame. This design not only enhances the support of the buffer baffle 6 and prevents deformation under slurry pressure, but also reduces the number of connection points between the buffer baffle 6 and the slurry tank body 1, simplifies the manufacturing process of the equipment, reduces the potential risk of leakage, and improves the sealing performance of the equipment.

[0152] The robust connection between the buffer baffle 6 and the connecting wall 104 enhances the structural stability of the equipment. This design reduces the risk of damage to the equipment under high-frequency vibration, ensures production continuity, reduces the possibility of accidental slurry spillage, and provides a safe working environment.

[0153] The rectangular plate design of the buffer partition 6 and its direct connection with the connecting wall 104, as well as the design logic of the first side wall 102 and the second side wall 103 forming an equal and obtuse angle with the connecting wall 104, work together to improve the fluid handling capacity of the equipment, reduce energy consumption and disorder fluctuations in the slurry flow, improve the molding quality of pulp molded products, optimize production efficiency, and simplify maintenance and cleaning processes.

[0154] Furthermore, this application also provides a slurry skimming device, which includes a slurry skimming tank, wherein the slurry skimming tank is the aforementioned slurry skimming tank.

[0155] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0156] During use, the pulp enters the flow pipe 5 through the inlet pipe 2 and then enters the pulp collection tank body 1 through the overflow port 501 on the flow pipe 5. The pulp collection mold and the suction pipe 4 are connected by a steel wire hose. Then, the pulp in the pulp collection tank body 1 is vacuumed through the suction pipe 4 so that the pulp fibers in the pulp form a preliminary wet blank in the pulp collection mold under the action of vacuum. During the pulp collection process, when the liquid level of the pulp is higher than the height of the buffer baffle 6, it will enter the overflow space from the pulp collection space and flow out through the overflow pipe 7. The height of the first side wall 102 is higher than the height of the buffer baffle 6. At the same time, an air blowing pipe is also provided on the first side wall 102 for blowing air during pulp deposition to make the pulp more uniform. After the pulp collection is completed, the pulp can be discharged through the discharge port 3.

[0157] As the core of the entire system, the pulp collection tank body 1 ensures that the pulp is processed in a closed and optimized environment, improving the equipment's sealing performance and structural stability. The one-piece molded pulp collection tank body 1 and the overflow pipe 7 directly connect to reduce the risk of pulp leakage at the connection between the pulp collection tank body 1 and the pipe, while ensuring high efficiency in pulp circulation and continuity in the pulp processing process, thereby improving the production efficiency and quality of pulp molding products.

[0158] The slurry inlet pipe 2 is the entrance for the slurry to enter the slurry tank body 1. It ensures that the slurry can enter the flow pipe 5 at a stable and controllable speed. This design is conducive to the uniform distribution of slurry in the slurry tank body 1, avoids uneven concentration and slurry waste caused by local accumulation of slurry, and improves the utilization efficiency of slurry.

[0159] The overflow port 501 on the flow pipe 5 is connected to the inside of the pulp tank body 1, which can ensure that the pulp can be smoothly transferred into the pulp tank body 1. This design reduces the impact of the pulp when entering the pulp tank body 1, reduces the generation of air bubbles, ensures the fluidity of the pulp in the pulp tank body 1, is conducive to the uniform distribution of pulp fibers, and improves the uniformity and quality of pulp molded products in the molding process.

[0160] The suction pipe 4 is connected to the pulp mold via a steel wire hose. It uses vacuum force to promote the formation of a preliminary wet preform on the mold. This design effectively separates the fiber and water in the pulp, improves the deposition efficiency of the pulp fiber, and at the same time, due to the optimized layout of the suction pipe 4, the unevenness of the fiber during the deposition process is reduced, thus improving the forming quality of the wet preform.

[0161] The integral molding connection design of the overflow pipe 7 and the slurry tank body 1 ensures that the slurry can be discharged quickly and smoothly when it exceeds the height of the buffer baffle 6. This design not only maintains the uniform liquid level of the slurry in the slurry tank body 1 and avoids slurry overflow, but also promotes the circulation of slurry, improves the slurry processing efficiency, and reduces slurry waste in the production process.

[0162] The buffer baffle 6, as part of the internal structure, is designed to divide the slurry scooping space and the overflow space. When the slurry level rises above the buffer baffle 6, the excess slurry will automatically overflow into the overflow space and be discharged through the overflow pipe 7. This design optimizes the distribution and circulation of slurry in the slurry scooping tank body 1, improves the stability and safety of equipment operation, and reduces energy consumption and cost in slurry treatment.

[0163] The first sidewall 102 is higher than the buffer partition 6. Its design provides a higher overflow threshold for the pulp. This design avoids premature overflow of the pulp and reduces unnecessary interruptions in pulp processing. At the same time, the air blowing pipe set on the first sidewall 102 can promote the uniform distribution of the pulp, improve the uniformity of pulp fiber deposition in the tank, and optimize the forming effect of wet preform.

[0164] After the slurry skimming process is completed, the slurry discharge port 3 can effectively remove the remaining slurry in the slurry skimming tank body 1. This design simplifies the slurry recovery and cleaning work in the production process, reduces equipment downtime, and improves production efficiency. In addition, the reasonable layout of the slurry discharge port 3 helps to maintain the cleanliness of the tank body and extends the service life of the equipment.

[0165] Through the above design, including the comprehensive application of the pulp inlet pipe 2, flow pipe 5, suction pipe 4, overflow pipe 7, buffer baffle 6, first side wall 102 and discharge port 3, this series of optimized designs work together to improve the molding quality of pulp molded products, optimize pulp processing efficiency, reduce energy consumption and pulp waste in the production process, simplify equipment maintenance and cleaning procedures, and demonstrate the significant effect of the design in improving equipment performance, reducing production costs and improving product quality.
