Description

Technical Field

[0001] This utility model relates to the field of buffer tank technology, specifically to a buffer structure and a buffer tank. Background Technology

[0002] In industries such as chemical engineering, buffer tanks or similar containers are commonly used for the storage, mixing, or buffered transport of materials. However, when materials (especially those with high-speed flow or high impact) enter the container, they can easily cause strong impacts on the inner wall and internal structure of the container, making it difficult to effectively cope with the complex and variable pressure fluctuations inside the thickener. When the feed flow rate changes significantly, it is also difficult to maintain stable system pressure.

[0003] Existing buffer structures typically employ fixed buffer plates or simple inclined baffles to mitigate material impact. For example, CN205199012U discloses a multi-partition vacuum buffer tank, including a tank body. The top of the tank body is provided with a vacuum inlet, a vacuum outlet, and a vent, while the bottom of the tank body is provided with a discharge port. A first baffle and a second baffle are respectively provided at the vacuum inlet and the vacuum outlet. The buffer plate at the vacuum inlet can buffer the incoming material.

[0004] However, when faced with large flow rates or high-impact materials, the baffle plate has limited buffering effect and is prone to structural deformation or damage due to long-term impact. Utility Model Content

[0005] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose a buffer structure and buffer tank to solve the technical problems of limited buffering effect of existing buffer devices and the easy deformation or damage of buffer structures due to long-term impact.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution: In a first aspect, this utility model provides a buffer structure disposed inside a container, comprising: a plurality of buffer plates and a plurality of rotating buffer structures. The plurality of buffer plates are arranged sequentially from the inlet to the outlet of the container, wherein the buffer plates near the inlet are horizontally arranged, and the remaining buffer plates are arranged in an alternating inclined manner; the plurality of rotating buffer structures are arranged sequentially along the circumference of the buffer plates near the inlet, and the rotating buffer structures are connected to the buffer plates and configured to be rotatably connected to the container, and can buffer the rotational impact force generated by the material on the buffer plates through the rotating buffer structures.

[0007] In some embodiments, each of the buffer plates is provided with a material hole, and the diameter of the material holes of the plurality of buffer plates decreases sequentially from the inlet to the outlet.

[0008] In some embodiments, the plurality of buffer plates each include a first partition, a second partition, and a third partition, wherein the first partition, the second partition, and the third partition are arranged sequentially from the inlet to the outlet of the container.

[0009] In some embodiments, the inclination angles of the second and third partitions are 10° and 15°, respectively.

[0010] In some embodiments, the rotational buffer structure includes a rotational damper, which is fixedly installed on the inner wall of the container, and its piston rod is connected to the first partition via a universal joint.

[0011] In some embodiments, four rotational buffer structures are provided, which are evenly distributed along the circumference of the first partition.

[0012] In some embodiments, a protective cover is provided on the first partition, the protective cover surrounding the outside of the first partition to block the first partition and the rotation buffer structure.

[0013] In some embodiments, the buffer structure further includes a second buffer structure, the second buffer structure including a mounting member, a piston damper and a flexible tube, the mounting member being disposed at the bottom of the second partition, the piston damper being disposed between the second partition and the mounting member, and the flexible tube surrounding the piston damper, with its two ends respectively connected to the second partition and the mounting member.

[0014] In some embodiments, the buffer structure further includes a silicone damping layer, and a partition is provided in the middle of the third partition, with the silicone damping layer disposed within the partition.

[0015] Secondly, this utility model also provides a buffer tank, including the buffer structure described in any one of the above.

[0016] Compared with the prior art, the buffer structure and buffer tank provided by this utility model, through the setting of several buffer plates and several rotating buffer structures, the buffer plates near the feed inlet are horizontally set, which can initially reduce the speed and impact force of the material. At the same time, through the rotating buffer structure and the container being rotatably connected, the buffer plates can generate a certain rotation when subjected to asymmetrical impacts from the material, thereby further absorbing and dispersing the impact force and avoiding structural deformation or damage. The remaining buffer plates are arranged in an alternating inclined manner, which can further disperse and guide the material flow, so that the pressure wave can be effectively attenuated and achieve the purpose of stabilizing the pressure.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] To address the technical problems of limited buffering effect of buffer devices and the susceptibility of buffer structures to deformation or damage due to long-term impact, this utility model provides a buffer structure and buffer tank that can effectively reduce the impact of materials on the inner wall and internal structure of the container, thereby improving the buffering effect.

[0021] It should be noted that the buffer structure described in this utility model is used in, but not limited to, buffer tanks, etc. For ease of explanation, this utility model only uses the application of the buffer structure in a buffer tank as an example for explanation. The principle of the buffer structure applied to other types of equipment is essentially the same as that applied to a buffer tank, and will not be described in detail here.

[0022] Please see Figure 1In a first aspect, embodiments of this application provide a buffer structure disposed inside a buffer tank 5, comprising: a plurality of buffer plates 1 and a plurality of rotating buffer structures 2. The plurality of buffer plates 1 are arranged sequentially along the feed inlet 51 to the discharge outlet 52 of the buffer tank 5, wherein the buffer plates 1 near the feed inlet 51 are arranged horizontally, and the remaining buffer plates 1 are arranged in an alternating inclined manner; the plurality of rotating buffer structures 2 are arranged sequentially along the circumference of the buffer plates 1 near the feed inlet 51, and the rotating buffer structures 2 are rotatably connected to the buffer plates 1 and disposed in a rotatably connected manner with the buffer tank 5, and can buffer the rotational impact force generated by the material on the buffer plates 1 through the rotating buffer structures 2.

[0023] In this device, when the material enters through the feed inlet 51, it can directly withstand the initial impact through the horizontal buffer plate 1 near the feed inlet 51, and disperse the force through the rotating buffer structure 2. The rotating buffer structure 2 connects the buffer plate 1 and the buffer tank 5, so that the buffer plate 1 can rotate slightly and absorb energy when it is impacted by the material, which significantly reduces the direct impact on the inner wall of the buffer tank 5. The remaining inclined buffer plates 1 further slow down the flow rate. The overall structure is wear-resistant and has a long service life.

[0024] In this system, several buffer plates 1 are installed vertically in sequence inside the buffer tank 5, while the upper baffle is installed horizontally. However, the fluid impact is not perpendicular to the plate surface. When the thickener feed flow rate changes abruptly, the fluid often impacts the baffle in the form of an oblique jet or tangential vortex. This asymmetrical fluid impact causes the baffle to rotate around its central axis. The connection between the baffle and the tank body is prone to fatigue cracking due to periodic deflection. The rotating buffer structure 2 absorbs the circumferential torsional vibration energy of the baffle, rather than simply buffering vertical displacement, thus significantly improving the buffering effect.

[0025] Please see Figure 2 , Figure 5 and Figure 6 Preferably, in this embodiment, the buffer plate 1 is provided with material holes 14 for material flow. The diameter of the material holes 14 of the multiple buffer plates 1 decreases sequentially from the inlet 51 to the outlet 52, which can better control the flow rate and speed of the material and improve the buffering effect. Of course, in other embodiments, a gap can also be provided between the buffer plate 1 and the inner wall of the buffer tank 5 to ensure that the material can pass through smoothly.

[0026] In some possible embodiments, the material orifice 14 may also be a tapered flare.

[0027] Please see Figures 1 to 5In one embodiment, several buffer plates 1 include a first partition 11, a second partition 12, and a third partition 13, which are sequentially arranged from the inlet 51 to the outlet 52 of the buffer tank 5. The first partition 11 is positioned near the inlet 51, 50 cm from the top of the tank. The second partition 12 and the third partition 13 are arranged in a staggered, inclined manner below the first partition 11. The highest point of the second partition 12 is 30 cm from the first partition 11, and the highest point of the third partition 13 is 20 cm from the bottom of the second partition 12. The material holes 14 of the first partition 11 have a diameter of 20 mm, the second partition 12 have a diameter of 15 mm, and the third partition 13 has a diameter of 10 mm. The material holes 14 of adjacent partitions are staggered. Furthermore, the second partition 12 is inclined downwards at a 10° angle, and the third partition 13 is inclined downwards at a 15° angle. This design allows the material to gradually slow down and be evenly distributed as it flows through each buffer plate 1. At the same time, by precisely controlling the diameter of the material holes 14 on each buffer plate 1, the flow rate of the material can be more effectively adjusted, ensuring the stable flow of the material in the buffer tank 5.

[0028] Please see Figure 1 and Figure 6 In some possible embodiments, the bottom edges of the second baffle 12 and the third baffle 13 are left with a 20mm gap from the tank wall to prevent material accumulation. A cross-shaped reinforcing rib 17 is welded to the back of each buffer plate 1 to improve the structural strength of the buffer plate 1.

[0029] In other possible embodiments, the number of buffer plates 1 and the aperture of the material holes 14 are not limited to this and can be adjusted according to specific application scenarios and requirements.

[0030] Please see Figures 1 to 3 In order to improve the buffering effect of the first partition 11, in some possible embodiments, four rotating buffer structures 2 are provided, which are evenly distributed along the circumference of the first partition 11 and the first partition 11 are kept at a 90° interval. This can better absorb the impact force from different directions and ensure that the first partition 11 can rotate stably and disperse energy when it is impacted by materials.

[0031] Please see Figures 1 to 3 In some possible embodiments, the rotating buffer structure 2 includes a rotating damper 21, which absorbs kinetic energy through hydraulic oil compression and spring deformation. The rotating damper 21 is fixedly installed on the inner wall of the buffer tank 5. Its piston rod is connected to the first partition 11 through a universal joint. A connecting plate 16 with a U-shaped groove is provided at the connection position between the first partition 11 and the universal joint. One end of the piston rod can slide in the U-shaped groove to allow the first partition 11 to rotate slightly around the central axis when it is impacted by material.

[0032] To prevent material from splashing into the rotating buffer structure 2 after contacting the first partition 11, please refer to [link / reference needed]. Figure 1 and 2 In some possible embodiments, a protective cover 15 is provided on the top surface of the first partition 11. The protective cover 15 surrounds the outside of the first partition 11, and its sidewalls are inclined to form a flared structure. Its top surface also has an outwardly extending edge, which is above the rotary damper 21. The piston rod of the rotary damper 21 is connected to the sidewall of the protective cover 15. By setting the protective cover 15 to block between the first partition 11 and the rotary buffer structure 2, it is possible to effectively prevent materials from splashing into the rotary damper 21 and other rotating components when impacting the first partition 11 at high speed, thus avoiding mechanical failure and performance degradation caused by material entry.

[0033] To effectively cushion the impact of materials on the second partition 12, please refer to... Figure 1 and Figure 4 In some possible embodiments, the buffer structure further includes a second buffer structure 3, which includes a mounting component 31, a piston damper 32, and a flexible tube 33. The mounting component 31 adopts a frame structure and is located at the bottom of the second partition 12 and is fixedly connected to the buffer tank 5. The middle opening of the frame structure corresponds to multiple material holes 14 of the second partition 12. The material discharged through the material holes 14 will fall directly through the middle opening of the frame structure and will not impact the mounting component 31. A piston damper 32 is disposed between the second partition 12 and the mounting member 31. A flexible tube 33 surrounds the outside of the piston damper 32, with its two ends connected to the second partition 12 and the mounting member 31, respectively. This structure connects the second partition 12 and the mounting member 31 through the flexible tube 33. The piston damper 32 is only fixed to the mounting member 31, with its top contacting the second partition 12. One end of the second partition 12 is connected to the buffer tank 5 through a rotating or flexible structure, and the piston damper 32 is located below the other end of the second partition 12. When material impacts the second partition 12, the piston damper 32 can absorb kinetic energy through hydraulic oil compression and spring deformation, effectively reducing the vibration and impact of the second partition 12. At the same time, the design of the flexible tube 33 allows the second partition 12 to have a certain deformation space when subjected to material impact, further enhancing the buffering effect. In addition, the flexible tube 33 can also isolate the material from direct contact with the piston damper 32, avoiding the degradation of damper performance due to material erosion.

[0034] Because the flow rate and impact force of the material are buffered by the first baffle 11 and the second baffle 12, the speed and impact force of the material are greatly reduced when it reaches the third baffle 13. For further optimization of the buffering effect of the third baffle 13, please refer to [link to relevant documentation]. Figure 1 and Figure 5In some possible embodiments, a partition is provided in the middle of the third partition 13, and a silicone damping layer 4 is provided within the partition. The material hole 14 penetrates the silicone damping layer 4. The silicone damping layer 4 is made of highly elastic silicone material, which has good compressibility and resilience, as well as excellent elasticity and wear resistance. When material impacts the third partition 13, the silicone damping layer 4 can absorb energy through its own deformation, effectively reducing the impact force and further protecting the inner wall of the buffer tank 5. At the same time, the silicone material also has good chemical corrosion resistance, which can adapt to the buffering needs of different materials, improving the applicability and durability of the buffer structure.

[0035] Please see Figures 1 to 7 Secondly, this application also provides a buffer tank, including the buffer structure of any of the above embodiments. In practical applications, material enters the buffer tank 5 from the inlet 51 and first contacts the horizontally arranged first baffle 11. This design effectively withstands the initial impact of the material and disperses the impact force by rotating the buffer structure 2, avoiding direct impact on the inner wall of the buffer tank 5. Subsequently, the material flows through the staggered inclined second baffle 12 and third baffle 13, further slowing down the flow rate of the material.

[0036] This invention utilizes several buffer plates 1 and several rotating buffer structures 2. The buffer plates 1 near the feed inlet 51 are horizontally positioned, which can initially reduce the speed and impact force of the material. At the same time, the rotating buffer structures 2 are rotatably connected to the buffer tank 5, which allows the buffer plates 1 to rotate to a certain extent when subjected to asymmetrical impacts from the material, thereby further absorbing and dispersing the impact force and preventing structural deformation or damage. The remaining buffer plates 1 are arranged in an alternating inclined manner, which can further disperse and guide the material flow, so that the pressure wave can be effectively attenuated and the purpose of stabilizing the pressure can be achieved.
