Description

Technical Field

[0001] This utility model relates to the field of plate and frame application technology, and in particular to a buffer device for purging plate and frame with compressed air. Background Technology

[0002] Compressed air purging is a crucial process for cleaning and maintaining plate and frame structures. Currently, the industry commonly employs direct purging, introducing compressed air into the plate and frame through simple pipes for cleaning. While this traditional method is simple to operate, it lacks an effective energy buffering mechanism, revealing significant technical shortcomings in actual operation. When high-pressure gas is released instantaneously, its immense kinetic energy cannot be effectively channeled, leading not only to severe mechanical vibrations in the piping system but also to the disordered discharge of the gas-liquid mixture. These problems highlight the deficiencies in current gas energy management, particularly the lack of a systematic solution for the kinetic energy conversion and buffering during high-pressure gas release. Although some equipment attempts to alleviate these problems by adding silencers or expanding pipes, none have fundamentally achieved a staged and stable release of gas energy, severely impacting the operational stability and service life of the equipment.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be particularly noted that the following embodiments are only for illustrating the present invention and do not limit the scope of the present invention. Similarly, the following embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0027] Please see Figure 1 This embodiment provides a buffer device for purging a plate frame with compressed air, including: a buffer tank 1, an energy release tank 2, an air inlet pipe, a first air outlet pipe 3, and a second air outlet pipe 4. The top of the buffer tank 1 is provided with a first air outlet 11 and a second air outlet 12, which are arranged opposite to each other. The energy release tank 2 is located at the first air outlet 11 and is connected to the buffer tank 1 through the first air outlet 11. The side wall of the energy release tank 2 is provided with an air inlet 21, and the top of the energy release tank 2 is provided with a third air outlet 13. The first air outlet 11 and the third air outlet 13 are coaxial. The air inlet pipe is connected to the air inlet 21 and is used to introduce compressed air at a first pressure. The first air outlet pipe 3 is connected to the third air outlet 13 and is used to output compressed air at a second pressure, which is less than the first pressure. The second air outlet pipe 4 is connected to the second air outlet 12 and is used to output compressed air at a second pressure.

[0028] In this embodiment, the buffer tank 1 is a sealed container with a large internal space, used to provide a gas expansion buffer area. A first outlet 11 and a second outlet 12 symmetrically arranged on its top are used to evenly discharge gas. The energy release tank 2 is an independent cavity connected to the first outlet 11 of the buffer tank 1. An inlet 21 on its side wall is used to receive high-pressure gas, and a third outlet 13 on its upper part is coaxially arranged with the first outlet 11 to ensure stable airflow direction. The inlet pipe is preferably made of pressure-resistant metal tubing to transport high-pressure compressed air to the energy release tank 2. The first outlet pipe 3 and the second outlet pipe 4 are respectively connected to the third outlet 13 and the second outlet 12 to output the depressurized gas; their pipe diameter design must ensure a smooth airflow output.

[0029] The working principle of this device can be understood as follows: high-pressure compressed air enters the energy release tank 2 through the inlet pipe. After the initial pressure reduction is completed in the energy release tank 2, it enters the buffer tank 1 through the first outlet 11 for further diffusion and buffering. Finally, low-pressure gas is stably output through the first outlet pipe 3 and the second outlet pipe 4.

[0030] This embodiment achieves two-stage energy release of compressed air through the synergistic effect of buffer tank 1 and energy release tank 2. The high-pressure gas first undergoes initial depressurization in energy release tank 2, then enters buffer tank 1 for full diffusion, converting kinetic energy into potential energy and effectively reducing airflow impact. Symmetrically arranged outlets evenly discharge gas, avoiding vibration caused by unilateral airflow accumulation. This embodiment not only alleviates the problem of disordered discharge of gas-liquid mixtures in the pipeline but also significantly reduces the impact of airflow pulsation on the equipment, thereby improving the stability and reliability of the system operation.

[0031] In some embodiments, the first vent pipe 3 extends downward through the third vent 13 to a predetermined length inside the energy release tank 2.

[0032] In this embodiment, the first gas outlet pipe 3 extends downward through the third gas outlet 13 to a certain depth inside the energy release tank 2, so that when the high-pressure gas flows in the energy release tank 2, it first contacts the extended pipe section to form a preliminary buffer, and then enters the buffer tank 1 for further diffusion.

[0033] This embodiment extends the airflow path, allowing for more complete absorption and conversion of gas kinetic energy, thereby further reducing the pulsation and impact of the output gas and improving the stability of system operation. By optimizing the airflow path, this embodiment enhances the buffering effect of the device, resulting in more uniform and stable compressed air discharge.

[0034] In some embodiments, the air inlet 21 is located above the side wall of the energy release tank 2 and above the end of the first air outlet pipe 3.

[0035] In this embodiment, by positioning the air inlet 21 above the side wall of the energy release tank 2 and higher than the end of the first outlet pipe 3, the high-pressure gas, upon entering, first impacts downwards into the bottom space of the energy release tank 2, forming a forced vortex deceleration. This embodiment utilizes the gas's own weight and the change in flow direction to achieve initial kinetic energy dissipation. Subsequently, the airflow is smoothly output through the first outlet pipe 3, effectively reducing gas impact noise and improving energy release efficiency. This arrangement optimizes airflow organization, making the compressed air depressurization process more thorough and stable.

[0036] In some embodiments, the intake pipe has a first cross-sectional area, and the buffer tank 1 has a second cross-sectional area, which is a multiple of the first cross-sectional area.

[0037] In this embodiment, by setting the cross-sectional area of ​​the buffer tank 1 to a specific multiple of the cross-sectional area of ​​the air inlet pipe, when high-pressure gas enters the buffer tank 1 from the air inlet pipe, the gas flow rate decreases significantly due to the sudden expansion of the flow cross-sectional area, and the kinetic energy is converted into pressure energy.

[0038] This embodiment utilizes the expansion effect caused by the abrupt change in cross-sectional area to create a stable vortex diffusion of gas within the buffer tank 1, thereby effectively absorbing airflow pulsations and achieving smooth pressure reduction. This embodiment significantly improves the buffering performance of the device, ensuring a more stable and uniform output airflow.

[0039] In some embodiments, the second cross-sectional area is 200 times the first cross-sectional area.

[0040] In this embodiment, by precisely setting the cross-sectional area of ​​the buffer tank 1 to 200 times that of the inlet pipe, when high-pressure gas enters the buffer tank 1 from the narrow inlet pipe, the flow area suddenly expands, the gas velocity drops sharply, and sufficient diffusion occurs. This significant change in cross-sectional area allows for efficient dissipation of gas kinetic energy, creating a stable pressure field within the buffer tank 1, thereby significantly reducing airflow pulsation and noise. This embodiment, by optimizing the cross-sectional area ratio, makes the gas expansion process more complete, greatly improving the pressure stabilization and noise reduction effects of the device, and ensuring a smooth and uniform output airflow.

[0041] In some embodiments, the buffer device further includes an elastic support member disposed at the connection between the air intake pipe and the energy release tank 2.

[0042] In this embodiment, an elastic support is installed at the connection between the air intake pipe and the energy release tank 2. The vibration generated when high-pressure gas flows through the pipe is absorbed and buffered by the elastic support. This embodiment utilizes the deformation characteristics of elastic materials to effectively isolate the transmission of mechanical vibration between the air intake pipe and the energy release tank 2. This avoids stress concentration caused by rigid connections, reduces vibration noise, significantly improves the operational stability of the device, and extends the service life of key components.

[0043] In some embodiments, the elastic support is a bellows.

[0044] In this embodiment, by employing a bellows as an elastic support, when the intake pipeline vibrates due to airflow pulsation, the bellows, with its unique waveform structure, can flexibly deform along the axial and radial directions, effectively absorbing and buffering mechanical vibration. The corrugated peaks and troughs of the bellows can evenly distribute stress during deformation, avoiding localized stress concentration, while its continuous and smooth transition characteristics ensure smooth airflow. This embodiment achieves both efficient dissipation of vibration energy and maintenance of the pipeline system's sealing integrity, enabling the device to maintain stable vibration reduction and noise reduction performance during long-term operation.

[0045] In some embodiments, the inner wall of the connection between the energy release tank 2 and the buffer tank 1 is also provided with staggered guide plates.

[0046] In this embodiment, the guide plates at the connection between the energy release tank 2 and the buffer tank 1 are staggered plate-like structures used to guide the airflow direction. By altering the airflow path, the guide plates extend the flow path, causing turbulence to form during the transition between the tanks, thus promoting energy dissipation. Their staggered arrangement avoids direct airflow and achieves a more uniform velocity distribution.

[0047] This embodiment uses staggered guide vanes on the inner wall of the connection point. When the airflow passes through the tank connection point, the guide vanes force the airflow to change direction multiple times and form vortices, effectively dispersing the concentrated airflow area, so that the gas kinetic energy is attenuated in a stepwise manner, and finally achieving a stable pressure energy release. This significantly improves the uniformity of airflow organization and reduces energy loss and noise generation caused by local impacts.

[0048] In some embodiments, the end of the first air outlet pipe 3 is provided with a flared opening.

[0049] In this embodiment, by providing a flared structure at the end of the first exhaust pipe 3, the gradually expanding shape of the flared opening allows the airflow cross-section to expand smoothly when high-pressure gas is discharged from the pipe. This embodiment utilizes fluid dynamics principles to achieve the conversion of kinetic energy into static pressure energy by gradually reducing the airflow velocity, while avoiding eddies and energy loss caused by sudden expansion. This ensures a smooth airflow transition and effectively reduces exhaust noise.

[0050] In some embodiments, the first air outlet pipe 3 and the second air outlet pipe 4 are connected to the plate and frame filter press.

[0051] In this embodiment, by simultaneously connecting the first outlet pipe 3 and the second outlet pipe 4 to the plate and frame filter press, bidirectional airflow is achieved when gas enters the filter press through both pipes. Under the action of bidirectional airflow, the filter unit of the plate and frame filter press forms a more uniform media distribution, effectively improving filtration efficiency. The coordinated operation of the first outlet pipe 3 and the second outlet pipe 4 ensures both the gas throughput and avoids the problem of localized filter media blockage that may be caused by unilateral air intake.

[0052] By adopting the above technical solutions, this utility model differs from existing technologies and has the following beneficial effects: Through the two-stage energy release structure of the buffer tank 1 and the energy release tank 2, the high-pressure compressed air first undergoes preliminary depressurization in the energy release tank 2, and then enters the buffer tank 1 for full diffusion, converting kinetic energy into potential energy, effectively reducing airflow impact. The symmetrically arranged first air outlet 11 and second air outlet 12 discharge gas evenly, avoiding vibration problems caused by unilateral airflow accumulation. The first air outlet pipe 3 extends downward into the interior of the energy release tank 2, extending the airflow path and allowing the gas kinetic energy to be absorbed and converted more fully. The arrangement of the air inlet 21 above the side wall of the energy release tank 2 utilizes the gas's own weight and flow direction change to achieve preliminary kinetic energy dissipation. The cross-sectional area of ​​the buffer tank 1 is set to a large cross-sectional area change of 200 times that of the air inlet pipe, enabling efficient dissipation of gas kinetic energy. The use of a corrugated pipe as an elastic support effectively isolates vibration transmission and reduces noise. The staggered guide plates promote the formation of turbulent airflow, achieving stepped energy attenuation. The flared structure at the end of the first outlet pipe 3 ensures a smooth airflow transition and reduces exhaust noise. The bidirectional connection between the first outlet pipe 3 and the second outlet pipe 4 and the plate and frame filter ensures uniform distribution of the filter media. The synergistic effect of these components effectively mitigates the disordered discharge of gas-liquid mixtures, significantly reduces the impact of airflow pulsations on the equipment, improves the stability and reliability of the system operation, and simultaneously achieves good vibration reduction and noise reduction effects.
