Description

Technical Field

[0001] This utility model relates to the field of air compression technology, specifically to an improved compressed air filtration and pressure stabilization system. Background Technology

[0002] A compressed air filtration and stabilization system is a device system used to filter and stabilize compressed air to provide a clean and stable air source. It provides clean compressed air that meets hygiene standards in pharmaceutical production, medical device manufacturing, and hospital air supply, meeting the needs of production and medical processes.

[0003] However, untreated compressed air usually contains impurities such as moisture, oil droplets, and dust particles. These impurities can damage equipment that uses compressed air, such as causing wear and tear, clogging pipes, and affecting the normal operation and service life of the equipment. At the same time, unstable compressed air pressure can make it difficult to control the production process stably, reducing product quality and production efficiency.

[0004] Existing compressed air filtration and stabilization systems use compressed air that has undergone purification processes such as cold drying, oil removal, water removal, removal of solid dust particles, and sterilization filtration before being used in production. However, the instantaneous usage at each point of use is unstable, leading to unstable air pressure and severe wear on the air generation equipment. Therefore, we have proposed an improved compressed air filtration and stabilization system that can effectively solve the above problems. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: an improved compressed air filtration and pressure stabilization system, comprising an air compressor, the output end of which is connected to an air storage tank 1 via a pipeline, the discharge port of the air storage tank 1 being connected to two refrigerated dryers via a pipeline, and the output end of each refrigerated dryer being connected to three sequentially connected first filter devices via a pipeline equipped with a No. 50 valve, and the output end of the last stage of the first filter device being connected to an adsorption tower via a pipeline equipped with a No. 50 valve, the output end of the adsorption tower being connected to two sequentially connected second filter devices via a pipeline, and the output end of the last stage of the second filter device being connected to an air storage tank 2 via a pipeline, the output end of the last stage of the first filter device also being connected to the input end of the first stage of the second filter device via a pipeline equipped with a No. 50 valve, the discharge port of the air storage tank 2 being connected to the input end of the filter via an air supply pipeline, and the output end of the filter being connected to the input end of the production equipment via a pipeline.

[0007] Preferably, the volume of gas storage tank 1 and gas storage tank 2 is 1m³, the volume of the two refrigerated dryers is 11m³, the volume of the three first filter devices is 11m³, and the volume of the two second filter devices is 11m³.

[0008] Preferably, flanges are welded to the opposite ends of the two gas pipelines, and bolts are connected at equal angles inside the flange on the left side. Limiting rods are fixed to the sides of the four bolts, and a drive gear is fixed to the outer side of the middle of the four bolts. A drive gear ring is fitted on the outer wall of the flange on the left side, and threaded holes are opened at equal angles inside the flange on the right side. A sealing gasket is provided on the side of the flange.

[0009] Preferably, the four drive gears are rotatably connected inside the flange, and the drive gears are threadedly connected to the bolts. The bolts are slidably disposed inside the flange via a limiting rod. The drive gear ring is rotatably connected to the flange, and the four drive gears of the drive gear ring are meshed together. The positions of the bolts and the threaded holes correspond one-to-one.

[0010] Preferably, a movable block is slidably connected to the top of the flange on the left side, a limit hole is opened at an equal angle on the left side of the drive gear ring, and a return spring is installed between the lower left side of the movable block and the inner wall of the flange.

[0011] Preferably, the movable block is arranged in an inverted "L" shape, and the movable block and the limiting hole are connected by an insertion.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This improved compressed air filtration and pressure stabilization system adopts a novel structural design, the specific details of which are as follows:

[0013] (1) In order to improve the current situation of unstable compressed air supply, technical modifications were made to the original air supply system. After the compressed air undergoes purification processes such as cold drying, oil removal, water removal, removal of solid dust particles and sterilization filtration, a compressed air storage tank was added and the output air pressure of the compressed air pipeline was adjusted and optimized to reduce the water content in the compressed air and ensure the quality and stability of the compressed air. Furthermore, a No. 2 air storage tank for the compressed air system delivery pipeline was added to the original compressed air control supply system pipeline, and the diameter of the air supply pipeline was adjusted and optimized. The diameter of the compressed air pipeline for the gas generation, cooling, filtration, adsorption and filtration sections is ≥ the output diameter of the No. 2 air storage tank, which solves the problem of insufficient supply air velocity, improves the pressure stability and quality in the continuous compressed air supply system, and reduces the wear on the gas generation equipment.

[0014] (2) When encountering high temperature weather, both refrigerated dryers are used at the same time to reduce the moisture content of compressed air and protect downstream equipment; furthermore, all pipes and valves are of the same diameter to prevent multiple compressed air interception when using large flow rates, and a No. 2 air storage tank is added after the final filter to provide a compensation buffer when the production process uses a large flow rate of air, so as to protect the production equipment from low pressure alarms and chain reactions such as equipment shutdown protection and unqualified production quality, which greatly reduces the occurrence of production equipment failures. In addition, by switching the closing and opening of valves No. 3 and No. 4, it is more intuitive to judge whether the adsorption tower and multi-stage filter are blocked and cannot meet the production air demand based on the pressure difference between the two air storage tanks.

[0015] (3) Connect the two gas pipelines together through the flanges and rotate the drive gear ring so that the drive gear ring drives the four meshing driven gears to rotate simultaneously, thereby driving the four bolts to move simultaneously and screw into the corresponding threaded holes, thus quickly completing the connection between the gas pipelines and improving work efficiency; furthermore, after the drive gear ring has rotated, release the movable block so that it is reset under the elastic force of the return spring and inserted into the corresponding limit hole, which can limit the drive gear ring and prevent it from deflecting during use; further still, the sealing gasket set between the two flanges can improve the sealing of the gas pipeline connection position and prevent compressed air leakage.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-7 The present invention provides the following technical solution: an improved compressed air filtration and pressure stabilization system;

[0026] Example 1: To address the problem in existing technologies where compressed air undergoes purification processes such as cold drying, oil removal, water removal, solid dust particle removal, and sterilization filtration before being used in production, but the instantaneous consumption at various points of use is unstable, leading to unstable air pressure and severe wear on the air generation equipment, the following solution is disclosed. Please refer to the following for details. Figures 1-3 As shown, where Figure 2 The 11m³ filtration unit located between the two 11m³ refrigerated dryers 3 and the 11m³ adsorption tower 5 is Figure 1 The first filter device 4, at the same time Figure 2 The 11m³ filter unit located between the 11m³ adsorption tower 5 and the 2m³ gas storage tank 7 is Figure 1 The second filter device 6 in the middle, and Figure 2 The 1m³ gas storage tank No. 27 and the bacterial level filter No. 8 between each production equipment are... Figure 1The intermediate filter 8 includes an air compressor 1. The output end of the air compressor 1 is connected to an air storage tank 1 2 via a pipe. The discharge port of the air storage tank 1 2 is connected to two refrigerated dryers 3 via pipes. The output end of each refrigerated dryer 3 is connected to three sequentially connected first filter devices 4 via pipes equipped with valves 50 and 9. The output end of the last stage of the first filter device 4 is connected to an adsorption tower 5 via a pipe equipped with valves 50 and 9. The output end of the adsorption tower 5 is connected to two sequentially connected second filter devices 6 via pipes. The output end of the last stage of the second filter device 6 is connected to... The gas storage tank 2 is connected to the gas storage tank 7 via a pipeline. The output end of the first filter device 4 in the last stage is also connected to the input end of the second filter device 6 in the first stage via a pipeline equipped with valve 9. The discharge port of the gas storage tank 2 is connected to the input end of the filter 8 via the gas supply pipeline 10, and the output end of the filter 8 is connected to the input end of the production equipment via a pipeline. The volume of the gas storage tank 1 and the gas storage tank 2 is 1m³, the volume of the two refrigerated dryers 3 is 11m³, the volume of the three first filter devices 4 is 11m³, and the volume of the two second filter devices 6 is 11m³.

[0027] Air compressor 1 is started to generate compressed air. The compressed air enters air storage tank 1 (2) for initial storage and buffering. Then, refrigerated dryer 3 is turned on to cool and dry the compressed air from air storage tank 1 (2), removing moisture. The compressed air after being processed by refrigerated dryer 3 then enters three first filtration devices 4. The filtered compressed air then enters adsorption tower 5, where it is further purified by adsorbent to remove residual impurities and odors. The purified compressed air then enters two second filtration devices 6 for further filtration. The second-filtered compressed air then enters air storage tank 2 (7). A pressure sensor monitors the pressure inside the tank in real time. When the pressure exceeds the set upper limit, the pressure regulating valve automatically opens to release some compressed air. When the pressure falls below the set lower limit, the pressure regulating valve automatically closes to prevent excessive loss of compressed air, thus achieving pressure stabilization. Finally, the pressure-stabilized compressed air passes through filter 8 (this filter... After sterilization treatment (at the bacterial level) by device 8, the compressed air is delivered to the production equipment for use, thereby solving the problem of insufficient air supply speed, improving the pressure stability and quality of the continuous compressed air supply system, reducing wear on the gas generating equipment, and then, in the event of high temperature weather, two refrigerated dryers 3 are activated simultaneously to reduce the moisture content of the compressed air and protect downstream equipment. In addition, all pipes and valves are of uniform diameter to prevent multiple compressed air interceptions during high-flow usage. Furthermore, the addition of storage tank 2 7 after the second filter device 6 provides a compensation buffer during instantaneous high-flow air usage, protecting the production equipment from low-pressure alarms and chain reactions such as equipment shutdown protection and substandard production quality, greatly reducing the occurrence of production equipment failures. By switching the opening and closing of valves 3 and 4, it is possible to more intuitively judge whether the adsorption tower 5 and multi-stage filter 8 are blocked and unable to meet the production air demand based on the pressure difference between the two storage tanks.

[0028] Example 2: Unlike Example 1, this example uses a forward-rotating drive gear ring 18 to quickly connect two gas pipelines 10, improving work efficiency. See details... Figures 4-7 As shown, flanges 11 are welded to the opposite ends of the two gas pipelines 10. Bolts 13 are connected at equal angles inside the flange 11 on the left side. Limiting rods 17 are fixed to the sides of the four bolts 13. Drive gears 16 are fixed to the outer side of the middle of the four bolts 13. A drive gear ring 18 is fitted on the outer wall of the left flange 11. Threaded holes are opened at equal angles inside the flange 11 on the right side. The four drive gears 16 are rotatably connected inside the flange 11. The drive gears 16 and the bolts 13 are threadedly connected. The bolts 13 are slidably set inside the flange 11 through the limiting rods 17. The drive gear ring 18 is rotatably connected to the flange 11. The four drive gears 16 of the drive gear ring 18 are meshed with each other. The positions of the bolts 13 and the threaded holes correspond one-to-one.

[0029] The workers connect the two gas pipelines 10 together via flange 11 and pull the movable block 12 to the left to separate it from the limiting hole, releasing the limiting of the drive gear ring 18. Then, they drive the gear ring 18 forward, causing it to drive the four meshing drive gears 16 to rotate simultaneously. This, in turn, causes the four bolts 13 to move simultaneously and screw into the corresponding threaded holes on another flange 11, thereby locking the two gas pipelines 10. This quickly completes the installation between the two gas pipelines 10 and improves work efficiency.

[0030] Example 3: Unlike Example 2, this example utilizes a sealing gasket 14 to improve the sealing at the connection point of the two air supply pipes 10, preventing compressed air leakage. See details... Figure 4 and Figure 5 As shown, a sealing gasket 14 is provided on the side of the flange 11, and a movable block 12 is slidably connected to the top of the left flange 11. A limit hole is opened at an equal angle on the left side of the drive gear ring 18. A return spring 15 is installed between the lower left side of the movable block 12 and the inner wall of the flange 11. The movable block 12 is set in an inverted "L" shape, and the movable block 12 and the limit hole are connected by an insertion.

[0031] When the two flanges 11 are joined together, the sealing gasket 14 on one flange 11 fits into the sealing groove on the other flange 11, thereby improving the sealing of the connection of the gas pipeline 10 and preventing compressed air leakage.
