Description

Technical Field

[0001] The utility model relates to the technical field of compressed air purification, in particular to an integrated drying tower with drying and filtering functions. Background Art

[0002] The existing compressed air purification system generally has the following pain points: poor drying stability, complex pipelines, and frequent inspection and maintenance. These problems not only increase the difficulty of system installation and maintenance, but may also cause the desiccant particles to be easily damaged and powdered under vibration and airflow impact, resulting in drying failure, reducing the efficiency and quality of compressed air during transmission.

[0003] Traditional systems usually require multi-stage filtration devices before and after the dryer to achieve functions such as water removal, oil removal and filtration. However, this multi-stage configuration not only increases the complexity and cost of the system, but may also cause additional pressure loss and energy consumption when the compressed air passes through each component. Utility Model Content

[0004] The purpose of the utility model is to provide an integrated drying tower with drying and filtering functions to solve the technical problems existing in the above-mentioned background technology.

[0005] To achieve the above purpose, the technical solution of the utility model is as follows:

[0006] An integrated drying tower with drying and filtering functions comprises: a drying cylinder, a tower cover, a polymer spherical filter plate, a solid drying core, a filling shell, an oil-water preliminary treatment layer and a hollow tube, wherein the tower cover is arranged at the left end of the drying cylinder, and the polymer spherical filter plate, the solid drying core and the oil-water preliminary treatment layer are arranged in sequence from left to right inside the drying cylinder, and the oil-water preliminary treatment layer is filled in the filling shell, and a hollow tube is arranged through the inside of the drying cylinder, and the left end of the hollow tube is fixedly connected to the tower cover, and the hollow tube passes through and seals the polymer spherical filter plate, the solid drying core and the filling shell in sequence from left to right, and a plurality of purified gas exhaust holes are evenly opened on the left outer wall of the hollow tube at a position between the polymer spherical filter plate and the tower cover, and the compressed air passes through the oil-water preliminary treatment layer, the solid drying core and the polymer spherical filter plate in sequence from right to left and enters the inner cavity of the hollow tube through the plurality of purified air exhaust holes and is then discharged.

[0007] Furthermore, an O-ring is provided at the connection between the tower cover and the drying cylinder.

[0008] Furthermore, the inner concave surface of the polymer spherical filter plate faces the tower cover.

[0009] Furthermore, the solid-state dry core is formed by hot pressing using molecular sieve material and an organic adhesive solvent.

[0010] Further, the preliminary oil-water treatment layer is a Raschig ring.

[0011] Further, a plurality of compressed air inlet holes distributed in a circumferential array are provided at the right end of the filling housing.

[0012] Further, a pressing plate is provided between the solid drying core and the preliminary oil-water treatment layer, and the solid drying core and the preliminary oil-water treatment layer are separated by the pressing plate. A plurality of primary filtration inlet holes for compressed air are provided on the pressing plate.

[0013] Further, it further includes: a snap ring, and the pressing plate is fixedly connected to the left side of the filling housing through the snap ring.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. Significantly improve the system efficiency:

[0016] By integrating multiple functional modules such as a mechanical oil-water separator, a solid drying core, and a polymer filter plate inside the drying tower, the present invention realizes one-stop treatment of compressed air. This integrated design eliminates the conversion loss and waiting time between components in the traditional system, and significantly improves the overall treatment efficiency. The efficient water removal, oil removal, filtration, and drying capabilities ensure high-quality output of compressed air and provide a stable and reliable air source for downstream processes.

[0017] 2. Greatly reduce the operating cost:

[0018] Traditional multi-stage filtration and drying systems, due to numerous components and complex pipelines, not only increase the initial investment cost, but also bring high maintenance costs and energy consumption. The present invention significantly reduces the operating cost by simplifying the system structure and reducing the connecting pipelines. In addition, the integrated design also reduces the failure points and maintenance workload, further reducing the long-term operating cost.

[0019] 3. Enhance the system stability and reliability:

[0020] The integrated design reduces the potential failure points in the system and improves the overall stability and reliability. The close integration between functional modules ensures the continuity and stability of the treatment process, and avoids system downtime or performance degradation caused by component failures. This is of great significance for ensuring the continuity of the production process and the stability of product quality.

[0021] 4. Optimize the space layout:

[0022] Traditional systems, due to their numerous components and complex pipelines, often occupy a large amount of space. In contrast, through an integrated design, this utility model integrates multiple functional modules into a single drying tower, greatly saving space resources. This is undoubtedly a huge advantage for industrial production environments with limited space. The optimized spatial layout not only improves space utilization but also contributes to enhancing the overall aesthetics and safety of the workshop.

[0023] 5. Promote green industrial development:

[0024] The popularization and application of this utility model contribute to promoting the greening and sustainable development of industrial production. By improving the purity and dryness of compressed air, it reduces energy consumption and emissions during the production process. At the same time, the simplified system structure and efficient processing flow also meet the requirements of modern industry for high efficiency, environmental protection, and intelligence. This helps to enhance the enterprise's environmental image and market competitiveness. Description of the Drawings

Detailed Description of the Preferred Embodiments

[0032] The following further elaborates on this utility model in conjunction with the drawings and embodiments.

[0033] See Figures 1 to 6 As shown, an integrated drying tower with a drying and filtering function includes: a drying cylinder 1, a tower cover 2, a polymer spherical filter plate 4, a solid drying core 5, a filling housing 7, an oil-water preliminary treatment layer 8, and a hollow tube 9. A tower cover 2 is provided at the left end of the drying cylinder 1. Inside the drying cylinder 1, a polymer spherical filter plate 4, a solid drying core 5, and an oil-water preliminary treatment layer 8 are arranged in sequence from left to right. The oil-water preliminary treatment layer 8 is filled inside the filling housing 7. A hollow tube 9 is arranged through the inside of the drying cylinder 1. The left end of the hollow tube 9 is fixedly connected to the tower cover 2. The hollow tube 9 sequentially penetrates and is hermetically connected to the polymer spherical filter plate 4, the solid drying core 5, and the filling housing 7 from left to right. A plurality of purified gas exhaust holes 901 are evenly opened at the position between the polymer spherical filter plate 4 and the tower cover 2 on the outer wall of the left side of the hollow tube 9. Compressed air sequentially passes through the oil-water preliminary treatment layer 8, the solid drying core 5, and the polymer spherical filter plate 4 from right to left and enters the inner cavity of the hollow tube 9 through a plurality of purified air exhaust holes 901 and then is discharged.

[0034] In this embodiment, an O-ring 3 is provided at the connection between the tower cover 2 and the drying cylinder 1. By providing the O-ring 3, the sealing performance of the connection between the tower cover 2 and the drying cylinder 1 can be ensured.

[0035] In this embodiment, the concave surface of the polymer spherical filter plate 4 faces the tower cover 2. The polymer spherical filter plate 4 serves as a fine filtering layer to further intercept impurities such as fine particles, dust, and residual oil mist, improving the air cleanliness; the spherical shape can ensure that the dried gas is output into the hollow tube 9 and flows out, reducing the air resistance.

[0036] In this embodiment, the solid drying core 5 is formed by hot pressing a molecular sieve material and an organic adhesive solvent, and can absorb and remove the residual moisture in the compressed air. The core is designed with a unique hollow flow channel structure to improve the drying efficiency and reduce the flow resistance and service life.

[0037] In this embodiment, the oil-water preliminary treatment layer 8 is a tension type Raschig ring, which is used to preliminarily separate the oil and water in the compressed air to ensure that most of the oil droplets and water are effectively removed before entering the subsequent treatment stage.

[0038] In this embodiment, a plurality of compressed air inlet holes 701 distributed in a circumferential array are opened at the right end of the filling housing 7.

[0039] The integrated drying tower with a drying and filtering function further includes: a snap ring 10. A pressing plate 6 is fixedly connected to the left side of the filling housing 7 through the snap ring 10. The solid drying core 5 and the oil-water preliminary treatment layer 8 are separated by the pressing plate 6. A plurality of compressed air primary filtration inlet holes 601 are opened on the pressing plate 6.

[0040] A ring-shaped fixing seat 11 is clamped and fixed on the outer part of the right end of the hollow tube 9. A spring mounting seat 12 is sleeved on the left end of the ring-shaped fixing seat 11. A spring 13 is pressed between the spring mounting seat 12 and the filling housing 7. The polymer spherical filter plate 4 is pressed and contacted with the tower cover 2. A bolt 14 passes through the middle of the tower cover 2 and movably penetrates through the hollow tube 9. The right end of the bolt 14 penetrates to the right end of the air inlet and outlet integrated block 18 and is threadedly connected with a nut 15. A washer 16 and a sealing ring 17 are sequentially arranged between the left end of the bolt 14 and the tower cover 2 from left to right. The entire drying tower is installed on the air inlet and outlet integrated block 18 through the cooperation of the bolt 14 and the nut 15. Among them, a compressed air inlet channel 1801 and a compressed air exhaust channel 1802 are opened on the air inlet and outlet integrated block 18.

[0041] Working principle: Compressed air is pressed into the drying tower through the compressed air inlet channel 1801. The oil and water preliminary treatment layer 8 is located at the inlet part of the drying tower and is used to preliminarily remove oil and water in the compressed air. Subsequently, the preliminarily purified compressed air enters the solid-state drying core body, and moisture is further removed through adsorption. Finally, the compressed air passes through the polymer spherical filter plate 4 to remove residual fine particles and pollutants, ensuring the output of high-quality compressed air. The purified compressed air enters the inner cavity of the hollow tube 9 through a plurality of purified air exhaust holes 901 and is discharged through the compressed air exhaust channel 1802.
