[0003] Currently, in the air supply process for garment printing and embossing, compressed air often contains various impurities, including oil, moisture, and other impurities. Oil may clog the nozzles and affect the uniform spraying of ink, resulting in blurry printed patterns and uneven colors. Moisture can dilute and penetrate the ink, damaging the fineness of the print. Solid particulate impurities may wear down the precision parts of the equipment, reduce the service life of the equipment, increase maintenance costs, and cause serious damage to printing and embossing equipment.

[0004] Most existing gas supply purification devices have the problem of limited functionality. In order to achieve better purification results, multiple independent purification devices usually need to be connected in series. This not only makes the structure of the entire gas supply system more complex and increases the difficulty of installation and maintenance, but also occupies a lot of space. Therefore, a gas supply purification device is proposed to solve the above problems. Utility Model Content

[0020] like Figure 1-4 As shown, an air supply purification device includes a housing 1, which provides a relatively enclosed and stable space for purification. A partition plate 2 is provided inside the housing 1, which divides the interior of the housing 1 into a first purification chamber 3 and a second purification chamber 4. The second purification chamber 4 is located above the first purification chamber 3. This design allows compressed air to pass through different purification stages in a specific order, achieving gradual purification and effectively improving purification efficiency and quality.

[0021] The side of the housing 1 is provided with an air inlet 6 located above and connected to the first purification chamber 3, so that the compressed air to be purified can enter the first purification chamber 3 at a suitable angle and speed, thereby creating good conditions for subsequent oil-water separation. The bottom of the housing 1 is provided with a drain port 7 and the top is provided with an air outlet 8. The first purification chamber 3 is provided with a cyclone oil-water separation component 9 that cooperates with the air inlet 6. The second purification chamber 4 is provided with a filter component 10 and an adsorption drying component 11 arranged from bottom to top.

[0022] This design allows the compressed air to be purified to enter the first purification chamber 3 through the air inlet 6, and separate the air and oil and water through the cyclone oil-water separator 9. At the same time, due to the higher density of oil and water, they will naturally sink to the bottom of the housing 1 under the action of gravity, thus facilitating their discharge from the drain port 7. The compressed air separated by the cyclone oil-water separator 9 enters the second purification chamber 4, and after being purified again by the filter assembly 10 and the adsorption drying assembly 11, it is discharged through the air outlet 8.

[0023] In the preferred embodiment, the front of the housing 1 is provided with an opening and closing door 5 located at the second purification chamber 4, which facilitates the daily maintenance, inspection and replacement of the filter assembly 10 and the adsorption drying assembly 11. Two sets of slide rails 12 are provided on the inner wall of the second purification chamber 4, and the filter assembly 10 and the adsorption drying assembly 11 are slidably installed on the slide rails 12, thereby facilitating the disassembly and assembly of the filter assembly 10 and the adsorption drying assembly 11.

[0024] It should be noted that the door 5 is equipped with a corresponding door lock and handle, and a sealing strip is provided at the contact point between it and the housing 1.

[0025] In a preferred embodiment, the adsorption drying assembly 11 includes a first outer casing 110 and a movable perforated plate 113. The upper and lower ends of the first outer casing 110 are open to facilitate air circulation. The left and right sides of the first outer casing 110 are provided with first sliding grooves 111 that match the slide rails 12, facilitating the installation and disassembly of the adsorption drying assembly 11. Movable grooves 112 are provided on the two opposite inner walls of the first outer casing 110. The movable grooves 112 are located at the upper part of the first outer casing 110. The movable perforated plate 113 is slidably connected to the movable grooves 112 via sliding plates 114 on both sides, thereby facilitating the movement of the movable perforated plate 113 within the range of the movable grooves 112. Multiple telescopic springs 115 are provided between the inner top wall of the movable groove 112 and the top of the sliding plate 114. An electric heating mesh plate 116 is provided at the bottom of the first outer casing 110. A molecular sieve desiccant 117 is provided between the electric heating mesh plate 116 and the sliding plate 114, thereby drying the air through the molecular sieve desiccant 117.

[0026] The movable perforated plate 113 is designed so that when the molecular sieve desiccant 117 expands in volume after adsorbing moisture and oil molecules, the movable perforated plate 113 will move upward under the action of the telescopic spring 115, providing expansion space for the molecular sieve desiccant 117 and avoiding a decrease in adsorption effect due to compression. In addition, the design of the electric heating mesh plate 116 allows compressed air to be heated when passing through the electric heating mesh plate 116, reducing the relative humidity of the air and thus improving the adsorption effect of the molecular sieve desiccant 117. At the same time, after the molecular sieve desiccant 117 is saturated with adsorption, it can be regenerated by increasing the temperature of the electric heating mesh plate 116.

[0027] In the preferred embodiment, the electric heating mesh plate 116 is wrapped with an insulating layer to facilitate safety protection and prevent leakage accidents. The outer shell 1 is equipped with an electric controller and power supply that are electrically connected to the electric heating mesh plate 116, which can generate heat as needed.

[0028] It should be noted that the insulation layer can be ceramic fiber or mica sheet, etc., and the electronic controller and power supply are ordinary commercial products, so they will not be described in detail here.

[0029] In the preferred embodiment, the bottom of the first outer casing 110 is connected to the electric heating mesh plate 116 by screws 118, which facilitates the disassembly and replacement of the electric heating mesh plate 116.

[0030] In the preferred embodiment, the filter assembly 10 includes a second outer casing 101. The upper and lower ends of the second outer casing 101 are open, and the left and right sides are provided with second sliding grooves 102 that match the slide rail 12, so that the filter assembly 10 can slide flexibly on the slide rail 12, which facilitates maintenance and replacement of filter plates 103. Multiple filter plates 103 are arranged sequentially in the second outer casing 101. The pore size of the filter plates 103 decreases from bottom to top. This design can filter impurities in compressed air in stages. Large particles are first intercepted by the outer filter plates with larger pore sizes, medium particles are filtered by the middle filter plates, and fine particles are captured by the inner filter plates with the smallest pore sizes, thereby further improving the cleanliness of the compressed air.

[0031] In the preferred embodiment, the cyclone oil-water separator 9 includes an air outlet pipe 901 and a liquid separator plate 903. The top of the air outlet pipe 901 extends through the dividing plate 2 into the second purification chamber 4. The air outlet pipe 901 provides a channel for air flow, ensuring the continuity of the purification process. The outside of the air outlet pipe 901 is provided with spiral blades 902 corresponding to the air inlet 6. When compressed air enters the first purification chamber 3 from the air inlet 6, it will rotate at high speed along the spiral blades 902. During this process, the principle of centrifugal force is used to achieve initial separation from the air. The liquid separator plate 903 is located directly below the air outlet pipe 901 and further guides the separated air, oil and water.

[0032] Working principle: The compressed air to be purified enters the first purification chamber 3 through the air inlet 6. At the cyclone oil-water separation component 9, the air rotates at high speed along the spiral blades 902. The centrifugal force is used to make the oil and water discharged from the bottom drain port 7, thus achieving preliminary oil-water separation.

[0033] The pre-purified air enters the second purification chamber 4 through the air outlet pipe 901 and passes through the filter assembly 10, in which the multi-stage filter plates 103 intercept large, medium and small particulate impurities in sequence according to the pore size, further improving the air cleanliness.

[0034] Air continues to rise into the adsorption drying component 11, first being heated by the electric heating mesh plate 116 to reduce relative humidity, and then adsorbing the remaining moisture and oil molecules through the molecular sieve desiccant 117. The movable perforated plate 113 provides space for the adsorbed and expanded desiccant under the action of the extension spring 115.

[0035] When the molecular sieve desiccant 117 is saturated, the temperature of the electric heating grid plate 116 can be increased by the electronic controller to heat and regenerate it. Finally, the purified air is discharged from the air outlet 8 at the top of the shell 1, providing a clean air source for the garment printing and embossing equipment.

[0036] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
