Description

Technical Field

[0001] This invention relates to the field of molecular sieve filter element degassing, specifically a molecular sieve filter element degassing and packaging integrated machine. Background Technology

[0002] Molecular sieve filter cartridges are filter cartridges with "molecular sieves" as the core filtration medium. They utilize artificially synthesized microporous crystalline materials (commonly aluminosilicate zeolites) to selectively adsorb and sieve components in gases or liquids, thereby achieving the functions of water removal, impurity removal, gas separation, or purification. Typical applications include liquid purification, and when combined with activated carbon or membranes, they are used for liquid decolorization, acid removal, and particle removal in industries such as water purification, oil refining, chemical, electronics, and pharmaceuticals.

[0003] After a period of use, the molecular sieve filter cartridges become clogged by water, CO2, or organic vapors, resulting in a decrease in adsorption capacity. They need to be regenerated offline or scrapped entirely. For some cases of mild clogging, such as in water purification, the molecular sieve filter cartridges can be degassed and reused. However, for some cases of severe clogging, where even after degasing, the filter cartridges still cannot meet the usage standards, they should be scrapped directly.

[0004] The current method for degassing slightly clogged molecular sieve filter cartridges involves first disassembling the molecular sieve filter cartridge, removing the microporous crystalline material with effective adsorption capacity, then subjecting it to high-temperature calcination to remove the adsorbates within the micropores, and finally processing the microporous crystalline material into molecular sieve filter cartridges. This method is time-consuming in the initial disassembly stage, and foreign matter, such as debris particles generated during disassembly, is easily mixed in after disassembly. Furthermore, the overall degassing process is cumbersome, time-consuming, and costly.

[0005] Therefore, a molecular sieve filter element degassing and encapsulation integrated machine is proposed to address the above problems. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

The lifting assembly includes a cover with its port facing downwards. A hydraulic cylinder is fixed to the corner of the cover and is mounted on a support frame. Multiple cylinders are arranged in a rectangular array at the top of the cover, and each cylinder is equipped with a negative pressure pipe. The degassing assembly includes a horizontal rectangular frame, with multiple degassing tubes arranged in a rectangular array within the frame. Each degassing tube contains a filter element with degassing treatment. The lower ends of the multiple degassing tubes are provided with a sliding sealing plate, and all the multiple degassing tubes are connected to an air supply pipe. The packaging box includes a box body and a packaging cover, which can seal the degassed filter element in the box body.

A top plate is provided below the tray, and the top plate is fixed to the guide rail. The top plate is used to lift the filter element in the preparation station.

[0009] Preferably, a push box assembly is symmetrically arranged on the side wall away from the support frame on the pallet, and the push box assembly includes a rotating rod rotatably connected to the pallet, an L-shaped rod fixed to the end of the rotating rod, and a push rod fixed to the end of the L-shaped rod extending downward. The push rod cooperates with the sliding pallet to push the box body below the degassing assembly.

[0010] Preferably, a rectangular cover is fixed to one side of the cover body, and multiple adsorption tubes are arranged in a rectangular array at the top inside the rectangular cover. The rectangular cover covers the upper surface of the tray, and the adsorption tubes are inserted into the central hole of the filter element.

[0011] Preferably, the rectangular frame is provided with a push plate, the end of which is rotatably connected to the bottom of the rectangular frame by a torsion spring and is located close to the rectangular cover. A touch switch is provided on one side of the end of the push plate, and the touch switch is used to control the movement stroke of the tray.

[0012] Preferably, each of the degassing tubes has an flared upper port, and a sealing rubber layer is provided on the inner sidewall of each degassing tube upper port.

[0013] Preferably, limiting plates are symmetrically arranged on the base, the limiting plates are arranged along the length direction of the base, and the limiting plates are distributed on both sides of the box.

[0014] Preferably, the housing contains a rectangular array of multiple positioning rings, each containing a filter element; the inner surface of the encapsulation cover contains a rectangular array of multiple positioning rods, the ends of which can be inserted into the central hole of the filter element.

[0015] Preferably, the base has a rectangular array of multiple ball bearings.

[0016] Preferably, a cover plate is provided below the guide rail, which is used to cover the housing without filter elements.

[0017] The advantages of this invention are: 1. Compared with existing methods of disassembling and degassing filter cartridges, this molecular sieve filter cartridge degassing and encapsulation integrated machine can simultaneously process multiple cartridges in batches. The specific number of cartridges can be determined by designing different specifications of lifting and degassing components. In terms of degassing efficiency, it can also meet the requirements.

Then, when the cover body moves the rectangular cover down, the rectangular cover covers the filter element. The adsorption tubes are inserted into the central hole at the upper end of the filter element. The adsorption tubes pre-purge each filter element to reduce the pressure of subsequent filter element degassing. Attached Figure Description

[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0021] Reference Figure 1 - Figure 7 A molecular sieve filter element degassing and encapsulation integrated machine includes a base 1, a support frame 2 is mounted on the base 1, a lifting component is mounted at the top inside the support frame 2, a degassing component is mounted below the lifting component, and an encapsulation box 3 is placed below the degassing component. The lifting assembly includes a cover 4 with its port facing downwards. A hydraulic cylinder 5 is fixed to the corner of the cover 4. The hydraulic cylinder 5 is mounted on the support frame 2. Multiple cylinders 6 are arranged in a rectangular array at the top inside the cover 4. Each cylinder 6 is equipped with a negative pressure pipe 7. The degassing assembly includes a horizontal rectangular frame 8, with multiple degassing tubes 9 arranged in a rectangular array within the rectangular frame 8. Each degassing tube 9 contains a filter element 101 with degassing treatment. The lower ends of the multiple degassing tubes 9 are provided with a sliding sealing plate 10, and all multiple degassing tubes 9 are connected to an air supply pipe 11. The packaging box 3 includes a box body 12 and a packaging cover 13. The packaging cover 13 can seal the degassed filter element 101 in the box body 12. In this embodiment of the invention, the molecular sieve filter element degassing and encapsulation integrated machine is designed to degas the entire molecular sieve filter element, and after degassing, it is simply encapsulated to prevent secondary adsorption of the molecular sieve filter element; the negative pressure pipe 7 is connected to an external negative pressure pump, and the air supply pipe 11 is connected to an external air pump, which can blow dry hot air into the air supply pipe 11; the end of the sealing plate 10 is connected to a cylinder 32, which is fixed to both sides of the rectangular frame 8. The cylinder 32 can drive the sealing plate 10 to move, thereby sealing and opening the lower port of the degassing pipe 9; The specific working process of the molecular sieve filter element degassing and encapsulation integrated machine is as follows: First, the cylinder 32 is driven, which moves the sealing plate 10 to the lower end of the degassing pipe 9 and seals it. Then, the filter element 101 is placed vertically inside the degassing pipe 9 with the perforated end facing upwards. At this time, the degassing pipe 9, together with the sealing plate 10, supports multiple filter elements 101 on the rectangular frame 8. Then, the hydraulic cylinder 5 is driven, which moves the cover 4 downwards. A sealing ring is set on the lower edge of the cover 4, and the sealing cover covers the rectangular frame 8. At the same time, the cylinder 6 covers the cover. The filter element 101 is placed in the cylinder 6. The lower port of the cylinder 6 is aligned with the upper port of the degassing tube 9 and the filter element 101 is sealed. Then, the air pump and the negative pressure pump are driven. The air pump continuously blows dry gas with a temperature between 150-200℃ into each of the multiple degassing tubes 9. The time depends on the actual blockage of the filter element 101. The gas permeates along the surface of the filter element 101 into its central hole, blowing water, CO2 or organic vapor in the molecular sieve channels into the central hole. At the same time, the negative pressure pump is driven. The negative pressure tube 7 is inserted into the central hole of the filter element 101 and is removed from the degassing tube 9. After degassing and extraction, the hydraulic cylinder 5 moves the cover 4 upwards and resets it, placing the box 12 below the rectangular frame 8. The driving cylinder 32 drives the sealing plates 10 to disengage one by one from the lower port of the degassing pipe 9. At this time, the filter element 101 falls into the box 12 under its own weight. Then, the box 12 is pushed out and sealed by the sealing cover 13. To improve the sealing performance, sealant such as glass glue can be applied to the contact edge between the sealing cover 13 and the box 12. Then, the air is extracted from the box 12 by connecting the one-way valve 33 on the side wall of the box 12 through the air pump, thus completing the sealing process. As shown in the figure, a support rod 30 can be set on the other side of the support frame 2. One end of the support rod 30 is fixed to the cover 4, and a pressure plate 31 is set at the end of the support rod 30. The pressure plate 31 moves up and down with the cover 4. The encapsulation cover 13 seals the box 12. When a batch of filter elements 101 is degassed, the cover 4 drives the pressure plate 31 to press down on the encapsulation cover 13 to ensure the stability and sealing between the box 12 and the encapsulation cover 13. Then, the air pump is used to evacuate the air inside the box 12 to realize the linkage between the degaussing and encapsulation of the filter element 101. The overall stability is stronger, and with the help of PLC control, it has a high degree of automation. Compared to existing methods of disassembling and degassing filter elements 101, this integrated degassing and packaging machine for molecular sieve filter elements can process multiple filter elements 101 simultaneously in batches. The specific number of filter elements 101 can be designed with different specifications of lifting and degassing components. In terms of degassing efficiency, it can also meet the requirements. Furthermore, in terms of degassing effect, this integrated degassing and packaging machine for molecular sieve filter elements is more suitable for mildly clogged molecular sieve filter elements. The degassing process is relatively simple and meets the basic degassing requirements. In terms of efficiency, the integrated machine has a simple structure without complex structures, low production costs, and a small overall size. Multiple units can be set up side by side and run synchronously, making it more suitable for situations with limited workspace.

[0022] Reference Figure 1 - Figure 9 The support frame 2 is provided with a feeding assembly on one side. The feeding assembly includes a guide rail 14 fixed to the support frame 2. A rectangular support plate 15 is slidably arranged on the guide rail 14. Multiple preparation stations 34 for placing filter elements 101 are opened on the support plate 15. Each preparation station 34 has a bladder 16 on its inner surface. The bladder 16 is connected to an external air pump through an air pipe. A top plate 17 is provided below the support plate 15. The top plate 17 is fixed to the guide rail 14 and is used to lift the filter element 101 in the preparation station 34. A lead screw is installed on the guide rail 14 to drive the pallet 15 to move. The lead screw is connected to a servo motor, which is controlled by a PLC. The servo motor can realize the forward and reverse rotation of the lead screw, thereby realizing the back-and-forth alternating movement of the pallet 15. Specifically, during material preparation, the pallet 15 is driven to the end of the guide rail 14, as shown in the figure, at the right side position of the guide rail 14. Then, the filter element 101 is placed one by one in each material preparation station 34 and temporarily supported by the top plate 17. After placement, gas is injected into the bag 1 by an external air pump. Inside the capsule 16, the capsule 16 expands and squeezes the filter element 101. At this time, the filter element 101 in each preparation station 34 is squeezed and stabilized. During subsequent feeding, the pallet 15, together with multiple filter elements 101, moves along the guide rail 14 and moves to the top of the rectangular frame 8. Then, the air pump extracts the gas from the capsule 16, and the capsule 16 no longer squeezes the filter element 101. The filter element 101 falls into each degassing pipe 9 under its own gravity. The lower port of the degassing pipe 9 has been sealed and blocked by the sealing plate 10. At this time, the feeding of the filter element 101 can be completed.

[0023] Reference Figure 1 - Figure 9 On the side wall away from the support frame 2, the pallet 15 is symmetrically provided with a push box assembly. The push box assembly includes a rotating rod 18 rotatably connected to the pallet 15. An L-shaped rod 19 is fixed to the end of the rotating rod 18. The end of the L-shaped rod 19 extends downward and is fixed to a push rod 20. The push rod 20 cooperates with the sliding pallet 15 to push the box 12 below the degassing assembly. The pusher assembly is designed to push the box 12 to a location with limited operating space, specifically below the rectangular frame 8. First, the box is prepared, and then the box 12 is pushed below the guide rail 14, as shown in the figure, to the right of the support frame 2. The box 12 presses against the push rod 20, whose sidewall is wedge-shaped. The box 12 presses against the surface of the wedge-shaped portion, while the L-shaped rod 19, in conjunction with the rotating rod 18 rotatably connected to the tray 15, deflects outwards, causing the box 12 to slide onto the base 1. After the box is prepared, when the pallet 15 pushes the filter element 101 onto the rectangular frame 8, the pallet 15 drives the push rod 20, which pushes the box 12 to the bottom of the rectangular frame 8. At the same time, the box 12 pushes away the box 12 containing the filter element 101 below the rectangular frame 8, and the box 12 containing the filter element 101 is squeezed to the left side of the support frame 2. The setting of this push box assembly realizes the automatic pushing and pushing of the box 12, which has high flexibility and is convenient for operators.

[0024] Reference Figure 1 - Figure 8 A rectangular cover 21 is fixed to one side of the cover 4. Multiple adsorption tubes 22 are arranged in a rectangular array at the top inside the rectangular cover 21. The rectangular cover 21 covers the upper surface of the support plate 15, and the adsorption tubes 22 are inserted into the central hole of the filter element 101. The rectangular cover 21 is fixed to the cover body 4 and moves with the cover body 4. After the filter element 101 is prepared, it is fixed by the compression of the bladder body 16, which can constrain the filter element 101 to a vertical state on the support plate 15. Then, when the cover body 4 moves the rectangular cover 21 down, the rectangular cover 21 covers the filter element 101. The adsorption tubes 22 are inserted into the central hole at the upper end of the filter element 101. The adsorption tubes 22 pre-pump water and air treatment of each filter element 101 to reduce the pressure of subsequent filter element 101 degassing.

[0025] Reference Figure 1 - Figure 5 The rectangular frame 8 is provided with a push plate 23. The end of the push plate 23 is rotatably connected to the bottom of the rectangular frame 8 by a torsion spring and is located close to the rectangular cover 21. A touch switch 24 is provided on one side of the end of the push plate 23. The touch switch 24 is used to control the movement stroke of the tray 15. The push plate 23 is designed to rotate only clockwise. With the help of the support plate 15 and the push rod 20, it pushes the housing 12 towards the bottom of the rectangular frame 8. At the same time, the housing 12 presses the push plate 23 to deflect, and the push plate 23 presses the trigger switch 24. The trigger switch 24 is used to control the rotation of the servo motor. Specifically, the trigger switch 24 is connected to the servo motor in conjunction with the PLC. When the housing 12 passes the push plate 23, the push plate 23 deflects and resets under the torque of the torsion spring it is connected to. The trigger switch 24 is no longer pressed by the push plate 23, and the trigger switch 24 triggers the servo motor. The servo motor drives the lead screw to rotate in the opposite direction. The lead screw drives the support plate 15 to move backward, realizing automated control and precisely controlling the movement of the support plate 15 to push the housing 12, so that the filter element 101 can accurately fall into the housing 12.

[0026] Reference Figure 5 and Figure 6 Each of the degassing tubes 9 has an flared upper port, and a sealing rubber layer is provided on the inner side wall of each degassing tube 9 upper port. The upper end of the degassing pipe 9 is flared to ensure that the filter element 101 falling from the preparation station 34 can fall accurately into the degassing pipe 9. At the same time, after the cover 4 covers the rectangular frame 8, the lower end of the cylinder 6 is pressed against the surface of the sealing rubber layer, which can further improve the sealing between the cylinder 6 and the degassing pipe 9 and reduce the possibility of gas leakage. At the same time, when the dry hot gas comes into contact with the sealing rubber layer, the sealing rubber layer expands when heated, which will further improve the sealing performance.

[0027] Reference Figure 1 - Figure 3 The base 1 is symmetrically provided with limiting plates 25, which are arranged along the length of the base 1 and are distributed on both sides of the box 12. The limiting plate 25 is set to further constrain the position of the box 12. Specifically, the box 12 enters from the right side of the base 1 and slides in along the two symmetrically set limiting plates 25. The limiting plates 25 restrict its position on both sides, so that the upper edge of the box 12 is aligned with the edge of the rectangular frame 8. At the same time, when the pressure plate 31 applies downward pressure, the pressure plate 31 can accurately press on the center position of the encapsulation cover 13 and the pressure plate 31 can press flatly inside the box 12.

[0028] Reference Figure 10 - Figure 12 The housing 12 has a rectangular array of multiple positioning rings 26 inside, and a filter element 101 is placed inside each positioning ring 26; the inner surface of the encapsulation cover 13 has a rectangular array of multiple positioning rods 27, and the ends of the positioning rods 27 can be inserted into the central hole of the filter element 101. Positioning rings 26 are provided for positioning and sealing the filter element 101, so that each filter element 101 falling into the housing 12 is positioned vertically inside the housing 12. This ensures the safety of each filter element 101 during subsequent transport of the packaging box 3, that is, that there is no collision or squeezing between the filter elements 101. At the same time, the vertical filter element 101, together with the positioning rods 27 on the packaging cover 13, seals the housing 12 with the packaging cover 13, and the positioning rods 27 are inserted into the center holes of the filter elements 101, further constraining the stability of the filter element 101 inside the housing 12.

[0029] Reference Figure 1 The base 1 is provided with a rectangular array of multiple balls 28. The balls 28 are used to convert the sliding friction between the housing 12 and the base 1 into rolling friction between the balls 28 and the housing 12, thereby reducing the moving resistance of the housing 12 and helping to improve the smoothness and stability of the movement of the housing 12.

[0030] Reference Figure 1 - Figure 3 A cover plate 29 is provided below the guide rail 14. The cover plate 29 is used to cover the box 12 where no filter element 101 is placed. When preparing the filter element 101, there may be flowing liquid or attached foreign objects on the filter element 101. In order to prevent foreign objects from falling into the housing 12, a cover plate 29 is provided below the guide rail 14. The cover plate 29 can completely cover the housing 12, and the edge of the cover plate 29 is tilted upward, which also makes it convenient for the housing 12 to be pushed onto the base 1.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
