Description

Technical Field

[0001] This utility model relates to the field of compressed air dryer technology, specifically to a segmented water storage device for a compressed air dryer. Background Technology

[0002] A compressed air dryer is a machine that dries compressed air. Refrigerated compressed air dryers utilize the principle of cooling air and lowering its temperature to condense and remove moisture from the air, resulting in drier air.

[0003] A search revealed a Chinese patent document [Announcement No.: CN218774434U] disclosing a segmented water storage device for a compressed air dryer. This device includes a dryer with an external filtration mechanism. The filtration mechanism comprises a first drain pipe fixedly installed on the lower surface of the dryer, a gas-liquid separator fixedly connected to the lower surface of the first drain pipe, a first water storage tank externally fitted to the gas-liquid separator, an exhaust pipe fixedly connected to the left surface of the first water storage tank penetrating the tank, and a second drain pipe fixedly connected to the lower surface of the first water storage tank, with a second water storage tank externally fitted to the second drain pipe. This segmented water storage device for a compressed air dryer uses a gas-liquid separator to expel gas from the water-liquid mixture discharged from the dryer. It filters impurities in the water using a first filter screen, a second filter screen, and an activated carbon adsorption plate. A three-way valve allows water to be drawn when needed and filtered again when not in use.

[0004] The above solution can filter the water discharged from the compressed air dryer through a segmented water storage device to achieve water resource recycling. However, considering the long-term filtration, a large amount of impurities will accumulate on the top filter screen, resulting in ineffective drainage and difficulty in cleaning. To address this problem, we propose a segmented water storage device for compressed air dryers. Utility Model Content

[0005] The purpose of this invention is to provide a segmented water storage device for a compressed air dryer to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a segmented water storage device for a compressed air dryer, comprising a dryer body and a first drain pipe, the first drain pipe being fixedly connected to the top of the dryer, a gas-liquid separator being fixedly installed on the surface of the first drain pipe, a second drain pipe being fixedly connected to the bottom of the gas-liquid separator, a water storage tank being fixedly connected to the bottom of the second drain pipe, a filter screen being fixedly installed inside the water storage tank, an activated carbon adsorption plate being fixedly installed at the bottom of the filter screen, an inspection port being provided on one side of the water storage tank, a sealing block being provided inside the inspection port, and a positioning mechanism being provided on one side of the sealing block; An early warning mechanism is fixedly installed on the water storage tank.

[0007] Preferably, the positioning mechanism includes a cover plate fixedly connected to one side of the sealing block, a housing fixedly connected to both sides of the cover plate, a spring provided inside the housing, a movable block fixedly connected to the top and bottom of the spring, a positioning rod fixedly connected to the side of the movable block away from the spring, two pressing blocks fixedly connected to one side of the movable block, and two U-shaped blocks symmetrically fixedly connected to one side of the water storage tank for use with the housing, with positioning holes for use with the positioning rods on the inner wall of the U-shaped blocks.

[0008] Preferably, the warning mechanism includes a warning box fixedly connected to the top of the water storage tank, a piston plate is provided inside the warning box, a touch sensor is fixedly connected to the top of the piston plate, a push block is fixedly connected to the bottom of the piston plate, a push rod is fixedly connected to the bottom of the push block, and a buoyancy block is fixedly connected to the bottom of the push rod. Two alarm lights are fixedly installed on the top of the warning box, and a controller is fixedly installed on one side of the dryer body. The controller is connected to the alarm light signal.

[0009] Preferably, two guide rods are fixedly connected to the top of the piston plate, and a guide hole is provided on the top of the warning box to cooperate with the guide rods.

[0010] Preferably, the surface of the sealing block is fitted with three sealing rings, and the surface of the sealing block is provided with an embedding groove for use with the sealing rings.

[0011] Preferably, a water outlet pipe is fixedly connected to one side of the water storage tank, and a valve is fixedly installed on the surface of the water outlet pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model, by providing a positioning mechanism, allows the pressing block to be moved closer to the spring. The pressing block will drive the moving block and the positioning rod to move, causing the positioning rod to retract into the housing. At this time, pulling the cover plate will move the sealing block away from the inspection port, allowing the impurities on the filter screen to be cleaned. After cleaning, align the housing and the U-shaped block, insert the sealing block into the inspection port, and the housing will enter the U-shaped block. Then, release the pressing block, and the elastic force generated by the spring will push the moving block and the positioning rod to move away from the spring, causing the positioning rod to enter the corresponding positioning hole, thus facilitating the cleaning of impurities on the filter screen. 2. This utility model, by setting up an early warning mechanism, enables water to accumulate above the filter screen when there are too many impurities on the filter screen, making filtration impossible. Under the influence of buoyancy, the buoyancy block will move upward, simultaneously driving the push rod, push block, and piston plate to move upward. The piston plate will then drive the touch sensor to move upward until the touch sensor contacts the inner wall of the warning box. The touch sensor will then send a signal to the controller, after which the controller's built-in PLC module will activate the alarm light to flash, reminding staff to perform maintenance as soon as possible, thus achieving the function of early warning.

[0015] 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.

[0016] Please see Figures 1-7 As shown, Example 1: A segmented water storage device for a compressed air dryer includes a dryer body 1 and a first drain pipe 2. The first drain pipe 2 is fixedly connected to the top of the dryer. A gas-liquid separator 3 is fixedly installed on the surface of the first drain pipe 2. A second drain pipe 4 is fixedly connected to the bottom of the gas-liquid separator 3. A water storage tank 5 is fixedly connected to the bottom of the second drain pipe 4. A filter screen 6 is fixedly installed inside the water storage tank 5. An activated carbon adsorption plate 7 is fixedly installed at the bottom of the filter screen 6. An inspection port 8 is opened on one side of the water storage tank 5. A sealing block 9 is provided inside the inspection port 8. A positioning mechanism is provided on one side of the sealing block 9. The early warning mechanism is fixedly installed on the water storage tank 5.

[0017] The positioning mechanism includes a cover plate 10 fixedly connected to one side of the sealing block 9. A housing 11 is fixedly connected to both sides of the cover plate 10. A spring 12 is installed inside the housing 11. A moving block 13 is fixedly connected to the top and bottom of the spring 12. A positioning rod 14 is fixedly connected to the side of the moving block 13 away from the spring 12. Two pressing blocks 15 are fixedly connected to one side of the moving block 13. Two U-shaped blocks 16 that cooperate with the housing 11 are symmetrically fixedly connected to one side of the water tank 5. The inner wall of the U-shaped block 16 is provided with positioning holes 17 that cooperate with the positioning rod 14.

[0018] In this embodiment, considering that a large amount of impurities will accumulate on the uppermost filter screen 6 after long-term filtration, resulting in ineffective drainage and difficulty in cleaning, a positioning mechanism is provided. By moving the pressing block 15 closer to the spring 12, the pressing block 15 will drive the moving block 13 and the positioning rod 14 to move, causing the positioning rod 14 to retract into the housing 11. At this time, the cover plate 10 is pulled to move the sealing block 9 away from the inspection port 8, so that the impurities on the filter screen 6 can be cleaned. After cleaning, the sealing block 9 is inserted into the inspection port 8 by aligning the housing 11 with the U-shaped block 16. At the same time, the housing 11 will enter the U-shaped block 16. Then, the pressing block 15 is released, and the elastic force generated by the spring 12 will push the moving block 13 and the positioning rod 14 to move away from the spring 12, so that the positioning rod 14 enters the corresponding positioning hole 17, which facilitates the cleaning of impurities on the filter screen 6.

[0019] The surface of the sealing block 9 is fitted with three sealing rings 28, and the surface of the sealing block 9 is provided with an embedding groove 29 that is used to cooperate with the sealing rings 28.

[0020] In this embodiment, by setting a sealing ring 28, the sealing performance of the sealing block 9 can be improved, preventing the discharged water from leaking from the connection between the sealing block 9 and the inspection port 8. At the same time, the design of the embedded groove 29 can improve the tightness of the sealing ring 28 on the sealing block 9, preventing displacement.

[0021] A water outlet pipe 30 is fixedly connected to one side of the water storage tank 5, and a valve 31 is fixedly installed on the surface of the water outlet pipe 30.

[0022] In this embodiment, by setting up a water outlet pipe 30 and a valve 31, when filtered water is needed, simply opening the valve 31 will allow water to flow out from the water outlet pipe 30, thus facilitating the recycling of water resources.

[0023] Example 2: Based on Embodiment 1, in this embodiment, the sealing block 9 can be removed by the driving positioning mechanism, which facilitates the cleaning of impurities on the filter screen 6. However, considering that a large amount of impurities on the filter screen 6 may cause backflow, if the staff cannot detect it quickly, it will affect the normal operation of the dryer body 1. In this application, the warning mechanism includes a warning box 18 that is fixedly connected to the top of the water storage tank 5. A piston plate 19 is provided inside the warning box 18. A touch sensor 20 is fixedly connected to the top of the piston plate 19. A push block 21 is fixedly connected to the bottom of the piston plate 19. A push rod 22 is fixedly connected to the bottom of the push block 21. A buoyancy block 23 is fixedly connected to the bottom of the push rod 22. Two alarm lights 24 are fixedly installed on the top of the warning box 18, and a controller 25 is fixedly installed on one side of the dryer body 1. The controller 25 is connected to the alarm lights 24.

[0024] In this embodiment, by setting up an early warning mechanism, when there are too many impurities on the filter screen 6 and the filter cannot be filtered, the water will accumulate above the filter screen 6. Under the influence of buoyancy, the buoyancy block 23 will move upward, which will drive the push rod 22, the push block 21 and the piston plate 19 to move upward. The piston plate 19 will drive the touch sensor 20 to move upward until the touch sensor 20 contacts the inner wall of the warning box 18. The touch sensor 20 will send a signal to the controller 25. Then the built-in PLC module of the controller 25 will activate the alarm light 24 to flash, reminding the staff to perform maintenance as soon as possible, thus achieving the function of early warning.

[0025] Two guide rods 26 are fixedly connected to the top of the piston plate 19, and a guide hole 27 for use with the guide rods 26 is opened on the top of the warning box 18.

[0026] In this embodiment, by setting guide rod 26 and guide hole 27, when the buoyancy of water pushes the buoyancy block 23 and other structures to move upward, it can be restricted to move upward only along the trajectory of guide rod 26 and guide hole 27, thus limiting the movement trajectory.

[0027] Working principle: By moving the pressing block 15 closer to the spring 12, the pressing block 15 will drive the moving block 13 and the positioning rod 14 to move, causing the positioning rod 14 to retract into the housing 11. At this time, the cover plate 10 is pulled to move the sealing block 9 away from the access port 8, so that the impurities on the filter screen 6 can be cleaned. After cleaning, the sealing block 9 is inserted into the access port 8, aligned with the position of the housing 11 and the U-shaped block 16. At the same time, the housing 11 will enter the U-shaped block 16. Then, the pressing block 15 is released, and the elastic force generated by the spring 12 will push the moving block 13 and the positioning rod 14 to move away from the spring 12, so that the positioning rod 14 enters the corresponding positioning hole 17, which facilitates the cleaning of impurities on the filter screen 6. When there are too many impurities on the filter screen 6, making it impossible to filter, water will accumulate above the filter screen 6. Due to buoyancy, the buoyancy block 23 will move upward, which will drive the push rod 22, the push block 21, and the piston plate 19 to move upward. The piston plate 19 will then drive the touch sensor 20 to move upward until the touch sensor 20 contacts the inner wall of the warning box 18. The touch sensor 20 will then send a signal to the controller 25. After that, the built-in PLC module of the controller 25 will activate the alarm light 24 to flash, reminding the staff to perform maintenance as soon as possible, thus achieving the function of early warning.
