Description

Technical Field

[0001] This utility model relates to the field of ultrapure water, and in particular to a modular equipment for ultrapure water circulation. Background Technology

[0002] Ultrapure water circulation systems are widely used in semiconductor, biomedicine, and laboratory fields. Their core component, the filter element, needs to be replaced regularly to ensure water quality. Existing laboratory ultrapure water equipment has a dispersed filtration module layout, requiring individual replacement of filter elements. There are many types and interfaces, resulting in a high learning cost for customers and making replacement difficult. Moreover, each filter canister must be removed separately and a new filter element installed inside the machine, which is inconvenient due to limited space. Utility Model Content

[0003] The purpose of this invention is to provide a modular ultrapure water circulation system to solve the problems mentioned in the background section.

[0004] The technical problem solved by this utility model is achieved through the following technical solution:

[0005] A modular ultrapure water circulation system includes a main body and a filter module. The main body has a filter module mounting cavity. The bottom of the filter module mounting cavity has grooves on both sides. A sliding plate is slidably mounted in each groove. The filter module is mounted on the upper surface of the sliding plate. A back plate is fixedly mounted on the upper surface of the sliding plate. A swing arm movable cavity is provided at each groove position on the upper surface of the sliding plate. A pressing swing arm is rotatably connected to each swing arm movable cavity. A pressing rod is connected between two pressing swing arms. A tension rod is hinged to each pressing swing arm. Each tension rod slides through the back plate. A crossbeam is fixedly connected to the two tension rods. A locking element is connected to the crossbeam. The threaded shaft of the locking element is threadedly connected to both the crossbeam and the back plate.

[0006] Preferably, a limiting cavity is provided between the two slide grooves, and a slide rod is fixedly connected to the bottom of the slide plate, the slide rod sliding through the limiting cavity.

[0026] The embodiments of this utility model will be further described in detail below with reference to the accompanying drawings:

[0027] Please see Figure 1-7This utility model provides an embodiment of an ultrapure water circulation modular equipment, comprising a main body 10 and a filter module 15. A touch control screen 11 is mounted on the upper surface of the main body 10 for equipment control. A filter module mounting cavity 16 is provided in the main body 10. Sliding grooves 21 are respectively provided on both sides of the bottom of the filter module mounting cavity 16. A sliding plate 17 is slidably mounted in the sliding grooves 21. The filter module 15 is disposed on the upper surface of the sliding plate 17. A back plate 12 is fixedly installed on the surface. A concave cavity is provided on the rear end face of the back plate 12. The filter module 15 is embedded in the concave cavity. The upper end face of the slide plate 17 is provided with a swing arm movable cavity 25 at the position corresponding to each slide groove 21. A pressing swing arm 26 is rotatably connected in each swing arm movable cavity 25. A pressing rod 23 is connected between two pressing swing arms 26. A tension rod 20 is hinged to each pressing swing arm 26. Each tension rod 20 slides through the surface. The back plate 12 has a crossbeam plate 18 fixedly connected to the two tensioning rods 20. A locking member 19 is connected to the crossbeam plate 18, and the threaded shaft of the locking member 19 is threadedly connected to both the crossbeam plate 18 and the back plate 12. After the filter element in the filter element module 15 is used up, the entire filter element module 15 is replaced to form a modular unit. During replacement, the slide plate 17 is pulled out, and the slide plate 17 slides along the slide groove 21 to the outside, exposing the filter element module 15. Meanwhile, because the slide groove 21 has a chamfered opening at the front, it is tilted after being pulled out, which facilitates the replacement of the filter module 15. At this time, rotating the locking member 19 moves the entire crossbeam plate 18 closer to the back plate 12, loosening the tension rod 20 and causing the pressing arm 26 to swing backward, thereby releasing the pressing rod 23 from its contact with the filter module 15, allowing the entire filter module 15 to be easily removed for replacement, which is very convenient.

[0028] In another embodiment, to facilitate the replacement of the filter module 15 by sliding the slide plate 17, a limiting cavity 22 is provided between the two slide grooves 21. A slide rod 24 is fixedly connected to the bottom of the slide plate 17. The slide rod 24 slides through the limiting cavity 22, so that the slide rod 24 slides along the slide rod 24, thereby ensuring that the slide plate 17 does not fall off.

[0029] In another embodiment, in order to facilitate the removal of the slide plate 17 to replace the filter module 15, a handle 14 is fixedly installed on the front end face of the back plate 12.

[0030] In another embodiment, the front end face of the back plate 12 is connected to a water inlet pipe 13, the water inlet pipe 13 is connected to the water inlet end of the filter module 15, and the water outlet end of the filter module 15 is connected to the water outlet end of the main body 10.

[0031] In practice, the staff regularly replaces the filter module 15. When the "maintenance mode" is selected on the touchscreen 11, the system automatically shuts off the water circuit and releases pressure. Holding the handle 14 at the front of the back plate 12, the staff pulls the slide plate 17 outwards. The slide plate slides along the slide groove 21 until it is fully extended. The chamfered front of the slide groove tilts the slide plate, completely exposing the filter module 15. After being extended, the slide plate naturally tilts (approximately 10°–15°), reducing the operating height and avoiding bending over, conforming to ergonomics. The slide rod 24 slides within the limiting cavity 22, limiting the horizontal displacement of the slide plate and preventing slippage or jamming, ensuring smooth pulling. The handle 14 provides a clear point of force application, avoiding direct hand contact with the filter module (potential contamination) while increasing friction. The operator rotates the locking element 19, causing the crossbeam plate 18 to move towards the back plate 12, and the tension rod 20 retracts accordingly, pressing the swing arm 26 around... The hinge point swings backward, and the clamping rod 23 disengages from the abutment state with the filter module 15. Through the linkage design of the threaded locking part and the tensioning rod, the clamping force can be released by rotating with one hand. No tools are required, making operation convenient. The threaded connection is naturally self-locking in the non-rotating state, ensuring that the filter module will not be accidentally loosened due to vibration during operation. The old filter module 15 is directly removed, and the new filter module is embedded into the concave cavity of the back plate 12. Confirm that the module is aligned with the water inlet pipe 13 and the water outlet. The filter module and the concave cavity of the back plate adopt an embedded interface, which does not require complicated alignment. The physical connection can be completed by blind insertion. The water inlet pipe 13 and the filter module adopt a quick-connect connector (concealed design). The module automatically completes the sealing connection when it is embedded to prevent leakage. Finally, push the handle 14 in the opposite direction, and the slide plate slides back to the filter installation cavity 16 along the slide groove 21, which significantly reduces downtime and reduces the risk of equipment damage due to operation errors.

[0032] It should be emphasized that the embodiments described in this utility model are illustrative rather than limiting. Therefore, this utility model is not limited to the embodiments described in the specific implementation. Any other implementation methods derived by those skilled in the art based on the technical solutions of this utility model are also within the scope of protection of this utility model.
