Technical Field

[0001] This utility model relates to the field of ultrapure water production technology, specifically to an ultrapure water wastewater treatment device. Background Technology

[0002] Ultrapure water is a type of high-purity water produced using distillation, deionization, reverse osmosis, or other advanced precision technologies for the preparation of ultrapure materials. Its preparation process requires multi-stage filtration of the water.

[0003] The existing utility model patent CN221491762U discloses a multi-stage filtration device for ultrapure water production. This device can filter raw water multiple times and various types of impurities, effectively preventing a large amount of impurities such as mud and sand in the raw water from directly entering the ultrapure water preparation equipment, which would cause the internal filter membrane and permeation membrane to be subjected to excessive pressure, thereby shortening their service life.

[0004] However, the first and second filter plates described in the patent are fixed. In the actual filtration process, impurities tend to accumulate on the surface of the filter plates and are difficult to remove in time, thus affecting the filtration effect and efficiency. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an ultrapure water wastewater treatment device to solve the problem that it is inconvenient to clean the filter plate, which affects the filtration effect.

The limiting rod passes through the snap-fit ​​part, and the connecting part is provided with a limiting groove corresponding to the limiting rod.

[0011] When the adjusting member moves along the first direction, it drives the limiting rod to move synchronously along the first direction so as to engage with or separate from the limiting groove.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. By setting connecting parts at both ends of the filter plate that can slide and snap into the locking part inside the box, the filter plate can be quickly disassembled when cleaning or replacement is required, avoiding the problem of inconvenient cleaning caused by the traditional fixed structure and improving the maintainability of the equipment; and by using the limiting component, the limiting rod cooperates with the limiting groove on the connecting part to effectively lock the filter plate, preventing it from loosening or shifting during the filtration process and ensuring the stability after installation.

[0014] Furthermore, the adjusting component includes a fixed seat disposed on the outer wall of the housing and a slider slidably disposed on the fixed seat, and the limiting rod is connected to the slider.

[0015] Furthermore, a return spring is provided inside the fixed base, and the return spring abuts against the fixed base and the slider.

[0016] Furthermore, the slider extends vertically to form a pull block, which protrudes from the fixed base.

[0017] Furthermore, the pull block is provided with several anti-slip patterns or grooves.

[0018] Furthermore, the mounting cavity is also provided with a horizontally extending snap-fit ​​groove, which is connected to the two snap-fit ​​parts.

[0032] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the technical solutions of this utility model are further described below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it.

[0033] In the description of this utility model, it should be noted that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are only for illustrative purposes to aid those skilled in the art and to facilitate understanding and reading. They are not intended to limit the implementation conditions of this utility model and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to the size, without affecting the effects and objectives of this utility model, should still fall within the scope of the technical content disclosed in this utility model. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of implementation of this utility model.

[0034] like Figure 1-5As shown in the figure, this utility model embodiment proposes an ultrapure water wastewater treatment device, including: a box body 10 having multiple mounting cavities 11, and each mounting cavity 11 having a locking part 12 extending vertically on its opposite side walls; a water inlet pipe is installed on one side of the box body 10, and a water outlet pipe is installed on the other side; specifically, in this embodiment, three mounting cavities 11 are used as an example; multiple filter plates 20 corresponding to the multiple mounting cavities 11, and each filter plate 20 having a connecting part 21 at both ends that can be slidably locked to two of the locking parts 12; multiple limiting components corresponding to the multiple filter plates 20, including a limiting rod 30 and an adjusting member 40 connected to the limiting rod 30; the limiting rod 30 passes through the locking part 12, and the connecting part 21 has a limiting groove 22 corresponding to the limiting rod 30; wherein, when the adjusting member 40 moves along a first direction, it drives the limiting rod 30 to move synchronously along the first direction, so as to lock to the limiting groove 22, or separate from it.

[0035] In this embodiment of the utility model, before use, the operator first inserts the connecting parts 21 of multiple filter plates 20 into the two snap-fit ​​parts 12 in the corresponding mounting cavity 11, so that the filter plates 20 are slidably installed in the corresponding positions in the housing 10 in the vertical direction, so as to achieve stable cooperation between the connecting parts 21 at both ends of the filter plates 20 and the snap-fit ​​parts 12; after installation, the operator rotates the adjusting member 40 to drive the limiting rod 30 to move in the first direction. The limiting rod 30 passes through the snap-fit ​​part 12 and inserts into the limiting groove 22 on the connecting part 21 of the filter plate 20, thereby further realizing the limiting and fixing of the filter plate 20 and ensuring the stability after installation; Subsequently, the ultrapure water wastewater to be treated is introduced into the device housing 10. The water flows through multiple filter plates 20 for staged filtration. Impurities are gradually trapped on the surface of each filter plate 20, achieving preliminary purification of the wastewater. When a large amount of impurities accumulate on the surface of the filter plate 20, affecting the filtration effect, the operator can use the operating adjustment component 40 to move the limiting rod 30 out of the limiting groove 22, thereby releasing the limiting and fixing state of the filter plate 20. Then, the filter plate 20 can be pulled out vertically upwards for cleaning or replacement. The cleaned filter plate 20 can be reinstalled and put back into use, thereby improving the economy and practicality of the device.

[0036] Specifically, such as Figure 2-4As shown in this embodiment of the utility model, the adjusting member 40 includes a fixed seat 41 disposed on the outer wall of the box 10 and a slider 42 slidably disposed on the fixed seat 41. The limiting rod 30 is connected to the slider 42. When installed in place, the operator pushes the slider 42 disposed on the outer wall of the box 10. At this time, the slider 42 slides in the first direction within its corresponding fixed seat 41. Since the slider 42 is connected to the limiting rod 30, the movement of the slider 42 will also synchronously drive the limiting rod 30 through the snap-fit ​​part 12 and into the preset limiting groove 22 on the filter plate 20 connecting part 21, thereby effectively locking the filter plate 20 and preventing it from shaking, misaligning or falling off under the impact of water flow. When a large amount of impurities accumulate on the surface of the filter plate 20 and it needs to be cleaned or replaced, the operator can slide the slider 42 in the opposite direction to drive the limiting rod 30 out of the limiting groove 22 and release the limiting fixation of the filter plate 20. Then, the filter plate 20 can be pulled out vertically for cleaning or replacement. The operation is simple and quick.

[0037] Furthermore, a return spring 43 is provided inside the fixed base 41. The return spring 43 abuts against the fixed base 41 and the slider 42. After the filter plate 20 is installed in place, the operator pushes the slider 42 and releases it. The return spring 43 can automatically drive the slider 42 to return to its original position, thereby allowing the limiting rod 30 to automatically insert into the limiting groove 22 on the connecting part 21. The operation is simple and quick. At the same time, in order to improve the convenience of disassembly operation, the slider 42 extends vertically to form a pull block 44. The pull block 44 protrudes from the fixed base 41, so that the operator can directly operate through the pull block 44 when it is necessary to disassemble or unlock the filter plate 20. In addition, the pull block 44 is provided with several anti-slip textures or anti-slip grooves to further prevent slippage during operation and affect operation.

[0038] Based on the above solutions, such as Figure 4 As shown in this embodiment of the invention, the mounting cavity 11 is further provided with a horizontally extending snap-fit ​​groove 13. The snap-fit ​​groove 13 is connected to the two snap-fit ​​parts 12 to form an integral snap-fit ​​guide structure. The snap-fit ​​groove 13 cooperates with the bottom of the filter plate 20 to effectively enhance the positioning stability of the filter plate 20 in the housing 10, prevent the filter plate 20 from shifting laterally or longitudinally during use, and improve the firmness of the filter plate 20. Secondly, in another embodiment, a rubber sealing gasket may be provided around the outer surface of the filter plate 20, so that it can fit tightly against the perimeter of the mounting cavity 11 during assembly, effectively preventing leakage of unfiltered wastewater and improving the filtration effect.

[0039] Based on the above solutions, such as Figure 5As shown in this embodiment of the invention, the end of the latching portion 12 away from the limiting component is provided with a groove 14. An elastic element 50 is provided within the groove 14 to abut against the filter plate 20. The elastic element 50 includes a fixing rod 51 located at the bottom of the groove 14, a compression spring 52 sleeved on the fixing rod 51, and a pushing plate 53. The pushing plate 53 is slidably disposed in the groove 14 and abuts against one side of the filter plate 20. The compression spring 52 abuts between the groove 14 and the pushing plate 53. When disassembly is required, the operator unlocks the filter plate 20 by sliding the slider 42. At this time, the pushing plate 53, under the action of the compression spring 52, pushes the filter plate 20 to move axially along the fixing rod 51, that is, the filter plate 20 moves along the extension direction of the latching portion 12, thereby facilitating removal for cleaning or replacement. Alternatively, in another embodiment, a handle can be provided on the filter plate 20 to further facilitate handling.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
