Scale inhibition device and water treatment system

Abstract

The application relates to a scale inhibiting device and a water treatment system, which comprises a shell, a cover and a scale inhibitor. The shell is internally defined with a first accommodating cavity and a second accommodating cavity. The shell is provided with a water inlet and a water outlet. The first accommodating cavity is communicated with the water inlet, the second accommodating cavity is communicated with the water outlet, and the water flowing into the second accommodating cavity is first reacted with the scale inhibitor in the first accommodating cavity when the water quantity flowing into the water inlet exceeds the capacity of the first accommodating cavity. The cover is arranged on the opening of the shell, and the scale inhibitor is arranged in the first accommodating cavity and the second accommodating cavity respectively. The scale inhibitor can be fully reacted with the water when the water flows through the first accommodating cavity and the second accommodating cavity in sequence, thereby preventing the formation of scale. The water flowing into the second accommodating cavity is first reacted with the scale inhibitor in the first accommodating cavity, thereby increasing the contact time of the water and the scale inhibitor, making the scale inhibitor more fully reacted with the water, and ensuring the scale inhibiting effect.

Description

Technical Field

[0001] This application relates to the field of water treatment equipment technology, and in particular to a scale inhibition device and a water treatment system. Background Technology

[0002] In various water treatment systems, scale inhibitors play a crucial role, serving as the core component for controlling water discharge.

[0003] Currently, some existing water treatment systems do not involve scale inhibition treatment, while others, although they do, can only have scale inhibition devices installed in specific locations, such as on wastewater discharge pipes or by integrating the scale inhibitor into RO filter cartridges. Integrating the scale inhibitor into the filter cartridge is easily affected by the internal space of the cartridge, which can lead to insufficient contact between the water flow and the scale inhibitor, affecting dissolution efficiency and making it easier for scale to form. On the other hand, installing the scale inhibitor only on the wastewater discharge pipe means that the scale inhibitor can only play its role when the wastewater is discharged, but it cannot play its role at the raw water inlet, pure water outlet, etc. Therefore, the current installation of scale inhibition devices still has significant limitations. Utility Model Content

[0004] Therefore, it is necessary to provide a scale inhibition device to address the problem that current scale inhibitors cannot fully react with water, thus easily forming scale.

[0005] The first aspect of this application provides a scale inhibition device, comprising:

[0006] The housing has a first receiving cavity, a second receiving cavity, a water inlet, and a water outlet. The water inlet is connected to the first receiving cavity, and the water outlet is connected to the second receiving cavity. The first receiving cavity is connected to the second receiving cavity.

[0007] A cover is provided over the opening of the housing, and the opening is positioned opposite to the water inlet and the water outlet;

[0008] The scale inhibitor is provided in both the first and second accommodating cavities; and the water entering the first accommodating cavity through the inlet can come into contact with at least a portion of the scale inhibitor in the first accommodating cavity before flowing into the second accommodating cavity, and after coming into contact with at least a portion of the scale inhibitor in the second accommodating cavity, it flows out from the outlet.

[0009] In one embodiment, the housing is provided with a partition for dividing the internal space of the housing into a first receiving cavity and a second receiving cavity.

[0010] In one embodiment, the separator and the cover form the flow channel.

[0011] In one embodiment, the flow channel is located away from the inlet or the outlet, and the flow channel is located between the separator and the cover, and the flow channel connects the first accommodating cavity and the second accommodating cavity.

[0012] In one embodiment, the scale inhibition device further includes a check valve, the inlet end of which is connected to the water inlet, and the outlet end of which is connected to the first receiving cavity. The check valve is used to control the unidirectional flow of water through the water inlet into the first receiving cavity.

[0013] In one embodiment, the scale inhibition device includes at least a first barrier element disposed within the water outlet, and the first barrier element is used to divide the water outlet to form a plurality of first flow ports.

[0014] The scale inhibition device may further include a second barrier, which is disposed in the inlet and located on the side of the check valve away from the first receiving cavity. The second barrier is used to divide the inlet to form a plurality of second flow ports.

[0015] Furthermore, the diameter of each of the first and second flow ports is smaller than the size of the scale inhibitor.

[0016] In one embodiment, both the first barrier and the second barrier are staggered rib structures.

[0017] In one embodiment, the cover covers the housing, and a seal is provided between the cover and the housing.

[0018] In one embodiment, the outer side wall of the housing is provided with a first connecting ear, the first connecting ear having a first connecting hole, the outer side wall of the cover is provided with a second connecting ear, the second connecting ear having a second connecting hole, the first connecting hole communicating with the second connecting hole, and a locking element being provided in the first connecting hole and the second connecting hole.

[0019] The second aspect of this application provides a water treatment system that incorporates the scale inhibition device provided in the first aspect of this application.

[0020] In the aforementioned scale inhibition device and water treatment system, by creating a first and a second receiving cavity within the casing and filling each cavity with a scale inhibitor, the scale inhibitor reacts fully with the water as it flows through them, thus preventing scale formation. This enhances the long-term stable operation of the scale inhibition device in complex water quality environments and avoids flow control failures and frequent maintenance issues caused by scaling. Furthermore, since the incoming water needs to react with the scale inhibitor in the first receiving cavity before flowing into the second receiving cavity, and then reacting with the scale inhibitor there, the contact time between the water and the scale inhibitor is increased, allowing the scale inhibitor to react more fully with the flowing water and ensuring the scale inhibition effect. In addition, the scale inhibition device can be installed at any location in the water treatment system, which greatly expands its applicability in water treatment systems.

[0028] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0029] In the description of this application, it should be understood that if terms such as "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0030] like Figure 4 As shown in the figure, this application provides a scale inhibitor device, including a housing 10 and a scale inhibitor 30. The housing 10 has a first receiving cavity 11 and a second receiving cavity 12, and the scale inhibitor 30 is disposed in both the first receiving cavity 11 and the second receiving cavity 12. Additionally, the housing 10 has an inlet 13 and an outlet 14. The first receiving cavity 11 is connected to the inlet 13, and the second receiving cavity 12 is connected to the outlet 14. Water entering the first receiving cavity 11 through the inlet 13 can contact at least a portion of the scale inhibitor 30 in the first receiving cavity 11 before flowing into the second receiving cavity 12, where it also contacts at least a portion of the scale inhibitor 30 before flowing out from the outlet 14. Preferably, when water is input into the first receiving cavity 11 through the inlet 13, the water in the first receiving cavity 11 will flow into the second receiving cavity 12 only after the amount of water input into the first receiving cavity 11 is greater than the water capacity that the first receiving cavity 11 can hold.

[0031] Therefore, when water flows into the first receiving cavity 11 through the inlet 13, the water reacts with the scale inhibitor 30 placed in the first receiving cavity 11. At this time, the scale inhibitor 30 reacts with calcium, magnesium and other scale-forming ions in the water to inhibit the formation of scale. As more and more water is input into the first receiving cavity 11 through the inlet 13, the water in the first receiving cavity 11 gradually reaches its limit. When water is continuously input into the first receiving cavity 11, the water in the first receiving cavity 11 will overflow and flow into the second receiving cavity 12. The second receiving cavity 12 is also equipped with scale inhibitor 30. Therefore, the water flowing from the first receiving cavity 11 into the second receiving cavity 12 can react with the scale inhibitor 30 placed in the second receiving cavity 12 again, so as to ensure that the input water can be fully consumed by the scale inhibitor 30, thereby avoiding scale formation during the subsequent discharge process and ensuring the scale inhibition effect. Therefore, by using the first receiving cavity 11 and the second receiving cavity 12 to store the scale inhibitor 30, the scale inhibitor 30 can have enough space to fully contact the input water, thereby optimizing the release efficiency and ensuring a full reaction between the scale inhibitor 30 and the water.

[0032] like Figure 1 As shown, the scale inhibitor also includes a cover 20, which defines a flow channel 15 between the cover 20 and the housing 10. The flow channel 15 can communicate with the first receiving cavity 11 and the second receiving cavity 12. In this embodiment, to ensure that the flow channel 15 can be formed between the cover 20 and the housing 10, the cover 20 needs to be set to a concave shape. At this time, a gap is formed between the concave cover 20 and the partition 16 provided in the housing 10. This gap is the flow channel 15 that can accommodate the water in the first receiving cavity 11 and the second receiving cavity 12 to flow between each other. Alternatively, the cover 20 may not be set to a concave shape, for example, it can be set to a flat plate. In this case, it is only necessary to control that there is still a gap between the partition 16 and the bottom of the flat cover 20. The setting of the gap ensures that water can still flow between the first receiving cavity 11 and the second receiving cavity 12 through the flow channel 15.

[0033] like Figure 3 or Figure 4As shown, a separator 16 is provided between the first receiving cavity 11 and the second receiving cavity 12, wherein the separator 16 can be integrally formed with the housing 10. The separator 16 can separate the scale inhibitor 30 placed in the first receiving cavity 11 from the scale inhibitor 30 placed in the second receiving cavity 12, and at the same time prevent water flowing into the first receiving cavity 11 from flowing into the second receiving cavity 12 before it has been sufficiently retained in the first receiving cavity 11. Therefore, the amount of water that the first receiving cavity 11 can hold is determined by the length of the separator 16 extending toward the cover 20. If the distance between the extended end of the separator 16 and the cover 20 is smaller, the first receiving cavity 11 can hold more water; if the distance between the extended end of the separator 16 and the cover 20 is larger, the first receiving cavity 11 can hold less water.

[0034] like Figure 1 , Figure 3 or Figure 4 As shown, a check valve 40 is also provided at the inlet 13. Most of the check valve 40 is located in the first receiving cavity 11. Its installation position is formed by the part of the housing 10 located at the inlet 13 extending into the first receiving cavity 11. The check valve 40 is installed at its installation position, and the inlet end of the check valve 40 is connected to the inlet 13, and the outlet end of the check valve 40 is connected to the first receiving cavity 11. When water flows from the inlet 13 to the first receiving cavity 11, the water can open the outlet end of the check valve 40 to allow water to flow smoothly into the first receiving cavity 11. If water flows back from the first receiving cavity 11 to the inlet 13, the outlet end of the self-holding check valve 40 will close automatically, thereby restricting the flow of water from the first receiving cavity 11 to the inlet 13. Thus, by setting the check valve 40, it can be ensured that water can only flow unidirectionally from the inlet 13 to the first receiving cavity 11, avoiding turbulence in the housing 10 and affecting the smooth flow of water.

[0035] like Figure 5 As shown, the inlet 13 is provided with a second barrier 17, and the outlet 14 is provided with a first barrier 18. Both the first barrier 18 and the second barrier 17 are interlocking rib structures. In this embodiment, the first barrier 18 and the second barrier 17 are interlocked in a cross shape.

[0036] In addition, the second barrier 17 can divide the inlet 13 into multiple second flow ports, thereby reducing the flow area of ​​the inlet 13. The first barrier 18 can divide the outlet 14 into multiple first flow ports. The diameter of the multiple first flow ports and second flow ports is smaller than the size of a single scale inhibitor 30. For example, when the scale inhibitor 30 is granular, the diameter of the flow port needs to be controlled to be smaller than the particle size of the granular scale inhibitor 30. The second barrier 17 is located upstream of the check valve 40. Therefore, before the water flows into the first receiving chamber 11, the water first passes through the second barrier 17 for filtration. The second barrier 17 can first filter out large particulate impurities in the water. Then, the water filtered by the second barrier 17 flows into the first receiving chamber 11 through the check valve 40 and reacts with the scale inhibitor 30 in the first receiving chamber 11 to initially react and remove scale ions present in the water. It should be noted that since a check valve 40 is provided at the inlet 13, which can prevent the scale inhibitor 30 in the first receiving cavity 11 from flowing out, the second barrier 17 may or may not be provided.

[0037] The first barrier 18 is located at the outlet 14. When water flows from the first receiving cavity 11 into the second receiving cavity 12, the flowing water reacts with the scale inhibitor 30 placed in the second receiving cavity 12. The scale inhibitor 30 then reacts with any remaining structural ions in the water to ensure that the output water does not form scale. When water is output from the outlet 14, the first barrier 18 blocks the scale inhibitor 30 in the second receiving cavity 12, preventing it from flowing out with the treated water and ensuring that there is always sufficient scale inhibitor 30 in the second receiving cavity 12 for reaction. Figure 1 or Figure 2 As shown, the cover 20 covers the housing 10, and a sealing element 50 is provided between the cover 20 and the housing 10. In this embodiment, the sealing element 50 can be a sealing ring. To facilitate the installation of the sealing element 50, the opening 19 of the housing 10 can be set as a stepped structure. When the housing 10 and the cover 20 are installed, the opening 19 of the housing 10 abuts against the cover 20. At this time, the cover 20 is adapted to the stepped structure at the opening 19 of the housing 10 and forms a mounting position for installing the sealing element 50. The sealing element 50 is set in this mounting position, and the sealing element 50 is interference-fitted with the cover 20 and the housing 10.

[0038] To further ensure a good seal, the mounting position of the seal 50 can be designed with a set tilt angle so that the seal 50 can better fit against the contact surfaces of the housing 10 and the cover 20 during installation. Furthermore, to prevent the seal 50 from shifting or falling off during use, a corresponding positioning structure, such as a positioning groove or positioning hole, can be provided on the cover 20 to ensure that the seal 50 is stably fixed in the predetermined position after installation. These designs effectively improve the overall sealing performance, ensuring that the first receiving cavity 11 and the second receiving cavity 12 will not leak due to poor sealing.

[0039] Specifically, the housing 10 is detachably connected to the cover 20 via the connector 60. Once the scale inhibitor 30 inside the housing 10 is depleted, the cover 20 can be opened, and the scale inhibitor 30 can be refilled into the housing 10 to ensure that there is always sufficient scale inhibitor 30 inside the housing 10 to fully react with the incoming water. It should be noted that the amount of scale inhibitor 30 in the first receiving cavity 11 and the second receiving cavity 12 can be adjusted according to different water qualities.

[0040] More specifically, the connector 60 includes a first connecting ear 61, a second connecting ear 62, and a locking element (not shown in the figure). The first connecting ears 61 are spaced apart circumferentially along the cover 20, meaning the first connecting ears 61 can be integrally formed with the cover 20, and the first connecting ears 61 can be evenly distributed around the periphery of the cover 20 to form multiple connection points. The second connecting ears 62 are spaced apart circumferentially along the housing 10. Similarly, the second connecting ears 62 can be integrally formed with the housing 20, and the first connecting ears 62 can be evenly distributed around the periphery of the housing 10 to form connection points adapted to the first connecting ears 61. In this embodiment, four first connecting ears 61 and four second connecting ears 62 are provided, and the four first connecting ears 61 and four second connecting ears 62 are located at the four corners of the housing 10 and the cover 20, respectively. In addition, the first connecting ear 61 is provided with a first connecting hole 611, and the second connecting ear 62 is provided with a second connecting hole 621. The first connecting hole 611 and the second connecting hole 621 are used to accommodate the locking member, that is, the locking member can be inserted into the first connecting hole 611 and the second connecting hole 621 provided in the first connecting ear 61 and the second connecting ear 62 to achieve a fixed connection between the first connecting ear 61 and the second connecting ear 62.

[0041] It is worth mentioning that during the installation of the housing 10 and the cover 20, it is first necessary to ensure that the first connecting hole 611 and the second connecting hole 621 on the first connecting ear 61 and the second connecting ear 62 are correctly aligned. After alignment, the locking member can be inserted into these aligned first connecting holes 611 and second connecting holes 621. The insertion of the locking member will make the first connecting ear 61 and the second connecting ear 62 tightly connected, thereby achieving a fixed connection between them.

[0042] In this way, the insertion of the locking element not only ensures a tight fit between the first connecting ear 61 and the second connecting ear 62, but also further ensures the fixed installation between the housing 10 and the cover 20. This fixed connection method has high stability and reliability, and can effectively prevent the housing 10 and the cover 20 from loosening or falling off during use, thereby ensuring the stability of the overall structural connection.

[0043] This application provides a water treatment system that employs the scale inhibition device described in any of the above embodiments. The scale inhibition device is connected to the water circuit board installed within the water treatment system. Moreover, the scale inhibition device is not limited to being installed in the wastewater discharge pipeline; it can be installed at any location within the water treatment system, such as the raw water pipeline or the pure water pipeline, thereby ensuring the efficient and stable operation of the water treatment system and the stability of the water quality.

[0044] In the scale inhibition device used here, a first receiving cavity 11 and a second receiving cavity 12 are defined within the housing 10, and scale inhibitor 30 is provided in both the first receiving cavity 11 and the second receiving cavity 12. When the inlet 13 and outlet 14 of the housing 10 are connected to the corresponding interfaces on the water circuit board, the water entering through the inlet 13 first flows into the first receiving cavity 11. The flowing water reacts with the scale inhibitor 30 stored in the first receiving cavity 11 to initially remove scale ions present in the water. Subsequently, the water in the first receiving cavity 11, after the initial reaction, overflows from the first receiving cavity 11 and flows into the second receiving cavity 12. The water flowing into the second receiving cavity 12 then reacts with the scale inhibitor 30 stored in the second receiving cavity 12 to further remove scale ions present in the water. Finally, the treated water is discharged from the outlet 14. Therefore, the first receiving cavity 11 and the second receiving cavity 12 opened in the housing 10, and the scale inhibitor 30 filled in the first receiving cavity 11 and the second receiving cavity 12, can effectively inhibit the scale formation of water in its discharge path, so as to avoid the problem of scale accumulation in the pipeline and blockage, and ensure the smooth flow of water.

[0045] Therefore, the scale inhibition device installed in this water treatment system is designed to effectively prevent scale accumulation and blockage along its discharge path. Furthermore, the installation of this scale inhibition device reduces the maintenance costs and operational burden of the water treatment system, ensuring its unobstructed operation during long-term use, thereby guaranteeing the normal operation and stability of the water treatment system and improving its overall operational efficiency.

[0046] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0047] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
