[0005] In order to solve the above technical problems, in the first aspect, the present application proposes a water-saving device, comprising: A bracket, wherein at least one mounting frame is provided on the bracket, a water collecting tank is provided on the mounting frame, and a first pipe is connected to the water collecting tank; An adsorption spacer, the adsorption spacer comprising a hydrophilic layer and a hydrophobic layer arranged in sequence along a first direction, the hydrophilic layer and the hydrophobic layer are both arranged on the mounting frame; after the gas passes through the hydrophilic layer and the hydrophobic layer along the first direction, the liquid condensed on the hydrophilic layer and the hydrophobic layer can flow into the water collection tank, wherein the first direction is the air flow direction; A box body is communicated with the first pipeline and is used for recovering liquid.

[0006] In the technical scheme of the embodiment of the present application, when the high humidity air contacts the water-saving device, after the water molecules in the air pass through the hydrophilic layer, some of the water molecules can combine with the hydrophilic material in the hydrophilic layer, and when the water absorption of the hydrophilic material reaches saturation, the water will flow out from the hydrophilic material. Subsequently, the high humidity air passes through the hydrophobic layer again, and the hydrophobic material in the hydrophobic place does not merge with the water molecules, and the water molecules cannot enter the inside of the hydrophobic material, and some of the water molecules condense at the hydrophobic material. When the water molecules condense into certain droplets, the water will flow out from the surface of the hydrophobic material.

At this time, the recycled water can be used as the water source of the cooling tower, thereby reducing the water consumption of the cooling tower.

In this way, by limiting the parameters of the hydrophobic material, the water resistance and air permeability of the hydrophobic material can be effectively guaranteed.

[0014] In some embodiments, the water-saving device further comprises a support net, and the support net is arranged on the connection frame; The hydrophilic layer and the hydrophobic layer are both fixed to the support net, so that the hydrophilic layer and the hydrophobic layer can be conveniently fixed to the connection frame.

[0033] In the production process of batteries, it is usually necessary to control the environment, especially the ambient temperature and humidity. This mainly involves most of the cathode powder feeding rooms, cathode coating machine head and tail, cathode cold pressing, die cutting, winding assembly, liquid injection, formation and other areas.

[0034] In order to control the ambient temperature and humidity, a HVAC system is needed to control the environment. In the process of the HVAC system controlling the environment, some equipment or components in the system need to be cooled. In the cooling process, a cooling tower is used in most cases.

[0035] Most HVAC systems use open cooling towers for cooling due to their high efficiency, low cost, low noise, and low water quality requirements. The principle of an open cooling tower is to use water evaporation to absorb heat and then use a fan for mechanical exhaust to form air flow and take away the high-humidity and high-temperature air containing water vapor, thereby achieving the purpose of cooling.

[0036] However, open cooling towers consume a lot of water when in use.

[0037] Based on the above considerations, in order to solve the problem that an open cooling tower consumes a large amount of water resources when in use, a water-saving device is designed, which includes a bracket, an adsorption isolation member and a box body, wherein at least one mounting frame is provided on the bracket, a water collecting tank is provided on the mounting frame, a first pipe is connected to the water collecting tank, and the adsorption isolation member includes a hydrophilic layer and a hydrophobic layer arranged in sequence along a first direction, the hydrophilic layer and the hydrophobic layer are both arranged on the mounting frame, the hydrophilic layer can attract water molecules, and the hydrophobic layer is hindered from merging with water molecules; after the gas passes through the hydrophilic layer and the hydrophobic layer along the first direction, the liquid condensed on the hydrophilic layer and the hydrophobic layer can flow into the water collecting tank, wherein the first direction is the air flow direction, and the box body is connected to the first pipe for recovering liquid.

[0038] In the technical scheme of the embodiment of the present application, when the high humidity air contacts the water-saving device, after the water molecules in the air pass through the hydrophilic layer, some of the water molecules can combine with the hydrophilic material in the hydrophilic layer, and when the water absorption of the hydrophilic material reaches saturation, the water will flow out from the hydrophilic material. Subsequently, the high humidity air passes through the hydrophobic layer again, and the hydrophobic material in the hydrophobic place does not merge with the water molecules, and the water molecules cannot enter the inside of the hydrophobic material, and some of the water molecules condense at the hydrophobic material. When the water molecules condense into certain droplets, the water will flow out from the surface of the hydrophobic material. The water that finally flows out will flow into the box through the water collecting tank and the first pipeline for recycling. At this time, the recycled water can be used as the water source of the cooling tower, thereby reducing the water consumption of the cooling tower.

[0039] According to some embodiments of the present application, Figure 1 It is a structural schematic diagram of the water-saving device in this application, Figure 2 for Figure 1 The enlarged schematic diagram of point A in the figure is as follows: Figure 3 for Figure 1 Side view of Figure 4 Schematic diagram of the adsorption isolation element in this application, Figure 5 This is a schematic diagram of the adsorption isolation element in this application from another perspective.

[0040] like Figure 1-Figure 5 As shown, the present application provides a water-saving device, which includes a bracket 10, an adsorption isolation member 13 and a box body (not marked in the figure), wherein at least one mounting frame 104 is provided on the bracket 10, a water collecting tank 105 is provided on the mounting frame 104, and a first pipe 106 is connected to the water collecting tank 105; the adsorption isolation member 13 includes a hydrophilic layer 131 and a hydrophobic layer 132 arranged in sequence along a first direction, the hydrophilic layer 131 and the hydrophobic layer 132 are both arranged on the mounting frame 104, the hydrophilic layer 131 can attract water molecules, and the hydrophobic layer 132 is hindered from merging with water molecules; after the gas passes through the hydrophilic layer 131 and the hydrophobic layer 132 along the first direction, the liquid condensed on the hydrophilic layer 131 and the hydrophobic layer 132 can flow into the water collecting tank 105, wherein the first direction is the air flow direction, and the box body is connected to the first pipe 106 for recovering liquid.

[0041] The first direction in this embodiment is as follows Figure 4 The X-axis direction.

[0042] Since organic matter often carries specific functional groups, they can be roughly divided into polar groups and non-polar groups. Water is a polar molecule, and according to the principle of like dissolves like, water molecules can be well integrated with polar groups. Therefore, polar groups are also called hydrophilic groups, and similarly, non-polar groups are also called hydrophobic groups.

[0043] Among them, hydrophilic groups, also known as oleophobic groups, have atomic groups that are soluble in water or easily affinity with water. They can attract water molecules or dissolve in water, and the solid surface with such functional groups is easily wetted by water.

[0044] Hydrophobic group: also known as lipophilic group or water-repellent group. It has no affinity for water and is insoluble in water or has very low solubility.

[0045] In this embodiment, the hydrophilic layer 131 is formed by a process of forming a hydrophilic material from a polymer material containing hydrophilic groups with the hydrophilic groups facing outward. The surface of the hydrophilic material can attract water molecules, and water can exhibit good wettability and adhesion on its surface.

[0046] The hydrophobic layer 132 is formed by a process of forming a hydrophobic material from a polymer material containing hydrophobic groups with the hydrophobic groups facing outward, and the hydrophobic material refers to a material with low surface energy and hydrophobicity. At the same time, it can repel water droplets, causing them to form spheres on the surface of the material and easily roll, thereby achieving a water-isolating effect.

[0047] The bracket 10 in this embodiment can be as follows Figure 1 The square structure in Figure 6 The circular structure in the figure can be determined according to actual conditions, and the embodiments of this specification do not limit this.

[0048] The adsorption isolation member 13 in this embodiment can be fixed to the installation frame 104 by gluing, snapping, etc. The specific method can be determined according to the actual situation, and this embodiment of the specification does not limit this.

[0049] When high humidity air flows along Figure 5 After flowing to the adsorption spacer 13 in the direction of the arrow, some water molecules in the air will react with the hydrophilic material in the hydrophilic layer 131 and the hydrophobic material in the hydrophobic layer 132 in the following ways: (1) When the high humidity air first meets the hydrophilic material in the hydrophilic layer 131, some water molecules combine with the hydrophilic material and are quickly absorbed by the hydrophilic material. When the hydrophilic material absorbs more water molecules, the water molecules will condense inside the hydrophilic material. When the hydrophilic material reaches saturation, the water will flow out of the hydrophilic material.

[0050] (2) When the high humidity air first hits the hydrophilic material in the hydrophilic layer 131, some water molecules pass through the gaps between the hydrophilic materials and cannot contact the hydrophilic materials, thereby reaching the surface of the hydrophobic material in the hydrophobic layer 132. Since the hydrophobic material does not fuse with the water molecules, the water molecules cannot enter the hydrophobic material, and some water molecules will condense in the hydrophobic material. When the water molecules condense into a certain amount of droplets, the water will flow out from the surface of the hydrophobic material.

[0051] (3) When the high humidity air first hits the hydrophilic material in the hydrophilic layer 131, some water molecules pass through the gaps between the hydrophilic materials and cannot contact the hydrophilic materials, thereby reaching the surface of the hydrophobic material in the hydrophobic layer 132. Since the hydrophobic material does not fuse with the water molecules, the water molecules cannot enter the inside of the hydrophobic material. Some water molecules stay on the surface of the hydrophobic material. When they are affected by the wind, they are reflected back to the surface of the hydrophilic material, and then absorbed by the hydrophilic material and condensed inside the hydrophilic material. When the hydrophilic material reaches saturation, the water will flow out of the hydrophilic material.

[0052] (4) When the high humidity air first hits the hydrophilic material in the hydrophilic layer 131, some water molecules pass through the gaps between the hydrophilic materials and cannot contact the hydrophilic materials, thereby reaching the surface of the hydrophobic material in the hydrophobic layer 132. Since the hydrophobic material does not fuse with the water molecules, the water molecules cannot enter the inside of the hydrophobic material, and some water molecules pass through the gaps in the hydrophobic material and are discharged into the atmosphere.

[0053] (5) When the high humidity air first hits the hydrophilic material in the hydrophilic layer 131, some water molecules pass through the gaps between the hydrophilic materials and cannot contact the hydrophilic materials, thereby reaching the surface of the hydrophobic material in the hydrophobic layer 132. Since the hydrophobic material does not fuse with the water molecules, the water molecules cannot enter the inside of the hydrophobic material. Some water molecules are on the surface of the hydrophobic material. When they are affected by the wind, they are reflected back to the surface of the hydrophilic material. Some water molecules pass through the gaps between the hydrophilic materials and are discharged into the atmosphere.

[0054] Therefore, when in use, when the high humidity air contacts the water-saving device, after the water molecules in the air pass through the hydrophilic layer 131, some of the water molecules can combine with the hydrophilic material in the hydrophilic layer 131, and when the water absorption of the hydrophilic material reaches saturation, water will flow out from the hydrophilic material. Subsequently, the high humidity air passes through the hydrophobic layer 132, and the hydrophobic material in the hydrophobic place does not merge with the water molecules, and the water molecules cannot enter the inside of the hydrophobic material, and some of the water molecules condense at the hydrophobic material. When the water molecules condense into certain droplets, the water will flow out from the surface of the hydrophobic material. The water that finally flows out will flow into the box through the water collecting tank 105 and the first pipeline 106 for recycling. At this time, the recycled water can be used as the water source of the cooling tower, thereby reducing the water consumption of the cooling tower. At the same time, the overall device adopts a physical process to realize the recycling of water, does not need to consume additional electric energy, and effectively reduces the cost.

[0055] According to some embodiments of the present application, Figure 1 As shown, the bracket 10 includes a plurality of side panels 101 , which are detachably connected in sequence around the circumference, and the mounting frame 104 is disposed on the side panels 101 .

[0056] refer to Figure 1 or Figure 6As shown, the side plate 101 in this embodiment includes two first connecting rods 1011 and two second connecting rods 1012, wherein the first connecting rods 1011 and the second connecting rods 1012 are sequentially connected to form the side plate 101. Of course, it can be understood that the side plate 101 can also include other structures, which are not limited here.

[0057] refer to Figure 7 Combined with Figure 2 As shown, in this embodiment, a water collecting tank 105 can be provided on the second connecting rod 1012 , and a water outlet of the water collecting tank 105 is connected to the first pipe 106 .

[0058] In this embodiment, a plurality of side plates 101 are connected by bolts around the circumference to form a Figure 1 The square bracket 10 in the embodiment of the present invention may be formed as follows: Figure 6 The circular bracket 10 in the figure can of course also be formed into brackets 10 with other structures, which is not limited in the embodiment of the present application.

[0059] When in use, since the bracket 10 is formed by connecting a plurality of side plates 101 around the circumference, the size of the entire bracket 10 can be easily adjusted by adjusting the number of the side plates 101 .

[0060] According to some embodiments of the present application, Figure 2 As shown, the installation frame 104 includes a first horizontal beam 1041, a first vertical beam 1043, a second horizontal beam 1042 and a second vertical beam 1044 connected end to end; wherein, the distance between the first horizontal beam 1041 and the second horizontal beam 1042 is adjustable, and the distance between the first vertical beam 1043 and the second vertical beam 1044 is adjustable; the water collecting tank 105 is arranged on the first horizontal beam 1041, and the adsorption isolation member 13 is arranged in the space enclosed by the first horizontal beam 1041, the first vertical beam 1043, the second horizontal beam 1042 and the second vertical beam 1044.

[0061] In this embodiment, the first cross beam 1041 and the second cross beam 1042 are both slidably connected to the first connecting rod 1011 on the side plate 101, and the first vertical beam 1043 and the second vertical beam 1044 are both slidably connected to the second connecting rod 1012 on the side plate 101. At the same time, the first vertical beam 1043 penetrates the first cross beam 1041 and the second cross beam 1042 in the vertical direction, and the first vertical beam 1043 can slide in the vertical direction relative to the first cross beam 1041 and the second cross beam 1042, and the second vertical beam 1044 penetrates the first cross beam 1041 and the second cross beam 1042 in the vertical direction, and the second vertical beam 1044 can slide in the vertical direction relative to the first cross beam 1041 and the second cross beam 1042. Of course, it can be understood that the first cross beam 1041, the second cross beam 1042, the first vertical beam 1043 and the second vertical beam 1044 can also be other connection structures, which are not limited here.

[0062] When the spacing between the first horizontal beam 1041 and the second horizontal beam 1042 is adjusted, the first horizontal beam 1041 and the second horizontal beam 1042 can be fixed to the first connecting rod 1011 by bolts. Similarly, when the spacing between the first vertical beam 1043 and the second vertical beam 1044 is adjusted, the first vertical beam 1043 and the second vertical beam 1044 can also be fixed to the second connecting rod 1012 by bolts.

[0063] In this way, by adjusting the distance between the first horizontal beam 1041 and the second horizontal beam 1042 and the distance between the first vertical beam 1043 and the second vertical beam 1044 , the size of the installation frame 104 can be easily adjusted, thereby facilitating the fixing of adsorption isolation parts 13 of different sizes in the installation frame 104 .

[0064] According to some embodiments of the present application, Figure 4 Combined with Figure 5 As shown, the water-saving device also includes a connecting frame 12, and a first water guide hole 14 is provided on the bottom wall of the connecting frame 12; the connecting frame 12 is arranged on the installation frame 104, the first water guide hole 14 is connected to the water collecting tank 105, and the adsorption isolation member 13 is arranged on the connecting frame 12.

[0065] The connection frame 12 in this embodiment can be connected to the installation frame 104 by bolts, or the connection frame 12 can be snapped into the installation frame 104. The specific details can be determined according to actual conditions, and this embodiment of the specification does not limit this.

[0066] When in use, water condensed in the hydrophilic layer 131 may flow from the first water guide holes 14 into the water collection tank 105 , and water condensed in the hydrophobic layer 132 may also flow from the first water guide holes 14 into the water collection tank 105 .

[0067] According to some embodiments of the present application, a guide surface is provided on the inner surface of the bottom wall of the connecting frame 12, the guide surface is inclined along the second direction, and the guide surface is located around the first water guide hole 14, wherein the second direction is the direction from the inner surface to the outer surface of the bottom wall of the connecting frame 12.

[0068] The second direction in this embodiment is as follows Figure 4 In the Y-axis direction, the included angle between the Y-axis and the X-axis can be 85°, 90°, etc. This embodiment is described by taking the Y-axis and the X-axis as being perpendicular to each other.

[0069] Since the guide surface is inclined downward from top to bottom relative to the inner surface, when the condensed water drops fall onto the bottom wall, they will quickly flow along the guide surface to the first water guide hole 14 .

[0070] According to some embodiments of the present application, the adsorption isolation member 13 is in a bent structure along a third direction, wherein the third direction intersects with a plane formed by the first direction and the second direction.

[0071] The third direction in this embodiment is as follows Figure 4 The Z-axis direction, wherein the angle between the Z-axis and the plane formed by the X-axis and the Y-axis can be 85°, 90°, etc. This embodiment is described by taking the example that the Z-axis is perpendicular to the plane formed by the X-axis and the Y-axis.

[0072] refer to Figure 5 As shown, in this embodiment, the distance between the hydrophilic layer 131 and the hydrophobic layer 132 is a. After the hydrophilic layer 131 is bent, the distance between the highest point to the lowest point of the hydrophilic layer 131 in the vertical direction is b. The structure of the hydrophobic layer 132 is the same as that of the hydrophilic layer 131 and will not be repeated here.

[0073] The height H of the adsorption isolation member 13 in the vertical direction is a+b, and the size of a single adsorption isolation member 13 in the horizontal direction is W, wherein H can be between 450mm-550mm, and W can be between 550mm-600mm. The specific size can be determined based on actual conditions, and the embodiments of this specification do not limit this.

[0074] Since the whole adsorption isolation member 13 is in a bent structure, the area of ​​the adsorption isolation member 13 can be increased, thereby improving the effect of condensing water.
