Description

Technical Field

[0001] The present application relates to the technical field of pulp molding production, and in particular to a resin tank and a water purification system. Background Art

[0002] In the water purification system, the hardness ions in the water are effectively removed through the resin tank to achieve water softening. In the conventional resin tank, the effective contact process between water and resin is short during operation, and the resin utilization rate is insufficient. In order to increase the flow path length, the tank height must be increased, which is not conducive to controlling the overall volume of the resin tank. In addition, during the resin regeneration process, conventional resin tanks usually need to use a central tube and a water distributor to provide a flow path for the brine to contact the resin. Not only may it not be able to fully contact the resin, but it also occupies the internal volume of the resin tank. Therefore, how to improve the utilization rate of the softening resin and the utilization rate of the brine on the basis of controlling the volume of the resin tank is an urgent problem to be solved. Summary of the invention

[0003] Based on this, it is necessary to provide a resin tank and a water purification system to solve the problem of how to improve the utilization rate of softening resin and the utilization rate of salt solution on the basis of controlling the volume of the resin tank.

[0019] A water purification system comprises the above resin tank.

[0020] The above-mentioned water purification system, the tank body includes at least two main sections and at least one connecting section, each main section is connected to the connecting section to form a continuous and curved softening flow channel in the tank body. Through the above-mentioned structural form, the length of the flow channel softening flow channel can be increased in a non-single height direction, improving the situation where the tank size is increased in a single height direction due to increasing the utilization rate of the softening resin and the salt solution, and abandoning the traditional central pipe and water distributor water diversion method, effectively improving the utilization rate of the softening resin in the water supply state, and the utilization rate of the salt solution in the salt absorption regeneration state, thereby realizing effective control of the volume of the whole machine.

[0042] Please refer to Figure 1 The resin tank 10 in one embodiment includes a tank body 100 and a softened resin 200. The tank body 100 includes at least two main sections 110 and at least one connecting section 120. The two ends of any connecting section 120 are respectively connected to a main section 110, so that a continuous and curved softening flow channel 101 is formed in the tank body 100; the softened resin 200 is accommodated in the softening flow channel 101.

[0043] It should be noted that the two ends of any connecting section 120 are respectively connected to a main section 110 so that a continuous and curved softening flow channel 101 is formed in the tank body 100. It can be understood that: any connecting section 120 has two first ends and a second end distributed at intervals, the first end is connected to one main section 110, and the second end is connected to another main section 110; each main section 110 has a softening flow channel 101, each connecting section 120 has a softening flow channel 101, and each main section 110 is connected to the connecting section 120 to form a continuous and curved softening flow channel 101 in the tank body 100.

[0044] Among them, the resin tank 10 is applied to the water purification system. When the water purification system is in the water supply state, the raw water can flow into the softening flow channel 101 from the water inlet 102 of the tank body 100, and the ions in the softening resin 200 will exchange ions with the hardness ions in the raw water, and output the soft water through the water outlet 103 of the tank body 100 to soften the raw water; when all or most of the ions in the softening resin 200 are replaced by the hardness ions, its softening ability is significantly reduced. At this time, the softening resin 200 is regenerated to restore its performance. When the water purification system is in the salt absorption regeneration state, the saline solution in the salt absorption module 60 is injected into the softening flow channel 101 of the resin tank 10 to regenerate the softening resin 200.

[0045] The above-mentioned resin tank 10, the tank body 100 includes at least two main sections 110 and at least one connecting section 120, each main section 110 is connected to the connecting section 120 to form a continuous and curved softening flow channel 101 in the tank body 100. Through the above-mentioned structural form, the length of the flow channel softening flow channel 101 can be increased in a non-single height direction, improving the situation in which the size of the tank body 100 is increased in a single height direction due to increasing the utilization rate of the softening resin 200 and the salt solution, and abandoning the traditional central pipe and water distributor water diversion method, effectively improving the utilization rate of the softening resin 200 in the water supply state and the utilization rate of the salt solution in the salt absorption regeneration state, thereby achieving effective control of the volume of the whole machine.

[0046] In an embodiment of the present application, the tank body 100 is used to load the softened resin 200. The tank body 100 is an integrated structure. For example, the tank body 100 can be integrally formed by injection molding, casting, etc., with good integrity and high structural strength. When the softened resin 200 is contained in the tank body 100, it has good sealing and is not easy to leak.

[0047] In an embodiment of the present application, the main body section 110 and the connecting section 120 are both components of the tank body 100, and the connection between the main body section 110 and the connecting section 120 can be smoothly transitioned, for example, by using an arc to make a smooth transition between the main body section 110 and the connecting section 120, thereby avoiding sharp corners or dead corners at the connection between the main body section 110 and the connecting section 120, which is conducive to the smooth flow of liquid in the softening flow channel 101.

[0048] In the embodiment of the present application, the softening resin 200 is an ion exchange resin, and the types of the softening resin 200 include unsaturated polyester resin, epoxy resin, vinyl resin, etc. Optionally, the commonly used resin is a strong acid cation exchange resin, which can remove hardness ions in raw water, thereby outputting soft water that meets the production process requirements.

[0049] Specifically, please refer to Figure 1 The flow cross section of the softening flow channel 101 is constructed to be circular.

[0050] It should be noted that the flow cross section of the softening flow channel 101 refers to the cross section perpendicular to the flow direction of the liquid in the softening flow channel 101. Through the above configuration, the flow cross section is circular, the softened resin 200 flows more smoothly in the softening flow channel 101, the flow resistance is reduced, and stress concentration is effectively avoided, which helps to reduce maintenance costs and replacement frequency.

[0051] In the embodiment of the present application, the flow cross section is configured as a circle. In other embodiments, the flow cross section may also be an ellipse, a hexagon or other irregular shapes.

[0052] More specifically, please refer to Figure 1 The ratio of the total length of the softening flow channel 101 to the flow cross-sectional diameter of the softening flow channel 101 is in the range of 3 to 50.

[0053] It should be noted that the total length of the softening channel 101 refers to the total length of the softening channel 101 extending along the bending direction of the softening channel 101. The ratio of the total length L of the softening channel 101 to the diameter D of the flow cross section refers to the aspect ratio of the softening channel 101.

[0054] Among them, the aspect ratio of the softening flow channel 101 will directly affect the flow characteristics and efficiency of the fluid. For example, the larger the aspect ratio of the softening flow channel 101, the smaller the pressure loss and the smaller the energy consumption of the liquid during the flow. Through the above settings, by limiting the aspect ratio range of the softening flow channel 101, the utilization rate of the softening resin 200 in the water supply state and the utilization rate of the salt solution in the salt absorption regeneration state can be effectively improved, thereby improving the overall performance of the water purification system.

[0055] For details about this embodiment, please refer to Figure 1 , along the bending direction of the softening flow channel 101, the area of ​​the flow cross section of the softening flow channel 101 is equal.

[0056] It is understandable that along the bending direction of the softening flow channel 101, the cross-section perpendicular to the liquid flow direction in the softening flow channel 101 is equal. Through the above arrangement, the flow cross-section is circular, the softening resin 200 flows more smoothly in the softening flow channel 101, and stress concentration is better avoided, which helps to reduce maintenance costs and replacement frequency.

[0057] In the embodiment of the present application, the flow cross section is constructed to be circular, that is, along the bending direction of the softening flow channel 101, the flow cross section is a circle with equal area.

[0058] Please refer to Figure 1 , the main body section 110 is constructed as a straight columnar structure.

[0059] Here, the straight columnar structure can be understood as: the main body section 110 is columnar, and along the extension direction of the main body section 110, the flow cross section of the main body section 110 is a cross section with equal area.

[0060] In the embodiment of the present application, the main body segment 110 is a linear columnar structure, and the linear column can be a cylindrical shape, an elliptical column shape, or other forms of columns.

[0061] In the embodiment of the present application, there are at least two main body segments 110, and the shapes and sizes of the main body segments 110 are the same. In other embodiments, the shapes and sizes of the main body segments 110 may also be different.

[0062] Please refer to Figure 1 , the connecting section 120 is constructed as a bent columnar structure.

[0063] Here, the bent columnar structure can be understood as: the connecting section 120 is columnar, and the connecting section 120 is curved as a whole along the extension direction of the main body section 110 .

[0064] In the embodiment of the present application, the connecting section 120 is a bent columnar structure, and the bent columnar structure may be a columnar structure in a bent form such as an arc-shaped bend.

[0065] For specific embodiments, please refer to Figure 1 The tank body 100 includes two main sections 110 and a connecting section 120, and the two main sections 110 are arranged side by side in the same direction.

[0066] For example, Figure 1 As shown, the two main body segments 110 are arranged in a horizontal direction (ie Figure 1 The two main sections 110 are respectively connected to the two ends of the same connecting section 120, so that the tank body 100 is in a U-shaped structure. Correspondingly, the softening flow channel 101 is also a continuous and bent U-shaped flow channel.

[0067] In an embodiment of the present application, the two main sections 110 have the same shape and size, and the two main sections 110 are symmetrically distributed at both ends of the connecting section 120, so that the tank body 100 has a left-right symmetrical structure, which can increase the length of the flow channel softening channel 101 in a non-single height direction and facilitate the smooth flow of liquid in the softening flow channel 101.

[0068] For other embodiments, please refer to Figure 2 and Figure 3 The tank body 100 includes at least three main sections 110 and at least two connecting sections 120, and the main sections 110 are distributed side by side in the same direction.

[0069] For example, Figure 2As shown, the tank body 100 has three main sections 110 and two connecting sections 120. The three main sections 110 are arranged in a horizontal direction (i.e. Figure 2 The two connecting sections 120 are arranged side by side in the horizontal direction (in the X direction shown in FIG. 1 ), and the two connecting sections 120 are also arranged side by side in the horizontal direction. Each connecting section 120 is connected to a main section 110 at both ends, so that the tank body 100 is an N-shaped structure, and accordingly, the softening flow channel 101 is also a continuous and bent N-shaped flow channel.

[0070] For example, Figure 3 As shown, the tank body 100 has four main sections 110 and three connecting sections 120. The four main sections 110 are arranged side by side in the horizontal direction, and the three connecting sections 120 are also arranged side by side in the horizontal direction. Each connecting section 120 is connected to a main section 110 at both ends, so that the tank body 100 is in a W-shaped structure, and accordingly, the softening flow channel 101 is also a continuous and bent W-shaped flow channel.

[0071] In an embodiment of the present application, the shape and size of each main section 110 are the same, and the shape and size of each connecting section 120 are the same, so as to increase the length of the flow channel softening channel 101 in a non-single height direction and facilitate the smooth flow of liquid in the softening flow channel 101.

[0072] For more specific embodiments, please refer to Figure 4 and Figure 5 The tank body 100 includes at least three main sections 110 and at least two connecting sections 120, and each main section 110 is distributed side by side along at least two different directions.

[0073] For example, Figure 5 As shown, the tank body 100 has three main sections 110 and two connecting sections 120, wherein the two main sections 110 are arranged along Figure 5 The other main body segment 110 is arranged side by side with one of the two main body segments 110 along the X direction. Figure 5 The Y direction is shown as side by side. Figure 5 The X direction and the Y direction are perpendicular to each other, and the two connecting sections 120 are perpendicular to each other, so that the overall structure of the tank body 100 is more compact.

[0074] In an embodiment of the present application, the shape and size of each main section 110 are the same, and the shape and size of each connecting section 120 are the same, so as to increase the length of the flow channel softening channel 101 in a non-single height direction and facilitate the smooth flow of liquid in the softening flow channel 101.

[0075] For more specific embodiments, please refer to Figure 6 and Figure 7 The tank body 100 includes at least three main sections 110 and at least two connecting sections 120, and each main section 110 is staggeredly distributed along at least two different directions.

[0076] For example, Figure 7 As shown, the tank body 100 has three main sections 110 and two connecting sections 120, wherein the two main sections 110 are arranged along Figure 7 The other main body segment 110 is arranged side by side with one of the two main body segments 110 along the X direction. Figure 7 The Y direction is shown as side by side. Figure 7 As shown, the X direction and the Y direction are at an angle other than 90 degrees, and the two connecting sections 120 are at an angle other than 90 degrees, so that the overall structure of the tank body 100 is more compact.

[0077] In an embodiment of the present application, the shape and size of each main section 110 are the same, and the shape and size of each connecting section 120 are the same, so as to increase the length of the flow channel softening channel 101 in a non-single height direction and facilitate the smooth flow of liquid in the softening flow channel 101.

[0078] Please refer to Figure 1 The head end and the tail end of the tank body 100 are respectively provided with a water inlet 102 and a water outlet 103, and the two ends of the softening flow channel 101 are respectively connected with the water inlet 102 and the water outlet 103.

[0079] It can be understood that when the water purification system is in the water supply state, the raw water flows through the water supply pipeline 20, the water inlet 102, the softening flow channel 101, the water outlet 103, and the water production pipeline 30 in sequence and outputs soft water to soften the raw water. Through the above arrangement, by respectively arranging the water inlet 102 and the water outlet 103 connected to the softening flow channel 101 at the head end and the tail end of the tank body 100, the length of the effective softening flow channel 101 can be maximized.

[0080] In an embodiment of the present application, the shape of the water inlet 102 can be a circular opening, a square opening or other shapes, and the number of the water inlet 102 is not limited to one. When the number of the water inlets 102 is at least two, the water inlets 102 are distributed side by side and spaced apart at the same end of the tank body 100.

[0081] In an embodiment of the present application, the shape of the water outlet 103 can be a circular opening, a square opening or other shapes, and the number of water outlets 103 is not limited to one. When the number of water outlets 103 is at least two, the water outlets 103 are distributed side by side and spaced apart at the same end of the tank body 100.

[0082] For further information, please refer to Figure 1 The resin tank 10 further includes a first partition net 300 accommodated in the tank body 100 . The first partition net 300 is located at one end of the softening flow channel 101 close to the water inlet 102 .

[0083] It should be noted that the first partition net 300 is located at one end of the softening channel 101 close to the water inlet 102, and can limit the softening resin 200 contained in the softening channel 101 at the end of the softening channel 101 close to the water inlet 102 to prevent the softening resin 200 from leaking out of the water inlet 102, while not hindering the flow of liquid in the softening channel 101.

[0084] In the embodiment of the present application, the first separator 300 has a plurality of water holes to facilitate the circulation of the liquid in the softening channel 101. Optionally, the first separator 300 is a mesh cloth or a plastic net.

[0085] For further information, please refer to Figure 1 The resin tank 10 further includes a second partition net 400 accommodated in the tank body 100 . The second partition net 400 is located at one end of the softening flow channel 101 close to the water outlet 103 .

[0086] It should be noted that the second partition net 400 is located at one end of the softening channel 101 close to the water outlet 103, and can limit the softening resin 200 contained in the softening channel 101 at the end of the softening channel 101 close to the water outlet 103 to prevent the softened resin 200 from leaking out of the water outlet 103, while not hindering the flow of liquid in the softening channel 101.

[0087] In the embodiment of the present application, the second separator 400 has a plurality of water holes to facilitate the circulation of the liquid in the softening channel 101. Optionally, the second separator 400 is a mesh cloth or a plastic net.

[0088] Please refer to Figure 1 , a water purification system in one embodiment includes the resin tank 10 described above.

[0089] It should be noted that, in addition to the resin tank 10 , the water purification system also includes a control component, other filter elements and other components.

[0090] In the above-mentioned water purification system, the tank body 100 of the resin tank 10 includes at least two main sections 110 and at least one connecting section 120, and each main section 110 is connected to the connecting section 120 to form a continuous and curved softening flow channel 101 in the tank body 100. Through the above-mentioned structural form, the length of the flow channel softening flow channel 101 can be increased in a non-single height direction, thereby improving the situation in which the size of the tank body 100 is increased in a single height direction due to increasing the utilization rate of the softening resin 200 and the salt solution, and abandoning the traditional central pipe and water distributor water diversion method, effectively improving the utilization rate of the softening resin 200 in the water supply state and the utilization rate of the salt solution in the salt absorption regeneration state, thereby achieving effective control of the volume of the whole machine.

[0091] Specifically, please refer to Figure 8The water purification system further includes a water supply pipeline 20, a water production pipeline 30, a wastewater pipeline 40, a backwash pipeline 50 and a salt absorption module 60.
