Description

Technical Field

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

[0002] In a water purification system, a resin tank is used to effectively remove hardness ions in water to soften the water quality. In a conventional resin tank, the effective contact process between water and resin during operation is short, and the resin utilization rate is insufficient. To increase the flow path length, the height of the tank body must be increased, which is not conducive to controlling the overall volume of the resin tank. In addition, during the resin regeneration process of a conventional resin tank, a central pipe and a water distributor are usually used to provide a flow path for the brine to contact the resin. This may not only fail to fully contact the resin but also occupies the internal volume of the resin tank. Therefore, how to improve the utilization rate of softening resin and brine while controlling the volume of the resin tank is an urgent problem to be solved. Utility Model Content

[0003] Based on this, in view of the problem of how to improve the utilization rate of softening resin and brine while controlling the volume of the resin tank, it is necessary to provide a resin tank and a water purification system.

[0004] A resin tank includes:

[0005] A tank body, including at least two main body segments and at least one connecting segment. Both ends of any one of the connecting segments are respectively connected to one of the main body segments, so as to form a continuous and bent softening flow path in the tank body;

[0006] Softening resin, which is accommodated in the softening flow path.

[0007] In the above resin tank, the tank body includes at least two main body segments and at least one connecting segment. Each main body segment is connected to the connecting segment to form a continuous and bent softening flow path in the tank body. Through the above structural form, the length of the softening flow path can be increased in a non-single height direction, improving the situation of increasing the tank body size in a single height direction due to improving the utilization rate of softening resin and brine. Moreover, the traditional water guiding method of the central pipe and the water distributor is abandoned, effectively improving the utilization rate of softening resin in the water supply state and the utilization rate of brine in the salt absorption and regeneration state, and effectively controlling the overall volume of the machine.

[0020] In the above water purification system, the tank body includes at least two main sections and at least one connecting section, and each main section is connected to the connecting section so as to form a continuous and bent softening flow channel in the tank body. Through the above structural form, the length of the softening flow channel can be increased in a non-single height direction, improving the situation of increasing the size of the tank body in a single height direction due to improving the utilization rate of softening resin and brine, and abandoning the traditional water guiding methods of the central pipe and the water distributor, effectively improving the utilization rate of softening resin in the water supply state and the utilization rate of brine in the salt absorption and regeneration state, and effectively controlling the volume of the whole machine.

[0042] Please refer to Figure 1 , the resin tank 10 in an embodiment includes a tank body 100 and softened resin 200. The tank body 100 includes at least two main body segments 110 and at least one connecting segment 120. Both ends of any one connecting segment 120 are respectively connected to a main body segment 110, so as to form a continuous and bent softened flow channel 101 in the tank body 100; the softened resin 200 is accommodated in the softened flow channel 101.

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

[0044] Among them, the resin tank 10 is applied to a water purification system. When the water purification system is in the water supply state, raw water can flow into the softening flow channel 101 from the water inlet 102 of the tank body 100. Ions in the softening resin 200 will exchange ions with the hardness ions in the raw water and output softened water through the water outlet 103 of the tank body 100 to achieve the softening of the raw water. When all or most of the ions in the softening resin 200 are replaced by hardness ions, its softening ability drops significantly. At this time, the softening resin 200 is regenerated to restore its performance. When the water purification system is in the salt absorption and regeneration state, the salt 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] For the above resin tank 10, the tank body 100 includes at least two main body segments 110 and at least one connecting segment 120. Each main body segment 110 is connected to the connecting segment 120 to form a continuous and bent softening flow channel 101 inside the tank body 100. Through the above structural form, the length of the flow channel softening flow channel 101 can be increased in a non-single height direction, improving the situation of increasing the size of the tank body 100 in a single height direction due to improving the utilization rate of the softening resin 200 and the salt solution, and abandoning the traditional water guiding methods of the central pipe and the water distributor, 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 and regeneration state, and effectively controlling the volume of the whole machine.

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

[0047] In an embodiment of the present application, both the main body segment 110 and the connecting segment 120 are components of the tank body 100. The connection between the main body segment 110 and the connecting segment 120 can be smoothly transitioned. For example, a circular arc is used to make a smooth transition between the main body segment 110 and the connecting segment 120, avoiding sharp corners or dead ends at the connection between the main body segment 110 and the connecting segment 120, which is beneficial to the smooth flow of the liquid in the softening flow channel 101.

[0048] In an embodiment of the present application, the softening resin 200 is an ion exchange resin. 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 type cation exchange resin, which can remove the hardness ions in the raw water and thus output softened water that meets the production process requirements.

[0049] Specifically, please refer to Figure 1 , the cross-sectional area of the softening flow channel 101 is configured to be circular.

[0050] It should be noted that the cross-sectional area of the softening flow channel 101 refers to the cross-section perpendicular to the liquid flow direction in the flow channel of the softening flow channel 101. Through the above settings, the cross-sectional area is circular, and the softening resin 200 flows more smoothly in the softening flow channel 101, reducing the flow resistance and effectively avoiding stress concentration, which helps to reduce the maintenance cost and replacement frequency.

[0051] In the embodiment of the present application, the cross-sectional area is configured to be circular. In other embodiments, the cross-sectional area can also be elliptical, hexagonal or other irregular shapes.

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

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

[0054] Among them, the aspect ratio of the softening flow channel 101 directly affects 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 process. 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 brine in the salt absorption and regeneration state can be effectively improved, thereby enhancing the overall performance of the water purification system.

[0055] Specifically in this embodiment, please refer to Figure 1 , along the bending direction of the softening flow channel 101, the cross-sectional areas of the cross-sections of the softening flow channel 101 are equal.

[0056] It can be understood that along the bending direction of the softening flow channel 101, the cross-sections perpendicular to the liquid flow direction in the flow channel of the softening flow channel 101 are equal. Through the above settings, the cross-sectional area is circular, and the softening resin 200 flows more smoothly in the softening flow channel 101, better avoiding stress concentration, which helps to reduce the maintenance cost and replacement frequency.

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

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

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

[0060] In the embodiments of the present application, the main body section 110 is a straight columnar structure, and the straight columnar shape can be a cylindrical shape, an elliptical cylindrical shape or other forms of columnar shapes.

[0061] In the embodiments of the present application, the number of the main body sections 110 is at least two, and the shapes and sizes of the main body sections 110 are the same. In other embodiments, the shapes and sizes of the main body sections 110 can 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 follows: the connecting section 120 is columnar, and the connecting section 120 is bent as a whole along the extending direction of the main body section 110.

[0064] In the embodiments of the present application, the connecting section 120 is a bent columnar structure, and the bent columnar shape can be a columnar shape with a bent form such as an arc bend.

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

[0066] For example, as Figure 1 shown, the two main body sections 110 are arranged side by side in the horizontal direction (i.e., Figure 1 the X direction shown), and the two main body sections 110 are respectively connected to both ends of the same connecting section 120, so that the tank body 100 has a U-shaped structure. Correspondingly, the softening flow channel 101 is also a continuous and bent U-shaped flow channel.

[0067] In the embodiments of the present application, the shapes and sizes of the two main body sections 110 are the same, and the two main body sections 110 are symmetrically distributed at both ends of the connecting section 120, so that the tank body 100 has a left-right symmetric structure, which can increase the length of the flow channel softening flow channel 101 in a non-single height direction and is beneficial to the smooth flow of the liquid in the softening flow channel 101.

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

[0069] For example, as Figure 2As shown, the tank body 100 has three main body segments 110 and two connecting segments 120. The three main body segments 110 are arranged side by side in the horizontal direction (i.e., Figure 2 the X direction shown), and the two connecting segments 120 are also arranged side by side in the horizontal direction. Each end of each connecting segment 120 is connected to a main body segment 110, so that the tank body 100 has an N-shaped structure. Correspondingly, the softening flow channel 101 also has a continuous and bent N-shaped flow channel.

[0070] For another example, as Figure 3 shown, the tank body 100 has four main body segments 110 and three connecting segments 120. The four main body segments 110 are arranged side by side in the horizontal direction, and the three connecting segments 120 are also arranged side by side in the horizontal direction. Each end of each connecting segment 120 is connected to a main body segment 110, so that the tank body 100 has a W-shaped structure. Correspondingly, the softening flow channel 101 also has a continuous and bent W-shaped flow channel.

[0071] In the embodiments of the present application, the shapes and sizes of the main body segments 110 are the same, and the shapes and sizes of the connecting segments 120 are the same, so as to increase the length of the softening flow channel 101 in a non-single height direction and facilitate the smooth flow of liquid in the softening flow channel 101.

[0072] Specifically, in some other embodiments, please refer to Figure 4 and Figure 5 , the tank body 100 includes at least three main body segments 110 and at least two connecting segments 120, and the main body segments 110 are arranged side by side in at least two different directions.

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

[0074] In the embodiments of the present application, the shapes and sizes of the main body segments 110 are the same, and the shapes and sizes of the connecting segments 120 are the same, so as to increase the length of the softening flow channel 101 in a non-single height direction and facilitate the smooth flow of liquid in the softening flow channel 101.

[0075] Specifically, in some other embodiments, please refer to Figure 6 and Figure 7 , the tank body 100 includes at least three main body segments 110 and at least two connecting segments 120, and the main body segments 110 are arranged staggered in at least two different directions.

[0076] For example, as Figure 7 shown, the tank body 100 has three main body segments 110 and two connecting segments 120, where two of the main body segments 110 are arranged side by side along the Figure 7 shown X direction, and the other main body segment 110 is arranged side by side with one of the two main body segments 110 along the Figure 7 shown Y direction, Figure 7 shown at a non-90-degree angle in the X and Y directions, and the two connecting segments 120 are at a non-90-degree angle, so that the overall structure of the tank body 100 is more compact.

[0077] In the embodiments of the present application, the shapes and sizes of the main body segments 110 are the same, and the shapes and sizes of the connecting segments 120 are the same, so as to increase the length of the softening flow 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 front end and the rear 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 communicated 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 product water pipeline 30 in sequence and outputs softened water to soften the raw water. Through the above settings, by respectively arranging the water inlet 102 and the water outlet 103 communicated with the softening flow channel 101 at the front end and the rear end of the tank body 100, the length of the effective softening flow channel 101 can be maximized.

[0080] In the embodiments 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 inlets 102 is not limited to one. When the number of the water inlets 102 is at least two, the water inlets 102 are arranged side by side and spaced apart at the same end of the tank body 100.

[0081] In the embodiments 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 the water outlets 103 is not limited to one. When the number of the water outlets 103 is at least two, the water outlets 103 are arranged side by side and spaced apart at the same end of the tank body 100.

[0082] Furthermore, please refer to Figure 1 , the resin tank 10 further includes a first partition net 300 accommodated in the tank body 100, and 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 accommodated in the softening channel 101 at one end of the softening channel 101 close to the water inlet 102, avoiding the leakage of the softening resin 200 from the water inlet 102, and at the same time not hindering the flow of the liquid in the softening channel 101.

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

[0085] Furthermore, please refer to Figure 1 , the resin tank 10 further includes a second partition net 400 accommodated in the tank body 100, and the second partition net 400 is located at one end of the softening 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 accommodated in the softening channel 101 at one end of the softening channel 101 close to the water outlet 103, avoiding the leakage of the softening resin 200 from the water outlet 103, and at the same time not hindering the flow of the liquid in the softening channel 101.

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

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

[0089] It should be noted that in addition to including the above-mentioned resin tank 10, the above-mentioned water purification system further includes components such as a control component and other filter elements.

[0090] For the above-mentioned water purification system, the tank body 100 of the resin tank 10 includes at least two main body segments 110 and at least one connecting segment 120. Each main body segment 110 is connected to the connecting segment 120 to form a continuous and bent softening channel 101 in the tank body 100. Through the above structural form, the length of the softening channel 101 can be increased in a non-single height direction, improving the situation of increasing the size of the tank body 100 in a single height direction due to improving the utilization rate of the softening resin 200 and the brine, and abandoning the traditional water guiding method of the central pipe and the water distributor, effectively improving the utilization rate of the softening resin 200 in the water supply state and the utilization rate of the brine in the salt absorption and regeneration state, and effectively controlling the volume of the whole machine.
