DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0034] It should be noted that, in the description of the present application, the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present application.

[0035] Furthermore, it should be understood that for the sake of ease of description, the sizes of the various components shown in the drawings are not drawn according to actual proportions. For example, the thickness or width of certain layers may be exaggerated relative to other layers.

[0036] It should be noted that like reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined or described in one drawing, it will not require further detailed discussion and description in the description of the subsequent drawings.

[0037] In order to solve the technical problems in the background technology, such as Figures 8 to 14 As shown, the embodiment of the present application proposes a filter column. Specifically, the filter column 1 includes a physical filter layer 11, an algae filter layer 12 and a bacterial filter layer 13 connected in sequence from the outside to the inside. The physical filter layer 11 is mainly used for physical filtration of the fluid, the algae filter layer 12 is used to kill algae in the water, and the bacterial filter layer 13 is mainly used for decomposing nutrients based on bacteria. The nutrients can be the water itself or generated after the algae die. In the embodiment of the present application, the fluid can be the water in the landscape pool or fish pond as described in the background technology.

[0038] Specifically, in the embodiments of the present application, the physical filter layer 11 can be any structure that can physically filter the fluid, such as: a common mesh filter structure, a sponge filter structure, or a filter structure made of filter cotton, cashmere cotton and other materials, etc., which are not described one by one here.

[0039] Specifically, in an embodiment of the present application, the algae filter layer 12 can be any filtering structure that can kill algae in the fluid, for example: the algae filter layer 12 can be a hollow circular tube shell structure that can pass the fluid (not shown in the figure), and particles that can kill bacteria and algae are placed in the circular tube shell structure. Since the particles that can kill bacteria and algae are existing technologies, they will not be described in detail; or the algae filter layer 12 can be a tubular structure formed by irregular winding of silk threads (not shown in the figure, you can refer to the instant noodle cake structure), specifically, the silk threads are made of materials that can kill bacteria and algae, for example: the silk threads can be polypropylene threads or other plastic threads with algaecidal and antibacterial masterbatch added. Of course, it is easy to understand that in the embodiments of the present application, the structure of the physical filter layer 11 and the structure of the bacterial filter layer 13 mentioned above may also be similar to the structure of the algae filter layer 12. For example, the physical filter layer 11 or the bacterial filter layer 13 may be a circular tube shell structure, and particles with corresponding functions are placed in the circular tube shell structure. Of course, the physical filter layer 11 or the bacterial filter layer 13 may be a tubular structure formed by irregular winding of silk threads.

[0040] Specifically, in the embodiment of the present application, the bacterial filter layer 13 can be any structure that can be used to consume nutrients in the fluid based on bacteria. For example, the bacterial filter layer 13 can be the circular tube shell structure mentioned above, and the shell structure has particles containing nitrifying bacteria; or the bacterial filter layer 13 can be a sponge tube structure, and the sponge contains nitrifying bacteria.

[0041] It is easy to understand that if the filter column 1 proposed in the embodiment of the present application is used to filter the fluid, the visible particulate matter in the fluid can be first filtered by the physical filter layer 11; then the fluid contacts the algae filter layer 12, and the algae in the fluid are killed in large quantities; finally, the killed algae become nutrients and pass through the bacterial filter layer 13 with the fluid, so that the nitrifying bacteria in the bacterial filter layer 13 can use the nutrients to multiply rapidly and in large quantities, and finally the nitrifying bacteria decompose the nutrients in the fluid into nitrogen and water. The whole process is pollution-free and does not require any energy consumption.

[0042] It should be clear that in one embodiment of the present application, the filter column 1 is applied to the filter box 2. Specifically, the physical filter layer 11, the algae filter layer 12 and the bacterial filter layer 13 form a column body. In order to facilitate the rapid disassembly or installation of the filter column 1, the filter column also includes a detachable structure arranged on the column body, and the detachable structure is used to form a detachable connection between the column body and the filter box 2.

[0043] It should be clear that the detachable structure can be a first external thread opened on the side of the column body. The filter box 2 is provided with a first internal thread, and the first internal thread and the first external thread are adapted to each other, so that the filter column 1 and the filter box 2 can be quickly screwed together.

[0044] In another embodiment of the present application, Figures 8 to 13 As shown, the detachable structure includes a connecting plate 141 and a first connecting tube 144. The connecting plate 141 is connected to one end of the column body. The first connecting tube 144 is arranged on the connecting plate 141, and the axis center lines of the first connecting tube 144, the connecting plate 141 and the column body coincide. The side wall of the first connecting tube 144 is provided with a second external thread 145, and the second external thread 145 is adapted to the first internal thread. It is easy to understand that the second external thread 145 can be screwed with the first internal thread to enable the filter column 1 to be quickly connected to the filter box 2.

[0045] In another embodiment of the present application, Fig.14 As shown, the detachable structure includes a connecting plate 141, a first connecting pipe 144, and a locking member 147. The connecting plate 141 is connected to one end of the column body. The first connecting pipe 144 is arranged on the connecting plate 141, and the axis of the first connecting pipe 144, the connecting plate 141 and the column body coincide. A second connecting pipe 146 is arranged in the filter box 2, and the locking member 147 is used to connect the first connecting pipe 144 and the second connecting pipe 146.

[0046] Specifically, in the embodiment of the present application, the locking member 147 may be any component that can quickly connect two pipes, such as a throat clamp, a pipe clamp or a pipe clamp.

[0047] It should be clear that in the embodiment of the present application, the connection plate 141 can be integrally formed with the column body, and of course can also be bonded to the column body. In order to ensure the bonding stability between the connection plate 141 and the column body, as shown in FIG. Figure 12 to Figure 14 As shown, the first surface of the connection disk 141 is provided with a connection groove 142, which is adapted to the column body; the first surface is perpendicular to the axis of the connection disk 141. If the connection disk 141 and the column body need to be bonded, the column body is clamped into the connection groove 142 to make the bonding more stable.

[0048] In a specific embodiment of the present application, if the filter column 1 is threadedly connected to the filter box 2 through the connecting plate 141, in order to ensure that the connecting plate 141 and the operator or the operating tool generate a large friction force, it can be as follows: Fig.12 As shown, a plurality of anti-slip grooves 143 are provided on the side of the connecting plate 141 to increase the friction force.

[0049] In the embodiment of the present application, the center of gravity of the filter column 1 is lowered to increase the stability of the connection between the filter column 1 and the filter box 2. Fig.11 As shown, the inner diameter and outer diameter of the filter column 1 along the vertical direction are both increased. Of course, in other application scenarios, the inner diameter and outer diameter of the filter column 1 along the vertical direction can also be decreased.

[0050] It should be clear that the filter column in the embodiment of the present application has a physical filter layer, an algae filter layer and a bacterial filter layer, that is, it can achieve three filtering functions through only one filter column. Compared with the filtering method using physical filtration plus chemical agents or ultraviolet rays, it has less pollution to the environment and does not consume any energy.

[0051] After introducing the filter column proposed in the embodiment of the present application, a filter box proposed in the embodiment of the present application is introduced below. Specifically, the filter box 2 includes the filter column 1 proposed in any one of the above embodiments.

[0052] In a specific embodiment of the present application, Figures 1 to 5 As shown, the filter box 2 includes a partition assembly. Specifically, as Figures 1 to 7 As shown, the partition assembly includes a horizontal partition 5, at least one vertical partition 6, and at least two first through holes 52 opened in the horizontal partition 5. Figures 2 to 4As shown, the horizontal partition 5 is used to separate the filter box 2 so that the filter box 2 forms a flow channel 21 and a filter tank 22 that are not connected to each other, and the flow channel 21 and the filter tank 22 are distributed in sequence along the vertical direction. The vertical partition 6 is used to separate the filter tank 22 into a plurality of filter chambers that are not connected to each other. It is easy to understand that, assuming that in the embodiment of the present application, the number of vertical partitions 6 is n, then the number of filter chambers is n+1, and n is any positive integer greater than or equal to 1. Each vertical partition 6 is detachably connected to the horizontal partition 5, that is, during use, the number of filter chambers can be selected and set based on the number of vertical partitions 6. In the embodiment of the present application, the first through hole 52 has at least two functions, such as Figures 2 to 4 As shown, the first through hole 52 can be used to install the filter column 1 or to connect the filter chamber and the flow channel 21. It should be clear that Figures 2 to 4 Schematic diagram of the fluid flow path of the filter box 2 when using different partition components (i.e., path A, path B, or path C). In order to distinguish the fluid flow path lines from the device lines, the flow path lines are drawn with lighter gray lines in the accompanying drawings. In the embodiments of the present application, the fluid can be the water in the landscape pool or fish pond proposed in the background technology, or it can be the oil in the industrial application scenario, without any limitation.

[0053] In a specific embodiment of the present application, if the fluid needs to be filtered twice, Figure 2 As shown, the partition assembly may have three vertical partitions 6, in which case the vertical partitions 6 divide the filter tank 22 into four filter chambers. Figure 2 As shown, they are respectively the first filter chamber 221, the second filter chamber 222, the third filter chamber 223 and the fourth filter chamber 224. The first through hole 52 on the horizontal partition 5 located in the first filter chamber 221 and the third filter chamber 223 is installed with the filter column 1; the first through hole 52 on the horizontal partition 5 located in the second filter chamber 222 is used to connect the flow channel 21 and the second filter chamber 222, and the first through hole 52 on the horizontal partition 5 located in the fourth filter chamber 224 is used to connect the flow channel 21 and the fourth filter chamber 224. Specifically, in the embodiment of the present application, the flow path of the fluid is as follows Figure 2 As shown in route A in FIG, the fluid outside the filter box 2 enters the first filter chamber 221 through the water inlet assembly 3, and after being filtered by the filter column 1 in the first filter chamber 221, the fluid enters the flow channel 21. Figure 2 As shown, the vertical partition 6 in the middle of the three vertical partitions 6 can block the flow channel 21, and it is also provided with Figure 7The second through hole 61 shown. Due to the partitioning effect of the middle vertical partition 6, the fluid entering the flow channel 21 from the first filter chamber 221 can enter the second filter chamber 222 through the first through hole 52 connected to the second filter chamber 222, and then enter the third filter chamber 223 through the second through hole 61 on the vertical partition 6. The fluid entering the third filter chamber 223, after being filtered by the filter column 1 in the third filter chamber 223, enters the flow channel 21 again, and then can enter the fourth filter chamber 224 through the first through hole 52 connected to the fourth filter chamber 224, and finally flows out of the fourth filter chamber 224 through the drainage component 4.

[0054] In the embodiment of the present application, the water inlet assembly 3 is mainly used to input fluid into the filter box 2; and the drainage assembly 4 is used to output the fluid in the filter box 2. It is easy to understand that the water inlet assembly 3 and the drainage assembly 4 can be any structure that can input and output fluid into and out of the filter box 2. For example: the water inlet assembly 3 can be as follows Figure 3 The water inlet pipe is shown; the drainage assembly 4 can be as Figure 3 The figure shows a drainage pipe; of course, in other embodiments of the present application, the water inlet component 3 and the drainage component 4 can also be holes opened in the filter box 2 or equipment such as a pump with a pipeline, which are not listed here one by one.

[0055] It should be clear that in some embodiments of the present application (such as Figure 2 In the embodiment of the present application, it is necessary to be able to cut off the connection of the flow channel 21, and also to enable the adjacent filter chambers to be connected. In the embodiment of the present application, the flow channel 21 can be cut off or connected by designing a switch (not shown in the figure).

[0056] In the embodiment of the present application, in order to realize the function that adjacent filter chambers can be connected, the vertical partition 6 can be as follows: Figure 7 As shown, a second through hole 61 is provided on the vertical partition 6, and the second through hole 61 is used to connect two adjacent filter chambers. Alternatively, when the vertical partition 6 is designed, the height of the vertical partition 6 along the vertical direction is lower than the height of the filter chamber along the vertical direction, so that the fluid can flow over the vertical partition 6 from one filter chamber to another filter chamber.

[0057] In the embodiment of the present application, in order to realize that the vertical partition 6 can cut off or connect the flow channel 21, as shown in FIG. Figure 6 As shown, the horizontal partition 5 is provided with a plurality of plug holes 53, such as Figure 7As shown, a plug strip 62 is formed at the bottom of the vertical partition 6, and the plug strip 62 is adapted to the plug hole 53. The horizontal partition 5 and the vertical partition 6 can be detachably connected to the plug hole 53 through the plug strip 62. It is easy to understand that if the flow channel 21 is to be cut off, the height of the plug strip 62 in the vertical direction can be equal to the thickness of the horizontal partition 5 plus the height of the flow channel 21 in the vertical direction. If the flow channel 21 is to be connected, a hole similar to the second through hole 61 can be opened in the above-mentioned plug strip 62, or the height of the plug strip 62 in the vertical direction can be less than the thickness of the horizontal partition 5 plus the height of the flow channel 21 in the vertical direction.

[0058] As can be seen from the above, in the embodiments of the present application, Figures 2 to 4 As shown, each vertical partition 6 can cut off or connect the flow channel 21.

[0059] It should be clear that in the embodiment of the present application, in order to form a flow channel 21 between the horizontal partition 5 and the filter box 2. Figure 6 As shown, a plurality of pillars 51 are also provided at the bottom of the horizontal partition 5, which can not only be used to support the horizontal partition 5 to form the flow channel 21, but also be used to fill the gap formed between the plug-in strip 62 and the filter box 2, so that the plug-in strip 62 can completely cut off the flow channel 21.

[0060] In a specific embodiment of the present application, if the fluid needs to be filtered once, it can be as follows: Figure 3 As shown, the partition assembly may have only one vertical partition 6, which divides the filter tank 22 into a first filter chamber 221 and a second filter chamber 222. The first through hole 52 on the horizontal partition 5 in the first filter chamber 221 is installed with the filter column 1, and the first through hole 52 on the horizontal partition 5 in the second filter chamber 222 is used to connect the flow channel 21 and the second filter chamber 222. Specifically, in the embodiment of the present application, the flow path of the fluid is as follows: Figure 3 As shown in route B, the fluid located outside the filter box 2 enters the first filter chamber 221 through the water inlet component 3, and after being filtered by the filter column 1 in the first filter chamber 221, the fluid enters the flow channel 21, and then enters the second filter chamber 222 through the first through hole 52 from the flow channel 21, and finally flows out of the second filter chamber 222 through the drainage component 4.

[0061] If you need to filter the fluid once, you can also Figure 4 As shown, the partition assembly may have three vertical partitions 6, and the three vertical partitions 6 divide the filter tank 22 into four filter chambers. Figure 4As shown, they are respectively the first filter chamber 221, the second filter chamber 222, the third filter chamber 223 and the fourth filter chamber 224. The partition assembly also includes a plugging member 7, which is used to plug the first through hole 52. Specifically, a filter column 1 is set in the first filter chamber 221, and the plugging member 7 is used to plug the first through holes 52 in the second filter chamber 222 and the third filter chamber 223; the first through hole 52 on the horizontal partition 5 in the fourth filter chamber 224 is used to connect the flow channel 21 and the fourth filter chamber 224. In the embodiment of the present application, the flow path of the fluid is as follows Figure 4 As shown in route C, the fluid outside the filter box 2 enters the first filter chamber 221 through the water inlet component 3, and after being filtered by the filter column 1 in the first filter chamber 221, the fluid enters the flow channel 21, and then enters the fourth filter chamber 224 through the first through hole 52 from the flow channel 21, and finally flows out of the fourth filter chamber 224 through the drainage component 4.

[0062] It should be clear that if Figure 4 As shown, in one embodiment of the present application, a filter column 1 (not shown in the figure) can also be set in the fourth filter chamber 224, so that the fluid in the flow channel 21 can be filtered twice when entering the fourth filter chamber 224. It is easy to understand that the fluid can also be filtered three times or four times based on the above structural design...etc., which will not be described one by one here. It is easy to understand that each filtration can be any one or a combination of physical filtration, sterilization filtration or algaecide filtration.

[0063] It should be clear that in the present application, the blocking member 7 can be any component that can seal a hole. For example, the blocking member 7 can be similar to a bottle cap or a bottle stopper of a wine bottle, or the blocking member 7 can be similar to a lunch box lid, which will not be elaborated here.

[0064] In the embodiment of the present application, the horizontal partition 5 is fixed to the filter box 2. In order to facilitate the replacement of the horizontal partition 5, the horizontal partition 5 can be detachably connected or movably connected to the filter box 2. Figure 6 As shown, the horizontal partition 5 provided with the support 51 can be placed directly in the filter box 2 .

[0065] In the embodiment of the present application, there is no limitation on the shape and structure of the filter box 2, which may be a circular shell structure, or may be as follows: Figure 1 to Figure 2 In one embodiment of the present application, in order to facilitate the restriction of the position of the horizontal partition 5, as shown in the square shell structure, Figure 5As shown, the side walls of the filter box 2 are also formed with a plurality of opposite plug-in slots 23, which extend in the vertical direction and are adapted to the vertical partition 6. Specifically, the plug-in slots 23 can be directly provided on the side walls of the filter box 2, or strip-shaped protrusions can be provided on the side walls of the filter box 2, with the plug-in slots 23 formed between two adjacent strip-shaped protrusions.

[0066] It should be clear that if the insertion groove 23 is formed between the two strip-shaped protrusions, and a detachable connection is formed between the horizontal partition 5 and the filter box 2, then Figure 6 As shown, it is also necessary to provide guide holes 54 on the edge of the horizontal partition 5 corresponding to the strip-shaped protrusions, and the guide holes 54 are adapted to the corresponding strip-shaped protrusions.

[0067] It should be clear that the filter box proposed in the embodiment of the present application can separate the filter box into filter chambers with different functions. Different filtering functions can be achieved based on these filter chambers, such as single-stage physical filtration, sterilization, algae removal or multi-stage physical filtration. The filter box can be assembled based on the application scenario, thereby expanding the application scenario of the filter box.

[0068] It should also be clear that the filter column in the filter box proposed in the embodiment of the present application has a physical filter layer, an algae filter layer and a bacteria filter layer, that is, it can achieve three filtering functions through only one filter column. Compared with the filtering method using physical filtration plus chemical agents or ultraviolet rays, it has less pollution to the environment and does not consume any energy.

[0069] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
