Because different chemicals have different chemical properties, filter cartridges cannot effectively solve the problems of crystallization and impurities. Furthermore, using filter cartridges also presents the risk of cartridge clogging and subsequent pipe blockage due to cartridge failure. Utility Model Content

[0017] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

Furthermore, features defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0019] In the description of this utility model, unless otherwise explicitly defined, the terms "setting", "installing", "connecting", "linking", "connecting" and "connecting" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in combination with the specific content of the technical solution.

[0020] The following is as follows Figures 1 to 4This invention describes a pipeline liquid impurity sedimentation device according to an embodiment of the present invention.

[0021] like Figure 1 and Figure 2 As shown, the pipeline liquid impurity sedimentation device according to an embodiment of the present invention includes a filter pipe 100, a first connecting pipe 200, a water inlet pipe 300, a drain pipe 400, and a first valve 500. The filter pipe 100 includes an output section 110 at the upper end, an input section 120 in the middle, a sedimentation section 130 at the lower end, and a first inner cavity 140 running through the entire filter pipe 100 from top to bottom. A first connecting pipe 200 is connected to the top end of the output section 110. An inlet pipe 300 is disposed around the input section 120. The diameter of the input section 120 is at least 3.5 times the inner diameter of the inlet pipe 300. A drain pipe 400 is connected to the bottom end of the sedimentation section 130. A first valve 500 is installed at the output port of the drain pipe 400. The first connecting pipe 200, the inlet pipe 300, and the drain pipe 400 are respectively connected to the first inner cavity 140.

[0022] During use, the solution flows slowly into the first inner cavity 140 through the inlet pipe 300, first accumulating in the sedimentation section 130, and then rising continuously from the sedimentation section 130 to the input section 120 and the output section 110, until it is discharged from the first connecting pipe 200 located on the output section 110. During the accumulation and rising process of the solution in the first inner cavity 140, impurities inside the solution naturally settle under gravity, gathering at the sedimentation section 130. After a period of use, opening the first valve 500 allows the solution to carry the settled impurities out through the drain pipe 400, effectively preventing blockage of the entire structure.

[0023] Understandably, the design that the diameter of the input section 120 is at least 3.5 times the inner diameter of the inlet pipe 300 can cause the flow rate of the medicine to drop sharply, providing sufficient natural settling space for crystals and impurities. Furthermore, when the liquid level in the first inner cavity 140 exceeds the height of the inlet pipe 300, the continuous input of the medicine will not affect the precipitation of impurities in the medicine.

[0024] Understandably, the water inlet pipe 300 is installed at the connection point of the input section 120, ensuring sufficient pressure to maintain the continuous input of the medicine, based on the actual site conditions.

[0025] In some specific embodiments of this utility model, a transfer filter box 600 is also included. The transfer filter box 600 is disposed below the filter pipe 100. A filter assembly 610 is disposed inside the transfer filter box 600. The filter assembly 610 divides the interior of the transfer filter box 600 into a second inner cavity 620 and a third inner cavity 630. The second inner cavity 620 and the third inner cavity 630 are connected through the filter assembly 610. The second inner cavity 620 is connected to the first valve 500 through a second connecting pipe 640. The third inner cavity 630 is adapted to be connected to the outside through a third connecting pipe 660. A second valve 650 is disposed on the third connecting pipe 660.

[0026] like Figure 2 and Figure 3 As shown, in this embodiment, the filter assembly 610 is horizontally arranged inside the cavity of the transfer filter box 600, dividing the cavity of the transfer filter box 600 into a second cavity 620 and a third cavity. One end of the second connecting pipe 640 is connected to the first valve 500, and the other end passes through the transfer filter box 600 and extends into the second cavity 620. It is suitable for receiving the medicine water with sediment impurities output from the drain pipe 400 when the first valve 500 is open, and transporting it to the second cavity 620. The medicine water with sediment impurities is filtered by the filter assembly 610 in the second cavity 620, and then gathers into medicine water without sediment impurities in the third cavity 630, which can be output from the third connecting pipe 660. The second valve 650 can open or close the third connecting pipe 660 to realize the discharge control of the medicine water in the third connecting pipe 660.

[0027] Understandably, the intermediate filter box 600 is designed to filter and settle the impurity-laden liquid output from the drain pipe 400. Unlike the filter structure inside the filter pipe 100, the use of an external intermediate filter box 600 in conjunction with the first valve 500 allows the inlet pipe 300 to continue supplying the liquid while the filter assembly 610 is replaced and cleaned, improving production efficiency. Furthermore, different filter assemblies 610 can be used depending on the properties of the liquid, making the overall structure suitable for more production situations and reducing the operating costs associated with changing the structure.

[0028] Understandably, the output end of the second connecting pipe 640 is suitable for being positioned directly above the geometric center of the filter assembly 610.

[0029] It is understandable that the filter assembly 610 can be installed horizontally, vertically, or at an angle within the cavity of the transfer filter box 600.

[0030] It is understandable that when the third inner cavity 630 is located below the second cavity 620, or when the third inner cavity 630 is set apart from the second cavity 620, the connection position of the third connecting pipe 660 to the third inner cavity 630 should not be too high to prevent too much medicine from accumulating in the third inner cavity 630. However, a certain height can be set so that the medicine can be filtered and settled again to prevent impurities that have not been filtered by the filter component 610 from entering the third cavity 630.

[0031] Understandably, the space of the third inner cavity 630 must be able to accommodate at least one drainage volume of the first valve 500.

[0032] Understandably, the transfer filter box 600 should be cleaned and the filter components 610 replaced regularly.

[0033] In some specific embodiments of this utility model, the transfer filter box 600 further includes a detachably connected upper shell 670 and lower shell 680. An annular protrusion 681 is provided on the inner side of the lower shell 680, and a filter assembly 610 is horizontally disposed on the annular protrusion 681. A second connecting pipe 640 and a third connecting pipe 660 respectively pass through the lower shell 680. The filter assembly 610 is a metal filter screen.

[0034] like Figure 2 , Figure 3 and Figure 4 As shown, in this embodiment, the transfer filter box 600 is divided into an upper shell 670 and a lower shell 680 that are detachably connected. This can prevent the medicine from splashing out of the transfer filter box 600 and facilitate the replacement of the filter assembly 610. The upper surface of the annular protrusion 681 is suitable for contacting the bottom surface of the filter assembly 610, so that the filter assembly 610 can be stably placed on the annular protrusion 681.

[0035] Understandably, the filter assembly 610 and the annular protrusion 681 can also be connected by auxiliary structures such as bolts, screws, or bolt-nuts. Understandably, the metal filter screen can be recycled and is easy to clean.

[0036] In some specific embodiments of this utility model, the bottom of the lower shell 680 is provided with several supporting feet 682. For example... Figure 1 and Figure 2 As shown in this embodiment, the bottom of the lower shell 680 is provided with four evenly distributed support feet 682, which facilitates the handling and stable placement of the transfer filter box 600.

[0037] In some specific embodiments of this utility model, an output tube 700 is also included, and the first connecting tube 200 and the third connecting tube 660 are connected to the output tube 700. The horizontal plane at the output port of the output tube 700 is lower than the horizontal plane at the output port of the third connecting tube 660.

[0038] like Figure 1 , Figure 2 and Figure 3 As shown in this embodiment, the output pipe 700 is provided with three connection ports. The upper connection port is connected to the first connection pipe 200, the middle connection port is connected to the third connection pipe 660 through the second valve 650, and the lower connection port is the output port, which can output the medicine liquid.

[0039] Understandably, when the output port of the output pipe 700 cannot output the medicine, the second valve 650 should be in a closed state to prevent the medicine from flowing back into the transfer filter box 600.

[0040] It is understandable that the design of the output port of the output pipe 700 being lower than the output port of the third connecting pipe 660 is to prevent the liquid medicine output from the first connecting pipe 200 from flowing back into the transfer filter box 600 from the output pipe 700.

[0041] Understandably, the height difference between the horizontal plane of the output port of the output pipe 700 and the horizontal plane of the bottom of the transfer filter box 600 should be designed according to the structural usage scenario. When the horizontal plane of the output port of the output pipe 700 is lower than the horizontal plane of the bottom of the transfer filter box 600, a pad (not shown in the figure) can be provided at the bottom of the transfer filter box 600 to ensure that the output pipe 700 does not contact the ground while the transfer filter box 600 can be placed stably on the ground.

[0042] In some specific embodiments of this utility model, the second connecting pipe 640, the third connecting pipe 660 and the output pipe 700 are located on the same side of the transfer filter box 600.

[0043] like Figure 2 and Figure 3 As shown, in this embodiment, the second connecting pipe 640, the third connecting pipe 660 and the output pipe 700 are located on the left side of the transfer filter box 600, which facilitates the disassembly and connection of the transfer filter box 600.

[0044] In some specific embodiments of this utility model, the output part 110 is a hollow frustum structure. For example... Figure 1 and Figure 2 As shown, in this embodiment, the output section 110 adopts a hollow frustum structure, which enables the liquid in the first inner cavity 140 to be smoothly output into the first connecting pipe 200, reducing water flow resistance, enhancing structural strength, and facilitating installation and maintenance.

[0045] In some specific embodiments of this utility model, the sedimentation section 130 is a hollow frustum structure. For example... Figure 1 and Figure 2 As shown in this embodiment, Figure 1 and Figure 2As shown, in this embodiment, the sedimentation section 130 adopts a hollow frustum structure, which enables the liquid in the first inner cavity 140 to be smoothly output into the water inlet pipe 300, reducing water flow resistance, enhancing structural strength, and the hollow frustum bottom facilitates the accumulation and discharge of trapped impurities, improving the impurity removal capability.

[0046] When the device is in use, the medicine flows slowly into the first inner cavity 140 through the inlet pipe 300, first accumulating in the sedimentation section 130, and then continuously rising from the sedimentation section 130 to the input section 120 and the output section 110, until it is transported to the output pipe 700 through the first connecting pipe 200 connected to the output section 110. During the process of the medicine accumulating and rising in the first inner cavity 140, impurities inside the medicine naturally precipitate under the action of gravity and gather at the sedimentation section 130. Whenever the structure is used for a period of time, the first valve 500 is opened, and the medicine carrying the settled impurities is discharged from the drain pipe 400. It is then transported through the second connecting pipe 640 to the second inner cavity 620 of the transfer filter box 600. The medicine with settled impurities is filtered by the filter assembly 610 in the second inner cavity 620, and then settles and collects again in the third inner cavity 630. Whenever a certain amount of medicine is collected in the third inner cavity 630, the second valve 650 is opened, so that the medicine that has been filtered and settled twice in the third inner cavity 630 is transported through the third connecting pipe 660 to the output pipe 700 for output.

[0047] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
