Description

Technical Field

[0001] The utility model belongs to the technical field of water treatment, and in particular relates to a drainage pipe for water treatment. Background Art

[0002] Water treatment methods include physical treatment and chemical treatment. Physical methods include using filter materials with different pore sizes, and using adsorption or barrier methods to remove impurities in the water. The more important adsorption method is adsorption with activated carbon. The barrier method is to pass water through the filter material to prevent larger impurities from passing through, thereby obtaining cleaner water. Chemical methods use various chemicals to convert impurities in the water into substances that are less harmful to the human body, or to concentrate the impurities.

[0003] The purpose of water treatment is to improve water quality and make it meet certain water quality standards. Water supply treatment includes two categories: domestic drinking water treatment and industrial water treatment. Wastewater treatment is divided into domestic sewage treatment and industrial wastewater treatment. Therefore, from a practical point of view, the water treatment filter element cannot be used for a long time and needs to be replaced or repaired after a certain period of time, but it cannot affect the work of other water treatment pipelines, and the replacement cannot be too troublesome, otherwise it will increase costs and labor. According to different types of sewage, targeted water treatment filter elements may be better.

[0004] Therefore, a drainage pipe for water treatment is needed to solve the problem in the existing technology that the water treatment filter element cannot be used for a long time and needs to be replaced or repaired after a certain period of time, but it cannot affect the work of other water treatment pipelines, and the replacement cannot be too troublesome, otherwise it will increase costs and labor. Utility Model Content

[0005] The purpose of the present utility model is to provide a drainage pipe for water treatment to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a drainage pipe for water treatment, comprising a water inlet pipe, wherein the lower end of the water inlet pipe is fixedly connected to an upper connecting bin, the lower end of the upper connecting bin is fixedly connected to a plurality of upper curved pipes, the lower ends of the plurality of upper curved pipes are all fixedly connected to the upper connecting pipe, the lower ends of the upper connecting pipes are all fixedly connected to filter pipes through upper connecting flanges, the middle parts of the filter pipes are all slidably connected to filter elements, and the lower ends of the filter pipes are all fixedly connected to lower connecting pipes through lower connecting flanges, the lower ends of the lower connecting pipes are all fixedly connected to lower curved pipes, the lower ends of the lower curved pipes are all fixedly connected to the lower connecting bin, and the lower ends of the lower connecting bins are all fixedly connected to water outlet pipes.

[0007] It should be noted in the solution that the upper connecting bin and the lower connecting bin are both semicircular, and a connecting shaft is fixedly connected to the middle of the opposite surfaces of the upper connecting bin and the lower connecting bin.

[0008] It is further worth mentioning that one side of each of the upper connecting pipes and the lower connecting pipes is respectively installed with an upper valve or a lower valve.

[0009] It should be further explained that a flow meter is installed on one side of each of the lower curved pipes.

[0010] As a preferred embodiment, the upper and lower ends of several of the filter tubes are respectively provided with upper connecting flanges or lower connecting flanges, the corresponding upper connecting flanges and lower connecting flanges are fixedly connected by several bolts, and the lower ends of the inner curved surfaces of several of the filter tubes are fixedly connected with raised guides.

[0011] As a preferred embodiment, both sides of the upper ends of several of the filter elements are fixedly connected with symmetrical connecting blocks, the middle parts of the symmetrical connecting blocks are provided with grooves, and the grooves are slidably connected with semicircular sliding handles.

[0012] As a preferred embodiment, the types of some of the filter elements are not fixed, including but not limited to polypropylene melt-blown filter elements, activated carbon filter elements, post-antibacterial activated carbon filter elements or ceramic filter elements.

[0013] Compared with the prior art, the drainage pipe for water treatment provided by the present invention has at least the following beneficial effects:

[0014] (1) When water flows into the water inlet pipe, it passes through the upper connecting chamber and is evenly distributed to several upper curved pipes. It then passes through the upper connecting pipe, filter pipe, filter element, lower connecting pipe, lower curved pipe, lower connecting chamber and outlet pipe, thereby dividing the water flow into several streams. The water is then filtered through the filter element, thereby increasing the treatment quality of the drainage pipe for water treatment.

[0015] (2) The flow rate value measured by each flow meter can be compared with the flow rate value under normal conditions. If a large deviation occurs, it can be determined which filter element of the filter tube has a problem, and then the upper valve of the upper connecting pipe at the upper end of the corresponding filter tube and the lower valve of the lower connecting pipe at the lower end are closed. Then, the upper connecting flange and the lower connecting flange are opened, and the corresponding filter tube is removed for maintenance or directly replaced. This approach can perform the fastest maintenance without much impact on water treatment, thereby increasing the practicality of the drainage pipe for water treatment.

DETAILED DESCRIPTION

[0020] The present invention will be further described below with reference to the embodiments.

[0021] See also Figure 1-3 The utility model provides a drainage pipe for water treatment, comprising: an inlet pipe 1, the lower end of the inlet pipe 1 is fixedly connected to an upper connecting bin 2, the lower end of the upper connecting bin 2 is fixedly connected to a plurality of upper curved pipes 3, the lower ends of the plurality of upper curved pipes 3 are all fixedly connected to an upper connecting pipe 4, the lower ends of the upper connecting pipes 4 are all fixedly connected to filter tubes 6 through upper connecting flanges 5, the middle parts of the filter tubes 6 are all slidably connected to filter elements 13, and the lower ends of the filter tubes 6 are all fixedly connected to lower connecting pipes 8 through lower connecting flanges 7, the lower ends of the lower connecting pipes 8 are all fixedly connected to lower curved pipes 9, the lower ends of the lower curved pipes 9 are all fixedly connected to the lower connecting bin 10, and the lower ends of the lower connecting bin 10 are all fixedly connected to water outlet pipes 11.

[0022] Further as Figure 1 As shown, it is worth mentioning that the upper connecting bin 2 and the lower connecting bin 10 are both semicircular, and a connecting shaft 12 is fixedly connected to the middle of the opposite surfaces of the upper connecting bin 2 and the lower connecting bin 10. Through the shape of the upper connecting bin 2 and the lower connecting bin 10, it is convenient to connect with a number of upper curved pipes 3 or lower curved pipes 9, and the water flow is evenly distributed therein, and through the connecting shaft 12, the stability between the water inlet pipe 1 and the water outlet pipe 11 can be increased.

[0023] Further as Figure 1 As shown, it is worth mentioning that an upper valve 401 or a lower valve 801 is installed on one side of each of the upper connecting pipes 4 and the lower connecting pipes 8. Through the upper valve 401 or the lower valve 801, the water flow can be cut off when the filter tube 6 is under maintenance, which is convenient for later maintenance.

[0024] This solution has the following working process: first, after the water flows into the water inlet pipe 1, it passes through the upper connecting chamber 2 and is evenly distributed into several upper curved pipes 3, and then passes through the upper connecting pipe 4, filter pipe 6, filter element 13, lower connecting pipe 8, lower curved pipe 9, lower connecting chamber 10 and outlet pipe 11. When the flow rate value measured by a certain flow meter 901 is compared with the flow rate value under normal circumstances and a large deviation is found, it can be determined that there is a problem with the filter element 13 of the filter pipe 6. Then, the upper valve 401 of the upper connecting pipe 4 at the upper end of the corresponding filter pipe 6 and the lower valve 801 of the lower connecting pipe 8 at the lower end are closed, and then the upper connecting flange 5 and the lower connecting flange 7 are opened. The corresponding filter pipe 6 can be disassembled for maintenance or directly replaced. The above operation can be repeated for installation.

[0025] According to the above working process, it can be seen that the shapes of the upper connecting chamber 2 and the lower connecting chamber 10 facilitate interconnection with a plurality of upper curved pipes 3 or lower curved pipes 9, and evenly distribute the water flow therein. Furthermore, the connecting shaft 12 can increase the stability between the water inlet pipe 1 and the water outlet pipe 11. The upper valve 401 or the lower valve 801 can be used to cut off the water flow when the filter tube 6 is under maintenance, thereby facilitating subsequent maintenance.

[0026] Further as Figure 1 As shown, it is worth mentioning that a flow meter 901 is installed on one side of each of the lower curved pipes 9. When the flow rate value measured by the flow meter 901 is compared with the flow rate value under normal circumstances and a large deviation occurs, it can be determined that there is a problem with the filter element 13 of the filter tube 6.

[0027] Further as Figure 2 As shown, it is worth mentioning that the upper and lower ends of the several filter tubes 6 are respectively provided with upper connecting flanges 5 or lower connecting flanges 7, and the corresponding upper connecting flanges 5 and lower connecting flanges 7 are fixedly connected by a plurality of bolts, and the lower ends of the inner curved surfaces of the several filter tubes 6 are fixedly connected with protruding guides 601. The upper connecting flanges 5 or the lower connecting flanges 7 facilitate the installation and disassembly of the filter tubes 6, and the protruding guides 601 can limit the position of the filter element 13.

[0028] Further as Figure 3 As shown, it is worth mentioning that symmetrical connecting blocks 1301 are fixedly connected on both sides of the upper ends of several filter elements 13, and a groove 1302 is provided in the middle of the symmetrical connecting blocks 1301. The grooves 1302 are slidably connected to a semicircular sliding handle 1303. The symmetrical connecting blocks 1301 and the semicircular sliding handle 1303 can facilitate the installation and disassembly of the filter element 13.

[0029] Further as Figure 2As shown, it is worth mentioning that the types of the filter elements 13 are not fixed, including but not limited to polypropylene melt-blown filter elements 13, activated carbon filter elements 13, post-antibacterial activated carbon filter elements 13 or ceramic filter elements 13. According to the sewage to be treated, the filter element 13 that is more suitable for the water treatment can be freely replaced, so that the treatment can be targeted, thereby improving the efficiency and quality of the drainage pipe for water treatment.

[0030] In summary: first, after the water flows into the water inlet pipe 1, it passes through the upper connecting chamber 2 and is evenly distributed to the upper curved pipes 3, and then passes through the upper connecting pipe 4, the filter pipe 6, the filter element 13, the lower connecting pipe 8, the lower curved pipe 9, the lower connecting chamber 10 and the outlet pipe 11. When the flow rate value measured by a certain flow meter 901 is compared with the flow rate value under normal circumstances and a large deviation occurs, it can be determined that there is a problem with the filter element 13 of the filter pipe 6. Then close the upper valve 401 of the upper connecting pipe 4 at the upper end of the corresponding filter pipe 6 and the lower valve 801 of the lower connecting pipe 8 at the lower end, then open the upper connecting flange 5 and the lower connecting flange 7, remove the corresponding filter pipe 6 for maintenance or directly replace it, and repeat the above operation for installation. However, through the flow meter 901, that is, when a large deviation occurs when the flow rate value measured by a certain flow meter 901 is compared with the flow rate value under normal circumstances, it can be determined that there is a problem with the filter element 13 of the filter tube 6. The upper connecting flange 5 or the lower connecting flange 7 can facilitate the installation and disassembly of the filter tube 6, and the position of the filter element 13 can be limited by the raised guide 601. The installation and disassembly of the filter element 13 can be facilitated by the symmetrical connecting block 1301 and the semicircular sliding handle 1303. The filter element 13 can be freely replaced according to the sewage to be treated, and a filter element 13 that is more suitable for the water treatment can be replaced, so that it can become a targeted treatment, thereby improving the efficiency and quality of the drainage pipe for water treatment.
