[0002] Wastewater treatment refers to the process of purifying wastewater so that it meets the water quality requirements for discharge into a certain water body or reuse. Carbon columns are mainly used as adsorption treatment units in wastewater treatment. They are usually located in the subsequent stages of wastewater treatment and are used to deeply purify wastewater that has undergone preliminary treatment. Before replacing the activated carbon column, it is first necessary to shut down the relevant systems or equipment, such as shutting off the water source (for water treatment systems), etc., to avoid unnecessary damage or danger during the replacement process. After removing the old activated carbon column from the equipment, reinstall the new carbon column. However, since the system only has one carbon column, the activated carbon purification system must be suspended during replacement and maintenance. This intermittent treatment method will affect the treatment efficiency of the entire purification system.

It should be understood that the specific embodiments described in this specification are only for the purpose of explaining the present invention and are not intended to limit the present invention.

[0030] It should also be understood that the terms used in this utility model specification are only for the purpose of describing specific embodiments and are not intended to limit the utility model. As used in this utility model specification and the appended claims, the singular forms "a", "an" and "the" are intended to include plural forms unless the context clearly indicates otherwise.

[0031] It should be further understood that the term “and / or” used in the present specification and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0032] In an embodiment of the present invention, an activated carbon column replacement mechanism 100 for sewage treatment is provided, which is used to replace or maintain the activated carbon column without stopping the machine by designing a dual activated carbon column structure, avoiding the problem of suspending the water purification system when replacing a traditional single carbon column, thereby improving the overall purification efficiency.

[0033] like Figure 1 and Figure 2 As shown, the activated carbon column replacement mechanism 100 for sewage treatment includes: a first carbon column 10 , a second carbon column 20 , a reversing valve seat 30 and a three-way pipe 40 .

[0034] A water inlet 33 and a first channel 31 and a second channel 32 respectively communicated with the water inlet 33 are defined in the reversing valve seat 30 .

[0035] One end of the first carbon column 10 is detachably connected to the reversing valve seat 30 and communicates with the first channel 31 ; one end of the second carbon column 20 is detachably connected to the reversing valve seat 30 and communicates with the second channel 32 .

[0036] Specifically, the reversing valve seat 30 defines a first retaining groove 34 and a second retaining groove 35. One end of the first carbon column 10 is engaged with the first retaining groove 34, and one end of the second carbon column 20 is engaged with the second retaining groove 35. Of course, internal threads may also be provided in the first retaining groove 34 and the second retaining groove 35, so that the first carbon column 10 and the second carbon column 20 can be detachably fixed to the bottom of the reversing valve seat 30 via a threaded connection.

[0037] Furthermore, a sealing ring 36 is provided at the bottom of the first slot 34 and the second slot 35. The first carbon column 10 presses the corresponding sealing ring 36 onto the bottom of the first slot 34, and the second carbon column 20 presses the corresponding sealing ring 36 onto the bottom of the second slot 35, so as to ensure the sealing performance when the first carbon column 10 and the second carbon column 20 are respectively connected to the reversing valve seat 30.

[0038] Furthermore, at least three latches 50 are provided on the outer walls of the first and second carbon pillars 10 and 20 on the side closest to the reversing valve seat 30, arranged in a circular array. The latches 50 are used to lock and securely engage with protrusions (not shown) on the reversing valve seat 30, thereby strengthening the connection between the first and second carbon pillars 10 and 20 and the reversing valve seat 30 and improving the security of the connection.

[0039] In the embodiment of the present invention, the three-way pipe 40 includes a first inlet end 41, a second inlet end 42, and a water outlet 43. The first inlet end 41 is connected to the outlet end of the first carbon column 10 away from the reversing valve seat 30, and the second inlet end 42 is connected to the outlet end of the second carbon column 20 away from the reversing valve seat 30, thereby forming two parallel water paths: one is connected through the water inlet 33, the first channel 31, the first carbon column 10, the first inlet end 41, and the water outlet 43; the other is connected through the water inlet 33, the second channel 32, the second carbon column 20, the second inlet end 42, and the water outlet 43.

[0040] A valve core 60 is located between the first channel 31 and the second channel 32. This valve core 60 switches the connection between the water inlet 33 and the first carbon column 10, or between the water inlet 33 and the second carbon column 20. The dual-carbon column design and the channel switching function of the valve core 60 allow for carbon column replacement or maintenance without shutting down the system, avoiding the need to suspend the purification system for traditional single-carbon column replacement, thereby improving overall purification efficiency.

[0041] Furthermore, the reversing valve seat 30 is provided with a drain port 37, which is located on either side of the valve core 60, along with the water inlet 33. The valve core 60 can be a conventional four-way valve structure, i.e., it has four through-holes and two internal passages. Thus, the valve core 60 is used to connect the water inlet 33 to the first passage 31 and the drain port 37 to the second passage 32, or to connect the water inlet 33 to the second passage 32 and the drain port 37 to the first passage 31.

[0042] The reversing valve seat 30 is rotatably mounted with a handle 38. The handle 38 may be a disc-shaped structure. The handle 38 is connected to the valve core 60 to drive the valve core 60 to rotate.

[0043] Specifically, a rotation hole 61 is formed in the center of the valve core 60, and a rotating shaft (not shown) is provided on the reversing valve seat 30 to be rotatably connected to the rotation hole 61. The handle 38 is coaxially connected to the rotating shaft. Therefore, the rotation hole 61 and the rotating shaft ensure that the valve core 60 rotates stably within the reversing valve seat 30.

[0044] Furthermore, a backwash connector 70 is provided on the side of the first carbon column 10 and the second carbon column 20 near the tee pipe 40. Therefore, backwash maintenance can be performed through the backwash connector 70 without disassembling the carbon columns, which facilitates maintenance. At the same time, the sewage is discharged through the sewage outlet 37, which facilitates centralized treatment and meets environmental protection requirements.

[0045] In one embodiment, the outlet end of the first carbon column 10 is provided with a first opening and closing valve 11, and the outlet end of the second carbon column 20 is provided with a second opening and closing valve 21. When changing the water flow path, the opening and closing valve can be used to close the outlet end of the carbon column to be maintained, thereby preventing the water purified from the carbon column from entering through the outlet end of another carbon column, and preventing the water from splashing through the outlet end into the three-way pipe 40 during backwashing. Secondly, by precisely controlling the water outlet status of each carbon column, the stable operation of the entire sewage treatment system can be ensured. In the event of an abnormal situation, the relevant valves can be quickly closed to cut off the source of the problem and prevent the fault from expanding. At the same time, the first opening and closing valve 11 and the second opening and closing valve 21 can also control the flow rate by the degree of opening and closing, thereby improving flexibility, and can also be closed in an emergency to improve safety.

[0046] In one embodiment, a plurality of positioning grooves 39 are provided in the reversing valve seat 30, and a positioning pin (not shown in the figure) is provided in the valve core 60. The positioning pin is used to cooperate with one of the positioning grooves 39 so that the valve core 60 can be switched to a predetermined position. The positioning groove 39 is provided with two water passage holes (not shown in the figure) connected to the water inlet 33. The cooperation between the positioning pin and the positioning groove 39 of the valve core 60 can ensure that the valve core 60 can be accurately switched to the predetermined position every time, avoiding system failures caused by human operation errors. At the same time, the design of the positioning pin and the positioning groove 39 effectively improves the stability of the valve core 60 during the switching process, reduces the position deviation caused by vibration or water flow impact, and thus ensures the accuracy of the waterway or sewage discharge path.

[0047] Therefore, during use, when one carbon column (such as the first carbon column 10) is in working condition and the other carbon column (such as the second carbon column 20) is in standby or maintenance condition, the valve core 60 in the reversing valve seat 30 is adjusted by the handle 38 to connect the water inlet 33 with the first channel 31, and the sewage outlet 37 with the second channel 32. At this time, sewage enters from the water inlet 33, is purified by the first carbon column 10, and then enters the tee pipe 40 from the outlet end of the first carbon column 10, and is finally discharged from the water outlet 43 of the tee pipe 40. The inlet end of the second carbon column 20 is closed, and the sewage outlet 37 is connected to the second carbon column 20 through the second channel 32. The backwash joint 70 can be used to backwash the second carbon column 20, or the second carbon column 20 can be disassembled from the second slot 35 of the reversing valve seat 30 for maintenance to achieve replacement of the carbon column.

[0048] In summary, the activated carbon column replacement mechanism 100 for sewage treatment provided by the utility model is to set a first channel 31 and a second channel 32 in the reversing valve seat 30, so that they are connected to the first carbon column 10 and the second carbon column 20 respectively, and then combine with the three-way pipe 40 to form two water channels, so that the water source of the water treatment and purification system can be switched to a certain water channel by rotating the valve core 60, and then the carbon column of the other water channel can be removed. The operation is simple and quick, which reduces the complexity and difficulty of manual operation, and there is no need to suspend the water treatment and purification system, thereby improving the overall purification efficiency.

[0049] The present invention is not limited to what is described in the specification and implementation modes, and therefore additional advantages and modifications can be easily realized by those skilled in the art. Therefore, without departing from the spirit and scope of the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details, representative devices, and illustrated examples shown and described herein.
