[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] Example 1

[0036] See also Figure 1-Figure 5 The utility model provides a technical solution: a purification column installation structure, including an upper end cover 2, a lower end cover 3, at least four purification columns arranged in a rectangular array between the upper end cover 2 and the lower end cover 3, and a fixing rod 4 for fixing the upper end cover 2 and the lower end cover 3.

[0037] The two ends of the fixing rod 4 are respectively fixedly connected to the center of the surface of the upper end cover 2 and the lower end cover 3 close to each other.

[0038] An upper mounting groove 21 is provided on one side of the upper end cover 2 close to the purification column 1, and a piston joint 22 is longitudinally movable in the upper mounting groove 21. The piston joint 22 has a piston tube 221 inserted into the upper end cover 2 and connected to the inlet end of the upper end cover 2. A spring 23 is respectively provided on the outside of the piston tube 221, and the two ends of the spring 23 are respectively connected to the upper mounting groove 21 and the piston joint 22. A through hole connected to the piston tube 221 is provided on the piston joint 22, and a lower mounting groove 31 connected to the outlet end of the lower end cover 3 is provided on one side of the lower end cover 3 close to the purification column 1.

[0039] When in use, since the fixing rod 4 fixes the upper end cover 2 and the lower end cover 3 together, the purification column 1 can be clamped more stably after installation to avoid loosening. When installing the purification column 1 between the upper end cover 2 and the lower end cover 3, it is only necessary to first press the top of the purification column 1 against the bottom of the piston joint 22 and squeeze it upward, so that the bottom end of the purification column 1 has space to move into the lower installation groove 31. When the bottom end of the purification column 1 moves above the lower installation groove 31, the upward force is stopped, so that the purification column 1 is pushed down by the piston joint 22 under the action of the spring 23, so that the two ends of the purification column 1 are respectively pressed between the upper end cover 2 and the lower end cover 3, thereby saving the time for assembling and disassembling the upper end cover 2 and the lower end cover 3, simplifying the steps, saving manpower, and being more efficient.

[0040] Among them, an elastic sealing gasket 32 ​​is arranged in the lower installation groove 31, and a through hole connected to the outlet end of the lower end cover 3 is opened on the elastic sealing gasket 32; by arranging the elastic sealing gasket 32 ​​in the lower installation groove 31, the elasticity of the elastic sealing gasket 32 ​​is utilized to press the bottom end of the purification column 1 and the lower end cover 3 tightly, so that the bottom end of the purification column 1 is more stable after being installed on the lower end cover 3, and the sealing performance is also better.

[0041] Example 2

[0042] Different from Example 1, Figure 4 and Figure 6 As shown, the upper end cover 2 has an inlet end corresponding to the inlet of each purification column 1 , and the lower end cover 3 has an outlet end corresponding to the outlet of each purification column 1 .

[0043] A water inlet mechanism 5 is arranged above the upper end cover 2, and the water inlet mechanism 5 includes a reversing valve 51 for controlling the connection direction to select different purification columns 1 for introduction, and an upper connecting pipe 52 installed between the outlet end of the reversing valve 51 and the inlet end of the upper end cover 2. The reversing valve 51 has an inlet end, and the number of outlet ends of the reversing valve 51 is the same as the number of purification columns 1.

[0044] A water outlet mechanism 6 is provided below the lower end cover 3, and the water outlet mechanism 6 includes a check valve 62 whose inlet end is fixedly installed at the outlet end of the lower end cover 3, a joint 61 provided below the lower end cover 3, and a lower connecting pipe 63 fixedly installed between the outlet end of the check valve 62 and the inlet end of the joint 61, wherein the joint 61 has an outlet end, and the number of inlet ends of the joint 61 is the same as the number of the purification column 1.

[0045] When the purification column 1 is disassembled and assembled, since the inlet end and outlet end corresponding to each purification column 1 are respectively provided on the upper end cover 2 and the lower end cover 3, each purification column 1 can work independently, so that the joint can be turned to other purification columns before disassembly and assembly, thereby maintaining continuous purification work. When a purification column 1 is disassembled, the reversing valve 51 can be used to turn the flow direction to the remaining inlet ends on the upper end cover 2, so as to replace the remaining purification columns 1 to maintain the purification work, thereby achieving uninterrupted purification supply. By providing a check valve 62 at the outlet end of each lower end cover 3, when any purification column 1 is disassembled, water leakage at the corresponding outlet end can be avoided, and only the outflow pipeline is maintained to enter the joint 61 and uniformly flow out through the outlet end of the joint 61.

[0046] Specifically, the reversing valve 51 includes a valve seat 511, a valve core 512 rotatably installed in the valve seat 511 and connected to the inlet end of the valve seat 511, a valve cover 513 fixedly installed at the end of the valve seat 511 away from the inlet end by bolts 514, and a handle 515 rotatably installed on the valve cover 513 and connected to the valve core 512, wherein a valve hole 516 is opened on the side of the valve core 512; when the reversing valve 51 is used, the valve core 512 is driven to rotate in the valve seat 511 by rotating the handle 515, so as to adjust the valve hole 516 on the valve core 512 to align with the target pipeline. During maintenance, it is only necessary to remove the bolts 514 to remove the valve cover 513 to expose the internal valve core 512 for maintenance.

[0047] Among them, a sealing sleeve 517 is provided between the valve seat 511 and the valve cover 513 and is sleeved on the outside of the valve core 512 rotating shaft. The end of the valve core 512 close to the inlet end of the valve seat 511 is provided with a sealing ring 518. The sealing sleeve 517 maintains the sealing between the valve seat 511 and the valve cover 513 to prevent water leakage during the switching operation. The sealing ring 518 maintains the sealing when the inlet end of the valve seat 511 is connected to the external water inlet pipe to prevent water leakage.

[0048] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
