People familiar with the technology can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Combined with reference Figure 1-Figure 5The utility model provides an activated carbon composite filter element, including a fixed plate 1, a plurality of split barrel covers 2 are vertically fixedly connected to the side of the fixed plate 1, a filtering interval is reserved between two adjacent split barrel covers 2, a top sealing plate 3 is fixedly connected to the top of the split barrel cover 2 located at the top, and a bottom sealing plate 4 is fixedly connected to the bottom of the split barrel cover 2 located at the bottom, a mounting mesh frame 5 is tightly arranged in the filtering interval, and an activated carbon filter screen 6 is fixedly connected in the mounting mesh frame 5, and activated carbon filter screens 6 of different filtering specifications are arranged between multiple split barrel covers 2, so that the entire activated carbon composite filter element can have a multi-stage composite filtering effect, and the outer surface of the mounting mesh frame 5 is fixedly connected to a positioning block 7 that cooperates with the fixed plate 1 for plugging, and the positioning block 7 can provide plug-in positioning for the mounting mesh frame 5 to be arranged in the filtering interval, and a pair of telescopic tensioning components 8 are fixedly connected to the outer surfaces of the top sealing plate 3 and the bottom sealing plate 4.

[0025] A connecting pipe 10 is fixedly passed through the top sealing plate 3 and the bottom sealing plate 4. A pair of connecting pipes 10 can be used as a water inlet end and a water outlet end. The water to be purified is fed into the water through the connecting pipe 10 at the water inlet end, and the water can be discharged from the connecting pipe 10 at the water outlet end after passing through the activated carbon filter 6.

[0026] Both side end faces of the installation net frame 5 are fixedly connected with sealing gaskets 12, which fit tightly in the filtering interval. The installation net frame 5 can be slid into between two adjacent split cylinder covers 2 through the sealing gaskets 12. While facilitating the installation, the sealing gaskets 12 can increase the sealing performance of the connection between the installation net frame 5 and the split cylinder covers 2.

[0027] The outer surface of the installation net frame 5 is rotatably connected with a pull ring 11, and the pull ring 11 can be rotatably connected to the installation net frame 5 through a hinge seat. The pull ring 11 can be folded and arranged on the installation net frame 5, and the pull ring 11 can facilitate pulling the installation net frame 5.

[0028] Each telescopic tensioning assembly 8 includes a pair of fixed blocks 81, an annular sliding column 82 fixedly connected to the pair of fixed blocks 81, a sliding seat 83 slidably connected to the annular sliding column 82, and a return spring 84 sleeved on the annular sliding column 82. A vertically arranged pair of sliding seats 83 are fixedly connected to a column 9, and an extrusion plate 91 is fixedly connected to the column 9. The extrusion plate 91 is in pressure contact with the outer surface of the mounting frame 5.

[0029] A damping pad 14 is fixedly connected to one side of the fixed block 81 facing the slide 83. When the slide 83 rebounds and resets through the reset spring 84, the damping pad 14 can reduce the impact force of the contact between the slide 83 and the fixed block 81 to achieve the effect of damping and vibration reduction.

[0030] Specifically, when it is necessary to install the installation frame 5 with the activated carbon filter 6, the installation frame 5 can squeeze a pair of columns 9, so that the column 9 can slide on the annular slide column 82 around the center position of the split tube cover 2 through a slide seat 83. At this time, the reset spring 84 is in a compressed state until the opening and closing degree of the pair of columns 9 meets the requirement of the installation frame 5 entering the filtering interval. In this way, the installation frame 5 can be inserted into the fixed plate 1 through the positioning block 7 and tightly arranged between the adjacent split tube covers 2. In this process, the slide seat 83 can be rebounded and reset by the tensioning force of the reset spring 84, so that the pair of columns 9 can drive the corresponding extrusion plate 91 to be tightly attached to the arc surface of the installation frame 5. By providing two-point support, when there is no external force acting on the pull ring 11, the installation frame 5 can carry the activated carbon filter 6 for stable filtration between the split tube covers 2.

[0031] Similarly, by pulling the pull ring 11, the installation screen frame 5 can squeeze the pair of columns 9, and the pair of columns 9 gradually open and close to provide an interval for taking out the installation screen frame 5.

[0032] A pair of auxiliary support assemblies 13 are fixedly connected to the outer surface of one of the split barrel covers 2, and each auxiliary support assembly 13 includes a pair of fixed blocks 131, an annular sliding column 132 fixedly connected to the pair of fixed blocks 131, and a slide seat 133 slidably connected to the annular sliding column 132. The column 9 is fixedly connected to the slide seat 133. In the present application, when the column 9 is fixed on the slide seat 133, it can be a two-section structure. When the column 9 moves based on a circular path, the slide seat 133 can slide on the annular sliding column 132, so that the slide seat 133 can increase the supporting strength of the column 9.

[0033] A water pressure detection device 15 for sensing liquid pressure is provided in each split barrel cover 2, and a water pressure display screen 16 for displaying detection data of the water pressure detection device 15 is provided on the outer surface of each split barrel cover 2. Both the water pressure detection device 15 and the water pressure display screen 16 can be connected to an external controller for data processing. The water pressure detection device 15 can be used to sense the liquid pressure at the inlet and outlet positions of the activated carbon filter 6. By obtaining the data difference of the liquid pressure, the permeability state of the activated carbon filter 6 filtering the liquid, that is, the blockage state, can be known.
