[0019] Example 1

[0020] like Figures 1-4 As shown, the present embodiment proposes a large-scale water purification device capable of quickly replacing a filter assembly, comprising an upper filter frame 1, a lower filter frame 4 and a mounting frame 7. The top end of the upper filter frame 1 is connected to a connecting pipe 2, on which a control valve 3 is provided. An adjusting plate 13 is slidably provided on the upper filter frame 1; the top end of the lower filter frame 4 is connected to the upper filter frame 1, and a closing plate 9 is slidably provided on the lower filter frame 4. A spring b10 is provided between the closing plate 9 and the lower filter frame 4.

[0021] One mounting frame 7 is provided on each of the upper filter frame 1 and the lower filter frame 4. Multiple groups of lower closed components 8 are provided on both mounting frames 7. Multiple primary filter components are detachably connected on the upper filter frame 1 and the multiple groups of lower closed components 8. Multiple secondary filter components are detachably connected on the lower filter frame 4 and the multiple lower closed components 8. The number of primary filter components and secondary filter components is optimal in two groups, so that the equipment does not need to stop operating when replacing the primary filter component and the secondary filter component. When removing a single filter component, another filter component is used for filtering. The horizontal cross-section of the adjustment plate 13 is a hollow semicircle, and the adjustment plate 13 has a water inlet groove with an opening facing the connecting pipe 2.

[0022] The upper filter rack 1 includes a water-passing rack portion 101, a separation plate portion 102 and a flange portion a103 connected in sequence from top to bottom; the lower filter rack 4 includes a flange portion b41, an isolation plate portion 42 and a water outlet rack portion 43 connected in sequence from top to bottom; the flange portion a103 and the flange portion b41 are connected, and the upper filter rack 1 and the lower filter rack 4 are connected through the flange portion a103 and the flange portion b41. According to user needs, the user can add more filter racks between the upper filter rack 1 and the lower filter rack 4 to improve the water purification effect of the large-scale water purification equipment, and the isolation plate portion 42 and the separation plate portion 102 are rotatably provided with a clamping plate, which can clamp the filter assembly on the corresponding isolation plate portion 42 and the separation plate portion 102 to prevent the filter assembly from easily falling off the equipment.

[0023] When using this embodiment, the user places the corresponding primary filter assembly and secondary filter assembly on the device according to the needs of the water purifier. When the filter elements inside the primary filter assembly and the secondary filter assembly can no longer filter the water flow, the user holds the primary filter assembly and pushes the lower closing assembly 8 downward. At the same time, the spring c drives the adjustment plate 13 to descend until the adjustment plate 13 blocks the connection between the upper filter frame 1 and the primary filter assembly. The upper and lower ends of the primary filter assembly are respectively disengaged from the adjustment plate 13 and the lower closing assembly 8. The secondary filter assembly repeats the previous operation of removing the first filter assembly, so that the upper and lower ends of the secondary filter assembly are respectively disengaged from the closing plate 9 and the lower closing assembly 8, so as to avoid the user from quickly removing and replacing the filter assembly.

[0024] Example 2

[0025] like Figure 1 and Figure 3 As shown, this embodiment proposes a large-scale water purification equipment with a quickly removable filter assembly. Compared with the first embodiment, in this embodiment, the primary filter assembly includes a filter frame a5 whose upper and lower ends are respectively abutted against the upper filter frame 1 and the lower closing assembly 8, a filter element a6 arranged on the filter frame a5, and two limit frames arranged on the filter frame a5; the two limit frames are respectively located at the upper and lower ends of the filter frame a5, and the secondary filter assembly includes a filter frame b11 whose upper and lower ends are respectively abutted against the lower filter frame 4 and the lower closing assembly 8, and a filter element b12 arranged on the filter frame b11. The structures of the filter frame a5 and the filter frame b11 are the same, and the constituent materials of the filter element a6 and the filter element b12 are different, so the filtering effects of the filter element a6 and the filter element b12 are different.

[0026] When using this embodiment, the user performs secondary filtration on the water flow through the primary filter component and the secondary filter component, thereby improving the water purification effect of the equipment. The filter rack a5 and the filter rack b11 with the same structure can reduce the mold opening cost of the equipment and reduce the maintenance cost of the equipment.

[0027] Example 3

[0028] like Figure 2-Figure 4 As shown, this embodiment proposes a large-scale water purification device capable of quickly replacing a filter assembly. Compared to the first embodiment, in this embodiment, the lower sealing assembly 8 includes an abutment frame 83 slidably mounted on the mounting frame 7, an inclined frame 81 mounted on the abutment frame 83, a sealing gasket 82 mounted on the top of the inclined frame 81, a threaded column 84 mounted on the abutment frame 83, a nut 85 threadedly connected to the threaded column 84, and a spring a86 with its ends respectively abutting the nut 85 and the mounting frame 7. The horizontal area of ​​the inclined frame 81 increases as the distance from the ground gradually decreases.

[0029] When this embodiment is in use, the filter rack a5 or the filter rack b11 is placed on the sealing gasket 82. The filter rack a5 or the filter rack b11 pushes the abutment rack 83 downward through the sealing gasket 82, so that the top of the filter rack a5 has enough space to contact the upper filter rack 1. When the user lets go, the spring a86 drives the nut 85 to drive the threaded column 84 to reset the abutment rack 83, so that the abutment rack 83 and the upper filter rack 1 fix the primary filter assembly, thereby ensuring that the device can be portable and the filter assembly can be replaced.

[0030] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
