Technical Field

[0001] The invention belongs to the technical field of purification and filtration, and in particular relates to an activated carbon filtration system for purifying drinking water. Background Art

[0009] Preferably, a plurality of evenly distributed resistance-reducing balls are movably embedded in the sides of the two assembly plates, and the resistance-reducing balls roll and abut against the inner wall of the activated carbon filter shell. A plurality of drainage holes are provided on the top of the upper assembly plate and the top of the activated carbon filter shell, and the lower ends of the drainage holes are interconnected with the gap between two adjacent detachable annular activated carbon plates.

[0010] Preferably, a sewage collecting assembly is fixedly connected to the top of the activated carbon filter shell, the water collecting pipe is movably arranged inside the sewage collecting assembly, the lower end of the sewage collecting assembly is connected to the gap between several detachable annular activated carbon plates through a sewage discharge hole, and the upper end of the sewage collecting assembly is fixedly connected to a manual sewage discharge valve.

[0014] Preferably, the following steps are included:

[0015] S1. Clean water enters through the water inlet pipe, passes through the check valve, adapter pipe and connecting pipe, enters the interior of the activated carbon filter shell, and impacts the detachable plate-shaped activated carbon plate;

[0016] S2. Under the restriction of the outlet pipe and the assembly plate, the detachable plate-shaped activated carbon plate impacted by the water flow drives the two assembly plates and the several detachable annular activated carbon plates and detachable plate-shaped activated carbon plates between the two to continuously rotate around the outer surface of the outlet pipe;

[0017] S3. When the detachable annular activated carbon plate and the detachable plate-shaped activated carbon plate rotate continuously, the activated carbon cloth coated on the outer surface thereof quickly contacts the water flow, thereby absorbing impurities in the clean water;

[0018] S4. The clean water is purified by the activated carbon cloth on the surface of the detachable ring-shaped activated carbon plate and the detachable plate-shaped activated carbon plate, and then enters the interior of the water collecting pipe through the detachable filter membrane and the support frame and is discharged;

[0019] S5. When the water flow increases, the detachable plate-shaped activated carbon plate is quickly pushed to make the several detachable ring-shaped activated carbon plates and the detachable plate-shaped activated carbon plates between the two assembly plates rotate rapidly, further improving the efficiency of contact between the activated carbon cloth and the impurities in the clean water;

[0020] S6. After a certain period of time, close the water collecting pipe to stop the water discharge, open the manual drain valve at the same time, and then inject high-speed water flow through the water inlet assembly;

[0021] S7. The high-speed water flow pushes the detachable plate-shaped activated carbon plate, causing the assembled plate and the detachable ring-shaped activated carbon plate to rotate rapidly as a whole. When a sufficient rotation speed is reached, the impurities adsorbed on the surface of the activated carbon cloth obtain sufficient centrifugal force, thereby causing the adsorbed impurities to separate from the activated carbon cloth and follow the water flow through the drain hole into the interior of the buffer sewage collection chamber, and finally be discharged by the manual drain valve.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. Due to the provision of the detachable plate-like activated carbon plate, the present invention enables a plurality of detachable plate-like activated carbon plates and a detachable ring-like activated carbon plate to rotate continuously as a whole under the cooperation of the assembly plate, the water outlet pipe and the water inlet assembly, so that the clean water entering the water inlet assembly can fully contact with the detachable ring-like activated carbon plate and the activated carbon cloth on the outer surface of the detachable ring-like activated carbon plate before entering the water outlet pipe, thereby effectively improving the adsorption efficiency.

[0024] 2. Due to the provision of the detachable filter membrane of the present invention, it can be removed from the outside of the support frame with the cooperation of the Velcro at both ends for thorough cleaning or replacement. Similarly, it is also convenient to thoroughly clean or replace the activated carbon cloth outside the detachable annular activated carbon plate and the detachable plate-shaped activated carbon plate.

[0025] 3. Due to the setting of the eccentric sewage collecting cover, the present invention can facilitate the centralized discharge of activated carbon cloth sewage cleaned by high-speed centrifugal cleaning with the cooperation of the sewage discharge hole and the manual sewage discharge valve. Moreover, the inner wall of the internal buffer sewage collecting chamber is inclined, which can provide a slope buffer for the high-speed water flow, reduce the impact of the water flow on the sewage collecting component and the manual sewage discharge valve, and reduce the damage rate of the sewage collecting component and the manual sewage discharge valve.

[0046] like Figure 8 As shown, the detachable filter membrane 33 is a strip structure, and Velcro is provided at both ends of the detachable filter membrane 33.

[0048] like Figures 1 to 11 As shown, the following steps are included:

[0049] S1. Clean water enters through the water inlet pipe 22, passes through the check valve 24, the adapter pipe 23 and the connecting pipe 21, enters the interior of the activated carbon filter housing 1, and impacts the removable plate-shaped activated carbon plate 6;

[0050] S2.
