[0025] Preferably, the system further comprises a safety valve 16 arranged at the top end of the filter tank body 1.

[0026] The working process of the system is as follows:

[0027] 1. The reused water enters the first and second coil pipes through the water inlet main pipe and the first and second water inlet branch pipes, and the water jet nozzles of the first and second coil pipes spray the reused water to the multi-medium filter materials in the filter material cavity through the pagoda-shaped filter caps, and then the reused water filtered by the multi-medium filter materials enters the clean water cavity through the filter plates, and then the clean reused water is provided to the production system through the water outlet pipe.

[0028] 2. When the pressure gauge of the first water inlet branch pipe shows normal pressure and the water outlet flow of the water outlet pipe flow meter is lower than the set value, the water outlet pipe flow meter sends a related signal to the controller, the controller outputs a signal to close the electric valve of the first water inlet branch pipe (at this time, the first water inlet branch pipe has no water), and at the same time, sends an opening instruction to the pneumatic valve of the first compressed air branch pipe, and the compressed air enters the water inlet pipeline through the first compressed air branch pipe to input intermittent high-pressure compressed air, and the oil stains or small impurities are flushed out through the waist-shaped spray holes of the pagoda-shaped filter cap, and at the same time, the hard plastic wear-resistant balls perform violent impact action in the inner cavity of the pagoda-shaped filter cap, which also plays a role in cleaning and dredging the inner cavity and waist-shaped spray holes of the pagoda-shaped filter cap, and realizes online scale removal and dredging of the first coil pipe and the pagoda-shaped filter cap.

[0029] 3. At the same time, the controller sends an opening instruction to the electric valve of the second water inlet branch pipe, and the reused water quickly enters the second water inlet branch pipe and the second coil pipe, and is sprayed to the multi-medium filter materials in the filter material cavity through the pagoda-shaped filter cap of the second coil pipe, so that the equipment can normally run and filter, and the production system can use water.

[0030] 4、When the pressure gauge of the second water inlet branch shows normal pressure, and the water outlet flow of the water outlet flowmeter is lower than the set value, the water outlet flowmeter sends an associated signal to the controller, which sends a closing command to the electric valve of the second water inlet branch (at this time the second water inlet branch has no water), and at the same time sends an opening command to the pneumatic valve of the second compressed air branch, and the compressed air is input into the water inlet pipeline through the second compressed air branch to perform intermittent high-pressure compressed air flushing and cleaning of the second coil and the pagoda-shaped filter cap. The oil stains or small impurities are flushed out through the waist-shaped spray holes of the pagoda-shaped filter cap, and at the same time the hard plastic wear-resistant balls perform violent impact action in the pagoda-shaped filter cap, which also plays a role in cleaning and clearing the inner cavity and waist-shaped spray holes of the pagoda-shaped filter cap, realizing online cleaning and clearing of the second coil and the pagoda-shaped filter cap.

[0031] 5、At the same time, the controller sends an opening command to the electric valve of the first water inlet branch, and water quickly enters the first water inlet branch and the first coil, and is sprayed to the multi-media filter material in the filter material cavity through the pagoda-shaped filter cap of the first coil, so that the equipment can perform normal filtering operation and ensure the production system water.

[0032] 6、During normal operation of the system, due to the pressure fluctuation of the reused water entering the first coil and the second coil through the water inlet main pipe and the first water inlet branch and the second water inlet branch, the hard plastic wear-resistant balls in the inner cavity of the pagoda-shaped filter cap also perform impact action in the inner cavity of the pagoda-shaped filter cap, which can clean and clear the dirt adhered to the inner cavity of the pagoda-shaped filter cap and the waist-shaped spray holes in real time, and ensure that the waist-shaped spray holes of the pagoda-shaped filter cap remain unblocked.

[0033] The system is designed and installed with two water inlet pipelines inside and outside the multi-media filter tank, ensuring that the water inlet system is in a one-back-up state. Two compressed air automatic flushing and cleaning pipelines are installed in the two water inlet branches outside the multi-media filter tank, ensuring that the two water inlet pipelines are in a smooth working state. At the same time, the pagoda-shaped filter cap with self-cleaning function is installed at the end of the coil in the multi-media filter tank, realizing intelligent online automatic cleaning and clearing function. In a high-efficiency and automatic way, the problem of multi-media filter water inlet pipeline blockage is solved, ensuring the supply of reused water for the production system and avoiding the failure of the production system.
