[0026] In the above embodiment, the opening and closing states of valve a, valve b and the retainer 23 correspond to three working modes:

[0027] Mode 1, energy storage process: When valve b is in the closed state and the retainer 23 is in the locked state, the water pump is started to make the pressure plate 22 squeeze the airbag 24;

[0028] Mode 2, backwash filter plate: After the energy storage in mode 1 is completed, the holder 23 is opened, and the release plate 21 slides upward under pressure in the filter box 11, causing the water flow in the filter box 11 to backwash the filter plate 12;

[0029] Mode 3, flushing equipment pipelines: After the energy storage in mode 1 is completed, open valve b, and the pressure plate 22 drives the water flow to flush the water pipelines of the mud production water equipment.

[0030] The circulating water energy-saving system for cement production in this application can utilize the energy of the water pump and combine it with the energy storage component to complete the flushing of relevant water pipes and filter plates of the filter component without adding excessive additional energy-consuming equipment, so as to prevent scaling and dirt from affecting the water circulation efficiency and achieve the purpose of energy saving.

[0032] In one embodiment of the present application, preferably, an airbag tube cavity 13d connected to the passage 13e is provided on the base 13, and a sliding ring 251 is provided at the bottom end of the airbag tube 25. The sliding ring 251 can slide in the airbag tube cavity 13d, and the locking tongue of the fixer 23 can be embedded in the groove 252 provided on the sliding ring 251.

[0036] In one embodiment of the present application, preferably, a sewage storage chamber 14 is provided on the filter box 11, and the sewage storage chamber 14 is fixedly arranged on the side wall of the filter box 11. The upper surface of the filter plate 12 is flush with the entrance of the sewage storage chamber 14, and the horizontal height of one end of the filter plate 12 connected to the sewage storage chamber 14 is lower than the other opposite end; in this way, when the sewage passes through the filter plate 11, large particles of debris therein will fall into the sewage storage chamber 14 due to the inclined setting of the filter plate 12, or the dirt washed during the backflushing process of the filter plate 12 can fall into the sewage storage chamber 14, so as to facilitate the staff to clean the dirt.

[0037] In one embodiment of the present application, preferably, a flushing groove 12d is provided at one end of the filter plate 12 away from the sewage storage chamber 14, and the flushing groove 12d is a through groove on the filter plate 12; a flushing plate 111 is fixedly provided on the inner wall of the filter box 11 on the upper side of the flushing groove 12d, and the flushing plate 111 is parallel to the filter plate 12.

[0039] In one embodiment of the present application, preferably, the aperture of the bottom end of the filter hole 12e is larger than the aperture of the top end thereof, so as to facilitate the backwash water flow to enter the filter hole 12e and to gather stronger water flow pressure to improve the efficiency of backwash cleaning.

[0040] In one embodiment of the present application, preferably, multiple groups of filter plates 12, sewage storage chambers 14 and flushing plates 111 are arranged in the filter box 11 to improve the filtering effect; the aperture of the filter hole 12e of the filter plate 12 away from the base 13 is smaller than the aperture of the filter hole 12e of the filter plate 12 close to the base 13, that is, the farther away from the base 12, the larger the aperture of the filter hole 12e on the filter plate 12, so as to achieve the purpose of graded filtration.
