5. The residual acid collecting system for lead-acid battery production according to claim 1, characterized in that the residual acid collecting system comprises the following steps:
the method comprises the following steps: during acid pumping, a vacuum acid and alkali resistant pump (10) is started for vacuum pumping, a one-way valve (8) on an acid liquor inlet pipe (6) is started, the one-way valve (8) on an acid liquor outlet pipe (11) is closed, an acid pumping pipe (2), a temporary acid pumping storage tank (1) and an acid liquor deposition pipe (3) form a passage, meanwhile, an acid adding machine (4) is started, and acid liquor in the acid liquor deposition pipe (3) flows into a formation tank of a lead-acid storage battery through a first acid outlet pipe (5);
step two: after the acid pumping is finished, a vacuum acid and alkali resistant pump (10) is closed for vacuum pumping, a one-way valve (8) on an acid liquor inlet pipe (6) is closed, an acid liquor outlet pipe (11) and the one-way valve (8) on a connecting pipe (17) are opened, acid liquor in a temporary acid pumping storage tank (1) and an acid liquor deposition pipe (3) flows into a filter cylinder (16) through the connecting pipe (17), an upper-layer filtering steel mesh screen (21), a lower-layer filtering cloth bag (23) and a leakage hopper (22) are installed inside the filter cylinder (16), the upper-layer filtering steel mesh screen (21) firstly performs primary filtering on the acid liquor, the primarily filtered acid liquor falls to the lower-layer filtering cloth bag (23) through the leakage hopper (22), the lower-layer filtering cloth bag (23) performs secondary filtering on the acid liquor, and the filtered acid liquor continuously flows into a collection cylinder (15);
step three: when the liquid level of the acid liquid in the collecting cylinder (15) rises continuously, the acid liquid enters the movable cavity (28) through the through hole (31) and the through hole (30), and under the influence of buoyancy, the continuously rising liquid level of the acid liquid drives the buoyancy ball (29) to move from bottom to top in the movable cavity (28) until the buoyancy ball (29) touches the touch switch (27) on the upper side of the inner wall of the movable cavity (28), the touch switch (27) is turned on, the circuit between the acousto-optic alarm (32) and the power supply is communicated, and the acousto-optic alarm (32) works to emit acousto-optic sound;
step four: when the acousto-optic alarm (32) emits acousto-optic sound, a worker timely knows that the acid liquor in the collecting cylinder (15) is enough in capacity, a one-way valve (8) on a connecting pipe (17) between the collecting cylinder (15) and the precipitating cylinder (14) is opened, the acid liquor flows into the precipitating cylinder (14) through the connecting pipe (17), the acid liquor is kept still and precipitated in the precipitating cylinder (14), when supernatant liquid reaches the upper part of the acid liquor, the one-way valve (8) on the connecting pipe (17) between the precipitating cylinder (14) and the recovering cylinder (12) is opened, the supernatant liquid flows into the recovering cylinder (12), when the acid liquor is used, the one-way valve (8) on the second acid outlet pipe (13) is opened, and the acid liquor flows into a formation tank of the battery again.
