when in use, heated and cooled liquid is added into an outer tank (23) fixed on a support (1) from a liquid inlet pipe (21), then the liquid is discharged through a liquid outlet pipe (22), a pipe cover (41) is opened, water is injected into an inner tank (31) from an injection pipe (42), a cover (71) is opened, a substance needing hydrolysis is injected from a pipeline (72), a power supply is switched on, a motor (51) arranged on a fixed shell (52) starts to rotate so as to drive a long rod (55) sleeved on a connecting block (53) to rotate, the long rod (55) is further fixed by a fixed block (54), so that a fan blade (56) fixed on the long rod (55) rotates, the water in the inner tank (31) and the substance needing hydrolysis are stirred, the hydrolysis reaction of the substance is accelerated, when the reaction is complete, the liquid in the liquid inlet pipe (21) is stopped, and when the liquid in the liquid outlet pipe (22) is completely discharged, then the liquid discharge cover (24) is opened, then the liquid in the outer tank (23) is completely discharged, then the handle (33) is pinched, the plug (32) is opened, then the liquid in the inner tank (31) is discharged, the liquid is collected, after the liquid is discharged, the plug (32) is covered in the inner tank (31), the liquid discharge cover (24) is installed in the outer tank (23), then clear water is injected from the injection pipe (42) and the pipeline (72), the motor (51) installed on the fixed shell (52) starts to rotate, so that the long rod (55) sleeved on the connecting block (53) is driven to rotate, the fixed block (54) further fixes the long rod (55), so that the fan blades (56) fixed on the long rod (55) rotate, the clear water in the inner tank (31) is stirred, so that the inner wall of the inner tank (31) is cleaned, and the next reaction is prevented because of the residue on the inner wall of the inner tank (31), the liquid in the next reaction is polluted, but the liquid in the pipeline (72) is in a standing state and cannot be influenced by stirring of the fan blades (56), then the long rod (55) on the connecting block (53) is taken out, the block (93) is vertically placed in the inlet of the pipeline (72), the block (93) is sent to the other end of the pipeline (72) by utilizing the connecting column (85), then the rope (92) is pulled to transversely place the block (93) so as to block the block (93) at the bottom end of the pipeline (72), then the redundant rope (92) is wound in the roller (91) and the rope (92) is clamped in the clamping groove on the roller (91), the clamping block (83) is clamped on the fixing plate (61), then the handle (81) is pulled, the steel wire (86) connected on the circular ring (82) connected with the handle (81) drives the sliding block (87) and the brush (88) to slide on the connecting column (85), and the spring (84) is compressed, so that the brush (88) brushes the inner wall of the pipeline (72), when the handle (81) is released, the spring (84) is released, the sliding block (87) and the brush (88) move to the position away from the clamping block (83), the handle (81) is pulled back and forth and released, and the brush (88) brushes the inner wall of the pipeline (72) back and forth, so that the interior of the pipeline (72) is cleaned, and the liquid of the next reaction is prevented from being influenced by the residue of the object of the previous reaction.
