The working principle and the using process of the invention are as follows: when the stirring device is used, firstly, solution and active carbon are added into the stirring box 1, the active carbon is impregnated, the rotating rod 4 is driven to rotate anticlockwise by turning on a switch of the motor 3, so that the first stirring blade 5 is driven to rotate, the solution in the inner cavity of the stirring box 1 can be stirred, the rotating rod 4 drives the annular lifting plate 10 to rotate, so that the gear rod 11 is driven to rotate, the gear rod 11 can contact and drive the lower moving block 24 to move backwards for a certain distance every time the gear rod 11 rotates for one circle, when the gear rod 11 is separated from the moving block 24, the moving block 24 and the sliding block 15 can reset under the driving of the first spring 16, the lower moving block 24 moves backwards for a certain distance and resets, the ejector rod 17 can be driven to move backwards for a certain distance and reset, the ejector rod 17 touches the rotating plate 22 to rotate for a certain distance, then the rotating plate 22 resets under the action of the second spring 23, so that the curved rod 20 drives the rotating disc 18 to rotate in a reciprocating manner, thereby driving the second stirring blade 19 to rotate back and forth to stir the bottom of the solution, improving the stirring efficiency while the first stirring blade 5 is stirring the solution counterclockwise, and further improving the reaction rate, when other solutions need to be added slowly, only by putting the solution into the solution barrel 27, under the condition that the upper part of the gear lever 11 is not blocked, the threaded rod 7 is driven to rotate by rotating the knob 8, thereby driving the annular lifting plate 10 to move upwards, so that the gear lever 11 moves upwards, when the gear lever 11 moves to be in contact with the upper moving block 24, the gear lever 11 is driven to rotate by opening the motor 3, the gear lever 11 rotates a circle, and likewise, the upper moving block 24 is driven to move backwards for a certain distance and reset, thereby driving the moving rod 25 and the sealing plug 26 to move the same as the upper moving block 24, when the sealing plug 26 is separated from the inner side of the through hole 28, the solution in the solution barrel 27 flows out, when the sealing plug 26 is reset, the through hole 28 is completely blocked, the solution does not flow out at this time, the flowing solution enters the feeding hopper 30 and then enters the inner cavity of the stirring box 1 through the connecting pipe 29 to be added into the reacting solution, and a small amount of other solution can be added into the inner cavity of the stirring box 1 to react every turn of the blocking rod 11, so that the slow adding effect is formed.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
