[0026] 2. Structure assembly of the tank stirring mechanism and operation control method:
[0027] In order to save energy and facilitate operation, the utility model adopts two 11-kilowatt three-phase six-stage motors to drive the stirring block, as shown in Figure 11 , which realizes the use of two motors to drive the stirring blocks in four tanks. The operation steps are divided into two steps:
[0028] First, when the motor rotates, it drives the transmission shaft to rotate through the gear and chain. The transmission shaft rotates, and the rope winding device connected to the shaft rotates. The hollow rope winding shaft rotates to wind the traction rope (steel wire rope) on the hollow rope winding shaft. As the traction rope is wound on the hollow rope winding shaft, the stirring block at the end of the traction rope is pulled to one side of the rope winding device, the power is turned off, and the motor stops;
[0029] Second, another motor installed at the opposite end, like the first step, pulls the stirring block back to the opposite side of the rope winding device. This back and forth pulling makes the stirring block move back and forth between the two ends of the tank, and the organic matter deposited at the bottom of the tank can be uniformly stirred with the upper layer of wastewater.
[0030] III. Loading mechanism:
[0031] The water and fertilizer loading mechanism comprises a submersible pump, a submersible pump mounting bracket, and a fertilizer loading pipe.
[0032] The submersible pump mounting bracket is installed at the bottom of the fertilizer storage tank, the discharge port of the submersible pump is connected to the fertilizer loading pipe, and the submersible pump is started to pump the water and fertilizer into the fertilizer applicator through the fertilizer loading pipe.
