[0031] The mixing assembly 2 includes a lifting frame 201 and electric push rods 202 installed at the edges of both sides of the bottom thereof. A support plate 203 is fixedly connected to one side of the upper surface of the lifting frame 201. A motor 204 is installed on one side of the top of the support plate 203. The height position of the lifting frame 201 can be adjusted under the action of the electric push rods 202.

[0032] A buffer mechanism 103 is evenly spaced between the bottom of the reaction pool 102 and the inner bottom of the box 1, and a spray mechanism 104 is provided on one side of the bottom of the box 1. The buffer mechanism 103 and the spray mechanism 104 are both prior arts, so they will not be described in detail here.

[0033] The output shaft of the motor 204 passes through the bearing on one side of the upper surface of the support plate 203 and is connected to the first rotating shaft 2041 through a coupling. The other end of the first rotating shaft 2041 passes through the center position of the upper surface of the first belt pulley 2042 and is connected to the first toothed disc 2043. The first belt pulley 2042 and the first toothed disc 2043 are both located on the first rotating shaft 2041, and the three can move synchronously.

[0034] One side of the outer wall of the first pulley 2042 is connected to the second pulley 2051 through a belt, and a second rotating shaft 205 is installed at the bottom center of the second pulley 2051. A second toothed disc 2061 is arranged on one side of the first toothed disc 2043. The first pulley 2042 and the second pulley 2051 are connected through a belt to play a transmission role. The gear on the outer wall of the first toothed disc 2043 is meshed with the gear on the outer wall of the second toothed disc 2061 to play a transmission role.

[0035] A hollow rotating rod 206 is installed at the center of the inner wall of the second gear disc 2061.

The first stirring rods 2052 and the second stirring rods 2063 are alternately arranged up and down.

[0037] When the above arrangement is in use, the crushed slag is first put into the reaction tank 102, and then the reaction solution and water are sprayed into the reaction tank 102 through the spraying mechanism 104, and then the electric push rod 202 is started, and the telescopic end of the electric push rod 202 is contracted to extend the mixing assembly 2 into the reaction tank 102, and then the motor 204 is started, and the output shaft of the motor 204 rotates to drive the first rotating shaft 2041 to rotate through the coupling, and the rotation of the first rotating shaft 2041 will drive the first pulley 2042 and the first toothed disc 2043 on its outer wall to rotate, wherein the outer wall of the first pulley 2042 is connected to the second pulley 2051 through a belt, and the gear on the outer wall of the first toothed disc 2043 is meshed with the gear on the outer wall of the second toothed disc 2061.

Under the action of the slide plates 3021 and the slide grooves 3011, the installation frame 302 can be quickly pulled out, and the filter screen 303 inside can be disassembled and replaced;

[0040] When the above arrangement is in use, when the reaction solution sprayed by the spraying mechanism 104 is large, it will overflow from the inside of the reaction pool 102 into the inside of the box body 1, and then the solution inside the box body 1 will flow into the inside of the filter box 301 through the liquid outlet pipe 101. After the solution is filtered through multiple filter screens 303 inside the filter box 301, it is re-drawn by the spraying mechanism 104 and sprayed into the inside of the reaction pool 102, which can avoid the waste of the reaction solution. At the same time, after the filter screen 303 is used for a long time, the installation frame 302 is pulled outward, and the installation frame 302 slides out under the action of the slide plate 3021 and the slide groove 3011. Then, the filter screen 303 inside the installation frame 302 can be replaced and cleaned, which can avoid the residue in the solution from entering the inside of the equipment, affecting the service life of the equipment, and causing damage to the equipment. It is also convenient for quick disassembly and replacement of the filter screen 303, and the work efficiency is high.
