In addition, the terms "first", "second" and "third" are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0020] The specific embodiment of the utility model: the environmental protection type activated carbon deep processing mixing device, including mixing container 1, adopt cylindrical stainless steel material, have good corrosion resistance and strength, can bear various forces in the mixing process;The mixing container 1 top is equipped with the sealing cover 11 that can open, it is convenient to add activated carbon raw materials and additive, prevent activated carbon splashing in the mixing process simultaneously, the mixing container 1 bottom is provided with discharge port 12, the discharge port 12 is provided with solenoid valve, and the discharge is controlled through valve. Mixing container 1 inside is provided with the stirring structure of stirring mixing activated carbon.

[0021] As the invention point of the utility model:

[0022] The stirring structure includes stirring shaft 2 and screw conveyor 3, the stirring shaft 2 is arranged in the vertical direction in the inside center position of mixing container 1;The top end of the stirring shaft 2 is arranged in the top wall of mixing container 1, and is connected with the first drive motor 22 through the shaft coupling. The stirring shaft 2 is made of high-strength alloy steel, has sufficient strength and rigidity, and can withstand the torque and bending moment in the stirring process.

[0023] As preferred, the shaft arm of the stirring shaft 2 is provided with a plurality of stirring blades 21 for disturbing the mixing state of activated carbon, which includes horizontal stirring blades 211 arranged in a horizontal posture or close to a horizontal posture, and inclined stirring blades 212 arranged at a certain angle with the horizontal direction, wherein the inclined stirring blades 212 include upwardly inclined blades and downwardly inclined blades.

[0024] The stirring shaft 2 is provided with a spiral conveying device 3 on one side, the spiral conveying device 3 comprises spiral blades 31 and a central shaft 32, the central shaft 32 is arranged in parallel with the stirring shaft 2, the spiral blades 31 are distributed in a spiral around the central shaft 32, and the spiral blades 31 and the central shaft 32 are connected in a detachable manner through welding, screw connection or other connection modes; one end of the central shaft 32 is rotationally connected with the bottom wall of the mixing container 1 through a bearing seat, the other end penetrates the top wall of the mixing container 1 and extends to the outside of the mixing container 1 and is connected with a second driving motor 33 through a shaft coupling.

[0025] As preferred, the spiral blades 31 are arranged in a gap close to the inner wall of the mixing container 1, and the gap between the spiral blades 31 and the inner wall of the mixing container 1 is 5-10 mm; in this way, the activated carbon can be smoothly conveyed upward along the wall of the mixing container 1 under the pushing of the spiral blades 31, the wall of the mixing container 1 restricts and rubs to generate radial and circumferential movement, and the activated carbon flow in the central area driven by the stirring shaft 2 forms a convection, thereby improving the mixing uniformity; if the gap is too small, the activated carbon is prone to be blocked in the gap, which hinders the conveying process and reduces the mixing efficiency; if the gap is too large, the activated carbon close to the wall of the mixing container 1 is difficult to be effectively grabbed and conveyed by the spiral blades 31, and part of the activated carbon is retained at the bottom or near the wall of the mixing container 1, so that the activated carbon cannot fully participate in the mixing circulation.

[0026] The spiral blades 31 and the central shaft 32 are made of stainless steel, which can adapt to the corrosion and wear of the equipment by the activated carbon during the mixing process of the activated carbon, and ensure the long-term stable operation of the equipment.

[0027] It should be noted that the utility model is an environmental protection type activated carbon deep processing mixing device, and when working,

[0028] (1) open the sealing cover 11 at the top of the mixing container 1, add the activated carbon raw materials and additives into the container according to a certain proportion, and then close the sealing cover 11.

[0029] (2) start the first driving motor 22 and the second driving motor 33; after the first driving motor 22 is started, the first driving motor 22 transmits power to the stirring shaft 2 through the shaft coupling.

[0030] After the stirring shaft 2 obtains power, the stirring shaft 2 starts to rotate and drives the stirring blades 21 mounted on the stirring shaft 2 to rotate together; in the rotating process of the stirring blades 21.

[0031] The horizontal stirring blade 211 can exert shearing force and pushing force on the activated carbon in the horizontal plane when the stirring shaft 2 rotates, so that the activated carbon is dispersed and mixed in the horizontal direction; the inclined stirring blade 212 provides a vertical component for the activated carbon in the rotating process due to the inclined structure, and drives the activated carbon to migrate and exchange in the vertical direction. The horizontal stirring blade 211 and the inclined stirring blade 212 are arranged on the stirring shaft 2 in a specific arrangement and distribution rule, and cooperate with each other to build a three-dimensional stirring area around the stirring shaft 2 which can realize the simultaneous mixing of the activated carbon in the horizontal and vertical directions, thereby significantly improving the mixing uniformity and efficiency of the activated carbon, and meeting the mixing requirements under different activated carbon characteristics and mixing processes.

[0032] Meanwhile, the central shaft 32 rotates under the drive of the second driving motor 33, and the spiral blade 31 rotates with the central shaft 32. When the spiral blade 31 rotates, the activated carbon is pushed by the spiral blade 31 and moves upward along the spiral line direction of the spiral blade 31, which can transport the activated carbon close to the container wall upward, and then mix it into the central area by the stirring blade 21, further improving the mixing uniformity of the activated carbon.

[0033] Since there is a gap between the spiral blade 31 and the inner wall of the container, the activated carbon will also be constrained and rubbed by the container wall during upward transportation, so that the activated carbon will also produce certain radial and circumferential movement while moving upward, further promoting the mixing of the activated carbon; by the synergistic effect of the stirring blade 21 and the spiral conveying device 3, the activated carbon can be fully mixed in the horizontal and vertical directions.

[0034] (3) The mixed activated carbon is discharged from the discharge port 12 by manually controlling the electromagnetic valve.
