Detailed implementation mode

[0019] The following will further elaborate on this application in conjunction with the attached Figure 1 - attached Figure 4 , and make a more detailed description of this application.

[0020] Referring to Figure 1 , Figure 2 , an automatic feeding activated carbon stirring tank includes a stirring tank body 1, a stirring motor 2 is installed on the stirring tank body 1, a stirring shaft 3 is installed at the output end of the stirring motor 2, a stirring blade 4 is installed on the stirring shaft 3, a vacuum pump 5 is installed on the stirring tank body 1, a suction pipe 6 is installed on the stirring tank body 1, one end of the suction pipe 6 away from the stirring tank body 1 is connected to an activated carbon crushing assembly 7, a discharge pipe 8 is installed at the lower end of the stirring tank body 1, and the discharge pipe 8 is connected to an activated carbon filter element forming device; a plurality of first liquid level sensors 9 are installed inside the stirring tank body 1, a solenoid valve 10 is installed on the discharge pipe 8, and the first liquid level sensors 9 are electrically connected to the solenoid valve 10 and the vacuum pump 5; a second liquid level sensor 13 is installed in the activated carbon filter element forming device, and the second liquid level sensor 13 is electrically connected to the solenoid valve 10; during the production of the activated carbon filter element, water is loaded into the crushing assembly, then carbon powder is mixed with water, and the activated carbon is crushed by the crushing assembly. The first liquid level sensors are installed at the upper end position, the middle position and the lower side position inside the stirring tank body 1. When the liquid level in the stirring tank body 1 drops to the middle position, the control center 12 controls the vacuum pump 5 to start working, and at the same time closes the solenoid valve 10, a negative pressure is generated inside the stirring tank body 1, and the liquid mixture of the activated carbon powder and water mixed in the crushing assembly 7 is sucked into the inside of the stirring tank body 1. When the liquid in the activated carbon filter element forming device is insufficient, the second liquid level sensor 13 in the activated carbon filter element forming device controls the solenoid valve 10 to open, and the mixed activated carbon liquid is supplemented into the activated carbon filter element forming device; thus, automatic feeding can be realized, and at the same time, the generation of powder during the addition of activated carbon is reduced (the structure of the activated carbon filter element forming device can refer to CN215085522U, an adsorption rolling mechanism for a carbon rod forming machine, and CN215095878U, an elastic adjustment mechanism for ensuring the rolling fit accuracy).

[0021] The output end of the stirring motor 2 is equipped with a stirring shaft 3, and the stirring shaft 3 is equipped with stirring blades 4. The activated carbon mixed liquid inside the stirring tank body 1 is continuously stirred by the stirring blades 4 driven by the stirring motor 2, so that the activated carbon powder and water are evenly mixed, making the mixture added to the activated carbon filter element forming equipment contain sufficient activated carbon powder. At the same time, it effectively prevents the activated carbon powder from precipitating in the stirring tank body 1 and affecting the flow of the activated carbon powder mixture.

[0022] Refer to Figure 2 , a plurality of flow-stop plates 11 are installed on the inner wall of the stirring tank body 1. The flow-stop plates 11 block the activated carbon powder mixture stirred by the stirring blades 4 to reduce the generation of vortices, which can effectively prevent the unidirectional rotation of the water flow from generating dust between the activated carbon powder and water. At the same time, it makes the flow direction of the activated carbon powder mixture, making the mixing of the carbon powder more uniform.

[0023] Refer to Figure 2 , a transverse support arm 31 is installed on the stirring shaft 3, the stirring blade 4 is fixed on the transverse support arm 31, and the outer edge of the stirring blade 4 is close to the flow-stop plate 11.

[0024] Refer to Figure 2 , the stirring blade 4 is spiral-shaped. The stirring blade 4 is used to turn the activated carbon mixed liquid up and down. Under the rotation of the stirring blade 4, an upward thrust is generated on the activated carbon powder mixture. At the same time, the activated carbon powder mixture flows downward under the action of gravity, so that the activated carbon powder mixture turns up and down, making the activated carbon powder mixture fully and evenly mixed.

[0025] Refer to Figure 3 , a control center 12 is installed on the stirring tank body 1. The control center 12 is electrically connected to the first liquid level sensor 9, the solenoid valve 10, the vacuum pump 5 and the second liquid level sensor 13. When the activated carbon powder mixture is lower than the first liquid level sensor 9 in the middle of the stirring tank body 1, the control center 12 controls the solenoid valve 10 to close and the vacuum pump 5 to open. A negative pressure is generated in the stirring tank body 1, and the activated carbon powder mixture enters the stirring tank body 1 from the suction pipe 6. When the liquid level touches the first liquid level sensor 9 on the upper side of the stirring tank body 1, the vacuum pump 5 stops working. There are two second liquid level sensors 13 installed in the activated carbon filter element forming equipment. When the liquid level in the activated carbon filter element forming equipment drops and is lower than the lower second liquid level sensor 13, the solenoid valve 10 opens, and the activated carbon powder mixture is supplemented into the activated carbon filter element forming equipment under the action of the liquid level difference. When the liquid level in the activated carbon filter element forming equipment touches the upper second liquid level sensor 13, the solenoid valve 10 closes to stop supplementing the activated carbon powder mixture.

[0026] Refer to Figure 4, the activated carbon crushing assembly 7 includes a crushing chamber 71, a rotating crushing knife 72 installed on the crushing chamber 71, a fixed crushing knife 73 installed in the crushing chamber 71, and a crushing motor 74 for driving the rotation of the rotating crushing knife 72; a flywheel 75 is fixed to one end of the rotating crushing knife 72 away from the crushing motor 74; when processing activated carbon powder, first add an appropriate amount of water to the crushing chamber 71, then add activated carbon blocks to the crushing chamber 71, the crushing motor 74 drives the rotating crushing knife 72, the rotating crushing knife 72 and the fixed crushing knife 73 form a shearing force, fully crushing the activated carbon blocks and uniformly mixing them with water; a flywheel 75 is fixed to one end of the rotating crushing knife 72 away from the crushing motor 74, and under the action of the inertia generated by the flywheel 75, the rotating crushing knife 72 has sufficient impact force and better crushing effect.

[0027] Optionally, the suction pipe 6 is connected to the crushing chamber 71, and after the vacuum pump 5 creates a negative pressure in the stirring tank body 1, the carbon powder mixture is sucked into the stirring tank body 1.
