Detailed Implementation

[0017] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0018] Please see Figures 1-4 A chemical wastewater treatment device includes a reaction vessel 1, a drive mechanism 3 fixedly connected to the top surface of the reaction vessel 1, an injection port 105 and a liquid inlet 104 opened on the top surface of the reaction vessel 1, a liquid outlet 102 opened on the lower side of the reaction vessel 1, a sludge outlet 103 opened at the bottom of the reaction vessel 1, and a stirring mechanism 2 rotatably connected inside the reaction vessel 1.

[0019] The stirring mechanism 2 includes a first rotating shaft 201. The top of the first rotating shaft 201 extends out of the outer shell 101 of the container and is rotatably connected to the reaction container 1 through a sealing support ring 106. The sealing support ring 106 is fixed to the upper surface of the outer shell 101. A stirring blade 202 is symmetrically fixed to the middle of the first rotating shaft 201. A flow stabilizer 203 is fixedly connected to the lower part of the first rotating shaft 201. A second rotating shaft 204 is rotatably connected inside the first rotating shaft 201. The rotation of the first rotating shaft 201 drives the stirring blade 202 to rotate, thereby accelerating the flocculation reaction process. The flocculated flocs can reduce the disturbance caused by stirring under the action of the flow stabilizer 203.

[0020] The second rotating shaft 204 extends through the upper surface of the first rotating shaft 201 and is rotatably connected to the drive mechanism 3 via the second belt 304. A scraper 205 is fixedly connected to the bottom of the second rotating shaft 204. The scraper 205 is in contact with the inner surface of the container shell 101. The rotation of the second rotating shaft 204 drives the scraper 205 to rotate, which can not only clean the inner wall of the reaction container 1, but also accelerate the discharge of flocculants.

[0021] The stirring blade 202 is composed of multiple stepped blades arranged in a spiral structure with gaps between them and an angle greater than 90 degrees between adjacent stepped surfaces 2021. During the flocculation process, small flocs are mixed with other small flocs to form large flocs by impacting and rolling with the multi-level stepped surfaces, thereby accelerating the aggregation of suspended particles. The spiral arrangement can also generate a downward thrust, which accelerates the flocs into the lower mud storage silo 206 of the reaction vessel 1 and discharges them through the mud outlet 103.

[0022] The drive mechanism 3 includes a first motor 301 and a second motor 302. The output end of the first motor 301 is rotatably connected to the top of the first rotating shaft 201 via a first belt 303. The first motor 301 is fixed to the top surface of the container shell 101 via a bracket 305. The output end of the second motor 302 is rotatably connected to the top of the second rotating shaft 204 via a second belt 304. The second motor 302 is fixed to the top surface of the container shell 101 via a bracket 305.

[0023] Working principle: First, chemical wastewater is added through inlet 104. Then, the first motor 301 is started. The first motor 301 drives the first rotating shaft 201 to rotate via the first belt 303, which in turn drives the stirring blades 202 and the flow stabilizer 203 to rotate. Subsequently, flocculant is added through inlet 105. Under the action of stirring, the flocculant causes the suspended particles in the chemical wastewater to aggregate and grow into small flocs. The small flocs continuously collide and roll with the stepped structure on the stirring blades 202, and interact with other small flocs on the stepped structure. The mixture on the stepped surface 2021 increases and flows out through the gaps between the stepped blades, repeating the above process with the lower stepped blades, eventually forming large flocs that fall into the lower sludge storage bin 206. Flocculation is complete, and the second motor 302 is started. The second motor 302 drives the second rotating shaft 204 to rotate via the second belt 304, which in turn drives the scraper 205 to rotate, accelerating the discharge of the flocs in the sludge storage bin 206 from the sludge outlet 103 and cleaning the inner wall of the sludge storage bin 206.
