DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0033] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but are not to be construed as limiting the present invention.

[0034] Example 1: Please refer to Figure 1-6 The present invention provides a technical solution: a printing ink wastewater treatment device, comprising a reaction cylinder 1, an aeration mechanism 5 fixedly connected to the bottom of the reaction cylinder 1, a conveying mechanism 2 rotatably connected to the interior of the reaction cylinder 1, the conveying mechanism 2 comprising a rotating shaft 27, a shear plate 3 fixedly connected to the surface of the rotating shaft 27, a baffle mechanism 4 also fixedly connected to the surface of the rotating shaft 27, and a spray pipe 6 fixedly connected to the top of the reaction cylinder 1;

[0035] The conveying mechanism 2 includes:

[0036] The fan blades 214 are fixedly connected to the surface of the rotating shaft 27;

[0037] The spiral blade 210 is rotatably connected to the interior of the rotating shaft 27 via the output shaft.

[0038] The top of the rotating shaft 27 is fixedly connected to the fourth pipe 26, the top of the fourth pipe 26 is fixedly connected to the third pipe 25, the top of the third pipe 25 is fixedly connected to the second rotating pipe 23, the top of the second rotating pipe 23 is rotatably connected to the second pipe 24, the top of the second pipe 24 is rotatably connected to the first rotating connecting pipe 22, and the top of the first rotating connecting pipe 22 is rotatably connected to the first pipe 21.

[0039] The interior of the rotating shaft 27 is fixedly connected to the second motor 29, the interior of the second motor 29 is fixedly connected to the spiral blade 210 via the output shaft, the surface of the spiral blade 210 is fixedly connected to the leakage-proof rubber 211, and the bottom of the rotating shaft 27 is rotatably connected to the first motor 28 via the output shaft.

[0040] The inner part of the fan blade 214 is fixedly connected with the fifth pipe 212 . The surface of the fifth pipe 212 is fixedly connected with the water outlet pipe 213 . The water outlet pipe 213 is fixedly connected to the inner part of the fan blade 214 . There are three water outlet pipes 213 .

[0041] When in use, first pour the wastewater into the first pipe 21, then connect the wastewater to the fourth pipe 26 and finally flow into the interior of the rotating shaft 27 through the pipe connection, then start the second motor 29, and the start of the second motor 29 drives the spiral blade 210 and the leak-proof rubber 211 to rotate together through the output shaft. The leak-proof rubber 211 promotes the transportation of wastewater, avoids air leakage during the transportation of wastewater, and causes insufficient power for wastewater transportation to affect the infusion of wastewater, thereby accelerating the rotation of the wastewater to the bottom of the rotating shaft 27, so that the wastewater is more evenly distributed in the treatment device, which facilitates the full mixing of the wastewater and the reagent, and then finally sprayed out from the outlet of the outlet pipe 213 through the fifth pipe 212. The wastewater sprayed out of the outlet pipe 213 is poured into the reaction through the shear plate 3 Inside the cylinder 1, the shear plate 3 is arranged on the downstream side of the outlet pipe 213, which is convenient for cleaning the shear plate and does not require frequent manual participation, reducing the labor intensity of the staff. At the same time, impurities on the surface and pores of the shear plate can be removed in time to prevent the shear plate from being blocked, maintain the permeability of the shear plate, and ensure that bubbles can be generated evenly. After a certain amount of wastewater is poured into the interior of the reaction cylinder 1, the first motor 28 is started. The start of the first motor 28 drives the rotating shaft 27 to rotate through the output shaft, and the rotation of the rotating shaft 27 drives the fan blades 214 to rotate together, and cooperates with the shear plate 3 to quickly drive the rotation of the wastewater inside the reaction cylinder 1. At the same time, the medicine is poured into the medicine spraying pipe 6 at the top of the reaction cylinder 1, so that the wastewater and the medicine inside the reaction cylinder 1 are fully mixed.

[0042] By setting the spiral blade 210 and starting the second motor 29 to drive the spiral blade 210 to rotate through the output shaft, the wastewater input from the top is accelerated by the rotation of the spiral blade 210 and finally sprayed out from the outlet pipe 213, so that the wastewater is more evenly distributed in the treatment device, which facilitates the full mixing of the wastewater and the reagent, thereby improving the overall treatment efficiency of the device.

[0043] By setting the shear plate 3, the gas generated by aeration in the aeration outlet pipe 54 is divided into smaller and more bubbles, thereby increasing the contact area between the bubbles and the wastewater, and the small bubbles are more easily evenly distributed in the reaction tube 1, thereby enhancing the mixing effect and improving the overall treatment efficiency of the device.

[0044] By providing the fan blades 214 and starting the first motor 28 to drive the fan blades 214 to rotate, the shear plate 3 is used to quickly drive the wastewater inside the reaction tube 1 to rotate, further improving the sufficient mixing of the wastewater and the reagent, thereby improving the overall treatment efficiency of the device.

[0045] By setting the shear plate 3 on the downstream side of the water outlet pipe 213, clean water can be poured into the interior of the rotating shaft 27, so that the water sprayed from the water outlet pipe 213 can clean the impurities sticking to the surface of the shear plate 3. There is no need for frequent manual intervention, which reduces the labor intensity of the staff. At the same time, impurities on the surface and pores of the shear plate can be removed in time to prevent the shear plate from being blocked, maintain the permeability of the shear plate, and ensure that bubbles can be generated evenly.

[0046] Example 2: Please refer to Figure 1-8 Based on the first embodiment, the present invention provides a technical solution:

[0047] The deflector mechanism 4 includes a fixed rod 41, which is fixedly connected to the surface of the rotating shaft 27. A baffle 43 is fixedly connected to the surface of the fixed rod 41. A deflector 42 is rotatably connected to the surface of the fixed rod 41. There are two deflectors 42.

[0048] A fixed block 44 is rotatably connected to the surface of the fixed rod 41 via an output shaft. There are two fixed blocks 44 , and a spring 45 is fixedly connected between the two fixed blocks 44 .

[0049] The aeration mechanism 5 includes a seventh pipe 53, which is fixedly connected to the inside of the reaction tube 1. One end of the seventh pipe 53 is fixedly connected to the aeration outlet pipe 54, the other end of the seventh pipe 53 is fixedly connected to the sixth pipe 52, and the bottom of the sixth pipe 52 is fixedly connected to the air pump 51.

[0050] There are three shear plates 3 , which are distributed on the downstream side of the water outlet pipe 213 along the axial direction of the rotation shaft 27 , and the fixing rods 41 are distributed on the downstream side of the shear plates 3 along the axial direction of the rotation shaft 27 .

[0051] During use, the rotation of the rotating shaft 27 also drives the fixed rod 41 to rotate. The rotation of the fixed rod 41 drives the baffle 42 to rotate together, so that the wastewater flows in a zigzag route in the treatment device. The flow direction and flow rate of the wastewater are constantly changing, which will produce turbulence and eddy currents, which are conducive to the full mixing of the wastewater and the reagent. At the same time, it effectively extends the water flow path, allowing the wastewater to have more sufficient time to react with the treatment reagent. At the same time, the baffle 42 shakes, and the baffle 42 hits the fixed block 44 while shaking. The fixed block 44 rebounds the baffle 42 through the spring 45, thereby causing the baffle 42 to rotate back and forth, further making the wastewater and the reagent fully mixed, and further improving the treatment efficiency of the device.

[0052] By setting the baffle 42, the baffle 42 makes the wastewater flow in a zigzag route in the treatment device, and the flow direction and flow rate of the wastewater are constantly changing, which will produce turbulence and eddy currents, which are conducive to the full mixing of the wastewater and the reagent. At the same time, it effectively extends the water flow path, allowing the wastewater to have more sufficient time to react with the treatment reagent, thereby improving the treatment efficiency of the device. A fixed block 44 is set, and the fixed block 44 bounces the baffle 42 open through the spring 45, so that the baffle 42 rotates back and forth, further making the wastewater and the reagent fully mixed, and further improving the treatment efficiency of the device.
