Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a device for treating printing ink wastewater. Background Technology

[0002] Printing is the process of transferring ink from original manuscripts such as text, pictures, photographs, and anti-counterfeiting materials to a substrate through processes such as plate making, inking, and pressing. In the industrial printing production process, wastewater containing ink is often generated. This wastewater needs to be treated before being discharged to prevent environmental pollution.

[0003] Citing Chinese invention patent publication number "CN116621401A", the invention comprises a base, a reaction cylinder, and a flotation tank. A rotating mechanism is fixedly installed at the bottom of the base, and a stirring mechanism is provided inside the reaction cylinder. This invention utilizes a rotating mounting shaft with a top cavity that rotatably engages with a sleeve at the bottom of an intermediate sleeve. When the push rod drives the pressure plate downwards within the intermediate sleeve, it compresses the hydraulic pressure within the internal cavity system. This causes the first one-way valve on the upper side frame of the mounting shaft to open, but the reagent is not yet fully ejected. Upon elastic reset, the second one-way valve opens, automatically replenishing the reagent. In practice, during reagent injection, it can be injected from inside the waste liquid simultaneously with rotation and agitation.

[0004] Existing treatment devices suffer from insufficient uniformity in reagent mixing, leading to incomplete flocculation and affecting the overall treatment efficiency of the device. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a printing ink wastewater treatment device to solve the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: a printing ink wastewater treatment device, comprising a reaction cylinder, an aeration mechanism fixedly connected to the bottom of the reaction cylinder, a conveying mechanism rotatably connected inside the reaction cylinder, the conveying mechanism comprising a rotating shaft, a shear plate fixedly connected to the surface of the rotating shaft, a baffle mechanism fixedly connected to the surface of the rotating shaft, and a spraying pipe fixedly connected to the top of the reaction cylinder.

[0007] The conveying mechanism includes:

[0008] Fan blades, which are fixedly connected to the surface of the rotating shaft;

[0009] The spiral blade is rotatably connected to the inside of the rotating shaft via the output shaft. The spiral blade is made of 316L stainless steel, which is highly resistant to ink corrosion. The diameter of the spiral blade is 300 mm, the height is 1200 mm, the wall thickness is 5 mm, and the spiral angle is 45 degrees.

[0010] Preferably, a fourth pipe is fixedly connected to the top of the rotating shaft, a third pipe is fixedly connected to the top of the fourth pipe, a second rotating pipe is fixedly connected to the top of the third pipe, a second pipe is rotatably connected to the top of the second rotating pipe, a first rotating connecting pipe is rotatably connected to the top of the second pipe, and a first pipe is rotatably connected to the top of the first rotating connecting pipe.

[0011] Preferably, a second motor is fixedly connected inside the rotating shaft, and a spiral blade is fixedly connected inside the second motor via an output shaft. Leak-proof rubber is fixedly connected to the surface of the spiral blade, and a first motor is rotatably connected to the bottom of the rotating shaft via an output shaft.

[0012] Preferably, a fifth pipe is fixedly connected inside the fan blade, and a water outlet pipe is fixedly connected to the surface of the fifth pipe, with the water outlet pipe being fixedly connected inside the fan blade. There are three water outlet pipes.

[0013] Preferably, the deflector mechanism includes a fixed rod, which is fixedly connected to the surface of the rotating shaft. A baffle is fixedly connected to the surface of the fixed rod, and a deflector plate is rotatably connected to the surface of the fixed rod. There are two deflector plates.

[0014] Preferably, the surface of the fixing rod is rotatably connected to a fixing block via an output shaft, and there are two fixing blocks, with a spring fixedly connected between the two fixing blocks.

[0015] Preferably, the aeration mechanism includes a seventh pipe, which is fixedly connected inside the reaction cylinder. One end of the seventh pipe is fixedly connected to an aeration outlet pipe, and the other end of the seventh pipe is fixedly connected to a sixth pipe. An air pump is fixedly connected to the bottom of the sixth pipe.

[0016] Preferably, there are three shearing plates, which are distributed along the axial direction of the rotation axis on the downstream side of the water outlet pipe, and the fixing rod is distributed along the axial direction of the rotation axis on the downstream side of the shearing plates.

[0017] This invention provides a device for treating printing ink wastewater. It has the following beneficial effects:

[0018] 1. This printing ink wastewater treatment device, by setting up spiral blades, starts a second motor to drive the spiral blades to rotate through the output shaft, thereby accelerating the wastewater input from the top through the rotation of the spiral blades and finally spraying it out from the outlet pipe, so that the wastewater is more evenly distributed in the treatment device, which facilitates the full mixing of wastewater and reagents, thereby improving the overall treatment efficiency of the device.

[0019] 2. This printing ink wastewater treatment device, by setting a shear plate, divides the gas generated by aeration from the aeration outlet pipe into smaller and more numerous bubbles, thereby increasing the contact area between the bubbles and the wastewater. The smaller bubbles are also more easily and evenly distributed in the reaction cylinder, thereby enhancing the mixing effect and improving the overall treatment efficiency of the device.

[0020] 3. This printing ink wastewater treatment device, by setting up fan blades, starts the first motor to drive the fan blades to rotate, which, together with the shearing plate, quickly drives the rotation of the wastewater inside the reaction cylinder, further improving the thorough mixing of wastewater and reagents, thereby improving the overall treatment efficiency of the device.

[0021] 4. This printing ink wastewater treatment device, by setting up baffles, causes the wastewater to flow in a tortuous path within the treatment device. The flow direction and velocity of the wastewater constantly change, generating turbulence and eddies, which facilitates thorough mixing of the wastewater and the reagents. At the same time, it effectively extends the water flow path, allowing the wastewater more time to react with the treatment reagents, thereby improving the treatment efficiency of the device. Furthermore, a fixing block is set up, which uses a spring to spring open the baffles, causing the baffles to rotate back and forth, further ensuring thorough mixing of the wastewater and the reagents, and further improving the treatment efficiency of the device.

[0022] 5. This printing ink wastewater treatment device, by placing the shearing plate on the downstream side of the water outlet pipe, allows clean water to be poured into the interior of the rotating shaft, thereby enabling the water sprayed from the water outlet pipe to clean the impurities adhering to the surface of the shearing plate. This eliminates the need for frequent manual intervention, reducing the labor intensity of workers. At the same time, it can promptly remove impurities from the surface and pores of the shearing plate, preventing clogging, maintaining the permeability of the shearing plate, and ensuring that bubbles can be generated uniformly.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

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

[0034] Example 1: Please refer to Figures 1-6 The present invention provides a technical solution: a printing ink wastewater treatment device, including a reaction cylinder 1, an aeration mechanism 5 fixedly connected to the bottom of the reaction cylinder 1, a conveying mechanism 2 rotatably connected inside the reaction cylinder 1, the conveying mechanism 2 including a rotating shaft 27, a shearing plate 3 fixedly connected to the surface of the rotating shaft 27, a baffle mechanism 4 fixedly connected to the surface of the rotating shaft 27, and a spraying pipe 6 fixedly connected to the top of the reaction cylinder 1.

[0035] Conveying mechanism 2 includes:

[0036] Fan blade 214 is fixedly connected to the surface of rotating shaft 27;

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

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

[0039] A second motor 29 is fixedly connected inside the rotating shaft 27. A spiral blade 210 is fixedly connected inside the second motor 29 via an output shaft. A leak-proof rubber 211 is fixedly connected to the surface of the spiral blade 210. A first motor 28 is rotatably connected to the bottom of the rotating shaft 27 via an output shaft.

[0040] A fifth pipe 212 is fixedly connected inside the fan blade 214, and a water outlet pipe 213 is fixedly connected to the surface of the fifth pipe 212. The water outlet pipe 213 is fixedly connected inside the fan blade 214, and there are three water outlet pipes 213.

[0041] In operation, wastewater is first poured into the first pipe 21, then flows through a connecting pipe and finally into the rotating shaft 27 via the fourth pipe 26. The second motor 29 is then started, and its output shaft drives the spiral blades 210 and the leak-proof rubber 211 to rotate together. The leak-proof rubber 211 facilitates wastewater transport, preventing air leakage during transport that could lead to insufficient power and affect wastewater delivery. This accelerates the wastewater rotation to the bottom of the rotating shaft 27, ensuring more even distribution within the treatment device and facilitating thorough mixing with the reagents. The wastewater then exits through the fifth pipe 212 and finally sprays out from the outlet pipe 213. The wastewater sprayed from the outlet pipe 213 passes through the shear plate 3 and enters the reaction chamber. Inside the cylinder 1, the shearing plate 3 is located downstream of the water outlet pipe 213, facilitating cleaning of the shearing plate without frequent manual intervention, reducing the labor intensity of workers. At the same time, it can promptly remove impurities from the surface and pores of the shearing plate, preventing blockage and maintaining its permeability, ensuring uniform bubble generation. When a certain amount of wastewater is poured into 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. The rotation of the rotating shaft 27 drives the fan blade 214 to rotate together, which, together with the shearing plate 3, quickly drives the rotation of the wastewater inside the reaction cylinder 1. Simultaneously, the reagent is poured in through the spray pipe 6 at the top of the reaction cylinder 1, so that the wastewater and reagent inside the reaction cylinder 1 are fully mixed.

[0042] By setting the spiral blades 210, the second motor 29 is started and drives the spiral blades 210 to rotate through the output shaft. This accelerates the wastewater input from the top through the rotation of the spiral blades 210, and finally sprays it out from the outlet pipe 213. This makes the wastewater more evenly distributed in the treatment device, which facilitates the full mixing of wastewater and reagents, thereby improving the overall treatment efficiency of the device.

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

[0044] By setting up fan blades 214, the first motor 28 is started to drive the fan blades 214 to rotate, which, together with the shear plate 3, quickly drives the rotation of the wastewater inside the reaction cylinder 1, further improving the thorough mixing of wastewater and reagents, thereby improving the overall treatment efficiency of the device.

[0045] By placing 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, thereby allowing the water sprayed from the water outlet pipe 213 to clean the impurities adhering to the surface of the shear plate 3. This eliminates the need for frequent manual intervention, reducing the labor intensity of workers. At the same time, it can promptly remove impurities from the surface and pores of the shear plate, preventing blockage, maintaining the permeability of the shear plate, and ensuring that bubbles can be generated uniformly.

[0048] The surface of the fixed rod 41 is rotatably connected to a fixed block 44 via the 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 inside the reaction cylinder 1. One end of the seventh pipe 53 is fixedly connected to an aeration outlet pipe 54, and the other end of the seventh pipe 53 is fixedly connected to a sixth pipe 52. An air pump 51 is fixedly connected to the bottom of the sixth pipe 52.

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

[0051] In operation, 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 plate 42 to rotate as well, causing the wastewater to flow in a tortuous path within the treatment device. The flow direction and velocity of the wastewater constantly change, generating turbulence and eddies, which facilitates thorough mixing of the wastewater and the reagents. At the same time, it effectively extends the water flow path, allowing the wastewater more time to react with the treatment reagents. Simultaneously, the baffle plate 42 sways, impacting the fixed block 44. The fixed block 44, through the spring 45, bounces the baffle plate 42 away, causing it to rotate back and forth, further ensuring thorough mixing of the wastewater and the reagents, and further improving the treatment efficiency of the device.

[0052] By setting up baffles 42, the wastewater flows in a tortuous path within the treatment device. The direction and velocity of the wastewater constantly change, generating turbulence and eddies, which facilitates thorough mixing of the wastewater and the reagents. At the same time, it effectively extends the water flow path, allowing the wastewater more time to interact with the treatment reagents, thereby improving the treatment efficiency of the device. Furthermore, a fixing block 44 is set up, which, through a spring 45, springs the baffles 42 open, causing the baffles 42 to rotate back and forth, further ensuring thorough mixing of the wastewater and the reagents, and further improving the treatment efficiency of the device.
