Description

Technical Field

[0001] This utility model relates to the technical field of wastewater treatment, and in particular to a wastewater iron-carbon micro-electrolysis reaction tank. Background Technology

[0002] The wastewater iron-carbon micro-electrolysis reactor refers to the micro-electrolysis of wastewater through a galvanic cell formed by immersing iron and carbon in water. This process causes the iron to form ferrous hydroxide, which has a coagulation effect, thereby promoting the sedimentation of suspended particles in the wastewater. In the prior art, a utility model patent with patent application number 202320812785.7 discloses a micro-nano aerated iron-carbon micro-electrolysis wastewater treatment device, which mainly includes an inlet regulating tank, an iron-carbon micro-electrolysis reaction tank, a micro-nano bubble generating mechanism, and a magnetic separation sludge removal mechanism. In use, iron-carbon micro-electrolysis packing is added to the reaction tank, and then acidic wastewater is added to the reaction tank to contact the iron-carbon micro-electrolysis packing for a period of time, allowing iron ions to enter the wastewater. Afterwards, the wastewater is adjusted to alkaline, causing iron ions to combine with hydroxide ions to form ferric hydroxide, which has a coagulation effect. This causes suspended solids in the wastewater to combine with the ferric hydroxide and settle at the bottom to form sludge. However, the inventor believes that this device has the following problems during use: during the wastewater settling stage, because the iron-carbon packing is still located in the reaction tank, the suspended solids settling in the wastewater also settle on the iron-carbon packing, affecting the reuse of the iron-carbon packing and making it inconvenient to use. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a wastewater iron-carbon micro-electrolysis packing material that can be automatically removed from the wastewater before the suspended solids settle, preventing sludge from adhering to the packing material during the settling process. This facilitates the reuse of the iron-carbon micro-electrolysis packing material and makes the wastewater iron-carbon micro-electrolysis reaction tank convenient to use and highly practical.

[0004] This utility model discloses a wastewater iron-carbon micro-electrolysis reactor, comprising a base plate, a support frame, a housing, and an IC reactor. The housing is fixedly mounted on the upper part of the base plate via the support frame, and the housing contains a chamber. The IC reactor is mounted on the upper part of the base plate. It also includes a cylinder, a conveying mechanism, a stirring mechanism, and a moving mechanism. The cylinder contains a cavity, with an opening at the top. Multiple through holes communicating with the cavity are provided on the cylinder. The cylinder is mounted on the moving mechanism for moving the cylinder. The stirring mechanism is mounted on the base plate and the housing, and provides stirring functionality. The conveying mechanism is mounted on the base plate, with its input and output ends connected to the housing and the IC reactor, respectively. The conveying mechanism also provides sludge conveying functionality. In wastewater treatment, wastewater is first added to the chamber of the housing. Then, acid is added to the chamber to adjust the wastewater to acidity, ideally with a pH of 3. Next, iron-carbon micro-electrolysis filler is added to the cavity of the cylinder. The moving mechanism then guides the cylinder into the wastewater, immersing the iron-carbon micro-electrolysis filler in the acid. In the process of preparing wastewater, an electrochemical reaction occurs in the iron-carbon micro-electrolysis packing material, generating iron ions that enter the wastewater. A moving mechanism then elevates the cylinder above the tank, bringing the iron-carbon micro-electrolysis packing material above the wastewater. Alkaline solution is then added to the tank chamber to adjust the wastewater's pH to 9, allowing the iron ions to combine with hydroxide ions in this alkaline environment to form ferric hydroxide, which has flocculating properties. This ferric hydroxide then combines with suspended solids in the wastewater and settles. The sediment settles to the bottom of the chamber, forming sludge. Then, an external water pump and pipes remove the sediment from the upper part of the chamber for further treatment. The sludge from the lower part of the chamber is then transported to the IC reactor via a water conveying mechanism for anaerobic reaction. During wastewater treatment, the iron-carbon micro-electrolysis packing material can be automatically removed from the wastewater before the suspended solids settle, preventing sludge from adhering to it during sedimentation. This facilitates the reuse of the iron-carbon micro-electrolysis packing material, making it convenient and highly practical.

[0005] Preferably, the moving mechanism includes a rotating mechanism, a lifting plate, a hydraulic cylinder, a push rod, a sliding rod, and a lifting plate. The hydraulic cylinder is fixedly mounted on the upper end of the lifting plate. The push rod and the sliding rod are both slidably mounted on the lifting plate. The upper end of the push rod is connected to the output end of the hydraulic cylinder. The lifting plate is fixedly mounted on the lower ends of the push rod and the sliding rod. The cylinder is mounted on the lifting plate through the rotating mechanism, which has a rotating function. The lifting plate is fixedly mounted on a support in the workshop. When the iron-carbon micro-electrolysis filler is removed from the chamber of the box, the hydraulic cylinder is opened. The hydraulic cylinder raises the lifting plate through the push rod. The lifting plate drives the cylinder to rise, and the cylinder drives the iron-carbon micro-electrolysis filler to rise until the cylinder and the iron-carbon micro-electrolysis filler are raised to the top of the box. This facilitates the removal of the iron-carbon micro-electrolysis filler from the chamber of the box and improves convenience.

[0006] Preferably, the rotating mechanism includes a rotating shaft, bevel gear A, bevel gear B, a drive shaft, a fixed plate, and a drive motor. The connecting frame is fixedly installed on the upper part of the cylinder. The lower end of the rotating shaft is fixedly connected to the connecting frame. The rotating shaft is rotatably installed on the lower end of the lifting plate. Bevel gear A is fixedly installed on the rotating shaft. Bevel gear B meshes with bevel gear A. Bevel gear B is fixedly installed on the drive shaft. The drive shaft is rotatably installed on the fixed plate. The input end of the drive shaft is connected to the drive motor. Both the drive motor and the fixed plate are fixedly installed on the lower end of the lifting plate. When the iron-carbon micro-electrolysis filler is immersed in the wastewater in the chamber of the tank for micro-electrolysis reaction, the drive motor is turned on. The drive motor drives bevel gear B to rotate bevel gear A through the drive shaft. Bevel gear A drives the connecting frame to rotate the cylinder through the rotating shaft. The cylinder drives the iron-carbon micro-electrolysis filler to rotate, thereby promoting the relative movement between the iron-carbon micro-electrolysis filler and the wastewater in the chamber of the cylinder. This allows the iron ions generated by the iron-carbon micro-electrolysis filler through electrolysis to be evenly dispersed in the wastewater, facilitating the subsequent sedimentation treatment of the wastewater.

[0007] Preferably, the stirring mechanism includes a servo motor, a rotating shaft, and a fixed frame. The servo motor is fixedly mounted on the base plate, and the rotating shaft is rotatably mounted on the housing and the fixed frame. Multiple sets of stirring blades are arranged on the upper part of the rotating shaft, and all sets of stirring blades are located in the lower part of the housing chamber. The fixed frame is fixedly mounted on the base plate, and the lower end of the rotating shaft is connected to the output end of the servo motor. When adjusting the acidity or alkalinity of the wastewater in the housing chamber, the servo motor is turned on. The servo motor drives the multiple sets of stirring blades to rotate through the rotating shaft, thereby promoting the mixing of wastewater with acid or alkaline solutions in the housing chamber, which facilitates the adjustment of the wastewater pH value.

[0008] Preferably, the conveying mechanism includes a sludge pump, an input pipe, and a sludge conveying pipe. The sludge pump is fixedly installed on the base plate. The input end of the sludge pump is connected to the lower part of the tank chamber through the input pipe, and the output end of the sludge pump is connected to the IC reactor through the sludge conveying pipe. After the wastewater sedimentation treatment is completed, the wastewater that has settled in the upper part of the tank chamber is transported to the outside through an external water pump and conveying pipe. Then, the sludge pump is turned on, so that the sludge settled in the lower part of the tank chamber is transported to the IC reactor for anaerobic treatment in sequence through the input pipe, the sludge pump, and the sludge conveying pipe. This facilitates the transport of sludge.

[0009] Preferably, it also includes an acid-base meter, which is installed on the housing; the above configuration facilitates the monitoring of the acidity and alkalinity of the wastewater in the housing chamber and improves convenience.

[0010] Preferably, the inner wall of the enclosure is provided with a corrosion-resistant coating; this feature improves the corrosion resistance of the enclosure and extends its service life.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: the iron-carbon micro-electrolysis packing can be automatically removed from the wastewater before the suspended solids settle, preventing sludge from adhering to the iron-carbon micro-electrolysis packing during the settling process, which facilitates the reuse of the iron-carbon micro-electrolysis packing, making it convenient to use and highly practical.

[0019] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0020] It should be noted in advance that adjusting the wastewater to acidic is to promote the reaction of iron in the iron-carbon electrolysis packing and to promote the entry of iron ions into the wastewater; adjusting the wastewater to alkaline is to promote the combination of iron ions with hydroxide ions in alkaline water to form ferric hydroxide with flocculation ability, thereby promoting the sedimentation of suspended solids in the wastewater. Example 1

[0021] like Figures 1 to 6The wastewater iron-carbon micro-electrolysis reactor of this utility model includes a base plate 1, a support frame 2, a box body 3, an IC reactor 4, a cylinder 5, a conveying mechanism, a stirring mechanism, and a moving mechanism. The box body 3 is fixedly installed on the upper end of the base plate 1 by the support frame 2. The box body 3 has a cavity inside. The IC reactor 4 is installed on the upper end of the base plate 1. The cylinder 5 has a cavity inside, and the upper end of the cylinder 5 is open. The cylinder 5 has multiple sets of through holes communicating with the cavity. The cylinder 5 is installed on the moving mechanism, which is used to move the cylinder 5. The stirring mechanism is installed on the base plate 1 and... On the tank 3, the stirring mechanism has a stirring function, and the conveying mechanism is installed on the base plate 1. The input and output ends of the conveying mechanism are connected to the tank 3 and the IC reactor 4, respectively. The conveying mechanism has the function of conveying sludge. When treating wastewater, the wastewater is first added to the chamber of the tank 3, and then acid is added to the chamber of the tank 3 to adjust the wastewater to acidity, with the pH value adjusted to 3. Then, the iron-carbon micro-electrolysis packing is added to the cavity of the cylinder 5. Then, the cylinder 5 is moved into the wastewater by the moving mechanism, so that the iron-carbon micro-electrolysis packing in the cylinder 5 can be activated. The filler is immersed in acidic wastewater, causing an electrochemical reaction that generates iron ions that enter the wastewater. A moving mechanism then raises cylinder 5 above tank 3, bringing the iron-carbon micro-electrolysis filler above the wastewater. Alkaline solution is then added to the chamber of tank 3 to adjust the wastewater's pH to 9, allowing the iron ions to combine with hydroxide ions in this alkaline environment to form ferric hydroxide, which has flocculating properties. This ferric hydroxide then reacts with suspended solids in the wastewater. After settling, the sediment settles to the bottom of chamber 3 of the tank, forming sludge. Then, the clear liquid from the upper part of chamber 3 is pumped away by an external water pump and water pipe for further treatment. The sludge from the lower part of chamber 3 is then transported to IC reactor 4 for anaerobic reaction via a water conveying mechanism. During wastewater treatment, the iron-carbon micro-electrolysis packing material can be automatically removed from the wastewater before the suspended solids settle, preventing the sludge from adhering to the packing material during settling. This facilitates the reuse of the iron-carbon micro-electrolysis packing material, making it convenient to use and highly practical.

The cylinder 5 is installed on the lifting plate 10 through the rotating mechanism, which has a rotating function. The lifting plate 6 is fixedly installed on the support in the workshop. When the iron-carbon micro-electrolysis filler is taken out from the chamber of the box 3, the hydraulic cylinder 7 is opened. The hydraulic cylinder 7 raises the lifting plate 10 through the push rod 8. The lifting plate 10 drives the cylinder 5 to rise, and the cylinder 5 drives the iron-carbon micro-electrolysis filler to rise until the cylinder 5 drives the iron-carbon micro-electrolysis filler to rise above the box 3. This facilitates the removal of the iron-carbon micro-electrolysis filler from the chamber of the box 3 and improves convenience.

[0023] like Figure 1 and Figure 4 The rotating mechanism includes a rotating shaft 12, bevel gear A13, bevel gear B14, a drive shaft 15, a fixed plate 16, and a drive motor 17.

The drive motor 17 and the fixed plate 16... All are fixedly installed at the lower end of the lifting plate 10; when the iron-carbon micro-electrolysis packing is immersed in the wastewater in the chamber of the tank 3 for micro-electrolysis reaction, the drive motor 17 is turned on. The drive motor 17 drives the bevel gear B14 to rotate the bevel gear A13 through the drive shaft 15. The bevel gear A13 drives the connecting frame 11 to rotate the cylinder 5 through the rotating shaft 12. The cylinder 5 drives the iron-carbon micro-electrolysis packing to rotate, thereby promoting the relative movement between the iron-carbon micro-electrolysis packing and the wastewater in the chamber of the cylinder 5, so that the iron ions generated by the iron-carbon micro-electrolysis packing through electrolysis are evenly dispersed in the wastewater, which facilitates the subsequent sedimentation treatment of the wastewater.

[0024] like Figure 5 and Figure 6The stirring mechanism includes a servo motor 18, a rotating shaft 19, and a fixed frame 20. The servo motor 18 is fixedly mounted on the base plate 1, and the rotating shaft 19 is rotatably mounted on the housing 3 and the fixed frame 20.

The fixed frame 20 is fixedly mounted on the base plate 1, and the lower end of the rotating shaft 19 is connected to the output end of the servo motor 18. When adjusting the acidity or alkalinity of the wastewater in the chamber of the housing 3, the servo motor 18 is turned on.

The input end of the sludge pump 21 is connected to the lower part of the chamber 3 of the tank through the input pipe 22, and the output end of the sludge pump 21 is connected to the IC reactor 4 through the sludge conveying pipe 23. After the wastewater sedimentation treatment is completed, the wastewater that has settled in the upper part of the chamber 3 of the tank is transported to the outside through an external water pump and conveying pipe. Then, the sludge pump 21 is turned on, so that the sludge settled in the lower part of the chamber 3 of the tank can be transported to the IC reactor 4 for anaerobic treatment in sequence through the input pipe 22, the sludge pump 21, and the sludge conveying pipe 23. This facilitates the transport of sludge.
