Description

Technical Field

[0001] This utility model relates to the field of industrial wastewater treatment technology, specifically to an industrial wastewater treatment device with uniform aeration. Background Technology

[0002] With the acceleration of industrialization, the discharge of industrial wastewater is increasing daily. Industrial wastewater often contains large amounts of heavy metals, organic matter, suspended solids, and nutrients such as nitrogen and phosphorus. If discharged directly without effective treatment, it will cause serious pollution to water bodies, soil, and the atmosphere, endangering ecological balance and human health. For example, wastewater containing heavy metals discharged by some chemical enterprises can lead to the deterioration of water quality in surrounding rivers and lakes, causing mass deaths of aquatic organisms and damaging aquatic ecosystems. High-concentration organic wastewater discharged into water bodies will consume dissolved oxygen, causing black and smelly water, and affecting the living environment of nearby residents. Therefore, efficient and reliable industrial wastewater treatment technologies and equipment have become a key requirement in the field of environmental protection.

[0003] Traditional industrial wastewater treatment equipment has revealed numerous problems in practical applications. In the aeration stage, many traditional devices employ simple aeration methods, such as perforated pipe aeration or surface aeration. Perforated pipe aeration is prone to uneven aeration, with insufficient aeration in some areas. This prevents microorganisms from obtaining enough dissolved oxygen for metabolic activities, thus affecting the decomposition of pollutants in the wastewater. While surface aeration can increase the gas-liquid contact area to some extent, its aeration effect on deep wastewater is poor, failing to meet the aeration requirements of the entire wastewater treatment tank. Traditional equipment also has shortcomings in reagent addition and mixing. Some devices rely on manual addition of reagents, which is not only inefficient but also lacks effective stirring and mixing devices during the mixing process. This results in uneven mixing of reagents and wastewater, hindering the full chemical reaction and reducing the efficiency and quality of wastewater treatment. Utility Model Content

[0004] The purpose of this invention is to provide a uniformly aerated industrial wastewater treatment device, which solves the technical problem of uneven distribution of dissolved oxygen in wastewater due to unreasonable distribution of aeration devices in traditional industrial wastewater treatment equipment, and the inability of the reagent to be quickly and evenly dispersed in the wastewater. It achieves uniform aeration, enhances the decomposition ability of microorganisms on pollutants, significantly improves the wastewater treatment effect, and accelerates the wastewater treatment process.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a uniformly aerated industrial wastewater treatment device, comprising an industrial wastewater treatment tank, a chemical addition rotating mixing section, and a uniform aeration rotating section; a ladder is fixedly installed on the outer wall of the industrial wastewater treatment tank; the chemical addition rotating mixing section is located on the outer wall of the industrial wastewater treatment tank; and the uniform aeration rotating section is located inside the industrial wastewater treatment tank.

[0006] Preferably, the chemical solution addition rotating mixing section specifically includes: a support column, symmetrically fixedly installed on the bottom outer wall of the industrial wastewater treatment tank; a support pad, fixedly installed on the bottom outer wall of the support column; a chemical tank, fixedly installed on one side outer wall of the industrial wastewater treatment tank; a fixed mounting frame, fixedly installed on the bottom outer wall of the industrial wastewater treatment tank; and a sealing sleeve, equidistantly fixedly installed on the bottom inner wall of the industrial wastewater treatment tank.

[0007] Preferably, a dosing hopper is connected to the top of the medicine tank, a dosing pump is connected to one side of the outer wall of the medicine tank, and a dosing pipe is connected to the output end of the dosing pump.

[0008] A reagent tank is installed, which works in conjunction with a dosing pump, a diversion block, and connecting pipes. The dosing pump accurately extracts the reagent from the tank based on the wastewater quality and treatment requirements, delivers it to the diversion block through the dosing pipe, and then evenly injects it into the industrial wastewater treatment tank through the connecting pipe. This dosing method ensures a reasonable ratio of reagent to wastewater, avoids waste or insufficient dosing, allows the chemical reaction to proceed fully during wastewater treatment, effectively removes pollutants from the wastewater, and significantly improves the treatment effect.

[0009] Preferably, the outer wall of the dosing pipe is provided with a diversion block one and a diversion block two at equal intervals. One side of the outer wall of the diversion block one and the diversion block two is provided with a connecting pipe. The other end of the connecting pipe movably penetrates the outer wall of the industrial wastewater treatment tank and extends into the interior of the industrial wastewater treatment tank.

[0010] Preferably, a drive motor is fixedly mounted at equal intervals on the inner wall of the fixed mounting bracket, and a rotating rod is fixedly connected to the output end of the drive motor.

[0011] Preferably, the other end of the rotating rod movably penetrates the bottom outer wall of the industrial wastewater treatment tank and extends into the interior of the industrial wastewater treatment tank. The sealing sleeve is fitted onto the outer wall of the rotating rod, and mixed flow fan blades are fixedly installed at equal intervals around the outer circumference of the rotating rod.

[0012] The system is equipped with a mixed-flow fan blade. The chemical tank, along with the drive motor and the mixed-flow fan blade, allows the injected chemical to be thoroughly mixed with the wastewater after the chemical is added. The special structure and layout of the mixed-flow fan blade enable the chemical to diffuse rapidly in the wastewater, preventing local accumulation of the chemical, promoting full contact between the chemical and pollutants in the wastewater, accelerating the chemical reaction process, improving wastewater treatment efficiency, and reducing treatment time.

[0013] Preferably, the uniform aeration rotating part specifically includes: an air block, equidistantly arranged inside the industrial wastewater treatment tank; a connecting pipe, connected to the top of the air block; a fixed bracket, equidistantly fixedly installed on the top outer wall of the industrial wastewater treatment tank; an aeration blower, fixedly installed on the outer wall of the industrial wastewater treatment tank; and an electrical control cabinet, fixedly installed on the outer wall of the industrial wastewater treatment tank.

[0014] Preferably, the outer wall of the air block is connected to an aeration pipe, the output end of the aeration blower is connected to an air pipe, each of the fixed supports has a rotating slot, the inner wall of the rotating slot is rotatably connected to a rotating shaft tube, one end of the rotating shaft tube is connected to the other end of the air pipe, the other end of the rotating shaft tube is connected to a straight pipe, the other end of the straight pipe is connected to a connecting pipe, and the bottom outer wall of the air block is fixedly connected to the top outer wall of the rotating rod.

[0015] An aeration pipe is installed, which is closely connected to the air block. The air generated by the aeration blower enters the air block through the air pipe, rotating shaft pipe, and connecting pipe, and is then evenly dispersed into the sewage by the aeration pipe. The special structure and layout of the aeration pipe ensures that the air is evenly distributed in the sewage in the form of tiny bubbles, which increases the gas-liquid contact area, improves the oxygen dissolution efficiency, provides sufficient dissolved oxygen for microorganisms, promotes the decomposition of pollutants in the sewage by microorganisms, effectively improves the sewage treatment effect, and ensures that the treated water quality meets the discharge standards.

[0016] This invention provides an industrial wastewater treatment device with uniform aeration. It has the following beneficial effects:

[0017] (1) This utility model uses a drive motor on a fixed mounting frame to drive the rotating rod and the mixing fan blades to rotate at high speed. The mixing fan blades rotate in the sewage, generating a strong stirring force, which makes the added agent and sewage mix quickly and thoroughly. This efficient mixing method accelerates the speed of chemical reaction, allowing the agent to play a role more quickly, decompose pollutants in sewage, greatly improve the efficiency of sewage treatment, shorten the treatment time, and the rapid mixing makes the agent evenly distributed in the sewage, avoiding the situation of excessively high or low concentration of the agent in some areas. The uniform distribution of the agent ensures that the chemical reaction in the entire sewage treatment tank is carried out evenly, and improves the thoroughness of the reaction.

[0018] (2) This utility model uses air blocks that are evenly distributed inside the industrial wastewater treatment tank. The aeration pipes connected to the outer wall can release air into the wastewater from multiple positions, so that the bubbles are evenly distributed in all directions in the wastewater, ensuring that the wastewater in the entire wastewater treatment tank can be fully aerated, promoting the decomposition of pollutants in the wastewater by microorganisms. The air blocks are connected to the rotating rod. As the rotating rod rotates, the air blocks and aeration pipes also rotate. This dynamic aeration method can continuously change the distribution position and path of the bubbles in the wastewater, further enhancing the uniformity of aeration, making the contact between wastewater and oxygen more sufficient and uniform, and improving the aeration effect.

[0025] 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 present invention, and should not be construed as limiting the present invention.

[0026] Example 1:

[0027] Addressing the problem that current aeration devices are poorly distributed, leading to uneven dissolved oxygen distribution in wastewater and preventing the rapid and uniform dispersion of chemicals, this invention provides a preferred embodiment of a uniformly aerated industrial wastewater treatment device, for example... Figures 1-4 As shown: A uniform aeration industrial wastewater treatment device includes an industrial wastewater treatment tank 1, a chemical addition rotating mixing section 3, and a uniform aeration rotating section 4. A ladder 2 is fixedly installed on the outer wall of the industrial wastewater treatment tank 1. The chemical addition rotating mixing section 3 is located on the outer wall of the industrial wastewater treatment tank 1. The uniform aeration rotating section 4 is located inside the industrial wastewater treatment tank 1.

[0028] The chemical solution addition rotating mixing section 3 specifically includes: a support column 311, symmetrically fixedly installed on the bottom outer wall of the industrial wastewater treatment tank 1; a support pad 312, fixedly installed on the bottom outer wall of the support column 311; a chemical tank 313, fixedly installed on one side outer wall of the industrial wastewater treatment tank 1; a fixed mounting bracket 319, fixedly installed on the bottom outer wall of the industrial wastewater treatment tank 1; and a sealing sleeve 3111, equidistantly fixedly installed on the bottom inner wall of the industrial wastewater treatment tank 1.

[0029] The top of the medicine tank 313 is connected to a dosing hopper 318, and a dosing pump 314 is connected to one side of the outer wall of the medicine tank 313. The output end of the dosing pump 314 is connected to a dosing pipe.

[0030] The outer wall of the dosing pipe is provided with a diversion block 1 315 and a diversion block 2 316 at equal intervals. One side of the outer wall of the diversion block 1 315 and the diversion block 2 316 is provided with a connecting pipe 317. The other end of the connecting pipe 317 movably penetrates the outer wall of the industrial wastewater treatment tank 1 and extends into the interior of the industrial wastewater treatment tank 1.

[0031] A drive motor 3112 is fixedly mounted at equal intervals on the inner wall of the fixed mounting bracket 319, and a rotating rod 3113 is fixedly connected to the output end of the drive motor 3112.

[0032] The other end of the rotating rod 3113 movably penetrates the bottom outer wall of the industrial wastewater treatment tank 1 and extends into the interior of the industrial wastewater treatment tank 1. The sealing sleeve 3111 is fitted on the outer wall of the rotating rod 3113, and the circumference of the outer wall of the rotating rod 3113 is fixedly installed with mixing fan blades 3114 at equal intervals.

[0033] In this embodiment, the drive motor 3112 on the fixed mounting bracket 319 is started. The output end of the drive motor 3112 drives the rotating rod 3113 to rotate. The rotating rod 3113 passes through the sealing sleeve 3111 and enters the industrial wastewater treatment tank 1. The mixing fan blades 3114 on its outer wall rotate accordingly to stir the wastewater, so that the added agent is fully mixed with the wastewater, accelerating the chemical reaction. At the same time, the rotating rod 3113 drives the air block 411 connected to the top to rotate, further enhancing the uniformity of aeration and the flow of wastewater. The rapid mixing makes the agent evenly distributed in the wastewater, avoiding the situation of excessively high or low local concentration of the agent. The uniform distribution of the agent ensures that the chemical reaction in the entire wastewater treatment tank is carried out uniformly, improving the thoroughness of the reaction.

[0034] Example 2:

[0035] Please see Figures 1-4 Furthermore, based on Embodiment 1, the uniform aeration rotating part 4 specifically includes: an air block 411, equidistantly arranged inside the industrial wastewater treatment tank 1; a connecting pipe 412, connected to the top of the air block 411; a fixed bracket 414, equidistantly fixedly installed on the top outer wall of the industrial wastewater treatment tank 1; an aeration blower 415, fixedly installed on the outer wall of the industrial wastewater treatment tank 1; and an electrical control cabinet 417, fixedly installed on the outer wall of the industrial wastewater treatment tank 1.

[0036] An aeration pipe 413 is connected to the outer wall of the aeration block 411. An air pipe 416 is connected to the output end of the aeration blower 415. Rotating slots 418 are provided on each of the fixed supports 414. A rotating shaft tube 419 is rotatably connected to the inner wall of the rotating slot 418. One end of the rotating shaft tube 419 is connected to the other end of the air pipe 416. A straight pipe 4111 is connected to the other end of the rotating shaft tube 419. The other end of the straight pipe 4111 is connected to the connecting pipe 412. The bottom outer wall of the aeration block 411 is fixedly connected to the top outer wall of the rotating rod 3113.

[0037] In this embodiment, the aeration blower 415 is started by the electrical control cabinet 417. The compressed air generated by the aeration blower 415 is delivered to the rotating shaft tube 419 through the air pipe 416. The rotating shaft tube 419 introduces the air into the air block 411 through the straight pipe 4111 and the connecting pipe 412. Then, the air is evenly released into the sewage in the form of tiny bubbles by the aeration pipe 413 on the outer wall of the air block 411. The rotating rod 3113 drives the air block 411 connected to the top to rotate, further enhancing the uniformity of aeration and the flow of sewage, and achieving uniform aeration. This dynamic aeration method can continuously change the distribution position and path of the bubbles in the sewage, further enhancing the uniformity of aeration, making the contact between sewage and oxygen more sufficient and uniform, and improving the aeration effect.

[0040] Step 2: According to the wastewater quality and treatment requirements, add an appropriate amount of treatment agent to the agent tank 313 through the dosing hopper 318, start the dosing pump 314, the dosing pump 314 draws out the agent in the agent tank 313 and delivers it to the diversion block 1 315 and diversion block 2 316 through the dosing pipe. The diversion block 1 315 and diversion block 2 316 distribute the agent evenly to the connecting pipe 317, and the connecting pipe 317 then injects the agent into the industrial wastewater treatment tank 1.

[0041] Step 3: Start the aeration blower 415 through the electrical control cabinet 417. The compressed air generated by the aeration blower 415 is delivered to the rotating shaft tube 419 through the air pipe 416. The rotating shaft tube 419 introduces the air into the air block 411 through the straight pipe 4111 and the connecting pipe 412. Then, the air is evenly released into the sewage in the form of tiny bubbles through the aeration pipe 413 on the outer wall of the air block 411, so as to achieve uniform aeration.

[0042] Step 4: Start the drive motor 3112 on the fixed mounting bracket 319. The output end of the drive motor 3112 drives the rotating rod 3113 to rotate. The rotating rod 3113 passes through the sealing sleeve 3111 and enters the industrial wastewater treatment tank 1. The mixing fan blades 3114 on its outer wall rotate accordingly to stir the wastewater, so that the added agents are fully mixed with the wastewater and the chemical reaction is accelerated. At the same time, the rotating rod 3113 drives the air block 411 connected to the top to rotate, further enhancing the uniformity of aeration and the flow of wastewater.

[0043] Step 5: During equipment operation, monitor the operating status of the aeration blower 415 and drive motor 3112 in real time through the electrical control cabinet 417, including parameters such as current, voltage, and speed. Regularly check the remaining amount of chemicals in the chemical tank 313 and replenish the chemicals in time. Regularly clean the aeration pipe 413, connecting pipe 317 and other pipes to prevent blockage and ensure normal operation of the equipment.
