Description

Technical Field

[0001] This utility model relates to the field of organic wastewater treatment technology, and in particular to an organic wastewater treatment device with a chemical mixing function. Background Technology

[0002] Organic wastewater treatment equipment is a specialized technology used to remove or transform organic pollutants in wastewater. It decomposes organic matter into harmless substances (such as CO2 and H2O) or recycles them through physical, chemical, or biological methods, achieving wastewater discharge standards or resource recovery. Organic wastewater treatment utilizes physical, chemical, and biological methods to purify wastewater, reduce pollution, and ultimately achieve wastewater recycling and reuse, fully utilizing water resources. In the wastewater treatment process, coagulants are generally added to adsorb impurities in the wastewater, which are then removed through filters.

[0003] In existing organic wastewater treatment devices, when wastewater and chemical solutions are mixed inside the reaction chamber, there is a lack of corresponding anti-clogging mechanisms. This makes it easy for impurities or flocs to clog the sludge outlet or filter screen, thus affecting the discharge of sewage or the entry of water into the micro-electrolysis cell for further purification.

[0004] An existing patent (publication number: CN221166387U) discloses an organic wastewater treatment device with a drug-liquid mixing function. It includes a mounting base with a treatment mechanism positioned above it. The treatment mechanism includes a treatment tank, which is fixedly installed at the top center of the mounting base. A drug-liquid tank is located at the top center of the treatment tank, and two partitions are fixed inside the treatment tank. A drive motor rotates a drive rod, causing multiple sets of stirring rods to rotate in corresponding positions. The drug-liquid tank facilitates improved drug uniformity, while the reaction chamber and micro-electrolysis chamber ensure thorough mixing of wastewater and drug-liquid. Through the partitions and filter screen, the overall wastewater flow remains vertical and is filtered.

[0005] To address the aforementioned issues, existing patents have proposed solutions that use a drive motor to rotate a drive rod, allowing multiple sets of stirring rods to rotate in corresponding positions. The solution tank facilitates improved solution uniformity, and the reaction chamber and micro-electrolysis chamber facilitate thorough mixing of wastewater and solution. However, the mixing effect achieved by relying on the stirring rods during solution mixing is poor, preventing the solution from completely mixing with the wastewater and reducing the wastewater treatment efficiency. Summary of the Invention

[0006] The purpose of this invention is to provide an organic wastewater treatment device with a drug-liquid mixing function. When the transmission pipe rotates, it drives the stirring rod to rotate, thereby stirring and mixing the wastewater and the drug solution. The air pump filters external air through the filter cylinder and draws it in, then sprays it upward through the air outlet on the exhaust device, causing bubbles to be generated at the bottom of the wastewater. The rising, diffusion, and shearing effects of the bubbles provide the necessary conditions for microbial metabolism, pollutant degradation, and homogenization in the wastewater. Furthermore, the rising bubbles create an upward flow velocity, typically 0.3-0.8 m / s, which can drive the wastewater circulation. With the cooperation of the stirring rod, the mixing effect of the drug solution can be improved, thereby solving the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an organic wastewater treatment device with a drug solution mixing function, comprising a device shell, a wastewater pipe connected to the upper surface of the device shell, a mixing mechanism for mixing the drug solution at the upper end of the device shell, and a filtration mechanism for filtering the wastewater outside the mixing mechanism.

[0008] The mixing mechanism includes a drive motor, which is fixed to the upper end of the device housing by bolts. The power output shaft of the drive motor passes through the device housing and is fixed with a transmission pipe. The lower surface of the transmission pipe is connected to two exhaust components. The upper ends of the two exhaust components are provided with several air outlets at equal intervals. A connector is installed on the outer surface of the transmission pipe.

[0009] Preferably, one side of the connector is connected to a delivery pipe, and the end of the delivery pipe is connected to an air pump fixed to the device housing.

[0010] Preferably, the input end of the air pump is connected to a filter cartridge, and two fixed bearings sleeved on the transmission tube are fixed inside the connector.

[0011] Preferably, the outer wall of the transmission tube has a through hole that communicates with the connector, and a plurality of stirring rods are symmetrically welded to the outer surface of the transmission tube.

[0012] Preferably, a filter screen is installed horizontally inside the housing of the device, and a drain valve is connected to the outer wall of the housing of the device.

[0013] Preferably, the filtration mechanism includes two mounting components, both of which are symmetrically fixed to the outer wall of the transmission tube and above the filter screen. The lower ends of both mounting components are telescopically connected to movable blocks.

[0014] Preferably, a collecting component is fixed to the lower surface of the movable block, a scraper is integrally fixed to the lower end of the side wall of the collecting component, and a compression spring fixedly connected to the mounting component is abutted against the upper surface of the movable block.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. Through the set mixing mechanism, the rotation of the transmission pipe will drive the stirring rod to rotate, thereby stirring and mixing the wastewater and the medicine solution. The air pump filters the external air through the filter cartridge and then sprays it upward through the air outlet on the exhaust device, causing bubbles to be generated at the bottom of the wastewater. The rising, diffusion and shearing action of the bubbles provide the necessary conditions for the microbial metabolism, pollutant degradation and mixing and homogenization in the wastewater. In addition, the rising flow velocity formed during the bubble rising process is usually 0.3-0.8m / s, which can drive the wastewater to circulate. With the cooperation of the stirring rod, the mixing effect of the medicine solution can be improved.

[0017] 2. Through the set filtration mechanism, the mounting parts synchronously drive the collection parts to move. With the cooperation of the scraper, the particulate impurities blocked on the upper surface of the filter screen can be scraped into the collection parts, thereby collecting these impurities and reducing the clogging of the filter screen. Furthermore, under the action of the elasticity of the compression spring, the movable block will be pushed to move vertically, so that the scraper can better contact the upper surface of the filter screen and improve the cleaning effect of impurities.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a technical solution:

[0027] Please see Figures 1 to 4 An organic wastewater treatment device with a drug solution mixing function includes a device shell 1, a wastewater pipe 2 connected to the upper surface of the device shell 1, a mixing mechanism for mixing the drug solution at the upper end of the device shell 1, and a filtration mechanism for filtering the wastewater outside the mixing mechanism.

[0028] The mixing mechanism includes a drive motor 3, which is fixed to the upper end of the device housing 1 by bolts. The power output shaft of the drive motor 3 passes through the device housing 1 and is fixed with a transmission pipe 31. The lower surface of the transmission pipe 31 is connected to two exhaust components 32. The upper ends of the two exhaust components 32 are provided with several air outlets 33 at equal intervals. A connector 34 is installed on the outer surface of the transmission pipe 31. A conveying pipe 35 is connected to one side of the connector 34. The end of the conveying pipe 35 is connected to an air pump 36 fixed on the device housing 1. The input end of the air pump 36 is connected to a filter cartridge 37. Two fixed bearings 38 are fixed inside the connector 34 and sleeved on the transmission pipe 31. The outer wall of the transmission pipe 31 is provided with through holes 39 that communicate with the connector 34. Several stirring rods 4 are symmetrically welded to the outer surface of the transmission pipe 31.

[0029] By adopting the above technical solution, before using the organic wastewater treatment device with chemical mixing function, the outer shell 1 of the device is first placed in a suitable position. During use, the pipe of the external conveying equipment is connected to the wastewater pipe 2, allowing wastewater to be discharged into the outer shell 1. A suitable chemical solution can be added into the outer shell 1 through the chemical solution port. The PLC controller controls the drive motor 3 to start, and the filtered wastewater enters the bottom of the outer shell 1, as does the added chemical solution. A fixed bearing 38 is installed on the connecting member 34, preventing the connecting member 34 from rotating when the transmission pipe 31 rotates. The rotation of the transmission pipe 31 drives the stirring rod 4 to rotate, thereby mixing the wastewater and chemical solution. Simultaneously, P... The LC controller controls the start of the air pump 36. The air pump 36 filters the external air through the filter cartridge 37 and then draws it in. The air is then transported to the connector 34 through the delivery pipe 35 and enters through the through hole 39 on the transmission pipe 31. It then enters the two exhaust components 32 and is sprayed upward through the air outlet 33 on the exhaust components 32, thereby generating bubbles at the bottom of the wastewater. The rising, diffusion and shearing action of the bubbles provide the necessary conditions for the microbial metabolism, pollutant degradation and homogenization of the wastewater. The rising flow velocity formed by the bubbles is usually 0.3-0.8 m / s, which can drive the wastewater to circulate. With the cooperation of the stirring rod 4, the mixing effect of the solution can be improved. The treated wastewater can be discharged by opening the drain valve 7.

[0030] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, a filter screen plate 5 is installed horizontally inside the device housing 1. A drain valve 7 is connected to the outer wall of the device housing 1. The filtration mechanism includes mounting parts 6. There are two mounting parts 6. The two mounting parts 6 are symmetrically fixed to the outer wall of the transmission tube 31 and close to the upper part of the filter screen plate 5. The lower ends of the two mounting parts 6 are telescopically connected to movable blocks 61. A collecting part 62 is fixed to the lower surface of the movable block 61. A scraper 63 is integrally fixed to the lower end of the side wall of the collecting part 62. A compression spring 64 fixedly connected to the mounting part 6 is abutted on the upper surface of the movable block 61.

[0031] By adopting the above technical solution, the wastewater entering the outer shell 1 of the device will first be filtered through the filter screen plate 5, thereby filtering out larger particulate impurities in the wastewater. When the transmission pipe 31 rotates, it will drive the mounting part 6 to move, so that the mounting part 6 will drive the collecting part 62 to move synchronously. With the cooperation of the scraper 63, the particulate impurities intercepted on the upper surface of the filter screen plate 5 can be scraped into the collecting part 62, thereby collecting these impurities and reducing the clogging of the filter screen plate 5. Furthermore, under the elasticity of the compression spring 64, the movable block 61 will be pushed to move vertically, so that the scraper 63 can better contact the upper surface of the filter screen plate 5, improving the cleaning effect on impurities.

[0032] Working principle: The PLC controller controls the drive motor 3 to start, which drives the transmission tube 31 to rotate. The wastewater entering the outer shell 1 of the device is first filtered through the filter screen 5 to remove larger particulate impurities. When the transmission tube 31 rotates, it drives the mounting part 6 to move, which in turn drives the collecting part 62 to move. With the cooperation of the scraper 63, the particulate impurities intercepted on the upper surface of the filter screen 5 are scraped into the collecting part 62. The filtered wastewater enters the bottom of the outer shell 1 of the device, and the added medicine also enters the bottom. A fixed bearing 38 is set on the connecting part 34, so that the rotation of the transmission tube 31 does not drive the connecting part 34 to rotate. The rotation of the transmission tube 31 drives the stirring rod 4 to rotate. The wastewater and the chemical solution are then stirred and mixed. The PLC controller controls the air pump 36 to start. The air pump 36 filters the external air through the filter cylinder 37 and draws it in. The air is then transported to the connector 34 through the conveying pipe 35 and enters through the through hole 39 on the transmission pipe 31. It enters the two exhaust components 32 and is sprayed upward through the air outlet 33 on the exhaust component 32, causing bubbles to be generated at the bottom of the wastewater. The rising, diffusion and shearing action of the bubbles provide the necessary conditions for the microbial metabolism, pollutant degradation and homogenization of the wastewater. In addition, the rising flow velocity formed by the rising bubbles is usually 0.3-0.8 m / s, which can drive the wastewater to circulate. With the cooperation of the stirring rod 4, the mixing effect of the chemical solution can be improved.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
