Description

Technical Field

[0001] The utility model relates to the technical field of aeration devices, in particular to an anti-clogging sewage treatment aeration device. Background Art

[0002] The sewage treatment technology in anti-clogging is a complex and important field, in which the aeration device plays a key role.

[0003] The working principle of the aeration equipment is mainly to inject sufficient oxygen into the sewage, and at the same time has the function of stirring the water body, helping the oxygen to fully blend and diffuse in the sewage, creating an oxygen-rich and uniform living environment for the microbial community, so as to improve the sewage purification and treatment efficiency.

[0004] In the prior art, a disclosed anti-clogging sewage treatment aeration device with the patent number CN202323332967.3 aerates the sewage inside the aeration tank by arranging an air pipe at the bottom of the aeration tank, and realizes the automatic lifting of the air pipe by arranging a motor device in the middle of the aeration tank. The air pipe is arranged in the middle of the aeration tank, and a large number of agitated bubbles are generated during operation. When approaching the positions of multiple groups of blades, the bubbles will agitate the blades to move outside the vertical rod, so as to disturb the sewage inside the aeration tank, and promote the aeration tank with calm precipitation to spread the range of bubbles generated by aeration under the movement of the blades, so as to fully treat the sewage inside the aeration tank.

[0005] However, when the above-mentioned aeration tank is in use, the air pipe head is installed downward at the bottom of the aeration tank, and it is not easy to clean the aeration head. Moreover, due to the placement of the motor in the middle, the number of air pipes installed is also limited, and the cleaning efficiency is also affected to a certain extent, resulting in uneven cleaning.

[0006] At the same time, the lifting device in this technology is directly exposed in the aeration tank, which is relatively easy to be corroded, affecting its product life. At the same time, the aeration head of this device is not detachable, which is not conducive to cleaning. Therefore, it does not meet the existing requirements, and for this reason, we propose an anti-clogging sewage treatment aeration device. Content of the Utility Model

[0007] The purpose of the utility model is to provide an anti-clogging sewage treatment aeration device to solve the problems mentioned in the above background art, that is, when the above-mentioned aeration tank is in use, the aeration head is downward and not detachable, which is not convenient to clean the aeration head. After long-term use, the through holes on its surface are easy to be blocked, affecting the aeration effect of the aeration head, etc. At the same time, the lifting motor is in the middle of the air pipe, the space utilization rate is not high, and it is easy to be corroded, affecting the service life.

[0008] To achieve the above object, the present utility model provides the following technical solution: An anti-blocking sewage treatment aeration device, including an aeration tank, inside which a connecting plate is movably connected through a lifting mechanism, and a plurality of aeration pipes are evenly installed on the opposite sides of the outer surfaces of the two connecting plates.

[0009] Above the aeration pipes, a plurality of connecting pipes are evenly arranged. A sleeve is fixedly sleeved above the connecting pipes. On the upper sides of both inner walls of the sleeve, strip-shaped grooves are provided. Inside the strip-shaped grooves, strip-shaped blocks are movably arranged through a disassembly mechanism. On the opposite sides of the outer surfaces of the two strip-shaped blocks, a filter net is fixedly connected. Above the outer surface of the sleeve, an aeration head is sleeved, and the aeration pipes of this device can rotate.

[0010] Preferably, the lifting mechanism includes a threaded rod, which is arranged through vertical grooves at the front and back of both inner walls of the aeration tank. A threaded block is sleeved on the outer surface of the threaded rod, and the outer surface of the threaded block is fixedly connected to the outer surface of the connecting plate. Of course, the lifting mechanism is not limited to screw lifting, and it can also be a structure lifted by air pressure or hydraulic pressure.

[0011] Preferably, at the four end corners of the bottom of the aeration tank, motors are installed through motor cavities. The output end of the motor is fixedly connected to a short shaft, the upper end surface of the short shaft is fixedly connected to the lower end surface of the threaded rod, and the upper end surface of the threaded rod is rotatably connected to the inner wall of the vertical groove through a bearing.

[0012] Preferably, the connecting pipe is threadedly connected to the aeration pipe, the aeration pipe is connected to an external air pump through a telescopic hose, the aeration head is threadedly connected to the sleeve, and a plurality of aeration holes are evenly arranged on the upper end surface of the aeration head.

[0013] Preferably, the aeration pipe is movably connected to the connecting plate and can rotate. When the aeration head is placed downward for aeration, and when it needs to be cleaned, rotating the aeration head upward makes it easier to clean.

[0014] Preferably, the disassembly mechanism includes insertion rods, which are arranged through through holes on both sides of the sleeve. A spring A is sleeved on the outer surface of the insertion rods, and insertion holes are provided on the opposite sides of the outer surfaces of the two strip-shaped blocks.

[0015] Preferably, the insertion holes are adapted to the insertion rods. A spring B is fixedly installed on the upper end surface of the strip-shaped groove. Grooves are provided on the opposite sides of the two through holes, and pull rings are installed on the opposite sides of the outer surfaces of the two insertion rods.

[0016] Compared with the prior art, the beneficial effects of the present utility model are:

[0017] The utility model is provided with a lifting mechanism and a disassembly mechanism. By controlling the switch of the motor, the motor can drive the short shaft to rotate, thereby driving the threaded rod to rotate. The threaded block can move upward on the outer surface of the threaded rod, driving the connecting plate to move upward, and then driving the aeration pipe and the aeration head to move upward, which is convenient for the staff to operate.

[0018] The aeration pipe is movably connected to the connecting plate and can rotate. When the aeration head is placed downward, aeration is carried out. When it needs to be cleaned, the aeration head rotates upward, making it easier to clean.

[0019] The disassembly and cleaning of this device are more convenient. During operation, first unscrew the connecting pipe from the aeration pipe, and then unscrew the aeration head from the sleeve, exposing the sleeve and the filter screen. By pulling the two insertion rods outward simultaneously through the pull ring, the insertion rods leave the inner side of the insertion holes. Under the action of the spring B, the strip-shaped block is pushed upward into the strip-shaped groove. The staff can remove the filter screen from the sleeve, clean the filter screen, and then install it inside the sleeve after cleaning.

[0020] The utility model is provided with a filter screen, and the filter screen is convenient for disassembly and cleaning, thereby avoiding blockage of the aeration head and ensuring the aeration effect.

[0021] The utility model installs the motor at the four corners of the aeration tank, avoiding the risk that the lifting device is directly exposed and easily corroded, improving the service life of the product. At the same time, more aeration pipes can be set, improving the aeration effect. Placing the motor device around makes the space utilization more reasonable, and more aeration pipes can be installed to improve the aeration efficiency. Description of the Drawings

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0028] Aeration technology is an important link in the sewage treatment process to provide sufficient oxygen to promote the decomposition of pollutants by microorganisms. In recent years, with the rapid development of technology, aeration equipment has been widely used in the sewage treatment field at home and abroad due to its characteristics of low energy consumption and high energy efficiency.

[0029] Aeration refers to artificially introducing air into the sewage treatment tank through equipment, so that the liquid in the tank contacts the air for oxygenation, and by agitating the liquid, the purpose of accelerating the transfer of oxygen into the liquid is achieved. By increasing the oxygen content in the sewage, the anaerobic bacteria in the sewage are reduced. The selection and application of these devices need to be comprehensively considered according to factors such as the nature of the sewage, the treatment efficiency requirements, and the cost-benefit.

[0030] In short, the sewage treatment aeration device in anti-blockage is the key to achieving efficient and energy-saving sewage treatment. It is necessary to reasonably select and optimize the application of aeration equipment according to the specific engineering requirements and sewage characteristics to achieve the best treatment effect.

[0031] The motor (model 68KTYZ) mentioned in the present utility model can be obtained by purchasing from the market or customizing privately. The 68KTYZ model motor is an AC permanent magnet synchronous motor with a forward and reverse rotation function, suitable for a variety of automatic control and low-speed operation equipment, such as the 68KTYZ capacitor split-phase reversible claw pole permanent magnet synchronous motor. This motor can rotate in two directions, clockwise and counterclockwise, and is suitable for a variety of application scenarios, such as instruments and meters, automatic control, etc.

[0032] The power of the motor is 28W, the shaft diameter is 7mm, and the selectable speed range is from 2.5 rpm to ~110 rpm. Different speeds can be selected according to needs. Of course, it is not limited to this one kind of motor, and the motor can adopt commonly used small lifting motors on the market.

[0033] There can also be many choices for the material of the aeration tank 1. The material selection of the sewage treatment aeration tank has an important impact on the aeration efficiency and the durability of the equipment.

[0034] When selecting the material of the aeration tank 1, factors such as the specific requirements of sewage treatment, aeration efficiency, durability of the equipment, corrosion resistance, and cost-benefit need to be considered.

[0035] Meanwhile, the maintenance and cleaning of the aeration tank 1 are also important aspects to consider to ensure long-term effective operation. The main materials of aerators currently in use can be classified into the following categories: ceramic corundum. Aerators of this material were once widely used, but because the pores are prone to fouling, resulting in an increase in head loss, they are now less used in some areas; membrane aerators are the current mainstream choice. The core part lies in the aeration membrane itself. The material of the membrane is usually selected as EPDM (ethylene propylene diene monomer), which is particularly suitable for biological sewage treatment due to its durability, lifespan, anti-aging, and hydrophilicity characteristics; silicone rubber. Although the performance of aerators made of silicone rubber may be inferior to that of EPDM, it is also an option, especially when there are chemical substances such as hydrocarbons and aromatics in the sewage, and the use of silicone rubber aerators may need to be considered; metal materials. In some cases, stainless steel or other metal materials may be used for the aeration equipment to improve the durability and corrosion resistance of the equipment; plastic materials. Some aeration equipment may use plastic materials.

[0036] Please refer to Figures 1 to 4 As shown in, an embodiment provided by the present utility model: an anti-blocking sewage treatment aeration device, including an aeration tank 1. A connecting plate 5 is movably connected inside the aeration tank 1 through a lifting mechanism 4. A plurality of aeration pipes 2 are evenly installed on the opposite sides of the outer surfaces of the two connecting plates 5. A plurality of connecting pipes 8 are evenly arranged above the aeration pipes 2. A sleeve 6 is fixedly sleeved above the connecting pipes 8. Bar-shaped grooves 10 are arranged on both sides of the upper part of the inner wall of the sleeve 6. Bar-shaped blocks 11 are movably arranged inside the bar-shaped grooves 10 through a disassembly mechanism. A filter screen 7 is fixedly connected to the opposite sides of the outer surfaces of the two bar-shaped blocks 11. An aeration head housing 9 is sleeved above the outer surface of the sleeve 6.

[0037] The aeration pipe 2 is movably connected to the connecting plate and can rotate. When the aeration head 3 is placed downward for aeration, when cleaning is required, the aeration head 3 rotates upward, making it easier to clean.

[0038] The separate arrangement of the aeration heads 3 means that during sewage treatment or water body aeration, multiple aeration heads are arranged in the aeration tank or water body according to a certain rule and spacing to achieve more efficient and uniform oxygen transfer and mixing.

[0039] The following are the key points of the separate arrangement of the aeration heads 3 in this embodiment: Uniformity. In this embodiment, the aeration heads 3 are evenly distributed on the aeration pipes. The aeration pipes 2 are arranged horizontally at the bottom of the aeration tank. The separate arrangement can ensure that the oxygen distribution in the entire aeration area is more uniform, avoiding local oxygen supersaturation or deficiency. A reasonable arrangement can improve the oxygen transfer efficiency, increase the dissolved oxygen concentration in the water, and thus improve the sewage treatment effect. According to different aeration requirements and tank structures, the arrangement method of the aeration heads 3 can be adjusted, such as linear arrangement, spiral arrangement, grid arrangement. The separate arrangement is adopted in this embodiment, but of course, it is not limited to this arrangement.

[0040] The aeration heads 3 arranged separately are convenient for inspection and maintenance. When it is necessary to replace or clean the aeration heads 3, it can be carried out individually without affecting the operation of other aeration heads; the arrangement of the aeration heads 3 can be adjusted according to the flow characteristics of the water body and the requirements of the sewage treatment process to adapt to different treatment conditions; by optimizing the arrangement of the aeration heads 3, unnecessary energy consumption can be reduced, and more energy-efficient sewage treatment can be achieved; in some cases, the aeration heads 3 can be designed modularly to facilitate increasing or decreasing the number of aeration heads 3 or adjusting the arrangement according to actual needs; the separate arrangement helps to reduce the risk of blockage of the aeration heads 3 because the aeration area of each aeration head 3 is relatively small, reducing the possibility of blockage; a reasonable arrangement can enhance the mixing effect of the water body, promote the contact between pollutants and microorganisms, and improve the biochemical treatment efficiency.

[0041] In this embodiment, the lifting mechanism 4 includes a threaded rod 401. The threaded rod 401 is arranged on the front and rear sides of the inner walls on both sides of the aeration tank 1 through vertical slots 402. A threaded block 403 is sleeved on the outer surface of the threaded rod 401, and the outer surface of the threaded block 403 is fixedly connected to the outer surface of the connecting plate 5.

[0042] Of course, the lifting mechanism is not limited to screw lifting, and it can also be a structure that lifts through air pressure or hydraulic pressure.

[0043] The following lifting mechanism methods can also be adopted in this embodiment. The following are some common types of lifting mechanisms: Hydraulic lifting mechanism: Uses a hydraulic cylinder as the power source and realizes lifting through the pressure of hydraulic oil; Electric lifting mechanism: Uses an electric motor as the power source and realizes lifting through transmission devices such as gears, belts or lead screws; Pneumatic lifting mechanism: Uses compressed air as the power source and realizes lifting through a cylinder; Screw lifting mechanism: Uses a screw mechanism (such as a ball screw or trapezoidal screw) to realize lifting, with the characteristic of high positioning accuracy; Gear and rack lifting mechanism: Realizes linear motion through the meshing of a gear and a rack, and is commonly used in large lifting platforms; Slide rail lifting mechanism: Realizes lifting through a slider sliding on a guide rail, suitable for occasions with heavy loads; Chain lifting mechanism: Uses a chain as the transmission element and realizes lifting through a sprocket drive; Slide block lifting mechanism: Realizes lifting through a slider sliding on a vertical slideway, with a simple structure; Stepper motor lifting mechanism: Uses a stepper motor as the driving force and realizes precise lifting by controlling the number of steps of the motor; Servo motor lifting mechanism: Uses a servo motor as the driving force and can realize high-speed and high-precision lifting.

[0044] Motors are installed at the four end corners of the bottom of the aeration tank 1 through motor cavities. The output end of the motor is fixedly connected to a short shaft, the upper end surface of the short shaft is fixedly connected to the lower end surface of the threaded rod 401, and the upper end surface of the threaded rod 401 is rotationally connected to the inner wall of the vertical slot 402 through a bearing. When the motor works, it can drive the short shaft to rotate, thereby driving the threaded rod 401 to rotate.

[0045] The connecting pipe 8 is threadedly connected to the aeration pipe 2. The aeration pipe 2 is connected to an external air pump through a telescopic hose. The aeration head housing 9 is threadedly connected to the sleeve 6. Multiple aeration holes are evenly arranged on the upper end surface of the aeration head 9, which facilitates screwing the connecting pipe 8 off the aeration pipe 2. During the upward movement of the aeration pipe 2, the telescopic hose is stretched, which will not affect the movement of the aeration pipe 2 and facilitates screwing the aeration head 9 off the sleeve 6.

[0046] In this embodiment, there are also various implementation forms for the arrangement of the aeration holes. The arrangement of the aeration holes needs to be comprehensively considered according to factors such as the size, shape, water depth, water flow characteristics, and pollutant load of the aeration tank to achieve the best aeration effect and sewage treatment efficiency. At the same time, the arrangement of the aeration holes can also be combined with the aeration control system to achieve intelligent aeration management. The arrangement of the aeration holes has an important impact on the aeration effect and sewage treatment efficiency.

[0047] The following are some common arrangements of the aeration holes: Linear arrangement: The aeration holes are evenly distributed along a straight line, which can ensure uniform aeration; Grid arrangement: The aeration holes are arranged in a grid pattern, forming multiple square or rectangular areas; Spiral arrangement: The aeration holes are arranged along a spiral line, which can improve the mixing effect of the water body; Staggered arrangement: The aeration holes are arranged staggered at a certain interval, which can reduce the mutual interference of the bubbles and improve the oxygen dissolution rate; Circular arrangement: A circular arrangement of aeration holes is formed at the center or edge; Radial arrangement: The aeration holes are arranged radially outward from the center; Random arrangement: The aeration holes are randomly distributed in the aeration tank; Group arrangement: The aeration holes are divided into several groups, and each group is arranged according to a certain rule. In this embodiment, the aeration holes are arranged radially outward from the center.

[0048] The disassembly mechanism includes a plug rod 14. The plug rod 14 is arranged on both sides of the sleeve 6 through through holes 12. A spring A 13 is sleeved on the outer surface of the plug rod 14. Jack holes 16 are provided on the opposite sides of the outer surfaces of the two strip-shaped blocks 11.

By pulling the pull rings, the plug rod 14 can be driven to move, and the plug rod 14 can be inserted into the inner side of the jack hole 16.

[0049] A disassembly structure is provided inside the aeration head 3. When this sewage treatment aeration device for preventing blockage is in use, through the setting of the lifting mechanism 4 and the disassembly mechanism, by controlling the switch of the motor, the motor can drive the short shaft to rotate, thereby driving the threaded rod 401 to rotate. The threaded block 403 can move upward on the outer surface of the threaded rod 401, driving the connecting plate 5 to move upward, thereby driving the aeration pipe 2 and the aeration head 3 to move upward, facilitating the operation of the staff.

[0050] During operation, first unscrew the connecting pipe 8 from the aeration pipe 2, and then unscrew the aeration head housing 9 from the sleeve 6 to expose the sleeve 6 and the filter screen 7. Pull the two insertion rods 14 outward simultaneously through the pull ring.
