Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, and in particular to an adjustable aeration device for sewage treatment. Background Art

[0002] In the sewage treatment process, aeration is a key link. Its purpose is to fill the sewage with air so that the organic matter in the sewage can fully contact with the microorganisms, promote the metabolism of the microorganisms, and thus decompose the pollutants in the sewage. Traditional aeration devices usually have a simple structure, limited aeration effect, and are difficult to adapt to changes in different water quality and treatment requirements. For example, the aeration range of some aeration devices is fixed and cannot be flexibly adjusted according to the shape and size of the sewage pool, resulting in insufficient aeration in some areas and excessive aeration in some areas, affecting the treatment efficiency and effect. At the same time, sewage often contains various impurities, such as floating objects, sediments, etc. These impurities can easily clog the aeration equipment, reduce the service life and operating stability of the equipment, and traditional devices lack effective solutions to deal with impurity problems. Therefore, it is necessary to develop a new type of aeration device to overcome the above problems. Summary of the invention

[0003] Overall structure of the device

[0004] The adjustable aeration device for sewage treatment of the present invention mainly comprises an aeration tank and an aeration pipe. The aeration pipe is inserted at the center of the aeration tank, and four aeration branches are evenly distributed at the outer peripheral position of the bottom end. The aeration branches are hinged with a connecting frame near one end of the aeration pipe, and the connecting frame is fixed to the same lower mounting seat, and the lower mounting seat is sleeved on the outer peripheral surface of the bottom of the aeration pipe. A bearing is sleeved on the outer peripheral surface of the upper part of the aeration pipe, and a driven gear and a runner are sleeved on the outer peripheral surface of the bearing.

[0005] Cleaning components

[0006] The cleaning assembly is used to clean the impurities inside the aeration tank, and includes rotating brackets symmetrically arranged at both ends of the outer circumference of the runner. A filter frame is provided at the bottom of the rotating bracket, one end of the filter frame is open to facilitate the collection of impurities, and the other end is provided with a number of filter holes, through which floating impurities on the surface of sewage can be filtered out to prevent them from entering the aeration system and causing blockage or affecting the aeration effect.

[0007] Joint swing assembly

[0008] The combined swing assembly is used to control the up and down swing of the aeration branch pipe to improve the aeration effect. It includes a first bevel gear coaxially arranged at the bottom of the runner, and four second bevel gears are meshed equidistantly on the outer side of the lower part of the first bevel gear. A rotating shaft is inserted in the center of each of the second bevel gears, and the rotating shaft is hinged to the outer circumference of the aeration pipe. A turntable is coaxially sleeved at the end of the rotating shaft, and a connecting rod is hinged at the eccentric position of the side wall of the turntable. A pull rod is hinged at the bottom of the connecting rod, and the bottom end of the pull rod is hinged to the end of the aeration branch pipe on the adjacent side. A hose is provided at the bottom of the aeration branch pipe, and the hose is connected to the inside of the aeration pipe to ensure the stability of the gas supply during the swinging of the aeration branch pipe.

[0009] Adjustment components

[0010] The adjustment assembly is used to control the installation height of the filter frame to meet the needs of cleaning sewage impurities at different depths. It includes an adjustment rod that is arranged on the top of the filter frame, and a number of pin holes that are equidistantly opened on the rotating bracket. The adjustment rods are slidably inserted into the pin holes, and a positioning assembly is provided on the upper part of the adjustment rod. The positioning assembly includes a first clamp and a second clamp hinged to the upper part of the adjustment rod, and the first clamp and the second clamp are both sleeved on the outer circumferential surface of the rotating bracket. Two bolts are slidably inserted at the end of the first clamp, and nuts are threadedly sleeved on the bolts, and the nuts are abutted against the end of the second clamp. Two notches are provided at the end of the second clamp for the bolts to pass through. A slider is provided at the bottom of the adjustment rod, and a dovetail groove for adapting the slider is provided on the top of the filter frame to facilitate the installation and disassembly of the filter frame and the adjustment rod.

[0011] Other auxiliary parts

[0012] The ends of the aeration branch pipes are all equipped with aeration heads to evenly disperse the air into the sewage. An upper mounting seat is sleeved on the upper part of the aeration pipe, a motor is arranged at the bottom of the upper mounting seat, and a driving gear is coaxially arranged at the output end of the bottom of the motor. The driving gear meshes with the driven gear to provide a power source for the operation of the entire device.

[0013] Beneficial Effects

[0014] 1. Through the combined swing assembly, the rotation of the impeller can be converted into the up and down swing of the aeration branch pipe, so that the aeration head can be aerated at different heights, increasing the coverage and uniformity of aeration, and improving the contact efficiency between sewage and air, thereby improving the effect and speed of sewage treatment.

[0015] 2. The setting of the cleaning component effectively solves the impact of impurities in sewage on the aeration device. The filter frame rotates continuously under the drive of the impeller, which can filter out floating impurities on the surface of sewage in time to prevent them from entering the aeration system, reducing the risk of equipment blockage and extending the service life of the equipment. It also helps to keep the water quality in the aeration tank relatively clean, which is conducive to the stability of the overall sewage treatment process.

[0016] 3. The adjustment component allows the installation height of the filter frame to be flexibly adjusted according to actual needs. For sewage of different depths and different impurity contents, the filter frame can be operated at the most suitable height by changing the position of the adjustment rod in the pin hole and fixing it with the positioning component, further improving the adaptability and versatility of the device to different sewage treatment conditions.

[0017] In summary, the adjustable aeration device for sewage treatment of the present invention integrates multiple functions such as efficient aeration, impurity cleaning and height adjustment through a unique structural design, effectively solves many problems existing in traditional aeration devices, has significant innovation and practicality, and has broad application prospects in the field of sewage treatment technology.

[0030] Example 1

[0031] See also Figures 1 to 6

[0032] 1. Assembly and initial setup of the device

[0033] First, the aeration pipe 1 is vertically inserted in the center of the aeration tank 30 to ensure that it is firmly installed. Four aeration branch pipes 2 are installed at equal distances at the outer peripheral position of the bottom end of the aeration pipe 1. Each aeration branch pipe 2 is hinged at one end close to the aeration pipe 1 through a connecting frame 29. The connecting frame 29 is fixed to the same lower mounting seat 25, and the lower mounting seat 25 is tightly sleeved on the outer peripheral surface of the bottom of the aeration pipe 1.

[0034] A bearing 5 is sleeved on the outer circumference of the upper part of the aeration pipe 1, and a driven gear 6 and a runner 7 are sleeved on the outer circumference of the bearing 5 in sequence, ensuring that all components are tightly installed and can rotate smoothly.

[0035] For the installation of the filter frame 12, the dovetail groove 14 on the top of the filter frame 12 is docked with the slider 15 at the bottom of the adjusting rod 31 and slidably installed to preliminarily connect the filter frame 12 with the rotating bracket 11. Then adjust the height of the filter frame 12 according to actual needs, insert the adjusting rod 31 into the pin hole 26 at a suitable position on the rotating bracket 11, rotate the first clamp 16 and the second clamp 27 to cover the outer peripheral surface of the rotating bracket 11, pass the bolt 17 through the notch 28 at the end of the second clamp 27 and dock with the second clamp 27, then put the nut 18 on the outside of the bolt 17 and tighten it to make it abut against the second clamp 27, and complete the fixing of the height of the filter frame 12.

[0036] An aeration head 4 is installed at the end of the aeration branch pipe 2, an upper mounting seat 9 is sleeved on the upper part of the aeration pipe 1, a motor 10 is installed at the bottom of the upper mounting seat 9, and the coaxial driving gear 8 at the output end at the bottom of the motor 10 is correctly meshed with the driven gear 6.

[0037] 2. Operation process of the device

[0038] The motor 10 is started, and the motor 10 drives the driving gear 8 to rotate. The meshing action of the driving gear 8 and the driven gear 6 causes the driven gear 6 and the rotating wheel 7 to rotate synchronously.

[0039] When the wheel 7 rotates, the rotating brackets 11 at both ends of its outer circumference rotate accordingly, thereby driving the filter frame 12 to make a circular motion above the water surface of the aeration tank 30. In this process, the filter frame 12 filters and collects impurities floating on the water surface through a plurality of filter holes 13 opened at one end thereof, thereby preventing the impurities from interfering with the aeration process or clogging the aeration equipment.

[0040] At the same time, the first bevel gear 19 at the bottom of the impeller 7 rotates synchronously with the impeller 7. The first bevel gear 19 interacts with the four second bevel gears 21 meshed with each other at equal distances, driving the rotating shaft 20 at the center of the second bevel gear 21 to rotate, and the turntable 22 at the end of the rotating shaft 20 also rotates. Since a connecting rod 23 is hinged at an eccentric position on the side wall of the turntable 22, and a pull rod 24 hinged at the bottom end of the connecting rod 23 is connected to the end of the aeration branch pipe 2, the rotation of the turntable 22 causes the top of the connecting rod 23 to perform a circular motion, thereby driving the pull rod 24 to perform a regular up and down motion, and then pulling the end of the aeration branch pipe 2 to swing up and down. The bottom of the aeration branch pipe 2 is connected to the inside of the aeration pipe 1 through the hose 3, so the aeration head 4 at the end of the aeration branch pipe 2 will change the aeration position and angle as the aeration branch pipe 2 swings up and down, making the aeration more uniform and efficient, enhancing the contact effect between sewage and air, and improving the sewage treatment efficiency.

[0041] The connection parts between the connecting rod 23, the rotating disk 22 and the pulling rod 24 all adopt a rotatable and sealed connection structure to ensure that in an underwater environment, when the connecting rod 23 drives the pulling rod 24 to move, no water leakage will occur, thereby ensuring the stable operation of the device and the normal progress of the aeration process.

[0042] During the whole sewage treatment process, the adjustable aeration device operates continuously, and the aeration environment is kept relatively clean through the filtering effect of the filter frame 12, and the aeration effect is optimized through the up and down swing of the aeration branch pipe 2, so as to achieve effective sewage treatment. In addition, the height of the filter frame 12 and the operating parameters of the motor 10 can be flexibly adjusted according to the actual sewage treatment conditions, such as the impurity content in the sewage, the aeration demand, etc., to achieve the best treatment effect.

[0043] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0044] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
