Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to an aeration device for municipal wastewater treatment. Background Technology

[0002] Municipal wastewater is a type of water source with highly variable water quality, making it very difficult to treat. The concentrations of total dissolved solids, COD, BOD, total silica, ammonia, and some other pollutants change very frequently. In addition, the wastewater before treatment contains high concentrations of organic matter and microorganisms. Therefore, it is necessary to use aerators to treat the wastewater in the aeration tank. This refers to the process of forcibly transferring oxygen from the air into the liquid, with the aim of obtaining sufficient dissolved oxygen.

[0003] Existing municipal wastewater treatment methods often rely on aeration devices. By introducing air into the wastewater, air is introduced to promote the degradation of organic matter, the growth of microorganisms, and the increase of dissolved oxygen, thereby purifying the wastewater. However, this often requires placing the aeration heads into the wastewater for contact. Impurities and microbial flocs in the wastewater can clog the micropores of the aeration heads, reducing aeration efficiency and requiring regular maintenance. Furthermore, the disassembly of the internal filter plates in existing aeration heads is relatively difficult, placing a burden on staff. To address these issues, an improved and upgraded aeration device for municipal wastewater treatment is proposed. Utility Model Content

[0004] The purpose of this invention is to provide an aeration device for municipal sewage treatment to solve the problems mentioned in the background art.

[0005] To solve the above problems, the following technical solution is provided: an aeration device for municipal sewage treatment, including a mounting frame, a first motor fixedly mounted on the outer wall of the mounting frame and a threaded screw fixedly connected to the output end of the first motor, a movable bearing plate threadedly connected to the outer wall of the threaded screw, a reciprocating structure above the movable bearing plate, an aeration blower at both ends of the reciprocating structure and an aeration pipe fixedly connected to one end of the aeration blower, an aeration head fixedly connected to one end of the aeration pipe and a filter plate inside the aeration head, and inclined blocks symmetrically fixedly mounted on the outer wall of the filter plate;

[0006] The outer wall of the aeration head is provided with a disassembly structure at the opposite position of the inclined block. The disassembly structure includes two fixing boxes fixedly installed on the outer wall of the aeration head. The inner walls of the two fixing boxes are slidably connected to push rods, and the push rods are fixedly installed on the outer wall of the plug rod. The plug rod is fitted with a buffer spring, and one end of the plug rod is set on the inclined block.

[0007] As a preferred embodiment of the above technical solution, two mounting blocks are symmetrically fixedly installed on the outer wall of the filter plate. The mounting blocks are slidably connected inside the aeration head, and the two inclined blocks are slidably connected inside the aeration head, with positioning holes provided inside the inclined blocks.

[0008] As a preferred embodiment of the above technical solution, the outer wall of the plug rod is slidably connected to a limiting sleeve and the limiting sleeve is fixedly installed inside the fixing box. The buffer spring is located between the limiting sleeve and the push rod. One end of the plug rod passes through the inside of the aeration head and the extended end is inserted into the positioning hole.

[0009] As a preferred embodiment of the above technical solution, the reciprocating structure includes a half gear rotatably mounted on a movable support plate. A limit frame is fixedly provided at the upper end of the movable support plate, and a second motor is fixedly provided at the upper end of the limit frame. One end of the second motor is connected to the half gear.

[0010] As a preferred embodiment of the above technical solution, a gear plate is meshed with the outer wall of the half gear, and a support frame is fixedly provided at both ends of the gear plate, and the aeration blower is fixedly installed on the support frame.

[0011] As a preferred embodiment of the above technical solution, two limiting blocks are symmetrically arranged at the bottom of the movable support plate and the limiting blocks are slidably connected to the mounting frame, and two guide sliders are fixedly arranged at the bottom of the gear plate and the guide sliders are slidably connected to the upper end of the movable support plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model device includes components such as an aeration head, a filter plate, a push rod, a buffer spring, a plug-in rod, and a limiting sleeve. By pulling the pull rods on both sides, the plug-in rod is forced to compress the buffer spring on the limiting sleeve, causing it to deform. This displaces the plug-in rod from the positioning hole on the inclined block. Then, the filter plate is slid out using the mounting block for easy cleaning. Conversely, the principle is the same, pressing the filter plate into the aeration head and causing the inclined block and plug-in rod to interlock. This improves the aeration efficiency of the aeration head, avoids problems such as impurities and microbial flocs in the sewage clogging the micropores of the aeration head, and improves the stability of use.

[0014] 2. The device of this utility model is equipped with components such as a threaded screw, a movable bearing plate, a half gear, a gear plate, and a guide slider. The threaded screw drives the movable bearing plate to move left and right, and at the same time drives the second motor to drive the aeration blower on the half gear meshing with the gear plate to move back and forth, thereby driving the aeration head to move back and forth to treat the sewage in the aeration tank. This facilitates uniform aeration at different positions in the tank and greatly improves the uniformity of the aeration process.

It should be understood that the embodiments of the present invention are not limited in scope. Within the spirit and scope of the appended claims, the embodiments of the present invention include many changes, modifications, and equivalents. Attached Figure Description

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figures 1 to 6As shown, an aeration device for municipal sewage treatment includes a mounting frame 1. A first motor 2 is fixedly mounted on the outer wall of the mounting frame 1, and a threaded screw 21 is fixedly connected to the output end of the first motor 2. A movable bearing plate 22 is threadedly connected to the outer wall of the threaded screw 21. A reciprocating structure 4 is arranged above the movable bearing plate 22. An aeration blower 5 is arranged at both ends of the reciprocating structure 4, and an aeration pipe 6 is fixedly connected to one end of the aeration blower 5. An aeration head 7 is fixedly connected to one end of the aeration pipe 6, and a filter plate 9 is arranged inside the aeration head 7. Inclined blocks 92 are symmetrically fixedly arranged on the outer wall of the filter plate 9.

[0026] The outer wall of the aeration head 7 is provided with a disassembly structure 8 located opposite to the inclined block 92. The disassembly structure 8 includes two fixing boxes 81 fixedly installed on the outer wall of the aeration head 7. The inner walls of the two fixing boxes 81 are slidably connected to push rods 82, and the push rods 82 are fixedly installed on the outer wall of the plug rod 83. The plug rod 83 is fitted with a buffer spring 84, and one end of the plug rod 83 is set on the inclined block 92.

[0027] like Figures 3 to 4 As shown, two mounting blocks 91 are symmetrically fixedly installed on the outer wall of the filter plate 9. The mounting blocks 91 are slidably connected to the inside of the aeration head 7. Two inclined blocks 92 are slidably connected to the inside of the aeration head 7, and positioning holes 93 are opened inside the inclined blocks 92. The outer wall of the plug rod 83 is slidably connected to the limiting sleeve 85, and the limiting sleeve 85 is fixedly installed inside the fixing box 81. The buffer spring 84 is located between the limiting sleeve 85 and the push rod 82. One end of the plug rod 83 passes through the inside of the aeration head 7 and the extended end is inserted into the positioning hole 93.

[0028] The inclined block 92 is designed to be compatible with the aeration head 7. When one end of the plug rod 83 slides on the inclined block 92, a gentle squeeze on the filter plate 9 will allow the plug rod 83 to be directly inserted into the positioning hole 93 on the inclined block 92. This facilitates easy disassembly and cleaning of the filter plate 9 and prevents the aeration head 7 from becoming clogged, which would affect the uniformity of aeration. The aeration head 7 releases air evenly into the wastewater in the form of tiny bubbles, increasing the contact area between air and wastewater, improving oxygen transfer efficiency, and providing a suitable living environment for aerobic microorganisms in the wastewater. This allows them to efficiently decompose pollutants such as organic matter and ammonia nitrogen in the wastewater, thereby purifying the wastewater.

[0029] like Figures 5 to 6As shown, the reciprocating structure 4 includes a half gear 42 rotatably mounted on a movable support plate 22. A limit frame 3 is fixedly installed on the upper end of the movable support plate 22, and a second motor 41 is fixedly installed on the upper end of the limit frame 3. One end of the second motor 41 is connected to the half gear 42. A gear plate 43 is meshed with the outer wall of the half gear 42. Support frames are fixedly installed at both ends of the gear plate 43. An aeration blower 5 is fixedly installed on the support frame. Two limit blocks 23 are symmetrically arranged at the bottom of the movable support plate 22, and the limit blocks 23 are slidably connected to the mounting frame 1. Two guide sliders 44 are fixedly arranged at the bottom of the gear plate 43, and the guide sliders 44 are slidably connected to the upper end of the movable support plate 22.

[0030] By setting limit blocks 23 and guide sliders 44 at the bottom of the movable support plate 22 and gear plate 43 respectively, relative limiting is facilitated during movement. The gear plate 43 reciprocates under the meshing of the half gear 42, thereby driving the two aeration heads 7 to reciprocate against the aeration tank, uniformly spraying purification at all positions in the aeration tank. Furthermore, the half gear 42 and gear plate 43 are matched in position.

[0031] The working principle and process of this utility model are as follows: First, the mounting frame 1 is installed in the middle of the upper part of the aeration tank. Then, the external power supply is connected, and the first motor 2 drives the threaded screw 21 to rotate on the mounting frame 1. This causes the moving support plate 22 to move slowly using the limiting block 23 to slide and limit the gear plate 43 above. At the same time, the second motor 41 on the limiting frame 3 is simultaneously turned on, causing the half gear 42 to rotate stably on the moving support plate 22. The half gear 42 drives the two aeration blowers 5 on the gear plate 43 to move back and forth. The aeration blowers 5 provide an air source, pressurize the air and deliver it to the aeration pipeline 6. The aeration pipeline 6 is responsible for distributing the air to the sewage treatment tank, causing the aeration heads 7 to release the air evenly into the sewage in the form of tiny bubbles. The aeration system now provides uniform aeration at different locations within the aeration tank, significantly improving the uniformity of the aeration process. However, the aeration head 7 is prone to clogging from impurities in the aeration tank after prolonged use. By pulling the push rod 82 on both sides of the fixed box 81, the push rod 82 causes the insertion rod 83 to press against the buffer spring 84 on the limiting sleeve 85. Then, the filter plate 9 slides off the aeration head 7 using the mounting block 91, facilitating quick disassembly and cleaning. When installation is required, simply align the two mounting blocks 91 on the filter plate 9 with the groove on the aeration head 7, causing the two inclined blocks 92 to press against the insertion rod 83. The insertion rod 83 is then engaged with the positioning hole 93 by the spring force of the buffer spring 84, facilitating quick installation of the filter plate 9 and regular cleaning of the aeration head 7, thus improving aeration uniformity.

[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
