Description

Technical Field

[0001] The utility model relates to the technical field of domestic sewage treatment, in particular to a domestic sewage biological treatment device. Background Art

[0002] Biological treatment of domestic sewage is a measure or technology that uses the ability of certain organisms to absorb and degrade pollutants to purify sewage. It mainly relies on the decomposition of microorganisms to convert organic matter in sewage into simple inorganic matter, so that sewage can be purified. According to the demand for oxygen, it can be divided into two categories: anaerobic biological treatment and aerobic biological treatment. In the process of biological treatment of sewage, an aeration tank is needed to aerate the sewage to facilitate the rapid reproduction of microorganisms in the sewage.

[0003] It is necessary to install an aeration pipe inside the existing aeration tank, and then install an aeration plate outside the aeration pipe to achieve aeration. However, during the installation of the aeration plate, two limit sleeves are usually used to be set on the outside of the aeration pipe, and then the bolts are installed. Since a large number of aeration plates need to be installed inside a single aeration tank, this installation method is very cumbersome and time-consuming. Therefore, the utility model provides a domestic sewage biological treatment device to meet the needs. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a biological treatment device for domestic sewage, so as to solve the problem that during the installation of the aeration disc, two limit sleeves are usually used to be arranged on the outside of the aeration pipe, and then the bolts are installed. Since a large number of aeration discs need to be installed inside a single aeration tank, this installation method is very cumbersome and time-consuming.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0006] A domestic sewage biological treatment device comprises an aeration tank body, the interior of which is fixedly connected with an aeration pipe, and the exterior of which is provided with a plurality of aeration plates; a fixing assembly, which is used for quickly installing the aeration plates and is connected to the aeration plates; and a sealing assembly, which is used for improving the sealing effect between the aeration plates and the aeration pipe, and is connected to the fixing assembly.

[0007] Optionally, a fixing sleeve is fixedly connected to the outside of the aeration tube, and the fixing assembly includes a fixing base clamped on the outside of the fixing sleeve, both ends of the fixing base are rotatably connected to fixing plates, the interiors of the two fixing plates are in contact with the outside of the aeration tube, and a cavity is opened at the connection of the bottom ends of the two fixing plates, a support plate is provided inside the cavity at the bottom end of one of the fixing plates, a guide plate is provided on the side of the support plate facing the other fixing plate, a limiting column is provided inside the cavity at the bottom end of the other fixing plate, a clamping sleeve is provided on the side of the bottom end of one of the fixing plates facing the other fixing plate, and a clamping groove adapted to the clamping sleeve is opened at the bottom end of the other fixing plate.

[0008] Optionally, the fixing plate is in the shape of an arc-shaped corrugated plate, and an arc-shaped plate is provided on each arc-shaped convex surface of the fixing plate that contacts the aeration pipe.

[0009] Optionally, one side of the guide plate is arc-shaped, and the outward side of the limiting column is also arc-shaped.

[0010] Optionally, a threaded column is fixedly connected to the top of the fixed base, an air guide cavity is opened inside the threaded column, the air guide cavity is fixedly connected to the fixed sleeve, and an aeration plate is installed outside the threaded column located at the air guide cavity through a nut.

[0011] Optionally, the sealing assembly includes an inner cavity opened inside the fixed base, and a plurality of annular cavities are opened inside the fixed base, and the annular cavities are communicated with the inner cavity.

[0012] Optionally, a connection groove is provided on the contact surface between the fixed base and the aeration pipe, a sealing gasket is fixedly connected inside the connection groove, and the top of the sealing gasket is in contact with the annular cavity.

[0013] Optionally, the bottom of the sealing gasket is consistent with the shape of the outside of the aeration pipe.

[0014] Optionally, an arc-shaped cavity is provided between the arc-shaped plate and the fixing plate.

[0015] Optionally, a wide-mouthed arc groove extending inwards is provided on the contact surface between the annular cavity and the inner cavity.

[0016] Compared with the prior art, the utility model has at least the following beneficial effects:

[0017] In the above scheme, by setting a fixing component, the fixing component can be designed with a snap-on design during use, making the installation of the aeration disc extremely simple. The operator only needs to snap the fixing base onto the fixing sleeve outside the aeration pipe, and then rotate the fixing plate to achieve quick installation of the aeration disc. This can greatly simplify the installation steps and improve work efficiency. At the same time, the design of the arc plate can not only make the fixing plate and the aeration pipe fit more closely, but also reduce the impact of the vibration of the aeration disc on the snap-on joint, thereby ensuring the stability of the connection.

[0018] By setting up a sealing component, during use, the vibration generated by the aeration disc when the air is ejected will be transmitted to the sealing component, and the vibration will cause the air inside the inner cavity in the sealing component to diffuse and flow. Since the inner cavity is connected to a plurality of annular cavities, the diffused air will naturally enter these narrow annular cavities. When the air enters the annular cavity, the wide-mouthed arc groove can enter a large amount of air. Since the space of the annular cavity is relatively small, the flow of air therein will be restricted, thereby generating a certain pressure. This pressure will act on the sealing gasket to squeeze it. Since the material and design of the sealing gasket give it a certain elasticity and deformation ability, it can fit tightly on the surface of the aeration pipe when squeezed, which not only enhances the connection stability between the aeration disc and the aeration pipe, but more importantly, it effectively improves the sealing performance between the two. Due to the close fit of the sealing gasket, it is difficult for the gas to leak out from the gap between the fixed base and the aeration pipe, thereby ensuring the stability and reliability of the aeration effect.

[0035] like Figures 1 to 5 As shown, an embodiment of the utility model provides a biological treatment device for domestic sewage, including an aeration tank body 1, an aeration pipe 2 is fixedly connected to the interior of the aeration tank body 1, a plurality of aeration plates 6 are installed on the outside of the aeration pipe 2, and a fixing component is used to quickly install the aeration plate 6, the fixing component is connected to the aeration plate 6, and a fixing sleeve 8 is fixedly connected to the outside of the aeration pipe 2, and the fixing component includes a fixing base 3 clamped on the outside of the fixing sleeve 8, and both ends of the fixing base 3 are rotatably connected to fixing plates 4, the interiors of the two fixing plates 4 are in conflict with the outside of the aeration pipe 2, and a cavity is opened at the connection of the bottom ends of the two fixing plates 4, a support plate 401 is provided inside the cavity at the bottom end of one of the fixing plates 4, and a guide plate is provided on the side of the support plate 401 facing the other fixing plate 4 402, a limiting column 403 is provided inside the cavity at the bottom end of the other fixed plate 4, a clamping sleeve 404 is provided on the side of the bottom end of one of the fixed plates 4 facing the other fixed plate 4, and a clamping groove adapted to the clamping sleeve 404 is provided at the bottom end of the other fixed plate 4. The fixed plate 4 is in the shape of an arc-shaped wavy plate, and an arc-shaped plate 405 is provided on each arc-shaped raised surface of the fixed plate 4 that contacts the aeration pipe 2. One side of the guide plate 402 is arc-shaped, and the outward side of the limiting column 403 is also arc-shaped. A threaded column 5 is fixedly connected to the top of the fixed base 3, and an air guide cavity 7 is provided inside the threaded column 5. The air guide cavity 7 is fixedly connected to the fixed sleeve 8, and the threaded column 5 is located outside the air guide cavity 7 and an aeration plate 6 is installed through a nut, and an arc cavity is provided between the arc plate 405 and the fixed plate 4.

[0036] During use, the aeration disc 6 is sleeved on the outside of the threaded column 5 so that the aeration disc 6 is located outside the air guide cavity 7, and a nut is screwed on the outside of the threaded column 5. The nut can firmly fix the aeration disc 6 on the outside of the threaded column 5. When fixing, align the groove of the fixed base 3 with the aeration pipe 2 so that the fixed base 3 can fit tightly with the aeration pipe 2. Since both ends of the fixed plate 4 are rotatably connected to the fixed base 3, they can rotate freely around the fixed base 3. As they rotate, the two fixed plates 4 gradually approach each other until their insides form a close contact with the outside of the aeration pipe 2, so that the two fixed plates 4 wrap the aeration pipe 2. During the rotation of the fixed plates 4, the clamping sleeve 404 at the bottom end of one fixed plate 4 gradually approaches the other The clamping groove at the bottom end of the fixed plate 4, as the rotation angle increases, the clamping sleeve 404 will smoothly slide into the clamping groove to form a stable connection. As the clamping sleeve 404 is clamped, the guide plate 402 on the support plate 401 inside the cavity at the bottom end of the fixed plate 4 contacts the limiting column 403. As the support plate 401 moves forward further, the guide plate 402 is deformed by the pressure of the advance and is squeezed with the limiting column 403, and continues to move forward with the limiting column 403 through the arc-shaped surface. When the guide plate 402 completely enters one side of the limiting column 403, the squeezing force disappears, causing the guide plate 402 to rebound, so that one end of the guide plate 402 conflicts with the limiting column 403, thereby further increasing the stability of the clamping.

[0037] At the same time, during the clamping process, the arc plate 405 will first contact the aeration tube 2, and be deformed by being squeezed with the aeration tube 2 and squeezed toward the arc-shaped cavity, so that the arc plate 405 can fit the outer wall of the aeration tube 2 more closely, and can not only be stably fixed on the outside of the aeration tube 2, but also during use, when the aeration disc 6 jets and vibrates, the arc plate 405 can be deformed, so as to buffer the force generated to a certain extent, thereby preventing the vibration from affecting the stability of the clamping.

[0038] In this embodiment, if Figures 1 to 7 As shown, the sealing component is used to improve the sealing effect between the aeration plate 6 and the aeration pipe 2. The sealing component is connected to the fixed component. The sealing component includes an inner cavity 301 opened inside the fixed base 3. A plurality of annular cavities 302 are opened inside the fixed base 3. The annular cavity 302 is connected with the inner cavity 301. A connecting groove is opened on the contact surface between the fixed base 3 and the aeration pipe 2. A sealing gasket 303 is fixedly connected inside the connecting groove. The top of the sealing gasket 303 is in contact with the annular cavity 302. The bottom of the sealing gasket 303 is consistent with the shape of the aeration pipe 2. A wide-mouthed arc groove extending inward is provided on the contact surface between the annular cavity 302 and the inner cavity 301.

[0039] During use, a sealing gasket 303 is glued inside the connecting groove. When the aeration plate 6 is installed and loaded onto the outside of the aeration tube 2, the sealing gasket 303 will fit with the outside of the aeration tube 2. During the use of the aeration plate 6, the aeration plate 6 will spray air to the outside, causing the aeration plate 6 to vibrate violently, causing the fixed base 3 at the connection to vibrate violently. The vibration will drive the air inside the inner cavity 301 to vibrate, and the air inside the inner cavity 301 will diffuse and flow due to the vibration. Since the inner cavity 301 is connected to multiple annular cavities 302, the diffused air will naturally enter these narrow In the annular cavity 302, when air enters the annular cavity 302, since the space of the annular cavity 302 is relatively small, the flow of air therein will be restricted, thereby generating a certain pressure. This pressure will act on the sealing gasket 303 to squeeze it. The sealing gasket 303 can fit tightly on the surface of the aeration pipe 2, which not only enhances the connection stability between the aeration plate 6 and the aeration pipe 2, but also effectively improves the sealing performance between the two. Due to the tight fit of the sealing gasket 303, it is difficult for the gas to leak out from the gap between the aeration plate 6 and the aeration pipe 2, thereby ensuring the stability and reliability of the aeration effect.

[0040] The working process of the utility model is as follows: first, the aeration pipe 2 is laid inside the aeration tank and the aeration pipe 2 is connected to the external aeration equipment, the aeration plate 6 is put on the outside of the threaded column 5 of the fixing component, and it is ensured that the aeration plate 6 is located outside the air guide cavity 7, and the nut is screwed on the outside of the threaded column 5, and the nut firmly fixes the aeration plate 6 on the threaded column 5.

[0041] Next, install the sealing gasket 303 inside the connection groove of the fixed base 3, ensure that the bottom of the sealing gasket 303 is consistent with the shape of the aeration tube 2, align the fixed base 3 of the fixed assembly with the fixed sleeve 8 of the aeration tube 2, ensure that the fixed base 3 and the aeration tube 2 are tightly fitted, and since the fixed plate 4 is rotatably connected to the fixed base 3, the fixed plate 4 can be rotated to gradually approach the aeration tube 2 until the inside of the fixed plate 4 is in close contact with the outside of the aeration tube 2 and wraps the aeration tube 2. During the rotation of the fixed plate 4, a fixed plate The clamping sleeve 404 at the bottom of the 4 will gradually slide into the clamping groove at the bottom of the other fixing plate 4 to form a stable connection. At the same time, the guide plate 402 at the bottom of the fixing plate 4 contacts the limiting column 403. As the guide plate 402 moves forward, it continues to move forward through the arc-shaped surface and the limiting column 403 until the guide plate 402 completely enters one side of the limiting column 403. At this time, the squeezing force disappears and the guide plate 402 rebounds, so that one end of the guide plate 402 contacts the limiting column 403, further increasing the stability of the clamping.

[0042] When the aeration disc 6 is installed and fixed on the outside of the aeration pipe 2, the sealing gasket 303 will fit tightly against the outside of the aeration pipe 2. During the operation of the aeration disc 6, as the aeration disc 6 ejects air, the vibration generated will drive the air inside the fixed base 3 and the inner cavity 301 to vibrate. The vibrating air will enter the annular cavity 302 connected to the inner cavity 301. Since the annular cavity 302 has a small space, the flow of air therein is restricted, and pressure is generated to act on the sealing gasket 303, making it fit tightly against the surface of the aeration pipe 2, thereby enhancing the sealing performance.

[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 preferred embodiment of the present invention, and the present invention can be fully understood by those skilled in the art 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 protection scope of the present invention.
