Description

Technical Field

[0001] This utility model relates to the field of aeration tank technology, specifically to a connection structure for the air inlet pipe of a sewage treatment aeration tank. Background Technology

[0002] With increasingly stringent environmental standards, the requirements for wastewater treatment efficiency and quality are constantly rising. Efficient aeration is one of the key factors in ensuring wastewater treatment effectiveness. This requires the air inlet pipe connection structure to ensure stable and uniform air intake, providing sufficient oxygen for the growth and metabolism of microorganisms in the aeration tank. While the existing air inlet pipe connection structures for wastewater treatment aeration tanks can basically meet daily usage needs, there are still some shortcomings that need improvement.

[0003] Because the wastewater in the aeration tank contains a large amount of suspended solids, microorganisms, and various chemical substances, the air inlet is easily blocked by suspended solids, microbial films, or chemical precipitates in the wastewater during long-term use, affecting the uniformity of airflow distribution. It is necessary to manually disassemble the air inlet and then unclog it. However, since the aeration tank is usually large in volume and located underground or semi-underground with relatively narrow space, it is difficult to disassemble the air inlet. Therefore, we propose an air inlet pipe connection structure for wastewater treatment aeration tanks to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a connection structure for the air inlet pipe of a sewage treatment aeration tank, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a connection structure for an air inlet pipe of a sewage treatment aeration tank, comprising an aeration tank and an aeration disc installed at the bottom of the aeration tank, an air inlet main pipe provided on the left side of the aeration tank, an air inlet main pipe installed at the upper left side of the aeration disc, a connecting cylinder provided at the top of the air inlet main pipe, the connecting cylinder being connected to an air distribution box, a sieve plate placed inside the connecting cylinder, two sets of handles installed at the top of the sieve plate, a cover plate provided at the top of the connecting cylinder, and a locking component installed on the left side of the top of the aeration tank and connected to the cover plate.

[0006] As a further preferred embodiment of this technical solution, the locking assembly includes a sleeve, a movable disc, a column, a connecting plate, a return spring, a screw hole, a threaded groove, and a screw rod. A sleeve is installed on the left side of the top of the aeration disc, and a movable disc is disposed inside the sleeve. A column is fixed at the center of the top of the movable disc. The outer wall of the column is connected to the outer wall of the cover plate through the connecting plate. A return spring is wound around the outside of the column. A screw hole is opened at the center of the movable disc and the column. A threaded groove is opened in the middle of the inside of the sleeve. A screw rod is threadedly connected to the screw hole and the threaded groove.

[0007] As a further preferred embodiment of this technical solution, a sealing strip is adhesively bonded to the inner wall of the cover plate.

[0008] As a further preferred embodiment of this technical solution, the two ends of the reset spring are respectively connected to the top outer wall of the movable disk and the top of the inner wall of the sleeve, and the movable disk is elastically connected to the inner wall of the sleeve through the reset spring.

[0009] As a further preferred embodiment of this technical solution, the outer diameter of the movable disk is the same as the inner diameter of the sleeve, and the movable disk and the sleeve are slidably connected.

[0010] As a further preferred embodiment of this technical solution, multiple sets of anti-slip grooves are equally spaced on the outer wall of the top of the screw.

[0011] This utility model provides a connection structure for the air inlet pipe of a wastewater treatment aeration tank, which has the following beneficial effects:

[0012] 1. This utility model features a connecting cylinder between the main air intake pipe and the air distribution box, allowing the main air intake pipe to connect to the main air intake pipe via the connecting cylinder. A detachable screen plate is installed inside the connecting cylinder, enabling the screen plate to filter suspended solids in wastewater, effectively preventing blockage of the air intake pipe. Furthermore, a detachable cover plate is installed at the top of the connecting cylinder, allowing for quick sealing of the top of the connecting cylinder. This facilitates the rapid removal of the screen plate inside the connecting cylinder to clean any residual suspended solids, effectively reducing disassembly difficulty and improving the ease of use of the device.

[0013] 2. This utility model has a sleeve installed at the top of the aeration disc, and a movable disc that can be raised, lowered, and rotated is set inside the sleeve. When it is necessary to close the top of the connecting cylinder, the cover plate is first moved to the top of the connecting cylinder, and then the upward tension on the screw is released, allowing the return spring outside the column to release its elasticity and push the movable disc downward, so that the cover plate can quickly move to the outside of the upper end of the connecting cylinder for initial sealing. Then, the screw is rotated in the opposite direction, so that the bottom end of the screw rotates into the threaded groove inside the sleeve, thus fixing the cover plate at the top of the connecting cylinder, thereby improving the stability of the device during use.

[0022] Meanwhile, the meaning of "and / or" or "and / or" appearing throughout the text is that it includes three options. Taking "A and / or B" as an example, it includes option A, option B, or an option that satisfies both A and B.

[0023] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0024] This utility model provides a technical solution as follows: Figures 1 to 5As shown in this embodiment, an air inlet pipe connection structure for a wastewater treatment aeration tank includes an aeration tank 1 and an aeration disc 2 installed at the bottom of the aeration tank 1. An air inlet main pipe 3 is provided on the left side of the aeration tank 1. An air inlet main pipe 3 is installed at the upper left side of the aeration disc 2. A connecting cylinder 5 is provided at the top of the air inlet main pipe 3. The connecting cylinder 5 is connected to the air distribution box 4. A screen plate 6 is placed inside the connecting cylinder 5. Two sets of handles 7 are installed at the top of the screen plate 6. A cover plate 8 is provided at the top of the connecting cylinder 5. A locking component is installed on the left side of the top of the aeration tank 1 and connected to the cover plate 8.

[0025] By providing a connecting cylinder 5 between the main air intake pipe 3 and the air distribution box 4, the main air intake pipe 3 can be connected to the main air intake pipe 4 through the connecting cylinder 5. A detachable screen plate 6 is installed inside the connecting cylinder 5, which can filter suspended solids in the sewage, thereby effectively preventing blockage of the air intake pipe. Furthermore, a detachable cover plate 8 is installed at the top of the connecting cylinder 5, which can be quickly formed or unsealed to close the top of the connecting cylinder 5. This facilitates the quick extraction of the screen plate 6 inside the connecting cylinder 5 to clean the suspended solids remaining inside the screen plate 6, thus improving the convenience of using the device.

[0026] In other embodiments, the locking assembly includes a sleeve 9, a movable disc 10, a column 11, a connecting plate 12, a return spring 13, a screw hole 14, a threaded groove 15, and a screw 16. The sleeve 9 is installed on the left side of the top of the aeration disc 2. The movable disc 10 is disposed inside the sleeve 9. The column 11 is fixed at the center of the top of the movable disc 10. The outer wall of the column 11 is connected to the outer wall of the cover plate 8 through the connecting plate 12. The return spring 13 is wound around the outside of the column 11. The screw hole 14 is opened at the center of the movable disc 10 and the column 11. The threaded groove 15 is opened in the middle of the inside of the sleeve 9. The screw 16 is threadedly connected to the screw hole 14 and the threaded groove 15.

[0027] A sleeve 9 is installed at the top of the aeration disc 2, and a movable disc 10 that can be raised, lowered, and rotated is installed inside the sleeve 9. When it is necessary to open the top of the connecting cylinder 5, the screw 16 can be rotated so that the bottom end of the screw 16 leaves the threaded groove 15 at the bottom end of the sleeve 9, thus releasing the fixed connection between the movable disc 10 and the sleeve 9. Then, the screw 16 is pulled upward so that the column 11 can drive the cover plate 8 to move upward, and the movable disc 10 is pressed against the return spring 13 outside the column 11 under the action of the column 11. When the cover plate 8 is completely removed from the outside of the connecting cylinder 5, the cover plate 8 can be moved so that the cover plate 8 drives the movable disc 10 along the axis of the sleeve 9. Rotate the cover plate 8 to move it away from the upper end of the connecting cylinder 5, which can quickly open the top of the connecting cylinder 5. When it is necessary to close the top of the connecting cylinder 5, repeat the above operation in reverse. First, move the cover plate 8 directly above the connecting cylinder 5, then release the upward pull on the screw 16, allowing the return spring 13 outside the column 11 to release its elasticity and push the movable plate 10 downward, so that the cover plate 8 can quickly move to the outside of the upper end of the connecting cylinder 5 for initial sealing. Then, rotate the screw 16 in reverse so that the bottom end of the screw 16 rotates into the threaded groove 15 inside the sleeve 9, which can fix the cover plate 8 to the top of the connecting cylinder 5, thereby improving the stability of the device during use.

[0028] In other embodiments, a sealing strip is adhesively bonded to the inner wall of the cover plate 8;

[0029] This design effectively improves the sealing effect of the cover plate 8 on the top of the connecting cylinder 5 when the cover plate 8 moves to the top of the connecting cylinder 5, ensuring the stability of the equipment during use.

[0030] In other embodiments, the two ends of the return spring 13 are respectively connected to the outer wall of the top of the movable disk 10 and the top of the inner wall of the sleeve 9, and the movable disk 10 is elastically connected to the inner wall of the sleeve 9 through the return spring 13;

[0031] This design allows the return spring 13 to continuously apply a downward elastic force to the movable disc 10, enabling the movable disc 10 to drive the cover plate 8 to move quickly downward to the outside of the connecting cylinder 5, thus initially positioning the connecting cylinder 5.

[0032] In other embodiments, the outer diameter of the movable disk 10 is the same as the inner diameter of the sleeve 9, and the movable disk 10 and the sleeve 9 are slidably connected.

[0033] This design effectively prevents the movable disc 10 from shaking during movement when it moves up and down or rotates within the sleeve 9, thus improving the ease of use of the device.

[0034] In other embodiments, multiple sets of anti-slip grooves are equally spaced on the outer wall of the top end of the screw 16;

[0035] This design effectively increases the friction between the tip of the screw 16 and the hand when the hand pulls or rotates the screw 16, making it easier to use the screw 16 with less effort.

[0036] The electrical components mentioned in this article are all electrically connected to an external main controller and industrial power supply, and the main controller can be a conventional known device such as a computer that provides control.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
