Description

Technical Field

[0001] This utility model relates to the field of microporous aerator technology, and in particular to a microporous aerator that can be quickly disassembled and assembled. Background Technology

[0002] Microporous aerators are core components of wastewater treatment aeration systems. Among them, disc aerators are widely used due to their advantages such as large aeration area and uniform bubble distribution. The connection between disc aerators and aeration pipes generally relies on special connecting fittings. First, the connecting fittings are fixed to the preset interface of the aeration pipe with bolts. Then, the mounting sleeve at the bottom of the disc aerator is connected to the mounting seat on the connecting fitting by screwing them together. In daily operation and maintenance, when it is necessary to disassemble and repair the aerator and connecting fittings, the threaded connection between the disc aerator and the connecting fitting must be unlocked first, and then the fixing bolts between the connecting fitting and the pipe must be removed separately. The two steps must be performed separately. Especially in scenarios where there are many aerators in the wastewater treatment tank, the repeated step-by-step disassembly operation will significantly extend the maintenance time and increase the operation and maintenance costs. The rotation angle of the threaded connection cannot be uniform during installation. If the rotation is too loose, there will be a gap between the mounting sleeve and the mounting seat, which will cause gas leakage during aeration and reduce aeration efficiency. If the rotation is too tight, it is easy to damage the threads of the mounting sleeve or the mounting seat, which will not only affect subsequent disassembly and assembly, but may also further damage the aeration stability due to seal failure. Utility Model Content

[0003] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0004] In view of the problems existing in the above and / or existing quick-disassembly microporous aerators, this utility model is proposed.

[0005] Therefore, the problem that this utility model aims to solve is that when the disc aerator is connected to the pipeline through connecting accessories, maintenance requires separate unlocking and disassembly in stages, resulting in low efficiency. Furthermore, the rotation angle of the threaded connection is difficult to control and is prone to affecting the aeration effect due to being too loose or too tight.

[0006] To solve the above technical problems, this utility model provides the following technical solution: a microporous aerator that can be quickly disassembled and assembled, comprising a main body component, an aerator, and a fixing sleeve fixed at the bottom of the aerator; The mounting assembly includes a connector located at the bottom of the fixing sleeve. The connector includes a first arc-shaped plate, a second arc-shaped plate hinged to the first arc-shaped plate, and a mounting sleeve fixed on the first arc-shaped plate. The fixing sleeve is sleeved over the mounting sleeve, and a sealing ring is provided on the mounting sleeve. The mounting assembly also includes a mounting component located on the fixing sleeve. The mounting component includes a fixing post fixed to the mounting sleeve. The fixing sleeve has a straight groove and an inclined groove. A locking block is slidably disposed inside the fixing sleeve, and a spring is fixed on one side of the locking block.

[0007] As a preferred embodiment of the microporous aerator that can be quickly disassembled and assembled according to this utility model, a rubber pad is fixed on the first arc plate and the second arc plate, and a magnet is fixed inside the rubber pad.

[0008] As a preferred embodiment of the microporous aerator that can be quickly disassembled and assembled according to the present invention, one end of the locking block is inclined and the one end of the locking block can be located in the inclined groove.

[0009] As a preferred embodiment of the microporous aerator that can be quickly disassembled and assembled according to this utility model, wherein: a pull plate is fixed on the locking block, and one end of the pull plate is located outside the fixing sleeve.

[0010] As a preferred embodiment of the quick-disassembly microporous aerator of this utility model, the installation assembly further includes a locking component located on the first arc-shaped plate. The locking component includes an auxiliary block fixed to the first arc-shaped plate. A sliding groove is provided on the auxiliary block, and a sliding plate is slidably disposed in the sliding groove. An upper locking block is fixed on the sliding plate. A fixing plate is fixed on the second arc-shaped plate, and a lower locking block is fixed on the fixing plate.

[0011] As a preferred embodiment of the microporous aerator that can be quickly disassembled and assembled according to this utility model, a rotating plate is fixed on the fixed sleeve, and a movable column is fixed at the bottom of the rotating plate.

[0012] As a preferred embodiment of the microporous aerator that can be quickly disassembled and assembled according to this utility model, a U-shaped frame is fixed on the sliding plate, and the movable column can be located inside the U-shaped frame.

[0013] As a preferred embodiment of the quick-disassembly microporous aerator of this utility model, the sliding plate has a T-shaped cross-section, and the shape of the sliding groove corresponds to it.

[0014] As a preferred embodiment of the quick-disassembly microporous aerator described in this utility model, the upper locking block is provided with a first inclined surface.

[0015] As a preferred embodiment of the microporous aerator that can be quickly disassembled and assembled according to this utility model, there are multiple upper and lower locking blocks, and they correspond one-to-one.

[0016] The beneficial effects of this utility model are as follows: by setting the installation components, the connecting accessories are first pre-fixed to the preset interface of the aeration pipe. The aerator adopts the installation method of pressing and rotating at the same time. When the aerator approaches the connecting accessories and rotates to the designated position, it automatically triggers the locking to achieve a stable connection between the two. When maintaining and disassembling, it is only necessary to unlock the lock between the aerator and the connecting accessories, which will simultaneously trigger the unlocking between the connecting accessories and the pipe. There is no need for separate operation in each step, which shortens the maintenance time. Attached Figure Description

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0028] Example 1 Reference Figures 1-5 This is the first embodiment of the present invention. This embodiment provides a microporous aerator that can be quickly disassembled and assembled. The microporous aerator that can be quickly disassembled and assembled includes a main body component 1, an aerator 11, and a fixing sleeve 12 fixed to the bottom of the aerator 11. The aerator 11 is used in a sewage treatment aeration system and is disc-shaped. It converts compressed air into tiny bubbles through a microporous structure to oxygenate the water. This is prior art, and this solution will not be described in detail. Moreover, those skilled in the art can clearly understand the working principle.

[0029] Mounting assembly 2 includes a connector 21 located at the bottom of the fixed sleeve 12, the connector 21 being used to provide a mounting base for the aerator 11 on the pipe 3.

[0030] The connector 21 includes a first arc-shaped plate 211, a second arc-shaped plate 212 hinged to the first arc-shaped plate 211, an mounting sleeve 213 fixed on the first arc-shaped plate 211, a fixing sleeve 12 sleeved on the mounting sleeve 213, a sealing ring 214 provided on the mounting sleeve 213, and an installation groove corresponding to the mounting sleeve 213 opened in the fixing sleeve 12. The sealing ring 214 is used to seal the mounting sleeve 213 and the fixing sleeve 12. The sealing ring 214 is replaceable.

[0031] During installation, the first arc plate 211 and the second arc plate 212 need to be fitted onto the pipe 3 first, and the two need to be pre-fixed.

[0032] The mounting assembly 2 also includes a mounting piece 22 located on the fixed sleeve 12, which is used to mount the aerator 11 onto the connector 21.

[0033] Mounting component 22 includes a fixing post 221 fixed to mounting sleeve 213. The fixing sleeve 12 has a straight groove 12-1 and an inclined groove 12-2, which are connected to each other. The straight groove 12-1 is connected to the bottom end face of the fixing sleeve 12. A locking block 222 is slidably disposed inside the fixing sleeve 12. A spring 223 is fixed on one side of the locking block 222, and the other end of the spring 223 is fixed inside the fixing sleeve 12. The spring 223 provides a continuous thrust to the locking block 222.

[0034] When installing the aerator 11, the positions of the aerator 11 and the fixing sleeve 12 need to be adjusted so that the straight groove 12-1 and the fixing column 221 are coaxial. Then, the aerator 11 is placed downwards, and the fixing column 221 will slide into the straight groove 12-1. After that, the fixing column 221 will move into the inclined groove 12-2, thereby driving the aerator 11 to rotate at a certain angle. The aerator 11 moves downwards and rotates until the inner wall of the mounting groove in the fixing sleeve 12 is tightly fitted with the sealing ring 214 on the mounting sleeve 213, thereby ensuring the sealing between the fixing sleeve 12 and the mounting sleeve 213. At the same time, after rotating to the designated position, the locking block 222 will cooperate with the inner wall of the inclined groove 12-2 to restrict the movement of the fixing column 221, thereby locking the position of the fixing sleeve 12 and ensuring the reliability of the aerator 11 installation.

[0035] Example 2 Reference Figures 3-8 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0036] Specifically, rubber pads 215 are fixed on the first arc plate 211 and the second arc plate 212, and magnets are fixed inside the rubber pads 215. The first arc plate 211 and the second arc plate 212 are hinged together, and then they are fitted onto the pipe 3. Pushing the second arc plate 212 to rotate, the magnet has a large magnetic force. Under the action of the magnet, the first arc plate 211 and the second arc plate 212 will form a complete ring. Fitted onto the pipe 3, they will not separate without other large external forces, and their positions on the pipe 3 will not change, thus forming a pre-fixed structure.

[0037] Specifically, one end of the locking block 222 is inclined, and the other end of the locking block 222 can be located inside the inclined slot 12-2. By setting it in an inclined shape, when the fixing column 221 enters the straight slot 12-1 and then slides into the inclined slot 12-2 during installation, the fixing column 221 will first contact the inclined surface of the locking block 222 and apply a pushing force to the locking block 222, causing the spring 223 to compress. At this time, the locking block 222 will not hinder the movement of the fixing column 221. When the fixing column 221 slides to fit against the arc surface of the inclined slot 12-2, the fixing column 221 will not apply pressure to the locking block 222. The spring 223 will cause a part of the locking block 222 to be located inside the inclined slot 12-2 again. At this time, the locking block 222, together with the inner wall of the inclined slot 12-2, will restrict the movement of the fixing column 221, and the position of the fixing column 221 will be locked, thereby locking the position of the fixing sleeve 12 relative to the mounting sleeve 213, and thus completing the installation of the aerator 11.

[0038] Specifically, a pull plate 224 is fixed on the locking block 222. One end of the pull plate 224 is located outside the fixing sleeve 12. The pull plate 224 is used to release the limit of the fixing column 221. When it is necessary to disassemble the aerator 11, push the pull plate 224 to move the locking block 222 away from the inclined slot 12-2. The spring 223 is compressed, so that the fixing column 221 can move freely between the inclined slot 12-2 and the straight slot 12-1. Finally, it moves out of the straight slot 12-1, thus completing the separation of the aerator 11 from the connector 21.

[0039] Specifically, the installation component 2 also includes a locking member 23 located on the first arc plate 211. The locking member 23 is configured to simultaneously trigger the position locking of the first arc plate 211 and the second arc plate 212 when locking the aerator 11, ensuring that the connector 21 and the pipe 3 are stably fixed.

[0040] The locking component 23 includes an auxiliary block 231 fixed on the first arc-shaped plate 211. A sliding groove 231-1 is provided on the auxiliary block 231. A sliding plate 232 is slidably disposed in the sliding groove 231-1. The length of the sliding plate 232 is less than that of the sliding groove 231-1. An upper locking block 233 is fixed on the sliding plate 232. A fixing plate 234 is fixed on the second arc-shaped plate 212. A lower locking block 235 is fixed on the fixing plate 234. The upper locking block 233 and the lower locking block 235 have an L-shaped cross section.

[0041] When combining the first arc plate 211 and the second arc plate 212 into a complete arc, it is necessary to adjust the sliding plate 232 to contact one end of the slide groove 231-1. At this time, the positions of the upper locking block 233 and the lower locking block 235 are staggered, which will not hinder the fit of the first arc plate 211 and the second arc plate 212. Then, the upper locking block 233 is moved so that it engages with the lower locking block 235, thereby locking the position of the sliding plate 232 and the fixed plate 234, and thus locking the relative position of the first arc plate 211 and the second arc plate 212, ensuring that the connector 21 and the pipe 3 are stably fixed.

[0042] Example 3 Reference Figures 2-8 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0043] Specifically, a rotating plate 236 is fixed on the fixed sleeve 12, and a movable column 237 is fixed at the bottom of the rotating plate 236. When the fixed sleeve 12 rotates, it will drive the rotating plate 236 and the movable column 237 to rotate synchronously.

[0044] Specifically, a U-shaped frame 238 is fixed on the sliding plate 232, and the moving column 237 can be located inside the U-shaped frame 238. In the initial state, the sliding plate 232 is in contact with one end of the slide groove 231-1. At this time, the angle of the fixed sleeve 12 is adjusted so that the fixed column 221 is coaxial with the straight groove 12-1. At this time, the moving column 237 and the U-shaped frame 238 are also in a coaxial position. The fixed sleeve 12 is moved downward so that the moving column 237 moves downward synchronously and enters the U-shaped frame 238. After that, the rotation of the fixed sleeve 12 will also drive the rotating plate 236 and the moving column 237 to rotate synchronously. A part of the moving column 237 is always located inside the U-shaped frame 238, which in turn drives the U-shaped frame 238 to translate. At this time, the sliding plate 232 will slide in the slide groove 231-1, which drives the upper locking block 233 to translate and engage with the lower locking block 235.

[0045] Once the position of the fixed column 221 is locked, the position of the fixed sleeve 12 is also locked, thereby fixing the position of the movable column 237 and the position of the U-shaped frame 238, which in turn fixes the positions of the sliding plate 232 and the upper locking block 233. At this time, the engagement of the upper locking block 233 and the lower locking block 235 will be locked, thereby ensuring the stability of the connector 21 installation.

[0046] Specifically, the sliding plate 232 has a T-shaped cross-section, and the shape of the sliding groove 231-1 corresponds to it. The T-shape allows the sliding plate 232 to slide smoothly within the sliding groove 231-1, but the two will not separate.

[0047] Specifically, the upper locking block 233 is provided with a first inclined surface 233-1, and the lower locking block 235 is provided with an inclined surface corresponding to the first inclined surface 233-1. When the upper locking block 233 moves horizontally and gradually engages with the lower locking block 235, the first inclined surface 233-1 will contact the inclined surface of the lower locking block 235 and apply an upward pushing force to the inclined surface of the lower locking block 235, thereby causing the lower locking block 235 to have an upward movement tendency. The rubber pad 215 will be compressed, so that the connection between the first arc plate 211 and the second arc plate 212 can be tighter. At the same time, the first arc plate 211 and the second arc plate 212 also have tighter contact with the outer wall of the pipe 3, increasing the friction between the two and the pipe 3, thereby ensuring the stability of the connector 21 installed on the pipe 3.

[0048] Specifically, there are multiple upper locking blocks 233 and lower locking blocks 235, and they correspond one-to-one. Through the joint cooperation of multiple sets of upper locking blocks 233 and lower locking blocks 235, the relative positions of the first arc plate 211 and the second arc plate 212 are locked.

[0049] In use, first install the connector 21 on the pipe 3, then put the first arc plate 211 and the second arc plate 212 on the pipe 3, push the second arc plate 212 to rotate, the magnet has a large magnetic force, under the action of the magnet, the first arc plate 211 and the second arc plate 212 will form a complete ring, and be put on the pipe 3 to form a pre-fixed shape.

[0050] Next, by holding the first arc plate 211, adjust the position of the aerator 11 and the fixing sleeve 12 so that the straight groove 12-1 and the fixing column 221 are coaxial. Then, place the aerator 11 downwards. The fixing column 221 will slide into the straight groove 12-1. Then, the fixing column 221 will move into the inclined groove 12-2. The inner wall of the mounting groove in the fixing sleeve 12 is tightly fitted with the sealing ring 214 on the mounting sleeve 213, thereby ensuring the sealing between the fixing sleeve 12 and the mounting sleeve 213. The locking block 222, in conjunction with the inner wall of the inclined groove 12-2, will restrict the movement of the fixing column 221. The position of the fixing column 221 is locked, thereby locking the position of the fixing sleeve 12 relative to the mounting sleeve 213, thus completing the installation of the aerator 11.

[0051] When the fixed sleeve 12 is moved downward, the moving column 237 moves downward synchronously and enters the U-shaped frame 238. Then, the rotation of the fixed sleeve 12 will also drive the rotating plate 236 and the moving column 237 to rotate synchronously. A part of the moving column 237 is always located inside the U-shaped frame 238, which in turn drives the U-shaped frame 238 to translate. At this time, the sliding plate 232 will slide in the slide groove 231-1, which drives the upper locking block 233 to translate and engage with the lower locking block 235, thereby ensuring the stability of the connector 21 installation.

[0052] When disassembly is required, push the pull plate 224 to move the locking block 222 away from the inclined slot 12-2. The spring 223 is compressed, allowing the fixed column 221 to move freely between the inclined slot 12-2 and the straight slot 12-1. Finally, it moves out of the straight slot 12-1, thus completing the separation of the aerator 11 from the connector 21. At the same time, the upper locking block 233 will move in the opposite direction and separate from the lower locking block 235, thereby releasing the locking of the first arc plate 211 and the second arc plate 212. Then, use a larger external force to overcome the magnetic force and separate the two, so that the connector 21 can be removed from the pipe 3, thereby improving the time required for maintenance disassembly.

[0053] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
