Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, and more specifically to a liftable disc-type microporous aeration device. Background Art

[0002] In the sewage treatment system, in order to remove pollutants (COD, ammonia nitrogen, total nitrogen, etc.) in the water and achieve the purpose of water purification, single or combined processes such as anaerobic-anoxic-aerobic are often used. In the aerobic process, the system often uses a microporous aerator fixed to the bottom of the pool to supply oxygen to the entire aerobic system; when the microporous aerator or aeration pipeline is damaged or detached, since the microporous aerator is fixed to the bottom of the pool by expansion bolts, it is necessary to stop the water inlet of the sewage treatment system when replacing it, and empty the sewage and sludge in the aerobic pool body before replacing and repairing the microporous aerator, which is very inconvenient to operate.

[0003] The most commonly used mainstream aeration device in society is the disc microporous aerator, which is mainly fixed to the bottom of the pool by expansion bolts and cannot be moved or lifted. When repairing and replacing, it is necessary to stop the water supply to the system and drain the sewage and sludge in the system. The existing liftable aerator mainly adopts the tubular aerator, which is fixed by a vertical aeration steel pipe. Each group of tubular aerators is fixed at one point, and the fixed point is located at the center of each group of tubular aerators. The two ends of the pipe are not fixed. Its main disadvantages include: (1) The fixed disc microporous aerator at the bottom of the pool cannot be replaced or repaired without stopping the water; (2) There are no fixed points at both ends of the lifting tube aerator pipe, which will shake back and forth, resulting in unstable oxygen supply in the system; (3) The oxygen supply efficiency of the liftable tube aerator is slightly lower than that of the microporous aerator, and the pressure head loss is higher than that of the microporous aerator; (4) The liftable tube aerator has a large number of groups arranged in the same area, and each group corresponds to an air supply branch pipe, with more branch pipes and joints.

[0004] Therefore, it is an urgent problem to be solved by those skilled in the art to provide a liftable disc-type microporous aeration device with a stable structure, a long service life and easy maintenance. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, the utility model aims to provide a liftable disc-type microporous aeration device which can realize replacement of the aeration system without stopping the water supply and emptying the pool body.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions, which mainly include:

[0007] A liftable disc-type microporous aeration device comprises an aeration tank body, a hoisting part, an aeration frame, a first bracket, a fixed clamp, a microporous aerator and an aeration pipe. The aeration frame is installed at the bottom of the aeration tank body, the aeration pipe is installed on the aeration frame, a plurality of microporous aerators are installed on the aeration pipe, the aeration pipe is welded to the aeration frame by a fixed clamp, the aeration frame is vertically installed with a hoisting part, and a first bracket is provided between the aeration frame and the side wall of the aeration tank body.

[0008] Preferably, the hoisting part includes a hoisting bracket, a winch, a lifting bracket, a third bracket and a first diagonal brace. The hoisting bracket is installed in the vertical direction of the aeration base frame, the hoisting bracket is connected to the aeration base frame through the first diagonal brace bolts, the upper part of the hoisting bracket is connected to the water tank body through the third bracket, a hoisting hole is provided on the top of the hoisting bracket, a lifting bracket is installed on the top of the aeration tank body, and a winch is provided on the lifting bracket.

[0009] Preferably, a plurality of frame support frames are provided between the aeration frame and the bottom of the aeration tank body to improve the stability of the aeration frame.

[0010] Preferably, a second diagonal brace and a transverse brace are provided inside the hanging bracket to improve the stability of the hanging bracket.

[0011] Preferably, the first bracket is a "trapezoidal" bracket, with the hypotenuse facing the aeration base frame during installation.

[0012] Preferably, the aeration chassis is made of stainless steel.

[0013] It can be seen from the above technical solution that compared with the prior art:

[0014] 1. The world's mainstream disc microporous aerator is used as the main component of the liftable aerator, and the disc microporous aerator is fixed on the stainless steel aeration frame, which realizes the liftable maintenance and replacement of the disc microporous aerator. At the same time, because the stainless steel aeration frame has a large number of fixed points and a stable structure, the disc microporous aerator is evenly distributed, which can ensure the stability of the pool aeration;

[0015] 2. As an aeration product with a longer service life, a higher market share, and greater market acceptance and recognition, the disc-type microporous aerator has high oxygen supply efficiency, small pressure head loss, higher cost performance, and is more accepted and recognized by users;

[0016] 3. The stainless steel aeration frame is customized according to the pool body and pool type. A single lifting aeration frame has a wider service range and fewer quantities, and the corresponding supporting aeration branch pipes and valves are fewer;

[0017] 4. The stainless steel aeration frame is fixed with a trapezoidal bottom bracket to prevent it from moving forward, backward, left and right when the pool is aerated normally. During installation, the disc-type microporous aerator can be lifted and slid to the bottom of the pool through the hypotenuse of the triangular bottom bracket, which is convenient for installation and fixation.

[0018] 5. The stainless steel aeration frame and the hoisting part are assembled with bolts. The top of the hoisting part is fixedly connected to the water pool through a water pool fixing bracket, which limits the forward, backward, left and right movement of the top of the entire liftable disc microporous aerator, ensuring the stability of the entire liftable disc microporous aerator;

[0019] 6. A mobile lifting bracket is set on the top of the pool, and a winch is installed on the mobile lifting bracket, and a hook is set. The disc microporous aerator can be lifted without stopping the water and draining the sewage sludge in the pool, which facilitates the replacement and maintenance of the microporous aeration system and ensures the long-term and effective operation of the entire sewage system.

The aeration frame 7 is installed at the bottom of the aeration tank body 1, and the aeration pipe 14 is installed on the aeration frame 7. A plurality of microporous aerators 13 are installed on the aeration pipe 14. The aeration pipe 14 is welded to the aeration frame 7 by a fixed clamp 5. The aeration frame 7 is vertically installed with a hanging part, and a first bracket 4 is provided between the aeration frame 7 and the side wall of the aeration tank body 1.

[0029] In order to further optimize the above scheme, the hoisting part includes a hoisting bracket 2, a winch 8, a lifting bracket 9, a third bracket 12 and a first diagonal brace 3. The hoisting bracket 2 is installed in the vertical direction of the aeration base frame 7. The hoisting bracket 2 is bolted to the aeration base frame 7 through the first diagonal brace 3. The upper part of the hoisting bracket 2 is connected to the water tank body through the third bracket 12. A hoisting hole is provided on the top of the hoisting bracket 2. A lifting bracket 9 is installed on the top of the aeration tank body 1, and a winch 8 is provided on the lifting bracket 9.

[0030] In order to further optimize the above solution, a plurality of base frame support frames 6 are provided between the aeration base frame 7 and the bottom of the aeration tank body 1 to improve the stability of the aeration base frame 7 .

[0031] In order to further optimize the above solution, a second diagonal brace 10 and a transverse brace 11 are provided inside the hanging bracket 2 to improve the stability of the hanging bracket 2 .

[0032] In order to further optimize the above solution, the first bracket 4 is a "trapezoidal" bracket, and the oblique edge faces the aeration base frame 7 during installation.

[0033] In order to further optimize the above solution, the aeration frame 7 is made of stainless steel.

[0034] Working principle: The aeration frame 7 of the present application is designed according to the aeration gas volume and the size of the aeration tank body 1. The disc-type microporous aerator 13 is arranged on the aeration frame 7 according to the design. The microporous aerator 13 is fixed on the aeration pipe 14 and connected in a ring shape. The aeration pipe 14 is fixed by the aeration pipe 14 fixing clamp 5 and welded to the aeration frame 7. The aeration frame 7 is supported by the frame support frame 6 at the bottom of the pool; the aeration frame 7 is vertically installed with a hoisting bracket 2, and the hoisting bracket 2 is bolted to the aeration frame 7 by the first diagonal brace 3. The hoisting bracket 2 is provided with a second diagonal brace 10 and a horizontal brace 11 to ensure the stability of the entire hoisting part; the upper part of the hoisting bracket 2 is connected to the aeration tank body 1 through the third bracket 12 to ensure the stability of the upper part of the entire lifting bracket 9 in front, back, left, right, up and down directions. The upper part of the hoisting bracket 2 is provided with a hoisting hole, which is connected to the hook of the winch 8 on the lifting bracket 9. The hoisting disc microporous aerator 13 is lifted to the pool surface by the winch 8, and the lifting of the microporous aerator 13 is achieved by lifting the entire aeration frame 7, so that the aeration device can be lifted, inspected and replaced without stopping water and discharging mud, thereby ensuring the long-term effective operation of the entire sewage treatment system. During the installation and sliding of the aeration frame 7, the trapezoidal first bracket 4 slides down through the oblique edge, and the first bracket 4 can ensure the stability of the bottom of the liftable disc microporous aerator 13 during aeration.

[0035] This patent abandons the tubular aerator as the main component of the liftable aerator, and adopts the disc-type microporous aerator 13, which has a longer service life, is more mainstream, and is used in more scenarios, as the main component of the liftable aerator. The disc-type microporous aerator 13 originally fixed on the bottom of the pool is directly fixed on the aeration frame 7, and the aerator is lifted by lifting the entire aeration frame 7. Because different aeration components are used and all are directly fixed on the liftable bracket 9, the shortcomings of the tubular aerator having no fixed end and unstable aeration are directly overcome.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
