Description

Technical Field

[0001] This utility model belongs to the field of sewage treatment equipment, and more specifically relates to a device for replacing aerator membranes. Background Technology

[0002] Aeration is a key process in the aerobic stage of biological wastewater treatment. Aeration provides sufficient dissolved oxygen to the wastewater, while continuous mixing is achieved by auxiliary stirring equipment. This ensures that the organic matter in the wastewater comes into full contact with microorganisms and dissolved oxygen, guaranteeing that the microorganisms can oxidize and decompose the organic matter under sufficient dissolved oxygen conditions.

[0003] Traditional disc aerators may become clogged or malfunction after a period of use, requiring complete replacement, which is not only time-consuming and labor-intensive, but also results in high maintenance costs. Utility Model Content

The quick-release device includes a horizontally arranged operating rod and a connecting rod arranged perpendicular to the middle of the operating rod. A plurality of first mounting plates are spaced apart at the end of the connecting rod away from the operating rod. The lower end face of each of the first mounting plates is provided with a positioning pin, which can be inserted into the positioning hole of the aerator.

[0007] In a specific embodiment of this utility model, the mounting frame includes at least two sets of spaced-apart fixing members and a plurality of support rods arranged perpendicular to the fixing members.

[0028] The following disclosure provides many different implementation methods or examples for different solutions to implement this utility model.

[0029] See attached document Figure 1 To be continued Figure 5 As shown, an apparatus for replacing aerator diaphragms is applicable to diaphragm aerators. It includes a mounting bracket 1 for installing the aerator and a quick-release device 3. The quick-release device 3 includes a horizontally arranged operating rod 31 and a connecting rod 32 arranged perpendicular to the middle of the operating rod 31.

[0030] In one embodiment of this utility model, four first mounting plates 33 are provided at intervals at the end of the connecting rod 32 away from the operating rod 31, and positioning pins 331 that can be inserted into the positioning holes of the aerator are respectively provided on the lower end face of the first mounting plates 33.

[0031] In one embodiment of this utility model, the mounting frame 1 includes two sets of spaced-apart fixing members and a plurality of support rods 11 arranged perpendicular to the fixing members, and a reinforcing rod 5 is provided between adjacent support rods 11 to improve the overall stability of the mounting frame 1.

[0032] In one embodiment of this utility model, each set of fixing members includes two correspondingly arranged second mounting plates 12. A gap 4 is provided between the two second mounting plates 12 for aerator installation. By providing arc surfaces 121 on the inner sides of both ends of the second mounting plates 12 to facilitate aerator installation, a number of aerators can be installed sequentially within the gap 4 through the arc surfaces 121.

[0033] In one embodiment of this utility model, the aerator includes a bottom shell and an upper shell. Four positioning holes are evenly spaced on the upper shell. The process of making the positioning holes is as follows: first, the upper shell is fixed with a clamp, and then the position of the hole to be opened on the upper shell is determined to ensure that the position of the positioning hole corresponds to the positioning pin 331 on the lower end face of each first mounting plate 33, and is marked; then, a hole punch is used to punch holes at the marked positions in the above steps, and the hole depth is matched with the length of the positioning pin 331.

[0034] In one embodiment of this utility model, the lower end face of the bottom shell is provided with a mounting boss 21, which can be used to install the aerator in the gap 4. Limiting plates 211 are provided on both sides of the mounting boss 21 to limit the vertical displacement of the aerator.

[0035] In one embodiment of this utility model, a connection port 7 is provided in the middle of the mounting boss 21, and a sealing ring 8 is fitted on the connection port 7.

[0036] In one embodiment of this utility model, when replacing the diaphragm, the positioning pins 331 on the lower end face of the first mounting plate 33 are first inserted into the positioning holes of the aerator; then, by rotating the operating rod 31, each of the first mounting plates 33 is rotated, thereby disassembling the bottom shell and the upper shell of the aerator, and then replacing the diaphragm.

[0037] In one embodiment of this utility model, after the diaphragm is replaced, the positioning pins 331 on the lower end face of the first mounting plate 33 are inserted into the positioning holes of the aerator. The first mounting plates 33 are rotated by rotating the operating rod 31 in the opposite direction, thereby assembling the bottom shell and the upper shell of the aerator. This not only saves time and effort and facilitates maintenance, but also effectively controls maintenance costs and improves efficiency.

[0038] In one embodiment of this utility model, pads 6 are provided at both ends of the second mounting plate 12, which not only improves the stability of the second mounting plate 12, but also avoids obstruction when installing the aerator in the gap 4.

[0039] Although embodiments of the present invention have been shown and described, those skilled in the art will understand 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 claims and their equivalents.
