[0002] Traditional circular aeration discs suffer from uneven bubble distribution and insufficient shear force, making it difficult to meet the special requirements of aerobic granular sludge processes for linear shear force. Existing elongated aeration units mostly use welding connections, which result in high costs for integral construction, a large amount of welding work, and difficulties in maintenance and replacement. In order to address the above-mentioned shortcomings, this application is proposed. Utility Model Content

The aeration branch pipe is provided with a sliding groove, and a sliding adjustment block connected to the male connector is provided in the sliding groove. By operating the sliding adjustment block, the male connector can be retracted into the aeration branch pipe, thereby allowing any section of the aeration branch pipe to be disassembled and assembled.

[0008] According to one embodiment of the present invention, the sliding adjustment block is provided with a threaded hole, and the sliding adjustment block can be fixed by mounting bolts.

[0009] According to one embodiment of the present invention, a sealing strip is provided on the mating surface of the elongated aeration support plate and / or the air distribution component.

[0016] Figure 2 This is a schematic diagram of the cross-sectional structure of a modular linear shear aeration device. Detailed Implementation

[0017] The following description is only intended to disclose the present invention so that those skilled in the art can implement it. The embodiments in the following description are merely examples, and those skilled in the art will conceive of other obvious modifications. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other solutions that do not depart from the spirit and scope of the present invention.

[0018] Example 1:

[0019] A modular linear shear aeration device, such as Figure 1 It includes an aeration branch pipe 1, a long strip aeration support plate 2, an air distribution component 3, and a fixing buckle 4.

[0020] The aeration branch pipe 1 and the long strip aeration support plate 2 are integrated into one unit to form an integrated structure. The integrated structure is provided with an air inlet 5 that is connected to the aeration branch pipe 1 at one end and extends to the end face of the long strip aeration support plate 2 at the other end. The dimensions of the integrated structure can be set to 500mm (length) * 200mm (width).

[0021] One end of the aeration branch pipe 1 is provided with a male connector 6, which is a pipe body with a diameter smaller than that of the aeration branch pipe 1, and the other end is provided with a female connector 7. The female connector 7 is preferably a part of the aeration branch pipe 1. The male connector 6 is inserted into the female connector 7 to realize the docking and assembly of multiple sets of aeration branch pipes 1.

[0022] The air distribution component 3 can be installed on the elongated aeration support plate 2. The fixing buckle 4 is used to fix the air distribution component 3 and the elongated aeration support plate 2. The air distribution component 3 is provided with a strip-shaped air slit 31. Preferably, a sealing strip 32 is provided on the mating surface of the elongated aeration support plate 2 and / or the air distribution component 3.

[0023] like Figure 2 The air distribution component 3 has protrusions on both sides of its edge. The fixing buckle 4 is a U-shaped buckle made of plastic or metal with a certain degree of elastic deformation performance. It has a groove that matches the protrusion. The fixing buckle 4 fastens the edges of the long strip aeration support plate 2 of the air distribution component 3 together to achieve a sealed assembly effect.

[0024] The air distribution surface of the air distribution component 3 is curved, but in other embodiments it can also be flat.

[0025] Optionally, the air distribution surface of the air distribution component 3 is an air distribution membrane or an air distribution plate. When using an air distribution plate, it is a rigid plate, and the material can be an engineering plastic (such as PP) plate with a thickness of 3-5mm, which is suitable for high-load conditions. When using an air distribution membrane, it is a flexible arc-shaped aeration membrane, and the material can be an EPDM rubber plate with a thickness of 3-5mm.

[0026] Several strip-shaped air gaps 31 are arranged in a row and in several rows. The strip-shaped air gaps 31 in adjacent rows are staggered to form a continuous linear air curtain. The linear distribution of air bubbles can form stable hydraulic shear and improve the formation rate of aerobic granular sludge. Preferably, the width of the strip-shaped air gaps 31 is 0.1~0.3mm, preferably 0.2mm, and the center distance of the strip-shaped air gaps 31 in the same row is 5~20mm.

[0027] Example 2:

[0028] Based on Example 1, in this example, the male connector 6 and the aeration branch pipe 1 are movably connected. The outer wall of the male connector 6 is provided with several sealing rings that contact the inner wall of the aeration branch pipe 1. The aeration branch pipe 1 is provided with a sliding groove 9, and a sliding adjustment block 8 connected to the male connector 6 is provided in the sliding groove 9. By operating the sliding adjustment block 8, the male connector 6 can be retracted into the aeration branch pipe 1, thereby allowing any section of the aeration branch pipe 1 to be disassembled and assembled. The sliding adjustment block 8 is provided with a threaded hole 10, which can be fixed by mounting bolts. The bolts achieve the fixing effect by tightening them against the aeration branch pipe 1, or bolt holes are provided on the aeration branch pipe 1.

[0029] When it is necessary to maintain or disassemble any of the modules, simply retract the corresponding module and the adjacent male connector 6 into the aeration branch pipe 1 to complete the disassembly.

The purpose of the present invention has been fully and effectively achieved. The functional and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations and modifications.
