It should be understood that the specific implementation described here is only used to illustrate and explain the embodiment of the utility model, and is not used to limit the embodiment of the utility model.

[0042] Figure 1-Figure 6It is an accompanying drawing provided according to the embodiment of the utility model. In the utility model, the slat-type microporous aerator may include: a support frame 1, an arc-shaped plate 4, a rubber aeration membrane 6, a first connecting pipe 8 and a second connecting pipe 9. An air distribution channel 2 may be provided inside the support frame 1. Ventilation pipes 3 may be connected to both ends of the air distribution channel 2. The arc-shaped plate 4 may be arranged at the top of the air distribution channel. The four walls of the arc-shaped plate 4 may be connected to the support frame 1, and may be connected to the air distribution channel 2 through the air outlet pipe 5. The rubber aeration membrane 6 may cover the arc-shaped plate 4 and the air outlet pipe 5. The rubber aeration membrane 6 may be densely covered with staggered aeration holes 7. The first connecting pipe 8 may be arranged on one side of the support frame 1, and may pass through the support frame 1 to be connected to the air distribution channel 2. The second connecting pipe 9 may be arranged on the other side of the support frame 1, and may pass through the support frame 1 to be connected to the air distribution channel 2. Two adjacent slat-type microporous aerators can be connected to each other by connecting the adjacent first connecting pipe 8 and the second connecting pipe 9 through the connecting piece 10. In the utility model, a certain space can be formed between the rubber aeration membrane 6 and the arc plate 4, and the air in the air distribution channel 2 can enter the space between the arc plate 4 and the rubber aeration membrane 6 through the outlet pipe 5, and then be discharged from the aeration hole 7 of the rubber aeration membrane 6. The first connecting pipe 8 and the second connecting pipe 9 can both be connected to the air distribution channel 2. When two adjacent slat-type microporous aerators are connected through the first connecting pipe 8 and the second connecting pipe 9, the air in the air distribution channel 2 can enter the adjacent air distribution channel 2 through the first connecting pipe 8 and the second connecting pipe 9 connected to each other. When the first connecting pipe 8, the second connecting pipe 9 and the ventilation pipe 3 are not connected, they can be blocked by a plug to prevent air leakage. The slat-type microporous aerator can be quickly connected to adjacent slat-type microporous aerators through the connecting piece 10, thus avoiding the shortcomings of the existing aerator installation procedure being complicated and slow in construction.

[0043] In one embodiment of the utility model, an external thread may be provided on the first connecting tube 8. The connecting member 10 may include: a first insert tube 101, a second insert tube 102, and a rotating nut 104. The first insert tube 101 may be arranged at the top of the first connecting tube 8.

When the first insert tube 101 is inserted into the annular groove 103, the top of the second insert tube 102 may just abut against the top of the first connecting tube 8, so that the first connecting tube 8 and the second connecting tube 9 can be staggered and connected to achieve a good sealing effect. The rotating nut 104 can be rotatably arranged on the top of the second connecting tube 9. When the first inserting tube 101 is inserted into the annular groove 103, the rotating nut 104 can be threadedly connected with the first connecting tube 8, thereby connecting the first connecting tube 8 and the second connecting tube 9.

[0044] In one embodiment of the present invention, the lath-type microporous aerator may include a first sealing ring 11. The first sealing ring 11 may be disposed at the bottom of the annular groove 103, thereby preventing air from leaking from the connection between the first connecting pipe 8 and the second connecting pipe 9.

[0045] In one embodiment of the present invention, the lath-type microporous aerator may include a second sealing ring 12. The second sealing ring 12 may be disposed on the top of the second inserting tube 102, thereby further preventing air from leaking from the connection between the first connecting tube 8 and the second connecting tube 9.

The position of the support frame 1 corresponding to the rubber aeration membrane 6 may be provided with a card slot 13 of the same shape as the rubber aeration membrane 6. The rubber aeration membrane 6 may be inserted into the support frame 1 along the card slot 13. Because the bottom cross-sections of the two sides of the rubber aeration membrane 6 are circular, when inserted into the support frame 1, it can be mutually limited with the card slot 13, and is not easy to fall off or leak.

[0047] In one embodiment of the utility model, the slat-type microporous aerator may include a block 14. The block 14 may be inserted into the slot 13 from both ends of the slot 13, and a groove that is consistent with the cross-sectional shape of the rubber aeration membrane 6 may be provided in the block 14, so that both ends of the rubber aeration membrane 6 are respectively inserted into one block 14, so that the block 14 can fix both ends of the rubber aeration membrane 6.

[0048] In one embodiment of the present invention, the strip-type microporous aerator may include a bolt 15. The bolt 15 may be fixed to the top of the clamping block 14, so that the clamping block 14 may be fixed to the arc-shaped plate 4.

[0049] In one embodiment of the utility model, the number of the first connecting tube 8 and the second connecting tube 9 can be multiple, and can be evenly arranged on the side of the support frame 1. The number of the connecting pieces 10 can be consistent with the number of the first connecting tubes 8, so that the adjacent first connecting tubes 8 and second connecting tubes 9 can be connected, so that the air distribution channels 2 in the two adjacent slat-type microporous aerators can be better connected, and further the air can flow more smoothly.

[0050] In one embodiment of the present invention, the slat-type microporous aerator may include a check valve 16, which may be disposed in the air outlet pipe 5. The check valve 16 may prevent sewage from flowing back into the air distribution channel 2 to affect ventilation.

[0051] Through the above technical scheme, the support frame of a splicable slat-type microporous aerator provided by the utility model can be provided with an air distribution channel inside, and ventilation pipes can be connected to the two ends of the air distribution channel. The arc plate can be arranged at the top of the air distribution channel. The four walls of the arc plate can be connected to the support frame, and can be connected to the air distribution channel through an air outlet pipe. The rubber aeration membrane can cover the arc plate and the air outlet pipe, and the rubber aeration membrane can be densely covered with staggered aeration holes. The air in the air distribution channel can enter the space between the arc plate and the rubber aeration membrane through the air outlet pipe, and then be discharged through the aeration holes of the rubber aeration membrane. The first connecting pipe can be arranged on one side of the support frame, and can pass through the support frame to connect to the air distribution channel. The second connecting pipe can be arranged on the other side of the support frame, and can pass through the support frame to connect to the air distribution channel. Two adjacent slat-type microporous aerators can connect the adjacent first connecting pipe and the second connecting pipe through a connecting piece, so that the connection of two adjacent slat-type microporous aerators can be realized. The microporous aerators can be assembled together to quickly complete the installation.
