Embodiment 1

[0029] Example 1, see Figure 1 to Figure 4 , the square plate diffuser includes a square frame 13, an air connector 12 installed on the outside of the square frame 13, a diaphragm 14 located in the frame 13, the diaphragm 14 covers the space inside the entire frame, and the diaphragm 14 is EPDM diaphragm with PTFE coating.

[0030] The installation method of the square plate diffuser is connected by belt fasteners 15. The belt fasteners 15 have a symmetrical structure, and the belt fasteners 15 include two symmetrically arranged connecting pieces 16 and two fixing holes 19. , the two fixing holes 19 are respectively located on the outer sides of the two connecting pieces 16 .

[0031] Two fixing holes 19 are used to connect with the outside world, such as being installed on the ground by bolts, and two connecting pieces 16 are used to connect with the square plate type air diffuser. To support the bottom of the square plate type air diffuser, the insert block 17 is used for...

Embodiment 2

[0032] Example 2, see Figure 5 to Figure 7 , the square plate diffuser includes a square frame body 21, an air connector 22 installed inside the square frame body 21, a diaphragm 24 located in the frame body 21, the diaphragm 24 covers the space inside the entire square frame body, and the diaphragm 24 EPDM diaphragm with PTFE coating.

[0033] The installation method of the square plate diffuser is connected by a belt fastener 25. The belt fastener 25 includes two symmetrically arranged Z-shaped connectors. The lower surface of the upper end of the Z-shaped connector is fitted with a pressure block 26. The pressing block 26 presses the upper surface of the square frame body, and the lower end of the Z-shaped connector is connected with a bolt 29, and is connected with the outside through the bolt 29 for installation.

[0034] For the combination of square plate diffusers, see Figure 8 to Figure 12 .

[0035] Figure 8 The combined installation method of the Chinese squa...

Abstract

The invention provides a square plate type air radiation device and an installation mode. The square plate type air radiation device comprises a square frame body, an air connecting head and a diaphragm, wherein the air connecting head is arranged at the outer side or the inside of the square frame body; the diaphragm is positioned in the frame body; the diaphragm covers the space inside the whole frame body; the diaphragm is an EPDM (ethylene propylene diene monomer) diaphragm with a PTFE (polytetrafluoroethylene) coating; the installation mode of the square plate type air radiation device is the connection through a belt type fastener; the belt type fastener is of a symmetrical structure. The square plate type air radiation device disclosed by the invention has the advantages that the aeration area is larger; the oxygen utilization rate is higher; meanwhile, the EPDM diaphragm with the PTFE coating is used; the characteristics of good toughness and uniform air outlet of the EPDM are remained; meanwhile, the direct contact between the sewage and the EPDM is effectively isolated through the PTFE coating; the acid resistance and alkali resistance are high; the practicability on the sewage is higher; the combined installation mode is more flexible.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to a square-plate air diffuser and an installation method. Background technique [0002] Hypoxia is a common feature of polluted water bodies. Increasing the dissolved oxygen content of water body through aeration equipment is the first prerequisite for water environment management and ecological restoration, and it is also an indispensable basis for sewage treatment and aquaculture. [0003] Blast aeration is to send the compressed air from the air compressor to the air diffusion device installed at the bottom of the aeration tank through a series of pipeline systems. The air then escapes in the form of tiny bubbles and diffuses in the mixed liquid, making the Oxygen in the gas bubbles is transferred to the mixture. [0004] The rubber mold diffusers used in the market are generally disc-type and tube-type. The disc-type has a small service area and the tube-type has low resistance...
