Description

Technical Field

[0001] The utility model specifically relates to an aeration device for a sewage purification grit chamber. Background Art

[0002] Water purification grit chamber is a common water treatment facility used to remove suspended matter, mud and other impurities in water. Its main function is to achieve preliminary solid matter removal by allowing wastewater to stay in the tank for a period of time so that suspended particles and mud settle to the bottom. However, in some cases, the effect of the grit chamber is limited by the dissolved oxygen level, and aeration is needed to improve the treatment effect.

[0003] When installing existing water aeration structures, the aeration head is usually installed directly on the gas flow pipe through an installation pipe. The height of the aeration head is not easy to adjust, resulting in the gas not being able to flow out well at a specific position during aeration. It is necessary to redesign installation pipes of different heights to adjust the height position of the aeration head. The installation is relatively troublesome and time-consuming, and the use effect is not good. For this reason, we propose an aeration device for a sewage purification grit tank.

[0025] A main pipeline 1, a plurality of branch pipelines 2 are evenly distributed along the axial direction of the side wall of the main pipeline 1;

[0026] The height adjustment mechanism 3 can be detachably installed on the branch pipe 2, which is convenient for later disassembly and maintenance, and an aeration mechanism 4 for aeration is arranged on the top of the height adjustment mechanism 3. During installation, the aeration height of the aeration mechanism 4 is adjusted through the height adjustment mechanism 3, so that the height position of the aeration mechanism 4 can be accurately adjusted for aeration according to the actual aeration position required.

[0027] In this embodiment, preferably, the height adjustment mechanism 3 includes a first hollow tube 31, an external thread 311, a second hollow tube 32 and a sealing member 33. The first hollow tube 31 is connected to the mounting platform 21 on the branch pipe 2 through the external thread 311 on its outer surface. The upper inner end of the first hollow tube 31 is connected to the second hollow tube 32 through threaded cooperation, so that the height of the aeration mechanism 4 can be adjusted during installation, and the second hollow tube 32 is fixed to the aeration mechanism 4. A sealing member 33 is sleeved on the outer side of the second hollow tube 32, and a rubber block 34 is arranged on the inner side of the sealing member 33, so as to seal the connection between the first hollow tube 31 and the second hollow tube 32.

[0028] In this embodiment, preferably, a sealing skirt 312 is fixed to the outer surface of the first hollow tube 31, and a sealing gasket 313 that contacts the mounting platform 21 is provided at the inner top of the sealing skirt 312 to better seal the connection between the first hollow tube 31 and the second hollow tube 32 to avoid air leakage.

[0029] In this embodiment, preferably, the rubber block 34 is annular, and is provided with an inclined surface in contact with the seal 33, so that when the height of the seal 33 is adjusted by rotation, the seal 33 can contact the inclined surface on the rubber block 34, so that the rubber block 34 and the second hollow tube 32 are in close contact, thereby increasing the friction between the two.

[0030] In the present embodiment, preferably, the aeration mechanism 4 includes an aeration head 41, an air dividing block 42, a first aeration hole 43 and an air dividing block 42. The aeration head 41 is fixed to the top of the height adjustment mechanism 3, and the lower inner end of the aeration head 41 is provided with an air dividing block 42 which is connected to the inner side of the height adjustment mechanism 3, so as to facilitate the diversion of the gas flowing out of the second hollow tube 32. The air dividing block 42 is fixed to the middle inner side of the aeration head 41 and corresponds to the air dividing block 42. The aeration head 41 is provided with a first aeration hole 43 for facilitating aeration.

[0031] In this embodiment, preferably, the cross section of the gas separation block 42 is "D"-shaped, and a second aeration hole is opened inside the gas separation block 42 to facilitate better aeration when the gas is diverted.

[0032] In this embodiment, preferably, a pointed rod 45 is fixed to the lower surface of the gas separation block 42 to facilitate the segmentation of large bubbles into multiple dense small bubbles, so as to increase the contact area between the multiple small bubbles and the water body, thereby increasing the oxygen dissolving effect of the water body.

[0034] The working principle and use process of the utility model are as follows: when in use, the first hollow tube 31 is connected to the mounting platform 21 through the external thread 311, at this time, the sealing skirt 312 abuts against the sealing gasket 313 and is in close contact with the mounting platform 21, the sealing member 33 is loosened upward, the second hollow tube 32 is matched with the first hollow tube 31 through the threaded portion, the second hollow tube 32 is screwed up and down to adjust the height of the aeration mechanism 4, and then the sealing member 33 is screwed downward to make the sealing member 33 abut against the inclined surface on the rubber block 34, so that the rubber block 34 and the aeration mechanism 4 are in close contact. The second hollow tube 32 is in close contact with each other to limit the rotation of the second hollow tube 32, and the connection between the second hollow tube 32 and the first hollow tube 31 can be sealed. During aeration, high-pressure gas flows to the gas distributor block 42 through the main pipe 1, the branch pipe 2, the first hollow tube 31 and the second hollow tube 32, and is ejected from the gas distributor block 42 to the inside of the aeration head 41. The pointed rod 45, the gas distributor block 42 and the first aeration hole 43 can cut the gas to make the bubbles smaller and more numerous during aeration, so as to increase the contact area with the water body and increase the dissolved oxygen content in the water body.
