Description

Technical Field

[0001] The invention relates to the technical field of water quality improvement devices, in particular to a layered mixing and oxygenating water quality improvement device. Background Art

[0002] Due to the low mobility of water in inland lakes or reservoirs, many organic matter, nitrogen, phosphorus and other nutrients are deposited and gathered in reservoirs and lakes, providing sufficient nutrition for phytoplankton such as algae. At the same time, due to the low mobility of water, algae can stay stably in the surface water, and the algae can receive sufficient light and reproduce in large numbers, which brings about the problem of eutrophication of water bodies. Due to the large water depth and low mobility of water quality improvement devices, water quality improvement devices are prone to water stratification. After stratification, the upper and lower water bodies are relatively static, lacking exchange and mass transfer, and the oxygen consumption of water bodies and bottom muds, resulting in the bottom water body being in anoxic state. Under the reducing conditions of water quality improvement devices, nitrogen, phosphorus, iron, manganese and other substances in the bottom mud are dissolved and released into the water body, sulfate is reduced to sulfide, and organic matter is anaerobically decomposed into organic acid, etc., causing secondary pollution of the bottom water body and deterioration of the aquatic ecological environment.

[0003] In the prior art, water quality in-situ remediation technology can be used to improve the oxygenation of water bodies.

[0016] 1.

The rotation of the air supply ring 32 can make the oxygen delivery more uniform, and the rotation of the bottom ring 33 drives the scraper 311 to move to clean the air outlet 310 to prevent impurities in the water from clogging the air outlet 310. The outer surfaces of the first motor 36 and the second motor 51 are both waterproofed.

[0035] In this embodiment, the connecting component 4 also includes a through groove 42, and the through groove 42 is opened on the surface of the connecting frame 41, and the air supply pipe 2 and the expansion pipe 21 slide through the through groove 42, and the two sides and the outer end of the through groove 42 are slidably inserted with a plug rod 44, and one end of the plug rod 44 is fixed with a sliding ball 43, and the sliding ball 43 slides along the outer wall of the air supply pipe 2 and the expansion pipe 21, and the outer end of the plug rod 44 is sleeved with a second spring 45, and the other end of the second spring 45 is fixedly connected to the outer wall of the connecting frame 41, and a cross plate is fixed on the top of the plug pipe 23, and electric push rods 48 are fixedly installed on both sides of the outer end of the connecting frame 41, and the extended end of the electric push rod 48 is in compression contact with the cross plate of the plug pipe 23, and the tail end of the plug pipe 23 is fixed with a first spring 24, and the first spring 24 is sleeved on the surface of the cross tube 22 and fixedly connected to the air supply pipe 2, and on the periphery of the air supply ring 32 There is also a rotating ring, which is not numbered in the figure. It is a channel connecting the inner cavity of the air supply ring 32 and the inner tube 47, and can maintain the connection between the inner tube 47 and the inside of the air supply ring 32 when the air supply ring 32 rotates. The connecting frame 41 is sleeved on the periphery of the air supply pipe 2, and the top of the expansion tube 21 is a cone. Through the sliding of three sets of sliding balls 43 and the insertion rod 44, the sliding ball 43 can be kept in sliding contact with the outer surface of the air supply pipe 2 or the expansion tube 21, and adaptive adjustment can be made, and it plays a certain role in limiting and guiding. When the inner tube 47 corresponds to the horizontal tube 22 in a straight line, the insertion tube 23 is pushed to move by the electric push rod 48 and inserted into the gap between the connecting tube 46 and the inner tube 47, so as to realize the connection between the horizontal tube 22 and the inner tube 47.

The position of the spring is not shown in the figure, that is, a rebound force is given to the first sealing plate 25. Under the traction of the connecting rope 26 and the second sealing plate 27, the first sealing plate 25 moves to the highest point where the expansion tube 21 is connected to the air supply tube 2, blocking the air supply tube 2 from continuing to supply air to the expansion tube 21. In a normal state, the insertion tube 23 is sleeved on the cross tube 22, and the second sealing plate 27 blocks the outlet end of the cross tube 22, so that oxygen will not flow out of the cross tube 22. The first sealing plate 25 is located inside the expansion tube 21. Because the diameter of the expansion tube 21 is larger than that of the air supply tube 2, oxygen can flow downward along the air supply tube 2 and the expansion tube 21, thereby completing the adjustment of the gas delivery path at the corresponding position.

[0037] When using the device, first arrange the water-lifting aerator body 1 at the designated position, then install the air supply assembly 3 and the connecting assembly 4 on the periphery of the water-lifting aerator body 1 to connect with the air supply pipe 2.

The cannula 23 is pushed to move and inserted into the gap between the connecting tube 46 and the inner tube 47, so as to realize the connection between the transverse tube 22 and the inner tube 47. At this time, oxygen can be directly delivered to the inside of the air supply ring 32. The expansion tube 21 can be set at multiple locations on the air supply tube 2 to facilitate oxygen injection into water bodies at different depths. Under the traction of the connecting rope 26 and the second sealing plate 27, the first sealing plate 25 moves to the highest point where the expansion tube 21 and the air supply tube 2 are connected, blocking the air supply tube 2 from continuing to supply air to the expansion tube 21. In a normal state, the cannula 23 is sleeved on the transverse tube 22, and the second sealing plate 27 blocks the outlet end of the transverse tube 22, so that oxygen will not flow out of the transverse tube 22. The first sealing plate 25 is located inside the expansion tube 21.
