Description

Technical Field

[0001] The present invention relates to the field of water aeration devices, and particularly to a gasless convection type aeration device. Background Art

[0002] At present, the aeration methods of aeration devices are mainly divided into three categories. The first type of aeration method is to introduce air into the water body through a blower and refine it into small bubbles through an aeration disc to increase the contact surface between the gas and the water body. Part of the oxygen in the air is dissolved in the water, thereby improving the dissolved oxygen level of the water body. This method has three disadvantages. The first disadvantage is low efficiency. The oxygen content in the introduced air is only about 21%, and the other 79% is nitrogen and other trace gases. Although it is refined through the aeration disc, the efficiency is still relatively low. The second disadvantage is high energy consumption. Not only do we need to press the extra 79% of useless gas into the aeration disc through mechanical energy, but also because it generally needs to be pressed more than 1 meter deep underwater, especially as the aeration depth increases, the required energy consumption is greater. The third disadvantage is relatively high noise. Blowers generally generate relatively high noise. The second type is to throw the water up by mechanical force to allow it to fully contact the air, thereby increasing the dissolved oxygen level. This method also has three disadvantages. The first disadvantage is high energy consumption. Stirring a large amount of water requires high energy consumption. The second disadvantage is high noise. The third disadvantage is that it can only solve the dissolved oxygen level of the surface water and cannot effectively improve the dissolved oxygen level of deeper water bodies. The third type is the method of using pure oxygen instead of air. This method effectively solves the problem of waste of energy consumption of 79% non-oxygen components and also improves the working efficiency of oxygenating the water body. However, it also has obvious disadvantages. The first disadvantage is high cost. Because the cost of oxygen production is high, storage and transportation both require costs, and it is difficult for farms in remote areas to apply it. The second disadvantage is that the safety factor of high-pressure oxygen cylinders is relatively low, and the probability of danger is relatively high. The third disadvantage is that the one-time equipment investment is relatively high, and it is difficult to promote.

[0003] In the prior art, the application publication number is CN114988593A, the application number is 202210481905X, and the invention name is a device for transporting surface water to deep layers for aeration. It can solve the problem that the oxygen content of deep water is lower than that of surface water by transporting surface water to deep water, but its dissolved oxygen efficiency is low, and the mixing and contact range between surface water and deep water is small. At the same time, it is not convenient to clean the water inlet pipe. Utility Model Content

[0004] The purpose of the present invention is to provide a water aeration device for the above problems, including:

[0005] A main floating body with a density less than that of water, and a water collection cavity is arranged inside the main floating body;

[0006] A number of perforated water suction pipes are located in the surface layer of the water body. One end of each perforated water suction pipe is connected to the main floating body, and the other end extends away from the main floating body. The perforated water suction pipe has a central channel inside. A plurality of water suction ports are provided on the pipe wall of the perforated water suction pipe. The surface water can enter the central channel through the water suction ports and enter the water collection cavity of the main floating body.

[0007] An oxygen delivery water pipe, one end of which is communicated with the water collection cavity of the main floating body, and the other end extends into the deep water layer.

[0008] An aeration water pump can make the surface water of the water body surface enter the water collection cavity through the water suction ports and be transported to the deep water layer at the end of the oxygen delivery water pipe.

[0009] In a preferred embodiment, the aeration water pump is located on the main floating body.

[0010] In a preferred embodiment, a water suction pipe floating ball is provided at the end of the perforated water suction pipe. One end of the water suction pipe floating ball is a one-way valve, and the other end is connected to the perforated water suction pipe. The one-way valve is set to prevent water from entering the water suction pipe and can be set to eject water from the water suction pipe.

[0011] In a preferred embodiment, the aperture size of the water suction holes of the perforated water suction pipe gradually decreases from the connection end of the water suction pipe floating ball to the main floating body end.

[0012] In a preferred embodiment, the aeration water pump is detachably connected to the main floating body.

[0013] In a preferred embodiment, the main floating body is made of foam material.

[0014] In a preferred embodiment, the water suction pipe floating ball is made of foam material, which can provide buoyancy for the perforated water suction pipe and keep the equipment balanced.

[0015] This application also discloses a water body aeration system, including:

[0016] The water body aeration equipment;

[0017] A water spraying device, which is connected to the end of the oxygen delivery water pipe and can spray the water in the oxygen delivery water pipe into the deep water layer.

[0018] In a preferred embodiment, the water spraying device includes:

[0019] A water spray pipe connector, which is connected to the end of the oxygen delivery water pipe; there is one or more water spray pipe connection ports on its side,

[0020] A perforated water spray pipe, which is a pipe with openings on both sides and sealed at the end, and is connected to the water spray pipe connection port.

[0021] In a preferred embodiment, an anchor body fixing ring is provided at the bottom of the water spray pipe connector.

[0022] The aeration water pump used in the present invention is a water pump with low energy consumption and low lift, which can reduce energy consumption. By using a suction pipe float ball with a one-way valve and reverse pumping water, small floating objects in the perforated suction pipe can be ejected, realizing automatic cleaning of the perforated suction pipe and keeping the pipeline unobstructed. One or more perforated suction pipes used are in a parallel relationship and are radially arranged in the surface water. The surface water inhaled for dissolving with the deep water has a wide range, and there will be no situation where only the dissolved oxygen level of a local water body is high. The perforated water spray pipe with openings on both sides has the same length as the perforated suction pipe. The ejected surface water is mixed with the deep water, and the dissolution range is wide. Moreover, the aperture size decreases sequentially from the top end, minimizing the difference in water output between the distal end and the proximal end. The present invention realizes high-efficiency improvement of the dissolved oxygen level of the entire water body only through the exchange of upper and lower layers of water, with higher efficiency; the equipment is simpler to use. Compared with an air compressor, it not only has lower energy consumption but also has a lower failure rate, and the management is simpler. Description of the Drawings

[0029] The present invention will be described in detail below with reference to the accompanying drawings.

[0030] This embodiment discloses a non-air convection aeration device, as Figure 1 shown: including: an aeration water pump 1, a perforated suction pipe 2, a suction pipe float ball 3, a main float body 4, an oxygen delivery pipe 5, a water spray pipe connector 6, and a perforated water spray pipe 7.

[0031] As Figure 1As shown, the oxygenation water pump 1 is a water pump with low energy consumption and low lift. Its water inlet is connected to the perforated suction pipe 2. The perforated suction pipe 2 is a water pipe with suction holes on both sides. Preferably, the aperture of the suction holes is 4 to 6 mm. Its material is hard PE, PVC and metal materials. The pipe diameter is 100 - 150 mm, and its length is 1.5 to 3.5 meters, and the pipe diameter is 50 to 80 mm, but it can be adjusted according to the specific implementation environment. Generally, when the pipe diameter is large, the length can be made longer; conversely, when the pipe diameter is small, it can be made shorter. The distance between the holes is preferably 100 - 200 mm. From the distal end to the proximal end, the aperture gradually becomes smaller. Opening holes on both sides not only ensures that the surface water can smoothly enter the pipeline, but also keeps the equipment rotating due to the reaction force during water absorption.

[0032] The end of the perforated suction pipe 2 is connected to the suction pipe float 3. The suction pipe float 3, preferably, is made of lightweight foam material. One end has an opening and is connected to the end of the perforated suction pipe 2, and the other end is a one-way valve. The function of the suction pipe float is to work together with the main float to make 4 / 5 of the suction pipe just immersed in water, so that the suction pipe can suck in the surface water to the maximum extent. At the same time, the suction pipe float can also keep the whole equipment balanced without tilting. According to the amount of small floating objects on the water surface, the equipment is set to pump water in the reverse direction regularly. For example, when the oxygenation water pump works for 0.5 - 1 hour, it automatically pumps water in the reverse direction for 3 - 10 seconds. When pumping water in the reverse direction, the one-way valve at the opening on one side of the suction pipe float opens, and the water sprayed in the reverse direction flushes the suction pipe and the suction holes once. The accumulated floating object particles and sundries are more likely to overflow from the opening, so the automatic cleaning of the suction pipe is realized by pumping water in the reverse direction, keeping the pipeline unobstructed.

[0033] The main float 4 is connected to the oxygenation water pump 1. Preferably, its material is lightweight foam material. The top of the oxygen delivery pipe 5 is connected to the water outlet of the oxygenation water pump 1. Preferably, its material is hard PE, PVC and metal materials, and the pipe diameter is 100 - 150 mm. The spray pipe connector 6 is connected to the bottom of the oxygen delivery pipe 5. Preferably, its material is stainless steel material. There are two or more spray pipe connection ports on its side, and there is an anchor fixing ring at its bottom. The perforated spray pipe 7 has holes on both sides and its top is closed. Preferably, its material is hard PE, PVC and metal materials. Its length is the same as that of the perforated suction pipe 2. Its pipe diameter is 40 to 60 mm, and the aperture of its spray holes gradually decreases from the top. Preferably, the aperture of the spray holes is 40 to 60 mm.

[0034] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
