Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment devices, and in particular to an aeration device for environmentally friendly sewage treatment and a method of using the same. Background Art

[0002] Eutrophication control and algae bloom control in lakes and rivers is a global issue. Under the interference of human activities, domestic sewage and various industrial wastewaters continue to flow into lakes and reservoirs. At the same time, farmland fertilizers washed by rainwater also pour in, making the nitrogen, phosphorus and other nutrients needed by organisms in lakes and rivers excessive, resulting in various water quality problems. According to incomplete statistics, about 90% of lakes in the country suffer from varying degrees of pollution. Human life and production activities inevitably produce a large amount of domestic sewage and industrial wastewater. With the rapid development of society, there are a large number of pollutants that are discharged into water bodies without proper treatment, causing serious pollution of the water environment. More and more people are beginning to study sewage treatment. Aeration devices are used to oxygenate and mix the mixed liquid of sewage and sludge. The existing aeration devices cannot increase the oxygen content in sewage quickly, resulting in the need to increase the oxygen content in sewage.

[0003] A disc aerator proposed in accordance with a Chinese utility model patent (application number: CN201820159537.6) aims to provide a disc aerator which can adjust the position of the disc as the water level changes, so that the mixing degree of sewage and air is always at an optimal value, and reduces the influence of the water level on the dissolved oxygen concentration in the sewage. The key points of the technical solution are that the mounting frame includes a frame and a mounting plate connected to the frame in a vertical direction, the motor reducer is fixed on the mounting plate, and a driving mechanism for driving the mounting plate to slide on the frame is also provided in the mounting frame. A limit plate for limiting the sliding distance of the mounting plate is provided on the frame, and the height of the disc and the height of contact with the water surface can be changed according to the change of the water level, so that the contact amount between the disc and the sewage is at an optimal value, and the mixing degree of sewage and air is ensured to be appropriate, thereby reducing the influence of the water level on the dissolved oxygen concentration in the sewage and improving the aeration effect of the sewage.

[0004] However, the device still has some shortcomings. 1. When the device aerates water bodies such as rivers and lakes, it cannot clean up the debris or aquatic plants floating on the surface of the water, which causes the garbage or aquatic plants to entangle the drive shaft and affect the aeration effect; 2. The flow effect is poor, which leads to poor aeration efficiency; 3. It cannot collect debris in the water body and has poor practicality. Therefore, we have made improvements to this and proposed an aeration device for environmentally friendly sewage treatment and its use method. Summary of the invention

[0022] The present invention also discloses a method for using an aeration device for environmentally friendly sewage treatment, which specifically comprises the following steps:

[0023] S1: When in use, the device is placed on the river surface as a whole. The buoyancy plate is set so that the device can float on the river surface. The device is fixed by cables to prevent it from drifting away with the water flow. The drive motor is started to drive the drive shaft to rotate, and then the transmission shaft is driven by the belt. The fifth shaft rotates, and the transmission shaft drives the first shaft to rotate through the bevel gear set, thereby driving the rotating disc body fixedly connected to the outer wall of the first shaft to rotate. As the rotating disc body rotates, the river water is lifted to achieve the purpose of aeration. At the same time, as the transmission shaft rotates, the second shaft is driven to rotate through the belt, and then the water flow is promoted through the flow-assisting blades, the flow rate of the river water is increased, and the activity of the river water is increased. In conjunction with the rotating disc body, the aeration effect is greatly increased;

[0024] S2: With the rotation of the first rotating shaft, the third rotating shaft is driven to rotate under the action of the belt and the pulley, and then the multiple output shafts are driven to rotate simultaneously through the bevel gear set, thereby driving the crushing blade to rotate, and then the water plants coming with the flow of river water are crushed. The crushed water plants continue to float with the rotation of the rotating disc body. Driven by the first rotating shaft, the lever rotates to promote the floating of the water plants, thereby preventing the water plants from entangled with the rotating disc body and affecting the aeration work;

[0025] S3: At the same time, as the transmission shaft rotates, the fourth rotating shaft is driven to rotate through the bevel gear set, and then the connecting rod slidably connected to the fourth rotating shaft is driven to make a circular motion, and then the sliding frame connected to the connecting rod is driven to make an up and down reciprocating motion on the outer wall of the sliding rod under the action of the elastic member, and as the connecting rod rotates, the sliding rod is driven to reciprocate on the outer wall of the guide rod, so that when the sliding frame moves from left to right, the sliding frame rises, and the push rod at the top is higher than the water surface. As the reciprocating motion continues, when the sliding frame moves from right to left, the sliding frame sinks, and the push rod is lower than the water surface, and will not push the water grass in the opposite direction. Then, when the sliding frame moves from left to right, the crushed water grass is pushed into the collection bucket through the push rod;

[0026] S4: Driven by the driving shaft, the fifth rotating shaft is driven to rotate through the belt, and then the collecting bucket is driven to rotate through the tray and the slot, and then the water in the aquatic plants is thrown out to the collecting bin, discharged through the water pump, and the river water is prevented from flowing back under the action of the one-way valve. When the collecting bucket is full, the collecting bucket is pulled out from the inside of the collecting box through the towing hook, which is easy to use, and can collect aquatic plants and garbage in the river water, increasing the practicality of the device.

[0027] In the scheme of this application:

[0028] 1. The front cutting component is linked with the rotating disc aeration component. When the rotating disc body is working, it is linked with the output shaft through the transmission component, and then the crushing blade crushes the waterweed and garbage, so that the waterweed and garbage coming with the flow of river water can be crushed, and the waterweed and garbage are prevented from entangled in the rotating disc and affecting the aeration efficiency. It solves the problem that when aerating rivers, lakes and other water bodies, it is impossible to clean up the debris or waterweed floating on the water surface, which causes the garbage or waterweed to entangle the drive shaft and affect the aeration effect;

[0029] 2. The flow-aiding component is linked with the disc aeration component. When aeration is performed, it is linked with the second rotating shaft to propel the river water through the flow-aiding blades, thereby increasing the flow rate and activity of the river water. In combination with the disc aeration component, the aeration effect of the river water is greatly increased, solving the problem of poor flow-pushing effect and thus poor aeration efficiency.

[0030] 3. Through the linkage between the pushing component and the collecting component, the push rod can push the broken aquatic plants and garbage into the collecting bucket while drying the aquatic plants, and the water is thrown out to the collecting bin and discharged through the water pump. The one-way valve can prevent the river water from flowing back. When the collecting bucket is full, the collecting bucket can be pulled out from the inside of the collecting box by the towing hook and poured out, which solves the problem of being unable to collect debris in the water and poor practicality.
