Description

Technical Field

[0001] This utility model relates to the field of wastewater homogenization tank technology, and in particular to a high-efficiency aquaculture wastewater homogenization tank. Background Technology

[0002] The equalization tank for livestock wastewater is an important pretreatment unit in the livestock wastewater treatment system. Its main function is to equalize the water quality and quantity of the wastewater by adjusting it. Livestock wastewater (such as manure and flushing water from livestock and poultry farming) is usually characterized by large fluctuations in water quality (such as significant differences in the concentration of organic matter and suspended solids at different times). The equalization tank makes the water composition uniform through mixing and stirring, so as to avoid the subsequent treatment equipment from being affected by drastic changes in water quality.

[0003] Existing homogenizing tanks often use mechanical paddle stirring or aeration to mix sediments. Currently, aeration pipes and stirring rods are usually placed at the bottom of the homogenizing tank to stir the wastewater and achieve homogenization. However, when the sediment concentration is high, the high concentration of sediment will limit the aeration area, resulting in a decrease in aeration efficiency and an increase in aeration energy consumption. At the same time, it will bring huge resistance to the stirring rod, causing a surge in stirring load and aggravating component wear. In the initial stirring, it is also difficult to quickly break up the sediment layer caused by sediment deposition, affecting the treatment efficiency and equipment life of the homogenizing tank. Therefore, a high-efficiency aquaculture wastewater homogenizing tank is proposed. Utility Model Content

[0005] In view of the problems existing in the above-mentioned high-efficiency aquaculture wastewater homogenization tank, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a high-efficiency aquaculture wastewater homogenization tank, which is suitable for solving the problem that when the concentration of sediment inside the homogenization tank is high, the high concentration of sediment will limit the aeration area and cause a surge in the stirring load, making it difficult to quickly break up the sediment layer caused by sediment deposition during the initial stirring, thus affecting the treatment efficiency and equipment life of the homogenization tank.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a high-efficiency aquaculture wastewater homogenization tank, comprising:

[0008] Homogeneous circular pool;

[0010] An aeration and stirring unit is installed at the bottom of the output ends of the two hydraulic telescopic cylinders. The aeration and stirring unit includes a stirring section and an aeration section, both of which are used to stir the sediment.

A servo motor is fixedly installed at the bottom of the inner cavity of the support frame. The output end of the servo motor rotates through the support frame and is fixedly connected to a hollow main shaft. Multiple stirring blades are fixedly connected to the tube wall of the hollow main shaft.

[0031] Example 1

[0032] Reference Figures 1-3 The first embodiment of this utility model provides a high-efficiency aquaculture wastewater homogenizing tank that can gradually immerse the sediment layer from a high position, thereby reducing the burden on the stirring and aeration parts in the initial stage of stirring and ensuring the uniformity of mixing. It includes: a homogenizing circular tank 100, a lifting unit 200 and an aeration and stirring unit 300.

[0033] The lifting unit 200 includes a support frame 201 fixedly connected to the top of the homogeneous circular pool 100. Two hydraulic telescopic cylinders 202 are fixedly installed on the top of the support frame 201, and the output ends of the two hydraulic telescopic cylinders 202 slide through the support frame 201.

[0034] An aeration and stirring unit 300 is installed at the bottom of the output end of the two hydraulic telescopic cylinders 202. The aeration and stirring unit 300 includes a stirring part 301 and an aeration part 302, both of which are used to stir the sediment.

[0035] Aquaculture wastewater is discharged into the homogenizing circular tank 100. During the mixing process, two hydraulic telescopic cylinders 202 fixed on the support frame 201 are started synchronously. Their output ends drive the aeration and stirring unit 300 connected to the output end to rise and fall vertically. The stirring part 301 in the aeration and stirring unit 300 stirs the sediment through mechanical stirring, while the aeration part 302 releases air bubbles to generate air flotation and water flow disturbance. As the hydraulic telescopic cylinders 202 drive the aeration and stirring unit 300 to descend, the stirring part 301 and the aeration part 302 start to process the upper sediment to avoid the stirring part 301 and the aeration part 302 directly contacting a large amount of sediment, which would cause an operational burden. The sediment at different depths in the tank is stirred gradually downwards to reduce the workload of the stirring part 301 and the aeration part 302, thereby improving the equipment life. This allows the entire homogenizing circular tank 100 to fully mix and homogenize the internal sediment for a long time with high efficiency.

[0036] Example 2

[0037] Reference Figure 1 and Figure 2 This is the second embodiment of the present invention. Unlike the previous embodiment, the bottom of the side wall of the homogenized circular pool 100 is fixedly connected to a sewage pipe 101, and a valve is fitted on the sewage pipe 101.

[0038] By opening the valve, the wastewater in the homogenized circular pool 100 can be discharged through the drain pipe 101.

[0039] The inner wall of the homogenizing circular pool 100 is fixedly connected to a protective tube 102, and a turbidity meter 103 is fixedly installed on the top of the protective tube 102. The turbidity sensor of the turbidity meter 103 passes through the protective tube 102 and is close to the bottom of the inner cavity of the homogenizing circular pool 100.

[0040] The protective tube 102 provides protection for the turbidity sensor of the turbidity meter 103, preventing it from being damaged by direct contact with sediments and impurities in the aquaculture wastewater. The turbidity meter 103 consists of general standard parts or components known to those skilled in the art. As the aeration and stirring unit 300 stirs and mixes the sediments, the turbidity meter 103 can continuously detect the turbidity changes of the wastewater at different stages and transmit the data back. Operators or control systems can judge the homogenization effect based on the turbidity data. If the turbidity does not reach the set standard, the aeration and stirring unit 300 can be controlled to continue working. If the standard is reached, subsequent treatment processes can be carried out.

[0041] Example 3

[0042] Reference Figure 2 and Figure 3This is the third embodiment of the present invention. Unlike the previous embodiment, the stirring part 301 includes a support frame 301a fixedly installed at the bottom of the output end of the two hydraulic telescopic cylinders 202. A servo motor 301b is fixedly installed at the bottom of the inner cavity of the support frame 301a. The output end of the servo motor 301b rotates through the support frame 301a and is fixedly connected to a hollow main shaft 301c. Multiple stirring blades 301d are fixedly connected to the tube wall of the hollow main shaft 301c.

[0043] After the servo motor 301b at the bottom of the inner cavity of the support frame 301a is started, the output end drives the hollow main shaft 301c connected to it to rotate at high speed, which in turn drives multiple stirring blades 301d fixed on the tube wall of the hollow main shaft 301c to rotate synchronously. The stirring blades 301d stir the sediment in the homogenized circular pool through the mechanical force generated by the rotation, so as to achieve preliminary mixing.

[0044] In addition, the aeration unit 302 includes a hollow hood 302a, which is fixedly sleeved to the hollow main shaft 301c by sealing bearings 302b at the top and bottom. The tube wall of the hollow main shaft 301c has a pair of air inlets located inside the hollow hood 302a. The side wall of the hollow hood 302a is fixedly connected to an air inlet pipe 302c, which passes through the support frame 301a and extends out from inside the support frame 301a. The tube wall of the hollow main shaft 301c is fixedly connected to multiple aeration pipes 302d.

[0045] The hollow cover 302a ensures the airtightness of gas transmission through the sealing bearings 302b at the top and bottom. Gas from an external gas source enters the hollow cover 302a through the air inlet pipe 302c. The air inlet pipe 302c can fix the hollow cover 302a to prevent it from rotating. The gas inside the hollow cover 302a then enters the inner cavity of the hollow main shaft 301c through the air inlet hole opened in the tube wall. Finally, the gas is discharged from multiple aeration pipes 302d on the tube wall of the hollow main shaft 301c, forming bubbles in the water. These bubbles generate air flotation and water flow disturbance during their rise, further promoting the dispersion and mixing of sediment. The aeration pipes 302d can rotate synchronously with the hollow main shaft 301c, thereby cooperating with the stirring part 301 to improve the homogenization effect.

[0046] Example 4

[0047] Reference Figure 1 and Figure 3 This is the fourth embodiment of the present invention. Unlike the previous embodiment, the horizontal aeration pipe 302d is vertically aligned with the adjacent stirring plate 301d above it, and the vertical aeration pipes 302d are arranged in a ring-shaped staggered distribution.

[0048] By aligning the horizontal aeration pipes 302d with the vertically aligned stirring plates 301d, the aeration bubble clusters can directly act on the water flow area formed by the stirring plates 301d, thereby enhancing the suspension and diffusion effect on sediments. The vertically arranged, ring-shaped, staggered stirring plates 301d can disperse the aeration range of multiple aeration pipes 302d, thereby increasing the aeration range and reducing dead zones, ensuring that sediments at different depths can be fully sheared and mixed.

[0049] Each aeration pipe 302d has a support ring 303 fixedly sleeved on its wall, and the top of each support ring 303 is fixed to the bottom of the corresponding stirring plate 301d.

[0050] The support ring 303 is used to rigidly connect the aeration pipe 302d to the stirring plate 301d to enhance the structural stability of the aeration pipe 302d under the impact of water flow and prevent the hollow aeration pipe 302d from loosening or breaking due to vibration.

[0051] In addition, a T-shaped rod 304 is fixedly connected to the bottom end of the hollow spindle 301c, and multiple loose rods 305 are fixedly connected to the bottom of the rod wall of the T-shaped rod 304.

[0052] When the hollow main shaft 301c drives the T-shaped rod 304 to sink to the upper surface of the sediment layer, the loosening rod 305 inserts into the sludge layer at the bottom of the pool. The hollow main shaft 301c can drive multiple loosening rods 305 to rotate through the T-shaped rod 304. The surface and bottom of the loosening rod 305 are rounded, so that the loosening rod 305, together with the air bubbles sprayed from the bottom of the aeration pipe 302d, can break up the clumps of sludge to ensure the homogeneity of the wastewater in the whole pool.

[0053] During use, the aquaculture wastewater is first discharged into the homogenization circular tank 100. During homogenization, two hydraulic telescopic cylinders 202 are activated, driving the aeration and stirring unit 300 to rise and fall vertically, stirring the sediment from top to bottom to avoid the equipment directly contacting a large amount of sediment and causing operational burden. The servo motor 301b drives the hollow main shaft 301c and stirring plate 301d to rotate, mechanically stirring the sediment. At the same time, the gas from the external air source enters the hollow cover 302a through the air inlet pipe 302c. The gas in the hollow cover 302a then enters the inner cavity of the hollow main shaft 301c through the air inlet hole opened in the pipe wall of the hollow main shaft 301c. Subsequently, the air bubbles are released through the hollow main shaft 301c and the aeration pipe 302d, generating air flotation and water flow disturbance.

[0054] As the hollow main shaft 301c descends, the loosening rod 305 at the bottom of the T-shaped rod 304 can be inserted into the upper sediment layer. With the rotation of the hollow main shaft 301c, the sludge accumulated at the bottom of the pool is broken up. The turbidity meter 103 can monitor the turbidity of the wastewater in real time and provide feedback data. The operator or control system judges the homogenization effect based on this. If the standard is not met, the aeration and stirring unit 300 is controlled to continue working. After homogenization is completed, the servo motor 301b stops rotating, and the hydraulic telescopic cylinder 202 drives the aeration and stirring unit 300 to rise vertically, so that the bottom aeration pipe 302d is away from the sediment layer to reduce the blockage of the aeration pipe 302d. After the homogenization standard is met, the drain pipe 101 valve can be opened to discharge the homogenized wastewater.

[0055] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
