Description

Technical Field

[0001] This utility model relates to the field of three-phase separator technology, and in particular to a backwashable three-phase separator. Background Technology

[0002] As is well known, wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Wastewater treatment is widely used in various fields such as urban construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, medical care, and catering. A three-phase separator is a device that can separate wastewater and plays a crucial role in sludge discharge.

[0003] However, in existing three-phase separators, the rising gas flow often carries tiny solid sludge particles during the gas separation stage. These sludge particles easily adhere to and gradually accumulate on key separation components inside the separator (such as the gas collection hood, baffles, or packing surface), eventually forming a stubborn blockage layer. This blockage not only directly hinders the smooth collection and discharge of gas but also severely restricts the continuous operating efficiency of the equipment.

[0004] Conventional maintenance methods either require frequent disassembly of equipment components for manual flushing, a cumbersome process that disrupts production; or attempt to flush only the visible upper separation structure from the top of the unit without disassembly. The latter method has serious drawbacks: the water flow is insufficient to effectively cover and remove sludge from the lower layers or internal structures. Instead, the flushed sludge may migrate downwards and accumulate more rapidly on the bottom components. This layer-by-layer migration and bottom accumulation of sludge continuously reduces the effective working area of ​​the lower separation structure, significantly lowering separation efficiency and ultimately reducing the overall processing capacity of the three-phase separation unit. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where the upper separation structure is rinsed, making it difficult for the water flow to effectively cover and remove the mud and sludge in the lower layer or inside the structure. Therefore, this invention proposes a backwashable three-phase separator.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a backwashable three-phase separator, including a tank, an exhaust assembly connected to the top of the tank, a slag discharge assembly connected to the bottom of the tank, a water inlet pipe connected to the bottom outer side of the tank, two separation assemblies arranged in the middle of the tank, forming a separation chamber between the two separation assemblies, a drain pipe connected to one side of the tank, the water inlet end of the drain pipe located in the separation chamber, a connecting pipe placed on one side of the outer side of the tank, one end of the connecting pipe passing through the tank and connected to a shell, a rotating disk connected to the bottom of the shell through a sealed bearing, and several nozzles connected to the bottom of the rotating disk, each nozzle having an adjustment mechanism.

[0008] Preferably, the nozzles are evenly distributed along the circumference of the rotating disk, and their nozzle direction is inclined downwards, pointing towards the surface of one of the separation components.

[0009] Preferably, the adjusting mechanism includes a fixing strip fixed inside the nozzle, a sealing plate placed at the bottom of the fixing strip, a long rod connected to the top of the sealing plate, one end of the long rod passing through the fixing strip and connected to a stop block, an elastic element provided at the bottom of the stop block, one end of the elastic element abutting against the fixing strip, and under normal conditions, the elastic element drives the sealing plate to move upward to close the water outlet of the nozzle.

[0010] Preferably, the elastic element is a cylindrical spring, and the elastic element is sleeved on the fixing strip.

[0011] Preferably, the outer side of the long rod is provided with a corrosion-resistant coating.

[0012] Preferably, the housing is disc-shaped, and a rotating shaft is connected inside the housing via a sealed bearing. A vortex blade is connected to the rotating shaft, and the connecting pipe is aligned with the vortex blade. One end of the rotating shaft is connected to the rotating disk.

[0013] Preferably, the inlet height of the drain pipe is located in the central area between the two separation components, and its inlet direction is perpendicular to the tank axis.

[0014] Preferably, the connecting pipe is connected to an external flushing water source or a high-pressure fluid source, and the water flows through the connecting pipe to impact the vortex blades, driving the rotating shaft and rotating disk to rotate.

[0015] The backwashable three-phase separator proposed in this utility model has the following advantages:

[0016] 1. High-pressure water enters the housing through the connecting pipe, driving the vortex blades to rotate with the rotating shaft. The rotating shaft drives the rotating disk to rotate, and several nozzles rotate with the rotating disk. At the same time, the adjusting mechanism pushes open the sealing plate under fluid pressure, increasing the range of water sprayed onto the surface of the separation component. This causes the water to be sprayed at an angle onto the surface of the separation component to break down dirt, thereby improving the cleaning effect on the three-phase separator.

[0017] 2. The preload of the elastic element will push the stop block and the long rod upward, causing the sealing plate to press tightly against the nozzle outlet to achieve a seal, thereby reducing the amount of dust in the tank from entering the housing through the nozzle and reducing the problem of dust adhering to the surface of the internal components.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1: Refer to Figure 1-6 A backwashable three-phase separator includes a tank 1, an exhaust assembly 2 connected to the top of the tank 1, a slag discharge assembly 3 connected to the bottom of the tank 1, a water inlet pipe 17 connected to the bottom of the outer side of the tank 1, two separation assemblies 4 arranged in the middle of the tank 1, forming a separation chamber between the two separation assemblies 4, a drain pipe 5 connected to one side of the tank 1, the water inlet end of the drain pipe 5 located in the separation chamber, a connecting pipe 6 placed on one side of the outer side of the tank 1, one end of the connecting pipe 6 passing through the tank 1 and connected to a shell 7, a rotating disk 8 connected to the bottom of the shell 7 through a sealed bearing, a plurality of nozzles 9 connected to the bottom of the rotating disk 8, and an adjustment mechanism provided in each of the nozzles 9.

[0027] Working Principle: The mixed liquid enters the tank 1 through the inlet pipe 17 and is separated by two-stage separation components 4. The lighter phase floats to the top and is discharged by the exhaust component 2, while the heavier solid phase settles to the bottom and is discharged by the slag discharge component 3. The purified liquid in between collects in the separation chamber and is discharged through the drain pipe 5. A small amount of solid particles in the liquid will be adsorbed on the surface of the lower separation component 4, and a trace amount of solid particles will be adsorbed on the surface of the upper separation component 4. Thus, during backwashing, high-pressure water enters the shell 7 through the connecting pipe 6, and the rotating disc 8 drives the nozzle 9 to rotate, causing the water to be sprayed at an angle onto the surface of the separation component 4 to break down the dirt. The slag is discharged by the slag discharge component 3. Compressed air enters through the exhaust component 2 to blow on the surface of the upper separation component 4, thereby cleaning both surfaces of the separation component 4 and improving the cleaning effect of the three-phase separator.

[0028] Example 2: In Example 1, dust and other particles inside the tank 1 enter the housing 7 through several nozzles 9, making the components inside the housing 7 easily disturbed. Based on Example 1, optimizations are made, referencing... Figure 1-6 The adjustment mechanism includes a fixing strip 10 fixed inside the nozzle 9, a sealing plate 11 placed at the bottom of the fixing strip 10, a long rod 12 connected to the top of the sealing plate 11, one end of the long rod 12 passing through the fixing strip 10 and connected to a stop block 13, and an elastic element 14 provided at the bottom of the stop block 13. One end of the elastic element 14 abuts against the fixing strip 10. Under normal conditions, the elastic element 14 drives the sealing plate 11 to move upward to close the water outlet of the nozzle 9.

[0029] Working principle: Under normal conditions, the preload of the elastic element 14 pushes the stop block 13 and the long rod 12 upward, causing the sealing plate 11 to press tightly against the nozzle 9 outlet to achieve a seal. This reduces the amount of dust in the tank 1 entering the housing 7 through the nozzle 9, and also reduces the problem of dust adhering to the surface of the internal components of the housing 7. When backwashing is started, high-pressure water enters the inner cavity of the nozzle 9. The fluid pressure acts on the sealing plate 11. When the water pressure overcomes the preload of the elastic element 14, the sealing plate 11 moves downward to open the nozzle, and water is sprayed out. This also avoids the situation where low pressure causes accidental opening and energy waste.

[0030] Example 3: In Example 1, after the high-pressure water flow enters the housing 7 through the connecting pipe 6, when the nozzles 9 clean the surface of the separation component 4, although the nozzles 9 can rotate with the rotating disk 8, the rotation amplitude is small, resulting in poor cleaning effect of the nozzles 9 on the surface of the separation component 4. Based on Examples 1-2, optimizations are made, referencing... Figure 1-6The shell 7 is disc-shaped. A rotating shaft 15 is connected inside the shell 7 via a sealed bearing. A vortex blade 16 is connected to the rotating shaft 15. The connecting pipe 6 is aligned with the vortex blade 16. One end of the rotating shaft 15 is connected to the rotating disk 8. The inlet height of the drain pipe 5 is located in the central area between the two separation components 4, and its inlet direction is perpendicular to the axis of the tank 1. The connecting pipe 6 is connected to an external flushing water source or a high-pressure fluid source. The water flows through the connecting pipe 6 and impacts the vortex blade 16, driving the rotating shaft 15 and the rotating disk 8 to rotate.

[0031] Working principle: High-pressure water flow tangentially impacts the vortex blades 16 from the connecting pipe 6, driving the vortex blades 16 to rotate the rotating shaft 15. The rotating shaft 15 drives the rotating disk 8 to rotate, and several nozzles 9 rotate together with the rotating disk 8. At the same time, the adjusting mechanism pushes open the sealing plate 11 under fluid pressure, so that the range of water flow sprayed onto the surface of the separation component 4 is increased, thereby improving the cleaning effect of the device on the surface of the separation component 4.

[0032] Example 4: An optimization based on Example 3, referencing... Figure 1-6 The nozzles 9 are evenly distributed along the circumference of the rotating disk 8, and their nozzles are tilted downwards, pointing towards the surface of one of the separation components 4. The tilted spray can concentrate the water flow impact force and reduce the situation where the water flow is dispersed and the cleaning force is insufficient; moreover, the water curtains of adjacent nozzles partially overlap during rotation, forming a continuous cleaning band, which improves the backwashing effect on the surface of the separation component 4.

[0033] Example 5: An optimization based on Example 1, with reference to... Figure 1-6 The elastic element 14 is set as a cylindrical spring and is sleeved on the fixing bar 10. The fixing bar 10 serves as the inner guide shaft of the spring, constraining the compression / extension path of the spring and preventing the spring from twisting and deforming during operation. The outer side of the long rod 12 is provided with a corrosion-resistant coating, which is a ceramic coating. This coating can reduce the corrosion of the substrate by corrosive media, reduce the failure of the rod body due to rust, thereby reducing the generation of corrosion products and reducing the frictional resistance between the long rod 12 and the guide hole of the fixing bar 10, ensuring that the long rod 12 slides smoothly up and down in the hole of the fixing bar 10.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
