Description

Technical Field

[0001] The utility model relates to the technical field of ultrafiltration tanks, in particular to a regenerated water immersed ultrafiltration tank. Background Art

[0002] The reclaimed water submerged ultrafiltration tank is an advanced water treatment facility, which is mainly used to deeply filter the reclaimed water after preliminary treatment to remove impurities such as tiny particles, bacteria, viruses, etc. in the water, so as to achieve higher water quality standards. This technology combines the concepts of submerged ultrafiltration and reclaimed water treatment, realizing the efficient utilization and high-quality regeneration of water resources. The working principle of the reclaimed water submerged ultrafiltration tank is mainly based on the filtering effect of the ultrafiltration membrane. When the reclaimed water enters the ultrafiltration tank, the water is guided to the ultrafiltration membrane assembly immersed in the tank by pressure or gravity. These ultrafiltration membranes have very small pore sizes, usually between 0.01 and 0.1 microns, which can effectively intercept impurities such as suspended matter, colloids, bacteria, viruses, etc. in the water. Water molecules and useful substances dissolved in water can pass through the membrane pores, thereby achieving solid-liquid separation.

[0003] When the existing ultrafiltration pool is in use, the ultrafiltration membrane will be blocked due to the long-term use of the ultrafiltration membrane to filter impurities in the water. Once the ultrafiltration membrane is blocked, its filtration performance will be affected, thereby reducing the treatment effect of the ultrafiltration membrane, which is inconvenient for users to use. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Embodiment 1

[0024] See also Figures 1 to 5 A regenerated water immersed ultrafiltration tank comprises an ultrafiltration tank body 1, the top of one side of the ultrafiltration tank body 1 is connected with an inlet pipe 2, the bottom of one side of the ultrafiltration tank body 1 is connected with an outlet pipe 3, the interior of the ultrafiltration tank body 1 is fixedly connected with a mounting frame 4, the inner side of the mounting frame 4 is fixedly connected with an ultrafiltration membrane 5, the ultrafiltration membrane 5 is arranged in a flat plate shape, the inner side of the mounting frame 4 is fixedly connected with an opening and closing plate 6 located at the bottom of the ultrafiltration membrane 5, both sides between the ultrafiltration membrane 5 and the opening and closing plate 6 are provided with aeration pipes 7, the number of aeration pipes 7 is several, and the several aeration pipes 7 are equidistantly distributed, one end of the aeration pipe 7 passes through the outer side of the ultrafiltration tank body 1 and is connected with an aeration component, the aeration component is used to input gas into the aeration pipe 7, the inner side of the opening and closing plate 6 is rotatably connected with a closing mechanism, and the closing mechanism can close the gap in the opening and closing plate 6.

[0025] The closing mechanism includes a blade 901, one end of which is fixedly connected to a first fixed column 902, and the outer side of the first fixed column 902 is fixedly connected to two first pulleys 903. There are several blades 901, and the several blades 901 are equidistantly distributed. The first pulley 903 can connect the several blades 901 to each other through a belt, so that when one blade 901 rotates, all subsequent blades 901 can be driven to rotate successively in a chain reaction.

[0026] A second pulley 904 is rotatably connected to the inner side of one of the aeration tubes 7, and a wind wheel 905 is fixedly connected to one side of the second pulley 904. The position of the wind wheel 905 in the aeration tube 7 can determine whether it rotates clockwise or counterclockwise. One side of the wind wheel 905 is rotatably connected to the inner wall of the aeration tube 7, and the second pulley 904 is connected to the first pulley 903 via a belt drive.

[0027] The working principle of this embodiment is as follows: after the ultrafiltration membrane 5 has been in use for a long time, there are many dust and impurities inside it. At this time, gas is input into the aeration pipe 7 through the aeration component, and the gas in the aeration pipe 7 drives the wind wheel 905 to rotate. After the wind wheel 905 rotates, it drives the second pulley 904 to rotate. The second pulley 904 drives the first pulley 903 to rotate through the belt. After the first pulley 903 rotates, it drives several blades 901 to follow the synchronous rotation through the belt. In the initial state, the blade 901 is in an upright state. At this time, the opening slot 12 can be passed through Water flow, when the blade 901 rotates, the blade 901 closes the opening and closing plate 6, and a sealed space is formed between the opening and closing plate 6 and the ultrafiltration membrane 5. Subsequently, the gas discharged from the aeration pipe 7 cannot be discharged downward through the closed opening and closing plate 6, and can only be discharged upward through the ultrafiltration membrane 5. When the gas impacts the ultrafiltration membrane 5 upward, the ultrafiltration membrane 5 can be backwashed, so that the impurities accumulated in the ultrafiltration membrane 5 are blown out. After the impurities are blown out, the filtering effect of the ultrafiltration membrane 5 can be restored, and the filtering effect will not become weaker and weaker, further ensuring the practicality of the ultrafiltration pool.

[0028] Embodiment 2

[0029] This embodiment is an improvement made on the basis of the first embodiment. For details, please refer to Figures 1 to 5 The other end of the blade 901 is fixedly connected to a second fixing column 10 , and one side of the second fixing column 10 is rotatably connected to the inner wall of the opening and closing plate 6 .

[0030] A spring 11 is fixedly connected to the outer side of the second fixing column 10 , and one end of the spring 11 is fixedly connected to the inner wall of the opening and closing plate 6 .

[0031] An opening groove 12 is provided inside the opening and closing plate 6, and the opening groove 12 is clearance-matched with the leaf plate 901. In the initial state, the elastic force of the spring 11 will drive the leaf plate 901 to be vertical to the opening and closing plate 6 inside the opening and closing plate 6 through the second fixed column 10, so that the opening groove 12 inside the leaf plate 901 is opened.

[0032] By setting the second fixed column 10 and the spring 11, when the aeration pipe 7 discharges gas, it will drive the blade 901 to rotate and close the opening slot 12. When the aeration pipe 7 does not discharge gas, the elastic force of the spring 11 will drive the second fixed column 10 to restore the blade 901 to its initial state. At this time, the opening slot 12 is opened again, and the water filtered by the ultrafiltration membrane 5 will continue to flow downward.

[0033] Grooves 13 are formed on both sides of the blade 901 . A convex plate 14 is fixedly connected to the inner side of the open groove 12 . A sealing gasket 15 is fixedly connected to one side of the groove 13 . The sealing gasket 15 contacts the convex plate 14 .

[0034] By providing the groove 13, the convex plate 14 and the sealing gasket 15, when the blade 901 closes the open groove 12, the convex plate 14, the groove 13 and the sealing gasket 15 can play a sealing effect, thereby preventing the gas discharged from the aeration pipe 7 from being discharged downward through the gap between the blade 901 and the open groove 12 to affect the backwashing effect, thereby further improving the backwashing effect of the ultrafiltration membrane 5.

[0035] The aeration assembly includes a shunt pipe 801 , one side of which is connected to an air pump 802 , and the air pump 802 is fixedly connected to the ultrafiltration tank body 1 .

[0036] By setting up an aeration component and starting the air pump 802, the air pump 802 inputs gas into the shunt pipe 801, and the gas enters between the ultrafiltration membrane 5 and the opening and closing plate 6 through the aeration pipe 7, so that the impurities in the ultrafiltration membrane 5 can be backwashed and discharged.
