Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and more specifically to a sewage multi-stage reverse osmosis treatment device for sewage treatment. Background Art

[0002] As the global water shortage problem becomes increasingly serious and environmental emission standards continue to improve, sewage multi-stage reverse osmosis treatment equipment has emerged and developed rapidly. This technology mainly targets the bottleneck problem that traditional sewage treatment processes are difficult to remove soluble salts, heavy metals and trace organic pollutants. It achieves deep sewage purification and resource reuse through multi-stage membrane separation technology.

[0003] Multi-stage reverse osmosis technology has become a core solution in the fields of high-salinity wastewater treatment and industrial wastewater reuse due to its desalination rate of more than 95% and water recovery rate of more than 80%, effectively alleviating the contradiction between water supply and demand and reducing the risk of environmental pollution.

[0004] However, the existing sewage multi-stage reverse osmosis treatment equipment has some problems when it is actually used;

[0005] 1. Lack of pre-treatment steps for sewage, resulting in large particles and other impurities in the sewage blocking the reverse osmosis membrane, thereby reducing the efficiency of sewage treatment and increasing the maintenance cost of multi-stage reverse osmosis treatment equipment;

[0006] 2. In order to overcome fluid resistance and ensure smooth flow during sewage treatment, pressurization is required. However, traditional pressurization technologies such as (centrifugal pumps, volumetric pumps), etc., cannot achieve the required ultra-high pressure (>10MPa) when treating difficult wastewater such as (high salt / toxic / difficult to degrade), which in turn affects the treatment quality of the wastewater.

[0050] Reference Fig.10 As shown, the angle of attack between the turbine blades on the surface of the turbine assembly 503 and the transmission shaft 501 is 8° to 12°.

[0051] The working principle of the present invention is as follows: first, when treating sewage, the water inlet pipe 11 is opened at this time, so that the sewage enters the treatment box inner cavity 101 opened in the sewage treatment box 1 through the water inlet pipe 11, and then the sewage enters to the top position of the coarse filter screen 801 opened in the centrifugal turntable 8, and at the same time, when the sewage is sent into the treatment box inner cavity 101, the servo motor 16 on the top of the fixed support plate 301 is turned on, so that the servo motor 16 drives the main gear 17 to rotate, and then the main gear 17 drives the gear on the surface of the boost gear set 4 to rotate, and then the boost gear set 4 rotates inside the protective box 3 so that the telescopic boost plug 18 is driven to rise and fall inside the boost chamber 204, and then the telescopic boost plug 18 rises and falls to drive the air inside the boost chamber 204 to be squeezed into the treatment The inner position of the box cavity 101 is then squeezed, and the squeezed air at this time pushes the blocking plug 1505 so that the one-way air intake valve core 15 blocks the air intake cavity 202 inside the mounting tube 201, and then the one-way exhaust core 19 is turned downward due to the obstruction of the arc-shaped baffle plate 205, and then the air inside the boost chamber 204 pushes the turbine assembly 503, and at this time the turbine assembly 503 drives the transmission shaft 501 and the transmission rod 502 to rotate, and then the transmission rod 502 rotates to drive the transmission crawler 6 so that the transmission crawler 6 drives the transmission gear set 7 to rotate, and then the rotation of the transmission gear set 7 drives the mutually meshing centrifugal turntable 8, and then the rotation of the centrifugal turntable 8 drives the coarse filter screen 801, so that the sewage on the top of the coarse filter screen 801 is thrown off;

[0052] Then the sewage on the top of the coarse filter screen 801 is swung and further pushed by the air. Then the sewage is accelerated by the pressure to be filtered through the coarse filter screen 801. Then the large particles of impurities filtered on the top of the coarse filter screen 801 are thrown around by the centrifugal force due to the swing of the coarse filter screen 801.

[0053] Then, when the telescopic boost plug 18 rises, negative pressure is formed inside the boost chamber 204, and then the one-way exhaust core 19 is reset due to the negative pressure, and at the same time, the blocking plug 1505 is flipped on the surface of the connecting block 1502 due to the negative pressure, so that the external air enters the air intake cavity 202 and the internal position of the boost chamber 204, and then when the telescopic boost plug 18 descends, the air is further squeezed into the sewage treatment tank 1 for continuous squeezing, and then the sewage filtered by the coarse filter screen 801 enters the first filter membrane 1301 through the circular through hole 2001 opened in the circular plate 20, and then enters the connecting guide pipe 14 after being filtered by the first filter membrane 1301, and then enters the second filter membrane 1302 through the connecting guide pipe 14, and then enters the third filter membrane 1303 and the fourth filter membrane 1304 through the second filter membrane 1302, and then the filtered sewage is discharged through the drain pipe 12 to complete the filtration.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
