Description

Technical Field

[0001] The present application relates to the technical field of sewage treatment, and in particular to a sewage treatment and reuse device. Background Art

[0002] Wastewater resource utilization refers to the use of advanced technical means to remove harmful substances in sewage, while recycling and utilizing water resources and useful substances in it to achieve wastewater reuse. This technology can not only alleviate the problem of water shortage, but also reduce environmental pollution and promote the development of a circular economy.

[0003] The existing technology still has the following problems:

[0004] 1. In the traditional sewage treatment method, a grille is set up to intercept and remove larger floating objects and suspended matter in the sewage, such as paper scraps and plastics. However, the grille is easily blocked by suspended matter after long-term use, so the grille needs to be dismantled and cleaned, which affects the sewage treatment efficiency. In addition, it is difficult to collect the suspended matter in a centralized manner when removing the suspended matter, so secondary collection is required, which wastes time.

[0005] 2. When treating sewage, it is necessary to use gravity sedimentation to remove inorganic particles with higher density in the sewage, such as sand and gravel, to prevent these substances from wearing out the equipment or affecting the treatment effect in subsequent treatment. The filter cylinder needs to be cleaned manually after long-term use to maintain normal use. At the same time, it is also necessary to remove the oil stains floating on the top layer of sewage, so it is necessary to set up a variety of pollution removal equipment for graded treatment, which makes the pollution removal process complicated. If the settled sand is not cleaned in time, the sand and gravel will continue to accumulate in the sand settling tank, which will cause the sludge layer at the bottom of the sedimentation tank to gradually thicken, thereby reducing the sedimentation efficiency and affecting the treatment effect of the wastewater.

The second water purification component 3 is located in the inner cavity of the first water storage tank 5, and the sewage enters the first water purification component 2 to remove larger floating objects and suspended objects, and is settled through the second water purification component 3 to remove sand and gravel particles in the sewage and oil stains suspended on the top layer of the sewage, and the first water purification component 2 and the second water purification component 3 can be self-cleaning, and the treated sewage flows from the first water storage tank 5 through the middle of the partition 4 into the inner cavity of the second water storage tank 6, and a water pump can be placed in the inner cavity of the second water storage tank 6 to pump out the water in the inner cavity of the second water storage tank 6 for subsequent treatment and subsequent reuse.

[0039] See also Figure 3 and Figure 4 As shown, the first water purification component 2 includes a clean water tank 21, and slag removal grooves 22 are opened on both sides of the clean water tank 21. A blocking block 23 is fixedly installed on the inner wall of the clean water tank 21. The upper surface of the blocking block 23 is flush with the bottom end of the slag removal groove 22. A grille frame 24 is arranged above the blocking block 23. The grille frame 24 and the clean water tank 21 are slidably connected. Pressure mechanisms 25 are arranged on the inner walls of both sides of the clean water tank 21. The bottom end of the clean water tank 21 is connected with a first water inlet pipe 26. The clean water tank 21 is fixedly connected to the sewage treatment tank 1. A collecting box 27 is slidably connected to the outer surface of the sewage treatment tank 1. The clean water tank 21 is located above the inner cavity of the collecting box 27. An alarm mechanism 28 is arranged at the bottom end of the collecting box 27. Wastewater flows into the inner cavity of the clean water tank 21 from the first water inlet pipe 26, and larger floating objects and suspended objects are blocked by the grille frame 24, thereby leaving the larger floating objects and suspended objects at the bottom end of the grille frame 24. When the larger floating objects and suspended objects are When the bottom end of the grille frame 24 is blocked, as the water flow of the first water inlet pipe 26 continues, the water flow will squeeze the grille frame 24, causing the grille frame 24 to move upward. At this time, the bottom end of the grille frame 24 is removed from the slag removal tank 22, allowing the water flow to flow to the slag removal tank 22. At the same time, the water flow impacts the bottom end of the grille frame 24 during the flow, taking away the larger floating objects and suspended matter at the bottom end of the grille frame 24. At this time, under the pressure of the pressure mechanism 25, the grille frame 24 returns to its original position, allowing water to pass through the grille frame 24, thereby achieving the effect of removing larger floating objects and suspended matter. At the same time, the collection box 27 is used to collect larger floating objects and suspended matter, and sewage accumulates in the inner cavity of the collection box 27 during the collection process. As the weight increases, the alarm mechanism 28 sounds an alarm to remind the staff to maintain the equipment to facilitate the normal operation of the equipment. The sewage on the clean water tank 21 enters the second water purification component 3 for further impurity removal.

When the grid frame 24 is blocked, the grid frame 24 squeezes the pressure plate 255 under the pressure of water. At this time, the connecting bar 254 rotates to drive the slide 253 to slide on the fixing rod 252, and the first spring 256 contracts to make the pressure plate 255 and the fixing frame 251 The spacing becomes smaller, so that the grid frame 24 moves upward, allowing the water flow to flow into the inner cavity of the collection box 27 in the slag removal trough 22. During the flowing process, the floating objects and suspended objects at the bottom of the grid frame 24 are flushed, so that the grid frame 24 has a self-cleaning effect. At the same time, under the elastic force of the first spring 256, the pressure plate 255 squeezes the grid frame 24 so that the grid frame 24 contacts the shielding block 23 again, and shields the slag removal trough 22 to prevent the water flow from entering the inner cavity of the collection box 27. Under the shielding of the grid frame 24, the floating objects and suspended objects in the sewage cannot pass through the top of the grid frame 24, thereby removing the floating objects and suspended objects in the sewage.

Parts between the limit grooves 288 are hollowed out, and the hollowed-out parts are smaller than the diameter of the limit grooves 288. The two ends of the adjusting rod 284 close to the inner wall of the first fixed block 281 are hollowed out.

When removing floating objects, When the floating objects and suspended objects at the bottom of the grille frame 24 are flushed, water and impurities are accumulated in the inner cavity of the collection box 27. Under the gravity of the water and impurities, the collection box 27 is driven to slide downward on the outer surface of the sewage treatment tank 1, so that the collection box 27 drives the pressure rod 282 to move downward in the inner cavity of the first fixed block 281, and the second spring 283 contracts under the pressure of the collection box 27. At this time, the extrusion ring 286 squeezes the button 2810, so that the speaker 2811 sounds an alarm, reminding the staff to maintain the sewage in the inner cavity of the collection box 27, which is convenient for the subsequent normal operation of the equipment. At the same time, it can also remind the grille frame 24 that when it is blocked for a long time and cannot be cleaned, and when the floating objects and suspended objects at the bottom of the grille frame 24 cannot be flushed, the collection box 27 is in a state of continuous weight gain. , and can also remind the staff to maintain and clean the grille frame 24.

[0045] In summary, the sewage enters the first water purification component 2 to remove larger floating objects and suspended objects, and is settled by the second water purification component 3 to remove sand and gravel particles in the sewage, as well as oil stains suspended on the top layer of the sewage. The first water purification component 2 and the second water purification component 3 can be self-cleaning. The treated sewage flows from the first water reservoir 5 through the middle of the partition 4 into the inner cavity of the second water reservoir 6. A water pump can be placed in the inner cavity of the second water reservoir 6 to pump out the water in the inner cavity of the second water reservoir 6 for subsequent treatment and For subsequent reuse, the wastewater flows from the first water inlet pipe 26 into the inner cavity of the clean water tank 21, and the larger floating objects and suspended objects are blocked by the grid frame 24, so that the larger floating objects and suspended objects are left at the bottom of the grid frame 24. When the larger floating objects and suspended objects block the bottom of the grid frame 24, as the water flow of the first water inlet pipe 26 continues, the water flow will squeeze the grid frame 24, causing the grid frame 24 to move upward. At this time, the bottom end of the grid frame 24 is removed from the slag removal tank 22, so that the water The water flows to the slag removal tank 22 for circulation. At the same time, the water flow impacts the bottom end of the grid frame 24 during the flow, and takes away the larger floating objects and suspended objects at the bottom end of the grid frame 24. At this time, under the pressure of the pressure mechanism 25, the grid frame 24 returns to its original position, allowing the water to pass through the grid frame 24, thereby achieving the effect of removing larger floating objects and suspended objects. At the same time, the collecting box 27 is used to collect larger floating objects and suspended objects, and sewage accumulates in the inner cavity of the collecting box 27 during the collection process. As the weight increases, the alarm mechanism 28 sounds an alarm to remind the staff to maintain the equipment. The sewage enters the inner cavity of the filter screen cylinder 32 from the second water inlet pipe 34. The decontamination mechanism 35 rotates to clean the filter screen cylinder 32, and at the same time, the sand and gravel can be settled, and the oil stains on the top layer of the sewage can be skimmed off. The sand and gravel enter the dust removal mechanism 37 through the sedimentation hopper 33 for centralized cleaning. The water treated in the second water purification component 3 enters the second water storage tank 6 from the partition 4, achieving the sewage decontamination effect, which is convenient for subsequent reuse.
