Description

Technical Field

[0001] The invention belongs to the technical field of wastewater treatment, in particular to a wastewater treatment device for high-altitude engineering construction. Background Art

[0002] Construction projects in high-altitude areas often generate large amounts of wastewater, often containing silt, impurities, or chemicals. This wastewater primarily originates from concrete mixing, equipment cleaning, washing, rainfall at the construction site, and groundwater infiltration. Especially in construction environments involving large-scale land evacuation, wastewater can contain significant amounts of silt and pollutants, which not only impacts the environment but can also damage construction equipment. The presence of large amounts of solid particles in wastewater can cause turbidity, leading to the use of sedimentation tanks for solid-liquid separation. Sedimentation tanks utilize the principle of static settling, allowing solid particles to settle over a long period of time, resulting in stratification and removal of silt and impurities. However, sedimentation tanks typically have slow treatment efficiency and can still retain some fine solid particles, requiring a long time to separate, making rapid wastewater recycling and reuse difficult. Furthermore, wastewater pumping stations are often used to transport wastewater, but the presence of solid particles in the wastewater can cause wear on the pumps, shortening the service life of the pumping stations.

[0003] A Chinese patent application CN117658268B discloses a micro-powered flotation wastewater treatment device for engineering construction. Specifically, the device relates to a micro-powered flotation wastewater treatment device for engineering construction. Wastewater can be coarsely filtered and then enter a water storage chamber. Dissolved oxygen bubbles are injected into the wastewater through a dissolved oxygen bubble injection component, so that the bubbles adhere to solid particles and pollutants in the wastewater and drive them to float to form a scum layer. When the spiral collection net rotates, the scum on the surface of the wastewater is collected inside. The scum is separated from the wastewater surface and, as the spiral collection net rotates, is rolled to the strip holes of the central shaft tube. The scum enters the central shaft tube through the strip holes of the central shaft tube and is discharged from the output end of the central shaft tube, completing the rapid solid-water separation treatment of the engineering wastewater and realizing the recycling and reuse of the wastewater.

[0004] However, the above technologies often have the following defects: the existing technology collects scum while rotating by setting a central axis tube and a spiral collection net cylinder. Since the scum is usually in the form of foam, during the collection process, some of the scum easily adheres to the inner wall of the spiral collection net cylinder, resulting in incomplete discharge of the scum, thereby affecting the efficiency and effect of wastewater treatment.

[0005] To this end, the present invention provides a wastewater treatment device for high-altitude engineering construction. Summary of the Invention

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] Example 1: Figures 1 to 6 As shown, a high-altitude engineering construction wastewater treatment device according to an embodiment of the present invention includes: A treatment pool 1, wherein a sliding cavity 12 is provided inside the top of the treatment pool 1, and a lifting frame 4 is sealed and slidably installed in the sliding cavity 12; An aeration device 3 is provided at the bottom of the treatment tank 1 and includes a main pipe, a plurality of branch pipes are fixed to the side of the main pipe, a plurality of aeration nozzles are evenly distributed on the branch pipes, and the main pipe is connected to an external air source through an air inlet pipe; A filter tank 5 is provided on the top of the lifting frame 4. The sewage entering the treatment tank 1 is initially filtered through the filter tank 5. The filter tank 5 includes a bottom plate 8 and an upper frame structure. The bottom plate 8 is fixedly connected to the lifting frame 4. A filter screen 9 is installed in the middle of the bottom plate 8. A drive assembly includes a hydraulic cylinder 13 disposed inside the sliding cavity 12. Four hydraulic cylinders 13 are symmetrically distributed at the corners of the screw rod at the bottom of the lifting frame 4. The hydraulic cylinders 13 are used to control the lifting frame 4 to rise or fall. A collecting tank 2, wherein the collecting tank 2 is fixed around the side wall of the treatment tank 1; During operation, a water inlet pipe is fixed to the side of the filter tank 5, which is connected to the pump body through a hose. The sewage in the sedimentation tank is pumped into the filter tank 5 through the pump body. The filter screen 9 performs preliminary filtration on the sewage to remove larger impurities in the sewage. The filtered sewage flows from the filter tank 5 into the treatment tank 1 below until the water surface of the wastewater in the treatment tank 1 approaches the top of the lifting frame 4. Then the aeration device 3 is started, and the gas is introduced into the main pipe through the connecting pipe 32. The air bubbles are then transported to the bottom of the wastewater through the branch pipe and the aeration nozzle. The adhesion of the bubbles is utilized. These bubbles can attach to solid particles and pollutants in the wastewater. Due to the buoyancy of the bubbles, the bubbles carrying pollutants and solid particles will quickly rise to the surface of the wastewater to form a layer of scum; then the drive component is started to control the telescopic rod of the hydraulic cylinder 13 to contract, thereby driving the lifting frame 4 to move downward. At this time, the water level in the treatment pool 1 is higher than the lifting frame 4, and the wastewater overflows from the top of the lifting frame 4, while carrying the scum on the water surface and directly discharged to the surroundings. The discharged scum is collected by the collection tank 2, which can quickly clean the scum and improve the efficiency and effect of wastewater treatment.

[0024] The fixed plate 11 is provided with a U-shaped plate 10 on the side, and the fixed plate 11 and the U-shaped plate 10 form a closed frame structure. A sliding hole is opened in the middle of the side wall of the lifting frame 4, and a push rod 31 is slidably installed in the middle of the sliding hole. The bottom end of the push rod 31 is fixed to the bottom of the sliding cavity 12, and the top end of the push rod 31 is fixed to the bottom of the U-shaped plate 10; during operation, when the lifting frame 4 descends, the U-shaped plate 10 is lifted up by the push rod 31, so that the bottom of the U-shaped plate 10 is separated from the bottom plate 8. At this time, part of the wastewater in the treatment pool 1 flows upward from the bottom of the filter screen 9, and the wastewater is used to backwash the filter screen 9, thereby cleaning the impurities on the top of the filter screen 9, and the impurities are discharged from the gap between the U-shaped plate 10 and the bottom plate 8, and are collected by the collecting tank 2, which can clean the surface of the filter screen 9 and maintain good filtering performance.

[0025] An isolation shell 14 is fixed below the bottom plate 8, and the bottom of the isolation shell 14 is set to be inclined; when working, the bottom of the isolation shell 14 is open, which does not affect the flow of wastewater from the filter tank 5 into the treatment tank 1. The bottom of the isolation shell 14 is set to be inclined so as to guide the scum to move to the side of the isolation shell 14, so that the scum is not easy to contact the bottom of the filter screen 9, thereby facilitating subsequent scum cleaning.

[0026] An air duct 17 is fixed in the middle of the isolation shell 14, and one end of the air duct 17 is connected to the cavity in the middle of the fixed plate 11 through the air inlet hole 18 provided on the bottom plate 8, and the other end of the air duct 17 is connected to the sliding cavity 12 through the air channel 16 provided in the middle of the lifting frame 4. The sliding cavity 12 is connected to the air inlet pipe of the aeration device 3 through the connecting pipe 32, and the outer wall of the fixed plate 11 is evenly distributed with multiple nozzles 20; during operation, during the aeration process, the air from the connecting pipe 32 is introduced into the interior of the sliding cavity 12 through the air duct 17, and then the air enters the middle cavity of the fixed plate 11 through the air channel 16, the air duct 17 and the air inlet hole 18, and is finally ejected from the nozzle 20. The ejected airflow prevents scum from adhering to the outer wall of the filter tank 5, thereby facilitating the subsequent cleaning of the scum.

[0027] A partition 19 is slidably installed in the middle of the fixed plate 11, and the partition 19 divides the middle cavity of the fixed plate 11 into a left chamber and a right chamber. The outer wall of the left chamber is evenly distributed with multiple nozzles 21, and the nozzles 1 20 are evenly distributed on the outer wall of the right chamber. The top of the partition 19 is fixedly connected to the U-shaped plate 10 through the connecting plate 15, and the air inlet 18 is set below the right chamber; when working, in the process of treating the wastewater in the treatment tank 1, air enters the right chamber through the air inlet 18, and at this time only the nozzle 1 20 sprays out Airflow. When it is necessary to discharge the scum, the lifting frame 4 is controlled to descend. At this time, the U-shaped plate 10 is pushed upward relatively by the push rod 31, and then the partition 19 is synchronously driven upward by the connecting plate 15, so that the left chamber and the right chamber are connected. At this time, the nozzle 1 20 and the nozzle 2 21 spray airflow at the same time. The airflow sprayed by the nozzle 1 20 prevents the scum from adhering to the outer wall of the filter tank 5, and the airflow sprayed by the nozzle 2 21 pushes the impurities above the filter screen 9 to be quickly discharged outward along with the upwelling wastewater, so as to quickly clean the impurities above the filter screen 9.

[0028] A square sleeve 23 is fixed to the outside of the air guide tube 17, and a plurality of magnetic blocks 24 are arranged at intervals on the sleeve 23. A movable platform 25 is slidingly sleeved on the outside of the sleeve 23. A movable cavity is opened on the side opposite to the filter screen 9, and a movable block 27 is arranged inside the movable cavity. A spring 26 for resetting the movable block 27 is fixed inside the movable cavity. A pull rope 22 is fixed to the side of the movable platform 25. The end of the pull rope 22 away from the movable platform 25 is fixedly connected to the bottom end of the partition 19. A spring 26 for resetting the movable block 27 is fixed between the movable platform 25 and the isolation shell 14. Spring 2 28; when working, when the partition 19 moves up, the movable platform 25 is pulled by the pull rope 22 to move horizontally along the sleeve 23. At this time, the spring 28 is stretched. When the movable platform 25 is aligned with the magnetic block 24, the movable block 27 is attracted to move downward by the magnetic block 24. At this time, the spring 1 26 is compressed. When the movable platform 25 and the magnetic block 24 are misaligned, the movable block 27 is pushed upward by the spring 1 26 and hits the bottom of the filter 1 9. The vibration generated separates the impurities from the filter 1 9, so as to clean the impurities attached to the surface of the filter 1 9 that are difficult to clean, thereby improving the impurity cleaning efficiency.

[0029] A filter tank 2 6 is installed on the side of the collection tank 2 away from the filter tank 5, and a filter screen 2 33 is installed in the middle of the filter tank 2 6; when working, the scum discharged from the treatment pool 1 and the impurities discharged from the filter tank 5 are collected by the collection tank 2, and the discharged part of the treated sewage flushes the collection tank 2, and the scum and impurities are flushed into the filter tank 2 6 for collection.

[0030] The bottom plate 8 of the collecting tank 1 2 is gradually lowered from the filtering tank 1 5 to the filtering tank 2 6; during operation, by setting the bottom plate 8 of the collecting tank 1 2 to an inclined shape, the scum and impurities are quickly gathered in the filtering tank 2 6, thereby improving the collection efficiency.

[0031] A collecting tank 2 7 is provided below the filtering tank 2 6 ; when working, scum and impurities are filtered out through the filter screen 2 33 , and the waste water filtered out from the filtering tank 2 6 is collected through the collecting tank 2 7 to avoid wasting water resources.

[0032] Example 2: Figure 7As shown, in contrast to Example 1, another embodiment of the present invention is as follows: a notch is provided on one side of the collecting tank 2 away from the filter tank 5, and slots 29 are symmetrically provided on both sides of the notch. One side of the filter tank 2 6 is open, and L-shaped limiting rods 30 are symmetrically fixed on both sides of the opening of the filter tank 2 6, and the limiting rods 30 and the slots 29 are plugged into each other; during operation, the limiting rods 30 are inserted into the slots 29 to quickly install the filter tank 2 6, and the limiting rods 30 and the slots 29 are adapted to make the filter tank 2 6 stably installed on the outside of the collecting tank 2, and make the opening of the filter tank 2 6 aligned with the notch of the collecting tank 2, and the scum and impurities in the collecting tank 2 can flow into the filter tank 2 6 as the sewage passes through the opening and be collected, and then the limiting rod 30 is removed from the slots 29, and the filter tank 2 6 can be quickly disassembled, which is convenient for cleaning the collected scum and impurities.

[0033] Working principle: The sewage in the sedimentation tank is pumped into the filter tank 5 through the pump body, and the filter screen 9 performs preliminary filtration on the sewage to remove larger impurities in the sewage. The filtered sewage flows from the filter tank 5 into the treatment tank 1 below until the water surface of the wastewater in the treatment tank 1 approaches the top of the lifting frame 4. Then the aeration device 3 is started, and the gas is introduced into the main pipe through the connecting pipe 32. Then, the air bubbles are transported to the bottom of the wastewater through the branch pipe and the aeration nozzle. By virtue of the adhesion of the bubbles, these bubbles can adhere to the solid particles and pollutants in the wastewater. Due to the buoyancy of the bubbles, the bubbles carrying pollutants and solid particles will quickly rise to the surface of the wastewater to form a layer of scum; then the driving component is started to control the telescopic rod of the hydraulic cylinder 13 to retract, thereby driving the lifting frame 4 to move downward. At this time, the water level in the treatment tank 1 is higher than the lifting frame 4, and the wastewater overflows from the top of the lifting frame 4, carrying the scum on the water surface to be discharged to the surroundings, and the discharged scum is collected by the collecting tank 2, which can quickly clean the scum. When the lifting frame 4 descends, the U-shaped plate 10 is lifted up by the push rod 31, so that the bottom of the U-shaped plate 10 is separated from the bottom plate 8. At this time, part of the wastewater in the treatment tank 1 flows upward from the bottom of the filter screen 9, and the wastewater is used to backwash the filter screen 9, thereby cleaning the impurities on the top of the filter screen 9. The impurities are discharged from the gap between the U-shaped plate 10 and the bottom plate 8 and are collected by the collecting tank 2, which can clean the surface of the filter screen 9 and maintain good filtering performance. During the aeration process, when the wastewater in the treatment tank 1 is being treated, the air from the connecting pipe 32 is introduced into the sliding cavity 12 through the air guide pipe 17, and then the air enters the right chamber through the air duct 16, the air guide pipe 17 and the air inlet 18. At this time, only the nozzle 120 sprays air, and the air flow sprayed by the nozzle 120 prevents the scum from adhering to the outer wall of the filter tank 5; when the scum needs to be discharged, the lifting frame 4 is controlled to descend, and at this time the U-shaped plate 10 is pushed upward by the push rod 31, and then the partition 19 is synchronously driven upward by the connecting plate 15, so that the left chamber and the right chamber are connected. At this time, the nozzle 120 and the nozzle 2 21 spray air at the same time, and the air flow sprayed by the nozzle 2 21 pushes the impurities above the filter screen 9 to be quickly discharged outward along with the upwelling wastewater, so as to quickly clean the impurities above the filter screen 9; When the partition 19 moves upward, the movable platform 25 is pulled by the pull rope 22 to move horizontally along the sleeve 23. At this time, the spring 28 is stretched. When the movable platform 25 is aligned with the magnetic block 24, the movable block 27 is attracted to move downward by the magnetic block 24. At this time, the spring 1 26 is compressed. When the movable platform 25 and the magnetic block 24 are misaligned, the movable block 27 is pushed upward by the spring 1 26 and hits the bottom of the filter 1 9. The vibration generated separates the impurities from the filter 1 9, so as to clean the impurities attached to the surface of the filter 1 9 that are difficult to clean, thereby improving the impurity cleaning efficiency.
