Description

Technical Field

[0001] The present invention relates to the technical field of wastewater treatment, and more specifically, to an intelligent wastewater treatment device for an airport. Background Art

[0002] When an airport treats wastewater, it generally needs to carry out processes such as interception, sedimentation, precipitation, biological treatment, deep treatment and disinfection. In the sedimentation process, relatively large sediment will settle to the bottom of the pool, so a scraper is needed to remove the sediment settled at the bottom of the pool. However, when the existing scraper uses a scraper to move the sediment settled at the bottom of the pool, part of the sediment will be lifted up, causing part of the sediment settled at the bottom of the pool to be redispersed in the wastewater, thereby reducing the wastewater sedimentation efficiency. Summary of the invention

[0003] In order to overcome the disadvantage that when a scraper uses a scraper to stir the silt settled at the bottom of a pool, part of the silt will be lifted up, resulting in a decrease in the wastewater sedimentation efficiency, the present invention provides an intelligent airport wastewater treatment device.

[0004] The technical solution is as follows: an intelligent airport wastewater treatment equipment, comprising a box body and a pipe; at least four pipes are passed through the box body; a main controller is arranged on the box body; a cavity is opened on the box body, and an intelligent water level monitor is arranged in the cavity, and the intelligent water level monitor is connected to the main controller through a wireless signal; a cavity is opened on the box body, and the cavity is located on the lower side of the cavity, and the cavity is connected to the cavity; the lower port of each pipe is located in the cavity; it also includes a foam absorber, a water pumping box, a scraper, a conveying assembly and a driving assembly; a foam absorber is installed on the box body; a water pumping box is installed on the box body; a conveying assembly is connected to the box body, and the conveying assembly is used to convey wastewater to the cavity; a driving assembly is connected to the box body; at least six scrapers are connected to the driving assembly, and the scrapers are in contact with the box body; the driving assembly is used to drive the scrapers to perform circumferential rotation; the cross-section of the scraper is hook-shaped.

[0005] Furthermore, the conveying assembly includes box body 2 and pipe 2; box body 2 is fixedly connected to box body 1; pipe 2 is connected to box body 2, and pipe 2 passes through box body 1; box body 2 is provided with at least three circular holes.

[0006] Furthermore, the driving assembly includes a motor, a round rod, a sprocket and a chain; the motor is fixedly connected to the box body; at least four round rods are rotatably connected to the box body; each round rod is fixedly connected to at least two sprockets; at least two chains are arranged on the inner side of the box body, the chains are meshed with the corresponding sprockets, and the chains are fixedly connected to the corresponding scrapers.

[0007] Furthermore, a filter screen 1 is included; an opening is formed at the curved portion of each scraper, and a filter screen 1 is fixedly connected to the opening of each scraper.

[0008] Furthermore, it also includes a shielding component; the shielding component is connected to the scraper; the shielding component includes a connecting block and a curved plate; at least two connecting blocks are fixedly connected to each scraper; an curved plate is rotatably connected between each front and rear adjacent connecting blocks, and the curved plate is in contact with the corresponding scraper.

[0009] Furthermore, the arc-shaped plate has elasticity.

[0010] Furthermore, at least two grooves are formed on the box body, and the grooves match the arc-shaped plate.

[0011] Furthermore, a counterweight bar is included; each arc-shaped plate is fixedly connected with a counterweight bar.

[0012] Furthermore, it also includes a filter screen 2; each arc plate has an opening, and a filter screen 2 is fixedly connected to the opening of each arc plate.

[0013] Furthermore, the sprocket and the chain are both made of rust-proof material.

[0014] The present invention has the following advantages:

[0015] 1. The cross section of the scraper is in the shape of a hook, so that when the scraper moves the sediment settled at the inner bottom of the cavity to the right, the straight plate part of the scraper can block and limit the sediment to avoid lifting the sediment, thereby avoiding the problem of reduced wastewater sedimentation efficiency caused by the lifting of sediment during the mud scraping process of the existing equipment. At the same time, the scraper with a hook-shaped cross section can also intercept the floating foam through its straight plate part to prevent the floating foam from sinking back into the depth of the wastewater to ensure the efficiency of floating foam suction. At the same time, when the scraper moves the sediment to the left, the wastewater flows through the opening of the scraper corresponding to the filter screen, thereby avoiding the problem of reduced sediment scraping efficiency caused by the scraper moving the wastewater to the left;

[0016] Second, the opening on the scraper corresponding to the filter screen 1 is covered by the curved plate 1, so that the scraper and the curved plate together push the foam to move to the right, thus avoiding the problem of reduced foam removal efficiency caused by the alignment of the foam on the wastewater surface with the filter screen 1;

[0017] 3. The arc plate 1 used for moving the floating foam can also be used to push the mud and sand gathered in the curved part of the scraper into the cavity 2, which greatly reduces the residual amount of mud and sand in the curved part of the scraper, which is beneficial to improving the efficiency of mud and sand removal. At the same time, by providing a groove on the box body 1, it is avoided that the rebound speed of the arc plate 1 is slowed down due to the existence of friction, thereby avoiding reducing the effect of the arc plate 1 rebounding to push the mud and sand. At the same time, the wastewater between the arc plate 1 and the scraper can flow out from the opening of the filter screen 2 on the arc plate 1, so that the scraper can be fully squeezed and deformed to ensure the effect of rebound pushing the mud and sand. At the same time, the weight bar is used to increase the gravity on the end of the arc plate 1, thereby avoiding the problem of slow rotation caused by the resistance of the arc plate 1 to the wastewater, which is beneficial to improving efficiency, thereby avoiding the problem of reduced floating foam cleaning efficiency caused by the slow rotation of the arc plate 1.

[0028] Example 1

[0029] An intelligent airport wastewater treatment device, such as Figure 1-Figure 7 As shown, it includes a box body 1 and a pipe 2; four pipes 2 are passed through the box body 1, and the pipes 2 are set to be made of alloy material; a main controller is set on the box body 1; a cavity 91 is opened on the box body 1, and an intelligent water level monitor is set in the cavity 91, and the intelligent water level monitor is connected to the main controller through a wireless signal; a cavity 2 92 is opened on the box body 1, and the cavity 2 92 is located at the lower side of the cavity 1 91, and the cavity 1 91 is connected to the cavity 2 92; the lower port of each pipe 2 is Located in cavity 1 92; also includes a foam absorber 3, a water pumping box 4, a scraper 5, a conveying assembly and a driving assembly; the foam absorber 3 is installed on the box body 1; the water pumping box 4 is installed on the box body 1; the box body 1 is connected to the conveying assembly, and the conveying assembly is used to transport wastewater to cavity 1 91; the box body 1 is connected to the driving assembly; six scrapers 5 are connected to the driving assembly, and the scrapers 5 are in contact with the box body 1; the driving assembly is used to drive the scrapers 5 to perform circumferential rotational motion; the cross-section of the scraper 5 is hook-shaped.

[0030] The conveying assembly includes a box body 201 and a pipe 202; the box body 201 is bolted to the box body 1; the box body 201 is connected to the pipe 202, and the pipe 202 passes through the box body 1; three circular holes 94 are opened on the box body 201, and wastewater is transported to the box body 201 through the pipe 202, and the wastewater flows into the cavity 1 91 from the circular holes 94.

[0031] The driving assembly includes a motor 203, a round rod 204, a sprocket 205 and a chain 206; the motor 203 is bolted to the box body 1; four round rods 204 are rotatably connected to the box body 1; two sprockets 205 are fixed to each round rod 204; two chains 206 are arranged on the inner side of the box body 1, the chains 206 are meshed with the corresponding sprockets 205, and the chains 206 are bolted to the corresponding scrapers 5.

[0032] It also includes a filter screen 207; the curved portion of each scraper 5 is provided with an opening for waste water to pass through, and a filter screen 207 is fixedly connected to the opening of each scraper 5, through which the sediment is intercepted.

[0033] First, manually connect the external water inlet pipe to the second pipe 202, connect the external water outlet pipe to the pumping box 4, connect the external sewage suction pipe to the pipe 1 2, and then transport the airport wastewater to the second pipe 202 through the external water inlet pipe. The wastewater flows into the inner side of the box 2 201 through the pipe 202, and then flows into the cavity 1 91 from the circular hole 94. The wastewater level is monitored in real time by the intelligent water level monitor in the cavity 1 91. When the wastewater in the cavity 1 91 overflows the half position of the upper scraper 5, the intelligent water level monitor transmits the signal to the main controller, and the main controller controls the pumping box 4 to start absorbing water from the cavity 1 91, so that the wastewater in the cavity 1 91 flows into the external water outlet pipe through the pumping box 4. At the same time, the main controller controls the external sewage suction pipe to pump water from the pipe 1 2. Suction operation is performed to make the wastewater in cavity 1 92 flow into the external sewage suction pipe through pipe 1 2, and the amount of wastewater flowing out and flowing into cavity 1 91 is controlled by the main controller, so that the wastewater liquid level in cavity 1 91 always overflows the half position of the scraper 5. In this process, since the box 201 for discharging wastewater is far away from the pumping box 4 for discharging wastewater, the wastewater carrying sediment flows from box 201 into cavity 1 91 and then enters the sedimentation operation, so that the sediment is close to being completed when it flows to the half position of cavity 1 91. When the intelligent water level monitor transmits the signal to the main controller, the main controller also starts the motor 203 and the foam absorber 3, the motor 203 drives the round rod 204 to rotate, the round rod 204 drives the sprocket 205 to rotate, and the sprocket 205 drives the chain The chain 206 moves, and the scraper 5 is driven by the chain 206 to rotate in a circumferential direction. During this process, the scraper 5 first moves to the left along the lower side of the cavity 1 91. When the scraper 5 moves to the cavity 2 92, it moves upward, then moves to the right along the wastewater surface, and then moves downward back to its original position. When the scraper 5 moves along the lower side of the cavity 1 91, it will push the mud and sand settled at the bottom of the inner side of the cavity 1 91 to move to the right. In the process of pushing the mud and sand, the mud and sand are gradually accumulated on the left side of the curved part of the scraper 5. The straight plate part of the scraper 5 is used to block and limit the mud and sand to avoid lifting the mud and sand. When the scraper 5 moves to the top of the cavity 2 92, the mud and sand accumulated on the left side of the curved part of the scraper 5 will fall into the cavity 2 92, and then be sucked away by the pipe 1 2 to complete the mud scraping and cleaning operation. When the scraper 5 moves rightward along the wastewater surface, the scraper 5 moves the floating foam on the liquid surface to the right, and moves the floating foam to the left side of the foam absorber 3, and then the floating foam is sucked out by the foam absorber 3, and then the wastewater after sedimentation and foam removal is sucked into the external water outlet pipe through the water pumping box 4 located on the upper right side of the cavity 91, and the external water outlet pipe transports it to the next equipment for subsequent treatment. When in use, because the cross-section of the scraper 5 is in the shape of a curved hook, when the scraper 5 moves the mud and sand settled at the bottom of the inner side of the cavity 91 to the right, the straight plate part of the scraper 5 can be used to block and limit the mud and sand to avoid lifting the mud and sand, thereby avoiding the problem of reduced wastewater sedimentation efficiency caused by lifting the mud and sand during the scraping process of the existing equipment. At the same time, through the cooperation of the intelligent water level monitor and the main controller,It realizes intelligent control of pipeline 1 2, foam absorber 3, water pumping box 4, and scraper 5 operation, treats wastewater, liberates labor, and does not require manual real-time monitoring and real-time control of the wastewater treatment process.

[0034] When the scraper 5 moves rightward along the wastewater surface, the scraper 5 pushes the floating foam on the liquid surface to move rightward, and the floating foam accumulates on the right side of the curved portion of the scraper 5. At this time, the straight plate portion of the scraper 5 is located below the wastewater surface, that is, the straight plate portion of the scraper 5 is located below the floating foam, so that the floating foam can be intercepted by the straight plate portion of the scraper 5 to prevent the floating foam from being pushed and then diving into the depth of the wastewater again, so as to ensure the efficiency of the floating foam suction. When in use, the scraper 5 with a hook-shaped cross-section can also intercept the floating foam by its straight plate portion to prevent the floating foam from diving into the depth of the wastewater again, so as to ensure the efficiency of the floating foam suction.

[0035] When the scraper 5 pushes the silt to move to the left, the scraper 5 will also push the wastewater to move to the left, causing the wastewater to flush out part of the silt gathered on the left side of the curved portion of the scraper 5, thereby reducing the silt scraping efficiency. Therefore, by providing an opening in the scraper 5 and providing a filter 207 at the opening, when the scraper 5 pushes the silt to move to the left, the wastewater flows through the opening of the scraper 5 corresponding to the filter 207, and the silt is intercepted by the filter 207, thereby avoiding the problem of reduced silt scraping efficiency due to the scraper 5 pushing the wastewater to move to the left.

[0036] Example 2

[0037] On the basis of Example 1, Figure 4-Figure 6 As shown, a shielding assembly is also included; the scraper 5 is connected to the shielding assembly; the shielding assembly includes a connecting block 208 and an arc plate 209; two connecting blocks 208 are welded on each scraper 5, and the connecting blocks 208 are set to an alloy material; an arc plate 209 is rotatably connected between each front and rear adjacent connecting blocks 208, and the arc plate 209 contacts the corresponding scraper 5, and the opening of the corresponding filter screen 207 on the scraper 5 is shielded by the arc plate 209.

[0038] When the scraper 5 moves to the right along the wastewater surface, there is an error in the height control of the wastewater surface. If the wastewater surface is immersed in the middle of the filter screen 207, the floating foam on the liquid surface is aligned with the filter screen 207, and the filter screen 207 cannot push the floating foam to move to the right, resulting in a decrease in the efficiency of removing the floating foam. Therefore, when the scraper 5 moves upward, the arc plate 209 rotates around the connecting block 208 toward the filter screen 207 under the action of gravity, so that the arc plate 209 fits the filter screen 207, and the corresponding filter screen 207 on the scraper 5 is moved upward. 07 is covered, and then the scraper 5 drives the parts thereon to move rightward, so that the scraper 5 and the curved plate 209 move rightward together to push the floating foam. When the scraper 5 moves downward, the curved plate 209 rotates back to its original position under the action of gravity. When in use, the opening of the scraper 5 corresponding to the filter screen 207 is covered by the curved plate 209, so that the scraper 5 and the curved plate 209 push the floating foam to move rightward together, avoiding the problem of reduced floating foam removal efficiency caused by the alignment of the floating foam on the wastewater liquid surface with the filter screen 207.

[0039] Example 3

[0040] On the basis of Example 2, Figure 5-Figure 7 As shown, the arc plate 209 is elastic.

[0041] Two grooves 93 are formed on the box body 1, and the grooves 93 match with the arc plate 209.

[0042] It also includes a counterweight bar 2010; each arc-shaped plate 209 is fixedly connected with a counterweight bar 2010, and the gravity of the counterweight bar 2010 is applied to the end of the arc-shaped plate 209.

[0043] It also includes a second filter screen 2011; each arc plate 209 has an opening, and a second filter screen 2011 is fixedly connected to the opening of each arc plate 209, and the sediment is intercepted by the second filter screen 2011.

[0044] The sprocket 205 and the chain 206 are both made of rust-proof materials to prevent corrosion.

[0045] When the scraper 5 moves the silt to the left, the arc plate 209 is subjected to the reaction force of the silt and the impact force of the water flow, so that the arc plate 209 is squeezed and deformed. When the scraper 5 moves to the top of the cavity 2 92, the motor 203 briefly stops driving the round rod 204 to rotate, so that the scraper 5 stops moving briefly. At this time, the scraper 5 stops moving the wastewater, that is, the arc plate 209 stops being subjected to the impact force of the water flow, so that the arc plate 209 rebounds, and the silt in the curved part of the scraper 5 moves to the left, and is moved into the cavity 2 92. When in use, the arc plate 209 used to move the floating foam can also be used to push the silt gathered in the curved part of the scraper 5 into the cavity 2 92, which greatly reduces the residual amount of silt in the curved part of the scraper 5, which is beneficial to improving the silt removal efficiency.

[0046] When the scraper 5 moves to above the cavity 2 92 , the front and rear ends of the scraper 5 are just aligned with the two grooves 93 , and the front and rear ends of the arc plate 209 stop contacting the box body 1 , and during the rebound of the arc plate 209 , the two ends of the arc plate 209 will not generate friction with the box body 1 , thereby avoiding slowing down the rebound speed of the arc plate 209 due to the existence of friction, and further avoiding reducing the effect of the arc plate 209 rebounding to push the sediment.

[0047] When the arc plate 209 is deformed by the reaction force of the sediment and the impact force of the water flow, the wastewater between the arc plate 209 and the scraper 5 can flow out from the opening of the arc plate 209 corresponding to the filter screen 2011, so that the scraper 5 can be fully squeezed and deformed to ensure the effect of rebounding and pushing the sediment.

[0048] When the arc plate 209 is rotated by gravity, the arc plate 209 will be affected by the resistance of wastewater and rotate slowly. If the scraper 5 switches from vertical upward movement to horizontal rightward movement, the arc plate 209 has not rotated back to its original position, and the arc plate 209 cannot cover the filter screen 207 in time, causing part of the foam to pass through the filter screen 207, thereby reducing the foam cleaning efficiency. The weight bar 2010 is used to increase the gravity on the end of the arc plate 209, thereby avoiding the problem of slow rotation of the arc plate 209 caused by the resistance of wastewater, thereby avoiding the problem of reduced foam cleaning efficiency caused by the slow rotation of the arc plate 209.

[0049] Although the present disclosure has been described with respect to only a limited number of embodiments, those skilled in the art having benefit of this disclosure will appreciate that various other embodiments can be devised without departing from the scope of the present invention.
