Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of sewage treatment, and particularly relates to a trestle construction rainwater and sewage recovery treatment equipment. BACKGROUND

[0002] The trestle construction rainwater and sewage recovery treatment equipment is a device specially used in a trestle construction environment to collect, filter, distribute and recover rainwater and construction sewage, and realizes effective management and environmental protection discharge of water resources in a construction area through physical interception, distribution control and automatic operation.

[0003] After the sewage is recovered, physical filtration is needed to intercept and separate solid substances without chemical changes generated in the rainwater and sewage in the trestle construction, so as to realize a technical process of preliminary purification and system protection, and to provide basic conditions for subsequent treatment or reuse by removing solid impurities in the sewage through screening or interception.

[0004] When the existing equipment filters and treats impurities in the sewage, the separation of impurities in the sewage is mainly realized by relying on a filter plate. However, after the filter plate is used for a period of time, some irregularly shaped solid impurities are often stuck in the internal pores of the filter plate. In order to ensure the filtering effect, the filter plate needs to be disassembled and replaced with a new filter plate. However, during the operation process of disassembling and replacing the filter plate, the entire sewage treatment equipment must be in standby state, and the sewage cannot be treated during this period, thereby seriously reducing the treatment process of the sewage.

[0017] The beneficial effects of this invention are as follows: 1. The rainwater and sewage recycling and treatment equipment for trestle construction described in this invention uses a drive component.

The change in the tilt angle of the diversion plate directly affects the relative position of mesh one and mesh two with the cleaning component, realizing the switching of the filtration state of the two meshes.

Whether it is irregularly shaped solid impurities stuck in the second mesh during the filtration process, or impurities that clog the inner wall of the first mesh after it has played its filtration role for a period of time, they can all be removed by the cleaning component, ensuring the unobstructed flow of the mesh and maintaining a good filtration effect. With the close cooperation between the cleaning component and the drive component, sewage can flow continuously from the inlet pipe for treatment, avoiding the problem of the equipment needing to be idle due to the periodic cleaning and disassembly of the filter plate in existing equipment.

[0019] 3. In the rainwater and sewage recycling and treatment equipment for trestle construction described in this invention, during the period when the electromagnet and electromagnetic plate disconnect the magnetic force to collect metal impurities, the channel formed by the adsorption plate and the flipping plate loses its ability to screen impurities. If impurities filtered by the diversion plate fall into this channel at this time, they will mix into the subsequent materials to be treated, resulting in the impurities not being effectively screened out. The arc-shaped baffle can always intercept impurities at the bottom of the diversion plate, ensuring that impurities do not enter the magnetic separation component channel, thus maintaining the integrity and effectiveness of the overall impurity screening. By setting the insertion depth of the arc-shaped baffle to match the tilting and swinging amplitude of the lower half of the diversion plate, sewage can be continuously filtered on the surface of the diversion plate during the collection of metal impurities. At the same time, mesh one and mesh two can be switched to ensure that the metal impurity collection process does not interfere with the entire sewage filtration process. Attached Figure Description

[0023] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0024] like Figures 1 to 10As shown, the present invention provides a technical solution: a rainwater and sewage recycling and treatment device for trestle construction, including a treatment tank 1, a bearing seat 2 fixedly connected to the inner wall of the treatment tank 1, a diversion plate 3 fixedly connected to the outer wall of the shaft of the bearing seat 2, a mesh 4 uniformly opened on the upper half surface of the diversion plate 3, a mesh 5 uniformly opened on the lower half surface of the diversion plate 3, an inlet pipe 6 fixedly connected to the top of the treatment tank 1, a flow valve 7 provided on the outer wall of the inlet pipe 6, a water collection tank 22 fixedly connected to the bottom of the treatment tank 1, an outlet pipe 9 fixedly connected to one side of the water collection tank 22, a driving component provided at the bottom of the diversion plate 3, the driving component including a support wheel 11, the support wheel 11 can rotate and can increase the tilt angle of the diversion plate 3 when rotating, a cleaning component provided at the bottom of the diversion plate 3 that can alternately clean the mesh 4 and the mesh 5, and a magnetic separation component provided below the outlet end of the diversion plate 3, the magnetic separation component can screen and process impurities.

[0025] During operation: In the initial state, the support wheel 11 is attached to the bottom of the upper half of the diversion plate 3 to support it and keep the diversion plate 3 at a certain tilt angle; the sewage collected from the trestle construction site is discharged into the treatment tank 1 through the inlet pipe 6 and flows into the top of the upper surface of the diversion plate 3 from the outlet end of the inlet pipe 6; due to the tilt of the diversion plate 3, the sewage flows along the inclined surface of the diversion plate 3; at this time, the cleaning component blocks the first mesh 4, while the second mesh 5 is not blocked. The sewage is filtered when it flows through the second mesh 5 and flows out from the bottom of the diversion plate 3 through the inner wall of the second mesh 5. The impurities continue to flow along the surface of the diversion plate 3 until they flow out from the bottom of the diversion plate 3; however, during the filtration process on the inner wall of the second mesh 5, some irregularly shaped solid impurities will get stuck in the inner wall of the second mesh 5, gradually reducing its filtration effect; The drive assembly is activated periodically, causing the support wheel 11 to rotate and increase the tilt angle of the guide plate 3. At this time, the angle between the upper half of the guide plate 3 and the bearing seat 2 increases, and the inner wall of mesh 4 gradually detaches from the blockage of the cleaning component, beginning its filtering function. Meanwhile, the angle between the lower half of the guide plate 3 and the bearing seat 2 decreases, and the inner wall of mesh 5 is gradually blocked by the cleaning component. During this blocking process, impurities trapped in the inner wall of mesh 5 are pushed out by the cleaning component and flow out from the bottom outlet of the guide plate 3. After mesh 4 has performed its filtering function for a period of time, its inner wall will also be blocked by impurities. At this point, the support wheel 11 continues to rotate, and the guide plate 3 returns to its original tilt angle. During the process, mesh 4 is re-sealed, and the impurities stuck in its inner wall are pushed out by the cleaning component; meanwhile, mesh 5 is released from the sealed state and resumes its filtering function. In this way, mesh 4 and mesh 5 can alternately perform filtering functions with the cooperation of the drive component and the cleaning component, and can treat the impurities on their inner walls at each switch. In this way, sewage can flow in continuously from the inlet pipe 6 for treatment, avoiding the problem of the equipment needing to be on standby due to the periodic cleaning and disassembly of the filter plate in the existing equipment. The flow rate of wastewater is controlled by the flow valve 7, which creates a stable working environment for the drive and cleaning components, ensuring their normal operation. After the wastewater flows down through the inner wall of mesh 4 or mesh 5, it falls to the bottom of the collection tank 22. Since the bottom of the collection tank 22 is sloping, the wastewater can be concentrated at the outlet pipe 9 and can flow out of the entire equipment through the outlet pipe 9. After the impurities flow out through the bottom opening of the guide plate 3, they will enter the magnetic separation component. The magnetic separation component can screen and collect the metal solids and ordinary impurities in the impurities, making it convenient for people to recycle the metal substances in the waste. In the above embodiments, the drive component, through the rotation of the support wheel 11, can precisely control the tilt angle of the diversion plate 3. The change in the tilt angle of the diversion plate 3 directly affects the relative position of mesh 4 and mesh 5 with the cleaning component, realizing the switching of the two mesh filtration states. This alternating filtration method avoids the clogging problem caused by prolonged use of a single mesh, ensuring the continuity and stability of the filtration effect. Through the cleaning component, during the process of sealing and opening the mesh, the cleaning component can push out the impurities stuck in the inner wall of the mesh. Whether it is the irregularly shaped solid impurities stuck in mesh 5 during the filtration process, or the impurities that clog the inner wall of mesh 4 after a period of filtration, they can all be removed by the cleaning component, ensuring the unobstructed flow of the mesh and maintaining a good filtration effect. With the close cooperation between the cleaning component and the drive component, sewage can flow continuously from the inlet pipe 6 for treatment, avoiding the problem of the equipment needing to standby due to the periodic cleaning and disassembly of the filter plate in existing equipment.

[0026] like Figures 1 to 5 As shown, the drive assembly includes a motor 13, the output shaft of the motor 13 is fixedly connected to a rotating rod 10, the rotating rod 10 is rotatably connected to the inner wall of the processing box 1, and a support wheel 11 is fixedly connected to the outer wall of the rotating rod 10. Each outer wall of the support wheel 11 is fixedly connected to an extrusion outer ring 12.

[0027] During operation: In the initial state, mesh 4 is clogged by the cleaning component, and mesh 5 performs the filtering function. When the tilt angle of the diversion plate 3 is increased, the starting motor 13 drives the rotating rod 10 to rotate. The rotating rod 10 drives the support wheel 11 to rotate half a turn. The support wheel 11 will drive the extrusion outer ring 12 to gradually rotate to the bottom of the diversion plate 3. When the extrusion outer ring 12 rotates half a turn, its outer wall gradually contacts the bottom of the upper half of the diversion plate 3 and applies pressure. After rotating half a turn, the extrusion outer ring 12 adheres to the bottom of the upper half of the diversion plate 3, causing the overall tilt angle of the diversion plate 3 to increase. At this time, the diversion plate 3 maintains the tilt angle, mesh 4 performs the filtering function, while mesh 5 is clogged by the cleaning component. During the clogging process, the impurities stuck on the inner wall of mesh 5 are pushed out by the cleaning component and flow out from the outlet end at the bottom of the diversion plate 3.

[0028] like Figures 3 to 5 As shown, an arc-shaped slider 18 is symmetrically fixedly connected to the bottom of the lower half of the diversion plate 3, and an inner groove slide 17 is symmetrically fixedly connected to the side of the bearing seat 2. The arc-shaped slider 18 is slidably connected to the inner wall of the inner groove slide 17, and a torsion spring 19 is fixedly connected between one side of the arc-shaped slider 18 and the inner wall of the inner groove slide 17.

[0029] During operation: When the outer ring 12 rotates half a turn, the tilt angle of the guide plate 3 increases. At this time, the arc-shaped slider 18 connected to the lower half of the guide plate 3 slides along the inner wall of the inner groove slide 17 and squeezes the inner groove slide 17, completing the function switch between mesh 1 4 and mesh 2 5. Subsequently, after mesh 1 4 has been used for a period of time, the motor 13 continues to drive the outer ring 12 to rotate half a turn. At this time, the outer wall of the rotating rod 10 is in contact with the bottom of the upper half of the guide plate 3. Under the action of the torsion spring 19, the guide plate 3 returns to its original tilt angle, thus performing the second function switch between mesh 1 4 and mesh 2 5. This process is repeated to achieve the continuous alternating filtering effect of mesh 1 4 and mesh 2 5.

[0030] like Figures 3 to 4 As shown, the cleaning assembly includes multiple sets of arc-shaped cleaning rods 15. One end of each arc-shaped cleaning rod 15 is fixedly connected to one side of the bearing seat 2. The position and number of the arc-shaped cleaning rods 15 correspond to the position and number of the mesh holes 4. The inner wall of the mesh holes 4 is adapted to the shape of the arc-shaped cleaning rods 15. Multiple sets of arc-shaped cleaning rods 26 are fixedly connected to the other side of the bearing seat 2. The position and number of the arc-shaped cleaning rods 26 correspond to the position and number of the mesh holes 25. The inner wall of the mesh holes 25 is adapted to the shape of the arc-shaped cleaning rods 26.

[0031] During operation: In the initial state, one end of the arc-shaped cleaning rod 15 is inserted into the inner wall of mesh 4, sealing mesh 4; the arc-shaped cleaning rod 16 does not contact the inner wall of mesh 5, allowing sewage to flow through mesh 5 and out; when the diversion plate 3 increases its tilt angle under the action of the drive assembly, the angle between its upper half and the bearing seat 2 increases, and the arc-shaped cleaning rod 15 gradually detaches from mesh 4, releasing the seal and starting filtration; simultaneously, the angle between the lower half of the diversion plate 3 and the bearing seat 2 decreases, and the arc-shaped cleaning rod 16 gradually inserts into mesh 5, pushing out impurities and sealing mesh 5; when the diversion plate 3 returns to its original tilt state, the arc-shaped cleaning rod 15 re-inserts into mesh 4, pushing out impurities and sealing, and mesh 5 releases the seal and begins filtration, thus achieving automatic switching of filter meshes, continuous sewage treatment, timely cleaning of impurities, and avoiding downtime for maintenance.

[0032] like Figures 6 to 8 As shown, the inner wall of the treatment box 1 is fixedly connected with baffle 1 20 and baffle 21 respectively. Baffle 1 20 is located in the upper half of the diversion plate 3, and baffle 21 is located in the lower half of the diversion plate 3. Protective plates 14 are symmetrically fixedly connected to the upper surface of the diversion plate 3.

[0033] During operation: In the initial state, mesh 25 functions as a filter. At this time, one end of baffle 21 is attached to the upper surface of the lower half of the guide plate 3. When sewage and impurities flow to this point, baffle 21 intercepts the impurities on one side, allowing all sewage to pass through mesh 25 for filtration. When the tilt angle of the guide plate 3 increases under the action of the drive component, its upper surface is attached to one end of baffle 1 20, and baffle 21 is no longer attached to the upper surface of the guide plate 3. The impurities intercepted by baffle 21 in the previous round of filtration will slide down the surface of the guide plate 3 to the designated area at the bottom of the treatment tank 1 due to the loss of obstruction and the influence of gravity. At the same time, the upper half of the guide plate 3 is blocked by baffle 1 20, preventing sewage from flowing down directly and guiding the sewage to mesh 1 4, which is currently in the filtration state, to ensure that the sewage filtration work continues stably. When the guide plate 3 returns to its original tilt angle, baffle 1 20 is no longer attached to the upper half of the guide plate 3, and baffle 21 is reattached to the lower half of the guide plate 3. It should be noted that the movement frequency of the drive components needs to be properly controlled to avoid excessive accumulation of impurities intercepted on one side of baffle 21 and baffle 10.

[0034] like Figures 6 to 8 As shown, the magnetic separation component includes an electromagnet 24, which is located at the bottom of the diversion plate 3. An isolation plate 25 is fixedly connected to the bottom of the electromagnet 24. The bottom of the isolation plate 25 is fixedly connected to the bottom surface of the water collection tank 22. An electromagnet 24 is fixedly installed on one side of the adsorption plate 23. An opening slot 29 is provided on the side wall of the processing box 1. A flip plate 26 is provided on the inner wall of the opening slot 29. Electromagnetic plates 27 are symmetrically arranged inside the flip plate 26. The bottom of the water collection tank 22 is fixedly connected to the discharge tank 31. A collection box 32 is provided below the discharge tank 31.

[0035] During operation: After impurities fall from the bottom of the diversion plate 3, they will fall through the channel formed between the adsorption plate 23 and the flip plate 26. Ordinary solid impurities will fall directly through the channel and fall into the collection box 32 through the discharge bin 31 for collection. When impurities fall from the bottom of the diversion plate 3, the electromagnet 24 and the flip plate 26 are both in the open state, which can adsorb the metal solids on the sides of the electromagnet 24 and the two electromagnet plates 27. The isolation plate 25 is set to isolate the sewage collection area and the impurity collection area inside the water collection bin 22.

[0036] like Figures 6 to 8 As shown, a drive shaft 28 is rotatably connected to the inner wall of the treatment tank 1. The outer wall of the drive shaft 28 is fixedly connected to the inner wall at the center of the flip plate 26. A base platform 30 is fixedly connected to the bottom of the water collection tank 22. A collection box 1 32 is located above the base platform 30. A collection box 2 33 is provided on the top of the base platform 30. The collection box 2 33 is located on one side of the flip plate 26. An interception component for intercepting impurities is provided above the diversion plate 3.

[0037] During operation: As sewage continues to flow in, the metal impurities adsorbed on the sides of the adsorption plate 23 and the electromagnetic plate 27 quickly reach saturation. At this time, the drive shaft 28 is activated, causing the flip plate 26 and the electromagnetic plate 27 to flip. The flip plate 26 first rotates 90 degrees to be perpendicular to its original state, with one end just touching the bottom of the adsorption plate 23. Then, the magnetic force of the electromagnet 24 and the electromagnetic plate 27 is turned off, and the metal impurities adsorbed on the sides of the adsorption plate 23 fall onto the surface of the flip plate 26 and are collected with the original impurities. Next, the flip plate 26 continues to rotate 90 degrees. During this process, its surface gradually forms an inclined surface, and the angle of inclination becomes larger and larger. At this time, because the electromagnetic plate 27 disconnects the magnetic attraction and the opening slot 29 opens, the metal impurities on the surface can fall into the collection box 33 along the inclined surface. Finally, the flip plate 26 completes a 180-degree flip to return to its original state, and the electromagnet 24 and the electromagnetic plate 27 are restarted to continue working. As impurities filtered by the diversion plate 3 are continuously generated, during the process of collecting metal impurities by flipping the plate 26, the electromagnet 24 and the electromagnetic plate 27 are disconnected. At this time, the channel formed by the adsorption plate 23 and the flipping plate 26 cannot screen the impurities. Therefore, during the rotation of the flipping plate 26, the interception component will be triggered to temporarily intercept the bottom of the diversion plate 3 to prevent the filtered impurities from falling into the channel formed by the adsorption plate 23 and the flipping plate 26.

[0038] like Figure 2 , Figure 9 and Figure 10 As shown, the interception component includes an arc-shaped partition 34, with fixed rods 35 fixedly connected to both sides of the arc-shaped partition 34. A slider 36 is fixedly connected to the outer wall of the fixed rod 35. An insertion slot 44 is provided on the bottom inner wall of the diversion plate 3. The arc-shaped partition 34 and the insertion slot 44 correspond to and fit each other. A sliding groove 37 is symmetrically provided on the side wall of the processing box 1. The slider 36 is slidably connected to the sliding groove 37. A gear assembly is provided on the outside of the processing box 1. The gear assembly can drive the slider 36 to slide along the inner wall of the sliding groove 37.

[0039] During operation: When the drive shaft 28 starts, it causes the flip plate 26 to flip and collect metal impurities. Its rotation will trigger the gear assembly, which will drive the slider 36 to slide along the inner wall of the groove 37. When the slider 36 slides, it drives the arc-shaped partition 34 to insert into the insertion slot 44 through the fixed rod 35. The insertion depth of the arc-shaped partition 34 can adapt to the tilting and swinging amplitude of the lower half of the diversion plate 3, ensuring that when the tilt of the diversion plate 3 changes, the arc-shaped partition 34 always plays the role of intercepting impurities at the bottom of the diversion plate 3, preventing them from entering the magnetic separation component. During the period when the electromagnet 24 and the electromagnetic plate 27 disconnect the magnetic force to collect metal impurities, the channel formed by the adsorption plate 23 and the flipping plate 26 loses its ability to screen impurities. If impurities filtered by the diversion plate 3 fall into this channel at this time, they will mix into the subsequent materials to be treated, causing the impurities to be unable to be effectively screened out. The arc-shaped baffle 34 can always intercept impurities at the bottom of the diversion plate 3, ensuring that impurities do not enter the magnetic separation component channel, thus maintaining the integrity and effectiveness of the overall impurity screening. By setting the insertion depth of the arc-shaped baffle 34 to match the tilting and swinging amplitude of the lower half of the diversion plate 3, the sewage can be continuously filtered on the surface of the diversion plate 3 during the collection of metal impurities. At the same time, mesh 1 4 and mesh 2 5 can be switched to ensure that the metal impurity collection process does not interfere with the entire sewage filtration process.

[0040] like Figures 9 to 10 As shown, the outer wall of the processing box 1 is symmetrically rotatably connected with a rotating shaft 39, and the outer wall of the rotating shaft 39 is fixedly connected with a connecting rod 38. One end of the connecting rod 38 is fixedly connected to the outer wall of the fixed rod 35.

[0041] During operation: When the drive shaft 28 drives the tilting plate 26 to rotate 90 degrees, at the beginning of the rotation, the gear assembly drives the rotating shaft 39 to rotate. The rotating shaft 39 drives the slider 36 to slide along the inner wall of the slide groove 37 through the connecting rod 38, allowing the arc-shaped baffle 34 to intercept all impurities that continue to be filtered. When the drive shaft 28 drives the tilting plate 26 to rotate 90 degrees, as the rotation process is nearing its end and the tilting plate 26 is about to complete its tilting, the gear assembly drives the rotating shaft 39 to rotate in the opposite direction. The slider 36 slides in the opposite direction along the inner wall of the slide groove 37, stopping the interception of impurities. The impurities can continue to fall into the channel for magnetic separation.

[0042] like Figures 9 to 10 As shown, connecting brackets 43 are symmetrically fixedly connected to both ends of the drive shaft 28. One end of each connecting bracket 43 is fixedly connected to a rack plate 41, and the other end of each connecting bracket 43 is fixedly connected to a rack plate 42. Gears 40 are fixedly connected to the outer wall of the rotating shaft 39. The teeth of the two sets of rack plates 41 and rack plate 42 can mesh with the teeth of the gears 40.

[0043] During operation: Rack plate 1 41 and rack plate 2 42 are fixed in two groups on the outer wall of the same connecting frame 43 and are 180 degrees symmetrical to each other. When the drive shaft 28 drives the flip plate 26 to rotate 90 degrees, at the beginning of the rotation, the connecting frame 43 drives one group of rack plates 1 41 to rotate around the drive shaft 28, so that the teeth of rack plate 1 41 mesh with the teeth of gear 40, driving the rotating shaft 39 to rotate, and then the slider 36 slides along the inner wall of the slide groove 37, and the arc-shaped partition 34 begins to intercept; when the drive shaft 28 continues to drive the flip plate 26 to rotate another 90 degrees, when the rotation is about to end, it drives the other group of rack plates 2 42 to mesh with the teeth of gear 40, and this time the rotation direction is opposite to the first time, so that the rotating shaft 39 rotates in the opposite direction, and the slider 36 slides back to the original state along the inner wall of the slide groove 37, and the arc-shaped partition 34 no longer intercepts the bottom of the diverting plate 3.
