Description
Technical Field
[0001] This application relates to the technical field of wastewater treatment, and in particular to a construction site wastewater recycling treatment device. Background Technology
[0002] Modern engineering projects are developing towards large-scale, large-scale, and modern directions. The number of projects in major cities is increasing exponentially. During the construction process, a large amount of construction wastewater and solid waste will be generated. Construction wastewater mainly comes from the wastewater discharged by construction workers in their daily lives on the construction site, such as wastewater discharged from kitchens, toilets, and shower rooms, as well as wastewater discharged from various production and processing processes on the construction site.
[0003] For wastewater discharged during various production and processing processes at construction sites, the existing collection method usually involves diverting it through drainage ditches. However, during the diversion process, a large amount of construction solid residue is mixed in with the wastewater and enters the wastewater treatment device at the same time, which can cause blockage or even damage to the wastewater treatment device. Therefore, it is necessary to separate the wastewater from the construction solid residue mixed in with it.
[0004] In existing technologies, such as Chinese patent CN205307891U, a construction site wastewater treatment device is disclosed, which effectively solves the problems of incomplete removal of silt and waste of water resources. The technical solution involves a sedimentation tank with a sedimentation chamber containing a sedimentation device. The sedimentation device has an inlet extending outwards from the tank. A drive device is located at the top of the sedimentation device, and a rotating shaft is located inside. Multiple impellers are arranged around the circumference of the shaft. A sand-washing pipe is fixedly connected to the shaft and located below the impellers. An outlet pipe is connected to the top of the sedimentation device, which in turn connects to a mud-water separator. The mud-water separator has an outlet connected to a water purification tank. The structure is reasonable and standardized. Through sedimentation and silt removal of construction site wastewater, the treated water is virtually free of solid particles, allowing for water reuse without clogging pipes and conserving water resources, thus providing significant environmental benefits.
[0005] In the aforementioned prior art, sedimentation tanks are used to treat silt, and they are all laid flat on the ground, which takes up a large area. In addition, sedimentation tanks use automatic sedimentation to separate sewage and solid silt, which takes a long time to settle, resulting in poor cleaning efficiency.
[0006] Secondly, in existing technologies, sedimentation tanks are ineffective at filtering construction site wastewater, and some fine sand and gravel cannot be effectively filtered. Summary of the Invention

[0044] The following is in conjunction with the appendix Figure 1-12 This application will be described in further detail.
[0045] This application discloses a construction wastewater recycling and treatment device. This application can filter construction wastewater through a spiral-shaped construction wastewater treatment tank 2. The construction wastewater treatment tank 2 is placed vertically, which not only reduces the footprint of the device and allows the construction wastewater recycling and treatment device to be set up in a limited space, but also allows the wastewater to flow from top to bottom along the construction wastewater treatment tank 2 through the spiral structure. During the flow, the wastewater is filtered in multiple stages, which improves the efficiency of wastewater treatment.
[0046] See Figure 1As shown, a construction wastewater recycling treatment device includes a support column 1 and a construction wastewater treatment tank 2 fixedly connected to the outer wall of the support column 1; the support column 1 is fixed on the ground, and the construction wastewater treatment tank 2, which is spiral-shaped, is fixedly installed on the outer wall of the support column 1.
[0047] An inclined storage groove 44 is provided at the upper end of the support column 1. The purpose of the water storage groove is to allow the wastewater in the water storage groove to enter the inlet of the construction wastewater treatment tank 2, so as to prevent the wastewater from accumulating in the water storage groove.
[0048] The storage groove 44 is connected to the construction wastewater treatment tank 2. The upper end of the construction wastewater treatment tank 2 is the inlet, and the outlet is directly below the inlet. In this invention, the construction wastewater first enters the storage groove 44 at the upper end of the support column 1. Then, the wastewater enters the construction wastewater treatment tank 2 through the inlet and undergoes multi-layer filtration to filter the construction solid residue in the wastewater. The wastewater is then filtered to achieve the recycling of construction wastewater.
[0049] The construction wastewater treatment tank 2 has a spiral structure, and the inner side of the construction wastewater treatment tank 2 is provided with several separators 3 at equal intervals for separating construction wastewater from construction solid residue; the function of the separators 3 is to separate the wastewater from the solid residue in the wastewater.
[0050] The lower side wall of the construction wastewater treatment tank 2 is equipped with collectors 4 for collecting construction solid residues, corresponding to the position of the separator 3; the function of the collectors 4 is to collect the solid residues blocked by the separation plate 31.
[0051] See Figure 2 and Figure 3 As shown, the separator 3 includes several sets of separation components 30 arranged at equal intervals from top to bottom along the inner wall of the construction wastewater treatment tank 2 to separate construction solid residues. The function of the separation components 30 is to facilitate the separation of construction wastewater and construction solid residues.
[0052] The separator 30 includes two symmetrical separator plates 31 that are tilted toward the inside of the construction wastewater treatment tank 2. Each separator plate 31 has a movable plate 32 hinged to one side of its opposite side. The separator plates 31 are equipped with a cleaning component 33. The cleaning component 33 is used to clean the construction solid residue blocked by the separator plates 31, so as to prevent the construction solid residue from accumulating over a long period of time and causing the filter holes 34 on the separator plates 31 to become blocked.
[0053] The movable plate 32 is located between two separation plates 31. The separation plates 31 are inclined, so the movable plate 32 and the two separation plates 31 form an isosceles trapezoidal structure. The two separation plates 31 block the solid residue in the construction wastewater. The blocked solid residue gradually accumulates in front of the movable plate 32 through the isosceles trapezoidal structure formed by the separation plates 31 and the movable plate 32. After a certain volume of solid residue has accumulated in front of the movable plate 32, the movable plate 32 rotates around the hinge point, so that the solid residue accumulated at its front end is collected uniformly.
[0054] See Figure 3 and Figure 4 As shown, two symmetrical separation plates 31 have equally spaced filter holes 34 of the same diameter. Multiple sets of separation components 30 are set inside the construction wastewater treatment tank 2. The diameter of the filter holes 34 gradually decreases from top to bottom along the inner wall of the construction wastewater treatment tank 2, forming a multi-stage filtration, thereby achieving different filtration effects on the construction wastewater. The multiple sets of separation components 30 inside the construction wastewater treatment tank 2 can perform multi-stage filtration on the construction wastewater, ensuring that solid residues of different volumes in the construction wastewater can be cleaned, thereby greatly improving its cleaning efficiency.
[0055] The movable plate 32 has an L-shaped structure. The horizontal part of the movable plate 32 abuts against the construction wastewater treatment tank 2. The construction wastewater treatment tank 2 has a disposal trough 35 for unloading construction solid residue directly below the movable plate 32. The movable plate 32 is equipped with an opening and closing mechanism 36. Two separation plates 31 block the solid residue in the construction wastewater. The blocked solid residue gradually accumulates in front of the movable plate 32 through the isosceles trapezoidal structure formed by the separation plates 31 and the movable plate 32. When a certain volume of solid residue accumulates in front of the movable plate 32, the movable plate 32 can no longer support the weight of the solid residue. At this time, the movable plate 32 begins to rotate around the hinge point, and the disposal trough 35 hidden at the lower end of the movable plate 32 opens until all the solid residue accumulated in front of the movable plate 32 enters the disposal trough 35.
[0056] When the active tank is opened, some solid residues do not enter the disposal tank 35. At this time, the missed solid residues are filtered through multiple stages by separation plates 31 with different sizes of filter holes 34 until all solid residues in the construction wastewater of the entire construction site are cleaned up.
[0057] See Figure 4 and Figure 5As shown, the opening and closing mechanism 36 includes a first plate 361 fixed inside the construction wastewater treatment tank 2 and directly behind the movable plate 32. Two first telescopic columns 362 are hinged to the side of the first plate 361 closest to the movable plate 32. A cross-shaped limiting groove is opened at the end of the first telescopic column 362 away from the movable plate 32. A second telescopic column 363 is slidably installed in the cross-shaped limiting groove. The second telescopic column 363 has a cross-shaped structure. The second telescopic column 363 is slidably set on the first telescopic column 362, and the second telescopic column 363 is limited by the cross-shaped structure to prevent the second telescopic column 363 from rotating during sliding. A compression spring 366 is sleeved between the second telescopic column 363 and the first telescopic column 362. The elastic force of the compression spring 366 supports the first telescopic column 362 and the second telescopic column 363.
[0058] The end of the second telescopic column 363 away from the first telescopic column 362 is hinged to the rear side of the movable plate 32, and the first telescopic column 362 and the second telescopic column 363 are set at an angle, with the position of the first telescopic column 362 being higher than that of the second telescopic column 363.
[0059] In the specific implementation process, the rear side of the movable plate 32 is supported by the inclined telescopic column 362 and the telescopic column 363, so that the movable plate 32 always rests between the two separation plates 31, preventing the disposal groove 35 at the lower end of the movable plate 32 from opening. In addition, compression springs 366 are sleeved on the telescopic column 362 and the telescopic column 363. By controlling the elasticity of the compression springs 366, the weight of the solid residue that the front end of the movable plate 32 can support is controlled, thereby realizing the automatic opening and closing of the movable plate 32.
[0060] When the weight of the solid residue on the front side of the movable plate 32 is greater than the supporting force of the compression spring 366 that abuts the rear side of the movable plate 32 on the movable plate 32, the movable plate 32 rotates around the hinge point, the disposal groove 35 at the lower end of the movable plate 32 opens, and the solid residue accumulated on the front side of the movable plate 32 is collected into the disposal groove 35.
[0061] See Figure 5 As shown, an annular I-shaped block 364 is slidably fitted onto the first telescopic column 362. A sliding sleeve 365 is fixedly connected to the side of the annular I-shaped block 364 away from the first plate 361. An annular groove is formed at the end of the sliding sleeve 365 away from the annular I-shaped block 364, and a compression spring 366 abuts inside the annular groove. The compression spring 366 is fitted onto the first telescopic column 362 and the second telescopic column 363. An adjusting component 37 for adjusting the elasticity of the compression spring 366 is provided on the annular I-shaped block 364. The sliding sleeve 365 is slidable and abuts against the compression spring 366. The distance between the sliding sleeve 365 and the second telescopic column 363 is the compression stroke of the compression spring 366.
[0062] The position of the sliding sleeve 365 is changed so that it moves towards the direction of the second telescopic column 363. At this time, the distance between the second telescopic column 363 and the sliding sleeve 365 is shortened, so the length of the compression spring 366 decreases and the elastic force of the compression spring 366 increases. This ensures that the supporting force of the compression spring 366 on the movable plate 32 also increases synchronously. Therefore, the volume of solid residue that can be stored and accumulated on the front side of the movable plate 32 is larger, and vice versa.
[0063] See Figure 6 and Figure 7 As shown, the adjustment assembly 37 includes a vertical plate 370 fixed to the upper end of the construction wastewater treatment tank 2. A rotating shaft 371 is rotatably installed on the inner side of the vertical plate 370. Two winding rollers 372 are fixedly installed on the rotating shaft 371. A twisted rope 373 is fixedly connected to each of the two winding rollers 372. The ends of the two twisted ropes 373 away from the winding rollers 372 are fixed to the two side walls inside the construction wastewater treatment tank 2 by a telescopic tension spring 379. The function of the tension spring 379 is to ensure that the twisted ropes 373 can move within a certain range.
[0064] A twisted rope 373 is fixedly connected to the winding roller 372. Therefore, rotating the winding roller 372 can drive the twisted rope 373 to wind around the winding roller 372, thereby driving the twisted rope 373 to move.
[0065] See Figure 8 As shown, the left side of the rotating shaft 371 rotates through the vertical plate 370 and connects to the rocker wheel 375. The rocker wheel 375 has a serrated groove on its outer side, and a limiting claw 378 abuts against the serrated groove. The limiting claw 378 is set on the outer wall of the construction wastewater treatment tank 2 through a limiting spring 376. The function of the limiting claw 378 is to fix the position of the rocker wheel 375. After the operator drives the winch 373 to the designated position through the rocker wheel 375, the rocker wheel 375 needs to be fixed. At this time, the limiting claw 378 engages with the serrated groove on the outer wall of the rocker wheel 375, thereby fixing the rocker wheel 375.
[0066] Inside the construction wastewater treatment tank 2, directly below the two winding rollers 372, there are two reversing wheels 374 that rotate. The rope 373 is wound on the reversing wheels 374. Limiting plates 377 are fixed at equal intervals on the two side walls inside the construction wastewater treatment tank 2. Limiting holes are opened on the limiting plates 377. The rope 373 is slidably set in the limiting holes. A quick clamping module 38 is provided on the rope 373.
[0067] In the specific implementation process, when it is necessary to change the supporting force of the compression spring 366, the operator presses the limiting claw 378 that is locked on the rocker wheel 375 as needed to separate the limiting claw 378 from the rocker wheel 375.
[0068] Next, the operator turns the rocker wheel 375. When the rocker wheel 375 rotates, it drives the rotating shaft 371 and the winding roller 372 to rotate. When the winding roller 372 rotates, it pulls the twisted rope 373 to move in the direction of the winding roller 372. When the twisted rope 373 moves, it drives the sliding sleeve 365 to move in the direction of the first telescopic column 362 through the fixed column 380. At this time, the distance between the sliding sleeve 365 on the first telescopic column 362 and the second telescopic column 363 gradually decreases, and the compression spring 366 on the first telescopic column 362 and the sliding sleeve 365 is gradually compressed.
[0069] After the compression spring 366 is compressed, the elastic force of the compression spring 366 increases. Therefore, the supporting force of the compression spring 366 on the movable plate 32 increases. The maximum volume of solid residue that the movable plate 32 can support can be changed by adjusting the position of the sliding sleeve 365.
[0070] See Figure 9 As shown, the quick clamping module 38 includes fixed posts 380 fixed at equal intervals on the twisted rope 373, and clamping grooves for clamping are formed at equal intervals on the fixed posts 380; the fixed posts 380 are provided with clamping grooves that connect with the annular I-shaped block 364, and the annular I-shaped block 364 and the twisted rope 373 are connected by the quick clamping module 38.
[0071] A clamping plate 381 is fixed on the annular I-shaped block 364. Two vertically symmetrical clamping rods 382 are fixed on both the left and right sides of the clamping plate 381. The opposite sides of the two vertically adjacent clamping rods 382 are fixedly connected to a fixing rod 384 that meshes with the clamping groove on the fixing post 380 through a clamping spring rod 383.
[0072] Both fixing rods 384 have a pressing rod 385 hinged to their side ends, and the two pressing rods 385 are arranged in a cross manner at the side ends of the clamping plate 381.
[0073] In the specific implementation process, the operator first holds the two symmetrical pressing rods 385 and applies a certain pressure, so that the two pressing rods 385 on the side closer to the operator are relatively close, while the side of the two pressing rods 385 away from the operator drives the fixing rod 384 to move towards the clamping groove on the fixing post 380, until the fixing rod 384 on the two clamping plates 381 clamps and engages with the fixing post 380, ensuring that the annular I-shaped block 364 and the twisted rope 373 are fixedly connected.
[0074] See Figure 10 , Figure 11and Figure 12 As shown, the cleaning assembly 33 includes a cleaning rod 330 that slides up and down on the front side of two separating plates 31, and a scraping rod 386 that slides up and down on the front side of a movable plate 32. A return spring 390 is connected to the upper end of the scraping rod 386 and the movable plate 32. In the initial state, the scraping rod 386 is located at the uppermost end of the front side of the movable plate 32, and the return spring 390 is in an inelastic state without being subjected to external force.
[0075] A scraping spring 387 is fixed on the vertical linkage rod 331 located near the movable plate 32. The end of the scraping spring 387 away from the scraping rod 386 is connected to an abutment rod 389. When the movable plate 32 rotates around the hinge point, the scraping spring 387 fixed on the vertical linkage rod 331 located near the movable plate 32 uses its own elasticity to keep the abutment rod 389 against the surface of the movable plate 32, but it does not put pressure on the movable plate 32. When the vertical linkage rod 331 moves downward, the abutment rod 389 can always drive the scraping rod 386 to move from top to bottom on the surface of the movable plate 32, scraping away the solid residue adsorbed on the front side of the movable plate 32.
[0076] Vertical linkage rods 331 are fixedly connected to the upper end of the scraping rod 386 and the upper ends of the two sweeping rods 330. A horizontal rod 332 is installed on the upper end of the three vertical linkage rods 331. A vertical rod 333 is fixedly connected to the side end of the horizontal rod 332 and slidably installed on the side wall of the construction wastewater treatment tank 2. The sweeping rods 330 on the separation plate 31 are controlled to move up and down by the vertical linkage rods 331. When the operator pulls the horizontal rod 332, the horizontal rod 332 drives the sweeping rods 330 to move upward through the vertical linkage rods 331. When the operator presses the horizontal rod 332, the operator drives the sweeping rods 330 to move downward through the vertical linkage rods 331.
[0077] The upper ends of several horizontal bars 332 are connected together by triangular bars 334; the function of triangular bars 334 is to ensure that multiple sets of horizontal bars 332 inside the construction wastewater treatment tank 2 can move synchronously.
[0078] Let's look again. Figure 11 The diagram shows the structure of collector 4, which includes a collection box 40 disposed directly below the disposal trough 35. The collection box 40 is used to collect solid residues that fall from the disposal trough 35 for unified processing.
[0079] The collection box 40 has a collection port on its side, and a controllable sealing door 45 is hinged to the collection port. When solid residue enters the collection box 40, the operator can collect the solid residue inside the collection box 40 by controlling the opening and closing of the sealing door 45.
[0080] An inclined collection net 41 is fixedly connected inside the collection box 40. The function of the collection net 41 is to separate the construction wastewater mixed in with the collected solid residue and put the collected construction wastewater back into the construction wastewater treatment tank 2 for filtration. Therefore, the construction wastewater can be filtered to the bottom of the collection box 40 through the collection net 41. A collection pipe 42 is fixed to the bottom of the collection box 40. The end of the collection pipe 42 away from the collection box 40 extends to the top of the support column 1. A water pump 43 is installed on the collection pipe 42. After the construction wastewater is filtered to the bottom of the collection box 40, the construction wastewater is pumped into the storage groove 44 at the top of the support column 1 through the collection box 40 and the water pump 43 for recycling treatment.
[0081] The implementation principle of this embodiment is as follows:
[0082] (1): The operator first diverts the construction wastewater to the storage groove 44 at the top of the support column 1. Then the construction wastewater carries the solid residue mixed in it along the construction wastewater treatment tank 2 for multi-stage filtration treatment.
[0083] (2): Construction wastewater first comes into contact with the separation plate 31 and movable plate 32 inside the construction wastewater treatment tank 2. The separation plate 31 blocks and filters the solid residue in the construction wastewater. When a certain amount of solid residue accumulates on the front side of the movable plate 32, the elastic force of the compression spring 366 that abuts the rear side of the movable plate 32 is less than the solid residue accumulated on the front side of the movable plate 32. At this time, the movable plate 32 rotates around the hinge point. Then, the solid residue accumulated on the front side of the movable plate 32 enters the collection tank 40 through the discard trough 35 on the lower side of the movable plate 32 for collection. When the movable plate 32 rotates, some solid residue enters the front side of the subsequent separation plate 31 and movable plate 32 along the construction wastewater treatment tank for filtration. Then, the above operation is repeated until the solid residue in the entire construction wastewater is filtered.
[0084] (3): In order to increase the amount of solid residue collected on the front side of the movable plate 32, the filtration efficiency of the movable plate 32 and the separation plate 31 is adjusted in turn. First, the operator rotates the winding roller 372 to drive the rope 373 to move. When the rope 373 moves, it drives the sliding sleeve 365 to move towards the first telescopic column 362, thereby changing the distance between the two ends of the compression spring 366. By changing the distance between the two ends of the compression spring 366, the elasticity of the compression spring 366 is increased, thereby ensuring that the movable plate 32 can support a larger volume of solid residue, thereby achieving rapid filtration of construction wastewater at the construction site.
[0085] (4): After the solid residue in the construction wastewater is collected into the collection box 40, the solid residue contains some construction wastewater. After filtration, it is transported back to the construction wastewater treatment box 2 for recycling until all the construction wastewater is filtered.
[0086] The embodiments described herein are preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
