On the one hand, it cannot be used reasonably to achieve the purpose of water conservation. On the other hand, the water accumulation easily causes the construction site to be dirty, thus failing to ensure the cleanliness of the construction site. In this way, it is necessary to precipitate and filter the rainfall water before draining it to avoid the pollution of the construction site by rainfall water accumulation. In addition, the water that is easy to discharge can be effectively recycled to reduce the construction cost. However, in the current drainage device for building construction, since the rainfall water contains sediments such as silt, concrete residues, etc., it is easy to cause blockage inside the device, and it is inconvenient for construction workers to clean the sediments, thus affecting the use efficiency of the device.

[0021] At the same time, the present invention also discloses a method for using a drainage device for building construction, which has simple steps, reasonable design and is convenient for use. The method is characterized in that the method comprises the following steps:

[0022] Step 1: Movement of drainage device for building construction:

[0023] Use the universal wheel to move the drainage device for house construction to the required construction position, connect the water to be discharged to the pumping pipe, turn on the pump, and the pump will pump the discharged water into the sedimentation tank through the delivery pipe;

[0024] Step 2: Sedimentation treatment of the discharged water to obtain precipitated water:

[0025] Step 201, the discharged water flows to the surface of the horizontal filter plate after being precipitated in the three sedimentation chambers, and is filtered through the horizontal filter plate to obtain precipitated water and sediment;

[0026] Step 202: During the filtering process of the horizontal filter plate, when it is necessary to scrape off the sediment on the surface of the horizontal filter plate, the lifting and rotating mechanism is operated to drive the scraper to descend to the surface of the horizontal filter plate and rotate to scrape off the sediment on the surface of the horizontal filter plate, so that the sediment on the surface of the horizontal filter plate falls to the bottom of the sedimentation box;

[0027] Step 3: Filtration and discharge of water after sedimentation:

[0028] After sedimentation, the water flows into the filter box through the partition, and flows to the drain pipe after being filtered by multiple vertical filters. Open the drain valve to discharge the water.

[0029] The above method of use is characterized in that: in step 3, when the vertical filter needs to be cleaned or replaced:

[0030] First, turn the bolt to remove it from the upper limit block and the lower threaded hole, move the U-shaped block to squeeze the spring to move the U-shaped block away from the vertical filter screen, and when the lower limit block of the U-shaped block moves out of the hole in the circumferential frame of the vertical filter screen;

[0031] Secondly, pull the handle, and the handle takes the vertical filter out of the filter box, and takes out the vertical filter, so as to facilitate cleaning the surface of the vertical filter or replacing the vertical filter;

[0032] Then, insert the cleaned or replaced vertical filter into the filter box, loosen the U-shaped block, and the spring extends to push the U-shaped block to move closer to the vertical filter until the lower limit block of the U-shaped block is inserted into the card hole, and bolts are inserted into the upper limit block and the lower threaded hole to fix it;

[0033] When slag discharge is required, the sewage discharge valve is opened and the turntable is rotated. The turntable drives the screw to rotate, and the fixed block connected with the screw thread moves. The fixed block drives the scraper to move. During the movement of the scraper, the pressure exerted on the inner spring gradually decreases. Under the action of the elastic force, the inner spring drives the scraper to move downward, and the sediment on the inclined plate in the sedimentation box is scraped to the sewage discharge pipe outlet. The screw conveyor is operated to rotate synchronously, so that the sediment at the sewage discharge pipe outlet is discharged through the screw conveyor.

[0034] In step 202, the lifting and rotating mechanism is operated to drive the scraper to descend to the surface of the horizontal filter plate and rotate to scrape off the sediment on the surface of the horizontal filter plate. The specific process is as follows:

[0035] The telescopic end of the operating cylinder extends, and the extension of the telescopic end of the cylinder pushes the mounting seat, the motor and the rotating shaft to move downward, and the downward movement of the rotating shaft drives the scraper to descend to the surface of the horizontal filter plate; wherein, during the downward movement of the motor, the guide rod slides along the sliding groove;

[0036] Then operate the motor to rotate, and the motor rotation drives the scraper to rotate through the rotating shaft, thereby scraping off the sediment on the surface of the horizontal filter plate.

[0037] Compared with the prior art, the present invention has the following advantages:

[0038] 1. Simple structure, reasonable design, compact overall, easy to move and operate, and can be reused.

[0039] 2. The sedimentation mechanism adopted includes a baffle assembly and a filter assembly. The filter assembly includes a lifting and rotating mechanism, a scraper and a horizontal filter plate. Three sedimentation chambers are formed by the baffle assembly to realize three-level sedimentation of the slag water. On the one hand, the heights of the three sedimentation chambers increase successively, which slows down the flow rate of the slag water, so that the slag water can be automatically precipitated and separated for a longer time; on the other hand, the lifting and rotating mechanism drives the scraper to scrape off the sediment on the horizontal filter plate, reducing internal blockage of the device and effectively adapting to the large water volume operation requirements of building construction.

[0040] 3. The horizontal filter plate is used to perform preliminary filtration on the water after three sedimentations, so that the water after three sedimentations can be filtered by its own weight, and the sediment on the horizontal filter plate can be scraped off into the sedimentation chamber for discharge.

[0041] 4. The vertical filter is used to filter the water again after sedimentation, and the residue on the vertical filter can fall to the bottom of the vertical filter by its own weight, which reduces the clogging time of the vertical filter and increases the service life.

[0042] 5. The vertical filter screen used is detachable and can be vertically inserted in the filter cavity, so that the vertical filter screen can be easily cleaned or replaced.

[0043] 6. The drainage device used in building construction has simple steps, is easy to implement and easy to operate, ensuring the separation of sediment and water.

[0044] 7. The method of using the drainage device for building construction is easy to operate and has good effect. First, the drainage device for building construction is moved, and then the discharged water is precipitated to obtain precipitated water, and then the precipitated water is filtered and discharged, which improves the separation effect and effectively adapts to the operation requirements of high water volume.

[0045] In summary, the present invention is reasonably designed, and the sedimentation chamber and the filter chamber are arranged to realize the sedimentation and filtration separation of the slag water, reduce the internal blockage of the device, and effectively adapt to the large water volume operation requirements of building construction; and it is easy to move and operate and can be reused.

[0094] like Figure 7 A method for using a drainage device for building construction is shown, comprising the following steps:

[0095] Step 1: Movement of drainage device for building construction:

[0096] Use the universal wheel 20 to move the drainage device for building construction to the required construction position, connect the water to be discharged to the pumping pipe 12, start the pumping pump 13, and the pumping pump 13 pumps the discharged water into the sedimentation tank 3 through the delivery pipe 14;

[0097] Step 2: Sedimentation treatment of the discharged water to obtain precipitated water:

[0098] Step 201, the discharged water flows to the surface of the horizontal filter plate 8 after being precipitated in the three sedimentation chambers, and is filtered by the horizontal filter plate 8 to obtain precipitated water and sediment;

[0099] Step 202: During the filtering process of the horizontal filter plate 8, when it is necessary to scrape off the sediment on the surface of the horizontal filter plate 8, the lifting and rotating mechanism is operated to drive the scraper 9 to descend to the surface of the horizontal filter plate 8 and rotate to scrape off the sediment on the surface of the horizontal filter plate 8, so that the sediment on the surface of the horizontal filter plate 8 falls to the bottom of the sedimentation box 3;

[0100] Step 3: Filtration and discharge of water after sedimentation:

[0101] After sedimentation, the water flows into the filter box 4 through the partition 2-1, and flows to the drain pipe 17 after being filtered by multiple vertical filter screens 15. The drain valve 18 is opened to discharge the water.

[0102] In this embodiment, when the vertical filter screen 15 needs to be cleaned or replaced in step 3:

[0103] First, turn the bolt 2605 to remove it from the upper limit block 2607 and the lower threaded hole 2604, and move the U-shaped block to squeeze the spring 2603 to move the U-shaped block away from the vertical filter 15. When the lower limit block 2601 of the U-shaped block moves out of the hole 27 in the circumferential frame 15-1 of the vertical filter 15;

[0104] Secondly, pull the handle 16, the handle 16 takes the vertical filter 15 out of the filter box 4, and takes out the vertical filter 15, so as to facilitate cleaning the surface of the vertical filter 15 or replacing the vertical filter 15;

[0105] Then, the cleaned or replaced vertical filter screen 15 is inserted into the filter box 4, the U-shaped block is loosened, and the spring 2603 is extended to push the U-shaped block to move in the direction close to the vertical filter screen 15, until the lower limit block 2601 of the U-shaped block is inserted into the card hole 27, and the bolt 2605 is inserted into the upper limit block 2607 and the lower threaded hole 2604 to fix it;

[0106] When slag discharge is required, the sewage valve 21-1 is opened and the rotary disk 23 is rotated. The rotary disk 23 rotates with the screw rod 22, and the fixed block 2501 threadedly connected with the screw rod 22 moves. The fixed block 2501 moves with the scraper 2503. During the movement of the scraper 2503, the pressure exerted on the inner spring 2502 gradually decreases. Under the action of the elastic force, the inner spring 2502 moves with the scraper 2503 downward to scrape the sediment on the inclined plate 24 in the sedimentation box 3 to the sewage pipe 21.

[0107] The screw conveyor is operated synchronously to rotate, so that the sediment at the outlet of the sewage pipe 21 is discharged through the screw conveyor;

[0108] In step 202, the lifting and rotating mechanism is operated to drive the scraper 9 to descend to the surface of the horizontal filter plate 8 and rotate to scrape off the sediment on the surface of the horizontal filter plate 8. The specific process is as follows:

[0109] The telescopic end of the operating cylinder 11-3 extends, and the extension of the telescopic end of the cylinder 11-3 pushes the mounting seat 11-4, the motor 11 and the rotating shaft 10 to move downward, and the rotating shaft 10 moves downward to drive the scraper 9 to descend to the surface of the horizontal filter plate 8; wherein, during the downward movement of the motor 11, the guide rod 11-5 slides along the sliding groove 11-1-1;

[0110] Then, the motor 11 is operated to rotate, and the rotation of the motor 11 drives the scraper 9 to rotate through the rotating shaft 10, so as to scrape off the sediment on the surface of the horizontal filter plate 8.

[0111] In this embodiment, a scraper 9 is provided to rotate and scrape the surface of the horizontal filter plate 8 to prevent the filter holes of the horizontal filter plate 8 from being blocked by sediment during the water filtering process.

[0112] In summary, the present invention is reasonably designed, and the sedimentation chamber and the filter chamber are arranged to realize the sedimentation and filtration separation of the slag water, reduce the internal blockage of the device, and effectively adapt to the large water volume operation requirements of building construction; and it is easy to move and operate and can be reused.
