Technical Field

[0001] This utility model relates to the technical field of sand and gravel plant initial rainwater collection and sedimentation filtration reuse tank. Background Technology

[0002] During the production process at sand and gravel plants, a large amount of sand and gravel particles, dust, and small amounts of oil and other pollutants remain on the ground. In the early stages of rainfall, rainwater carries these pollutants, forming runoff with high turbidity and high suspended solids. If discharged directly, this will not only waste water resources but also pollute the surrounding water environment.

[0003] Currently, sand and gravel plants on the market collect wastewater mixed with sand and gravel through filtration ponds during the rainy season, which can save water resources and also carry out sand recovery, allowing the collected sand and gravel to be reused.

[0004] However, in the initial rainwater collection and sedimentation filtration and reuse ponds of such sand and gravel plants, the cleaning of sediment is mostly done manually, and there is a lack of subsequent sand and gravel processing procedures, resulting in poor efficiency in sediment collection and reuse. Utility Model Content

[0005] The purpose of this invention is to provide an initial rainwater collection and sedimentation filtration reuse tank for sand and gravel plants, in order to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an initial rainwater collection and sedimentation filtration reuse tank for sand and gravel plants, including a treatment tank. A platform is fixedly installed at the front end of the treatment tank. A sedimentation tank is located inside the treatment tank and at the rear end of the platform. An overflow platform is fixedly connected inside the treatment tank and at the rear end of the sedimentation tank. A filtration tank is located inside the treatment tank and at the rear end of the overflow platform. A clear water storage tank is located inside the treatment tank and at the rear end of the filtration tank. A platform is fixedly installed on the side of the treatment tank. The system includes a reuse tank. A fixed frame is fixedly connected to the top of the treatment tank, which is located above the sedimentation tank. A sand pusher plate is slidably connected inside the fixed frame. A sand discharge trough is opened at the rear end of the sedimentation tank. A movable baffle is slidably connected inside the sand discharge trough. A screw feeder is fixedly connected to the bottom end of the sand discharge trough. A sand discharge pipe is fixedly connected to the lower end of the screw feeder on the side away from the sand discharge trough. A movable plate is slidably connected to the surface of the reuse tank. A sand inlet trough is opened on the surface of the movable plate. A drying fan is installed on the side end of the reuse tank.

[0007] According to the above technical solution, the fixed frame is internally rotatably connected to a lead screw, the surface of the lead screw is threadedly connected to a connecting rod, and the lower end of the connecting rod is fixedly connected to a pusher plate.

[0008] According to the above technical solution, a hydraulic rod is fixedly installed on the outer end of the treatment pool, and a movable baffle is fixedly connected to the top end of the hydraulic rod.

[0009] According to the above technical solution, a second motor is installed at the top of the screw feeder, and a first motor is installed at the top of the fixed frame.

[0010] According to the above technical solution, an air outlet groove is provided on the rear surface of the movable plate, and an installation groove is provided inside the reuse pool, with the movable plate slidably connected inside the installation groove.

[0011] According to the above technical solution, a water inlet pipe is fixedly connected to the front end of the platform, a water inlet hole is opened at the rear end of the platform, and a grating plate is installed at the front end of the water inlet pipe.

[0012] According to the above technical solution, a primary filter screen is installed at the upper part of the filter pool, a fine filter screen is installed inside the filter pool and below the primary filter screen, an adsorption layer is installed inside the filter pool and below the fine filter screen, and a water outlet is fixedly connected to the bottom side of the filter pool.

[0013] According to the above technical solution, a water pump is installed inside the clear water storage tank.

[0014] Compared with existing technologies, the beneficial effects achieved by this utility model are as follows: the grating plate can intercept larger floating objects in rainwater, such as leaves and plastic waste, preventing them from entering the subsequent treatment structure and affecting the treatment effect. The lower end of the platform is used to connect the inlet pipe, sending the sewage to the inside of the sedimentation tank. Inside the sedimentation tank, sand and gravel are settled and overflow water is separated. When the water exceeds the height of the overflow platform, it can flow into the inside of the filter tank, where it is filtered by three filtration devices. The filtered water can be discharged into the clear water storage tank through the outlet at the lower end of the filter tank. When the settled sand and gravel reach a certain height, the sand discharge trough can be opened by moving the movable baffle inside the sand discharge trough, discharging the sand and gravel in the sedimentation tank into the inside of the screw feeder. At the same time, the sand pusher plate in the fixed frame moves left and right, using the sand pusher plate to push the sand and gravel from the left end of the sedimentation tank to the right end of the sand discharge trough. After sand and gravel fall into the screw feeder, they are transported to the discharge pipe by the screw and spiral blades at the rear end of the feeder. Finally, the sand and gravel pass through the discharge pipe, enter the sand trough, and fall into the recycling tank for recovery. The recovered sand and gravel contain some water and can be dried by a drying fan. When sunlight is strong, a sliding plate can be opened to utilize sunlight for drying. When rainwater overflows and enters the filter tank, it undergoes multi-layer filtration and adsorption treatment through a primary filter, a fine filter, and an adsorption layer. The clean water collected in the clear water storage tank can be pumped out for use. This device automatically separates the collected sand and gravel from the rainwater. An automatic pushing structure is incorporated during sand and gravel collection to improve discharge efficiency. The collected sand and gravel can then be dried. Attached Figure Description

[0022] Please see Figure 1-4The initial rainwater collection and sedimentation filtration reuse pond in the sand and gravel plant area includes a treatment pond 1. A platform 2 is fixedly installed at the front end of the treatment pond 1. A sedimentation pond 6 is located inside the treatment pond 1 and at the rear end of the platform 2. An overflow platform 10 is fixedly connected inside the treatment pond 1 and at the rear end of the sedimentation pond 6. A filtration pond 11 is located inside the treatment pond 1 and at the rear end of the overflow platform 10. A clear water storage pond 12 is located inside the treatment pond 1 and at the rear end of the filtration pond 11. A reuse pond 15 is fixedly installed at the side end of the treatment pond 1. The top of the treatment pond 1... A fixed frame 8 is fixedly connected above the sedimentation tank 6. A sand pusher 21 is slidably connected inside the fixed frame 8. A sand discharge trough 7 is opened at the rear end of the sedimentation tank 6. A movable baffle 18 is slidably connected inside the sand discharge trough 7. A screw feeder 16 is fixedly connected to the bottom end of the sand discharge trough 7. A sand discharge pipe 17 is fixedly connected to the lower end of the screw feeder 16 on the other side away from the sand discharge trough 7. A movable plate 27 is slidably connected to the surface of the reuse tank 15. A sand inlet trough 28 is opened on the surface of the movable plate 27. A drying fan 29 is installed on the side end of the reuse tank 15. The lower end of the platform 2 is used to connect the water inlet pipe to send sewage into the sedimentation tank 6. The sedimentation tank 6 is used to settle sand and gravel and separate overflow water. When the water exceeds the height of the overflow platform 10, it can flow into the filter tank 11. It is filtered by three filtration devices in the filter tank 11. The filtered water can be discharged into the clear water storage tank 12 through the water outlet 14 at the lower end of the filter tank 11. Once the collected sand and gravel reach a certain height, the sand discharge trough 7 can be opened by moving the movable baffle 18 inside the trough, discharging the sand and gravel from the sedimentation tank 6 into the screw feeder 16. Simultaneously, the pusher plate 21 inside the fixed frame 8 moves left and right, pushing the sand and gravel from the left end of the sedimentation tank 6 to the right end of the sand discharge trough 7. After falling into the screw feeder 16, the sand and gravel are transported to the sand discharge pipe 17 by the screw and spiral blades at the rear end of the screw feeder 16. Finally, the sand and gravel pass through the sand discharge pipe 17, through the sand inlet trough 28, and fall into the recycling tank 15 for recovery. The recovered sand and gravel contains some water and can be dried by the drying fan 29. When the sunlight is strong, the movable plate 27 can be slid open to utilize sunlight for drying.

[0023] Please see Figure 1-2 The fixed frame 8 is internally connected to a lead screw 23, and the surface of the lead screw 23 is threaded to a connecting rod 22. The lower end of the connecting rod 22 is fixedly connected to a sand pusher plate 21. When the lead screw 23 is rotated, the connecting rod 22 inside the fixed frame 8 can be moved left and right, which in turn moves the sand pusher plate 21 left and right, making it easier to push the sand and gravel accumulated in the sedimentation tank 6 to the sand discharge trough 7. The interior of the sedimentation tank 6 is designed with a slope to facilitate the flow of water and the collection of slurry.

[0024] Please see Figure 1-2 A hydraulic rod 19 is fixedly installed on the outer end of the treatment tank 1, and a movable baffle 18 is fixedly connected to the top of the hydraulic rod 19.

[0026] Please see Figure 1-3 The rear surface of the movable plate 27 has an air outlet slot 30, and the interior of the reuse tank 15 has an installation slot 31, through which the movable plate 27 is slidably connected. When the drying fan 29 is started for drying, exhaust can be achieved using the air outlet slot 30. The installation slot 31 is located at the upper interior of the reuse tank 15, allowing for easy insertion and installation of the movable plate 27. When the reuse tank 15 needs to be opened, the movable plate 27 can be slid.

[0027] Please see Figure 1 A water inlet pipe 3 is fixedly connected to the front end of platform 2, and a water inlet hole 5 is opened at the rear end of platform 2. A grating plate 4 is installed at the front end of the water inlet pipe 3. The grating plate 4 can intercept larger floating objects in the rainwater, such as leaves and plastic waste, to prevent them from entering the subsequent treatment structure and affecting the treatment effect.

[0028] Please see Figure 1-4 A primary filter screen 24 is installed at the upper part of the filter tank 11. A secondary filter screen 25 is installed inside the filter tank 11 below the primary filter screen 24. An adsorption layer 26 is installed inside the filter tank 11 below the secondary filter screen 25. A water outlet 14 is fixedly connected to the bottom side of the filter tank 11. When rainwater overflows and enters the filter tank 11, it undergoes multi-layer filtration and adsorption treatment through the primary filter screen 24, secondary filter screen 25, and adsorption layer 26. The clean water after multi-layer filtration flows to the clean water storage tank 12 through the water outlet 14.

[0029] Please see Figure 1 A water pump 13 is installed inside the clean water storage tank 12. The clean water collected inside the clean water storage tank 12 can be pumped out and used by the water pump 13.
