[0002] Water supply pipelines are an essential piece of equipment in engineering water supply and drainage processes. As a channel for transporting water and impurities, the clogging performance of pipelines directly affects the progress and quality of the entire water supply and drainage operation. Therefore, a filtration device is needed to reduce the chance of pipeline blockage.

[0003] Currently, most existing engineering drainage filtration devices use single-layer filter plates for filtration. Due to the varying sizes of impurities, single-layer filtration is ineffective and cannot effectively prevent impurities from being blocked. Furthermore, the lack of cleaning devices leads to blockages caused by impurities, affecting drainage filtration. Utility Model Content

[0004] The purpose of this invention is to solve the problems of poor single-layer filtration effect and lack of cleaning device leading to impurity blockage and affecting drainage filtration, and to propose an engineering drainage filtration device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An engineering drainage filtration device includes a mounting box, an inlet pipe inserted into one end of the mounting box, filter screens snapped between the inner walls of multiple sides of the mounting box, a sliding groove on one side of the mounting box, a sliding rod slidably connected in the sliding groove, a first brush fixedly connected to one side of the sliding rod, the first brush brushing on the filter screen, guide plates fixedly connected to the inner walls of both sides of the mounting box, a screening cylinder fixedly inserted between the two ends of the mounting box, the bottom end of the guide plate fixedly connected to the top of the screening cylinder, multiple drainage holes on the circumference of the screening cylinder, a rotating disk rotatably connected to one end of the screening cylinder, a spiral auger fixedly connected to one side of the rotating disk, the spiral auger located inside the screening cylinder, an installation rod fixedly connected to one side of the rotating disk, a second brush fixedly connected to one side of the installation rod, the second brush brushing on the inner circumference of the screening cylinder, a sealing cap threaded onto one end of the screening cylinder, a collection trough snapped into the bottom of the mounting box, and a drain pipe inserted into one end of the collection trough.

[0007] Furthermore, the top of the mounting box is connected to a cover plate via hinges.

[0008] Furthermore, a guide plate with a C-shaped structure is fixedly connected to the outer wall of the other end of the mounting box.

[0009] Furthermore, baffles are slidably inserted between the inner walls on both sides of the guide plate.

[0010] Furthermore, a motor is fixedly connected to one side of the outer wall of the mounting box, and the output end of the motor is fixedly connected to the rotating disk.

[0011] Furthermore, a handle is fixedly connected to one side of the outer wall of the sealing cover, and an anti-slip sleeve is fitted onto the outer wall of the handle.

[0012] Furthermore, the bottom outer wall of the mounting box is fixedly connected with multiple support feet.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The water flow is initially filtered through a filter screen, and then filtered again using a screening cylinder, thereby fully filtering out impurities in the water flow and improving the filtration effect.

[0015] 2. By pulling the sliding rod, the first brush moves on the filter screen to clean the impurities on the filter screen. Then, driven by the motor, the second brush rotates, which moves on the inner circumference of the screening cylinder to clean the screening cylinder. At the same time, the rotating disc drives the spiral auger to rotate, thereby discharging the impurities from the screening cylinder for cleaning, thus preventing impurities from clogging the cleaning device.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-4 An engineering drainage filtration device includes a mounting box 1. One end of the mounting box 1 is connected to an inlet pipe 3. A filter screen plate 8 is snapped between the inner walls of the mounting box 1 on multiple sides. The filter screen plate 8 is used to perform preliminary filtration of the water flow. A guide plate 4 is welded to the outer wall of the other end of the mounting box 1. The guide plate 4 has a C-shaped structure. Baffles 19 are slidably inserted between the inner walls on both sides of the guide plate 4 to prevent water from flowing out of the mounting box 1. A sliding groove 5 is provided on one side of the mounting box 1. A sliding rod 6 is slidably connected in the sliding groove 5. A first brush 7 is fixed to one side of the sliding rod 6 by bolts. The first brush 7 brushes on the filter screen plate 8. Pulling the sliding rod 6 drives the first brush 7 to move forward, so that the first brush 7 brushes on the filter screen plate 8, thereby cleaning the impurities on the filter screen plate 8 onto the guide plate 4, and then out of the guide plate 4 for further processing.

[0023] Both inner walls of the mounting box 1 are welded with guide plates 9. A screening cylinder 10 is fixedly inserted between the two ends of the mounting box 1 to further filter the water flow. The bottom end of the guide plate 9 is fixedly connected to the top of the screening cylinder 10. The circumference of the screening cylinder 10 is provided with multiple drainage holes 11. A rotating disk 13 is rotatably connected to one end of the screening cylinder 10. A spiral auger 14 is fixed to one side of the rotating disk 13 by bolts. The spiral auger 14 is located inside the screening cylinder 10. A motor 12 is fixed to one outer wall of the mounting box 1 by bolts. The output end of the motor 12 is fixedly connected to the rotating disk 13. The rotating disk 13 drives the spiral auger 14 to rotate, thereby discharging impurities from the screening cylinder 10 for cleaning. A mounting rod 15 is fixed to one side of the rotating disk 13 by bolts, and a second brush 16 is fixed to one side of the mounting rod 15 by bolts. The second brush 16 brushes on the inner circumference of the screening cylinder 10. Driven by the motor 12, the rotating disk 13 rotates, thereby driving the second brush 16 to rotate, which in turn causes the second brush 16 to brush on the inner circumference of the screening cylinder 10, thereby cleaning the screening cylinder 10. A sealing cap 20 is threaded onto one end of the screening cylinder 10.

[0024] The bottom of the mounting box 1 is fitted with a collection trough 17, and one end of the collection trough 17 is connected to a drain pipe 18. Water flows into the collection trough 17 and then flows out from the drain pipe 18. The top of the mounting box 1 is connected to a cover plate 2 by a hinge, which facilitates the replacement of the filter screen plate 8. A handle is fixed to one side of the outer wall of the sealing cover 20 by bolts. The outer wall of the handle is fitted with an anti-slip sleeve. Unscrewing the sealing cover 20 facilitates the cleaning of the screening cylinder 10. Multiple support feet are welded to the bottom outer wall of the mounting box 1.

[0025] The working principle of this embodiment is as follows: In use, firstly, water flows into the installation box 1 from the inlet pipe 3. Then, the water flows onto the filter screen plate 8 and is initially filtered by the filter screen plate 8. The filtered impurities are temporarily stored on the surface of the filter screen plate 8. Next, the water flows into the screening cylinder 10 along the guide plate 9 and is filtered again by the screening cylinder 10. The impurities are temporarily stored in the screening cylinder 10. The water flows into the collection tank 17 through the drain hole 11 and is finally discharged from the drain pipe 18.

[0026] When cleaning is required, firstly, pull up the baffle 19 to remove it. Then, pull the slide rod 6 to move the first brush 7 forward, so that the first brush 7 brushes on the filter screen 8, thereby cleaning the impurities on the filter screen 8 onto the guide plate 4, and then out through the guide plate 4 for further processing. Next, unscrew the sealing cover 20 and start the motor 12. Driven by the motor 12, the rotating disk 13 rotates, thereby driving the second brush 16 to rotate, thereby causing the second brush 16 to brush on the inner circumference of the screening cylinder 10, thereby cleaning the screening cylinder 10. At the same time, the rotating disk 13 drives the spiral auger 14 to rotate, thereby discharging the impurities from the screening cylinder 10 for cleaning.
