Description

Technical Field

[0001] This utility model relates to the field of water conservancy system technology, specifically to a water conservancy construction filtration device. Background Technology

[0002] The filtration system in water conservancy projects is a crucial link in filtering impurities and suspended matter from water. It ensures the basic quality of the water source and guarantees the normal operation of the water conservancy project. The filtration system can effectively reduce suspended solids and impurities in the water, intercept silt flowing in from external water bodies, and prevent it from affecting subsequent water conservancy system components.

[0003] Currently, the filtration systems in water conservancy construction projects are basically responsible for intercepting silt and impurities. In general maintenance work, staff need to use a variety of equipment to enter the drained pool to clean the silt. Since the system pool usually has a certain depth and the amount of silt usually accumulates in large quantities at the bottom of the pool, the dredging work is difficult and labor-intensive.

[0004] To address the aforementioned issues, we have made improvements and proposed a filtration device for hydraulic construction. Utility Model Content

[0018] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0019] Example: Figures 1-3 As shown, a water conservancy construction filtration device includes a water accumulation buffer tank 1. A filter tank 2 is fixedly installed inside the water accumulation buffer tank 1. A sedimentation tank 5 is movably installed at the bottom inside the filter tank 2. Filter media frames 6 are installed on the top surfaces of both the left and right ends of the sedimentation tank 5. Filter screens 7 are fixedly installed inside the filter media frames 6. Lifting lugs 8 are fixedly welded to the front and rear ends of both the left and right ends of the top surface of the sedimentation tank 5. Lifting equipment groups 9 are fixedly installed on the ground surface on both the left and right sides outside the water accumulation buffer tank 1. The lifting equipment groups 9 are connected to the lifting lugs 8 by chains.

[0020] An inlet pipe is fixedly installed on the top left side of the water-accumulating buffer tank 1. The inner edge of the top surface of the filter tank 2 is rounded. An overflow drain pipe 3 is fixedly embedded on the top right side of the filter tank 2. The height of the overflow drain pipe 3 is the same as the height of the filter media frame 6. A spare drain outlet is opened in the center of the bottom surface of the filter tank 2. A spare drain pipe 4 is fixedly installed at the bottom of the spare drain outlet. A solenoid valve is fixedly installed at the top of the spare drain pipe 4.

[0021] The front and rear ends of the filter media frame 6 are fixedly welded to the front and rear ends of the top surface of the sedimentation tank 5, respectively. The left and right sides and the top of the filter screen 7 are fixedly connected to the filter media frame 6, and the bottom of the filter screen 7 is fixedly connected to the bottom surface inside the sedimentation tank 5.

[0022] The lifting equipment group 9 includes a DC motor 10. The bottom of the DC motor 10 is fixedly connected to the ground by bolts. Two winch rollers 11 are set behind the DC motor 10. The four winch rollers 11 are located on the external ground above the four corners of the water accumulation buffer pool 1. The two winch rollers 11 in a single lifting equipment group 9 are coaxially fixedly connected by a linkage shaft 12.

[0023] The shaft of the DC motor 10 is coaxially and fixedly connected to the first winch roller 11 at the rear. Auxiliary guide rollers 13 are installed on the outer ground edges above the four corners of the water buffer pool 1. The four auxiliary guide rollers 13 are aligned with the four winch rollers 11 respectively. The two lifting equipment groups 9 have the same structure.

[0024] The inside of the winch roller 11 is wound with chain ropes. The four chain ropes pass through four auxiliary guide rollers 13 respectively, and their bottom ends are fixedly connected to the four lifting lugs 8 of the siltation tank 5.

[0025] Working principle: In use, this type of hydraulic construction filtration device continuously inputs water into the water-accumulating buffer tank 1 through the inlet pipe, and the water accumulates in the filter tank 2. When the water level reaches the overflow drain pipe 3, it will flow out from the pipe. The overflow drain pipe 3 bends downward to form a height to control the overflow water level. Its other end can be connected to the subsequent hydraulic system as needed. The water flowing into the filter tank 2 is filtered by the filter screen 7 in the filter material frame 6, which intercepts different particulate impurities. The intercepted impurities and underwater mud from the external water area gradually accumulate in the siltation tank 5. After a period of time, the water input is stopped, and the DC motor 10 of the lifting equipment group 9 is started. Each winch roller 11 rotates synchronously, and the siltation tank 5 is raised to the top of the water-accumulating buffer tank 1 by winding the chain rope connected to the lifting lug 8. The staff can then start sludge removal and filter material maintenance. The water in the filter tank 2 is drained by opening the backup drain pipe 4. The small amount of silt after drainage can be cleaned by personnel entering and rinsing.
