Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a silt removal device for water conservancy projects. Background Art

[0002] Water conservancy projects refer to various projects built to control, regulate and utilize natural surface water and groundwater in order to achieve the purpose of eliminating harm and promoting benefits. Water conservancy projects can be divided into flood control projects, embankments, reservoirs, flood storage and diversion areas, culverts, drainage projects, farmland water conservancy projects, irrigation projects, hydropower projects, shipping, and urban water supply and drainage projects according to their service objects. During the construction of water conservancy projects, there will be a lot of silt. The components of silt mainly include sediment, biological residues, organic matter, etc. Among them, finer particles have a larger specific surface area and a higher water content, which greatly affects the construction of water conservancy projects.

[0003] After searching, the authorized publication number is CN218322910U, which is a "hydraulic engineering silt removal device", which includes a shell and an extraction pump. A cover plate is arranged on the upper side of the shell, a fixed plate is fixedly connected to one side of the shell, and the extraction pump is fixedly connected to the upper side of the fixed plate. The two sides of the extraction pump are respectively fixedly connected with an extraction pipe and a discharge pipe, and the discharge pipe passes through the shell on the side away from the shell. A disassembly mechanism is arranged inside the shell, which improves the problem that after the first filter plate and the second filter plate are used for a long time, there will still be some silt and impurities in the gap between the first filter plate and the second filter plate, which may cause the filter plate to be blocked. Because the filter plate is not convenient to replace, the efficiency of the filter plate in filtering river water will decrease over time. The setting of the disassembly mechanism in the device enables the first filter screen to be replaced smoothly and conveniently after being used for a long time, and at the same time, it is also convenient enough to install the new first filter screen when it needs to be installed.

[0004] The above scheme squeezes the collected sludge downward by squeezing out water, separates the sludge and water, and then the sludge remains on the filter for recycling. However, during use, due to the high water content of the sludge, the water content of the sludge cannot be effectively reduced too much by squeezing, and during the squeezing process, the sludge adheres to the squeezing equipment and is difficult to clean, affecting the subsequent dredging use.

An outer ring 13 is fixedly connected to the side of the cross plate 11 close to the lifting pipe 9, and the lifting pipe 9 passes through and is fixedly connected to the outer ring 13. A connecting plate 14 is fixedly connected to the side of the cross plate 11 away from the outer ring 13, and the connecting plate 14 is fixedly connected to the tank cover 7.

[0028] Embodiment 2

[0029] Reference Figure 1 and Figure 2 , further improvements are made on the basis of the first embodiment:

[0030] A Jiaolong screw 21 is rotatably connected to the inner groove of the lifting pipe 9. A motor is provided at the top of the lifting pipe 9, and the output end of the motor passes through the top of the lifting pipe 9 and is fixedly connected to the top of the Jiaolong screw 21. The Jiaolong screw 21 and the inner groove of the lifting pipe 9 are adapted to each other. The sludge is lifted upward by the Jiaolong screw 21. In the process, not only the sludge can be cleaned, but also the mud blocks contained in the sludge will be broken up by the Jiaolong screw 21, which is convenient for sludge collection. At the same time, when the sludge rises through the Jiaolong screw 21, most of the water in the sludge will be naturally separated due to gravity, thereby reducing the efficiency of subsequent sludge dewatering.

[0031] The top edge positions of the machine base 1 on both sides of the lifting frame 10 are fixedly connected with vertical plates 22, and the side walls of the vertical plates 22 relative to the cross plate 11 are provided with sliding grooves 23, the cross plate 11 is adapted to and slidably connected with the sliding grooves 23, and a sliding rod 24 is penetrated and slidably connected with the position of the cross plate 11 near the sliding grooves 23, and the sliding rod 24 is fixedly connected between the upper and lower inner grooves of the sliding grooves 23. When the threaded rod 12 drives the cross plate 11 to move up and down, the two ends of the cross plate 11 slide in the sliding grooves 23 and are limited by the sliding rods 24, so that the up and down movement process of the cross plate 11 can be stable and safe.

[0032] The working principle of the utility model is as follows: when in use, the equipment moves to the dredging position through the machine base 1, and then the lifting pipe 9 is inserted into the silt at the dredging position, and then the motor is started to drive the dragon screw 21 to rotate. At this time, the dragon screw 21 lifts the silt from the bottom of the lifting pipe 9 to the top, and at the same time, the dragon screw 21 further breaks the silt to prevent mud blockage, and then the silt is sucked through the suction pipe 8 to be transported to the filter tank 5 in the separation tank 2, and at the same time, the motor inside the bottom column 3 is started to drive the chassis 4 and the upper filter tank 5 to rotate, and the high-speed rotating filter tank 5 produces a centrifugal effect. At this time, the silt is filtered and separated through the water filter membrane 15 in the filter port 6, so that the solid part of the silt remains in the filter tank 5, and the water passes through the water filter membrane 15. After entering the separation tank 2, it can be discharged from the outlet pipe of the separation tank 2 to complete the mud and water separation of the sludge. When the filter tank 5 is full or the sludge is cleaned, the motor above the lifting frame 10 is started, and the motor drives the threaded rod 12 to rotate. The threaded rod 12 rotates and drives the cross plate 11 to rise on the inside of the lifting frame 10. Then the cross plate 11 can lift the lifting pipe 9 and the tank cover 7 through the outer ring 13 and the connecting plate 14. Lifting the lifting pipe 9 can make the machine base 1 move normally. The tank cover 7 is lifted and opened, and the filter tank 5 can be taken out of the separation tank 2. When disassembling, the electromagnetic block 20 is powered off. At this time, the filter tank 5 is lifted upward. During the process, the positioning block 17 slides in the positioning groove 19, and the filter tank 5 can be disassembled, otherwise the installation can be completed.

Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
