Description

Technical Field

[0001] The utility model relates to the field of sludge removal, in particular to a device for removing sludge from a water conservancy river channel. Background Art

[0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. They are also called water projects. Water conservancy projects require the construction of different types of hydraulic structures such as dams, dikes, spillways, sluices, water inlets, channels, ferries, rafts, fishways, etc. to achieve their goals. Scours and siltation often occur in water conservancy rivers, which are prone to water disasters and hinder the development of water conservancy. In the process of water conservancy river regulation, a large amount of silt will be produced at the bottom. Current dredging devices mostly use pipes to directly extract the bottom silt.

[0003] Most existing sludge removal devices use filter screens to filter sludge and separate sludge from sewage. However, if there are small particles in the sewage, the filtering effect of the filter screen may be limited. These small particles may pass through the pores or mesh of the filter screen and cannot be completely filtered out, resulting in the filtrate still containing particles.

[0004] The prior art (publication number: CN218405615U) discloses a sludge removal device for water conservancy construction, which belongs to the technical field of sludge removal devices for water conservancy construction. The device specifically comprises a bottom plate, a shovel bucket, a sludge pump, a sludge box and a storage box. The shovel bucket is provided with a feed hopper, a first adjustment mechanism and a second adjustment mechanism are provided on the bottom plate, a first filter screen is provided in the sludge box, a water outlet pipe is provided below the first filter screen, a water seepage trough is provided on the storage box, and a stirring blade is provided in the storage box;

[0005] Although the above patent can separate water and mud in the sludge through the seepage trough, the first filter screen and the outlet pipe, it has the following disadvantages. When in use, the first filter screen can only filter the larger particles in the sludge, and the smaller particles may be discharged into the river, affecting the filtering effect. Further improvement is needed. For this reason, we propose a water conservancy river silt removal device. Utility Model Content

[0006] The main purpose of the utility model is to provide a water conservancy river channel silt removal device, which can effectively solve the problems in the background technology.

[0009] Preferably, the processing device includes an extrusion tank, which is arranged at the lower end of the discharge valve pipe, and electric cylinders are installed on the left and right ends of the extrusion tank. A screen is provided on the lower left portion of the outer cylindrical surface of the extrusion tank, and a groove is provided on the lower right portion of the outer cylindrical surface of the extrusion tank. The two conveying ends of the electric cylinders extend into the extrusion tank and are transmission-connected with a disc, a buffer pad is installed on the left end of the right disc, and the outer surface of the disc is movably connected to the inner wall surface of the extrusion tank.

[0010] Preferably, the output end of the motor extends into the processing tank and is connected to a first stirring blade and a second stirring blade, and the lower end of the second stirring blade is movably connected to the lower inner wall of the processing tank.

[0011] Preferably, a drain valve pipe is inserted and connected to the lower end of the processing tank, and a filter is arranged inside the drain valve pipe.

[0012] Preferably, the liquid suction end of the medicine pump extends into the medicine tank.

[0013] Preferably, the squeeze tank is mounted on the base plate via a support rod.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. By setting up a hollow ring, a one-way valve and a medicine pump, the medicine can be transported to the sludge. When in use, pour the flocculant medicine into the medicine tank, control the medicine pump to transport the medicine to the hollow ring, and then enter the discharge pipe from the one-way valve to combine with the sludge, promote the aggregation and precipitation of solid particles in the sludge, separate the water from the particles, and improve the filtering effect. At the same time, the medicine can be evenly combined with the sludge and enter the treatment tank at the same time as the sludge, reducing the subsequent stirring time and improving the work efficiency;

The electric cylinder on the left is controlled to drive the disc on the left to move to the right to squeeze the treated sludge so that the residual water in the sludge is completely separated. Then, the electric cylinder on the right is controlled to move to the right so that the sludge falls from the groove, reducing the weight of the sludge, facilitating subsequent transportation and processing, and reducing transportation costs.
