If these sludge is not cleaned in time, it will reduce the storage capacity of water conservancy facilities, affect the functions of flood control, irrigation, navigation, etc. Traditional sludge cleaning methods are relatively extensive, often focusing only on digging out the sludge, while ignoring the separation and treatment of impurities in the sludge. The sludge without impurity separation is randomly piled up, not only occupying a large amount of land, but also possibly causing secondary pollution, such as heavy metals and organic matter in the sludge polluting the soil and groundwater.

[0027] Please refer to Figures 1-5 The utility model provides technical schemes:

[0029] The pretreatment mechanism 4 comprises a crushing and mixing integrated barrel 41, a heat preservation inner container 42, a crushing roller 43 and a multi-angle transmission assembly 44, the crushing and mixing integrated barrel 41 is arranged at the top of the separation outer box 1, the heat preservation inner container 42 is fixedly connected to the inner side of the crushing and mixing integrated barrel 41, the multi-angle transmission assembly 44 is movably connected to the inner side of the heat preservation inner container 42, and the crushing roller 43 is movably connected to the inner side of the multi-angle transmission assembly 44.

[0030] In the embodiment: the crushing and mixing integrated barrel 41 can be used for pretreatment of silt in different conditions, and can be used for mixing and crushing of silt with large viscosity or agglomerated silt, and can be used for more comprehensive and better pretreatment through the multi-angle transmission assembly 44, and can be used for further extrusion and crushing of agglomerated silt through the crushing roller 43, and the heat preservation inner container 42 can be used for avoiding the problem of poor pretreatment effect caused by large temperature difference.

[0031] Specifically, as Figure 1 , Figure 2 , Figure 5As shown, the vibrating screen mechanism 3 includes a screen barrel 31, a support ring 32, an extension strut 33, a compression spring 34, a screen plate 35, and an electric cam 36.

[0032] Specifically, as shown in Figure 1 , Figure 2 , Figure 5 As shown, the screen barrel 31 is movably connected to the bottom of the inside of the separation inner barrel 2, the support ring 32 is fixedly connected to the inside of the screen barrel 31, the extension strut 33 is fixedly connected to the bottom of the top support ring 32, the extension strut 33 is fixedly connected to the top of the bottom support ring 32, the screen plate 35 is fixedly connected to the bottom of the top extension strut 33, and the screen plate 35 is fixedly connected to the top of the bottom extension strut 33.

[0033] Specifically, as shown in Figure 1 , Figure 2 , Figure 5 As shown, the compression spring 34 is fixedly connected to the inside of the extension strut 33, and the electric cam 36 is movably connected to the inside of the screen barrel 31. The electric cam 36 is arranged at the bottom of the top screen plate 35 and at the top of the bottom screen plate 35.

[0034] In this embodiment: the sludge can fall into the screen barrel 31 by opening the electromagnetic induction valve 9 on the inside of the transition port 6, and at this time, the electric cam 36 is started. Because the lengths of the protrusions on the two sides of the electric cam 36 are different, the electric cam 36 will push the top and bottom screen plates 35 when rotating, and will squeeze the extension strut 33 and the inside compression spring 34 between the screen plate 35 and the support ring 32. The compression spring 34 continuously accumulates elastic potential energy and rebounds, driving the screen plate 35 to vibrate. In this process, in cooperation with the gravity generated by the falling sludge, the screen barrel 31 can perform irregular multi-stage screening on the sludge, thereby realizing impurity separation.

[0035] Specifically, as shown in Figure 1 , Figure 2 As shown, the multi-angle transmission assembly 44 includes a main shaft 44a, a linkage arm 44b, an electric rotating frame 44c, and a hydraulic rod 44d.

[0036] Specifically, as shown in Figure 5 , Figure 3 As shown, the main shaft 44a is movably connected to the inside of the heat preservation inner liner 42, the linkage arm 44b is rotatably connected to the outside of the main shaft 44a, the electric rotating frame 44c is movably connected to the outside of the linkage arm 44b, the crushing roller 43 is movably connected to the inside of the electric rotating frame 44c, the hydraulic rod 44d is rotatably connected to the outside of the linkage arm 44b, and the hydraulic rod 44d is rotatably connected to the outside of the main shaft 44a.

[0037] In the embodiment, the motor provided in the crushing and mixing integrated barrel 41 is started to drive the rotation of the shaft 44a, and then drive the rotation of the outer linkage arm 44b. The inner motor of the linkage arm 44b drives the rotation of the electric rotating frame 44c to realize mixing and stirring. At the same time, the hydraulic rod 44d pulls the linkage arm 44b to make the electric rotating frame 44c reciprocate up and down during rotation and shaft rotation, thereby strengthening the mixing effect, fully mixing the dispersing agent, water and viscous sludge, preventing the sludge from adhering to the screen plate 35 and the inner wall during separation, causing blockage. When the sludge is agglomerated, in addition to the above rotation and swing operation, the crushing roller 43 inside the electric rotating frame 44c is started to turn over and crush the agglomerated sludge, reduce its hardness and size, cooperate with water and dispersing agent to soften it, avoid damage to the screen plate 35 during separation, affect the separation effect.

[0038] Specifically, as shown in Figure 4 、 Figure 3 , the top of the crushing and mixing integrated barrel 41 is movably connected with the feeding port 5, and the bottom of the crushing and mixing integrated barrel 41 is movably connected with the transition port 6. The transition port 6 is fixedly connected to the top of the separation outer box 1. The bottom of the separation outer box 1 is movably connected with the sewage outlet 7. The outer side of the separation outer box 1 is fixedly connected with the supporting leg 8.

[0039] Specifically, as shown in Figure 4 Figure 1 Figure 2 Figure 5 , the inner side of the transition port 6 is movably connected with the electromagnetic induction valve 9.

[0040] In the embodiment, the feeding is carried out through the feeding port 5, the sealing and communication transfer are carried out through the transition port 6 and the electromagnetic induction valve 9 inside the transition port 6, the sludge is quickly discharged through the sewage outlet 7, and the supporting leg 8 can support the whole device.

[0041] Working principle: after the sludge is cleaned and collected and transported to the separation area, the collected sludge is poured into the heat preservation inner barrel 42 inside the crushing and mixing integrated barrel 41 through the inlet 5, water and dispersing agent are added, and different pretreatments are carried out according to the state of the sludge. When the sludge is in a viscous state, the crushing roller 43 inside the electric rotating frame 44c is not started, but only the motor provided in the crushing and mixing integrated barrel 41 is started to make the main shaft 44a rotate around the axis and drive the connecting arm 44b outside the main shaft 44a to rotate, the motor inside the connecting arm 44b drives the electric rotating frame 44c to rotate, so that the mixing and stirring effect of the electric rotating frame 44c rotating around the axis is achieved, and the whole electric rotating frame 44c can be reciprocatingly swung up and down during rotation and rotation around the axis by pulling the connecting arm 44b through the hydraulic rod 44d, so that the mixing and stirring effect is further enhanced, the dispersing agent and water can be fully mixed with the viscous sludge, and the adhesion of the screen plate 35 and the inner wall during separation is avoided. When the sludge is in a lump state, the effect of rotation around the axis and self-rotation and swinging is repeated, and the crushing roller 43 inside the electric rotating frame 44c is started to stir and crush the sludge inside, so that the hardness and size of the sludge are reduced, and the hardness of the sludge is reduced to soften it, so that the screen plate 35 is not damaged during separation, the separation effect is poor, and after the pretreatment is completed, the sludge falls into the sieve barrel 31 through the electromagnetic induction valve 9 inside the transition port 6, and the electric cam 36 is started. The electric cam 36 on both sides has different lengths, which pushes the top and bottom screen plates 35 and squeezes the telescopic support 33 and the spring 34 inside the telescopic support 33 and the support ring 32 between the screen plates 35, and in the process of rotating the electric cam 36, the spring 34 accumulates elastic potential energy and rebounds to drive the screen plate 35 to vibrate, and the gravity of the sludge falling can be irregularly multi-stage sieved to complete the separation of impurities, and finally the sludge is collected from the bottom discharge port 7, and other impurities can be recycled by opening the door plate in front of the separation outer box 1 and taking out the sieve barrel 31.

[0042] The above is only a preferred embodiment of the present application, and is not intended to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principles of the present application shall be included in the protection scope of the present application.
