The silting of urban ditches and river channels increasingly affects the normal play of various functions such as flood control, flood drainage, water supply, navigation and the like. In order to recover the normal functions of the urban ditch network and the river channel and promote the rapid and continuous development of the economic society, the dredging engineering of the urban ditch network and the river channel is required. The accumulation of sludge in urban ditch nets and river channels is reduced, and the aims of 'clear water, smooth river, green bank and beautiful landscape' are achieved.
The existing dredging equipment has various types, but most of dredging equipment generally comprises two structural parts, namely sludge extraction and sludge storage and transportation, wherein the sludge extraction is generally carried out through a sludge pump, and the sludge storage and transportation are realized through a sludge storage tank. When the sludge pump works, solid matters such as silt or impurities are not distinguished, but the solid matters and sewage are simultaneously pumped into the sludge storage tank, so that the sludge storage tank is often and quickly filled with the solid matters and water, once the sludge storage tank is filled, the sludge storage tank needs to be stopped to unload, and the dredging efficiency is seriously reduced.
Disclosure of Invention
The invention aims to provide a silt removing device for water conservancy construction, which not only can be used for cleaning silt, but also can be used for classifying and distinguishing solid and liquid in a silt storage tank so as to improve the silt removing efficiency.

a sludge separation structure is arranged in the sludge storage tank, and comprises a frame, a screen, a funnel and a drainage hose; the outer part of the frame is in up-and-down sliding fit with the inner side walls of the periphery of the sludge storage box, and the screen is fully paved and fixedly connected on the frame; the frame and the screen are both positioned above the inlet of the sludge storage tank; the funnel is fixed on the screen or the frame; the large opening at the upper end of the funnel protrudes upwards out of the upper surface of the screen, and the small opening at the lower end of the funnel is communicated with a drainage hose; the bottom of the sludge storage box is provided with a connecting hole, and the drainage hose extends to the outside of the sludge storage box through the connecting hole; the drainage hose and the connecting hole are sealed through a rubber sealing ring.
Further: and a fine steel wire mesh is wrapped outside the drainage hose.
Further: and a filter cloth is fixedly paved at the large opening at the upper end of the funnel.
Further: a sludge pumping hose is arranged inside the sludge storage tank; one end of the sludge pumping hose is communicated with the inlet, and the other end of the sludge pumping hose floats freely; the silt pumping hose is positioned below the screen mesh.
Further: the end of the silt pumping hose far away from the inlet is of a horn-shaped amplification structure.
The beneficial effect of this scheme: the invention discloses a silt discharging device for water conservancy construction, which is mainly improved aiming at a sludge storage tank in the prior art, so that solid matters and sewage pumped by a sludge pumping pump can be separated under the condition of no external driving force when the sludge storage tank works, and the separated sewage flows back to a river channel, so that the sludge storage tank can contain more solid matters and does not need to be stopped frequently; on the other hand, the waste of water sources in the river channel can be avoided.
The silt removing device in the scheme is realized by the following structure: the sludge separation structure is arranged in the sludge storage box and comprises a frame, a screen, a funnel and a drainage hose. The frame is used for fixing the screen cloth, guarantees simultaneously that the screen cloth can reciprocate along the lateral wall of storing up mud case. The funnel is then used for guaranteeing that sewage can be collected to the drainage hose in. The reason why the drain hose is used in this case is that the drain hose needs to be curled, contracted or extended according to the up-down position of the mesh, and the drain hose needs to have a certain contraction ductility, so that it cannot be replaced by another pipe. The silt separation structure who comprises frame, screen cloth, funnel and drainage hose has then guaranteed that solid and sewage can separate in storing up the mud case to sewage can flow back to the river course through drainage hose.
In order to further ensure that the drainage hose is not shrunk or blocked and ensure that the silt pumping pipeline is not blocked, the scheme also optimizes the large opening at the upper end of the funnel, and is favorable for further ensuring that the silt separation structure in the scheme can better work by additionally arranging the filter cloth and wrapping a fine steel wire mesh and the like outside the drainage hose.

Detailed Description
The invention is further illustrated by the following examples in conjunction with the accompanying drawings:
as shown in figures 1 and 2, the sludge discharge device for water conservancy construction disclosed by the invention comprises a sludge extraction structure and a sludge storage structure. Silt extraction structure includes takes out silt pump 4 and takes out silt pipeline 3, and silt storage structure includes frame 2 and the open storage mud case 1 in top. The bottom of the sludge storage tank 1 is provided with an inlet 11, the inlet 11 is communicated with a sludge pumping pipeline 3, the sludge pumping pipeline 3 is communicated with a sludge pumping pump 4, and the sludge pumping pump 4 pumps solids and sewage through the sludge pumping pipeline 3 and conveys the solids and the sewage to the sludge storage tank 1 through the inlet 11. In this scheme, be provided with silt isolating construction in the inside of storing up mud case 1. The sludge separating structure includes a frame 5, a mesh 6, a hopper 7, and a drain hose 8.
As shown in fig. 2, the frame 5 is in up-and-down sliding fit with the inner side wall of the mud storage tank 1, and the frame 5 can slide up and down along the inner side wall of the mud storage tank 1. The screen 6 is fully laid and is fixedly connected to the frame 5 by bolts. The frame 5 and the screen 6 are both located above the inlet 11 of the sludge storage tank 1. The funnel 7 is also fixed to the screen 6 by welding or may be fixedly attached to the frame 5. However, the upper end large opening of the funnel 7 is directed vertically upward, and the end surface of the upper end large opening of the funnel 7 projects upward beyond the screen 6. And a small opening at the lower end of the funnel 7 is communicated with a drain hose 8. In the present case, connecting hole 12 has still been seted up to the bottom of storing up mud case 1, and drainage hose 8 extends to the outside of storing up mud case 1 through connecting hole 12, and seals through rubber seal between drainage hose 8 and the connecting hole 12 and handle.
The implementation principle of the scheme is as follows: as shown in fig. 1 and 2, when there is no sludge inside the mud storage tank 1, the frame 5 and the mesh 6 slide down to the bottom of the mud storage tank 1 by gravity, and the drain hose 8, which is located inside the mud storage tank 1 at this time, is in a curled and compressed state. When the sludge pumping pump 4 pumps and conveys solid and sewage into the sludge storage tank 1 continuously through the sludge pumping pipeline 3, the solid and the sewage continuously extrude the frame 5 and the screen 6 upwards, and the frame 5 and the screen 6 are driven to move upwards slowly. However, due to the filtering insulation of the screen 6, the solid matter cannot pass through the screen 6, and the sewage can pass through the screen 6, thereby causing the water level in the sludge storage tank 1 to continuously rise. When the water surface in the sludge storage tank 1 spreads over the large opening at the upper end of the funnel 7, sewage flows back downwards into the drainage hose 8 through the funnel 7 and is discharged to the outside of the sludge storage tank 1 through the drainage hose 8. In actual operation, the drainage hose 8 located outside the sludge storage tank 1 can be extended into the river channel to promote the backflow of the sewage. But the returned sewage has been physically filtered through the screen 6 at this time. Thus, the end result of the above embodiment: all of the finally stored sludge in the sludge storage tank 1 are solid matters and cannot be filled with sewage, and all the sewage flows back to the river channel through the drainage hose 8.
During the actual operation, for preventing that drainage hose 8 from receiving the extrusion of solid, can be in 8 outside parcel one deck fine steel wire nets of drainage hose, just so can prevent that the solid from with 8 extrusion deformations of drainage hose, and then lead to drainage hose 8 to be blockked up. In order to prevent small particle impurities from entering the drain hose 8, a layer of filter cloth is laid at the large opening at the upper end of the funnel 7. Because in practice, the filtering holes of the screen 6 cannot be too small, otherwise the filtering of the sewage is easily affected, the sewage flowing back through the funnel 7 is not very clean water, and still contains some small micro-particles, and the filtering cloth is additionally arranged on the large opening at the upper end of the funnel 7, so that the problem of blockage is effectively solved.
As shown in fig. 2, the sludge pumping pipe 3 is connected to the sludge storage tank 1 through the inlet 11, and when a large solid is encountered while continuously transporting a solid and sewage into the sludge storage tank 1, there may be a bad result that the inlet 11 is blocked by the solid. Therefore, in the optimized embodiment, a silt pumping hose 9 is additionally arranged inside the sludge storage tank 1, one end of the silt pumping hose 9 is communicated with the inlet 11, the other end of the silt pumping hose 9 floats freely, and the end of the silt pumping hose 9 far away from the inlet 11 is of a horn-shaped enlarged structure. When solid and sewage are continuously input into the sludge storage tank 1 through the sludge pumping hose 9, the sludge pumping pipeline 3 is used for pumping the solid and sewage through the sludge pumping hose 9. The silt pumping hose 9 is in a free state in the silt storage tank 1, when solid matters are accumulated on the silt pumping hose 9, the silt pumping hose 9 gets rid of the solid matters through pumping force of the silt pumping pump 4, and meanwhile, the silt pumping hose 9 also gradually rises along with the screen 6, so that the silt pumping pipeline 3 is effectively prevented from being blocked by the solid matters.
The above description is only exemplary of the present invention and should not be taken as limiting, and any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
