Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline dredging, and particularly relates to a dredging device for a leachate drainage system. Background Art

[0002] The domestic waste landfilled in a landfill site will produce a large amount of high-concentration organic wastewater, known as landfill leachate, due to its own water content, atmospheric precipitation, storage and fermentation, etc. Usually, it needs to be centrally collected and disposed of uniformly. After the leachate collection and drainage pipeline system is used for a long time, there is a large amount of hardened silt and high-salt crystallization inside the pipeline. If it is not cleaned in time, it will cause poor drainage of leachate, and in severe cases, it will even cause the leachate to backfill into the garbage heap, resulting in an increase in the liquid level inside the heap and the sliding of the heap body.

[0003] In the prior art, the pipeline dredging work of the leachate drainage system is usually carried out by manually sawing and separating the drainage pipes, knocking and vibrating the crystallization blocks inside the pipes section by section, and then flushing with running water to remove the residual impurities. This method not only consumes a large amount of manpower and material resources, but also the way of sawing and separating the drainage pipes section by section not only hinders the normal function of the drainage system, but also increases the secondary connection cost and maintenance cost of the drainage pipes, and reduces the service life of the pipes. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a dredging device for a leachate drainage system to overcome the defects of the prior art. The dredging operation can be realized by removing the drainage pipe at the original flange connection of the pipeline, which can effectively remove the specific crystallization silt in the leachate drainage pipeline, and at the same time can avoid excessive cutting of the leachate drainage pipe, greatly improving the dredging efficiency.

[0005] The purpose of the utility model is achieved by the following technical solutions:

[0006] A dredging device for a leachate drainage system includes a high-pressure water pipe, which is connected to an external high-pressure water source. A first water outlet device and a second water outlet device are also connected to the high-pressure water pipe. A mud scraping assembly is arranged between the first water outlet device and the second water outlet device. The mud scraping assembly includes a rotating structure sleeved on the high-pressure water pipe and mud scraping blades arranged on the outside of the rotating structure.

[0007] Among them, the first water outlet device has a plurality of first water outlets. The second water outlet device is provided with a second water outlet and a third water outlet. The water outlet directions of the first water outlets and the second water outlets are respectively located on both sides of the mud scraping assembly. The third water outlet discharges water along the radial direction of the high-pressure water pipe, and the water discharged from the third water outlet contacts the rotating structure.

[0008] In one embodiment, the rotating structure includes a threaded pipe sleeved on the high-pressure water pipe. The inner diameter of the threaded pipe is larger than the diameter of the high-pressure water pipe. A plurality of rotating blades are sequentially arranged on the threaded pipe along its circumferential direction. The rotating blades extend obliquely and form an acute angle with the high-pressure water pipe. The water discharged from the third water outlet contacts the rotating blades.

[0009] In one embodiment, it further includes a limiting member fixed on the high-pressure water pipe, and the limiting member is arranged between the first water outlet device and the sludge scraping assembly.

[0010] In one embodiment, the limiting member is a double-ring ball bearing, the inner ring of which is helically fixed on the high-pressure water pipe, and the ball groove between its inner ring and outer ring corresponds to the convex point part of the rotating structure.

[0011] In one embodiment, the sludge scraping blade includes a straight plate segment connected to the rotating structure and an arc plate segment arranged at the top of the straight plate segment. The arc plate segment bends towards the direction close to the rotating blade.

Detailed implementation manners

[0025] The present utility model will be further described below in conjunction with the drawings.

[0026] The present utility model provides a silt - cleaning device for a leachate drainage system, as Figure 1 and Figure 2 shown, which includes a high - pressure water pipe 1. The high - pressure water pipe 1 is connected to an external high - pressure water source. The high - pressure water pipe 1 is also connected with a first water outlet device 2 and a second water outlet device 5. A sludge scraping assembly 4 is arranged between the first water outlet device 2 and the second water outlet device 5. The sludge scraping assembly 4 includes a rotating structure 401 sleeved on the high - pressure water pipe 1 and a sludge scraping blade 402 arranged on the outside of the rotating structure 401;

[0027] Among them, the first water outlet device 2 has a plurality of first water outlets 201 with the same water outlet direction. The water outlet direction of the first water outlets 201 is parallel to the axial direction of the high - pressure water pipe 1. The second water outlet device 5 is provided with a second water outlet (501) and a third water outlet 502. The water outlet direction of the second water outlet 501 is opposite to the water outlet direction of the first water outlets 201. The third water outlet 502 discharges water along the radial direction of the high - pressure water pipe 1, and the water discharged from the third water outlet 502 contacts the rotating structure 401;

[0028] It should be noted that the dredging device provided in this embodiment softens the silt by the water discharged from the second water outlet 501, drives the sludge scraping assembly 4 to rotate by the water discharged from the third water outlet 502, and the first water outlet device 2 communicated with the high-pressure water source provides thrust to discharge the loosened and fallen silt backward through the high-pressure water flow. The water discharged from the first water outlet 201 is opposite to the water discharged from the second water outlet 501. The water discharged from the first water outlet 201 drives the dredging device to move in the drainage pipe. That is, through this device, the dredging device can be placed in the drainage pipe at the original flange connection of the pipe, and the high-pressure water source can be started to carry out the dredging operation, which can effectively remove the specific crystalline silt in the leachate drainage pipe, and at the same time can avoid excessive cutting of the leachate drainage pipe, greatly improving the dredging efficiency;

[0029] In one embodiment, as Figure 3 shown, the third water outlet 502 on the second water outlet device 5 discharges water horizontally in this view, so as to better drive the rotating structure 401;

[0030] Specifically, the rotating structure 401 includes a threaded pipe sleeved on the high-pressure water pipe 1. The inner diameter of the threaded pipe is larger than the pipe diameter of the high-pressure water pipe 1. A plurality of rotating blades are sequentially arranged along the circumferential direction of the threaded pipe. The rotating blades extend obliquely and the included angle between the rotating blades and the high-pressure water pipe 1 is an acute angle. The water discharged from the third water outlet 502 contacts the rotating blades. The third water outlet 502 is opened on one side of the second water outlet device 5. That is, a threaded pipe slightly larger than the size of the high-pressure water pipe 1 can be sleeved on the high-pressure water pipe 1, so that under the action of the high-pressure water source, the rotating blades on the threaded pipe can rotate along the high-pressure water pipe 1, and then drive the sludge scraping blade 402 outside the rotating structure 401 to scrape the hard-packed silt and high-salt crystals attached to the pipe wall;

[0031] In one embodiment, as Figure 1 shown, the dredging device further includes a limiting member fixed on the high-pressure water pipe 1, and the limiting member is arranged between the first water outlet device 2 and the sludge scraping assembly 4;

[0032] Specifically, the limiting member is a double-ring ball bearing, the inner ring of which is helically fixed on the high-pressure water pipe 1, and the ball groove between the inner ring and the outer ring corresponds to the convex point portion 403 of the rotating structure 401;

[0033] It should be noted that by using the double-ring ball bearing provided on the high-pressure water pipe 1, the ball grooves thereof are corresponding to the bump parts 403 of the rotating structure 401, that is, the limiting member and the rotating structure 401 are not connected in the natural state, which is convenient for disassembly and rotation. When the rotating structure 401 is displaced under the impact of the high-pressure water source, the bump parts 403 thereon gradually approach the ball grooves of the limiting member and directly contact the ball grooves. Since the limiting member is fixed on the high-pressure water pipe 1, the position of the rotating structure 401 is limited, and its rotation is not affected, so as to avoid affecting the driving effect of the third water outlet 502 on the rotating structure 401;

[0034] In one embodiment, as Figure 1 shown, the mud scraping blade 402 includes a straight plate section connected to the rotating structure 401 and an arc plate section provided at the top of the straight plate section, and the arc plate section is bent towards the direction close to the rotating blade;

[0035] It should be noted that the arc plate section structure at the tip of the mud scraping blade 402 increases the contact area with the silt on the one hand and reduces the damage to the inner wall of the drainage pipe on the other hand;

[0036] In one embodiment, as Figure 1 shown, both the first water outlet device 2 and the second water outlet device 5 are mouse head nozzles communicated with the high-pressure water pipe 1. One end of the high-pressure water pipe 1 is communicated with an external high-pressure water source, and the second water outlet device 5 is communicated with the other end of the high-pressure water pipe 1;

[0037] In one embodiment, both the rotating structure 401 and the mud scraping blade 402 are made of modified plastic material;

[0038] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "bottom", "top", "front", "rear", "inner", "outer", "left", "right", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model.

[0039] Although the present utility model has been described herein with reference to specific embodiments, it should be understood that these embodiments are merely examples of the principles and applications of the present utility model. Therefore, it should be understood that many modifications can be made to the exemplary embodiments, and other arrangements can be designed, as long as they do not deviate from the spirit and scope of the present utility model as defined by the appended claims. It should be understood that the different dependent claims and the features described herein can be combined in a manner different from that described in the original claims. It should also be understood that the features described in connection with a single embodiment can be used in other described embodiments.
