[0040] The utility model embodiment provides a kind of multi-power dredging device 100.Therein dredging device 100 for example can be applied to dredging device field, such as for ditch well, can solve the problem that existing bottom mud suction device is difficult to work in some special scenes, such as rural sewage treatment facilities.

[0041] For the convenience of description, in the following, the dredging device 100 is taken as an example to be applied to rural sewage treatment facilities for illustration.It can be understood that it is only a specific application scenario, but it does not mean limitation, and it can still be used in various environments that need dredging.

[0042] In the preferred embodiment, Figure 1 It is the overall schematic diagram of the dredging device 100 according to an embodiment of the utility model.The dredging device 100 provided by the utility model embodiment includes an air compressor 110, a suction dredging pump 120, a suction dredging lifting mechanism, a free flow pipeline 140 and a pump pressure flow pipeline 150.

[0043] Among them, the air compressor 110 and the suction dredging pump 120 are important components of the present application, used to provide different power sources for suction of silt.The suction dredging lifting mechanism, as a component directly contacting the unit to be dredged, is used to suction silt.The free flow pipeline 140 and the pump pressure flow pipeline 150 are respectively used as intermediate silt transport pipelines corresponding to the air compressor 110 and the suction dredging pump 120, for transferring the silt suctioned up.

[0044] Specifically, regarding the air compressor 110 and the suction dredging pump 120, they can respectively adopt existing equipment.Meanwhile, since the tools commonly used by sewage treatment facility maintenance personnel in reality generally include the air compressor 110 and the suction dredging pump 120, the dredging device 100 according to the embodiment of the utility model also has the advantages of flexible assembly on demand and low assembly cost.

[0045] At least one suction dredging lifting mechanism for extending into the unit to be dredged, wherein the unit to be dredged can be, for example, a ditch well, a bottom mud inspection well or a ditch and the like.According to the number of units to be dredged that need to be dredged simultaneously, the number of suction dredging lifting mechanisms is matched.For example, referring to Figure 1The to-be-dredged unit can include a first to-be-dredged unit 310 and a second to-be-dredged unit 320. The first to-be-dredged unit 310 can be a deep-pool dredging unit (relatively deep pool when the pool water depth is generally 2.0 m or more). The second to-be-dredged unit 320 can be a shallow-pool dredging unit (relatively shallow pool when the pool water depth is generally less than 2.0 m). Correspondingly, two suction dredging and upflow mechanisms are configured. The suction ports 130 of the two suction dredging and upflow mechanisms are respectively connected in parallel between the air source pipelines 111 and the inlets thereof can be connected to the air compressor 110 through the same air source main pipeline 112.

[0046] Further, each suction dredging and upflow mechanism can include a suction port 130, an air source pipeline 111, and a suction and upflow pipeline 131. Each suction dredging and upflow mechanism includes at least one suction port 130, such as one suction port 130, two suction ports 130, or other numbers of suction ports 130, which are reasonably arranged according to actual needs. For example, referring to Figure 2 , Figure 2 Fig. 1 is a schematic diagram of a single-pipe suction dredging and upflow mechanism and a multi-pipe suction dredging and upflow mechanism in the dredging device 100 according to an embodiment of the present application. In the figure, Figure 2 (a) of Fig. 1 is a single-pipe suction dredging and upflow mechanism, that is, including one suction port 130. Figure 2 (b) of Fig. 1 is a multi-pipe suction dredging and upflow mechanism, which is shown as a two-pipe suction dredging and upflow mechanism in the figure, that is, including two suction ports 130. At this time, the suction and upflow pipelines 131 connected in parallel between the two suction ports 130 are respectively connected. In order to improve the suction effect of the suction port 130, the suction port 130 can be a variable-diameter horn type suction port with a small top and a large bottom. The top outlet of each suction port 130 is respectively connected to the air source pipeline 111 and the suction and upflow pipeline 131 arranged in parallel. The air source pipeline 111 is connected to the air compressor 110.

[0047] The free flow pipeline 140 and the pump pressure flow pipeline 150 connected in parallel at the end of the suction and upflow pipeline 131. The suction pump 120 is installed on the pump pressure flow pipeline 150. The outlets at the other ends of the free flow pipeline 140 and the pump pressure flow pipeline 150 are used to be connected to the sludge collecting unit 200. For example, the outlets at the other ends of the free flow pipeline 140 and the pump pressure flow pipeline 150 can be connected to the same sludge outlet main pipeline 162. Through the same sludge outlet main pipeline 162, the sludge collecting unit 200 is connected. The sludge collecting unit 200 can adopt the prior art device, and is not the invention of the present application, which will not be described in detail here.

[0048] The air source pipeline 111 can be provided with an air valve 113 for opening and closing or adjusting the air lifting flow. The suction lifting pipeline 131, the free flow pipeline 140 and the pump pressure flow pipeline 150 can be respectively provided with a pipeline valve 132 for adjusting the suction flow.

[0049] It can be understood that in the illustrated embodiment, the suction lifting pipeline 131, the free flow pipeline 140 and the pump pressure flow pipeline 150 are respectively provided with corresponding pipeline valves 132, or part of the suction lifting pipeline 131, the free flow pipeline 140 and the pump pressure flow pipeline 150 can be provided with pipeline valves 132.

[0050] Based on the above scheme, the silt pumping device 100 of the embodiment has two working modes of air lifting silt pumping work using air provided by the air compressor 110 as a power source and silt pumping work using the silt suction pump 120 as a power source, which can be used separately or jointly assembled and configured. It can be transported by a mobile vehicle and assembled at the use site, or directly installed at the use site. If the use site involves the bottom of two places such as the first silt cleaning unit 310 and the second silt cleaning unit 320 needing to be cleaned, the same set of silt suction lifting mechanisms can be used to perform silt pumping work in sequence (for example, after the first silt cleaning unit 310 is pumped, the second silt cleaning unit 320 is pumped), or two silt suction lifting mechanisms are independently arranged at each point to perform silt pumping work at the same time, Figure 1 The middle is an example of two-point synchronous silt pumping.

[0051] According to the silt pumping device 100 of the utility model, the air lifting silt pumping function is realized through the air compressor 110, the air source pipeline 111, the suction lifting pipeline 131 and the free flow pipeline 140, and the silt suction pump pumping function is realized through the silt suction pump 120, the suction lifting pipeline 131 and the pump pressure flow pipeline 150. According to different silt pumping environments, the air compressor 110 and the silt suction pump 120 can be freely assembled to meet the corresponding silt pumping requirements, and the structure is simple and convenient to carry.

[0052] In the preferred embodiment, in order to observe the suction effect in time, the free flow pipeline 140 and the pump pressure flow pipeline 150 can each be provided with a transparent window pipe 161. The transparent window pipe 161 can be a non-metal pipe, such as a transparent UPVC hard pipe or a steel wire flexible pipe, which is convenient for observing whether the fluid is normally lifted.

[0053] Similarly, the suction lifting pipeline 131, the free flow pipeline 140 and the pump pressure flow pipeline 150 can be made of non-metal pipes or metal pipes, and UPVC non-metal hard pipes can be preferred.

[0054] In order to realize the normal work of the air compressor 110 and the suction pump 120, the dredging device 100 can further comprise a power supply device electrically connected to the air compressor 110 and the suction pump 120, for providing power.

[0055] For example, the power can be supplied by the external power distribution box 171, or by the solar photovoltaic power generation and energy storage assembly 172, or by the solar photovoltaic power generation and energy storage assembly 172 and the external power distribution box 171 as a complementary dual power supply, and the power is provided to the air compressor 110 and the suction pump 120 through a cable.

[0056] In the illustrated embodiment, in order to realize quick disassembly and quick assembly of the pipeline, at least one quick connector 180 (for example, a flexible joint) can be arranged in the suction riser pipeline 131, the free flow pipeline 140, and the pump pressure flow pipeline 150 or part of the pipelines. For example, one quick connector 180, two quick connectors 180, or other reasonable number of quick connectors 180 can be arranged in the corresponding pipeline according to the needs. When the first unit to be dredged 310 and / or the second unit to be dredged 320 is deep enough, multiple quick connectors 180 and multiple suction riser pipelines 131 can be used in combination. A single suction riser pipeline 131 can be configured with a length of 1-1.5 m, so that it can be carried by a small car or a transport vehicle after disassembly.

[0057] It can be understood that the mud outlet main pipe 162 can also be provided with a quick connector 180 to realize quick disassembly and assembly.

[0058] The working process of the dredging device 100 according to the present embodiment will be described below based on the structure shown in the figure: Figure 1

[0059] ​The working process of the air compressor 110 as a power source: the gas generated by the air compressor 110 is transported outward through the gas source main pipe 112 (the inner diameter of the pipe is generally 6-15 mm) to the air pressure gas source, and then enters the first sludge cleaning unit 310 through the corresponding gas source pipeline 111 at the communication part of the gas source pipeline 111 above the corresponding sludge suction port 130 and the suction lifting pipeline 131, and then enters the suction lifting pipeline 131. At the same time, the other gas source pipeline 111 can enter the second sludge cleaning unit 320 at the communication part of the gas source pipeline 111 above the corresponding sludge suction port 130 and the suction lifting pipeline 131, and then enter the corresponding suction lifting pipeline 131. The lower diameter of the sludge suction port 130 can be 2-3 times larger than the upper diameter, for example, the upper diameter can be DN32-DN65 mm, and the lower diameter can be DN100-DN180 mm. Because the resistance of the gas passing upward in the suction lifting pipeline 131 is smaller than the resistance of the gas passing downward, the gas moves to the upper end of the suction lifting pipeline 131. In the process of upward movement of the gas, the sludge at the bottom of the corresponding sludge suction port 130 is carried out by the suction lifting pipeline 131, and the gas-liquid mixture carrying the sludge enters the free flow pipeline 140, and finally flows into the sludge collection unit 200. The free flow pipeline 140 is mainly provided with a transparent window pipe 161, a quick connector 180 (the number of which is adjusted according to the need), and a pipeline valve 132. When the air compressor 110 is working, the gas valve 113 installed on the corresponding gas source pipeline 111 can be used to open, close or adjust the gas lifting flow. If the bottom area of the sludge suction object of the first sludge cleaning unit 310 and the second sludge cleaning unit 320 is too large, multiple sludge suction ports 130 can be used to work to improve the working efficiency. During the sludge suction process, the suction flow of the suction lifting pipeline 131 and the whole can be adjusted through the pipeline valve 132, and the suction effect of the bottom sludge can be observed through the transparent window pipe 161.

[0060] The working process of the air compressor 110 as a power source: the gas generated by the air compressor 110 is transported outward through the gas source main pipe 112 (the inner diameter of the pipe is generally 6-15 mm) to the air pressure gas source, and then enters the first sludge cleaning unit 310 through the corresponding gas source pipeline 111 at the communication part of the gas source pipeline 111 above the corresponding sludge suction port 130 and the suction lifting pipeline 131, and then enters the suction lifting pipeline 131. At the same time, the other gas source pipeline 111 can enter the second sludge cleaning unit 320 at the communication part of the gas source pipeline 111 above the corresponding sludge suction port 130 and the suction lifting pipeline 131, and then enter the corresponding suction lifting pipeline 131. The lower diameter of the sludge suction port 130 can be 2-3 times larger than the upper diameter, for example, the upper diameter can be DN32-DN65 mm, and the lower diameter can be DN100-DN180 mm. Because the resistance of the gas passing upward in the suction lifting pipeline 131 is smaller than the resistance of the gas passing downward, the gas moves to the upper end of the suction lifting pipeline 131. In the process of upward movement of the gas, the sludge at the bottom of the corresponding sludge suction port 130 is carried out by the suction lifting pipeline 131, and the gas-liquid mixture carrying the sludge enters the free flow pipeline 140, and finally flows into the sludge collection unit 200. The free flow pipeline 140 is mainly provided with a transparent window pipe 161, a quick connector 180 (the number of which is adjusted according to the need), and a pipeline valve 132. When the air compressor 110 is working, the gas valve 113 installed on the corresponding gas source pipeline 111 can be used to open, close or adjust the gas lifting flow. If the bottom area of the sludge suction object of the first sludge cleaning unit 310 and the second sludge cleaning unit 320 is too large, multiple sludge suction ports 130 can be used to work to improve the working efficiency. During the sludge suction process, the suction flow of the suction lifting pipeline 131 and the whole can be adjusted through the pipeline valve 132, and the suction effect of the bottom sludge can be observed through the transparent window pipe 161.

[0061] In summary, according to the silt pumping device 100 of the utility model, there are complementary dual power supply of electricity and light to meet the emergency dredging scene under the power-off state, realize the low-carbon operation of green solar clean energy utilization. Through the independent or combined power operation mode of gas stripping and pumping, the efficient operation of multiple scenes can be met. Through the detachable live joint splicing pipeline, two installation and assembly methods of mobile vehicle portable transportation and in-situ fixation installation can be met, and it can adapt to different pool depths (well depths), especially deep well dredging. Through the single-pipe or multi-pipe type silt pumping and lifting mechanism, the coordinated and synchronous silt pumping operation of different area points in different pools (wells) and in the same pool (well) can be met. Through the segmented multi-pipeline valve 132, the balance adjustment and regulation of the silt pumping amount can be achieved. Through the transparent window pipe 161, the visual observation of the sensory effect of the silt pumping sludge can be met.
