[0034] A plurality of double parallel connection devices 10 are arranged on the side of the lower pump body 8, each double parallel connection device 10 is connected to a connecting pipe 11 through a second bolt, and the connecting pipe 11 is connected to a parallel pump through a second connecting flange 12. The parallel pump includes a parallel pump compressed air injection port 13, a parallel pump outer pump body 14, a parallel pump air inlet 15, a parallel pump pump body 16, a parallel pump air inlet buffer chamber 17 and a parallel pump lower pump body 18.

[0035] The double parallel connection device 10 and the lower pump body 8 are welded to form a whole. The ends of the double parallel connection devices 10 on both sides of the lower pump body 8 are welded with the first connection flange and form a whole with the first connection flange. The end of the connecting pipe 11 is connected to the second flange 12 and forms a whole with the second flange 12; the connecting pipe 11 is connected to the double parallel connection device 10 by bolts.

[0038] A pulse water jet nozzle is added to the lower part of the suction lift pump to achieve hydraulic crushing and bottom fluidization enhancement. By introducing the pulse water jet nozzle, the present invention utilizes the hydraulic impact effect in the process of crushing granular materials, thereby significantly improving the crushing efficiency. At the same time, the water jet nozzle can also improve the fluidization state of the bottom particles, further enhancing the suction efficiency.

[0039] In order to make the above-mentioned objects, features and advantages of the present invention more clearly understood, the following is a brief description of the present invention in conjunction with the attached drawings. Figures 1 to 14 The technical solution of the present invention is further described in detail as follows:

[0040] like Figure 3 and Figure 4 As shown, the upper pump body 1 is the top component of the entire suction lift pump, which is connected to the lifting pipeline by bolts to achieve material transportation. Figure 5 As shown, the first connecting flange 2 is tightly connected to the lower part of the upper pump body 1, and the entire structure is firmly supported by bolt connection. Figure 6 and Figure 7 As shown, the injection device 3 is located below the first connecting flange 2, wherein the injection device 3 is provided with a plurality of injection ports 4, which are used to inject compressed air into the main air intake chamber 5. The main air intake chamber 5 guides the compressed air to the middle pump body 6, thereby realizing the continuous flow of gas. Figure 8 As shown, the middle pump body 6 introduces compressed air through the main air inlet 7 on the middle pump body 6, so that the gas diffuses in the chamber to achieve the effect of lifting the material. Fig. 9 As shown, the lower pump body 8 is located below the middle pump body and is connected to the middle pump body 6 by bolts 9, forming the lower part of the entire suction lift pump.

[0041] Fig.10 and Fig.11 Combination Figure 2The double parallel connection device 10 is tightly connected to the lower pump body 8 by welding to form a solid integral structure. The connecting pipe 11 is connected to the end of the double parallel connection device 10, and the end of the connecting pipe 11 is connected to the third connecting flange 12 to ensure the firmness of the connection. The parallel pump is a key component connected to the connecting pipe 11. The parallel pump includes a parallel pump compressed air injection port 13, a parallel pump outer pump body 14, a parallel pump air inlet 15, a parallel pump body 16, a parallel pump air inlet buffer chamber 17 and a parallel pump lower pump body 18. The pulse water jet crushing device 20 is welded to the parallel pump outer pump body 14 through a fixed crossbeam 19, so that the arrangement of the pulse water jet injection port can maximize the crushing efficiency.

[0042] Specific working principle: When using the suction lift pump of the present invention for operations such as silting, dredging and marine mining, first, through appropriate control, the compressed air is guided into the upper part of the suction lift pump (upper pump body 1, middle pump body 6), and enters the main air intake chamber 5 through the injection port 4 of the injection device 3. Then, the gas diffuses in the middle pump body to form a continuous gas flow. Fig.12 , Fig.13 and Fig.14 In the dual parallel crushing device 20 in the lower part, the role of the parallel pump in the present invention is mainly to transport the slurry and ensure that the material can be efficiently transported in the entire suction and lifting pump. The pulse water jet nozzle is another key component. While realizing the high-pressure water pulse injection, it also has a certain crushing effect. High-pressure water is injected from the upper nozzle 201 and then ejected through the lower nozzle 203. By interacting with the material, the crushing effect on the material is achieved. When the parallel suction and lifting pump of the present invention is used for operation, the compressed air is guided into the upper part of the parallel pump, enters the annular auxiliary air intake buffer chamber 202 through the air inlet of the parallel pump, and then is uniformly output through the compressed air injection port 13 of the parallel pump. Such a structural layout and design ensure the stable flow of gas and provide reliable power for the next step of material transportation. At the same time, the bolt holes for installing the suction port are reserved on the lower pump body of the parallel pump, which is convenient for connecting different suction ports under different working conditions.

[0043] The suction lift pump system of the present invention mainly includes two key innovations: first, a plurality of double parallel connection devices 10 are arranged on the side of the lower pump body 8, each of which is connected to two connecting pipes 11 through a second bolt, and the connecting pipe 11 is connected to a parallel pump through a second connecting flange 12. This technology adopts a parallel configuration of multiple small air lift heads to expand the scope of construction operations. By arranging multiple air lift heads in parallel in the system, the system can more flexibly adapt to the operation requirements of different depths and positions, thereby effectively improving the coverage and efficiency of dredging, dredging and mining operations. Second, a fixed crossbeam 19 is arranged on the outer pump body 14 of the parallel pump, and a pulse water jet crushing device 20 is connected to the fixed crossbeam 19. The pulse water jet crushing device 20 includes an upper nozzle 201, a pulse cavity 202, and a lower nozzle 203. A pulse water jet nozzle is added to the air lift head to achieve hydraulic crushing and bottom fluidization enhancement. By introducing a pulse water jet nozzle, the system utilizes the hydraulic impact effect in the process of crushing granular materials, thereby significantly improving the crushing efficiency. At the same time, the water jet nozzle can also improve the fluidization state of the bottom particles and further enhance the suction efficiency.

[0044] The synergy of the entire system makes the pneumatic lifting, material conveying and crushing process efficient and smooth, greatly improving the operating efficiency. The advantages of this invention are compact structure and significant collaborative operation effect, which is suitable for a variety of silt removal, dredging and marine mining operations. In actual use, the number of air lift heads can be appropriately adjusted according to the operating depth and location requirements to meet the requirements of different silt removal, dredging and mining tasks. The use of pulsed water jet nozzles will improve the crushing efficiency, while improving the fluidization state of the bottom particles and further enhancing the suction efficiency.

[0045] In summary, although the present invention has been disclosed as above in terms of preferred embodiments, the above preferred embodiments are not intended to limit the present invention. A person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined in the claims.
