[0030] Refer to Figures 1 to 3 , the bottom pile sludge cleaning reverse circulation device of the embodiment of the present utility model includes a slag discharge pipe 100 and an air duct 200. The water suction end 101 of the slag discharge pipe 100 extends below the liquid level or is between the liquid level surface 0 to 3 cm, and the slag discharge end 102 extends to the sedimentation tank; the air outlet end 201 of the air duct 200 is connected to the side wall of the water suction end 101 of the slag discharge pipe 100 and is communicated with the slag discharge pipe 100, and the air inlet end 202 is connected to an air compressor. Among them, the air outlet direction of the air outlet end 201 is inclined upward towards the slag discharge pipe 100.

[0031] In actual use, high-pressure air is input into the air duct 200 through an air compressor. The high-pressure air quickly enters the slag discharge pipe 100 through the air outlet end 201, forming a rapidly flowing air current in the slag discharge pipe 100 and creating a pressure difference inside the slag discharge pipe 100 (the air pressure outside the slag discharge pipe 100 is higher than the air pressure inside the slag discharge pipe 100). This can actively bring the mud, sediment, and rock debris in the pile pit into the slag discharge pipe 100 and finally transport them to the sedimentation tank to achieve the purpose of quickly cleaning the pile pit.

[0032] Among them, as Embodiment 1 of the present utility model, the bottom pile sludge removal reverse circulation device includes a slag discharge pipe 100 and an air duct 200. The water suction end 101 of the slag discharge pipe 100 extends below the liquid level, and the slag discharge end 102 extends to the sedimentation tank; the air outlet end 201 of the air duct 200 is connected to the side wall of the water suction end 101 of the slag discharge pipe 100 and is in communication with the slag discharge pipe 100. The air inlet end 202 is connected to an air compressor. Among them, the air outlet direction of the air outlet end 201 is inclined upward towards the slag discharge pipe 100. Specifically, in this embodiment, during the air outlet process of the air duct 200, air bubbles will be formed in the mud. The generation of air bubbles will wrap the rock debris and sediment, mix them together, and enter the slag discharge pipe 100 along with the mud, improving the cleaning efficiency.

[0033] In order to further improve the efficiency, both the water suction end 101 and the air outlet end 201 are arranged below the liquid level, so as to generate enough air bubbles in the mud and wrap more rock debris and sediment to improve the removal efficiency.

[0034] As Embodiment 2 of the present utility model, the bottom pile sludge removal reverse circulation device includes a slag discharge pipe 100 and an air duct 200. The water suction end 101 of the slag discharge pipe 100 extends below the liquid level, and the slag discharge end 102 is between 0 and 3 cm on the liquid surface; the air outlet end 201 of the air duct 200 is connected to the side wall of the water suction end 101 of the slag discharge pipe 100 and is in communication with the slag discharge pipe 100. The air inlet end 202 is connected to an air compressor. Among them, the air outlet direction of the air outlet end 201 is inclined upward towards the slag discharge pipe 100. In this embodiment, during the air outlet process of the air duct 200, air bubbles will be formed in the mud. The generation of air bubbles will wrap the rock debris and sediment, mix them together, and enter the slag discharge pipe 100 along with the mud, improving the cleaning efficiency. Compared with Embodiment 1, in Embodiment 2, by being away from the liquid level, mud backflow can be avoided to a certain extent, promoting the reverse circulation of sludge removal.

[0035] For further optimization of the above Embodiment 1 and Embodiment 2, refer to Figure 2, the bottom sludge cleaning and reverse circulation device of the embodiment of the present utility model further includes a sleeve 300. The sleeve 300 is inserted into the pile pit, the end of the sleeve 300 abuts against the bottom of the pile pit, the upper end of the sleeve 300 protrudes from the pile pit, and both the slag discharge pipe 100 and the air pipe 200 are built inside the sleeve 300. In actual sludge cleaning work, the shape of the sleeve 300 should match the pile pit. During the process of inserting into the pile pit, the cuttings on the pit wall can be pushed to the bottom of the pile pit, and then in cooperation with the slag discharge pipe 100 and the air pipe 200, the cuttings and sediment in the pile pit can be fully discharged.

[0036] Furthermore, in order to better process the cuttings around the pile pit, referring to Figure 1 and Figure 4 , an inclined surface 310 inclined inward is provided at the end of the sleeve 300. As the casing moves downward, the cuttings can enter the inside of the casing under the guidance of the inclined surface 310 and sink in the mud.

[0037] In some embodiments, referring to Figure 4 , the air outlet direction of the air outlet end 201 is tangent to the slag discharge pipe 100 (such as the air outlet direction in the A direction in Figure 4 ). The wind direction tangent to the slag discharge pipe 100 can form a vortex inside the slag discharge pipe 100, increasing the pressure difference and sucking the mud into the slag discharge pipe 100. Preferably, in order to guide the air flow and make the air flow better form a vortex, referring to Figure 5 , a guide groove 110 is provided on the inner side surface of the slag discharge pipe 100, and the guide groove 110 is arranged in a spiral shape. When the air flow contacts the guide groove 110, most of the air flow will flow along the guide groove 110 and form a spiral vortex to adsorb the mud.

[0038] Preferably, referring to Figure 4 , the air outlet end 201 is welded and fixed to the side wall of the slag discharge pipe 100. To prevent the air outlet end 201 from falling off the slag discharge pipe 100 and ensure the normal progress of the sludge cleaning work.

[0039] In some embodiments, referring to Figures 1 to 3 , the air pipe 200 includes a hose 210 and a nozzle 220. The air outlet end 201 is arranged on the nozzle 220, the nozzle 220 is fixedly connected to the hose 210, and the air inlet end 202 is arranged on the hose 210. Combining the above description, the nozzle 220 is directly fixed to the outer wall of the slag discharge pipe 100, and the setting of the hose 210 can facilitate the placement of the air pipe 200.

[0040] It should be mentioned that, referring to Figure 3, the bottom sludge cleaning reverse circulation device further includes a water delivery pipe 400. The water outlet end 410 of the water delivery pipe 400 is located below the liquid level, and the water inlet end 420 is connected to a water delivery device 430. During the sludge cleaning process, water can be continuously supplemented to make the mud full, which is convenient for the slag discharge pipe 100 to adsorb the mud with cuttings and sediment. Specifically, the water outlet end 410 extends to the bottom of the pile pit.

[0041] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the relevant art, various changes can be made without departing from the gist of the present invention.
