DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1 to 3In the embodiment of the utility model, the foam filtering device of the concrete foaming machine includes a conveying pipe 1, an oblique pipe 8 protruding downward is integrally formed at the lower part of the outer periphery of the conveying pipe 1, the inner cavity of the oblique pipe 8 is connected to the inner cavity of the conveying pipe 1, and a filtering mechanism extending to the inner cavity of the conveying pipe 1 is installed below the oblique pipe 8, and the filtering mechanism is used to intercept and filter impurities contained in the foam, and the top and bottom of the oblique pipe 8 are both open structures, and a connector 12 is threadedly connected to the bottom end of the inner wall of the oblique pipe 8, and a rotating handle 9 is integrally formed at the bottom end of the connector 12, and a filter screen 13 with a porous structure is fixedly connected to the top of the connector 12, and the top of the filter screen 13 is located on the inner wall of the conveying pipe 1, and the top of the oblique pipe 8 is an inclined structure; a spiral mechanism extending to the inner wall of the filter screen 13 is rotatably installed below the filtering mechanism, and the spiral mechanism is used to squeeze the impurities filtered below the filter screen 13 downward to ensure the smooth flow channel of the filter screen 13.

[0020] In this embodiment: the foam foamed by the foaming agent is pumped into the pump body and delivered to the delivery pipe 1. When the foam passes through the delivery pipe 1, the foam passes through the filter 13, and the impurities carried by the foam are intercepted by the filter 13. Then, the spiral mechanism is rotated, and the impurities attached to the inner wall of the filter 13 are screwed down during the rotation process, so as to avoid the impurities blocking the flow channel of the filter 13, maintain the flow channel of the foam, and avoid the flow blockage of the foam.

[0021] As impurities gradually accumulate, the rotating handle 9 is turned, which drives the connecting head 12 to rotate. At this time, the connecting head 12 is completely separated from the inner wall of the inclined tube 8. At this time, the rotating handle 9 can be pulled, and the rotating handle 9 drives the filter screen 13 to move out from the inner wall of the inclined tube 8 through the connecting head 12, so that the impurities accumulated in the filter screen 13 can be discharged, and then the cleaned filter mechanism can be connected to the inner wall of the inclined tube 8 again.

[0022] Please refer to Figure 1 , Figure 2 and Figure 3 The spiral mechanism includes a rotating shaft 10 rotatably mounted with a rotating handle 9. The rotating shaft 10 extends from the bottom of the rotating handle 9 to the inner cavity of the filter 13. A rotating handle 11 is fixedly mounted on the bottom end of the rotating shaft 10. The outer periphery of the rotating shaft 10 is located in the inner cavity of the filter 13 and is fixedly connected with a spiral plate 14.

[0023] In this embodiment: During the foam transportation process, by rotating the handle 11, the handle 11 drives the rotating shaft 10 to rotate, and the rotating shaft 10 can drive the spiral plate 14 to rotate. Since the outermost side of the spiral plate 14 contacts the inner wall of the filter net 13, the rotating spiral plate 14 can scrape off the impurities attached to the inner wall of the filter net 13, causing the intercepted and filtered impurities to accumulate downward, preventing the flow passage of the filter net 13 from being affected and maintaining the normal flow of the foam.

[0024] Please refer specifically to Figure 1 , an installation plate 2 is connected to the outer periphery of the conveying pipe 1 through a fixing member, and a connecting handle 3 is fixedly installed on the top of the installation plate 2.

[0025] In this embodiment: By holding the connecting handle 3 by hand, the connecting handle 3 drives the conveying pipe 1 to move, and the foam in the conveying pipe 1 can be conveyed into the mixer filled with concrete.

[0026] Please refer specifically to Figure 1 , the output end of the conveying pipe 1 is detachably connected to a nozzle 7 through a thread, and a second hexagonal head 6 with a hexagonal structure is integrally formed at one end of the outer periphery of the nozzle 7.

[0027] In this embodiment: By docking a wrench with the second hexagonal head 6, the nozzle 7 can be installed or disassembled.

[0028] Please refer specifically to Figure 1 , the input end of the conveying pipe 1 is threadedly connected to a hose 5, and a first hexagonal head 4 with a hexagonal structure is integrally formed at one end of the outer periphery of the hose 5.

[0029] In this embodiment: By docking a wrench with the first hexagonal head 4, the hose 5 can be installed or disassembled.

[0030] Please refer specifically to Figure 1 , a sealing ring is installed at the connection of the hose 5, the nozzle 7 and the conveying pipe 1.

[0031] In this embodiment: The sealing ring is used to improve the sealing performance of the connection position and prevent foam from leaking at the connection of the hose 5, the nozzle 7 and the conveying pipe 1.

[0032] The above-mentioned is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent replacements or changes, and should be covered within the protection scope of the present invention.
