Obviously, the embodiments described below are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0026] The following will further illustrate the technical solutions of the present invention in conjunction with the drawings and through specific implementation manners.

[0027] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention 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 therefore should not be construed as a limitation on the present invention.

[0028] Please refer to Figures 1-5 As shown, a sediment cleaning device for a sewage treatment aeration tank includes a spray elbow 1, a sewage suction elbow 2, a strip brush plate 3, a disinfection nozzle 4, an internal conduit 410, a strip box 5, a liquid inlet pipe 6, a sewage discharge pipe 7, a second pump body 8, an L-shaped plate 10, a double piston rod cylinder 11, an oil cylinder 12 and a U-shaped carrier 16. The spray elbow 1 and the sewage suction elbow 2 are horizontally and reversely distributed. One end of a row of spray elbows 1 is communicated with the upper chamber 520 inside the strip box 5, and one end of a row of sewage suction elbows 2 is communicated with the lower chamber 530 inside the strip box 5. The liquid inlet pipe 6 communicated with the upper chamber 520 is connected to the output port of one of the second pump bodies 8, and the sewage discharge pipe 7 communicated with the lower chamber 530 is connected to the input port of the other second pump body 8.

[0029] Combined with Figure 1 、 Figure 2 、 Figure 4 and Figure 5 As shown, when the double piston rod cylinder 11 operates to drive the spray elbow 1 and the sewage suction elbow 2 connected by the strip box 5 to move synchronously and reciprocally, a row of spray elbows 1 at the upper end spray high-pressure flushing liquid through the corresponding second pump body 8 during the reciprocating movement, and at the same time, the other second pump body 8 operates synchronously to suck and discharge the sludge slurry washed down at the corresponding port of the sewage suction elbow 2. At the same time, by using the horizontally and reversely distributed positional relationship between the spray elbow 1 and the sewage suction elbow 2, the function of flushing the deposited sludge and quickly sucking and discharging the sludge slurry is realized, and the diffusion and flowing area of the sludge slurry is reduced, avoiding the overflow of the flushing sludge slurry and greatly reducing the difficulty of subsequent cleaning of the inside of the tank body.

[0030] A disinfection nozzle 4 is installed inside the other port of each spray elbow 1 and at the other end port of each sewage suction elbow 2, and each disinfection nozzle 4 is connected and installed with an internal conduit 410. One end of the internal conduit 410 is connected and installed at the corresponding part of the external conduit 411, and the port in the middle of the external conduit 411 is connected to the output port of the first pump body 413 on the U-shaped carrier 16 through a pipe body. The input port of the first pump body 413 is connected to the inside of the external disinfectant container through a pipe body.

[0031] Refer toFigure 2 and Figure 4 As shown in Figure 4 , when high-pressure liquid is ejected from the injection elbow 1 and sludge slurry is sucked and discharged from the sewage suction elbow 2, the input port of the first pump body 413 is connected to the inside of the external disinfectant container through a pipe body, so that the disinfectant is sprayed out from the connected disinfection nozzle 4 through the external conduit 411 and the internal conduit 410, achieving the effect of killing the worms and bacteria growing in the sediment. Moreover, the disinfectant is sprayed out from the injection elbow 1 once and then sprayed head-on on the sludge slurry from the inside of the sewage suction elbow 2 twice, enhancing the sufficiency of disinfecting and sterilizing the sludge.

[0032] The rear edge of the strip brush plate 3 is fixedly connected to the edge of one side of the bottom of the strip box 5. A double-rod piston cylinder 11 is connected and installed between the two triangular plates 510 at the top of the strip box 5. Two oil cylinders 12 are symmetrically installed at the top of the L-shaped plate 10 connected to the cylinder body part of the double-rod piston cylinder 11, and the cylinder body parts of the two oil cylinders 12 are fixedly connected to one end face of the same U-shaped carrier 16.

[0033] Referring to Figure 1 and Figure 2 As shown in Figure 2 , when the double-rod piston cylinder 11 is operated to drive the connected strip box 5 and its connected parts to move left and right reciprocally, the strip brush plate 3 installed on one side of the bottom of the strip box 5 is combined with the telescopic movement of the oil cylinder 12 to adjust the height position of the connected strip box 5, which can ensure the effectiveness of the brush needle surface of the strip brush plate 3 in contacting and rubbing the bottom of the pool body. At the same time, using the brush needle surface of the strip brush plate 3 can further prevent the diffusion of the sludge slurry.

[0034] As Figure 2 shown in Figure 2 , a guide rail 9 is installed on the back of the strip box 5, and the guide rail 9 is slidably connected to the corresponding part of one end of the L-shaped plate 10. Through the sliding connection between the guide rail 9 and one end of the L-shaped plate 10, the stability of the reciprocating movement of the strip box 5 and its connected parts is enhanced.

[0035] As Figure 1 shown in Figure 1 , the external conduit 411 is U-shaped, and the two pipe body parts on both sides of the external conduit 411 respectively correspond to the upper chamber 520 and the lower chamber 530. Electric control valves 412 are installed on the pipe body parts on both sides of the external conduit 411. By using the opening and closing of the electric control valves 412, the effect of controlling the flow direction of the incoming disinfectant is achieved, so as to meet the disinfection requirements.

[0036] Furthermore, two sliding seats 15 are symmetrically installed on the top of the U-shaped carrier 16, and the two sliding seats 15 are connected to the corresponding structural parts of the same external servo linear movement module. By setting the sliding seats 15, it is convenient to connect with the external servo linear movement module placed on the pool body, playing the role of changing the cleaning position.

[0037] Further, one end inside the U-shaped carrier 16 is fixedly connected to two symmetrically distributed second pump bodies 8, and both the second pump body 8 and the first pump body 413 are electrically connected to a pump body controller 13 located on the U-shaped carrier 16 through wires.

[0038] Further, both the liquid inlet pipe 6 and the sewage discharge pipe 7 are flexible material pipe bodies.

[0039] Further, the double-rod piston cylinder 11 is connected to a pneumatic controller 14 located on the U-shaped carrier 16 through an air duct.

[0040] Working principle: As shown in Figure 1 , Figure 2 , Figure 4 and Figure 5 , when the double-rod piston cylinder 11 operates to drive the injection elbow pipe 1 and the sewage suction elbow pipe 2 connected by the strip-shaped box 5 to be in a synchronous reciprocating movement state, a row of injection elbow pipes 1 at the upper end eject high-pressure flushing liquid through the corresponding second pump bodies 8 during the reciprocating movement, and the corresponding other second pump body 8 operates synchronously to suck and discharge the sludge slurry washed down at the corresponding port of the sewage suction elbow pipe 2. At the same time, by using the horizontal reverse distribution positional relationship between the injection elbow pipe 1 and the sewage suction elbow pipe 2, the function of flushing the deposited silt while quickly sucking and discharging the sludge slurry is realized, and the diffusion and flowing area of the sludge slurry is reduced, avoiding the overflow of the flushing sludge slurry, and greatly reducing the difficulty of subsequent cleaning inside the pool body;

[0041] Referring to Figure 2 and Figure 4 , when the injection elbow pipe 1 ejects high-pressure liquid and the sewage suction elbow pipe 2 sucks and discharges the sludge slurry, the input port of the first pump body 413 is connected to the inside of an external disinfectant container through a pipe body, so that the disinfectant passes through the external conduit 411 and the internal conduit 410 and is sprayed out from the connected disinfection nozzle 4 until it reaches the effect of killing the insects and bacteria growing in the sediment. Moreover, the disinfectant is sprayed out from the injection elbow pipe 1 once and then sprayed against the sludge slurry from the inside of the sewage suction elbow pipe 2 a second time, enhancing the sufficiency of disinfecting and sterilizing the sludge;

[0042] Referring to Figure 1 and Figure 2 , when the double-rod piston cylinder 11 operates to drive the connected strip-shaped box 5 and its connected parts to move left and right reciprocally, the strip-shaped brush plate 3 installed on one side of the bottom of the strip-shaped box 5 is used, and in combination with the telescopic movement of the oil cylinder 12 to adjust the height position of the connected strip-shaped box 5, the effectiveness of the brush needle surface of the strip-shaped brush plate 3 contacting and rubbing the bottom of the pool body can be ensured. At the same time, by using the brush needle surface of the strip-shaped brush plate 3, the diffusion of the sludge slurry can be further blocked;

[0043] In summary: Compared with the prior art, the differences are as follows:

[0044] 1. A row of spray bent pipes located at the upper end eject high-pressure flushing liquid through the corresponding second pump body during the reciprocating movement, and combine with the synchronous operation of another corresponding second pump body to suck and discharge the sludge slurry washed down at the corresponding port of the sewage suction bent pipe. At the same time, by using the horizontal reverse distribution relationship between the spray bent pipe and the sewage suction bent pipe, the function of flushing the deposited sludge while quickly sucking and discharging the sludge slurry is realized, with high flushing and cleaning efficiency, reduced diffusion and flowing area of the sludge slurry, avoiding the overflow of the flushing sludge slurry, and greatly reducing the difficulty of subsequent cleaning inside the tank body;

[0045] 2. The disinfectant is sprayed out from the spray bent pipe once, and then sprayed against the sludge slurry twice from the inside of the sewage suction bent pipe, enhancing the sufficiency of disinfection and sterilization of the sludge;

[0046] 3. The height position of the connected strip box is adjusted by the telescopic movement of the oil cylinder, which can ensure the effectiveness of the contact and scrubbing between the brush needle surface of the strip brush plate and the bottom of the tank body. At the same time, by using the brush needle surface of the strip brush plate, the diffusion of the sludge slurry can be further blocked, and less liquid splashes.

[0047] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, in any aspect, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description.
