[0043] The following will further describe the present utility model with specific embodiments in conjunction with the attached Figures 1-10 drawings.

[0044] A sludge suction traveling crane with a frame structure involved in this technical solution is a device adapted to a sedimentation tank. The sedimentation tank 100 is one of the key devices for water purification environment. Water enters from one end in the length direction of the sedimentation tank and flows out from the other end in the length direction. Suspended substances and particulate matters in the water gather and deposit at the bottom of the tank. A sludge discharge channel 200 is arranged outside the sedimentation tank 100, and the sludge discharge channel 200 is lower than the bottom of the sedimentation tank. Guide rails 300 are installed on the tops of both side walls of the sedimentation tank 100, and the sludge suction traveling crane 400 is installed on the guide rails. This technical solution is applicable to a sedimentation tank with a water collecting tank 500 horizontally arranged in the middle.

[0045] Specifically, the sludge suction traveling crane 400 with a frame structure in this technical solution includes a traveling crane body, two traveling driving devices 5 and a siphon sludge suction device 6;

[0046] The traveling crane body includes a traveling crane beam 1, a left suspension bracket 2, a right suspension bracket 3 and a bottom cross beam 4;

[0047] The lower part on the left side of the traveling crane beam 1 is provided with a left suspension bracket 2, and the lower part on the right side is provided with a right suspension bracket 3. The lower ends of the left suspension bracket 2 and the right suspension bracket 3 are respectively connected to both ends of the bottom cross beam 4. Chambers 21 for the sludge suction pipe to extend through are arranged inside the left suspension bracket 2 and the right suspension bracket 3. A plurality of sludge suction stations 41 for placing the sludge suction pipe are arranged on the bottom cross beam 4. Both the left suspension bracket 2 and the right suspension bracket 3 include four vertically arranged square rods 22 and several groups of support rods 23 cross - arranged between adjacent square rods. The four square rods enclose a cubic column with a larger upper part and a smaller lower part.

[0048] The first traveling driving device 5 is installed on the lower side of the traveling crane beam under the outer side of the left suspension bracket 2, and the second traveling driving device 5 is installed on the lower side of the traveling crane beam under the outer side of the right suspension bracket.

[0049] The siphon sludge suction device 6 includes a plurality of sludge suction pipes 61, a self - priming pump 62, a siphon pipe 63 and a solenoid valve 64;

[0050] The sludge suction pipe 61 is fixedly installed on the traveling beam 1. One end of the sludge suction pipe 61 extends downward along the left hanger or the right hanger to the bottom cross beam 4, and then extends along the bottom cross beam to the corresponding sludge suction station 41.

[0051] The self-priming pump 62 is installed on the traveling beam 1; the suction pipe 621 of the self-priming pump extends into the sedimentation tank, and the discharge pipe 622 of the self-priming pump extends to the outside of the sedimentation tank; the discharge pipe 622 of the self-priming pump is connected to the sludge suction pipe 61 through a siphon pipe 63; during the process of the self-priming pump delivering water flow to the discharge pipe 622, the air in the sludge suction pipe 61 is introduced into the discharge pipe 622.

[0052] The electromagnetic valve 64 is arranged on one side of the siphon pipe 63, and the electromagnetic valve 64 controls the siphon pipe 63 to be communicated with or closed to the atmospheric pressure in the external environment.

[0053] A plurality of diamond-shaped scrapers 42 are arranged on the lower side of the bottom cross beam. The front and rear sides of the diamond-shaped scraper are provided with pointed parts 421; the sludge suction stations are formed between two adjacent diamond-shaped scrapers; the sludge suction nozzle 611 at the lower end of the sludge suction pipe is located in the sludge suction station 41, and the shape of the sludge suction nozzle 611 is a flat triangle. The diamond-shaped scraper is a complete closed structure on the plane, with high structural strength and not easy to deform; the front and rear sides of the diamond-shaped scraper 42 are welded to the bottom cross beam, further strengthening the anti-deformation ability of the bottom cross beam 4; moreover, the diamond-shaped scraper can gather the sludge to both sides without being affected during the forward and backward movement of the sludge suction traveling crane. Therefore, after a single sludge suction is completed, it does not need to return to the original position, and it can directly work when sludge suction is required next time.

[0054] Preferably, the output end of the sludge suction pipe 61 extends into the water seal box 7.

[0055] The water seal box 7 is lower than the bottom of the sedimentation tank; the water seal box 7 includes an inner box body 72 and an outer box body 71. The opening of the inner box body 72 faces upward, and the opening of the outer box body 71 faces downward; the outer box body is buckled above the inner box body, and an overflow groove 73 is formed between the inner box body and the outer box body; the output end of the sludge suction pipe is inserted from the top surface of the outer box body and extends into the inner box body. The water flow and sludge will first enter the inner box body, and then overflow to the outside after the inner box body is full; part of the noise and vibration generated at the outlet of the sludge suction pipe will be absorbed in the inner box body and the outer box body, and the water seal box can effectively reduce the overall noise and vibration; for the formation of the siphon, the outlet of the sludge suction pipe must be water-sealed, and the water seal box can also ensure the sealing performance of the outlet of the sludge suction pipe to ensure the formation of the siphon phenomenon.

[0056] Preferably, the inner box body 72 is in a "∪" shape, and the outer box body 71 is in a "∩" shape; the width and height of the outer box body are both larger than those of the inner box body.

[0057] Preferably, the siphon 63 includes a main siphon pipe 631, a first-stage siphon branch pipe 632, and a second-stage siphon branch pipe 633; the number of the first-stage siphon branch pipes 632 is the same as that of the sludge suction pipes 61, and each first-stage siphon branch pipe is respectively communicated with the corresponding sludge suction pipe, and all the first-stage siphon branch pipes are communicated to the main siphon pipe;

[0058] The main siphon pipe is communicated with the second-stage siphon branch pipe, and the other end of the second-stage siphon branch pipe is communicated with the water outlet pipe 622 of the self-priming pump;

[0059] The second-stage siphon branch pipe 633 is arranged obliquely from top to bottom, and the included angle between the second-stage siphon branch pipe and the water outlet pipe of the self-priming pump is an acute angle less than or equal to 45 degrees. When the high-speed water flow passes through the water outlet pipe 622, the air in the second-stage siphon branch pipe 633 is carried away. One end of the sludge suction pipe 61 is immersed in the sedimentation tank, and the other end of the sludge suction pipe is immersed in the sludge discharge channel or the water seal box. The air pressure in the sludge suction pipe gradually becomes lower; under the action of the atmospheric pressure, the sludge and water in the sedimentation tank will be pressed into the sludge suction pipe. After reaching a certain degree, the self-priming pump can be stopped and the sludge can be sucked by relying on the siphon effect; when the sludge suction step is completed, the solenoid valve is opened to allow air to enter the siphon to break the siphon phenomenon, thereby stopping the sludge discharge. In this embodiment, the sludge suction pipes 61 are distributed on both sides of the water outlet pipe 622 and are symmetrically arranged, further improving the stability of the overall structure. A pressure gauge 65 is provided on the siphon. In the prior art, there is a scheme of aggregating the sludge suction pipes into a larger main sludge suction pipe and then communicating with the siphon through the main sludge suction pipe. The siphon effect in the initial stage of this scheme is poor, and more water resources will be wasted.

[0060] Preferably, flat surfaces 422 are provided on the transverse sides of the diamond-shaped scraper. The sludge suction nozzle 611 is installed on the sludge suction pipe 61. The sludge suction nozzle 611 shakes back and forth during use, and the flat surfaces 422 enable the sludge suction nozzle 611 to maintain a good sludge suction effect.

[0061] Preferably, half diamond-shaped scrapers 43 are provided at both ends of the bottom cross beam, and the half diamond-shaped scrapers guide the sludge towards the middle. The sludge scraping effect at the two side edges of the sedimentation tank is not very good, and the effect of guiding the sludge towards the middle is better.

[0062] In this technical solution, there are a total of 16 sludge suction pipes, with 8 on each side. As Figure 8 and 9 shown, 8 sludge suction pipes extend along the right hanger to the bottom cross beam; the 8 sludge suction pipes are then divided into two groups. Among the two groups of sludge suction pipes, the inner sludge suction pipes enter the sludge suction station alternately, making the overall layout more reasonable, more stable, and easier to maintain.

[0063] Preferably, a plurality of receiving pipes 74 are provided at the top of the outer box body; the number of the receiving pipes is the same as that of the sludge suction pipes; the lower ends of the receiving pipes extend into the inner box body, and the upper ends of the receiving pipes are connected to the corresponding sludge suction pipes 61 through flange plates 75; since the sludge suction pipes are directly connected to the water seal box and the number of the sludge suction pipes is relatively large, the flange plates between two adjacent receiving pipes are staggered in the vertical height, so that the sludge suction pipes can be closer together more compactly. The design of the receiving pipes can facilitate the connection between the water seal box and the sludge suction pipes and the overall assembly.

[0064] The foregoing has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments, and what is described in the above embodiments and the specification is only to illustrate the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will also have various changes and improvements, and these changes and improvements fall within the scope of the present invention claimed.
