[0002] Solid-liquid separation of wastewater is the first line of defense in wastewater treatment. Wastewater sedimentation technology, as one of the core processes of solid-liquid separation, directly affects the subsequent treatment of wastewater due to its cleaning efficiency and related maintenance. In wastewater sedimentation technology, a large amount of sludge accumulates inside the sedimentation tank, which needs to be removed by relevant equipment. A gantry crane can effectively remove a large amount of internal sludge, but the gantry crane cannot effectively clean the sludge on both sides of the sedimentation tank, and the accumulation of sludge on both sides will also have a great impact on the gantry crane's cleaning.

[0003] In existing wastewater sedimentation processes, the continuous movement of gantry cranes is often used to clean the sludge in the sedimentation tank, which greatly improves efficiency compared to manual cleaning. However, the sludge on both sides of the sedimentation tank cannot be effectively cleaned. The accumulation of sludge on both sides will affect the formation of the gantry crane, thus reducing the efficiency of sludge cleaning. Summary of the Invention

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model. Furthermore, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0021] This novel embodiment provides a gantry crane device for scraping sludge from the bottom of a wastewater treatment pond, such as... Figure 1 , Figure 2As shown, the system includes a stair platform 1, a sludge pumping mechanism 2, a sludge scraping mechanism 3, and an auxiliary mechanism 4. The stair platform 1 is installed on a slide rail at the top of the wall 5 and can move back and forth along the slide rail over a certain distance. The sludge pumping mechanism 2 is installed at the top of the wall 5 and located behind the stair platform 1. The sludge pumping mechanism 2 has multiple sludge pumping pipes (four in this embodiment) and a sludge discharge pipe 25. The sludge pumping mechanism 2, through the cooperation of the sludge pumping pipes and the sludge discharge pipe 25, pumps the sludge from the bottom of the sewage treatment tank and discharges it to the sludge discharge channel 6. Multiple sludge scraping mechanisms 3 (four in this embodiment) are installed at the bottom of the stair platform 1 and are located within the wall passageway of the wall 5. When the gantry crane is activated to clean the accumulated sludge at the bottom of the sewage treatment tank, the sludge scraping mechanism 3 divides and breaks up the accumulated sludge at the bottom, so that the sludge pumping mechanism 2 can suck up the loose sludge. The auxiliary mechanism 4 is installed on the top of the wall 5 and located at the end of the wall passage. During the long-term use of the gantry crane, the sludge scraping mechanism 3 will accumulate sludge at the bottom of the wall passage at the end of the wall 5 due to the installation position and the gantry crane stroke. This part of the sludge that cannot be cleaned will slowly accumulate forward, thereby reducing the operable stroke of the gantry crane. The auxiliary mechanism 4 is used regularly to facilitate the cleaning of the accumulated sludge at the bottom of the wall passage at the end of the wall 5 to ensure the normal use of the gantry crane. The device of this utility model enables the observation of gantry crane operation and facilitates gantry crane maintenance through a stair platform installed at the top of the wall. A mud-dredging mechanism installed at the top of the wall and behind the stair platform removes the mud and sand accumulated at the bottom of the wall passage. Multiple mud-scraping mechanisms installed at the bottom of the stair platform divide and disperse the mud and sand accumulated at the bottom of the wall passage. An auxiliary mechanism installed at the top of the wall and at the end of the wall passage divides and disperses the mud and sand accumulated at the end of the wall passage.

[0022] Specifically, such as Figure 1 , Figure 2 As shown, the stair platform 1 includes a mobile platform 11, an inclined ladder 12, and a handrail 13. The mobile platform 11 is the main working platform for gantry crane maintenance and monitoring. Inclined ladders 12 are installed on both sides of the mobile platform 11. The bottom of the inclined ladders 12 has a gap with the wall 5 and does not contact each other. The handrail 13 is installed on both sides of the stair platform 1. A sliding device that can cooperate with the top slide rail of the wall 5 is installed at the bottom of the stair platform 1. The stair platform 1 is mainly used to provide a working platform for operators to monitor the operation of the gantry crane and to maintain the gantry crane device.

[0023] Specifically, such as Figure 1 , Figure 2As shown, the sludge pumping mechanism 2 includes a first sludge pumping pipe 21, a second sludge pumping pipe 22, a third sludge pumping pipe 23, a fourth sludge pumping pipe 24, a sludge discharge pipe 25, and a sludge pump 26. The first sludge pumping pipe 21, the second sludge pumping pipe 22, the third sludge pumping pipe 23, and the fourth sludge pumping pipe 24 are respectively installed on the mounting holes of the sludge pumping mounting base 35 of each sludge scraping mechanism 3 and at the corresponding positions of the sludge pump 26. The sludge pump 26 is installed on the top of the wall 5 and located behind the stair platform 1. The sludge discharge pipe 25 is installed on the other side of the sludge pump 26. One end of the sludge discharge pipe 25 is connected to the sludge pump 26, and the other end leads to the sludge discharge channel 6 to discharge the sludge into the sludge discharge channel 6. The sludge pumping mechanism 2 uses the operation of the sludge pump 26 to pump out the sludge accumulated at the bottom of the sewage treatment tank through the sludge pumping pipe and discharge the sludge into the sludge discharge channel 6 through the sludge discharge pipe 25.

[0024] Specifically, such as Figure 3 , Figure 4As shown, the sludge scraping mechanism 3 includes a sludge scraping mounting base 31, a sludge scraping support column 32, a flushing mounting base 33, a high-pressure water nozzle 34, a sludge extraction mounting base 35, a sludge scraping main plate 36, a sludge scraping column 37, and a sludge scraping blade 38. The sludge scraping mounting base 31 is installed on the front and rear of the top of the sludge scraping support column 32. Multiple sludge scraping mounting bases 31 connect the sludge scraping mechanism 3 to the stair platform 1 (two in this embodiment). Multiple flushing mounting bases 33 (two in this embodiment) are installed on both sides of the bottom of the sludge scraping support column 32. One end of the flushing mounting base 33 is connected to the bottom of the sludge scraping support column 32, and the other end has a mounting hole for the high-pressure water nozzle 34. The high-pressure water nozzle 34 is installed on the corresponding opening of the flushing mounting base 33. The high-pressure water nozzle 34 can spray high-pressure water to further disperse the mud and sand blocks cut and broken by the auxiliary mechanism 4, so that the sludge scraping mechanism 3 can collect the bottom accumulation at the end of the wall passageway. The mud and sand are extracted. One end of the mud extraction mounting base 35 is connected to the bottom of the mud scraping support column 32, and the other end has an installation hole for the mud extraction pipe. Multiple mud scraping main plates 36 (two in this embodiment) are installed on the bottom front and rear of the mud scraping support column 32. Multiple mud scraping columns 37 are installed on the mud scraping main plates 36. The mud scraping columns 37 are connected to the mud scraping main plates 36 by bolts. A mud scraping main blade 38 is installed at the bottom of each mud scraping column 37. The top mounting surface of the mud scraping main blade 38 has a stepped surface for installation and positioning. Multiple installation holes for installing the mud scraping columns 37 are opened on the mud scraping main plates 36. The mud scraping columns 37 are installed in an intermittent manner on the same mud scraping main plate 36, and in a staggered manner on different mud scraping main plates 36, to ensure that the area of ​​mud and sand cut by the mud scraping main blade 38 meets the requirements and that the blade head of the mud scraping main blade 38 faces the same direction. The device of this utility model, through multiple sludge scraping mechanisms installed at the bottom of the stair platform, achieves the function of dividing and breaking up the mud and sand accumulated at the bottom of the wall passage. The high-pressure water nozzles installed on it can enhance the effect of dividing and breaking up the mud and sand, making it easier for the sludge scraping mechanism to pick up the mud and sand. Through the staggered installation of multiple sludge scraping blades, a larger area of ​​mud and sand can be divided and broken up, enhancing the working effect of the gantry crane device in clearing mud and sand.

[0025] Specifically, such as Figure 5 , Figure 6As shown, the auxiliary mechanism 4 includes a mounting cover plate 41, telescopic rods 42, a drive mounting plate 43, an auxiliary blade turntable 44, a scraping auxiliary blade 45, and a drive device 46. The mounting cover plate 41 is used to connect the auxiliary mechanism 4 to the top of the end of the wall passage of the wall 5 by bolting. A window is opened on the mounting cover plate 41 to monitor the working status of the auxiliary mechanism 4. Multiple telescopic rods 42 are installed at the corresponding mounting holes at the bottom of the mounting cover plate 41 (four in this embodiment). The telescopic rods 42 need to be adjusted in length and fixed according to the actual working needs before installation. In the device, one end of the telescopic rod 42 is installed on the mounting cover plate 41, and the other end is installed on the top of the drive mounting plate 43. A drive device 46 is installed on the drive mounting plate 43. The drive device 46 needs to be protected with a waterproof and corrosion-resistant shell. An auxiliary blade turntable 44 is installed on the drive device 46. The auxiliary blade turntable 44 can rotate under the drive of the drive device 46. Multiple mounting holes for scraping auxiliary blades 45 are opened on the auxiliary blade turntable 44. The number of scraping auxiliary blades 45 needs to be adjusted according to actual use. It is necessary to ensure that the scraping auxiliary blades 45 are installed on the auxiliary blade turntable 44 in a staggered manner. The device of this utility model, through an auxiliary mechanism installed at the top of the wall and located at the end of the wall passage, achieves the function of dividing and breaking up the mud and sand accumulated at the bottom of the wall passage. By adjusting the actual length of each telescopic rod, the effect of dividing and breaking up the mud and sand at the bottom of the wall passage can be controlled. Through the auxiliary blade turntable and the mud scraping auxiliary blade installed on the auxiliary blade turntable, the mud and sand at the bottom of the wall passage can be divided and broken up. The installation method of the mud scraping auxiliary blade on the auxiliary blade turntable can be adjusted according to the actual effect.

[0026] Although the high-pressure water nozzle 34 of this disclosure is often used when the auxiliary mechanism 4 is working to enhance the working effect of the mud scraping auxiliary blade 45 in the auxiliary mechanism 4 in dividing and breaking up mud and sand, and the mud and sand blocks are dispersed by high-pressure water flow, the high-pressure water nozzle 34 can also be used, depending on the actual situation, to enhance the working effect of the mud scraping main blade 38 in the mud scraping mechanism 3 in dividing and breaking up mud and sand during the operation of the gantry crane device.

[0027] In another embodiment of this utility model, a gantry crane device for scraping sludge from the bottom of a sewage treatment pond is provided, comprising the following steps: Before the gantry crane is in operation, check whether the main scraper blade 38 on the gantry crane is deformed, cracked or rusted, and ensure that the main scraper blade 38 and the auxiliary scraper blade 45 fit the bottom of the pool in accordance with the design requirements.

[0028] Confirm that the preset sedimentation time in the sewage treatment tank has been completed, the thickness of the silt at the bottom of the tank has reached the threshold for starting the sludge scraping, and clear any obstacles on both sides of the gantry crane's running track and in the area around the tank.

[0029] The gantry crane is started, and the gantry crane moves to the other end of the pool at a set speed. The sludge scraper 38 fits against the bottom of the pool and breaks the hardened mud and sand into pieces, which are then pumped away from the bottom of the pool by the sludge suction pipe.

[0030] After the gantry crane completes its work, it returns to its original position and simultaneously starts the auxiliary mechanism 4 to remove the mud and sand inside the passageway of the sewage treatment tank wall. While the auxiliary mechanism 4 is running, the high-pressure water nozzle 34 of the sludge scraping mechanism 3 continuously sprays high-pressure water to flush the mud and sand, and the sludge pumping mechanism 2 continues to run to remove the mud and sand in this area.

[0031] After auxiliary mechanism 4 finishes operation, the gantry crane device is reset to ensure that the gantry crane device can return to its original design position.

[0032] Regularly maintain the gantry crane device, replace the main scraper blade 38 and auxiliary scraper blade 45, and check whether the gantry crane device parts are corroded, as well as whether there are any problems with the circuits and pipes.

[0033] In summary, the gantry crane device used for scraping sludge from the bottom of the sewage treatment pond can remove sludge from the bottom of the sewage treatment pond. In addition, it can also remove sludge deposited at the end of the wall passageway, preventing the gantry crane from being unable to return to its original position due to the influence of sludge inside.

[0034] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
