Description

Technical Field

[0001] This utility model mainly relates to the field of sludge treatment technology, specifically to an underwater sedimentation sludge suction device. Background Technology

[0002] In fields such as wastewater treatment, river dredging, and the maintenance of various aquatic environments, the treatment of underwater sediment sludge is a crucial task. With the rapid development of industry and the acceleration of urbanization, the types and quantities of pollutants in water bodies are constantly increasing, leading to increasingly complex compositions of underwater sediment sludge, which not only contains large amounts of organic matter and heavy metals, but may also be mixed with various solid wastes and impurities.

[0003] Traditional underwater sedimentation sludge treatment methods have many drawbacks. Early methods, such as manual dredging, were not only extremely inefficient but also labor-intensive, exposing workers to harsh working conditions and potential health risks. Later, some simple suction equipment emerged, which improved efficiency to some extent, but they often lacked effective mobility and were difficult to operate flexibly in large bodies of water, limiting their suction to specific small areas.

[0004] Some suction equipment lacks depth adjustment functionality, making it impossible to operate precisely according to the actual depth of sludge settling, resulting in poor suction performance and excessive sludge residue. More importantly, when dealing with sludge of complex composition, ordinary suction equipment lacks anti-clogging design. During the suction process, lumps, fibers, and other debris in the sludge easily clog pipes and pumps, causing frequent interruptions in suction operations, severely impacting work efficiency, and increasing maintenance and time costs.

[0033] It should be noted that the structures not described in this utility model are the same as or can be implemented using existing technology, and will not be elaborated here, as they do not involve the design points and improvement directions of this utility model. Example

[0034] See attached document Figures 1-8 An underwater sedimentation sludge suction device includes a frame 1, on which two drive wheel assemblies 2 are mounted, and at the bottom of the frame 1 are several driven wheels 3. A suction assembly 4 and a sludge pump 5 are mounted on the frame 1 and connected to each other. The suction assembly 4 is positioned between the two drive wheel assemblies 2. A lifting assembly 6 is also mounted on the frame 1 and positioned above the suction assembly 4. The output end of the lifting assembly 6 is connected to the lifting assembly 6.

[0035] The drive wheel assembly 2 includes a mounting box 21 fixed on the frame 1. Drive wheels 22 are rotatably mounted on both sides of the mounting box 21. Two sets of motors 23 and reducers 24 are connected inside the mounting box 21. The output end of the reducer 24 is connected to one drive wheel 22.

[0036] The suction assembly 4 includes a mounting bracket 41 fixed on the frame 1. An L-shaped suction pipe 42 is mounted on the mounting bracket 41. The lower end of the suction pipe 42 has a suction inlet 43, and the other end, a sludge outlet 47, is connected to the sludge pump 5. A vertically rotatable shaft 44 is mounted on the suction pipe 42. The upper end of the shaft 44 is connected to a motor 46 via a pulley assembly 45, and the lower end is connected to a cutting blade 48, which is located at the suction inlet 43. The cutting blade 48 is a propeller-type or serrated blade.

[0037] The lifting assembly 6 includes a support frame 61 fixed to the frame 1. A lifting cylinder 62 is mounted on the support frame 61. The piston rod of the lifting cylinder 62 is connected to a lifting plate 63. The lower end of the lifting plate 63 is connected to a mounting plate 64. A mounting bracket 41 is fixed to the lower end of the mounting plate 64. A guide shaft 65 is vertically mounted on the support frame 61. A guide block 66 is fixedly mounted on the lifting plate 63. The guide block 66 is slidably mounted on the guide shaft 65.

[0038] Working principle: Before starting the operation, the operator first checks whether the connections of each component of the equipment are secure and whether the electrical circuit is normal, to ensure that the equipment is in a safe and operable state.

[0039] The motor 23 in the drive wheel assembly 2 is started. After being powered on, the motor 23 begins to rotate, and the high-speed rotational power output is transmitted to the reducer 24. The function of the reducer 24 is to reduce the high speed of the motor 23 while increasing the output torque. After the speed reduction and torque amplification by the reducer 24, the output torque and speed reach the values ​​suitable for driving the drive wheel 22, thereby driving the drive wheel 22 to rotate.

[0040] The driven wheels 3 at the bottom of the frame 1 provide auxiliary support. When the drive wheel 22 rotates, the entire suction device moves along the underwater bottom or track under the drive of the drive wheel 22 and the cooperation of the driven wheels 3. The operator can precisely move the equipment to the underwater location where sludge needs to be suctioned by controlling the forward and reverse rotation and speed of the motor 23 according to the actual operation requirements. For example, in the aeration tank of a large sewage treatment plant, sludge may be distributed in different areas. In this way, the equipment can quickly and accurately reach the sludge accumulation area.

[0041] Once the equipment is moved to the designated position, the lifting cylinder 62 in the lifting assembly 6 is activated. At this time, the piston rod of the lifting cylinder 62 extends, providing power for the entire descent process. The piston rod pushes the lifting plate 63 downwards. The lifting plate 63 is tightly connected to the mounting plate 64 via a connector, so the descent of the lifting plate 63 causes the mounting plate 64 to move downwards synchronously. The mounting bracket 41 is fixed to the lower end of the mounting plate 64, so the mounting bracket 41 also descends, causing the suction port 43 at the lower end of the suction pipe 42 of the suction assembly 4 to gradually approach the underwater sedimented sludge. During this process, the guide shaft 65 and guide block 66 play crucial roles. The guide shaft 65 is vertically mounted on the support frame 61, and the guide block 66 is fixedly mounted on the lifting plate 63, with the guide block 66 tightly fitted to the guide shaft 65, allowing it to slide up and down. Their presence effectively limits the swaying and offset of the lifting plate 63 during descent, ensuring the stability and accuracy of the lifting process. Just as the guide rails and sliders ensure the smooth raising and lowering of the elevator car during operation, the guide shaft 65 and guide block 66 ensure that the suction assembly 4 can accurately descend to the target position.

[0042] When the suction inlet 43 approaches the sludge, motor 46 is started. Motor 46 is energized and operates, transmitting its rotational power to the shaft 44 via pulley assembly 45. Pulley assembly 45 consists of a driving pulley, a driven pulley, and a transmission belt. Power is transmitted using the friction between the belt and pulleys, and the rotational speed can be adjusted by changing the diameter ratio of the driving and driven pulleys. During this process, pulley assembly 45 adjusts the rotational speed of motor 46 to a suitable speed for the cutting tool 48, thereby driving the shaft 44 to rotate.

[0043] The lower end of the rotating shaft 44 is fixedly connected to the cutting tool 48, so the rotation of the rotating shaft 44 drives the cutting tool 48 to start rotating at high speed. At the same time, the sludge pump 5 is turned on, and the high-speed rotation of the impeller in the sludge pump 5 creates a negative pressure area in the pump body. Since the suction port 43 is in contact with the sludge, under the action of negative pressure, the settled sludge is sucked into the suction pipe 42.

[0044] As sludge is sucked in, rotating cutting blades 48 cut and break up lumps, fibers, and other debris in the sludge. If these debris are not treated, they can easily accumulate in the suction pipe 42 and sludge pump 5, causing blockages and affecting the normal operation of the suction process. After being cut by the cutting blades 48, the sludge becomes smaller particles or fragments, which smoothly pass through the suction pipe 42 and are transported from the sludge outlet 47 of the suction pipe 42 to the sludge pump 5, from where it is discharged to a designated location, such as a sludge treatment tank or transport vehicle.

[0045] After the suction operation is completed, the equipment needs to be removed from the work area and retrieved. First, the piston rod of the lifting cylinder 62 retracts, pulling the lifting plate 63 upward, which in turn drives the mounting plate 64, mounting bracket 41, and suction assembly 4 to rise and reset. Similarly, during the rising process, the guide shaft 65 and guide block 66 ensure the smoothness and accuracy of the rising process.

[0046] After the suction assembly 4 rises and resets, the power to the drive wheel assembly 2 is shut off, thus stopping the operation of motor 23. At this time, the drive wheel 22 stops rotating, and the equipment loses its driving force. Operators can manually or with the help of other auxiliary equipment slowly move the equipment away from the underwater working area to complete the equipment recovery work. For example, after river dredging operations are completed, the equipment can be moved to the shore for subsequent maintenance and upkeep.

[0047] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
