Description

Technical Field

[0001] This utility model relates to the field of sewage bottom cleaning technology, and in particular to a sewage bottom suction and cleaning device for sewage treatment plants. Background Technology

[0002] Disinfection contact tanks are indispensable final-stage structures in modern wastewater treatment processes. Their main function is to kill or inactivate residual pathogenic microorganisms, including bacteria, viruses, and parasite eggs, in the pre-treated wastewater, preventing them from entering natural water bodies or reuse systems with the effluent. This effectively blocks the transmission chain of waterborne diseases, ensuring public health and safety and maintaining environmental balance. It is hailed as the last "safety checkpoint" before wastewater discharge from the treatment plant. Even after passing through the secondary sedimentation tank, the effluent still contains very fine suspended solids and colloidal substances. In this "final retention tank," due to the extremely slow water flow, these substances gradually settle to the bottom under gravity. Over time, sludge deposits also accumulate at the bottom of the disinfection contact tank.

[0003] Currently, some wastewater treatment plants use manual sludge removal to clean the bottom of their disinfection contact tanks. However, this method is problematic due to the complex working environment and inherent safety risks. Disinfection contact tanks are semi-enclosed spaces with poor air circulation, potentially leading to the accumulation of toxic gases such as hydrogen sulfide and methane. Furthermore, the slippery bottom and confined space pose significant safety hazards to workers entering the tanks for sludge removal, including the risk of poisoning, suffocation, slips, falls, and mechanical collisions. This places extremely high demands on the professional skills and protective measures of the workers. Additionally, the sludge removal process requires suspending some processes or restricting water flow, potentially affecting the continuous operation of the wastewater treatment system. Moreover, manual cleaning has limitations in coverage, making it difficult to effectively remove large areas and continuous sediment from the tank bottom. Especially when the tank is not shut down, the ability to disturb and suction the deposited sludge is limited. Therefore, there is still room for improvement in the effectiveness of removing bottom contaminants in practical applications. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology in which some sewage treatment plants use manual sludge removal to clean the bottom of the pool. Due to the complex working environment, there are certain safety risks, and the cleaning range is limited to incomplete coverage. It is difficult to effectively remove large-scale and continuous sediments from the bottom of the pool. Especially under the condition of not stopping the pool, the disturbance and suction capacity of the deposited sludge is limited. Therefore, there is still room for improvement in the removal effect of pool bottom dirt in practical applications. This invention provides a pool bottom suction and cleaning device for sewage treatment plants.

[0005] The purpose of this utility model is achieved through the following technical solution: a sewage treatment plant bottom suction and cleaning device, including a disinfection contact tank and a mobile vehicle body located above the disinfection contact tank. The mobile vehicle body spans the disinfection contact tank and is equipped with an electric slide corresponding to the disinfection contact tank. The mobile vehicle body is provided with a through groove corresponding to the electric slide. A mobile platform is installed at the moving end of the electric slide. A lifting device is installed on the mobile platform. The lifting device can be an electric hoist. A sludge pump that is submerged in the bottom wall of the disinfection contact tank is installed at the lifting end of the lifting device. The bottom of the sludge pump's suction end is equipped with a suction hood, and the lower part of the suction hood has multiple suction windows arranged in a circumferential array. The moving end of the electric slide can drive the lifting equipment and sludge pump to move laterally along the disinfection contact pool, and the moving vehicle can drive the lifting equipment and sludge pump to move longitudinally along the disinfection contact pool.

[0006] By setting up a mobile vehicle and an electric slide to drive the lifting equipment and sludge pump to move longitudinally and laterally along the disinfection contact tank, the bottom of the disinfection contact tank can be thoroughly cleaned. This not only effectively saves manpower but also improves the cleaning efficiency and effect of the sludge at the bottom of the disinfection contact tank. Furthermore, the mobile vehicle can drive the lifting equipment and sludge pump to move along the disinfection contact tank, enabling effective cleaning of the sludge at the bottom of the disinfection contact tank without stopping the tank.

[0007] A further technical solution involves installing batteries on the mobile vehicle body that are connected to the electric slide, lifting equipment, and sludge pump respectively. The sludge pump is connected to the batteries via cables. By setting up the batteries to provide power to the electric slide, lifting equipment, and sludge pump, the power supply problem of the mobile vehicle body during movement is solved. At the same time, the mobile vehicle body can be an electric mobile trolley, with the batteries also electrically connected to the mobile vehicle body to meet the power supply needs of the mobile vehicle body.

[0008] A further technical solution involves installing a suction pipe extending beyond the disinfection contact tank at the sludge pump's discharge end. Two sets of clamping parts are installed on the mobile platform, located on either side of the lifting equipment. The suction pipe and cable pass through slots and engage with the two sets of clamping parts. Annular rubber sleeves are installed on the clamping parts, with the suction pipe and cable contacting the inner rings of the two sets of rubber sleeves. By having the suction pipe and cable pass through slots and engage with the two sets of clamping parts, the suction pipe and cable can be effectively secured. Furthermore, the fact that the suction pipe and cable are located on opposite sides of the lifting equipment effectively separates the chain, suction pipe, and cable at the lifting end of the lifting equipment during platform movement, preventing them from tangling and affecting the equipment's lifespan.

[0009] A further technical solution involves installing a mounting frame inside the suction hood. The mounting frame is located between the sludge pump's suction end and the suction window. Multiple sets of equally spaced blades are installed on the mounting frame, and the blades are rotatably connected to the mounting frame. By setting multiple sets of blades rotatably connected to the mounting frame, the blades rotate under the action of the water flow drawn in by the sludge pump, effectively breaking up clumps of sludge and preventing clumps of sludge from clogging the sludge pump's suction end, thereby improving the sludge cleaning effect.

[0010] A further technical solution is that the suction hood is tapered, narrower at the top and wider at the bottom, and the bottom of the suction hood is equipped with reinforcing ribs. The reinforcing ribs can enhance the strength of the bottom of the suction hood, thereby preventing damage when the bottom of the suction hood bumps against the bottom wall of the disinfection contact pool.

[0011] A further technical solution is to install a controller on the mobile vehicle body that is connected to the electric slide, lifting equipment, and sludge pump. The controller is connected to an external handheld terminal. By setting up the controller connected to the external handheld terminal, the starting and stopping operation of the electric slide, lifting equipment, and sludge pump can be controlled, allowing the staff to operate the equipment remotely and eliminating the safety risks caused by the complex working environment.

[0012] This utility model has the following advantages: By setting up a mobile vehicle and an electric slide to drive the lifting equipment and sludge pump to move longitudinally and laterally along the disinfection contact tank, the bottom of the disinfection contact tank can be thoroughly cleaned. This not only effectively saves manpower, reduces labor costs and safety risks, but also significantly improves the cleaning efficiency and effect of sludge at the bottom of the disinfection contact tank. Furthermore, the mobile vehicle can drive the lifting equipment and sludge pump to move along the disinfection contact tank, enabling effective cleaning of the sludge at the bottom of the disinfection contact tank without stopping the tank. By setting up multiple sets of blades that are rotatably connected to the mounting frame, the blades rotate under the action of the water flow sucked in by the sludge pump, effectively breaking up the clumps of sludge and preventing the clumps of sludge from clogging the suction end of the sludge pump.

[0019] like Figures 1-3 As shown, a wastewater treatment plant bottom suction and cleaning device includes a disinfection contact tank 1 and a mobile vehicle 2 located above the disinfection contact tank 1. The mobile vehicle 2 spans the disinfection contact tank 1 and is equipped with an electric slide 3 corresponding to the disinfection contact tank 1. The mobile vehicle 2 has a through groove 4 corresponding to the electric slide 3. The moving end of the electric slide 3 is equipped with a mobile platform 17. The mobile platform 17 is equipped with a lifting device 5, which can be an electric hoist. The lifting end of the lifting device 5 is equipped with a sludge pump 6 that is submerged in the bottom wall of the disinfection contact tank 1. The bottom of the sludge pump 6 is equipped with a sludge suction hood 7, and the lower part of the sludge suction hood 7 has multiple sets of sludge suction windows 13 arranged in a circular array. The moving end of the electric slide table 3 can drive the lifting equipment 5 and the sludge pump 6 to move laterally along the disinfection contact pool 1, and the moving vehicle 2 can drive the lifting equipment 5 and the sludge pump 6 to move longitudinally along the disinfection contact pool 1.

[0020] By setting up a mobile vehicle 2 and an electric slide 3 to drive the lifting equipment 5 and the sludge pump 6 to move longitudinally and laterally along the disinfection contact tank 1, the bottom of the disinfection contact tank 1 can be thoroughly cleaned by suction. This not only saves manpower but also improves the cleaning efficiency and effect of the sludge at the bottom of the disinfection contact tank 1. Furthermore, the mobile vehicle 2 can drive the lifting equipment 5 and the sludge pump 6 to move along the disinfection contact tank 1, which can effectively clean the sludge at the bottom of the disinfection contact tank 1 without stopping the tank.

[0021] The mobile vehicle body 2 is equipped with a battery 9 that is connected to the electric slide 3, the lifting equipment 5, and the sludge pump 6 respectively. The sludge pump 6 is connected to the battery 9 via a cable 10. By setting the battery 9 to provide power to the electric slide 3, the lifting equipment 5, and the sludge pump 6, the power supply problem of the equipment on the mobile vehicle body 2 during the movement is solved. At the same time, the mobile vehicle body 2 can be an electric mobile trolley, and the battery 9 is also electrically connected to the mobile vehicle body 2 to meet the power supply needs of the mobile vehicle body 2.

[0022] The sludge pump 6 is equipped with a suction pipe 8 extending to the outside of the disinfection contact tank 1 at its discharge end. The mobile platform 17 is equipped with two sets of clamping parts 11 located on both sides of the lifting equipment 5. The suction pipe 8 and the cable 10 pass through the through groove 4 and are engaged with the two sets of clamping parts 11. The clamping parts 11 are equipped with annular rubber sleeves 12. The suction pipe 8 and the cable 10 are in contact with the inner rings of the two sets of rubber sleeves 12. By setting the suction pipe 8 and the cable 10 to pass through the through groove 4 and be engaged with the two sets of clamping parts 11, the suction pipe 8 and the cable 10 can be effectively fixed. At the same time, the suction pipe 8 and the cable 10 are located on both sides of the lifting equipment 5, which can effectively separate the chain, suction pipe 8, and cable 10 at the lifting end of the lifting equipment 5 during the movement of the mobile platform 17, so as to avoid them from getting tangled and affecting the service life of the equipment.

[0023] An installation frame 14 is installed inside the suction hood 7. The installation frame 14 is located between the suction end of the sludge pump 6 and the suction window 13. Multiple sets of blades 15 are installed on the installation frame 14 at equal intervals. The blades 15 are rotatably connected to the installation frame 14. By setting multiple sets of blades 15 rotatably connected to the installation frame 14, the blades 15 rotate under the action of the water flow sucked in by the sludge pump 6, effectively breaking up the clumps of sludge, avoiding the clumps of sludge from clogging the suction end of the sludge pump 6, and improving the sludge cleaning effect.

[0024] The suction hood 7 is tapered, narrower at the top and wider at the bottom. This design enhances the suction force of the sludge pump 6 on the sludge at the bottom of the disinfection contact tank 1. The bottom of the suction hood 7 is reinforced with ribs 16, which strengthen the bottom of the hood and prevent damage from collisions with the inner wall of the disinfection contact tank 1. The mobile vehicle 2 is equipped with a controller connected to the electric slide 3, lifting equipment 5, and sludge pump 6. This controller is connected to an external handheld terminal, allowing for remote operation of the electric slide 3, lifting equipment 5, and sludge pump 6, eliminating safety risks associated with complex working environments.

[0025] The working process of this utility model is as follows: First, the operator uses an external handheld terminal to control the lifting equipment 5 to lower the sludge pump 6 to the bottom of the disinfection contact tank 1. The sludge pump 6 is then started to pump the sludge from the bottom of the disinfection contact tank 1. Under the action of the water flow sucked in by the sludge pump 6, the blades 15 rotate, effectively breaking up the clumps of sludge and preventing the clumps from clogging the suction end of the sludge pump 6. The pumped sludge is discharged through the suction pipe 8 to the external sludge treatment equipment for processing. The lifting equipment 5 can adjust the position of the sludge pump 6 according to the different depths of the disinfection contact tank 1. Then, the electric slide 3 first drives the moving platform... The lifting equipment 5, suction pipe 8, and cable 10 on platform 17 move laterally along the disinfection contact pool 1. At the same time, the sludge pump 6 moves synchronously to suction sludge under the action of the lifting equipment 5. After the lateral suction is completed, the moving vehicle 2 drives the entire equipment to move longitudinally along the disinfection contact pool 1. The moving vehicle 2 stops after moving a certain distance. The distance moved depends on the suction area of ​​the sludge pump 6. The electric sliding table 3 drives the lifting equipment 5, suction pipe 8, and cable 10 on the moving platform 17 to move laterally along the disinfection contact pool 1 again to complete the next cleaning. Repeating the above steps can complete the overall cleaning of the disinfection contact pool 1.

[0026] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
