Description

Technical Field

[0001] This utility model relates to the field of cleaning system technology, specifically a cleaning system for the inner wall of a large storage tank. Background Technology

[0002] In the petroleum and chemical industries, large storage tanks are widely used to store various liquid or gaseous media. Over time, dirt, rust, and other impurities accumulate on the inner walls of these tanks, reducing their lifespan and safety. Therefore, it is necessary to flush and maintain the inner walls of large storage tanks.

[0003] Washing the storage tanks generates a lot of wastewater containing sludge and impurities. The current method for treating wastewater and impurities is to discharge the wastewater into a temporary pool, let it dry naturally to evaporate the wastewater, leaving behind dried sludge, which is then treated. This self-heating drying method is time-consuming, inefficient, and the evaporation of wastewater pollutes the environment. Utility Model Content

[0004] The main purpose of this utility model is to provide a large storage tank inner wall cleaning system to solve the problem that the wastewater generated after tank washing is treated by self-ignition and drying in the prior art, which takes a long time, is inefficient, and the evaporation of wastewater will pollute the environment.

[0005] To achieve the above objectives, this utility model provides a large storage tank inner wall cleaning system, including a large storage tank, a sludge removal robot, a filter press, and a vacuum truck; the sludge removal robot is capable of rinsing and vacuuming the bottom of the large storage tank, and is located inside the large storage tank. The sludge removal robot is connected to the inlet of the filter press through a pipe, and the filtrate outlet of the filter press is connected to a storage tank through a pipe; the inlet of the vacuum truck is connected to the storage tank through a pipe.

[0006] Furthermore, the vacuum truck includes a transport vehicle, on which a vacuum tank is installed; one end of the vacuum tank is hinged to the transport vehicle, and the other end is connected to an angle hydraulic rod for adjusting the angle of the vacuum tank; the vacuum tank is connected to a vacuum pump through a pipe, and the vacuum tank is equipped with an inlet and an outlet.

[0007] Furthermore, the transport vehicle is equipped with a cleaning tank, which is connected to the inlet of a plunger pump via a pipe, and the outlet of the plunger pump is connected to a cleaning pipe.

[0008] Furthermore, the transport vehicle is equipped with a generator, which is connected to a vacuum pump and a plunger pump via wires.

[0009] Furthermore, it also includes an interior cleaning robot for flushing the sidewalls of large storage tanks, located inside the large storage tanks.

[0010] This invention features a sludge-dredging robot for rinsing and vacuuming the bottom of large storage tanks; a filter press for separating wastewater and sludge; a storage tank for temporarily storing the filtered wastewater; and a vacuum truck for pumping wastewater to a wastewater treatment plant.

[0011] This invention enables rapid separation of sewage and sludge, rapid drying of sludge, high treatment efficiency, and avoids environmental pollution caused by sewage evaporation.

[0012] This invention, by incorporating an internal cleaning robot, can flush the side walls of the storage tank without requiring workers to enter the tank for cleaning. This avoids threats to the lives of construction workers posed by dangerous factors such as flammable, explosive, toxic, and harmful gases and oxygen deficiency inside the tank.

A suction pump is connected to the suction pipe 201; a nozzle 204 is connected to the front end of the high-pressure flushing pipe 203, and a sludge-removing water tank 7 is connected to the rear end; the sludge-removing robot 2 can flush and suction the bottom of the large storage tank 1, and the sludge-removing robot 2 is located inside the large storage tank 1; the suction pipe 201 of the sludge-removing robot 2 is connected to the inlet of the filter press 3 through a pipe, and the filtrate outlet of the filter press 3 is connected to the storage tank 6 through a pipe. The filter press 3 is a chamber filter press; the inlet of the suction truck 4 is connected to the storage tank 6 through a pipe.

[0017] The vacuum truck 4 includes a transport vehicle 401, on which a vacuum tank 402 is installed. The right end of the vacuum tank 402 is hinged to the transport vehicle 401, and the left end is connected to an angle hydraulic rod 403 for adjusting the angle of the vacuum tank 402. The two ends of the angle hydraulic rod 403 are respectively hinged to the transport vehicle 401 and the vacuum tank 402. The vacuum tank 402 is connected to a vacuum pump 404 through a pipe. The top of the vacuum tank 402 is provided with an inlet 405, and the bottom right end is provided with an outlet 406. The angle hydraulic rod 403 can lift the left end of the vacuum tank 402, so that the sewage is discharged from the outlet 406 under the action of gravity. The vacuum pump 404 is used to evacuate the vacuum tank 402, so that the vacuum tank 402 can perform sewage suction under negative pressure.

[0018] The transport vehicle 401 is equipped with a cleaning tank 407. The cleaning tank 407 is connected to the inlet of a plunger pump 408 through a pipe, and the outlet of the plunger pump 408 is connected to a cleaning pipe. When the sludge suction work is completed, the plunger pump 408 draws out the water in the cleaning tank 407 to rinse the ground and keep the ground clean.
