Technical Field

[0001] The invention relates to the technical field of automatic tank cleaning, in particular to an automatic tank cleaning device. Background Art

[0002] According to the management regulations of underground storage tanks at gas stations, in order to ensure the quality of oil products sold, the underground storage tanks at gas stations must be cleaned every 3-5 years. At present, most of the cleaning of underground storage tanks at gas stations is a construction mode of manual tank cleaning. Since there is a large amount of organic gas in the storage tank, the ventilation of the buried storage tank remains unchanged, and forced ventilation is also difficult to completely discharge the flammable and explosive organic gas. In addition, manual cleaning requires a large amount of clean water consumption, and a large number of pollution sources are formed at the same time, which increases the load and cost of enterprise sewage treatment. Therefore, those skilled in the art provide a storage tank automatic cleaning device to solve the problems raised in the above background technology. Summary of the invention

[0021] The sealing cover 6 is connected to the outlet 2 of the storage tank 1 through a flange, and a rubber plug matching the outlet 2 is provided on the lower side of the sealing cover 6 for sealing to prevent internal gas leakage. A centrifugal pump 7 is installed on the water inlet pipe 3 on the upper side of the sealing cover 6, and an oil-water separation device, an exhaust gas treatment device and a water pump are connected to the upper end of the water outlet pipe 4. The water pump is connected in parallel with the oil-water separation device and the exhaust gas treatment device, and the water pump is connected to a collecting device. A three-way valve 5 is installed between the water inlet pipe 3 and the water outlet pipe 4, and a solenoid valve is installed on the upper end of the water inlet pipe 3. A roller is provided at the lower end of the support pipe 12, and a reinforcement member 11 is installed at the connection between the support pipe 12 and the hose 9. An umbrella-shaped nozzle is provided on the upper side of the reinforcement member 11. A fixing rod 8 is fixed to the middle of the water inlet pipe 3 and the water outlet pipe 4, and a connecting wire 19 is wound around the fixing rod 8. The lower ends of the connecting wire 19 are respectively connected to the cleaning head 10, the cleaning disc 13 and the reinforcement member 11 for easy fixation;

[0022] The cleaning head 10 includes a nozzle at the end and bent tubes 16 distributed around. The cleaning disc 13 is provided with through holes at the top, bottom, front and back. The outer side of the through hole is rotatably connected with a rotating member 17. The outer side of the rotating member 17 is slidably connected in a clamping ring 18. The rotating shaft of the rotating member 17 is connected to the pipeline of the cleaning disc 13 through a bearing. The rotating member 17 is a semicircular baffle. A plurality of arc-shaped grooves are distributed on the inner side of the semicircular baffle. When the water flows through the rotating member 17, it is blocked by the baffle of the rotating member 17 and sprayed out through the other semicircle. At the same time, the arc-shaped groove changes the direction of the water flow, driving the rotating member 17 to rotate, so as to achieve the purpose of changing the impact force of the water flow and intermittent spraying.

The porous material absorbs grease and cleaning liquid, and the float keeps the oil suction plate 14 always on the surface of the liquid.

[0024] The working principle of the present invention is as follows: when in use, the device is placed into the storage tank 1 through the outlet 2, the outlet 2 is sealed by the cover 6, the centrifugal pump 7 is activated, water enters the storage tank 1 through the water inlet pipe 3, the water flows into the cleaning head 10 and the cleaning plate 13 through the hose 9, and is sprayed onto the inner wall of the storage tank 1. At the same time, through the effect of water pressure, the hose 9 gradually straightens, driving the reinforcement 11 and the cleaning head 10 to disperse in the storage tank 1, and the washed oil and water enter the oil-water separator through the oil suction plate 14. After a period of time, When the oil in the storage tank 1 is judged by the oil-water separator to be insufficient for collection, the concentrated cleaning liquid is introduced through the water inlet pipe 3. After an appropriate amount is introduced, the solenoid valve of the water inlet pipe 3 is closed, and the three-way valve 5 is opened to connect the water inlet pipe 3 and the water outlet pipe 4. Through repeated circulation and cleaning of water flow, all-round cleaning is achieved. After cleaning, the centrifugal pump 7 is closed, the cover 6 is opened, and the water pump is connected through the water outlet pipe 4 to absorb the cleaning liquid in the storage tank 1, and water is introduced again through the water inlet pipe 3 until the predetermined cleaning effect is achieved.

[0025] The present invention avoids manual entry into the storage tank 1, and uses a pre-exhaust gas treatment device and an oil-water separation device to prevent the exhaust gas in the storage tank 1 from polluting the environment during cleaning, thereby recycling the waste oil. At the same time, the interior of the storage tank 1 is fully flushed through a hose 9, a cleaning head 10 and a cleaning plate 13, with a good cleaning effect and without introducing other pollutants.
