step four, secondary air inlet of the sedimentation tank
When the first valve of the first air inlet part 14 is opened and the second valve of the second air inlet part 15 is opened simultaneously, air is fed into the sedimentation tank 11, the cleaning particles 13 move upwards in a biased manner to one side under the blowing of the bubbles generated by the first air inlet part 14 and the second air inlet part 15, namely: the cleaning particles 13 are deflected and move upwards towards the left side surface of the inclined tube, so that the cleaning particles 13 are in frictional contact with the left side surface of the inclined tube assembly 12, after air inlet is stopped, the cleaning particles 13 are in frictional contact with the left side surface of the inclined tube assembly 12 again under the action of gravity, and then the cleaning particles return to the storage chamber 111;
step five, feeding air for the third time into the sedimentation tank
When the first valve of the first air inlet part 14 is opened and the third valve of the third air inlet part 16 is opened simultaneously, air is fed into the sedimentation tank 11, the cleaning particles 13 move upwards towards the other side by being deflected under the blowing of the bubbles generated by the first air inlet part 14 and the third air inlet part 16, namely: the cleaning particles 13 are in friction contact with the right side surface of the inclined tube assembly 12 after air inlet is stopped, and the cleaning particles 13 are in friction contact with the right side surface of the inclined tube assembly 12 again under the action of gravity and then return to the storage chamber 111;
step six, draining the sedimentation tank for the second time
And repeating the third step to the fifth step for many times, after the inclined pipe assembly 12 is cleaned and reaches an ideal cleaning degree, opening the drain pipe 17 of the sedimentation tank 11, discharging sewage in the sedimentation tank, completely discharging sediments in the sedimentation tank 11, and finishing the cleaning process.
In the actual operation process, the cleaning times can be adjusted as required, the inclined tube assembly 12 is cleaned, the normal work of the inclined tube assembly 12 is not affected, and the cleaning requirement can be met after cleaning for ten minutes generally.
Further, the first air intake portion 14, the second air intake portion 15, and the third air intake portion 16 all receive compressed air.
The specific gravity of the cleaning particles 13 is greater than that of water, the cleaning particles need to sink to the bottom of the water, and the pressure of compressed air is high, so that the compressed air is used as a power source, after being input into the sedimentation tank 11, the compressed air provides driving force for the upward movement of the cleaning particles 13, the cleaning particles 13 can be quickly blown upwards, and the cleaning particles 13 are in frictional contact with the inclined tube assembly 12.
Further, the specific gravity of the cleaning particles 13 is 1.1-1.5 g/cm3。
The cleaning particles 13 may be light microporous ceramic particles having a specific gravity of 1g/cm3The specific gravity of the cleaning particles 13 is required to be larger than that of water, and other cleaning materials can be selected as long as the specific gravity is 1.1-1.5 g/cm3When the first air intake part 14, the second air intake part 15 and the third air intake part 16 are used for air intake, the cleaning particles 13 can float to the position of the water surface under the driving of the air bubbles, thereby meeting the cleaning requirement.
According to the cleaning method of the inclined tube sedimentation tank cleaning device, sediment in the sedimentation tank is discharged before cleaning, then the vertical air inlet mode, the left air inlet mode and the right air inlet mode are respectively adopted, the surface of an inclined tube is respectively cleaned in a friction mode from multiple directions, so that cleaning particles are collided and rubbed with the surface of the inclined tube, the surface of an inclined tube assembly is cleaned, the cleaning process is simple, manual intervention is less, and the cleaning efficiency is improved.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
