TECHNICAL FIELD

[0001] The present application relates to the technical field of tank car cleaning, in particular to a steam automatic cleaning system for chemical tank cars and a dosing control method thereof. BACKGROUND

[0002] The steam automatic cleaning system for chemical tank cars is a high-efficiency, safe and environmentally friendly cleaning solution. It realizes the dissolution and removal of residues in the tank through high-temperature and high-pressure steam, and combines automatic control, closed operation and environmental protection treatment technology to comprehensively improve the cleaning efficiency and safety.

[0003] In actual application, first, the inside of the oil tank is ventilated and the gas concentration in the tank is monitored to ensure a safe working environment; second, high-temperature steam is provided by a steam generator to penetrate every corner of the inside of the oil tank and soften stubborn stains; third, a high-pressure water jet technology (such as a three-dimensional rotary nozzle) is combined to perform 360° impact cleaning of the tank wall without dead angles; and finally, the tank body is dried by hot air, and solid waste and pretreated sewage are recovered and discharged in accordance with standards.

[0004] However, in the prior art, before the cleaning nozzle is lowered into the inside of the oil tank, the oil tank car may deviate from the established body station position when entering the cleaning area, resulting in deviation of the inlet of the oil tank from the descending track of the cleaning nozzle. Therefore, the worker needs to move above the tank body and manually pull the nozzle to align with the inlet. This behavior poses a safety hazard to the worker and also affects the cleaning efficiency.

[0005] In addition, for oil tanks of different sizes, the position height of the cleaning nozzle when lowered into the inside of the oil tank is generally a fixed height position. During the lowering process of the nozzle, the nozzle is slowly lowered by an electric hoist, and the current height position of the nozzle is marked by a laser level gauge, and the position height is repeatedly confirmed. This lowering step is relatively cumbersome and affects the cleaning efficiency.

[0037] As shown in Figures 3-5As shown, the translation assembly 2 includes a longitudinal moving plate 202 slidingly arranged on the top of the support frame body 1 and a longitudinal electric cylinder 201, the output end of the longitudinal electric cylinder 201 is connected with one side of the longitudinal moving plate 202, a sliding rail is arranged on the top beam of the support frame body 1, a sliding block 203 is slidingly arranged in the sliding rail, the bottom surface of the longitudinal moving plate 202 is uniformly provided with the sliding block 203, a transverse rail 204 is arranged in parallel on the bottom surface of the sliding block 203, and a transverse traveling wheel 205 is arranged in the transverse rail 204; one side of the transverse traveling wheel 205 is connected with a transverse translation motor 206, the end of the transverse translation motor 206 away from the transverse traveling wheel 205 is fixedly connected with a limiting block 207, a guide rod 208 is arranged on the side surface of the transverse rail 204, and the limiting block 207 is sleeved on the outside of the guide rod 208; a strip-shaped hole is formed in one side of the transverse rail 204, and the output shaft of the transverse translation motor 206 is fixedly connected with one side of the transverse traveling wheel 205 through the strip-shaped hole; the lifting assembly 3 includes an electric telescopic cylinder 301, the output end of the electric telescopic cylinder 301 is fixedly connected with a support table 302, the support table 302 is arranged on the top surface of the temporary cover plate 9, a connecting ring 303 is arranged on the top surface of the electric telescopic cylinder 301, the connecting ring 303 is rotatably sleeved on the outside of the transverse traveling wheel 205, and when the transverse traveling wheel 205 travels, the lifting assembly 3 can be driven to move as a whole through the connecting ring 303.

[0038] In use, after the oil tank truck is parked in the cleaning area, the staff checks the left and right offset direction and the front and back offset direction of the oil tank truck relative to the standard parking position range, so as to control the output end of the longitudinal electric cylinder 201 to stretch and retract in the direction opposite to the left and right offset direction through the remote control center, so as to drive the longitudinal moving plate 202 to reciprocate, and the longitudinal moving plate 202 drives the transverse rail 204 to reciprocate along the left and right direction through the sliding block 203; then the transverse translation motor 206 is controlled to rotate, the transverse traveling wheel 205 is driven to move along the transverse rail 204 in the direction opposite to the front and back offset direction, so that the lifting assembly 3 and the temporary cover plate 9 are driven to move to the approximate position above the inlet of the oil tank body 7 through the connecting ring 303, and the preliminary positioning is completed.

[0039] Then, the remote control center controls the output end of the electric telescopic cylinder 301 to elongate, so as to drive the support table 302 and the temporary cover plate 9 to descend, until the detection assembly 4 on the temporary cover plate 9 is in contact with the inlet end surface of the oil tank body 7, which represents that the temporary cover plate 9 has been lowered in place at this time, the remote control center stops the output end of the electric telescopic cylinder 301 from elongating, according to the offset direction fed back by the detection assembly 4, the longitudinal electric cylinder 201 and the transverse translation motor 206 are controlled for adjustment, so that the temporary cover plate 9 is coaxial with the inlet of the oil tank body 7, and the alignment of the two is completed.

[0040] Meanwhile, since the heights of the inlet end faces of the oil tank bodies 7 of different sizes are different, the height of the inlet end face of the current oil tank body 7 can be determined by the elongation of the output end of the electric telescopic cylinder 301, so that the diameter of the oil tank body 7 is determined, and then the descending height of the nozzle body 5 is determined. Therefore, the elongation of the output end of the electric telescopic cylinder 301 can be corresponded to the oil tank bodies 7 of different sizes and the distance that the nozzle body 5 needs to descend in the oil tank body 7 of different sizes in advance, and the corresponding data is stored in the database of the remote control center as comparison data, so that the remote control center can compare and judge the size of the oil tank body 7 subsequently.

[0041] After the remote control center judges the height that the nozzle body 5 needs to descend in the current oil tank body 7 to be cleaned, the control adjustment motor 603 is controlled to rotate clockwise, the adjustment motor 603 drives the lifting rack 601 to descend through the driving gear 604, and the lifting rack 601 drives the nozzle body 5 to descend to the corresponding height position through the limiting ring 602.

[0042] The working principle of the present application is as follows: first, preliminary positioning, the driver parks the oil tank truck in the cleaning area, the staff checks the left and right offset direction and the front and back offset direction of the oil tank truck relative to the standard parking position range, so that the front and back and left and right offset directions of the current oil tank body 7 relative to the standard parking position are determined, the output end of the longitudinal electric cylinder 201 is controlled to stretch and contract in the direction opposite to the left and right offset direction by the remote control center according to the front and back and left and right offset directions, so that the longitudinal moving plate 202 reciprocatingly moves, the longitudinal moving plate 202 drives the transverse track 204 to reciprocatingly move along the left and right direction through the sliding block 203; the transverse translation motor 206 is controlled to rotate, the transverse traveling wheel 205 is driven to move along the transverse track 204 towards the direction opposite to the front and back offset direction, so that the lifting assembly 3 and the temporary cover plate 9 are driven to move to the approximate position above the inlet of the oil tank body 7 through the adapter ring 303, and the preliminary positioning is completed.

[0043] Secondly, automatic accurate positioning, the output end of the electric telescopic cylinder 301 is controlled to elongate by the remote control center, so that the support table 302 and the temporary cover plate 9 descend until the pressure sensor 402 is subjected to pressure, which represents that the temporary cover plate 9 has descended in place at this time.
