Description

Technical Field

[0001] This invention belongs to the field of fluid transport equipment technology, specifically an integrated washing tank pipeline with a drive structure. Background Technology

[0002] Railway tank cars, as an important tool for transporting liquid materials, are widely used in the petroleum, chemical, and liquid food industries. With the rapid development of these industries, the number of railway tank cars is increasing year by year. For such a large number of tank cars, the internal cleaning work before each depot overhaul, factory overhaul, and material change is particularly arduous. Statistics show that each tank car needs to be cleaned at least twice a year, and given the vast number of railway tank cars nationwide, the cleaning workload is enormous.

[0003] Currently, there are numerous car washing stations in China, but most still employ traditional manual washing techniques. This process requires workers to enter the confined space of the tank and use handheld hoses to spray hot water onto the tank walls. To improve cleaning effectiveness, a steam treatment process is introduced after the hot water rinse. In this process, workers need to insert a steam hose into the tank through the opening and introduce steam at 0.6–0.8 MPa to heat and remove residues and sludge. However, all these operations are carried out with the tank opening open, which is not only labor-intensive and inefficient but also energy-intensive and costly.

[0004] More seriously, the residual materials inside the tanks are often flammable, explosive, toxic, and harmful, and are prone to volatilization and accumulation. Without adequate protective measures, workers entering poorly ventilated tanks are highly susceptible to poisoning and asphyxiation. Furthermore, static electricity from the human body can trigger flash explosions of flammable gases, making manual cleaning a highly dangerous task.

[0005] Meanwhile, due to the unsealed tank openings, a large amount of steam carrying volatile gases escapes, causing environmental pollution. With increasing environmental awareness, the environmental issues related to railway tank car cleaning urgently need to be addressed. Therefore, developing a cleaning technology that is both environmentally friendly and safe, while also reducing the labor intensity of workers, is both a national need and an urgent requirement for enterprise development.

[0006] To address the aforementioned issues, Chinese utility model patent CN202122171303.8 discloses a steam cleaning tank sealing device. This invention overcomes the problem of sealing the tank opening and integrates the steam pipe and sewage discharge into the equipment, achieving a sealed effect for both steam cooking and sewage discharge processes. However, this invention only seals the steam cooking and sewage discharge processes; the hot water rinsing and hot air blowing processes still require the tank lid to be open for manual operation. It neither avoids manual entry into the tank for cleaning nor achieves a fully sealed cleaning process. Furthermore, the steam nozzle used in this invention has a fixed structure with a short range, unable to penetrate deep into the sides of the tank, resulting in poor steam cleaning effect. Summary of the Invention

[0007] The purpose of this invention is to provide an integrated washing tank pipeline with a drive structure to achieve a fully enclosed process for hot water rinsing, steam cleaning, and sewage discharge ventilation. This solves the cleaning problems such as the flammability, explosiveness, toxicity, and easy volatilization of residual materials in the tank, the risk of poisoning and suffocation for workers entering poorly ventilated tanks when protection is inadequate, the high risk of manual cleaning due to static electricity or flash explosions caused by human body, and the leakage of steam and volatile gases from unsealed tank openings, which pollute the environment.

[0054] In one embodiment, a return air tee pipe 2 is also provided on the pressure plate 20.

[0055] In one embodiment, a clamp 5 is provided on the outer tube 18, and nozzle assemblies 17 are provided on both sides of the bottom of the outer tube 18. Steam and nitrogen outlet pipes 13 are connected to the nozzle assembly 17 and pass through the pressure plate 20.

[0057] In one embodiment, the tank washing process is as follows: First, the integrated tank in the recycling state is moved to the top of the tank opening. At this time, the gate component 1.14 is in the position of the nozzle assembly 17. The tank sweeping telescopic tube locking buckle 15 is manually rotated and opened. The tank sweeping motor drive assembly 16 is lowered to the bottom under the action of gravity. Compressed gas is introduced into the motor 3.1 to make the gun bolt assembly 3.4 rise and lock the tank opening, ensuring that the sealing component is completely sealed to the tank opening.

[0058] Compressed gas is then introduced into limit valve mechanism 1.222 and limit valve mechanism 1.223. The compressed gas passes through limit valve mechanism 1.222 and limit valve mechanism 1.223 and enters pneumatic motor 1.42. Pneumatic motor 1.42 drives drive gear 1.421 to rotate. Drive gear 1.421 drives driven gear 1.58 and driven gear 1.59 to rotate. Driven gear 1.58 drives transmission screw 1.11 to rotate. Driven gear 1.59 drives transmission screw 1.112 to rotate.

[0059] Ventilation is introduced into the open limit valve mechanism 1.222. Simultaneous rotation of drive screws 1.11 and 1.112 causes the gate component 1.14 to move downward. The rotation of drive screw 1.11 gradually closes the limit valve mechanism 1.222, while the rotation of drive screw 1.112 gradually opens the limit valve mechanism 1.223.

[0060] Ventilation is introduced into the open limit valve mechanism 1.223. Simultaneous rotation of the transmission screws 1.11 and 1.112 causes the gate component 1.14 to move upward. The rotation of the transmission screw 1.11 gradually opens the limit valve mechanism 1.222, while the rotation of the transmission screw 1.112 gradually closes the limit valve mechanism 1.223.

[0061] Simultaneous rotation of drive screws 1.11 and 1.112 drives gate 1.14 downward, sealing the outlet of valve 181 and then the limit valve mechanism 1.222. The pneumatic motor 1.42 stops rotating as its air path is disconnected. At this point, steam and nitrogen outlet pipes 13 guide gas through inlet holes 1.144 on cylindrical pipe 1.143, into the pipe, through venting jacket 16.19, into the external vent pipe 16.1, and then into the motor vent seat 16.8, delivering the gas to the cleaning motor 16.11. The gas exits from the cleaning motor 16.11 and then through the silencer 16.9. Simultaneously, the cleaning motor 16.11 drives the cleaning impeller 16.7, drawing wastewater into the drain pipe and discharging it from the waste liquid / waste gas outlet 6. Hot water is first introduced into the synchronous hot air, hot water, steam, and nitrogen inlet 7. The hot water flows through the outer pipe 18 into the nozzle fixing assembly 17 and into the elbow 17.7. It is then sprayed out through the high-pressure rotating nozzle assembly 17.11 to clean the inner wall of the tanker. After the inner wall of the tanker is cleaned, the limit valve mechanism 1.223 is vented, driving the pneumatic motor 1.42 to reverse. The gate 1.14 is lifted in the reverse direction according to the above driving method, and the air valve 181 is released. At this time, hot air is introduced into the hot air, hot water, steam, and nitrogen inlet 7. The hot air flows out from the side hole of the air valve 181 and sprays into the tank. The hot air carries the water vapor in the tank out through the outer pipe 18 and elbow 2.2 and is discharged outside the tank. The water vapor in the tank is then pumped out by the external pump.

[0062] Throughout the process, the sealing device and the tank opening are completely sealed, which greatly reduces the volatilization of oil and gas during cleaning and drying, thus reducing environmental pollution. At the same time, the entire intermediate process is controlled by the system, which greatly reduces the workload of manual operation and reduces the difficulty of operation.

[0063] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
