Description

Technical Field

[0001] The invention relates to the technical field of connecting joints, and in particular to a quick-connector device for steam heat replenishment of oil unloading from a tank truck. Background Art

[0002] At present, some blocks mainly use tank trucks to transport crude oil, but the oil in these blocks has high viscosity, which leads to long unloading time and unclean unloading, resulting in shortage of crude oil vehicles and delays in production efficiency. Especially in low temperatures, such as in winter, the oil temperature needs to be increased when the tank truck is unloading so that the oil can flow out smoothly. In the Tahe work area, the oil unloading heating of the tank truck is done by manually passing a steam hose from the top of the tank truck on the trestle to the bottom of the tank truck to heat the crude oil.

[0003] The current oil unloading heating method has the following problems:

[0004] 1. During operation, workers need to stand at the top of the tanker and wear positive pressure air respirators. The operation is difficult and workers need to adjust the heating parts at any time. Then they need to move back and forth on the top of the tanker, which poses a great safety hazard.

[0005] 2. The operator needs to go on top of the vehicle to operate, and the unloading trestle is high from the ground; the operator's equipment is bulky, and there are safety hazards when going up and down the trestle;

[0006] 3. The steam pipe extends into the tank car, which has a large human factor, a long heating time, low efficiency, waste of energy and environmental pollution;

[0007] 4. Long oil unloading time and low utilization rate of tank trucks;

[0008] 5. High production cost.

[0009] Therefore, it is necessary to design a quick connector that is universal with the oil unloading port interface of the tank truck to solve the existing problems. Summary of the invention

[0010] The present invention aims to solve the problems in the prior art that when the existing tank truck steam heats the heavy oil, the heating steam pipeline is introduced into the tank truck from the top for heating, resulting in long heating time, low efficiency, waste of energy, environmental pollution, potential safety hazards for personnel, and low utilization rate of the tank truck. The present invention provides a quick joint device for steam heating of the oil tank truck unloading.

[0029] Example

[0030] Combination Figure 1As shown, this embodiment provides a quick joint device for steam heating of oil unloading in a tank truck, which includes a joint body 7 and a steam pipe 1. A cavity structure is provided inside the joint body 7. The steam pipe 1 runs from the front end of the joint body 7 to the inside of the cavity until it extends out from the rear end of the joint body 7. A front fixing ring 6 is provided at the front end of the cavity, and a rear fixing ring 8 is provided at the rear end of the cavity. The front fixing ring 6 is used to fix the front end of the steam pipe 1, and the rear fixing ring 8 is used to fix the rear end of the steam pipe 1. At the same time, an oil unloading port 5 is also provided between the front fixing ring 6 and the rear fixing ring 8. The oil unloading port 5 is connected to the inside of the cavity, and the outlet of the oil unloading port 5 is connected to the interface position of the corresponding oil unloading port 5 of the external tank truck. In some embodiments, the steam pipe 1 can preferably be a steam pipe 1 with a diameter of 25 mm and a length of 1200 mm, which can be inserted into the tank truck through the oil unloading port 5 by about 500-1000 mm.

[0031] In this embodiment, a gland 3 structure is provided at the end of the joint body 7, and the gland 3 is connected to the joint body 7 by welding or integral molding. A sealing filler 4 is provided inside the gland 3, wherein the sealing filler 4 is preferably a high-temperature resistant filler to ensure that no leakage occurs during operation. Furthermore, the steam pipe 1 passes through the inside of the gland 3; and a portable device can be further installed on the surface of the joint body 7 of the quick connector device to facilitate the installation of the equipment and the disassembly and assembly of personnel. A quick connector with an angle of 45° and a diameter of 100 mm is installed at the bottom of the quick connector portable device, that is, at the position corresponding to the oil drain port, which is used to connect to the oil unloading pipeline when unloading oil, so as to achieve heating and unloading of oil. It should be noted that the quick connector can select a DN100 quick connector.

[0032] In this embodiment, a gland 2 is also installed on the outside of the gland 3. The gland 2 is provided with a through hole and a mounting hole, and the through hole and the mounting hole are connected. The steam pipe 1 passes through the through hole and the mounting hole in sequence, and then passes through the gland 3 and the joint body 7, wherein the aperture of the mounting hole is larger than the aperture of the through hole, and a structure matching with the outside of the gland 3 is provided inside the mounting hole.

[0033] In this embodiment, a nozzle 9 is provided at the end of the steam pipe 1. Specifically, the steam pipe 1 is processed with a retractable structure. When it is not in operation, its contracted length is 500mm. When it is in operation, it can be extended to about 10000mm. A multi-point mesh nozzle is processed at the front end of the pipeline of the steam pipe 1. The straight section is the main nozzle. There are multiple irregular holes with a diameter of 5mm around the 100mm pipe wall at the front end of the pipeline. The nozzle 9 is set to spray neatly around to facilitate oil heating. Further, during operation, a 200KG / H gas steam generator (no monitoring and inspection is required) is equipped at the position of the oil drain port, and 0.7MPa steam is passed to the bottom of the tank truck through the oil unloading port 5, forming a temperature space with a radius of 500mm and a temperature of about 130℃ around the inside of the tank truck oil unloading port 5, thereby improving the fluidity of crude oil.

[0034] For example, according to the current single well S46 oil unloading process, 8 trucks are unloaded every day, an average of one truck every 3 hours. After the steam truck is used for heating and unloading, the efficiency of each heavy oil tank truck can be increased by 50% after the installation of the oil tank truck unloading steam heating quick connector device. The steam truck costs 340 yuan per hour and works 20 hours a day. The daily cost is 340×20=6800 yuan, the monthly cost is 6800×30=204,000 yuan, and the cost for three months is 20.4×3=612,000 yuan. The use of this device can save 612-30=312,000 yuan in three months.

[0035] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Simple modifications or equivalent substitutions of the technical solution of the present invention by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the present invention.
