Description

Technical Field

[0001] The invention relates to intelligent filling equipment for gasoline barrels, and belongs to the field of filling equipment for volatile, flammable and explosive liquids. Background Art

[0002] With the development of industry and the improvement of residents' living standards, filling machines have been widely used in many fields. However, at present, most companies use manual filling to complete the filling process of gasoline into gasoline barrels. This filling efficiency is extremely low, and the gas emitted by gasoline is harmful to the human body and will cause environmental pollution.

[0003] In recent years, the decline in the proportion of the labor force and the continuous increase in workers' wages have indirectly increased production costs, which has affected the economic benefits of enterprises to a certain extent. Therefore, it is necessary to adopt advanced production equipment to improve production efficiency and reduce the number of employees to reduce production costs. In order to solve the problems of slow operation speed and low efficiency of the filling station, it is necessary to optimize the design of the original filling line to improve work efficiency.

[0004] Therefore, studying a fully automatic intelligent filling system for gasoline barrels not only reduces the consumption of human resources and improves filling efficiency, but also reduces the volatilization of pollutants into the air, achieving the effect of energy conservation and emission reduction. It has very important theoretical significance and practical value. Summary of the invention

The activated carbon adsorption device is connected to the closed workshop through the first air pump, the adsorption box with replaceable activated carbon and the gas storage tank, and the first throttle valve is set. The data monitored by the gasoline volatile gas concentration sensor is transmitted to the PLC end to control the flow of the air pump and the throttle valve, so that the volatile gas enters the gas storage tank after adsorption treatment in the adsorption box, ensuring that the gasoline volatile gas concentration in the closed workshop is lower than the safety value, reducing air pollution, and achieving the purpose of energy conservation, emission reduction and green environmental protection.

The carbon dioxide concentration sensor 29 and the gasoline volatile gas concentration sensor 30 respectively detect the carbon dioxide concentration and the gasoline volatile gas concentration to ensure that the carbon dioxide concentration is higher than the set value and the gasoline volatile gas is lower than the set value.

[0024] The conveying device 2 of this embodiment includes two conveyor belts for conveying gasoline barrels and two conveying motors 14 for driving the conveyor belts to perform reciprocating linear motion. The two conveyor belts are respectively a first conveyor belt 12 and a second conveyor belt 13. Each conveyor belt is provided with a pressure sensor 15, and the pressure sensor 15 is arranged at the center position of the conveyor belt; when the gasoline barrel reaches the position of the pressure sensor 15, the conveyor belt will stop conveying to facilitate the next filling step.

[0025] The filling system 3 of this embodiment adopts an automatic filling device with an OpenCV visual recognition function.

The activated carbon adsorption device 4 receives the value of the gasoline volatile gas concentration sensor 30, controls the air pump and the throttle valve flow through the PLC end, to ensure that the gasoline volatile gas concentration in the closed workshop is lower than its safety value, otherwise the filling is stopped, and the gas adsorbed by the activated carbon enters the gas storage tank through the gas pipeline. The gasoline volatile gas concentration sensor 30 detects the concentration of gasoline volatile gas inside the closed workshop 1 in real time. If it is higher than the set value, the first air pump 8 and the first throttle valve 25 in the activated carbon adsorption device 4 are controlled through the PLC end to extract the mixed gas in the closed workshop 1 through the first gas hose 24 and then enter the gas storage tank 10 after adsorption by the adsorption box 9 until the concentration of gasoline volatile gas inside the closed workshop 1 is lower than the set value.

[0028] The carbon dioxide delivery system 5 of this embodiment includes a carbon dioxide gas cylinder 11 and a second air pump 26 for delivering a fixed amount of carbon dioxide to the closed workshop 1. The second air pump 26, the carbon dioxide gas cylinder 11 and the closed workshop 1 are connected by a second air delivery hose 27, and a second throttle valve 28 is set at the connection between the second air delivery hose 27 and the closed workshop 1.

[0029] Working principle: The rotating disk 19 is fixed at both ends of the fixed beam 31 of the closed workshop 1, and its position is aligned with the center of the two conveyor belts. The servo motor 20 is fixed on the fixed beam 31 of the closed workshop 1.

The vacuum suction cup 17 and the oil delivery gun 18 are respectively at both ends of the rotating disk 19, and are on the same concentric circle with the rotating disk 19, with an angle of 180 degrees. The concentric circle where the vacuum suction cup 17 and the oil delivery gun 18 are located is aligned with the center of the barrel mouth. The vacuum pump 16 is fixed on the rotating disk 19 to grab the barrel cover. The oil delivery hose 21 is connected to the oil delivery gun 18 through a rotary joint 35. When the gasoline barrel reaches the position of the pressure sensor 15, the transmission The belt stops moving, the servo motor 20 starts to control the rotation of the rotating disk 19, the industrial camera 22 identifies the position of the barrel mouth, and makes the vacuum suction cup 17 accurately align with the position of the barrel mouth. When the two sets of equipment locate the position of the barrel mouth at the same time, the motor 23 controls the vacuum suction cup 17 to descend to contact with the barrel cover, and the vacuum pump 16 controls the vacuum suction cup 17 to absorb the barrel cover. Finally, the motor 23 drives the vacuum suction cup 17 to rise. After receiving the command, the servo motor 20 controls the rotating disk 19 to rotate 180 degrees, so that the oil delivery gun 18 is aimed at the barrel mouth and starts to fill oil. At this time, the value of the pressure sensor 15 is detected. After reaching the specified filling value, the filling is ended. Repeat the above steps to cover the barrel cover and end the filling. Finally, the conveyor belt sends the filled oil barrel out of the workshop, and the filling work is completed.
