DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Reference Figure 1-Figure 3 A condensate oil-liquid separation device comprises a collecting box 1, wherein the collecting box 1 is used to store condensate discharged from an external air compressor and a dryer.

[0020] The separation mechanism includes a partition 2 which is sealed and fixedly connected to the inner wall of the collection box 1. The partition 2 divides the collection box 1 into a first chamber 101 and a second chamber 102. A plurality of through holes 3 are opened at the lower end of the partition 2. An electric plate-type butterfly valve 4 is installed in the through hole 3.

[0021] The upper end of the collecting box 1 is rotatably connected to a box cover 15 via a rotating shaft. The side wall of the box cover 15 located above the first chamber 101 is fixedly connected to a delivery pipe 16. The side wall of the delivery pipe 16 away from the box cover 15 is sealed and rotatably connected to a nut 17. The nut 17 is connected to the water outlet pipe of the external air compressor and the dryer.

[0022] Furthermore, the condensed water discharged from the air compressor and the dryer is stored in the collection box 1. Since the density of oil is smaller than that of water, the oil floats on the water. When the condensed water stored in the first chamber 101 reaches a certain content, the electric plate butterfly valve 4 opens, so that part of the condensed water in the first chamber 101 will enter the second chamber 102, while the oil located on the surface of the water is still located in the first chamber 101, thereby realizing the separation of oil and water in the condensed water, avoiding the fact that there is no systematic wastewater treatment device for the condensed water of the air compressor in the prior art, resulting in a certain impact on the environment caused by the directly discharged condensed water.

[0023] It also includes an extraction mechanism, which includes an oil pump 5 and a water pump 9 fixedly connected to the side wall of the collecting box 1 through a bracket, the input end of the oil pump 5 is fixedly connected to an oil suction pipe 6, and the output end of the oil pump 5 is fixedly connected to an oil outlet pipe 8 for extracting oil from the condensed water, a placement plate 7 is fixedly connected to the side wall of the collecting box 1, the oil suction pipe 6 is located on the placement plate 7, the input end of the water pump 9 is connected to the inner wall of the collecting box 1 through a water suction pipe 10, the end of the water suction pipe 10 away from the water pump 9 is close to the bottom of the second chamber 102, and the output end of the water suction pipe 10 is fixedly connected to a drain pipe 11 for extracting the separated condensed water.

[0024] A first liquid level gauge 12 is installed on the inner wall of the first chamber 101, a second liquid level gauge 13 and a third liquid level gauge 14 are installed on the inner wall of the second chamber 102, the third liquid level gauge 14 is located below the second liquid level gauge 13, the first liquid level gauge 12 and the electric plate butterfly valve 4 are electrically connected to the external power supply through a PLC control mechanism, the second liquid level gauge 13 and the water pump 9 are electrically connected to the external power supply through a PLC control mechanism, and the third liquid level gauge 14 and the water pump 9 are electrically connected to the external power supply through a PLC control mechanism.

[0025] Furthermore, when the collecting box 1 is first used, the electric plate type butterfly valve 4 is closed. When the condensed water in the first chamber 101 is collected and reaches the first liquid level gauge 12, the external PLC control mechanism will open the electric plate type butterfly valve 4 through an external power supply to prevent the electric plate type butterfly valve 4 from opening at the beginning, causing the oil in the condensed water to partially enter the second chamber 102, and the process continues. Subsequently, the condensed water in the first chamber 101 will partially enter the second chamber 102. Then, as the condensed water in the collecting box 1 increases and the condensed water in the second chamber 102 reaches the second liquid level gauge 13, the external PLC control mechanism will start the water pump 9 through an external power supply, and the condensed water in the second chamber 102 can be discharged through the water suction pipe 10 and the drainage pipe 11. When the condensed water in the second chamber 102 drops below the third liquid level gauge 14, the water pump 9 is turned off and continues to store water in the second chamber 102.

[0026] In the above process, the PLC control mechanism controls the power connection control method of the electric plate butterfly valve 4 and the water pump 9 according to the conditions of the first liquid level gauge 12, the second liquid level gauge 13 and the third liquid level gauge 14, which are all existing technologies and will not be described here.

[0027] The working principle of the utility model is:

[0028] First, the delivery pipe 16 is connected to the water outlet pipe of the external air compressor and the dryer through the nut 17, so that the condensed water discharged from the external air compressor and the dryer can be stored in the first chamber 101;

[0029] When the condensed water in the first chamber 101 is collected to reach the first liquid level gauge 12, the external PLC control mechanism will open the electric plate butterfly valve 4 through the external power supply, and the process continues. At this time, the condensed water in the first chamber 101 will partially enter the second chamber 102 through the through hole 3, while the oil on the surface of the water is still in the first chamber 101, so as to achieve the separation of oil and water in the condensed water;

[0030] As the condensed water in the collection box 1 increases, when the condensed water in the second chamber 102 reaches the second liquid level gauge 13, the external PLC control mechanism will start the water pump 9 through the external power supply, and the condensed water in the second chamber 102 can be discharged through the suction pipe 10 and the drainage pipe 11. When the condensed water in the second chamber 102 drops below the third liquid level gauge 14, the water pump 9 is turned off and water continues to be stored in the second chamber 102.

[0031] When the oil floating on the surface of the water in the first chamber 101 needs to be processed, the box cover 15 is flipped upwards, and then the staff holds the oil suction pipe 6 and enters the oil, starts the oil pump 5, and then the oil can be pumped out.

[0032] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
