Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to an oil depot wastewater treatment device. Background Technology

[0002] Aviation fuel depots, which handle the receipt, dispatch, and storage of aviation fuel, are facilities that provide refueling services to general aviation aircraft. The wastewater generated during their transfer and operation increases accordingly. Furthermore, the increasing complexity of fuel types leads to more complex compositions in the wastewater, resulting in large volumes and high levels of pollution. However, if the wastewater is heavily polluted, containing a high proportion of particulate matter, the excessive pollution places a heavy burden on subsequent treatment processes, leading to high wastewater treatment costs. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies, such as the high degree of water pollution, the presence of particulate matter in the wastewater, the excessive pollution of the water body, the heavy burden on subsequent treatment processes, and the high cost of wastewater treatment. Therefore, this invention proposes an oil depot wastewater treatment device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Design an oil depot wastewater treatment device, comprising a main body, with support columns arranged around the bottom of the main body, a shell connected to the middle of the bottom of the main body, the shell being in communication with the main body, a sewage pipe connected to the bottom of the shell, a drain pipe connected to one side of the bottom of the main body, a first support frame arranged on the top of the main body, and a second support frame arranged on the top of the shell, a rotating rod arranged on the first support frame via bearings, a rotating shaft arranged on the second support frame via bearings, a plurality of crushing rollers arranged on the rotating rod, rotating blades arranged on the rotating shaft, a connecting assembly arranged between the rotating rod and the rotating shaft, a servo motor arranged on the first support frame, and the output shaft of the servo motor being connected to one end of the rotating rod.

[0006] Preferably, the bottom of the housing is inclined.

[0007] Preferably, the connecting assembly includes a through groove formed on the second support frame, a connecting rod disposed in the through groove via a bearing, a first gear disposed on one end of the connecting rod and one end of the rotating rod, the two first gears meshing with each other, and a second gear disposed on the outer side of the other end of the connecting rod and one end of the rotating shaft, the two second gears meshing with each other.

[0008] Preferably, one end of the rotating rod is connected to the second support frame via a bearing.

[0009] Preferably, both the first gears and both second gears have a corrosion-resistant coating on their outer sides.

[0010] The present invention proposes an oil depot wastewater treatment device, which has the following advantages: the device uses a rotating rod to drive the rotation of several crushing rollers, thereby separating oil and water in the wastewater. Furthermore, the particulate matter in the wastewater settles and is aggregated by the rotating blades, reducing the amount of oil in the wastewater flowing out of the drain pipe. This reduces the degree of water pollution, alleviates the burden on subsequent treatment processes, and lowers energy costs. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Example 1: Refer to Figure 1-4An oil depot wastewater treatment device includes a main body 1, with support columns 2 arranged around the bottom of the main body 1. A shell 3 is connected to the middle of the bottom of the main body 1 and is in communication with the main body 1. A sewage pipe 4 is connected to the bottom of the shell 3, and a drain pipe 5 is connected to one side of the bottom of the main body 1. A first support frame 6 is arranged on the top of the main body 1, and a second support frame 7 is arranged on the top of the shell 3. A rotating rod 8 is mounted on the first support frame 6 via bearings, and a rotating shaft 9 is mounted on the second support frame 7 via bearings. Several crushing rollers 10 are arranged on the rotating rod 8, and rotating blades 11 are arranged on the rotating shaft 9. A connecting assembly is provided between the rotating rod 8 and the rotating shaft 9. A servo motor 12 is provided on the first support frame 6. The output shaft of the servo motor 12 is connected to one end of the rotating rod 8. The connecting assembly includes a through groove 13 opened on the second support frame 7. A connecting rod 14 is provided in the through groove 13 through a bearing. A first gear 15 is provided on one end of the connecting rod 14 and one end of the rotating rod 8. The two first gears 15 mesh with each other. A second gear 16 is provided on the outer side of the other end of the connecting rod 14 and one end of the rotating shaft 9. The two second gears 16 mesh with each other.

[0018] After the wastewater from the oil depot is pumped into the main body 1 by external pumps, the wastewater is allowed to cover several crushing rollers 10 before the injection of wastewater is stopped. Then, a flocculant (such as alum) is added, and the servo motor 12 is started. The output shaft of the servo motor 12 drives the rotating shaft 9 to rotate, which in turn causes the crushing rollers 10 to rotate, making the flocculant and wastewater from the oil depot mix more evenly. During the rotation of the rotating shaft 9, the connecting rod 14 is driven to rotate through two first gears 15, and the connecting rod 14 is driven to rotate through two second gears 16. The rotating shaft 9 drives the rotating blades 11 to rotate, causing particulate matter in the wastewater from the oil depot to settle inside the shell 3, while the oil layer in the wastewater floats on top. This reduces the amount of oil in the wastewater flowing out of the drain pipe 4, thereby reducing the degree of water pollution, reducing the burden on subsequent treatment processes, and lowering energy costs.

[0019] Example 2: An optimization based on Example 1, with reference to... Figure 1-4 One end of the rotating rod 8 is connected to the second support frame 7 via a bearing. The outer sides of the two first gears 15 and the two second gears 16 are all coated with corrosion-resistant coatings. The bottom of the housing 3 is set in an inclined shape.

[0020] The corrosion-resistant coatings on the outer sides of the two first gears 15 and the two second gears 16 are formed by nitriding, thereby improving the mechanical properties of the two first gears 15 and the two second gears 16 and increasing their service life.

[0021] Combined with appendix Figure 1-4The bottom of the shell 3 and the bottom of the main body 1 are both inclined, which makes it easier for the particles in the main body 1 and the shell 3 to settle and be discharged from the drain pipe 4.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
