Description

Technical Field

[0001] The utility model relates to the technical field of petrochemical storage and transportation equipment, and particularly relates to an oil recovery joint for a sewage tank. Background Art

[0002] At present, due to reasons such as dehydration or tank washing of storage tanks in the storage area, a small amount of waste oil will flow into the sewage tank. After years of accumulation, there will be a large amount of dirty oil in the sewage tank that is difficult to handle. If heavy rain occurs and the sewage treatment is not timely, environmental pollution incidents may occur. Now, most of the waste oil can be directly pumped down through a diaphragm pump, but it is very easy to pump the sewage below the dirty oil and it is impossible to effectively pump the waste dirty oil on the surface of the sewage tank. Especially when there is dirty oil at the total rainwater discharge outlet, it is very difficult to pump it up and only absorbent felts can be used to absorb it again and again, and it is very difficult to quickly handle the dirty oil. Content of the Utility Model

[0003] The purpose of the utility model is to at least solve one of the technical problems existing in the prior art, and provide an oil recovery joint for a sewage tank, which can pump out most of the dirty oil in the sewage tank without pumping sewage, ensuring that there is not too much dirty oil in the sewage tank.

[0004] According to the first aspect of the utility model, there is provided an oil recovery joint for a sewage tank, including an oil collection cylinder and an oil pumping cylinder. The oil pumping cylinder is arranged in the oil collection cylinder. The oil pumping cylinder is connected to a diaphragm pump. One end of the oil collection cylinder is provided with a bottom seal. A plurality of oil suction holes are opened at one end of the oil pumping cylinder close to the bottom seal.

The oil pumping cylinder is arranged in the oil collection cylinder. The oil pumping cylinder is connected to a diaphragm pump. One end of the oil collection cylinder is provided with a bottom seal. A plurality of oil suction holes are opened at one end of the oil pumping cylinder close to the bottom seal. After connecting the oil pumping cylinder to the input end of the diaphragm pump and putting the oil collection cylinder into the sewage, the upper edge of the oil collection cylinder is located above the water surface and below the oil layer. In this way, the oil products on the water surface will flow into the oil collection cylinder and then be pumped out by the diaphragm pump through the oil pumping cylinder.

[0018] Refer to Figure 1 and Figure 2, an oil recovery connector for sewage tank includes an oil collection cylinder 10 and an oil pumping cylinder 20. The oil pumping cylinder 20 is arranged in the oil collection cylinder 10. The oil pumping cylinder 20 is connected to a diaphragm pump. One end of the oil collection cylinder 10 is provided with a bottom seal 11. A plurality of oil suction holes 21 are opened at one end of the oil pumping cylinder 20 close to the bottom seal 11.

[0019] It can be understood that after connecting the oil pumping cylinder 20 to the input end of the diaphragm pump, the oil collection cylinder 10 is placed in the sewage, so that the upper edge of the oil collection cylinder 10 is above the water surface and below the oil layer. In this way, the oil on the water surface will flow into the oil collection cylinder 10 and then be pumped out by the diaphragm pump through the oil pumping cylinder 20.

[0020] Refer to Figure 1 and Figure 2 , the outer wall of the oil pumping cylinder 20 and the inner wall of the oil collection cylinder 10 are connected by rib plates 30.

[0021] It can be understood that the oil pumping cylinder 20 and the oil collection cylinder 10 can be stably connected through the rib plates 30.

[0022] Refer to Figure 1 and Figure 2 , there are a plurality of rib plates 30, and the plurality of rib plates 30 are evenly distributed along the outer circumference of the oil pumping cylinder 20.

[0023] It should be noted that the evenly distributed plurality of rib plates 30 can disperse the force, evenly distribute the force on the oil pumping cylinder 20, and at the same time improve the structural stability of the oil pumping cylinder 20.

[0024] Refer to Figure 1 and Figure 2 , the distance between the oil suction holes 21 and the surface of the bottom seal 11 is not less than 30 millimeters.

[0025] It should be noted that when the operator makes a mistake and places the upper edge of the oil collection cylinder 10 below the water surface, the water entering the oil collection cylinder 10 is below the oil suction holes 21 and will not be pumped out.

[0026] Furthermore, in some other embodiments of the present invention, a quick-release joint is provided at one end of the oil pumping cylinder 20 away from the bottom seal 11. It can realize the quick connection with the input end of the diaphragm pump and improve the working efficiency.

[0027] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge scope of those of ordinary skill in the art.
