Abstract
Description
Technical Field
[0001] This utility model relates to the field of chemical equipment technology, specifically to a lubricating oil recovery device for leakage from bearing housing plugs. Background Technology
[0002] Currently, pumps and other moving equipment are essential in petrochemical production plants. During operation, oil leaks frequently occur due to factors such as operating time and equipment condition, especially at the bearing housing plugs, where lubricating oil leaks are prone to occur. This not only affects equipment operation but also causes environmental pollution and makes the site difficult to clean, causing inconvenience to on-site personnel. Furthermore, if oil leaks are not detected in time, the lubricating oil level will drop as the leaking oil is not replenished in time, leading to equipment damage and losses. Utility Model Content
[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a lubricating oil recovery device for leakage from the screw plug of a bearing housing.
[0004] To achieve the above objectives, the technical solution of this utility model is: a lubricating oil recovery device for leakage from thread plugs in bearing housings, comprising a threaded head, an oil collection groove provided below the thread on the threaded head, all oil collection grooves being inclined, an oil storage groove provided on the outer periphery of the threaded head, an oil collection cup provided at the lower end of the threaded head, and an inverted U-shaped siphon tube provided at the center of the bottom of the threaded head, one end of the siphon tube extending laterally outward and connecting to the oil storage chamber of the oil storage groove, and the other end of the siphon tube connecting to the oil collection cup.
[0005] Furthermore, the oil collection trough is provided with an oil guide pin at its lowest point.
[0006] Furthermore, the lower end of the threaded head is provided with a connecting inner ring, the connecting inner ring is provided with an external thread, the top center of the oil cup is provided with a connecting outer ring, the connecting outer ring is provided with an internal thread, and the oil cup is connected to the connecting inner ring through the connecting outer ring thread.
[0007] Furthermore, the top of the oil cup is provided with an exhaust hole.
[0008] Furthermore, the upper end of the oil storage tank is a cylinder, and the lower end is a hexagonal prism.
[0009] The beneficial effects of this utility model are as follows: This utility model has a simple structure and is easy to operate. It solves the environmental pollution caused by lubricating oil leakage from the bearing housing of the equipment and can promptly recover and treat the leaked lubricating oil. At the same time, it can facilitate the timely detection of lubricating oil leakage by inspection or maintenance personnel, avoid damage to bearings or equipment caused by low lubricating oil levels due to lubricating oil leakage, reduce equipment maintenance, and ensure the stable operation of the equipment.

[0010] Figure 1 This is a schematic diagram of the structure of this utility model;
[0011] Figure 2 This is a cross-sectional view of the present invention.
[0012] In the diagram: 1. Threaded head; 2. Oil reservoir; 3. Oil reservoir; 4. Vent hole; 5. Oil collection trough; 6. Oil cup; 7. Siphon tube; 8. Connecting inner ring; 9. Oil guide pin; 10. Connecting outer ring. Detailed Implementation
[0013] Example:
[0014] like Figure 1 and Figure 2 As shown, a lubricating oil recovery device for bearing housing thread plug leakage includes a threaded head 1. The threaded head 1 has an oil collection groove 5 below the thread, all oil collection grooves 5 are inclined, and an oil guide pin 9 is provided at the lowest point of each oil collection groove 5. An oil storage groove 3 is provided on the outer periphery of the threaded head 1, the upper end of the oil storage groove 3 being cylindrical and the lower end being hexagonal prism. An oil cup 6 is provided at the lower end of the threaded head 1, and an inverted U-shaped siphon 7 is provided at the center of the bottom of the threaded head 1. One end of the siphon 7 extends laterally outward and connects to the oil storage cavity 2 of the oil storage groove 3, while the other end of the siphon 7 connects to the oil cup 6.
[0015] The lower end of the threaded head 1 is provided with a connecting inner ring 8, the connecting inner ring 8 is provided with an external thread, the top center of the oil cup 6 is provided with a connecting outer ring 10, the connecting outer ring 10 is provided with an internal thread, and the oil cup 6 is threadedly connected to the connecting inner ring 8 through the connecting outer ring 10.
[0016] The top of the oil cup 6 is provided with an exhaust hole 4.
[0017] When installing the bearing housing plug, a wrench can be used in conjunction with the hexagonal prism below the oil reservoir 3 to tighten it. After installation, the equipment operates normally. When lubricating oil leaks, the leaked lubricating oil will leak into the oil collection tank 5 along with the bolts. Because the oil collection tank 5 is inclined, the lubricating oil will flow to the lowest point of its inclination and converge, and flow into the oil storage chamber 2 of the oil reservoir 3 through the oil guide pin 9 in the form of oil droplets or a stream. As the stored liquid level rises, when the liquid level exceeds the highest point of the siphon pipe 7, a siphon will be formed. Under the siphon principle, the lubricating oil in the oil reservoir 3 will be sucked into the oil collection cup 6. The oil collection cup 6 is made of transparent material. When the inspection personnel find lubricating oil in the oil collection cup 6 during inspection, it proves that the oil leak at the plug is serious. The maintenance personnel should be contacted in time for repair. Therefore, the leaked lubricating oil is prevented from directly leaking onto the equipment base or into the atmosphere, causing environmental pollution. At the same time, it is easy for the inspection personnel to observe and detect, reducing the damage to the equipment caused by excessive undetected lubricating oil leakage.
[0018] The oil cup 6 can be unscrewed from the connecting outer ring 10, the collected lubricating oil can be poured into the waste oil drum, and then screwed back on for reuse. Then, a leak-proof gasket can be added to the threaded head 1 at the leak point and tightened for use.
[0019] The embodiments described above are merely preferred solutions of this utility model and are not intended to limit this utility model in any way. Other variations and modifications are possible without departing from the technical solutions described in the claims.
[0020] In the description of this utility model, it should be understood that the terms indicating orientation or positional relationship are based on the orientation or positional relationship shown in the drawings and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
