Description

Technical Field

[0001] This utility model relates to the field of oil leakage collection in launcher and receiver cylinders, and particularly to an oil leakage collection device for launcher and receiver cylinders used in oil and gas storage and transportation. Background Technology

[0002] The pig launcher and receiver in oil and gas storage and transportation is a pipeline auxiliary device used to send and receive pigs. It is mainly used for pigging and cleaning the pipeline before it is put into operation, as well as for cleaning wax, oil, and scale after it is put into operation.

[0003] When the launcher and receiver collects oil from the tubing head, impurities and oil inside the tubing will flow out. To avoid wasting oil, a collection bucket or box is usually used to collect the oil. In order to filter the impurities in the oil, a filter screen is installed on the collection bucket or box. However, the filter screen is usually fixedly installed or uses fasteners and bolts to the collection bucket. Therefore, when cleaning the impurities on the filter screen, it is necessary to disassemble and clean it. However, disassembling a fixedly installed or fastened filter screen is somewhat cumbersome, thus reducing the convenience of cleaning and maintaining the filter screen. Utility Model Content

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] This utility model provides, for example Figure 1-3 The image shows an oil leakage collection device for a launcher / receiver in oil and gas storage and transportation. Example

[0036] The assembly includes an oil collection tank 1, a ball valve 2, an oil receiving housing 3, a sealing cap 4, a filter screen 5, and an installation component 6. The ball valve 2 is installed at the inlet of the oil collection tank 1, and an oil drain port is provided at the bottom of the side of the oil collection tank 1. The oil drain port is sealed with a nut. Removing the nut allows the oil collected inside the oil collection tank 1 to be discharged. The ball valve 2 is used to control the opening and closing of the inlet on the oil collection tank 1. The oil receiving housing 3 is installed at the inlet end of the ball valve 2. The sealing cap 4 is threaded onto the top of the outer wall of the oil receiving housing 3. The filter screen 5 is installed... The oil receiving housing 3 has a filter screen 5 for filtering impurities in the oil entering the oil receiving housing 3. By removing the sealing cap 4 and opening the ball valve 2, the oil receiving housing 3 can collect the oil leaking from the receiving and launching tubes, and the filter screen 5 can filter the impurities in the oil. The mounting component 6 is located inside the oil receiving housing 3 and is used to install and bind the filter screen 5. The filter screen 5 can be removed from the oil receiving housing 3 by using the mounting component 6, so that the filter screen 5 can be cleaned directly.

[0037] In particular, the mounting assembly 6 includes an arc plate 61 and an arc groove 62. The two arc plates 61 are symmetrically fitted inside the oil receiving housing 3. The arc groove 62 is opened on the inner side of the arc plate 61. The outer wall of the filter screen 5 is slidably engaged inside the arc groove 62, so that the two arc plates 61 symmetrically wrap around the outside of the filter screen 5. The mounting assembly 6 also includes a positioning collar 64 and a positioning rod 65. The positioning collar 64 is set at the bottom of the arc plate 61. One end of the positioning rod 65 is fixedly connected to the arc plate 61. The outer wall of the positioning rod 65 is slidably inserted into the positioning collar 64, so that the positioning collar 64 binds the two arc plates 61 through multiple positioning rods 65, thereby ensuring the stability of the two arc plates 61 engaged outside the filter screen 5.

[0038] Furthermore, the mounting assembly 6 also includes a support rod 66 and a mating groove 67. The top of the support rod 66 is fixedly connected to the arc plate 61, and the bottom of the support rod 66 is in contact with the bottom of the inner wall of the oil receiving housing 3. The support rod 66 can allow the arc plate 61 to create a certain gap between the filter screen 5 and the bottom of the inner wall of the oil receiving housing 3, thereby ensuring that the filter screen 5 filters oil normally. The mating groove 67 is opened inside the positioning collar 64, and the outer wall of the support rod 66 is fitted into the inside of the mating groove 67. The mounting assembly 6 also includes a snap-fit ​​component 68 and a snap-fit ​​groove 69. The snap-fit ​​component 68 is fixedly connected to the support rod 66. On the outside of 6, the slot 69 is formed on the inner wall of the docking slot 67. The outer wall of the snap-fit ​​68 is slidably snapped into the inner cavity of the slot 69. The snap-fit ​​68 is made of elastic material. Under the action of the snap-fit ​​68, the positioning collar 64 can be stably snapped into the outside of the multiple support rods 66, thereby making the positioning collar 64 in a stable state to snap and limit the two arc plates 61. Since the snap-fit ​​68 is made of elastic material, the positioning collar 64 can also slide and separate from the snap-fit ​​68 and the support rods 66, thereby disassembling the two arc plates 61 to facilitate the disassembly and maintenance of the filter screen 5. Example

[0039] Based on Embodiment 1, the mounting assembly 6 further includes a sealing gasket 63, a connecting rod 610, and a handle 611. The sealing gasket 63 is fixedly connected to the outside of the arc plate 61, and the outer wall of the sealing gasket 63 is pressed against the inner wall of the oil receiving housing 3. The sealing gasket 63 can improve the sealing between the outer wall of the arc plate 61 and the inner wall of the oil receiving housing 3, thereby preventing oil from being discharged from the gap between the outer wall of the arc plate 61 and the inner wall of the oil receiving housing 3 without being filtered by the filter screen 5. The connecting rod 610 is fixedly connected to the arc plate 61. The top of the arc plate 61 is fixedly connected to the top of the connecting rod 610. The top of the handle 611 fits against the inner wall of the sealing cap 4. The handle 611 can be used to remove the arc plate 61 and the filter screen 5 from the inside of the oil receiving housing 3 through the connecting rod 610. When the sealing cap 4 is installed on the oil receiving housing 3, the arc plate 61 can also be locked by the handle 611 and the connecting rod 610, thereby ensuring the stability of the filter screen 5 installed inside the oil receiving housing 3 when the oil collection tank 1 is transported.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
