Description

Technical Field

[0001] This invention relates to the technical field of supporting equipment for dry-type thin oil sealed gas holders, and in particular to an oil drift prevention device for dry-type thin oil sealed gas holders. Background Technology

[0002] In a dry-type thin-oil sealed gas holder, the piston rises under the pressure of the inlet pipe during gas intake. During gas supply, the piston, by its own weight, propels the gas to the user through the pipeline. The piston floats up and down between the gas holder's side plates, relying on the continuous downward flow of sealing oil to form an oil film for sealing. The sealing oil flows into the oil trough at the bottom of the holder. As the oil level in the trough rises, a float relay activates the oil pump, sending the sealing oil to the upper storage tank of the gas holder. From there, the oil flows through the overflow hole of the storage tank along the inner side of the gas holder's side plate into the piston oil trough. In this way, the sealing oil circulates repeatedly between the piston oil trough and the bottom oil trough, allowing the gas holder piston to move up and down without leakage, thus achieving a sealing effect and indirectly providing lubrication between the piston and the gas holder's side plates.

[0003] However, as the sealing oil flows from the upper oil tank along the side plate of the gas holder to the piston oil groove, it cannot completely flow into the piston oil groove when the piston is more than 45 meters away from the overflow port. Some oil droplets splash onto the piston, reducing the amount of circulating sealing oil and polluting the piston environment. To recover the splashed sealing oil, both domestically and internationally, oil collection plates are commonly installed at corresponding positions on the piston. However, in actual operation, the oil collection effect is not ideal. Summary of the Invention

[0004] To address the aforementioned problems, the present invention aims to provide a dry-type thin oil sealed gas holder anti-oil-splashing device, which can effectively solve problems such as oil splashing by using a cloth curtain to block the flow.

[0005] The technical solution adopted in this invention is as follows:

[0006] The present invention proposes a dry-type thin oil sealed gas holder anti-oil drift device, comprising a curtain, guide ropes, counterweights, pulleys, and suspension ropes; the guide ropes are respectively arranged on both sides of the middle of the top of the gas holder piston, and the lower ends of the guide ropes are connected to the piston; the pulleys are respectively installed on both sides of the middle of the lower end of the gas holder maintenance corridor via suspension ropes and correspond to the positions of the guide ropes; the upper ends of the two guide ropes are respectively connected to the counterweights after passing around the two pulleys; the curtains are respectively connected between the middle and lower regions of the two guide ropes.

[0007] Furthermore, the length of the cloth curtain is half the piston stroke of the gas holder, and the width of the cloth curtain is 200-300mm larger than the width of the sealing oil overflow port.

[0008] Furthermore, the weight of the counterweight is greater than half the weight of the guide rope plus the weight of the curtain.

[0009] Furthermore, both the counterweight and the pulley are made of Q235 ordinary carbon structural steel.

[0010] Furthermore, both the guide rope and the hoisting rope are made of φ8 steel wire rope.

[0011] Furthermore, the curtain is made of PVC Oxford cloth.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] This invention utilizes the movement of the gas holder piston to drag the cloth curtain up and down, thereby achieving the effect of blocking splashing sealing oil. Moreover, the device has a simple structure, is easy to operate, and saves time and effort. Attached Figure Description

[0017] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0018] It should be noted that in the description of this invention, the terms "upper", "lower", "top", "bottom", "one side", "the other side", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not mean that the device or element must have a specific orientation, or be constructed and operated in a specific orientation.

[0019] See appendix Figure 1-2 The present invention provides a specific structure of an embodiment of the anti-oil drift device for a dry-type thin oil sealed gas holder. The anti-oil drift device 3 includes a cloth curtain 31, a guide rope 32, a counterweight 33, a pulley 34, and a suspension rope 35.

[0020] In this embodiment, two guide ropes 32 are provided, which are respectively arranged between the top of the gas holder piston 13 and the middle of the bottom of the gas holder maintenance corridor 12, and the lower end of the guide rope 32 is connected to the top of the piston 13; two pulleys 34 are provided, which are respectively installed on both sides of the middle of the lower end of the gas holder maintenance corridor 12 by a suspension rope 35 and correspond to the position of the guide ropes 32; the upper ends of the two guide ropes 32 are respectively connected to the counterweights 33 after passing around the two pulleys 34; the curtain 31 is connected between the middle and lower part of the two guide ropes 32 and the top of the piston 13.

[0021] The weight of the counterweight 33 is greater than half the weight of the guide rope 32 plus the weight of the curtain. Both the counterweight 33 and the pulley 34 are made of Q235 ordinary carbon structural steel. Both the guide rope 32 and the suspension rope 35 are made of φ8 steel wire rope.

[0022] The length of the curtain 31 is half the stroke of the gas holder piston 13, and the width of the curtain 31 is 200-300mm larger than the width of the sealing oil overflow port 24. The curtain 31 is made of PVC Oxford cloth.

[0023] The working principle of this invention is as follows:

[0024] When gas 15 enters the gas holder 1 through the inlet pipe 17, the piston 13 rises under the pressure of the gas 15. During gas supply, the piston 13, relying on its own weight, propels the gas 15 to the user through the pipe 17. The piston 13 floats up and down between the side plates 11 of the gas holder 1, relying on the sealing oil 25 flowing downwards to form an oil film for sealing. The sealing oil 25 flows into the oil trough 16 at the bottom of the holder. As the oil level in the oil trough 16 rises, the float relay starts the oil pump station 21. The sealing oil 25 is sent to the upper storage oil tank 23 of the gas holder, and then flows into the piston oil trough 14 along the inner side of the side plate 11 through the overflow hole 24 of the storage oil tank 23. In this way, the sealing oil 25 circulates between the piston oil trough 14 and the bottom oil trough 16, allowing the piston 13 to move up and down without leakage, thus achieving a sealing effect and indirectly providing lubrication between the piston 13 and the side plate 11.

[0025] When piston 13 is at its lowest position, curtain 31 is fully extended. When gas 15 enters gas holder 1 and piston 13 rises, counterweight 33 gradually descends to the top of piston 13 under its own weight. As piston 13 continues to rise, curtain 31 descends to the top of piston 13 under its own weight, and piston 13 is at its highest position. The anti-spillage device activates in the opposite direction when piston 13 descends. By moving up and down with piston 13, curtain 31 can effectively block the sealing oil splashing from overflow port 24.

[0026] All matters not covered in this invention are common knowledge.

[0027] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
