After operation is finished, a compressed air inflator needs to be used for inflating a respirator gas cylinder, but manual pressure relief and pollution discharge are needed after inflation reaches a certain pressure, waste gas discharged in the process contains a large amount of oil-gas mixture, indoor wall and ground pollution is caused, oil gas is flammable and explosive, and potential safety hazards exist.

Description

Technical Field

[0001] The present invention relates to the technical field of compressed air inflators, in particular to an oil and gas collector for a compressed air inflator. Background Art

[0002] When working in confined spaces, it is necessary to wear a positive-pressure air respirator, which involves refilling the cylinder with compressed air. Positive-pressure respirators are self-contained, open-circuit air respirators that protect firefighters and emergency rescue personnel from inhaling harmful toxic gases, smoke, and airborne pollutants during firefighting or emergency rescue operations. Positive-pressure respirators can also be used in oxygen-deficient environments to prevent the inhalation of toxic gases, enabling effective firefighting, emergency rescue, and labor operations. After the operation is completed, the cylinder must be inflated with a compressed air inflator. Once the air reaches a certain pressure, the machine's pressure relief valve must be manually opened to release the waste gas. This contains a large amount of oil and gas mixture, which must be manually wiped away, contaminating indoor walls and floors. Oil and gas are also flammable and explosive.

[0003] In view of the above shortcomings, an oil and gas collector is urgently needed. The collector is composed of a quick connector, a high-pressure pipe, and a high-pressure collection barrel. The bottom of the high-pressure collection barrel is paved with sponge to buffer the pressure of 30MPA and the splashing of waste oil and gas, achieving the idea of ​​environmental protection of oil and gas collection and ensuring the safety of operators. Summary of the Invention

At this time, by opening the exhaust valve, the oil and gas can be input into the collection chamber through the high-pressure pipe. Under the action of the first sponge at the bottom end, the splashing of oil and gas is reduced, and then accumulated at the bottom of the collection chamber under the action of gravity, and the excess gas is filtered by the second sponge and discharged through the output pipe, thereby achieving the idea of ​​environmental protection of oil and gas collection and ensuring the safety of operators.

[0020] Example: Figures 1 to 3 The oil and gas collector for a compressed air inflator shown includes an oil and gas collector 1 and a compressed air inflator 2. The input end of the oil and gas collector 1 is connected to the output end of the compressed air inflator 2, and the oil and gas collector 1 is used to store the oil and gas mixture discharged by the compressed air inflator 2; the top of the oil and gas collector 1 is fixedly connected to an input pipe 11, and the outer side of the input pipe 11 is threadedly sleeved with a connecting cap 13, and the top side of the oil and gas collector 1 is fixedly connected to an output pipe 12, and an observation window 14 is provided on one side of the oil and gas collector 1. A collection chamber 15 is provided inside the oil and gas collector 1, and a first sponge 16 is fixedly connected to the inner wall of the collection chamber 15. A second sponge 17 is connected between the input pipe 11 and the oil and gas collector 1, and the bottom end of the input pipe 11 is lower than the height of the second sponge 17, and the bottom end of the output pipe 12 is higher than the height of the second sponge 17.

[0021] The output end of the compressed air inflator 2 is fixedly connected to an exhaust valve 21, and the output end of the exhaust valve 21 is fixedly connected to an exhaust pipe 22. The outside of the exhaust pipe 22 is fixedly connected to a high-pressure pipe 23 via a clamp. One end of the high-pressure pipe 23 is interconnected with the input end of the oil and gas collector 1. One end of the high-pressure pipe 23 is inserted into the outside of the top of the input pipe 11, and the connecting cap 13 is threadedly sleeved on the outer wall of the input pipe 11 to further fix the high-pressure pipe 23 to the external thread 111. The outside of the input pipe 11 is provided with an external thread 111, and the inside of the connecting cap 13 is provided with an internal thread 131. The internal thread 131 is threadedly sleeved and connected to the external thread 111. The inside of the connecting cap 13 is provided with a connecting hole 132 for inserting the high-pressure pipe 23 inside. The oil and gas collector 1 has two parts, upper and lower, connected by threaded sealing, which is convenient for disassembly and cleaning or replacement of the interior.

[0022] When in use, the oil and gas collector for the compressed air inflator works as follows:

[0023] Compressed air inflation process:

[0024] The compressed air inflator 2 starts to work, generating high-pressure compressed air.

[0025] The compressed air passes through the exhaust valve 21 and enters the exhaust pipe 22 .

[0026] The exhaust pipe 22 is connected to the high-pressure pipe 23 through a clamp to ensure stable transmission of high-pressure gas.

[0027] The oil-gas mixture enters the oil-gas collector:

[0028] One end of the high-pressure pipe 23 is inserted into the outer side of the top end of the inlet pipe 11 of the oil and gas collector 1 and is further fixed by the connecting cap 13 .

[0029] The connection cap 13 is threadably connected to the external thread 111 on the outside of the input pipe 11 via the internal thread 131 on the inner side thereof, thereby ensuring the sealing between the high-pressure pipe 23 and the input pipe 11 .

[0030] High-pressure gas (containing oil) enters the input pipe 11 through the high-pressure pipe 23 and flows downward to the internal collection chamber 15 of the oil and gas collector 1 .

[0031] Oil and gas separation and collection:

[0032] When the oil-gas mixture enters the collecting chamber 15, it first encounters the second sponge 17. The second sponge 17 plays a preliminary filtering role, which can absorb part of the oil while allowing the gas to pass through.

[0033] The oil-gas mixture continues to flow downward. Since the bottom end of the input pipe 11 is lower than the height of the second sponge 17 , the heavier oil portion may be deposited at the bottom of the collection chamber 15 below the second sponge 17 .

[0034] The gas continues to rise and is further filtered by the first sponge 16. The first sponge 16 can absorb more oil, ensuring that the gas finally discharged is relatively pure.

[0035] The provision of the observation window 14 allows the user to observe the conditions inside the collection chamber 15 at any time, such as the degree of oil accumulation.

[0036] Gas output:

[0037] The filtered gas is discharged from the oil and gas collector 1 through the output pipe 12. Since the bottom end of the output pipe 12 is higher than the height of the second sponge 17, it is ensured that only the filtered gas can be discharged.

[0038] Maintenance and cleaning:

[0039] When the observation window 14 shows that the oil in the collection chamber 15 has accumulated to a certain extent, the user can stop the compressed air inflator 2 and clean the oil and gas collector.

[0040] By removing the connection cap 13 , the connection between the high-pressure tube 23 and the input tube 11 can be conveniently disconnected, and the collection chamber 15 , the first sponge 16 and the second sponge 17 can be cleaned or replaced.

[0041] In summary, the oil and gas collector for the compressed air inflator realizes the effective collection and filtration of the oil and gas mixture generated by the compressed air inflator through reasonable structural design, thereby ensuring the purity of the gas and the stable operation of the equipment.
