Embodiment 1

[0031] Embodiment 1 of the present invention: as figure 1 As shown, a butane propulsion method used in the production of pearl cotton uses compressed air to drive a pneumatic reciprocating piston pump, and the pneumatic reciprocating piston pump extracts the butane in the butane cylinder and transports it to the buffer tank. After the butane is pressurized again, it is injected into the pearl cotton foaming equipment to participate in foaming, which specifically includes the following steps:

[0032] Step a: The compressed air generated by the air compressor is delivered to the first-stage pneumatic reciprocating piston pump and the second-stage pneumatic reciprocating piston pump respectively through the air connection pipeline;

[0033] Step b: The butane in the butane steel cylinder is sucked out by the suction generated by the first-stage pneumatic reciprocating piston pump and delivered to the buffer tank;

[0034] Step c: The butane in the buffer tank is pressu...

[0039] Embodiment 2 of the present invention: as figure 1 As shown, a butane propulsion method used in the production of pearl cotton uses compressed air to drive a pneumatic reciprocating piston pump, and the pneumatic reciprocating piston pump extracts the butane in the butane cylinder and transports it to the buffer tank. After the butane is pressurized again, it is injected into the pearl cotton foaming equipment to participate in foaming, which specifically includes the following steps:

[0040] Step a: The compressed air generated by the air compressor is delivered to the first-stage pneumatic reciprocating piston pump and the second-stage pneumatic reciprocating piston pump respectively through the air connection pipeline;

[0041] Step b: The butane in the butane steel cylinder is sucked out by the suction generated by the first-stage pneumatic reciprocating piston pump and delivered to the buffer tank;

[0042] Step c: The butane in the buffer tank is pressu...

Embodiment 3

[0047] Embodiment 3 of the present invention: as figure 1 As shown, a butane propulsion method used in the production of pearl cotton uses compressed air to drive a pneumatic reciprocating piston pump, and the pneumatic reciprocating piston pump extracts the butane in the butane cylinder and transports it to the buffer tank. After the butane is pressurized again, it is injected into the pearl cotton foaming equipment to participate in foaming, which specifically includes the following steps:

[0048] Step a: The compressed air generated by the air compressor is delivered to the first-stage pneumatic reciprocating piston pump and the second-stage pneumatic reciprocating piston pump respectively through the air connection pipeline;

[0049] Step b: The butane in the butane steel cylinder is sucked out by the suction generated by the first-stage pneumatic reciprocating piston pump and delivered to the buffer tank;

Abstract

The invention discloses a butane-pushing method and system in pearl wool production. Compressed airs are used for driving a pneumatic reciprocating piston pump; and the pneumatic reciprocating piston pump is used for extracting the butane in a butane steel cylinder and delivering the butane to the interior of a buffer tank, and the butane in the buffer tank is compressed again and then injected into a pearl wool foaming device for foaming. The system provided by the invention has the advantages of being high in safety factor, complying with the relative regulations on using the gas cylinder in China, realizing continuous air supply, and being simple in installation and maintenance and good in economic performance.

Description

technical field [0001] The invention relates to a butane propulsion method and system, in particular to a butane propulsion method and system used in pearl cotton production. Background technique [0002] In the traditional EPE production process, the propulsion of butane mainly adopts the nitrogen pressurized propulsion method, that is, the N2 in the nitrogen cylinder of 13Mpa-15Mpa is reduced to 1.2Mpa-1.4MPa by the pressure reducing valve, and then passes through the butane cylinders in series, Push the butane in the latter butane cylinder to the previous butane cylinder in turn, and finally inject it into the high-pressure metering pump. The butane is sent into the foaming machine by high-pressure metering pump to pressurize again for foaming. This butane propulsion method has the following disadvantages: [0003] Poor safety: Once the operation is wrong or the nitrogen pressure reducing valve is damaged, the high-pressure nitrogen will directly enter the butane gas cy...
