Description

Technical Field

[0001] This utility model relates to the field of packaging equipment technology, and to a vertical booster pump, particularly a vertical booster pump with high boosting efficiency and the ability to improve the efficiency of filling propellant into aerosol cans. Background Technology

[0002] A spray can is a pressure-resistant container, typically made of metal (such as tinplate or aluminum) or glass. Its core components include the container, valve system, contents, and propellant. The propellant is the power source for spraying the contents (aerosol). Currently, most propellants are liquefied gases with a boiling point below room temperature at atmospheric pressure and a high vapor pressure. When the valve is opened, the pressure suddenly drops, causing the propellant to vaporize rapidly. The pressure of the propellant propels the drug in the container out in a mist. Ideally, the propellant should have a vapor pressure greater than atmospheric pressure at room temperature; be non-toxic, non-allergenic, and non-irritating; be colorless, odorless, and tasteless; be stable, non-flammable and non-explosive, and not interact with the drug or container; and be inexpensive and readily available. During aerosol can production, the container needs to be filled with propellant. Since propellants are generally gaseous at atmospheric pressure, pressurization equipment is used to liquefy them before filling the container. While conventional pressurization equipment can pressurize gaseous propellants, it can only pressurize in one pass, resulting in low efficiency. This will affect the efficiency of filling the aerosol can with propellant.

[0003] Therefore, developing a booster pump with high pressurization efficiency and the ability to improve the efficiency of filling propellant into aerosol cans is of great practical significance. Utility Model Content

[0004] Due to the aforementioned deficiencies in the existing technology, this utility model provides a booster pump with high pressurization efficiency and the ability to improve the efficiency of filling propellant into aerosol cans, in order to solve the problem that existing booster equipment can only boost pressure in a single pass and has low efficiency, which will affect the efficiency of filling propellant into aerosol cans.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A vertical booster pump includes a drive cylinder and a booster cylinder;

[0007] The drive cylinder and the booster cylinder are arranged vertically.

[0008] The drive cylinder includes a drive cylinder barrel, with a drive cylinder upper cover and a drive cylinder lower cover at both ends of the drive cylinder barrel to close their openings. The drive cylinder barrel contains a drive cylinder piston. The upper and lower ends of the drive cylinder are respectively provided with air inlet I and air inlet II. The drive cylinder upper cover and drive cylinder lower cover are each provided with a reversing pin. Both reversing pins are equipped with drive cylinder air reversing valves. When the reversing pins are in operation, they will press against the drive cylinder air reversing valves, thereby activating the drive cylinder air reversing valves. At this time, the air supply direction of the drive cylinder changes to realize the reciprocating movement of the drive cylinder piston in the drive cylinder barrel. A pneumatic control valve is installed on the side of the drive cylinder. The pneumatic control valve is connected to air inlet I and air inlet II through gas pipelines.

[0009] The booster cylinder includes a booster cylinder barrel. The top of the booster cylinder barrel is connected to the lower cover of the drive cylinder. A booster cylinder piston is embedded inside the booster cylinder barrel. The booster cylinder piston is fixedly connected to the drive cylinder piston through a piston rod, and the piston rod penetrates the lower cover of the drive cylinder. The lower cover of the drive cylinder has a feed port and a discharge port on both sides that communicate with the inside of the booster cylinder barrel. The bottom of the booster cylinder barrel is equipped with a three-way connector that communicates with the inside of the booster cylinder barrel. The two ends of the three-way connector are respectively connected to the feed main pipe and the discharge main pipe. The feed main pipe is connected to the feed port through a feed bypass, and the discharge main pipe is connected to the discharge port through a discharge bypass.

[0010] The operating procedure for the above-mentioned vertical booster pump is as follows:

[0011] Compressed air is introduced into the pneumatic control valve, and the piston in the drive cylinder moves under the drive of the gas (assuming it's moving upwards). When the piston reaches the end of its stroke, it strikes the reversing pin. Under the action of the reversing pin, the drive cylinder air circuit reversing valve is triggered and switched, the drive cylinder air circuit is switched, and the driving direction of the drive cylinder piston is reversed (downwards). This achieves the reciprocating motion of the drive cylinder piston within the drive cylinder barrel. Simultaneously, the booster cylinder piston moves under the drive of the piston rod. As assumed, the booster cylinder piston first moves upwards. At this time, the booster cylinder piston will... The material gas on the upper side of the booster cylinder piston is compressed and liquefied. The liquefied material is discharged through the discharge bypass and discharge main pipe. At the same time, the upward movement of the booster cylinder piston draws the material gas into the space below the booster cylinder piston. When the drive cylinder piston reverses direction, the booster cylinder piston moves downward. At this time, the booster cylinder piston compresses the material gas in the space below the booster cylinder piston and liquefies it. The liquefied material is discharged through the discharge main pipe. At the same time, the downward movement of the booster cylinder piston draws the material gas into the space above the booster cylinder piston. This cycle is repeated to achieve the pressurization (liquefaction) of the material gas.

[0012] This utility model's vertical booster pump has a reasonable structural design. Its ingenious design allows the drive cylinder to pressurize the material gas in any direction. Compared with traditional booster equipment, it greatly improves the boosting efficiency, which can improve the efficiency of filling the aerosol can with propellant. It has good application prospects.

[0013] As a preferred technical solution:

[0014] As described above, a pressure gauge is installed on the discharge bypass of the vertical booster pump.

[0015] As described above, a vertical booster pump is provided with an upper one-way valve I and an upper one-way valve II on the feed bypass and discharge bypass pipe, respectively, to ensure the gas flow direction and facilitate the subsequent compression of the material gas.

[0016] The pressure gauge is located after the upper one-way valve II;

[0017] Both the discharge bypass pipe and the discharge bypass pipe are high-pressure hoses. The material gas enters the booster cylinder through the high-pressure hose and the upper one-way valve I, and is converted into high-pressure output by utilizing the principle of area difference.

[0018] As described above, in a vertical booster pump, the pressure gauge is installed on a three-way connector, and the other two connectors of the three-way connector are respectively connected to the upper one-way valve II and the discharge bypass pipe.

[0019] As described above, a vertical booster pump is provided with a lower one-way valve I between the feed main pipe and the three-way connector, and a lower one-way valve II between the discharge main pipe and the three-way connector to ensure the gas flow direction and facilitate subsequent compression of the material gas.

[0020] As described above, in a vertical booster pump, the bottom of the three-way connector is fitted with a base.

[0021] The above technical solution is only one feasible technical solution of this utility model. The protection scope of this utility model is not limited to this. Those skilled in the art can reasonably adjust the specific design according to actual needs.

[0022] Compared with the prior art, the above-mentioned utility model has the following advantages or beneficial effects:

Compared with traditional booster equipment, it greatly improves the boosting efficiency, which can improve the efficiency of filling the aerosol can with propellant. It has good application prospects. Attached Figure Description
