Description

Small type high pressure compressor {small type high pressure compressor}

The present invention relates to a compressor, and more particularly, to a compact high-pressure compressor capable of using high-pressure air so that a user can use it more conveniently by miniaturizing the compressor.

In general, a compressor is an air generating device for inhaling, compressing, and spraying air, and is used in various places such as for vehicles, machine manufacturing, construction sites, air tools, and painting.

Compressors are largely divided into volume type and speed type. The volume type is a reciprocating type and a rotary type, and is divided into a piston type, a root type, and a screw type. The speed type can be divided into a centrifugal type and a lateral flow type.

Among them, a commonly used method is a method in which pressure is created by a screw type or a piston type and stored in a pressure tank for use. Since the screw type compresses according to rotation, there is a limit to using it mainly when using a small amount of air, and the piston type uses a larger amount of air than the screw type because it depends on the compression action through the reciprocating motion of the piston, but the mechanical efficiency and Vibration problem occurs, so it is not suitable for a place where there is a lot of usage.

Although the air generating device for using the stored air is different for each product, the air compressor 100 sucks in air to produce compressed air and the compression tank 200 stores the compressed air until the air is sucked in and used. , It is largely composed of an air cooler 300 for cooling compressed air, an air dryer 400 for drying to supply cooled air, and an air filter 500 for removing foreign substances and oil from the air.

In addition, high-pressure compressors are mainly used for industrial or industrial purposes, but recently, there are also small compressors that can be used at home. However, it is difficult to use high pressure in the work of small and medium-sized factories due to the problem of occupying space for using high pressure, and in the case of small factories, there is a problem of insufficient pressure required for the work to be performed in a small and medium-sized workplace environment.

It is intended to provide a compressor, and Korean Utility Model Publication No. 20-1996-0023401 “Air compressor that supplies various pressures” varies the pressure of compressed air used in the service line of the compressor and simultaneously supplies compressed air at different pressures. Disclosed is an air compressor that supplies various pressures so that it can flexibly cope with the required pneumatic mechanism.

A general compressor uses a screw type or piston type to create pressure, store it in a pressure tank, and then use it while maintaining a constant pressure. As shown in FIG. After creating pressure in the screw method through the primary low-pressure compressor 110, the generated pressure is stored in the primary low-pressure tank 120, and then the piston-type secondary high-pressure compressor 130 uses the pressure to use the piston method. This is a method in which pressure is generated, and the pressure is stored in the secondary high-pressure tank 140, which is a larger pressure tank, and then used.

With this method of generating pressure twice, the size can be miniaturized, but the pressure generated using the primary and secondary compressors can maintain high pressure, enabling high pressure.

At this time, the primary low pressure tank 120 may include a pressure sensor for maintaining a constant pressure.

The pressure stored in the primary low-pressure tank 120 is used to generate high-pressure pressure in a piston-type secondary high-pressure compressor 130 again. At this time, the capacity of the piston-type secondary high-pressure compressor 130 may be composed of 3 to 5 MPa.

Preferably the pressure generated secondarily is between 3.8 and 4.2 MPa.

The high pressure generated by the piston-type secondary high-pressure compressor 130 may be stored in the secondary high-pressure tank 140 and then used.

Hereinafter, each configuration for the entire process of the air flow will be described.

<Example 1>

1. 1st low pressure compression step (S1)

After air is sucked through the screw-type primary low-pressure compressor 110, a pressure of 0.5 to 0.9 MPa is created in a screw-type manner. Preferably, the primarily generated pressure is between 0.6 and 0.8 MPa.

2. Oil filtering step (S2)

The oil filter (1) serves to filter oil mixed in the air in the screw-type low-pressure compressor (110), since oil is included when the screw-type pressurization method is used in the screw-type primary low-pressure compressor (110). .

3. Cooling step (S3)

After separating only the air by the oil filter 1, the air is cooled by the cooler 3 driven by the cooler motor 2. As one of the characteristics of the present invention, for miniaturization, it is necessary to lower the temperature and minimize the volume of the air of high pressure by the compressor to store it. Therefore, the temperature of the air primarily pressured by the screw-type primary low-pressure compressor 110 is lowered through the cooler 3.

4. 1st low-pressure air storage step (S4)

The air compressed to a low pressure is stored in the primary low pressure tank 120 and then the pressure is increased again in the piston type secondary high pressure compressor 130 . At this time, the primary low pressure tank 120 may include a pressure sensor for maintaining a constant pressure.

5. Second high-pressure compression step (S5)

The pressure stored in the primary low-pressure tank 120 is used to generate high-pressure pressure in a piston-type secondary high-pressure compressor 130 again. At this time, the pressure secondarily generated by the piston-type secondary high-pressure compressor 130 is 3 to 5 MPa. Preferably the pressure generated secondarily is between 3.8 and 4.2 MPa. Since the secondary high-pressure compressor 130 is a piston type rather than a screw type, oil is not included, so a separate oil filter 1 is not required. The number of exhaust pipes of the piston-type secondary high-pressure compressor 130 may be 1 to 5. In this embodiment, it is composed of three exhaust pipes.

6. Cooling step (S6)

above 2nd In order to store the air generated by the high-pressure compressor 130 in the secondary high-pressure tank 140, it is necessary to lower the temperature and minimize the volume of the air at a high pressure by the compressor. Therefore, the temperature of the air primarily pressured by the screw-type primary low-pressure compressor 110 is lowered through the cooler 3.

7. Second high-pressure air storage step (S7)

After being generated in the piston-type secondary high-pressure compressor 130, the air whose temperature is lowered through the cooler 3 can be stored in the secondary high-pressure tank 140 and then released to be used.

At this time, the secondary high-pressure tank 140 may include a pressure sensor for maintaining a constant pressure.

8. Drying step (S8)

As a drying step for drying the air before using the air stored in the secondary high-pressure tank 140, a dehumidifier 4 is included. The dehumidification method of the dehumidifier 4 is not particularly limited.

Hereinafter, a portion of the piston type compressor belt 6 will be described in detail with reference to FIG. 3 .

The piston-type compressor motor 5 and the piston-type secondary high-pressure compressor 130 use a piston They are connected and driven by a type compressor belt (6), and the piston type compressor belt (6) is included inside the belt case (7).

To drive the piston-type secondary high-pressure compressor 130, the piston-type compressor motor 5 is driven. The driving force generated by the piston-type compressor motor 5 drives the piston-type secondary high-pressure compressor 130 through the piston-type compressor belt 6. That is, one side of the piston-type compressor belt 6 is connected to the piston-type secondary high-pressure compressor 130, and the other side is connected to the piston-type compressor motor 5. Therefore, when the piston-type compressor motor 5 rotates, the piston-type compressor belt 6 connected to the motor 5 rotates to drive the piston-type secondary high-pressure compressor 130 . At this time, it is preferable to include the piston type compressor belt 6, the rotation shaft of the piston type compressor motor 5, and the rotation shaft of the piston type secondary high-pressure compressor 130 separately in the belt case 7 so as to be used more stably. do.

In addition, it includes a controller 8 that controls the above components.
