[Prior Art]

 FIG. 5 shows an operation system diagram of the compressor. The compressor 32 operates by the drive of the drive source 35. The air in the atmosphere enters the compressor 32 through the air cleaner 33 and the capacity regulator 34, is compressed to a predetermined pressure, and is introduced into the receiver tank 27 through the discharge pipe 38 having the check valve 39. The introduced compressed air is separated into compressed air and oil by the oil separator 1a in the receiver tank 27, and the compressed air is sent to the place of use by opening the stop valve 17 of the air supply pipe 18. The separated oil is stored in the oil reservoir 40 of the receiver tank 27. The stored oil is cooled by the heat exchanger 36 in the return oil pipe 31 and is returned to the compressor 32 for use. The pressure in the receiver tank 27 is detected by the detector 37, and a signal is sent to the capacity regulator 34 and the drive source 35 to control the air amount of the compressor and the rotation of the drive source.

The oil separator 1a in the receiver tank 27 requires regular maintenance and inspection. Insufficient periodic inspection may cause problems such as poor oil separation, poor spraying during painting work, and air tool failure. An end plate 28 is detachably attached and fixed above the receiver tank 27. The oil separator 1a is fixed to the end plate 28, and the detector 37 and various pipes 41 are detachably attached to the oil separator 1a so as to communicate with the oil separator 1a.

At the time of maintenance and inspection, the pipes 41 and the like are removed, and the end plate 28 is removed from the receiver tank 27 by removing a bolt (not shown). As described above, the oil separator 1a is taken out from the receiver tank 27 and is maintained and inspected. Upon completion of maintenance and inspection such as replacement of the oil separator element, the oil separator 1a and various pipes 41 are fixed to the mirror plate 28, and the mirror plate 28 is fixedly mounted to the receiver tank 27.

[Problems to be solved by the device]

 In order to constantly send clean compressed air to the user side, regular maintenance and inspection of the oil separator are required. To check the oil separator, the end plate and piping must be removed. However, it takes a long time for removal and installation. On the other hand, the compressor cannot be operated during maintenance and inspection of the oil separator. Therefore, prompt maintenance and inspections are required to improve productivity. However, as described above, the conventional oil separator structure has a problem that the compressor cannot be operated for a long time because the amount of work during maintenance and inspection is large and it takes a long time.

The present invention solves the above problems. The oil separator, which is conventionally disposed inside the end plate above the receiver tank, is made into a cartridge type and is disposed outside the receiver tank for maintenance and inspection work. An object of the present invention is to provide a cartridge type oil separator for a compressor, which can be simplified, handled easily, and can improve the operation rate of the compressor.

[0007]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention has a cartridge type oil separator structure detachably arranged outside a container of a receiver tank of a compressor, and has a mounting seat detachably fixed to the receiver tank. A cylindrical body connected to the mounting seat for accommodating an oil separator element; one end side fixed to the mounting seat and extending in the longitudinal direction in the oil separator element and opened at its free end side. Has a compressed air receiving pipe and an oil sump that collects the oil separated in the oil separator element. Inside the mounting seat, compressed air communication that communicates with the receiver tank side and the cylinder is established. A compressor provided with a hole, a compressed air communication path communicating with the compressed air receiving pipe, and an oil communication path communicating with the oil reservoir. It constitutes a cartridge-type oil separator structure.

[0008]

[Action]

 Compressed air of a predetermined pressure sent from the compressor to the receiver tank through the check valve enters the cylinder through the compressed air communicating hole provided in the mounting seat, and then enters the oil separator element. The compressed air is separated into compressed air and oil by the oil separator element, and the compressed air that has entered the oil separator element advances toward the opening in the upper part of the compressed air receiving pipe fixed to the mounting seat, and the oil is further separated. Separate and enter the tube through the opening. The compressed air that has entered the pipe is sent to the place of use by the air pipe through the compressed air conduit. In addition, the oil separated from the compressed air is collected in the oil sump inside the cartridge type oil separator and goes back to the low pressure part on the compressor side by the oil pipe connected to it through the oil passage formed in the mounting seat. Be done. Further, the oil in the cylinder flows into the receiver tank through the compressed air communication hole while the compressor is stopped, and is stored in the oil reservoir in the receiver tank. When replacing the cartridge type oil separator, it is sufficient to remove it directly from the end plate, and it can be easily separated from the receiver tank. By using the cartridge type oil separator in this way, maintenance and inspection work is simplified, not only maintenance work is improved, but also oil processing is simplified, and compressor operating efficiency can be improved.
