[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. By setting a filter joint and a circulation pump, the two ends of the cooling S pipe are connected to the gyratory machine. The started circulation pump can circulate the lubricating oil in the cooling S pipe and the lubricating oil in the gyratory machine. The circulation pump transports the lubricating oil in the cooling S pipe to the gyratory machine. When the lubricating oil in the gyratory machine enters the interior of the cooling S pipe from the filter joint, the impurities generated by the operation of the gyratory machine will be filtered by the filter plate, and the flowing lubricating oil drives the blade to rotate, and then drives the scraper to rotate, wiping the surface of the filter plate to avoid the filter plate from being blocked.

At this time, the condensing S-tube 2, the compressor, the condensing S-tube 1, the expansion valve and the internal refrigerant constitute a complete heat exchange circulation system. The refrigerant is sucked in by the compressor for compression, and the compressed refrigerant quickly increases in temperature. The high-temperature and high-pressure gas is sent to the inside of the condensing S-tube 2, and the heat dissipation fan is used to dissipate heat and cool the condensing S-tube 2, and convert it into liquid, and then transported to the inside of the condensing S-tube 1 through the expansion valve. The expansion valve converts it from a liquid state to an aerosol state, and the temperature drops sharply, thereby realizing the cooling and heat absorption of the lubricating oil circulated in the cooling S-tube, and realizing the effective cooling of the lubricating oil in the gyratory machine.

[0015] 2. By inserting the card block into the card slot, the heat dissipation fan is inserted into the installation frame. At this time, the tension of the second spring is applied to the card bolt, so that the card bolt is inserted into the inside of the card hole, and the fixed installation of the heat dissipation fan is completed. When disassembling the heat dissipation fan, the card bolt is pulled manually to make the end of the card bolt detach from the inside of the card hole. At this time, the elastic force of the first spring is applied to the top plate and the card block is pushed out from the inside of the card slot, which facilitates the disassembly of the heat dissipation fan and makes it more convenient for the staff to clean the surface of the second condenser S tube.
