The specific embodiment
The invention will be further described below in conjunction with specific embodiment.
This forging industry closed cooling tower cooling device, comprise closed cooling tower 11 and fuel tank 14, support 24 is fixedly arranged in closed cooling tower, at support 24 coil pipe 25 is arranged fixedly, closed cooling tower 11 in coil pipe 25 positions is provided with air-inlet grille 22, one end of coil pipe 25 has cold oil outlet 15, the other end of coil pipe 25 has hot oil inlet 16, be connected with cold oil pipe 1 between the entrance point of cold oil outlet 15 and fuel tank 14, between the port of export of fuel tank 14 and hot oil inlet 16, be connected with deep fat pipe 2, in the closed cooling tower 11 below coil pipe 25 water leg 13 is arranged fixedly, be provided with blowoff valve 19 in the bottom of water leg 13, be provided with overflow valve 17 and water compensating valve 18 at water leg 13, be provided with spray filler 20 in the closed cooling tower 11 above coil pipe 25, be provided with aproll dish 26 in the closed cooling tower 11 above spray filler 20, entrance point at aproll dish 26 is connected with shower 21, the entrance point of shower 21 is positioned at water leg 13, be provided with spray pump 23 at shower 21, be provided with blower fan 10 in the top ends of closed cooling tower 14.
Described cold oil outlet 15 is positioned at the top of hot oil inlet 16.
Be provided with liquid level gauge 9 at fuel tank 14.
Between the port of export of fuel tank 14 and hot oil inlet 16, be connected with and be provided with y-type filter 7, check-valves 6, oil pump 5, butterfly valve 4 and fine filter 3 on the deep fat pipe 2 successively.
Closed cooling tower 11 in coil pipe 25 positions offers access door 12.
In fuel tank 14, fixedly be useful on the screen pack 8 that the fluid that the port of export that is about to by fuel tank 14 is flowed out carries out primary filter.
Forging equipment work is with oil cooling but the time, in the suction closed cooling tower 11 by oil pump 5, intercepts dirt in a part of fuel tank 14 through screen pack 8; Further filter out dirt by y-type filter 7, enter in the closed cooling tower 11 by oil pump 5, fine filter 3 is housed before the closed cooling tower 11 prevents that assorted dirt from entering blocking pipe in the coil pipe 25.Check-valves 6 is housed before the oil pump 5 prevents that deep fat from refluxing.The thermal technology enters in the closed cooling tower 11 inherent coil pipes 25 as oil and from bottom to top circulates, and the heat of generation is absorbed by coil pipe 25; Outside shower water pumps in the aproll dish 26 at closed cooling tower 11 tops through spray pump 23 by shower 21, be sprayed on the coil pipe 25 after process packing 20 cools off it, the hot saturated vapor of consequent gentleness is discharged outside the towers by the blower fan 10 at closed cooling tower 11 tops.Shower water falls in the water leg 13 for recycling next time.The work that has been cooled is back in the fuel tank 14 by cold oil pipeline 1 with oil, supplies with forging equipment and uses.
