Description of drawings
Further specify the utility model below in conjunction with the drawings and specific embodiments.
Fig. 1 is a structural representation of the present utility model.
Among the figure, 1. fuel tank; 2. fuel tank oil-out; 3. air inlet; 4. blast pipe; 5. gas outlet; 6. oil return bucket oil-out; 7. circulating pump; 8. oil inlet pipe; 9. oil return bucket oil-in; 10. oil return bucket; 11. sewage draining exit; 12. oil return bucket oil return opening; 13. thermotank oil-in; 14. thermotank; 15. thermotank oil-out; 16. ball valve; 17. filter; 18. magnetic valve; 19. cooling water inlet; 20. coolant outlet; 21. bypass; 22. cold circulating line; 23. mould; 24. thermal cycle pipeline.
The specific embodiment
Further specify below in conjunction with accompanying drawing, and the related scope of unrestricted the utility model.
Referring to shown in Figure 1, the utility model comprises fuel tank 1, thermotank 14, cold circulating line 22 and thermal cycle pipeline 24, and workflow of the present utility model is:
1) correct connecting line, refuel in fuel tank 1 by reservoir port, oil flows to the oil return bucket oil-in 9 of below of oil return bucket 10 from the fuel tank oil-out 2 of fuel tank 1 by oil inlet pipe 8, gas enters the air inlet 3 of fuel tank 1 in the oil return bucket 10 through blast pipe 4 by gas outlet 5, discharge from the top reservoir port of fuel tank 1, the oil of oil return bucket 10 also can enter thermotank 14 through circulating pump 7 by thermotank oil-in 13 from oil return bucket oil-out 6.Fill it up with after the oil, static five minutes, begin to start temperature controlling machine.
