Operation principle in conjunction with Fig. 1, table 1 pair the utility model evaporation type pretreatment system is described in detail, and existing is example with the tetrachloro-ethylene.
The evaporation type pretreatment system of present embodiment comprises four flow processs:
(1) dosing flow process: will add the initial junction 34 that explosive barrel (figure does not show) inserts Drainage pipe 34a and input duct 34b, correspondence table 1 is adjusted valve state.Open the 3rd water pump 33, valve b, d and e open, and tetrachloro-ethylene is heated cylinder 11 by the 3rd water pump 33 along input duct 34a suction from adding explosive barrel.
(2) normal workflow: adjust each valve, make its state corresponding to one hurdle of operate as normal in the table 1.Open first water pump 31.
Heat-generating pipe 12 begins the tetrachloro-ethylenes in the heating cylinder 11 are heated, and when reaching 122 ℃, the tetrachloro-ethylenes in the heating cylinder 11 become steam, through valve A along workflow to, enter purge chamber 20 as 1 direction of arrow A among the figure, workpiece 24 is cleaned.Workpiece 24 contacts with the tetrachloro-ethylene of gaseous state in purge chamber 20, the high-temperature gas tetrachloro-ethylene is met cold on workpiece 24 surfaces, be converted into liquid state by gaseous state, the greasy dirt stain on high-temperature liquid state tetrachloro-ethylene parcel workpiece 24 surfaces, under the effect of gravity, fall into 20 bottoms, purge chamber together.And the tetrachloro-ethylene steam of dissipation rises to workpiece transport establishment 23 tops, contacts with condenser pipe 44 to meet the cold liquid state that is converted into, thereby also falls into 20 bottoms, purge chamber.Cleaned workpiece 24 is then sent purge chamber 20 by workpiece transport establishment 23, the air blast 43 of the purge chamber outlet raffinate on the workpiece 24 that blows off.The soiling solution that enters 20 bottoms, purge chamber flows into collection cylinder 30 by leakage fluid dram 21 through filter 22.Liquid in the collection cylinder 30 flows into a separator 41 through first water pump 31, after a separator 41 separates, the part that density is big flows into heating cylinder 11 through the first outlet 41b, in heating cylinder 11, become steam again after the heating and enter the clean cycle flow process, and density little flow into No. two separators 42 by the second outlet 41c through the inlet 42a of No. two separators 42, after the liquid that enters No. two separators 42 is separated by No. two separators 42, what density was big enters collection cylinder 30 by outlet 42b, and what density was little is discharged by drain outlet 42c.
(3) shut down flow process: when all workpiece cleaning finish, need close whole system, close heat-generating pipe 12, adjust each valve, make and shut down a hurdle in its state correspondence table 1, close first water pump 31, the 3rd water pump 33 simultaneously.
At this moment; the tetrachloro-ethylene steam that the heating back produces in heating cylinder 11 flows to along shutting down through valve A; direction flows into condenser shown in arrow A 2; the tetrachloro-ethylene condensation becomes liquid state; drain into separator 16 No. three; after No. three separators 16 separated, water flowed into purge chamber 20 by the first outlet 16b, and liquid tetrachloro-ethylene flows into heating cylinder 11 by the second outlet 16c and the 3rd outlet 16d through valve e and enters recycling.
(4) cleaning process: with the initial junction 34 of receptacle (figure does not show) access Drainage pipe 34a and input duct 34b, adjust each valve, make and clean a hurdle in its state correspondence table 1, open first water pump 31 and the 3rd water pump 33 simultaneously.
Liquid in the purge chamber 20 flows into collection cylinder 30 through the residual liquid that leakage fluid dram 21 flows in 30, No. two separators 42 of collection cylinder by outlet 42d.First water pump 31 is evacuated to separator 41 No. one with liquid in the collection cylinder 30, the 3rd outlet 41d by a separator 41 enters receptacle along Drainage pipe 34b through valve c, the 3rd water pump 33 and valve a, and No. three separators 16 and the liquid that heats in the cylinder 11 also enter receptacle along Drainage pipe 34b.
In the present embodiment, also be provided with a floating ripple pumping equipment in the collection cylinder 30 of described evaporation type pretreatment system, described floating ripple pumping equipment comprises second water pump 32, and described second water pump 32 links to each other with described purge chamber 20 by pipeline.When the liquid in the collection cylinder 30 reach a certain height, will produce floating ripple signal, second water pump 32 is opened after receiving floating ripple signal, and partially liq is entered purge chamber 20, avoids the liquid in the collection cylinder 30 to overflow.
Because evaporation type pretreatment system of the present utility model adopts the high-temperature gas tetrachloro-ethylene that workpiece is cleaned, fully contact with surface of the work, and better dissolve its surperficial greasy dirt stain, dirt-removing power is strong, and the soiling solution after cleaning is isolated clean tetrachloro-ethylene after separator separates, it is recycling that it is entered, and provides cost savings.
Cleaning agent that the utility model uses is not limited to tetrachloro-ethylene, and any suitable cleaning agent all belongs to protection domain of the present utility model.The connection of the principle of the above workpiece transport establishment and each pipeline, valve is well known to those of ordinary skill in the art, no longer is described in detail at this.
Abovely the utility model is described, but the utility model is not limited to the embodiment of above announcement, and should contains various modification, equivalent combinations of carrying out according to essence of the present utility model in conjunction with most preferred embodiment.
