The circulation cooling device has the benefits of quickly reducing temperature of the coating chamber effectively, reducing the temperature of the oil diffusion pumps, solving the non-ideal problem on temperature reduction, and shortening the vacuuming time.
Description
Technical field
The utility model relates to a kind of vacuum plating unit, relates in particular to the cooling-cycle device system in this machine.
Background technology
As seen from Figure 1: have only and adopt refrigerant condenser 1 cooling process, a part of water coolant is 1 cooling from aqua storage tank 6 to refrigerant condenser, through feed pump 4, gets in two oil diffusion pumps of vacuum plating unit 61, to the processing of lowering the temperature of oil diffusion pump and whole film chamber.The water coolant that heated is got back in the aqua storage tank 6 once more through rising pipe; The water coolant of another part then cools off by high-pressure side and the whole coating equipment that secondary water pump 5 is got to DP refrigerator 2 and 3 pairs of refrigerant condensers 1 of CH refrigerator successively, and the water coolant after the heating flows back to aqua storage tank 6 through rising pipe.When the vacuum plating unit work of reality, only depend on the cooling of refrigerant condenser 1 not reach enough cooling requirements.The problem that exists: first, when eyeglass enters the vacuum plating unit plated film, because the oil diffusion pump temperature is very high, vacuum tightness in the plated film chamber can not be got off in very fast reduction, have a strong impact on the coating quality of eyeglass, and the instability of internal vacuum also can cause the aged deterioration of sealing elements such as the electron beam gun, ion gun of coating equipment inside; The second, the working hour of cooling-cycle device is long, and cooling performance is undesirable, and shorten the work-ing life of full cycle cooling system; The 3rd, because not the thinking of cooling-down effect, cause that vacuum tightness does not reach the explained hereafter requirement in the vacuum plating unit film chamber, the overlong time that vacuumizes has influenced throughput.
Summary of the invention
This practicality is transformed the technical issues that need to address and has been provided a kind of vacuum plating unit cooling back installation that is used to produce eyeglass, is intended to solve the above problems.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises: refrigerant condenser and the aqua storage tank on refrigerant condenser; A part water coolant from the aqua storage tank to the refrigerant condenser, cool off, described refrigerant condenser with water coolant through feed pump in two oil diffusion pumps of vacuum plating unit; The water coolant that was heated in vacuum plating unit is got back to aqua storage tank through the rising pipe of two oil diffusion pumps; Another part water coolant in the aqua storage tank is then got to DP refrigerator and CH refrigerator successively by secondary water pump the high-pressure side and the whole coating equipment of refrigerant condenser is cooled off, and the water coolant after the heating flows back to aqua storage tank through rising pipe; Also comprise: a cooling tower; Described cooling tower is connected between the rising pipe of aqua storage tank and two oil diffusion pumps.
Compared with prior art, the beneficial effects of the utility model are: effectively fast cooling is carried out in the plated film chamber, reduces the temperature of oil diffusion pump, solved the unfavorable problem of cooling-down effect, shortened vacuumize time; Simultaneously also solved the problem of plated film cavity temperature height, guaranteed that the even film layer of eyeglass is attractive in appearance glasses lens plated quality influence.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
By Fig. 2, Fig. 3 as seen: the utility model comprises: refrigerant condenser 1 and the aqua storage tank on refrigerant condenser 16; A part water coolant from aqua storage tank 6 to refrigerant condenser 1 the cooling, described refrigerant condenser 1 with water coolant through feed pump 4 in two oil diffusion pumps of vacuum plating unit 61; The water coolant that was heated in vacuum plating unit 61 is got back to aqua storage tank 6 through the rising pipe of two oil diffusion pumps; Another part water coolant in the aqua storage tank 6 then cools off by high-pressure side and the whole coating equipment that secondary water pump 5 is got to DP refrigerator 2 and 3 pairs of refrigerant condensers 1 of CH refrigerator successively, and the water coolant after the heating flows back to aqua storage tank 6 through rising pipe; Also comprise: a cooling tower 7; Described cooling tower 7 is connected between the rising pipe of aqua storage tank 6 and two oil diffusion pumps;
Described cooling tower 7 comprises: a water tray 71; An end that passes through a pipe 72 in the bottom of water tray 71 connects the rising pipe of two oil diffusion pumps, crosses a water shoot 73 in the side bypass of water tray 71 and links to each other with aqua storage tank 6; It above water tray 71 hay tank 74; It below in hay tank 74 filter cotton 75; The other end of pipe 72 passes filter cotton 75 and joins with revolving distributor 76; Above hay tank 74, also settle one and mix wind mechanism 77.
The utility model has increased cooling tower on the basis of original equipment, inserted cooling tower at the effluent pipe mouth of oil diffusion pump, and water coolant is flow back in the aqua storage tank through cooling tower again.
(bottom heater 8, oil molecule 9, air molecule 10, P represent that discharge, J represent to enter among the figure) as seen from Figure 4: open cooling water valve, make water coolant enter recurrent state; Water coolant is got in the coating equipment through water pump from the compression refrigerator.The coating equipment diffusion pump has maximum 5 jet apparatus (Jet stage), and cylindrical exterior connects with lead welding and teases steel pipe, below having heaters.Inner face has oil and sprays, and puts the lid of water coolant above inferior.Inlet is discharged by foreline (Fore line) gas in the above.
The oil that the low distillation that ejects from oil diffusion pump (Oil rotary pump) is pressed is just becoming oil vapour after the heating in 15-20 minute of pump the inside, spray upward.The gas molecule that the follow-up of injected oil molecule comes has been taken the gas of top out of together to following compression, and the gas molecule below the diffusion pump can improve, and discharges by Fore line.The gas molecule of taking is recycled pump (Backing pump) and gets rid of again.When gas molecule and vapour pressure descended altogether, oil vapour was circulated once more by the condensation of pump duct wall.The water coolant heating of duct wall enters cooling tower through inlet channel later on, water after the rotary water sprayer 76 that has a plurality of spout holes as the cruciform of Fig. 3 by the top will heat is sprayed in the cooling tower uniformly, constantly heat is dispersed in the tower in the process of the water droplet that sprays through filter cotton 75 infiltration downwards, and in the water tray 71 of final inflow below.The cooling tower top is equipped with the air of mixing after wind mechanism 77 will be heated and is extracted out from the top, and enters new freezing air from the below hot water is carried out the convection current cooling.Water coolant enters into to cool off on the compression cycle machine through rising pipe and recycles again in the water storage basin.
