Embodiment 5
Transport oily suction type die heater, referring to Fig. 4, Fig. 8 and Figure 11, on the architecture basics of embodiment 3 or 4, increase a repairing groove 191, repairing groove 191 and heating tank 2 communicate through pipeline.
When using large mold; Because of the more volume in mould water route is big, need more hot coal oil to keep the running of whole water route, so append a repairing groove in die heater inside in this situation; The storage space of volume that the water route takies when replenishing operation and the hot coal oil that refluxes in the mould water route when out of service; And be merely mould water route hot coal oil in service and heat, the hot coal oil in the repairing groove does not heat, and can save energy resource consumption.
Embodiment 6
Referring to Figure 12 and Figure 13, in the above-described embodiments, described negative pressure generator 1 comprises generator shunting integrated package 111 and generator negative pressure cabin integrated package 15; Pipeline D54 inserts the high pressure access port 12 of the pump 9 of generator shunting integrated package 111; Be provided with high pressure nozzle 16 between generator shunting integrated package 111 and the generator negative pressure cabin integrated package 15, conductive medium is sprayed with high flow rate through high pressure nozzle 16 and is got into generator negative pressure cabin integrated package 15 and form negative pressure region, and high pressure nozzle 16 peripheral spaces form negative pressure cabin 17; Negative pressure cabin 17 1 ends are connected with collecting pipe 19; Collecting pipe 19 is communicated with pipeline C53, and negative pressure cabin 17 connects negative pressure cabin interface 18, and negative pressure cabin interface 18 is connected with pipeline E55; Conductive medium is 17 junctions in the negative pressure cabin, and flow back into heating tank 2 through collecting pipe 19.Described high pressure nozzle 16 is set to eight, and the quantity of the quantity of collecting pipe 19 and high pressure nozzle 16 also is eight.With the inflow direction of conductive medium to flowing out direction, the area of section of the hollow cavity that the conducted inside media of high pressure nozzle 16 flows from big to little.Form negative pressure more easily.
The conductive medium liquid in each pipeline (water or kerosene) can adopt corresponding collocation high pressure nozzle 16 of each pipeline and collecting pipe 19 in the mould in identical flow velocity and negative-pressure sucking current downflow in the mould 11 in order to reach.The pump discharge opening is distributed to each high pressure access port 12 through generator shunting integrated package 11 with water jets under high pressure, makes each pipeline of mould obtain identical negative-pressure sucking and flowing velocity, can guarantee that each position temperature of mould reaches even branch.
Negative pressure generator adopts the integrated package design to save installing space, saves a large amount of piping engineerings and pipeline parts.Combine the whole big integrated package of back directly to be affixed on the heating end plate 21 of heating tank whole negative pressure generator; The conductive medium outflow end of negative pressure generator directly is communicated with heating tank inside, directly the negative pressure generator conductive medium (water or hot coal oil) that refluxes is directly discharged back heating tank.
The conductive medium outflow end that can certainly be employed in negative pressure generator 1 is connected with pipeline C53, pipeline C53 communicates with heating tank 2, and conductive medium flows back to heating tank 2 through pipeline C53.
In the above-described embodiments, pump transfers discharge opening high-pressure injection liquid column to by heating tank suction conductive medium and directly gets back to heating tank through negative pressure generator, and middle except negative pressure generator produces resistance, having no to influence pump operating load variable again; No matter whether liquid flow is arranged and suck the unlatching of air and connecting line or close in each negative pressure cabin of negative pressure generator; Can not cause the change of pump operating load fully; Long-time again running can ensure that the pump load all maintains the design specification scope, guarantees ability and life-span that this suction type die heater turns round for a long time.
In part embodiment, surpass 120 ℃ even surpass under 350 ℃ of situation in serviceability temperature, heat exchanger is installed in the airtight heat exchange groove, be immersed in the heat exchange groove recirculated cooling water; When carrying out temperature-fall period hot coal oil when flowing through over-heat-exchanger, heat is directly taken away by the ring cooling water.Heat exchange groove recirculated cooling water flows, and can not cause a large amount of vaporization phenomenons to recirculated cooling water so elevated temperature heat kerosene flows at heat exchanger, can not damage consequence to recirculated cooling water pipeline and water pump.
A special air intake valve is installed on mould pipeline B; Take apart a die make pipeline and separate before; Open air intake valve earlier; Let air get in the airtight pipeline of mould, make to exist the working fluid interior (water or hot coal oil) to be back in the heating tank, when dismantling tube connector, exist the working fluid (water or hot coal are oily) in the pipeline just can not pollute operating environment with pipeline in order to destroy the siphonage in the pipeline.
According to technical scheme of the present invention; Before starting running; Only need to accomplish the connecting line action according to working specification; All die heaters of entry into service are outside all to be operated under negative pressure with mould tube connecting pipe road, even if pipeline has the seepage holes, the working fluid in pipeline (water or hot coal oil) does not have fully to leak to pollute or form to spray out and causes personnel's third-degree burn and contaminated environment.And guarantee that pump is under the constant load condition fully and turn round, can reach and not rest down the long-time continuous motion requirement whole year.
Certainly on heating tank 2, also be provided with temperature sensor 29 and fluid level measuring instrument 7.Fluid level measuring instrument 7 adopts high, normal, basic three accurate water level detectings.One, when the liquid-level switch detecting is the low water level signal, opens the magnetic valve that connects recirculated cooling water high-pressure side serial connection and begin when liquid-level switch is detected to middle water level, to close magnetic valve and stop moisturizing to adding the hot water storgae moisturizing; Two, when temperature surpasses setting range, the magnetic valve of opening serial connection again is to adding the hot water storgae moisturizing, makes the trough inner water temperature be reduced to the design temperature scope and closes magnetic valve and stop moisturizing; Three, simultaneously as the too big and liquid-level switch detecting of inflow when being the high water level signal at this; Begin then that unnecessary water is discharged in the cooling water return low-pressure end pipeline with adding hot water storgae; When liquid-level switch is detected to middle water level, close magnetic valve and stop draining, be used for quick control temperature and water level.
In a word, the above is merely preferred embodiment of the present invention, and all equalizations of doing according to claim of the present invention change and modify, and all should belong to the covering scope of patent of the present invention.
