Brief description of the drawings
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail, wherein:
Fig. 1 is the schematic diagram of efficient die heater of the present utility model.
Detailed description of the invention
Efficient die heater as shown in Figure 1, comprises storage tank 2, water circulating pump 3, heating water tank 4, cooler 5, some pipeline and electric-control systems for connecting.
Storage tank 2, water circulating pump 3, heating water tank 4 and outer mold pipe-line system 1 are connected by pipeline successively, and form major cycle water piping system.Be specially, the water inlet of water circulating pump 3 is connected with heating water tank 4 with storage tank 2 respectively with delivery port, the delivery port of the water inlet of storage tank 2 and heating water tank 4 is connected with water inlet with the delivery port in outer mold pipe-line system 1 respectively, also can the 4th hand-operated valve 14 and the 5th hand-operated valve 12 be set respectively at the water outlet of the water inlet of storage tank 2 and heating water tank 4, so that be connected with water inlet with the delivery port in outer mold pipe-line system 1.In the time that the recirculated water in outer mold pipe-line system 1 need to heat up, can, by starting the heater 41 in heating water tank 4, the recirculated water in heating water tank 4 be heated.For improving the heat insulation effect of heating water tank 4 and the efficiency of heating surface of raising heating water tank 4, be preferably and adopt the heating water tank 4 with insulation construction.Produce iron rust and cause major cycle water piping system to stop up for preventing that heating water tank 4 is corroded, heating water tank 4 preferably adopts stainless steel material to make.Thus, the heating water tank 4 after preferably comprises the outer and stainless steel internal layer of stainless steel, between stainless steel internal layer and stainless steel skin, is also filled with phenolic foam material.
Efficient die heater is also provided with the cooling system that can realize fast cooling simultaneously.Cooling system is connected between storage tank 2 and heating water tank 4, and in parallel with water circulating pump 3.On cooling system, be serially connected with cooler 5, the first check valve 51, the first magnetic valve 52 and the first filter 53.The first check valve 51 is for making recirculated water flow to heating water tank 4, the first magnetic valves 52 for controlling recirculated water in storage tank 2 when needed by entering into heating water tank 4 after cooler 5 heat exchanges from storage tank 2 again.The first filter 53 is preferably y-type filter.When actual use, under heated condition, the first magnetic valve 52 cuts out, and the heater 41 in heating water tank 4 starts, thereby can heat recirculated water; Under the state of cooling, the heater 41 in heating water tank 4 cuts out, and the first magnetic valve 52 is opened, and the recirculated water in storage tank 2 enters in heating water tank 4 by cooler 5 and water circulating pump 3 respectively.Part is cooled rapidly by the recirculated water of cooler 5, and again mixes and heat exchange with other recirculated waters in heating water tank 4, makes to flow to even water temperature in outer mold pipe-line system 1, constant.Cooler 5 is, by introducing external refrigeration water, recirculated water is carried out to heat exchange.External refrigeration water is generally the running water under normal temperature, but through refrigeration after and better lower than the cooling water heat exchange effect of normal temperature.On cooler 5, be connected with the cooling water branch road for cooler 5 being carried out to heat exchange, cooling water props up route external refrigeration water and supplies water and the hot water after heat exchange is arranged outward, and cooling water branch road is serially connected with respectively the second magnetic valve 81 and the second check valve 87 at water inlet and the water outlet of cooler 5.The second magnetic valve 81 enters into open circuit and the path of cooler 5 for controlling external refrigeration water, the second check valve 87 can not be poured in down a chimney into cooler 5 by the hot water after heat exchange for ensureing, to guarantee that cooler 5 can normally play a role.
Between the delivery port of the water inlet of storage tank 2 and heating water tank 4, be provided with the small-bore pipeline 9 directly connecting, so that storage tank 2, water circulating pump 3, between heating water tank 4 and small-bore pipeline 9, can realize the partial circulating of recirculated water, prevent under heated condition, heating water tank 4 is because lack of water is by dry combustion method, due to the discharge in small-bore pipeline 9 and by storage tank 2, water circulating pump 3, the flow of the major cycle water piping system that heating water tank 4 forms with outer mold pipe-line system 1 is compared, it only accounts for a less part, therefore can not cause larger impact to major cycle water piping system.
Recirculated water in major cycle water piping system all has evaporating loss in circulation, heating and cooling process, therefore need the recirculated water in major cycle water piping system to carry out moisturizing, efficient die heater is provided with moisturizing branch road, moisturizing branch road is connected external refrigeration water with the water inlet of water circulating pump 3, and on moisturizing branch road, is serially connected with the 3rd check valve 71 and the 4th magnetic valve 72.The 3rd check valve 71 is discharged major cycle water piping system for the recirculated water that prevents major cycle water piping system from moisturizing branch road, and the 4th magnetic valve 72 is in normally off, for when needed moisturizing branch road being communicated with.
