As preferably, described water heater funnel comprises two tubular heat exchange systems and controlled thermal source variable valve.
As preferably, described heat exchange system is set to four tubular heat exchange systems.
As preferably, described hot water heating groove is provided with the back-water valve taking back water.
Compared with prior art, usefulness of the present invention is: this constant difference heating unit, adopt reaction type secondary dynamic heat technology, meet the Phosphating Solution mechanism slowing down crystallization formation under certain condition, meanwhile, be reduced to the access times and usage quantity of removing the poisonous and harmful solution that crystallization uses, thus not only achieve and delay Phosphating Solution crystallization generation time, and be conducive to environmental protection, and cost-saving, be applicable to applying.
accompanying drawing illustrates:
Below in conjunction with accompanying drawing, the present invention is further described:
Fig. 1 is front cross-sectional structural representation of the present invention
In figure: 1, hot water heating groove 2, Phosphating Solution heating tank 3, workpiece spray groove 4, control valve 5, joint control temp measuring system 51, T1 temp measuring system 52, T2 temp measuring system 53, temperature-regulating system 6, water heater funnel 61, two tubular heat exchange systems 62, controlled thermal source variable valve 7, heat exchange system 8, back-water valve
embodiment:
Describe the present invention below in conjunction with the drawings and the specific embodiments:
A kind of constant difference heating unit, comprise hot water heating groove 1, Phosphating Solution heating tank 2, workpiece spray groove 3 and multiple control valve 4, described hot water heating groove 1 and Phosphating Solution heating tank 2 are provided with and carry out integrated temperature test and the joint control temp measuring system 5 controlled to both, described joint control temp measuring system comprises the T1 temperature measurer 51 be placed in hot water heating groove 1, be placed in the T2 temperature measurer 52 in Phosphating Solution heating tank 2 and include the temperature-regulating system 53 of cascade raising temperature Δ T dynamic heat program, described hot water heating groove 1 is provided with and connects external heat source and the water heater funnel 6 automatically carrying out adjusting according to the data of temperature-regulating system 53 feedback external heat source, heat exchange system 7 is also provided with between described hot water heating groove 1 and Phosphating Solution heating tank 2, for ease of regulating the Heating temperature of water heater funnel 6 and increasing its heat cycle effect, described water heater funnel 6 comprises two tubular heat exchange systems 61 and controlled thermal source variable valve 62, for improving the efficiency of heat cycle between described hot water heating groove 1 and Phosphating Solution heating tank 2, described heat exchange system 7 is set to four tubular heat exchange systems, in addition, for strengthening recycling water utilization efficiency, described hot water heating groove is provided with the back-water valve 8 taking back water.
In specific implementation process, first heated by the water of controlled external heat source in controlled thermal source variable valve 62 to water heater funnel 6 in two tubular heat exchange systems, 61 pairs of hot water heating grooves 1, owing to being provided with T1 temperature measurer 51 and T2 temperature measurer 52 and including the temperature-regulating system 53 of cascade raising temperature Δ T dynamic heat program in hot water heating groove 1 and Phosphating Solution heating tank 2, temperature in the hot water heating groove 1 that described temperature-regulating system 53 feeds back according to T1 temperature measurer 51 and T2 temperature measurer 52 and Phosphating Solution heating tank 2 and the parameter of setting themselves and program, control the size that controlled thermal source variable valve 62 regulates thermal source amount, thus make water temperature in hot water heating groove 1 reach temperature required, and owing to being provided with four tubular heat exchange systems that can carry out heat exchange and thermal cycling to both between hot water heating groove 1 and Phosphating Solution heating tank 2, thus again the Phosphating Solution in Phosphating Solution heating tank 1 heated by four tubular type caloric values system of changing and reach temperature required, then, the temperature fed back by temperature-regulating system 53 and T1 temperature measurer 51 and T2 temperature measurer 52 again and program setting, control again and regulate the size of controlled thermal source amount, and water in hot water heating groove 1 is heated to temperature required, so, continuous circulation also makes the Phosphating Solution in described Phosphating Solution heating tank 2 be heated to target temperature also for workpiece spray groove 3, and in the process used, because Phosphating Solution temperature after spray can reduce and get back to Phosphating Solution heating tank 2, therefore can continue again to repeat above-mentioned circulating-heating process again, thus formative dynamics balance, reach normal object of producing, above-mentioned constant difference heating unit, reaction type secondary dynamic heat technology, meet the Phosphating Solution mechanism slowing down crystallization formation under certain condition, simultaneously, be reduced to the access times and usage quantity of removing the poisonous and harmful solution that crystallization uses, thus not only achieve and delay Phosphating Solution crystallization generation time, and be conducive to environmental protection, cost-saving, be applicable to applying.
It is emphasized that: be only preferred embodiment of the present invention above, not any pro forma restriction is done to the present invention, every above embodiment is done according to technical spirit of the present invention any simple modification, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
