Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
As shown in Figure 1, in one embodiment, a kind of water cooling system, comprises insulation can 110, temperature-controlling module 120, pressure control assembly 130, flow control assembly 140, PLC150 and water inlet component 160.Water inlet component 160 comprises water inlet pipe 162 and water inlet motorized valve 164.Water inlet pipe 162 is communicated to insulation can 110, and water inlet motorized valve 164 is connected in the pipeline of water inlet pipe 162.
Temperature-controlling module 120 comprises vapour pipe 122, steam pressure regulator 124, steam motorized valve 126 and temperature monitor 128.Vapour pipe 122 is communicated to the inside of insulation can 110, steam pressure regulator 124, steam motorized valve 126 is connected in series in the pipeline of vapour pipe 122, and be electrically connected to respectively PLC150, temperature monitor 128 is installed on the inside of insulation can 110 and is electrically connected to PLC150, temperature monitor 128 detect insulation can 110 inside temperature and by temperature signal real-time transfer to PLC150, temperature in insulation can 110 is during lower than temperature preset value, PLC150 controls and opens steam motorized valve 126, steam pressure regulator 124 detects vapor pressure in vapour pipes 122 the real-time PLC150 that transfers to, PLC150 is according to the aperture of Steam pressure control steam motorized valve 126.Concrete adjustment process: detect the water level in attemperater 110 by water level detection switch, under the operating mode of appointment, PLC150 opens into 164 water inlets of water motorized valve, arrives after specified location when water level detection switch detects water level, stops into water; By temperature monitor 128, detected the deviation of water temperature and preset value, if temperature is low, PLC150 is by opening the 126 feedwater heating of steam motorized valve.Simultaneously, steam pressure regulator 124 is set, can monitor intuitively the variation of the vapor pressure in vapour pipe 122 on the one hand, on the other hand, when pressure that can be in vapour pipe 122 is excessive, increase the aperture of steam motorized valve 126, when pressure in vapour pipe 122 is too small, reduce the aperture of steam motorized valve 126, so that the vapor pressure in vapour pipe 122 keeps within the specific limits, in the work-ing life that is conducive to extension steam pipe 122, even can avoid the potential safety hazard because of the excessive generation of vapor pressure in vapour pipe 122.In attemperater, water temperature reaches after temperature preset value, and steam off motorized valve 126 stops heating.
In the present embodiment, water cooling system, also comprises drinking-water pipe water temperature detector 170.Drinking-water pipe water temperature detector 170 is connected in the pipeline of drinking-water pipe 132 and is electrically connected to PLC150.On insulation can 110, be connected with upflow tube 180, overflow variable valve 182 is installed on upflow tube 180.
The concrete analysis of the temperature of water coolant, pressure and flow control principle is as follows.
Temperature-controlling module is to utilize steam to heat water coolant, and is detected by transmitter input PLC150 by temperature detect switch, controls the switching of steam motorized valve 126 by PLC150, control quantity of steam number, finally make water coolant meet the requirements of temperature.It can reach: the temperature regulating range of controlling water coolant: room temperature～95 ℃; The error of Heating temperature is in ± 3 ℃; Hot steam is directly mixed with water, can not produce extra water coolant.Solved in existing traditional water-cooling system and do not carried out coolant controlled shortcoming, the temperature of water coolant is controlled and can be improved the setup time of the boiling cooling stages of material (both temperature of cooling water was to the time of boiling point), water temperature is higher, and setup time is shorter.Come to life cooling after, this stage material directly contacts with high-temperature water, high-temperature water is in the fierce boiling of material surface, the bubble of constantly overflowing has been taken away a large amount of heats, so the speed of cooling of material is very large.Just the speed of cooling of controlled prepared material from high temperature to water temperature region, provides sharp condition for high speed is cooling thus.
Pressure control assembly is in water system, to increase by a road with the upflow tube 180 of overflow variable valve 182, by the flow in overflow variable valve 182 controlling water kick pipes 180, meanwhile, coordinates the rotating speed of variable frequency pump 134, sets up different pressures in system.Object is to reach: the cooling pressure regulation range 2～20bar that controls water coolant.Solved the narrow defect of water system pressure regulation range in existing traditional water-cooling system.When water coolant is ejected into moment of material surface, can be heated immediately and vaporize, on material 50 surfaces, form one deck steam film.Because the heat conductivility of film is poor, it is very slow that drum is surrounded by it isolated workpiece cooling rate.Initial stage, because material 50 liberated heats are greater than the heat that medium siphons away from steam film, so film constantly thickens.The adjusting of cooling water pressure can rely on the hitting power of water to destroy steam film, thereby makes material enter boiling cooling stages, thereby realizes cooling fast.The increase of pressure regulation range has improved the ability of cooling stages destruction steam film, solves type material speed of cooling is required to high trend.
Flow control assembly is the flow control problem that solves each cooling point in traditional water system.The flow of water coolant each point by the under meter 144 that draws water, return flow meter 145, return valve 146, go out water regulating valve 147, backflow pneumavalve 148, water outlet pneumavalve 149, a plurality of spray flow meter 211 and realize closed-loop control with a plurality of spray variable valve 212.Due to the trial-production at same novel material or in producing, to guarantee cooling homogeneity, thus the required water yield difference of each cooling point in system, by increase the adjusting that corresponding measuring element and regulatory element are realized flow in each cooling point.By flow is controlled, the throughput ratio of the pipeline of same stages can reach 1:2.5, than traditional method, has improved 50%; Single-stage piping flow regulation range reaches 1:10, is 3 times of traditional method; Dynamic responding speed is 2s, than the time of traditional method few 50%.
For widening its subject range, increasing on the basis of the corresponding hardware of first three items, the input parameter of PLC is modified, to guarantee that these three parameters of pressure, flow and temperature can carry out independent adjusting in 90% scope.Thus, enrich greatly the working range of water cooling system, improved the science of technique and the cost performance of equipment.
The realization of water cooling system of the present utility model can be according to the existing different flexible configuration changes of constituent parts, and only needing that existing water system is carried out to certain innovative approach meets greatly new requirement.Less fund be can drop into, research and development and throughput just increased substantially.For example, can increase separately temperature adjusting or pressure and regulate, also can in system, singly add software, original system is optimized.
The water cooling system scope of application of the present utility model: metallic substance comprises the water cooling of the metals such as iron and steel, copper, aluminium; Material width: 200～450mm; Material thickness: 5～80mm; The maximum speed of cooling of material: 100 ℃/s; Surface cool temperature deviation: T ± 2.5%.
Being of wide application of water cooling system of the present utility model, for example: the controlled rolling and controlled cooling of hot-rolled steel sheet, the surface cleaning of cold-reduced sheet, the solution treatment of freight container tank body end socket are, the pressure of steel rolling working roll is cooling, all need water cooling link in the production technique of the production of iron and steel high-abrasive material, aluminium casting-rolling technology, secondary aluminum and copper annealing process.So the water cooling system of multivariable control extends in above-mentioned technique, research and develop and produce more novel material.
The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
