[detailed description of the invention]
Below in conjunction with accompanying drawing, following further illustrating is done to the utility model:
As shown in drawings, the utility model comprises: air pressure input element 1, furnace pressure detecting element 2, water tank liquor position detecting element 3, baric systerm electric controling element 4, exhaust pressure relief element 5 and HMI display screen 6, air pressure input element 1 connects the air inlet in casting machine stove by pipeline, casting machine side or bottom are furnished with pressure sensor, pressure sensor is by connection furnace pressure detecting element 2, air pressure input element 1, furnace pressure detecting element 2, water tank liquor position detecting element 3, exhaust pressure relief element 5 is respectively by connection baric systerm electric controling element 4, baric systerm electric controling element 4 is by the button control zone on connection HMI display screen 6.
Wherein, air pressure input element 1 comprises filter and booster 7, and the outlet side of filter connects the air inlet in casting machine stove by pipeline, booster 7 is by connection baric systerm electric controling element 4; Furnace pressure detecting element 2 comprises the input of P/I converter 8, P/I converter 8 by connection pressure sensor, and the output of P/I converter 8 is by connection baric systerm electric controling element 4; Water tank liquor position detecting element 3 and comprise liquid-level floater and induction connecting rod, induction connecting rod is arranged in casting machine stove, induction connecting rod end is fixed with two spacing ball floats, and induction connecting rod is provided with sense contact, and induction connecting rod is by connection baric systerm electric controling element 4; Baric systerm electric controling element 4 is made up of PLC and analog input and output module, and the input of analog input and output module is connected with the output of P/I converter 8, and the output of analog input and output module is connected to PLC; Exhaust pressure relief element 5 comprises air bleeding valve 9 and rapid escape valve 10 at a slow speed, and rapid escape valve 10 is provided with two, and two rapid escape valves 10 are connected in parallel, and air bleeding valve 9, rapid escape valve 10 are respectively by connection analog input and output module at a slow speed; HMI display screen 6 is provided with pressure input area 11, actual pressure viewing area 12, pressure system state area 13, waters tank liquor position state area 14, stove internal gas pressure state area 15 and actual pressure curve district 16.
Air pressure autobalance operation principle of the present utility model is: by increasing pressure to the liquation liquid level in pouring furnace, thus promote the liquid level of watering groove, and makes to water the cast standard liquid level that tank liquor position is stabilized in requirement always by constantly increasing or reducing pressure.The gas of supercharging in stove can be that (liquation is that cast iron directly can use compressed air to filtered plant compressed air, liquation must use nitrogen as Stress control gas when being other easy oxidation metals such as magnesium iron), compressed air pressure is no less than 6bar, when first section pressure detection switch detects that pressure is too small, will automatically stop pouring into a mould and send warning; Compressed air imports confined space in stove after booster and solenoid control, acts on liquid level in stove; Pressure feedback in stove is changed through P/I, and the analog signals pressure of 0-1bar being converted into 4-20mA imports PLC into, thus realizes the FEEDBACK CONTROL of pressure.Watering groove level sensing is second data feedback control, and by two point form Liquid level, liquid level is mainly floated at spikes/low-points point-to-point transmission.When liquid level raises when causing overflow dangerous suddenly, safe spacing automatically triggers and opens rapid pressure relief valve, avoids overflow dangerous.
Air pressure input element 1 is made up of filter and booster, and filter ensures that input air (or nitrogen) is dry, and the instruction of booster reception control unit operates in good time and increases the pressure of output channel, and actual pressure information feed back to control unit.Furnace pressure detecting element 2 relies on the pressure sensor be connected in stove to send back pressure signal in real time, and be converted into analog input control unit by P/I conversion equipment.Water tank liquor position detecting element 3 to be made up of liquid-level floater (lead rod) and connecting rod, connecting rod end be fixed with two spacing, the lever motion of ball float can feed back the change of liquid level, and liquid level information is sent to control unit.Baric systerm electric controling element 4 is being made up of PLC and analog input, output module, collects pressure and liquid level information, and exports controlled pressure accurately by internal arithmetic.Exhaust pressure relief element 5 comprises electric control exhaust valve, and this electric control exhaust valve one has two kinds: air bleeding valve and rapid escape valve at a slow speed, and wherein, air bleeding valve is used for the fine setting of pressure at a slow speed, in process of production can frequent movement; Rapid escape valve is used for reducing fast furnace pressure and belongs to safeguard protection element, and rapid escape valve is provided with two, avoids one of them in case of emergency cannot action.The operation interface of HMI display screen 6 is used for the running status of Real-time Feedback pressure system, the pressure curve that furnace pressure maintains 2ms by the sampling period shows, groove fluid level condition is watered in display simultaneously, and if any fault and abnormal conditions, operation screen energy visual feedback is in Operation and maintenance personnel.
After system installation described in the utility model, need the different metal solution in corresponding stove to do and debug calibration first, concrete operations, for slowly increasing furnace pressure and storing pressure curve, afterwards along with the continuation of cast, need record maximum pressure point.When molten iron fills into, the change that pressure system has more liquid level reduces pressure, and the speed filled into according to molten iron generates pressure and reduces curve and store, and coordinates and uninterruptedly produces.When using the metal of different densities, above operation need be repeated and by the classification of metal by corresponding pressure profile memory in PLC.
The utility model is not by the restriction of above-mentioned embodiment; change, the modification done under other any does not deviate from Spirit Essence of the present utility model and principle, substitute, combine, simplify; all should be the substitute mode of equivalence, be included within protection domain of the present utility model.
