Description
Technical field
Technical field of industrial equipment is the utility model is related to, specially a kind of constant-current type enters kiln Raw Material System.
Background technology
In cement production process, accurate metering is with controlling into kiln raw material feeding capacity, to stablizing firing system thermal regulation,
Clinker and quality are improved, is played an important role.
As cement industry modernization and the development people's kiln raw material measurement technology that maximizes have caused people more and more to be closed
Note.In kiln Raw Material System is entered at present, in feed bin raw material store number, the size of aeration quantity and air-flow speed to its
Mobility influences all to be very big, and in the change of some sources of the gas, frequently occasion, measure control equipment would generally produce fluctuation, sternly
Vibration occurs during weight so that it cannot work.There are many enterprises to provide into kiln raw material metering device both at home and abroad, but neglect
Omit storehouse pressure, storehouse weight, feed bin bottom injection method etc. in kiln Raw Material System all to have a significant impact to final feed precision,
There is no integrated system to consider overall process system, it is unstable to cause finally to enter kiln Raw Material System generally existing longtime running, meter
Amount is inaccurate, gives and tracks the technical problem such as slow, is not still solved effectively at present.In addition, external feeding dress
Expensive, accessory exclusive dealing is put, delivery cycle length, maintenance and repair difficulty is big, and special spare part is more, due to technical know-how, state
Interior alternative part does not have substantially, and great restrictive function is brought to enterprise.
Manufacture of cement belongs to complicated thermal technology's course of reaction, is characterized in big inertia, hysteresis, time-varying and seriously non-thread
Property etc., and parameter is more and complicated, coupled to each other serious, system model is difficult to set up.The wherein stability pair of Raw Material System feed
Influenceed in whole thermal process very big, the changes of raw material can cause the parameter of kiln tail to kiln hood etc. everywhere, including temperature, pressure,
Oxygen content etc. changes, so as to influence the yield of cement and quality, phenomena such as also easily causing ring formation, the hot spot of rotary kiln,
Influence normal production.Traditional PID control or control manually, control effect is bad, especially when big interference occurs, control performance
Production requirement can not be met.
Enter the metering of kiln raw material and cement work of the dosing system in China using what flow control valve and flowmeter formed
Occupy significant proportion in industry, but flow measurement link (flowmeter) and Flow-rate adjustment link (flow control valve) are in physical space
Separation (by cloth wind skewed slot and be oriented to skewed slot and be coupled), the system made occurs that certain hysteresis shows in bias adjustment
As；Flow-rate adjustment valve opening and the linear relationship of uninterrupted influence the steady-state behaviour of system.Lacked so the system has two
Fall into：The charging gear one is stability that raw material give places one's entire reliance upon, flowmeter are entirely passive, and it is only to supplied materials
Measured；The second is when finding that the raw material flow by flowmeter deviates specified rate, raw material are actual to be had been moved off giving birth into kiln
Materials quantitative feed system, it is entirely to compensate afterwards at this moment to adjust charging gear, is the control system of a purely retarded.
And slug phenomenon once occurs in the pre- feed of flow control valve+closed belt formula constant feeder system, powder is fixed
It is the function of not possessing anti-slug to measure batcher, and material will be quickly through belt conveyer scale, into next stage equipment；Second, belt conveyer scale
It is not hermetically sealed measuring equipment, powder material causes environmental pollution from the junction material leakage of scale body；Third, space-consuming is big；
Fourth, in order to reduce influence of the impact of blanking point material to metering, given quantity feeding machine is typically long, apron drawing pole
Belt deviation is easily caused, maintenance workload is big.
The powder metering and dosing that this project combines the existing high stability of my company, high accuracy and high performance-price ratio fill
Put, and based on this, from system perspective, storehouse is pressed, storehouse weight, elevator electric current, feed bin bottom injection method, flow valve control
Controlling elements are made as, kiln raw material is included and integrally controls, so as to ensure that system can reach high measuring accuracy, high stability, solution
The problem of certainly entering the presence of kiln Raw Material System at present.
