Background technology
The vibro-feeder intelligent controller is widely used in fields such as chemical industry, chemical fertilizer, cement, casting, grain processing.The controller function of the manufacturer production of domestic existing several families production vibra feeder controller is simpler, can only control delivery rate by regulating manually, and degree of automation is low, and operator's labour intensity is big.For example the post takes place in the acetylene gas in the acetylene workshop section of the PVC of vague generalization factory workshop, and vibro-feeder has just been used in the calcium carbide blanking, and past adopts manually and controls, and operating personal is regulated the calcium carbide blanking velocity according to the Acetylene Gas Holder height.And operating personal adopts some unscientific methods in order to reduce labor intensity: the blanking of hurrying up earlier, make the material in the producer more, reaction is fast, allow gas holder rise higherly, obtain the rest of certain hour, treat that then gas holder drops to the material that pushes ahead vigorously again when very low, go round and begin again, like this safety in production has been brought very big threat.Reaction in producer is along with the increase of blanking amount is tending towards fierce, and pressure can fiercely raise, and can blast when serious.For example, it is too fast that blanking once took place chemical plant, Inner Mongolia Autonomous Region, and gas has little time to discharge acetylene gas generator, and the accident of blasting.Gas holder height is too high, and the emptying phenomenon can take place, and makes the acetylene gas exhaust to atmosphere, has not only wasted resource, has also increased the danger of blast; Gas holder height is too low, also can produce gas holder and be inhaled flat danger, causes gas holder to damage and stops production, and brings about great losses.Another shortcoming of such way is: blanking is too fast, makes material reaction insufficient, has increased consumption of raw materials.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of degree of automation height is provided, and safety performance is good, can reduce labor strength, reduces the vibro-feeder intelligent controller of wastage of material.
The technical scheme that realizes above-mentioned purpose is: a kind of vibro-feeder intelligent controller; comprise cabinet; connection terminal and link together and form the electronic devices and components of control circuit by lead; control circuit is by adding the feed bin valve position sensor; the producer pressure sensor; the Acetylene Gas Holder height sensor; programmable controller; intelligent digital regulator; thyristor and over-voltage protection element; diverter; the electric and magnetic oscillation coil; pulsatory current transmitter and direct supply are formed; direct supply is the pulsatory current transmitter; the producer pressure sensor; the Acetylene Gas Holder height sensor provides electric energy; add the feed bin valve position sensor; the producer pressure sensor; the Acetylene Gas Holder height sensor is connected with the input end of programmable controller; one mouth of programmable controller is connected with the input end of intelligent digital regulator; another mouth of programmable controller is connected with thyristor and over-voltage protection element; the mouth of pulsatory current transmitter is connected with the input end of intelligent digital regulator and diverter respectively; the mouth of intelligent digital regulator is connected with the control end of thyristor and over-voltage protection element; the mouth of thyristor and over-voltage protection element is connected with the input end of diverter, and the mouth of diverter is connected with the electric and magnetic oscillation coil.
After adopting technique scheme, record gas holder height by the Acetylene Gas Holder height sensor, gas holder height is controlled at about 65%, when gas holder height reaches 85%, cuts off the electromagnetic shaker electric current automatically, pressure stops to feed in raw material, avoided " the emptying phenomenon " of the too high generation of gas holder height, not only saved resource, also avoided the danger of blast, the gas holder height held stationary has strengthened safety; Measure the pressure of acetylene gas generator by the acetylene gas generator pressure sensor, when the pressure of acetylene gas generator reaches 12KPa, make the electromagnetic shaker electric current reduce to 3A, blanking velocity slows down earlier, when acetylene gas generator pressure continues to rise to 14KPa, controller cuts off the electromagnetic shaker electric current, forces to stop to feed in raw material, and has guaranteed the safety of producing; When acetylene gas generator was reinforced, the acetylene gas generator baiting valve was opened, and forced to stop to feed in raw material.Whole process need not to control manually, has improved the degree of automation of vibro-feeder, has reduced operative employee's labour intensity, and can make material reaction abundant, has reduced consumption, has avoided the waste of raw material.
