Description
Technical Field
The utility model relates to the field of machinery, in particular to an electric automatic control system for full-automatic production of a mechanized scrap steel crusher.
Background
With the continuous progress of society, the factory can replace the production operation of workers by artificial intelligence, thereby improving the productivity and reducing the occurrence of accidents of hurting people.
At present, all the steel scrap crushers on the market are self-suction type feeding type crushers, namely, the crushing mode that raw materials are conveyed by a chain plate through a professional master control room operator and are conveyed to a crushing cavity through a discharging groove and a double-pressure roller by a time control handle, and extrusion and impact are formed by rotation of a large rotor is generally called as a crushing mode.
Because the broken raw materials are the recycled waste copper rotten iron, the length, the thickness and the material quality of the broken raw materials are difficult to determine, the broken raw materials are not controlled in time manually, a large material shape is probably conveyed, the breaker is self-sucking, the broken raw materials can enter a breaking cavity at one time, the instant load of a main motor is increased, the overload tripping and the shutdown of the main motor are probably caused, and the phenomenon of machine blockage is caused. When the crusher is used for cleaning the blocked machine, workers need to enter the crusher for cleaning, accidents are easy to occur in the crusher, the crusher can be cleaned within 2-3 hours, the safety coefficient of the workers is greatly reduced, the production efficiency is greatly reduced, the blocked machine condition can be reduced by the operators only by feeding less materials and reducing the production current of a host machine due to the fear of the blocked machine in manual operation, and the production yield is reduced while the production is carried out.
When the crusher hammer is used to a certain degree, the phenomenon of no material feeding is generated, at the moment, the feeding is forced by the pressure and the deflection of the double-pressure roller, and because the reaction speed of manual operation is slow, the double-pressure roller cannot be stopped or lifted in time to release the stuffy plug of the double-pressure roller motor, the double-pressure roller motor is burnt out frequently, the stuffy plug of the double-pressure roller motor is easy to slip and burn out a motor belt, the motor belt is replaced by 5-6 times per shift at most, and the production cost is increased invisibly.
The following problems occur in the production process, which affect the production efficiency and increase the production cost, and the workers are also tired.
One, motor drive pair pressure roller
The drive motor can often generate overcurrent stuffiness and blockage, so that the motor is heated and burned out, and the speed reducer is broken.
The overcurrent of the electrical elements trips and burns out, and the V-belt is frequently replaced, thus the production cost is invisibly increased.
Two, hydraulic motor drive double pressure roller
The motor seal is damaged and oil leaks, rendering the motor stiff.
The frequent impact of high pressure oil damages the precise structure inside the motor, and only the motor assembly needs to be replaced.
The hydraulic pump is frequently suppressed to shorten the service life of the oil pump and increase the burning probability of the motor of the oil pump.
Third, the phenomenon of machine blockage due to vehicle congestion
1. The operator has slow reaction speed to the feeding, and the feeding is not accurately controlled, so the phenomenon of stuffiness is easily caused.
2. The machine is blocked frequently, so that the accident probability of workers is increased, and the effective production time is reduced.
Current instability of high-voltage motor
1. The current of the main motor cannot be well stabilized in a certain range by manual operation, and the curve characteristic of the main motor cannot be well exerted, so that the service life of the main motor is shortened, and the performance is reduced.
2. The power factor of the high-voltage power grid cannot be guaranteed, and fine money of the electric power industry department is easily caused.
Five, more production process personnel
1. Manual production requires a professional operator and is a little too long to keep on the operating floor.
2. In busy production, even two operators are required to be on duty alternately every shift, thereby increasing the production cost.
3. During production, an inspection worker needs to be arranged independently, and the production cost is directly increased.
Sixth, production efficiency
1. The method has the advantages of manual production, slow reaction speed, easy machine blockage and low productivity in unit time.
2. People have the process of eating and drinking, the periods are all in the production stop state, and the dozing and tiredness are also the aspects of reducing the productivity in unit time.
