Description

An automatic discharging system and control method for a finished product silo of a factory mixing equipment

technical field

The invention relates to the field of construction engineering, in particular to an automatic discharging system and a control method for a finished product silo of a factory mixing equipment.

Background technique

The current field mixing equipment finished product or storage bin discharging system adopts the manual button switch mode, which uses manual manual control of the opening or closing of the finished material door to realize the discharging. The existing discharging method has the following disadvantages:

1. This kind of silo has a single discharging method. During continuous production, the operator needs to continuously touch the control button by hand, which is highly labor-intensive. Take a 500-type water stabilization station as an example: the rated production capacity is 500 tons/hour. If a 50-ton truck is used for continuous shipment, 10 vehicles should be loaded per hour, and one vehicle will be loaded every 6 minutes on average. The finished product silo discharges 3 tons each time, and the operator needs to manually click the button switch 15 times within a minute of loading, not including the operation of manually ringing the bell every time the car is full, which is easy to fatigue.

2. Frequent jogging of the button switch will also shorten the service life of the switch and increase the failure rate and maintenance cost. In terms of overall use, it not only reduces the work efficiency, but also causes fatigue of the staff, and also affects the continuity of construction and production.

3. Lack of necessary protection functions, easy to misuse, and there is a greater safety hazard. For example: in the process of continuous production, due to operational errors, the storage bin may overflow too much, resulting in damage to the transport vehicle; The transport vehicles entering the station to receive materials are smashed by the discharged materials, and even hurt people, etc., dangerous situations occur from time to time.

With reference to Figures 1 to 5, a method for controlling automatic discharging of finished product silos of factory mixing equipment adopts the above-mentioned automatic discharging system of finished product silos of factory mixing equipment, which specifically includes the following;

Firstly, the vehicle detection control method is used to detect the position of the vehicle to realize the automatic unloading of the vehicle from the silo. Combined with the material level detection system, the automatic distribution of the finished product silo is realized, so as to realize the automatic discharge control of the finished product silo.

The vehicle detection control method includes the following steps:

Step A1, close the first material level master switch 12, connect the rectifier device 11 to the vehicle detection system, and convert the current of the regulated power supply 1 to DC through the rectifier device 11 to prepare for the start of the vehicle detection system.

In step A2, the second material level master switch 511 is closed, the first relay 521 and the first vehicle detection sensor 531 are energized, and the first relay 521 controls the first relay electric shock switch 623 to close.

Step A3, after the vehicle is in place, go to Step A4; if the vehicle is not in place, go to Step A6;

In step A4, after the first vehicle detection sensor 531 and the second vehicle detection sensor 541 sense the vehicle information, the second relay 542 is energized, and the second relay 542 controls the second relay contact switch 624 to close, and the oscillator circuit 622 obtains power; after the oscillator circuit 622 is powered on, it goes to step A5.

Step A5, after the oscillator circuit 622 is powered on, the oscillator circuit 622 starts to work and uses the generated pulse signal to make the first time relay electric shock switch 551 close; after the first time relay electric shock switch 551 is closed, the first material gate induction circuit 55 The third relay 552 inside is energized; after the third relay 552 is energized, it controls the first automatic switch 45 to close, thereby realizing the automatic opening of the warehouse door of the finished product warehouse.

After the oscillator circuit 622 is powered off, the oscillator circuit 622 is powered off. The time oscillator in circuit 622 stops working.

After the time oscillator, the third relay 552 is de-energized. After the third relay 552 is de-energized, the first automatic switch 45 is turned off, and the process of automatically opening the door of the finished product silo stops.

The detection method of the material level detection system includes the following steps: Step B1, after the material level detection circuit 6 is energized, when the material level detection sensor 611 detects that the material reaches the warning position, the material level detection sensor 611 controls the fourth relay 612.

The material level detection sensor 611 in the present invention is installed at 80% of the silo capacity scale in the finished product silo of the factory mixing equipment. The reason is that when the material level detection sensor 611 detects that the material reaches the warning position, the batching circuit 63 The fourth relay electric shock switch 631 is disconnected, and the batching mechanism stops the batching work. However, on the conveyor belt mechanism between the batching mechanism and the finished product silo, there are materials prepared by the batching mechanism, and the conveyor belt mechanism is constantly rotating and conveying. The start and stop will affect the service life.

After the conveyor belt mechanism transports the remaining prepared finished materials into the finished product silo, the finished product silo is nearly full, which ensures that the finished product silo will not overflow.

Example 3

In the automatic discharging system of the finished product silo of the above-mentioned factory mixing equipment, a pulse circuit composed of a time relay (or a timer is used to form a pulse circuit in the PLC program) is added to the switch control circuit of the silo door of the finished product silo. By adjusting the pulse width, the opening and closing time of the finished product storage bin door is automatically controlled.

In this system, the material level detection sensor in the finished product silo (the material level detection sensor is a very common device, which is a photoelectric diffuse reflection sensor) is used to detect the material level in the silo reaching 80% of the silo volume.

When the equipment in the automatic unloading system of the present invention starts continuous production, the finished mixed material transport vehicle enters the receiving area, and the automatic unloading function is activated after the first vehicle detection sensor and the second vehicle detection sensor detect that the vehicle is in place, The finished product silo is automatically discharged to complete the loading of the vehicle finished product mixture. When the transport vehicle leaves the loading area, the first vehicle detection sensor and the second vehicle detection sensor close the silo door automatic switch device to supply power, and the silo door is closed and locked. Waiting for the next car in place to pick up the material, and so on, continuous production. At this time, the batching system is always working and feeding the finished product silo through the conveyor belt mechanism.

When a special situation occurs, the receiving vehicle is delayed in place. At this time, the material level detection sensor will start and automatically control the batching mechanism (excluding the aggregate belt and stirring equipment) to stop running after the finished mixture reaches the warning position of the silo to ensure that The material in the silo does not overflow and is locked at the same time until it is normal, and the production process can be restarted. When cleaning or repairing the equipment, you can use the switch (manual/automatic) to release the automatic discharge function. The storage bin door can be opened and closed by manual control.
