Detailed Description
As shown in fig. 1-3, an automatic control system for fertilizer raw materials capable of preventing material blockage comprises a raw material conveyor 1, a double-shaft mixer 2, a lifter 3 and a granulation system 4 which are connected in sequence; the double-shaft stirrer 2, the hoister 3 and the granulating system 4 are in signal connection with a DCS control system 5, and the DCS control system 5 is in signal connection with the raw material conveyor 1; the discharge end cover of raw materials conveyer 1 is equipped with dust cover 6, and the internally mounted of dust cover 6 has the clearance mechanism that takes place relative rotation with raw materials conveyer 1. The bottom of the feed end of the raw material conveyor 1 is provided with a scale 7.
Specifically, the cleaning mechanism comprises a motor 61 and a cleaning brush 62 which are fixed on the inner wall of the dust cover 6, one end of the cleaning brush 62 is in transmission connection with the output end of the motor 61, and the bristles of the cleaning brush 62 are in contact with the surface of the raw material conveyor 1; the other end of the cleaning brush 62 is arranged in a clamping groove on the inner wall of the dust cover 6.
In order to facilitate the falling of the raw materials on the raw material conveyor 1, the raw material conveyor 1 is arranged obliquely, and the height from the feeding end of the raw material conveyor 1 to the ground is greater than the height from the discharging end of the raw material conveyor 1 to the ground. The inclination angle of the raw material conveyor 1 is 10-30 degrees.
The operation of the device is described in detail below with reference to the drawings in the examples.
After being added into a raw material conveyor 1, the raw materials are metered by a metering scale 7, conveyed into a double-shaft stirrer 2 by the raw material conveyor 1 to be mixed, and then conveyed into a granulator of a granulation system 4 by a bucket elevator 3 to be granulated and then enter a sieving system for sieving.
When the abnormal current of the double-shaft stirrer 2 is greater than or equal to 7A, the DCS control system 5 receives the signal and controls the raw material conveyor 1 to stop feeding through a program. When the abnormality of the double-shaft mixer 2 is processed and the current is less than or equal to 6A, the DCS control system 5 receives the signal and controls the material conveyor 1 to feed again through a program.
When the current of a granulator of the granulating system 4 is more than or equal to 450A due to abnormal current, the DCS control system 5 receives the signal and controls the raw material conveyor 1 to stop feeding through a program. When the granulator current is less than or equal to 350A, the DCS control system 5 receives the signal and controls the raw material conveyor 1 to feed again through a program. Similarly, when the elevator is abnormal, the DCS control system 5 receives the signal and controls the raw material conveyor 1 to stop feeding through the program, and when the elevator returns to normal, the DCS control system 5 controls the raw material conveyor 1 to feed again.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and should not be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention should be included within the scope of the present invention.
