A coal blending system and process

Abstract

The invention discloses a coal blending system and process. The coal blending system comprises a transport vehicle, a vehicle guide mechanism, a weighing mechanism, a plurality of feeding mechanisms, a transfer mechanism and a monitoring mechanism. The transport vehicle is used for transporting coal, the vehicle guide mechanism is used for guiding the transport vehicle to unload, the weighing mechanism is used for metering the mass of the coal transported by the transport vehicle, the feeding mechanisms are used for receiving the coal transported by the transport vehicle and controlling the feeding process, the transfer mechanism is used for transferring the coal fed by the feeding mechanisms, and the monitoring mechanism is used for commanding and monitoring the whole system to operate. The transport vehicle is matched with the feeding mechanisms, the feeding mechanisms are connected with the transfer mechanism, and the monitoring mechanism is electrically connected with the weighing mechanism, the feeding mechanisms and the vehicle guide mechanism. According to the coal blending system and process, under automatic intelligent control and whole-process monitoring of the monitoring mechanism, full-automatic operation of the whole coal blending system is achieved. In addition, the vehicle guide mechanism can automatically command the transport vehicle to transport the specific coal to corresponding positions without on-scene command of people, and therefore labor cost is saved.

Description

technical field [0001] The invention relates to the technical field of coal blending devices, in particular to a coal blending system and process. Background technique [0002] The existing coal blending system mainly has the following disadvantages: 1. Some of the current coal blending systems use on-site operations, using manual coal blending, which not only wastes manpower, material resources, and financial resources, but also has very low production efficiency , is also prone to human error. 2. The existing coal blending system is to directly transport several different coals by truck, and then directly put them together for stirring. This coal blending method cannot accurately feed materials, let alone guarantee the quality of coal blending. 3. The existing coal blending system feeds coal through a weighing belt conveyor, and then transfers it to a belt conveyor for direct loading. This coal blending method does not mix different coals evenly, and cannot guarantee the ...

[0002] The existing coal blending system mainly has the following disadvantages: 1. Some of the current coal blending systems use on-site operations, using manual coal blending, which not only wastes manpower, material resources, and financial resources, but also has very low production efficiency , also prone to human error

2. The existing coal blending system is to directly transport several different coals by truck, and then directly put them together for stirring. This coal blending method cannot accurately feed materials, let alone guarantee the quality of coal blending

3. The existing coal blending system feeds coal through a weighing belt conveyor, and then transfers it to a belt conveyor for direct loading. This coal blending method does not mix different coals evenly, and cannot guarantee the overall coal blending quality

4. The existing coal blending system does not integrate the weighbridge system, and there is no vehicle guiding mechanism

The disadvantage of this type of coal blending system is that the coal blending is uneven and the production volume is small;

[0005] The second type is coal blending by bucket wheel machine. The disadvantage of this type of coal blending system is that the coal blending is very uneven, the hardware requirements are high, and it is difficult to achieve multi-type coal blending;

[0006] The third type is silo coal blending. The advantage of this type of coal blending system is that the coal blending accuracy is high, but the investment is too large and the area occupied is too large.
