Description

A sintering raw material automatic ratio mixing test system

technical field

The utility model relates to a proportioning system, in particular to an automatic proportioning and mixing test system for sintering raw materials.

Background technique

Ironmaking and sintering production has the characteristics of uninterrupted process, long time consumption and complicated process. Even if the process parameters of each link are monitored in real time during the material transfer process, it is still very difficult to adjust the process parameters in real time according to the fluctuation of sintering raw materials and stabilize the index parameters of sintered finished ore. To find out the correspondence between the chemical composition parameters of the sintering raw materials, the technological parameters of the sintering process, and the index parameters of the sintered finished ore, technicians usually collect the above data through sintering cup experiments and then analyze and calculate them. The premise of carrying out the sintering cup experiment is to prepare a small amount of sintering mix. The preparation process is as follows: according to the formula, increase or decrease a single raw material in a single container, and weigh to determine the weight; pour various raw materials with a determined weight into the same container and mix; add water to the mixture until the moisture content meets the formula requirements; The water-containing mixture is put into the mixing cylinder to continue mixing and granulation and agglomeration. It can be seen from the above process that the preparation process requires a large number of people and is time-consuming and labor-intensive. Once there are human errors such as excessive water addition and improper mixer parameter setting, it will affect the progress of the sintering cup experiment and cause waste of raw materials.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.

Figure 1 is a structural diagram of the automatic proportioning and mixing test system for sintering raw materials.

As shown in Figure 1, in this embodiment, the automatic proportioning and mixing test system for sintering raw materials includes: several hoppers 4, several vibrating feeders 5, load cells 6, conveyor belts 7, conveyor belt motors 2, and mixing cylinders 15 , mixing drum motor 13, water tank 9 and water pipe 11.

The sintering raw materials, such as iron ore powder, coke powder, limestone powder, sintering return ore particles, etc., are loaded into the hopper 4 according to the type, and a single hopper 4 only holds a single type of sintering raw material. Each hopper is respectively provided with a material level sensor 3, which is equivalent to a limit alarm switch. When the height of the sintered raw material in the hopper 4 is lower than the height of the material level sensor, it indicates that the material level of the raw material in the hopper 4 exceeds the limit, and the user is reminded to add or subtract the corresponding sintered raw material in time.

The hopper 4 corresponds to the vibrating feeder 5 one by one, and the discharge port below each hopper 4 is closed and connected to the feeding port of each vibrating feeder 5 respectively. The vibrating feeder 5 storage bin, adjust the installation inclination angle of the vibrating feeder 5, so that the sintered raw material does not slide out from the vibrating feeder 5 outlet when the vibrating feeder 5 is not powered. When the vibrating feeder 5 is energized and running, it vibrates continuously at a specified frequency (the frequency value corresponds to the feeding amount), and the sintered raw materials are vibrated out of the storage bin through the discharge port under the action of vibration. At the same time, the raw materials for sintering in the hopper 4 continuously slide down through the feed inlet and enter the storage bin under the vibration of the vibrating feeder 5 .

The weighing sensor 6 is located below the discharge port of the vibrating feeder 5 and above the conveyor belt 7 . The sintered raw material falls on the load cell 6 in the form of free fall after vibrating out from the discharge port of the vibrating feeder 5 . Load cell 6 can weigh the weight of each vibration blanking and the accumulated blanking weight. Of course, the speed of blanking can be obtained through calculation. In order to prevent the sintering raw material from accumulating on the load cell 6, the load cell 6 is installed in an inclined posture. It is advisable for the load cell 6 to be installed at an angle of 30° to 60° with the ground, and the optimum angle is 45°.

The mixing cylinder 15 starts to rotate in the forward direction driven by the mixing cylinder motor 13, and performs mixing operations on various types of sintering raw materials. After the mixing cylinder 15 rotates for a period of time, the pressure water pump 10 starts and the water in the water tank 9 is pumped into the mixing cylinder 15 to mix with the sintering raw materials through the water pipe 11. At the same time, the mixing cylinder 15 continues to rotate in the forward direction. When the forward rotation time of the mixing barrel 15 reaches the value specified by the user, the mixing barrel 15 starts to rotate in the reverse direction driven by the mixing barrel control motor 13, and the mixed ore after mixing is discharged through the outlet of the mixing barrel 15. .
