Embodiment 1

[0062] figure 2 It is a schematic flow chart of a batching control method proposed by the present invention, which is applied to the batching control system, wherein the batching control system includes: a transmission belt and a material tank arranged above the transmission belt, and a scale is arranged below the weighing section of the transmission belt. A load sensor and a speed sensor, a feeding device is provided below the material tank to control the amount of material discharged in the material tank, and a transmission belt transfers the material to the mixing drum for mixing. The method includes the following steps:

[0063] Step S101: Obtain the target ingredient amount;

[0064] The target batching amount can be manually input into the batching control system by the staff, or transmitted to the batching control system through other devices. The target batching amount is the weight of the material discharged by the batching control system within a unit time, for exam...

Embodiment 2

[0076] In another embodiment of the present invention, as image 3 As shown, step S102 in the above embodiment determines the target transmission speed of the transmission belt according to the target batching amount, including the following steps:

[0077] Step S1021: Obtain the corresponding relationship between the preset target ingredient amount interval and the transmission speed. The corresponding relationship includes a plurality of target ingredient amount intervals, and each target ingredient amount interval corresponds to a transmission speed;

[0078] The corresponding relationship between the target batching quantity interval and the transmission speed can be shown in the following table:

[0079] serial number Target ingredients range transfer speed 1 0~SP1 (0~20% of the maximum SP of the target ingredient amount) V1(V*15%) 2 SP1~SP2 (20~40% of the maximum SP of the target ingredient amount) V2(V*30%) 3 SP2~SP3 (40~60% of the ma...

Embodiment 3

[0091] In another embodiment of the present invention, as Figure 4 As shown, step S103 in the above embodiment may include the following steps:

[0092] Step S1031: generating a speed control signal according to the target transmission speed;

[0093] In step S102 in the above embodiment, the target conveying speed corresponding to the target ingredient amount can be determined, and a speed control signal can be generated according to the target conveying speed.

[0094] Step S1032: Send the speed control signal to the driving motor of the transmission belt.

[0095] Send the speed control signal obtained in the above steps to the driving motor of the transmission belt, and the driving motor will make the transmission belt run according to the target transmission speed corresponding to the speed control signal according to the speed control signal, so that the materials on the transmission belt will follow the target transmission speed Transported by the transport belt.

Abstract

An embodiment of the invention discloses a proportioning control method a proportioning control system, which can be used for material proportioning of sintered materials. According to the proportioning control method and the proportioning control system, for any material from a variety of materials which needs to be mixed, the discharging of the material can be controlled in a double speed regulation manner, and the conveying speed of a conveying belt can be adaptive to the discharging amount of a feeding device through independently adjusting the conveying speed of the conveying belt and the discharging amount of the feeding device, so that the phenomenon that materials are stacked or run out on the conveying belt when the proportioning amount is greatly increased or decreased can be effectively prevented, therefore the proportioning amount of each material of the finally obtained mixture can be more precise; in the process of controlling the proportioning of each material, operation steps are simple, a precise proportioning amount can be obtained in a shorter time, the time required for the proportioning control system to reach a steady state is reduced, and material proportion of the sintered materials can be precisely controlled.

Description

technical field [0001] The invention relates to the technical field of sintering, in particular to a batching control method and system. Background technique [0002] The sintering process is an important link in the smelting technology, including batching, water mixing, sintering and other processes. Among them, the batching process is to fully mix various raw materials in proportion to form a mixture and enter the sintering machine, and then undergo high-temperature sintering and other related processes to form sinter with stable physical and chemical properties and suitable for blast furnace smelting. [0003] The aforementioned batching process is usually completed by a batching control system. Such as figure 1 As shown, the batching control system includes a material tank 1, a feeding device 2 and a transmission belt 5 running at a constant speed, wherein the feeding device 2 can control the output of the material tank 1, and a certain raw material is housed in the ma...
