Description

Technical Field

[0001] This invention relates to the field of automation technology for continuous sintering production processes in the metallurgical industry, and particularly to an intelligent volumetric flow rate measurement and control device for powder materials in the sintering batching process. Background Technology

[0002] In the sintering production process of the metallurgical industry, various types of powder materials need to be continuously batched according to the process settings and transported to a large mixer for mixing to obtain a sintering mixture. This mixture is then directly fed onto the sintering machine and sintered at high temperatures to produce the final sintered ore. Ideally, the batching process should have minimal fluctuations in the flow rate of each material and maintain a constant proportion. Large fluctuations in the flow rate of each material will significantly affect the stability of the mixed material ratio, causing fluctuations in downstream production and greatly impacting the quality and efficiency of the sintered ore. Currently, the automatic batching device used in this process employs a dual closed-loop cascade control system combining a disc feeder and an electronic belt scale. However, due to the inherent large inertia of the equipment and the lag in measurement information, the closed-loop control system has consistently exhibited poor stability, resulting in significant fluctuations in the controlled material flow rate. This is detrimental to stable and efficient production, and can even lead to equipment malfunctions, disrupting normal production and significantly increasing maintenance frequency and costs. Therefore, there is an urgent need to develop an intelligent flow measurement and control device for powder materials to address these issues. Summary of the Invention

[0003] This invention discloses an intelligent volumetric flow rate measurement and control device for powder materials in sintering batching processes. It primarily addresses numerous problems caused by the inherent large inertia of the equipment and the lag in measurement information in existing batching systems and structures. This device plays a crucial role in improving the production efficiency and effectiveness of metallurgical sintering batching processes, thereby achieving stable and efficient production of sintering machines.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] The intelligent volumetric flow rate measurement and control device for powder materials in a sintering batching process is characterized by primarily consisting of an inclined conveyor belt with automatically controllable linear velocity, a powder material cross-section shaping unit, and an intelligent calculation and control unit. The inclined conveyor belt receives the powder material output from the lower outlet of the batching silo. A speed-controllable motor first drives the idler rollers to rotate, simultaneously driving the belt and pulling the material forward. When it reaches the cross-section shaping unit, the cross-section of the material is shaped into a trapezoidal or triangular shape before being output. Furthermore, the intelligent calculation and control unit automatically calculates and controls the volumetric flow rate of the powder material using intelligent software.

[0006] Compared with the prior art, the beneficial technical effects of the present invention are as follows:

[0007] The existing batching system suffers from high inertia of the disc feeder and lagging electronic belt scale measurement information, resulting in poor stability of the closed-loop control system. The controlled material flow rate fluctuates significantly, hindering stable and efficient production, and sometimes even causing equipment failures that disrupt normal operation, leading to a substantial increase in maintenance frequency and costs. This invention provides an intelligent volumetric flow rate measurement and control device for powder materials in the sintering batching process, solving the problems of unstable and fluctuating material flow rate control in the original batching system. This invention employs an inclined conveyor belt, a powder material cross-section shaping unit, and its intelligent calculation and control unit. The technical solution for constructing the intelligent volumetric flow rate measurement and control device is a first in the field, featuring integrated electromechanical equipment and intelligent measurement and control. It plays a crucial role in improving the production efficiency and effectiveness of metallurgical sintering batching processes, meeting the technical requirements of green, low-carbon, and high-quality development in the new era.

[0011] like Figure 1 As shown, an intelligent volumetric flow rate measurement and control device for powder materials in a sintering batching process consists of an inclined conveyor belt (1), a powder material cross-section shaping unit (2), and an intelligent calculation and control unit (3). The inclined conveyor belt (1) is driven by a motor (4) to rotate the idler roller (5) and move the belt forward. Its linear velocity is measured by a speed measuring device (8) to determine the rotational speed of the idler roller. Based on parameters such as the idler roller circumference and belt thickness, the intelligent calculation and control unit (3) calculates the belt's linear velocity using intelligent software. Simultaneously, the inclined conveyor belt (1) receives the powder material output from the lower outlet (6) of the batching silo and moves the material forward.

[0012] like Figure 2As shown, the powder material output from the lower outlet (6) of the batching silo is driven forward by the inclined conveyor belt (1). When it reaches the position of the powder material cross-section shaping unit (2), it is shaped into a trapezoidal (7) cross-section by the cross-section shaping unit (2) before being output. Further, based on the linear velocity of the belt and the cross-section of the output material, the volumetric flow rate of the powder material is calculated by the intelligent calculation and control unit (3).

[0013] The working process of this invention is as follows:

[0014] Please see Figure 1 and Figure 2 A smart volumetric flow rate measurement and control device for powder materials in a sintering batching process is disclosed, comprising an inclined conveyor belt, a powder material cross-section shaping unit, and a smart calculation and control unit. The inclined conveyor belt is driven by a speed-controllable motor that rotates idler rollers, propelling the belt forward. Its linear velocity is first measured by a speed measuring device based on the rotational speed of the idler rollers, and then calculated by the smart calculation and control unit using software based on parameters such as the idler roller circumference and belt thickness. Simultaneously, the inclined conveyor belt receives the powder material output from the lower outlet of the batching silo. When the material reaches the powder material cross-section shaping unit, it is shaped into a trapezoidal or triangular cross-section for output. Further, based on the belt's linear velocity and the cross-section of the output material, the smart calculation and control unit calculates the volumetric flow rate of the powder material using intelligent optimization software. When the linear velocity and volumetric flow rate deviate from the set values, the smart calculation and control unit intelligently optimizes and adjusts the motor's rotational speed to minimize the deviation, thereby achieving automatic calculation and control of the linear velocity and volumetric flow rate.

[0015] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention should fall within the scope of protection of the present invention.
