TECHNICAL FIELD

[0001] The patent application belongs to the technical field of metal smelting, and more particularly relates to a system for uniformly discharging vanadium slag and additional agents in a vanadium extraction process from vanadium-titanium magnetite. BACKGROUND

[0002] Vanadium is an important additive in steel. When a certain proportion of vanadium is added to steel, the elasticity and strength of the steel can be greatly enhanced, and the wear resistance and burst resistance can also be enhanced. Therefore, vanadium-containing steel is widely used in key fields such as people's livelihood construction projects, military special equipment, aerospace industry, and civil industry. At present, the main raw material for vanadium extraction is vanadium-titanium magnetite. Vanadium-titanium magnetite is subjected to iron smelting, steel smelting, and other processes to obtain vanadium-containing crude slag. The vanadium-containing crude slag is crushed and screened to select iron to obtain vanadium-containing fine slag. The vanadium-containing fine slag is mixed with a certain proportion of additional agents and then subjected to roasting to extract vanadium, thereby realizing the process of extracting vanadium from vanadium-titanium magnetite.

[0003] At present, the traditional vanadium slag and additional agent discharging device has problems such as uneven discharging, material blockage, and inaccurate monitoring during material processing, resulting in low material ratio accuracy and low vanadium extraction efficiency. CONTENT OF THE UTILITY MODEL

The height of the low-level alarm is lower than the upper end height of the pressure-reducing cone, and the cross-sectional area of the pressure-reducing cone gradually increases from top to bottom.

[0007] The system further comprises an intelligent discharging control module, which comprises a controller and a discharging actuator. The controller is connected to the discharging actuator, the rapping device, the high-level alarm, and the low-level alarm. The high-level alarm and the low-level alarm can form a sensor system, which can also be referred to as an alarm system.

[0008] Further, the discharging bin is cylindrical, and the discharging port is arranged at the center of the bottom of the discharging bin.

[0009] Further, the discharging port is rectangular, the outer diameter of the pressure-reducing cone is greater than the width dimension of the discharging port, and the outer diameter of the pressure-reducing cone is less than the length dimension of the discharging port.

[0010] Further, two lower hoppers are arranged along the length direction of the lower outlet, and the two lower hoppers are symmetrically arranged on the two sides below the pressure reducing cone.

[0011] Further, two vibrators are arranged on the corresponding lower hoppers, and the two vibrators are arranged on the sides away from each other of the two lower hoppers.

[0012] Further, the high-level alarm and the low-level alarm are both non-contact sensors.

[0013] Further, the vibrator is a variable frequency vibrator.

[0014] Further, the pressure reducing cone is a conical member, and the lower hopper is a quadrangular pyramid member.

[0015] Due to the adoption of the above technical scheme, the present application has the following beneficial effects:

[0016] The device system is provided with a pressure reducing cone with a gradually increasing cross-sectional area from top to bottom in the stock bin, which can uniformly disperse the materials to the lower outlet through the outer peripheral wall of the pressure reducing cone, and the materials are smoothly guided to the lower side of the stock bin through the lower hopper, thereby avoiding the problem of excessive pressure concentration caused by the accumulation of materials in the stock bin, avoiding the blockage of the materials at the lower outlet, realizing the accurate monitoring of the material level in the stock bin and the stable discharge of the vanadium slag, improving the precision of the vanadium slag discharge amount, and uniformly discharging the materials, which is convenient for ensuring the proportioning accuracy of the subsequent vanadium extraction raw materials, maintaining the accurate proportioning of the fine slag and the additive, improving the vanadium extraction efficiency, and greatly improving the vanadium extraction efficiency.

[0020] The present application will be further described in detail below in combination with the embodiments.

[0021] A kind of efficient control vanadium slag and additive uniform discharge system, such as Figure 1, including a discharging bin 1, a discharging port 11 arranged at the bottom of the discharging bin 1, a pressure-reducing cone 2 arranged in the discharging bin 1 and above the discharging port 11, a discharging hopper 3 connected below the discharging port 11, a rapping device 4 arranged on the outer wall of the discharging hopper 3, a high-level alarm 51 arranged on the inner side of the discharging bin 1 at the upper part, a low-level alarm 52 arranged on the inner side of the discharging bin 1 at the lower part, the height of the low-level alarm 52 is lower than the upper end height of the pressure-reducing cone 2, and the cross-sectional area of the pressure-reducing cone 2 gradually increases from top to bottom.

[0022] The discharging bin 1 is used for receiving materials and is made of high-strength wear-resistant material to ensure long-term stable operation. The pressure-reducing cone 2 is designed in a conical shape and is precisely machined to ensure uniform change of the cross-sectional area, which is used to uniformly disperse the materials to the outer periphery. The discharging hopper 3 is used to receive the materials falling at the discharging port 11 to ensure uniform distribution of the materials. The rapping device 4 is controlled by frequency conversion, which intelligently adjusts the rapping force according to the material state to prevent material accumulation. The high-level alarm 51 and the low-level alarm 52 are used to monitor the material level, both of which use non-contact sensors to improve detection accuracy and reliability, and have sound and light alarm functions.

[0023] It also includes an intelligent discharging control module, which includes a controller connected to the rapping device 4, the high-level alarm 51 and the low-level alarm 52. The high-level alarm 51 and the low-level alarm 52 can form a sensor system, also known as an alarm system.

[0024] The controller is also connected to a discharging actuator for discharging materials, such as a discharging machine or a discharger. The controller intelligently analyzes and decides according to the data fed back by the high-level alarm 51 and the low-level alarm 52 to control the discharging actuator to discharge materials. The high-level alarm 51 is used to obtain and send first alarm information to the controller, and the low-level alarm 52 is used to obtain and send second alarm information to the controller.

[0025] In the intelligent discharging control module: the controller uses commercially available control devices, which can be a single-chip microcomputer, a PLC control system, or other control elements and control modules, and does not have specific requirements. As long as the controller can automatically adjust the working frequency of the rapping device 4 according to the flow rate and pressure change of the materials, it can complete the basic control function, which is not the core innovation point of this patent and does not require additional and complex control functions. The existing technology can be used.

[0026] In the specific design of the system, the discharging bin 1 is a cylindrical member, and the discharging port 11 is arranged at the center of the bottom of the discharging bin 1. The discharging port 11 is rectangular, the outer diameter of the pressure-reducing cone 2 is greater than the width dimension of the discharging port 11, and the outer diameter of the pressure-reducing cone 2 is less than the length dimension of the discharging port 11.

[0027] The two lower hoppers 3 are arranged in a length direction of the lower outlet 11 and symmetrically distributed on two sides below the pressure reducing cone 2.

[0028] The two rappers 4 are respectively arranged on the corresponding lower hoppers 3 and connected to the opposite sides of the two lower hoppers 3.

[0029] The rapper 4 is a frequency conversion rapper, the pressure reducing cone 2 is a conical member, and the lower hopper 3 is a quadrangular pyramid member.

[0030] In use, the controller sends a discharging signal, the discharging executor (discharging machine or discharging device) starts discharging, the material enters through the discharging bin 1, is distributed by the pressure reducing cone 2, and the material falling at the lower outlet 11 falls into the lower hopper 3; if the discharging is not smooth, the controller sends a rapping signal during the period, and the rapper 4 raps the lower hopper 3 to avoid material accumulation. The high-level alarm 51 and the low-level alarm 52 monitor the material level in real time and send a monitoring signal to the controller to remind the amount of material in the discharging bin 1.

[0031] Therefore, the novel efficient control vanadium slag and additive uniform discharging system has the advantages of efficient, accurate, uniform and stable vanadium slag and additive discharging, and has significant technical advantages and application prospects.
