Description

Technical Field

[0001] The utility model relates to the technical field of slag processing, in particular to an ultra-fine slag powder air separation component. Background Art

[0002] Slag, also known as slag, is a by-product produced from the metallurgical process, especially the blast furnace iron-making process. During iron-making, the main component of iron ore, iron oxide, is reduced to metallic iron under high temperature conditions, while other impurity elements contained in the ore, such as silicon dioxide (SiO2) and aluminum oxide (Al2O3), react with the added flux such as lime to form a molten substance with silicates and aluminosilicates as the main components. When these high-temperature melts are rapidly cooled (quenched), a loose, porous granular solid is formed, namely slag.

[0003] After searching, the patent number "CN220920002U" mentioned in the text that "the utility model discloses a slag fine powder air separation component, which relates to the field of slag processing technology, including an air separation box, the interior of the air separation box is divided into a first cavity and a second cavity by a partition, and a mounting hole is opened in the center of one side of the partition; through the air inlet pipe, the fan, the equipment box and the air separation pipe, when the fine powder in the slag needs to be air-separated, the slag is sent to the first conveyor through the guide pipe, and after the first conveyor is started, the slag is sent to the mid-air and falls into the receiving box, and the slag continues to fall from the air separation pipe. During the falling process, the air inlet pipe is connected to the external environment, and the fan is started to generate wind force, and the external air is introduced into the equipment box through the air inlet pipe, and then enters the air separation pipe through the air guide pipe to flow upward from the bottom of the air separation pipe, taking away the fine powder and continuing to flow out from the air outlet pipe into the relevant container to collect the fine powder. In this way, the contact time between the airflow and the slag can be significantly prolonged, and the fine powder in the slag can be further reduced. The powder is fully air-selected to enhance the air-selection effect of the slag fine powder. "When it is used, through the air inlet pipe, the fan, the equipment box and the air-selection pipe, when the fine powder in the slag needs to be air-selected, the slag is sent to the first conveyor through the guide pipe. After the first conveyor is started, the slag is sent to the mid-air and falls into the receiving box. The slag continues to fall from the air-selection pipe. During the falling process, the air inlet pipe is connected to the external environment, and the fan is started to generate wind force, and the external air is introduced into the equipment box through the air inlet pipe, and then enters the air-selection pipe through the air guide pipe to flow upward from the bottom of the air-selection pipe, taking away the fine powder and continuing to flow out from the air outlet pipe into the relevant container to collect the fine powder. In this way, the contact time between the air flow and the slag can be significantly extended, the fine powder in the slag can be fully air-selected, and the air-selection effect of the slag fine powder can be enhanced. However, the air-selection component lacks the wind speed control function, which will affect the sorting efficiency and accuracy, and a large amount of dust will be generated during the air-selection process, which will affect the environment.

[0004] To this end, we provide a slag ultrafine powder air separation component to solve the above problems. Utility Model Content

[0005] The present application provides a slag ultrafine powder air separation component, which solves the problem that the air separation component lacks wind speed control function, which will affect the separation efficiency and accuracy.

[0006] The present application provides a slag ultrafine powder air separation component, comprising an air separation box and a working mechanism, wherein a conveyor belt is installed inside the air separation box, and a working mechanism is installed on one side of the air separation box;

[0007] The working mechanism includes a control component installed on the outside of the air separation box, a driving component is installed on the top of the air separation box, a control component is installed inside the driving component, a regulating component is installed on one side of the control component, and a filtering component is installed on the outer wall of the air separation box.

[0008] Preferably, the control assembly comprises a control panel installed on the outside of a winnowing box, a feed port is provided on the surface of the winnowing box, and a collection box is installed on the other side of the winnowing box.

[0009] Preferably, the driving assembly comprises a motor installed on the top of the air separation box, one side of the motor is electrically connected to a PWM controller, and the bottom end of the motor is flatly keyed to a fan.

[0010] Preferably, the control component comprises a circuit board installed inside the PWM controller, a microprocessor is welded on the surface of the circuit board, and a carrier signal generator is arranged on one side of the microprocessor.

[0011] Preferably, the regulating component includes a comparator installed on the outer side of a circuit board, a pulse modulator is arranged on the other side of the microprocessor, and an output driver is arranged above the carrier signal generator.

[0012] Preferably, the filter assembly comprises a purification box installed on the outer wall of the air separation box, and an exhaust port is opened on the surface of the purification box.

[0013] Preferably, a purification component is installed inside the purification box, and the purification component includes an exhaust fan installed inside the purification box, a fiber filter plate is installed on one side of the exhaust fan, and an activated carbon filter plate is installed on the other side of the fiber filter plate.

[0014] It can be seen from the above technical scheme that the present application provides a slag ultrafine powder air separation component. When in use, the slag is introduced into the air separation box through the feed port, and then the conveyor belt transports the slag. Then the motor is started by controlling the control panel, and the motor controls the fan to rotate, so as to air separate the slag. In this process, the PWM controller controls the current of the motor, so that the motor can adjust the output power according to different slag. During the air separation process, the exhaust fan sucks the dust generated in the air separation process into the purification box and processes it through the filtration step. First, the dust will pass through the fiber filter plate. This stage mainly intercepts larger particles and some fine dust. Subsequently, the filtration process advances to the activated carbon filter plate, where the adsorption characteristics of activated carbon are used to further remove tiny particles and absorb harmful gases or odors, ensuring that the air purification is more thorough. After these two layers of high-efficiency filtration, the fresh and harmless air is finally safely discharged to the external environment through the exhaust port, ensuring the air quality and environmental safety of the working area, and completing the use of the air separation component.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. Through the setting of the working mechanism, when in use, the carrier signal generator generates a rectangular wave signal with a fixed frequency, and then the comparator compares the reference signal representing the expected output signal amplitude with the carrier signal. When the reference signal is higher than the carrier signal, the PWM output is high level, otherwise it is low level. By adjusting the amplitude of the reference signal, the high level time can be changed, and then the output average current can be adjusted. After the PWM signal is amplified by the output driver, it is used to control the opening and closing of the motor. During the high level period, the switch is turned on and the power supply provides energy to the load. During the low level period, the switch is turned off and the energy transmission stops, thereby changing the output power of the motor, so as to adjust the wind speed according to actual needs. In addition, during the wind selection process, the purification box filters the dust generated during the sorting, thereby reducing the pollution to the surrounding environment;

[0017] 2. Through the setting of purification components, the exhaust fan inhales the dust generated in the air selection process and processes it through the filtration step. First, the dust will pass through the fiber filter plate, which mainly intercepts larger particles and some fine dust. Then, the filtration process advances to the activated carbon filter plate, where the adsorption characteristics of activated carbon are used to further remove tiny particles and absorb harmful gases or odors, ensuring more thorough air purification. After these two layers of high-efficiency filtration, the fresh and harmless air is finally safely discharged to the external environment through the exhaust port, ensuring the air quality and environmental safety of the working area.

[0018] In summary, the present application regulates the wind speed according to actual needs, and during the air separation process, the purification box filters the dust generated during the sorting, thereby reducing pollution to the surrounding environment. BRIEF DESCRIPTION OF THE DRAWINGS
