Description

Technical Field

[0001] This utility model relates to the field of sintering technology, specifically to a vibrating air separation device. Background Technology

[0002] Currently, the fuel used in sintering batches is generally 0-3mm in size. Studies have shown that controlling the particle size of materials below 0.5mm within a certain range can significantly improve various sintering indicators. In the existing production process, due to the high moisture content, fine particle size, and small particle size difference of the fuel, removing fuel below 0.5mm presents problems such as difficulty in material loosening and easy clogging of pores during the screening process.

[0003] Therefore, there is an urgent need for a vibrating air classifier to solve the problems of material loosening and easy clogging during the screening process when removing small particles from light and fine water-containing materials. Utility Model Content

[0004] The purpose of this utility model is to provide a vibrating air separation device, which aims to solve problems such as difficulty in material loosening and easy clogging of holes during the screening process. The specific technical solution is as follows:

[0005] A vibrating air separation device includes a frame and a feeding device, a vibrating screening device, an air supply device, and a dust removal device disposed on the frame. The feeding device is used to transport materials to the receiving end of the vibrating screening device. A dust removal device is disposed above the vibrating screening device. The air supply device is disposed below the vibrating screening device. The airflow output by the air supply device passes through the vibrating screening device and is discharged by the dust removal device.

[0006] Preferably, the vibrating screening device includes a vibrating screen and a vibration driving mechanism. The vibrating screen is mounted on a frame via the vibration driving mechanism and is driven by the vibration driving mechanism to generate vibration. The dust removal device includes a dust removal pipe and a dust collection hood. The dust removal pipe is connected to the dust collection hood, and the dust collection hood is located above the vibrating screen and the two are flexibly connected.

[0007] Preferably, the vibration drive mechanism includes a vibrator, a connecting seat, and a spring. Multiple connecting seats are provided on both sides of the vibrating screen. The connecting seats are mounted on the frame by springs. The vibrating screen is connected to the vibrator, which is used to drive the vibrating screen to generate vibration.

[0008] Preferably, the feeding device includes a hopper, a roller feeder, and a feed pipe arranged in sequence, with the outlet of the feed pipe connected to the dust collection hood and the outlet of the feed pipe located at the receiving end of the vibrating screen.

[0009] Preferably, the vibrating screen includes a screen body and a screen plate disposed in the screen body, the screen plate is provided with screen holes, and the width of the feed pipe is consistent with the width of the screen plate.

[0010] Preferably, the air supply device includes air boxes, a main air inlet pipe, a blower, and air inlet branch pipes. Multiple air boxes are arranged below the vibrating screen. The air boxes are flexibly connected to the vibrating screen. The main air inlet pipe is connected to the blower. The main air inlet pipe is connected to each air box through air inlet branch pipes.

[0011] Preferably, the main air inlet pipe is equipped with a main pipe valve and a main pipe detection device for detecting air pressure and air speed, and the branch air inlet pipe is equipped with a branch pipe valve and a branch pipe detection device for detecting air pressure and air speed.

[0012] Preferably, the bottom of the air box is provided with an ash discharge valve.

[0013] Preferably, the discharge end of the vibrating screen is provided with a discharge pipe, one end of which is flexibly connected to the discharge end of the vibrating screen, and the other end is connected to a rotary valve.

[0014] The application of the technical solution of this utility model has the following beneficial effects:

[0015] This invention relates to a vibrating air classifier. The material is fed by a roller feeder, and the width of the feed pipe is designed to be equal to the width of the screen plate. This ensures that the material is evenly, flatly, and controllably distributed on the screen plate, meaning all vibrations are effective, eliminating the need for the material to vibrate a certain distance on the screen plate before spreading out, thus improving efficiency. Furthermore, by controlling the vibration frequency and amplitude of the vibrating screen, the material thickness and running time on the screen plate can be effectively controlled. An air box is installed below the vibrating screen for air supply, and a dust collector is installed above for exhaust. The material forms a fluidization effect as it runs on the screen plate. The high-speed airflow further enhances the fluidization and boiling effect, and the negative pressure of the dust collector removes fine particles, achieving the goal of removing small-diameter fuel particles. By adjusting the operating parameters, this vibrating air classifier can remove fuel particles of different target sizes.

[0016] The vibrating air separation device of this utility model adopts a soft connection between the vibrating screening device and the components that do not need to vibrate, thereby minimizing the vibrating mass and saving motor energy consumption. At the same time, the material accumulation at the top of the roller feeder can form a material seal at the feeding point, and a rotary valve is set at the discharge point to prevent air leakage. A ash discharge valve is also set at the air box to prevent air leakage. The above structure can effectively seal the entire device and prevent air leakage and dust overflow.

[0017] This utility model's vibrating air classifier uses a screening method combining vibration and air classification, which can effectively screen light and fine materials with high screening efficiency. In addition, the device provides uniform and flat material distribution, controllable feeding speed, and adjustable frequency and amplitude of the blower, exhaust fan, and vibrating screen. For different materials, the operating parameters can be adjusted to optimize screening efficiency. Finally, the entire device has an independent sealing system, resulting in low air leakage during blower and exhaust processes, no dust overflow, high utilization rate of the air system, and energy saving and environmental protection.

[0023] To facilitate understanding of this invention, a more comprehensive description is provided below, along with preferred embodiments. However, this invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this invention.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0025] Example:

[0026] See Figures 1-2 This embodiment provides a vibrating air separation device, including a frame 1 and a feeding device, a vibrating screening device, an air supply device and a dust removal device disposed on the frame 1. The feeding device is used to transport materials to the receiving end of the vibrating screening device. A dust removal device is provided above the vibrating screening device. The air supply device is disposed below the vibrating screening device. The airflow output by the air supply device passes through the vibrating screening device and is discharged by the dust removal device.

[0027] Specifically, the vibrating screening device includes a vibrating screen and a vibration driving mechanism. The vibrating screen is mounted on the frame 1 via the vibration driving mechanism and is driven by the vibration driving mechanism to generate vibration. The dust removal device includes a dust removal pipe 13 and a dust collection hood 14. The dust removal pipe 13 is connected to the dust collection hood 14, and the dust collection hood 14 is positioned above the vibrating screen with a flexible connection between the two. Figure 1 and Figure 2 As shown in the figure, the flexible connection between the dust collection hood 14 and the vibrating screen is flexible connection 15. By placing the dust collection hood 14 above the vibrating screen and connecting the two with a flexible connection, a good sealing effect can be achieved. The gas output from the air supply device, after passing through the vibrating screen, carries fine particles and is sucked into the dust removal device for further processing, effectively preventing dust from overflowing during the material screening process.

[0028] Furthermore, such as Figure 1 and Figure 2 As shown, the vibration drive mechanism includes a vibrator 7, a connecting seat 16, and a spring 18. Multiple connecting seats 16 are provided on both sides of the vibrating screen. The connecting seats 16 are mounted on the frame 1 by the spring 18. The vibrating screen is connected to the vibrator 7, and the vibrator 7 is used to drive the vibrating screen to generate vibration.

[0029] Preferably, the vibrating screen includes a screen body 5 and a screen plate 6 disposed in the screen body 5. The screen plate 6 is provided with screen holes. The vibrator 7 and the connecting seat 16 are both connected to the screen body 5. The connecting seat 16 is disposed on the frame 1 by a spring 18. The spring has a certain stiffness. After the vibrator 7 is started, the spring can be compressed along the direction of the excitation force, thereby realizing the vibration of the screen body.

[0030] Preferably, in this embodiment, the vibrator 7 is a vibration motor. The vibration motor is arranged at an angle to the vibrating screen to control the vibration direction of the vibrating screen. The vibration motors are symmetrically arranged on both sides of the vibrating screen. When started, the vibration motors on both sides rotate in opposite directions, thereby realizing the linear vibration of the vibrating screen. The vibration motor is frequency-controlled, and the amplitude and frequency of the vibrating screen can be adjusted by changing the frequency.

[0031] Furthermore, the feeding device includes a hopper 2, a roller feeder 3, and a feed pipe 4 arranged sequentially. The outlet of the feed pipe 4 is connected to the dust collection hood 14, and the outlet of the feed pipe 4 is located at the receiving end of the vibrating screen. The connection between the outlet of the feed pipe 4 and the dust collection hood 14 allows the dust generated during material feeding to be sucked away by the dust removal device, effectively preventing dust overflow. Specifically, the roller feeder consists of a motor, a reducer, a bearing housing, and a roller body. The motor operates at a variable frequency. An opening is left at the junction of the roller body and the hopper, and the roller body is eccentrically arranged. When the roller is not rotating, it ensures that the material will not fall. When the roller rotates, the material is carried out by the friction between the roller body and the material. Adjusting the motor frequency can change the roller rotation speed; the higher the rotation speed, the faster the feeding speed and the larger the feeding volume. For details not described in detail regarding the roller feeder, please refer to the prior art.

[0032] Preferably, the hopper 2 is welded from steel plates and has a material storage function, thereby ensuring a continuous and uninterrupted supply of materials.

[0033] The width of the feed pipe 4 is the same as the width of the screen plate 6. The material is controlled by the round roller to be evenly distributed on the screen plate 6 laterally through the feed pipe 4. The material does not need to be dispersed by the vibration of the screen body, which greatly improves the efficiency of the equipment.

[0034] Preferably, the air supply device includes an air box 21, an air inlet main pipe 9, a blower 12, and air inlet branch pipes 23. Multiple air boxes 21 are arranged below the vibrating screen, and the air boxes 21 are flexibly connected to the vibrating screen. The air inlet main pipe 9 is connected to the blower 12, and the air inlet main pipe 9 is connected to each air box 21 via air inlet branch pipes 23. Further, the air inlet main pipe 9 is equipped with a main pipe valve 11 and a main pipe detection element 10 for detecting the air pressure and velocity in the air inlet main pipe. The air inlet branch pipes 23 are equipped with branch pipe valves 25 and branch pipe detection elements 24 for detecting the air pressure and velocity in the air inlet branch pipes. An ash discharge valve 22 is provided at the bottom of the air box 21.

[0035] like Figure 1 and Figure 2 As shown in the figure, the flexible connection between the air box 21 and the vibrating screen is flexible connection 8. In this embodiment, multiple air boxes 21 are arranged along the length of the vibrating screen, and each air box can independently adjust the air volume and air pressure. This allows each air box to match the optimal air volume and air pressure according to the material type and the location of the air box. At the same time, the cooperation of the blower 12 and the main pipe detection component 10 ensures that the entire device can flexibly adjust the total air volume supplied by the blower according to different material types, thereby maximizing the screening efficiency and saving energy to the maximum extent.

[0036] Preferably, in this embodiment, the ash discharge valve 22 is a double-layer ash discharge valve. When the vibrating screen vibrates, a small amount of loose material will fall into the air box through the screen holes on the screen plate. Over time, this accumulation will affect the air intake of the air box. The double-layer ash discharge valve consists of upper and lower valve plates that open alternately to ensure no air leakage during material discharge. Furthermore, the double-layer ash discharge valve can be set to open at a certain time interval to discharge loose material. Alternatively, the weight or accumulated height of the loose material can be detected by a detection device. When a certain value is reached, the double-layer ash discharge valve will open to discharge the loose material.

[0037] Preferably, the vibrating screen has a discharge pipe 19 at its discharge end, one end of which is softly connected to the discharge end of the vibrating screen, and the other end is connected to a rotary valve 20. Figure 1 As shown in the figure, the flexible connection between the discharge pipe 19 and the vibrating screen is flexible connection 3 17. The rotary valve 20 has blades, which are driven by a motor to rotate and carry out the screened material.

[0038] Preferably, the flexible connection in this embodiment can be made of canvas, rubber or other flexible materials. The flexible connection separates the vibrating screening device from other non-vibrating components, minimizing the vibrating mass and saving motor energy. At the same time, the flexible connection can also achieve effective sealing between the components of the whole machine, preventing air leakage and dust overflow.

[0039] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
