Scrap iron vibrating screening device

Abstract

This utility model relates to the field of waste metal screening technology and discloses a vibrating screening device for scrap steel. It includes a fixed shell with a dispersing frame slidably connected to it. The material to be screened is crushed by a crusher and then conveyed to the dispersing frame by a conveyor belt. A protective component and a vibration component are installed on the fixed shell, and a screening component is located below the vibration component. A separation component is fixedly installed on the fixed shell. In this utility model, the accumulation of waste material in the dispersing frame can be monitored in real time through the contact switches one and two of the protective component in conjunction with a controller. When waste material accumulates, the dispersing frame descends under its own weight. When the compression support spring touches contact switch one, the controller automatically reduces the conveyor belt speed. If the accumulation decreases to the position of contact switch two, the normal conveying speed is restored, forming dynamic feeding control and avoiding a decrease in screening capacity due to excessive waste accumulation.

Description

Technical Field

[0001] This utility model relates to the field of waste metal screening, and in particular to a vibratory screening device for waste steel. Background Technology

[0002] Scrap metal recycling is a key link in resource recycling. Among them, scrap steel recycling is crucial. As the core equipment for scrap steel pretreatment, the vibrating screening device needs to separate scrap steel from impurities (such as soil) through vibration to provide raw materials with the required purity for subsequent smelting and processing.

[0003] Currently, in existing technologies, waste materials are typically crushed first using a crusher. The crushed waste is then conveyed by a conveyor belt to a screening device for vibrating screening to separate scrap steel from soil. This method is highly automated and reduces labor costs. However, during the waste screening process, if too much waste accumulates on the screen plate, the screening capacity decreases. The continuous conveyor belt transporting waste further increases the accumulation of waste on the screen plate, affecting the screening efficiency of scrap steel. Therefore, a scrap steel vibrating screening device is proposed to solve the above problems. Summary of the Invention

[0004] To overcome the above deficiencies, this utility model provides a scrap steel vibration screening device that can solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a scrap steel vibrating screening device, comprising a fixed shell, a dispersing frame slidably connected to the fixed shell, the screening material being crushed by a crusher and then conveyed to the dispersing frame by a conveyor belt, a protective component and a vibration component being provided on the fixed shell, a screening component being provided below the vibration component, and a separation component being fixedly installed on the fixed shell, the protective component comprising: Fixed block one, fixedly connected to the fixed shell, a contact switch one is fixedly installed on the upper side of fixed block one, and fixed block one is elastically connected to the dispersion frame through a support spring; A guide rod is fixedly connected to the upper side of a fixing block one. A fixing block two is fixedly connected to the top of the guide rod, and a contact switch two is fixedly installed on the lower side of the fixing block two.

[0006] As a further description of the above technical solution: The vibration assembly includes a fixed frame, which is fixedly connected to the outer wall of the fixed shell. A stepper motor is fixedly connected to the outer wall of the fixed frame, and a rotating shaft is fixedly connected to the output shaft of the stepper motor. The rotating shaft passes through an eccentric wheel and is fixedly connected to the eccentric wheel.

[0007] As a further description of the above technical solution: A fixing member is fixedly connected to the outer wall of the fixed shell. The fixing member is penetrated by the sleeve of the elastic telescopic rod and is slidably connected to the sleeve of the elastic telescopic rod. A striking block is fixedly connected to the telescopic part of the elastic telescopic rod, and a fixing ring is fixedly connected to the bottom of the elastic telescopic rod.

[0008] As a further description of the above technical solution: The fixing ring and the fixing member are elastically connected by a return spring. Under the elastic force of the return spring, the fixing ring abuts against the eccentric wheel.

[0009] As a further description of the above technical solution: The screening assembly includes a oscillating screen, which is rotatably connected to a fixed rod. A hinge rod is hinged to the outer wall of the oscillating screen, and the hinge rod is fixedly connected to a cam component. The cam component is fixed to the rotating rod.

[0010] As a further description of the above technical solution: Both the rotating shaft and the rotating rod are fixedly connected to transmission wheels, and the two sets of transmission wheels are connected by a transmission belt.

[0011] As a further description of the above technical solution: An opening is provided on the outer wall of the fixed shell, and an inclined plate is provided below the opening.

[0012] As a further description of the above technical solution: The separation assembly consists of a motor, a connecting shaft, and a rotating blade. The rotating blade is fixedly connected to the connecting shaft, and the connecting shaft is fixed to the output shaft of the motor.

[0013] As a further description of the above technical solution: The device also includes a controller, which is electrically connected to contact switch one and contact switch two, and the controller can control the conveying speed of the conveyor belt.

[0014] This utility model has the following beneficial effects: 1. In this utility model, the contact switch one and contact switch two of the protective component work together with the controller to monitor the accumulation of waste in the dispersion frame in real time. When the waste accumulates, the dispersion frame descends under the action of weight. When the compression support spring touches contact switch one, the controller automatically reduces the conveyor belt speed. If the accumulation amount is reduced to the position of contact switch two, the normal conveying speed is restored, forming dynamic feeding control, and avoiding the decrease in screening capacity caused by excessive accumulation of waste.

[0015] 2. In this utility model, the use of screening and separation components allows the waste dispersed by the dispersion frame to be blown by the wind to the inclined plate to discharge lighter soil, reducing the pressure on subsequent scrap steel screening. After the scrap steel falls into the oscillating screen, the rotating rod can drive the cam to rotate, which in turn drives the hinge rod to move, causing the oscillating screen to swing slightly around the fixed rod to screen the scrap steel, while also helping to remove the soil attached to the scrap steel.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figures 1-5The present invention provides an embodiment of a scrap steel vibration screening device, comprising a fixed shell 1, a dispersing frame 2 slidably connected to the fixed shell 1, the screening material being crushed by a crusher 4 and then conveyed to the dispersing frame 2 by a conveyor belt 3, a protective component 5 and a vibration component 6 being provided on the fixed shell 1, a screening component 7 being provided below the vibration component 6, and a separation component 8 being fixedly installed on the fixed shell 1, the waste material being crushed by the crusher 4 and falling onto the conveyor belt 3 for conveying, and then falling onto the dispersing frame 2 for dispersion, the dispersed waste material then being separated from scrap steel and soil by the screening component 7 and the separation component 8.

[0020] The protective component 5 includes a fixing block 51 and a guide rod 53. The fixing block 51 is fixedly connected to the fixing shell 1. A contact switch 52 is fixedly installed on the upper side of the fixing block 51. The fixing block 51 and the dispersion frame 2 are elastically connected by a support spring. The guide rod 53 is fixedly connected to the upper side of the fixing block 51. A fixing block 54 is fixedly connected to the top of the guide rod 53. A contact switch 55 is fixedly installed on the lower side of the fixing block 54. The device also includes a controller, which is electrically connected to the contact switch 52 and the contact switch 55. The controller can control the conveying speed of the conveyor belt 3, preventing the crushed material in the dispersion frame 2 from accumulating. At this time, the weight of the dispersing frame 2 is relatively light. Under the action of the support spring, the dispersing frame 2 abuts against the second contact switch 55, and the conveyor belt 3 maintains a normal conveying speed. When the crushed material in the dispersing frame 2 accumulates, the weight of the dispersing frame 2 increases, and the dispersing frame 2 descends under the action of weight. When the compression support spring touches the first contact switch 52, the controller automatically reduces the conveying speed of the conveyor belt 3. After that, the crushed material in the dispersing frame 2 gradually decreases. Under the action of the support spring, the dispersing frame 2 resets until it abuts against the second contact switch 55 again, and then the normal conveying speed is restored, forming dynamic feeding control to avoid the decrease in screening capacity caused by excessive accumulation of waste material.

[0021] Reference Figures 2-3The vibration assembly 6 includes a fixed frame 61, which is fixedly connected to the outer wall of the fixed housing 1. A stepper motor 62 is fixedly connected to the outer wall of the fixed frame 61. A rotating shaft 63 is fixedly connected to the output shaft of the stepper motor 62. The rotating shaft 63 passes through and is fixedly connected to the eccentric wheel 64. A fixing member 67 is fixedly connected to the outer wall of the fixed housing 1. The fixing member 67 is penetrated by the sleeve of the elastic telescopic rod 66 and is slidably connected to the sleeve of the elastic telescopic rod 66. A striking block 68 is fixedly connected to the telescopic part of the elastic telescopic rod 66. A bottom of the elastic telescopic rod 66 is fixedly connected to... The fixed ring 65 is elastically connected to the fixing member 67 through a return spring. Under the elastic force of the return spring, the fixed ring 65 abuts against the eccentric wheel 64. The output shaft of the stepper motor 62 rotates, driving the rotating shaft 63 to rotate, which in turn drives the eccentric wheel 64 to rotate. Under the action of the return spring, the elastic telescopic rod 66 can drive the striking block 68 to strike and vibrate the dispersion frame 2, accelerating the passage of crushed material in the dispersion frame 2. At the same time, under the action of the elastic telescopic rod 66, when the position of the dispersion frame 2 changes, the striking block 68 can still strike and vibrate the dispersion frame 2.

[0022] Reference Figure 2 The screening assembly 7 includes a oscillating screen 71, which is rotatably connected to a fixed rod 72. A hinge rod 73 is hinged to the outer wall of the oscillating screen 71, and the hinge rod 73 is fixedly connected to a cam 74. The cam 74 is fixed to a rotating rod 75. A transmission wheel is fixedly connected to both the rotating shaft 63 and the rotating rod 75, and the two sets of transmission wheels are connected by a transmission belt. When the rotating shaft 63 rotates, the rotating rod 75 rotates under the action of the transmission wheel and the transmission belt, which drives the cam 74 to rotate, and then drives the hinge rod 73 to move, so that the oscillating screen 71 swings slightly around the fixed rod 72 to screen the scrap steel, while also helping to remove the soil attached to the scrap steel.

[0023] Reference Figure 5 An opening is provided on the outer wall of the fixed shell 1, and an inclined plate 101 is provided below the opening. The separation component 8 consists of a motor, a connecting shaft and a rotating blade. The rotating blade is fixedly connected to the connecting shaft, and the connecting shaft is fixed to the output shaft of the motor. The rotating blade is driven by the motor to rotate, which can generate wind power. Under the action of wind power, the waste material dispersed by the dispersion frame 2 can blow the lighter soil onto the inclined plate 101 for discharge, reducing the pressure on the subsequent screening of scrap steel.

[0024] It should be noted that the above electrical components are all existing technology products. Those skilled in the art should select, install, and complete the circuit debugging work according to the needs of use to ensure that all electrical appliances can work normally.

[0025] Working principle: During use, waste material is crushed by crusher 4 and then falls onto conveyor belt 3 for conveying, and then falls into dispersing frame 2 for dispersion. During this process, when the crushed material in dispersing frame 2 is not piled up, the weight of dispersing frame 2 is relatively light. Under the action of the support spring, dispersing frame 2 abuts against contact switch 2 55, and conveyor belt 3 maintains normal conveying speed. When the crushed material in dispersing frame 2 piles up, the weight of dispersing frame 2 increases, and dispersing frame 2 descends under the action of weight. When the compression support spring touches contact switch 1 52, the controller automatically reduces the conveying speed of conveyor belt 3. After that, the crushed material in dispersing frame 2 gradually decreases. Under the action of the support spring, dispersing frame 2 resets until it abuts against contact switch 2 55 again, and then the normal conveying speed is restored. Simultaneously, the stepper motor 62 is started, and the output shaft of the stepper motor 62 rotates, driving the rotating shaft 63 to rotate, which in turn drives the eccentric wheel 64 to rotate. Under the action of the return spring, the elastic telescopic rod 66 can drive the striking block 68 to strike and vibrate the dispersion frame 2, accelerating the passage of crushed material in the dispersion frame 2. The motor is also started, and the motor drives the rotating blade to rotate, which can generate wind power. Under the action of the wind power, the passing crushed material can blow the lighter soil onto the inclined plate 101 for discharge. Finally, the waste falling onto the swing screen 71 is rotated by the rotating shaft 63. Under the action of the transmission wheel and the transmission belt, the rotating rod 75 rotates, driving the cam 74 to rotate, which in turn drives the hinge rod 73 to move, causing the swing screen 71 to swing slightly around the fixed rod 72 to screen the scrap steel.
