Description

Technical Field

[0001] This utility model belongs to the field of construction waste technology, specifically a magnetic separation vibrating screen device for construction waste. Background Technology

[0002] In construction waste, inorganic aggregates such as concrete and bricks account for about 70%, metal impurities such as steel bars and wires account for 3%-8%, and the remainder consists of glass, plastics, etc.

[0003] Unsorted construction waste is directly landfilled or simply crushed, resulting in the loss of recyclable metals. The recycled aggregate has a high impurity content, making it difficult to meet building material standards. Manual sorting is inefficient, and the metal recovery rate is less than 70%. A large number of sharp objects such as iron nails and steel bar ends are mixed into the aggregate, affecting the quality of recycled products.

[0004] Therefore, this utility model provides a magnetic separation vibrating screen device for construction waste. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve at least one of the problems mentioned in the background technology, a magnetic separation vibrating screen device for construction waste is proposed.

When the vibrating motor starts, the construction waste generates a large amount of dust due to the intense vibration, and the barrier plate can seal the box in time through the torsion spring as the construction waste enters the box, preventing dust leakage.

[0007] Preferably, the support assembly includes a fixed long plate and ball bearings. Two sets of fixed long plates are provided, and the two sets of fixed long plates are staggered and fixedly installed on the top and bottom of the inner wall of the box. The inner wall of the fixed long plate and the ball bearings are rotatably installed. In this solution, the cooperation between the fixed long plate and the ball bearings can provide stable support for the collection box. At the same time, the ball bearings make it easier and less strenuous to pull out the collection box.

[0008] Preferably, the screening mechanism includes a baffle, a collection box, a screen, and a first handle. The baffle is fixedly installed on the top of the box near the feed inlet. The collection box is slidably installed on the top of the two sets of fixed long plates. The collection box is slidably installed with the box body. The top of the collection box is movably installed with the screen. The side of the collection box away from the box body is fixedly installed with the first handle. In this scheme, the combined use of the baffle, collection box, screen, and first handle can perform multi-stage screening of construction waste, classify construction waste into different sizes and types, and improve the efficiency of reuse.

[0009] Preferably, the magnetic attraction mechanism includes a sealing plate, a magnet, and a second handle. The sealing plate is slidably installed on the bottom of one side of the box. The side of the sealing plate away from the box is fixedly installed with the second handle, and the side of the sealing plate away from the second handle is fixedly installed with the magnet. In this solution, the combined use of the sealing plate, the magnet, and the second handle can attract iron elements in the construction waste, preventing iron items from being mixed in the construction waste, thus avoiding resource waste and affecting the reuse of waste.

[0010] Preferably, the feeding mechanism includes an extension plate, a conveyor belt, and a drive motor. The extension plate is fixedly installed on the side of the box away from the sealing plate. The inner wall of the extension plate is rotatably installed with the conveyor belt, and the conveyor belt is rotatably installed with the box. The drive motor is fixedly installed on one side of the extension plate, and the output end of the drive motor is fixedly installed with the conveyor belt. In this scheme, the combined use of the extension plate, the conveyor belt, and the drive motor can transport unscreenable construction waste to the outside of the box, so that users can process the waste.

[0011] Preferably, the vibrating motor is fixedly installed on the side of the box near the extension plate. In this scheme, the vibrating motor can make the screen screening more efficient by generating vibration, and at the same time, it can also increase the falling speed of construction waste to achieve the function of rapid screening.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. The construction waste magnetic separation vibrating screen device of this utility model, through the setting of the shaft frame and the baffle plate, can ensure that the construction waste can pass through smoothly while providing a sealing effect for the box. When the vibrating motor starts, the construction waste will generate a lot of dust due to the violent vibration. The torsion spring can seal the box in time as the construction waste enters the box to prevent the dust from leaking out.

[0014] 2. The construction waste magnetic separation vibrating screen device of this utility model, through the setting of fixed long plate and ball bearings, enables the fixed long plate and ball bearings to provide stable support for the collection box. At the same time, the setting of ball bearings makes the collection box easier and less labor-intensive to pull out. Attached Figure Description

[0024] Specific implementation examples are given below.

[0025] like Figures 1 to 5As shown in the embodiment of this utility model, a construction waste magnetic separation vibrating screen device includes a housing 1 and a vibrating motor 90; a feed inlet 2 is fixedly installed on the top of the housing 1, a support leg 3 is fixedly installed on the bottom of the housing 1, a blocking component 4 is provided on the top of the housing 1 near the feed inlet 2, and a support component 5 is provided on the inner wall of the housing 1; a screening mechanism 6 is provided on the top of the fixed long plate 51, a magnetic attraction mechanism 7 is provided on one side of the housing 1; a feeding mechanism 8 is provided on the side of the housing 1 away from the magnetic attraction mechanism 7; the blocking component 4 includes a shaft frame 41 and The baffle plate 42 and the shaft bracket 41 are fixedly installed on both sides of the top of the box 1 near the feed inlet 2. The inner wall of the shaft bracket 41 is rotatably installed with the baffle plate 42. The shaft bracket 41 has a torsion spring inside, which is used to keep the baffle plate 42 in a closed state. The support assembly 5 includes a fixed long plate 51 and a ball bearing 52. Two sets of fixed long plates 51 are provided. The two sets of fixed long plates 51 are fixedly installed in an alternating manner on the top and bottom of the inner wall of the box 1. The inner wall of the fixed long plate 51 is rotatably installed with the ball bearing 52. The screening mechanism 6 includes a baffle plate 61, a collection box 62, and a screen 63. The first handle 64 and the baffle 61 are fixedly installed on the top of the box 1 near the feed inlet 2. The collection box 62 is slidably installed on the top of the two sets of fixed long plates 51. The collection box 62 is slidably installed with the box 1. The top of the collection box 62 is movably installed with the screen 63. The side of the collection box 62 away from the box 1 is fixedly installed with the first handle 64. The magnetic attraction mechanism 7 includes a sealing plate 71, a magnet 72 and a second handle 73. The sealing plate 71 is slidably installed on the bottom of one side of the box 1. The side of the sealing plate 71 away from the box 1 is fixedly installed with the second handle 73. The sealing plate 71 is fixedly installed with the magnet 72 on the side away from the second handle 73. The feeding mechanism 8 includes an extension plate 81, a conveyor belt 82 and a drive motor 83. The extension plate 81 is fixedly installed on the side of the box 1 away from the sealing plate 71. The inner wall of the extension plate 81 is rotatably installed with the conveyor belt 82. The conveyor belt 82 is rotatably installed with the box 1. The drive motor 83 is fixedly installed on one side of the extension plate 81. The output end of the drive motor 83 is fixedly installed with the conveyor belt 82. The side of the box 1 near the extension plate 81 is fixedly installed with the vibration motor 90.

[0026] like Figures 1 to 5As shown, the cooperation between the shaft bracket 41 and the baffle plate 42 ensures that construction waste can pass through smoothly while also providing a sealing effect for the box 1. When the vibrating motor 90 starts, the construction waste will generate a large amount of dust due to the intense vibration. The baffle plate 42 can seal the box 1 in time with the torsion spring as the construction waste enters the box 1, preventing dust leakage. The cooperation between the fixed long plate 51 and the ball bearing 52 can provide stable support for the collection box 62. At the same time, the ball bearing 52 makes it easier and less strenuous to pull out the collection box 62. The cooperation between the baffle plate 61, the collection box 62, the screen 63 and the first handle 64 can effectively manage construction waste. The material undergoes multi-stage screening, which can classify construction waste into different sizes and types, improving the efficiency of reuse. The combined use of sealing plate 71, magnet 72, and second handle 73 can adsorb iron elements in construction waste, preventing iron items from being mixed in with the construction waste, thus avoiding resource waste and affecting waste reuse. The combined use of extension plate 81, conveyor belt 82, and drive motor 83 can transport unscreenable construction waste to the outside of the box 1 for user processing. Vibration motor 90 generates vibration, which can make the screen 63 more efficient in screening and also increase the falling speed of construction waste to achieve rapid screening.

[0027] Working principle: During operation, the box 1 is first placed on a flat surface. Then, the user pours construction waste into the inlet 2. The construction waste will move towards the baffle plate 42 through the tilt of the inlet 2. The baffle plate 42 will then be pushed open by the construction waste, which will fall onto the top screen 63. At the same time, the user starts the vibration motor 90 to make it vibrate. The vibration motor 90 will transmit the vibration through the box 1 to the screen 63. After receiving the vibration, the construction waste on the top of the screen 63 will move downward due to the vibration. Meanwhile, the waste screened by the composite screening will enter the collection box 6. Inside 2, as the top and bottom screens 63 continuously screen, the construction waste can be divided into two groups of different sizes. Construction waste that cannot be screened, such as larger stones, nails, and steel bars, will fall through the bottom screen 63 onto the top of the conveyor belt 82. When the construction waste falls, the metal objects contained inside will be attracted by the magnet 72. The construction waste will then be transported to the outside of the box 1 by the conveyor belt 82. When the user uses the conveyor belt 82, he / she only needs to start the drive motor 83. At the same time, the user can pull out the collection box 62 and the sealing plate 71 through the first handle 64 and the second handle 73 respectively.
