Description

TECHNICAL FIELD

[0002] Copper waste includes copper wire and scrap copper block etc., copper wire is due to storage transportation or some operations in the process of collection and causes mutual entanglement, so that copper wire is broken before processing, so that the copper wire that is entangled into a ball is separated from each other and broken into small sections, and the copper block of large structure or the copper-containing waste of large volume cannot be broken by the processing device of metal wire rod. Different sizes of copper waste are mixed with each other, and the copper waste needs to be put into a melting furnace for melting and mixing recovery when recycling. If the volume difference of copper waste is too large, the melting progress of different copper waste will be different, which affects the recovery efficiency of copper waste. Therefore, the copper waste needs to be screened before processing, so that copper waste of different volumes is classified and collected, so that the large-volume copper waste can be broken and reprocessed.

However, in order to separate large-volume copper waste from the waste pile, a large-aperture screening structure needs to be set at a higher position in the prior art. There are certain safety hazards when large-volume copper waste is discharged: if the collection structure is set at a higher position, the collection structure is heavy after being filled, and the risk of overturning or falling and bruising will occur when the collection structure is removed by the worker; if the collection structure is set at a low position, the large-volume copper waste will hit the side wall or bottom of the collection structure when it falls out of the discharge port, thereby causing damage to the collection structure.

[0025] 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.

[0026] Example 1

[0027] A copper scrap screening device, such as Figures 1-4 As shown, it includes an outer shell 1; the outer shell 1 is equipped with a screening mechanism 2, which can screen copper scrap and separate copper scrap of different sizes, thereby facilitating the subsequent individual processing of copper scrap of different sizes and improving the processing efficiency of copper scrap.

[0028] Specifically, the screening mechanism 2 includes a support column 21 connected to the middle of the interior of the outer shell 1. The support column 21 supports the screening mechanism 2 and can oscillate up and down inside the outer shell 1, thereby agitating the copper scrap on the screening mechanism 2. This oscillation helps to separate stacked copper scrap, facilitating the screening operation. A screen plate 22 is fixedly connected to the outside of the support column 21. The screen plate 22 has screening openings 23, through which the copper scrap can be screened. A baffle 24 is rotatably connected to the screen plate 22. The baffle 24 divides the interior space of the outer shell 1 into several spaces, allowing for individual screening of the copper scrap within each space.

[0029] It is worth mentioning that two sieve plates 22 are provided, and the two sieve plates 22 are arranged in parallel on the side of the support column 21, the aperture of the screening port 23 is sequentially reduced, the size of the screening port 23 on the sieve plate 22 is sequentially increased or reduced clockwise or counterclockwise, the screening ports 23 of the upper sieve plate 22 are in a sealing plate structure, which can block and separate the copper waste, and the screening ports 23 of the lower sieve plate 22 are in a through hole structure, which can allow the copper waste to directly pass through the discharge. In this embodiment, the screening ports 23 on the upper sieve plate 22 are in a sealing plate, a medium aperture screening port 23, a small aperture screening port 23, and a through hole in sequence, and the corresponding positions of the screening ports 23 of the lower sieve plate 22 are in a medium aperture screening port 23, a small aperture screening port 23, and a through hole in sequence.

[0030] Further, the inside bottom end of the support column 21 is fixedly connected with an oscillation spring 25, the oscillation spring 25 can oscillate the support column 21, so that the support column 21 and the sieve plate 22 are irregularly shaken, and the vibration screening of the copper waste is realized. The bottom end of the oscillation spring 25 is rotatably connected with an oscillation seat 26, and the top end of the oscillation seat 26 and the bottom end of the support column 21 are fixedly connected with an arc-shaped protrusion 27. The structure of the oscillation seat 26 can drive the support column 21 through the arc-shaped protrusion 27.

[0031] Embodiment 2

[0032] As shown in Figures 1-4 On the basis of embodiment 1, the inside of the shell 1 is provided with a switching mechanism 5, the switching mechanism 5 can drive the baffle 24 to rotate, so that the copper waste raw material is moved and switched, and the copper waste can be screened through different screening ports 23.

[0033] In this embodiment, the top end of the shell 1 is fixedly connected with a feeding hopper 3, and the structure of the feeding hopper 3 can facilitate the feeding of the copper waste raw material. The bottom end of the shell 1 is provided with a discharge port 4, which can facilitate the discharge of the screened copper waste.

[0034] On this basis, the switching mechanism 5 includes a support ring 51 slidably connected outside the baffle 24, and the inner wall of the shell 1 is provided with a support groove 52 corresponding to the structure of the support ring 51. The structure of the support ring 51 can be matched with the support groove 52 and support and limit the baffle 24 and the support column 21, so as to avoid the inclination and deviation of the support column 21. At the same time, the sliding connection of the baffle 24 can facilitate the up-and-down oscillation of the baffle 24 when the baffle 24 is driven.

[0035] It is worth mentioning that the inside bottom end of the shell 1 is rotatably connected with a drive gear 53, the drive gear 53 is a cogwheel structure, the bottom end of the shell 1 is fixedly connected with a motor 54, the output shaft of the motor 54 passes through the shell 1 and is arranged, the output shaft of the motor 54 is fixedly connected with the drive gear 53, and the structure of the motor 54 can drive the drive gear 53 to rotate continuously.

[0036] Further, the bottom end of the baffle plate 24 is fixedly connected with a driving frame 55, the inner side of the driving frame 55 is fixedly connected with a gear ring 56 which is engaged with the driving gear 53, the baffle plate 24 is matched with the driving gear 53 through the engaged gear ring 56, so that the baffle plate 24 can rotate continuously, meanwhile, the driving gear 53 is a gear structure with residual teeth, so that the driving gear 53 can reduce the rotating speed of the gear ring 56 when driving the gear ring 56, thereby improving the screening effect of the copper waste.

[0037] The copper waste screening device of the utility model in use, first of all, the copper waste raw materials are put into the device from the feed inlet, and the copper waste is divided into four parts by the baffle plate 24. Then the motor 54 starts and drives the driving gear 53 to rotate continuously. The driving gear 53 drives the oscillating seat 26 to rotate through the engaged transmission gear 57 during rotation. Because the driving gear 53 is a gear structure with residual teeth, the transmission gear 57 rotates a certain angle at a time when driven. During the rotation of the transmission gear 57, the arc-shaped protrusions 27 at the top of the oscillating seat 26 rotate from the gap between the arc-shaped protrusions 27 at the bottom of the support column 21 to the abutment of the arc-shaped protrusions 27 on the oscillating seat 26 and the arc-shaped protrusions 27 on the support column 21. The support column 21 is driven to move upward, and then the abutted arc-shaped protrusions 27 rotate again to be misaligned. After rotating misaligned, the driving gear 53 rotates to disengage from the transmission gear 57. After being driven to move upward, the support column 21 elongates the oscillating spring 25, and when falling subsequently, the support column 21 is driven by the elongated oscillating spring 25 to oscillate, so that the support column 21 and the screen plate 22 continuously oscillate the copper waste. During screening, the large-diameter screening holes on the upper screen plate 22 can pass all sizes of copper waste raw materials, and the small-diameter screening holes on the lower layer screen plate 22 can screen the copper waste raw materials, so that small copper waste raw materials pass through the discharge port for collection, and large copper waste raw materials stay on the lower screen plate 22.

[0038] When the copper waste raw materials fall to the middle screen hole of the upper screen plate 22, the screen plate 22 screens the copper waste raw materials, so that the medium-sized raw materials fall through the screen plate 22 to the lower screen plate 22, and are screened again by the small-diameter screening holes on the lower screen plate 22.

[0039] When the copper waste raw materials fall to the small-diameter screening holes of the upper screen plate 22, the small-size copper waste raw materials fall through the screening holes and move to the discharge port through the through holes of the lower screen plate 22 for collection.

[0040] In the process of driving gear 53 rotation, the tooth ring 56 is driven, the baffle 24 is rotated and the copper scrap raw material is driven, the raw material of the upper sieve plate 22 rotates along the direction of the sealing plate, the sealing plate, the medium aperture, the large aperture and the sealing plate. The raw material on the medium aperture falls from the upper sieve plate 22 to the lower sieve plate 22 when rotating to the large aperture screening hole, and is screened again through the small aperture screening hole of the lower sieve plate 22. The raw material of the lower sieve plate 22 rotates in the direction of the medium aperture, the through hole, the small aperture, the small aperture and the medium aperture. When the copper scrap raw material rotates from the small aperture of the lower sieve plate 22 to the medium aperture, the corresponding position of the upper sieve plate 22 is the sealing plate, so no new copper scrap raw material will fall, and the medium aperture sieve plate 22 is screened by the previous small aperture sieve plate 22, only the medium volume and large volume copper scrap raw material is left. The screening hole of the medium aperture can screen the medium volume and large volume copper scrap raw material, separate the medium volume from the large volume, and after subsequent rotation, the large volume copper scrap raw material is discharged from the through hole.
