A steel wire magnetic separation device for waste tire processing

Abstract

This utility model relates to the field of magnetic separation device technology, and in particular to a steel wire magnetic separation device for waste tire processing. It includes a working box, the interior of which is divided into a first working chamber and a second working chamber by a partition. The second working chamber contains at least two sets of vertically arranged magnetic rollers, driven to rotate by a rotating assembly. The first working chamber has a hinged first screening component with its output end located within the second working chamber. This utility model uses the first screening component to pre-screen the residue after pyrolysis, removing most of the carbon black. The screened steel wire and some carbon black residue then fall into the second working chamber, where the magnetic rollers attract the steel wire. After a scraping component removes the steel wire attracted by the magnetic rollers, it falls onto the second screening component for further screening, shaking off and removing the carbon black from the magnetically separated steel wire, thus improving the quality of the magnetically separated steel wire.

Description

Technical Field

[0001] This utility model relates to the field of magnetic separation device technology, and in particular to a steel wire magnetic separation device for waste tire processing. Background Technology

[0002] Tires contain steel wires (mainly high-strength steel wires in the bead section, used to fix the shape of the tire). During the pyrolysis recycling process, the steel wires need to be separated from components such as rubber and carbon black for separate recycling. This can also improve the purity of the carbon black. Magnetic separation is a common method to achieve this separation.

[0003] However, during magnetic separation and screening, carbon black residue is usually directly adsorbed by a magnet. Some carbon black will adhere to the steel wire residue. The carbon black adhering to the steel wire will enter the metal recycling process along with the steel wire, and will eventually be burned or discarded during the steel wire smelting or processing, resulting in the waste of carbon black.

[0004] Based on the above situation, we propose a steel wire magnetic separation device for waste tire processing to solve the above problems. Utility Model Content

[0005] This invention provides a magnetic separation device for steel wire in waste tire processing, which solves the problem of carbon black being wasted when steel wire is screened and carried along with it.

[0006] The technical problem solved by this utility model is achieved by the following technical solution:

[0007] A magnetic separation device for steel wire in waste tire processing includes a working box. The interior of the working box is divided into a first working chamber and a second working chamber by a partition. The second working chamber is equipped with at least two sets of magnetic rollers arranged vertically, and the two sets of magnetic rollers are driven to rotate by a rotating assembly. The first working chamber is hinged to a first screening component with its output end located in the second working chamber, which is used to perform preliminary screening of carbon black residue fed into the working box. The second working chamber is also equipped with a scraper component that contacts the magnetic rollers, which is used to scrape off the steel wires adsorbed on the magnetic rollers. Below the magnetic rollers is a second screening component that is hinged to the second working chamber, which is used to further screen the carbon black residue remaining in the steel wires scraped off by the scraper component. Both the first screening component and the second screening component are connected to the rotating assembly through a first belt drive mechanism to achieve vibratory screening of the first screening component and the second screening component.

[0008] Preferably, the interior of the second working chamber is provided with an intercepting plate, and the intercepting plate and the scraper are arranged to form a feeding channel facing the second screening component.

[0009] Preferably, the rotating assembly includes a drive motor mounted on the working box and a rotating shaft connected to the magnetic roller. Two adjacent rotating shafts are connected by a second belt drive mechanism, and the output end of the drive motor is connected to one of the rotating shafts.

[0010] Preferably, both the first working chamber and the second working chamber are rotatably connected to rotating rods. The two rotating rods are located below the first screening component and the second screening component, respectively, and are fitted with eccentric wheels. The two rotating rods are connected to one of the rotating shafts through a first belt drive mechanism.

[0011] Preferably, the interior of the second working chamber is provided with a baffle plate, and the baffle plate is in contact with the magnetic roller located at the top.

[0012] Preferably, a first guide plate connected to the second working chamber is provided below the magnetic suction roller located at the bottom, and a second guide plate connected to the second working chamber is provided below the second screening component, and both the first guide plate and the second guide plate extend into the first working chamber and are inclined downwards towards the first working chamber.

[0013] Preferably, the partition is provided with a flow-deflecting element, which is located between two adjacent magnetic rollers.

[0014] The beneficial effects of this utility model are as follows: the residue after pyrolysis is pre-screened by the first screening component, and most of the carbon black mixed in is screened. After that, the screened steel wire and some carbon black residue fall into the second working chamber, where the steel wire is attracted by the magnetic roller. When the scraper scrapes the steel wire attracted by the magnetic roller, it falls onto the second screening component for screening again, and the carbon black on the magnetically separated steel wire is shaken off and screened again, thereby improving the quality of the steel wire after magnetic separation.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below with reference to specific illustrations.

[0021] Reference Figures 1-3 As shown, a magnetic separation device for steel wire in waste tire processing includes a working box 1. The working box 1 is divided into a first working chamber 12 and a second working chamber 13 by a partition 11. The first working chamber 12 can be provided with a feed inlet for feeding pyrolysis residue. At least two sets of magnetic rollers 2 arranged vertically are provided inside the second working chamber 13. Neodymium iron boron permanent magnets can be installed on the surface of the magnetic rollers 2 to achieve a magnetic attraction effect. The two sets of magnetic rollers 2 are driven to rotate by a rotating assembly. An output is hinged inside the first working chamber 12. The first screening component 3, located inside the second working chamber 13, is inclined downwards towards the magnetic roller 2. It is used for preliminary screening of the carbon black residue fed into the working chamber 1, reducing the amount of carbon black during subsequent magnetic adsorption. After screening, a portion of the carbon black falls into the first working chamber 12, while the remaining steel wire and residue fall into the second working chamber 13 along with the downward movement of the first screening component 3. The steel wire is then adsorbed by the magnetic roller 2. Inside the second working chamber 13, a scraper component 4 is also provided that contacts the magnetic roller 2. Figure 3 As shown, taking the clockwise rotation of the magnetic roller 2 as an example, after the magnetic roller 2 adsorbs the steel wire, when it rotates to the point of contact with the scraper 4, the scraper 4 scrapes off the attached steel wire without affecting the subsequent adsorption of the steel wire. Furthermore, a second screening component 5 is provided below the magnetic roller 2 and is hinged to the second working chamber 13. The scraped steel wire can fall onto the second screening component 5. The second screening component 5 can be provided in a set, that is, below the lowest magnetic roller 2, so that the steel wire scraped off from each magnetic roller 2 can fall onto the second screening component 5, and the carbon black attached to the steel wire after magnetic adsorption can be screened again, reducing the amount of carbon black attached to the steel wire after magnetic separation and improving the quality of steel wire magnetic separation. The second screening component 5 can extend to the outside of the working chamber 1 and be set at an angle downward to facilitate the falling of the steel wire, and guide the screened steel wire to the outside of the working chamber 1 for unified collection.

[0022] Reference Figure 3 As shown, the second working chamber 13 is further provided with an intercepting plate 14. The intercepting plate 14 and the scraper 4 form a feeding channel 15 facing the second screening member 5, so that the scraper 4 can guide the steel wire scraped off the magnetic roller 2 through the feeding channel 15 to the top of the second screening plate, so as to avoid the steel wire falling randomly when scraping it off.

[0023] Reference Figure 1-3 As shown, the rotating assembly further includes a drive motor 7 mounted on the working housing 1 and a rotating shaft 71 connected to the magnetic roller 2. Two adjacent rotating shafts 71 are connected by a second belt transmission mechanism 8, and the output end of the drive motor 7 is connected to one of the rotating shafts 71. When the drive motor 7 drives one of the rotating shafts 71 to rotate, it drives the other rotating shaft 71 to rotate through the second belt transmission assembly, thereby driving the magnetic roller 2 and causing the magnetic roller to attract steel wires when it reciprocates.

[0024] Reference Figures 1-3 As shown, both the first working chamber 12 and the second working chamber 13 are rotatably connected to rotating rods 9. The two rotating rods 9 are located below the first screening component 3 and the second screening component 5, respectively, and are fitted with eccentric wheels 91. The two rotating rods 9 are connected to one of the rotating shafts 71 through the first belt drive mechanism 6. When the rotating shaft 71 rotates, it will drive the two rotating rods 9 to rotate synchronously through the first belt drive mechanism 6. The working box 1 at the higher end of the first screening component 3 and the second screening component 5 is hinged. When the rotating rods 9 drive the eccentric wheels 91 to rotate, they will continuously strike the first screening component 3 and the second screening component 5 from below, causing them to shake and perform screening work. Furthermore, the mesh size on the first screening component 3 and the second screening component 5 is small, which is sufficient to allow carbon black powder to pass through.

[0025] Both the first belt drive mechanism 6 and the second belt drive mechanism 8 can be composed of pulleys and drive belts sleeved on the corresponding pulleys to achieve synchronous movement.

[0026] Reference Figure 3 As shown, the second working chamber 13 is further provided with a baffle plate 16 inside, and the baffle plate 16 is in contact with the magnetic roller 2 located at the top to intercept the steel wire falling from the first screening piece 3, so that it falls through the gap between the magnetic roller 2 and the baffle plate 11. The distance between the baffle plate 11 and the magnetic roller 2 should not be too large to ensure that the falling steel wire can fall on one side of the magnetic roller 2 for magnetic adsorption.

[0027] Among them, a baffle 19 is provided on the partition 11. The baffle 19 is located between two adjacent magnetic rollers 2. When the material falls after passing the upper magnetic roller 2, the state of the falling material is changed by the baffle 19. The steel wires that are not attracted by the upper magnetic roller 2 will change direction under the baffle and become relatively dispersed, so that the lower magnetic roller 2 can attract the upper magnetic roller 2 that has not been attracted again.

[0028] Reference Figure 3 As shown, further, a first guide plate 17 connected to the second working chamber 13 is provided below the magnetic suction roller 2 at the bottom, and a second guide plate 18 connected to the second working chamber 13 is provided below the second screening component 5. Both the first guide plate 17 and the second guide plate 18 extend into the first working chamber 12 and are inclined downwards into the first working chamber 12. The carbon black after being attracted by the steel wire by the magnetic suction roller 2 will enter the first working chamber 12 through the first guide plate 17. Some carbon black will fall off the material after being vibrated and screened on the second screening component 5 and will also fall onto the second guide plate 18 and enter the first working chamber 12, so as to collect the carbon black in a concentrated manner.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
