Description

Technical Field

[0001] This utility model relates to the field of used tire recycling and processing technology, specifically a device for removing carbon black from steel wires after tire oil refining. Background Technology

[0002] During the recycling of carbon black from waste tires, steel wires are separated by magnetic attraction, but some carbon black remains embedded in the initially separated wires. Steel wires containing carbon black are detrimental to recycling, and if they are remelted, the carbon black will negatively impact the entire process. Therefore, a more effective process for removing carbon black from steel wires is needed.

[0003] Utility model CN205799949U discloses a device for removing carbon black from steel wire in waste tires. The device includes a main body comprising a conveyor belt and a motor that drives the conveyor belt. The motor is located at the lower end of the conveyor belt, and a collection box is located at the end of the conveyor belt. A blower is mounted on the side of the conveyor belt, with its air outlet facing the surface of the conveyor belt. Multiple freely rotatable linear hubs are arranged along the lower part of the conveyor belt in the direction of its movement. In the traditional waste tire recycling process, after carbon black and steel wire are pre-separated by magnetic attraction, this utility model removes the small amount of carbon black still mixed in with the steel wire, thus enabling more complete recycling of the steel wire. This improves the quality and recovery rate of the recycled steel wire, solving the problem that a large amount of steel wire is recycled in the waste tire industry, but most of it is substandard.

[0004] However, the above-mentioned existing technology still has shortcomings in use: the air outlet of the induced draft fan is directly facing the surface of the conveyor belt. After the induced draft fan is started, the air outlet will suck away the carbon black in the steel wire. This setting can suck away some dust or light particles to a certain extent. However, for some carbon black particles that are attached to the steel wire or have a larger particle size, this direct suction method is difficult to remove this part of the carbon black. Therefore, there is a problem of incomplete removal of carbon black.

[0005] Therefore, this utility model provides a device for removing carbon black from steel wires after tire oil refining. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a device for removing carbon black from steel wire after tire oil refining, so as to solve the problems mentioned in the background technology. This utility model has the function of rolling steel wire to peel off carbon black and the function of inserting air suction to remove carbon black, so that the removal of carbon black is more thorough.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a device for removing carbon black from steel wire after tire pyrolysis, comprising a device body, an inclined conveyor belt and an induced draft fan located above the inclined conveyor belt on the device body, a lifting frame connected to the bottom of the induced draft fan, a wind duct rotatably connected to the bottom of the lifting frame, one end of the wind duct being connected to the air inlet of the induced draft fan through a pipeline, and uniformly distributed suction pipes fixedly connected to the outer periphery of the wind duct, with uniformly distributed suction holes opened on the outer peripheral wall of the suction pipes.

[0008] Furthermore, the lifting frame includes a guide sleeve and a rod with one end sleeved on the bottom of the guide sleeve. The top of the guide sleeve is fixedly connected to the bottom of the blower housing. One end of the air duct is fixedly connected to a transfer pipe that is rotatably connected to the bottom of the rod. One end of the transfer pipe is rotatably connected to a transfer sleeve.

[0009] Furthermore, a positioning sleeve is fixedly connected to the bottom of the boom and sleeved on the outside of the transfer pipe. A belt drive assembly is rotatably connected to the positioning sleeve. One end of the belt drive assembly is provided with a drive wheel whose bottom abuts against the upper surface of the conveyor belt on the inclined conveyor belt, and the other end is provided with a driven wheel that drives the air duct to rotate.

[0010] Furthermore, the belt drive assembly includes a connecting rod, one end of which is fixedly connected to a connecting sleeve one sleeved outside the positioning sleeve, and the other end of which is fixedly connected to a connecting sleeve two sleeved inside the driving wheel. The connecting sleeve two is rotatably connected to the driving wheel, and the driven wheel is fixedly sleeved on the adapter pipe. One side of both the driving wheel and the driven wheel is fixedly connected to a pulley connected by a transmission belt.

[0011] Furthermore, the outer diameters of the driving wheel and the driven wheel are equal, and the outer peripheral walls of both are fixedly fitted with drag-increasing rubber rings.

[0012] Furthermore, the suction tube is conical with the small end facing outwards.

[0013] Furthermore, a vibration motor is installed on one side of the boom.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. In this utility model, a lifting frame is set up, and a fan duct is installed at the bottom of the lifting frame. The fan duct is set up to be rotatably connected to the lifting frame, so that when the inclined conveyor belt is transporting steel wires, the steel wires will be deformed by the weight of the fan duct. The carbon black attached to the steel wires will fall off after being squeezed. By setting evenly distributed suction pipes on the outer periphery of the fan duct, the suction pipes will be inserted into the gaps formed by the curling of the steel wires during the rotation of the fan duct, so as to reliably suck away carbon black dust and particulate matter, which has the advantage of more thorough carbon black removal.

[0016] 2. In this utility model, a belt drive assembly is provided between the conveyor belt and the air duct. This belt drive assembly enables the conveyor belt to drive the air duct to rotate when it is running, so that the air duct can roll reliably, avoiding the problem of the air duct pushing the material, and making the air duct rolling and air suction of the steel wire more reliable.

[0022] 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 in conjunction with specific embodiments.

[0023] Please see Figures 1 to 4 This utility model provides a technical solution: a device for removing carbon black from steel wire after tire pyrolysis, comprising a device body 1, an inclined conveyor belt 11 and an induced draft fan 12 located above the inclined conveyor belt 11, a housing and an air inlet located below the housing on the induced draft fan 12, an air outlet pipe on the top of the housing, and the air outlet pipe being connected to an external carbon black filtration system through a pipeline. This carbon black filtration system is prior art and will not be described in detail in this application.

[0024] In this technical solution, a lifting frame 2 is connected to the bottom of the induced draft fan 12, and a duct 3 is rotatably connected to the bottom of the lifting frame 2. Preferably, the lifting frame 2 includes a guide sleeve 21 and a hanging rod 22 with one end sleeved on the bottom of the guide sleeve 21. The top of the guide sleeve 21 is fixedly connected to the bottom of the casing of the induced draft fan 12, and one end of the duct 3 is fixedly connected to a transfer pipe 31 that is rotatably connected to the bottom of the hanging rod 22. The bottom of the duct 3 will abut against the upper surface of the conveyor belt 111 on the inclined conveyor belt 11 due to its own weight. In use, a steel wire with carbon black is placed on the conveyor belt 111. When the steel wire passes through the duct 3, the duct 3 will roll the steel wire, and the rolling process will easily peel off the carbon black particles attached to the steel wire.

[0025] Furthermore, one end of the duct 3 is connected to the air inlet of the induced draft fan 12 via a pipeline. Preferably, one end of the adapter pipe 31 is rotatably connected to an adapter sleeve 5. During use, the adapter sleeve 5 is fixedly connected to one side of the connecting rod and the hanger 22. The adapter sleeve 5 and the adapter pipe 31 employ a common rotating sealing fit structure. Then, the air outlet of the adapter sleeve 5 is connected to the air inlet of the induced draft fan 12 via a pipeline. The pipeline here is a corrugated flexible hose. Evenly distributed suction pipes 4 are fixedly connected to the outer periphery of the duct 3. When the duct 3 passes over the steel wire, the suction pipes 4 and the outer wall of the duct 3 compress the steel wire (which is in a bent and deformed state). The suction pipes 4 insert into the gaps formed by the steel wire. Evenly distributed suction holes 41 are opened on the outer wall of the suction pipes 4. After the induced draft fan 12 is started, the suction holes 41 generate suction, which reliably removes the carbon black from the steel wire, thereby greatly improving the efficiency of carbon black cleaning and making the cleaning more thorough.

[0026] In this embodiment, a positioning sleeve 221 is fixedly connected to the bottom of the boom 22 and sleeved on the outside of the adapter pipe 31. A belt drive assembly 6 is rotatably connected to the positioning sleeve 221. One end of the belt drive assembly 6 is provided with a drive wheel 61 whose bottom abuts against the upper surface of the conveyor belt 111 on the inclined conveyor belt 11, and the other end is provided with a driven wheel 62 that drives the air duct 3 to rotate. In use, the drive wheel 61 contacts the position on one side of the conveyor belt 111. That is to say, during the operation of the conveyor belt 111, the drive wheel 61 will be driven to rotate by friction, and then the air duct 3 will be driven to rotate through the driven wheel 62. This arrangement makes the rotation of the air duct 3 more reliable and avoids the problem of the air duct 3 being pushed by the accumulation of steel wire, which affects the removal of carbon black.

[0027] Specifically, the belt drive assembly 6 includes a connecting rod 63. One end of the connecting rod 63 is fixedly connected to a connecting sleeve 631 that is sleeved outside the positioning sleeve 221, and the other end is fixedly connected to a connecting sleeve 632 that is sleeved inside the driving wheel 61. The connecting sleeve 631 and the positioning sleeve 221 are rotatably connected, and the connecting sleeve 632 and the driving wheel 61 are rotatably connected. The driven wheel 62 is fixedly sleeved on the adapter pipe 31. One side of both the driving wheel 61 and the driven wheel 62 is fixedly connected to a pulley 65 that is connected by a transmission belt 64. Thus, when the driving wheel 61 rotates, it will drive the driven wheel 62 to rotate through the transmission belt 64.

[0028] Furthermore, the outer diameters of the driving wheel 61 and the driven wheel 62 are equal, and the outer peripheral walls of both are fixedly fitted with a friction-increasing rubber ring 7. This arrangement makes the rotation speeds of the driving wheel 61 and the driven wheel 62 consistent. The outer diameter of the driven wheel 62 and the outer diameter of the air duct 3 are approximately equal. Alternatively, the outer diameter of the driven wheel 62 can be set to be larger or smaller than that of the air duct 3 as needed.

[0029] Among them, the suction tube 4 is conical with the small end facing outward. This design can prevent material from getting stuck in the suction tube 4. In other words, the conical structure of the suction tube 4 makes it less likely to get tangled with steel wire.

[0030] In addition, a vibration motor 9 is installed on one side of the boom 22. When the vibration motor 9 is started, it will transmit vibration to the air duct 3 through the boom 22. The vibration can accelerate the separation of carbon black on the steel wire. When in use, the vibration motor 9 is electrically connected to the control box of this device.

[0031] Working principle: During use, the steel wire that has been magnetically treated by oil refining is placed on the inclined conveyor belt 11. The inclined conveyor belt 11 rotates and moves the steel wire on it towards the air duct 3. At the same time, the induced draft fan 12 is started, and the conveyor belt 111 drives the drive wheel 61 to rotate, which in turn drives the driven wheel 62 to rotate. At this time, the air duct 3 rotates. When the steel wire passes through the air duct 3, the air duct 3 will roll the steel wire. At the same time, the hanger 22 will adaptively move up and down along the guide sleeve 21. The carbon black on the steel wire falls off. The suction pipe 4 is located in the gap of the steel wire and sucks away the carbon black dust and particles, thereby realizing the function of efficient cleaning of carbon black by this device.

[0032] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
