Description
Technical field
The utility model relates to reactor manufacturing technology field, especially a kind of feeding unit that carries out the cracking still use of thermo-cracking for waste rubber tire.
Background technology
Along with China's automobile pollution rises year by year, there are every year a large amount of waste rubber tires to produce, these waste rubber tires are imbedded the underground degraded that is not only difficult for, also can be to environment.But waste rubber tire again whole body be precious, enjoy the good reputation of " black gold "; The raw material that in waste rubber, contained 12% steel wire is high-quality spring steel, contained 28%～35% reducible be carbon black, 49%～56% reducible be fuel oil.At present the treatment process of waste rubber tire is dropped in cracking still, to carry out scission reaction, then the carbon black of the steel wire of gained and reduction and fuel oil are reclaimed.Existing a kind of waste rubber splits still, this waste rubber splits still and includes the kettle being driven by rotating driving device, described kettle comprises by cylindrical shell and the end socket that is welded on these cylindrical shell two ends and forming, and end socket is at one end provided with feeding gate, is provided with air outlet at the barrel of described cylindrical shell.This waste rubber splits still, and there are the following problems in process of production: 1,, because waste rubber is the entirety cracking that feeds intake, often carry out a scission reaction and all will feed intake and take out after completion of the reaction steel wire, can not carry out continuously scission reaction operation, production efficiency is low; And waste rubber tire is feeding intake and cracking is complete will open the door of kettle one side when steel wire is transported from kettle, now, the remaining carbon black in kettle will be to external diffusion, not only contaminate environment, and the health that also can do to working hard workman works the mischief; 2, be rotated because kettle is driven by rotating driving device, air outlet is located at again on the barrel of cylindrical shell, and transportation pipe can only be communicated with air outlet at the top of cylindrical shell, therefore, and usually because the poor leakage that causes oil gas of stopping property of this junction; Often need shutdown maintenance, work-ing life is short, and production efficiency is low.
Utility model content
The problem that the utility model solves is to provide a kind of waste rubber cracking still feeding unit, can not continuously feeding and the poor problem of air outlet stopping property to solve existing waste rubber cracking still.
In order to address the above problem, the technical solution adopted in the utility model is: this waste rubber cracking still feeding unit comprises the kettle being driven by rotating driving device, described kettle comprises by cylindrical shell and the end socket that is welded on described cylindrical shell two ends and forming, on the described end socket at two ends, be respectively equipped with charging tubular shaft and discharging tubular shaft, described kettle is contained in frame by described charging tubular shaft and the hollow pedestal of described discharging, in described charging tubular shaft, be coated with the feeding screw stretching in described kettle, described kettle is provided with oil gas transfer passage in feed end, the air outlet of described oil gas transfer passage is enclosed and is formed by the feeding cylinder outer wall of described feeding screw and described charging tubular shaft,
Be connected with at described charging tubular shaft front end the pipe connecting being sleeved on described feeding cylinder, be provided with the graphite packing by compressing member crimping at described pipe connecting and described charging tubular shaft junction, be provided with by the gasket of pressing plate crimping in the junction of described pipe connecting and described feeding cylinder.
In above-mentioned waste rubber cracking still feeding unit technical scheme, technical scheme can also be more specifically: the air outlet width of described oil gas transfer passage is the poor of the internal diameter of described charging tubular shaft and the external diameter of described feeding cylinder, this air outlet width is described cylinder internal diameter 0.275～0.315 times.
Owing to having adopted technique scheme, the utility model compared with prior art has following beneficial effect: 1, because waste rubber changes the mode charging of passing through to adopt feeding screw charging outside cracking still after broken also magnetic separation steel wire into, the discharging of carbon black is undertaken by spiral discharging device equally, granular waste rubber can carry out continuously feeding and carry out scission reaction, need not establish feeding gate charging and unload steel wire; Cracking still adopts closed operation, and the carbon black in still can outwards not overflow contaminate environment, environmental protection, safety; 2, oil gas transfer passage is located at the purity that feed end can ensure that splitting gas is exported, and air outlet is located at the junction of end socket and the charging tubular shaft of kettle, the oil gas that the setting of the internal diameter of charging tubular shaft and the external diameter of feeding cylinder and kettle internal diameter and scission reaction produce matches; 3, because kettle is contained in frame by hollow pedestal, the sealing between charging tubular shaft and pipe connecting and the feeding cylinder of rotation adopts the graphite plate with self-lubricating, and good sealing effect, without oil gas leakage phenomenon, is convenient to maintenance, and annual only need changed once.
