Description
Technical field
The present invention relates to reactor manufacturing technology field, especially a kind of reactor for waste rubber tire being carried out thermo-cracking.
Background technology
Along with China's automobile pollution rises year by year, have a large amount of waste rubber tire to produce every year, these waste rubber tires are imbedded underground and are not only not easily degraded, also can to environment.But waste rubber tire again whole body be precious, enjoy the good reputation of " black gold "; In waste rubber, contained 12% steel wire is the raw material of high-quality spring steel, contained 28% ~ 35% reducible be carbon black, 49% ~ 56% reducible be fuel oil.Dropped in cracking still to carry out scission reaction to the treatment process of waste rubber tire at present, then the steel wire of gained and the carbon black of reduction and fuel oil are reclaimed.Existing a kind of waste rubber cracking still, this waste rubber cracking still includes the kettle driven by rotating driving device, the oil fuel burner heating described kettle and the still cover be fixed on outside described kettle, described kettle comprises and being made up of cylindrical shell and the end socket that is welded on these cylindrical shell two ends, and end socket is at one end provided with feeding gate.This waste rubber cracking still is suitable for and carries out scission reaction to large part waste rubber tire, production process is: first the waste rubber tire of large part is put into kettle from feeding gate and carry out scission reaction, react complete will open again, the spiral discharging device of activity is pushed in kettle and the reaction product carbon black of gained is transferred out kettle, again steel wire is transported from feeding gate afterwards.There are the following problems for the production method of this waste rubber cracking still: 1, because waste rubber is that entirety feeds intake cracking, often carry out a scission reaction and all will carry out feeding intake and taking out steel wire after completion of the reaction, can not carry out scission reaction operation continuously, production efficiency is low; And waste rubber tire will open the door of cracking still side when feeding intake and being transported from cracking still by steel wire with cracking is complete, now, the remaining carbon black in cracking still will to external diffusion, not only contaminate environment, also can work the mischief to the health doing workman of working hard; 2, the discharging of carbon black is incomplete, and loss is large; Carbon black residual in kettle is many, and cause when second throws in the waste rubber tire of large part, carbon black remaining in kettle flies out from feeding gate and fills the air in atmosphere, not only contaminate environment, also can work the mischief to the health doing workman of working hard.
Summary of the invention
Problem solved by the invention is to provide a kind of waste rubber cracking still, can not carry out scission reaction operation and heavy-polluted problem continuously to solve existing waste rubber cracking still.
In order to solve the problem, the technical solution used in the present invention is: this waste rubber cracking still comprises the kettle driven by rotating driving device, described kettle comprises and being made up of cylindrical shell and the end socket that is welded on described cylindrical shell two ends, the described end socket at two ends is 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, is coated with the feeding screw and spiral discharging device that stretch into described kettle respectively in described charging tubular shaft and described discharging tubular shaft;
Be provided with the spiral pusher plate for carbon black to be pushed into discharge end from feed end at the inwall of described kettle, be disposed radially polylith arc deflector at the end socket inwall of described discharge end side;
Described kettle is provided with oil-gas transportation passage in feed end, and the air outlet of described oil-gas transportation passage is enclosed by the feeding cylinder outer wall of described feeding screw and described charging tubular shaft and forms.
In above-mentioned waste rubber cracking still technical scheme, technical scheme can also be more specifically: described charging tubular shaft front end is connected with the pipe connecting be sleeved on described feeding cylinder, be provided with described charging tubular shaft junction the first graphite packing crimped by compressing member at described pipe connecting, be provided with the junction of described feeding cylinder the gasket crimped by pressing plate at described pipe connecting.
Further, the described discharge barrel barrel of nearly institute discharging tubular shaft axle head is provided with the second graphite packing crimped by crimp.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect: 1, because the raw materials for production of this waste rubber cracking still are particle waste rubbers after fragmentation, magnetic separation steel wire; Junked tire is first become by waste rubber crusher in crushing, by magnetic separator, steel wire is selected again, particle waste rubber enters in kettle by spiral discharging device and carries out scission reaction, the carbon black generated is sent by spiral discharging device, waste rubber cracking production process is accomplished continuously, close and produce, and the carbon black in cracking still can not outside diffuse pollution environment; 2, because kettle is contained in frame by hollow pedestal, the charging and discharging tubular shaft of rotation and pipe connecting and adopt the graphite plate with self-lubricating into and out of the sealing between barrel, good sealing effect, without oil gas leakage phenomenon, is convenient to maintenance, only need change once every year; 3, oil-gas transportation passage is located at feed end and can ensures the purity that splitting gas exports.
