Description

Rolling-pot type waste rubber pyrolyzer

The utility model relates to a kind of device that transmits solid material and solid material is carried out sorting in air-flow with the cracked oil air-flow, the especially device that waste rubber grain is decomposed with the reactor that rotates.

Growing along with social progress and suitability for industrialized production, the processing of waste rubber become day by day environmental protection key subjects, uselessly be placed on greatly in the physical environment as glue quantity, floor space is big, be difficult for natural decomposition, orthobiosis and vegeto-animal growth that influence is human.Therefore, real for the disaggregating treatment of waste rubber is the task of top priority.Each state-owned two kinds of cracking waste rubber device of our times, first kind is single still formula cracker, it relatively simple for structure, but complex operation can not continuous production, and yield poorly, safety inadequately, thereby be not suitable for suitability for industrialized production.Second kind is the agitator type cracker.As Fig. 1, be communicated with a garden cartridge type cracking screw feeder D in process furnace C side, this screw feeder D is by step-down gear E driven rotary, and waste rubber grain A enters cracking screw feeder D from opening for feed B, by process furnace C heating, flows out from mixing discharge port F after making waste rubber grain A cracking.This apparatus structure complexity, manufacture difficulty is big, cost is higher, exist two problems, the one, failure rate is higher, the secondth, rubber is in the slowly motion forward of the bottom of screw feeder during cracking, and the carbon black that the rubber particle surface cracking forms can not come off immediately fully, thereby has influenced the rate of cleavage of deep layer rubber.

The purpose of this utility model is to propose a kind of rolling-pot type waste rubber pyrolyzer that can carry out suitability for industrialized production, and it reclaims important industrial raw material carbon black and oil, and at the same time carbon black is separated with oil when handling waste rubber.

Utility model is achieved in that a kind of rolling-pot type waste rubber pyrolyzer, comprise the feed-pipe 41, the gas-solid separator 6 that are connected by the charger 4 of step-down gear control rotating speed, with charger, the pyrolyzer 5 that is communicated with process furnace 56, it is characterized in that: be provided with in the pyrolyzer and roll still 51 by electric reducer structure 54 driven rotary, the described affixed sealing bore 57 in still the place ahead that rolls, the feed-pipe 41 be communicated with charger is set respectively in the described sealing bore, lead to gas-solid separator 6 circulation oil gas escape pipe 61, lead to the circulation oil gas muffler 65 of gas solid separation blower fan 63; The still 51, feed-pipe 41, circulation oil gas escape pipe 61, gas-solid separator 6, circulation oil gas muffler 65, gas solid separation blower fan 63 that roll of described pyrolyzer forms the rolling-pot type waste rubber pyrolyzer of working continuously.Roll and set firmly material rotating plate 52 and abrading-ball 50 in the still 51.Gas, solid separator 6 are the cyclone type gas-solid separator, are communicated with carbon black discharging machine 7 in the lower end of described gas-solid separator.The oil gas condenser 64 of refiltered oil is communicated with charger 4 by oil transportation, tracheae 66.

The utility model is compared with the agitator type cracker, and under consumable material, energy consumption, the identical prerequisite of investment, cracking output improves 2-3 doubly.And energy Separation and Recovery essential industry raw material: carbon black and mixing oil.

Now further narrate structure of the present utility model and course of action in conjunction with the accompanying drawings:

Referring to Fig. 2-5: place the waste rubber grain of well cutting in advance on feeding platform 1, by the input speed of charging step-down gear 2 control chargers 4, charger 4 one sides top is provided with hopper 3, and the feed-pipe 41 of charger stretches in the sealing bore 57 of pyrolyzer 5.The circulation oil gas escape pipe 61 that is connected with pyrolyzer sealing bore 57, to roll the powdery carbon black and the oil gas mixture input gas-solid separator 6 of 52 upsets of still inwall material rotating plate by pyrolyzer, by gas-solid separator 6 separating off carbon black and oil gas, and respectively carbon black is sent into carbon black discharging machine 7, oil gas is sent into turning oil, gas muffler 65, discharge waste gas and flow out the oil that reclaims by oil gas condenser 64.So, the transport unit that the circulation oil gas that is connected of pyrolyzer and sealing bore 57 goes out,

muffler

61,65,62 gas-solid separators 6, gas solid separation blower fan 63 form a circulation sealing.

Pyrolyzer 5 is arranged at process furnace 56 tops and is communicated with it, drive by the power set of rolling still bearing 59 connecting band step-down gears and roll still 51 rotations, in the inboard of rolling still by affixed material rotating plate 52 at interval.Opposite side at pyrolyzer sets firmly sealing bore 57, one end of sealing bore 57 stretches into and rolls the still inner chamber, and end connects three pipelines in addition, promptly leads to the feed-pipe 41 of charger 4, the circulation oil gas escape pipe 61 that leads to gas-solid separator 6 leads to turning oil, the gas muffler 65 of gas solid separation blower fan 63.Carbon black discharging machine 7 is connected the lower end of gas-solid separator 6.Roll filling thermal insulation furnace body 58 between the housing of still 51 and the stove outside.The power set that is positioned on the step-down gear platform 53 is rolled still 51 according to 24 rev/mins speed rotation by rolling still bearing 59 order, being positioned over abrading-ball 50 that rolls in the still and the waste rubber grain of sending into by feed-pipes 41 in the sealing bore 57 rolls under the temperature that process furnace 56, air regulating port 55 keep and bumps mill, make rubber grain under this temperature by the table inside cracking, the carbon black of rubber surface is bumped to grind and is come off in the process of rolling, and makes further rubber obtain heat very soon and decomposes.This is big, the fireballing reason of the utility model treatment capacity place.Roll after cracking begins two kinds of products, the one, powdery carbon black, the 2nd, oil gas are arranged in the still 51, oil gas is separated by cyclone type gas-solid separator 6 time rolling the circulation of recycle system high speed, the carbon black that still 51, pipeline and gas-solid separator 6 constituted as the sooty carrier, after rolling oil gas in the still 51 and reaching some amount, discharge to enter in the oil gas condenser 64 by feed-pipe 41 and be condensed into mixing oil.Rolling still charging and cracking process successively carries out.
