Description
Technical field
The utility model belongs to chemical device technical field, and in particular to a kind of diaminotoluene reacts preheating device.
Background technology
Diaminotoluene is the important source material for preparing dimethythiotoluene diamine, and dimethythiotoluene diamine is a kind of novel
Polyurethane elastomer cure-crosslinking agent, wherein there are mainly two types of the mixed of isomers i.e. 2,4- and 2,6- dimethythiotoluene diamine
Object (ratio is about 77 ~ 80/17 ~ 20) is closed, is the relatively low liquid of viscosity compared with usually used MOCA, under room temperature, can fit
For constructing operation under low temperature, the advantages such as chemistry uses equivalent low.
Dimethythiotoluene diamine is in lewis acid catalyst by diaminotoluene and alkylating reagent dimethyl disulfide
In the presence of, generation is reacted at being 100 ~ 200 DEG C in temperature, diaminotoluene is toxic solid powder, and fusing point is 90 DEG C, research
It is reacted it was found that diaminotoluene is direct plungeed into reaction kettle with dimethyl disulfide, due to heating up, the uneven grumeleuse that is susceptible to shows
As influencing reaction yield.
Utility model content
The utility model provides a kind of diaminotoluene reaction preheating device, to solve diamino of the existing technology
Toluene heating is uneven to there is the problem of grumeleuse.
Technical solution is used by the utility model solves its technical problem：
A kind of diaminotoluene reacts preheating device, including auger type feeder, preceding air cooler, rear air cooler and wind turbine,
Fan outlet is connected with the shell side import of preceding air cooler, and dimethythiotoluene diamine reaction product enters the tube side of preceding air cooler,
Preceding air cooler tube side outlet is connected with rear air cooler tube side import, the shell side import phase of preceding air cooler shell-side outlet and rear air cooler
Even, auger type feeder is made of housing, chuck, motor, shaft and auger, and chuck is coated on surface of shell, rear air cooler
Shell-side outlet is connected with the hot wind inlet of chuck, and shaft is placed in enclosure interior, and auger is arranged in shaft, shaft one end and motor
It is connected.
The operation principle of the utility model is that diaminotoluene enters enclosure interior by import, and motor drives shaft rotation,
Auger is sent diaminotoluene powder to the outlet of the housing other end, at the same time dimethythiotoluene diamine reaction production by import
Object successively enters in preceding air cooler and rear air cooler, exchanges heat with the cold wind that wind turbine is sent, hot wind is led to by rear air cooler shell-side outlet
It crosses hot wind inlet to enter in chuck, diaminotoluene and hot air heat exchange in chuck, hot wind is finally by the hot-blast outlet of chuck end
Discharge, the diaminotoluene after preheating are entered by outlet in reaction kettle.
The utility model carries out heat exchange by cold wind and high-temperature reaction product and forms hot wind, and hot wind enters diamino in chuck
Toluene is preheated, and not only effectively increases the temperature uniformity of raw material diaminotoluene, and reaction waste heat is enable to utilize,
The performance driving economy of device is improved, there is simple in structure, stable and energy conservation and environmental protection.
Description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the structure diagram of the utility model.
Air cooler, 9 wind turbines, 10 behind air cooler before 1 housing, 2 chucks, 3 motors, 4 shafts, 5 augers, 6,7 outlets, 8 in figure
Hot wind inlet, 11 hot-blast outlets.
Specific embodiment
As shown in the figure, a kind of diaminotoluene reaction preheating device, including auger type feeder, preceding air cooler 6, rear air-cooled
Device 8 and wind turbine 9, the outlet of wind turbine 9 is connected with the shell side import of preceding air cooler 6, before dimethythiotoluene diamine reaction product enters
The tube side of air cooler 6, preceding 6 tube side of air cooler outlet are connected with rear 8 tube side import of air cooler, and preceding 6 shell-side outlet of air cooler is with after
The shell side import of air cooler 8 is connected, and auger type feeder is made of housing 1, chuck 2, motor 3, shaft 4 and auger 5, chuck 2
1 surface of housing is coated on, the shell-side outlet of rear air cooler 8 is connected with the hot wind inlet 10 of chuck 2, and shaft 4 is placed in housing 1
Portion, auger 5 are arranged in shaft 4, and 4 one end of shaft is connected with motor 3.
The operation principle of the utility model is that diaminotoluene enters enclosure interior by import, and motor drives shaft rotation,
Auger is sent diaminotoluene powder to the outlet of the housing other end, at the same time dimethythiotoluene diamine reaction production by import
Object successively enters in preceding air cooler and rear air cooler, exchanges heat with the cold wind that wind turbine is sent, hot wind is led to by rear air cooler shell-side outlet
It crosses hot wind inlet to enter in chuck, diaminotoluene and hot air heat exchange in chuck, hot wind is finally by the hot-blast outlet of chuck end
Discharge, the diaminotoluene after preheating are entered by outlet in reaction kettle.
