Background technology
Traditional reactor that is used for synthetic resin comprises kettle and agitating device, and kettle is provided with charging aperture and discharging opening, and charging aperture and discharging opening all are communicated with the cavity of kettle, and wherein charging aperture is located at the upper end of kettle; Agitating device comprises agitator and stirrer-driven mechanism, and stirrer-driven mechanism is installed on the kettle, and agitator is in the cavity of kettle and with the stirrer-driven mechanism driving and is connected.Because charging aperture is located at the upper end of kettle, therefore when material enters the cavity of kettle, partial material is stirred device and is thrown to inner wall of kettle or sagging along inner wall of kettle automatically, so that material hot-spot or local reaction (as local implode), make unstable product quality, generate the graininess waste residue, influence the stability and the recovery rate of product.
Summary of the invention
Technical problem to be solved in the utility model provides and a kind ofly can make constant product quality and the high reactor of recovery rate.The technical scheme that adopts is as follows:
A kind of reactor comprises kettle and agitating device, and kettle is provided with charging aperture and discharging opening, and charging aperture and discharging opening all are communicated with the cavity of kettle, it is characterized in that: described charging aperture is located at the bottom of kettle or the bottom of kettle sidewall.
Usually agitating device comprises agitator and stirrer-driven mechanism, and stirrer-driven mechanism is installed on the kettle, and agitator is in the cavity of kettle and with the stirrer-driven mechanism driving and is connected.When above-mentioned charging aperture was located at the bottom of kettle sidewall, charging aperture was in the below of agitator, can not be stirred device with the material of guaranteeing just to enter the kettle cavity and be thrown to inner wall of kettle; When charging aperture was located at the bottom of kettle, charging aperture obviously was in the below of agitator, and the material that can guarantee just to have entered the kettle cavity can not be stirred device and be thrown to inner wall of kettle.
Specifically, above-mentioned agitator comprises shaft and is fixedly mounted on puddle support, stirring vane or stirring arm on the shaft, and shaft is connected with the stirrer-driven mechanism driving, and puddle support, stirring vane or stirring arm are installed in the bottom of shaft usually.When above-mentioned charging aperture was located at the bottom of kettle sidewall, charging aperture was in the below of puddle support, stirring vane or stirring arm.
Usually, stirrer-driven mechanism comprises motor, and motor mounting is on kettle, and the shaft of agitator is connected with the output shaft of motor by shaft coupling; Perhaps stirrer-driven mechanism comprises motor and decelerator, and decelerator is connected with electric-motor drive, and motor and decelerator are installed on the kettle, and the shaft of agitator is connected with the output shaft of decelerator by shaft coupling.During motor operation, its output shaft drives shaft and rotates (when being provided with decelerator, the output shaft of motor driving reducer rotates, the output shaft of decelerator drives shaft and rotates), thereby puddle support, stirring vane or stirring arm are rotated around shaft, the material in the cavity of kettle is stirred.
In a concrete scheme, the outside of kettle is provided with chuck, forms mezzanine space between chuck and the kettle, and chuck is provided with steam entry, condensation-water drain, cooling water inlet and the coolant outlet that is communicated with mezzanine space.When from steam entry to mezzanine space during the transporting water steam, steam can be to the heating of the material in kettle and the kettle cavity, material is heated up and reaches the required temperature of reaction, the water that steam heat radiation back produces is discharged from condensation-water drain; When needs cool off kettle, can to mezzanine space, carry cold water from the cooling water inlet, cold water contacts with kettle and makes its cooling, and the higher water of the temperature of generation is discharged from coolant outlet.
Above-mentioned discharging opening is located at the bottom of kettle usually.
The utility model is owing to be located at the bottom of kettle or the bottom of kettle sidewall with charging aperture, therefore when material enters in the cavity of reactor from charging aperture, can be stirred immediately, and evenly be heated to the required temperature of reaction, guarantee to react and normally carry out, thereby make constant product quality, and the recovery rate height, be suitable for synthetic resin, be particularly suitable for producing the synthetic of resin in the laser transfer coatings.

The specific embodiment
Embodiment 1
As shown in Figure 1, this reactor comprises kettle 1 and agitating device.
Kettle 1 is provided with charging aperture 2 and discharging opening 3, and charging aperture 2 and discharging opening 3 all are communicated with the cavity 4 of kettle 1; Charging aperture 2 is located at the bottom of kettle 1 sidewall, and discharging opening 3 is located at the bottom of kettle 1.
The outside of kettle 1 is provided with chuck 5, forms mezzanine space 6 between chuck 5 and the kettle 1, and chuck 5 is provided with steam entry 7, condensation-water drain 8, cooling water inlet 9 and the coolant outlet 10 that is communicated with mezzanine space 6.
Agitating device comprises agitator and stirrer-driven mechanism; Agitator comprises shaft 11 and is fixedly mounted on puddle support 12 on the shaft 11, and puddle support 12 is installed in the bottom of shaft 11, and shaft 11 and puddle support 12 all are in the cavity 4 of kettle 1, and charging aperture 2 is in the below of puddle support 12; Stirrer-driven mechanism comprises motor 13 and decelerator 14, and motor 13 and decelerator 14 are installed on the kettle 1 by pedestal 15, and decelerator 14 is in transmission connection with motor 13; The shaft 11 of agitator is connected with the output shaft 17 of decelerator 14 by shaft coupling 16.
Brief description is the operation principle of this reactor once: when from steam entry 7 to mezzanine space 6 during the transporting water steam, steam can heat the material in the cavity 4 of kettle 1 and kettle 1, make the material intensification and reach the required temperature of reaction, the water that steam heat radiation back produces is from condensation-water drain 8 discharges; During motor 13 runnings, the output shaft 17 that drives decelerator 14 rotates, and the output shaft 17 of decelerator 14 drives shaft 11 and rotates, thereby puddle support 12 is rotated around shaft 11; When material entered in the cavity 4 of kettle 1 from charging aperture 2, puddle support 12 promptly stirred material, made mixing of materials evenly and react; The product that the reaction back obtains is discharged from discharging opening 3.
When needs cool off kettle 1, can to mezzanine space 6, carry cold water from cooling water inlet 9, cold water contacts and makes its cooling with kettle 1, and the higher water of the temperature of generation is discharged from coolant outlet 10.
Embodiment 2
As shown in Figure 2, the charging aperture 2 of this reactor is located at the bottom of kettle 1, and all the other structures are identical with embodiment 1.
In other embodiments, agitator also can comprise shaft and be fixedly mounted on stirring vane or stirring arm on the shaft that stirring vane or stirring arm are installed in the bottom of shaft usually.Stirrer-driven mechanism also can comprise motor, and motor mounting is on kettle, and the shaft of agitator is connected with the output shaft of motor by shaft coupling.
