In order to realize above-mentioned technical purpose, the technical solution of the utility model is, a kind of reactor, the reaction kettle body that comprises hollow, agitating device, heater, bracing or strutting arrangement, described bracing or strutting arrangement comprises support and the supporting seat of hollow, described reaction kettle body is arranged in the support, described supporting seat is arranged at frame bottom and supports reaction kettle body, described heater is arranged between support and the reaction kettle body, the top of described reaction kettle body is provided with the kettle cover that is screwed on reaction kettle body, described kettle cover is provided with charging aperture, the bottom of reaction kettle body and support is provided with the discharging opening of connection, described agitating device comprises stirring motor, power transmission shaft, secondary paddle, main paddle and screw rod paddle, described stirring motor is fixed in outside the kettle cover at reaction kettle body top by frame, stirring motor is connected in power transmission shaft in the reaction kettle body, described secondary paddle by shaft coupling, main paddle and screw rod paddle are fixed on the power transmission shaft from top to bottom successively.
Described a kind of reactor, described secondary paddle is pusher paddle.
Described a kind of reactor, described main paddle are anchor formula paddle, the bottom of the radian of the blade outer rim camber line of main paddle and blade haptoreaction kettle identical with the bottom camber line radian of reaction kettle body.
Described a kind of reactor, the blade quantity of described main paddle are three.
Described a kind of reactor, described screw rod paddle is arranged in the discharging opening, and the upper end of screw rod paddle is higher than the upper end of discharging opening, and screw rod paddle lower end is concordant with bottom, discharging opening lower end.
Described a kind of reactor is characterized in that, the bending blade opposite direction of described main paddle and secondary paddle.
Technique effect of the present utility model is, during charging, the stirring motor forward, the material that flow in the discharging opening is also taken to the reaction kettle body bottom with the rotation of screw rod paddle again by rising, solve partial material in the discharging opening and be difficult to the problem that participates in reacting, be conducive to the abundant mixing of material.The reaction kettle body inner chamber stirs and changes many agitating devices into by single agitating device, and main paddle and secondary paddle intersect and oppositely arrange, material forms in opposite directions and flows, cooperate again the screw rod paddle, greatly improved stirring efficiency, material in the kettle is fully mixed, thereby improve the quality of products, avoided the inadequate problem of material reaction.
During discharging, stirring motor counter-rotating, the material in kettle and the discharging opening is taken out of with the screw rod paddle, and discharging speed is controlled by stirring motor, has avoided that the viscous material discharging is too slow, the too fast phenomenon of fluid foods discharging, has improved stability and the security of producing.Contact with the reactor intracavity bottom owing to this novel reaction kettle master paddle simultaneously, the bottom material can bring to discharging opening with main paddle when discharging, material brings to the discharging opening bottom by the screw rod paddle again, thoroughly solves the problem of bottoms material, has promoted utilization of materials.That this novel reaction kettle has is easy to operate, stirring efficiency is high, and material takes full advantage of, the characteristics of security of operation.
The utility model is described in further detail below in conjunction with accompanying drawing.
