Embodiment
Concrete mechanism below in conjunction with the description of drawings embodiment of the present invention:
As shown in Figure 1, the present invention includes Fu body (1), Fu lid (2), frame type agitating blade (3), magnet coupler (4), motor (5), heating furnace (6) and device for discharging (27).
As shown in Figure 2, frame type agitating blade of the present invention (3) is combined by side scraper (7), end scraper (8) and two blade (9).Angle between the tangent plane of the side blade face of frame type agitating blade and cylindrical shape Fu wall on direction of advance in the evaporating solvent process, can reduce and scrape the resistance that wall stirs like this greater than 90 ℃.Frame type agitating blade adopts pole (10) to be connected with axle and supports, and can reduce to splice resistance, thereby reduces power consumption.When being clamminess fouling, material is easy to cleaning.End scraper is adopted in the bottom, and the angle between knife face and the reactor bottom surface on direction of advance is greater than 90 ℃, and is simple in structure, is convenient to guarantee scraper intensity, with the gap uniformity at the bottom of the Fu, the effect of upwards stirring of material also strengthened.Two blades have mainly played the homodisperse effect of batch mixing that makes.This blender can be realized stepless speed regulation.
As shown in Figure 3, magnet coupler of the present invention (4) is made up of inside and outside annular magnet steel, stirs power and is transmitted by inside and outside magnet steel magnetic force by servomotor.Outer magnet (11) links to each other with motor by belt, and inner magnetic core (12) links to each other with shaft, works as electric motor starting, drives outer magnetic sleeve and does gyration, and inner magnetic core is that blender and outer magnetic sleeve are done synchronous gyration, thereby medium is stirred; Spacer is equipped with hall sensing element (13) outward, and when dressing up the rotation of the blender of one and interior magnet steel, the frequency that Hall element just produces pulse is with to stir speed corresponding, after the single-chip microcomputer processing in order to the demonstration and the adjusting of speed of agitator; In reaction Fu heating process, the temperature of magnet coupler can raise, and protects magnet coupler by cooling water pipe.
As shown in Figure 4, Fu of the present invention lid (2), reasonable, and simple in operating process for each component distribution that Fu is covered, therefore aspect the Design Treatment of Fu lid, the present invention is assemblied in motor on the Fu body, makes to open the easy to operate of Fu lid; Thermocouple (20) design is covered being installed on Fu, make that the temperature control in the material preparation process is more accurate, can transfer temperature in the Fu to the signal of telecommunication accurately, pass to digital temperature instrument on the controller, show temperature in the Fu by lead; Fu is covered with pressure vacuum gauge (18), gas or liquid phase valve (19), thermocouple (20), gas vent (21), handle (22), safety valve (23) and liquid or solid charge door (24), be provided with valve (25) and articulation (26) at gas outlet, can make and obtain required requirement for experiment condition in the Fu, can feed in raw material at any time, owing to be provided with articulation (26) at gas outlet, then clean gas outlet tube at any time stops up with harm.
As shown in Figure 5, the reaction Fu bigger to volume can assemble device for discharging (27), and its kettle cover can move up and down, and heating furnace can move up and down, and makes reaction kettle body break away from heating furnace, and the rotation discharging, makes convenient experimental operation, hommization more.The reaction Fu less to volume also realizes the manual cleaning.
