For example application number is that 201010534601.2 Chinese invention patent application discloses a kind of reactor, comprise charging aperture, discharging opening, shaft and be arranged on agitator, temperature control equipment on the shaft, establish the mozzle that can be moved up and down along charging aperture by motor-driven in the charging aperture; Shaft is provided with mixer., dasher and gate stirrer from top to bottom successively; Temperature control equipment is one to be arranged on a plurality of tube chambers on the shaft, each tube chamber is divided into two independently heated chamber and cooling chamber, the centre is isolated by a thermal insulation board, the each several part of heated chamber and separate chamber does not all contact, the heating source that reactor peripheral hardware and heated chamber are communicated with and the cooling source that is communicated with cooling chamber.
Mixed effect and reaction efficiency when agitating device directly affects reaction in the reactor, therefore, according to different demands, the improvement research of being devoted to mixing plant in the reactor is more, for example, application number is that the Chinese utility model patent of 201120296359.X discloses a kind of reactor paddle, and double-deck disc type paddle is arranged, and the disc type paddle is installed on the main shaft by bolt; The disc type paddle is blade, and blade has the first blade, the second blade to be installed on the main shaft, between the first blade, the second blade spacing is arranged; Pore size distribution is arranged on the blade; The outline of blade is polygon.
Again for example, application number is 00211838.6 1 kinds of frame type stirrers.Be fixedly connected with sleeve on the shaft of this agitator, be welded with the transverse slat perpendicular to sleeve on the sleeve, the relevant position is fixedly connected with the strip side that each transverse slat is connected as a single entity with bolt on the transverse slat, thus the composing plate gate stirrer.
As shown in Figure 1, it is a kind of existing stamp reactor, comprise kettle 1, be positioned at some reverse flow baffles 3 of kettle 1 inwall, vertically be arranged on the shaft 2 of kettle 1 and be fixed on frame type agitating blade 4 on the shaft 2, frame type agitating blade 4 is by some horizontal frames that are parallel to each other and the side that horizontal frame is connected successively, horizontal frame and shaft 2 are fixing, side and horizontal frame are fixed, and horizontal frame is interconnected and fixed.There is following shortcoming in the agitating device of this reactor: frame type agitating blade 4 is excessive apart from the distance of kettle 1 inwall, and the material stirring that is positioned at kettle 1 inwall and bottom is not thorough, and reaction not exclusively.
The utility model content
The utility model provides a kind of reactor that improves paddle, by the improvement to paddle, the interior material of reactor can fully be mixed react, and enhances productivity.
A kind of reactor that improves paddle comprises kettle, vertically is arranged on the shaft in the kettle and be fixed on frame type agitating blade on the shaft, and the side of described frame type agitating blade and the distance between the inner wall of kettle are 1/10～1/6 of kettle internal diameter.
During work, reaction mass is sent in the kettle, stirring by frame type agitating blade makes the abundant hybrid reaction of material, by increasing the width of paddle, reduce the distance between paddle side and the inner wall of kettle, strengthen the mixed effect of material, the interior all materials of kettle can both be stirred fully, the dead angle can not occur stirring.
With regard to shown in regard to the frame type agitating blade, can process on existing frame type agitating blade basis, preferably, described frame type agitating blade comprises horizontal frame and two described sides that are connected horizontal frame that some and shaft are fixing.
More preferably, described kettle volume is 20～30m
3, the spacing between described side and the inner wall of kettle is 30～50cm.
Most preferably, the volume of described kettle is 20～30m
3, the spacing between described side and the inner wall of kettle is 35cm.
Be 20～30m for volume
3Kettle, the side of frame type agitating blade and the spacing between the inner wall of kettle are 30～50cm, optimum when be 35cm, the material in the kettle can access to greatest extent and mix, the dead angle appearance is not stirred at the inner wall of kettle place.
After increasing the width of frame type agitating blade, can improve accordingly frame type agitating blade apart from the distance of autoclave body bottom, therefore, in the utility model, in order to guarantee the mixing effect of kettle inner bottom part when increasing the paddle width, preferably, described horizontal frame is set to 3～5, be positioned at a middle part of bottom to lower process, and form acute angle between the described shaft.
More preferably, described acute angle is 60～80 degree.
Most preferably, described acute angle is 75 degree.
For further increasing the stirring and mixing effect of material in the kettle, the height of described side is 1/2 of kettle height.
The beneficial effects of the utility model:
In traditional reactor, its frame type agitating blade is excessive apart from the distance of inner wall of kettle, and the material stirring that is positioned at inner wall of kettle and bottom is not thorough, and reaction not exclusively.Reactor of the present utility model by increasing the width of paddle, reduces the distance between paddle side and the inner wall of kettle, strengthens the mixed effect of material, and the interior all materials of kettle can both be stirred fully, the dead angle can not occur stirring.
