Fig. 2 is the schematic diagram of the water circulating pump of the present invention.
Fig. 3 is the reaction kettle schematic diagram of existing technical literature 1.
Fig. 4 is the reaction kettle schematic diagram of existing technical literature 2.
（Pay attention to：Shown structure in attached drawing simply to illustrate that feature of present invention signal, be not intended to according to attached drawing institute
Show structure.
Specific implementation mode
Pre-heated chemical reaction kettle is tiltedly arranged as shown in Figure 1, according to the present invention, including：Reaction tank 1, filter 2,
Stirring rod 3, water conservancy diversion conehead 4, paddle 5, outlet end 6, liquid feeding end 7 and water circulating pump 8.
Wherein, reaction tank 1 is columnar structured, and top is equipped with filter 2.Filter 2 is round sphere structure,
There is liquid feeding end 7, sphere lower part to be penetrated through with 1 top structure of reaction tank for sphere top side.So, from liquid feeding end 7 into
The liquid entered can be fallen into the opening at 1 top of reaction tank with larger area after the filtering of filter 2, be conducive to liquid and fill
The cycle divided is broken up.
Further, top columnar structured described in reaction tank 1 is also set up other than the interface of setting filter 2
There is stirring rod 3.
Paddle 5 is provided on the stirring rod 3, the symmetrical paddle 5 is in fishbone shaped formation, and opposite
In stirring rod 3 in certain angle of inclination.
It is equipped with water conservancy diversion conehead 4 in the lower part of stirring rod 3, the water conservancy diversion conehead 4 is rotary structure, and section is pentagon knot
Structure, lower end has water conservancy diversion cusp, and paddle 5 is 45-60 ° relative to the angle of inclination of stirring rod 3.Water conservancy diversion conehead 4 one
Liquid after aspect stirs agitated leaf 5 from top to down carries out water conservancy diversion, on the other hand from top to bottom to rising behind bottom
Liquid carry out water conservancy diversion, therefore with two-way guide functions up and down, can realize other blade forms tool than in the prior art
There is better mixing effect.
Preferably, the width of paddle 5 is between 1-2cm, most preferably 1.5cm.
Further, the bottom of reaction tank 1 is provided with water circulating pump 8, the wherein entrance of water circulating pump 8 upward, faces
The position of 3 lower end of stirring rod.Such mechanism design, enables to filter by filter 2, using water conservancy diversion conehead 4 and stir
Mix the inlet that the liquid after leaf 5 stirs drops into water circulating pump 8.
Also, as shown in Fig. 2, water circulating pump 8 is two export structures, i.e., it is each provided with one in the both sides of water circulating pump 8
Water outlet 9, the two water outlets 9 are arranged relative to the circular pump housing in symmetrical structure, and export direction is tangential on the pump housing
Circumference.Therefore, recirculated water can be discharged in the two symmetrically arranged water outlets 9 in two directions, so as to realize uniformly
Ringing, rather than from top as the prior art, or water cycle is only carried out from a direction.
Preferably, a rotatable chassis is arranged in 8 lower part of water circulating pump, due to two water outlets 9 in two export structures
It is arranged in symmetrical structure relative to the circular pump housing, therefore the propulsive thrust of flow can act on the pump housing so that water circulating pump 8 exists
It is slowly rotated on chassis, to be more conducive to the outflow of flow in different directions, contributes to the abundant realization of water cycle.
Further, in the other side of 1 bottom of reaction tank, i.e., the side opposite with liquid feeding end 7 is provided with outlet end 6.Cause
This, liquid can enter from the side of reaction tank 1, and effect is sufficiently stirred through water conservancy diversion conehead 4 and paddle 5, then from the other side
Outlet end 6 flows out.Also, it, can be by the liquid band for being not easy to stir of bottom deposit due to the effect of the water circulating pump of bottom 8
It is dynamic, to realize the staggered form cycle of entire reaction tank 1.
Further, the bottom of reaction tank 1 is provided with heating plate 10, the heating plate 10 is arranged in water circulating pump 8
Lower part.Wherein, water circulating pump 8 is set up directly on the middle position in heating plate 10, and heating plate 10 is only outside water circulating pump 8 at this time
Circle fever, without influencing whether water circulating pump 8.When water circulating pump 8 has rotatable chassis, then chassis, which is similarly disposed at, adds
Middle position on hot plate 10, heating plate 10 is only in the fever of 8 chassis outer ring of water circulating pump at this time, without influencing whether water circulating pump
8 chassis.
As a result, when heating plate 10 heats, since the liquid in reaction tank 1 is all in the superjacent air space of heating plate, and
Rise according to the liquid after heating, the principle that not heated liquid declines, it is easy to which the liquid in entire reaction tank 1 is carried out
Adequately heating.Also, since water circulating pump 8 is arranged in the top of heating plate 10, secondly export structure, it can be in both direction
Upper discharge recirculated water, so as to realize uniform ringing.
Above description tiltedly arranges pre-heatedization tiltedly to arrange pre-heated chemical reaction kettle according to of the present invention based on above-mentioned
Work reaction kettle, workflow are：
Step 1：Liquid is entered from the liquid feeding end 7 of 1 top side of reaction tank in spherical filter 2；
Step 2：After filter 2 is filtered the liquid of entrance, liquid enters 1 top of reaction tank through 2 bottom of filter
Opening in；
Step 3：Into the liquid of reaction tank 1, it is sufficiently stirred by the paddle 5 in fishbone shaped formation, and pass through
The guide functions of water conservancy diversion conehead 4；
Step 4：Two water outlets 9 through 8 both sides of water circulating pump are discharged after bottom liquid is sucked by water circulating pump 8, again
Liquid after being stirred with water conservancy diversion conehead 4, paddle 5 realizes cross-circulation；
Step 5：Meanwhile the bottom liquid partly not sucked by water circulating pump 8 is by the heating plate 10 of 1 bottom of reaction tank
Heating；
Step 6：Liquid after heating further realizes cross-circulation with the above-mentioned liquid after stirring；
Step 7：6 row of outlet end of reacted 1 other side of pond of liquid after above-mentioned steps are heated and are sufficiently mixed
Go out, completion is stirred to react process.
It is according to the present invention tiltedly to arrange pre-heated chemical reaction kettle and have the characteristics that：
（1）Liquid mode is entered using top, and liquid can be broken up after filtering, is tentatively mixed；
（2）Paddle 5 is in fishbone shaped formation, using oblique row's mode, can realize sufficient stirring action；
