Furthermore, the number of the blades is 2-4.

Furthermore, a plurality of groups of barbed edges are paved at the bottom of the anchor frame.

Further, the outside of the jacket is wrapped with a thermal insulation sleeve.

Furthermore, the height of the heat-conducting liquid in the jacket is 1/3-2/3 of the depth of the jacket.

Further, the radius of each screw is smaller than the length of each single group of blade and the length of each anchor frame.

Compared with the prior art, the utility model discloses beneficial effect includes:

(1) the heating coil pipe which is arranged in the concave part and spirally wound is adopted, and the heat conducting liquid filled in the jacket is combined, so that the kettle body can be heated more efficiently; set up simultaneously and realize that runoff, lower axial-flow type rabbling mechanism for the stirring is more abundant.

Illustration of the drawings: 1-kettle body, 2-jacket, 3-stirring shaft, 4-heating coil, 5-heat conducting liquid, 6-barbed edge, 7-anchor frame, 8-screw, 9-heat insulating jacket and 10-paddle.

In the description of the present invention, the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted", "connected" and "connected" are to be interpreted broadly, and may be, for example, fixedly connected, detachably connected, integrally connected; can be mechanical connection and electrical connection; may be directly connected, indirectly connected through intervening agents, or may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood to be specific to those skilled in the art.

Detailed Description

The present invention will be further described with reference to the accompanying drawings.

As shown in fig. 1, a reation kettle for dichloro benzophenone production, including the cauldron body 1, the parcel is at the outside of the cauldron body 1 and the clamp cover 2 of bottom, and the cauldron body 1 is the material of going up feeding ejection of compact down, sets up rabbling mechanism in the cauldron body 1, and the lateral wall portion indent of the cauldron body 1, the spiral winding heating coil 4 is installed to the indent, and heating coil 4 is regional to be wrapped up by pressing from both sides cover 2, packs heat-conducting liquid 5 in pressing from both sides cover 2, at the reaction heating in-process for its bottom is difficult for installing heating element's regional thermally equivalent. The concave arrangement and the spiral winding of the heating coil pipe 4 can enable the kettle body 1 to be heated more efficiently, and the heating coil pipe 4 is equivalent to the embedded arrangement. The heat conducting liquid 5 is a high temperature resistant liquid allowed in the art, such as heat conducting oil, and will not be described in detail.

In order to make the stirring abundant, and then make the material be heated more evenly when the cauldron body 1 internal reaction, rabbling mechanism is radial axial complex stirring spare, and the rabbling mechanism includes (mixing) shaft 3 and installs the agitator on (mixing) shaft 3, and agitator top-down is blade 10, screw rod 8, anchor frame 7 in proper order, and then realizes the stirring of runoff, axial-flow type down, and blade 10 quantity is 2 ~ 4 pieces.

And a plurality of groups of barbed edges 6 are laid at the bottom of the anchor frame 7, so that the stirring efficiency is further improved.
