The reaction kettle comprises a kettle body, a kettle cover, a jacket, a stirrer, a transmission device, a shaft seal device, a support and the like. When the height-diameter ratio of the stirring device is larger, a plurality of layers of stirring blades can be used, and the stirring device can be randomly selected and matched according to the requirements of users. The jacket is arranged outside the kettle wall, or a heat exchange surface is arranged in the kettle, and the heat exchange can be carried out through external circulation. The supporting seat is provided with a supporting type or an ear type supporting seat and the like. The gear reducer is suitable for use when the rotating speed exceeds 160 turns, and the number, specification or other requirements of the holes can be designed and manufactured according to the requirements of users.
The defects of the prior art are as follows: the reaction kettle is stirred based on the stirring paddle, the stirring paddle is generally fixed at the tail end of the stirring rod, when the height-diameter ratio of the stirring device is larger, multiple layers of stirring paddles can be used, however, due to the fixed installation of the stirrer, the stirring area is fixed, the stirring time is set, the materials can be stirred uniformly, and the stirring device is not suitable for rapid stirring.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art not enough, provide a medical reation kettle of high-efficient stirring, set up fixed stirring rake and mobilizable stirring rake to make the stirring region reciprocate in reation kettle, can effectively shorten the time of stirring, thereby realize the high-efficient stirring.
The purpose of the utility model is realized through the following technical scheme:
the utility model provides a high-efficient medical reation kettle that stirs, includes the cauldron body and kettle cover, a driving motor is fixed at the kettle cover top, and driving motor's pivot passes through liquid seal bearing with the kettle cover and is connected, and driving motor's pivot is passed and is connected with a puddler behind the liquid seal bearing, the terminal fixed connection stirring rake of puddler still includes one and is provided with the internal screw thread sleeve, the puddler along the axial be provided with interior screw-thread fit's external screw thread, the sleeve cup joints on the puddler through the screw thread, and sleeve bilateral symmetry is fixed with two piece at least connecting rods, the connecting rod is fixed with the board oar, driving motor realizes periodic just reversing by PLC or adoption positive and negative pulse power.
This scheme is equivalent to increased a movable oar that can rise and descend on traditional reation kettle's puddler to make the stirring region become to remove, can cover whole cauldron internal in a cycle, in order to accomplish the rising and the decline of activity oar, this scheme utilizes the resistance of stirring in-process and combines the screw thread on the puddler to make it take place relative movement, and the rising and the decline of activity oar are accomplished through driving motor's positive and negative rotation.
In a first step, the paddle is provided with a through hole. The design is to form turbulent flow in the stirring area so as to accelerate the uniform stirring speed.
In a first improvement, the stirring rod is in a shape of Chinese character shan, and the length of the connecting rod is smaller than the transverse width of the stirring rod, so that the whole formed by the sleeve, the connecting rod and the plate paddle can be screwed into the stirring rod.
In the first step, a rapid charging opening is formed in the kettle cover. The charging time can be shortened through the quick charging opening.
In a first step, the kettle cover is provided with a protective cover outside the liquid seal bearing.
In the first step, the plate paddles are connected with the connecting rod through threads, so that the plate paddles are convenient to clean.
The utility model has the advantages that:
(1) the scheme utilizes the movable paddle consisting of the sleeve, the connecting rod and the plate paddle, and spirally lifts up and down in a threaded manner, so that the migration of the stirring area is completed, and the stirring area can cover the whole kettle body in the stirring process;
(2) the through holes are formed in the plate paddles, which is equivalent to a turbulent flow area formed in the stirring area, so that uniform mixing can be accelerated, and the stirring efficiency is further improved.

Detailed Description
The technical solution of the present invention is described in further detail below with reference to the accompanying drawings, but the scope of the present invention is not limited to the following description.
As shown in figure 1, a high-efficient medical reation kettle that stirs, including the cauldron body 1 and kettle cover 2, a driving motor 6 is fixed at kettle cover 2 top, and driving motor 6's pivot is connected through liquid seal bearing 5 with kettle cover 2, and driving motor 6's pivot is connected with a puddler 3 after passing liquid seal bearing 5, and puddler 3 end fixed connection stirring rake 4. In order to make the stirring area change continuously or cover the whole reaction kettle with the stirring area, a movable paddle is also provided in the embodiment, and the movable paddle is composed of a sleeve 9, a connecting rod 10 and a plate paddle 11. Sleeve 9 is provided with the internal thread, and puddler 3 is provided with along the axial with interior screw-thread fit's external screw thread, and sleeve 9 cup joints on puddler 3 through the screw thread, and sleeve 9 bilateral symmetry is fixed with two piece at least connecting rods 10, and connecting rod 10 is fixed with board oar 11, and driving motor 6 realizes the periodic positive and negative rotation by PLC or adoption positive and negative pulse power. In the process of forward and reverse rotation, because the resistance borne by the plate paddle 11 is large, a rotation speed difference is formed between the sleeve 9 and the stirring rod 3, the sleeve 9 is equivalently spirally lifted or lowered along the stirring rod 3 under the action of the rotation speed difference, the movable paddle can be lifted up and down by controlling the driving motor 6 to perform periodic forward and reverse rotation, and thus the stirring area covers the whole kettle body 1, and rapid stirring is realized. In order to further promote the stirring effect, the through hole 12 has been seted up on the board oar 11, and stirring in-process liquid passes through hole 12 and is equivalent to obtaining an acceleration to form the turbulent flow in the cauldron body 1, thereby accelerate the stirring all. In this embodiment, the stirring rod 3 is in a chevron shape, and the length of the connecting rod 10 is smaller than the transverse width of the stirring rod 3, so that the whole formed by the sleeve 9, the connecting rod 10 and the plate paddle 11 can be screwed into the stirring rod 3, that is, the movable paddle is located in the stirring paddle 3 after descending to the bottom, and the structural schematic diagram thereof can be referred to fig. 2. The rapid feeding port 8 is formed in the kettle cover 2, so that the kettle cover 2 is prevented from being opened to feed materials, and the operation procedures are shortened. In order to protect the liquid seal bearing 5, the kettle cover 2 is provided with a shield 7 outside the liquid seal bearing 5. Finally, in order to clean the plate paddles 11 to clean the through holes 12 on the plate paddles 11, the plate paddles 11 are connected with the connecting rod 10 through threads, so that the disassembly is convenient.
