Abstract
The utility model relates to a stirring device of a crystallization reaction kettle, for solving the crystallization deposition problem at the bottom of the kettle. The stirring device of the crystallization reaction kettle disclosed by the utility model is composed of a kettle body and a stirrer installed in the kettle body, and is characterized in that the stirrer is of a combined structure and comprises a stirring shaft; a stirring frame is arranged at the lower part of the stirring shaft; a plurality of stirring rake teeth extending towards the bottom of the kettle body are arranged at a bottom frame of the stirring frame. According to the utility model, the stirring rake teeth are arranged on the bottom frame of the stirring frame of the frame type stirrer; in the event of not greatly increasing the stirring load, the problem of depositing crystals at the bottom of a crystallization material kettle is thoroughly solved by controlling the clearance between the bottom end of the stirring rake teeth and the bottom of the kettle body; by adopting the stirring device of the crystallization reaction kettle, uniform stirring can be ensured; materials cannot be deposited at the bottom in the crystallization reaction process; crystals are sufficiently contacted with solution; the reaction speed is increased; the reaction time is reduced; furthermore, because kettle body deposition is eliminated, the kettle body is uniform for heat transmission and high in heat transmission efficiency; in addition, discharging is smooth.
Description
Technical field
The utility model relates to a kind of chemical industry equipment, especially crystal class stirring apparatus for reaction kettle.
Background technology
Crystallization reaction still is chemical industry common equipment, and crystallization reaction still is provided with agitator, and agitator has effects such as reaching the material that is mixed, increase heat transfer, promotion reaction speed.Standard gate stirrer is a kind of agitator that crystal class reactor is conventional, and gate stirrer comprises shaft and the agitator frame by shaft driven rotary, and its structure as shown in Figure 3.Standard gate stirrer because of consider to stir load when rocking easily and the problem such as kettle collision, friction, at the bottom of designed stirring frame bottom and still, distance is larger, generally about 80-110mm, and crystalline solid easily deposits in bottom, cause like this that there are the following problems in crystallization whipping process: 1, depositing crystalline body can not fully contact with solution, greatly reduces reaction speed; 2, have a strong impact on heat transfer coefficient at reactor bottom crystalline solid sedimentary deposit, conduct heat inhomogeneous, heat transfer efficiency is low; 3, the crystalline solid of bottom deposition easily stops up discharging opening affects dispensing speed.
Utility model content
The purpose of this utility model is the drawback for prior art, and fully stirred crystallization type material of one is provided, and thoroughly solves the crystal class stirring apparatus for reaction kettle of crystalline solid still bottom sediments problem.
Problem described in the utility model is by realizing with following technical proposals:
A kind of crystal class stirring apparatus for reaction kettle, it is made up of kettle and the agitator being arranged in kettle, special feature is: described agitator is combining structure, it comprises shaft, bottom at shaft is provided with agitator frame, is provided with several stirring rake teeths that extend to autoclave body bottom at the underframe place of agitator frame.
Above-mentioned crystal class stirring apparatus for reaction kettle, the bottom line of described each stirring rake teeth is camber line, and this camber line mates with the arc at the bottom of reactor still, and the distance B between at the bottom of this camber line and still is 10-12 millimeter.
Above-mentioned crystal class stirring apparatus for reaction kettle, described stirring rake teeth is centered by shaft on the underframe that is distributed in agitator frame symmetrically, distance between adjacent stirring rake teeth is 100-110 millimeter, and the stirring rake teeth position that is positioned at two ends is corresponding with the frame of agitator frame.
Above-mentioned crystal class stirring apparatus for reaction kettle, described stirring rake teeth is tabular, and its width is 45-50 millimeter, and stirring rake teeth is polytetrafluoroethylene (PTFE) material.
The utility model improves for solving the brilliant deposition problems of common crystallization reaction still still bear building-up, has designed a kind of crystal class stirring apparatus for reaction kettle.Described device comprises kettle and agitator, agitator is combined type, on the underframe of gate stirrer agitator frame, be provided with several stirring rake teeths, and the gap of stirring rake teeth bottom and autoclave body bottom by control, in the situation that not rolling up stirring load, thoroughly solve the problem of crystal type material still bottom depositing crystalline body.Adopt the utility model, can guarantee to stir, there is not still bottom sediments in material in still intercrystalline course of reaction, and crystalline solid fully contacts with solution, improves reaction speed and reduced the reaction time.In addition,, owing to having eliminated kettle deposition, kettle heat transfer uniformly transfer heat efficiency is improved, and make blowing smooth and easy.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the A of Fig. 1 is to view;
Fig. 3 is agitating device schematic diagram before improving.
In figure, each list of reference numerals is: 1, motor, 2, decelerator, 3, shaft, 4, stir frame, 5, stir rake teeth, 6, kettle.
The specific embodiment
Referring to Fig. 1, Fig. 2, the utility model is made up of kettle 6 and the agitator being arranged in kettle, and agitator is combining structure, and it comprises shaft 3, is provided with motor 1 on kettle top, and motor drives shaft rotation through decelerator 2.Be provided with agitator frame 4 in the bottom of shaft, be provided with several stirring rake teeths 5 that extend to autoclave body bottom at the underframe place of agitator frame, each bottom line that stirs rake teeth 5 forms camber line, and the arc at the bottom of this camber line and reactor still matches, and the distance B between at the bottom of this camber line and still is 10-12 millimeter.Arrange and stir after rake teeth, shortened distance at the bottom of stirring frame bottom and still, solved the problem of depositing crystalline body bottom crystal type material still.Rock for preventing from stirring, stir rake teeth and select the good polyfluortetraethylene plate of pliability to make.
Referring to Fig. 1, stir rake teeth 5 centered by shaft, on the underframe that is distributed in agitator frame 4 symmetrically, the distance between adjacent stirring rake teeth is 100-110 millimeter, the stirring rake teeth position that is positioned at two ends is corresponding with the frame of agitator frame.It is tabular stirring rake teeth 5, and its width is 45-50 millimeter.
The utility model shows through trial run, and agitator can fully stir the crystallized stock in kettle, particularly can stir the material of dead angle part at the bottom of still, thoroughly solves the drawback that stirs dead angle basic sediment material.
