Abstract
The utility model relates to a water -reducing agent processing equipment field, concretely relates to ester class polycarboxylate water reducing agent polymerization cauldron, its characterized in that: the discharge gate orientation of inlet pipe the stirring rake. The utility model has the advantages that: simple structure, the practicality is strong, can effectively prevent to esterify the material when the dropwise add on reactor inner wall autohemagglutination caking to guarantee the monomer reaction totally, product quality is stable.
Description
Technical field
The utility model relates to water reducer processing units field, is specifically related to ester class polycarboxylate water-reducer polymerization reaction kettle.
Background technology
The synthesis of ester class polycarboxylate water-reducer is divided into two steps, and the first step is esterification, and MPEG and methacrylated obtain esterification material; Second step is the polyreaction of esterification material and methacrylic acid, obtains the polymkeric substance of specified molecular weight.In the polymerization; general temperature is at 80-100 degree; often have partial esterification material in the esterification gob added-time to stay along reactor inwall; because in kettle, vapor temperature is high; make esterification material also not enter bed material produce autohemagglutination and lump, be bonded on reactor inwall, have impact on quality product; product performance can be caused time serious to lose efficacy, cause financial loss.
Summary of the invention
The purpose of this utility model is according to above-mentioned the deficiencies in the prior art, provide ester class polycarboxylate water-reducer polymerization reaction kettle, by the feed-pipe that opening is arranged to side, stirring rake direction, effectively prevent esterification material drip time on reactor inwall autohemagglutination caking, thus bonding precursor reactant is complete, constant product quality.
The utility model object realizes being completed by following technical scheme:
A kind of ester class polycarboxylate water-reducer polymerization reaction kettle, comprise kettle, stirring rake, feed-pipe, stirrer, it is inner that described stirring rake is arranged on described kettle, described stirring rake connects driving by described stirrer, described feed-pipe to be arranged on described kettle and to be communicated with its Inner Constitution, it is characterized in that: the discharge port of described feed-pipe is towards described stirring rake.
The discharge port of described feed-pipe refers to towards described stirring rake, and the body local of described feed-pipe is in curved arrangement, and its bending direction, towards described stirring rake, makes the discharge port of described feed-pipe towards described stirring rake.
Described feed-pipe comprises two pipeline sections, arranges, be satisfied with and make the angle between the discharge port of described feed-pipe and described stirring rake be 45 ° between two pipeline sections in angle.
Described kettle is provided with some described feed-pipes, some feed-pipes are centrosymmetric to distribute and arrange.
The utility model has the advantages that: structure is simple, practical, can effectively prevent esterification material when dripping on reactor inwall autohemagglutination caking, thus bonding precursor reactant is complete, constant product quality.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1.
Embodiment
The utility model feature and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that the understanding of technician of the same trade:
As shown in Figure 1-2, mark 1-7 in figure to be respectively: kettle 1, stirrer 2, stirring rake 3, feed-pipe 4, pipeline section 5, pipeline section 6, discharge port 7.
Embodiment: as shown in Figure 1, the ester class polycarboxylate water-reducer polymerization reaction kettle in the present embodiment comprises kettle 1, stirrer 2, stirring rake 3 and feed-pipe 4.Stirring rake 3 is arranged on the inside of kettle 1, for stirring raw material.Stirrer 2 is arranged on the outside of kettle 1, consists of and is in transmission connection, make stirrer 2 by drive shaft stirring rake 3 in kettle 1 inner rotation drive shaft and stirring rake 3.Feed-pipe 4 is arranged on the top of kettle 1, and its pore is communicated with the Inner Constitution of kettle 1, to be transported among kettle 1 by the discharge port 7 of raw material from feed-pipe 4.
Be provided with on the top of kettle 1 three feed-pipes, 4, three feed-pipes 4 be centrosymmetric distribution arrange.Every root feed-pipe 4 all has pipeline section 5 and pipeline section 6, arrange in angle between pipeline section 5 and pipeline section 6, be satisfied with and make discharge port 7 towards stirring rake 4, so, can ensure that esterification material directly enters among bed material in dropping process, can not stick on the inwall of kettle 1.
The present embodiment is in the specific implementation: the angle between pipeline section 5 and pipeline section 6, also be satisfied with and make the angle between the discharge port 7 of feed-pipe 4 and stirring rake 3 be 45 °, so, except on the inwall adhering to kettle 1 except avoiding esterification material in dropping process, can also ensure that esterification material is directly added drop-wise within the scope of the stirring of stirring rake 3, improve it and bed material can react completely.
Although above embodiment elaborates the design of the utility model object and embodiment with reference to accompanying drawing, but those of ordinary skill in the art can recognize, under the precondition not departing from claim limited range, still various improvement and conversion can be made to the utility model, as: the concrete structure of stirring rake 3, the type of drive etc. of stirrer 2, therefore do not repeat one by one at this.
