Abstract

An anti-volatilization stirring kettle for preparing TBP tributyl phosphate relates to a stirring kettle, wherein a horn-shaped cover body (5) with a downward small end and an annular glass observation window (4) at the outer edge is covered at an opening of a tank body (13), a rotating shaft (10) driven by a motor (1) extends into the tank body (13) through a through hole (8), a speed reducer (2) is arranged between the motor (1) and the rotating shaft (10), the edge of the bottom of the speed reducer (2) is fixedly connected with the inside of the horn-shaped cover body (5), and a stirring paddle (12) is arranged at the lower end of the rotating shaft (10); the utility model discloses a set up jar body top into the bellmouth shape of microcephaly down to with the edge of speed reducer bottom and the inside rigid coupling of tubaeform lid, realized that the contact department of jar body and pivot has double-deck protection, reached and prevented that reaction solution from to the external volatile purpose.

Description

A stirred tank that volatilizees for preparing TBP tributyl phosphate

Technical Field

The utility model relates to a stirred tank especially relates to a stirred tank prevents volatilizing for preparing TBP tributyl phosphate.

Background

TBP tributyl phosphate extractant is used as solvent, and is also commonly used as plasticizer of nitrocellulose, cellulose acetate, chlorinated rubber and polyvinyl chloride, extractant of rare metals, etc., heat exchange medium. Because of its low surface tension and water-insoluble physical properties, it is effective as an industrial defoaming agent for rapidly defoaming a formed foam film in an unstable state. The top of a traditional stirring kettle is generally in a convex type, and reaction solution in the stirring kettle is easy to volatilize from a joint of the stirring kettle and a rotating shaft, so that not only is the environment pollution easily caused, but also the outside air is caused to enter, and the product purity is reduced.

Disclosure of Invention

In order to overcome not enough among the background art, the utility model discloses a stirred tank prevents volatilizing for preparing TBP tributyl phosphate sets up to little end horn mouth shape down through jar body top to with the inside rigid coupling of the edge of speed reducer bottom and horn shape lid, realized that the contact department of jar body and pivot has double-deck protection, reached and prevented that reaction solution is to external volatile purpose.

In order to realize the purpose, the utility model adopts the following technical scheme:

the utility model provides a stirred tank prevents volatilizing for preparing TBP tributyl phosphate, which comprises a tank body, at the internal upper portion open-ended cavity that is equipped with of jar, the opening part of the jar body is covered with the trumpet-shaped lid that the microcephaly is down and the outer fringe is annular glass observation window, be equipped with the toper chamber in the trumpet-shaped lid, be equipped with the perforation in the bottom of trumpet-shaped lid, motor drive's pivot is stretched into jar internal by the perforation, be equipped with the speed reducer between motor and pivot, the inside rigid coupling of the edge of speed reducer bottom and trumpet-shaped lid, be equipped with the stirring rake at the lower extreme of pivot.

The volatilization prevention stirring kettle for preparing TBP tributyl phosphate is characterized in that a feeding hole is formed in the upper end of the side wall of the tank body.

A stirred tank for preparing preventing volatilizing of TBP tributyl phosphate put the discharge gate in jar central point of body bottom.

The volatilization prevention stirring kettle for preparing TBP tributyl phosphate is characterized in that a power line is arranged on a motor, and a plug is arranged at the end part of the power line.

Since the technical scheme is used, the utility model discloses following beneficial effect has:

the anti-volatilization stirring kettle for preparing TBP tributyl phosphate realizes double-layer protection at the contact part of the tank body and the rotating shaft by setting the top of the tank body into a horn-shaped shape with the small end facing downwards and fixedly connecting the edge of the bottom of the speed reducer with the inside of the horn-shaped cover body, thereby achieving the purpose of preventing reaction solution from volatilizing to the outside; the utility model has the advantages of simple structure and reasonable design, environmental protection is effectual, and market prospect is wide.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

In the figure: 1. a motor; 2. a speed reducer; 3. a feed inlet; 4. an annular glass viewing window; 5. a horn-shaped cover body; 6. a tapered cavity; 7. a power line; 8. perforating; 9. a plug; 10. a rotating shaft; 11. a cavity; 12. a stirring paddle; 13. a tank body; 14. and (4) a discharge port.

Detailed Description

The present invention will be explained in more detail by the following examples, which are not intended to limit the invention, and the purpose of disclosing the invention is to protect all the changes and improvements that come within the scope of the invention;

combine figure 1 a stirred tank for preparing TBP tributyl phosphate prevents volatilizing for preparing, including a jar body 13, be equipped with upper portion open-ended cavity 11 in jar body 13, be equipped with feed inlet 3 in the upper end of jar body 13 lateral wall, central point in jar body 13 bottom puts and is equipped with discharge gate 14, the opening part of jar body 13 is covered with little head down and the outer fringe is tubaeform lid 5 of annular glass observation window 4, be equipped with toper chamber 6 in tubaeform lid 5, be equipped with perforation 8 in tubaeform lid 5's bottom, motor 1 driven pivot 10 stretches into jar body 13 by perforation 8, be equipped with speed reducer 2 between motor 1 and pivot 10, the edge of speed reducer 2 bottom and the inside rigid coupling of tubaeform lid 5, be equipped with stirring rake 12 at the lower extreme of pivot 10, be equipped with power cord 7 on motor 1, tip at power cord 7 is equipped with plug 9.

Implement a stirred tank prevents volatilizing for preparing TBP tributyl phosphate, during the use, with plug 9 switch on, it is rotatory that motor 1 starts drive pivot 10, because contact department of tubaeform lid 5 and pivot 10 is located jar body 13 top and is equipped with tubaeform lid 5's lower, volatile reaction solution is difficult to volatilize to the external world from tubaeform lid 5 and pivot 10's contact department in jar body 13, because the edge of 2 bottoms of speed reducer and tubaeform lid 5's inside rigid coupling again, give in other words tubaeform lid 5 and pivot 10 between the secondary protection, reached and prevented that reaction solution from to the external volatile purpose.

The part of the utility model not detailed is prior art.
