Embodiment 1

[0018] See also Fig. 2, have provided the kettle body 1 that specific structure, concrete material and specification are not limited by illustration, in kettle body 1, be provided with agitator 2, this agitator 2 comprises agitator shaft 21 and agitator paddle 22, agitator The material of the shaft 21 and the stirring paddle 22 can be metal or enamel without limitation, wherein: the stirring paddle 22 is fixed on the lower end of the stirring shaft 21, and the upper end of the stirring shaft 21 is connected to the top of the kettle body 1 through the bearing 211. The central connection of the wall 11 enables the stirring shaft 21 and the stirring paddle 22 to pivot and rotatably connect to the top wall 11 in the form of a cantilever. Stirring shaft 21 protrudes (stretches out) the end portion outside the bearing 211 and is not shown in the figure but belongs to the driving device transmission connection of known category, in the present embodiment, by motor as driving device. ...

Embodiment 2

[0021] Only the umbrella body 31 is replaced by three pieces (layers) of felts with a thickness of 2mm, and the distance between the mouth of the horn body 311 on the upper part of the umbrella body 31 and the top wall 11 is changed to 18cm, and the rest are implemented in the same way. Description of Example 1.

Embodiment 3

[0023] Only change the umbrella body 31 to be composed of five pieces (layers) of felts with a thickness of 1.5mm, and change the distance between the mouth of the horn body 311 on the upper part of the umbrella body 31 and the top wall 11 to 15cm, and implement the same for the rest. Description of Example 1.

Abstract

A reaction kettle is the modification of a reaction kettle structure in prior art, which comprises a kettle body and a stirring device. The stirring device comprises a stirring shaft and a stirring paddle. The stirring paddle is fixed at the lower end of the stirring shaft. The upper end of the stirring shaft is pivotedly disposed on the top wall of the kettle body through a bearing in a cantilever manner. The top portion of the stirring shaft extending out of the bearing is connected with a driving device in a transmission manner. The reaction kettle is characterized in that a deposition umbrella for accommodating the generated dirt due to bearing abrasion is disposed at the upper part of the shaft body of the stirring shaft in the kettle body. The reaction kettle has the advantages that owing to the deposition umbrella disposed on the stirring shaft, dirt generated due to bearing abrasion can be deposited in the deposition umbrella, so that the dirt is prevented from falling into the material in the kettle body to ensure the acquirement of high-purity fine chemical products.

Description

technical field [0001] The invention relates to a reactor, which is an improvement on the structure of the reactor in the prior art. Background technique [0002] The structure of the reactor in the prior art is shown in Fig. 1, comprises kettle body 1 and stirring device 2, and stirring device 2 comprises stirring shaft 21 and stirring paddle 22, and stirring paddle 22 is fixed on the lower end of stirring shaft 21, and stirring shaft The upper end of the stirring shaft 21 is pivoted on the top wall 11 of the kettle body 1 in a cantilever form through the bearing 211, and the upper end of the stirring shaft 21 protruding out of the bearing 211 is connected with the power drive device in transmission. Reactors with this structure are widely used in the production of chemical, pharmaceutical products, dye intermediates, etc., and their functions and working principles are well known. When the materials in the kettle body 1 need to be stirred, the motor as a driving device dr...
