Description
Technical Field
The present disclosure relates to stirred tanks, and more particularly to an externally forced dispersion apparatus for improving the dispersive mixing capability of a stirred tank.
Background
The stirring kettle is widely applied to the reaction and mixing processing of chemical liquid products. When a stirred tank is used for preparing a product containing insoluble solid powder and incompatible liquid components, the particle size fineness uniformity and the dispersion uniformity of a dispersed phase in a solution are limited. This problem is mainly caused by two reasons, on one hand, the force applied to the dispersed phase by the solution flow caused by the impact of the two dispersed phases in the solution and the rotation of the stirring paddle is often insufficient, and on the other hand, the effective force is difficult to form and effectively act on the dispersed phase directly.

In an example of the disclosure, when powder materials are to be added, the second two-position three-way electromagnetic valve is connected to the feeding device for feeding; when the charging is finished, the second two-position three-way electromagnetic valve is connected to the bypass pipeline to realize further external forced dispersion.

Detailed Description
In order to make the technical solutions of the present disclosure better understood by those of ordinary skill in the art, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings.
It should be noted that the terms "first," "second," and the like in the description and claims of the present disclosure and in the above-described drawings are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the disclosure described herein are capable of operation in sequences other than those illustrated or otherwise described herein. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
As shown in FIG. 1, a stirred tank apparatus equipped with the external forced dispersion apparatus of the present invention is shown.
In the example, a discharge port (serial number 2) is formed in the bottom of the stirring kettle (serial number 1), a two-position three-way electromagnetic valve A (serial number 3) is arranged at the downstream of the discharge port (serial number 2), and switching of two stations of a material discharging and connecting external forced dispersing device can be achieved. When 3-1 bit of the two-position three-way electromagnetic valve A (serial number 3) is communicated, material discharge is realized; when the 3-2 position of the two-position three-way electromagnetic valve A (serial number 3) is connected, the material enters the external forced dispersion device.
In the example, the pump (serial No. 4) is used to provide sufficient power to ensure that the liquid has sufficient power to flow through the various stages downstream of the pump (serial No. 4). The downstream of the pump (serial number 4) is a two-position three-way electromagnetic valve B (serial number 5), which can realize the switching of liquid flowing through the feeding device (serial number 6) and the bypass pipeline (serial number 10). When the two-position three-way electromagnetic valve B (serial number 5) is connected to the 5-1 position, the liquid flows through the Venturi tube (serial number 6-1) of the feeding device. The caliber of the main pipeline of the venturi tube (serial number 6-1) is properly reduced at the position crossed with the auxiliary pipeline, and the flow velocity of fluid flowing through the main pipeline is increased, so that relative low pressure is formed at the pipe orifice of the auxiliary pipeline, and powder materials or incompatible liquid materials in the storage hopper (6-2) are pumped into the main pipeline of the venturi tube (serial number 6-1). An electromagnetic valve (serial number 7) is arranged at the outlet of the feeding device (serial number 6).
In an example, when a two-position three-way electromagnetic valve B (serial number 5) is connected to 5-1 bits, an electromagnetic valve (serial number 7) needs to be in an opening state; when the two-position three-way electromagnetic valve B (serial number 5) is connected to 5-2, the electromagnetic valve (serial number 7) needs to be in a closed state to seal the feeding device (serial number 6). The liquid flowing through the feeding device (serial number 6) carries the powder material or the incompatible liquid material to form a mixed material.
In the example, the mixed materials enter the pipeline sections 8-1 and 8-2 provided with the static mixer (serial number 8), and are crushed and corroded while being subjected to flow splitting and confluence mixing by the static mixer (serial number 8). Different types of static mixers can be used depending on the type of dispersed phase. For the mixing of the insoluble powder material, an SK type static mixer is recommended. For the mixing of incompatible liquid materials, an SX type static mixer is recommended. To facilitate the replacement of the static mixer, the present invention installs the static mixer (No. 8) in a section of pipeline, using a flanged connection for replacement (see fig. 2). In order to improve the mixing effect of the static mixer, the windward side of the mixing blades of the static mixer is processed into a blade shape with an angle of less than 60 degrees, so that the crushing of the dispersed phase is further promoted.
Then, the mixed material flows through a controllable flow distribution valve (serial number 9), one part of the mixed material flows back to the stirring kettle (serial number 1), and the other part of the mixed material enters a storage hopper 6-2 of a feeding device (serial number 6). The mixed material entering the storage hopper 6-2 of the feeding device (serial number 6) plays a role in improving the flowability of the powder material or reducing the relative concentration of the incompatible liquid material, and simultaneously plays a role in cleaning the storage hopper 6-2. When powder materials are to be added, a two-position three-way electromagnetic valve B (serial number 5) is switched on to 5-1 position, and an electromagnetic valve B (serial number 7) is opened for feeding; when the feeding is finished, the two-position three-way electromagnetic valve B (serial number 5) is connected to 5-2, the electromagnetic valve (serial number 7) is closed, and the mixed material continuously flows into the pipeline sections 8-1 and 8-2 provided with the static mixer (serial number 8) through the bypass pipeline (serial number 10), so that further external forced dispersion is realized, and the improvement of dispersion and mixing of the stirring kettle on the insoluble powder material or the incompatible liquid material is facilitated.
By using the external forced dispersion device for improving the dispersive mixing capability of the stirrer, the working state of the stirring kettle is not changed, but the processing time of each kettle can be greatly shortened.
Other embodiments of the disclosure will be apparent to those skilled in the art from consideration of the specification and practice of the disclosure disclosed herein. This application is intended to cover any variations, uses, or adaptations of the disclosure following, in general, the principles of the disclosure and including such departures from the present disclosure as come within known or customary practice within the art to which the disclosure pertains.
