Description

A chemical cooling mixing tube

technical field

The invention relates to a chemical liquid mixing device, in particular to a chemical cooling mixing tube.

Background technique

In chemical production, it is often encountered that two or more fluids need to be mixed. Usually, the mixing tank is used to achieve the purpose of mixing. However, the mixing tank is difficult to mix continuously, and the process is complicated. It is suitable for existing industrialized continuous production.

In addition, chemical fluids are often accompanied by a large amount of exothermic heat when they are mixed and reacted. Therefore, how to quickly and uniformly cool down is the key point that must be considered.

Contents of the invention

The object of the present invention is to provide a cooling mixing tube for chemical industry to solve the problems raised in the above-mentioned background technology.

To achieve the above object, the present invention provides the following technical solutions:

A chemical cooling mixing tube, comprising an inner tube for the circulation of the mixed liquid, the inner tube is covered with an outer tube, the inner tube is made of heat-conducting material, and the outer tube is made of heat-insulating material; There are multiple groups of mixing units arranged in the inner tube along the traveling direction of the inner tube. The mixing units include three triangular tube wall blades formed by cutting the cylinder, and each group of triangular tube wall blades is evenly distributed on the inner wall of the inner tube at 120°; The triangular tube wall vanes are left-handed, the arc-shaped bottom edges of the triangular tube wall vanes are all set towards the front side of the inner tube, the apexes of the triangular tube wall vanes are all set towards the rear side of the inner tube, and the triangular tube wall vanes are all set towards the rear side of the inner tube. There are a plurality of spoiler holes passing through its two sides; adjacent triangular tube wall blades are provided with cooling fins in the opposite direction of rotation, and the cooling fins pass through the inner tube and are fixedly connected to the inner wall of the outer tube; The gap between the outer tube and the inner tube constitutes a cooling passage for cooling gas or cooling liquid to circulate.

As a further solution of the present invention: the length of the arc-shaped base is 0.2 times the circumference of the inner tube.

Compared with the prior art, the beneficial effect of the present invention is: when in use, the mixed liquid flows from front to rear along the inner wall of the inner cylinder, and under the action of the triangular tube wall vanes, the mixed liquid forms three incompletely cut-off channels. The fluid area is moved forward through the small spiral vortex, and the mixing effect is good; the spoiler hole can introduce the liquid on one side of the triangular tube wall vane into the other side for collision and mixing, further improving the mixing effect; The cooling fins on the opposite side improve the efficiency of separation, rotation and confluence of the mixed liquid, and further improve the mixing effect, and the cooling fins extend into the mixed liquid, increasing the contact area with the mixed liquid and improving the cooling of the gas into the cooling channel. Or the heat transfer efficiency of the cooling liquid, and then realize the rapid cooling of the mixed liquid, and the extension of the heat sink into the mixed liquid can also avoid the situation of "cold outside and hot inside" when the mixed liquid is cooling down.

To sum up, the present invention has a simple and reasonable structure, is easy to use, completes the rapid mixing of the mixed liquid while conveying, reduces the mixing process, improves production efficiency, and at the same time realizes rapid and uniform cooling of the mixed liquid, which facilitates the realization of industrialized continuous production.

detailed description

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Please refer to Fig. 1, a cooling mixing tube for chemical industry, comprising an inner tube 2 for the circulation of the mixed liquid, the inner tube 2 is sheathed with an outer tube 1, the inner tube 2 is made of a heat-conducting material, and the outer tube 1 is made of thermal insulation material; the inner tube 2 is provided with multiple groups of mixing units along the direction of travel of the inner tube 2, and the mixing unit includes three triangular tube wall blades 4 formed by cutting the cylinder, and each group of triangular tubes The wall vanes 4 are uniformly distributed on the inner wall of the inner tube 2 at 120°; the triangular tube wall vanes 4 are left-handed, and the arc-shaped bottom edges 7 of the triangular tube wall vanes 4 are all arranged towards the front side of the inner tube 2. The vertices of the triangular tube wall blades 4 are all arranged towards the rear side of the inner tube 2, and the triangular tube wall blades 4 are provided with a plurality of spoiler holes 5 passing through both sides thereof; There are cooling fins 6 in the opposite direction of rotation, and the cooling fins 6 pass through the inner tube 2 and are fixedly connected to the inner wall of the outer tube 1; the gap between the outer tube 1 and the inner tube 2 constitutes a cooling gas or cooling liquid circulation Cooling channel 3.

The working principle of the present invention is: when in use, the mixed liquid flows from front to rear along the inner wall of the inner tube 2, and under the action of the triangular tube wall vanes 4, the mixed liquid forms three fluid regions that are not completely interrupted, and passes through The small spiral vortex moves forward, and the mixing effect is good; the spoiler hole 5 can introduce the liquid on one side of the triangular tube wall blade 4 into the other side for collision and mixing, further improving the mixing effect; The heat sink 6 improves the efficiency of the separation, rotation and confluence of the mixed liquid, and further improves the mixing effect, and the heat sink 6 extends into the mixed liquid, which increases the contact area with the mixed liquid and improves its cooling into the cooling channel 3. The heat transfer efficiency of the gas or cooling liquid can realize the rapid cooling of the mixed liquid, and the extension of the heat sink 6 into the mixed liquid can also avoid the situation of "cold outside and hot inside" when the mixed liquid is cooling down.
