Description

Reaction kettle for production of soldering flux

Technical Field

The utility model relates to a reation kettle is used in scaling powder production.

Background

The raw materials of the soldering flux contain a foaming agent, and the foaming agent is specifically any one of n-pentane, petroleum ether and fatty alcohol-polyoxyethylene ether sodium sulfate. When the foaming agent is mixed with the other raw material rosin of the scaling powder, bubbles are formed in the mixed solution, the foaming agent can effectively reduce the surface tension of the basic solvent, the double electronic layers are arranged on the surface of the liquid film to surround air to form the bubbles, and then the bubbles form foams, so that the mixing efficiency of the synthetic surfactant and the acid solution is improved, and the active agent is prevented from being removed from the mixed solvent of the basic rosin. Therefore, the bubbles can increase the dissolution rate of the activator, promote the dissolution rate between the activator and the rosin mixed liquid, prevent solid components such as the activator from being dissolved out of the solution, and avoid poor non-uniform distribution of the activator. Therefore, the foaming agent is helpful for improving the product quality of the soldering flux. The soldering flux is prepared in a mode of stirring uniformly. After the bubbles in the mixed liquid are generated, the bubbles with small volume are polymerized into bubbles with larger volume by stirring, so that the condition that the bubbles in the mixed liquid are not uniformly distributed is caused. As mentioned above, the bubbles have a positive effect on improving the quality of the flux, and if the bubbles are not uniformly distributed, the flux cannot be efficiently mixed.

Because the surface of support is the rotation direction of operation face and stirring rake I is perpendicular, the surface that only has the spoiler is the rotation direction slope of operation face and stirring rake I for stirring rake I moves with slower speed of motion among this technical scheme, the support disturbance produces the vortex of I rotation direction upper symmetry in the stirring rake in the mixed liquid, and the spoiler then produces decurrent vortex in mixed liquid, the vortex of two kinds of modes guides mixed liquid and forms from the top down mode of flow in the barrel, impels mixed liquid constantly to flow and mix towards the barrel bottom. This operation mode can avoid stirring rake I to form the shearing force to the bubble, and then avoids destroying the tension on bubble surface for the bubble in the mixed liquid keeps the original shape all the time, and the difficult gathering of bubble forms bulky bubble.

In order to solve the problem of stirring dead angle, this technical scheme has set up the scraper blade. The working area of the scrapers is located at the position of the gap, so that the mixed liquor in the gap is disturbed by the scrapers and moves along with downward disturbed flow. The scraping plates are distributed on two sides of the support, the scraping plates on the two sides of the support are in a staggered distribution position relation, and the scraping plates are arranged on the edge folding part on one side of the support. The technical characteristics of the staggered distribution of the scrapers can ensure that the stirring effect is improved in a small operation area and a short stirring stroke.
