High-performance reaction kettle special for conductive slurry production

Abstract

A special high-performance reactor for the production of conductive paste. The reactor housing is equipped with a motor, a stirring shaft, a feed inlet, a discharge outlet and support feet; the motor is fixed on the highest point of the top center of the reactor housing by bolts, The bottom is connected to the stirring shaft, and the stirring shaft is provided with a first stirring rod, a second stirring rod, a third stirring rod and a stirring bottom plate; each second stirring rod is provided with two arc rods and four first blades; The number of the first stirring rod is two. The first stirring rod is inclined on the stirring shaft, and the second blade is arranged on one side of the first stirring rod; the number of the third stirring rod is two, and the third stirring rod and the first stirring rod On the stirring shaft, the second stirring rod is used as the symmetrical axis, and it is arranged in axisymmetric manner; the shape of the stirring bottom plate is a right-angled triangle structure; the spherical reactor shell adopts a special stirring rod and a variety of blades to carry out mixing in all directions and from multiple angles. Avoid uneven distribution of the upper and lower slurry, and improve the use effect.

Description

technical field [0001] The invention relates to a special high-performance reaction kettle for producing conductive paste. Background technique [0002] As a renewable new energy source, solar energy has the advantages of cleanness, large reserves, and easy access. The electrical properties of the metal electronic paste printed on the surface of the solar cell silicon plate are an important factor affecting the photoelectric conversion rate. The conductive paste has metal Powder and glass powder are prepared by dispersing in an organic carrier. The telecommunications parameters, particle size distribution, and dispersion of metal particles in the conductive paste will affect the overall performance of the photovoltaic cell. In the prior art, silver powder is mainly used as the conductive paste Affected by the equipment and process, when the raw materials are mixed and reacted in the reactor, there are likely to be large aggregates in the slurry of the semi-finished product, ...
