Solar slurry stirring device

Abstract

The invention provides a solar slurry stirring device. The solar slurry stirring device comprises a stirring barrel, a barrel cover, a spiral lifting pipe, a spiral lifting blade, a central shaft, a rotating disc, a stirring rod, a stirring motor and a driving block, a conical sliding surface is arranged at the bottom of the stirring barrel, a platform surface is arranged at the bottom end of the conical sliding surface, a discharging opening is formed in the middle of the platform surface, a spiral lifting pipe is arranged above the discharging opening, the central shaft is arranged in the spiral lifting pipe, the spiral lifting blade is fixed outside the central shaft, and the top end of the central shaft penetrates out of the barrel cover and is in driving connection with the stirring motor; at least one group of driving blocks are further fixed outside the central shaft, the top end of the rotating disc is rotationally connected to the barrel cover, driving notches used for being matched with the driving blocks in an inserted mode are further formed in the bottom side of the rotating disc, and at least one group of stirring rods located between the spiral lifting pipe and the stirring barrel are further fixed to the bottom side of the rotating disc. The stirring cost is low, the stirring uniformity is better, and precipitated dry powder at dead angles can be better eliminated so that the stirring effect is better.

[0002] Solar electronic paste usually refers to the back silver paste, back aluminum paste and front silver paste for crystalline silicon solar cells. It is a viscous mechanical mixture composed of powder, adhesive, solvent and additives. The slurry is used in the photovoltaic industry; in the solar electronic slurry manufacturing process, a stirring process is required; the stirring equipment in the prior art has low stirring efficiency during the stirring process, and there is sedimentation and dry powder in the vertical dead corner of the side wall, and the stirring effect Bad, uneven dispersion of raw materials and other problems;

[0003] In order to overcome the above defects, a patented stirring device for solar cell sheet printing paste (publication number: CN209271311U) solves the technical problems such as the structure of the existing stirrer is too simple, it is impossible to quickly stir all kinds of raw materials evenly, and the stirring speed is slow. It includes a base, a stirring box is fixed on the base, the upper part of the mixing box has a material inlet, a solenoid valve 1 is arranged at the inlet, the lower part of the mixing box has a discharge port, and a solenoid valve 2 is installed at the discharge port, and the base is fixed. There is a column, and the lifting seat is arranged on the column, and the lifting seat is located directly above the mixing box, the lifting seat is connected with the upper end of the linkage rod, and the lower end of the linkage rod extends into the mixing box and is connected with the positioning frame, and the positioning frame is provided with a stirring mechanism. The lifting seat is also connected with a driving structure that can make it move up and down, so that it has the advantage of fast stirring, but also because of the additional sets of driving parts, the overall equipment cost is high and the structure is relatively complicated
