Description

Technical Field

[0001] The utility model relates to the technical field of washing and processing for preparing conductive silver powder, in particular to a stirring device for washing conductive silver powder. Background Technique

[0002] Washing and processing is an indispensable process in the chemical liquid-phase reduction method for processing silver powder. After the silver powder slurry is filtered by a corresponding suction filtration device, it is then put into a corresponding washing tank and stirred and washed with a washing liquid; the washed material is filtered and then a surface modifier is added, and the material is stirred and dispersed; then the modified material is pumped and discharged to a corresponding solid-liquid separation device for solid-liquid separation processing.

[0003] In order to ensure sufficient mixing effect of the material during the washing process, generally, it is required that the stirring blades of the stirring device have a sufficient stirring area; and in order to ensure sufficient dispersion kinetic energy of the material during the dispersion process, it is often required that the stirring area of the stirring blades of the stirring device is small and the stirring speed is high. Therefore, two sets of stirring devices need to be configured to separately handle the washing and stirring and the dispersion stirring of the material. In this way, not only the processing efficiency is affected, but also the production cost is increased.

[0004] Therefore, the research purpose of the utility model is to design a stirring device for washing conductive silver powder with adjustable stirring area and speed, so as to be adaptable to wash and stir the material and disperse and stir the material. Summary of the Invention

[0005] Aiming at the technical problems existing in the above-mentioned prior art, the utility model provides a stirring device for washing conductive silver powder, which can effectively solve the technical problems existing in the above-mentioned prior art.

[0006] The technical solution of the utility model is as follows:

[0007] A stirring device for washing conductive silver powder, comprising:

[0008] A stirring shaft, rotatably installed in a corresponding washing tank body, and the stirring shaft is driven by a driving motor fixedly installed on the top of the washing tank body;

[0009] A plurality of stirring blades, evenly distributed and connected to the stirring shaft, and the stirring blades are respectively rotatably installed on the stirring shaft through insertion shafts fixedly connected to the lower sides of the middle parts of the stirring blades;

[0010] A number of gear rods are respectively fixedly connected to the stirring shaft on the back side of the stirring blade. The top surface of the gear rod is arranged in an inclined plane shape, and the driving motor is a forward and reverse adjustable speed motor. When the stirring shaft starts to rotate in reverse, the upper part of the stirring blade is pushed upward by the material and then flips upward. The lower side of the stirring blade abuts against the side of the gear rod to vertically stir the material. When the stirring shaft starts to rotate forward, the upper part of the stirring blade is pushed downward by the material and then flips downward. The upper part of the stirring blade is inclined and abuts against the top surface of the gear rod.

[0011] The stirring blade is arranged in a square plate shape.

[0012] A number of corresponding dispersing rods are uniformly and upwardly fixedly connected to the front side of the stirring blade. When the upper part of the stirring blade is inclined and abuts against the top surface of the gear rod, the dispersing rods are arranged upward.

[0013] The speed when the stirring shaft starts to rotate forward is greater than the speed when the stirring shaft starts to rotate in reverse.

[0014] The inclination angle of the top surface of the gear rod does not exceed 30°.

[0015] Push rods and pull rods are fixedly connected to the upper part of the stirring shaft at intervals in a staggered manner. The length of the push rod is greater than the length of the pull rod, and the ends of the pull rods are respectively fixedly connected with corresponding magnets.

[0016] Advantages of the present utility model:

[0017] 1) By respectively arranging gear rods on the stirring shaft on the back side of the stirring blade, when the stirring shaft starts to rotate in reverse, the upper part of the stirring blade is pushed upward by the material and then flips upward. The lower side of the stirring blade abuts against the side of the gear rod to vertically stir the material, thereby ensuring that the stirring blade has a sufficient stirring area for the material to improve the stirring effect on the material. When the stirring shaft starts to rotate forward, the upper part of the stirring blade is pushed downward by the material and then flips downward. The upper part of the stirring blade is inclined and abuts against the top surface of the gear rod to reduce the stirring area. Then, by increasing the stirring speed, the material can be effectively and fully dispersed, enabling the material to come into full contact with the surface modifier under the dispersion action. Thus, the material can be effectively washed and stirred, and dispersed and modified, so as to improve the processing efficiency and reduce the production cost.

[0018] 2) The present utility model further uniformly and upwardly fixedly connects a number of dispersing rods to the front side of the stirring blade. When the upper part of the stirring blade is inclined and abuts against the top surface of the gear rod, the dispersing rods are arranged upward. Under the action of the dispersing rods, the dispersion effect of the present utility model on the material can be further improved.

[0019] 3) On the upper part of the stirring shaft of the present utility model, push rods and pull rods are fixedly connected at intervals in a staggered manner. The length of the push rods is greater than that of the pull rods, and magnets are fixedly connected to the end parts of the pull rods respectively. As the stirring shaft rotates, the push rods and pull rods can alternately push and reset and adsorb a pressure filter piston arranged on the upper part of the washing tank body, so as to perform a pressure filtration operation on the materials in a fixed container located on the upper part of the washing tank body, thereby enhancing the use function of the present utility model.
