Description

Technical Field

[0001] The utility model relates to the technical field of oxygen sensor chips, in particular to a slurry stirring device for oxygen sensor chips with a dust suction function. Background Art

[0002] In engines that use three-way catalytic converters to reduce exhaust pollution, oxygen sensors are essential components. Oxygen sensors use the Nernst principle, and their core components are porous ZrO2 ceramic tubes, which are solid electrolytes with porous platinum electrodes sintered on both sides. In the production process of oxygen sensor chips, the basic powders for making chips need to be stirred and mixed to form chip substrate cast sheets, and then the electrode layer is printed on the chip substrate cast sheets, and then sintered at high temperature to form oxygen sensor chips. There are many types of slurry stirring devices currently available on the market for oxygen sensor chips, but there are still some disadvantages;

[0003] The existing slurry stirring device has the problem of only improving the stirring efficiency, ignoring the agglomeration of powder when it enters the stirring barrel, and not breaking it up will increase the stirring pressure of the stirring shaft and the stirring blades, which will reduce their service life. At the same time, a large amount of dust will be generated when the powder is stirred, and a large amount of powder will be wasted if the dust is not collected. For example, a Chinese utility model patent with authorization announcement number CN220531332U discloses a slurry stirring device, including a stirring barrel and a stirring mechanism arranged in the stirring barrel, the stirring barrel including a barrel body and a top cover arranged on the barrel body, and the stirring mechanism including a The driving motor on the top cover, the stirring shaft arranged on the output shaft of the driving motor, the stirring blade arranged on the stirring shaft and the clamping assembly arranged between the stirring shaft and the stirring blade, the stirring shaft is arranged in the barrel body, the clamping assembly includes a connecting rod arranged on the stirring shaft and a clamping seat arranged on the stirring blade, the connecting rod is provided with a clamping groove, the clamping seat is provided with a clamping block that can be clamped in the clamping groove, the connecting rod is provided with a clamping ring for fixing the connecting rod and the clamping seat, the clamping ring thread sleeve is arranged on the connecting rod, and the clamping ring thread sleeve is arranged on the clamping seat. The present application has the effect of facilitating the replacement of the kneading blade and improving the stirring efficiency of the slurry. However, this device only improves the stirring efficiency by existing, ignoring the situation that the powder will agglomerate when entering the inside of the stirring barrel, and will not be broken up, which will increase the stirring pressure of the stirring shaft and the stirring blade, etc., and will reduce its service life. At the same time, a large amount of dust will appear when the powder is stirred, and the dust will not be collected, which will waste a large amount of powder. Therefore, we propose a slurry stirring device for oxygen sensor chip with dust collection function to solve the above problems. Utility Model Content
