This invention relates to the field of vapor phase etching (VPE) apparatus technology, specifically a double-sided VPE apparatus for semiconductor silicon wafers. The apparatus includes a VPE apparatus body, a silicon wafer transfer mechanism at the upper end of the apparatus body, an etching chamber fixedly mounted on the outer side of the apparatus body, and a mounting base fixedly mounted on the upper end of the etching chamber. By combining the VPE mechanism with a central air-guiding mechanism, stable adsorption of the semiconductor silicon wafer is ensured during the etching process, avoiding vibration and improving etching efficiency and precision. A Bernoulli-style chuck structure is formed by the cooperation of the air-guiding support stage and the central stage, stably "fixing" the silicon wafer above the air-guiding support stage, minimizing contact with the semiconductor silicon wafer, avoiding physical damage and contamination, and simultaneously enabling multi-directional airflow distribution to meet auxiliary heat dissipation needs for the semiconductor silicon wafer, further improving the accuracy and etching efficiency of the VPE process.

The utility model discloses a kind of anti-clogging cable particle finished product bin, including bin body, bin body is equipped with inner bin body, wherein the discharge port of bin body is lower than the discharge port of inner bin body, further including dredging stirring structure, the dredging stirring structure includes driving device, first stirring structure and second stirring structure.The utility model aims at the problem that double-bin structure is prone to jam in actual use, through the design of dredging stirring structure, the effect of simultaneous dredging inside and outside can be realized, greatly reduce the probability of discharge jam when double-bin structure is used, and the design of the anti-clogging structure will not affect the normal use of the finished product bin.

This utility model discloses a fully luminous spherical lamp, relating to the field of LED lighting technology. It includes a spherical lampshade, an LED light source, a fixing cover, a power cord, and a mounting base. The mounting base is installed on an indoor ceiling. A power cord is connected to the bottom of the mounting base, and a fixing cover is installed at the bottom of the power cord. The LED light source is installed at the bottom of the fixing cover, and screws are installed on the fixing cover. The fixing cover is fixedly connected to the spherical lampshade by the screws. This utility model uses an LED light source composed of polygonal aluminum material and a spherical head. LED beads are embedded in the sides of the polygonal aluminum material, and the spherical head structure is located at the bottom of the polygonal aluminum material. Its length can be adjusted to adapt to different product sizes and power. This design allows light to be evenly scattered from multiple angles, avoiding localized bright spots caused by a single light source position. Combined with the full light transmission characteristics of the spherical lampshade, the light is evenly distributed within the sphere, solving the problem of bright spots appearing in the upper or lower half of the sphere in the prior art.

This utility model relates to the field of microbial fermentation engineering technology, specifically to a solid-state fermentation device for Beauveria bassiana, including a fermentation chamber. A fan and a ventilation pipe are respectively installed at the upper and lower ends of the fermentation chamber. A rotating sleeve is rotatably connected inside the fermentation chamber. A motor is fixedly connected to the bottom of the fermentation chamber, and the output end of the motor is fixedly connected to the bottom end of the rotating sleeve. A cooling and oscillation mechanism periodically lifts the culture tray through a cam to generate oscillation, which, together with the air circulation of the fan and ventilation pipe, enhances the heat exchange between the substrate and the cold air. The spiral stirring blade has a double-layer hollow structure and is connected to the drainage hole to guide the discharge of condensate or cleaning wastewater. At the same time, the hollow structure reduces the temperature of the stirring blade itself and assists in the heat dissipation of the substrate.
