This invention relates to an asymmetric catalytic composite membrane and its preparation method, belonging to the field of chemical catalytic separation technology. The catalytic composite membrane adopts a three-layer asymmetric composite structure, consisting of a catalytic layer, an intermediate support layer, and a separation layer. The intermediate support layer is placed between the catalytic layer and the separation layer to achieve physical isolation between the two layers, avoiding damage to the separation layer structure during the catalytic layer preparation process. Specifically, the catalytic layer is a sulfonated polyvinyl alcohol (PVA) membrane with a porous structure prepared by freeze-drying technology. After sulfonation modification and freeze-drying to create pores, it exhibits both low mass transfer resistance and high catalytic activity. The intermediate support layer is a polyacrylonitrile (PAN) ultrafiltration membrane, providing stability and isolation. The separation layer is a dense membrane formed by spin-coating MOF-801 nanoparticles with sodium alginate (SA). The hydrophilic MOF-801 nanoparticles significantly improve the water / ethanol separation efficiency. The asymmetric structure of this invention has the characteristic of independent optimization of functional layers, which can enhance the performance of the catalytic layer and the separation layer respectively. The prepared sulfonated polyvinyl alcohol (PVA) catalytic composite membrane exhibits excellent catalytic-separation coupling performance and long-term stability in esterification reaction, and has good prospects for industrial application.

This utility model relates to the field of cleaning equipment technology and discloses an ultrasonic cleaner with a rotating basket. The cleaner includes a machine body, a roller rotatably connected to the surface of the machine body, and a fixed rod connected to the surface of the machine body. The arc surface of the fixed rod is rotatably connected to the roller, and a flattening device is provided on the arc surface of the fixed rod. The flattening device includes two hollow tubes, both of which are fixedly connected to the arc surface of the fixed rod.

This utility model belongs to the field of refrigeration component drying technology, specifically a refrigeration component drying device, including a drying chamber. An electric motor is installed on the top side of the drying chamber, and the output end of the electric motor is connected to a rotating column. The bottom end of the rotating column is rotatably mounted on the inner wall of the bottom of the drying chamber. Four support rods are fixed on the rotating column, and each support rod has a placement tray rotatably mounted at both ends. Each placement tray has multiple ventilation holes. When drying refrigeration components, this utility model uses the rotation and self-rotation of the placement trays to continuously change the position and angle of the refrigeration components during the drying process, avoiding localized overheating or uneven drying. This ensures that each refrigeration component is evenly exposed to the hot airflow, thereby achieving uniform and comprehensive drying and greatly improving the drying effect.

This utility model discloses a disinfection device for domestic water, relating to the technical field of domestic water disinfection devices. It includes an outer shell assembly composed of a stainless steel cylinder, a flange, and a connecting channel. Disinfection components are disposed on the inner and outer sides of the stainless steel cylinder, and these components are used to disinfect the water flowing through the inner side of the stainless steel cylinder. This utility model achieves water flow along a spiral trajectory and is disinfected by ultraviolet radiation by setting up the disinfection components. Compared to traditional straight flow, the spiral flow extends the water flow distance, increasing the exposure time for microorganisms. Furthermore, the centrifugal force generated by the swirling flow causes repeated exchange of water from the pipe wall to the center, allowing microorganisms to be more evenly exposed to the high-intensity ultraviolet radiation area. This reduces radiation dead zones, extends exposure time, and increases the probability of microorganisms contacting ultraviolet radiation, further improving the disinfection effect and power of domestic water.
