This utility model relates to the fields of food engineering and biotechnology, and discloses an ultrasonic-assisted defrosting device for pet food. It includes a shell, a control screen, a protective door, and a heating component. The control screen is fixedly connected to the surface of the shell, and the protective door is installed on the surface of the shell. The heating component is installed on the inner wall of the shell, and the inner wall of the shell has an installation structure including a sliding groove. A slider is slidably connected to the inner wall of the sliding groove, and a fixing rod is fixedly connected to the inner wall of the sliding groove. The arc surface of the fixing rod is slidably connected to the surface of the slider, and a placement plate is fixedly connected to the surface of the slider. A handle is fixedly connected to the surface of the placement plate. This utility model solves the problem in existing ultrasonic-assisted defrosting devices for pet food where, when the food is placed inside the device, it is often difficult to dry in layers, affecting the degree of drying and thus the working efficiency of the device.

This utility model relates to the field of lithium industry technology and discloses a synthesis reactor for alkyl lithium production, including a reactor body, a discharge port, a feed port, and a motor. The discharge port and feed port are fixedly connected to the surface of the reactor body, and the motor is mounted on the surface of the reactor body. A clamping structure is provided on the surface of the reactor body, including a connecting rod. One end of the connecting rod is fixedly connected to the surface of the reactor body, and the other end is fixedly connected to a connecting plate. A groove is formed on the surface of the connecting plate, and a slider and a bidirectional screw are slidably connected to the inner wall of the groove. This utility model solves the problem that in existing alkyl lithium production synthesis reactors, the discharge port connection often presents difficulties in quick clamping, which over time affects the normal use of the equipment and consequently its operational stability.
