This invention relates to the field of activated carbon production technology and discloses an integrated carbon activation furnace for coal-based activated carbon production. The furnace includes a heating and preheating chamber and a first heating and carbonization chamber located at the bottom end of the heating and preheating chamber. A second heating and carbonization chamber is fixedly installed on the side of the first heating and carbonization chamber facing away from the heating and preheating chamber. A drying and carbonization chamber is fixedly installed on the side of the second heating and carbonization chamber facing away from the first heating and carbonization chamber. A multi-stage coupling is rotatably installed on the side of the heating and preheating chamber facing away from the drying and carbonization chamber. The end of the multi-stage coupling passes through both the first and second heating and carbonization chambers. This invention effectively avoids the defects of traditional structures, such as insufficient material contact with the activator, low material guiding efficiency, and easy agglomeration and coking.

This utility model relates to the field of spectrum analyzers, specifically a portable spectrum analyzer for electrical instruments. It includes a spectrum analyzer body, which comprises a housing. A wiring port body is fixedly connected to the bottom front side of the housing. The utility model involves inserting a connecting cable body into the surface of the wiring port body, then rotating an anti-disengagement cover. With the anti-disengagement cover threadedly connected to the wiring port body, it moves forward, causing a positioning block to engage with the arc-shaped groove, thus positioning the connecting cable body. Simultaneously, the anti-disengagement cover covers the surface of the connecting cable body, further securing the connection between the connecting cable body and the wiring port body, achieving an anti-disengagement effect. This solves the problem that repeated insertion and removal over a long period can easily lead to loosening between the wiring port and the connecting cable, and even the problem of the inserted connecting cable easily detaching from the interface.

This invention provides a transnasal interventional variable stiffness flexible bone-grinding robot and a stiffness control method, comprising a grinding mechanism, an inner arm drive mechanism, and an outer arm drive mechanism. The outer arm continuum of this application is composed of snake bone continuum units, which enable it to have both high flexibility and high stiffness. After the outer arm continuum enters the surgical cavity, it can provide a high-stiffness working space for the inner arm continuum and the drill bit. By simultaneously axially stretching / compressing the tendon, the compression or extension of the distal spring of the inner arm continuum can be controlled, thereby changing the stiffness of the distal end of the inner arm continuum. When feeding, the spring is stretched to reduce stiffness, making it more flexible and conducive to reaching the surgical area. When the grinding drill bit is working, the spring is compressed, making it have high stiffness so that it does not damage non-disease tissue when the drill bit grinds bone, realizing the function of adjustable stiffness, which is more conducive to the needs of surgical operation.
