Abstract
Description
Technical Field
[0001] The utility model relates to an activated carbon test furnace, in particular to an activated carbon test furnace with an anti-clogging function, belonging to the technical field of activated carbon preparation equipment. Background Art
[0002] Activated carbon is a specially treated carbon. Organic raw materials (fruit shells, coal, wood, etc.) are heated under air-tight conditions to reduce non-carbon components (this process is called carbonization), and then react with gas to erode the surface and produce a well-developed microporous structure (this process is called activation). The activated carbon activation method is divided into physical activation, chemical activation and physical-chemical composite activation. The physical activation method is generally carried out in two steps. First, the raw materials are carbonized at about 500°C, and then activated with superheated steam under high temperature. At high temperature, water vapor reacts with C atoms inside the carbon material to generate CO gas and escape, forming the porous structure of the carbon.
[0003] The activation device of China Patent Publication No. CN219314584U includes an activation cylinder and a rotating rod. A support frame is provided at the bottom of the activation cylinder, a feeding mechanism is provided on the left side of the top of the activation cylinder, and a motor for activated carbon is provided at the middle position of the top of the activation cylinder. A stirring blade is provided on the surface of the rotating rod, and two connecting rods are symmetrically provided at the middle position of the rotating rod. The other end of the connecting rod is detachably connected to a telescopic rod, and the other end of the telescopic rod is connected to a cleaning piece. By arranging stirring blades and cleaning pieces in the activation cylinder, the stirring blades are driven by the first motor to stir the activated carbon raw material, and the activation cylinder is heated by the steam heating generator. The high-temperature water vapor generated can fully contact with the activated carbon raw material, so that the reaction effect can be better and the quality of the produced activated carbon can be effectively improved. The cleaning piece is driven by the first motor to clean the inner wall of the activation cylinder to prevent the inner wall of the activation cylinder from adhering to the inner wall of the activation cylinder, and no manual cleaning is required.
[0004] However, the inventor of the above device believes that there are certain defects. The above device discharges the reacted material through a discharge pipe, and the material accumulates at the bottom of the activation cylinder. There is a lack of a mechanism for uniform discharge, which makes the discharge pipe prone to blockage. For this reason, the utility model provides an activated carbon test furnace with anti-blocking function. Utility Model Content
