Description

Technical Field

[0001] The utility model relates to the technical field of activated carbon manufacturing furnaces, in particular to a cylinder sealing device used for activated carbon manufacturing furnaces. Background Art

[0002] Pyrolysis furnace and activation furnace are two key equipment in the manufacturing process of activated carbon.

[0003] Pyrolysis furnaces are mainly used in the pyrolysis process, which is to heat organic matter in the absence of oxygen or low oxygen conditions to break it down into smaller molecules. This process can produce solid, liquid and gas products, depending on the type of feedstock and pyrolysis conditions, and is the first step in energy and material production. There are also many types of pyrolysis furnaces, such as rotary pyrolysis furnaces, fixed bed pyrolysis furnaces, etc.

[0004] The activation furnace is mainly used to further process the solid carbon after carbonization to improve its pore structure and specific surface area, so that it has higher adsorption performance. The activation process usually uses water vapor or CO2 as an activator, which reacts chemically with the solid carbon at high temperature to produce activated carbon with high porosity. The activation furnace is used to improve the pore structure and specific surface area of ​​solid carbon, and is a key step in the production of high-performance activated carbon. There are also many types of activation furnaces, such as rotary activation furnaces, fluidized bed activation furnaces, etc.

[0005] However, the problem with rotary pyrolysis furnaces and activation furnaces at present is that the sealing of the dynamic and static joints of the furnace body is poor, which causes outside air to enter the furnace and trigger uncontrollable combustion, resulting in a sharp rise in furnace temperature, deformation of the furnace body, and unstable composition of pyrolysis products and properties of activated carbon, making it difficult to obtain solid (carbon), liquid (tar), gas (combustion gas), and activated carbon products with uniform properties.

[0006] In summary, how to effectively solve the problem of poor sealing at the static joint of the furnace body and cylinder of the activated carbon manufacturing furnace is an issue that technical personnel in this field urgently need to solve. Utility Model Content

The inner wall of the packing assembly and the outer wall of the compensation assembly are kept concentric, that is, the gap between the outer wall of the compensation assembly and the inner wall of the packing flange 5 is equal, and the gap is uniform everywhere, the inner wall of the packing flange 5 is not easy to contact the outer wall of the compensation assembly, and the packing flange 5 does not interfere with the rotation of the furnace body 1.

[0096] Among them, the receiving unit can be connected to the position sensor and the distance sensor to receive the current coordinate information of the central axis of the packing assembly detected by the position sensor and the coordinate information of the central axis of the compensation assembly detected by the distance sensor; the judging unit is connected to the receiving unit to judge whether the coordinate of the central axis of the packing assembly is equal to the coordinate of the central axis of the compensation assembly; the moving part is connected to the judging unit to control the central axis of the packing assembly to move to coincide with the central axis of the compensation assembly when the coordinate of the central axis of the packing assembly is not equal to the coordinate of the central axis of the compensation assembly.

[0097] In the above embodiment, the adjustment part can ensure that the inner wall of the packing assembly and the outer wall of the compensation assembly are concentric, that is, the gap between the outer wall of the compensation assembly and the inner wall of the packing flange 5 is equal, and the gap is uniform everywhere, the inner wall of the packing flange 5 is not easy to contact the outer wall of the compensation assembly, and the packing flange 5 does not interfere with the rotation of the furnace body 1.

[0098] More specifically, the moving part includes a calculation unit and a movement execution unit.

[0099] Among them, the calculation unit is connected to the judgment unit. When the judgment unit determines that the coordinates of the central axis of the packing assembly are not equal to the coordinates of the central axis of the compensation assembly, the calculation unit can calculate the distance between the current coordinates of the central axis of the packing assembly and the coordinates of the central axis of the compensation assembly, that is, the distance difference between the two. The distance difference is the optimal vector that the packing assembly should move.

[0100] After the calculation unit obtains the above-mentioned optimal vector, a movement signal is sent to the mobile execution unit to control the mobile execution unit to move the optimal vector, that is, to realize the optimal vector movement of the central axis of the packing assembly, to ensure that the inner wall of the packing assembly and the outer wall of the compensation assembly are concentric, the inner wall of the packing flange 5 is not easy to contact the outer wall of the compensation assembly, and the packing flange 5 does not interfere with the rotation of the furnace body 1.

[0101] Of course, according to the above-mentioned optimal vector, the mobile execution unit can also move within a reasonable range close to the optimal vector, that is, move within a circle with a set diameter centered on the optimal vector, thereby reducing the difficulty of moving the mobile execution unit and saving adjustment time.
