Technical Field

[0001] The utility model relates to the technical field of activated carbon production equipment, in particular to a calcining mechanism for producing wood activated carbon. Background Art

[0002] Wood activated carbon is made of high-quality firewood, sawdust, peach pits, coconut shells, etc. It is produced in accordance with the national standards for wood activated carbon using the most popular processes today, such as phosphoric acid method and zinc chloride method. These processes make the mesoporous structure and specific surface area of ​​wood activated carbon more developed, resulting in large adsorption capacity and fast filtration speed. It has high strength, low ash content, reasonable pore size distribution, and high ignition point.

[0003] At present, the calcining device for producing wood activated carbon includes a calcining mechanism, a storage container and a calcining container. The calcining mechanism calcines and heats the storage container in the calcining container, thereby heating the activated carbon raw materials in the storage container at a high temperature under the condition of air isolation. However, the above calcination method will cause the activated carbon raw materials to pile up together, so that the contact with the storage container is not sufficient, and the calcination effect of the carbon-containing raw materials is not ideal. Utility Model Content

[0004] The utility model aims to provide a calcining mechanism for producing wood activated carbon, which can solve the problem that the traditional calcining method has an unsatisfactory calcining effect on carbon-containing raw materials.

Two rows of mesh disks are movably installed in the calcining box. The mesh disk is a bearing frame with a metal mesh cover at the bottom. The activated carbon raw material is placed in the mesh disk, which is vertically installed in the calcining box, with the ignition device and the spray device facing the two sides.

[0007] Preferably, a cover plate is movably mounted on the mesh disk, and the cover plate is composed of a frame body and a metal mesh cover; an opening for mounting the cover plate is provided on one side of the supporting frame, and a handrail is provided on the other side.

[0008] Preferably, a grid for containing activated carbon raw materials is provided in the mesh tray.

[0009] Preferably, a handle is provided on one side of the cover plate.

[0010] Preferably, the ignition device comprises an air pipe, on which a plurality of dome tubes are arranged at equal intervals, and the dome tubes extend into the calcining box. A flame spray head is arranged on the dome tubes.

[0013] Preferably, an inlet for installing the mesh disk is provided on one side of the calcining box. Two fixing plates are horizontally provided in the calcining box, and the fixing plates are butted against the bottom of the inlet.

[0024] Embodiment 1

[0025] The utility model greatly increases the heating area and water mist contact area of ​​the activated carbon raw materials by placing the activated carbon raw materials in a mesh plate and vertically installing the plate in a calcining box, thereby improving the calcining effect of the activated carbon raw materials and avoiding the problem of unsatisfactory calcining effect caused by overly concentrated accumulation of the activated carbon raw materials.

[0026] like Figure 1-2 As shown, a calcining mechanism for producing wood activated carbon includes a calcining box 1 and an ignition device 2 and a spray device 3 arranged alternately on both sides of the calcining box 1. Two rows of mesh plates 4 are movably installed in the calcining box 1.

[0027] like Figure 4-5 As shown, the mesh tray 4 is a supporting frame 42 with a metal mesh cover at the bottom. The mesh tray 4 contains the activated carbon raw material and is vertically installed in the calcining box 1, with the ignition device 2 and the spray device 3 facing both sides.

[0028] Furthermore, a cover plate 41 is movably mounted on the net disk 4, and the cover plate 41 is composed of a frame body 411 and a metal mesh cover. An opening 421 for mounting the cover plate 41 is provided on one side of the carrying frame 42, and a handrail 422 is provided on the other side.

[0029] Furthermore, a grid 43 for holding the activated carbon raw material is provided in the mesh tray 4. The function of the grid is to evenly hold the activated carbon raw material, and when the mesh tray 4 is installed in the calcining box 1 in a vertical state, it can prevent the activated carbon raw material from falling to the bottom of the mesh tray 4 due to gravity, ensuring that the average density and thickness of the activated carbon raw material on the mesh tray are the same.

[0030] Furthermore, a handle 412 is provided on one side of the cover plate 41 .

[0031] like Figure 3As shown, further, the ignition device 2 comprises a gas pipe 21, on which a plurality of dome pipes 22 are arranged at equal intervals, and the dome pipes 22 extend into the calcining box 1. A flame head 221 is arranged on the dome pipe 22. External fuel gas is introduced into the gas pipe 21.

[0032] Further, the spray device 3 comprises a water pipe 31, on which a plurality of branch pipes 32 are arranged at equal intervals, and the branch pipes 32 extend into the calcining box 1. A spray nozzle 321 is arranged on the branch pipe 32. The water pipe 31 is connected to an external water pump.

[0033] Furthermore, at least two groups of ignition devices 2 and spray devices 3 are provided on both sides of the calcining box 1 .

[0034] Furthermore, an inlet 11 for installing the mesh plate 4 is provided on one side of the calcining box 1. Two end fixing plates 12 are horizontally provided in the calcining box 1, and the fixing plates 12 are butted against the bottom of the inlet 11.

[0035] Working principle:

[0036] The mesh tray 4 is placed flat on the floor, and the cover plate 41 is pulled out from the opening 421 by holding the handle 412. Then the activated carbon raw material is poured onto the mesh tray 4 and smoothed so that the activated carbon is evenly distributed in each grid of the grille 43. Then the cover plate 41 is inserted into the mesh tray 4 from the opening 421 to fix the activated carbon raw material in the mesh tray 4.

[0037] After the above steps are completed, the mesh plate 4 is vertically installed into the calcining box 1 from the inlet 11. The flame head 221 ignites and sprays flames to heat the activated carbon raw material in the mesh plate 4. After heating for a period of time, the spray device 3 is started, and the spray nozzle 321 sprays water mist, which acts as an activator to achieve the effect of pore creation and opening, thereby causing the activated carbon raw material to produce more holes.

[0038] After the calcination process is completed, the mesh plate 4 is pulled out of the calcination box 1 through the handrail 422. The cover plate 41 is pulled out from the opening 421 by holding the handle 412, and then the activated carbon raw material is poured out from the mesh plate 4 to form the completed activated carbon.
