The new activation furnace 100 for activated carbon production comprises an activation cylinder 110, which can be in a closed structure after being closed, and the outer periphery of the activation cylinder 110 can be provided with heat preservation materials. An annular support table 111 is arranged in the bottom inner cavity of the activation cylinder 110, which is used to limit the movement of the support table 120. The support table 120 is arranged above the annular support table 111 and can be lifted or dropped under the lifting of the lifting assembly 150. The support table 120 has an inner cavity, and the top of the support table 120 is inwardly retracted to form a mounting plane 121. The top of the mounting plane 121 is vertically communicated with a plurality of aeration pipes 130. Aeration holes 131 are arranged on the outer periphery of the aeration pipes 130. After high-temperature steam is introduced into the inner cavity of the support table 120 through external equipment, the high-temperature steam can flow out of the aeration holes 131 of the aeration pipes 130 into the activation cylinder 110, so as to react with the materials in the activation cylinder 110. A plurality of aeration seats 140 are communicated with the outer side wall of the support table 120 and are arranged in an annular array along the outer periphery of the support table 120. The aeration seats 140 are similar to the aeration pipes 130, and both are provided with aeration holes 131. The high-temperature steam in the inner cavity of the support table 120 can be released from the aeration seats 140 and slowly rise upward in the activation cylinder 110 to react with each material in the activation cylinder 110. The top of the mounting plane is fixedly provided with a mounting boss 132. The mounting boss 132 is connected with a vertically arranged rotating rod 133 through a driving assembly. The outer periphery of the rotating rod 133 is provided with a spiral raking plate 134. After the activation reaction is completed, the lifting assembly 150 drives the support table 120 and the aeration pipes 130 to drop together. The bottom of the support table 120 is supported at the annular support table 111. The discharge port 113 leaks out. The activated carbon in the activation cylinder 110 slides along the outer inclined surface of the support table 120 to the discharge port 113 and is discharged. The driving assembly drives the rotating rod 133 and the raking plate 134 to rotate, which can continuously move the activated carbon on the top of the mounting boss 132 outward, so that the activated carbon above it can be completely discharged to the outside of the activation cylinder 110. The top of the activation cylinder 110 is provided with a discharging port 112. The materials are added into the activation cylinder 110 through the discharging port 112. The bottom of the support table 120 and the bottom wall of the activation cylinder 110 are jointly provided with the lifting assembly 150. The lifting assembly 150 can be a screw structure with a telescopic structure, a hydraulic cylinder structure or any other form, as long as it meets the use requirements. The outer side wall of the activation cylinder 110 is provided with at least one discharge port 113 above the annular support table 111. The discharge port 113 is connected with an inclined unloading pipe 114. The activated carbon after the activation is discharged to the unloading pipe 114 through the discharge port 113 and is drained to the packaging workshop through the unloading pipe 114.
[0020] In the embodiment of the present application, the working process is that the specially treated carbon, the organic raw material shell, the coal box and the wood and other materials are put into the activation cylinder 110 through the discharge port 112, the materials are blocked and supported by the support table 120, then the external high-temperature gas is introduced into the inner cavity of the support table 120, the high-temperature gas flows out through the aeration seat 140 and the aeration pipe 130 respectively, the high-temperature steam in the aeration pipe 130 can be uniformly released in each area of the activation cylinder 110, the high-temperature gas flow at the aeration seat 140 flows upward after being released and reacts with the materials above, when the reaction is completed, the lifting assembly 150 drives the support table 120 to fall as a whole, at this time the discharge port 112 leaks out from one side of the support table 120, after the valve at the discharge port 112 is opened, the activated carbon in the activation cylinder 110 can be discharged to the discharge pipe 114 along the discharge port 112.
[0021] As can be seen from the above, in the embodiment of the present application, the aeration seat 140 and the aeration pipe 130 are arranged to introduce high-temperature steam into the activation cylinder 110, and then the high-temperature steam is introduced into the activation cylinder 110 from the bottom and each part inside the activation cylinder 110, so that the activated carbon in the activation furnace can be more uniformly contacted with the high-temperature steam, and the yield of the product is further ensured. In the embodiment of the present application, the support table 120 is arranged, and the top of the support table 120 is inwardly contracted to form the mounting plane 121, and then the outer wall of the support table 120 has a certain slope, and further, when the lifting assembly 150 drives the support table 120 to fall as a whole, the materials in the activation cylinder 110 can slide down and be discharged to the discharge port 113 through the outer wall of the support table 120, and the rotation rod 133 and the raking plate 134 are arranged to cooperate to raking the activated carbon above the support table 120 to slide outward to facilitate the discharge.
[0022] In some embodiments, the inner cavity of the support table 120 is provided with an annular closed ring 115, the top end and the bottom end of the closed ring 115 are sealingly connected to the top wall and the bottom wall of the inner cavity respectively, so that the closed ring 115 divides the inner cavity of the support table 120 into a first chamber 116 inside the inner circle of the closed ring 115 and a second chamber 117 outside the outer circle. In the embodiment of the present application, the inner cavity of the support table 120 is divided into the first chamber 116 and the second chamber 117 by the above arrangement, and then high-temperature steam with different temperatures or gas pressures can be introduced into the two chambers respectively, so that the introduction of high-temperature steam into the activation cylinder 110 can be more finely controlled to meet the differentiated and precise production requirements.
[0023] In some embodiments, the discharge port 112 is located at the top center axis of the activation cylinder 110. In the embodiment of the present application, through the above arrangement, the materials can be more uniformly distributed in the activation cylinder 110 during the feeding process.
[0024] In some embodiments, the top ends of the plurality of aeration pipes 130 are connected together with a conical protective cover 160, and the top end of the protective cover 160 is a smooth arc-shaped end face. In the embodiments of the present application, the plurality of aeration pipes 130 are connected as a whole by the protective cover 160, thereby improving the compression resistance and increasing the strength. After the material at the top discharge port 112 is fed into the activation cylinder 110, the material will be distributed to the periphery through the protective cover 160, thereby further improving the uniformity of the material after entering the activation cylinder 110.
[0025] In some embodiments, the bottom of the support table 120 is vertically provided with a plurality of limiting rod members 122, and the inner side wall of the activation cylinder 110 is connected with a plurality of limiting rings 118 below the support table 120, and the limiting rod members 122 penetrate through the limiting rings 118. In the embodiments of the present application, when the support table 120 is lifted or falls during the lifting process of the lifting assembly 150, the limiting rod members 122 will slide under the arrangement of the limiting rings 118, thereby further ensuring the stability of the support table 120 during the reciprocating movement.
[0026] In some embodiments, the discharge port 113 is four, and the four discharge ports 113 are uniformly distributed in a ring array on the outer periphery of the activation cylinder 110. In the embodiments of the present application, by arranging four discharge ports 113, the unloading rate is further improved.
