Description

Technical Field

[0001] This utility model relates to the field of rotary kiln technology, specifically to an activated carbon-activated rotary kiln. Background Technology

[0002] The activated carbon rotary kiln is a specialized piece of equipment used to convert carbon-containing raw materials (such as coal and wood) into activated carbon through high-temperature pyrolysis. It is a key piece of equipment in continuous heat treatment processes.

[0003] During operation, the rotary kiln is divided into three sections: preheating section, activation section, and cooling section. However, when the raw material is fed into the rotary kiln and enters the activation section, the contact area between the water vapor and the billet is low. A large amount of billet is difficult to fully contact with the water vapor, which will cause the billet to form holes and reduce its specific surface area.

[0004] In view of this, an activated carbon activation rotary kiln was designed to solve the above problems. Utility Model Content

[0005] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0006] Therefore, the technical solution adopted by this utility model is as follows: An activated carbon activation rotary kiln includes a brick kiln assembly and an evaporation assembly mounted on the brick kiln assembly. The brick kiln assembly includes a kiln body, with multiple baffles fixedly installed on the inner wall of the kiln body. A guide impeller is fixedly installed at one end of the kiln body, and a horizontally placed spray inner pipe is fixedly installed on the inner side of the guide impeller. Multiple pressure relief plugs are movably installed inside the spray inner pipe. The evaporation assembly includes a feeding chamber located outside the guide impeller. An internal evaporation pipe is fixedly installed in the middle of the feeding chamber. Multiple evenly distributed air holes are opened at the top of the internal evaporation pipe, and air jet plugs are movably installed inside the air holes.

[0007] In a preferred embodiment, the present invention can be further configured as follows: a ring gear is fixedly installed on the outside of the kiln body, a positioning ring is movably installed on the outside of the ring gear, two clamping plates are fixedly installed at the bottom of the positioning ring, a fixed base is movably installed on the outside of the clamping plates, and a U-shaped movable frame is installed on the outside of the two fixed bases.

[0008] In a preferred embodiment, the present invention can be further configured such that the U-shaped movable frame consists of two horizontal support plates and a rectangular support plate, and the two ends of the rectangular support plate are movably installed inside the two horizontal support plates.

[0009] In a preferred embodiment, the present invention can be further configured as follows: an annular gasket is movably installed on the outside of the kiln body, a clamp is fixedly installed on the inner side of the annular gasket, a stabilizing base is provided directly below the annular gasket, a lever is movably installed inside the clamp, a slide is movably installed at the other end of the lever, a bidirectional screw is movably installed inside the stabilizing base, and the slide is threaded onto the outside of the bidirectional screw. The inner end of the bidirectional lead screw is movably mounted inside the rectangular support plate.

[0010] In a preferred embodiment, the present invention can be further configured such that: a plurality of symmetrically distributed blades are fixedly installed on the inner side of the guide impeller.

[0011] In a preferred embodiment, the present invention can be further configured such that the top of the feeding chamber is funnel-shaped, and the bottom of the inner side of the feeding chamber is provided with a semi-circular groove that connects to the inner cavity of the kiln.

[0012] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows: 1. This utility model involves fixing a guide impeller at one end of the kiln body and movably installing a built-in evaporator tube horizontally positioned in the middle of the kiln body in the middle of the guide impeller. As the aqueous solution fills the built-in evaporator tube, the high temperature continuously released inside the kiln body will radiate onto the built-in evaporator tube. Finally, the aqueous solution will rapidly generate water vapor under the action of high temperature. The water vapor will be released towards the bottom of the kiln body cavity along the pressure relief gap at the bottom of the spray inner pipe. As the billet is flipped upward by the kiln body, the falling billet can fully contact the water vapor, thereby improving the pore formation and specific surface area of ​​the billet.

[0013] 2. This utility model movably installs the kiln body and ring gear inside the positioning ring. As the bidirectional screw is rotated, the slide will move laterally along the bidirectional screw. Finally, the slide will push the lever arm upward, and the kiln body and evaporation components will be effectively raised. Ultimately, this can increase the speed of billet transfer inside the kiln body and improve the discharge efficiency. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0017] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0018] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing an activated carbon activation rotary kiln.

[0019] Example 1: Combination Figures 1 to 5 As shown, the present invention provides an activated carbon activation rotary kiln, including a brick kiln assembly 100 and an evaporation assembly 200 installed on the brick kiln assembly 100. The brick kiln assembly 100 is used to activate and prepare billets, and the evaporation assembly 200 is used to increase the contact area between water vapor and billets, thereby increasing the activation efficiency of billets.

[0020] The brick kiln assembly 100 includes a kiln body 130, with multiple baffles 1303 fixedly installed on the inner wall of the kiln body 130, a guide impeller 160 fixedly installed at one end of the kiln body 130, a horizontally placed spray inner pipe 170 fixedly installed on the inner side of the guide impeller 160, and multiple pressure relief plugs 1701 movably installed inside the spray inner pipe 170. The evaporation assembly 200 includes a feeding chamber 210 disposed outside the guide impeller 160. An internal evaporation tube 220 is fixedly installed in the middle of the feeding chamber 210. The top of the internal evaporation tube 220 is provided with a plurality of evenly distributed air holes, and an air jet plug 230 is movably installed in the air holes. The top of the feeding chamber 210 has a funnel-shaped structure, and the bottom of the inner side of the feeding chamber 210 has a semi-circular groove that connects to the inner cavity of the kiln body 130.

[0021] Carbonaceous raw materials such as coal and wood chips are first burned until carbonized to form carbon blanks. Then, the carbon blanks are fed into the feeding chamber 210. Guided by the feeding chamber 210, the carbon blanks are effectively transferred to the bottom of the inner wall of the kiln body 130. As the kiln body 130 rotates and the carbon blanks are flipped by multiple ring pads 1301, the water vapor that has been evaporated at high temperature inside the built-in evaporation pipe 220 is squeezed out through the gap between the built-in evaporation pipe 220 and the jet plug 230. Finally, the water vapor enters the inner cavity of the spray inner pipe 170. The multiple pressure relief plugs 1701 evenly distributed at the bottom of the spray inner pipe 170 extend downward under the action of gravity. Finally, the water vapor in the inner cavity of the spray inner pipe 170 is released along the bottom of the inner cavity of the kiln body 130 and fully contacts the flipped carbon blanks, thereby improving the efficient activation of the carbon blanks and water vapor.

[0022] Example 2: Combination Figure 3 As shown, based on Example 1, a ring gear 120 is fixedly installed on the outside of the kiln body 130, a positioning ring 1102 is movably installed on the outside of the ring gear 120, two clamping plates 1101 are fixedly installed at the bottom of the positioning ring 1102, a fixed base 110 is movably installed on the outside of the clamping plates 1101, and a U-shaped movable frame 1103 is installed on the outside of the two fixed bases 110. The U-shaped movable frame 1103 consists of two horizontal support plates and a rectangular support plate, with the two ends of the rectangular support plate movably installed inside the two horizontal support plates.

[0023] Preferably, the bottom of the positioning ring 1102 is provided with a fan-shaped slot, and the fan-shaped slot is used to provide an auxiliary rotation path for the external drive device; The two fixed bases 110 and the stabilizing base 140 are all provided with elliptical holes. Bolts are inserted into the elliptical holes to fix the two fixed bases 110 and the stabilizing base 140 to the concrete platform. The stabilizing base 140 is used to provide a leveling support for the horizontally placed kiln body 130.

[0024] Example 3: Combination Figure 3 As shown, in the above embodiment, an annular gasket 1301 is movably installed on the outside of the kiln body 130, a clamping seat 1302 is fixedly installed on the inside of the annular gasket 1301, a stabilizing base 140 is provided directly below the annular gasket 1301, a lever arm 1502 is movably installed inside the clamping seat 1302, a slide block 1501 is movably installed at the other end of the lever arm 1502, a bidirectional screw rod 150 is movably installed inside the stabilizing base 140, and the slide block 1501 is threaded onto the outside of the bidirectional screw rod 150. The inner end of the double-acting lead screw 150 is movably installed inside the rectangular support plate; Multiple blades are symmetrically distributed and fixedly installed on the inner side of the feed impeller 160.

[0025] When the external drive device drives the ring gear 120 and the kiln body 130, the guide impeller 160 installed at the outer end of the kiln body 130 will also rotate. As the guide impeller 160 rotates clockwise, its inner blades will actively deliver the falling carbon billets in the feeding chamber 210, ensuring that the amount of carbon billets transferred in the feeding chamber 210 is constant and avoiding the problem of billet accumulation. Furthermore, by rotating the bidirectional lead screw 150, the slide 1501 will move closer to the stabilizing base 140 along the threaded section of the bidirectional lead screw 150, while the lever arm 1502 will push the clamp 1302 upward. At this time, the positioning ring 1102 and the two clamps 1101 will tilt along the two fixed bases 110 as the axis. After one end of the kiln body 130 and the evaporation assembly 200 are lifted, the fed carbon billet can be quickly discharged after being activated.

[0026] The working principle and usage process of this utility model: According to the requirements of activated carbon activating paper cups, the wheel at the outer end of the bidirectional lead screw 150 is rotated in advance. As the bidirectional lead screw 150 rotates clockwise, the slide 1501 will move laterally towards the stabilizing base 140 along the threaded section of the bidirectional lead screw 150. The lever arm 1502, which is movably installed on the slide 1501, will push the clamp 1302 and the ring pad 1301 to flip upwards. The end of the kiln body 130 near the evaporation component 200 will tilt upwards. Next, the raw materials are transferred to the inner cavity of the kiln body 130 using the feeding hopper 210. Accompanied by the external drive device driving the ring gear 120, the ring gear 120 and the kiln body 130 rotate uniformly around the positioning ring 1102 as the axis. The raw materials are transferred from one inclined and raised end of the kiln body 130 to the other. As the raw materials undergo high-temperature activation treatment inside the kiln body 130, the bidirectional lead screw 150, which rotates synchronously with the kiln body 130, and its internally distributed sliding blocks 1501 will open and close regularly. The water inside the closed, high-temperature evaporation tube 220 is continuously evaporated. The evaporated steam pushes the jet plug 230 upward, and eventually the steam enters the inner cavity of the bidirectional screw 150. The steam in the inner cavity of the bidirectional screw 150 is output downward from the openings of the multiple slide seats 1501 at the bottom. At this time, the steam will transfer upward along the bottom of the inner cavity of the kiln body 130, thereby increasing the contact area with the raw materials, enhancing the activation speed of the raw materials, and improving the utilization rate of thermal energy.
