Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0032] An activated carbon recovery and activation device according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0033] Reference Figure 1 and Figure 2 The present invention aims to provide an embodiment of an activated carbon recovery and activation device.

[0034] In this embodiment, the activation equipment mainly includes a first horizontal heating furnace, a second horizontal heating furnace, and a frame.

[0035] The frame is used to support and install the first horizontal heating furnace and the second horizontal heating furnace. Both can include a fixed seat and a movable seat, thereby facilitating the adjustment of the first horizontal heating furnace and the second horizontal heating furnace into position and reducing the difficulty of installation and commissioning.

[0036] For the first horizontal heating furnace, the first horizontal heating furnace includes a first furnace body 1 and a first screw propeller.

[0037] The first furnace body 1 forms a cavity for holding activated carbon, and the first screw propeller has a screw located inside the first furnace body 1. The screw is engaged with the inner wall of the first furnace body 1. When the screw rotates, the threads on the screw compress the activated carbon, causing the activated carbon to move toward the end of the first furnace body 1, and then causing the activated carbon to fall into the first discharge port 3 and be discharged.

[0038] In some specific embodiments of the present invention, the first furnace body 1 can be elongated, with a first feed inlet 2 at the top of one end of the first furnace body 1 and a first discharge outlet 3 at the bottom of the other end of the first furnace body 1. Meanwhile, the length direction of the screw is arranged along the length direction of the first furnace body 1, which can extend the movement path of the activated carbon and make the activated carbon fully heated.

[0039] The second horizontal heating furnace is similar to the first horizontal heating furnace, also including a second furnace body 4 and a second screw propeller. The second furnace body 4 is elongated, with a second feed port 5 at the top of one end of the second furnace body 4 and a second discharge port 6 at the bottom of the other end of the second furnace body 4. The second feed port 5 is located at the bottom of the first discharge port 3 to receive activated carbon from the first furnace body 1.

[0040] In some specific embodiments of the present invention, the heating structures of the first furnace body 1 and the second furnace body 4 can be different. For example, the first furnace body 1 is heated by a fluid medium to meet the need for lower temperature heating, while the second furnace body 4 directly uses heating tubes or heating wires to meet the need for higher temperature heating.

[0041] In order to facilitate the transfer of activated carbon from the first furnace body 1 to the second furnace body 4, this embodiment also includes a conveying pipe 7.

[0042] As the first furnace body 1 is heated, it will accumulate a lot of deformation along its length, making it difficult for the conveying pipe 7 to connect the first furnace body 1 and the second furnace body 4 at the same time, and it is prone to cracking.

[0043] To solve the above problems, this embodiment improves the conveying pipe 7. In some specific embodiments of the present invention, the conveying pipe 7 can include a first pipe body 8 and a second pipe body 9, the first pipe body 8 and the second pipe body 9 are connected and rotatably connected. The first pipe body 8 has a first connector 10 rotatably connected to the first discharge port 3, and the second pipe body 9 has a second connector 11 rotatably connected to the second inlet port 5.

[0044] In some specific embodiments of the present invention, for ease of understanding, in other words, the first tube 8 is horizontally rotatably connected to the first outlet 3, the first tube 8 is horizontally rotatably connected to the second tube 9, and the second tube 9 is horizontally rotatably connected to the second inlet 5.

[0045] As is easily understood, the present invention provides a conveying pipe 7, which includes a first pipe body 8 and a second pipe body 9 that are rotatably connected. The first pipe body 8 is rotatably connected to the first discharge port 3, and the second pipe body 9 is rotatably connected to the second feed port 5. Therefore, when the first furnace body 1 expands or contracts due to heating, the various parts of the conveying pipe 7 can rotate to adapt, avoiding leakage and ensuring reliable and effective conveying. At the same time, the various parts of the conveying pipe 7 can be made of high-temperature resistant metal, which is durable and not easily damaged, improving the reliability of conveying and facilitating the entry of activated carbon from the first furnace body 1 into the second furnace body 4.

[0046] In some specific embodiments of the present invention, a connecting sleeve 12 for realizing a rotatable connection may be provided between the first tube 8 and the second tube 9, and the connecting sleeve 12 is fitted onto the ends of the first tube 8 and the second tube 9.

[0047] As is readily apparent, this embodiment enables the first tube 8 and the second tube 9 to be connected via the connecting sleeve 12, thereby reducing the manufacturing difficulty of the first tube 8 and the second tube 9 and facilitating their manufacture by casting.

[0048] In some specific embodiments of the present invention, the first tube body 8 may have a first tapered tube portion 13 connected to the first connector 10, and the small end of the first tapered tube portion 13 is connected to the first connector 10.

[0049] It is readily apparent that this embodiment improves the shape of the first tube 8 to facilitate the entry of activated carbon into the second tube 9, and thus facilitates the entry of activated carbon into the second furnace body 4.

[0050] In some specific embodiments of the present invention, the center of the large end of the first tapered tube portion 13 may be offset from the center of the small end.

[0051] As is readily apparent, by having the centers of the two ends of the first tapered tube portion 13 deviate, the present invention also enables the first tube body 8 to have corresponding dimensions in the horizontal direction, which satisfies the need for rotation and expansion and is convenient to manufacture.

[0052] In some specific embodiments of the present invention, the inner diameter of the first tube 8 can be smaller than the inner diameter of the second tube 9.

[0053] It is readily apparent that this embodiment further facilitates the entry of activated carbon into the second furnace body 4 by making the inner diameter of the first tube 8 smaller than the inner diameter of the second tube 9, thereby preventing the pressure backflow of the second furnace body 4 from blocking the entry of activated carbon.

[0054] In some specific embodiments of the present invention, the second tube body 9 may have a second tapered tube portion 14 that connects to the second connector 11, with the large end of the second tapered tube portion 14 connected to the second connector 11.

[0055] It is easy to understand that by setting the second conical tube portion 14, this embodiment also makes the second tube body 9 have both horizontal dimensions and can gradually increase in the vertical direction, thereby facilitating manufacturing and meeting the needs of activated carbon passage.

[0056] In some specific embodiments of the present invention, the center of the large end of the second tapered tube 14 may be offset from the center of the small end.

[0057] As is readily apparent, this embodiment further increases the horizontal dimension range of the second tube body 9 by offsetting the center of the large end of the second conical tube section 14 with the center of the small end, which not only meets the expansion and contraction requirements of the first furnace body 1, but also facilitates manufacturing by casting, thereby reducing manufacturing costs.

[0058] In some specific embodiments of the present invention, the first discharge port 3 may have an inner tube 15 that can be extended up and down, and the inner tube 15 is connected to the first connector 10.

[0059] It is readily apparent that when the conveying pipe 7 needs to be disassembled and maintained, the inner insertion pipe 15 can be lifted upwards to provide space for disassembly and maintenance. At the same time, the inner insertion pipe 15 and the first discharge port 3 can be connected vertically, thereby satisfying the lifting and lowering requirements while preventing activated carbon leakage.

[0060] In some specific embodiments of the present invention, the inner tube 15 may be fitted with a spring 16, the top of the spring 16 abutting against the first furnace body 1, and the bottom of the spring 16 abutting against the pin on the outer surface of the inner tube 15.

[0061] As is easily understood, in this embodiment, by incorporating a spring 16, the inner insertion tube 15 can be automatically lowered with the assistance of the spring 16, thus preventing the inner insertion tube 15 from getting stuck and making it difficult for the delivery tube 7 to connect to the inner insertion tube 15.

[0062] In some specific embodiments of the present invention, an inner flange may be provided inside the first discharge port 3, and an outer flange may be provided on the outside of the inner tube 15. The outer flange is located at the bottom of the inner flange, and the outer flange and the inner flange cooperate to prevent detachment.

[0063] As is readily apparent, in this embodiment, the inner flange and the outer flange facilitate the installation of the inner tube 15, while preventing the inner tube 15 from falling off. Furthermore, the contact between the inner flange and the outer flange facilitates barrier sealing, allowing the activated carbon to smoothly enter the first tube 8.

[0064] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
