Description

Technical Field

[0001] This utility model relates to the field of carbonization equipment technology, specifically an activated carbon carbonization furnace. Background Technology

[0002] Activated carbon is a specially treated type of carbon. Organic raw materials (such as fruit shells, coal, and wood) are heated in the absence of air to reduce non-carbon components. Therefore, carbonization is an essential step in the production process and requires the use of a carbonization furnace to carbonize the activated carbon. Existing carbonization furnaces have an internal cavity in which the raw materials for producing activated carbon are placed, and a heating source is used at the bottom for heating.

[0003] In existing carbonization furnaces, the activated carbon raw material is placed directly in the inner cavity, and heat is provided by a heating source below. During heating, the bottom of the inner cavity is heated first, and the heat spreads upward with the flame, gradually heating the rest of the inner cavity. This easily leads to the temperature in the bottom area of ​​the inner cavity being higher than that in the upper area, resulting in uneven carbonization of the activated carbon inside the inner cavity. Furthermore, the soot produced by incomplete combustion adheres to the outer wall of the inner cavity. When a large amount of soot accumulates, it affects heating efficiency and makes it difficult to clean the soot. Utility Model Content

[0004] The purpose of this invention is to provide an activated carbon carbonization furnace to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An activated carbon carbonization furnace includes a furnace body and a heating source disposed at the bottom of the furnace body, and further includes:

[0007] A rotating assembly is disposed inside the furnace body. The rotating assembly includes two symmetrically fixed support rings installed inside the furnace body. A rotating cylinder is movably disposed between the two support rings. A scraper is fixedly installed inside the furnace body, and the scraper is movably fitted with the rotating cylinder.

[0008] The feeding assembly is located inside the rotating drum. The feeding assembly includes a top cover that passes through the rotating drum and is fixedly connected to the furnace body. A bottom hopper is movably provided inside the rotating drum below the top cover.

[0009] Furthermore, multiple support bars are fixedly installed at equal angles inside the rotating drum, and the two ends of the support bars are fixedly connected to the furnace body. Multiple sliding grooves are opened at equal angles on the outer surface of the bottom chamber, and the multiple support bars slide into the sliding grooves at corresponding positions.

[0010] Furthermore, L-shaped rails are symmetrically fixedly installed on both sides of the inner surface of the top cover, and arc-shaped clips are symmetrically fixedly installed on both sides of the inner surface of the bottom compartment, with the arc-shaped clips slidingly inserted into the L-shaped rails.

[0011] Furthermore, a No. 1 end plate is fixedly installed at one end of the top cover, and the No. 1 end plate is movably fitted with the inner surface of the bottom compartment, while a No. 2 end plate is fixedly installed at one end of the inner surface of the bottom compartment.

[0012] Furthermore, multiple ball bearings are movably embedded in the inner surface of the support ring at equal angles, and all the ball bearings are in movable contact with the rotating drum.

[0013] Furthermore, a gear ring is fixedly installed at one end of the outer surface of the rotating drum, and a gear is rotatably connected to one end of the furnace body via a bearing, the gear meshing with the gear ring for transmission.

[0014] Preferably, a motor capable of driving the gear is fixedly installed on one end surface of the furnace body, and a retaining ring is fixedly installed on the outer surface of the rotating drum on one side of the gear ring.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The motor drives the drum to rotate, causing the heated bottom to rotate upwards. As the drum is heated evenly, the heat is evenly transferred to the top cover and bottom chamber inside. By rotating and heating the drum, the bottom chamber is prevented from overheating, and the activated carbon is heated evenly to maintain a uniform degree of carbonization.

[0017] 2. The bottom silo is supported by multiple support bars. With the sliding connection between the support bars and the chute, the bottom silo can be moved out and into the furnace body, which facilitates the loading and unloading of activated carbon.

[0018] 3. When the drum rotates, the scraper scrapes across the outer wall of the drum, removing the soot on the surface so that it can be discharged with the flue gas, thus preventing excessive accumulation of soot from affecting the heating efficiency. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-6 In this embodiment of the present invention, an activated carbon carbonization furnace includes a furnace body 1 and a heating source 101 disposed at the bottom of the furnace body 1. It also includes a rotating assembly 2 disposed inside the furnace body 1. The rotating assembly 2 includes two support rings 201 symmetrically and fixedly installed inside the furnace body 1. A rotating cylinder 203 is movably disposed between the two support rings 201. A scraper 102 is fixedly installed inside the furnace body 1, and the scraper 102 is movably fitted with the rotating cylinder 203. A feeding assembly 3 is disposed inside the rotating cylinder 203. The feeding assembly 3 includes a top cover 301 that passes through the rotating cylinder 203 and is fixedly connected to the furnace body 1. A bottom chamber 303 is movably disposed inside the rotating cylinder 203 below the top cover 301.

[0028] Specifically, the heating source 101 is the existing carbonization furnace heating method. The bottom of the furnace body 1 is heated. The activated carbon raw material is placed in the inner cavity formed by the top cover 301 and the bottom chamber 303. The heat is evenly transferred to the inner cavity through the rotating component 2 to carbonize the activated carbon. When the rotating drum 203 rotates, the scraper 102 scrapes across the outer wall of the rotating drum 203 to scrape off the soot on the surface and discharge it with the flue gas to prevent the soot from accumulating too much and affecting the heating efficiency.

[0029] Example 1

[0030] like Figure 1 , Figure 2 and Figure 6As shown, in this embodiment, multiple ball bearings 202 are movably embedded in the inner surface of the support ring 201 at equal angles, and all the ball bearings 202 are in contact with the rotating drum 203. The ball bearings 202 rotate on the inner surface of the support ring 201 to support the rotating drum 203 and reduce the friction when the rotating drum 203 rotates. A gear ring 205 is fixedly installed at one end of the outer surface of the rotating drum 203. A gear 206 is rotatably connected to one end of the furnace body 1 through a bearing. The gear 206 meshes with the gear ring 205 for transmission. A motor 207 that can drive the gear 206 to rotate is fixedly installed on one end of the furnace body 1. A retaining ring 204 is fixedly installed on the outer surface of the rotating drum 203 on one side of the gear ring 205. The retaining ring 204 blocks the spread of flame and smoke from one end of the outer surface of the rotating drum 203, reducing the impact of flame and smoke on the gear ring 205.

[0031] In this embodiment, the motor 207 operates, driving the gear 206 to rotate. Through the meshing transmission between the gear 206 and the gear ring 205, the rotating drum 203 rotates, causing the bottom heated position to rotate upwards. When the rotating drum 203 is heated evenly, the heat is evenly transferred to the top cover 301 and the bottom chamber 303 on its inner side. Thus, by rotating and heating the rotating drum 203, overheating of the bottom chamber 303 is avoided, and the activated carbon is heated evenly, maintaining the uniformity of activated carbon carbonization.

[0032] like Figure 2 , Figure 5 and Figure 6 As shown, in this embodiment, multiple support bars 306 are fixedly installed at equal angles inside the rotating drum 203. The two ends of the support bars 306 are fixedly connected to the furnace body 1. Multiple sliding grooves 304 are opened at equal angles on the outer surface of the bottom chamber 303. The multiple support bars 306 are slidably inserted into the sliding grooves 304 at the corresponding positions. A first end plate 302 is fixedly installed at one end of the top cover 301. The first end plate 302 is movably fitted with the inner surface of the bottom chamber 303. A second end plate 305 is fixedly installed at one end of the inner surface of the bottom chamber 303. The second end plate 305 blocks one end of the bottom chamber 303 to prevent activated carbon from falling from the end of the bottom chamber 303 when the bottom chamber 303 is moved out.

[0033] In practice, the bottom chamber 303 is supported by multiple support bars 306. With the sliding connection between the support bars 306 and the chute 304, the bottom chamber 303 can move out and into the furnace body 1, which facilitates the loading and unloading of activated carbon. The lower end of the first end plate 302, together with multiple support bars 306, clamps the end of the bottom chamber 303, limiting the maximum depth of the bottom chamber 303.

[0034] Example 2

[0035] Based on Embodiment 1, in order to compensate for the poor sealing at the connection between the bottom compartment 303 and the top cover 301.

[0036] like Figure 3 and Figure 4 As shown, in this embodiment, L-shaped rails 307 are symmetrically fixedly installed on both sides of the inner surface of the top cover 301, and arc-shaped strips 308 are symmetrically fixedly installed on both sides of the inner surface of the bottom compartment 303. The arc-shaped strips 308 and the L-shaped rails 307 are slidably inserted into each other.

[0037] In practice, when the bottom compartment 303 slides, the arc-shaped locking strip 308 slides inside the L-shaped locking rail 307. When the bottom compartment 303 is in place, the sliding fit between the arc-shaped locking strip 308 and the L-shaped locking rail 307 increases the sealing and connection strength at the connection between the bottom compartment 303 and the top cover 301.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0039] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
