Description

Technical Field

[0001] The utility model relates to the technical field of activated carbon preparation equipment, in particular to a carbonization device for preparing activated carbon. Background Art

[0002] Activated carbon activation is one of the most important steps in the production of activated carbon. Activated carbon activation is generally divided into four main processes according to the temperature change of the thermal decomposition process:

[0003] First: Drying process

[0004] The main process is to evaporate the moisture contained in the raw materials by relying on external heat. The temperature is controlled at around 150 degrees. The temperature is not high so the chemical composition of the wood material does not change.

[0005] Second: Pre-carbonization process

[0006] As the temperature rises to around 275 degrees, the thermal decomposition reaction of the wood material becomes obvious, and the chemical composition of the raw materials begins to change. Unstable components such as hemicellulose decompose to produce carbon dioxide, carbon monoxide and a small amount of acetic acid.

[0007] Third: Carbonization process

[0008] It is the most important step in the carbonization of activated carbon. The temperature reaches about 400 degrees, so it is also called the exothermic reaction stage. The raw materials undergo rapid thermal decomposition to generate a large number of decomposition products. The generated liquid products contain a large amount of acetic acid, methanol and wood tar. The carbon dioxide content in the generated gas products gradually decreases, while the combustible gases such as methane and ethylene gradually increase.

[0009] Fourth: Calcination process

[0010] The temperature of this process reaches 500 degrees and the charcoal is calcined by external heat supply. At this time, very little liquid product is generated, and the volatile substances remaining in the charcoal are discharged, thereby increasing the fixed carbon content of the charcoal.

[0011] In the prior art, when preparing activated carbon, the activated carbon raw materials are often piled in a carbonization device (carbonization furnace). The raw materials are not heated evenly, which will lead to uneven carbonization and poor carbonization effect. In addition, since the raw materials need to be heated in a closed container and the carbonization temperature is relatively high, it is not easy to disturb the raw materials in the carbonization device to make them evenly distributed. Therefore, a carbonization device for preparing activated carbon is needed. Utility Model Content

[0016] Preferably, support columns are arranged on the left and right sides of the carbonization housing, and connecting shafts rotatably connected to the support columns are fixed to the outer walls on the left and right sides of the carbonization housing;

[0017] The drive assembly drives one of the connecting shafts to rotate.

[0018] Preferably, the driving assembly includes a motor and a transmission member, the motor is fixed to one side of one of the support columns, and the output shaft of the motor drives the connecting shaft to rotate through the transmission member.

[0019] Preferably, the transmission member comprises a transmission gear, or a transmission wheel and a transmission belt, or a transmission sprocket and a transmission chain;

[0020] The contact portion between the connecting shaft and the outer wall of the carbonized casing is fixedly connected via a heat insulating block.

[0021] Preferably, a vacuum pump is fixed at the front end of the carbonizing casing, and the air in the carbonizing casing is extracted when the vacuum pump is started.

[0022] Preferably, a sleeve column is sleeved on the outer side of each of the plurality of partition columns, and the sleeve column is coaxially arranged with the partition column and rotatably connected with the partition column.

[0023] Preferably, the outer sides of the plurality of partition columns are rotatably connected with sleeve columns, and the sleeve columns are provided with a plurality of circumferentially protruding flanges, and the cross-section of the flanges is elliptical.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] Example 1

[0035] refer to Figure 1-2A carbonization device for preparing activated carbon shown in the figure comprises a carbonization casing 1 with a heater 2 fixed at the lower end, a feeding port is arranged at the upper end of the carbonization casing 1, a discharging port is arranged at the rear end of the carbonization casing 1, a feeding cover 9 and a discharging cover 10 are arranged at the feeding port and the discharging port respectively, the feeding cover 9 and the discharging cover 10 adopt the cover body which is commonly used in the prior art and is suitable for the present embodiment and is electrically driven, and can be automatically opened and closed according to the instructions of the computer (or controller), so as to ensure the safety of the staff and to be able to discharge the carbonized raw materials in time;

[0036] A vertically arranged partition column 7 is fixed to the inner bottom wall of the carbonization housing 1. A plurality of partition columns 7 are arranged and evenly and staggeredly distributed in the carbonization housing 1.

[0037] A driving assembly for driving the carbonization housing 1 to rotate is arranged on one side of the carbonization housing 1 .

[0038] Based on the above structure, when the raw materials for preparing activated carbon are placed in the carbonizing casing 1, the raw materials are dispersed under the action of multiple partition columns 7, so that the raw materials are evenly distributed in the carbonizing casing 1, which is conducive to making the raw materials evenly distributed in the carbonizing casing 1, and providing a good distribution space for subsequent uniform heating. The partition columns 7 can conduct heat, and conduct the heat generated by the heater 2 at the lower part of the carbonizing casing 1 to various positions in the carbonizing casing 1, thereby achieving uniform heating of the raw materials in various parts of the carbonizing casing 1, enhancing the uniformity of the carbonization treatment, improving the carbonization efficiency, and at the same time improving the qualified rate of the carbonized products.

[0039] Furthermore, support columns 3 are provided on the left and right sides of the carbonization housing 1, and connecting shafts 4 rotatably connected to the support columns 3 are fixed to the outer walls on the left and right sides of the carbonization housing 1;

[0040] The driving assembly includes a motor 6 and a transmission member. The motor 6 is fixed to one side of one of the support columns 3. The output shaft of the motor 6 drives the connecting shaft 4 to rotate through the transmission member.

[0041] By setting the driving assembly and the connecting shaft 4, the carbonizing casing 1 can be driven to move circumferentially along the connecting shaft 4 while carbonizing the raw materials therein, so that the raw materials in the carbonizing casing 1 are disturbed, distributed more evenly, and the carbonization effect is better.

[0042] The transmission parts include but are not limited to transmission gears, transmission wheels and transmission belts, transmission sprockets and transmission chains, and other transmission elements commonly used in the prior art and suitable for use in this embodiment to achieve the transmission purpose, or a combination thereof;

[0043] The contact portion between the connecting shaft 4 and the outer wall of the carbonization casing 1 is fixedly connected via a heat insulating block, thereby isolating the heat of the carbonization casing 1 and preventing the heat from being lost through the connecting shaft 4 and causing energy waste.

[0044] Furthermore, a vacuum pump 5 is fixed at the front end of the carbonization casing 1. When the vacuum pump 5 is started, the air in the carbonization casing 1 is extracted. Through the setting of the vacuum pump 5, the air in the carbonization casing 1 can be extracted before carbonization, fully satisfying the oxygen-deficient environment and ensuring the effectiveness of carbonization.

[0045] Example 2

[0046] refer to Figure 3 The carbonization device for preparing activated carbon shown in the figure is different from that in Example 1 in that a plurality of partition columns 7 are sleeved with a sleeve column 8 on the outside, and the sleeve column 8 is coaxially arranged with the partition column 7 and rotatably connected with the partition column 7 .

[0047] By setting the sleeve column 8, the friction between the raw material and the partition column 7, as well as the friction between the raw material and the sleeve column 8 itself can be reduced when the raw material is turned over, thereby reducing the loss of the raw material and, at the same time, extending the service life of the partition column 7 and the sleeve column 8 to a certain extent.

[0048] Example 3

[0049] refer to Figure 4 The carbonization device for preparing activated carbon shown in the figure is different from Example 1 or Example 2 in that: a plurality of partition columns 7 are rotatably connected to the outer sides with a sleeve column 8, and a plurality of circumferentially protruding flanges 81 are provided on the sleeve column 8. The cross-section of the flange 81 is elliptical. Through the setting of the flange 81, the raw materials can be better separated in the horizontal direction, so that the raw materials are more evenly distributed in the carbonization casing 1.

[0050] Working principle of the utility model: in daily use, first add raw materials into the carbonizing casing 1 through the feeding port at the upper end of the carbonizing casing 1, then close the feeding cover 9 to form a closed space in the carbonizing casing 1, and then use the vacuum pump 5 to extract the air in the carbonizing casing 1 to fully meet the oxygen-deficient environment and ensure the effectiveness of carbonization; further turn on the heater 2 so that the heater 2 gradually heats up to carbonize the raw materials in the carbonizing casing 1. During the carbonization process, start the motor 6 so that the motor 6 drives the connecting shaft 4 to rotate through the transmission member, so that the carbonizing casing 1 moves circumferentially along the connecting shaft 4, so that the raw materials in the carbonizing casing 1 are disturbed, the distribution is more even, and the carbonization effect is better. After the carbonization is completed, the carbonizing casing 1 is stopped. The discharge port is kept in a downward vertical state, and the discharge cover 10 is opened to discharge the carbonized raw material from the discharge port, thereby completing the carbonization treatment of the raw material. In this process, when the activated carbon preparation raw material is placed in the carbonization casing 1, the raw material is dispersed under the action of multiple partition columns 7, so that the raw material is evenly distributed in the carbonization casing 1, which is conducive to making the raw material evenly distributed in the carbonization casing 1, providing a good distribution space for subsequent uniform heating, and the partition columns 7 can conduct heat, and conduct the heat generated by the heater 2 at the lower part of the carbonization casing 1 to various positions in the carbonization casing 1, thereby achieving uniform heating of the raw materials in various parts of the carbonization casing 1, enhancing the uniformity of the carbonization treatment, improving the carbonization efficiency, and at the same time improving the qualified rate of the carbonized finished products.
