Description
Technical Field
[0001] The utility model relates to a drying kiln, specifically a drying kiln for coal-based columnar activated carbon. Background Art
[0002] In the production process of activated carbon, the drying link plays a crucial role. Activated carbon, as a porous carbon material with extremely high adsorption capacity, every step in its production process is of great importance, and the drying link is a key step concerning the product quality and performance. Most traditional drying kilns adopt the static drying method, that is, placing the activated carbon in a fixed kiln body and evaporating water by heating. However, this method has a significant drawback: due to the stacking method of activated carbon and the position limitation of the heating source, it often leads to uneven heating of the activated carbon. This uneven heating not only affects the drying quality of the product, making some activated carbon fail to reach the ideal drying degree, but also reduces the overall drying efficiency, increasing the production cost and time cost.
[0003] To overcome this problem, the activated carbon production industry has been actively exploring and researching more advanced and efficient drying technologies. In this process, with the rapid development of industrial technology, the rotary drying technology has gradually emerged and been introduced into the production of activated carbon. The main feature of this technology is to ensure that each piece of activated carbon can be evenly exposed to the heat source by continuously and stably rotating the drying kiln body, thereby achieving uniform heating. This dynamic drying method can not only significantly improve the drying efficiency, enabling the activated carbon to reach the ideal drying state in a shorter time, but also greatly enhance the uniformity of the drying effect, ensuring that each piece of activated carbon has excellent performance.
[0004] However, the design and manufacture of a rotary drying kiln are not easy, and there are many technical challenges in the process. First of all, how to ensure the stability of the drying kiln body during continuous rotation is an urgent problem to be solved. After all, only stable rotation can ensure the uniform heating of the activated carbon, otherwise it may lead to poor drying effect or even equipment damage. Secondly, how to simplify the movement and fixing operations of the equipment is also an important technical problem. In the actual production process, the drying kiln may need to be moved frequently to adapt to different production environments and requirements. Therefore, the mobility and convenience of the equipment are equally important.
[0005] To solve the above technical problems and further improve the drying effect and production efficiency of activated carbon, we propose an innovative technical solution for a drying kiln for coal-based columnar activated carbon. Summary of the Utility Model
[0006] The technical problem to be solved by the utility model is to overcome the above-mentioned technical defects and provide a drying kiln for coal-based columnar activated carbon.
[0007] To solve the above technical problems, the technical solution provided by the present utility model is a coal-based columnar activated carbon drying kiln, which includes a rotary support mechanism and a rotary drying kiln body arranged on the rotary support mechanism.
[0008] The rotary support mechanism includes a support frame body. On both sides of the support frame body, support rotating rollers are symmetrically arranged in a rotational manner. An annular notch is provided on the support rotating roller, and the number of the annular notches is several and they are evenly arranged along the extending direction of the support rotating roller. A speed reduction drive device is provided on the support frame body, and a transmission connection is arranged between the speed reduction drive device and the support rotating roller.
[0009] A limiting ring body is provided on the outer wall of the rotary drying kiln body, and the outer wall of the rotary drying kiln body is in contact with the outer wall of the support rotating roller. The limiting ring body provided on the outer wall of the rotary drying kiln body is located at the annular notch provided on the support rotating roller, playing a role in limiting and ensuring the stability of the rotary drying kiln body during rotation.
[0010] As an improvement, the projection of the support frame body in the top view direction is rectangular.
[0011] As an improvement, support feet are fixedly provided at the four corners on the lower side of the support frame body.
[0012] As an improvement, traveling wheels are symmetrically arranged in a rotational manner on both sides of one side of the support frame body. When the support frame body is in a horizontal position, the lowest height of the traveling wheels is higher than the lowest height of the support feet. Notches are symmetrically arranged on both sides of the other side of the support frame body. An L-shaped plate body is rotatably arranged in the notches. The bent part of the L-shaped plate body is rotatably matched with the notches. An auxiliary wheel is provided on the lower plate of the L-shaped plate body, and the L-shaped plate body further includes an upper limiting plate.
[0013] As an improvement, the included angle formed by the L-shaped plate body is an acute angle.
[0014] The advantages of the present utility model compared with the prior art are as follows: the rotation function of the rotary drying kiln body: the rotary drying kiln body is installed on the rotary support mechanism and can rotate freely.
[0015] The cooperation between the limiting ring body and the support rotating roller: the limiting ring body is in close contact with the outer wall of the support rotating roller and is accurately located at the annular notch on the support rotating roller. The limiting ring body ensures that the drying kiln body does not deviate from the track during rotation.

[0026] Combined with the attached drawings, a drying kiln for coal-based columnar activated carbon includes a rotating support mechanism 1 and a rotating drying kiln body 2 arranged on the rotating support mechanism 1;
[0027] The rotating support mechanism 1 includes a support frame body 11. The projection of the support frame body 11 in the top view direction is rectangular. On both sides of the support frame body 11, support rotating rollers 12 are rotatably arranged in a counter-supporting manner. An annular notch 13 is provided on the support rotating roller 12. The number of the annular notches 13 is several and they are evenly arranged along the extending direction of the support rotating roller 12. A speed reduction drive device 14 is provided on the support frame body 11, and the speed reduction drive device 14 is in transmission connection with the support rotating roller 12.
[0028] At the four corners of the lower side of the support frame body 11, support feet 15 are fixedly provided. On both sides of one side of the support frame body 11, traveling wheels 16 are arranged in a counter-supporting manner. When the support frame body 11 is in a horizontal position, the lowest height of the traveling wheels 16 is higher than the lowest height of the support feet 15. On both sides of the other side of the support frame body 11, notches 17 are symmetrically provided. An L-shaped plate body 18 is rotatably arranged in the notches 17. The bent part of the L-shaped plate body 18 is rotatably matched with the notches 17. The included angle formed by the L-shaped plate body 18 is an acute angle. An auxiliary wheel 19 is provided on the lower plate of the L-shaped plate body 18. The L-shaped plate body 18 further includes an upper limiting plate 110.
[0029] When the support frame body 11 is in a placed state, the support feet 15 support the ground, the traveling wheels 16 are suspended, and the upper limiting plate 110 on the L-shaped plate body 18 is separated from the top of the notches 17, and the auxiliary wheel 19 provided on the lower plate of the L-shaped plate body 18 does not play a supporting role.
[0030] When the support frame body 11 is in a placed and moving state, the traveling wheels 16 contact the ground, the upper limiting plate 110 on the L-shaped plate body 18 contacts the top of the notches 17. Since the included angle formed by the L-shaped plate body 18 is an acute angle, the auxiliary wheel 19 provided on the lower plate of the L-shaped plate body 18 plays a supporting role, the support feet 15 are separated from the ground, and the traveling wheels 16 and the auxiliary wheel 19 play a role in moving the support frame body 11.
[0031] On the outer wall of the rotary drying kiln body 2, there is a limiting ring body 21. The outer wall of the rotary drying kiln body 2 is in contact with the outer wall of the supporting rotating roller 12. The limiting ring body 21 provided on the outer wall of the rotary drying kiln body 2 is located at the annular notch 13 provided on the supporting rotating roller 12, which plays a role in limiting and ensures the stability of the rotary drying kiln body 2 during rotation.
[0032] This drying kiln mainly consists of two major parts: a rotary support mechanism 1 and a rotary drying kiln body 2.
[0033] I. Rotary support mechanism 1:
[0034] The rotary support mechanism 1 is the basic part of the drying kiln. It mainly includes a support frame body 11. The projection of this support frame body 11 in the top view direction is rectangular, which is stable and has strong load-bearing capacity.
[0035] On both sides of the support frame body 11, supporting rotating rollers 12 are rotatably arranged in a counter-supporting manner. These supporting rotating rollers 12 are specially designed with annular notches 13, and the number of these annular notches 13 is several, which are evenly arranged along the extending direction of the supporting rotating rollers 12 to better cooperate with the rotation of the drying kiln body.
[0036] In addition, a speed reduction drive device 14 is also equipped on the support frame body 11. This device is in transmission connection with the supporting rotating roller 12 and can provide stable and controllable power for the rotation of the drying kiln body.
[0037] II. The moving and fixing functions of the support frame body 11:
[0038] Support feet 15 are fixed at the four lower corners of the support frame body 11 to stably support the entire frame body statically. At the same time, a traveling wheel 16 is arranged in a counter-supporting manner on one side of the support frame body 11. When the support frame body 11 is in a horizontal position, the lowest height of the traveling wheel 16 is higher than the lowest height of the support feet 15. This design is to facilitate lifting the frame body to make the traveling wheel 16 contact the ground when the frame body needs to be moved.
[0039] On the other side of the support frame body 11, notches 17 are symmetrically arranged. L-shaped plate bodies 18 are rotatably arranged in these notches 17. The bent part of the L-shaped plate body 18 is in rotational cooperation with the notch 17, and the included angle formed by it is an acute angle. An auxiliary wheel 19 is also provided on the lower plate of the L-shaped plate body 18, and an upper limiting plate 110 is included.
[0040] When the support frame 11 is in the placed state, the support feet 15 support the ground and the walking wheels 16 are suspended. At this time, the upper limit plate 110 on the L-shaped plate body 18 is separated from the top of the notch 17, so the auxiliary wheels 19 do not play a supporting role. When it is necessary to move the support frame 11, just tilt the frame slightly to make the walking wheels 16 contact the ground. At the same time, the upper limit plate 110 of the L-shaped plate body 18 will contact the top of the notch 17. Since the included angle formed by the L-shaped plate body 18 is an acute angle, the auxiliary wheels 19 will play a supporting role at this time, lifting the support feet 15 off the ground, so that the support frame 11 can be conveniently moved through the walking wheels 16 and the auxiliary wheels 19.
[0041] III. Rotating drying kiln body 2:
[0042] The rotating drying kiln body 2 is the main working part placed on the rotary support mechanism 1. A limit ring body 21 is provided on its outer wall, and this limit ring body 21 contacts the outer wall of the support rotating roller 12. Particularly, the limit ring body 21 is located at the annular notch 13 on the support rotating roller 12. Such a design not only plays a limiting role but also ensures the stability of the rotating drying kiln body 2 during rotation.
[0043] Generally speaking, this coal-based columnar activated carbon drying kiln has a clever structure and is convenient to use. It can not only carry out drying operations stably but also move its position conveniently when needed.
[0044] The rotating function of the rotating drying kiln body 2: The rotating drying kiln body 2 is installed on the rotary support mechanism 1 and can rotate freely. This design enables the activated carbon in the drying kiln to be heated evenly, thereby improving the drying efficiency and effect. Through continuous rotation, it is ensured that each piece of activated carbon can be evenly exposed to the heat source, avoiding the problem of uneven drying that may occur in the traditional static drying method.
[0045] The cooperation between the limit ring body 21 and the support rotating roller 12: The limit ring body 21 is in close contact with the outer wall of the support rotating roller 12 and is accurately located at the annular notch 13 on the support rotating roller 12. The limit ring body 21 ensures that the drying kiln body does not deviate from the track during rotation, enhancing the stability of the drying kiln body during high-speed rotation.
[0046] The static stability of the support frame 11: When the support frame 11 is in the placed state, the support feet 15 firmly support the ground, ensuring that the entire device does not move when static. This design not only guarantees the safety of the device but also avoids potential risks caused by accidental movement. At the same time, the firm support also provides a reliable platform for the drying operation.
[0047] Mobility of the L-shaped plate body 18 and the auxiliary wheel 19: The design of the L-shaped plate body 18 is very ingenious. The acute angle formed by it enables the auxiliary wheel 19 to easily lift the support foot 15 off the ground when the device needs to be moved. This design greatly simplifies the movement process of the device, allowing the user to easily move the entire support frame 11 through the walking wheels 16 and the auxiliary wheel 19.
[0048] The above describes the present utility model and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and, without departing from the gist of the creation of the present utility model, design similar structural modes and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present utility model.
