Description

Technical Field

[0001] The utility model relates to the technical field of rotary kilns, in particular to a rotary kiln used for producing camphor fertilizers. Background Art

[0002] The residue left after extracting camphor leaves can be used as a raw material for organic fertilizer, known as camphor fertilizer. During the drying process, this process is typically performed in a rotary kiln. A rotary kiln, a rotating calcining kiln (commonly known as a rotary kiln), resembles a rotating bed and can utilize excess heat within the production system to dry the material. However, over long periods of use, materials can become lodged in the kiln's inner walls. This adhesion, when significant, reduces the kiln's efficiency and increases power consumption. Currently, cleaning is often performed by manually knocking on the outer walls after shutting down the kiln. This current cleaning method is labor-intensive, and any downtime can impact production schedules. Utility Model Content

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances. Example

[0024] A rotary kiln for producing camphor fertilizer includes a rotary kiln 9. A bracket 1 is provided on the side of the rotary kiln 9, and a knocking device is provided on the bracket 1. A driving member is provided on the circumferential side wall of the rotary kiln 9 for driving the knocking device to strike the surface of the rotary kiln 9 during the rotation of the rotary kiln 9.

[0025] In this embodiment, Figure 1As shown, the rotary kiln 9 is used to continuously calcine, dry or chemically react materials at high temperatures. Its interior is usually lined with refractory materials to withstand high temperatures and corrosive environments. Through slow rotation, the materials are evenly heated in the kiln, while promoting mixing and chemical reactions between materials. The bracket 1 is fixed to the side of the rotary kiln 9 to provide a stable support structure to ensure that the knocking device can be accurately installed in the required position. The bracket 1 must have sufficient strength and rigidity to withstand the vibration and impact generated by the knocking device when it is working, while maintaining the stability and durability of the structure. The bracket 1 adopts a door-type frame, the rotary kiln 9 is located on the inner side of the door-shaped bracket 1. Multiple brackets 1 can be set along the length direction of the rotary kiln 9, and then the knocking device on the bracket 1 can realize multi-point knocking on the rotary kiln 9, which has a better descaling effect. Under the action of the driving member, the knocking device periodically strikes the circumferential side wall of the rotary kiln 9 to remove the dirt and slag attached to the kiln wall. The driving member is a key component connecting the knocking device and the rotary kiln 9, and is responsible for synchronously driving the knocking device to work during the rotation of the rotary kiln 9. The knocking and descaling process does not require manual cleaning of adhesives, which reduces manual labor intensity. At the same time, there is no need to stop work for cleaning, ensuring the normal progress of production.

[0026] Furthermore, the knocking device is distributed above the top of the rotary kiln 9. Specifically, the cross section of the rotary kiln 9 is circular, and the knocking device is arranged just above the vertical diameter, so that the surface of the rotary kiln 9 can be hit vertically.

[0027] Furthermore, the knocking device includes a fixed cylinder 4 and a knocking head 2. The upper end of the fixed cylinder 4 is fixed to the top of the bracket 1. The knocking head 2 is connected to a guide rod 3. The guide rod 3 and the fixed cylinder 4 are slidably connected. The knocking head 2 is located below the fixed cylinder 4. A limit plate 6 is provided on one end of the guide rod 3 located in the fixed cylinder 4. During the rotation of the rotary kiln 9, the driving member drives the knocking head 2 to gradually move upward. After the driving member is separated from the knocking head 2, the knocking head 2 falls back under the action of gravity and knocks the surface of the rotary kiln 9.

[0028] Specifically, such as Figure 1As shown, the upper end of the fixed cylinder 4 is fixed on the top of the bracket 1, providing a stable support for the entire knocking device. The fixed cylinder 4 is designed with a space for the sliding of the guide rod 3 to ensure that the movement trajectory of the knocking head 2 in the vertical direction is accurate. The knocking head 2 is the component that actually performs the knocking action. It is located below the fixed cylinder 4 and directly contacts and hits the surface of the rotary kiln 9. The shape and weight of the knocking head 2 need to be accurately calculated to ensure that each knock can generate enough force to effectively remove dirt and slag. The guide rod 3 connects the knocking head 2 and the fixed cylinder 4 to ensure that the knocking head 2 moves smoothly and unobstructed in the axial direction of the fixed cylinder 4. The guide rod 3 and the fixed cylinder 4 are connected in a sliding manner to reduce The friction and resistance during the movement are reduced, and the knocking efficiency is improved. At the same time, the length and diameter of the guide rod 3 need to be adjusted according to actual needs to ensure that the movement trajectory and force of the knocking head 2 meet the requirements. The limit plate 6 is set on one end of the guide rod 3 located in the fixed cylinder 4. The limit plate 6 is used to limit the maximum position of the knocking head 2 during the falling knocking process. The driving member is a component that controls the movement of the knocking head 2 (or indirectly controls the knocking head 2). During the rotation of the rotary kiln 9, the driving member drives the knocking head 2 to move gradually upward (in the direction of the axis of the fixed cylinder 4). When the knocking head 2 is separated from the driving member, due to the action of gravity, it will quickly fall back and drive the knocking head 2 to knock on the surface of the rotary kiln 9.

[0029] During the rotation of the rotary kiln 9, the driving member drives the striking head 2 to gradually move upward. When the striking head 2 rises to a certain position, it loses contact with the driving member. At this time, under the action of gravity, the striking head 2 quickly falls back and is driven by the guide rod 3 to strike the surface of the rotary kiln 9 at a certain speed and force. This process is repeated continuously, thereby achieving the purpose of automatic descaling.

[0030] Furthermore, the striking head 2 is a solid iron sphere.

[0031] Specifically, the iron material has high hardness and wear resistance, and can withstand frequent and high-intensity knocking without being easily damaged. This is especially important for the rotary kiln 9 descaling device that works in harsh environments for a long time. Since the sphere has a uniform mass distribution, it can generate stable and consistent force when knocking, which helps to ensure that each knock can effectively remove dirt and slag on the surface of the rotary kiln 9, thereby improving the descaling efficiency. The spherical-shaped knocking head 2 can more easily adapt to the curvature changes of the surface of the rotary kiln 9, reducing the situation where the knocking effect is weakened or the knocking head 2 is damaged due to shape mismatch. The solid iron sphere structure is relatively simple, and the manufacturing and maintenance costs are low. At the same time, this design also reduces the failures and maintenance difficulties that may be caused by complex structures. Under the action of the driving member, the spherical knocking head 2 can rise rapidly and fall back quickly after being separated from the driving member. Since the sphere has a large mass and inertia, it can generate a large impact force during the falling process, effectively removing dirt and slag.

[0032] Furthermore, the driving member is an inclined guide plate 7, which is evenly distributed around the circumference of the rotary kiln 9. One end of the guide plate 7 is connected to the surface of the rotary kiln 9. During the rotation of the rotary kiln 9, the striking head 2 contacts the guide plate 7 and gradually rises along with the inclination angle of the guide plate 7 until it reaches the highest point after separating from the guide plate 7.

[0033] Specifically, such as Figure 2 and Figure 3 As shown, the guide plate 7 serves as the driving member of the striking head 2. Through its tilt angle, it guides the striking head 2 to gradually rise during the rotation of the rotary kiln 9. When the striking head 2 contacts the guide plate 7, due to the tilt of the guide plate 7, the striking head 2 will be subjected to an upward component of force, thereby following the guide plate 7 to rise. The guide plates 7 are evenly distributed around the circumference of the rotary kiln 9 to ensure that the striking head 2 can be continuously and evenly driven during the rotation of the kiln body. At the same time, the tilt angle and length of the guide plate 7 must be accurately calculated to ensure that the striking head 2 can rise to a suitable height and generate sufficient impact force after separation. When the rotary kiln 9 is stationary or just starting to rotate, the striking head 2 is located below the guide plate 7 and is not in contact with the guide plate 7. As the rotary kiln 9 rotates, the striking head 2 gradually approaches the guide plate 7 and contacts it. Due to the inclination of the guide plate 7, the knocking head 2 is subjected to an upward component of force and begins to gradually rise along the guide plate 7. When the knocking head 2 rises to a certain height, it will lose contact with the guide plate 7. At this time, the knocking head 2 begins to fall back under the action of gravity and hits the surface of the rotary kiln 9 with its own weight and speed, achieving a descaling effect. As the rotary kiln 9 continues to rotate, the knocking head 2 will continuously repeat the above process, achieving continuous knocking and descaling of the kiln surface. The design of the guide plate 7 is relatively simple and easy to manufacture and install. Due to its simple structure, the maintenance and replacement of the guide plate 7 are also relatively easy. Through the continuous knocking of the knocking head 2, the dirt and slag on the surface of the rotary kiln 9 can be effectively removed. This design is applicable to rotary kilns 9 of different specifications and models. It is only necessary to adjust the distribution and inclination angle of the guide plate 7 according to the size of the kiln body.

[0034] Furthermore, an adjusting rod 8 for adjusting the inclination angle of the guide plate 7 is provided between the guide plate 7 and the rotary kiln 9. The guide plate 7 is hinged to the surface of the rotary kiln 9, and the lower end of the adjusting rod 8 is hinged to the surface of the rotary kiln 9. A plurality of fixed plates 10 are provided at intervals along the length direction of the guide plate 7 on both sides. The adjusting rod 8 is connected to the fixed plates 10 at different positions to adjust the inclination angle of the guide plate 7.

[0035] Specifically, such as Figure 3As shown, the adjusting rod 8 is a key component for adjusting the inclination angle of the guide plate 7. By changing the connection point between the adjusting rod 8 and the fixed plate 10 at different positions, the inclination angle of the guide plate 7 relative to the rotary kiln 9 can be adjusted, thereby controlling the height and speed of the knocking head 2. The adjusting rod 8 not only provides an adjustment function, but also enhances the stability of the guide plate 7 through its hinged connection with the rotary kiln 9 and the fixed plate 10, ensuring that the guide plate 7 will not be deformed or shifted due to force during the knocking process. The guide plate 7 is connected to the surface of the rotary kiln 9 in an articulated manner. This connection method allows the guide plate 7 to maintain While maintaining a certain stability, it can rotate around the hinge point at a certain angle. This rotational movement is achieved through the connection adjustment between the adjusting rod 8 and the fixed plate 10. The fixed plates 10 are arranged at intervals on both sides of the guide plate 7, which not only provides a connection point for the adjusting rod 8, but also plays a role in supporting and positioning the guide plate 7. By adjusting the connection between the adjusting rod 8 and the fixed plates 10 at different positions, the inclination angle of the guide plate 7 can be accurately controlled. The presence of the fixed plate 10 also enhances the connection strength between the guide plate 7 and the rotary kiln 9, thereby improving the stability and durability of the entire descaling device. During the installation process, the inclination angle of the guide plate 7 is preliminarily set according to the size of the rotary kiln 9 and the descaling requirements. As the production process proceeds, if it is necessary to adjust the descaling effect according to actual conditions, the inclination angle of the guide plate 7 can be adjusted by changing the connection position of the adjusting rod 8 and the fixed plate 10. During the rotation of the rotary kiln 9, the knocking head 2 contacts the guide plate 7 and gradually rises along its inclination angle until it reaches the highest point after separating from the guide plate 7 and falls back to knock the surface of the rotary kiln 9. By adjusting the inclination angle of the guide plate 7, the rising height and falling speed of the knocking head 2 can be controlled, thereby affecting the descaling effect.

[0036] Furthermore, the adjusting rod 8 is a threaded rod, and a through hole 11 is opened on the fixing plate 10 to allow the adjusting rod 8 to pass through. The adjusting rod 8 passes through the through hole 11 and is connected to the fixing plate 10 through two nuts 12.

[0037] Specifically, such as Figure 2 As shown, the design of the threaded rod allows its position in the through hole 11 of the fixing plate 10 to be precisely adjusted by rotating the nut 12. This fine-tuning mechanism can ensure that the inclination angle of the guide plate 7 reaches the required precise value. The use of two nuts 12 increases the stability of the connection. When the two nuts 12 are properly tightened, the two nuts 12 are respectively located on the upper and lower sides of the fixing plate 10. They will jointly clamp the fixing plate 10 to prevent the adjusting rod 8 from loosening or moving when vibrating or under force. The adjusting top will exceed the top surface of the guide plate 7. Therefore, in order to avoid affecting the knocking head 2, the width of the guide plate 7 is greater than the diameter of the knocking head 2, at least to ensure that the knocking head 2 will not contact the top of the adjusting rod 8.

[0038] Furthermore, an elastic body 5 capable of accelerating the falling speed of the striking head 2 is provided between the limiting plate 6 and the upper end of the fixing tube 4 .

[0039] Furthermore, the elastic body 5 is a spring.

[0040] Specifically, such as Figure 1 As shown, when the striking head 2 follows the guide plate 7 to rise to the highest point and separates from the guide plate 7, the spring will use its elastic potential energy to quickly push the limit plate 6 to move downward along the axis of the fixed cylinder 4, thereby accelerating the falling speed of the striking head 2. This acceleration can make the striking head 2 hit the surface of the rotary kiln 9 at a higher speed, thereby improving the descaling effect. During the rotation of the rotary kiln 9, the striking head 2 contacts the guide plate 7 and gradually rises following its inclination angle. At this time, the spring is in a compressed state and stores elastic potential energy. When the striking head 2 rises to the highest point and separates from the guide plate 7, the spring quickly releases its stored elastic potential energy, pushing the limit plate 6 and the striking head 2 connected thereto to move downward at an accelerated speed. The striking head 2 falls back at a higher speed under the push of the spring and hits the surface of the rotary kiln 9, thereby achieving a descaling effect.

[0041] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Based on the technical essence of the present invention and within the spirit and principles of the present invention, any simple modification, equivalent replacement and improvement of the above embodiment shall still fall within the scope of protection of the technical solution of the present invention.
