Description

Technical Field

[0001] This utility model relates to the field of tube furnace technology, and more specifically, to a rotary tube furnace assembly. Background Technology

[0002] Rotary tube furnaces, as a highly efficient and advanced heat treatment equipment, possess unique advantages in high-temperature uniform heating and precise temperature control. Their indispensable importance lies in various industrial fields, particularly in the ceramics industry, where their application is widespread and profound. The firing process of ceramic products is a process with extremely strict requirements on temperature and time. To ensure that ceramic products meet the expected quality standards, such as hardness, density, color, and gloss, the uniformity and stability of temperature distribution during firing must be guaranteed. This is precisely the area where rotary tube furnaces excel. Typically, the rotation of a tube furnace relies entirely on an independent motor driving the furnace tubes through a transmission device (such as gears, belts, or chains). While the motor-driven rotation system provides stable rotation, ensuring uniform heating and effective material mixing, long-term reliance on the motor to adjust the rotation speed means that the motor needs to constantly change its operating state. This not only increases energy consumption but may also shorten the motor's lifespan. Therefore, improvements and optimizations are necessary. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a rotary tube furnace assembly with the advantages of variable speed adjustment and automatic tilting.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a rotary tube furnace assembly, comprising a lower housing, an upper housing hinged to the top of the lower housing, a flip cover hinged to the top of the upper housing, a furnace tube rotatably mounted inside the upper housing, a large gear, a small gear, and a medium gear fixedly mounted on the outer wall of the furnace tube, a motor fixedly mounted on the left outer wall of the upper housing, a shaped rod fixedly mounted on the output shaft of the motor, the right end of the shaped rod rotatably connected to the left outer wall of the upper housing, and a gear assembly slidably sleeved on the outer wall of the shaped rod, the gear assembly meshing with the small gear.

[0005] As a preferred technical solution of this utility model, a rectangular groove is provided on the top of the lower box, and a hydraulic cylinder two is hinged to the bottom inner wall of the rectangular groove. The output shaft of the hydraulic cylinder two is hinged to the bottom outer wall of the upper box.

[0006] As a preferred embodiment of this utility model, a fixing block is fixedly installed on the left outer wall of the upper housing, a rotating rod is rotatably installed on the inner wall of the fixing block, a gear and a connecting rod are fixedly sleeved on the outer wall of the rotating rod, a U-shaped block is hinged to the front of the connecting rod, the inner wall of the U-shaped block is slidably connected to the gear assembly, a hydraulic cylinder is fixedly installed on the left outer wall of the upper housing, a rack is fixedly installed on the output shaft of the hydraulic cylinder, and the rack meshes with the gear.

[0007] As a preferred embodiment of this utility model, the cross-section of the irregular rod is composed of a circle plus two protrusions, and the two protrusions are symmetrically distributed.

[0008] As a preferred embodiment of this utility model, the gear assembly consists of a medium gear, a large gear, and a small gear, and the gear assembly meshes with the medium gear, the small gear, and the large gear in sequence.

[0009] As a preferred embodiment of this utility model, the large gear, small gear, medium gear and furnace tube rotate at the same speed.

[0010] As a preferred embodiment of this utility model, a control console is fixedly installed on the front of the lower housing, and a vacuum pressure gauge is fixedly installed on the left end of the furnace tube.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model, by setting up three gears with different diameters and numbers of teeth—a large gear, a small gear, and a medium gear—allows the furnace tube to reach different rotational speeds when the gear assembly meshes with different gears. The device can adapt to different process requirements, such as chemical reactions requiring different heating rates or stirring speeds. Compared to traditional devices, this improves the adaptability and versatility of the equipment. Since the rotational speed can be changed by replacing the meshing gears, the same device can adapt to various working scenarios. This reduces the investment required by enterprises for different specifications of equipment, lowering costs. Moreover, operators only need to simply adjust the meshing relationship between the gear assembly and different gears to adjust the rotational speed. Compared to the complex operations required in traditional devices, such as adjusting the motor speed or replacing the transmission belt, this design greatly simplifies the operation process.

[0013] 2. This utility model utilizes the second hydraulic cylinder to drive the upper chamber to tilt, facilitating material loading, unloading, and cleaning. Traditional tube furnaces often require complex procedures for adding or removing materials, such as opening the furnace door or using specialized tools. However, with this tilting device, materials can slide or pour in naturally without additional tools or complicated steps. This significantly saves time and reduces operational difficulty, allowing operators to work more easily. During heating, residues or impurities may accumulate inside the tube furnace. If not cleaned promptly, these substances can damage the equipment or affect heating efficiency. The second hydraulic cylinder allows operators to tilt or tilt the furnace at a certain angle, enabling residues to slide or pour out easily, greatly simplifying the cleaning process.

[0020] 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.

[0021] like Figures 1 to 5As shown, this utility model provides a rotary tube furnace assembly, including a lower housing 1, an upper housing 2 hinged to the top of the lower housing 1, a flip cover 3 hinged to the top of the upper housing 2, a furnace tube 4 rotatably installed inside the upper housing 2, a large gear 5, a small gear 6 and a medium gear 7 respectively fixedly installed on the outer wall of the furnace tube 4, a motor 8 fixedly installed on the left outer wall of the upper housing 2, a special-shaped rod 9 fixedly installed on the output shaft of the motor 8, the right end of the special-shaped rod 9 rotatably connected to the left outer wall of the upper housing 2, and a gear assembly 18 slidably sleeved on the outer wall of the special-shaped rod 9, the gear assembly 18 meshing with the small gear 6.

[0022] By setting up three gears with different diameters and numbers of teeth—large gear 5, small gear 6, and medium gear 7—the furnace tube 4 can reach different speeds when the gear assembly 18 meshes with different gears. The device can adapt to different process requirements, such as chemical reactions requiring different heating rates or stirring speeds. Compared with traditional devices, this improves the adaptability and versatility of the equipment. Since the speed can be changed by changing the meshing gears, the same device can adapt to a variety of different working scenarios. This reduces the investment of enterprises in different specifications of equipment and lowers costs. Moreover, operators only need to simply adjust the meshing relationship between the gear assembly 18 and different gears to adjust the speed. Compared with the complex operations that may require adjusting the motor speed or changing the transmission belt in traditional devices, this design greatly simplifies the operation process.

[0023] The operator first starts motor 8. The output shaft of motor 8 drives the shaped rod 9 to rotate, and the shaped rod 9 drives the gear assembly 18 to rotate. In the initial state, the gear assembly 18 meshes with the small gear 6, thereby driving the small gear 6 to rotate. The small gear 6 drives the furnace tube 4 to rotate. When it is necessary to change the speed of the furnace tube 4, the operator can start hydraulic cylinder 10. The output shaft of hydraulic cylinder 10 extends and retracts, driving rack 11 to move together. Rack 11 meshes with gear 14, driving gear 14 to rotate. Gear 14 drives rotating rod 13 to rotate. Rotating rod 13 drives connecting rod 16 to rotate. The hinge design between connecting rod 16 and C-shaped block 17 drives C-shaped block 17 to move horizontally. C-shaped block 17 drives gear assembly 18 to move together, so that gear assembly 18 meshes with large gear 5 or medium gear 7, thereby achieving the purpose of speed change.

[0024] The lower housing 1 has a rectangular groove 19 on its top, and a hydraulic cylinder 20 is hinged to the bottom inner wall of the rectangular groove 19. The output shaft of the hydraulic cylinder 20 is hinged to the bottom outer wall of the upper housing 2.

[0025] By activating hydraulic cylinder 20, the extension and retraction of hydraulic cylinder 20 drives the upper housing 2 to tilt, thus facilitating the loading, unloading, and cleaning of materials. Traditional tube furnaces often require complex procedures for adding or removing materials, such as opening the furnace door or using specialized tools. However, with this tilting device, materials can slide or be poured in naturally without additional tools or complicated steps. This not only saves time but also reduces operational difficulty, allowing operators to work more easily. During the heating process, residues or impurities may accumulate inside the tube furnace. If these substances are not cleaned promptly, they may damage the equipment or affect the heating effect. Hydraulic cylinder 20 allows operators to tilt or tilt the furnace to a certain angle, allowing residues to easily slide or be poured out, greatly simplifying the cleaning process.

[0026] When the operator decides to pour out the material or clean the furnace tube 4, simply start the hydraulic cylinder 20. Once the hydraulic cylinder 20 starts working, its telescopic function will drive the upper box 2 to tilt as a whole. This tilting action is smooth and controllable. The tilting angle and speed can be adjusted as needed to ensure that the material can be poured out smoothly, while avoiding unnecessary damage to the equipment.

[0027] A fixing block 12 is fixedly installed on the left outer wall of the upper housing 2. A rotating rod 13 is rotatably installed on the inner wall of the fixing block 12. A gear 14 and a connecting rod 16 are fixedly sleeved on the outer wall of the rotating rod 13. A U-shaped block 17 is hinged to the front of the connecting rod 16. The inner wall of the U-shaped block 17 is slidably connected to the gear assembly 18. A hydraulic cylinder 10 is fixedly installed on the left outer wall of the upper housing 2. A rack 11 is fixedly installed on the output shaft of the hydraulic cylinder 10. The rack 11 meshes with the gear 14.

[0028] By activating hydraulic cylinder 10, the output shaft of hydraulic cylinder 10 extends and retracts, driving rack 11 to move together. Rack 11 meshes with gear 14, causing gear 14 to rotate. Gear 14 drives rotating rod 13 to rotate, and rotating rod 13 drives connecting rod 16 to rotate. The hinge design between connecting rod 16 and U-shaped block 17 causes U-shaped block 17 to move horizontally. U-shaped block 17 drives gear assembly 18 to move together, so that gear assembly 18 meshes with different gears to achieve the purpose of speed change.

[0029] Among them, the cross-section of the irregular rod 9 is composed of a circle plus two protrusions, and the two protrusions are symmetrically distributed.

[0030] By incorporating a protrusion, the protrusion design provides more stable and precise transmission when the irregular rod 9 moves in conjunction with its gear assembly 18. The increased contact area between the protrusion and the gear assembly 18 reduces the possibility of slippage and makes the movement more reliable and accurate.

[0031] The gear assembly 18 consists of a medium gear 7, a large gear 5, and a small gear 6, and the gear assembly 18 meshes with the medium gear 7, the small gear 6, and the large gear 5 in sequence.

[0032] By changing the meshing of gear assembly 18 with gears of different numbers of teeth and diameters, the transmission ratio of furnace tube 4 can be easily adjusted, allowing the rotation speed of furnace tube 4 to be adjusted according to different process requirements to meet the heating and reaction requirements of different materials.

[0033] Among them, the large gear 5, the small gear 6, the medium gear 7 and the furnace tube 4 rotate at the same speed.

[0034] By ensuring that all gears rotate at the same speed, when the speed needs to be adjusted, the gear assembly 18 can smoothly mesh with the required large gear 5, small gear 6, and medium gear 7, thereby driving them to rotate.

[0035] Among them, a control console 21 is fixedly installed on the front of the lower box 1, and a vacuum pressure gauge 22 is fixedly installed on the left end of the furnace tube 4.

[0036] By setting up the control panel 21 and the vacuum pressure gauge 22, operators can easily control various parameters of the furnace body, such as temperature, rotation speed, and heating time, on a single interface, greatly improving the convenience and efficiency of operation. The vacuum pressure gauge 22 can monitor the vacuum or pressure value inside the furnace tube 4 in real time, providing operators with important process parameters.

[0037] Working principle and usage process of this utility model:

[0038] The operator first starts motor 8. The output shaft of motor 8 drives the shaped rod 9 to rotate, and the shaped rod 9 drives the gear assembly 18 to rotate. In the initial state, the gear assembly 18 meshes with the small gear 6, thereby driving the small gear 6 to rotate. The small gear 6 drives the furnace tube 4 to rotate. When it is necessary to change the speed of the furnace tube 4, the operator can start hydraulic cylinder 10. The output shaft of hydraulic cylinder 10 extends and retracts, driving rack 11 to move together. Rack 11 meshes with gear 14, driving gear 14 to rotate. Gear 14 drives rotating rod 13 to rotate. Rotating rod 13 drives connecting rod 16 to rotate. The hinge design between connecting rod 16 and C-shaped block 17 drives C-shaped block 17 to move horizontally. C-shaped block 17 drives gear assembly 18 to move together, so that gear assembly 18 meshes with large gear 5 or medium gear 7, thereby achieving the purpose of speed change.

[0039] When the operator decides to pour out the material or clean the furnace tube 4, simply start the hydraulic cylinder 20. Once the hydraulic cylinder 20 starts working, its telescopic function will drive the upper box 2 to tilt as a whole. This tilting action is smooth and controllable. The tilting angle and speed can be adjusted as needed to ensure that the material can be poured out smoothly, while avoiding unnecessary damage to the equipment.
