Description

Technical Field

[0001] The utility model belongs to the field of tubular furnaces, and in particular relates to a tubular furnace which is convenient for loading materials. Background Art

[0002] A tube furnace is a device used for high-temperature experiments and material processing, and is widely used in materials science, chemistry, metallurgy, electronics, and other research fields. Its key feature is its long, narrow heating tube, which is commonly used for processes such as gas-controlled heat treatment, chemical reactions, and sintering. Tube furnaces are typically made of high-temperature-resistant materials (such as ceramics or high-temperature alloys) to withstand high temperatures, and are typically hollow inside to accommodate sample placement and gas flow.

[0003] When heating materials, traditional tube furnaces mostly use a hopper to feed the materials, and the materials are discharged into the tube furnace through the hopper by gravity. During this period, the hopper of the traditional tube furnace does not have an efficient material discharge function, so the materials need to be discharged slowly. If the discharge speed is too fast, the materials will accumulate in the hopper. When the materials accumulate in the hopper, especially for granular, powdery or sticky materials, they may form accumulations due to gravity, resulting in the material not being able to flow smoothly, resulting in uneven material discharge, which affects the heating effect and heating consistency in the furnace, and requires frequent human intervention to clear the blockage. Therefore, a tube furnace that is easy to load is proposed to solve the above problems. Utility Model Content

[0011] As a further improvement of the present invention, two vertical frames are installed on the upper end surface of the support beam and transmission rods are rotatably provided in the two vertical frames. A rotating motor is installed on the side of one of the vertical frames, and the output end of the rotating motor extends to be connected to one end of the transmission rod.

[0012] As a further improvement of the present invention, the end of the transmission rod passes through the vertical frame and is connected to a secondary bevel gear; a main bevel gear is sleeved on the outside of the top end of the stirring rod, and the main bevel gear is meshed with the secondary bevel gear.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0022] Depend on Figure 1-4 Provided is a tubular furnace that is convenient for loading materials, comprising a tubular furnace body 1;

[0023] The tubular furnace body 1 is connected to a silo pipe 2, and a material stirring assembly 3 is installed on the upper end of the silo pipe 2;

[0024] The material mixing assembly 3 includes a material discharge pipe 31 installed outside the silo pipe 2, a silo hopper 32 is provided outside the material discharge pipe 31, and a mounting pipe beam 33 is installed around the silo hopper 32;

[0025] The upper end surface of the mounting pipe beam 33 is supported by a support beam 34, which is arranged in a door-shaped manner and is erected above the mounting pipe beam 33. A ball bearing tube 35 is installed in the middle section of the support beam 34, and a stirring rod 36 is rotated in the ball bearing tube 35.

[0026] A plurality of stirring spiral blades 37 are disposed around the outside of the stirring rod 36 . The stirring spiral blades 37 are vertically arranged and extend into the interior of the material discharge pipe 31 .

[0027] In this embodiment, in actual use, through the mutual cooperation of multiple structures in the material stirring assembly 3, when the material enters the material stirring assembly 3, the material can be stirred by the rotating stirring rod 36 and the stirring spiral blade 37, so that the material can enter the silo pipe 2 more evenly, and then pass through the silo pipe 2 into the tubular furnace body 1 for heat treatment operation; compared with the traditional direct loading method, the present application adds a material stirring assembly 3 above the silo pipe 2, so that the material stirring assembly 3 can effectively break the accumulation of materials, reduce dead corners formed by gravity, and ensure that the material can flow out smoothly, thereby realizing stable loading of the tubular furnace body 1, and at the same time, the stirring of the material stirring assembly 3 can make the material evenly distributed in the silo pipe 2, avoiding uneven feeding due to stratification or unevenness of the material, and further improving the heat treatment operation of the tubular furnace body 1 on the material.

[0028] Specifically, refer to Figure 4 The material discharge pipe 31 is connected to the silo pipe 2; a plurality of support rods 312 are installed inside the material discharge pipe 31, and the plurality of support rods 312 jointly support a support shaft 313, and a deep groove ball bearing tube 314 is assembled in the support shaft 313, and a deep groove ball bearing is installed in the deep groove ball bearing tube 314 and rotates with the bottom end of the stirring rod 36.

[0029] In this embodiment, in actual use, the plurality of support rods 312 provided can be used to install the support shaft 313 and the deep groove ball bearing tube 314; Figure 4 As shown in the figure, the deep groove ball bearing tube 314 is located at the center of the material discharge pipe 31, and the deep groove ball bearing tube 314 rotates in conjunction with the stirring rod 36, so that when the stirring rod 36 rotates, the deep groove ball bearing member arranged in the deep groove ball bearing tube 314 can provide the stirring rod 36 with a more stable rotation, thereby avoiding vibration and jamming of the stirring rod 36 during rotation.

[0030] Specifically, refer to Figure 2-3 Two vertical frames are installed on the upper end surface of the support beam 34, and a transmission rod 310 is rotatably provided in the two vertical frames. A rotating motor 39 is installed on the side of one of the vertical frames, and the output end of the rotating motor 39 extends and is connected to one end of the transmission rod 310.

[0031] In this embodiment, the vertical frame on the upper end surface of the support beam 34 can be used to install the rotating motor 39 and the transmission rod 310; during use, the user connects the power supply to the rotating motor 39 so that the rotating motor 39 can drive the transmission rod 310 to rotate.

[0032] Furthermore, the transmission rod 310 is an existing mature structural component, and its power connection method is existing technology, and the control circuit can be implemented through simple programming by technicians in this field. It is common knowledge in this field and is only used without modification, so the control method and circuit connection will not be described in detail.

[0033] Specifically, refer to Figure 2-3 The end of the transmission rod 310 passes through the vertical frame and is connected to the secondary bevel gear 311; the main bevel gear 38 is sleeved on the outside of the top of the stirring rod 36, and the main bevel gear 38 is meshed with the secondary bevel gear 311.

[0034] In this embodiment, during use, when the transmission rod 310 is rotating, the secondary bevel gear 311 located at its end can drive the main bevel gear 38 meshing with the secondary bevel gear 311 to rotate synchronously. When the main bevel gear 38 is rotating, the stirring rod 36 connected thereto can drive the stirring spiral blade 37 to rotate. Through the rotation of the stirring spiral blade 37, the material in the silo hopper 32 and the material discharge pipe 31 can evenly enter the silo pipe 2, so that the material enters the tubular furnace body 1 through the silo pipe 2 to complete the loading operation.

[0035] Furthermore, through the meshing arrangement between the main bevel gear 38 and the secondary bevel gear 311, the material stirring assembly 3 can allow power to be transmitted between different axial directions, thereby achieving smooth stirring movement, thereby ensuring more stable stirring of the material and reducing vibration and noise.

[0036] Specifically, refer to Figure 1-3 The silo bucket 32 ​​is arranged in an inclined silo shape and is integrated with the material discharge pipe 31; the mounting pipe beam 33 is welded to the top side of the silo bucket 32.

[0037] In this embodiment, the inclined hopper 32 can better supply materials into the material discharge pipe 31, thereby completing the loading operation.

[0038] The utility model is a tube furnace that is easy to load:

[0039] Step 1: In actual use, when the user needs to use the tubular furnace body 1 to perform heat treatment on the material, the user pours the material to be processed into the material stirring assembly 3, and then drives the material stirring assembly 3 to cause the material stirring assembly 3 to efficiently stir the material, thereby achieving efficient material feeding operation by stirring the material, so that the tubular furnace body 1 can perform heat treatment on the material;

[0040] Step 2: When driving the material stirring assembly 3, the user controls the material to fall and enter the silo hopper 32. At this time, the tilting bucket setting of the silo hopper 32 allows the material to fall into the silo hopper 32 by gravity. Then the user connects the power supply to the rotating motor 39 so that the rotating motor 39 can drive the transmission rod 310 to rotate. When the transmission rod 310 rotates, the secondary bevel gear 311 at its end can drive the main bevel gear 38 meshing with the secondary bevel gear 311 to rotate synchronously. When the main bevel gear 38 rotates, the stirring rod 36 connected thereto can drive the stirring spiral blade 37 to rotate. Therefore, through the rotation of the stirring spiral blade 37, the material in the silo hopper 32 and the material discharge pipe 31 can evenly enter the silo pipe 2, and then enter the tubular furnace body 1 through the silo pipe 2 to complete the heat treatment.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
