Description

Technical Field

[0001] This utility model relates to the field of carbon rod filter material processing technology, and in particular to a multi-stage gradient carbon rod high-temperature sintering furnace. Background Technology

[0002] Carbon rod filter cartridges are an important component in water purifiers used for filtering and purifying water. Their main material is activated carbon, which is typically made from raw materials such as coconut shells, fruit shells, and coal. The performance of carbon rod filter cartridges directly affects the quality and performance of the water purifier. High-temperature sintering, as a key process determining the performance of carbon rods, places increasingly stringent requirements on sintering equipment.

[0003] The existing high-temperature sintering furnace disclosed in patent number CN206064779U consists of a pre-drying zone, a sintering zone, and a cooling zone. The pre-drying zone is equipped with one or more hot air burners, and the sintering zone with two or more hot air burners. A washing tank is located at the bottom of the cooling zone and is connected to an induced draft fan. A blower is located at the top of the cooling zone, injecting air. Paint mist and volatile solvents fall into the washing tank under air pressure, reducing the harm of the paint to the human body and preventing environmental pollution. A partition device is installed between the drying zone and the cooling zone to clearly delineate the areas, avoid heat loss, and facilitate rapid cooling. However, current existing technologies do not adequately guarantee the uniformity of heating of carbon rods during the carbon rod sintering process. During the transfer of carbon rods, it is impossible to effectively heat them from all sides, resulting in temperature differences in different parts of the carbon rod. This affects the consistency of key properties such as density, strength, and conductivity, leading to unstable product quality and a high defect rate. Therefore, how to ensure uniform heating of carbon rods from all sides has become a problem urgently needing to be solved by those skilled in the art. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a multi-stage gradient carbon rod high-temperature sintering furnace.

[0005] This utility model is achieved through the following technical solution:

[0006] A multi-stage gradient carbon rod high-temperature sintering furnace includes a furnace body, a controller on the surface of the furnace body, a conveyor wheel inside the furnace body, an adjustment block on the top surface of the inner wall of the furnace body, a heat insulation plate on the inner wall of the furnace body with equal spacing, a resistance wire on the inner wall of the furnace body, and a temperature sensor on the top surface of the inner wall of the furnace body.

[0007] As can be seen, in the above technical solution, the conveyor wheel is responsible for transporting the carbon rod body, so that it passes through three different stages in the furnace: preheating, sintering and cooling. Multiple arc-shaped adjustment blocks are arranged in an arc shape. Due to the special position of the adjustment blocks, the adjustment blocks cooperate with the carbon rod body to realize the horizontal flipping of the carbon rod body during the conveying process, ensuring that the carbon rod is heated evenly. The heat insulation plates are evenly arranged on the inner wall, dividing the furnace body into a preheating section, a sintering section and a cooling section, effectively reducing the conduction of heat between different areas in the furnace, maintaining the temperature gradient of each section and improving energy utilization efficiency.

[0008] Optionally, in one possible implementation, furnace doors are provided on both sides of the furnace body, and handles are provided on the surface of the furnace doors. It can be seen that in the above technical solution, the furnace doors on both sides of the furnace body facilitate the loading and unloading of the carbon rods. Operators can easily open and close the furnace doors using the handles, which is convenient for operation, improves work efficiency, and also ensures the sealing of the furnace doors when closed, reducing heat loss.

[0009] Optionally, in one possible implementation, an air inlet pipe is provided on one side of the furnace body, and an air outlet pipe is provided on the other side of the furnace body. It can be seen that in the above technical solution, the air inlet pipe is connected to an external fan, and gas is supplied to the cooling section inside the furnace through the air inlet pipe. This air slowly exchanges heat with the carbon rod body that has undergone high-temperature sintering, thereby achieving a slow cooling operation and avoiding quality problems such as cracks and deformation of the carbon rod body due to excessively rapid cooling. The air after heat exchange is then discharged outside the furnace through the air outlet pipe.

[0010] Optionally, in one possible implementation, the bottom surface of the furnace body is provided with support legs, and three temperature sensors are electrically connected to the controller. It can be seen that in the above technical solution, the support legs are used to support the furnace body, maintaining a stable working height. The three temperature sensors are respectively located in the preheating section, sintering section, and cooling section, and are used to collect temperature data in each section. The controller analyzes and processes this data to achieve comprehensive and precise control of the temperature in the three sections of the furnace, ensuring that the temperature in each area meets the process requirements.

[0011] Optionally, in one possible implementation, the surface of the conveyor wheel is provided with a carbon rod body, and the shape and position of the carbon rod body correspond to the shape and position of the adjusting block. It can be seen that in the above technical solution, the carbon rod body is placed on the surface of the conveyor wheel and moves inside the furnace under the drive of the conveyor wheel. The shape and position of the adjusting block correspond to the carbon rod body. During the carbon rod conveying process, the adjusting block contacts the end of the carbon rod and flips it, allowing all parts of the carbon rod to be heated evenly, effectively improving the sintering quality of the carbon rod and reducing quality problems caused by uneven heating.

[0012] Optionally, in one possible implementation, the adjusting block is arc-shaped, and its position is adapted to the position of the conveyor wheel. It can be seen that in the above technical solution, the adjusting block is arc-shaped. When the carbon rod body moves with the conveyor wheel, the arc-shaped adjusting block can cleverly contact the carbon rod body. Utilizing its unique shape characteristics, it provides a suitable flipping force for the carbon rod body, achieving smooth flipping of the carbon rod body, ensuring uniform heating of the carbon rod body throughout the sintering process, and improving the consistency of product performance.

[0013] Optionally, in one possible implementation, the resistance wires are arranged axially symmetrically on the inner wall of the furnace body, and the resistance wires are electrically connected to the controller. It can be seen that in the above technical solution, the resistance wires are the main heating element, generating heat after being energized to provide the necessary thermal energy for the sintering of the carbon rod body. The axially symmetrical arrangement of the resistance wires allows for a more uniform heat distribution within the furnace, avoiding localized overheating. The controller precisely adjusts the heating power of the resistance wires at corresponding positions based on the temperature information fed back from each temperature sensor, thereby achieving precise temperature control within the furnace, meeting the requirements of multi-stage gradient temperature, and improving the sintering quality and production efficiency of the carbon rods.

[0014] The beneficial effects of this utility model are:

[0015] This invention utilizes multiple arc-shaped adjusting blocks. Because these blocks are arranged in an arc shape, and the furnace contains multiple sections of arc-shaped adjusting blocks with different orientations, when the carbon rod moves to the first adjusting block driven by the conveyor wheel, the carbon rod is forced to flip under the obstruction of the adjusting block, receiving heat from all directions. When the carbon rod reaches the end of this adjusting block, due to the space design between the tail end and the first end of the two adjusting blocks, the carbon rod can smoothly transfer and move to another arc-shaped adjusting block arranged in the opposite direction, flipping in the opposite direction. In this way, the carbon rod can move and flip from one side of the furnace to the other during the conveying process. The carbon rod's heating surface continuously changes throughout the conveying process, greatly ensuring the uniformity of heating and effectively avoiding inconsistencies in key properties such as density, strength, and conductivity caused by uneven heating. This significantly improves the sintering quality of the carbon rod, reduces the defect rate, and powerfully promotes the high-quality development of carbon rod production.

[0025] Example 1:

[0026] As shown in the figure, this embodiment provides a multi-segment gradient carbon rod high-temperature sintering furnace, characterized by including a furnace body 1. The furnace body 1 serves as the main structure of the entire sintering furnace, bearing and protecting all internal components. It provides a closed space for the preheating, sintering, and cooling processes of the carbon rod body 12, effectively preventing heat loss and interference from external factors. Furnace doors 3 are provided on both sides of the furnace body 1, and handles 4 are provided on the surface of the furnace doors 3. The furnace doors 3 are located on both sides of the furnace body 1, facilitating the loading and unloading of the carbon rod body 12 by operators. When the furnace doors 3 are closed, they ensure the airtightness of the furnace body 1, reducing heat leakage and maintaining a stable temperature environment inside the furnace. The handles 4 are convenient for operators to grip, easily opening and closing the furnace doors 3, improving operational convenience. A controller 2 is provided on the surface of the furnace body 1. The controller 2 is connected to a temperature sensor 10 and a resistance wire 7, and is the control core of the entire sintering furnace. It receives temperature data fed back by the temperature sensor 10 and precisely adjusts the heating power of the resistance wire 7 according to the preset temperature curve and process requirements, achieving precise control of the furnace temperature.

[0027] The furnace body 1 is equipped with a conveyor wheel 6, which is located inside the furnace body 1. Carbon rod bodies 12 are placed on the surface of the conveyor wheel 6, which rotates under the drive of a motor. The conveyor wheel 6 is responsible for sequentially conveying the carbon rod bodies 12 to the preheating section, sintering section, and cooling section within the furnace, completing the entire sintering process. Simultaneously, it works in conjunction with adjusting blocks 9 to rotate the carbon rod bodies 12. The surface of the conveyor wheel 6 is equipped with the carbon rod bodies 12, and the shape and position of the carbon rod bodies 12 correspond to the shape and position of the adjusting blocks 9. The carbon rod bodies 12 are the processing objects in the sintering furnace. They move and rotate under the action of the conveyor wheel 6 and adjusting blocks 9, undergoing preheating, sintering, and cooling processes to improve performance. When the carbon rod bodies 12 are placed horizontally, they are perpendicular to the conveyor wheel 6 on the horizontal plane, allowing the ends of the carbon rod bodies 12 to contact the arc surface of the arc-shaped adjusting blocks 9, thereby achieving rotation. The top surface of the inner wall of the furnace body 1 is... There is an adjusting block 9, which is arc-shaped and its position is adapted to the position of the conveyor wheel 6. Multiple arc-shaped adjusting blocks 9 are arranged in an arc direction. When the carbon rod body 12 is conveyed by the conveyor wheel 6, it is blocked by the adjusting block 9 at the end, so that it is subjected to a horizontal flipping force. This causes the carbon rod body 12 to flip from one side of the furnace to the other side during the movement. In addition, multiple arc-shaped adjusting blocks 9 with different directions are arranged in the furnace. The space design between the tail end and the first section of two sections of adjusting blocks 9 allows the carbon rod body 12 to be smoothly transferred and moved to another section of arc-shaped adjusting block 9 arranged in the opposite direction for flipping in the opposite direction. In this way, the carbon rod body 12 can move and flip from one side of the furnace body 1 to the other side during the conveying process. The carbon rod body 12 can continuously change the heating surface during the entire conveying process, thereby improving the sintering quality.

[0028] The inner wall of the furnace body 1 is provided with heat insulation plates 8, which are evenly spaced on the inner wall of the furnace body 1. The heat insulation plates 8 are evenly spaced on the inner wall of the furnace body 1, dividing the furnace body 1 into a preheating section, a sintering section and a cooling section. This can effectively block the conduction of heat between different areas in the furnace, maintain the temperature gradient of each section, avoid mutual heat interference, improve energy utilization efficiency, and ensure the smooth progress of each stage of the process. The inner wall of the furnace body 1 is provided with resistance wires 7, which are axially symmetrically arranged on the inner wall of the furnace body 1 and electrically connected to the controller 2. The resistance wires 7 are provided in the preheating section and the sintering section. The resistance wires 7 are the main heating elements. After being energized, the resistance wires 7 generate heat, which provides the required thermal energy for the preheating and sintering of the carbon rod body 12 through radiation and convection. The top surface of the inner wall of the furnace body 1 is provided with temperature sensors 10. The three temperature sensors 10 are electrically connected to the controller 2 respectively. Next, three temperature sensors 10 are respectively installed in the preheating section, sintering section and cooling section to collect temperature data in each section. The controller 2 analyzes and processes the data to achieve comprehensive and precise control of the temperature in the three sections of the furnace, ensuring that the temperature in each area meets the process requirements. The side of the furnace body 1 is provided with an air inlet pipe 5 and the other side of the furnace body 1 is provided with an air outlet pipe 11. The air inlet pipe 5 is connected to an external fan and gas is delivered to the cooling section of the furnace through the air inlet pipe 5. This air slowly exchanges heat with the carbon rod body 12 after high-temperature sintering, thereby achieving slow cooling operation and avoiding quality problems such as cracks and deformation of the carbon rod body 12 due to excessive cooling rate. The air after heat exchange is discharged outside the furnace through the air outlet pipe 11. The bottom surface of the furnace body 1 is provided with a support leg 13, which supports the furnace body 1 and keeps the furnace body 1 at a stable working height.

[0029] As can be seen, in the above technical solution, when the carbon rod body 12 moves to the first section adjustment block 9 under the drive of the conveyor wheel 6, the carbon rod body 12 is forced to flip under the obstruction of the adjustment block 9, and receives heat from all directions. When the carbon rod body 12 moves to the end of the section adjustment block 9, due to the space design between the tail end and the first section of the two sections adjustment blocks 9, the carbon rod body 12 can smoothly transfer and move to the other section arc-shaped adjustment block 9 set in the opposite direction, and flip in the opposite direction. In this way, the carbon rod body 12 can move and flip from one side to the other side of the furnace body 1 while being conveyed. The carbon rod body 12 can continuously change the heating surface during the entire conveying process, which greatly ensures the uniformity of the carbon rod heating.

[0030] Usage process:

[0031] First, open the furnace door 3 using the handles 4 on both sides of the furnace body 1. Place the carbon rod body 12 horizontally and vertically on the surface of the conveyor wheel 6, with the end of the carbon rod body 12 corresponding to the arc surface of the arc-shaped adjusting block 9. Close the furnace door 3 to ensure the sealing of the furnace body 1 and maintain a stable temperature environment. Start the equipment, and the motor drives the conveyor wheel 6 to rotate, sequentially sending the carbon rod body 12 to the preheating section, sintering section, and cooling section. In the preheating and sintering sections, the controller 2 receives temperature data from three temperature sensors 10 located in different sections. Based on the preset temperature curve and process requirements, it precisely controls the heating power of the resistance wire 7 installed on the inner wall to provide the required heat to the carbon rod body 12. Yes, and at the same time, during the transfer process, the end of the carbon rod body 12 is blocked by the first section of the adjusting block 9, and is flipped under force, so that it is heated in all directions. When it moves to the end of the section of the adjusting block 9, it is smoothly transferred to the other section of the adjusting block 9 in the opposite direction by using the space between the tail end of the two sections of the adjusting block 9 and the first section, and flipped in the opposite direction. The heating surface is constantly changed. In the cooling section, it is connected to the external fan through the air inlet pipe 5 to deliver gas into the furnace, and slowly exchange heat with the carbon rod body 12 after high temperature sintering to achieve slow cooling. The air after heat exchange is discharged from the air outlet pipe 11. Throughout the process, the heat insulation plate 8 effectively blocks the heat conduction in different areas, maintains the temperature gradient, and ensures the smooth progress of each stage of the process.

[0032] Example 2:

[0033] As shown in the figure, this embodiment provides a multi-segment gradient carbon rod high-temperature sintering furnace, including a furnace body 1. The furnace body 1 has a conveyor wheel 6 inside, and a carbon rod body 12 is provided on the surface of the conveyor wheel 6. The shape and position of the carbon rod body 12 correspond to the shape and position of the adjusting block 9. The inner wall top surface of the furnace body 1 is provided with an adjusting block 9. The shape of the adjusting block 9 is arc-shaped, and the position of the adjusting block 9 is adapted to the position of the conveyor wheel 6. The spacing between multiple adjusting blocks 9 is set to ensure that the carbon rod body 12 has enough room to move so that it will not be stuck during the conveying process.

[0034] As can be seen, in the above technical solution, the spacing between the multiple adjustment blocks 9 is determined according to the length and size of the carbon rod body 12 in actual use. It is necessary to ensure that when the carbon rod body 12 is connected between the tail end and the head end of the two adjustment blocks 9, the two ends of the carbon rod body 12 will not be blocked by the two adjustment blocks 9, and that the carbon rod body 12 will not be blocked between the two adjustment blocks 9 during the movement and transmission, so that the carbon rod body 12 has enough space to move.

[0035] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
