Description

Technical Field

[0001] This utility model relates to the field of sintering furnace technology, and more specifically, to a sintering furnace atmosphere environment conditioning device. Background Technology

[0002] An atmosphere sintering furnace is a process testing instrument used in the fields of chemistry, materials science, electronics and communication technology. The working principle of an atmosphere sintering furnace mainly involves the combined effects of high temperature, high pressure and a specific atmosphere on materials. This equipment generates high temperature through heating elements and creates a specific atmosphere in the furnace to achieve the sintering treatment of materials. In an atmosphere sintering furnace, "atmosphere" refers to a specific protective gas or vacuum environment that is introduced into the furnace to replace natural air during the sintering process.

[0003] Existing atmosphere sintering furnaces control the composition and flow of the atmosphere within the furnace through an atmosphere control structure composed of mechanical valves, electronic leakage valves, and other devices to meet the atmosphere requirements of different processes. For example, Chinese utility model patent CN201954947U discloses a sintering atmosphere conditioning system for an industrial-grade microwave high-temperature roller conveyor continuous sintering kiln. This system connects to a regulating valve via multiple air inlets and outlets, using different types of protective gases (such as dry air, nitrogen, and argon) to regulate the air inlet and outlet volumes. Combined with an inlet flow meter and an outlet temperature gauge, precise control of the sintering atmosphere is achieved. While existing technical solutions can achieve atmosphere conditioning, using the same pipeline to introduce different atmospheres makes it difficult to maintain the purity of the atmosphere environment. The limited atmosphere diffusion rate can easily cause the sintered parts to come into contact with different atmospheres simultaneously, resulting in poor atmosphere switching efficiency and effectiveness, which can negatively impact product quality and reduces practicality. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a sintering furnace atmosphere environment adjustment device, so as to realize the switching of atmosphere environment by adjusting the position of the placement structure, and effectively prevent the sintered parts from contacting different atmospheres at the same time while ensuring the efficiency of atmosphere environment switching, thereby improving product production quality and device practicality.

[0005] To achieve the above objectives, this utility model provides a sintering furnace atmosphere environment conditioning device, installed inside the furnace body, including a partition plate horizontally installed on the inside of the furnace body, an adjustment component fixedly installed on the furnace body, a mounting structure located inside the furnace body and installed on top of the adjustment component, and two sets of air inlet components and air outlet components installed on the furnace body. The partition plate has a vertically open communicating hole, and the partition plate is adapted to evenly divide the inside of the furnace body into an upper inner cavity and a lower inner cavity. The two sets of air inlet components are respectively located on one side of the length direction of the upper inner cavity and the lower inner cavity, and the two sets of air outlet components are respectively located on the other side of the length direction of the upper inner cavity and the lower inner cavity. The mounting structure includes a lower mounting plate installed on top of the adjustment assembly, an upper mounting plate located directly above the lower mounting plate, and two vertically parallel baffles installed between the lower mounting plate and the upper mounting plate. Both the lower mounting plate and the upper mounting plate are circular and their dimensions are adapted to the inner diameter of the connecting hole. The adjustment assembly is adapted to drive the mounting structure to rise, fall, and rotate.

[0006] Furthermore, the adjustment assembly includes an electric push rod, a lifting seat, a connecting block, and a rotary motor. The electric push rod is fixedly installed at the bottom of the furnace body and extends into the inside of the furnace body. The lifting seat, the connecting block, and the rotary motor are all located inside the furnace body. The lifting seat is fixedly installed at the top of the electric push rod, the rotary motor is fixedly installed at the bottom of the lifting seat, and the connecting block is fixedly installed at the output end of the rotary motor and located inside the lifting seat. The upper surface of the connecting block is fixedly connected to the lower mounting plate.

[0007] Furthermore, the connecting block is inverted T-shaped, and the top of the lifting seat has a rotating groove that slides and adapts to the connecting block.

[0008] Furthermore, the bottom wall of the furnace body is provided with a concave groove for accommodating the lifting seat, the connecting block and the rotary motor, and the inner diameter of the concave groove is adapted to the size of the lower mounting plate.

[0009] Furthermore, the inner wall of the furnace body is provided with a first arc-shaped groove that is slidably adapted to the lower mounting plate or the upper mounting plate.

[0010] Furthermore, the distance between the lower mounting plate and the upper mounting plate is consistent with the height of the upper inner cavity or the lower inner cavity, and the length of the baffle and the distance between the two baffles are the same as the width of the upper inner cavity or the lower inner cavity.

[0011] Furthermore, the air intake component includes an air intake pipe installed on one side of the furnace body along its length and a flow equalization plate installed vertically inside the furnace body and corresponding to the position of the air intake pipe. The outer wall size of the flow equalization plate is adapted to the inner wall size of the upper inner cavity or the lower inner cavity.

[0012] Furthermore, the gas outlet component includes a gas outlet pipe installed on the side of the furnace body away from the gas inlet pipe along the length direction of the furnace body and a gas collecting head installed inside the furnace body. The outer wall size of the gas collecting head is adapted to the inner wall size of the upper inner cavity or the lower inner cavity.

[0013] Furthermore, a furnace door is provided on the open side of the furnace body, and a second arc-shaped groove is provided on the furnace door to slide and adapt to the lower mounting plate or the upper mounting plate.

[0014] Furthermore, four support columns are installed on the bottom surface of the furnace body, and the length of the support columns is greater than the length of the electric push rod.

The sintering furnace atmosphere environment adjustment device of this utility model is provided with an upper inner cavity and a lower inner cavity. The upper inner cavity and the lower inner cavity can be filled with different atmospheres, so that the atmosphere environment can be quickly switched by adjusting the position of the sintering sample when switching atmospheres. Moreover, by adjusting the placement structure through the adjustment component, the airflow interaction between the upper inner cavity and the lower inner cavity can be isolated during the position adjustment of the sintering sample, thereby avoiding the sintering sample from contacting two or more atmospheres at the same time, effectively improving the switching efficiency and switching quality of the sintering atmosphere, and enhancing the practicality of the device.

[0016] 2. The sintering furnace atmosphere conditioning device of this utility model adjusts the angle of the baffle relative to the length direction of the upper and lower inner cavities by rotating the placement structure. When the baffle is parallel to the length direction of the upper and lower inner cavities, the gas can pass through the placement structure so that the sintered part can fully contact the atmosphere. When the baffle is perpendicular to the length direction of the upper and lower inner cavities, the baffle can block the gas flow and prevent the atmosphere from contacting the sintered part, so as to prevent gas interaction during the adjustment of the placement structure position.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can also refer to the internal connection of two components; and they can refer to a wireless connection or a wired connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] Please see Figure 1-3 As shown, this utility model embodiment provides a sintering furnace atmosphere environment adjustment device, which is installed inside the furnace body 1. It includes a partition 3, an adjustment component 5, a mounting structure 4, an air inlet component 6, and an air outlet component 7. The partition 3 is horizontally installed inside the furnace body 1. The adjustment component 5 is fixedly installed on the furnace body 1. The mounting structure 4 is located inside the furnace body 1 and installed on top of the adjustment component 5. Two sets of air inlet components 6 and two sets of air outlet components 7 are installed on the furnace body 1. A vertical connecting hole 31 is provided on the partition 3. The partition 3 is suitable for uniformly dividing the inner side of the furnace body 1 into an upper inner cavity 14 and a lower inner cavity 15. The two sets of air inlet components 6 are respectively located on one side of the upper inner cavity 14 and the lower inner cavity 15 along the length direction. The two sets of air outlet components 7 are respectively located on the other side of the upper inner cavity 14 and the lower inner cavity 15 along the length direction. The mounting structure 4 includes a lower mounting plate 41, an upper mounting plate 43, and baffles 42. The lower mounting plate 41 is mounted on top of the adjusting assembly 5, and the upper mounting plate 43 is located directly above the lower mounting plate 41. The two baffles 42 are vertically parallel between the lower mounting plate 41 and the upper mounting plate 43. Both the lower mounting plate 41 and the upper mounting plate 43 are circular and their dimensions are adapted to the inner diameter of the connecting hole 31. The adjusting assembly 5 is suitable for driving the mounting structure 4 to rise, fall, and rotate.

[0022] Specifically, when the placement structure 4 is located in the upper inner cavity 14 or the lower inner cavity 15 and the baffle 42 in the placement structure 4 is parallel to the length direction of the upper inner cavity 14 or the lower inner cavity 15, the atmosphere can be filled and flowed by operating the corresponding air inlet component 6 and air outlet component 7. Different sintering stages require different atmosphere types and atmosphere flow rates. When it is necessary to switch the atmosphere, the placement structure 4 can be rotated so that the baffle 42 in the placement structure 4 is perpendicular to the length direction of the upper inner cavity 14 or the lower inner cavity 15. At this time, the baffle 42 in the placement structure 4 can prevent the original atmosphere from contacting the sintering sample. When the adjustment component 5 pushes the sample into another inner cavity, the placement structure 4 can be rotated ninety degrees again to place the sintering sample in the flow path of another atmosphere type, thereby achieving efficient atmosphere adjustment and improving sintering quality and production efficiency.

[0023] As a preferred embodiment of the above solution, the upper surface of the lower mounting plate 41 in this application may be provided with a grid-like groove or small protrusions to reduce the contact between the sintered sample and the lower mounting plate 41, while allowing gas to flow into the gap between the sintered sample and the lower mounting plate 41, thereby maintaining a good atmosphere protection effect on the lower surface of the sintered sample.

[0024] Please see Figure 2 As shown, the adjustment assembly 5 includes an electric push rod 51, a lifting seat 52, a connecting block 53, and a rotary motor 54. The electric push rod 51 is fixedly installed at the bottom of the furnace body 1 and extends to the inside of the furnace body 1. The lifting seat 52, the connecting block 53, and the rotary motor 54 are all located inside the furnace body 1. The lifting seat 52 is fixedly installed at the top of the electric push rod 51, the rotary motor 54 is fixedly installed at the bottom of the lifting seat 52, and the connecting block 53 is fixedly installed at the output end of the rotary motor 54 and located inside the lifting seat 52. The upper surface of the connecting block 53 is fixedly connected to the lower mounting plate 41. This allows the lifting seat 52 to move the connecting block 53 and the lower mounting plate 41 up and down by the operation of the electric push rod 51. The rotary motor 54 can also drive the connecting block 53 and the lower mounting plate 41 to rotate, thereby adjusting the height and rotation angle of the mounting structure 4.

[0025] Please see Figure 2 As shown, the connecting block 53 is inverted T-shaped, and the top of the lifting seat 52 is provided with a rotating groove that is adapted to slide with the connecting block 53; the rotating groove can prevent the connecting block 53 from disengaging from the lifting seat 52 without affecting the rotation of the connecting block 53.

[0026] Please see Figure 2 As shown, the bottom wall of the furnace body 1 is provided with a concave groove 12 for accommodating the lifting seat 52, the connecting block 53 and the rotary motor 54, and the inner diameter of the concave groove 12 is adapted to the size of the lower mounting plate 41; this facilitates the use of the concave groove 12 to accommodate the lifting seat 52, the connecting block 53 and the rotary motor 54 during the downward movement of the lower mounting plate 41, effectively reducing collision damage.

[0027] Please see Figure 1-3 As shown, the inner wall of the furnace body 1 is provided with a first arc groove 13 that is slidably adapted to the lower mounting plate 41 or the upper mounting plate 43; the first arc groove 13 provided during the lifting and rotation of the mounting structure 4 can make the lower mounting plate 41 and the upper mounting plate 43 move smoothly.

[0028] Please see Figure 1-3 As shown, the distance between the lower mounting plate 41 and the upper mounting plate 43 is consistent with the height of the upper inner cavity 14 or the lower inner cavity 15, and the length of the baffle 42 and the distance between the two baffles 42 are the same as the width of the upper inner cavity 14 or the lower inner cavity 15. By limiting the above dimensions, when the structure 4 is placed in the upper inner cavity 14 or the lower inner cavity 15, the lower mounting plate 41 or the upper mounting plate 43 can close the connecting hole 31, effectively preventing the atmosphere in the current inner cavity from moving to the other inner cavity.

[0029] Please see Figure 1-3 As shown, the air intake component 6 includes an air intake pipe 61 installed on one side of the furnace body 1 along its length and a flow equalization plate 62 installed vertically inside the furnace body 1 and corresponding to the position of the air intake pipe 61. The outer wall size of the flow equalization plate 62 is adapted to the inner wall size of the upper inner cavity 14 or the lower inner cavity 15. This facilitates the filling of the upper inner cavity 14 or the lower inner cavity 15 with gas by installing a gas supply device connected to the air intake pipe 61 and adjusting the flow rate. The flow equalization plate 62 also enables the gas to flow evenly and make uniform contact with the surface of the sintered sample in the placement structure 4.

[0030] Please see Figure 1-3 As shown, the gas outlet component 7 includes a gas outlet pipe 71 installed on the side of the furnace body 1 away from the gas inlet pipe 61 along the length direction, and a gas collecting head 72 installed inside the furnace body 1. The outer wall size of the gas collecting head 72 is adapted to the inner wall size of the upper inner cavity 14 or the lower inner cavity 15. This facilitates the exhaust of the atmosphere from the upper inner cavity 14 or the lower inner cavity 15 by installing an exhaust device connected to the gas outlet pipe 71, thereby facilitating the maintenance of good atmosphere flow effect between the gas outlet pipe 71 and the gas collecting head 72.

[0031] Please see Figure 1 and Figure 3 As shown, a furnace door 2 is provided on the open side of the furnace body 1. A second arc groove 21 is provided on the furnace door 2 to slide and adapt to the lower mounting plate 41 or the upper mounting plate 43. When the furnace door 2 is closed, the second arc groove 21 can make the lower mounting plate 41 and the upper mounting plate 43 move smoothly in lifting and rotating motion.

[0032] As a further description of the above scheme, if the baffle 42 is perpendicular to the length direction of the upper inner cavity 14 or the lower inner cavity 15, the lower mounting plate 41 and the upper mounting plate 43 can maintain the relative closure of the placement structure 4 by means of the fitting action of the first arc groove 13 and the second arc groove 21, thereby effectively preventing gas from flowing to the inside of the placement structure 4, and thus facilitating the prevention of the atmosphere in the upper inner cavity 14 or the lower inner cavity 15 from flowing to the other inner cavity during the lifting and lowering process of the placement structure 4.

[0033] Please see Figure 1-2 As shown, four support columns 11 are installed on the bottom surface of the furnace body 1, and the length of the support columns 11 is greater than the length of the electric push rod 51; the support columns 11 can prevent the electric push rod 51 from directly contacting the ground.

[0034] The working process of the above-mentioned sintering furnace atmosphere conditioning device is as follows: When using this sintering furnace atmosphere conditioning device, it is first necessary to install gas supply equipment connected to the two gas inlet pipes 61 to facilitate the filling of the upper inner cavity 14 or the lower inner cavity 15 with atmosphere. At the same time, it is necessary to install gas extraction equipment connected to the two gas outlet pipes 71 to facilitate the exhaust of the atmosphere from the upper inner cavity 14 or the lower inner cavity 15, so as to maintain the airflow in the upper inner cavity 14 or the lower inner cavity 15 during gas filling. The upper inner cavity 14 and the lower inner cavity 15 are filled with different atmospheres, thereby adjusting the atmosphere environment by changing the position of the placement structure 4.

[0035] When sintering the sintered parts, the sample to be sintered needs to be placed on the lower mounting plate 41 of the mounting structure 4. At the same time, the furnace door 2 is closed and the position of the mounting structure 4 is adjusted so that it is in the upper inner cavity 14 or the lower inner cavity 15, so as to cooperate with the heating function of the furnace body 1 to achieve the sintering effect. Then, when the baffle 42 in the mounting structure 4 is parallel to the length direction of the upper inner cavity 14 or the lower inner cavity 15, the gas supply equipment is used to fill the upper inner cavity 14 or the lower inner cavity 15 corresponding to the mounting structure 4 with atmosphere, so that the atmosphere flows evenly to the sintering sample under the action of the flow equalization plate 62, thereby achieving the atmosphere sintering effect. Furthermore, when the sintered sample needs to change its atmosphere to enter another stage, the rotation of the placement structure 4 can be controlled by the rotary motor 54 in the adjustment component 5. When the baffle 42 in the placement structure 4 is perpendicular to the length direction of the upper inner cavity 14 or the lower inner cavity 15, it can block the flow of atmosphere and prevent the atmosphere in the current inner cavity from contacting the sintered sample. Then, the electric push rod 51 can be operated to move the placement structure 4 up or down to another inner cavity. At this time, the placement structure 4 can be rotated again to make it parallel to the length direction of the upper inner cavity 14 or the lower inner cavity 15, so that the sintered sample is in another atmosphere, thereby realizing the switching of the atmosphere.

[0036] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this invention.
