Description

Technical Field

[0001] The present application relates to the technical field of sintering furnaces, and more specifically, to an internal airflow buffer system of a sintering furnace. Background Art

[0002] In the field of sintering equipment, taking the sintering furnace as an example, the heat is mainly transferred from the heater to the firing fixture and the four sides of the product by radiation and convection, and the main heating surface on the product is indirectly transferred through the firing fixture.

[0003] In the effective space of the furnace of the sintering furnace, the heat received by products in different places through radiation is definitely inconsistent due to the different distances from the heater and whether there are obstacles. The heat received by convection and conduction will also vary due to the different positions of each place. To ensure the temperature uniformity of each section in the furnace, it is necessary to ensure that the heat received by the products in each place is basically consistent.

[0004] In order to solve the above problems, the present application provides an internal airflow buffer system of a sintering furnace. Summary of the invention

[0007] The auxiliary mechanism includes an insulation layer 1, which is fixedly embedded in the furnace body frame, and insulation layers 2 and 3 are fixedly embedded in both sides of the insulation layer 1 respectively. An air inlet is opened in the insulation layer 2, and a connecting frame is provided on one side of the air inlet. The connecting frame is fixedly embedded in the insulation layer 2 and is connected with the air inlet. The space between the connecting frame and the insulation layer 2 is a primary buffer zone, a buffer cover is fixedly connected to one side of the connecting frame, and the space between the buffer cover and the connecting frame is a secondary buffer zone. A connecting net is fixedly embedded in the buffer cover, and multiple through grooves are opened on one side of the connecting frame and the buffer cover, and the multiple through grooves are evenly distributed with the center line of the connecting frame and the buffer cover as the axis. An air outlet pipe is fixedly embedded in the insulation layer 3, and a driving component is provided on the outside of the air outlet pipe.

[0008] Furthermore, a threaded cover is screwed onto the outer wall of one end of the second insulation layer, and an anti-slip ring is fixedly connected to the bottom of the furnace body frame.

[0009] Through the above technical solution, by providing an anti-slip ring, the friction between the furnace body frame and the ground can be strengthened, thereby making the device more stable when in use.

[0010] Furthermore, a connecting door is provided on the front side of the furnace body frame, and the connecting door is movably connected to the furnace body frame via a hinge.

[0012] Furthermore, the driving component includes a support rod, which is fixedly connected to the bottom inner wall of the furnace frame.

[0013] Furthermore, an electric hydraulic push rod is fixedly embedded on the inner side of the top of the furnace body frame, and the electric hydraulic push rod and the support rod are both embedded in the first insulation layer.

[0014] Through the above technical solution, by setting an electric hydraulic push rod, the height of the upper connecting frame can be easily adjusted at a later stage.

[0015] Furthermore, an upper connecting frame is movably sleeved on the outer side of the bottom end of the electric hydraulic push rod, a lower connecting frame is fixedly connected to the top of the support rod, a turntable is movably embedded on the top of the lower connecting frame, and the top of the turntable is made of anti-slip material.

[0016] Through the above technical solution, since the top of the turntable is made of anti-slip material, the friction between the process sample and the turntable can be enhanced, so that the process sample can be more stable when it rotates slowly.

[0017] Furthermore, a worm wheel is fixedly sleeved on the outer side of the turntable, a worm is meshed with one side of the worm wheel, the rear end of the worm extends to the rear side of the furnace body frame, the rear side of the furnace body frame is fixedly connected to a base, the top of the base is fixedly connected to a motor, the motor output shaft is fixedly connected to the rear end of the worm, and the worm is movably connected to the connection between the insulation layer and the furnace body frame through bearings.

[0018] Through the above technical solution, the worm wheel and the worm gear cooperate with each other, so that the process sample can be slowly rotated at a later stage.

[0019] In summary, this application includes the following beneficial technical effects:

[0020] When it is necessary to introduce process gas to the surface of the process sample, the gas first enters the primary buffer area between the second insulation layer and the connecting frame through the air inlet, and then enters the secondary buffer area between the connecting frame and the buffer cover through multiple through holes inside the connecting frame. Finally, the gas is evenly discharged to the surface of the process sample through multiple through grooves opened inside one side of the buffer cover, and then the gas is discharged through the outlet pipe. The above structure can be optimally used to adjust the intake airflow to ensure that the airflow to the surface of the process sample is uniform. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Example:

[0030] The present application embodiment discloses an internal airflow buffer system of a sintering furnace. Figure 1 , Figure 2and Figure 3 , comprising a furnace frame 1, an auxiliary mechanism is provided inside the furnace frame 1, and the auxiliary mechanism extends to the outside of the furnace frame 1;

[0031] The auxiliary mechanism includes an insulation layer 2, which is fixedly embedded in the furnace body frame 1, and insulation layers 2 3 and 3 4 are fixedly embedded in both sides of the insulation layer 2, respectively. An air inlet 5 is provided in the insulation layer 2 3, and a connecting frame 6 is provided on one side of the air inlet 5. The connecting frame 6 is fixedly embedded in the insulation layer 2 3 and communicated with the air inlet 5. The space between the connecting frame 6 and the insulation layer 2 3 is a primary buffer zone 7, a buffer cover 8 is fixedly connected to one side of the connecting frame 6, and the space between the buffer cover 8 and the connecting frame 6 is a secondary buffer zone 9. A connecting net 10 is fixedly embedded in the buffer cover 8, and a plurality of through grooves are provided on one side of the connecting frame 6 and the buffer cover 8, and the plurality of through grooves are evenly distributed with the center line of the connecting frame 6 and the buffer cover 8 as the axis, and an air outlet pipe 11 is fixedly embedded in the insulation layer 3 4;

[0032] See also Figure 1 and Figure 2 A driving component is provided on the outside of the air outlet pipe 11, a threaded cover is screwed on the outer wall of one end of the insulation layer 2 3, an anti-skid ring is fixedly connected to the bottom of the furnace body frame 1, a connecting door is provided on the front side of the furnace body frame 1, and the connecting door and the furnace body frame 1 are movably connected through a hinge. By setting the anti-skid ring, the friction between the furnace body frame 1 and the ground can be strengthened, so that the device can be more stable when in use. At the same time, the connection door and the hinge cooperate with each other, which can facilitate the removal or placement of process samples in the later stage;

[0033] See also Figure 2 The driving component includes a support rod 12, the support rod 12 is fixedly connected to the bottom inner wall of the furnace body frame 1, and an electric hydraulic push rod 13 is fixedly embedded on the inner side of the top of the furnace body frame 1. The electric hydraulic push rod 13 and the support rod 12 are both embedded in the insulation layer 2. By setting the electric hydraulic push rod 13, the height of the upper connecting frame 14 can be adjusted later;

[0034] See also Figure 1 and Figure 2The outer side of the bottom end of the electric hydraulic push rod 13 is movably sleeved with an upper connecting frame 14, the top of the support rod 12 is fixedly connected to a lower connecting frame 15, and a turntable 16 is movably embedded on the top of the lower connecting frame 15. The top of the turntable 16 is made of anti-slip material, and a worm gear 17 is fixedly sleeved on the outer side of the turntable 16. A worm 18 is meshed on one side of the worm gear 17. The rear end of the worm 18 extends to the rear side of the furnace body frame 1, and a base is fixedly connected to the rear side of the furnace body frame 1. A motor 19 is fixedly connected to the top of the base, and the output shaft of the motor 19 is fixedly connected to the rear end of the worm 18. The worm 18 is movably connected to the insulation layer 2 and the furnace body frame 1 through bearings. Because the top of the turntable 16 is made of anti-slip material, the friction between the process sample and the turntable 16 can be strengthened, so that the process sample can be more stable when it is slowly rotated. At the same time, through the cooperation between the worm gear 17 and the worm 18, it is convenient to slowly rotate the process sample in the later stage.

[0035] The implementation principle of this embodiment is as follows: when it is necessary to introduce process gas into the surface of the process sample, the connecting door can be rotated and opened by the hinge first, and then the process sample can be placed on the top of the turntable 16. After placement, the electric hydraulic push rod 13 is started again, so that the telescopic end of the electric hydraulic push rod 13 is stretched to drive the upper connecting frame 14 to move downward. When the upper connecting frame 14 contacts the process sample, the motor 19 can be started, and the worm 18 is driven to rotate by the output shaft of the motor 19. The worm 18 is meshed with the worm wheel 17 to make the turntable 16 rotate slowly. When the turntable 16 rotates, the process sample will rotate accordingly. At the same time, the gas enters the primary buffer zone 7 between the insulation layer 2 3 and the connecting frame 6 through the air inlet 5, and then enters the secondary buffer zone 9 between the connecting frame 6 and the buffer cover 8 through the multiple through holes inside the connecting frame 6. Finally, the gas is evenly discharged to the surface of the process sample through the multiple through grooves opened inside one side of the buffer cover 8, and then the gas is discharged through the outlet pipe 11. Through the above structure, it can be optimally used to adjust the intake airflow to ensure that the airflow to the surface of the process sample is uniform.

[0036] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
