Description

Technical Field

[0001] This utility model relates to the field of sintering furnace technology, and in particular to a molten block experimental sintering furnace. Background Technology

[0002] In the field of frit experimental research and production, the frit experimental sintering furnace is the core equipment for realizing high-temperature melting of solid raw materials and preparing uniform frit. It usually uses the furnace body as the main heating body, with a crucible inside to support the raw materials. At the same time, the discharge state of the crucible is controlled by the stopper rod to ensure the controllability and stability of the frit sintering process. It is widely used in experimental frit preparation scenarios in the fields of glass, ceramics, and new materials.

[0003] However, existing fused ingot experimental sintering furnaces have significant drawbacks in the feeding process: because the stopper needs to be moved during discharge to control the material flow, the stopper needs to partially protrude outside the crucible, making it difficult for the traditional feeding structure to be directly moved and precisely aligned with the crucible; moreover, the traditional feeding method cannot evenly guide the material from all sides into the space between the crucible and the stopper, and the material is prone to accumulate on the top of the stopper or spill outside the crucible, which not only wastes the material but may also contaminate the equipment and affect the subsequent sintering effect. Therefore, we propose the fused ingot experimental sintering furnace to solve this problem. Utility Model Content

[0017] 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.

[0018] Please see Figure 1 - Figure 5 The embodiments provided by this utility model are as follows: The experimental sintering furnace for fused materials includes a furnace body 1, a crucible 2 is disposed inside the furnace body 1, and a stopper rod 3 is disposed inside the crucible 2. The furnace body 1, crucible 2 and stopper rod 3 are existing technologies. For reference, the furnace body, stopper rod and crucible in a high-temperature fused material furnace disclosed in prior art announcement number CN220892926U can be used. The furnace body is a high-temperature fused material furnace. The furnace body melts materials through the crucible and its internal heating mechanism. The stopper rod is used to seal the bottom discharge port of the crucible. A vertical plate 27 is installed on the side of the furnace body 1 through a moving mechanism. Three positioning rods 12 are fixedly installed on the side of the vertical plate 27. Positioning blocks 13 are slidably sleeved on the positioning rods 12 on both sides. The same U-shaped plate 6 is fixedly installed on the side of the two positioning blocks 13 that are close to each other. One end of the positioning rod 12 located in the middle passes through the side of the U-shaped plate 6 and is rotatably mounted with a push rod 11. The bottom end of the push rod 11 is rotatably mounted with a feeding column 4. The feeding column 4 is connected to the inner walls of both sides of the U-shaped plate 6 through two elastic mechanisms. Both sides of the U-shaped plate 6 are fixedly equipped with baffles 7, and the top of the furnace body 1 is fixedly equipped with two baffles 5, the two baffles 5 and the two baffles 7 are positioned corresponding to each other.

[0019] like Figure 2 As shown, the moving mechanism includes two guide rods 8 fixedly installed on the side of the furnace body 1. A mounting plate 15 is fixedly installed at the end of each guide rod 8 away from the furnace body 1. A motor 14 is fixedly installed on the side of the mounting plate 15. The output shaft of the motor 14 passes through the side of the mounting plate 15 and is fixedly installed with a screw 16. The end of the screw 16 away from the mounting plate 15 is rotatably connected to the side of the furnace body 1. Two sliding holes and one threaded hole are provided on the side of the vertical plate 27. The two guide rods 8 are slidably installed in the two sliding holes, and the screw 16 is threadedly installed in the threaded hole. When the motor 14 is started, the output shaft of the motor 14 rotates, causing the screw 16 to rotate. The rotation of the screw 16 causes the vertical plate 27 to move. The movement of the vertical plate 27 causes the positioning rod 12 and the U-shaped plate 6 to move. The movement of the U-shaped plate 6 causes the feeding column 4 and the two stops 7 to move.

[0020] like Figure 2As shown, the elastic mechanism includes a reset rod 17, a reset block 19 is slidably sleeved on the reset rod 17, the side of the reset block 19 is fixedly installed on the side of the feed column 4, a groove is opened on one side of the U-shaped plate 6, the top and bottom ends of the reset rod 17 are fixedly installed on the top and bottom inner walls of the groove, respectively, and a reset spring 18 is sleeved on the reset rod 17, the two ends of the reset spring 18 are fixedly installed on the inner bottom wall of the groove and the bottom of the reset block 19, respectively. Initially, the reset spring 18 is in a compressed state, and the top of the reset block 19 is in contact with the inner top wall of the groove, so that the reset block 19 will not move. When the material column 4 moves directly above the stopper rod 3, if the vertical plate 27 continues to move, the position of the U-shaped plate 6 will not change, so that the positioning rod 12 can slide relative to the U-shaped plate 6, thereby causing the push rod 11 to rotate. The rotation of the push rod 11 causes the material column 4 to move downward, and the two reset springs 18 continue to be compressed, so that the bottom of the material column 4 contacts the top of the crucible 2, so that the bottom opening of the conical groove 21 corresponds to the top opening of the crucible 2, and at the same time, the stopper rod 3 enters the conical sleeve 20.

[0021] like Figure 4 As shown, the top of the feeding column 4 is provided with an upper conical groove 24, the bottom of the feeding column 4 is provided with a conical groove 21, the top inner wall of the conical groove 21 is provided with a lower conical groove 22, the inner walls of the lower conical groove 22 and the upper conical groove 24 are provided with cylindrical holes 23, the inner wall of the conical groove 21 is fixedly installed with two connecting blocks 26, the bottom of the conical block 25 is fixedly installed with a conical sleeve 20, and the top of the conical block 25 corresponds to the cylindrical hole 23. The distance between the side of the conical block 25 and the inner wall of the lower conical groove 22 is equal to the distance between the side of the conical sleeve 20 and the inner wall of the conical groove 21. The size of the upper opening of the lower conical groove 22 is smaller than the size of the lower opening of the lower conical groove 22. The size of the upper opening of the conical groove 21 is larger than the size of the lower opening of the lower conical groove 22. The size of the upper opening of the upper conical groove 24 is larger than the size of the lower opening of the upper conical groove 24. The bottom of the feed column 4 is adapted to the crucible 2. The conical sleeve 20 is adapted to the stopper rod 3. The material is placed into the upper conical groove 24. When the material enters the upper conical groove 24, it will fall into the cylindrical hole 23. After passing through the cylindrical hole 23, it will fall to the top of the conical block 25. The top of the conical block 25 will divert the material and distribute it evenly in the space between the lower conical groove 22 and the conical block 25. Then, it will pass through the space between the conical sleeve 20 and the conical groove 21 and enter the space between the crucible 2 and the stopper rod 3. Finally, it will fall into the crucible 2, thus achieving uniform material distribution and preventing it from falling on the top of the stopper rod 3 or outside the crucible 2.

[0022] like Figure 1As shown, the horizontal distance between the stop rod 5 and the stop block 7 along the guide rod 8 on their adjacent sides is equal to the horizontal distance between the central axis of the stopper rod 3 and the central axis of the feed column 4; the plane containing the central axis of the stopper rod 3 and the central axis of the feed column 4 is perpendicular to the side of the vertical plate 27 away from the mounting plate 15. The advantage of this arrangement is that when the feed column 4 moves directly above the stopper rod 3, the two stop blocks 7 contact the two stop rods 5 respectively.

[0023] like Figure 1 As shown, a support frame 10 is fixedly installed at the bottom of the furnace body 1, and a control box 9 is installed on one side of the support frame 10. The support frame 10 is used for support, and the control box 9 is used for control.

[0024] Working principle: When in use, if material needs to be discharged, the motor 14 is started. The output shaft of the motor 14 rotates, which drives the screw 16 to rotate. The rotation of the screw 16 drives the vertical plate 27 to move. The movement of the vertical plate 27 drives the positioning rod 12 and the U-shaped plate 6 to move. The movement of the U-shaped plate 6 drives the discharge column 4 and the two stop blocks 7 to move. When the discharge column 4 moves directly above the stop bar 3, the two stop blocks 7 contact the two stop rods 5 respectively. If the vertical plate 27 continues to move, the position of the U-shaped plate 6 will not change, so that the positioning rod 12 can slide relative to the U-shaped plate 6, thereby causing the push rod 11 to rotate. The rotation of the push rod 11 causes the feed column 4 to move downward, and the two return springs 18 continue to be compressed, so that the bottom of the feed column 4 contacts the top of the crucible 2, and the bottom opening of the conical groove 21 corresponds to the top opening of the crucible 2. At the same time, the stopper rod 3 enters the conical sleeve 20. Then, the material is placed into the upper conical groove 24. When the material enters the upper conical groove 24, it will fall into the cylindrical hole 23. After passing through the cylindrical hole 23, it will fall to the top of the conical block 25. The top of the conical block 25 will divert the material and distribute it evenly in the space between the lower conical groove 22 and the conical block 25. Then, it will pass through the space between the conical sleeve 20 and the conical groove 21 and enter the space between the crucible 2 and the stopper rod 3. Finally, it will fall into the crucible 2, thus achieving uniform material distribution and preventing it from falling on the top of the stopper rod 3 or outside the crucible 2.

[0025] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
