Description

Technical Field

[0001] The utility model relates to the technical field of alloy smelting, in particular to a high-strength alloy sintering tunnel kiln. Background Art

[0002] As an advanced material widely used in the steel industry at home and abroad, the production process and supporting equipment of high-strength alloys have undergone rapid technological innovation and progress. Tunnel kilns play a vital role in the sintering of high-strength alloys. This equipment not only plays a core role in the high-temperature roasting process of ceramic products, but also shows significant practical value in abrasive manufacturing and metallurgy. Tunnel kilns, as a continuous firing equipment representing modern thermal technology, are adapting to the ever-changing needs of industrial production.

[0003] Existing tunnel kilns are generally equipped with gates at the feeding pipe ports. However, when the sintering sagger is fed into the tunnel kiln, the opening of the gate will inevitably cause a small amount of gas to enter the tunnel kiln, which will have an adverse effect on the sintering process and thus affect the quality and stability of the product. Although some tunnel kilns are designed with a double gate structure to effectively reduce the amount of gas infiltration, the devices that drive the sintering sagger operate independently and lack a linkage mechanism, which not only complicates the operation process but also leads to low production efficiency.

[0004] Therefore, the utility model provides a high-strength alloy sintering tunnel kiln to solve the problems raised in the above background technology. Utility Model Content

Then, the hydraulic cylinder in the first feeding pipe is started to drive the connecting blocks on both sides of the feeding door to slide along the outside of the fixed column to close the feeding door. As the connecting block descends, pressure is applied to the output end of the first cylinder to shrink it, so that the gas in the first cylinder flows into the second cylinder through the gas pipe in the feeding pipe, and drives the second cylinder to extend. As the second cylinder extends, the discharge plate slides at the lower end inside the feeding pipe. When the feeding door is completely closed, the sintering sagger will accurately reach the predetermined position, thereby ensuring the accuracy of the operation and improving the efficiency of the sintering of the high-strength alloy.

[0024] 2. The utility model proposes a high-strength alloy sintering tunnel kiln. When the sintering sagger completely enters the second feeding tube and the feeding door of the first feeding tube is tightly closed, the motor inside the second feeding tube is started to drive the first screw rod to start rotating. As the first screw rod rotates, the first slider will slide smoothly on the outside of the first fixed rod and the first screw rod, thereby driving the gate connected to it to follow the movement. At the same time, the first bevel gear connected to the lower end of the first screw rod will drive the second bevel gear meshing with it to rotate synchronously, thereby driving the lower end of the push plate to slide smoothly on the outside of the second screw rod and the second connecting rod, and finally the push plate applies just the right thrust to the high-strength alloy sagger, ensuring that it can smoothly enter the tunnel kiln, reducing the impact on sintering, and achieving efficient sintering operations.

When the connecting block 203 descends, pressure is applied to the output end of the first cylinder 204 to cause it to contract. At this time, the gas inside the first cylinder 204 is transported to the second cylinder 207 through the gas pipe 208 inside the first feeding pipe 1, thereby driving the second cylinder 207 to perform the extension action. As the second cylinder 207 extends, the discharge plate 206 connected to its output end slides along the guide rail at the lower end inside the first feeding pipe 1. When the feeding door 202 is completely closed, the second cylinder 207 will also push the discharge plate 206 to the final predetermined position.

[0038] When the sintering sagger loaded with high-strength alloy reaches the inside of the second feeding tube 4, and the feeding door 202 inside the first feeding tube 1 is completely closed, the pushing mechanism 6 inside the second feeding tube 4 is started, the motor 601 runs and drives the first screw rod 604 at its output end to rotate, and the rotation of the first screw rod 604 drives the first sliders 603 on both sides of the gate 608 to slide on the first fixed rod 609 and the outside of the first screw rod 604. As the first screw rod 604 continues to rotate, the first bevel gear 605 fixed at its lower end rotates accordingly. The first bevel gear 605 is meshed with the second bevel gear 606, so that the first bevel gear 605 drives the second bevel gear 606 to rotate, and the rotation of the second screw rod 607 drives the lower end of the push plate 610 to slide outside the second screw rod 607 and the second connecting rod 611, and finally the push plate 610 applies a thrust to the high-strength alloy sagger at the top of the discharge plate 206, so that it can smoothly enter the interior of the tunnel kiln body 5 and start the sintering operation, thereby realizing the automatic operation of the high-strength alloy sintering process, which not only reduces the impact on sintering, but also improves the sintering efficiency.

When the two connecting blocks 203 are descending, the output end of the first cylinder 204 is squeezed to make it contract, and the gas inside it flows into the second cylinder 207 through the gas pipe 208 inside the first feeding pipe 1, thereby driving the second cylinder 207 to extend, so as to drive the discharge plate 206 connected to its output end to slide at the lower end inside the first feeding pipe 1. When the feeding door 202 is completely closed, the second cylinder 207 will move the discharge plate 206 to the final position, thereby driving the sagger to move, and then the exhaust fan 7 at the upper end of the first feeding pipe 1 is started to make the first feeding pipe 1 and The gas inside the second feeding pipe 4 is discharged, and the filtering device 8 can filter the internal gas. When the gas inside the first feeding pipe 1 and the second feeding pipe 4 is less, the pushing mechanism 6 inside the second feeding pipe 4 is started, and the first screw rod 604 at its output end is driven to rotate by operating the motor 601, thereby driving the first sliders 603 on both sides of the gate 608 to slide outside the first fixed rod 609 and the first screw rod 604. When the first screw rod 604 rotates, it will drive the first bevel gear 605 fixed at its lower end to rotate, so that the first bevel gear 605 rotates to drive the second bevel gear 606 meshing with it to rotate, and then the second screw rod 607 rotates, thereby driving the lower end of the push plate 610 to slide outside the second screw rod 607 and the second connecting rod 611, and the push plate 610 pushes the high-strength alloy sagger at the upper end of the discharge plate 206, so that it enters the tunnel kiln furnace body 5 for sintering operation, thereby improving the sintering efficiency and quality.
