The furnace chamber is fixedly provided at the bottom of the trolley furnace, and rollers and roller grooves of the trolley furnace are fixedly connected to the bottom of the furnace chamber. The tractor is fixedly provided at the bottom of the trolley furnace. Heat insulation front plates are provided on the left and right sides of the trolley furnace respectively. The heat insulation front plates are fixedly connected to aluminum material one, tempered glass, insulated glass, high-temperature glass, and aluminum material two. Side wall rollers are fixedly connected to the outer walls of the left and right sides of the trolley furnace. The two side wall rollers are the same size and shape and move at a uniform speed. Support columns are fixedly provided on both sides of the trolley furnace. Side sliding grooves are fixedly provided on the inner and outer walls of the support columns. The side sliding grooves on both sides are in a parallel state. The top of the heat insulation front plate is hinged to the right side of the front plate. Screw holes and screws are fixedly provided on the left side of the heat insulation front plate for easy disassembly, maintenance and cleaning of the heat insulation front plate. The middle position of the insulated glass is set with vacuum, and two pieces of high-temperature glass are fixedly provided on the left and right sides.

[0003] In actual use, heat insulation plates are installed on both sides of the bogie furnace to insulate the high temperature inside the bogie furnace. However, when the tractor is pushed into the heating chamber, there may be gaps between the tractor and the surrounding guard plate. At the same time, the side of the tractor that is pushed in may not be sealed tightly with the guard plate, causing the heat generated inside the chamber to leak out through the gaps, reducing the working efficiency of the bogie furnace and increasing the cost of the enterprise. Utility Model Content

[0004] The purpose of this invention is to provide a bogie furnace insulation device with good sealing performance, automatic suction, and effective improvement of the overall heat insulation of the bogie furnace.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] The furnace includes a furnace body, a tractor unit is slidably connected inside the furnace body, a baffle is fixed at the end of the tractor unit away from the furnace body, the baffle is provided with a groove, a first sealing element is elastically connected inside the groove, a heat insulation plate is fixed inside the furnace body, the end of the heat insulation plate extends out of the furnace body away from the furnace body, and the end of the heat insulation plate extending out of the furnace body abuts against the first sealing element, a second sealing element is provided on both sides of the first sealing element, the second sealing element includes a plug rod fixed on the baffle, a round head is fixed at the end of the plug rod away from the baffle, and a plug hole is provided on the side of the furnace body corresponding to the position of the round head.

[0007] Furthermore, the first sealing element includes a spring fixed inside the groove, and there are several springs evenly distributed inside the groove, with a heat insulation cotton plate fixed to the end of the springs away from the groove.

[0008] By adopting the above technical solution, the heat insulation plate inside the furnace body extends out of the furnace body. Therefore, after the tractor moves into the furnace body, the baffle abuts against the end face of the furnace body. After the baffle abuts against the heat insulation plate, the heat insulation plate abuts against the heat insulation cotton plate, causing the internal spring to compress. Then the spring rebounds, making the heat insulation cotton plate tightly fit against the heat insulation plate, increasing the overall sealing of the trolley furnace.

[0009] Furthermore, a telescopic rubber ring is fixed inside the insertion hole, and the telescopic rubber ring has a through hole for the round head to pass through.

[0010] By adopting the above technical solution, after the baffle abuts against the furnace body, the round head on the baffle enters along the inside of the insertion hole. The round head abuts against the internal limit switch, while the telescopic rubber ring inside the insertion hole binds the outside of the insertion rod, increasing the sealing between the insertion rod and the insertion hole.

[0011] Furthermore, the insertion hole is connected to a placement groove, and a fixing groove is provided at the bottom of the placement groove.

[0012] By adopting the above technical solution, it is convenient to place the internal electrical components.

[0013] Furthermore, a limit switch is fixed inside the placement slot, and the limit switch is positioned corresponding to the plug hole. A cylinder is fixed inside the fixing slot, and a piston rod is connected to the end of the cylinder away from the fixing slot. A wedge block is fixed to the end of the piston rod away from the cylinder, and the wedge block is inclined towards the limit switch end. Furthermore, the cylinder is electrically connected to the limit switch.

[0014] By adopting the above technical solution, during operation, the tractor moves towards the furnace body, and the baffle gradually comes into contact with the furnace body. After the baffle comes into contact with the furnace body, the round head on the baffle enters along the insertion hole and comes into contact with the internal limit switch. The limit switch opens the cylinder, and the cylinder drives the piston rod to push out, thereby driving the wedge block to move upward and come into contact between the round head and the insertion rod. As the wedge block moves, the wider part of the wedge block contacts the round head, thereby driving the round head to move towards the placement groove, and then driving the baffle to move towards the furnace body, improving the sealing performance of the baffle and further increasing the overall sealing performance of the bogie furnace.

[0015] In summary, the beneficial technical effects of this utility model are as follows:

[0016] 1. The first sealing element is adopted. The heat insulation plate inside the furnace body extends out of the furnace body. Therefore, after the tractor moves into the furnace body, the baffle abuts against the end face of the furnace body. After the baffle abuts against the heat insulation plate, the heat insulation plate abuts against the heat insulation cotton plate, which compresses the internal spring. Then the spring rebounds, which makes the heat insulation cotton plate tightly fit against the heat insulation plate, increasing the overall sealing of the trolley furnace.

[0017] 2. A wedge block is used. During operation, the tractor moves towards the furnace body, and the baffle gradually comes into contact with the furnace body. After the baffle comes into contact with the furnace body, the round head on the baffle enters through the insertion hole and comes into contact with the internal limit switch. The limit switch opens the cylinder, and the cylinder drives the piston rod to push out, which in turn drives the wedge block to move upward and come into contact between the round head and the insertion rod. As the wedge block moves, the wider part of the wedge block contacts the round head, which in turn drives the round head to move towards the placement groove, which in turn drives the baffle to move towards the furnace body, improving the sealing performance of the baffle and further increasing the overall sealing performance of the bogie furnace.

[0018] 3. A limit switch is used, which automatically triggers the movement of the wedge block when the baffle moves, thereby automatically engaging the baffle with the furnace body. This results in a high degree of automation and convenient operation. Attached Figure Description

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.

[0026] 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.

[0027] Please see Figure 1-4 The present invention provides a technical solution comprising: a furnace body 1, a tractor 2 slidably connected inside the furnace body 1, a baffle 3 fixed at the end of the tractor 2 away from the furnace body 1, a groove 4 inside the baffle 3, a first sealing element elastically connected inside the groove 4, a heat insulation plate 5 fixed inside the furnace body 1, the end of the heat insulation plate 5 away from the furnace body 1 extending out of the furnace body 1, and the end of the heat insulation plate 5 extending out of the furnace body 1 abutting against the first sealing element, and second sealing elements provided on both sides of the first sealing element, the second sealing element including a rod 6 fixed on the baffle 3, a round head 7 fixed at the end of the rod 6 away from the baffle 3, and a insertion hole 8 provided on the side of the furnace body 1 corresponding to the position of the round head 7.

[0028] Specifically, the first sealing element includes a spring 9 fixed inside the groove 4. Several springs 9 are provided, and the several springs 9 are evenly distributed inside the groove 4. A heat insulation cotton plate 10 is fixed to the ends of the several springs 9 away from the groove 4.

[0029] In this embodiment, the heat insulation plate 5 inside the furnace body 1 extends out of the furnace body 1. Therefore, after the tractor 2 moves into the furnace body 1, the baffle 3 abuts against the end face of the furnace body 1. After the baffle 3 abuts against the heat insulation plate 5, the heat insulation plate 5 abuts against the heat insulation cotton plate 10, causing the internal spring 9 to compress. Then the spring 9 rebounds, causing the heat insulation cotton plate 10 to fit tightly against the heat insulation plate 5, increasing the overall sealing of the trolley furnace.

[0030] Meanwhile, a telescopic rubber ring 11 is fixed inside the insertion hole 8, and the telescopic rubber ring 11 has a through hole for the round head 7 to pass through.

[0031] The insertion hole 8 is connected to the placement groove 12, and the bottom of the placement groove 12 is provided with a fixing groove 13.

[0032] A limit switch 14 is fixed inside the placement slot 12. The limit switch 14 is set at the position corresponding to the plug hole 8. A cylinder 15 is fixed inside the fixing slot 13. A piston rod 16 is connected to the end of the cylinder 15 away from the fixing slot 13. A wedge block 17 is fixed to the end of the piston rod 16 away from the cylinder 15. The wedge block 17 is inclined toward the end of the limit switch 14.

[0033] The cylinder 15 is electrically connected to the limit switch 14.

[0034] After the baffle 3 comes into contact with the furnace body 1, the round head 7 on the baffle 3 enters through the insertion hole 8. The round head 7 comes into contact with the limit switch 14 inside. At the same time, the telescopic rubber ring 11 inside the insertion hole 8 is bound to the outside of the insertion rod 6. After the round head 7 comes into contact with the limit switch 14, the limit switch 14 opens the cylinder 15. The cylinder 15 drives the piston rod 16 to push out, which in turn drives the wedge block 17 to move upward and come into contact between the round head 7 and the insertion rod 6. As the wedge block 17 moves, the wider part of the wedge block 17 contacts the round head 7, which in turn drives the round head 7 to move toward the placement groove 12, which in turn drives the baffle 3 to move toward the side of the furnace body 1, improving the sealing performance of the baffle 3.

[0035] The working principle of this utility model is as follows: During operation, the tractor 2 moves towards the furnace body 1, and the baffle 3 gradually comes into contact with the furnace body 1. After the baffle 3 comes into contact with the furnace body 1, the round head 7 on the baffle 3 enters through the insertion hole 8. The round head 7 comes into contact with the internal limit switch 14. At the same time, the telescopic rubber ring 11 inside the insertion hole 8 is bound to the outside of the insertion rod 6. After the round head 7 comes into contact with the limit switch 14, the limit switch 14 opens the cylinder 15. The cylinder 15 drives the piston rod 16 to push out, thereby driving the wedge-shaped... Block 17 moves upward and abuts against the round head 7 and the insertion rod 6. As the wedge block 17 moves, the wider part of the wedge block 17 contacts the round head 7, thereby driving the round head 7 to move towards the inside of the placement groove 12, which in turn drives the baffle 3 to move towards the furnace body 1 side, improving the sealing performance of the baffle 3. At the same time, the heat insulation plate 5 abuts against the heat insulation cotton plate 10, causing the internal spring 9 to compress. Then the spring 9 rebounds, making the heat insulation cotton plate 10 tightly adhere to the heat insulation plate 5, further increasing the overall sealing performance of the bogie furnace.

[0036] In particular, in this embodiment, a cover plate can be provided on the outside of the placement slot to facilitate subsequent maintenance.
