[0002] The trolley type roasting furnace is a common heat treatment equipment, which is widely used in steel, nonferrous metals, machinery manufacturing and other industries. The sealing structure of the trolley furnace directly affects the working temperature, temperature distribution, heat loss and other factors in the furnace. Therefore, it is very important to optimize the sealing structure and ensure its sealing performance and working efficiency.
[0003] Traditional trolley-type roasting furnaces are mostly sand-sealed during use, using sand to seal the gap between the trolley and the roasting furnace, and further increased the sealing effect through sand sealing knives. However, the friction between the sand sealing knives and the sand will generate heat and cause large wear, so measures need to be taken to cool the sand sealing knives. Although the sealing performance is good, the maintenance cost is high, and it is necessary to rely on additional external auxiliary sealing devices, which increases the complexity and manufacturing cost of the equipment.

DETAILED DESCRIPTION
[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0024] Embodiment 1
[0025] Combined with Figure 1 A trolley-type roasting furnace with a self-sealing function comprises a roasting furnace 1, wherein the four corners of the bottom of the roasting furnace 1 are provided with supporting legs 2, an opening 4 is provided on one side of the roasting furnace 1, at least one guide rail 5 is provided below the roasting furnace 1, and a trolley 6 which cooperates with the guide rail 5 and is slidably connected is provided above the guide rail 5.
[0026] Through the above structure, the trolley 6 uses the guide rail 5 to enter the roasting furnace through the opening 4 to perform roasting operations on the metal material.
[0027] Combined with Figure 1 and attached Figure 2 A flue gas purification device 3 is provided at the top of the roasting furnace 1, and the trolley 6 moves along the guide rail 5 through an external driving device.
[0028] Through the above structure, the flue gas purification device 3 can be used to purify the flue gas in the roasting furnace 1, ensuring that harmful gases generated during roasting are not directly discharged into the environment.
[0029] Embodiment 2
[0030] Combined with Figure 2 , Attachment Figure 4 and attached Figure 5 A baffle door 7 is provided on one side of the trolley 6, a sealing plate 8 used in conjunction with the opening 4 is provided on one side of the baffle door 7, a self-sealing structure is provided between the baffle door 7 and the opening 4, and a self-locking structure is provided between the baffle door 7 and the roasting furnace 1.
[0031] Through the above structure, as the trolley 6 moves, the baffle door 7 and the sealing plate 8 follow the movement, and the opening 4 can be directly blocked. In addition, a self-sealing and self-locking structure is provided between the baffle door 7 and the roasting furnace 1, without the need for external equipment, with a simple structure and low maintenance cost.
[0032] Combined with Figure 4 and attached Figure 5 The self-sealing structure includes a sealing ring 9 arranged on one side of the baffle 7 and located around the sealing plate 8, and a sealing groove 10 used in conjunction with the sealing ring 9 is provided around the opening 4.
[0033] Through the above structure, the sealing ring 9 is directly and tightly embedded in the sealing groove 10, so as to seal the baffle door 7 and prevent air leakage during baking.
[0034] Combined with Figure 3 and attached Figure 4 The self-locking structure includes a fixing plate 11 arranged on one side of the roasting furnace 1 and located on both sides of the opening 4, a base 12 is provided on one side of the fixing plate 11, an arc-shaped slot 13 is provided on the base 12, a buckle 14 is hingedly provided on the base 12, and limiting columns 16 used to cooperate with the arc-shaped slot 13 and the buckle 14 are provided on both sides of the baffle door 7, and a protrusion 15 for convenient rotation is provided on one side of the buckle 14.
[0035] Through the above structure, as the baffle door 7 continues to move, the limit posts 16 on both sides follow the movement and slowly approach the arc-shaped slot 13 on the base 12. Since both sides of the buckle 14 are arc-shaped, the limit posts 16 directly squeeze the buckle 14. Since the buckle 14 base 12 is hinged, as the limit post 16 continues to move forward, the buckle 14 rotates upward, so that the limit post 16 completely enters the arc-shaped slot 13. At this time, the buckle 14 moves down again under the action of gravity to self-lock the limit post 16.
[0036] Combined with Figure 1 Convex sliders are provided on both sides of the trolley 6, and concave slide grooves used in conjunction with the convex sliders are provided on both sides of the opening 4, and sealing patches are provided on the inner walls of the concave slide grooves.
[0037] Through the above structure, as the trolley 6 continues to move, the convex slider slowly enters the concave slide groove in the opening 4, and the inner wall of the concave slide groove is provided with a sealing patch, which further improves the overall self-sealing property.
[0038] When the utility model is implemented:
[0039] The metal to be roasted is placed on the trolley 6, and the external driving device is started to drive the trolley 6 to move on the guide rail 5. At this time, the baffle door 7 follows the movement and slowly approaches the opening 4. At this time, the sealing ring 9 is directly and tightly embedded in the sealing groove 10 to seal the baffle door 7 to prevent air leakage during roasting. In addition, the convex slider slowly enters the concave slide groove in the opening 4, and the inner wall of the concave slide groove is provided with a sealing patch, which further improves the self-sealing property as a whole.
[0040] At the same time, as the baffle door 7 continues to move, the limit posts 16 on both sides follow the movement and slowly approach the arc-shaped slot 13 on the base 12. Since both sides of the buckle 14 are arc-shaped, the limit posts 16 directly squeeze the buckle 14. Since the buckle 14 base 12 is hinged, as the limit posts 16 continue to move forward, the buckle 14 rotates upward, so that the limit posts 16 completely enter the arc-shaped slot 13. At this time, the buckle 14 moves down again under the action of gravity to self-lock the limit posts 16.
[0041] The overall structure is simple and self-sealing, which reduces maintenance costs.
