Description

Technical Field

[0001] This utility model relates to the technical field of drying ovens, and more specifically, to a lifting oven door for a drying oven. Background Technology

[0002] Drying ovens are very common equipment used in industrial production for drying materials. During use, materials are placed in the oven body, and the oven body is heated to achieve the drying effect. To prevent heat loss, drying ovens are usually sealed structures (equipped with dedicated gas pipelines), and the sealing is mainly achieved through the oven door.

[0003] There are many types of furnace door structures, with lifting furnace doors being a very common one. These doors are mainly driven to rise and fall by a motor. In order to ensure a good seal, the connection between the furnace door and the furnace body is quite tight. However, during long-term use, a lot of impurities accumulate at the joint between the furnace door and the furnace body. In addition, the furnace door and furnace body are in a high-humidity environment and rust at a fast rate, which makes the furnace door not smooth during the rising and falling process and easy to get stuck. This has a significant impact on production efficiency. Therefore, it is necessary to design a furnace door structure that opens and closes more smoothly. Utility Model Content

[0004] The purpose of this utility model is to provide a lifting oven door for a drying oven, which can effectively ensure that the sealing plate remains smooth during the lifting process.

[0005] This utility model is achieved through the following technical solution: The lifting furnace door of the drying oven of this utility model includes a furnace body, a sliding groove provided on both sides of the opening side of the furnace body, a sealing plate slidably provided in the sliding groove, a first driving device for driving the sealing plate to lift and lower, a groove opened on the side of the sliding groove away from the furnace body, a clamping plate slidably provided in the groove, and a second driving device for driving the clamping plate to move closer to / away from the sealing plate; the width of the sliding groove is greater than the thickness of the sealing plate.

[0006] Furthermore, the first driving device includes a winding roller disposed on the upper side of the furnace body, a motor connected to the winding roller, and a pull rope wound on the winding roller; the pull rope is connected to the upper end of the sealing plate.

[0007] Furthermore, the first driving device also includes a pulley located directly above the sealing plate; the pull rope is arranged to pass around the pulley.

[0008] Furthermore, the second drive device includes a telescopic cylinder connected to the clamping plate.

[0009] Furthermore, the second driving device also includes a horizontally arranged pull rod connected to the clamping plate, a fixing block fixedly disposed on the side wall of the furnace body, and a sliding hole opened on the fixing block; the pull rod is slidably disposed in the sliding hole, the cylinder body of the telescopic cylinder is hinged to the side wall of the furnace body, and the telescopic rod of the telescopic cylinder is hinged to the side of the pull rod away from the clamping plate.

[0010] Furthermore, the pull rod includes a first pull rod and a second pull rod arranged coaxially; the first pull rod and the second pull rod are connected by a spring; the first pull rod is connected to the clamping plate, and the second pull rod is hinged to the telescopic rod of the telescopic cylinder.

[0011] Furthermore, the fixing block is provided in pairs, and both the first pull rod and the second pull rod are slidably connected to the fixing block.

[0012] Furthermore, the bottom of the opening side of the furnace body is provided with multiple slots, and horizontally arranged needle rollers are rotatably arranged in the slots; the axial direction of the needle rollers is perpendicular to the moving direction of the clamping plate.

[0013] The technical solution of this utility model has at least the following advantages and beneficial effects: The lifting furnace door of this utility model seals the furnace body with a sealing plate, thus functioning as a furnace door. The sealing plate can be raised and lowered by a first driving device to open and close the furnace body. Before the sealing plate rises, the clamping plate is moved away from the sealing plate by a second driving device, and the clamping plate loses its force on the sealing plate. Since the width of the slide groove is significantly greater than the thickness of the sealing plate, the sealing plate can slide smoothly up and down in the slide groove. When the sealing plate needs to seal the furnace body, it is lowered, and then the second driving device drives the clamping plate to clamp the sealing plate, so that the sealing plate is tightly attached to the furnace body. In this way, even if the slide groove, furnace body, and other structures are corroded, slightly deformed, or even if there are some impurities in the slide groove, the sealing plate can still move smoothly up and down, effectively avoiding the sealing plate getting stuck, reducing the equipment failure rate, reducing maintenance costs, and ensuring the sealing effect of the sealing plate.

Detailed Implementation

[0018] Example

[0019] The following description, in conjunction with specific embodiments, further illustrates the point, as shown in the appendix. Figure 1 -Appendix Figure 3 As shown, the lifting oven door of this embodiment includes an oven body 10, sliding grooves 11 on both sides of the opening side of the oven body 10, a sealing plate 12 slidably disposed in the sliding grooves 11, a first driving device 20 for driving the sealing plate 12 to rise and fall, a groove 15 formed on the side of the sliding groove 11 away from the oven body 10, a clamping plate slidably disposed in the groove 15, and a second driving device 30 for driving the clamping plate to move closer to / away from the sealing plate 12; the width of the sliding groove 11 is greater than the thickness of the sealing plate 12. Specifically, the sealing plate 12 seals the oven body 10, achieving the function of an oven door. The first driving device 20 can drive the sealing plate 12 to rise and fall, achieving the function of opening and closing the oven body 10. Before the sealing plate 12 rises, the second driving device 30 first moves the clamping plate away from the sealing plate 12, and the clamping plate loses its force on the sealing plate 12. Since the width of the sliding groove 11 is significantly greater than the thickness of the sealing plate 12, the sealing plate 12 can slide up and down very smoothly in the sliding groove 11. When the sealing plate 12 needs to seal the furnace body 10, the sealing plate 12 is lowered, and then the second drive device 30 drives the clamping plate to clamp the sealing plate 12, so that the sealing plate 12 is tightly attached to the furnace body 10. In this way, even if the slide 11, furnace body 10 and other structures are corroded, slightly deformed, or even if there are some impurities in the slide 11, the sealing plate 12 can still move up and down smoothly, which can effectively prevent the sealing plate 12 from getting stuck, reduce the failure rate of the equipment, reduce maintenance costs, and also ensure the sealing effect of the sealing plate 12.

[0020] In this embodiment, the first driving device 20 includes a winding roller 21 located on the upper side of the furnace body 10, a motor 22 connected to the winding roller 21, and a pull rope 23 wound around the winding roller 21; the pull rope 23 is connected to the upper end of the sealing plate 12. The first driving device 20 also includes a pulley located directly above the sealing plate 12; the pull rope 23 is arranged around the pulley. Specifically, by driving the winding roller 21 to rotate through the motor 22, the winding and unwinding of the pull rope 23 can be achieved, thereby achieving the purpose of pulling the sealing plate 12 up and down. A counterweight can also be provided at the end of the pull rope 23 to reduce the load on the motor 22.

[0021] The second driving device 30 in this embodiment includes a telescopic cylinder 33 connected to the clamping plate. The second driving device 30 also includes a horizontally arranged pull rod connected to the clamping plate, a fixing block 34 fixedly disposed on the side wall of the furnace body 10, and a sliding hole formed in the fixing block 34; the pull rod is slidably disposed in the sliding hole, the cylinder body of the telescopic cylinder 33 is hinged to the side wall of the furnace body 10, and the telescopic rod of the telescopic cylinder 33 is hinged to the side of the pull rod away from the clamping plate. Specifically, by pushing / pulling the pull rod with the telescopic cylinder 33, the clamping plate can clamp / relax the sealing plate 12. The telescopic cylinder 33 can adopt a pneumatic, screw-type, or hydraulic structure.

[0022] In this embodiment, the pull rod includes a first pull rod 31 and a second pull rod 32 coaxially arranged; the first pull rod 31 and the second pull rod 32 are connected by a spring 35; the first pull rod 31 is connected to the clamping plate, and the second pull rod 32 is hinged to the telescopic rod of the telescopic cylinder 33. Specifically, a spring 35 is provided between the first pull rod 31 and the second pull rod 32, which can buffer the force exerted by the clamping plate on the sealing plate 12.

[0023] In this embodiment, a pair of fixing blocks 34 are provided, and the first pull rod 31 and the second pull rod 32 are both slidably connected to the fixing blocks 34. Specifically, the fixing blocks 34 can ensure that the first pull rod 31 and the second pull rod 32 can move horizontally, thereby ensuring that the clamping plate is in full contact with the sealing plate 12.

[0024] In this embodiment, the bottom of the furnace body 10 on the open side is provided with multiple slots 13, and horizontally arranged needle rollers 14 are rotatably mounted in the slots 13; the axial direction of the needle rollers 14 is perpendicular to the moving direction of the clamping plate. Specifically, see attached... Figure 3 As shown, the needle roller 14 can support the sealing plate 12. When the sealing plate 12 moves towards the furnace body 10 under the action of the clamping plate, the needle roller 14 can ensure that the movement of the sealing plate 12 is smoother, so that all parts of the sealing plate 12 are in full contact with the furnace body 10, thus ensuring the sealing effect.

[0025] In summary, the lifting furnace door of the drying oven in this embodiment seals the furnace body 10 with the sealing plate 12, thus functioning as a furnace door. The lifting and lowering of the sealing plate 12 can be driven by the first driving device 20 to open and close the furnace body 10. Before the sealing plate 12 rises, the clamping plate is moved away from the sealing plate 12 by the second driving device 30, and the clamping plate loses its force on the sealing plate 12. Since the width of the slide groove 11 is significantly greater than the thickness of the sealing plate 12, the sealing plate 12 can slide up and down very smoothly in the slide groove 11. When the sealing plate 12 needs to seal the furnace body 10, the sealing plate 12 is lowered, and then the second drive device 30 drives the clamping plate to clamp the sealing plate 12, so that the sealing plate 12 is tightly attached to the furnace body 10. In this way, even if the slide 11, furnace body 10 and other structures are corroded, slightly deformed, or even if there are some impurities in the slide 11, the sealing plate 12 can still move up and down smoothly, which can effectively prevent the sealing plate 12 from getting stuck, reduce the failure rate of the equipment, reduce maintenance costs, and also ensure the sealing effect of the sealing plate 12.
