Description

Technical Field

[0001] This application belongs to the technical field of heat treatment industrial furnace equipment, and in particular relates to a furnace door structure for a stacked heat treatment industrial furnace. Background Technology

[0002] Currently, some industrial heat treatment furnaces use top-and-bottom split doors. These doors not only occupy a large amount of space with low space utilization, but are also inconvenient to install and adjust. Furthermore, this top-and-bottom split door structure requires a motor and chain to drive the door, and it is very unstable when opening and closing, making installation and adjustment complex. During use, if the chain is damaged, the furnace becomes unusable and maintenance is also inconvenient. Summary of the Invention

[0003] This application provides a furnace door structure for stacked heat treatment industrial furnaces, especially suitable for furnace doors used in industrial furnaces that are stacked vertically. It solves the technical problems of existing vertically split furnace door structures, which not only have poor working stability, but also have inconvenient safety adjustments, large space occupation, and low efficiency.

[0004] To solve at least one of the above-mentioned technical problems, the technical solution adopted in this application is:

[0005] A furnace door structure for a stacked heat treatment industrial furnace, suitable for double-layer stacked industrial furnaces, includes a furnace door body stacked vertically and a mounting frame adapted to the furnace door body. The furnace door body includes left and right double doors, both of which are mounted on the mounting frame. The width of the mounting frame is greater than the width of the industrial furnace. The double doors can be aligned and opened and closed along the width direction of the mounting frame.

[0006] Furthermore, the mounting brackets, which are placed vertically, are stacked and connected to the crossbeam, and the furnace door bodies, which are placed vertically, are all placed independently of each other.

[0007] Furthermore, the top beam and bottom beam of the mounting frame are each provided with two sets of aligned slide rails and sliding cylinders, and the piston end of the sliding cylinder is positioned opposite each other.

[0008] Furthermore, the width of the mounting bracket is at least twice the width of the furnace door.

[0009] Furthermore, the cylinder end of the sliding cylinder is fixed to the top beam and the bottom beam by a mounting seat, and its piston end is movably connected to the double door by a connector provided on the outer wall of the double door.

[0010] Furthermore, rollers that cooperate with the slide rail are provided at the top and bottom of the double doors. The sliding cylinder drives the piston to move the double doors in opposite directions or to the left and right along the length of the slide rail, driven by the rollers.

[0011] Furthermore, each of the double doors is provided with at least two of the rollers at the top or bottom, and they are arranged symmetrically.

[0012] Furthermore, each of the double doors is provided with a push assembly on its outer side to press against the furnace door, including two push handles, a motor for driving the push handles, and a fixing seat for fixing the push handles. The fixing seat is fixed to the outer wall of the furnace body and is located near the furnace door. The push handles are pivotally connected to the fixing seat via a rotating shaft and are driven by the motor. The push handles can pass through the thickness direction of the mounting bracket to engage with the outer wall of the double doors and gradually press against the double doors to press against the furnace door.

[0013] Furthermore, the pusher can be driven to rotate axially via a pivot, so that when the double doors are opened, it can be controlled to rotate outward in advance to avoid the double doors opening in opposite directions.

[0014] Furthermore, the push handle has a C-shaped structure, and the length of its contact section with the double door is less than the length of its connection section with the pivot.

[0015] The furnace door structure for stacked heat treatment industrial furnaces designed in this application is particularly suitable for use in stacked industrial furnaces. It employs a left-right opening furnace door structure and optimizes its drive mechanism, which not only reduces the overall height of the stacked industrial furnace but also improves the overall space utilization. The overall structure is simple, has good sealing performance, stable and reliable operation, low maintenance costs, and is suitable for double-layer placement of different furnace types.

[0027] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0028] This embodiment proposes a furnace door structure for a stacked heat treatment industrial furnace, such as... Figure 1 As shown, this is applicable to double-layer stacked industrial furnaces, including furnace door bodies 20 stacked vertically and mounting brackets 30 adapted to the furnace door bodies 20. The upper and lower mounting brackets 30 are connected by a crossbeam 50, and the upper and lower furnace door bodies 20 operate independently without interfering with each other. Since the upper and lower furnace door bodies 20 and mounting brackets 30 have the same structure, the furnace door structure in a single-layer industrial furnace will be described in detail.

[0029] like Figure 2-3 As shown, the furnace door 20 includes left and right double doors, both mounted on a mounting frame 30. The width of the mounting frame 30 is greater than the width of the industrial furnace, so that there is sufficient horizontal movement space in the mounting frame 30 to accommodate the sliding double doors when they are opened. The mounting frame 30 itself is a rectangular hollow frame, which is only used to fix the position of the double doors and guide their sliding. Preferably, the horizontal width of the mounting frame 30 is at least twice the overall width of the furnace door 20, so that the double doors can be aligned and opened and closed along the width direction of the mounting frame 30 to allow space of the same width as the furnace door to be used for pushing materials or other platforms.

[0030] The top and bottom beams of the mounting frame 30 are each equipped with two sets of aligned slide rails 31 and sliding cylinders 32, with the piston ends of the sliding cylinders 32 facing each other. The cylinder end of the sliding cylinder 32 is fixed to the top and bottom beams of the mounting frame 30 via a mounting base 33, and its piston end is movably connected to the double door via a connector 35 provided on the outer wall of the double door. Thus, when the double door is opened and closed, the sliding cylinders 32 drive the double door to slide synchronously in the same direction or in opposite directions along the length of the slide rails 31.

[0031] To improve the stability of the sliding of the double doors, rollers 34 that cooperate with the slide rail 31 are provided at the top and bottom of the double doors. The sliding cylinder 32 drives the piston and, through the connecting piece 35, drives the double doors to move in opposite directions or to each other along the length of the slide rail 31 via the rollers. Each double door is provided with at least two rollers at the top or bottom, and they are arranged symmetrically.

[0032] like Figure 4-5 As shown, each double door is provided with a push assembly 40 on its outer side to press against the furnace door. Each push assembly 40 includes two pushers 41, a motor 42 for driving the pushers 41 to work synchronously, and a fixing seat 43 for fixing the pushers 41. The fixing seat 43 is fixed to the outer wall of the furnace body 10 and is located near the furnace door. The pushers 41, which are arranged vertically, are pivotally connected to the fixing seat 43 via a pivot 44 and are driven by the motor 42. The pushers 41 can pass through the thickness direction of the mounting bracket 30 to engage with the outer wall of the double door and are gradually pulled against the double door to make the furnace door body 20 press against the furnace door.

[0033] Furthermore, the push handle 41 can be axially rotated by the pivot 44, so that when the double doors are opened, the push handle 41 can be rotated outward in advance to avoid the double doors opening in opposite directions. The motor 42 is a pneumatic drive mechanism, which can drive the push handle 41 to push against the double doors when it contacts the door surface. This is a common structure in the field, and its detailed operation diagram is omitted here.

[0034] Furthermore, the push handle 41 has a C-shaped structure, and the length of its contact section with the double doors is shorter than the length of its connection section with the pivot 44. This is to improve the operability of the push handle 41 in pressing against the double doors. A flat panel is provided at the end of the push handle 41 that contacts the double doors. This panel can be circular, polygonal, or square, and its purpose is to directly contact the outer wall surface of the double doors, thereby improving the safety and stability of pressing against the double doors.

[0035] Furthermore, sealing strips are provided on the contact surfaces of the two double doors and their contact surfaces with the furnace door to improve the sealing performance when in contact with the furnace door.

[0036] The furnace door structure for stacked heat treatment industrial furnaces designed in this application is particularly suitable for use in stacked industrial furnaces. It employs a left-right opening furnace door structure and optimizes its drive mechanism, which not only reduces the overall height of the stacked industrial furnace but also improves the overall space utilization. The overall structure is simple, has good sealing performance, stable and reliable operation, low maintenance costs, and is suitable for double-layer placement of different furnace types.

[0037] The embodiments of this application have been described in detail above. These descriptions are merely preferred embodiments and should not be construed as limiting the scope of this application. All equivalent variations and modifications made within the scope of this application should still fall within the patent coverage of this application.
