DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-4, an annealing furnace that is easy to disassemble, includes a furnace body 1 and a lining 2, a rotating groove 3 is provided on the bottom wall of the furnace body 1, a screw 4 is rotatably provided in the rotating groove 3, a power mechanism connected with the screw 4 is provided on the outer wall of the furnace body 1, a nut 8 is provided on the threaded sleeve of the outer wall of the screw 4, a connecting frame 5 is provided on the nut 8 through a synchronous mechanism, the connecting frame 5 is arranged in the rotating groove 3 through a disassembly and assembly mechanism, a disassembly and assembly port 15 connected with the rotating groove 3 is provided on the bottom wall of the furnace body 1, a connecting frame 6 connected with the lining 2 is provided on the connecting frame 5, and a limiting frame 7 cooperating with the connecting frame 6 is provided on the bottom wall of the furnace body 1.

[0022] The power mechanism includes a driving motor arranged on the outer wall of the furnace body 1, and the output shaft of the driving motor is fixedly connected to the screw 4 in the rotating groove 3. The driving motor is a power device of the screw 4. Starting the driving motor can drive the screw 4 to rotate.

[0023] The synchronization mechanism includes a synchronization block 12 arranged on the outer wall of the nut 8, and the surface of the connecting frame 5 in contact with the nut 8 is provided with an arc-shaped contact surface, and the arc-shaped contact surface is provided with a synchronization groove 13 corresponding to the synchronization block 12. Figure 3 As shown, when the synchronization block 12 is in the synchronization groove 13 , the coupling frame 5 can move along the screw rod 4 along with the nut 8 .

[0024] The disassembly and assembly mechanism includes a disassembly and assembly plate 9 arranged on the outer walls on both sides of the connecting frame 5, and a disassembly and assembly groove 14 corresponding to the disassembly and assembly plate 9 is arranged on the inner walls on both sides of the rotating groove 3. Since the disassembly and assembly plate 9 and the disassembly and assembly groove 14 are arranged, the connecting frame 5 will not be vertically separated from the nut 8, which plays a limiting role.

[0025] A limiting rod 10 is provided in the rotating groove 3 , and the limiting rod 10 is arranged parallel to the screw rod 4 . The limiting rod 10 slides through the nut 8 , and the limiting rod 10 has a limiting function, which realizes the limiting of the nut 8 to prevent it from rotating with the screw rod 4 .

[0026] The limit frame 7 is U-shaped, and limit grooves are provided on the two surfaces where the limit frame 7 contacts the connecting frame 6. The outer walls on both sides of the connecting frame 6 are provided with limit strips 11 corresponding to the limit grooves. The length of the limit strips 11 is limited. When the disassembly plate 9 moves to correspond to the disassembly opening 15, the limit strips 11 have been separated from the limit grooves.

[0027] When the utility model is in use, when the lining 2 needs to be replaced, the driving motor is started, and the driving motor can drive the screw 4 to rotate. When the screw 4 rotates, the nut 8 on its outer wall can drive the connecting frame 5 to move, and the connecting frame 5 drives the disassembly plate 9 to move in the rotating groove 3. When the connecting frame 5 drives the disassembly plate 9 to move to correspond to the disassembly opening 15, the limiting strip 11 on the connecting frame 6 has been disengaged from the limiting groove on the limiting frame 7. At this time, the connecting frame 5 and the connecting frame 6 both lose vertical restrictions, and the lining 2 is completely disengaged from the furnace body 1. At this time, the above-mentioned components are vertically disassembled from the furnace body 1, and the lining 2 can be conveniently replaced, cleaned, and maintained.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
