[0002] The main function of the annealing furnace is to change the structure and properties of the material by heating and controlling the cooling process. It plays an important role in applications in different fields and improves product quality and performance. The annealing furnace consumes a lot of energy during operation, such as gas, electricity, etc. Especially in industrial production, due to the large scale and strong continuity of production, the energy consumption of the annealing furnace is huge, so effective energy-saving measures need to be taken to reduce energy consumption and operating costs.

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0024] like Figures 1 to 4 As shown, the utility model is an energy-saving annealing furnace comprising: an annealing furnace 1, a trolley 2 movably installed on the annealing furnace 1, the trolley 2 is used for carrying and transporting materials, a switch component 4 for preventing temperature loss when replacing materials, a heat recovery component 5 for recovering and reusing the temperature in the annealing furnace 1, a hook 3 is fixedly connected to the upper surface of the annealing furnace 1, and a plurality of groups of hooks 3 are arranged on the surface of the annealing furnace 1, and the annealing furnace 1 is lifted by the hook 3 to transfer its position.

[0025] The switch assembly 4 includes a support frame 41 fixedly connected to the annealing furnace 1, a forward and reverse motor 42 fixedly connected to the support frame 41, a rotating rod 43 fixedly connected to the output end of the forward and reverse motor 42, a support plate 44 rotatably connected to the rotating rod 43, the bottom surface of the support plate 44 is fixedly connected to the support frame 41, a winding roller 45 fixedly installed on the rotating rod 43, a wire rope 46 fixedly installed on the winding roller 45, and a furnace door 47 fixedly connected to the wire rope 46. The forward and reverse motor 42 drives the rotating rod 43 to rotate, and then drives the winding roller 45 to retract and release the wire rope 46, so that the furnace door 47 can be raised and lowered, so that the furnace door 47 can be switched between the open position and the closed position. When the trolley 2 drives the material to leave the annealing furnace 1, the furnace door 47 is in the open position, so that the trolley 2 carries the material to leave, and after the trolley 2 moves out of the annealing furnace 1, the furnace door 47 falls to the closed position, so as to avoid the loss of temperature inside the annealing furnace 1 and waste of resources.

[0026] The heat recovery component 5 includes a sealing component for preventing heat loss and a transfer component for recovering heat. When the annealing furnace 1 is in use, the sealing component seals the opening on the shell of the annealing furnace 1 to prevent heat loss. When the annealing furnace 1 is shut down or overhauled, the temperature inside the annealing furnace 1 is transferred outward through the air outlet pipe 516 by the transfer component, which can be used for preheating materials and heating the inside of the annealing furnace 1 to be used, thereby preventing natural heat loss from causing energy waste and increasing the operating costs of the enterprise.

[0027] The sealing assembly includes a groove 51 provided on the annealing furnace 1, a sealing gasket 56 placed inside the groove 51, a through hole 52 provided on the groove 51, a hole for the temperature inside the annealing furnace 1 to flow outward, a positioning groove 53 provided on the surface of the through hole 52, a positioning block 54 installed on the positioning groove 53, the size of the positioning groove 53 matches the size of the positioning block 54, a heat insulating block 55 fixedly connected to the positioning block 54, the heat insulating block 55 is a refractory brick, a sealing gasket 56 covering the surface of the heat insulating block 55, the sealing gasket 56 is a refractory fiber material, a rotating bracket 57 fixedly connected to the annealing furnace 1, a cover 58 rotatably connected to the rotating bracket 57, and a heat insulating block 55 fixedly connected to the annealing furnace 1. The fixing block 59 on the blocking cover 58 is threadedly connected to the fastening bolt 510 on the fixing block 59, and the insulation block 55 is placed inside the through hole 52. At the same time, the positioning block 54 enters the positioning groove 53, and then the sealing gasket 56 is covered on the surface of the insulation block 55. The blocking cover 58 is then rotated through the rotation connection with the rotating bracket 57 to cover the sealing gasket 56, and then the fastening bolt 510 is used to thread the fixing block 59 and the annealing furnace 1 to complete the fixing of the blocking cover 58. The blocking cover 58 can fix the sealing gasket 56 to prevent the sealing gasket 56 from shifting in position, causing the temperature in the annealing furnace 1 to dissipate through the gap between the insulation block 55 and the through hole 52.

[0028] The transfer assembly includes a connecting block 511 installed on the positioning groove 53, a fixing bolt 512 threadedly connected to the connecting block 511, a connecting tube 513 fixedly connected to the connecting block 511, the connecting tube 513 connecting the through hole 52 and the air inlet pipe 514, the air inlet pipe 514 flange-connected to the connecting tube 513, an air extraction pump 515 flange-connected to one end of the air inlet pipe 514, and an air outlet pipe 516 flange-connected to the air outlet end of the air extraction pump 515. When temperature transfer is required, the connecting tube 513 is inserted into the through hole 52, and the connecting block 511 is allowed to enter the positioning groove 53 at the same time, and then the connecting block 511 is fixed with the fixing bolt 512, and then the air extraction pump 515 is started to extract the temperature inside the annealing furnace 1 to the air outlet pipe 516 through the air inlet pipe 514, and then the air outlet pipe 516 is discharged to a designated location, thereby recycling the temperature inside the annealing furnace 1 to avoid energy waste.

[0029] Working principle: The forward and reverse motor 42 drives the rotating rod 43 to rotate, and then drives the winding roller 45 to retract and release the wire rope 46, so that the furnace door 47 can be raised and lowered, so that the furnace door 47 can be switched between the open position and the closed position. When the trolley 2 drives the material to leave the annealing furnace 1, the furnace door 47 is in the open position, so that the trolley 2 carries the material to leave. After the trolley 2 moves out of the annealing furnace 1, the furnace door 47 falls to the closed position to avoid the loss of temperature inside the annealing furnace 1 and waste of resources. When the annealing furnace 1 is in use, the insulation block 55 is placed in the through hole 52, and the positioning block 54 is placed in the positioning groove 53. Then the sealing gasket 56 is covered on the surface of the insulation block 55, and then the cover 58 is rotated with the rotating bracket 57. After the connection is rotated, the sealing gasket 56 is covered, and then the fastening bolts 510 are used to thread the fixing block 59 and the annealing furnace 1 to complete the fixation of the baffle cover 58. The baffle cover 58 can fix the sealing gasket 56 to prevent the position of the sealing gasket 56 from shifting, causing the temperature in the annealing furnace 1 to dissipate through the gap between the insulation block 55 and the through hole 52. When the annealing furnace 1 is shut down for maintenance, the connecting tube 513 is inserted into the through hole 52, and the connecting block 511 is inserted into the positioning groove 53 at the same time, and then the connecting block 511 is fixed with the fixing bolts 512, and then the vacuum pump 515 is started to pump the temperature inside the annealing furnace 1 to the outlet pipe 516 through the inlet pipe 514, and then discharged to the designated location through the outlet pipe 516.
