[0018] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner, and thus only show components related to the present invention.

[0019] Please refer to Figure 1-4 A hoisting-type split deep-well furnace comprises a deep-well furnace body 1, which comprises a movable cavity 2 and a fixed cavity 3. The movable cavity 2 can be unlocked from the fixed cavity 3 by a sliding assembly. A crane 6 is provided directly above the deep-well furnace body 1. The setting direction of the crane 6 is perpendicular to the moving direction of the movable cavity 2. The crane 6 is provided with a mobile electric hoist 61 that can move horizontally. The mobile electric hoist 61 is provided with a lifting rope 62. The workpiece is taken and placed in the deep-well furnace body 1 by the mobile electric hoist 61 and the crane 6.

[0020] When in use, first fix the slender workpiece at the end of the lifting rope 62, and then separate the movable cavity 2 and the fixed cavity 3 through the sliding assembly. At this time, the mobile electric hoist 61 drives the workpiece to move between the movable cavity 2 and the fixed cavity 3; then the sliding assembly runs again to push the movable cavity 2, so that the movable cavity 2 and the fixed cavity 3 are buckled together. After buckling, the movable cavity 2 and the fixed cavity 3 form a complete furnace body, and the temperature in the furnace rises to heat the workpiece.

[0021] After the workpiece is heated, the sliding assembly is driven again to move the movable cavity 2 back in translation. At this time, the movable cavity 2 and the fixed cavity 3 are separated again. After separation, the movable electric hoist 61 drives the workpiece to move outward.

[0022] This process only requires horizontal movement of the workpiece, without the need for vertical lifting, which can greatly shorten the time it takes for the workpiece to enter and exit the furnace. At the same time, it can effectively prevent the temperature loss of the workpiece and ensure that the heated workpiece meets the subsequent quenching requirements.

[0023] Specifically, two parallel guide rails 4 are provided under the deep well furnace body 1, the fixed cavity 3 is fixed on the guide rails 4 by a pad block 41, and the bottom of the movable cavity 2 is provided with a roller 21 that cooperates with the guide rails 4. The sliding assembly includes a steel frame 5 and a hydraulic rod 51. The steel frame 5 is provided between the two guide rails 4, and the hydraulic rod 51 is fixed on one side of the steel frame 5. The output end of the hydraulic rod 51 is fixedly connected to the outer wall of the movable cavity 2.

[0024] When the workpiece is moved in and out by the crane 6, the hydraulic rod 51 pulls the movable chamber 2 to separate the movable chamber 2 from the fixed chamber 3, making it easier for the workpiece to move in and out; when the workpiece needs to be heated, the movable chamber 2 is pushed to engage with the fixed chamber 3, and the roller 21 rolls in the guide rail during the movement of the movable chamber 2.

[0025] The height, specification and size of the movable cavity 2 and the fixed cavity 3 are consistent; it can also be understood that the movable cavity 2 and the fixed cavity 3 are symmetrical structures, and an insulation layer is provided at the opening between the movable cavity 2 and the fixed cavity 3.

[0026] In order to facilitate the smooth entry and exit of the lifting rope, a lifting rope hole 11 is provided at the surface ends of the movable cavity 2 and the fixed cavity 3.

[0027] Furthermore, in order to ensure uniform temperature in the deep-well furnace body 1 (where the movable cavity 2 and the fixed cavity 3 are fastened together), a hot air circulation mechanism is provided in the deep-well furnace body 1 .

[0028] Specifically, the hot air circulation mechanism includes two oppositely arranged split barrels 7, two semicircular guide plates 8 and centrifugal fan blades 9. When the movable chamber 2 and the fixed chamber 3 are buckled together, the two split barrels 7 form a cylinder, and the two guide plates 8 form a disc.

[0029] The two guide plates 8 are fixed in the movable chamber 2 and the fixed chamber 3, respectively. The split barrel 7 is fixed on the guide plates 8, and the two guide plates 8 are provided with corresponding semicircular holes. The centrifugal blades 9 are provided in the semicircular holes. A plurality of through holes 81 are provided on the guide plates 8 between the split barrel 7 and the furnace wall; a circulation channel is formed between the split barrel 7 and the furnace wall.

[0030] In addition, an external motor 10 is provided at the bottom of the fixed cavity 3, and the output shaft of the motor 10 passes through the fixed cavity 3 and is transmission-connected to the centrifugal fan blades 9, wherein the bottom openings of the movable cavity 2 and the fixed cavity 3 are both provided with a semicircular drive hole 12, and the output shaft of the motor extends upward in the drive hole 12.

[0031] When the movable chamber 2 and the fixed chamber 3 are buckled together, a complete deep-well furnace is formed; at this time, the centrifugal blades 9 are arranged between the two guide plates 8; when the motor 10 is running, the centrifugal blades 9 start to rotate.

[0032] See also Figure 5 ; When the centrifugal fan blades 9 rotate, the air in the split barrel 7 will flow to the bottom of the guide plate 8 along with the air flow, and then the air will pass upward through the through holes 81 on the guide plate 8; the hot air rises between the split barrel 7 and the furnace wall, and then enters the bottom of the guide plate 8 from the split barrel 7 again. This cycle can make the temperature in the furnace uniform and ensure that the workpiece is heated evenly.

[0033] In this embodiment, the inner wall of the movable cavity 2, the inner wall of the fixed cavity 3 and the inner and outer walls of the split barrel are all provided with electric heating elements, which are commonly used devices in heating furnaces and will not be described in detail here.

[0034] The length of the deep well furnace is about 20m. Due to the high height and large space inside the furnace, the heated air will be concentrated upward in the furnace, resulting in low temperature in the lower space, which makes the workpiece heated unevenly; therefore, the establishment of the split barrel 7, guide plate 8, centrifugal fan blades 9 and motor 10 can circulate the high-temperature air in the furnace, ensure uniform temperature, and improve the heating quality of the workpiece.

[0035] Based on the above embodiments, the overall structure of the deep well furnace can be installed on the ground without the need for excavation underground, which greatly reduces the construction difficulty and shortens the construction period.

[0036] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
