[0018] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0019] First embodiment: The compressor impeller forging blank heat treatment oven includes a chamber body 100, a door, a heating plate 200, and a shelf 300. The chamber body 100 has an inner cavity 101, a first opening at the front end, and a second opening at the lower end. One side of the door is hinged to the front end of the chamber body 100; rotating the door opens or closes the first opening. The heating plate 200 is detachably located at the lower end of the chamber body 100; removing or installing the heating plate 200 opens or closes the second opening. The heating plate 200 contains a heating wire 201. For example, shelf slots 102 are provided on the left and right sides of the lower end of the chamber body 100, and the two ends of the heating plate 200 are mounted on the two shelf slots 102. The shelf 300 is mounted on the heating plate 200, and the shelf 300 has several partitions 301 spaced vertically, on which several forging blanks 400 are placed.

[0020] Furthermore, a first sealing and insulation layer 103 is provided on the support groove 102. The bottom ends of both sides of the heating plate 200 are mounted on the first sealing and insulation layer 103 and are in sealed contact with the first sealing and insulation layer 103. When the heating plate 200 is mounted on the support groove 102, the sealing contact between the bottom ends of the heating plate 200 and the first sealing and insulation layer 103 effectively fills and seals the assembly gap between the heating plate 200 and the support groove 102, reducing heat leakage from the bottom of the box 100 to the outside, reducing overall energy consumption, and ensuring that the thermal environment of the solution treatment process meets the process requirements.

[0021] Furthermore, support legs 104 are provided at the bottom of the left and right sides of the housing 100, a rotating base plate 302 is provided at the bottom of the shelf 300, and a motor 500 is provided at the bottom of the heating plate 200. The output end of the motor 500 passes through the heating plate 200 and is connected to the bottom of the rotating base plate 302. The motor 500 drives the rotating base plate 302 to rotate. By driving the rotating base plate 302 driven by the motor 500, the shelf 300 rotates as a whole, so that the forging billet 400 placed on the partition 301 rotates continuously during the heat treatment process. The forging billet 400 is heated evenly at all positions, avoiding local temperature differences in the forging billet 400. At the same time, the rotational motion promotes the hot airflow to penetrate the gaps in the forging billet 400, enhances the heat conduction efficiency, shortens the heating time, and improves the efficiency of solution treatment.

[0022] Furthermore, the surface of the rotating base plate 302 is provided with several holes 303. The holes 303 form airflow channels that penetrate the rotating base plate 302, allowing the hot air generated by the heating plate 200 to penetrate upwards through the base frame and diffuse evenly to the partition plate 301 area of ​​each layer of the shelf 300, so that the forging billet 400 is heated evenly and the time required for solution treatment is shortened.

[0023] Furthermore, a second sealing and heat-insulating layer 202 is provided on the left and right sides and the top of the heating plate 200. The second sealing and heat-insulating layer 202 on the left and right sides of the heating plate 200 is in sealed contact with the inner walls of the left and right sides of the bottom of the box 100. The second sealing and heat-insulating layer 202 forms a sealed contact with the inner wall of the bottom of the box 100, realizing a two-stage sealing of the assembly gap between the heating plate 200 and the box 100. This, together with the first sealing and heat-insulating layer 103, reduces the leakage of high-temperature airflow and ensures a uniform temperature distribution in the inner cavity 101 of the box 100.

[0024] Furthermore, an air duct 110 is provided on the outer side of the housing 100. The air duct 110 includes a first vertical pipe 111, a second vertical pipe 112, a first horizontal pipe 113, and a second horizontal pipe 114. The first vertical pipe 111 is located on the upper left side of the housing 100, and its lower end extends into the inner cavity 101. The right side of the first horizontal pipe 113 is connected to the top end of the first vertical pipe 111. The upper end of the second vertical pipe 112 is connected to the left side of the first horizontal pipe 113. The left side of the second horizontal pipe 114 is connected to the lower end of the second vertical pipe 112, and its right side extends into the inner cavity 101. A first fan 600 is provided on the right side of the housing 100. The output end of the first fan 600 extends into the inner cavity 101, and the output direction of the first fan 600 corresponds to that of the second horizontal pipe 114. The air duct 110, together with the first fan 600, forms a circulating airflow. The circulating airflow avoids the stratification of heat in the inner cavity 101, and allows the high-temperature gas to diffuse evenly in the vertical direction, ensuring the consistency of axial and radial heating of the forging billet 400.

[0025] Furthermore, a second fan 700 is provided at the upper end of the first vertical pipe 111, and the output end of the second fan 700 extends into the first vertical pipe 111. The second fan 700 actively pressurizes and delivers air into the first vertical pipe 111, thereby accelerating the airflow speed in the air duct 110 and improving the efficiency of the solution treatment of the forging billet 400 in the inner cavity 101.

[0026] In operation, this embodiment is as follows: First, rotate the cabinet door to close the first opening. Then, install the heating plate 200 onto the rack slot 102 at the lower end of the cabinet 100, closing the second opening and ensuring that the second sealing and insulation layers 202 on both sides of the heating plate 200 are in sealed contact with the inner wall of the cabinet 100. Start the heating wire 201 to heat the inner cavity 101. Simultaneously, drive the rotating base plate 302 via the motor 500 to rotate the shelf 300 and the forging billet 400. The holes 303 on the surface of the rotating base plate 302 promote the penetration of hot airflow. At the same time, turn on the first fan 600 to inject airflow into the inner cavity 101. 1. The air is guided to the second horizontal pipe 114, and together with the second fan 700, a circulating airflow is formed in the air duct 110. The hot air enters through the lower end of the first vertical pipe 111, and after passing through the air duct 110, it flows back to the inner cavity 101 from the end of the second horizontal pipe 114, achieving uniform heating. After the solution treatment is completed, heating and rotation are stopped, the rotating box door opens the first opening, the heating plate 200 is removed and detached from the rack slot 102, and the rack 300 is moved out from the second opening along with the heating plate 200. It can be directly transferred to the ineffective treatment equipment for further processing.

[0027] In this embodiment, the shelf 300 is directly placed on the heating plate 200, so that the heating plate 200 and the shelf 300 form a detachable module. After the solution treatment is completed, only the heating plate 200 needs to be removed to simultaneously move the entire shelf 300 module carrying the high-temperature workpiece out from under the box 100. This avoids the cumbersome operation of disassembling the shelf 300 at the first opening, reduces the exposure time and heat loss of the high-temperature workpiece during the transfer process, reduces energy consumption, shortens the process connection time, and improves the overall processing efficiency.
