Description

Technical Field

[0001] The present application belongs to the field of heat treatment technology, and specifically relates to a temperature-controlled heat treatment furnace. Background Art

[0002] The heat treatment furnace uses thermocouple temperature control, which can accurately feedback the temperature in the furnace. The temperature in the furnace can be adjusted through equipment instruments and thermocouples, but the location of the thermocouple temperature measuring end plays a vital role in the feedback and accurate measurement of the temperature in the furnace. The traditional heat treatment furnace will lose a lot of heat in the furnace when taking out the finished product, thereby increasing the energy consumed by the subsequent heat treatment temperature increase. Therefore, we made improvements to this and proposed a heat treatment furnace temperature control structure.

[0003] For example, the patent CN214120809U provides a temperature control structure for a heat treatment furnace, in which a base is fixed at the bottom of the shell, a lifting frame is fixed in the middle of the shell, a pneumatic cylinder is fixed in the middle of the top of the lifting frame, a slide is fixed in the middle of the lifting frame, the middle of the lifting frame is slidably connected to a heat insulation board, a telescopic rod is fixed at the bottom of the pneumatic cylinder, the bottom of the telescopic rod is fixedly connected to the middle of the top of the heat insulation board, a door is connected to one side of the transport cabin through a hinge, and a main control panel is fixed on one side of the heat treatment cabin. However, the door of the transport cabin in the above patent still has a lot of heat discharge when it is opened, and the temperature control effect is not enough. Utility Model Content

[0017] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0018] See also Figure 1-3 A temperature-controlled heat treatment furnace comprises a heating chamber 1 and a transport chamber 2; a first conveyor belt 11 is provided in the heating chamber 1 and an opening door 12 is provided at the inlet end; a second conveyor belt 21 is provided in the transport chamber 2 and an outlet door 22 is provided at the outlet end; the transport chamber 2 is located at the lower side of the heating chamber 1, and the lower part of the outlet end of the heating chamber 1 is connected to the upper part of the inlet end of the transport chamber 2; wherein, a lifting platform 3 which can rise to the heating chamber 1 is provided at the inlet end of the transport chamber 2. The heating chamber 1 in the above-mentioned design is arranged above the transport chamber 2, which effectively retains the hot air in the heating chamber 1 and reduces the heat loss.

[0019] The lifting platform 3 includes a first cylinder 31 and a roller platform 32. The first cylinder 31 is arranged at the side end of the second conveyor belt 21. The lower middle part of the roller platform 32 is connected to the telescopic rod of the first cylinder 31. The lifting platform 3 in the above design can transport the heat-treated parts in the heating chamber 1 to the transport chamber 2.

[0020] A plurality of parallel rollers 33 are provided on the upper surface of the roller table 32. The rollers 33 in the above design can reduce friction and facilitate the movement of the heat-treated parts on the surface of the roller table 32.

[0021] The maximum lifting height of the roller table 32 is flush with the first conveyor belt 11; the minimum lifting height of the roller table 32 is flush with the second conveyor belt 21. When the roller table 32 in the above design is flush with the first conveyor belt 11, the first conveyor belt 11 conveys the heat-treated parts into the roller table 32 by inertia; when the roller table 32 is flush with the second conveyor belt 21, it is convenient for the heat-treated parts to enter the second conveyor belt 21.

[0022] A push plate 4 is provided on the side wall of the transport cabin 2 near the lifting platform 3, and the push plate 4 is connected to the telescopic rod of the second cylinder 41 fixed to the side wall of the transport cabin 2, wherein the bottom height of the push plate 4 is greater than the surface height of the second conveyor belt 21. In the above design, the push plate 4 can push the parts on the roller table 32 into the second conveyor belt 21.

[0023] The outer wall of the heating chamber 1 is provided with a heating inlet pipe 51 and a heating inlet and outlet pipe 52, both of which are connected to the heating pipe 5 in the heating chamber 1; wherein a temperature sensor 52 is provided inside the heating chamber 1. The heating inlet pipe 51 and the heating inlet and outlet pipe 52 can be connected to an external heating medium (such as hot kerosene and hot water, etc.) to heat the heating chamber 1, and control the flow rate of the heating medium according to the temperature displayed by the temperature sensor.

[0024] A circulating fan 6 is disposed on the top of the heating chamber 1. The circulating fan 6 designed as above can make the hot air in the heating chamber 1 flow evenly, thereby ensuring that the temperature in the heating chamber 1 is relatively uniform and improving the heat treatment effect.

[0025] An air outlet pipe 7 is provided at the upper end of the heating chamber 1, and a pneumatic valve 71 is provided in the air outlet pipe 7 for controlling the opening and closing of the air outlet pipe 7. When the air outlet pipe 7 in the above design is opened, the heating chamber 1 can be cooled down quickly.

[0026] The specific working method is to open the opening hatch 12, feed the parts to be heat treated into the first conveyor belt 11, close the hatch, then open the heating pipe 5 to heat the heating chamber 1 and turn on the circulating fan 6. After the heat treatment is completed, the roller table 32 rises to the same level as the first conveyor belt 11, and the first conveyor belt 11 feeds the heat-treated parts into the roller table 32 by inertia, and then descends to the same level as the second conveyor belt 21, and the push plate 4 is started to push the heat-treated parts into the second conveyor belt 21, and then the exit hatch 22 is opened to take out the heat-treated parts.

[0027] The present application disposes the transport cabin 2 below the heating cabin 1. Since the hot air will flow upward, most of the heat in the heating cabin 1 will remain in the upper heating cabin 1, thereby reducing the heat loss when the transport cabin 2 is opened. Moreover, when not in use, the lifting platform 3 can be set at the connection between the heating cabin 1 and the transport cabin 2 to further prevent heat loss.

[0028] The above description is only an embodiment of the present application and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present application.
