Technical Field

[0001] This utility model relates to the field of heat treatment heating furnace technology, and in particular to a furnace cover for a well-type rotary arm heat treatment heating furnace. Background Technology

[0002] The furnace cover device of a pit-type heating furnace is crucial, as it directly affects the temperature uniformity, overall energy consumption, and service life of the equipment. Currently, the furnace cover lifting of pit-type heating furnaces generally adopts a double-beam translation trolley, which has the disadvantages of complex structure, high investment cost, and large footprint. Alternatively, existing lifting equipment (overhead crane) in the workshop can be used to open the furnace cover, but this method is inconvenient to operate and can easily lead to furnace cover deformation.

[0003] The well-type rotary arm heat treatment furnace with its furnace cover still has the following drawbacks: when loading materials, the lifting equipment needs to be opened and closed, which wastes a lot of time and the physical strength of the staff. Furthermore, when the pressure inside the furnace is too high, it cannot be released. When loading materials later, the furnace needs to be fully opened, which results in rapid temperature loss and requires reheating, leading to serious waste of resources. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a matching furnace cover for a well-type rotary arm heat treatment furnace.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a well-type rotary arm heat treatment heating furnace with a matching furnace cover, applied to the heating furnace.

Then, cylinder 29 can be opened to make slide plate 10 slide in slide groove 11. This is suitable for heating materials in well-type rotary arm heat treatment, where only a part needs to be opened, reducing the heat loss in furnace 1. In addition, a cylinder 15 is provided on furnace cover 7. When the pressure in furnace 1 is too high, the pressure pushes up slider 16 and fixed block 18, releasing the pressure from exhaust hole 17 to reduce the pressure. When the pressure is released, slider 16 drives fixed block 18 to fall, and fixed block 18 blocks exhaust hole 17. This is suitable for adjusting the pressure in furnace 1.

[0025] A fixing plate 19 is fixedly connected to the fixing frame 25. A fixing plate 20 is rotatably connected to the cylinder 29. A frame 21 is rotatably connected to the fixing plate 20. The frame 21 has a sliding groove 24. A slider 23 is slidably connected to the sliding groove 24. A spring 22 is fixedly connected to one end of the slider 23. One end of the spring 22 is fixedly connected to the frame 21. One end of the slider 23 is attached to the cylinder 29. A cylinder 15 is fixedly connected to the furnace cover 7. A slider 16 is slidably connected inside the cylinder 15. A fixing block 18 is fixedly connected to one end of the slider 16. An exhaust hole 17 is provided inside the cylinder 15. One end of the exhaust hole 17 is attached to the fixing block 18. An observation hole 25 is fixedly connected to the furnace cover 7. A sliding plate 26 is slidably connected to the observation hole 25. A handle 27 is fixedly connected to one side of the sliding plate 26. The observation hole 25 and the sliding plate 26 are fixedly connected by bolts 28. The observation hole 25 passes through the furnace cover 7. The shape of the slider 23 is... The cylinder 29 is circular with a groove. A second slider 23 passes through the frame 21 and is housed within the spring 22. Two sets of exhaust holes 17 pass through the cylinder 15. A first slider 16 passes through the cylinder 15, which in turn passes through the furnace cover 7. The furnace cover 7 is hemispherical, and the second furnace cover 13 is circular. When fully opened, the cylinder 3 is activated, causing the furnace cover 7 on the fixed plate 4 to rotate and rise. The furnace cover 7 is designed for easy opening and closing. A cylinder 29 is provided on one side of the furnace cover 7. By moving the fixing plate 3 20, the fixing plate 3 20 drives the slider 23 on the frame 21 to fix the cylinder 29 on the furnace cover 7. This is suitable for fixing the furnace cover of the well-type rotary arm heat treatment heating furnace 1. The furnace cover 7 is provided with an observation hole 25. A sliding plate 26 is provided on the observation hole 25. The sliding plate 26 is pulled by the handle 27, which is suitable for observing the heating status of the materials in the heating furnace 1.

[0026] Working principle: When materials need to be heated in the well-type rotary arm heat treatment furnace 1, the operator first pulls the fixed plate 3 20 upward. The fixed plate 3 20, through the action of the fixed plate 2 19 on the fixed frame 2 5, drives the frame 21 to rise. The frame 21, through the action of the spring 22, drives the slider 2 23 to slide and rise on the slide groove 24, so that one end of the slider 2 23 disengages from the cylinder 29 on the furnace cover 7, thereby releasing the furnace cover 7 from fixation. Then, the cylinder 3 is opened, and the cylinder 3 drives the fixed plate 4 to move downward. The fixed plate 4, through the bracket 6 on the fixed frame 2 5, drives the furnace cover 7 to rise and open, thus facilitating the loading of materials. After the material is added, cylinder 3 is turned off. Next, one end of slider 23 is placed on cylinder 29. Then, fixing plate 3 20 is pulled down. Fixing plate 3 20 moves frame 21 downwards, which in turn moves slider 23 downwards. Under the action of spring 22, one end of slider 23 is locked onto cylinder 29, thus securing furnace cover 7. During heating, when additional material is needed, cylinder 3 12 is turned on, causing furnace cover 2 13 to rise. When furnace cover 2 13 detaches from furnace cover 7, cylinder 3 12 is turned off, and cylinder 2 9 is turned on. Cylinder 2 9 moves slide plate 10 into the groove 11 on bracket 2 14. The sliding plate 10 synchronously moves the furnace cover 13. When the furnace cover 13 moves to one side, the added material can be put in. This is suitable for use in heating furnace 1. When heating, the furnace cover 10 can be opened to put in the material, reducing heat loss in heating furnace 1 and thus reducing the resources needed to raise the temperature in heating furnace 1. The furnace cover 7 is equipped with a cylinder 15. When the pressure in heating furnace 1 is too high, the pressure pushes the slider 16 upward within the cylinder 15. The slider 16 simultaneously moves the fixed block 18 upward. When the slider 16 rises to a certain height, the pressure is released outward through the vent 17 inside the cylinder 15. As the pressure gradually decreases, slider 16 drives fixed block 18 to slowly descend until it returns to its original position. Thus, the lower ends of fixed block 18 and slider 16 block both ends of exhaust hole 17, which is suitable for adjusting the pressure inside heating furnace 1. When it is necessary to observe the material inside heating furnace 1 during the heating process, first loosen bolt 28, and then move handle 27 outward. Handle 27 drives slide plate 26 outward in observation hole 25. When it slides out to the desired position, it can be viewed, which is convenient for observing the inside of heating furnace 1 during the heating process. After observation, push slide plate 26 inward with handle 27 to close it, and then tighten bolt 28 downward.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
