The exhaust pipe 4 is fixedly connected to the top of the L-shaped tube 2, and is used to discharge the gas generated during the dewaxing process and send it to the recovery mechanism to recover the wax in the gas, thereby preventing waste of resources and preventing excessive pressure inside the equipment, thereby ensuring safe operation of the equipment.

[0038] Reference Figure 1 、 Figure 5 and Figure 6 The recovery mechanism includes a cooling box 8, with a collection net 7 slidably connected to the interior of the cooling box 8. An insert 24 is fixedly connected to the exterior of the collection net 7. A fixing block 26 is fixedly connected to the exterior of the cooling box 8. A fixing assembly is provided within the fixing block 26. The exhaust pipe 4, located at the end away from the L-shaped tube 2, is fixedly connected to the top of the cooling box 8.

The collection net 7 slidably connects to the interior of the cooling box 8 and collects the wax precipitated during the cooling process for easy recovery. The insert 24 is inserted into the fixing block 26 and, through the action of the fixing assembly, secures the collection net 7. The air outlet pipe 5 is used to discharge the cooled gas. The water supply pipe 6 is used to add cold water to the interior of the cooling box 8. The water outlet pipe 9 is used to transport the water after heat exchange to a designated location for recycling.

[0039] Reference Figure 5 and Figure 6The fixing assembly includes an outer shell 21, the outer side of the outer shell 21 is fixedly connected to the inside of the fixed block 26, the inner shell 21 is fixedly connected to the inner shell 3, the inner shell 3 is slidably connected to the inside of the inner shell 3, the outer side of the latch 25 is provided with a spring three 27, and the outer side of the latch 25 is provided with a self-locking component. The outer shell 21 is used to carry the various parts inside it to ensure normal operation. The inner shell 3 is used to provide space for the sliding of the latch 25. The latch 25 is used to be plugged into the inside of the plug block 24 to lock the collection net 7. The spring three 27 is used to prevent the latch 25 from moving when there is no external force. The self-locking assembly is used to lock the latch 25 by rotating the latch 25 when the latch 25 is pulled out of the plug block 24, without having to pull the latch 25 hard all the time.

[0040] Reference Figure 5 and Figure 6 The self-locking component includes an L-shaped rod 23 and a backing plate 28. The L-shaped rod 23 is fixedly connected to the outside of the backing plate 28. The middle of the backing plate 28 is fixedly connected to the outside of the latch 25. An L-shaped groove 22 is formed on the outside of the inner shell 3. The plug block 24 is slidably connected to the inside of the fixed block 26. The latch 25 is inserted into the plug block 24. One end of the spring 3 27 is fixedly connected to the top of the backing plate 28. The other end of the spring 3 27 abuts the inner wall of the inner shell 3. The L-shaped rod 23 is slidably connected to the inside of the L-shaped groove 22. When the latch 25 is pulled out of the plug block 24, the L-shaped rod 23 is rotated to engage the L-shaped rod 23 in the L-shaped groove 22, thereby locking the latch 25. This eliminates the need to constantly pull on the latch 25, making it easier to remove and install the collection net 7.

[0041] Working principle: When the dewaxing kettle starts working, the kettle is heated by electric heating elements to generate high-temperature steam to achieve the dissolution and removal of wax. After the wax is melted by the high-temperature steam, part of it adheres to the inner wall of the dewaxing kettle body 1. At this time, the cleaning mechanism is started to clean the inner wall. The motor 13 in the cleaning mechanism drives the rotating shaft 12 to rotate, driving the hollow shell 11 fixedly connected to the rotating shaft 12 to rotate. At the same time, the scraper 19 is tightly attached to the inner wall of the dewaxing kettle body 1 under the constraint of the limit plate 20, and the wax attached to the inner wall is scraped off by the rotational motion. During the cleaning process, the electric push rod 17 pushes the push plate 10 to move, pushing the scraped wax to the outside of the dewaxing kettle body 1, which is convenient for the staff to collect and process it in a centralized manner. Spring 2 18 provides elastic support to ensure that the limit plate 20 and the scraper 19 always fit the inner wall of the kettle, thereby improving the cleaning effect.

[0042] During the dewaxing process, steam and waxy gases are introduced into the automatic exhaust mechanism through the L-shaped tube 2. As the air pressure in the kettle increases, the piston 14 in the L-shaped tube 2 moves under the action of pressure, compressing the spring 16, opening the outlet of the exhaust pipe 4, releasing excess steam and waxy gases, and ensuring that the air pressure inside the equipment remains stable. The exhausted steam and waxy gases enter the cooling box 8 of the recovery mechanism and are cooled by cooling water injected through the water pipe 6. The precipitated solid or liquid wax is intercepted by the collection net 7 for subsequent recovery. The cooled gas is discharged through the outlet pipe 5, and the wastewater generated during the cooling process is discharged through the outlet pipe 9 and can be recycled.

[0043] In the recycling mechanism, the collection net 7 is secured by a fixing assembly. This assembly consists of a fixing block 26, a latch 25, and a spring 27. The latch 25 is locked into the insert block 24 by the action of the spring 27, thereby securing the collection net 7. To remove the collection net 7, the latch 25 is pulled out and rotated so that the L-shaped rod 23 engages the L-shaped slot 22. The self-locking feature locks the latch 25, allowing the worker to remove the collection net 7 without applying force. After the collection net 7 is removed, the collected wax can be centrally processed and then reinstalled into the fixing block 26 after cleaning, ensuring the subsequent operation of the equipment.

[0044] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
