Description

TECHNICAL FIELD

[0002] The degreasing furnace is a device for removing oil on the surface of products to be processed, widely used in metal processing, machinery manufacturing and other industries. With the continuous development of industrial production, the degreasing technology is also constantly improving, but the existing degreasing furnace still has certain limitations in air flow distribution and heating uniformity. Specifically, the air flow circulation system of the degreasing furnace commonly seen in the prior art has the following problems:

[0003] 1. The air flow of the traditional degreasing furnace usually depends on a simple air duct design, and the air flow is not uniform enough, which can easily lead to stronger air flow in some areas of the furnace cavity and weaker air flow in other areas. This not only affects the effect of the degreasing process, but also can cause some areas of the product to be degreased to be insufficiently heated, resulting in incomplete or uneven degreasing.

[0004] 2. In the existing degreasing furnace, the heat distribution during air flow is often concentrated, and the temperature of each part of the furnace cavity cannot be balanced, which can further lead to uneven heating of some products to be degreased. The excessive temperature difference can cause incomplete removal of oil on the surface of some products, affecting the overall degreasing effect.

[0005] 3. Due to the uneven air flow and uneven heating, the existing equipment may need higher energy input to ensure the degreasing effect, increasing the operating cost. In addition, the local high temperature area can also cause energy waste.

[0051] The condensing device 50 is used to draw out the gas that has been circulated and heated in the furnace chamber 11 and cool the gas to remove the grease in the gas. Then the gas is sent back to the furnace chamber 11. In this way, after the heated airflow circulates in the furnace chamber 11 for a certain period of time, the grease on the product has been carried away by the hot air. At this time, the condensing device 50 is turned on. The condensing device 50 can draw out the hot air in the furnace chamber 11 and condense it, so that the grease carried in the hot air condenses on the condenser tube, thereby removing the grease in the hot air.

[0052] Reference Figure 5 , Figure 6 The air duct 20 is provided with multiple vertically arranged baffles 23, which divide the space within the air duct 20 into multiple airflow channels 25. Each airflow channel 25 is vertically arranged, and each airflow channel 25 has a third air outlet duct 22 at its bottom.

Each airflow channel 25 is provided with multiple guide plates 24, and a guide plate 24 is provided between any two adjacent rows of air outlet components 21. The guide plates 24 are all vertically arranged to guide each airflow. The airflow in the channel 25 flows vertically downwards. This ensures that the airflow in each airflow channel 25 is guided to flow vertically downwards, which can ensure that the airflow distribution in the furnace cavity 11 is uniform and avoid uneven heat distribution or uneven product heating caused by the airflow being concentrated in certain areas. Moreover, the configuration of multiple vertical airflow channels 25 and three rows of airflow components 21 allows each row of airflow components 21 to generate airflow and disperse it in multiple directions. The guide plates 24 are set between each row of airflow components. The vertical setting of the guide plates helps the airflow to flow more orderly and avoids the airflow being chaotic, thereby enhancing the overall airflow control capability.

[0054] The heating assembly includes a plurality of electric heating rods 40, which are divided into left and right rows, and the left and right rows of electric heating rods 40 heat the air ducts 20 on the left and right sides of the furnace cavity 11 respectively. The plurality of electric heating rods 40 are plug-in connected at the top of the furnace body 10, the heating parts of the plurality of electric heating rods 40 extend into the air ducts 20, so that each air duct 20 has two heating parts of electric heating rods 40 in the airflow channel 25, and the electric connection parts of the plurality of electric heating rods 40 are located on the upper surface of the top of the furnace body 10. This design can uniformly heat the air ducts 20 on the left and right sides of the furnace cavity 11, ensure that the airflow channels 25 in the air ducts 20 obtain consistent heating effect, and because each airflow channel 25 has two heating parts of electric heating rods 40, the airflow on both sides of the furnace cavity 11 can also be uniformly distributed, thereby ensuring uniform heating during the degreasing process, avoiding overheating or insufficient heating in some areas, and improving the overall heating effect. Moreover, the electric heating rods 40 are designed to be plug-in, which not only facilitates installation and maintenance, but also improves the flexibility of the system. When a fault occurs or the electric heating rods 40 need to be replaced, users can easily replace the faulty electric heating rods 40 without replacing the entire heating system. The plug-in design also makes the number and configuration of electric heating rods 40 more flexible, allowing for adjustment of heating capacity or replacement of electric heating rods 40 according to actual needs, further improving the adaptability and service life of the equipment.

The first transmission wheel 591 is fixedly sleeved on one of the connecting columns, and the second transmission wheel 592 is fixedly sleeved on the valve rod of one of the on-off valves 54. The transmission belt 593 is sleeved on the first transmission wheel 591 and the second transmission wheel 592, respectively, and is used to drive the first transmission wheel 591 and the second transmission wheel 592 to rotate synchronously. Since the driving motor drives the valve core of the on-off valve 54 to rotate through the valve rod, when the valve rod of the on-off valve 54 rotates, the valve rod can in turn drive the pressing plate 59 to rotate through the second transmission wheel 592, the transmission belt 593 and the first transmission wheel 591.

[0059] The filter assembly 56 and the plurality of condensing assemblies 57 are located on the front wall of the shell 51, and the second plate body 595 is used to limit the filter assembly 56 and the plurality of condensing assemblies 57 in the shell 51.

[0060] When the on-off valves 54 on the air inlet pipe 52 and the air outlet pipe 53 are closed, the second plate body 595 is separated from the front wall of the shell 51, and the second plate body 595 is parallel to the side wall of the shell 51. At this time, the filter assembly 56 and the plurality of condensing assemblies 57 can be pulled out from the front wall of the shell 51.

[0061] When the on-off valves 54 on the air inlet pipe 52 and the air outlet pipe 53 are opened, the second transmission wheel 592 rotates 90 degrees synchronously with the valve rod of the on-off valve 54, so that the second transmission wheel 592 drives the first transmission wheel 591 to rotate synchronously through the transmission belt 593, thereby driving the pressing plate 59 to rotate synchronously, so that the pressing plate 59 rotates 90 degrees, so that the second plate body 595 is pressed tightly to the front wall of the shell 51. At this time, the second plate body 595 presses the first face plate 561 of the filter assembly 56 and the second face plate 571 of the condensing assembly 57 tightly on the front wall of the shell 51, so as to limit the filter assembly 56 and the condensing assembly 57. When the condensing device 50 works, the filter assembly 56 and the condensing assembly 57 are fixed and stable, and the filter assembly 56 and the condensing assembly 57 cannot be pulled out from the shell 51, so as to avoid misoperation. The design further improves the safety and reliability of the equipment through the automatic limiting mechanism.

[0062] The specification and drawings are to be regarded in all respects as only illustrative and are to be construed in accordance with the scope of the application. It is evident that those skilled in the art can, without departing from the scope of the application, make various changes and modifications of the application. Thus, the application is intended to embrace all such changes and modifications insofar as they come within the scope of the application and its equivalents.
