Specifically, the common degreasing furnace airflow circulation system in the prior art has the following problems: 1. The airflow of traditional degreasing furnaces usually relies on a simple air duct design. The airflow is not uniform, which easily leads to strong airflow in some areas of the furnace cavity and weak airflow in other areas. This not only affects the effect of the degreasing process, but also may cause insufficient heating of the degreased products in some areas, resulting in incomplete or uneven degreasing.

[0003] 2. In the existing degreasing furnace, the heat distribution is often concentrated during the airflow process, and the temperature of each part in the furnace cavity cannot be balanced, which leads to uneven heating of some products to be degreased. Excessive temperature difference will make the surface grease of some products not completely removed, affecting the overall degreasing effect.

[0020] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0021] like Figure 1 to Figure 13 As shown, the degreasing furnace of this embodiment includes a furnace body 10, an airflow circulation component, a heating component and a condensing device 50.

[0022] A furnace cavity 11 for placing products to be degreased is provided in the furnace body 10, and an opening communicating with the furnace cavity 11 is provided on the front side of the furnace body. A furnace door 15 is movably provided on the opening to open and close the opening. When the opening is opened, the products to be degreased can be placed into the furnace cavity 11 through the opening, and the furnace door 15 can close the opening to degrease the products in the furnace cavity 11.

[0023] There are two airflow circulation components, and the two airflow circulation components are arranged adjacent to each other along the front-to-back direction of the furnace body 10 .

[0024] Each airflow circulation component includes two air ducts 20 and a first fan 30. The two air ducts 20 are respectively located on the left and right sides of the furnace cavity 11 and are arranged opposite to each other. The two air ducts 20 are respectively attached to the left and right inner walls of the furnace body 10. The first wind wheel 31 of the first fan 30 is located above the furnace cavity 11. The first motor 32 of the first fan 30 is located at the top of the furnace body 10. The first motor 32 drives the first wind wheel 31 to rotate through a belt drive. When the first wind wheel 31 rotates, it can suck the gas in the furnace cavity 11 out of the top of the furnace cavity 11, and then blow the gas from the left and right sides of the furnace cavity 11 into the furnace cavity 11 through the two air ducts 20 to form a circulating airflow. The two air ducts 20 are vertically arranged on one surface facing the furnace cavity 11, and a plurality of air outlet components 21 arranged in an array are arranged on one surface of the two air ducts 20 facing the furnace cavity 11, wherein the array has a horizontal axis extending along the front-to-back direction of the furnace body 10 and a longitudinal axis extending along the up-down direction of the furnace body 10, and each air outlet component 21 includes two first air outlet pipes 211 and two second air outlet pipes 212, and the two first air outlet pipes 211 are arranged at intervals along the horizontal axis direction of the array, and the air outlets of the two first air outlet pipes 211 are respectively inclined toward the up-down direction of the furnace cavity 11, and the two second air outlet pipes 212 are arranged at intervals along the longitudinal axis direction of the array, and the two second air outlet pipes 212 are arranged at intervals along the longitudinal axis direction of the array. The air outlets of the two air ducts 20 are respectively arranged in an inclined manner toward the front and rear directions of the furnace cavity 11, and a plurality of third air outlet pipes 22 are arranged at the bottom of the two air ducts 20. The plurality of third air outlet pipes 22 are arranged at intervals along the horizontal axis direction of the array, and the air outlets of the plurality of third air outlet pipes 22 are all located at the bottom of the furnace cavity 11. In this way, the air duct 20 can blow air into the furnace cavity 11 through the air outlet components 21 and the third air outlet pipes 22. Since the air outlet components 21 are arranged in an array, and the air outlets of the two first air outlet pipes 211 in the air outlet components 21 are respectively arranged in an inclined manner toward the upper and lower directions of the furnace cavity 11, and the air outlets of the two second air outlet pipes 212 are respectively arranged toward the upper and lower directions of the furnace cavity 11, so that the air duct 20 passes through the air outlet components When 21 blows air into the furnace cavity 11, the airflows of the air outlet components 21 arranged in an array can be mixed with each other, so that the air outlet components 21 can blow air into the furnace cavity 11 more evenly and smoothly, and the air duct 20 can also blow air to the bottom of the furnace cavity 11 through the third air outlet pipe 22, and then the air flow rises along the furnace cavity 11, so that the air flow in the furnace cavity 11 can penetrate the furnace cavity 11 and fully contact the surface of the product, and at the same time the heating component can heat the airflow flowing through the two air ducts 20, so that the product to be degreased in the furnace cavity 11 can be heated more evenly, so that the temperature of each part of the product to be degreased is more consistent, so that the degreasing effect is better.

[0025] The condensing device 50 is used to suck out the gas after circulating heating in the furnace cavity 11, cool the gas to remove grease in the gas, and then send the gas back to the furnace cavity 11. In this way, after the heated air flow in the furnace cavity 11 circulates for a certain period of time, the grease on the product has been taken away by the hot air. At this time, the condensing device 50 is turned on. The condensing device 50 can suck out the hot air in the furnace cavity 11 for condensation, so that the grease carried in the hot air condenses on the condenser tube, thereby removing the grease in the hot air.

[0026] Reference Figure 5 , Figure 6 The air duct 20 is provided with a plurality of vertically arranged partitions 23, and the partitions 23 are used to divide the space in the air duct 20 into a plurality of air flow channels 25, and the air flow channels 25 are vertically arranged up and down, and a third air outlet pipe 22 is arranged at the bottom of each air flow channel 25, and each air flow channel 25 is connected with three columns of air flow components 21, and a column of air flow components refers to a plurality of air outlet components arranged vertically up and down, and a plurality of guide plates 24 are arranged in each air flow channel 25, and a guide plate 24 is arranged between any two adjacent columns of air flow components 21, and the guide plates 24 are arranged vertically to guide each air flow. The airflow in the channel 25 flows vertically downward, so that the airflow in each airflow channel 25 is guided to flow vertically downward, which can ensure that the airflow in the furnace chamber 11 is evenly distributed and avoid uneven heat or uneven heating of the product caused by the airflow being concentrated in certain areas; and the configuration of multiple vertical airflow channels 25 and three columns of air flow components 21 enables each column of air flow components 21 to generate airflow and disperse it in multiple directions, and guide plates 24 are arranged between each column of air flow components. The vertical setting of the guide plates helps the airflow to flow more orderly and avoids disorderly airflow, thereby enhancing the overall airflow control ability.

[0027] Reference Figure 6A hood 12 is provided above the furnace cavity 11, and the hood 12 encloses a chamber, and the hood 12 has openings on both sides, and the two sides of the hood 12 are respectively connected with the upper ends of the two air ducts 20, so that the chamber inside the hood 12 is connected with the air ducts 20 through the openings, and a first wind wheel 31 is provided in the hood 12, and the lower end surface of the first wind wheel 31 is an air inlet, and the air inlet of the first wind wheel 31 is connected with the furnace cavity 11, and the entire outer circumferential surface of the first wind wheel 31 is an air outlet surface. When the first wind wheel 31 rotates, the gas in the furnace cavity 11 is sucked out and then the gas is blown into the two air ducts 20 through the two sides of the hood 12 at the same time, and then the air flow flows downward along the hood 20, and the air flow returns to the furnace cavity 11 through the air outlet assembly 21 and the third air outlet pipe 22. A plurality of air outlets are provided on both sides of the hood 12 along The air guide plates 14 are arranged at intervals in the circumferential direction of the first wind wheel 31, and one end of each air guide plate 14 is close to the outer circumferential surface of the first wind wheel 31, and the other end of each air guide plate 14 is located at the air inlet of the air duct 20. In this way, through the action of the wind hood 12, the gas can flow smoothly from the furnace chamber 11 to the air duct 20, which effectively improves the circulation efficiency of the gas. The gas suction and air supply process is continuous, which reduces the residence time of the air flow, thereby improving the air flow exchange efficiency during the degreasing process, and the air guide plate 14 can effectively distribute the gas in the wind hood evenly to the entrance of the air duct 20. The function of the air guide plate is to control the direction of the air flow and reduce the air flow deviation, so as to ensure that the air flow can be more evenly distributed after entering the air duct, prevent the local air flow from being too strong or too weak, and ensure uniform heating of the product in the furnace chamber.

[0028] The heating assembly includes a plurality of electric heating rods 40, and the plurality of electric heating rods 40 are divided into two rows on the left and right sides. 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 pluggable and plugged into the top of the furnace body 10. The heating parts of the plurality of electric heating rods 40 are all extended into the air duct 20, so that there are two heating parts of the electric heating rods 40 in the air flow channel 25 of each air duct 20. The electrical connection parts of the plurality of electric heating rods 40 are all located on the upper surface of the top of the furnace body 10. This design can make the air ducts 20 on the left and right sides of the furnace cavity 11 be evenly heated, ensuring that the air flow channel 25 in the air duct 20 obtains a consistent heating effect, and because each air flow channel 25 has two heating parts, The heating part of the electric heating rod 40 is a heat generating part, so that even the airflow on both sides of the furnace chamber 11 can obtain uniform heat distribution, thereby ensuring uniform heating during the degreasing process, avoiding overheating or insufficient heating in certain areas, and improving the overall heating effect; and the electric heating rod 40 is a pluggable design, which is not only convenient for installation and maintenance, but also improves the flexibility of the system. When a fault occurs or the electric heating rod 40 needs to be replaced, the user can easily replace the faulty electric heating rod 40 without replacing the entire heating system. The pluggable design also makes the number and configuration of the electric heating rods 40 more flexible, which is convenient for adjusting the heating capacity or replacing the electric heating rods 40 according to actual needs, further improving the adaptability and service life of the equipment.
