Description

Technical fields:

[0001] This utility model belongs to the field of welding furnace production technology, and specifically relates to a welding furnace welding oil recovery device. Background technology:

[0002] In semiconductor packaging processes, soldering furnaces are used to solder products. During the soldering process, solder oil gradually accumulates inside the soldering furnace. If it is not cleaned in time, it will affect the normal operation of the soldering furnace.

[0003] The traditional method involves using fume extraction equipment to vent the welding grease from the furnace into the outside atmosphere. While this solves the problem of welding grease buildup inside the furnace, the resulting fumes pollute the external atmosphere. Furthermore, the large amount of welding grease released with the fumes also leads to waste and increases production costs.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility model content:

[0005] The purpose of this invention is to provide a welding furnace welding oil recovery device, thereby overcoming the defects in the prior art.

[0006] To achieve the above objectives, this utility model provides a welding furnace welding oil recovery device, including a housing, an exhaust fan, a high-voltage ionization mechanism, an oil collection tank, an air inlet, and an exhaust outlet. The housing contains the exhaust fan, the high-voltage ionization mechanism, and the oil collection tank. An air inlet and an exhaust outlet are located on one side of the housing. The high-voltage ionization mechanism is fixed within the housing. The air inlet is connected to the high-voltage ionization mechanism. The air inlet of the exhaust fan is connected to the high-voltage ionization mechanism, and the exhaust outlet of the exhaust fan is connected to the exhaust outlet. An airflow channel is formed by the air inlet, the high-voltage ionization mechanism, the exhaust fan, and the exhaust outlet. The high-voltage ionization mechanism includes an ionization tank. The system consists of a body, an electrode mechanism, and an ionization tank fixed within a box. The ionization tank contains an electrode mechanism, an air inlet connected to it, a bottom connection to an oil collection tank, and a top connection to an exhaust fan via a pipe. The electrode mechanism is connected to an external power source. A gas rising channel is formed between the electrode mechanism and the inner wall of the ionization tank. Gas enters the ionization tank through the air inlet and rises along a spiral path within the channel. A high-voltage electric field is generated within the ionization tank through the electrode mechanism. After ionization, negatively charged welding oil particles are adsorbed onto the anode of the electrode mechanism and fall into the oil collection tank under gravity.

[0007] Preferably, in the technical solution, the high-voltage ionization mechanism includes an ionization tank, an anode electrode rod, a cathode electrode, a sealing cover, and a gas outlet. The ionization tank has an opening at both the top and bottom. The lower opening of the ionization tank is connected to an oil collection tank. A sealing cover is provided at the top opening of the ionization tank. The sealing cover is provided with an anode electrode rod, a cathode electrode, and a gas outlet. The anode electrode rod and cathode electrode form an electrode mechanism. The anode electrode rod and cathode electrode extend into the inner cavity of the ionization tank. The anode electrode rod and cathode electrode are connected to an external power source. The gas outlet is connected to the air inlet of a blower through a pipeline.

[0008] Preferably, in the technical solution, the anode electrode rod is provided with branch electrodes on the upper surface. The branch electrodes are inclined downward and located in the gas rising channel, which increases the contact area between the anode electrode rod and the welding oil particles and accelerates the welding oil recovery efficiency.

[0009] Preferably, in the technical solution, a base is provided inside the ionization tank, an anode electrode rod is placed on the base, an air outlet is provided on the side of the base, the air outlet is set at 90° with the air inlet, and the air outlet is connected to the gas rising channel through the air outlet.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] By using high-voltage ionization to adsorb and recover welding oil particles in the exhaust gas, the pollution of the exhaust gas to the external environment is reduced, welding oil waste is reduced, and production costs are lowered. Attached image description:

[0016] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0017] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "comprises" shall be understood to include the stated elements or components without excluding other elements or other components.

[0018] like Figure 1-3 As shown, a welding furnace welding oil recovery device includes a housing 1, an exhaust fan 2, a high-voltage ionization mechanism 3, an oil collection tank 4, an air inlet 5, and an exhaust outlet 6; the housing 1 is equipped with the exhaust fan 2, the high-voltage ionization mechanism 3, and the oil collection tank 4, and one side of the housing 1 is provided with the air inlet 5 and the exhaust outlet 6, and the exhaust end of the exhaust fan 2 is connected to the exhaust outlet 6;

[0019] The high-voltage ionization mechanism 3 includes an ionization tank 30, an anode electrode rod 31, a cathode electrode 32, a sealing cover 33, a gas outlet 34, a base 35, and branch electrodes 36. A support 7 is installed inside the housing 1, and the ionization tank 30 is fixedly mounted on the support 7. The ionization tank 30 has an opening at both the top and bottom. The lower opening of the ionization tank 30 is connected to the oil collection tank 4, and a sealing cover 33 is installed at the top opening of the ionization tank 30. A base 35 is installed inside the ionization tank 30 and is connected to the sealing cover 33. The anode electrode rod 31 is mounted on the base 35, and the cathode electrode 32 and gas outlet 34 are mounted on the sealing cover 33. The anode electrode rod 31 and cathode electrode 32 form an electrode mechanism, extending into the inner cavity 30 of the ionization tank. The cathode electrode 32 is connected to an external power source. The area between the electrode mechanism and the inner wall of the ionization tank 30 forms a gas rising channel. Gas enters the ionization tank 30 through the inlet 5 and rises along a spiral path in the gas rising channel. An outlet 37 is provided on the side of the base 35. The outlet 37 is set at 90° with the inlet 5. The outlet 34 is connected to the gas rising channel through the outlet 37. The outlet 34 is connected to the inlet of the exhaust fan 2 through a pipeline. The inlet-gas rising channel-outlet-outlet-exhaust fan-exhaust port form an airflow channel. The anode electrode rod 31 is surrounded by branch electrodes 36. The branch electrodes 36 are set downward and are located in the gas rising channel, which increases the contact area between the anode electrode rod 31 and the welding oil particles and accelerates the welding oil recovery efficiency.

[0020] In operation, an external power supply is turned on, creating a high-voltage electric field between the anode electrode rod 31 and the cathode electrode 32. The exhaust fan 2 is then turned on, and air from the welding furnace enters the ionization tank 30 through the air inlet 5. In the rising gas channel, the air is discharged by the cathode electrode 32, ionizing the gas molecules into positive and negative ions. These ions come into contact with welding oil particles, causing the particles to acquire a negative charge. These negatively charged particles adhere to the anode electrode rod 31 and the branch electrode 36. Under gravity, these welding oil particles fall to the bottom of the ionization tank 30 and are collected by the oil collection tank 4. The adsorbed air then passes through the air outlet 37, the air outlet 34, and the exhaust end of the exhaust fan 2, finally being discharged through the exhaust port 6. This welding oil recovery device reduces pollution of the external environment from the exhaust gas, minimizes welding oil waste, and lowers production costs.
