Description

Technical Field

[0001] The utility model relates to the technical field of fume recovery equipment, in particular to a precious metal welding fume recovery device. Background Art

[0002] With the development of economy and the improvement of people's living standard, people's consumption of jewelry is becoming another hot spot after housing and automobiles, especially the demand for gold, which is increasing sharply. Most of gold jewelry is processed by mechanical equipment, and then inspected and polished by hand. Since gold jewelry is relatively small and has a low melting point, it can be quickly bonded by laser welding. The instantaneous temperature of laser welding rises sharply, which will produce a lot of smoke and will also be mixed with some fine gold powder. In order to ensure the safety of operators, timely ventilation is required at this time. If the smoke is discharged directly, a certain amount of precious metal will be wasted.

[0003] In the prior art, there is a patent document with publication number CN207546027U, entitled A Precious Metal Smoke Recovery Device. In this document, a filtering device is arranged in the shell to achieve a better recovery effect on high-temperature precious metal gas. The filtering device is relatively complex and is suitable for high-temperature gas during or just after processing. For fire prevention, it has high requirements on equipment materials and high costs. The metal particles after filtration are also inconvenient to recycle. Utility Model Content

[0004] In order to overcome the above-mentioned defects, the purpose of the utility model is to provide a precious metal welding smoke recovery device, which, through the improvement of the smoke recovery equipment, is more suitable for the workbench, and while meeting the suction requirements, prevents the loss of precious metals such as gold powder, thereby improving the utilization value of waste.

[0005] In order to achieve the above-mentioned purpose, the utility model provides a precious metal welding smoke recovery device, comprising a base and a smoke suction device; a workbench is provided on the top of the base, and the workbench is provided with a metal processing cavity; the smoke suction device comprises an exhaust pump and an air intake pipe; a smoke filtering device is also provided between the exhaust pump and the air intake pipe; the air intake pipe comprises a main air intake pipe, a branch air intake pipe and an intake pipe, one end of the intake pipe is connected to the branch air intake pipe, and the air inlet at the other end is located in the metal processing cavity; the intake pipe is connected to the workbench through an adjustment seat.

[0006] Preferably, the workbench is formed by enclosing three sides, and the height of the table surface close to the outer side of the workbench is lower than that of the other three sides.

[0007] Preferably, the adjustment seat includes a fixed seat, a transverse adjustment seat and a longitudinal adjustment seat, the fixed seat is fixedly connected to the workbench, an adjustment rod is provided on the transverse adjustment seat, the other end of the adjustment rod is provided with a longitudinal adjustment seat, and the longitudinal adjustment seat clamps and fixes the intake pipe.

[0008] Preferably, the lower portion of the air intake pipe is bent toward the metal processing chamber, and the air inlet of the air intake pipe is trumpet-shaped.

[0009] Preferably, each of the branch air intake pipes is provided with a regulating valve, and the regulating valve is used to control the air intake volume of the branch air intake pipe.

[0010] Preferably, the smoke filtering device comprises a shell and an air filter cartridge located in the shell, the middle portion of the air filter cartridge is connected to the air inlet end of the branch air inlet pipe, and the side of the air filter cartridge is the air outlet end.

[0011] After adopting the above technical solution, the beneficial technical effects achieved by the utility model are:

[0012] 1. Since a metal processing cavity is provided on the workbench, the air flow is reduced. When processing precious metals such as gold in the metal processing cavity of the workbench, the smoke generated almost all enters the main air intake pipe from the air intake pipe and the branch air intake pipe, which will not cause gas overflow, thus avoiding the loss of precious metals to the greatest extent. The smoke suction device includes a vacuum pump and an air intake pipe; a smoke filter device is also provided between the vacuum pump and the air intake pipe; the air intake pipe includes a main air intake pipe, a branch air intake pipe and a suction pipe, one end of the suction pipe is connected to the branch air intake pipe, and the air inlet at the other end is located in the metal processing cavity; the suction pipe is connected to the workbench through an adjustment seat. The suction pipe is connected through an adjustment seat, which is used to adjust the position of the suction pipe. On the basis of not interfering with normal jewelry processing, the smoke can be extracted faster, so that the operator can see the processing situation more intuitively.

[0013] 2. Since the smoke filtering device includes a shell and an air filter cartridge located in the shell, the air filter barrel is an existing technology. According to the actual use, a filter barrel with a suitable mesh size is selected, and the cost is extremely low. When recycling, the precious metals are quickly collected directly by burning, and then they can be quickly recovered after cleaning and replacement with chemical reagents. The operation is simple and maintenance is convenient. BRIEF DESCRIPTION OF THE DRAWINGS
