Description
Technical Field
The utility model belongs to the technical field of the processing of the smoke and dust pollution of brazing of metallized film such as direct current support capacitor, locomotive electric capacity and specifically relates to a portable local exhaust device of metallized film capacitor brazing.
Background
The connection between elements of metallized films such as direct current support capacitors, locomotive capacitors and the like is connected with a zinc-sprayed layer on the end surface of the elements by brazing through copper stranded wires, a large amount of brazing smoke is generated by brazing, hundreds of welding points are arranged on each capacitor, some brazing smoke contain lead, and the brazing smoke is inhaled to be harmful to human bodies. The brazing smoke dust generated in the production process is quickly sucked away, so that operators do not suck the smoke dust, and the maintenance of a clean and qualified working environment is the basic requirement of occupational health. However, the smoke dust is rapidly sucked away in the brazing process, the smoke dust is not easy to realize in the brazing of the metallized film capacitor element, the air draft effect is considered, and the convenience of operation is also considered. There are mainly the following reasons:
① the smoke generated in the production process is exhausted quickly and not in contact with human body according to the ventilation principle, the traditional method has two air exhaust modes, the first mode is to put the workpiece in the closed space to keep the negative pressure of the closed space and the human body operates outside the closed space, the second mode is to adopt the air speed of the air exhaust to control the smoke and dust, so that the smoke and dust is sucked away quickly and not sucked by the operator.
② the first venting mode is certainly not feasible because soldering of the operating capacitor requires the upper half of the operator to be above the workpiece.
③ the air-discharging modes of smoke dust controlled by the wind speed of discharged air include side air outlet air-discharging mode and top air outlet air-discharging mode.Because the soldering periphery of the capacitor is an operation surface, only a top air port air exhaust mode can be adopted, according to the size of the capacitor (100 plus 1000) mm × (300 plus 1000) mm, the minimum size of the reasonably designed exhaust hood is 1000mm × 1200mm, the exhaust hood is 1000mm away from the upper surface of the product, the smoke dust is well controlled, the air exhaust speed of the dust generating point is effective when reaching more than 0.3m/s, and according to the calculation, the air volume of each exhaust hood is 6000m3H, the total of two exhaust hoods in each room is 12000m3H is used as the reference value. The soldering of the gold film capacitor is carried out in a constant temperature and humidity room, and 12000m is supplemented to each room3The treated fresh air is very expensive and almost impossible to realize. Meanwhile, when the wind is sucked upwards, the smoke dust passes through the head of a person in the flowing process, and even if the smoke dust in a room is sucked cleanly, an operator can suck the smoke dust.
In summary, the conventional ventilation and dust removal device cannot solve the problem that the smoke dust of the capacitor brazing is sucked by an operator, so the invention provides a mobile ventilation device which adopts a local air draft method to solve the problem.

3. Can not be inhaled by human body: the smoke dust is in a fully sealed or negative pressure state in the flowing process, and the smoke dust is in the soft air pipe when passing through the head of an operator and cannot be inhaled by people.
4. The operation is convenient: the axial flow fan can move back and forth and left and right through the four tracks, and on the welding surface of 700 x 1000, the air suction opening of the soft air pipe can be at any position of the welding surface only by slightly pulling.
