Air extracting device for electroplating equipment

Abstract

The invention discloses an air extracting device for electroplating equipment. The air extracting device is assembled on an electroplating bath of the electroplating equipment and comprises an air extracting cap, a fan and a main air extracting branch pipe connected between the air extracting cap and the fan, wherein the main air extracting branch pipe is connected with the fan in a slope form; the air extracting cap comprises an air extracting pipe; auxiliary current limiting plates extend from the air outlet end of the air extracting pipe towards both sides; a flow guide plate is arranged inside the air outlet end of the air extracting pipe; the side wall of the air extracting pipe is provided with a plurality of elliptical air extracting bar apertures; and the total sectional area of the air extracting bar apertures is equal to the sectional area of the air extracting pipe. The main air extracting branch pipe of the air extracting device for the electroplating equipment is connected with the air extracting cap in the slope form, so that the influence of the accumulation of cooling water in the main air extracting branch pipe on the air extracting effect is eliminated; and the air outlet of the air extracting pipe is provided with the auxiliary current limiting plates, so that the dissipation of waste gas in the electroplating bath can be prevented effectively and the waste gas can be extracted rapidly. The air extracting device has a simple structure, is easy to implement, has good air extracting effect and saves cost.

Description

technical field [0001] The invention relates to an auxiliary production equipment for electroplating lines, in particular to a high-efficiency air extraction device for electroplating equipment. Background technique [0002] As we all know, harmful gases will be generated in electroplating production, and the harmful gases must be exhausted and purified before they can be discharged to meet the requirements of clean production. In the form of exhaust air, the exhaust air volume of the plating tank is considered from a single point of view. If the exhaust effect is to be improved, it is necessary to consider the exhaust air volume too much. Generally, an excessively large fan is used for exhaust air, which not only consumes a lot of power resources, but also increases the The cost of electroplating, and the connection between the exhaust hood and the exhaust main branch pipe is mostly a downslope connection, so the cooling water in the exhaust main branch pipe is easy to accu...

Problems solved by technology

[0002] As we all know, harmful gases will be generated in electroplating production, and the harmful gases must be exhausted and purified before being discharged to meet the requirements of clean production. For ventilation and other forms, consider the ventilation volume of the plating tank only. If you want to improve the ventilation effect, you need to consider the ventilation volume too much, and generally use a large fan for ventilation, which not only consumes a lot of power resources, but also increases. The cost of electroplating, and the connection between the exhaust hood and the exhaust main branch pipe is mostly downhill, so the cooling water in the exhaust main branch pipe is easy to accumulate at the bottom, affecting the ventilation effect
