Description

电镀用气浮槽 Electroplating flotation tank

技术领域 FIELD

[0001] 本发明涉及一种电镀设备,具体地说是电镀过程中用来对电镀废液进行净化处理的气浮槽。 [0001] The present invention relates to an electroplating device, the electroplating process is used in particular for electroplating waste purification treatment flotation tank.

背景技术 Background technique

[0002]目前,在电镀生产线上,用来对电镀废液进行净化处理大多使用气浮槽,气浮槽的工作原理是先将电镀废液引入气浮槽内的反应区,再利用溶气罐将水、压缩气溶合成水溶气,然后将水溶气通过释放头释放到反应区内与电镀废液反应,使电镀废液中的淤泥与水分离并在电镀槽内的沉淀区进行沉淀,沉淀区内的水再通过溢流管道进入清水区,清水区内的清水可供后续工序使用。 [0002] Currently, in a plating line for plating waste liquid purification flotation tank is often used, the principle of the flotation tank is introduced into the first reaction zone, electroplating waste flotation tank, dissolved air recycling the water tank, the compressed gas dissolved water soluble synthesis gas, then the gas is released into the aqueous reaction zone effluent discharge head through the plating reaction, the plating waste liquid separated from the water and sludge precipitated in the precipitation zone of the plating bath, water re-entry zone precipitation zone through the overflow water pipe, water water zone used for the subsequent step. 传统的气浮槽其溶气罐通过管道与槽体内的沉淀区相连通,从而可从沉淀区内取水并与压缩气溶合,为槽体内的反应区提供水溶气。 Conventional flotation tank through a conduit groove which was dissolved groove communicating vivo precipitation zone, thereby fusion with the water and compressed gas from the precipitation zone, to provide an aqueous gas reaction zone as a groove in the body. 这种气浮槽的缺点在于沉淀区内的淤泥沉淀需要经过一定的时间,而溶气罐在沉淀区取水是连续作业,因此在取水过程中很容易将还未沉淀至沉淀区底部的淤泥带入溶气罐,而经由溶气罐混合而成的水溶气也会带有少量淤泥,长期使用后会导致溶气罐内的管道和水溶气的释放头被淤泥堵塞,需要经常清理,从而增加了气浮槽的维修和保养成本。 A disadvantage of this is that the flotation tank sludge precipitation zone precipitation takes some time, the water tank is continuously dissolved during the precipitation operation area, it is easy in the process water has not settle to the bottom of the sludge with precipitation zone into the solution tank, and the mixed gas through the aqueous solution tank with a small amount of sludge will after long-term use can lead to release the head pipe and the gas in the aqueous solution tank is silted, require frequent cleaning, thereby increasing repair and maintenance costs of the flotation tank.

发明内容 SUMMARY

[0003] 本发明要解决的问题是提供一种电镀用气浮槽,采用该气浮槽,可降低维修和保养成本。 [0003] The problem to be solved according to the present invention is to provide a flotation tank plating, using the flotation tank, repair and maintenance costs can be reduced.

[0004] 为解决上述问题,采取以下方案: [0004] To solve the problem, take the following program:

本发明的电镀用气浮槽包括槽体,槽体内有第一隔板和第二隔板,槽体内腔有反应区、沉淀区和清水区,第一隔板位于反应区和沉淀区之间,第二隔板位于沉淀区和清水区之间。 Electroplating flotation tank according to the present invention comprises a tank body, the body has a first groove and a second separator separator tank body cavity having a reaction zone, a settling zone and water zone, a first reaction zone and a separator positioned between the settling zone a second separator positioned between the precipitation zone and the water zone. 反应区的底部有废水进口,废水进口的上方有释放头,反应区对应的槽体外壁上有溶气罐,溶气罐通过管道与释放头相连接。 Bottom of the reaction zone of the inlet waste water, waste water inlet above the head with a release in vitro walls have grooves corresponding to the reaction zone melting tank, dissolved gas cylinders connected by a conduit to the discharge head. 沉淀区内有横向的水管,水管上有若干水孔,所述水管从第二隔板穿过并伸入清水区,水管与第二隔板间呈密封固定。 The precipitate lateral pipes area, there are several holes on the water pipe, and into the water passing through the water separator from the second region, between the pipe and a second seal separator was fixed. 清水区内在水管上方有竖向的溢流管,溢流管通过弯管与水管相连接。 Water area above the vertical pipe there is an overflow pipe through the overflow pipe elbow is connected to the water pipe. 其特点是所述清水区对应的槽体侧壁上有开孔,溶气罐通过取水管道从槽体外侧与该开孔相连通。 Characterized in that said water region corresponding to the groove side wall with an opening, the opening dissolved gas cylinders connected by a water pipe from the outside through the tank.

[0005] 采取上述方案,具有以下优点: [0005] taking the above embodiment has the following advantages:

由上述方案可知,由于本发明的电镀用气浮槽的清水区对应的槽体侧壁上有开孔,溶气罐通过取水管道与该开孔相连通,从而将溶气罐的取水点由沉淀区变更为清水区,清水区内的水经过沉淀和溢流后不再有淤泥混杂,即使长期使用,也不会导致溶气罐内的管道和水溶气的释放头堵塞,使得气浮槽的维修和保养成本大大降低。 Seen from the above embodiment, since the water flotation tank plating regions of the present invention corresponds to the groove side wall with an opening, dissolved gas cylinders through intake conduit communicating with the opening, so that the melting point of water by the tank precipitation zone area was changed to water, water, water and precipitation zone after the overflow is no longer mixed sludge, long-term use, and will not result in the release of the head pipe and a soluble gas dissolved in the tank clogging, such flotation tank repair and maintenance costs are significantly reduced.
