Description

Acid gas fog collecting cover Technical Field The utility model relates to the technical field of acid aerosol collection, in particular to an acid aerosol collection cover. Background Electrolytic copper foil is an important material for manufacturing Copper Clad Laminate (CCL), printed Circuit Board (PCB) and lithium ion battery. In the current high-speed development of the electronic information industry, the electrolytic copper foil is called a 'neural network' for transmitting and communicating signals and power of electronic products. The electrolytic copper foil is formed by depositing copper ions in electrolyte on a smooth rotary titanium plate circular cathode roller, and because copper sulfate solution is used as the electrolyte in the production process of the copper foil, a large amount of sulfuric acid mist acid waste gas is generated in the production process of the electrolytic copper foil without treatment, the quality of the copper foil is affected, the defects of acid mist points and the like are generated, the environment is polluted, the human health is endangered, and the copper foil is subjected to treatment and standard discharge according to environmental protection regulations, so that an acid mist treatment link is added in the foil production process. The acid mist is collected on the premise of acid mist treatment, when the current copper foil is produced, the acid mist is generally dissipated from gaps near the opening of the anode tank, and the acid mist in the production process is pumped out by arranging an exhaust pipe around the gaps, so that the acid mist collection mode cannot have a sealing effect, only part of the acid mist can be pumped out, if the sealing effect is poor, the dissipation of the acid mist cannot be prevented, mist gas still escapes from gaps at the edge of the anode tank and is dispersed into the air, and negative effects are caused on production and environment. Disclosure of utility model Aiming at the defects of the prior art, the utility model aims to provide an acid gas mist collecting cover, which aims to solve the problem that the escape of sulfuric acid mist in the production process of electrolytic copper foil in the prior art has negative influence on production and environment. In order to achieve the above purpose, the embodiment of the utility model is achieved through the following technical scheme that a first plate body, a second plate body and a baffle are arranged along the outer periphery of the first plate body, the baffle is perpendicular to the first plate body, one end of the baffle, which faces away from the first plate body, is connected with the second plate body, a cavity is formed by encircling the first plate body, the second plate body and the baffle, an opening communicated with the cavity is formed in the baffle, the opening is matched with a gap at one end of an opening of an anode groove so that escaping acid mist enters the cavity, an exhaust port matched with an exhaust pipe is formed in the second plate body, the exhaust port is communicated with the cavity, the exhaust port is used for being connected with an exhaust fan, one surface of the first plate body, which faces away from the first plate body, is fixedly connected with the second plate body, one end of the first plate body, which faces away from the first plate body, is provided with the first plate body, the first plate body is arranged on the first connecting plate body, the second plate body is arranged on the first connecting plate body, the first connecting plate is arranged on the first connecting plate body, the second connecting plate is arranged on the first connecting plate is close to the first connecting plate, the first connecting plate is arranged on the first connecting plate, and the second connecting plate is arranged on the first connecting plate. Compared with the prior art, the utility model has the beneficial effects that the first plate body, the second plate body and the baffle are mutually connected and enclosed to form the cavity, the opening is butted with the gap at one end of the opening of the anode groove, a closed environment is formed at the gap at one end of the opening of the anode groove, acid mist generated in the production process of the electrolytic copper foil is dissipated to the cavity and is pumped away by the exhaust fan, and compared with the conventional mode of cleaning the acid mist, the negative influence of the acid mist dissipation on the production environment and the health of workers can be effectively reduced, meanwhile, the collecting cover can play a role of shielding protection on the positions of the anode groove and the cathode roller, and the reinforcing plate is arranged in the cavity, so that the integral strength of the collecting cover is further improved, the collecting cover is firm and durable, and the collecting cover is fixed by using bolts, thereby preventing the shaking displacement phen
