Abstract

The invention provides an acid mist absorbing device for steel pipe pretreatment. The acid mist absorbing device comprises fixed mist absorbing hoods and lifting mist absorbing hoods, wherein a fixedair suction pipe is connected with the top of each fixed mist absorbing hood; the lifting mist absorbing hoods are arranged on the front sides of the fixed mist absorbing hoods, and a telescopic softair pipe is connected between the top of each lifting mist absorbing hood and the corresponding fixed air suction pipe; and the left side or the right side of each lifting mist absorbing hood is hinged to a supporting upright column, a winch is further arranged at the top end of each supporting upright column, and a rope of each winch passes over the top of the corresponding lifting mist absorbinghood to be fixedly connected with the upper part of the right side of the corresponding lifting mist absorbing hood. According to the acid mist absorbing device for the steel pipe pretreatment, the ropes are driven by the winches to control the lifting mist absorbing hoods to rotate up and down, the horizontal moving space is provided for hoisting a steel pipe bundle, and the situation of mutualinterference between the mist absorbing hoods and a crown block is effectively avoided; and meanwhile, gaps between the lifting mist absorbing hoods and an acid tank can be further reduced, the overflow of acid steam is effectively avoided, the pollution is reduced to the maximum degree, and the health of an operator and the cleanness of the environment are ensured.

Description

technical field [0001] The invention belongs to the field of galvanizing processing of steel pipes, and in particular relates to an auxiliary device for pretreatment of steel pipes. Background technique [0002] In the prior art, before the steel pipes are hot-dip galvanized, it is necessary to put the bundled steel pipe bundles into the acid pool for degreasing and derusting. The transportation of steel pipe bundles is generally carried out by hoisting, but the hoisting cranes are generally installed on the top of the factory building or at a relatively high position. It will interfere with the hoisting rope of the hoisting crane and cannot work normally. However, the operating cost of other mist absorbing devices is relatively high, and the mist absorption effect is not satisfactory. Contents of the invention [0003] In view of this, the present invention aims to propose an acid mist absorption device for steel pipe pretreatment to solve the problem in the prior art t...
