This invention belongs to the field of tower foot welding technology, specifically referring to a welding device for the feet of power angle steel towers. It includes a support frame, a transverse slide, a positioning platform, a measuring drive mechanism, a dust-collecting welding mechanism, a compressed air anti-scattering mechanism, and a controller. The transverse slide is mounted on the upper wall of the support frame, and the positioning platform is symmetrically positioned on the upper walls at both ends of the support frame. The measuring drive mechanism is mounted on the transverse slide and includes a drive component, a sliding component, and a measuring component. The drive component is located on the upper walls at both ends of the transverse slide, the sliding component is located on the upper wall of the transverse slide, and the measuring component is located on the side wall of the drive component. This invention provides a welding device for the feet of power angle steel towers capable of collecting welding fumes generated during the welding process and compressing the dust particles in the welding fumes into a cake to prevent secondary diffusion of the fumes.

The utility model provides a kind of acid precipitation reaction device for salicylic acid production, it is related to chemical production equipment technical field, including reaction tank, the top of the reaction tank is fixedly connected with top cover, the top right side of the top cover is equipped with the feed inlet that passes up and down, the bottom right side of the reaction tank is fixedly connected with collecting tube.The utility model after acid precipitation reaction is completed, precipitate falls into the storage tank in left side, first motor is started at this time, its drive rotating disc rotates, drives the storage tank position of left and right sides to be transposed, the storage tank with precipitate is rotated to right side and is aligned with collecting tube, precipitate falls into collecting box by gravity, simultaneously, empty storage tank is rotated to left side and is aligned with the bottom of conical precipitation area, and new precipitate is received, so circulation realizes the sustained automatic separation of precipitate and supernatant, greatly reduces labor intensity, shortens production cycle, and avoids impurity introduction, significantly improves separation efficiency and product quality.

The application relates to the technical field of water pollution treatment, in particular to a zinc-containing wastewater treatment and recycling device for electroplating production lines. The device comprises a shell, a water inlet part and a first water outlet part are arranged on the shell, a sedimentation shell and a filter are arranged in the shell, interval distributed sedimentation chambers are arranged in the sedimentation shell, adjacent sedimentation chambers are communicated through connecting channels, the sedimentation shell divides the internal space of the shell into two parts of a first chamber and a second chamber, the filter is arranged in the second chamber, and the first chamber and the second chamber are communicated with adjacent sedimentation chambers through the connecting channels. The zinc-containing wastewater is provided with a chemical precipitation space through the sedimentation chambers, so that the zinc content and the sediment content in the wastewater are reduced, the filter is combined to carry out membrane separation treatment on the wastewater, the impurities in the wastewater are deeply purified, the wastewater reaches the recycling standard, the probability that the sediment blocks the filter is reduced, and the wastewater treatment effect is improved.
