A hot-dip galvanized washing pool with automatic circulation function

Abstract

The invention discloses a hot-galvanized water washing pool with an automatic circulating function. The pool comprises a control device, a water washing pool body, a drainage device and a water feeding device; the water washing pool body comprises a pool wall and a pool bottom; a water quality monitoring device is arranged above the pool wall; the drainage device comprises a water outlet pipe and a water outlet pump; the water outlet pipe is arranged above the pool wall, and is bonded near the pool bottom; the water feeding device comprises a water inlet pipe and a water injecting and extracting pump; the water inlet pipe is arranged in the connected place of the pool wall with the pool bottom; a pipe port of the water inlet pipe is formed in the inclined upper side; the water outlet pipe and the water inlet pipe are oppositely arranged; the pumping speed of the water outlet pump is higher than the water injecting speed of the water injecting and extracting pump; and the water quality monitoring device, the water outlet pump and the water injecting and extracting pump are respectively connected with the control device. The water washing pool can perform quick water circulation, can fully discharge such precipitations as impurities and acid liquid outside to save the water change time, and can guarantee the water quality after water change.

Description

technical field [0001] The invention relates to a hot-dip galvanizing washing pool with automatic circulation function, which is especially suitable for washing treatment in hot-dip galvanizing treatment. Background technique [0002] The general hot-dip galvanizing process includes material preparation, pickling, water washing, fluxing, galvanizing, cooling, passivation and grinding. Among them, acid will remain on the pickled steel, and the acid will affect the steel. The effect of galvanizing treatment, so the pickled steel must be washed to remove excess acid. When the clean water in the washing pool is used for a long time, there will be sediments such as impurities in it, which will make the water in the washing pool turbid, and it also contains a certain concentration of acid, so such a washing pool cannot Therefore, it is necessary to change the water in the washing tank, and the general operation method for changing the water in the washing tank is to change the wa...

Problems solved by technology

When the clean water in the washing pool is used for a long time, there will be sediments such as impurities in it, which will make the water in the washing pool turbid, and it also contains a certain concentration of acid, so such a washing pool cannot Therefore, it is necessary to change the water in the washing tank, and the general operation method for changing the water in the washing tank is to change the water manually, but because the volume of the washing tank is generally relatively small Large, so workers need to spend a lot of time to change the water, and manual water change can not clean the water containing impurities and acid, and the impurities deposited at the bottom of the pool will still remain in the bottom of the pool, so it will still affect the process. Water quality after water change
