Description

Technical Field

[0001] The utility model relates to the technical field of zinc smelting and purification, and more specifically to an environmentally friendly device for adding alloy zinc powder. Background Art

[0002] When smelting zinc, because zinc contains other impurities, it is necessary to remove the impurities from the zinc solution by adding other chemical substances to react with the impurities and precipitate the reactants. The existing zinc smelting purification tank is composed of a tank body, a zinc powder feed pipe, an air pump and other components. When zinc powder is added directly from the feed pipe, it is easy to cause dust overflow, causing the air pump to inhale more zinc powder under negative pressure, resulting in a waste of zinc powder. At the same time, after the zinc powder is directly added, it floats on the surface of the liquid and contacts the inner wall of the purification tank, which is easy to cause scaling of the tank wall. Therefore, in order to reduce the waste of zinc powder and scaling of the purification tank tank wall, the staff installed a zinc powder slurrying device at the feed pipe.

[0003] The existing zinc powder slurrying device generally adopts a slurrying tank, which is used to pump the slurry liquid (a post-liquid in the zinc smelting purification process) into the slurrying tank, and then add it to the purification tank after it is fully blended with the zinc powder through an electric stirrer. However, the scaling of the zinc powder slurrying causes the zinc powder to react with the slurry liquid during the mixing and stirring process, resulting in a decrease in the activity of the zinc powder when it is added to the purification tank, and the purification efficiency is greatly reduced. Utility Model Content

[0004] The purpose of the utility model is to solve the above technical problems and provide an environmentally friendly device for adding zinc alloy powder, which can reduce zinc powder emission, reduce flying loss, and alleviate equipment scaling, while also ensuring the effective utilization rate of zinc powder and reducing production costs.

[0005] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical scheme: an environmentally friendly device for adding alloy zinc powder, comprising a purification tank, an air extraction cylinder is installed on the upper end surface of the purification tank, a slurrying tank is arranged above the purification tank, the slurrying tank is inclined downward at one end close to the purification tank, a cover body is arranged on the top of the slurrying tank, the upper end surface of the cover body is connected with a feed pipe and a plurality of lower liquid pipes, and a discharge pipe is connected between the lower end surface of the slurrying tank and the air extraction cylinder.

[0006] In order to facilitate the rapid flushing of the alloy zinc powder into the purification tank, as a preferred device for adding environmentally friendly alloy zinc powder of the utility model, the liquid outlet ends of the plurality of lower liquid pipes are all higher than the material outlet end of the material outlet pipe.

[0007] In order to facilitate the entry of the primary liquid into the lower liquid pipe during the zinc smelting purification process, as a preferred device for adding environmentally friendly alloy zinc powder in the utility model, the liquid inlet ends of several of the lower liquid pipes are detachably connected to the purified liquid pipeline through a sealing flange.

[0008] In order to stabilize and fix the position of the slurrying tank, as a preferred device for adding environmentally friendly alloy zinc powder of the utility model, a bracket is installed between the slurrying tank and the purification tank.

[0009] In order to facilitate the installation of the bracket, as a preferred device for adding environmentally friendly alloy zinc powder in the utility model, the upper end of the bracket is fixedly connected to the slurry tank, and the lower end of the bracket is detachably connected with a fixing hoop, and the fixing hoop is fixedly connected to the outer side of the purification tank.

[0010] The beneficial effects of the utility model are as follows:

[0011] The alloy zinc powder enters the slurry tank through the feed pipe. At this time, the slurry liquid enters the slurry tank through the lower liquid pipe and flushes the alloy zinc powder, and then the alloy zinc powder and the slurry liquid are quickly mixed and flushed into the purification tank through the discharge pipe. The device adopts a flushing feeding mode to avoid the reaction between the zinc powder and the slurry liquid due to too long mixing and stirring time, resulting in reduced activity of the zinc powder. At the same time, it effectively reduces the zinc powder flying loss and equipment scaling caused by the feeder directly adding zinc powder to the reaction tank. BRIEF DESCRIPTION OF THE DRAWINGS
