Description

Technical Field

[0001] The utility model relates to hot-dip galvanizing slag recovery equipment. Background Art

[0002] During the hot-dip galvanizing process, metal articles are typically dipped into molten zinc to form a protective zinc coating.

[0003] In the hot-dip galvanizing process, metal products are immersed in molten zinc to form a zinc coating. During this process, the zinc liquid may contain some metal impurities, such as iron, aluminum, etc. When the metal products are leached out of the zinc liquid, these metal impurities may condense into solid particles to form metal slag.

[0004] Oxides: During the hot-dip galvanizing process, the surface of the metal product may react with oxygen in the air to form oxides. These oxides may exist in the zinc liquid in the form of solid particles and become slag.

[0005] Residues: Metal products may need to go through some pre-treatment steps before hot-dip galvanizing, such as pickling, degreasing, etc. The chemicals used in these pre-treatment processes or residual grease may be converted into solid residues during the hot-dip galvanizing process and become part of the slag. These slags need to be effectively collected and treated to avoid environmental pollution and waste of resources.

[0006] At present, some hot-dip galvanizing slag recovery equipment uses a collecting tank to collect the slag and quickly cools and solidifies it through cooling water.

[0007] There are some challenges in the existing technology in the hot-dip galvanizing slag recovery process, mainly in the effective separation of metal filter residue, oxides and floating objects. The existing method can only simply separate the metal slag and floating objects, the separation efficiency is low, and a manual cleaning device is also required, and the use effect is not ideal. Therefore, a hot-dip galvanizing slag recovery device is proposed. Utility Model Content

[0012] Preferably, the guide plate is arranged obliquely, and the end of the guide plate is connected to the polymer assembly through a partition, and a plurality of through holes for guiding out powder particles are opened on the surface of the guide plate.

[0013] Preferably, the polymerization assembly comprises a polymerization basket, one side of the polymerization basket is provided with a connecting shaft cylinder, and the inner wall of the connecting shaft cylinder is provided with a lead screw.

[0022] The utility model can effectively separate metal filter residues, powder precipitates and floating objects through the arranged guide plates, polymerization components and adsorption components, thereby improving the separation efficiency.

[0023] Through the inclined design of the magnetic sheet and the guide plate in the adsorption component, the metal particles mixed with a small amount of zinc material or pure iron can be adsorbed and collected by the magnetic sheet when they slide on the surface of the guide plate. At the same time, since the zinc material is not magnetic, it cannot be adsorbed by the magnetic sheet and will not stay on the surface of the guide plate. This can improve the classification efficiency between iron materials and zinc materials and improve the recycling effect.

The technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] See also Figure 1-5 The utility model provides a hot dip galvanizing slag recovery device, comprising a collection tank 100 for hot dip galvanizing slag recovery, wherein a guide plate 200 for slag sliding is arranged inside the collection tank 100, and a polymerizing component 300 for collecting solid particles is arranged at the tail end of the guide plate 200.

[0037] The adsorption assembly 400 includes a magnetic sheet 401 embedded in the lower part of the guide plate 200. The magnetic sheets 401 are staggered and one end of the magnetic sheet 401 is set at an acute angle so that subsequent slag can slide down along the inclined surface of the metal particles adsorbed on the surface of the guide plate 200.

[0038] The guide plate 200 is disposed obliquely, and the end of the guide plate 200 is connected to the polymer assembly 300 through a partition 500. A plurality of through holes 201 for guiding powder particles are provided on the surface of the guide plate 200.

[0039] The polymerization assembly 300 includes a polymerization basket 301, a connecting shaft cylinder 302 is provided on one side of the polymerization basket 301, a lead screw 303 is provided on the inner wall of the connecting shaft cylinder 302, a transmission gear 304 is provided at the bottom end of the lead screw 303, a driving gear 305 is meshed and connected to one side of the transmission gear 304, and the input end of the driving gear 305 is connected to the output end of the transmission motor 306 located at the lower part of the collection tank 100. A clamping plate 301a is provided on one side of the polymerization basket 301, and a connecting groove 302a is provided on the side of the connecting shaft cylinder 302 closer to the polymerization basket 301, and the polymerization basket 301 is connected to the connecting groove 302a of the connecting shaft cylinder 302 through the clamping plate 301a.
