Description

Technical Field

[0001] The present invention relates to a recycled galvanized steel and a processing method thereof, in particular to a low-carbon recycled galvanized steel shell mobile power supply device and a processing method thereof, belonging to the technical field of mobile power supplies. Background Art

[0002] A mobile power bank is a portable battery charging device, usually composed of a lithium-ion battery. It can provide power to various mobile devices such as smartphones, tablets, digital cameras, etc. through a USB interface or other charging ports. Mobile power banks of different capacities can charge different devices multiple times. The advantage of mobile power banks is that they are portable and easy to carry. They can provide users with power supply anytime and anywhere, solving the problem of short battery life of mobile devices.

[0003] Nowadays, with the popularity of shared power banks and personal mobile power banks, mobile power banks are widely used. However, as the number of times the mobile power banks are used increases, their service life will be greatly reduced until they are discarded. After being discarded, the traditional method is to use high temperature to melt the mobile power bank shell, and then recycle the aluminum-zinc-plated steel inside the shell. Therefore, the aluminum-zinc-plated steel shell needs to be heated and melted. On the one hand, it will consume a certain amount of electricity or coal resources, which is not conducive to low-carbon environmental protection. On the other hand, it will produce toxic gases, threatening the life and health of the staff.

[0004] Therefore, there is an urgent need to improve the recycling of galvanized steel to solve the above-mentioned problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a low-carbon recycling galvanized steel shell mobile power supply device and a processing method thereof, wherein the galvanized steel shell of the mobile power supply is directly placed inside a crushing barrel, the galvanized steel shell is crushed by a crushing mechanism, and plastic products and metal products are separated by buoyancy. There is no need to melt the galvanized steel shell, thereby reducing the consumption of electricity resources or coal resources, and at the same time, the toxic gases generated by heating and melting will not threaten the life and health of the workers.

DETAILED DESCRIPTION

[0036] The following will describe the implementation methods of the present application in detail with reference to the accompanying drawings and examples, so that the implementation process of how the present application applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0037] like Figure 1-Figure 7As shown, the low-carbon recycling aluminum-zinc-plated steel shell mobile power supply device provided in this embodiment includes a water storage tank 1 and a recycling box 2 connected by several pumping systems 3. A crushing mechanism 5 is fixedly arranged inside the recycling box 2. The crushing mechanism 5 includes a symmetrically distributed upper hydraulic pump 501 and a lower hydraulic pump 502.

The pressing plate 504 and the lower extrusion plate 503 are both arranged inside the crushing barrel 6. The outer side of the crushing barrel 6 is provided with a number of evenly distributed crushing barrel filter holes 601. As the number of times the mobile power supply is used increases, its service life will be greatly reduced until it is discarded. After being discarded, the traditional method is to use high temperature to melt the mobile power supply shell and then recycle the aluminum-zinc steel shell inside the shell. Therefore, the aluminum-zinc steel shell needs to be heated and melted. On the one hand, it will consume a certain amount of electricity resources or coal resources, which is not conducive to low-carbon environmental protection. On the other hand, it will produce toxic gases, threatening the life and health of the staff.

When the liquid in the recovery tank 2 is pumped out, the plastic products are blocked on the first filter 4, and the metal products slide onto the second filter 7. Therefore, the plastic and metal in the galvanized steel shell can be separated. The entire process does not require the galvanized steel to be melted and incinerated, saving resources and reducing the emission of toxic gases.
