De-painting kiln for pop can

Abstract

The invention discloses a de-painting kiln for a pop can. The de-painting kiln comprises a combustion chamber, a feeding device, a de-painting roller and a tail discharging device, wherein the inside cavity of the combustion chamber comprises an upper cavity and a lower cavity; the lower cavity is a combustion area and is provided with a burner and a discharging tube; the burner is used for directly combusting fuels so as to supply heat energy; the upper cavity is a heat supply cavity which is directly communicated with the de-painting roller; the tail discharging device is arranged on the tail of the de-painting roller and is a one-way blanking sealing device; a smoke outlet is arranged on the wall of the de-painting roller above the outlet of the de-painting roller; the feeding device comprises a hopper type container and a feeding pipe; the bottom of the container is connected to the feeding pipe; the one-way blanking sealing device is arranged at the joint of the container and the feeding pipe; a discharge hole on the bottom of the feeding pipe is extended into the de-painting roller; and a spiral rotating plate is arranged on the inner wall of the middle section of the de-painting roller. The de-painting process is realized by utilizing heat energy, and the de-painting kiln for the pop can has the characteristics of multifunction, high de-painting efficiency, high speed, energy conservation and environmental friendliness. The structure is simple and the cost is low. The de-painting kiln can be used for removing the paintings and attachments on the surface of the pop can.

Description

technical field [0001] The invention relates to a device for removing paint and attachments on the surface of waste aluminum cans. Background technique [0002] With the development of my country's economy and society and the improvement of people's living standards, the consumption of aluminum cans in my country has increased year by year, and has increased exponentially. The aluminum can body of the can is 3004 grade aluminum alloy, and the can lid is 5182 grade aluminum alloy. These high-quality aluminum alloys are all made of high-quality primary aluminum. At present, the recycled cans in our country are all downgraded and used, and made into low-grade aluminum alloy ingots such as sub-brand 102, ADC-12, non-standard aluminum ingots, etc., so that their real value has not been utilized, causing great economic losses. Big waste. The recovered waste aluminum cans are made into 3004 aluminum alloys that meet national standards through the preparation technology of grade-r...

Problems solved by technology

This is also a widely used method at present, but the paint removal rate is significantly affected by the concentration of the organic solution, and it cannot guarantee 100% paint removal of aluminum, and it is difficult to connect with the upper and lower processes in the entire recycling process of waste aluminum cans, and it is difficult to form a certain scale.
