Description

Technical Field

[0001] The present invention relates to the technical field of aluminum alloy recycling, and specifically to a recycling and crushing device and method for waste aluminum alloy materials. Background Art

[0002] When using aluminum alloy profiles, other alloy metal components are usually used as connectors. These connectors are often made of iron. During recycling, they are usually directly melted at high temperature, which leads to an increase in the content of iron elements, reduces the mechanical properties of the aluminum alloy, and weakens its corrosion resistance, resulting in generally poor quality of recycled castings of aluminum alloy profiles. In an aluminum alloy profile waste environmental protection recycling and treatment device with the application number CN2019112199150, it includes a metal crusher and a primary conveying mechanism arranged behind the metal crusher to remove the iron materials mixed in the aluminum alloy profiles, so as to ensure the content of iron elements in the recycled aluminum alloy and avoid the problem that the content of iron elements is too high and affects the quality of the recycled and cast aluminum alloy.

[0003] Although this device has the above advantages, when in use, there are still the following defects:

[0004] When this device crushes aluminum alloy materials through an existing crusher, it is easy to cause the sizes of the crushed materials of the aluminum alloy materials to be inconsistent. On the one hand, it will affect the consistency of subsequent melting. On the other hand, during the magnetic separation process, the iron-containing crushed materials will carry away a large amount of aluminum alloy materials, resulting in a reduction in the recovery rate of the aluminum alloy materials;

[0005] During the recycling process of this device, the aluminum alloy materials are separated from plastics and dried through two heating processes, and the heating methods are relatively traditional. It is necessary to heat the air, and the heat will be dissipated after heating, resulting in an increase in recycling costs and waste of thermal energy.

[0017] The present invention also discloses a crushing method for a waste aluminum alloy material recycling and crushing device, which specifically includes the following steps:

[0018] Step 1: First, place the aluminum alloy material to be recycled on the support rollers. The support rollers rotate to convey the aluminum alloy material. During the conveying process, the output end of the telescopic rod pushes two push plates to approach each other to laterally protect the aluminum alloy material. When the aluminum alloy material moves onto the support plate, the output end of the lifting rod drives two rotating rollers to descend. One rotating roller quantitatively cuts the aluminum alloy material through a cutting ring and cutting strips. The other rotating roller applies a pressure holding force to the aluminum alloy material through the elastic force of the spring rod.

[0019] Step 2: The quantitatively cut aluminum alloy material continues to move. The magnetic separator separates the iron-containing aluminum alloy material by magnetic adsorption. Then the remaining aluminum alloy material falls into the hopper and enters the inside of the stirring kettle through the material pipe. When moving inside the material pipe, the aluminum alloy material is heated and raised in temperature through the induction heating of the spiral coil, so that the plastic on the aluminum alloy material melts.

[0020] Step 3: After the aluminum alloy material enters the interior of the stirring kettle, it falls into the liquid water. The molten plastic cools and solidifies. At the same time, through the high-speed stirring of the stirrer, the plastic and the aluminum alloy material are separated. Meanwhile, the surface of the aluminum alloy is cleaned. Then, through the action of the liquid pump and the filter plate, the liquid water circulates to filter impurities. Then, the plastic and the aluminum alloy material fall onto the eddy current separator through the separation pipe. The eddy current separator conveys the plastic and the aluminum alloy material, and performs sorting through eddy currents at the end of the conveying. Meanwhile, the fixed ring absorbs the heat of the liquid water. Then, the fan works to blow the heat through the air pipe and the air holes towards the moving plastic and aluminum alloy material for drying. Beneficial effects

[0021] The present invention provides a recycling and crushing device and a crushing method for waste aluminum alloy materials. Compared with the prior art, the following beneficial effects are achieved:

[0022] (1) By setting a cutting device, the aluminum alloy material can be abutted by the two side rollers to maintain its stability. And one side roller can uniformly cut the aluminum alloy material through the cutting ring and the cutting strip, so as to facilitate the subsequent melting consistency, and make the size of the cutting fragments uniform. On the one hand, it is convenient for subsequent heat treatment, and on the other hand, it also reduces the waste of aluminum alloy during magnetic separation, thereby improving the recovery rate of the aluminum alloy material.

[0023] (2) By setting a feeding assembly, the rotation of the supporting rollers can convey and feed the aluminum alloy material, and through the clamping of the two side push plates, it is convenient to laterally protect the aluminum alloy material, so as to improve the stability of the aluminum alloy material and facilitate maintaining the uniformity of cutting.

[0024] (3) By setting an aggregate assembly, the iron-containing fragments can be sorted by a magnetic separator, and then the remaining aluminum alloy fragments are uniformly discharged through the hopper and the material pipe. Meanwhile, during the material falling process, through the induction heating of the spiral coil, on the one hand, it is convenient for separating aluminum from plastic, and on the other hand, it can directly heat the aluminum alloy. It can not only improve the heating efficiency and effect, but also avoid the problems of heat waste caused by heating the air and increased cost.

[0025] (4) By setting a separation unit, through the cooperation of the stirrer and the liquid water, the plastic can be solidified, and through stirring, the plastic and the aluminum alloy can be separated. Meanwhile, not only can the aluminum alloy and the plastic be cleaned, but also the heat during heating can be recovered, thus avoiding heat waste.

[0026] (5) By setting a drying module, the fixed ring can replace the thermal energy of the liquid water. The fan works to carry the thermal energy through the air flow, and through the action of the air pipe and the air holes, it blows towards the conveyed plastic and aluminum alloy material for drying, so that the thermal energy can be continuously used and heat waste is avoided.

During the transportation process, the output end of the telescopic rod 46 pushes the two push plates 43 to approach each other to protect the aluminum alloy material. When the aluminum alloy material moves onto the support plate 3, the output end of the lifting rod 10 drives the two rollers 2 to descend. The roller 2 on one side quantitatively cuts the aluminum alloy material through the cutting ring 12 and the cutting strip 13, and the roller 2 on the other side maintains the pressure of the aluminum alloy material through the elastic force of the spring rod 9;

7. A crushing method for a recycling and crushing device of waste aluminum alloy materials, characterized in that: Using a waste aluminum alloy material recycling and crushing device according to claim 6, specifically including the following steps: Step 1: First, place the aluminum alloy material to be recycled on the support rollers (41). The support rollers (41) rotate to convey the aluminum alloy material. During the conveying process, the output end of the telescopic rod (46) pushes two push plates (43) to approach each other to laterally protect the aluminum alloy material. When the aluminum alloy material moves onto the support plate (3), the output end of the lifting rod (10) drives two rotating rollers (2) to descend. One side of the rotating roller (2) quantitatively cuts the aluminum alloy material through the cutting ring (12) and the cutting strip (13). The other side of the rotating roller (2) applies pressure to the aluminum alloy material through the elastic force of the spring rod (9). Step 2: The quantitatively cut aluminum alloy material continues to move. The magnetic separator (55) sorts the aluminum alloy material containing iron by magnetic adsorption. Then the remaining aluminum alloy material falls into the hopper (51) and then into the stirring kettle (531) through the material pipe (52). When moving inside the material pipe (52), the aluminum alloy material is heated by the induction heating of the spiral coil (56), causing the plastic on the aluminum alloy material to melt. Step 3: After the aluminum alloy material enters the stirring kettle (531), it falls into the liquid water. The molten plastic cools and solidifies. At the same time, through the high-speed stirring of the stirrer (532), the plastic and the aluminum alloy material are separated, and the surface of the aluminum alloy is cleaned. Then, through the action of the liquid pump (537) and the filter plate (536), the liquid water circulates to filter impurities. Then the plastic and the aluminum alloy material fall onto the eddy current separator (5331) through the separation pipe (534). The eddy current separator (5331) conveys the plastic and the aluminum alloy material and sorts them by eddy current at the end of the conveyance. At the same time, the solid ring (5336) absorbs the heat of the liquid water. Then the fan (5334) works to blow the heat through the air pipe (5332) and the air holes (5333) onto the moving plastic and aluminum alloy material for drying.
