Detailed Description

The invention is described in further detail below with reference to the accompanying examples.

This example provides a method for recycling chalcogenide glass scrap. Referring to fig. 1, the method for recycling the chalcogenide glass scrap according to the embodiment includes the following steps S1 to S10:

step S1, collecting chalcogenide glass leftover materials 1 correspondingly generated in different process stages in the process of processing the same chalcogenide glass; considering that chalcogenide glass is an inorganic compound with similar composition elements but different composition proportions, the obtained chalcogenide glass leftover materials can be recycled for multiple times only by ensuring that the obtained chalcogenide glass leftover materials have the same components and composition proportions in recycling, and the composition proportions are ensured to be unchanged; therefore, in this embodiment, all collected chalcogenide glass scraps are scraps generated in the same chalcogenide glass processing process, so as to ensure that the compositions of all collected scraps are the same and the proportions of the corresponding compositions are the same;

it should be noted that the collected chalcogenide glass leftover materials collected by the traditional chalcogenide glass leftover material recycling method are not completely directed to the same chalcogenide glass preparation process, that is, the collected chalcogenide glass leftover materials are possibly the mixture of the leftover materials generated by preparing chalcogenide glass A by using a material component X and the leftover materials generated by preparing chalcogenide glass B by using a material component Y, so that the composition components of all the leftover materials collected by the traditional method are different, and even if the composition components are the same, the composition proportions of the same composition components are also different, namely completely different chalcogenide glass leftover materials are collected, which very easily causes that the treatment measures adopted in the recycling process cannot be applied to each type of leftover materials, causes the inconsistent quality of the chalcogenide glass leftover materials obtained in the early stage and the final recycling process, and greatly reduces the quality of the recycled chalcogenide glass, serious adverse effects are caused to the subsequent preparation of chalcogenide glass by utilizing recycled chalcogenide glass leftover materials;

step S2, all collected chalcogenide glass leftover materials 1 are loaded into a stainless steel container 3 which can be overturned along with a rotating shaft 21 of a driving motor 2, so that the inner layer and the outer layer are isolated; the stainless steel container 3 has an inner layer gauze 31, an outer layer gauze 32 annularly arranged outside the inner layer gauze 31, and a container cover 33 for tightly covering the opening of the stainless steel container, wherein the container cover 33 also has the inner layer gauze and the outer layer gauze. The aperture of the outer layer gauze 32 of the stainless steel container 3 is smaller than that of the inner layer gauze 31, the outer layer gauze 32 and the inner layer gauze 31 both have rigidity, the inner layer gauze 31 is in a closed shape capable of wrapping all chalcogenide glass leftover materials 1, the container cover 33 is provided with gauze, and all collected chalcogenide glass leftover materials 1 are filled in the inner side of the inner layer gauze 31;

for example, the aperture shapes of the inner layer gauze 31 and the outer layer gauze 32 may be any shapes, in this embodiment, the aperture shapes of the inner layer gauze 31 and the outer layer gauze 32 are preferably square, and the aperture of the inner layer gauze 31 is 4mm by 4mm, and the aperture of the outer layer gauze 32 is 2mm by 2 mm; because the outer layer gauze 32 and the inner layer gauze 31 both have rigidity, and have supporting structures and are rigidly connected, the inner layer gauze and the outer layer gauze can be supported in the stainless steel container and synchronously rotate, and further all the chalcogenide glass leftover materials 1 in the inner layer gauze 31 can be effectively turned over along with the overturning of the stainless steel container 3;

in the embodiment, as the aperture of the inner layer gauze 31 is larger than that of the outer layer gauze 32, in the turning process, the chalcogenide glass leftover materials with smaller particle sizes in all chalcogenide glass leftover materials 1 enter the space between the inner layer gauze 31 and the outer layer gauze 32 after being filtered by the aperture of the inner layer gauze 31, and the chalcogenide glass leftover materials with smaller particle sizes entering the space between the inner layer gauze 31 and the outer layer gauze 32 can fall outside the outer layer gauze 32 again after being filtered by the aperture of the outer layer gauze 32, so that materials such as fine polishing sand and the like generated in the processing process are effectively separated, and the multiple filtering effect for all collected chalcogenide glass leftover materials is realized;

step S3, putting the stainless steel container 3 with the chalcogenide glass leftover materials into an ultrasonic cleaning machine 4, injecting a powerful debonding agent into the stainless steel container 3 in a ventilation environment, mixing the powerful debonding agent with the chalcogenide glass leftover materials, and then tightly covering a cover 41 of the ultrasonic cleaning machine 4; wherein the powerful debonder is a polar debonder, such as toluene, and the powerful debonder is used for removing organic binders on the chalcogenide glass scrap contained in the stainless steel container 3; the bottom of the ultrasonic cleaning machine 4 is provided with a material containing groove 5, the upper port of the material containing groove 5 is covered with a small-aperture filter screen 6, the small-aperture filter screen 6 is positioned below the stainless steel container 3, and the aperture of the small-aperture filter screen 6 is smaller than that of the outer layer gauze 32;

a material containing groove 5 is arranged below the stainless steel container 3, and the upper port of the material containing groove 5 is covered with a small-aperture filter screen 6 with the aperture smaller than that of the outer layer gauze 32, so that leftover materials with smaller particle size in chalcogenide glass leftover materials falling to the outer side of the outer layer gauze 32 can enter the material containing groove 5 through the small-aperture filter screen 6;

step S4, starting cleaning programs of the driving motor 2 and the ultrasonic cleaning machine 4, and enabling the driving motor 2 to rotate according to a first preset driving procedure, so that the stainless steel container 3 is turned over along with the rotating shaft 21 of the driving motor 2 in the ultrasonic cleaning machine 4, and the turning is maintained for a first preset turning time of 60 min; in this embodiment, the first predetermined driving process includes steps b 1-b 6:

step b1, the driving motor is started to rotate in the positive direction, and the first positive acceleration is 100R/min²Accelerating the rotating speed of the rotating shaft to a first forward target rotating speed value of 100R/min; wherein, the forward rotation is clockwise rotation of the driving motor; correspondingly, the subsequent reverse rotation means that the driving motor rotates anticlockwise;

step b2, keeping the driving motor rotating at the first forward direction target rotating speed value of 100R/min for a first maintenance time period of 1 min; the chalcogenide glass leftover materials in the stainless steel container 3 can be continuously rolled along with the rotation of the driving motor, the relative flow velocity between the solvent or the cleaning agent and the chalcogenide glass leftover materials is increased, and the chalcogenide glass leftover materials are efficiently washed;

step b3, enabling the driving motor to decelerate the rotating speed of the driving motor from the first forward target rotating speed value 100R/min to zero at a first forward deceleration of 100R/min2, and maintaining the driving motor to pause for a first pause duration of 0.5min at the zero rotating speed; by enabling the driving motor to execute the step b3, the chalcogenide glass leftover materials in the current state can be effectively soaked in the powerful debonding agent, and the driving motor can be protected;

step b4, the driving motor is started to rotate reversely to accelerate at a first reverse acceleration of 100R/min²Accelerating the rotating speed of the rotating shaft to a first reverse target rotating speed value of 100R/min;

step b5, enabling the driving motor to maintain rotating at the first reverse target rotating speed value of 100R/min for a second maintenance duration of 1 min;

step b6, enabling the driving motor to decelerate the rotating speed of the driving motor from the first reverse target rotating speed value 100R/min to zero by the first reverse deceleration 100R/min2, and maintaining the driving motor to pause for a second pause duration of 0.5min at the zero rotating speed;

step S5, closing the cleaning program of the driving motor 2 and the ultrasonic cleaning machine 4, pumping away the powerful debonding agent in the ultrasonic cleaning machine 4, and injecting absolute ethyl alcohol into the ultrasonic cleaning machine 4; after the powerful debonder in the ultrasonic cleaning machine 4 is pumped away, the organic binder is not attached to the chalcogenide glass leftover material in the ultrasonic cleaning machine 4, but inorganic matters can still be attached to the chalcogenide glass leftover material; the absolute ethyl alcohol injected here has the effect of removing inorganic substances that may adhere to the chalcogenide glass scrap;
