[0020] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0021] Reference Figure 1-3This utility model embodiment of a toner recycling and reuse device includes a housing 1, with a housing cover 2 hinged to the top of the housing 1. A heating element 3 is fixedly connected to one side of the housing cover 2, which can be achieved by using a resistance wire heater to achieve high-temperature pyrolysis. A material feeding basket 5 is provided inside the housing 1, and a heat exchange box 8 is provided on one side of the housing 1. A heat exchange tube 9 is provided inside the heat exchange box 8. An exhaust pipe 10 is fixedly connected to the side of the housing 1 near the heat exchange box 8. A connecting pipe 11 connected to the top of the heat exchange tube 9 is fixedly connected to the outside of the exhaust pipe 10. The bottom end of the heat exchange tube 9 extends to the outside of the housing 1. A gas supply pipe 12 extending into the housing 1 is fixedly connected to the side of the heat exchange box 8 near the top. The gas supply pipe 12 is located below the material feeding basket 5.

[0022] The recovered carbon powder is placed inside the feeding basket 5. After the feeding basket 5 is located inside the box 1, the box cover 2 is closed. The carbon powder is heated by the heating element 3. At high temperature, the organic pollutants undergo a pyrolysis reaction and are decomposed into small molecules or inorganic substances. After pyrolysis, some of the waste gas inside the box 1 can be transported to the heat exchange tube 9 through the connecting pipe 11. The hot gas is introduced into the heat exchange tube 9 for heat exchange, raising the temperature inside the box 1. The water turns into steam and is transported to the inside of the box 1 through the gas delivery pipe 12. The steam can wash away the inorganic substances remaining in the activated carbon powder. The high temperature and high humidity of the steam effectively wash away the residual substances, restoring the surface of the activated carbon to a better adsorption performance. This realizes the process of carbon powder recovery, drying, and regeneration. At the same time, the heat exchange technology improves the energy efficiency and environmental performance of the device, making it highly practical.

[0023] A support frame 4 is fixedly connected inside the housing 1. The support frame 4 has gaps between its perimeter and the side walls of the housing 1 to ensure smooth steam flow at the top of the discharge basket 5. The discharge basket 5 is inserted into the support frame 4, and a protruding edge 6 is fixedly connected to the top of the discharge basket 5. A filter plate 7 is placed on the top of the discharge basket 5, and the top of the filter plate 7 has a folded edge, which acts as a barrier, forming an enclosed space for filtration. A retaining edge 16 is fixedly connected to the bottom of the filter plate 7, and the retaining edge 16 can be inserted into the top of the discharge basket 5.

[0024] The feeding basket 5 is installed inside the support frame 4 via a movable plug-in connection, facilitating the loading and unloading of the feeding basket 5 and its removal after regeneration. A filter plate 7 is installed on top of the feeding basket 5, through which the recovered toner is filtered before being stored inside the feeding basket 5. This effectively filters the toner, separating large particles of impurities. The filter plate 7 is also connected to the top of the feeding basket 5 via a movable plug-in connection, facilitating removal of the filtered toner and simplifying operation.

[0025] A heater 15 is fixedly connected to the bottom wall of the heat exchange box 8 for heating the inside of the heat exchange box 8 when needed. A temperature sensor can also be installed inside the heat exchange box 8 to work with the heater 15 to heat the water to the required temperature. A water injection pipe 13 is fixedly connected to the top of the heat exchange box 8 for injecting water into the heat exchange box 8. Valves 14 are installed on the outside of the water injection pipe 13, the exhaust pipe 10, and the air supply pipe 12 to control the opening and closing of each pipe.

[0026] Working principle: The recovered carbon powder is placed inside the feeding basket 5. After the feeding basket 5 is located inside the box 1, the box cover 2 is closed. Under the action of the heating element 3, the carbon powder is heated. At high temperature, organic pollutants undergo pyrolysis and are decomposed into small molecules or inorganic substances. After pyrolysis, some of the waste gas inside the box 1 can be transported to the heat exchange tube 9 through the connecting pipe 11. The hot gas is introduced into the heat exchange tube 9 for heat exchange, raising the temperature inside the box 1. After the water is converted into steam, it is transported to the inside of the box 1 through the gas delivery pipe 12. The steam can wash away the inorganic substances remaining in the activated carbon powder. The high temperature and high humidity of the steam effectively wash away the residual substances, restoring the surface of the activated carbon to a better adsorption performance. This realizes the process of carbon powder recovery, drying, and regeneration. At the same time, the heat exchange technology improves the energy efficiency and environmental performance of the device, making it highly practical.

[0027] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
