Description

Technical Field

[0001] This utility model relates to the field of waste recycling technology, and in particular to a printing waste recycling and separation device. Background Technology

[0002] The printing industry generates a large amount of waste materials, including paper, plastic film, and metal binding materials, with various types of inks such as water-based and solvent-based inks adhering to their surfaces. Currently, traditional methods of printing waste disposal have several drawbacks: First, incineration produces harmful gases such as dioxins from the ink, polluting the atmosphere. Second, landfill disposal not only occupies significant land resources, but heavy metals and organic components from the ink can also seep into the soil and groundwater, causing environmental pollution. Third, most existing waste recycling devices only crush and simply sort the waste materials, lacking effective techniques for separating and recycling ink, resulting in ink being mixed with the materials, which reduces the quality of recycled materials and wastes ink resources.

[0003] In the prior art, patent CN212167661U discloses a waste recycling device for printing presses, relating to the field of recycling device technology. Addressing the problem of poor performance in existing waste recycling devices, the following solution is proposed: It includes a recycling box, with a processing chamber and a recycling chamber sequentially arranged from top to bottom inside the recycling box.

A vertically arranged rotating shaft is rotatably connected inside the processing chamber via bearings. Multiple horizontally arranged cutting blades are welded vertically to both sides of the rotating shaft. A horizontally arranged pressure plate is slidably connected inside the processing chamber. This utility model can conveniently collect printing waste, cut and compress the collected printing waste, and facilitate user collection and use of the processed printing waste. It has a large storage capacity, is easy to use, and has high performance.

[0004] Patent CN210733587U discloses a green printing waste recycling device, including an ink storage box, a waste recycling box, a reuse mechanism, a recycling main pipe, and a stirring mechanism. The waste recycling box is fixedly installed on one side of the ink storage box, and a reuse mechanism is installed between the waste recycling box and the ink storage box.

[0024] Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0026] Reference Figure 1-4As shown, this utility model discloses a printing waste recycling and separation device, comprising a crushing zone 1, a discharge zone 2, an ink recovery zone 3, a waste drying zone 4, and a waste separation zone 5 installed sequentially. The crushing zone 1 includes a crushed material collection trough 10, on which a feeding bin 11 is installed. A crushing device 12 is fixed to the bottom of the feeding bin 11. Printing waste is fed from the top of the feeding bin 11 and crushed into smaller pieces by the crushing device 12 for easier subsequent processing. The discharge zone 2 includes a discharge inclined channel 20, which connects the crushed material collection trough 10 and the ink recovery zone 3. The waste is discharged by sliding down under its own gravity. The ink recovery zone 3 includes a cleaning agent bin 32, a first conveying pipe 30, and a spray cleaning chamber. The cleaning agent in the cleaning agent tank 32 is pumped from the first conveying pipe 30 to the spray cleaning chamber and then flows into the waste liquid collection tank 33. After the waste in the spray cleaning chamber is sprayed and cleaned by the cleaning agent, the ink on the waste is dissolved and separated from the substrate, and flows into the waste liquid collection tank 33. The waste drying zone 4 includes drying the cleaned waste and conveying it to the waste separation zone 5. After the waste is dried, it is easy to separate light waste and heavy waste by wind. The waste separation zone 5 is equipped with a wind separator 50, a light waste collection tank 54 and a heavy waste collection tank 55. The upper end of the wind separator 50 is connected to the light waste collection tank 54 through the second conveying pipe 51. The heavy waste collection tank 55 is located in front of and below the wind separator 50.

[0027] Furthermore, the top opening of the feed hopper 11 is funnel-shaped, facilitating quick loading of printing waste by operators. Additionally, the crushing equipment 12 is a twin-shaft crusher, with several blades staggered on each of its two shafts. The blades are made of high-strength, wear-resistant alloy steel. The motor of the twin-shaft crusher, after speed reduction, drives the two shafts to rotate in opposite directions, causing the blades to shear and crush the printing waste, effectively crushing printing waste of various shapes and materials.

[0028] Furthermore, a sliding door panel 13 is installed at one end of the crushed material collection trough 10. A height sensor 111 is installed inside the crushed material collection trough 10. The start and stop actions of the sliding door panel 13 are linked to the controller. The controller receives the signal from the height sensor 111. One end of the sliding door panel 13 is connected to the discharge inclined channel 20. When the height sensor 111 detects that the height of the crushed waste reaches the value set by the controller, the sliding door panel 13 is opened, allowing the crushed material to be discharged and enter the next ink recycling process. In addition, the inclination angle of the discharge inclined channel 20 is 30-45 degrees, ensuring that the waste can smoothly slide down to the discharge area 2 by gravity. Moreover, the surface of the discharge inclined channel 20 is smooth, which can reduce the risk of waste jamming.

[0029] Furthermore, several nozzles 31 are installed inside the spray cleaning chamber. Each nozzle 31 is connected to a first delivery pipe 30, which is connected to a pump and valves. When the pump is started and the valves are opened, the nozzles 31 spray cleaning agent, performing high-pressure spray cleaning on the crushed waste material to promote ink removal from the substrate surface. The cleaning agent is generally a water-based, pH-neutral solvent, which can effectively dissolve the ink on the waste material. A waste liquid outlet 35 is machined at the end of the spray cleaning chamber to discharge the ink-containing cleaning agent into a waste liquid collection tank 33. The waste liquid collection tank 33 is located outside the spray cleaning chamber and is equipped with a liquid level sensor 34. When the liquid level reaches a certain value, it is centrally discharged.

[0030] Furthermore, a hot air drying chamber 40 is installed in the waste drying zone 4 to quickly dry the cleaned waste, so that the waste separation zone 5 can efficiently separate the substrate. A temperature sensor is installed inside the hot air drying chamber 40 to monitor the temperature inside the chamber in real time and feed the data back to the controller. Based on the waste material and drying requirements, the controller automatically adjusts the hot air temperature and airflow to prevent damage to the waste substrate due to excessive temperature.

[0031] Furthermore, the air separator 50 is connected to the hot air drying box 40 through the dry waste inlet 53. The air separator 50 includes a fan 52, and an adjustable damper (not shown in the figure) is installed at the air inlet of the second conveying pipe 51. The opening degree of the damper is related to the rotational speed of the fan 52. The waste separation zone 5 uses air separation to separate waste. Waste from the hot air drying box 40 enters the air separator 50 through the dry waste inlet 53. The fan 52 inside the air separator 50 generates horizontal or inclined airflow. By utilizing the difference in the movement trajectory of waste of different masses in the airflow, light waste (such as paper fibers and dust) is separated from heavy waste (such as plastic sheets, metal blocks, and glass fragments). Light waste is carried to its outlet by the airflow through the second conveying pipe 51 and falls into its light waste collection tank 54. Heavy waste settles to the bottom heavy waste collection tank 55 due to gravity for subsequent processing.

[0032] Working principle: First, the printing waste is fed into the crushing equipment 12 from the top of the feeding hopper 11. After the crushing equipment 12 crushes the waste, it enters the ink recovery area 3 through the inclined discharge channel 20. The nozzle 31 on the spray cleaning chamber is turned on and sprays cleaning agent to separate the ink from the substrate. The cleaning agent containing ink flows into the waste liquid collection tank 33 through the waste liquid outlet 35. The cleaned waste enters the hot air drying box 40 for drying treatment. The dried waste enters the wind separation area, where different materials of substrate are separated by wind. Each substrate is recycled to the corresponding light waste collection tank 54 and heavy waste collection tank 55.

[0033] In this utility model device, the assembly and coordination of various components are involved. The crushing equipment 12, pump, valve, nozzle 31, cleaning agent, hot air drying box 40, fan 52 and various sensors and controllers are existing technologies or materials. The relevant technical personnel can directly purchase or order them from the market according to the required product models and specifications.

[0034] All electrical components mentioned in the text are connected to an external main controller and 220V AC mains power or industrial power. The main controller can be a conventional known device such as a computer that plays a control role.

[0035] The above description is merely a preferred embodiment of this utility model, and common knowledge regarding specific structures and characteristics is not described in detail here. It is obvious to those skilled in the art that this utility model is not limited to the details of the above embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
