The comparative document is a method of separating the waste acetate fiber tow from the paper of the filter tip by chemical means. This method has many process flows, high processing costs, and uses chemical solvents in industry, such as alcohols, ethers, and aromatic hydrocarbons for deesterification, and acetone for melting solvent, which pollutes the environment and poses safety risks. Utility Model Content

[0003] The technical problem to be solved by the utility model is to solve the problems that the existing cigarette filter tip recycling method uses a chemical method, has high processing costs, pollutes the environment and endangers the personal safety of workers.

[0004] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0005] A waste cigarette filter tip recycling and processing device, comprising a cutter 100, a conveyor 200, a mesh drum 300, a heating separation and exhaust device 400 and a particle vibration screen 500;

[0006] One end of the conveyor 200 is located at the outlet of the cutting machine 100, and the other end is located at the inlet of the mesh drum 300; the mesh drum 300 is in the heating separation and exhaust device 400, tilted and suspended in the air, the inlet of the mesh drum 300 is high, the outlet is low, and it can rotate relative to the heating separation and exhaust device 400; the heating separation and exhaust device 400 heats the waste cigarette filter tip cut in the mesh drum 300, shrinks the tow into tow particles and separates it from the wrapping paper, and extracts and collects the heated and vaporized triacetin in the tow; the particle vibrating screen 500 is located at the outlet of the mesh drum 300, receives the tow particles and the wrapping paper, and screens the tow particles;

[0007] Among them, the heating separation exhaust device 400 includes a heating cylinder 410, a drainage air pipe 420, a condensing device 430 and an induced draft fan device 440; the mesh drum 300 is located in the heating cylinder 410, one end of the drainage air pipe 420 is connected to the heating cylinder 410, and the other end is connected to the condensing device 430, and the induced draft fan device 440 is connected to the condensing device 430 to form an exhaust condensation channel.

[0008] Advantages: The utility model uses a physical method to separate the tow from the packaging paper, without chemical pollution, and the operation is simpler. The operator does not need to master chemical knowledge, and it is more universal and safe. Compared with the reference document, the utility model does not need to soak the discarded cigarette filter tip. In the reference document, the soaking time of the filter tip is 1 hour, and there is no need to remove the deesterification solvent in the soaked filter tip, which saves two process flows. In the reference document, it is also necessary to put the soaked filter tip into a chemical solvent to melt the tow, so as to obtain emulsified tow and non-melting paper, and then separate the emulsified tow from the non-melting paper by filtering or centrifugation. In this step, the utility model has separated the tow from the paper by a particle vibrating screen, while the reference document also needs to evaporate the emulsified tow. Because the emulsified tow contains chemical solvents, the chemical solvents are evaporated and recovered to obtain solidified tows. Therefore, compared with the reference document, the utility model saves another evaporation process. The mesh drum and the heating separation and exhaust device cooperate with each other to simultaneously complete the separation of the tow from the packaging paper and the collection of acetic acid glyceride.

[0018] See also Figure 1 As shown, the utility model provides a waste cigarette filter tip recycling and processing equipment, including a cutter 100, a conveyor 200, a mesh drum 300, a heating separation and exhaust device 400 and a particle vibration screen 500.

[0019] One end of the conveyor 200 is located at the exit of the cutter 100, and the other end is located at the entrance of the mesh drum 300. The mesh drum 300 is tilted and suspended in the heating and separation exhaust device 400, with the entrance of the mesh drum 300 being high and the exit being low, and can rotate relative to the heating and separation exhaust device 400. The heating and separation exhaust device 400 heats the waste cigarette filter tip cut in the mesh drum 300, shrinks the tow into tow particles and separates it from the wrapping paper, and extracts and collects the heated and vaporized triacetin in the tow. The particle vibrating screen 500 is located at the exit of the mesh drum 300, receives the tow particles and the wrapping paper, and screens the tow particles.

[0020] In one embodiment of the utility model, the cutter 100 cuts the discarded cigarette filter tip to form multiple filter tips with a length of 0.5-5 cm. In this embodiment, the discarded cigarette filter tip is a discarded filter tip in the finished filter tip manufacturing process in a cigarette manufacturing plant. In addition, in this embodiment, the cutter 100 is a commercially available cutter. The conveyor 200 is a commonly used conveyor 200 in a factory assembly line, and the cut filter tip is sent to the mesh drum 300 through the conveyor 200.

[0021] In one embodiment of the utility model, the mesh drum 300 includes a mesh drum body 310, a front fixed follower 320 and a rear fixed active member 330. Among them, an annular slide rail 311 is provided at the end of the mesh drum body 310 near the inlet, and an annular rack 312 is provided at the end of the mesh drum body 310 near the outlet. The bottom of the front fixed follower 320 is fixed to the ground, and a pulley is provided on the top, and the pulley is movably connected with the annular slide rail 311. The bottom of the rear fixed active member 330 is fixed to the ground, and a driving motor is provided on the top, and a driving gear is coaxially fixed on the output shaft of the driving motor, and the driving gear is meshed with the annular rack 312. When the mesh drum 300 is working, the driving motor is started, the driving gear is meshed with the annular rack 312, and the pulley rolls on the annular slide rail 311, driving the mesh drum body 310 to rotate. In this embodiment, the length of the mesh drum 300 is controlled at 1m, the rotation speed is 14-40r / min, and the filter tip stays in the drum for 5-10min after being cut. The function of the mesh drum 300 is to allow the cut filter tip to be heated quickly and evenly, and the mesh setting allows the gaseous triacetin to be sucked away by the heating separation and exhaust device 400. In this embodiment, the mesh drum 300 is improved from a drum screen on the market.

[0022] In one embodiment of the present invention, the heating separation and exhaust device 400 includes a heating cylinder 410, a drainage air pipe 420, a condensing device 430 and an induced draft fan device 440. The mesh drum 300 is located in the heating cylinder 410, one end of the drainage air pipe 420 is connected to the heating cylinder 410, and the other end is connected to the condensing device 430, and the induced draft fan device 440 is connected to the condensing device 430 to form an exhaust condensation channel.

[0023] The heating cylinder 410 is formed by enclosing a plurality of heating plates, the heat source is infrared heating, resistance wire or ceramic electric heating, preferably ceramic electric heating, and the mesh drum body 310 is suspended in the heating cylinder 410. The condensation device 430 includes a condensation collection container 431, a condenser and a circulating water pump 432. The condenser is located in the condensation collection container 431, and the circulating water pump 432 is connected to the condenser for water circulation to maintain the temperature in the condensation collection container 431. The drainage air pipe 420 and the induced draft fan device 440 are respectively located on mutually perpendicular sides of the condensation collection container 431 and are connected to the condensation collection container 431. The condensation collection container 431 is a rectangular parallelepiped, and the gaseous triacetin forms a turning airflow in the condensation collection container 431, which increases the residence time of the gaseous triacetin in the condensation collection container 431 and improves the condensation effect.

[0024] When the heating separation and exhaust device 400 is working, the filaments in the filter tip shrink due to the heat, and when shrinking to a certain density, they become filament particles, and are separated from the wrapping paper of the filter tip. At the same time, the vaporized triacetin produced by the heating of the filaments is sucked away by the induced draft fan device 440 along the exhaust condensation channel, and when passing through the condensation device 430, it is condensed and solidified on the inner wall of the condensation collection container 431 by the condenser. In this embodiment, the heating cylinder 410 is heated to 200-240 degrees Celsius, and the wind speed of the induced draft fan device 440 is 3-5 m / s.

[0025] In one embodiment of the present invention, the particle vibrating screen 500 separates the received tow particles from the packaging paper and screens the tow particles. The particle vibrating screen 500 is a conventional electric vibrating screen on the market.
