Description

Technical Field

[0001] The present invention relates to a continuous used diaper collection system, and more particularly to a collection system for collecting, processing used diapers, and reusing the processed diapers.

Background Art

[0002] Disposable paper diapers are widely popular, and many people such as infants, the elderly, and users who require special support use them. In modern society, disposable diapers are widely used, resulting in a large amount of waste. According to statistics, at least 4 million pieces, approximately 1,300 tons of used diapers are discharged in the country every day. However, the current methods for treating used diapers are only two types: incineration or landfill, which not only have a serious impact on the environment but also cause problems such as high energy consumption, generation of toxic substances, difficulty in decomposition, and high carbon dioxide emissions. Furthermore, diapers that have absorbed excrement contain a high amount of moisture. When they are put into an incinerator, the temperature inside the furnace is likely to fluctuate, and cracks may occur in the furnace wall due to the temperature instability, which may shorten the life of the incinerator. Therefore, if the amount of used diapers to be discarded is too large, the incinerator may refuse to process them, which becomes a serious problem for the government and related operators.

[0003] In view of the drawbacks of the above-known structure, the present invention notices its incomplete points, conducts thorough research, and aims to overcome them.

Summary of the Invention

[0008] To fully understand the purpose, features, and effects of the present invention, the present invention will be described in detail below based on the following specific embodiments together with the accompanying drawings. Please refer to FIGS. 1 to 2. As shown in the figures, the present invention combines FIGS. 1 and 2 with specific embodiments. Furthermore, it is explicitly stated in advance that the shapes, dimensions, ratios, number of parts, directions, etc. of the structures shown in the drawings are only examples of optional designs. In addition, some terms are defined in consideration of the functions in the present invention and may be changed according to the actual embodiments. Therefore, the terms used should be defined based on the content of the entire specification and its functions.

[0009] Please refer to the flowchart of the present invention shown in FIG. 1 and the structural schematic diagram of the present invention shown in FIG. 2. The continuous used diaper recycling system of the present invention includes at least a pulverizing device 10, a separating device 20, and a filtering device 30, and its configuration is as follows. One pulverizing device 10 refers to a shearing pulverizing device, a roller cutting pulverizing device, a tearing pulverizing device, etc. The pulverizing device 10 can receive used diapers 11 and pulverize them into a plurality of small diaper units 12. Each diaper unit 12 contains pulp, non-woven fabric, plastic, polymer, and excrement. Also, during the process of the pulverizing device 10 pulverizing the used diapers 11, the diaper units 12 are disinfected and sterilized by evenly spraying a disinfectant (e.g., lime powder).

[0010] One separating device 20 includes a supply cylinder 21, an injection pipeline 22, and a tray 23. The supply cylinder 21 can be rotated or vibrated by a driving mechanism. The tray 23 is disposed below the supply cylinder 21. A plurality of small holes 211 smaller than the holes of each diaper unit 12 are provided on the cylinder wall of the supply cylinder 21. The injection pipeline 22 can inject one or a plurality of water columns into the supply cylinder 21 at a predetermined pressure. The separating device 20 is in cooperation with the pulverizing device 10 via a conveyor belt A, and each diaper unit 12 output from the pulverizing device 10 can be fed into the supply cylinder 21 of the separating device 20.

[0011] The filtering device 30 generally presents a container shape, and a water supply end 31 and a drain end 32 are respectively provided at both ends thereof. A plurality of filter layers 33 are disposed between the water supply end 31 and the drain end 32. The water supply end 31 can receive the water liquid discharged from the tray 23 of the separating device 20. The water liquid flowing into the water supply end 31 is discharged from the drain end 32 after passing through the plurality of filter layers 33. In addition, the water liquid discharged from the drain end 32 is recovered by the water spray pipeline 22 of the separating device 20 and reused. The water supply end 31 of the above-mentioned filtering device 30 is pivotally attached to the tray 23 of the separating device 20 via a pipeline.

[0012] According to the structures of the above-mentioned pulverizing device 10, separating device 20, and filtering device 30, the pulverizing device 10 can receive the used diaper 11 and pulverize it into a plurality of small diaper units 12. The diaper unit 12 is subjected to the action of lime powder to obtain a disinfection and sterilization effect. At this point, the diaper unit 12 is discharged by the conveyor A and sent into the cylindrical container 21 of the separating device 20. Due to the rotation, stirring, vibration of the supply cylinder 21 and the continuous water injection by the water spray pipeline 22, the pulp, non-woven fabric, plastic, and polymer contained in the diaper unit 12 are decomposed. In this process, the pulp and polymer dissolve in water and flow into the tray 23 through the small holes 211 provided on the wall surface of the supply cylinder 21. On the other hand, since the non-woven fabric and plastic are larger than the small holes 211, they remain in the supply cylinder 21. The plastic remaining in the container is recovered and used for subsequent pelletizing treatment, and the non-woven fabric is reused by a single-shaft shredder integrated recycling machine.

[0013] The pulp and the polymer are dissolved in water. After flowing into the tray 23 through the holes 211 of the supply cylinder 21, they are taken in from the water supply end 31 of the filtering device 30 and filtered by a plurality of filter layers 33. The pulp accumulates on the surface of the filter layer 33 and is later recovered for secondary processing. On the other hand, the remaining aqueous solution and the polymer dissolved in water are discharged from the drainage end 32. Also, the aqueous solution discharged from the drainage end 32 is recovered by the water spray pipeline 22 of the separation device 20 and reused. In this embodiment, the used diaper 11 is crushed into a plurality of small diaper units 12, and the pulp, non-woven fabric, plastic, and polymer contained in each unit are sequentially separated, recovered, and reused. Through the diaper recycling system of the present invention, the environmental problems caused by troublesome used diapers can be fundamentally solved, the situation of used diapers that hinder environmental development can be refreshed, and a win-win technology model for realizing a circular economy can be constructed.

[0014] From the above description, it can be seen that the design of the present invention can provide a recycling system for recovering and treating used diapers and recycling the treated diapers. However, the above-described configuration content is for explaining the preferred embodiments of the present invention and does not limit the structure of the present invention. Therefore, equivalent modifications and changes based on the spirit of the present invention should also be included in the protection scope of the present invention. From the above description, it is obvious that the present invention has many advantages and high practicality. Its technical means and structural features are exactly those developed by the creator of the present invention and have novelty that has not existed in the market so far. Therefore, the present invention is confident that it meets the patent requirements, applies for a patent based on the law, and requests the grant of a patent right.
