Description

Technical Field

[0001] This case relates to a continuous waste diaper recycling system, and more specifically, to a recycling system for recycling and processing waste diapers and reusing the processed diapers. Prior Technology

[0002] Disposable diapers are widely used, by infants, the elderly, and those with special needs. Their widespread use in modern society naturally generates a large amount of waste. Statistics show that at least 4 million diapers, approximately 1,300 tons, are generated daily in Taiwan. Currently, diaper disposal methods include incineration and landfill, which not only severely impact the environment but also consume a lot of energy, produce toxic substances, are difficult to decompose, and lead to high carbon dioxide emissions. Furthermore, because diapers absorb excrement and have high moisture content, burning them in incinerators can cause temperature fluctuations, leading to unstable furnace temperatures and cracks in the furnace walls, thus affecting the incinerator's lifespan. Therefore, excessive amounts of discarded diapers are easily rejected by incinerators, posing a significant challenge for governments and businesses.

[0003] With the advent of an aging society and the increasing use of discarded diapers, coupled with the growing global awareness of environmental protection, actively seeking solutions for the disposal of discarded diapers is of paramount importance.

[0004] In view of this, based on the inventor’s many years of experience in manufacturing, developing and designing related products, after detailed design and careful evaluation for the above objectives, the inventor finally came up with a practical new invention. Summary of the Invention

[0005] The main objective of this invention is to provide a continuous waste diaper recycling system, which mainly includes a crushing device, a separating device, and a filtering device.

[0006] The shredding device can receive waste diapers and shred them into multiple diaper units.

[0007] The separation device includes a material cylinder, a spray pipe, and a receiving plate. The material cylinder can be rotated by a drive mechanism. The cylinder wall has a number of holes with a diameter smaller than that of a diaper unit. The spray pipe can inject a water column with a predetermined pressure into the material cylinder. The receiving plate is located below the material cylinder.

[0008] The separation device is connected to the crushing device via a conveyor belt, allowing the diaper units output by the crushing device to enter the material cylinder of the separation device.

[0009] The filtration device is generally shaped like a container, with an inlet and an outlet at each end. Several filter screens are provided between the inlet and outlet. Water from the receiving plate of the separation device can be input into the inlet. The water entering the inlet can pass through several filter screens and then be discharged from the outlet. Simple Explanation of the Diagram

[0010] Figure 1 illustrates a flowchart of the present invention; Figure 2 shows a simplified structural diagram of the present invention. Implementation

[0011] The technical content, features, and effects of the present invention will be clearly presented in the following detailed description of preferred embodiments with reference to the accompanying drawings. Furthermore, before the present invention is described in detail, it should be specifically noted that the accompanying drawings are schematic representations of the basic structure of the present invention. Therefore, only structures or elements relevant to the present invention are shown in these drawings, and the shown structural shapes, dimensions, proportions, or the number and direction of elements are optional designs; this is stated in advance. Additionally, certain terms are defined with consideration of the function in the present invention and may be changed according to actual implementation. Therefore, the terminology used should be defined based on the content of the entire specification and its corresponding functions.

[0012] Please refer to Figure 1, which shows the flowchart of the invention, and Figure 2, which shows the simplified structural diagram of the invention. The continuous waste diaper recycling system of the present invention includes at least a crushing device 10, a separating device 20, and a filtering device 30, wherein:

[0013] A shredding device 10, such as a shearing shredding device, a roller cutting shredding device, or a tearing shredding device, can receive waste diapers 11 and shred the waste diapers 11 into a plurality of diaper units 12. Each diaper unit 12 contains pulp, non-woven fabric, plastic, polymer and excrement. Furthermore, during the shredding process of the waste diapers 11 by the shredding device 10, a disinfectant (such as lime powder) is added by uniform spraying to disinfect and sterilize the diaper unit 12.

[0014] A separating device 20 includes a material cylinder 21, a spray pipe 22, and a receiving plate 23. The material cylinder 21 can be rotated and vibrated by a transmission mechanism, and the receiving plate 23 is located below the material cylinder 21. The cylinder wall of the material cylinder 21 has a plurality of holes 211 with a diameter smaller than that of each diaper unit 12. The spray pipe 22 can inject one or more water jets at a predetermined pressure into the material cylinder 21. The separating device 20 is connected to the crushing device 10 via a conveyor belt A, allowing each diaper unit 12 output from the crushing device 10 to enter the material cylinder 21 of the separating device 20.

[0015] A filtration device 30, generally shaped like a container, has an inlet end 31 and an outlet end 32 at its two ends. Several filter screen layers 33 are provided between the inlet end 31 and the outlet end 32. Water from the receiving tray 23 of the separator 20 can enter through the inlet end 31. The water entering the inlet end 31 passes through the filter screen layers 33 and is discharged through the outlet end 32. Furthermore, the water discharged from the outlet end 32 can be recycled and reused through the spray pipe 22 of the separator 20.

[0016] According to the structure of the pulverizing device 10, separating device 20, and filtering device 30 of the present invention, the pulverizing device 10 can receive waste diapers 11 and pulverize them into multiple diaper units 12. These diaper units 12 are sterilized by the action of lime powder. The diaper units 12 are then output by conveyor belt A and fed into the material cylinder 21 of the separating device 20. Through the rotation, tumbling, vibration of the material cylinder 21 and the continuous injection of water through the spray pipe 23, the pulp, non-woven fabric, plastic, and polymer contained in each diaper unit 12 are decomposed. The pulp and polymer dissolve in the water and flow through the holes 211 in the cylinder wall of the material cylinder 21 to the receiving tray 23. The remaining non-woven fabric and plastic, due to their larger volume than the holes 211, remain inside the material cylinder 21. The plastic remaining inside the material cylinder 21 can be removed for subsequent granulation, while the non-woven fabric can be recycled using a single-shaft shredding and recycling machine. When the pulp and polymer are dissolved in water and flow through the holes 211 in the barrel wall of the feed cylinder 21 to the receiving tray 23, they can be fed into the water inlet 31 of the filter device 30. The pulp passes through several filter screen layers 33, which trap it on the surface of each filter screen layer 33, allowing it to be removed for secondary processing. The remaining water and dissolved polymer are discharged from the water outlet 32. Furthermore, the water discharged from the water outlet 32 ​​can be recycled and reused through the spray pipe 22 of the separator 20.

[0017] In this embodiment, the waste diaper 11 is crushed into a plurality of diaper units 12, and the pulp, non-woven fabric, plastic and polymer contained in each diaper unit 12 are separated one by one and taken out for recycling. Through the continuous waste diaper recycling system of the present invention, the thorny environmental problems caused by waste diapers are completely solved, the situation of waste diapers hindering environmental development is reversed, and a win-win technology model of circular economy is created.

[0018] In summary, according to the design of the present invention, a recycling system for collecting and processing waste diapers and reusing the processed diapers can be provided. However, the foregoing structural description is merely to explain the preferred embodiment of the present invention and is not intended to limit the structure of the invention. Therefore, any equivalent modifications or alterations made under the same spirit should still be included within the scope of protection of the present invention. As described above, this application has many advantages and significant practical characteristics. Furthermore, the technical means and structural features employed are indeed developed by the inventor of this application, and the structure is unprecedented in the market. Therefore, this application meets the requirements for a patent, and we hereby file this application in accordance with the law, and earnestly request the granting of patent rights.
