[0029] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0030] Paper scraps are generated during the processing and production of paper products. Excessive concentration of paper scraps will not only affect the health of operators, but also seriously affect the quality of paper products.

[0031] The paper scraps here include not only scraps and various paper scraps ranging from large pieces to extremely small particles, but also paper hair (fine fiber filaments) and paper dust (extremely small paper fiber particles suspended in the air or dust generated during paper processing (such as cutting and polishing)).

[0032] If the paper scraps generated during paper processing and production are directly discharged outside the factory, a large amount of paper scraps will accumulate and block the sewer, which will also cause environmental pollution. In some related technologies, paper scraps are collected using a storage bag, which is prone to blockage of the storage bag, affecting the collection effect of paper scraps. At the same time, the storage bag needs to be replaced and cleaned frequently, which will also cause sewer blockage when cleaning the storage bag.

[0033] In order to improve the production environment, increase production efficiency and reduce production costs, the present invention provides a paper scrap collection and recycling device, which is suitable for recycling paper scraps during paper production and processing. It is easy to operate and can complete paper scrap recycling more efficiently and environmentally friendly.

[0034] Figure 1 and Figure 2 It is a schematic structural diagram of some embodiments of the paper scrap collection and recovery device according to the present utility model.

[0035] refer to Figure 1 and Figure 2 In some embodiments, the paper scrap collection and recovery device includes a first box body 1, a second box body 2 and a cover plate 3.

[0036] The first box body 1 has an open end, and water is pre-placed in the first box body 1 .

[0037] The second box body 2 is arranged in the first box body 1 ; a plurality of through holes 21 are arranged on the upper part of the side wall of the second box body 2 , and the through holes 21 fluidly connect the second box body 2 and the first box body 1 .

[0038] The cover plate 3 is arranged at the open end of the first box body 1 to cover the second box body 2 in the first box body 1; the cover plate 3 is provided with an inlet 31 and an outlet 32, the inlet 31 is configured to introduce gas containing paper scraps into the second box body 2, and the outlet 32 ​​is configured to lead the gas in the second box body 2 out.

[0039] In the above embodiment, water is pre-placed in the first box body 1, the second box body 2 is arranged in the first box body 1, and water is also pre-placed in the second box body 2. A plurality of through holes 21 are provided on the upper part of the side wall of the second box body 2. The through holes 21 fluidly connect the first box body 1 and the second box body 2, so that the water surface in the first box body 1 is flush with the water surface in the second box body 2.

[0040] The paper scraps generated during the paper product production and processing are discharged through the air flow, and the gas containing the paper scraps is sent into the second box body 2 through the inlet 31. The gas impacts the water in the second box body 2. Since particles such as paper scraps have the characteristics of being dry and easy to float, the paper scraps in the gas will be integrated into the water, thereby improving the recycling effect of the paper scraps. The filtered gas is discharged through the outlet, which can avoid pollution to the environment; after being soaked in the water in the second box body 2, the paper scraps are turned into paper mud and precipitated at the bottom of the second box body 2. When the paper mud in the second box body 2 accumulates to a certain amount, the cover 3 is opened, the second box body 2 is taken out, and the paper mud in the second box body 2 is dried. The dried paper mud can be recycled like the waste paper generated in the production process, which can reduce costs and improve recycling efficiency.

[0041] A plurality of through holes 21 are provided on the upper part of the side wall of the second box body 2. The through holes 21 fluidly connect the second box body 2 and the first box body 1, which is conducive to the water in the first box body 1 entering the second box body 2 through the through holes 21. When the second box body 2 is extracted, the relatively clean water in the upper layer of the second box body 2 can be discharged from the second box body 2 through the through holes 21, while the paper mud is deposited at the bottom of the second box body 2, thereby improving the separation effect of water and paper mud, and being able to extract and recover paper mud more efficiently.

[0042] The paper scrap collection and recycling device provided by the utility model is easy to operate and can complete paper scrap recycling in a more efficient and environmentally friendly manner.

[0043] In some embodiments, the paper scrap collection and recovery device also includes a fan, which is configured to suck the gas containing paper scraps in the paper production plant. The gas containing paper scraps sucked by the fan is sent into the second box body 2 through the inlet 31 on the cover plate 3, and the paper scraps are immersed in the water in the second box body 2.

[0044] In some embodiments, in order to ensure that the collection and drying of recycled paper scraps are carried out simultaneously, multiple second boxes 2 can be prepared. Some second boxes 2 collect paper scraps in the first box 1, and other second boxes 2 are taken out of the first box 1 after collecting paper mud and dried, so as to ensure efficient operation of paper scrap collection and recycling.

[0045] In some embodiments, the inlet 31 is disposed at the first end of the cover plate 3 , and the outlet 32 ​​is disposed at the second end of the cover plate 3 . The first end and the second end of the cover plate 3 are two ends far away from each other.

[0046] In some embodiments, a handle is provided on the cover plate 3 , and the cover plate 3 can be lifted by the handle to facilitate installation and removal of the cover plate 3 .

[0047] In some embodiments, the paper scrap collection and recovery device further includes a filter screen 4 , which is disposed in the second box body 2 and between the inlet 31 and the outlet 32 ​​.

[0048] In order to ensure that the gas flowing out of the outlet 32 ​​is cleaner and improve the purification and dust removal effect, water is pre-placed in the first box body 1, and the paper scraps are wetted by a wet method. A filter screen 4 is arranged between the inlet 31 and the outlet 32, and the lower end of the filter screen 4 is immersed in a water pool. The surface tension of water is used to exert a capillary effect on the filter screen 4, thereby increasing the humidity of the filter screen 4 and forming a water film on the surface of the filter screen 4, thereby improving the paper scrap filtering effect.

[0049] In some embodiments, the paper scrap collection and recovery device further includes a mounting frame 5 , which is disposed on the second box body 2 and supports the filter screen 4 .

[0050] In the above embodiment, the mounting frame 5 is an inverted U-shaped frame structure, the mounting frame 5 includes two brackets and a connecting beam connecting the two brackets, the connecting beam is provided with a mounting hole allowing the filter 4 to be inserted and installed, the two brackets of the mounting frame 5 are respectively connected to the two opposite side walls of the second box body 2, the connecting beam of the mounting frame 5 is close to the cover plate 3, and the filter 4 is inserted between the two brackets through the mounting hole on the connecting beam. The filter 4 is supported and fixed by the mounting frame 5.

[0051] In some embodiments, a handle is provided on the filter screen 4 , and the filter screen 4 can be lifted by the handle to facilitate installation and removal of the filter screen 4 .

[0052] In some embodiments, the filter screen 4 divides the second housing 2 into a first chamber and a second chamber, the inlet 31 is located in the first chamber, and the outlet 32 ​​is located in the second chamber.

[0053] In the above embodiment, the filter 4 separates the inlet 31 into the first chamber and the outlet 32 ​​into the second chamber. The gas carrying paper scraps first enters the first chamber through the inlet 31, and the gas first passes through the water layer. The water can capture and settle most of the larger paper scraps, which plays a preliminary purification role. Then the gas passes through the filter 4 located in the water. The filter 4 can further intercept smaller paper scraps, achieve fine filtration, and improve the paper scrap recovery effect. The gas after secondary filtration enters the second chamber and is discharged through the outlet 32.

[0054] Since the gas has been moistened with water before passing through the filter screen 4, the moist environment helps to reduce the electrostatic effect, making it easier to capture paper scraps, thereby improving the filtering effect.

[0055] In some embodiments, the cover plate 3 is provided with a strip hole 33 that allows the filter screen 4 to pass through and extend into the second box body 2, and the cover plate 3 and the filter screen 4 are provided with a limiting structure that limits each other so that the filter screen 4 is connected to the cover plate 3.

[0056] In the above embodiment, the cover plate 3 and the filter screen 4 are provided with a limiting structure that limits each other, so that after the filter screen 4 is inserted into the second box body 2 through the strip hole 33, it is still connected to the cover plate 3 through the limiting structure and will not be separated from the cover plate 3. When the filter screen 4 needs to be replaced, the filter screen 4 can be directly pulled out from the strip hole 33 without opening the cover plate 3, and the new filter screen 4 can be directly inserted into the second box body 2 through the strip hole 33. Therefore, the filter screen 3 can be replaced without opening the cover plate 3, which is convenient for timely cleaning and replacement of the filter screen 3 to ensure the cleaning of the filter screen 4 and the effect of filtering paper scraps.

[0057] In some embodiments, the limiting structure may include an extension block provided on the top circumference of the filter screen 4. The installation process of the filter screen 4 is that the bottom of the filter screen 4 is first inserted into the strip hole 33. After the extension block reaches the strip hole 33, the extension block and the side wall of the strip hole 33 are engaged and limited, thereby preventing the filter screen 4 from separating from the cover plate 3 and falling into the second box body 2. Of course, the limiting structure is not limited to this.

[0058] In some embodiments, the paper scrap collection and recovery device also includes a first guide tube 6, which is arranged at the inlet 31, the first end of the first guide tube 6 is located on the outside of the cover plate 3, and the second end of the first guide tube 6 is inserted into the second box body 2 and is located above the water surface in the second box body 2.

[0059] In the above embodiment, the water level in the second box body 2 is always slightly lower than the inlet 31, which can ensure the effect of wetting the paper scraps.

[0060] In some embodiments, the paper scrap collection and recovery device further includes a second guide tube 7 , which is disposed at the outlet 32 ​​, wherein the first end of the second guide tube 7 is located outside the cover plate 3 , and the second end of the second guide tube 7 does not exceed the bottom surface of the cover plate 3 .

[0061] In the above embodiment, the second end of the second guide pipe 7 does not exceed the bottom surface of the cover plate 3, and the second end of the second guide pipe 7 is farther away from the water surface than the second end of the first guide pipe 6, so as to discharge the gas more smoothly.

[0062] In some embodiments, the radial dimension of the outlet 32 ​​is greater than the radial dimension of the inlet 31 .

[0063] In some embodiments, the gas pressure at the inlet 31 is greater than the gas pressure at the outlet 32 ​​.

[0064] To ensure that the paper scraps sucked in by the fan can smoothly enter the first box body 1, the gas pressure at the outlet 32 ​​is lower than the gas pressure at the inlet 31, and the silo pressure relief method is adopted to collect the paper scraps, so as to maintain a certain air flow pressure difference between the inlet 31 and the outlet 32 ​​of the first box body 1. Since the air flow rate at the outlet 32 ​​is relatively small, the outlet 32 ​​is designed to be larger than the inlet 31, and an exhaust fan can also be installed at the outlet 32 ​​to maximize the air flow rate at the inlet of the collection box to ensure the effect of the device in collecting paper scraps and paper fibers.

[0065] In some embodiments, the paper scrap collection and recovery device further includes a water replenishment valve 8 , which is disposed in the first box body 1 , and is configured to replenish water into the first box body 1 .

[0066] In the above embodiment, after it is found that the water level in the first box body 1 is lower than the preset value, water is promptly replenished into the first box body 1 through the water replenishment valve 8 .

[0067] In some embodiments, the paper scrap collection and recovery device further includes a liquid level sensor, which is disposed in the first box body 1 and is configured to detect the liquid level height in the first box body 1 .

[0068] In the above embodiment, the liquid level height in the first tank 1 is detected by the liquid level sensor, and when it is found that the water level in the first tank 1 is lower than a preset value, a signal is sent out to replenish water in the first tank 1 in time.

[0069] The first box body 1 in the present invention can be a square box body or a round box body, and the shapes of other parts should be changed accordingly.

[0070] According to the description of the above-mentioned embodiments, the paper scrap collection and recovery device provided by the utility model utilizes the dry and easy-floating characteristics of paper scrap particles and the collection principle of air flow pressure difference dust suction, and utilizes the capillary effect of water's surface tension on fibrous objects, and adopts wet and silo pressure relief methods. It can more effectively collect and recover paper products and paper scraps in production areas, improve paper scrap collection effects, improve production working environment, improve production efficiency, and reduce production costs.

[0071] The paper scrap collection and recycling device provided by the embodiment of the utility model can improve the paper scrap collection effect, improve the production working environment, reduce the failure frequency and product mis-kick rate caused by paper dust, improve production efficiency, improve the quality of printed products, and reduce production costs. The recycled paper mud can also be turned into treasure, and the paper mud and the waste paper generated in the production process can be sold to paper mills for reuse. At the same time, it can also avoid environmental problems caused by direct discharge of paper scraps and paper fibers.

[0072] The paper scrap collection and recovery device provided by the embodiment of the utility model is suitable for the field of paper production and processing or the field where dust is generated during the production process, which can improve the production environment of the enterprise, and can also avoid the impact of excessive paper dust on the quality of printed products, increase the rate of paper product mis-kicks, and increase the rate of equipment failure, thereby improving production efficiency and reducing production costs. It can also collect and treat the dust generated during the production process in a more environmentally friendly and efficient manner, and promote the healthy, safe and efficient development of enterprises.
