Description

Technical Field

[0001] This utility model relates to the field of pulp filtration technology, and in particular to a pulp filtration device for waste paper recycling. Background Technology

[0002] When recycling waste paper, water is added to a container along with the waste paper and other impurities. Through mechanical stirring, the waste paper is initially turned into pulp. During this process, the waste paper fibers are dispersed into pulp suspended in the water through shearing, friction, and impact. Some plastic and fibrous impurities are not dispersed and float in the pulp. The stirred pulp and impurities are then fed into a pulping tank. Before the subsequent fine screening step, larger impurities in the pulping tank need to be removed for coarse screening. Therefore, a filter device similar to a sieve is used to remove the impurities. The pulp flows out through the gaps in the filter device, while the impurities remain in the filter device. However, the limited inlet of the filter device reduces the efficiency of pulp processing. Utility Model Content

[0032] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0033] Example 1

[0034] Reference Figures 1-3 This is the first embodiment of the present invention, which provides a pulp filtration device for waste paper recycling. The pulp filtration device for waste paper recycling includes a main component 100, including a frame 101. A baffle 102 is rotatably connected to the frame 101. The top of the baffle 102 is hollow between the top of the frame 101 and the top of the frame 101, which serves as the inlet of the filtration device. Multiple baffles 103 are fixed on the frame 101, and there is a certain gap between adjacent baffles 103, allowing pulp to flow through the gap. The impurities flow out of the frame 101 through the gap, while larger impurities will be blocked by the baffle 103 and remain inside the frame 101, where they are blocked by the door 102. A door lock mechanism 105 is fixed on one side of the frame 101, which can cooperate with the door 102 to close the door 102 and the frame 101, so that the impurities can be collected inside the frame 101. During the collection process, the upper part of the frame 101 will not enter the pulp. After collection is completed, the door 102 can be opened to remove the impurities.

[0035] A connecting column 104 is fixed to the top of the frame 101. The connecting column 104 is used to connect the lifting component that drives the frame 101 to rise and fall, thereby enabling the frame 101 to rise and fall.

[0036] The moving component 200 is disposed on the frame 101 and includes a moving part 201. The moving part 201 is disposed to push impurities located around the frame 101 to the inlet of the filter device.

[0037] The movable component 201 includes a side plate 2011 disposed on one side of the frame 101, a connecting rod 2012 fixed on the side plate 2011, a cylinder 2013 fixed on the frame 101, and a telescopic column 2014 disposed on one side of the cylinder 2013. The telescopic column 2014 is fixed on the connecting rod 2012. The cylinder 2013 is used to move the side plate 2011 closer to or away from the side of the frame 101. Before the frame 101 is placed into the pulp tank, the telescopic column 2014 is in an extended state. At this time, the side plate 2011 is located away from the frame 101. After the frame 101 is placed into the pulp tank and the baffle 102 is filled with pulp, the cylinder 2013 is activated to move the telescopic column 2014, thereby moving the connecting rod 2012 and the side plate 2011 closer to the frame 101.

[0038] The moving assembly 200 also includes a gathering member 202 located on the side plate 2011. The gathering member 202 is configured to allow impurities located in front of and to the side of the frame 101 to enter the inlet of the filter device.

[0039] A first slide groove 2011-1 is provided on the side plate 2011. A first fixed shaft 2021 is fixed on the first slide groove 2011-1. A first slider 2022 is sleeved on the first fixed shaft 2021. The first fixed shaft 2021 allows the first slider 2022 to move smoothly within the first slide groove 2011-1. A fixed sleeve 2023 is fixed on the first slider 2022. The fixed sleeve 2023 is used to push the impurities located on the side of the frame 101 and bring them closer to the inlet of the filter device. A first spring 2024 is fixed on one side of the first slider 2022. The first spring 2024 applies a continuous pulling force to the first slider 2022.

[0040] In the initial state, the position of the first slider 2022 is locked in the first slide groove 2011-1, away from the gate 102. When the position of the first slider 2022 is unlocked, under the pull of the first spring 2024, the first slider 2022 will slide along the first fixed shaft 2021 towards the gate 102, thereby driving the fixed sleeve 2023 to move. When the fixed sleeve 2023 moves, it can push the floating impurities closer to the gate 102.

[0041] Example 2

[0042] Reference Figures 4-10 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0043] Specifically, a second slide groove 2011-2 is provided on the side plate 2011. A second fixed shaft 2025 is fixed in the second slide groove 2011-2. A second slider 2026 is sleeved on the second fixed shaft 2025. The second slider 2026 can move smoothly in the second slide groove 2011-2 along the direction of the second fixed shaft 2025. A fixed plate 2027 is fixed to the second slider 2026. The fixed plate 2027 is used to drive the impurities located in front of the frame 101 into the inlet of the filter device. A second spring 2028 is fixed on one side of the second slider 2026. The second spring 2028 applies a continuous pulling force to the second slider 2026.

[0044] In the initial state, the position of the second slider 2026 is locked away from the gate 102. After the position of the second slider 2026 is released, under the pull of the second spring 2028, the second slider 2026 will drive the fixed plate 2027 to move closer to the gate 102, thereby allowing impurities to enter the machine frame 101.

[0045] Specifically, the moving component 200 also includes a locking element 203 located inside the side plate 2011. The locking element 203 is used to lock the initial positions of the first slider 2022 and the second slider 2026. The side plate 2011 has a first moving groove 2011-3, and a locking block 2031 is provided in the first moving groove 2011-3. The first slider 2022 has a locking groove 2022-1. When the locking block 2031 engages with the locking groove 2022-1, the position of the first slider 2022 will be locked in the first sliding groove 2011-1 at a position away from the stop 102. A third spring 2032 is fixed on one side of the locking block 2031. The third spring 2032 ensures that the locking block 2031 can engage with the locking groove 2022-1.

[0046] One end of the locking block 2031 is inclined, and the locking groove 2022-1 has a corresponding shape. The inclined setting allows the end face of the first slider 2022 to contact the inclined surface of the locking block 2031 first when the first slider 2022 is pushed to reset. The third spring 2032 will be compressed, and the locking block 2031 will not hinder the movement of the first slider 2022. When the locking block 2031 and the locking groove 2022-1 are in a coaxial position, they will engage under the push of the third spring 2032, thereby restricting the movement of the first slider 2022.

[0047] Specifically, an extrusion plate 2033 is fixed on the frame 101, a first inclined groove 2031-1 is provided on the locking block 2031, one end of the extrusion plate 2033 is inclined, the extrusion plate 2033 can be engaged with the first inclined groove 2031-1, and a through groove 2011-6 corresponding to the extrusion plate 2033 is provided on the side plate 2011.

[0048] When the cylinder 2013 drives the telescopic column 2014 to move, thereby causing the connecting rod 2012 and the side plate 2011 to move closer to the frame 101, the inclined surface of the extrusion plate 2033 will first contact the first inclined groove 2031-1 and extrude the first inclined groove 2031-1, thereby causing the locking block 2031 to move upward and away from the locking groove 2022-1, thereby releasing the limit of the first slider 2022.

[0049] Specifically, the side plate 2011 has a second moving groove 2011-4, and a locking block 2034 is provided in the second moving groove 2011-4. The second slider 2026 has a locking groove 2026-1. When the locking block 2034 and the locking groove 2026-1 are engaged, the movement of the second slider 2026 will be restricted. A fourth spring 2035 is fixed on one side of the locking block 2034. The fourth spring 2035 ensures that the locking block 2034 can engage with the locking groove 2026-1.

[0050] One end of the locking block 2034 is inclined, and the locking groove 2026-1 has a corresponding shape. The inclined setting is used so that when the second slider 2026 is pushed to reset, the end face of the second slider 2026 first contacts the locking block 2034 and squeezes it. At this time, the locking block 2034 will not hinder the movement of the second slider 2026. When the locking block 2034 and the locking groove 2026-1 are coaxial, the two will be locked together under the action of the fourth spring 2035, thereby restricting the fourth spring 2035.

[0051] Example 3

[0052] Reference Figure 1-10 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0053] Specifically, a sliding groove 2011-5 is provided on the side plate 2011, and a push block 2036 is provided in the sliding groove 2011-5. A second inclined groove 2034-1 is provided on the locking block 2034. One end of the push block 2036 is inclined, and the inclined surface of the push block 2036 can fit into the second inclined groove 2034-1. The push block 2036 is used to unlock the locking of the second slider 2026.

[0054] In the initial state, one end face of the push block 2036 will be located in the second slide groove 2011-2. When the first slider 2022 contacts the limit, the first spring 2024 pulls the first slider 2022 to slide closer to the stop gate 102. The first slider 2022 will first fit with the push block 2036 and push the push block 2036 to move closer to the locking block 2034, and then contact and squeeze the second inclined groove 2034-1, thereby causing the locking block 2034 to move upward and away from the locking groove 2026-1, thereby releasing the locking of the second slider 2026.

[0055] An auxiliary block 20213 is fixed on the push block 2036, and a sixth spring 20214 is fixed on one side of the auxiliary block 20213. The two work together to reset the auxiliary block 20213.

[0056] Specifically, a sliding sleeve 2029 is provided inside the fixed sleeve 2023, and a sliding block 20210 is provided inside the sliding sleeve 2029. A fifth spring 20211 is fixed on one side of the sliding sleeve 2029, and a fifth spring 20211 is also provided on one side of the sliding block 20210. One end face of the sliding block 20210 is always in contact with the frame 101. Through the cooperation of the fixed sleeve 2023, the sliding sleeve 2029 and the sliding block 20210, the length between the three can be adjusted according to the position of the fixed sleeve 2023 and the frame 101. When the cylinder 2013 drives the side plate 2011 to move closer to the frame 101, the three can push the impurities on the side of the frame 101 toward the inlet of the filter device.

[0057] Specifically, there are two guide posts 2015 fixed on the frame 101. The side plate 2011 is provided with guide grooves corresponding to the guide posts 2015 to ensure that the side plate 2011 can move smoothly when the cylinder 2013 drives the side plate 2011 to move.

[0058] Specifically, there are two sets of moving components 200, symmetrically distributed on the frame 101, so that impurities located on both sides of the frame 101 can enter the filtration device.

[0059] Specifically, protective covers 20212 are provided inside the first slide 2011-1 and the second slide 2011-2. There are two protective covers 20212. One of them is fixed at both ends to the first slide 2011-1 and the first slider 2022, respectively. The other is fixed at both ends to the second slide 2011-2 and the second slider 2026, respectively. The protective cover 20212 is similar to a louver and can be extended and retracted to prevent large particles in the pulp from entering the first slide 2011-1 and the second slide 2011-2 and coming into contact with the first spring 2024 and the second spring 2028.

[0060] In use, before the frame 101 is placed into the pulp tank, the telescopic column 2014 is in an extended state, and the side plate 2011 is located away from the frame 101. After the frame 101 is placed into the pulp tank and the baffle 102 is submerged in pulp, the cylinder 2013 is activated to move the telescopic column 2014, thereby moving the connecting rod 2012 and the side plate 2011 closer to the frame 101. The inclined surface of the extrusion plate 2033 will first contact the first inclined groove 2031-1 and extrude the first inclined groove 2031-1, thereby moving the locking block 2031 upward away from the locking groove 2022-1, thereby releasing the limit of the first slider 2022. Under the pull of the first spring 2024, the first slider 2022 will slide along the first fixed shaft 2021 towards the baffle 102, thereby moving the fixed sleeve 2023. When the fixed sleeve 2023 moves, it can push the floating impurities closer to the inlet of the filter device.

[0061] When the first slider 2022 moves, it first comes into contact with the push block 2036 and pushes the push block 2036 toward the direction of the locking block 2034, and contacts and squeezes the second inclined groove 2034-1, thereby causing the locking block 2034 to move upward and away from the locking groove 2026-1, thereby releasing the locking of the second slider 2026. Under the pull of the second spring 2028, the second slider 2026 will drive the fixing plate 2027 toward the direction of the baffle 102, thereby allowing impurities to enter the frame 101, thereby improving the efficiency of impurities entering the filtration device.

[0062] After collection is completed, the rack 101 is lifted and placed in the designated position, the baffle 102 is opened to remove the impurities, and then the first slider 2022 and the second slider 2026 are reset for the next use.

[0063] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
